[0001] The present invention relates to a sliding-sliding door opening / closing device / apparatus that moves a door panel in a front-to-back direction of a door-opening device. vehicle and a vehicle width direction and a tilting-sliding door device comprising the tilting-sliding door opening-closing apparatus. BACKGROUND Japanese Patent Publication No. 2008-121244 discloses an example of a conventional sliding and sliding door device for a railway vehicle. The tilting-sliding door device comprises a tilting-sliding door opening-closing apparatus which performs an operation for moving gates in the width direction of a railway vehicle when sliding the door in the forward direction. rear of the railway vehicle, namely, the so-called swaying operation. The tilting-sliding door device includes a locking mechanism that restricts movement of the doors in the front-to-rear direction of the vehicle and in the width direction when the doors are completely closed and completely covers an entrance on a side wall of the vehicle. vehicle. SUMMARY The locking mechanism is configured to restrict movement of door suspenders coupled to upper end portions of the doors. For example, when lower end portions of the doors receive a high force that exerts pressure on the doors outward in the width direction of the vehicle, the lower end portions of the doors are displaced outwardly. in the direction of the width of the vehicle. This can form a gap between the lower end portions of the doors and the entrance. If the rigidity of the door and the locking mechanism is increased so that such displacement and deviation are avoided, the doors and locking mechanism become heavier. This could interfere with the assembly of a door device. An object of the present invention is to provide a tilting-sliding door opening-closing apparatus and a tilting-sliding door arrangement which limit a door movement in the width direction of the vehicle upon receipt of a door. an excessive external force without the need for increased door rigidity and locking mechanism. One aspect of the present invention is a tilting-sliding door opening-closing apparatus which comprises a locking mechanism, a drive mechanism, and a door support mechanism. The locking mechanism is directly or indirectly arranged on one of an upper portion and a lower portion of at least one door of a vehicle. The locking mechanism locks the door when the door is completely closed so that the door does not open. The drive mechanism is coupled to the locking mechanism. The drive mechanism drives the lock mechanism to switch the door from an unlocked state to a locked state. The door support mechanism is mechanically coupled to the locking mechanism and supports the door. When the fully closed door is toggled from the unlocked state to the locked state, the door support mechanism is adapted to hold the door and prevent outward movement, in a direction of the vehicle width, of the door. other of the upper part and the lower part of the door which is not provided with the locking mechanism. In the above structure, even when a door receives a high force which exerts pressure on the door outward in the width direction of the vehicle, the door support mechanism prevents outward movement, in the direction of the width of the vehicle, the upper part and the lower part of the door. This limits the formation of spacing between a vehicle sidewall of the vehicle and the door. The rigidity of the door and locking mechanism need not be improved. In some implementations, the tilting-sliding door opening-closing apparatus further comprises at least one tilting arm mechanism which guides movement of the door in the direction of the width of the vehicle. The door support mechanism holds the door by restricting movement of the swing arm mechanism.
[0002] In the above structure, the door support mechanism restricts a movement of the swinging arm mechanism arranged on the edge of the vehicle sidewall, which is adjacent to an opening of the vehicle. The door support mechanism can therefore be arranged on the side wall of the vehicle, which is adjacent to the opening. This widens the opening of the side wall of the vehicle. In some implementations of the sliding-sliding door opening-closing apparatus, the door support mechanism includes a restriction member which restricts movement of a movable portion of the swing arm mechanism to restrict movement of the door mechanism. swinging arm. In cooperation with the tilting of the locking mechanism, the restriction member is movable to a restriction position, wherein the restriction member restricts movement of the tilting arm mechanism, and a non-restriction position, where the element restriction does not restrict movement of the swing arm mechanism. In some implementations of the swivel-slide door open-close apparatus, the restriction member is in contact with the movable portion at the restriction position. The above structure further limits the formation of spacing between the vehicle side body and the door as compared to the case in which a gap is formed between the restriction member and the movable portion when the restriction member is located at the restriction position. In some implementations of the sliding-sliding door opening-closing apparatus, the driving mechanism is directly or indirectly arranged on the upper part of the door. The movable portion defines an upper portion of the swing arm mechanism.
[0003] The above structure allows the drive mechanism and the restriction member to be located close to each other in comparison with a structure in which the restriction member is in contact with a lower portion. the swing arm mechanism to restrict movement of the swing arm mechanism. The driving force of the drive mechanism can thus easily be transmitted to the restriction element. In some implementations of the sliding-sliding door opening-closing apparatus, the door support mechanism further comprises a movable support and a coupling rod. The movable support is coupled to one of the locking mechanism and the drive mechanism and moves in a forward-to-back direction of the vehicle. The coupling rod extends in the front-rear direction of the vehicle and couples the movable support and the restriction member.
[0004] The above structure stabilizes the operation of the door support mechanism in comparison with a structure in which the driving force is transmitted to the restriction element from the locking mechanism or drive mechanism, for example , using cables. In some implementations of the sliding-sliding door opening-closing apparatus, the coupling rod includes a length adjustment mechanism. In the above structure, the position of the restriction member may be adjusted relative to the movable portion of the swing arm mechanism in the front-rear direction of the vehicle by adjusting the length of the coupling rod. Thus, even after assembly of the sliding-sliding door opening-closing apparatus, the position of the restriction element can be changed easily so that the displacement in the direction of the width X is furthermore suitably limited in the upper or lower end portion of the door. In some implementations of the swivel-slide door opening-closing apparatus, the door support mechanism further includes at least one support member attached to the vehicle. The support member is adapted to support the coupling rod and prevent outward deformation, in the vehicle width direction, of the coupling rod. A movement of the tilting arm mechanism may apply a high force exerting a pressure on the coupling rod outward in the direction of the width of the vehicle. This would deform the coupling rod, and such deformation will cause the restriction member to move relative to the rocking arm mechanism. In this regard, in the above structure, the support member prevents movement of the restriction member by limiting deformation of the coupling rod. The restriction member therefore maintains the function of restricting a movement of the movable portion of the swing arm mechanism appropriately. In some implementations of the swivel-slide door open-close apparatus, the at least one support member includes a plurality of support members that support the coupling rod at different positions in the forward-back direction. of the vehicle. The restriction member is located between two adjacent support members among the support members. In the above structure, the opposite ends of the restriction member, which receives a force from the tilting arm mechanism, are supported in the front-to-rear direction of the vehicle. This further limits the deformation of the coupling rod in the direction of the width of the vehicle. In some implementations of the sliding-sliding door opening-closing apparatus, the door support mechanism further includes a guide member which guides movement of the movable support in the front-rear direction of the vehicle. In the above structure, when a force is applied to the door, the force is received by the guide member. This prevents the force, which is applied to the door, from being transmitted to the locking mechanism. Thus, the locking mechanism is stably maintained in the locked state. In addition, the movable support moves smoothly in the front-to-back direction due to the guide member. The locking mechanism can therefore be flipped smoothly to the locked state and to the unlocked state. In particular, the load can be reduced when an operator manually switches the state. In some implementations of the sliding-sliding door opening-closing apparatus, said at least one door comprises two doors, and said at least one swinging arm mechanism comprises two rocking arm mechanisms, which respectively correspond to the two doors. The door support mechanism 25 comprises two of the restriction elements which respectively correspond to the two swing arm mechanisms and two of the coupling rods which respectively correspond to the two swing arm mechanisms. In the above structure, the two restriction elements can be moved simultaneously by moving the coupling rod. This simplifies the task of manually opening and closing the door as compared to the case in which an operator moves the restriction elements individually. In some implementations of the sliding-sliding door opening-closing apparatus, the tilting arm mechanism includes an upper tilting arm facing outward in the direction of the width of the vehicle about an axis of rotation. extending in a height direction upon receiving a force which moves the door outward in the direction of the width of the vehicle. The movable portion includes the upper tilting arm. In some implementations of the tilting-sliding door closure apparatus, the tilting arm mechanism further includes a lower tilting arm and a pillar. The lower tilting arm supports the lower part of the door and guides movement of the door when it is turned outward in the direction of the width of the vehicle about an axis of rotation extending in the direction of the door. height. The pillar couples the upper tilting arm and the lower tilting arm. In the above structure, the force required to restrict movement of the swing arm mechanism is decreased in comparison with the case where the door support mechanism directly applies a force to the pillar. This eliminates the need to increase the rigidity of the door support mechanism. The door support mechanism can therefore be reduced in size. In addition, rotation of the lower rocker arms is restricted in addition to rotation of the upper rocker arms. This prevents the formation of a gap between the lower end portion of the door and the side wall of the vehicle.
[0005] In some implementations, the tilting-sliding door opening-closing apparatus further includes a pressed portion coupled to the door. When the locking mechanism locks the door, the pressed portion contacts the lower swing arm and is pressed toward a door closing side. In the above structure, when the locking mechanism is in the locked state, movement to the opposite side in the front-to-rear direction of the vehicle, i.e., the door opening side, is limited in the lower part of the door. In some implementations of the sliding-sliding door opening-closing apparatus, the pressed portion includes a contact surface that is in contact with the lower tilting arm, and the contact surface is inclined with respect to the forward direction. rear of the vehicle. The tilting-sliding door opening-closing apparatus further comprises a roller coupled to the lower tilting arm and a lower sliding rail coupled to the lower portion of the door and extending in the front-to-rear direction of the vehicle. The lower tilting arm supports the lower slide rail through the roller which is in contact with the lower slide rail from at least one inner side in the width direction of the vehicle. In the above structure, as the door moves in the front-to-rear direction of the vehicle, the lower slide rail moves smoothly with respect to the lower rocker arm. In addition, when the door is closed, the lower tilting arm receives an outward component, in the direction of the width of the vehicle, the force acting on the pressed portion. An outward movement in the direction of the width of the vehicle is therefore limited in the door.
[0006] In some implementations of the tilting-sliding door opening-closing apparatus, the tilting arm mechanism further includes a restricted rod that is coupled to the upper tilting arm and extends in the height direction. The restriction member restricts rotation of the upper rocker arm by limiting movement of the restricted rod to the restriction position.
[0007] In the above structure, the position in which the restriction member is in contact with the restricted rod can be selected within a range of the restricted rod length. This increases the degree of freedom for the design of the position in which the restriction element is located in the direction of the height. In some implementations of the sliding-sliding door opening-closing apparatus, the rocking arm mechanism further includes a rod wheel rotatably coupled to the restricted rod. The restriction member restricts movement of the restricted rod when in contact with the stem wheel. In the above structure, as the restriction member moves in the front-rear direction of the vehicle, the pin wheel contacts the restriction member and rotates. This reduces the frictional force between the restriction member and the stem wheel. The restriction element thus contacts and separates from the restricted rod in a fluid manner. In some implementations, the tilting-sliding door opening-closing apparatus further comprises a guide arm which moves the door in the direction of the width of the vehicle when it is rotated about an axis of rotation. extending in the direction of the height. The restricted rod is coupled to the guide arm.
[0008] In the above structure, the restricted rod is coupled to the upper tilting arm and the guide arm. This limits a deformation of the restricted rod. Movement of the movable part of the swing arm mechanism is therefore stably restricted. In some implementations, the tilting-sliding door opening-closing apparatus further comprises an auxiliary arm coupled to the upper tilting arm to be rotatable about an axis of rotation extending in the direction of height. The auxiliary arm adjusts a position of the upper swing arm relative to the guide arm. The restricted rod, which is coupled to the auxiliary arm, indirectly couples the restricted rod to the upper rocker arm. In the above structure, even when errors in the rotational positions of the upper tilting arm and the guide arm occur, such errors can be compensated by rotating the auxiliary arm relative to the upper tilting arm when assembly of the swing arm mechanism. In some implementations of the sliding-sliding door opening-closing apparatus, the auxiliary arm includes a length adjustment mechanism. In the above structure, the position of the movable portion of the tilt arm mechanism can be adjusted relative to the restriction member by adjusting the length of the auxiliary arm. Even after assembly of the sliding-sliding door opening-closing apparatus, the position of the movable part of the swing arm mechanism can thus be easily changed so that the displacement in the width direction is further suitably limited in another part of the door. In some implementations of the sliding-sliding door opening-closing apparatus, the restriction member comprises a flat surface which extends in the front-rear direction of the vehicle, and the flat surface is in contact with the moving part. In the above structure, even when a force exerting pressure on the restriction member outward in the width direction of the vehicle is applied from the movable portion of the swing arm mechanism to the restriction element, the formation of a component of the force, which acts in the front-rear direction of the vehicle, is limited. This decreases the situations in which the restriction member is moved to the unrestricted position due to the force applied to the door or the like in the locked state. In some implementations of the sliding-sliding door opening-closing apparatus, the restriction member includes a sloped surface at a portion through which the movable portion passes during movement of the non-restrictive position. to the restriction position. The inclined surface is continuous with the flat surface and is inclined outwardly in the direction of the width of the vehicle from the flat surface. In the above structure, as the restriction member moves from the non-restriction position to the restriction position, the inclined surface of the restriction member contacts the movable portion. The movable portion is thus moved along the inclined surface and guided toward the planar surface of the restriction member. This moves the moving part to the flat surface in a fluid manner. In some implementations of the sliding-sliding door opening-closing apparatus, the drive mechanism also functions as a drive source that opens and closes the door. The driving force of the drive mechanism for moving the door is greater than the driving force that is output from a drive source dedicated to a locking mechanism. Such a high driving force is used to drive the door support mechanism. An outward movement in the direction of the width of the vehicle is therefore additionally limited in the upper end portion or in the lower end portion of the door. In addition, the number of drive sources in the tilting-sliding door opening-closing apparatus can be reduced in comparison with the case in which a drive source dedicated to the locking mechanism is provided. Another aspect of the present invention is a tilting-sliding door device which comprises a vehicle door and one of the above-mentioned sliding-sliding door opening-closing apparatus which opens and closes the door. In some aspects of the present invention, even when the door receives a high force exerting pressure on the door outwardly in the width direction of the vehicle, door movement can be decreased in the width direction. of the vehicle without increases in the rigidity of the door and the locking mechanism. Other aspects and advantages of the invention will become apparent from the following description, taken in conjunction with the accompanying drawings, illustrating by way of example the principles of the invention.

DESCRIPTION OF EMBODIMENTS Referring to FIG. 1, a sliding-sliding door device 1 for a vehicle 200, which may be a rail vehicle, will now be described. In the description, hereinafter, the X, Y, Z axes in the orthogonal coordinate system of FIG. 1 refer to a vehicle width direction X, a vehicle front-to-back direction Y, and a vehicle height direction Z, respectively. The direction of width X may refer to a direction of sway movement and an anti-sway motion direction of doors 2R, 2L. In some examples, the direction of the width X refers to a direction that is intersected with or perpendicular to an outer or inner surface of each of the doors 2R, 2L. The front-rear direction Y may refer to a direction of sliding movement of the doors 2R, 2L. The front-rear direction Y may refer to a direction of sliding movement of the doors 2R, 2L. In some examples, the front-back direction Y refers to a horizontal direction that is substantially parallel to the outer or inner surface of each of the doors 2R, 2L. In the present description, the terms "right side" and "left side" correspond respectively to the right side and to the left side when the sliding door-sliding device 1 is seen from inside the vehicle 200 and are defined as shown in FIG. 1. In the present description, reference signs ending with a letter "L" or "R" may be assigned to the components of the tilting-sliding door device 1 which are matched to the left and right sides. Figs. 1 to 6, 8, 10 and 11 each show a completely closed state in which the doors 2L, 2R completely cover an opening provided for a vehicle side wall 210 of the vehicle 200, or an inlet 211. The sliding and sliding door device 1 comprises the double sliding doors 2L, 2R, which open and close the inlet 211, and a sliding-sliding door opening-closing apparatus 10, which drives or moves the doors 2L, 2R in the direction of the width X and in the forward-backward direction Y. The tilting-sliding door device 1 comprises two tilt arm mechanisms 20L, 20R which guide a movement of the doors 2L, 2R in the direction of the width X and in the forward-back direction Y In some examples, the doors 2L, 2R are flush with the outer surface of the side wall of the vehicle 210 when fully closed.
[0010] As shown in FIG. 2, the tilting-sliding door opening-closing apparatus 10 is located at an upper side of the entrance 211 and comprises a base extending in the forward-backward direction Y. The base 11 is supported by a support frame 12, which is located at a position corresponding to an upper end portion of the doors 2L, 2R and a middle portion of the base 11 in the front-back direction Y. The support frame 12 is attached to the side wall 210 of the vehicle. A drive mechanism 13 and a locking mechanism 40 are located on the base 11. The drive mechanism 13 moves the doors 2L, 2R in the direction of the width X and in the front-rear direction Y. The mechanism of lock 40 locks the doors 2L, 2R so that the doors 2L, 2R do not open when they are completely closed. The drive mechanism 13 drives the locking mechanism 40 so that the doors 2L, 2R are switched from an unlocked state to a locked state. Alternatively, the drive mechanism 13 may drive the locking mechanism 40 so that the doors 2L, 2R are switched from the locked state to the unlocked state. The drive mechanism 13 includes a motor (not shown), which is located in the support frame 12, and a planetary gear mechanism (not shown), which is connected to an output shaft of the motor. The output shaft of the motor and each gear in the planetary gear mechanism rotate about an axis of rotation extending in the direction of the height Z. Although not shown in the drawings, the planetary gear mechanism may include a pinion gear, which functions as a first output part, and a carrier, which functions as a second output part. The pinion gear is engaged with two 14L, 14R rack gears. The rack gears 14L, 14R are located at the same height and are separated in the direction of the width X. The rack gear 14L extends to the left from the middle of the opening-closing apparatus of sliding-sliding door 10 in the front-rear direction Y. The rack gear 14R, which is located at an inner side of the rack gear 14L in the width direction X, extends towards the right from the middle of the sliding-sliding door opening-closing apparatus 10 in the front-rear direction Y. The driving mechanism 13 may have the same structure as the rack and pinion mechanism, planetary gear, motor, and tilting mechanism for tilting an output of the planetary gear mechanism which are described in Japanese Patent Publication No. 2008121244 issued. In published Japanese Patent No. 2008-121244, the motor and the gears and the carrier in the planetary gear mechanism are configured to rotate about axes of rotation extending in the direction of the width X. In contrast, in the embodiment, the motor and the gears and the carrier in the planetary gear mechanism of the drive mechanism 13 rotate about axes of rotation extending in the direction of the height Z. A suspension device of 15L door, which is attached to the door 2L, is attached to a left end of the rack gear 14R. In the same way, a door suspension device 15R is attached to a right end of the rack gear 14L. Each of the door suspension devices 15L, 15R moves in the direction of the width X and in the front-back direction Y along a corresponding inclined rail of two inclined rails, which are included in the base 11.
[0011] The door suspension devices 15L, 15R each comprise a first coupling plate 15A, which is coupled to the corresponding rack gear of the rack gear 14L, 14R, and a second coupling plate 15B, which extends into the direction of the width X and is coupled to the corresponding door among the doors 2L, 2R. Each first coupling plate 15A is L-shaped and has an inner end, in the direction of the width X, extending in the direction of the height Z. A shaft 15C extending in the direction of the width X is coupled to the inner end of each first coupling plate 15A in the width X direction. A roller 15D, which moves along the corresponding inclined rail, is coupled to the lower surface of each second coupling plate 15B. Suspender guiding mechanisms 16L, 16R, which guide movement of the corresponding door suspenders 15L, 15R in the width X direction, are each coupled to the upper surface of the corresponding second coupling plate 15B. The suspension guide mechanisms 16L, 16R each comprise a rail 16A, which is attached to the corresponding first coupling plate 15A, and a slide 16B, which is attached to the corresponding second coupling plate 15B. Each rail 16A extends in the direction of the width X. Each slider 16B is engaged with the corresponding rail 16A and is movable in the width direction X along the rail 16A. This structure allows each second coupling plate 15B to move relative to the corresponding first coupling plate 15A in the width direction X and integrally with the first coupling plate 15A in the front-back direction Y. Each shaft 15C moves in solidarity with the corresponding first coupling plate 15A.
[0012] As shown in FIG. 3, which does not show the base 11 and the support frame 12, the swing arm mechanisms 20L, 20R are located on the edges of the vehicle side wall 210 which are adjacent to the inlet 211 in the front-to-back direction Y, i.e., the leading edge and the trailing edge of the inlet 211. The rocking arm mechanisms 20L, 20R each comprise two guide arms 21 (see Fig. 3), which support upper end of the corresponding door among the doors 2L, 2R. The two guide arms 21 of each swing arm mechanism are located on two opposite ends, in the front-rear direction Y, of the corresponding one of the doors 2L, 2R and are fixed to the base 11. The two guide arms 21, which are associated with each door, can be referenced as the guide arm of the opening side and the guide arm of the closing side.
[0013] The distal end of each guide arm 21 is coupled to an arm coupling member 22, which is coupled to the corresponding arm guide mechanism among the two arm guide mechanisms 17L, 17R. The arm guiding mechanisms 17L, 17R are each coupled to the upper end portion of the corresponding one of the doors 2L, 2R. The arm guiding mechanisms 17L, 17R each comprise a guide rail (not shown), which is coupled to the corresponding one of the doors 2L, 2R, and a support body 17A, which is movable relative to the guide rail in the front-back direction Y. Each arm coupling member 22 is coupled to the corresponding support body 17A. When the doors 2L, 2R move in the front-rear direction Y, the guide rails of the doors 2L, 2R move in the front-back direction Y with respect to the support bodies 17A of the arm guiding mechanisms 17L, 17R . The guide arms 21 and the arm coupling members 22 therefore support the doors 2L, 2R in the width X direction. As shown in FIG. 4, the tilting arm mechanisms 20L, 20R each comprise a pillar 23, which extends in the direction of the height Z. Each pillar 23 is located at the door opening side of the guide arm 21 on the left side. corresponding door opening. The upper and lower end portions of each pillar 23 are rotatably coupled to upper and lower supports 24, respectively, which are attached to the side wall of the vehicle 210 (see Fig. 3). A lower rocker arm 25 is non-rotatably coupled to a portion of each pillar 23 which is located above and adjacent to the corresponding lower support 24. Each lower rocker arm 25 supports a lower end portion of the corresponding one of the gates 2L, 2R (see Fig. 2). The distal end of each lower tilting arm 25, which is connected and secured to the lower end portion of the corresponding one of the doors 2L, 2R, supports the corresponding lower slide rail among the lower slide rails 30L, 30R. , which extend in the front-rear direction Y. A coupling mechanism 50, which is coupled to the upper end portion of each pillar 23, rotates the pillar 23 in accordance with the rotation of the corresponding guide arm 21. . The coupling mechanism 50 couples the pillar 23 and the guide arm 21 of the door opening side. As shown in FIG. 5, the lower slide rail 30R is U-shaped and opens downward to form a groove. The lower slide rail 30R includes an outer wall 31, which is attached to the door 2R (see Fig. 3), an inner wall 32, which is inwardly spaced in the direction of the width X of the outer wall 31 and an upper wall 33, which connects an upper end portion of the outer wall 31 and an upper end portion of the inner wall 32. A pressed portion 34 is coupled to the end of the door opening side. of the outer wall 31 with a bolt. Pressed portion 34 includes a lower portion extending downwardly beyond outer wall 31. Lower portion of pressing portion 34 includes a contact surface 34A, which is inclined inwardly in the direction of the width X as it extends towards the door closing side, and a flat surface 34B, which extends in the front-back direction Y between the contact surface 34A and the end of the door closing side. As shown in FIG. 6, the flat surface 34B and an outer surface 32A of the inner wall 32 are aligned on the same plane in a view from below. Here, the lower slide rail 30L has the same structure as the lower slide rail 30R. As shown in FIG. 5, a roller 26 is coupled to the distal end of the lower tilting arm 25. The roller 26 is movable with respect to the lower slide rail 30R in the front-rear direction Y as it rotates about an axis of rotation s' extending in the direction of the height Z. The roller 26, which protrudes upwardly from an upper surface of the distal end of the lower tilting arm 25, is located between the outer wall 31 and the inner wall 32 of the sliding rail corresponding lower.
[0014] A roller 27 is rotatably coupled to a lower surface of the lower tilting arm 25 which is separated from the distal end of the lower tilting arm 25 towards the door opening side. The roller 27 is movable relative to the pressed portion 34 as it rotates about an axis of rotation extending in the direction of the height Z. As shown in FIG. 6, the roller 27 is arranged to be in contact with the contact surface 34A. The roller 27 exerts pressure on the pressed portion 34 toward the door closing side. As shown in FIG. 7, when the door 2R (see Fig. 3) moves outward and toward the door opening side, the lower swing arm 25 turns outward and toward the door opening side so that that the lower tilting arm indicated by the solid lines is moved to the lower tilting arm indicated by the dashed lines. As the door 2R moves outward and toward the door opening side, the roller 26 rolls on the inner wall 32 of the lower slide rail 30R. This moves the door 2R relative to the roller 26 and the lower swing arm 25 towards the door opening side in the front-back direction Y. When the door 2R moves outwards and towards the opening side of the door door, the roller 27 moves inward in the direction of the width X along the contact surface 34A (the roller 27 does not have to be in contact while rolling) and towards the closing side of the door relative to the contact surface 34A. After passing through the contact surface 34A in the forward-backward direction Y, the roller 27 rolls on the flat surface 34B towards the door closing side. With reference to FIG. 8, each coupling mechanism 50 comprises an upper rocking arm 51 of the corresponding rocking arm mechanism among the swing arm mechanisms 20L, 20R. The upper tilting arm 51 is coupled to the upper end portion of the corresponding abutment 23 below the upper support 24. The upper tilting arm 51 can not rotate relative to the abutment 23. The distal end of the upper tilting arm 51 is coupled to the distal end of the guide arm 21 by an auxiliary arm 52. The auxiliary arm 52 is rotatable relative to the upper tilting arm 51 about an axis of rotation extending in the direction of the Z height. Each auxiliary arm 52 includes an arm length adjustment mechanism 53, which can adjust its length, i.e., the distance between a base portion 54 and a distal portion 55 of the auxiliary arm 52. Each mechanism arm length adjustment device 53 comprises a rod-shaped bolt 53A, and two nuts 53B, which are fixed to the bolt 53A. A change in the position of the nuts 53B relative to the bolt 53A changes the insertion amount of the bolt 53A in the base portion 54 and the distal portion 55. Therefore, the length of the auxiliary arm 52 is changed. In this manner, the relative position of the auxiliary arm 52 and the guide arm 21 can be adjusted as the auxiliary arm 52 is rotated relative to the upper tilting arm 51 to adjust the length of the auxiliary arm 52. The distal portion 55 of each auxiliary arm 52 is coupled to a restricted rod 56, which extends in the direction of the height Z. The restricted rod 56 can not rotate relative to the distal portion 55. The upper portion of the restricted rod 56 is inserted through the arm coupling member 22 and is coupled to the guide arm 21. A stem wheel 57 is coupled to an intermediate portion of the restricted rod 56. The intermediate portion is, for example, located below of the arm coupling member 22 and above the auxiliary arm 52. The stem wheel 57 can be rotated about the restricted rod 56. As shown in FIG. 4, a door support mechanism 60 is located between the two pillars 23. The door support mechanism 60 holds the doors 2L, 2R such that outward movement of the lower end portions of the doors 2L , 2R be prevented. The door support mechanism 60 is mechanically coupled to the latch mechanism 40 and the drive mechanism 13 (see Fig. 2) by a latch slide 18 (see Fig. 9), which is coupled to the planetary gear mechanism support. . The door support mechanism 60 is driven by the drive mechanism 13. When the locking mechanism 40 is in the locked state, the door support mechanism 60 restricts a movement of the swing arm mechanisms 20L, 20R and supports doors 2L, 2R. More specifically, in cooperation with the tilting of the locking mechanism 40 from the unlocked state to the locked state driven by the driving mechanism 13, the door support mechanism 60 prevents the outward movement of the parts of the latch. lower end of doors 2L, 2R. The lower end portions of the doors 2L, 2R which are supported by the door support mechanism 60 and the door locking portions 2L, 2R which are locked by the locking mechanism 40 (see Fig. 3) are different from or spaced from each other in the direction of the height Z. The door support mechanism 60 mainly comprises a movable support 61, which is movable in the front-rear direction Y when the support of the planetary gear mechanism rotates, two coupling rods 65L, 65R, which are movable integrally with the movable support 61 in the front-rear direction Y, and two restriction elements 66L, 66R, which are respectively fixed to the coupling rods 65L, 65R and restrict movement of the swing arm mechanisms 20L, 20R. The movable support 61 is located in the middle of the sliding-sliding door opening-closing apparatus 10 (see Fig. 2) in the front-rear direction Y and at an inner side of the support frame 12 ( see Fig. 2) in the direction of the width X. The coupling rod 65L extends from the movable support 61 towards the left side in the front-back direction Y. The coupling rod 65R extends from the support movable 61 toward the right side in the front-rear Y direction. The restriction members 66L, 66R are each attached to a door-opening side portion of the corresponding coupling rod of the coupling rods 65L, 65R with bolts. As shown in FIG. 9, the movable support 61 comprises an upper coupling portion 61A, which extends in the direction of the height Z. The locking slide 18 is coupled to an upper end portion of the upper coupling portion 61A. An inclined portion 61B, which is inclined outward as it extends downward, is in continuity with a lower end portion of the upper coupling portion 61A. A lower coupling portion 61C, which extends outwardly, is in continuity with an outer end of the inclined portion 61B in the direction of the width X.
[0015] A guide member 62, which guides movement of the movable support 61 in the front-back direction Y, is located on a lower portion of the upper coupling portion 61A at an outer side of the upper coupling portion 61A. The guide member 62 comprises a rail 62A, which is coupled to a lower end portion of the support frame 12 (see Fig. 2), and a slider 62B, which is engaged with the rail 62A and is movable by relative to the rail 62A in the Y forward-back direction. The rail 62A extends in the front-back Y direction. A connecting member 62C is coupled to an inner side surface of the slider 62B in the X-width direction. connecting member 620 is attached to the lower portion of the upper coupling portion 61A with bolts. The connecting member 62C extends upwardly and outwardly beyond the slider 62B. A roll 63 is coupled to an upper outer end of the connecting member 62C and is rotatable relative to the connecting member 62C about an axis of rotation extending in the Z-height direction. 2L, 2R (see Fig. 2) are completely closed, the roller 63 is in contact with an outer side surface of a block 15E, which defines a flat surface 15F. Block 15E is attached to an upper surface of the second coupling plate 15B of the door suspension device 15L. A rod attachment member 64, which fixes one end of the door closure side of each of the coupling rods 65L, 65R, is attached to an outer end of the lower coupling portion 610 in the width X direction.
[0016] As shown in FIG. 10, the coupling rod 65R comprises a first rod 65A, which is attached to the rod attachment member 64 (see Fig. 9), a second rod 65B, to which the restriction member 66R is attached, and a rod length adjustment mechanism 650, which couples the first rod 65A and the second rod 65B and can adjust the length of the coupling rod 65R.
[0017] The stem length adjusting mechanism 65C comprises a rod-shaped bolt 65D and two nuts 65E, which are attached to the bolt 65D. A change in the position of the nuts 65E relative to the bolt 650 changes the insertion amount of the bolt 650 in the first rod 65A and in the second rod 65B. Therefore, the length of the coupling rod 65R is adjusted. The second rod 65B is supported by two tubular support members 67. The support members 67 support the second rod 65B at the front and rear of the restriction member 66R. The second rod 65B is inserted through these support members 67. The support members 67 are coupled to a lower surface of the base 11. The structure of the coupling rod 65L and the structure in which the coupling rod 65L is supported by the support members 67 are the same as those of the coupling rod 65R. As shown in FIG. 11, the restriction member 66R is located at an outer side of the coupling rod 65R. The restriction element 66R is hollowed out and opens towards the door closing side. An outer portion of the restriction member 66R includes a flat surface 66A, which extends in the front-back direction Y. The end of the door-closing side of the flat surface 66A is in continuity with an inclined surface 66B which is angled outward in the direction of the width X as it moves away from the flat surface 66A. As shown in FIG. 11, when the doors 2L, 2R (see Fig. 2) are completely closed, the pin wheel 57 is in contact with the flat surface 66A. The structure and operation of the locking mechanism 40 will now be described with reference to FIGS. 12 and 13. It is preferred that the latching mechanism 40 operate when the door 2L, 2R are completely closed and does not function otherwise. As shown in FIG. 12, the locking mechanism 40 comprises a connecting mechanism 41 and two actuating elements 46L, 46R. The linking mechanism 41 can be moved between a folded state shown in FIG. 12 and a straight state shown in FIG. 13. When the link mechanism 41 is moved between the folded state and the right state, the actuating elements 46L, 46R are actuated. The locking mechanism 40 also includes a guide plate 47, which is indicated by the dashed lines in the drawing. The guide plate 47, which is located next to the connecting mechanism 41 and the actuating members 46L, 46R at the inner side in the width direction X, guides movement of the connecting mechanism 41 and the slider. locking 18. The locking slide 18 is inserted into a lower portion of the guide plate 47, which defines a first guide hole 47A which guides movement of the locking slide 18 in the forward-backward direction Y.
[0018] The link mechanism 41 comprises three coupled links 42, 43, 44. The central link 42 is rotatable about a center of rotation CI, which is located in a longitudinally median portion. A protrusion 42A protrudes from the edge of a longitudinally medial portion of the link 42 in a direction separating from the center of rotation C1. The link 43 is coupled to a longitudinally right end of the link 42 and is rotatable relative to the link 42. The link 44 is coupled to a longitudinally left end of the link 42 and is rotatable relative to the link 42. Pressure portions 45A, 45B are attached to the distal ends of the links 43, 44, respectively. The pressure portions 45A, 45B are partially inserted into second guide holes 47B, which are provided for the guide plate 47 and oblong in the front-back direction Y defining the longitudinal direction. The actuating members 46L, 46R are respectively located at positions beside the links 42, 42 in the front-back direction Y. Each of the actuating members 46L, 46R includes a first bias portion 46A, which constrains the portion corresponding one of the pressure portions 45A, 45B, and a second bias portion 46B, which constrains the shaft 15C of the corresponding door suspension device among the door suspension devices 15L, 15R. The actuating elements 46L, 46R can each rotate about a center of rotation C2. A return spring (not shown) is coupled to the outer side surface of each of the actuating members 46L, 46R in the direction of the width X. The return springs apply a force, which recalls the actuating elements 46L, 46R from the position when the locking mechanism 40 is straight, to the position when the locking mechanism 40 is bent, to the actuating members 46L, 46R. An example of the return spring is a coil spring. When the locking mechanism 40 is in the locked state as shown in FIG. 13 and the motor output shaft of the drive mechanism 13 (see Fig. 2) rotates forward, the carrier rotates forwards and the lock slide 18 moves into the first guide hole 47A in an unlocking direction Y1 of the front-rear direction Y. Then, as shown in FIG. 12, when the locking slide 18 pushes the projection 42A of the link 42 in the unlocking direction Y1, the link 42 rotates about the center of rotation C1 in a first direction W1. The rotation of the link 42 rotates the links 43, 44 and separates the pressure portions 45A, 45B from the corresponding actuating members 46L, 46R along the second guide holes 47B in the front-back direction Y. Therefore, the return springs rotate the actuating elements 46L, 46R around the center of rotation C2 in a return direction R1. As a result, the locking mechanism 40 is folded as shown in FIG. 12. At this point, the first constraining portions 46A of the actuating members 46L, 46R do not constrain the shafts 15C of the door hangers 15L, 15R. The locking mechanism 40 is therefore in the unlocked state. When the locking mechanism 40 is in the unlocked state as shown in FIG. 12 and the output shaft of the motor of the drive mechanism 13 rotates rearwards, the support rotates rearwards and the locking slide 18 moves in a locking direction Y2 of the front-rear direction Y. Then, as shown in FIG. 13, when the locking slide 18 pushes a portion coupling the link 42 and the link 44 in the locking direction Y2, the link 42 rotates about the center of rotation C1 in a second direction W2, which is opposite to the first direction W1. The rotation of the link 42 rotates the links 43, 44. Then, the pressure portions 45A, 45B move towards the corresponding actuating elements 46L, 46R in the front-back direction Y and exert a pressure on the elements 46L, 46R actuation in the front-rear direction Y. Therefore, the actuating elements 46L, 46R rotate about the center of rotation C2 in a direction of rotation R2, which is opposite to the return direction R1, against the force return springs. As a result, the locking mechanism 40 becomes straight as shown in FIG. 13. At this time, the second biasing portions 46B of the actuating members 46L, 46R constrain the pressing portions 45A, 45B, and the first biasing portions 46A constrain the shafts 15C of the door hanger devices 15L, 15R. The locking mechanism 40 is therefore in the locked state. The operation and effect of the door support mechanism 60 will now be described with reference to Figs. 14-16. In the description, hereinafter, the "unlocked position" refers to a position of the movable support 61 when the locking mechanism 40 is in the unlocked state, and the "locked position" refers to a position of the mobile support 61 when the locking mechanism 40 is in the locked state. The entire operation of the door support mechanism 60 will now be described.
[0019] As shown in FIG. 14A, when the locking mechanism 40 (see Fig. 12) is in the unlocked state, the restriction members 66L, 66R are located at a non-restriction position where the restriction members 66L, 66R are separated from the restricted rods 56 in the front-rear Y direction and do not restrict a movement of the swing arm mechanisms 20L, 20R. When the locking mechanism 40 is tilted from the unlocked state to the locked state, the locking slide 18 (see Fig. 12) moves from the unlocked position in the locking direction Y2 and the movable support 61 which is coupled to the locking slide 18, moves from the unlocked position in the locking direction Y2. In this case, the coupling rods 65L, 65R move in solidarity with the movable support 61 in the locking direction Y2. Therefore, the restriction elements 66L, 66R, which are coupled to the coupling rods 65L, 65R, move from the non-restriction position in the locking direction Y2. Then, as shown in FIG. 14B, when the locking mechanism 40 is in the locked state, the movable support 61 is in the locking position, and the restriction members 66L, 66R are at a restriction position. The restriction members 66L, 66R therefore constrain the restricted rods 56 in the direction of the width X. The operation of the roller 63, which is coupled to the movable support 61, will now be described. As shown in FIG. 15, when the movable support 61 (see Fig. 14) moves from the unlocked position in the locking direction Y2, the roll 63, which is coupled to the movable support 61, moves in solidarity with the movable support 61 in the direction of locking Y2. Next, the roller 63 contacts the inclined surface 15G of the block 15E of the door suspension device 15L and is guided toward the flat surface 15F. The roller 63 is in contact with the flat surface 15F as it moves in the locking direction Y2. At this time, the rollers 63 roll on the inclined surface 15G and on the flat surface 15F. When the movable support 61 is in the locked position, the roll 63 is in contact with the flat surface 15F, as indicated by the dashed lines in the drawing. The operation of the restriction members 66L, 66R will now be described. As shown in FIG. 16, when the restriction element 66R, which is located at the non-restriction position indicated by the solid lines, moves in the locking direction Y2, the restriction element 66R becomes close to the restricted rod 56 The stem wheel 57, which is coupled to the restricted rod 56, contacts the inclined surface 66B of the restriction member 66R and is guided to the flat surface 66A as the restriction member 66R moves into the locking direction Y2. At this time, the spindle wheel 57 rolls on the inclined surface 66B and the flat surface 66A. When the movable support 61 is in the locked position, the restriction member 66R moves to the restriction position, which is the position of the restriction member 66R indicated by the dashed lines. In this case, the pin wheel 57 is in contact with the planar surface 66A but is separated from a portion of the restriction member 66R which is opposed to the flat surface 66A in the direction of the width X having a spacing between the two in the width X direction. When the restriction member 66R restricts the stalk wheel 57, the restricted stalk 56 is restricted by the restriction member 66R. This restricts rotation of the guide arm 21 and the upper tilting arm 51 (see Fig. 14), which are coupled to the restricted rod 56. A movement of the restriction member 66R in the front-back direction Y is restricted by the movable support 61 and the coupling rod 65R due to the locking mechanism 40. In addition, a restriction of the rotation of the rocking arm 51 restricts a rotation of the pillar 23, which is coupled to the upper rocking arm 51, and the rocking arm lower end 25 (see Fig. 14), which is coupled to the pillar 23. Even when the force exerting pressure on the door 2R (see Fig. 2) outwards is applied to the lower end portion of the 2R door, the lower rocker arm 25 does not rotate. This limits the movement of the lower end portion of the door 2R. Here, the restriction element 66L performs the same operation as the restriction element 66R. Even when the force exerting pressure on the door 2L outwards is applied to the lower end portion of the door 2L, movement of the lower end portion of the door 2L is limited. The tilting-sliding door device 1 of the embodiment has the advantages described below. (1) The tilting-sliding door device 1 comprises the door support mechanism 60, which prevents the outward movement of the lower end portions of the doors 2L, 2R. Even when the doors 2L, 2R receive a high force which exerts pressure on the doors 2L, 2R outwards, the outward movement of the lower end portions of the doors 2L, 2R is prevented. In addition, the formation of a spacing between the side wall of the vehicle 210 and the doors 2L, 2R is limited. The rigidity of the doors 2L, 2R and the locking mechanism 40 need not be improved. (2) The door support mechanism 60 supports the doors 2L, 2R at 5, restricting movement of the lower arm mechanisms 20L, 20R: The door support mechanism 60 can therefore be located on the edge of the side wall of the door. vehicle 210, which is adjacent to the input 211. The door support mechanism 60 does not cause decreases in the open area of the inlet 211, and the entrance 211 of the vehicle side wall can be enlarged. (3) The planar surfaces 66A of the restriction members 66L, 66R of the door support mechanism 60 are each in contact with the stem wheel 57 of the corresponding restricted rod 56 when the restriction members 66L, 66R are located at the Restriction position. When the restriction members 66L, 66R are located at the restriction position, the restricted rods 56 therefore do not move outwardly. This further limits a movement of the swing arm mechanisms 20L, 20R in comparison with the case in which gaps are formed between the planar surfaces 66A of the restriction members 66L, 66R and the stalk wheels 57. Spacing formation between the side wall of the vehicle 210 and the doors 2L, 2R is also limited. (4) The drive mechanism 13 of the tilting-sliding door opening-closing apparatus 10 is located on the upper parts of the doors 2L, 2R. The restriction members 66L, 66R restrict rotation of the upper tilting arms 51 of the swing arm mechanisms 20L, 20R. The drive mechanism 13 and the restriction members 66L, 66R can therefore be located close to each other in comparison with a structure in which the restriction members 66L, 66R restrict rotation of lower portions of the swing arm mechanisms 20L. , 20R, for example, the lower tilting arms 25. This allows the driving force to be easily transmitted from the drive mechanism 13 to the restriction members 66L, 66R. (5) The door support mechanism 60 comprises the movable support 61 and the coupling rods 65L, 65R, which couple the drive mechanism 13 and the locking mechanism 40 to the restriction members 66L, 66R. This stabilizes the operation of the door support mechanism 60 in comparison with a structure in which the drive mechanism 13 and the locking mechanism 40 are coupled to the restriction members 66L, 66R, for example, by cables. (6) The coupling rods 65L, 65R each include the stem length adjustment mechanism 65C. The position of the restriction members 66L, 66R is therefore adjustable relative to the restricted rods 56 in the forward-backward direction Y by adjusting the length of the coupling rods 65L, 65R. This allows the position of the restriction members 66L, 66R to be easily changed even after assembly of the swivel-slide door opening-closing apparatus 10 so that movement in the width direction X is further suitably limited in the lower end portions of the doors 2L, 2R. (7) The support members 67 are adapted to support the coupling rods 65L, 65R and to prevent outward deformation of the coupling rods 65L, 65R. The outward deformation of the coupling rods 65L, 65R is therefore limited. This prevents movement of the restriction members 66L, 66R relative to the swing arm mechanisms 20L, 20R. The restriction members 66L, 66R thus appropriately maintain the function of restricting movement of the swing arm mechanisms 20L, 20R. (8) The support members 67 support the coupling rods 65L, 65R at the front and rear of the restriction members 66L, 66R. This further prevents deformation of the coupling rods 65L, 65R in the X-width direction when a high force is applied from the swing arm mechanisms 20L, 20R to the restriction members 66L, 66R. (9) The guide member 62, which guides movement of the movable support 61 in the forward-backward direction Y, is coupled to the movable support 61. When a force is applied to the doors 2L, 2R, the guide member 62 therefore receives the force. This prevents the force applied to the doors 2L, 2R from being transmitted to the locking mechanism 40. The locking mechanism 40 is thus kept in the locked state stably. In addition, the guide member 62 fluidly displaces the movable support 61 in the fore-and-aft direction Y. The locking mechanism 40 is thus easily tilted to the locked state and to the unlocked state. This reduces the load especially when an operator switches the state manually. (10) Restrictors 66L, 66R and coupling rods 65L, 65R correspond to swing arm mechanisms 20L 20R, respectively. The restriction elements 66L, 66R can therefore be moved by moving the coupling rods 65L, 65R. In particular, since the coupling rods 65L, 65R are coupled to the movable support 61, the coupling rods 65L, 65R can be moved integrally by moving the movable support 61. This simplifies the task of opening and closing manually. gates 2L, 2R in comparison to the case in which an operator moves the restriction elements of 66L, 66R individually. (11) The restriction members 66L, 66R restrict rotation of the upper tilting arms 51 by using the restricted rods 56. The force required to restrict movement of the tilting arm mechanisms 20L, 20R is therefore decreased in comparison with the case in which the door support mechanism 60 applies a force directly to the pillars 23. This eliminates the need to increase the rigidity of the door support mechanism 60. The door support mechanism 60 can therefore be reduced in size. In addition, a rotation of the lower rocker arms 25 is restricted in addition to a rotation of the upper rocker arms 51. This prevents the formation of spacings between the lower end portions of the gates 2L, 2R and the vehicle sidewall 210. (12) When the locking mechanism 40 locks the doors, the roller 27 of each lower tilting arm 25 exerts pressure on the pressed portion 34 toward the door closing side. This limits a movement of the lower end portions of the doors 2L, 2R towards the door opening side. In particular, the door support mechanism 60 prevents rotation of the lower tilt arms 25 when the doors are closed. The roller 27 thus exerts a steady pressure on the pressed portion 34. (13) The lower slide rails 30L, 30R support the rollers 26 of the lower rocker arms 25 in the width X direction. Each press portion 34 includes the contact surface 34A, which is in contact with the roller 27 of the corresponding lower tilting arm 25 and is inclined inwards and in the direction of the width X as it extends into the door closing side. When the doors 2L, 2R move in the front-rear direction Y, the lower sliding rails 30L, 30R thus move fluidly with respect to the rollers 26. Moreover, when the doors 2L, 2R are completely closed, the lower roller 26 of each swinging arm 25 receives an outward component of the force acting from roller 27 to pressed portion 34. This limits outward movement of the lower end portions of doors 2L, 2R . (14) Since each restricted rod 56 extends in the direction of the height Z, the position in which each of the restriction members 66L, 66R is in contact with the restricted rod 56 can be selected within a range of the length. of the restricted rod 56. This increases the degree of freedom for the design of the position in which the restriction elements 66L, 66R are located in the direction of the height Z. (15) When the restriction elements 66L, 66R are moving from the non-restriction position to the restriction position, the pinwheels 57 are in contact with the restriction members 66L, 66R as they rotate. This reduces a frictional force between the restriction members 66L, 66R and the shank wheels 57. The restriction members 66L, 66R thus come into contact with and separate the restricted rods 56 in a fluid manner. (16) Each restricted rod 56 is coupled by the guide arm 21 and the upper rocker arm 51. This prevents deformation of the restricted rod 56 when a force is applied to the restricted rod 56 in the direction of the width X and in the forward-backward direction Y. A movement of the upper tilting arms 51 of the tilting arm mechanisms 20L, 20R can thus be stably limited. (17) Each restricted rod 56 is rotatably coupled to the upper tilting arm 51 and is coupled to the auxiliary arm 52, which adjusts the position relative to the guide arm 21. Even when errors in the rotational positions of the upper tilting arms 51 and guide arms 21 occur, such errors can be compensated by rotating the auxiliary arms 52 relative to the upper tilting arms 51 during assembly of the rocker arm mechanisms 20L, 20R. (18) The arm length adjustment mechanism 53 of each auxiliary arm 52 allows adjustment in the position of the restricted rod 56 relative to the corresponding one of the restriction elements 66L, 66R by adjusting the length of the auxiliary arm 52. Even after the sliding-sliding door opening-closing apparatus 10 is assembled, the position of the restricted rods 56 can therefore be easily modified so that a movement of the lower end portions of the doors 2L, 2R is suitably limited in the direction of the width X. (19) The restriction members 66L, 66R each comprise the flat surface 66A. Even when a force which presses the restriction elements 66L, 66R outwards is applied from restricted rods 56 to the restriction elements 66L, 66R, the formation of a component of the force, which acts in the front-back Y direction, is limited. This decreases the situations in which the restriction elements 66L, 66R are moved to the unrestricted position due to the force applied to the doors 2L, 2R or the like in the locked state. (20) The restriction elements 66L, 66R each comprise the inclined surface 66B. As the restriction members 66L, 66R move from the non-restriction position to the restriction position, the inclined surface 66B of each of the restriction members 66L, 66R contacts the stem wheel 57 of the restricted rod 56 The stem wheel 57 and the restricted rod 56 are thus displaced along the inclined surface 66B and are directed to the flat surface 66A of a corresponding one of the restriction members 66L, 66R. This moves the restricted rod 56 and the rod wheel 57 to the flat surface 66A in a fluid manner. (21) The drive mechanism 13 functions as a drive source for moving the gates 2L, 2R and also as a drive source for tilting the locking mechanism 40 between the locked state and the unlocked state. The driving force (for example, a motor output) of the drive mechanism 13 for moving the doors 2L, 2R is greater than the driving force which is output by a drive source dedicated to a locking mechanism . Such high driving force is used to drive the door support mechanism 60. An outward movement of the lower end portions of the doors 2L, 2R is thus more surely limited. In addition, the number of drive sources of the tilting-sliding door opening-closing apparatus 10 can be reduced in comparison with the case in which the drive source dedicated to the locking mechanism is provided. (22) When the doors 2L, 2R are completely closed, the roller 63, which is coupled to the connecting member 62C of the guide member 62, is in contact with the flat surface 15F, which is defined by the outer surface of the block 15E of the door suspension device 15L. This limits an outward movement of the door suspension device 15L. Therefore, an outward movement of the upper parts of the door 2L and the door 2R, which moves in accordance with the door 2L, can be limited. In addition, as the movable support 61 moves in the forward-backward direction Y, the roll 63 is in contact with the planar surface 15F as it rotates. This reduces the frictional force between the roller 63 and the block 15E. The roller 63 thus comes into contact with and separates from the block 15E fluidly. (23) Block 15E includes inclined surface 15G. As the movable support 61 moves from the unlocked position to the locked position, the roll 63 contacts the inclined surface 15G. The roll 63 is thus moved along the inclined surface 15G and is guided towards the flat surface 15F of the block 15E. This moves the roll 63 to the flat surface 15F in a fluid manner. It should be obvious to those skilled in the art that the present invention can be embodied in many other specific forms without departing from the scope of the invention. In particular, it should be understood that the present invention may be embodied in the following forms. The door support mechanism 60 may have any structure to support the door 2L, 2R and may be modified as follows. Fig. 17 shows a door support mechanism 100, which comprises a restriction rod 101 instead of the restriction element 66R. The door support mechanism 100 supports a lower door portion, which is located at a position lower than that of a portion securing the door hanger 15R (see Fig. 2) and the door 2R, with the rod. The restriction rod 101 is coupled to the coupling rod 65R and extends downwardly from the coupling rod 65R. The upper end portion of the door 2R comprises a slot 2A, which opens upwardly and inwardly in the direction of the width X, and a restricted wall 2B, which is formed on one end of the side for closing the door of the slot 2A in the forward-backward direction Y. The restricted wall 2B is formed on an inner end of the door 2R in the direction of the width X. When it is located at a non-restricted position , which is indicated by the solid lines, the restriction rod 101 does not limit an outward movement of the door 2R. When the restriction rod 101 is located at a restriction position, which is indicated by the dashed lines, the restriction rod 101 and the restricted wall 2B overlap in the direction of the width X. When the door 2R receives a force acting to move the door 2R outwardly, the restriction rod 101 is in contact with the restricted wall 2B and supports the door 2R. This limits an outward movement of the door 2R. In addition, the door support mechanism 100 includes a restriction rod 101 instead of the restriction element 66L. In the same way as the door 2R, the door 2L comprises a slot 2A and a restricted wall 2B. An outward movement of the door 2L is therefore limited in the same way as for the door 2R. Fig. 18 shows a door support mechanism 110, which includes a cam 111 instead of the restriction member 66R. The door support mechanism 110 supports a lower door portion, which is located at a position lower than that of a portion securing the door suspension device 15R (see Fig. 2) and the door 2R, with the cam 111 The circumference of the cam 111 includes a gear 112, which is engaged with a rack gear 121 formed on one end of the door opening side of a coupling rod 120. The cam 111 is rotatably coupled to a rotational shaft 113, which is attached to the side wall of the vehicle 210 (see Fig. 1). In addition, the upper end portion of the door 2R is provided with a receptacle 2C, which opens upwards. When located at a non-restriction position, which is indicated by the solid line, the cam 111 is not located in the receptacle 2C. An outward movement of the door 2R is not limited. As the cam 111 moves in a direction indicated by the white arrow in the drawing, the rack gear 121 pushes the gear 112. This rotates the cam 111 in a direction indicated by the bold arrow. Therefore, the cam 111 is located at a restriction position, which is indicated by the dashed line. In this case, the cam 111 is located in the receptacle 2C of the door 2R. When the door 2R receives a force acting to move the door 2R outwards, the cam 111 thus comes into contact with a wall defining the receptacle 2C of the door 2R and supports the door 2R. This limits an outward movement of the door 2R. In addition, the door support mechanism 110 includes a cam 111 and a coupling rod 120 in place of the coupling rod 65L and the restriction member 66L. An outward movement of the door 2L is therefore limited in the same way as for the door 2R. Fig. 19A shows a door support mechanism 130 comprising two cables 131L, 131R coupled to the movable support 61, two pulleys 132L, 132R respectively supporting the cables 131L, 131R, and 133L, 133R pins coupled to ends of the cables 131L, 131R. The doors 2L, 2R are each provided with a 2D receptacle, which opens towards the door closing side and is located in a middle part, with respect to the direction of the height Z, of the end of the side of the door. door opening of the corresponding door among the doors 2L, 2R. Each of the pins 133L, 133R is inserted into the 2D receptacle. As shown in FIG. 19B, when the movable support 61 is in the unlocked position, the pin 133L is located in an upper end portion of the 2D receptacle of the door 2L, which functions as a non-restriction position. The upper end portion of the 2D receptacle of the door 2L opens inwards in the direction of the width X. The pin 133L therefore does not support limiting an outward movement of the door 2L. As shown in FIG. 19C, when the movable support 61 is in the unlocked position, the pin 133R is located in a lower end portion of the 2D receptacle of the door 2R, which functions as a non-restriction position. The lower end portion of the 2D receptacle of the door 2R opens inwards in the direction of the width X. The pin 133R therefore does not support limiting an outward movement of the door 2R.
[0020] As shown in FIG. 19A, when the movable support 61 moves from the unlocked position in the locking direction Y2, the cable 131L moves along the pulley 132R in a direction indicated by the white arrows, and the pin 133L moves towards the low. In addition, the cable 131R moves along the pulley 132R in the direction indicated by the white arrows, and the pin 133R moves upwards.
[0021] Then, as shown in FIG. 19B, when the movable support 61 is in the locked position, the pin 133L is located in a lower end portion of the 2D receptacle of the door 2L, which functions as a restriction position, and is opposed to a restricted wall 2E formed on a lower side of the receptacle 20 in the direction of the width X. In addition, as shown in FIG. 19C, the pin 133R is located in an upper end portion of the 2D receptacle of the gate 2R, which functions as a restriction position, and is opposed to a restricted wall 2E formed of an upper side of the 2D receptacle in the direction of the width X. When the doors 2L, 2R receive a force acting to move the doors 2L, 2R outwards, the pins 133L, 133R thus come into contact with the restricted walls 2E and limit an outward movement doors 2L, 2R. Fig. 20A shows a door support mechanism 140, which includes support shafts 141L, 141R and engaging claws 142L, 142R in place of the pins 133L, 133R of the door support mechanism 130. The support shafts 141L , 141R are attached to the side wall of the vehicle 210 (see Fig. 1) and extend inward in the direction of the width X from the side wall of the vehicle 210. The engagement claws 142L, 142R are rotatably coupled to the support shafts 141L, 141R. In addition, the doors 2L, 2R are each provided with a receptacle 2F, which can receive a portion of a corresponding engagement claw among the engagement claws 142L, 142R. Two opposite sides of each receptacle 2F in the direction of width X are closed. A pin 143L, which extends in the width direction X, is coupled to the gate 2L in a lower portion of the 2F receptacle of the gate 2L. In addition, a pin 143R, which extends in the direction of the width X, is coupled to the door 2R in an upper part of the receptacle 2F of the door 2R.
[0022] As shown in FIG. 20A, when the movable support 61 moves from the unlocked position in the locking direction Y2, the cable 131L moves along the pulley 132L in a direction indicated by the white arrows, and a distal end of the claw of 142L engagement moves down as it rotates around 141L support shaft. In contrast, a distal end of the engaging claw 142R moves upward as it rotates around the support shaft 141R. Then, as shown in FIG. 20B, when the movable support 61 is in the locked position, the engaging claw 142L is located in the lower end portion of the 2F receptacle of the door 2L, which functions as a restriction position, and is engaged with pin 143L. As shown in FIG. 20C the engagement claw 142R is located in the upper end portion of the 2F receptacle of the door 2R, which functions as a restriction position, and is engaged with the pin 143R. When the doors 2L-2R receive a force acting to move the doors 2L, 2R outwards, the pins 133L, 133R thus come into contact with the restricted walls 2E and support the doors 2L, 2R.
[0023] Fig. 21 shows a door support mechanism 150, which comprises a first cable 151, which is coupled to the movable support 61, and two first pulleys 152L, 152R, which are separated in the front-rear direction Y and support the first cable 151. The first cable 151 is wound around the first pulleys 152L, 152R to be annular. The first pulleys 152L, 152R are coupled to the second pulleys 153L, 153R, which are located at an outer side of the first pulleys 152L, 152R and rotate integrally with the first pulleys 152L, 152R. Second cables 154L, 154R are wrapped around the second pulleys 153L, 153R, respectively. Pins 155L, 155R are coupled to the distal ends of the second leads 154L, 154R, respectively. The pins 155L, 155R are located above the upper tilting arms 51 of the tilting arm mechanisms 20L, 20R and extend in the Z-direction of height. The upper tilting arms 51 are each provided with a through-hole 51A, which can receive the corresponding pin among the pins 155L, 155R. The pins 155L, 155R are located above the upper tilting arms 51, which function as a non-restriction position. In particular, when the doors 2L, 2R are completely closed, the pins 155L, 155R are arranged to overlap the through holes 51A of the upper tilting arms 51 in the direction of the height Z. The pins 155L, 155R are partially inserted into cylinders 156L, 156R, respectively, which are attached to the side wall of the vehicle 210 (see Fig. 1). As the movable support 61 moves from the unlocked position in the locking direction Y2, movement of the first cable 151 rotates the first pulleys 152L, 152R and the second pulleys 153L, 153R. As a result, as the second cables 154L, 154R move downward, the pins 155L, 155R move downward. Then, when the movable support 61 is in the locked position, the pins 155L, 155R are inserted into the through holes 51A of the upper tilting arms 51, i.e., are located at the restriction position. Even when the doors 2L, 2R receive a force acting to move the doors 2L, 2R outwardly, the pins 155L, 155R, which are supported by the cylinders 156L, 156R, therefore restrict a rotation of the upper tilting arms 51. This limits outward movement of doors 2L, 2R. Fig. 22 shows a door support mechanism 160, which is configured to restrict rotation of the abutment 23 of the tilt arm mechanism 20R, while the door support mechanism 150 restricts rotation of the upper tilting arms 51. The end surface upper pillar 23 is provided with an adjustment hole 23A, which is recessed downwards. The adjustment hole 23A is D-shaped. In addition, the pin 155R is located above the upper end surface of the pillar 23 and is D-shaped. Although not shown in FIG. 22, the pin 155L and the pillar 23 of the swing arm mechanism 20L have the same shape as the pin 155R and the pillar 23 of the swing arm mechanism 20R. When the movable support 61 (see Fig. 21) is in the locked position, the spindle 155R is fitted into the adjustment hole 23A. This restricts rotation of the pillar 23 and limits outward movement of the door 2R.
[0024] Fig. 23 shows a door support mechanism 170 comprising a cable 171, which is coupled to the movable support 61, and two pulleys 172L, 172R, which are separated in the front-rear direction Y and support the cable 171. The cable 171 is wound around pulleys 172L, 172R to be annular. The restriction members 66L, 66R are coupled to a lower portion of the annular cable 171. The restriction members 66L, 66R move in solidarity with the cable 171. The position of the restriction members 66L, 66R relative to the restricted rods 56 in the front-rear direction Y is opposed to the position of the restriction members 66L, 66R of the above embodiment with respect to the restricted rods 56 in the front-rear direction Y. The door support mechanisms 100, 110, which are shown in Figs. 17 and 18, can be located in any position. For example, the door support mechanisms 100, 110 are located on the lower end portions of the doors 2L, 2R or on the side walls of the door opening side of the doors 2L, 2R. The door support mechanisms 130, 140, which are shown in FIGS. 19 and 20, can be modified as follows. In FIG. 19, the 2D receptacles of the doors 2L, 2R and the pins 133L, 133R of the door support mechanism 130 are located in the lower end portions of the doors 2L, 2R. In FIG. 20, the receptacles 2F of the doors 2L, 2R and the pins 143L, 143R of the door support mechanism 140 are located in the lower end portions of the doors 2L, 2R. The doors 2L, 2R shown in FIGS. 17 to 20 can be modified as follows. In FIG. 17, the slots 2A are omitted from the doors 2L, 2R, and the restricted walls 2B extend from the side walls of the door opening side of the doors 2L, 2R to the corresponding door opening sides. In FIG. 18, the receptacles 2C are omitted from the doors 2L, 2R, and restricted walls extend from the side walls of the door opening side of the doors 2L, 2R to the corresponding door opening sides. In this case, when in the restricted position, the cams 111 are opposed to the restricted walls in the direction of the width X. In FIGS. 19 and 20, the receptacles 2C, 2D are omitted from the doors 2L, 2R, and restricted walls extend from the side walls of the door opening side of the doors 2L, 2R to the corresponding door opening sides . The modified examples of FIGS. 17 to 20 do not include swing arm mechanisms 20L, 20R. The door support mechanism 150, which is shown in FIG. 21, can be modified as follows. The door support mechanism 150 restricts rotation of the lower rocker arms 25 with the pins 155L, 155R instead of restricting rotation of the upper rocker arms 51. In this case, the second wires 154L, 154R extend to lower portions. pillars 23, and the pins 155L, 155R are located at the lower portions of the pillars 23 above the lower tilting arms 25. The number of rod length adjustment mechanisms 65C can be changed. Alternatively, the stem length adjustment mechanism 65C may be omitted. The stem length adjustment mechanism 65C may be configured to change the length of a versatile expandable rod assembly. Such an adjustment mechanism may include, for example, a screw which is secured from outside a second tubular shaft when a first rod is inserted into the second rod. The screw fixes the first rod and the second rod when the relative position of the first rod and the second rod is adjusted in the longitudinal direction. For example, a fastener nut that attaches an expandable multitubular rod assembly to the adjusted length can be used. The arm length adjustment mechanism 53 of the auxiliary arm 52 can be modified in the same manner as the rod length adjustment mechanism 65C. The door support mechanism 60 may comprise a single coupling rod instead of the coupling rods 65L, 65R. The restriction elements 66L, 66R are coupled to the single coupling rod.
[0025] The door support mechanism 60 can exclude at least one of the rollers 63, the connecting member 62C, and the guide member 62. The door support mechanism 60 excludes the roll 63, the block 15E is omitted from the second coupling plate 15B. When the door support mechanism 60 excludes the connection member 62C, the roll 63 is rotatably coupled to the upper coupling portion 61A of the movable support 61. The movable support 61 of the door support mechanism 60 can be connected. directly to the support. More specifically, a modified example of the door support mechanism 60 does not include the locking slider 18. In this case, the movable support 61 includes a protrusion functioning as the locking slider 18.
[0026] The door support mechanism 60 may have any structure in which the movable support 61 and the restriction members 66L, 66R are coupled. For example, the movable support 61 and the restriction members 66L, 66R may be coupled by a gear train or a cable in place of the coupling rods 65L, 65R.
[0027] The restricted rod 56 of each coupling mechanism 50 does not need to be coupled to the guide arm 21. Each coupling mechanism 50 does not need to include the rod wheel 57. In this case, when the Restricted rods 56 are in contact with the restriction members 66L, 66R, a rotation of the upper rocker arms 51 is restricted.
[0028] Each coupling mechanism 50 does not need to include the auxiliary arm 52. In this case, the restricted rod 56 is coupled to the upper rocker arm 51. The auxiliary arm 52 of each coupling mechanism 50 can be coupled to the rocker arm upper 51 in a non-rotating manner. The restricted rod 56 of each coupling mechanism 50 may be coupled to the auxiliary arm 52 and rotatable relative to the auxiliary arm 52 about the axis of rotation extending in the direction of the height Z. In this case, the wheel rod 57 can be omitted. The auxiliary arm 52 of each coupling mechanism 50 can be coupled to the guide arm 21. In this case, the restricted rod 56 is coupled to the auxiliary arm 52 and the upper tilting arm 51. The number of arm length adjustment mechanisms 53 can be changed. Alternatively, the arm lock adjustment mechanism 53 may be omitted. In this case, in the auxiliary arm 52, the base portion 54 and the distal portion 55 are coupled to each other.
[0029] The elements which restrict rotation of the upper tilting arms 51 when in contact with the restriction members 66L, 66R do not need to be rod-shaped such as the restricted rod 56 and may be block-shaped or to be spherical. The shape of the elements that restrict rotation of the upper tilting arms 51 may be other than rod-shaped as long as the rotation of the upper tilting arms 51 is restricted when in contact with the restriction members 66L, 66R. The shank wheels 57 need not be in contact with the flat surfaces 66A when the restriction members 66L, 66R are moving in the locking direction Y2.
[0030] The guide member may be attached to the base 11 and may include a rail, which extends in the forward-backward direction Y, and a wheel that rolls in the rail. The wheel may be coupled to the upper coupling portion 61A of the movable support 61 and rotatable relative to the upper coupling portion 61A. The guide member may be attached to the base 11 and may include a tubular ring, which extends in the forward-backward direction Y, and a pin, which is inserted into the ring and movable relative to the ring in the front-rear direction Y. The spindle comprises a front end and a rear end, which protrude respectively forward and backward from the ring. The two opposite ends of the pin are coupled to the upper coupling portion 61A of the movable support 61.
[0031] The guide member may guide the coupling rods 65L, 65R or the restriction members 66L, 66R in the forward-backward direction Y instead of guiding the movable support 61. As shown in FIG. 24, the restriction members 66L, 66R can each be L-shaped. The restriction members 66L, 66R each comprise the flat surface 66A and the inclined surface 66B in the same manner as the restriction elements 66L, 66R of the realization above. The restriction elements 66L, 66R may each comprise a tetragonal component. The restriction members 66L, 66R restrict rotation of the upper rocking arms 51 of the rocker arm mechanisms 20L, 20R when in contact with the restricted rods 56 in the front-back direction Y. In the structure in which the elements of the Restriction 66L, 66R restricts rotation of swing arm mechanisms 20L, 20R, restriction members 66L, 66R each may be projecting, and upper swing arms 51 of swing arm mechanisms 20L, 20R each may include a recessed moving portion . The restriction elements 66L, 66R can be adjusted in the recessed moving parts. For example, when located at the restriction position, the restriction members 66L, 66R above, each of which comprises the tetragonal piece, are fitted into the recessed portions formed in the upper tilting arms 51 of the rocking arm mechanisms. 20L, 20R. In a modified example, at least one of the planar surface 66A and the inclined surface 66B is omitted from each of the restriction elements 66L, 66R. The inclined surface 66B of each of the restriction members 66L, 66R may have any angle of inclination with respect to the front-back direction Y and any size in the front-to-back direction. More specifically, in this modified example, the inclination angle of the inclined surface 66B of this modified example may be greater than or less than the inclination angle of the inclined surface 66B of the above embodiment with respect to the front-back direction Y. The size, in the front-rear Y direction, of the inclined surface 66B of this modified example may be greater or smaller than that of the inclined surface 66B of the above embodiment. The flat surface 66A of each of the restriction members 66L, 66R can be any size in the front-back direction Y. More specifically, the size, in the front-back direction Y, of the flat surface 66A can be greater or smaller to that of the flat surface 66A of the above embodiment. The restriction members 66L, 66R may each include an inclined portion or a curved portion in place of the flat surface 66A.
[0032] The restriction members 66L, 66R can restrict rotation of the swing arm mechanisms 20L, 20R by being in direct contact with at least one of the guide arms 21, the upper swing arms 51, the auxiliary arms 52, the pillars 23, and the lower tilting arms 25. Restrictors 66L, 66R only need to restrict movement of tilt arm mechanisms 20L, 20R when in contact with moving parts of tilt arm mechanisms 20L, 20R. The number of support members 67 can be changed to three or less or five or more. The support members 67 may be attached directly to the vehicle sidewall 210 or attached to an element other than the base 11 and attached to the sidewall of the vehicle 210.
[0033] The support members 67 may be arranged to support each coupling rod 65L (65R) at only one of the front and rear of the restriction member 66L (66R). As shown in FIG. 25, the support member 67 may comprise a support portion 67A, which has a recessed curved surface and supports one of the coupling rods 65L, 65R from the outer side. Alternatively, the support member 67 may comprise a flat surface, which extends in the front-back direction Y and in the direction of the height Z and supports one of the coupling rods 65L, 65R from the side outside. The support member 67 may be other than tubular as long as the support member 67 is configured to support the coupling rods 65L, 65R from the outer side. In addition, the support members 67 may be of different shape from each other. The support portion 67A of the support member 67 of FIG. 25 can open up or down. The direction in which the support portion 67A opens is not limited as long as one of the coupling rods 65L, 65R can be supported from the outer side. Tilting arm mechanisms may guide movement of the doors 2L, 2R using a gear train or link instead of guiding the guide arms 21 and the lower tilting arms 25. The upper tilting arms 51 and the lower tilting arms 25 The tilt arm mechanisms do not need to include the lower tilting arms 25. In this case, the lower slide rails 30L, 30R, which are coupled to the gates 2L, 2R, are omitted. The rocker arm mechanisms need not include the upper rocker arms 51. In this case, the gate support mechanism 60 is configured to restrict rotation of the lower rocker arms 25 or pillars 23.
[0034] The tilting arm mechanisms may have a height which is approximately half that of the doors 2L, 2R in the Z-height direction. In this case, the upper tilting arms 51 are located at positions that correspond to mid-portions of the doors 2L, 2R in the direction of the height Z. The pillars 23 have a length from the lower parts of the doors 2L, 2R to the middle parts of the doors 2L, 2R in the direction of the height Z. The guide arm 21 of each tilting arm mechanism may be coupled to the upper end portion of the abutment 23. The number of guide arms 21 may be varied into five or more or three or less. At least one of the pressed portions 34, which are coupled to the lower slide rails 30L, 30R, may be omitted. In this case, the roller 27 is omitted from the lower rocker arm 25 which corresponds to the pressed portion 34.
