    15 20 25 30 35 2 elevator applications, for example elevators of the type where the locking door locking mechanism is intended to be released by the action of a ramp extendable from an elevator car when the elevator car is on the current ground plane or by the effect of a follower mechanism provided with a cam roller.
    It should be noted that the term "door" in this context refers to all types of doors, gates or similar opening elements at a ground floor, ie simple swing doors, double swing doors, vertical sliding doors and horizontal sliding doors. as used herein, is generally meant all types of means of transport for persons or goods between floors of buildings, ie also work platforms, transport platforms or the like.
    These objects of the invention are achieved by an interlocking mechanism for a floor plan door which exhibits the features and characteristics stated in claim 1.
    Further features and advantages of the invention will be apparent from the subclaims.
    In the following, a more detailed description will be given of a preferred embodiment of the invention. It should be noted that for the sake of clarity, only the details necessary for understanding the principles of the invention are described and shown in the drawings. Furthermore, for the sake of clarity, certain components are omitted in some of the drawings.
    The accompanying drawings show an interlocking mechanism according to the invention applied to ground floor doors at an elevator and with reference to the drawings, in which; Figs. 1 and 2 show in perspective views with partially broken away details parts included in an interlocking mechanism according to the invention, Figs. 3 and 4 show in perspective views with partially broken away parts, of a locking member included in the interlocking mechanism in alternative embodiments, Figs. 5 and 6 show in perspective views with partially broken away parts a portion of a door lock included in the interlocking mechanism according to the invention when used in combination with a revolving door, and fi g. Fig. 7 shows in a perspective view with broken away parts the door lock shown in Figs. 5 and 6 when used in combination with a sliding door.
    An interlocking mechanism of the present kind is intended to be used with a floor plan door which has a door lock which is resettable in a locked locking position in which it engages with a closing element arranged to the door. How the door itself is constructed or what type of door it is at the ground plane has no significance for the invention as such, so the door itself is not described in more detail. Among the many advantages of the interlocking mechanism according to the invention, however, it should be pointed out that it has great flexibility and is directly applicable to a number of known door constructions without the need for modifications, which will also appear from the following description. The units described below are made as lightweight constructions of preferably laser cut and substantially flat sheet metal pieces.
    The interlocking mechanism is described arranged in elevators in two alternative embodiments, in the example shown in Fig. 3 the interlocking mechanism being arranged on a locking mechanism.......................................... ground plane where an elevator car is provided with a ramp which can be folded down towards the ground plane, which ramp in the figure is only shown indicated by dotted line contours. In the example shown in Fig. 4, the interlocking mechanism is applied to a ground plane where an elevator car equipped with a control curve cooperates with a follower, here too the control curve is only indicated by dotted lines. Since both the ramp arranged on the elevator car and the cam curve follower mechanism for elevators where the cam curve is intended to pass past the mechanism are as such already well known, these will therefore neither be described in more detail nor shown in more detail in the drawings, other than sketchy with dotted contour lines. Figs. 1 and 2 show a locking mechanism 1 for a floor plan door 2 arranged on a fixedly mounted floor plan part, the floor door being shown only as part of a front vertical free side of said door intended for co-operation with a door post 3. It should be understood that the door 2 the opposite vertical side at which the door is pivotable about a vertical axis is not shown, as the design of this part is of secondary importance to the invention. The door post 3 is made of sheet metal elements which are bent into a U-profile-shaped box 4 which can be closed by means of a lid, not shown in the figures, but also U-profile-shaped lid so that the U-profile-shaped elements together form a tubular post-like unit.
    The interlocking mechanism 1 essentially consists of a combination of a door lock 6 accommodated in the post 3 which is adjustable in a interlocked locking position in which it engages with a closing element 7 arranged to the door 2. By means of a control lever 8 included in the mechanism, the mechanism can be adjusted and out of the locked position.
    Referring to Figs. 1 and 4, the interlocking mechanism 1 includes a number of locking units connected in series with each other by means of the control lever 8 which can be switched to interlocking position, a first of which comprises a rotary latch 10 which in interlocked position locks the door lock 6 when the locking element 7 is engaged in the lock and the door 2 is closed but conversely also the control lever 8 locks against switching to the locking position if the door is not properly closed, a second locking unit comprises a control lever lock 11 which locks the control lever 8 against switching from the locking position when an elevator car is in motion or beyond a stop and a third locking unit comprises a sensing unit 12 which cuts off the power to the drive motors of the elevator if the interlock should not be set correctly in its normal interlocking position. The control lever lock 11 can be designed for its function in a number of different ways, but in the embodiment described herein comprises a counter surface 13 for a locking lug 15 included in a locking mechanism 14, which locking mechanism is arranged for co-operation with an elevator car and designed so that the locking lug 15 tends to go in blocking engagement with the counter surface 13 when an elevator car is in motion or beyond a ground plane. As will become clearer upon closer study of Figs. 3 and 4 in particular and the following description, it should be understood that the purpose of the locking mechanism 14 is to block the locking mechanism 14 from locking mechanism 14. the control lever 8 against adjustment in one direction from the interlock position as long as the elevator car is in a place other than the current ground plane. The term "coupled" in the following refers to units that are connected to each other for interaction as a common switch to interlock mode.
    As mentioned above, the door lock 6 is accommodated in the U-profile-shaped drawer 4 and is by cooperation between pin 16 and heel 17 fixed in position between the opposite elongate side ends of the drawer and the back piece or bottom. The door lock 6 can also, if appropriate, be fixed in place by welding. The U-profile-shaped drawer 4 is terminated at its upper and lower end ends, respectively, by a plate 18, 18 'which fixed at the ends of the drawer serves as a lid and foot, respectively, for the post 3 where said foot plate is intended to be anchored in the standing plane with the post extending vertically upwards.
    Connected to the control lever 8 is an adjusting rod 19 which extends vertically through the post 3 and has an upper end extending through an opening 20 in the upper end end 18 of the post, said end being provided with a pull handle 21, and the adjusting rod has a lower end in which spring 22 is arranged so as to act as a return on the adjusting rod in a downward direction towards the normal locking position. The sensing unit 12 comprises a switch unit 23 which switches off the power to the drive motors of the lift when the control lever 8 is moved out of its normal locking position. The switch unit 23 comprises an annular cam 24 which the enclosing adjusting rod 19 is displaceable along it and via a adjusting screw 25 can be fixed in certain positions along the adjusting rod. The cam 24 is arranged for co-operation with an electric switch 26 accommodated in the post 3 and thus stationary, which monitors the position of the adjusting rod and switches off the power to the drive motors of the lift when the control lever 8 is moved out of its normal locking position. The switch unit 23 is accommodated in the U-profile-shaped box 4 and is fastened by means of transverse screws 27, extending through mounting heels 28 arranged in opposite elongate ends of the U-profile-shaped box. Thus, two of the locking units 10, 11, 12 included in the interlocking mechanism are adjustable relative to each other in the direction of the control lever 8 and the adjustment of the adjusting rod 19 connected thereto vertically down towards the locking position, namely the rotary lock 10 and the third sensing lock unit 12.
    In Figs. 5 and 6, the door lock 6 included in the present interlocking mechanism is shown in more detail and consists in its basic construction essentially of a first and second end plate 35, 35 'arranged transversely in the post 3 at a mutual distance from each other where one end plate 35 is located above the second 35 ', a pivot case 36, 36' belonging to the respective end plates 35, 35 'which are pivotally mounted around a vertical shaft pin 37 common to them, said end plates 35, 35' each having an insertion mouth 38, 38 'for receiving above-mentioned closing element 7 located on the front vertical free side of the door 2. Furthermore, each pivot 36, 36 'has a closing element recess 39, 39' for W '. Other_Casedocuments Palent P409- P4090Û697SE00 09Û903 beskdoc 10 15 20 25 30 Receiving the closing element 7. The insertion mouths 38, 38 'of the end basins 35, 35' are accessible from the outside of the post via rectangular holes 40 received in the U-profile-shaped element 4 of the post, which holes are suitable can be formed with a break plate arranged as a lid, which normally covers the hole, but by a simple operation by means of a hand tool, such as a chisel or the like, can be removed. As a result, the post 3 and associated lock 6 can be easily adapted on site to different types of door constructions, for example doors of swing or sliding type.
    As can be seen from a closer study of Figures 5, 6, the insertion orifice 38, 38 'for the upper and lower end plates 35, 35' are oriented perpendicular to each other, which makes it possible to use the uniform door lock for cooperation with both sliding doors and revolving doors. Furthermore, the end plates 35, 35 'and associated pivots 36, 36' are mirror-symmetrically designed with corresponding insertion mouths 38, 38 'located on either side of a vertical plane 41 which cuts through the center of the door lock 6 perpendicular to the main plane of the closed door 2. This mirror symmetry further contributes to the flexibility of the door lock 6 in that it makes it possible to use the door lock for both right- and left-hung doors of said revolving or sliding door type.
    In the embodiment shown here, the insertion opening 38 'of the lower end plate 35' is directed perpendicularly out from the main plane of the closed door and thus intended for co-operation with the closing element 7 of a revolving door, while the insertion opening 38 of the upper end plate 35 is directed parallel to the main plane plane. thus intended for cooperation with a closing element 7 of a sliding door. Fig. 7 shows a more detailed example of a house. The door lock 6 is used in combination with a laterally sliding door, so-called sliding door. Depending on the selected door type, the door lock and the closing element are arranged at such a mutual height that they are level with each other and the closing element 7 can be inserted into the insertion mouth of the relevant end plate and a rotating drop arranged therefor. This is conveniently done by the door lock 6 with the two end plates 35, 35 ', by interaction between pin and hole, being mountable at different heights in the post 3, the door lock being fixed in position at a suitable height in the post in relation to the closing element 7 of the door 2.
    Since the function of the door lock 6 is essentially identical regardless of whether it is used with a revolving door, sliding door or right or left-hung door, in the following, for the sake of simplicity, only the locking action of one end block 35 'with associated rotational closing element 7 of that door 2 of the oscillating type shown in more detail in the example of Figs. 5 and 6.
    With reference to Figs. 5 and 6, the closing element 7 of the door 2 is accommodated in 36 'to be described in more detail. Namely the case relating to the example of the closing element recess 39 'included in the rotary case 36' when the door is closed. The pivot case 36 'has a locking formation 42' intended to cooperate with the pivot lock 10. The pivot case 36 'is rotatably mounted on the shaft journal 27 for pivoting and a horizontal axis 27 for pivoting and a horizontal axis. is balanced by the influence of the force of pair-acting compression springs 43 to strive for an open position for receiving the closing element 7. Or conversely the compression springs 43 contribute to spring-loaded operation of the rotary drop 36 'when it receives the closing element 7 during closing of the door 2. Adjustment of the rotary drop 36 'towards a locked and interlocked position thus takes place in the direction of said spring force. the pivot lock 10 forms part of the control lever 8 extending vertically through the post 3. As best seen in Figs. 1 and 2, the adjusting rod 19 is guided in an upper and lower bushing 44 in the post 3 and is arranged continuously through a circular hole 45 in the end plate 35 'which also to some extent serves as a guide for the adjusting rod in the shaft direction. The pivot lock 10 comprises a first thickened portion 46 in the form of an annular sleeve in which the enclosing adjusting rod 19 is arranged to run axially or in the axial direction through the hole 45 of the end plate 35 when lifting or lowering the control lever 8. The sleeve 46 can be fixed at any It should be understood that the sleeve 46, by being fixed at a suitable height after the adjusting rod 19, can serve any of the upper or lower pivots 36, 36 ', and thus also either the upper or lower end plate 35, 35. ”. The locking formation 42 'of the pivot 36' comprises a circular arcuate recess 47 in the cam-shaped rear edge portion 48 of the pivot where said recess corresponds to a part of the outer periphery of the sleeve 46. As best seen in Fig. 6, the adjusting rod 19 and in addition the sleeve 46 can be pushed or lowered into the hole 45 'of the end plate 35' towards a locked position where the closing element 7 of the door 2 is accommodated in the associated insertion opening 38 'and the door is closed. The sleeve 46 and the recess 42 'in the rear edge portion 48' of the torsion drop 36 'with locking formation 42' can thus work against each other during interlocking by engaging in mutual locking engagement where the torsion drop is blocked against rotation. As mentioned above, the locking engagement takes place by co-operation between the sleeve 46 of the adjusting rod 19 and the circular arcuate recess 4 of the rotary case 36. Figs. 5 and 6 show a locked position where the door 2 is locked and the closing element 7 is received in the rotating element recess 39 '. turn is locked against rotation of the sleeve 46 of the adjusting rod 10 on the adjusting bar 10 by sliding it down into the hole 45 of the end plate 35.
    The door lock 2 can be reversed to the open position by lifting the adjusting rod 19 out of the locking position in which the sleeve 46 included in the rotary lock 10 is brought out of its locking position against the locking formation 42 'of the rotary case 36', i.e. against the circular arc-shaped recess 47 in the cam-shaped rear edge portion 48. In practice this is done by pulling the adjusting rod 19 upwards through the hole 45 'of the end plate 35. With the control lever 8 lifted out of the locking position the rotary drop 36' is released which is driven towards open position. door 2 can be opened. Again, with reference to Fig. 6, it should be understood that the door lock 6 cannot be adjusted in the locking position unless the closing element 7 of the door 2 is correctly accommodated in W '. Other_Casedocuments Patent P409- P40900697SE00 090903 beskdoc 10 15 20 25 30 35 7 the door lock and the door are properly closed. This is due to the locking action which occurs between the sleeve 46 of the adjusting rod 19 and the circular arc-shaped rear edge portion 48 of the rotary drop 36, which locking action prevents the operating lever 8 from being lowered into the locked position.
    More specifically, the rear edge portion 48 of the swivel 36 'has been shaped to prevent the sleeve 46 of the adjusting rod 19 from sliding down into the hole 45 * of the end plate 35 as long as the door is not properly closed and the swivel, 36', by the action of the closing member 7 of the door 2. brought in to engage its retracted interlock or locking position.
    Referring to Figs. 3 and 4 and as mentioned above, the interlocking mechanism according to the invention comprises a control lever lock 11 which by means of a locking mechanism 14 locks the control lever 8 against adjustment in the direction of the interlocking position as long as the elevator car is in a place other than the current ground plane.
    The function of the nlanover lever lock 11 is controlled by the position of the lift with the task of only allowing the control lever 8 to be moved out of the interlock position when the lift is on the current ground plane. As mentioned here initially, the locking mechanism 14 comprises a locking lug 15 which in the locked position projects substantially in a horizontal direction over a counter surface 13 arranged to the lower part of the adjusting rod 19 which is formed in the transition area between the periphery of the rod and the thickened portion. The counter surface 13 forms an upper side of a part of a second thickened portion 46 arranged in the lower end of the adjusting rod 19. The locking mechanism 14 is designed such that the locking lug 15, under the influence of a force such as from a spring or the like, tends to be in a locked condition with the locking lug 15 in locking engagement with the counter surface 13.
    The following describes the locking mechanism 14 arranged partly at an elevator of the type having an elevator car provided with a ramp 51 which can be lowered towards the ground plane, the mechanism being designed so that the ramp in the lowered position allows the interlocking mechanism arranged on the ground plane to be lifted. the kind having an elevator car provided with cam curve 52, the mechanism being a cam follower mechanism with such a path of movement that the interlocking can be canceled when a follower included in the mechanism comes into contact with a cam arranged on the elevator car. Said alternative embodiments are shown in Fig. 3 and Fig. 4, respectively, and it should thus be understood that the locking mechanism 14 can be designed in a number of different ways depending on the construction of the elevator.
    Fig. 3 shows the locking mechanism 14 formed as a pedal-like member 60 with a two-armed lever 61 which is pivotable about a hinge pin 62 and at its one end provided with a fork-shaped locking lug 15 having an insertion groove 63 with a width corresponding to the diameter of the adjusting rod 19 and other end provided with an actuating portion 64 designed for co-operation with the free edge of a ramp 51 which can be folded down from an elevator car. By the action of a spring 65 arranged to the two-armed lever 61, the locking lug 15 of the two-armed lever 61 tends to be normally locked the post recessed position in W: Other_Casedocuments Patent P409- P40900697SE00 090903 besk.doc 10 15 20 25 3Ü 35 8 which the adjusting rod 19 is locked against movement in the axial direction by co-operation with the fork-shaped lock 15 in the case shown in Fig. 3. In the exemplary case, however, the inverted position is shown in which the fork-shaped locking lug 15 is adjusted out of locking engagement with the lower second thickened second of the adjusting rod 19 portion 49 in that the ramp 51 is lowered and with its weight resting against the actuating portion 64 of the two-armed lever 61. In this position the locking mechanism according to the invention is in a locking position where the control lever 8 is no longer blocked by the locking mechanism 13, but where the control lever is still in place a locked locking position where the door is locked.
    Fig. 4 shows the locking mechanism 13 designed as a linkage system comprising a knee joint mechanism angled in a vertical plane consisting of a first and a second two-armed lever 70, 71 which are spaced apart and pivotable about a respective pivot 72, 73, the two-armed lever being One arm at its free end is provided with a locking lug 15 and the other double-armed lever 71 one arm is at its free end is provided with a follower 74 for a cam curve 52. The two levers are at their other arms via a respective shaft pin 77 , 78 so articulatedly connected to a link arm 79 that the parts together form a parallelogram which can pivot in said vertical plane perpendicular to the main plane of the closed door 2. The entire link system is furthermore so balanced that the locking lug 15 tends to be in a locked position recessed against the post in which position the adjusting rod 19 is locked against movement in the shaft direction by cooperation with the locking lug 15 sliding into a position above the counter surface 13 of the lower second of the adjusting rod 19 thickened portion 49. In the case exemplified in Fig. 4, the link system 70, 71, 79 included in the locking mechanism 14 is shown in a position where the follower 74 is in co-operation or contact with a cam curve 52 arranged on the elevator car. The contact between the follower 74 and the cam curve 52 thus forms a pivot point 80 for the link system which prevents the follower from "falling out" at the lost pivot point 80 if the control lever 8 and thus the adjusting rod 19 is actuated upwards from the locked position.The link system is designed so that the control lever 8 and associated adjusting rod 19 from their normal locking position can be switched to a released unlocked position in case the follower 74 is in contact t with said cam curve 52 and is prevented from "falling out", i.e. in cases where the elevator car is on the current ground plane. In all other cases where the elevator car is located in a place other than the current ground plane, ie. in the positions where the follower is not affected by the cam curve, the link system goes into a blocking position in any attempt to move the control lever 8 and thus also the associated adjusting rod 19 in the vertical direction upwards from the locking position.
    The interlock described above works in the following way: a) Without a lift basket at the current stop; there is then no cam curve 52 in front of the follower 74 which is not prevented from "falling out" whereby the articulation point 80 is thus missing. W: Other_Casedocuments Patent P409- P40900697SE00 090903 besk.doc 10 15 20 25 30 9 is missing, alternatively the ramp 51 is not lowered against the actuating portion 64. If the control lever 8 and thus the adjusting rod 19 is then actuated upwards, the door 2 will remain locked with safety in an interlocked position through the locking units connected in series. Firstly through the control lever lock 11 which in the interlocked position locks the control lever 8 against adjustment from the pre-locking position by co-operation between the locking lug 14 and the lower second thickened portion 49 of the adjusting rod 19. Secondly through the pivot lock 10 which in the interlocked position locks against the door lock 6 out of the locking position when the closing element 7 is accommodated in the lock by co-operation between the sleeve 46 and the locking formation 42 'of the rotary drop. In this condition, the door 2 thus remains locked with double security. b) With elevator car at the ground floor; cam 52 is now in front of the follower 74 and thus also the pivot point 80, alternatively the ramp 51 is lowered towards the actuating portion 64. If now the control lever 8 and thus the adjusting rod 19 is actuated upwards, each of the two series-connected locking units will go out of their locking positions and door 2 to be released. First, by preventing the follower 74 from "falling out" so that the articulation point 80 occurs, allowing the locking lug 15 to pivot away and thus the lower second thickened portion 49 of the adjusting rod 19 to pass unhindered past the locking lug 14 during the upward movement of the adjusting rod. 51, the ramp is of course lowered towards the actuating portion 64 and the locking unit is switched from the locking position by the locking lug 15 pivoted out of the locking engagement with the lower second thickened portion 49 of the adjusting bar 19. Secondly by the pivot lock 10 exiting its interlocking position. hole 45 and thus the sleeve 46 is moved out of its locking position against the locking formation 42 'of the pivot 36. By the action of the pivot 36' spring pair 43, the door 2 is driven towards the open position.
    Of course, the sensing third locking unit 12 by means of the switch unit 23 ensures that the lift cannot be started if the door 2 is not properly closed by switching off the power to the lift's drive motors if the interlock should not be set in a correct interlocking position.
    The invention is limited to what is described above and that shown in the drawings, but can be changed and modified in a number of different ways within the scope of the inventive concept stated in the appended claims.
