    "Key lock"
    Technical Field This invention relates to a lock for a gate or door, and more particularly to a security lock for exterior doors, gates or fences that allows to open the gate or door with a key.
    Background [02] Locks for gates, doors and fences are known. EP1118739 describes such a lock. The lock has a night bolt and a latch bolt, both of which can be operated so that they can be placed in a retracted or protruding position. The dead bolt is operated by a dead bolt lever. The latch bolt is operated by a latch bolt lever connected to a handle. The lock further has a key-operated cylinder with a rotating drive cam. The rotating drive cam engages the dead bolt lever to move the dead bolt between the retracted and the projecting position. In both of these positions the dead bolt is locked by means of a locking means that can be moved upwards, against the force of a spring, by means of the rotating drive cam to unlock the dead bolt just before it is moved by means of the rotating drive cam . The lock further has a second turn latch lever rotatably mounted on the frame of the lock to move the latch bolt from its projecting position to its retracted position and a second turn latch pusher connected to the second turn latch lever and the night latch lever to the second turn latch bolt rotation. The rotating drive cam engages the second latch pusher revolution to move the latch bolt through the operation of the key of the key operated cylinder.
    [03] A problem with this known lock is that when the dead bolt encounters a lot of resistance during its movement to the protruding position of the dead bolt, the rotating drive cam and the dead bolt lever can be forced into a relative position in which it is no longer possible to move the dead bolt lever. to run through the rotating drive cam. In particular, the rotating drive cam may become trapped between the free end of the dead bolt lever and the engagement portion of the second latch pusher revolution when the dead bolt is not correctly locked by the lock locking means and is pushed back in by a spring force that is on the deadbolt is exercised. In the event that the rotating drive cam would have passed beyond the engagement portion of the second revolution day bolt pusher, it becomes stuck under that engagement portion. In these situations the night bolt can no longer be moved and the lock is blocked. An intervention by a technician is required to unlock the locked lock.
    DESCRIPTION OF THE INVENTION It is an object of this invention to provide an improved lock that solves the above mentioned problems.
    This object is achieved according to the invention with a gate or door lock that has the technical features of the first independent claim. The lock comprises a frame; a dead bolt that is slidably mounted on the frame and adapted to shift between a retracted position and a projecting position; a locking means adapted to move up and down to lock the dead bolt in its retracted position and in its projecting position; a dead bolt lever connected to the dead bolt and pivotable about a pivot relative to the frame between a first extreme angular position in which the dead bolt is in its retracted position, and a second extreme angular position in which the dead bolt is in its projecting position is located; a latch bolt mounted slidably between a retracted position and a protruding position on the frame and pressed to its protruding position by a spring; a second rotation latch bolt lever rotatably mounted on the frame and adapted to move the latch bolt from its projecting position to its retracted position upon rotation; a second latch bolt pusher connected to said second latch bolt lever and said latch bolt lever and adapted to pivot said second latch bolt lever to move the latch bolt from its projecting position to its retracted position; and a key-operated cylinder provided with a rotating drive cam adapted to engage said locking means to move said locking means upward to unlock the dead bolt in its retracted position and in its projecting position; said second latch pusher rotation, to move said second latch pusher upward to rotate the second latch bolt lever to move the latch bolt to its retracted position; and said dead bolt lever to move the dead bolt from its retracted to its protruding position and vice versa. The dead bolt lever includes a first engagement portion to engage the rotating drive cam when said rotating drive cam rotates in a first direction to cause the dead bolt lever to rotate from its second to its first extreme angular position, and a second engagement portion to engage the rotating drive cam when said rotating drive cam rotates in a second direction, opposite to said first direction, to cause the dead bolt lever to rotate from its first to its second extreme angular position. The second latch pusher includes a second rotation engagement portion to engage the rotating drive cam when said rotating drive cam pivots further in said first direction with the dead bolt lever in its first extreme angular position to move the second latch pusher upward. To prevent the lock from locking when the rotating drive cam would have passed the second engagement portion on the dead bolt lever without the dead bolt being locked in its protruding position by the locking means, the dead bolt lever includes an auxiliary engagement portion to engage the rotating drive cam when said rotating drive cam rotates in said second direction to cause the dead bolt lever to rotate from an angular position between its first and second extreme angular positions to its second extreme angular position, said first engagement portion being located between said auxiliary engagement portion and said second engagement portion; and the second latch bolt pivot comprises a lateral engagement portion for lateral engagement with a distal end of the rotating drive cam, said lateral engagement portion extending from said second rotation engagement portion to the dead bolt lever in the second extreme angular position of the dead bolt lever.
    [06] This lock improves reliability compared to the current state of the art. By providing the auxiliary engagement portion adapted to cause the dead bolt lever to rotate when the rotating drive cam rotates further after engaging the second engagement portion of the dead bolt lever, the lock can never get blocked in a position where the dead bolt does not engage in its protruding position position and the rotating drive cam has passed the second engagement portion. When the lock enters this latter state in the embodiment of the invention, the rotating drive cam can be rotated to engage the auxiliary engagement portion of the dead bolt lever and to move the dead bolt to its projecting position. The lateral engagement portion of the second latch pusher revolution also prevents the rotating drive cam from getting stuck between the free end of the dead bolt lever and the second rotation engagement portion of the second latch pusher revolution.
    [07] In a preferred embodiment of the lock according to the invention, the dead bolt lever comprises a stop portion which cooperates in said second extreme angular position of the dead bolt lever with a stop on the frame, to prevent further rotation of the dead bolt lever when the rotating drive cam in said second direction is pushed against the auxiliary engagement portion of the dead bolt lever with the dead bolt lever in its second extreme angular position.
    This arrangement prevents the dead bolt from being pushed beyond its protruding position when the rotating drive cam of the key-operated cylinder acts on the auxiliary engagement surface of the dead bolt lever. In this way the locking means can reliably lock the dead bolt even when it has been moved to its projecting position by means of the auxiliary engagement surface.
    In another preferred embodiment of the lock according to the invention, the first, the second and the auxiliary engagement part are located on a first arm of the dead bolt lever, said first arm extending from said pivot point.
    Said first arm preferably has a free end which, in said first extreme angular position of the dead bolt lever, forms a stop for said rotating drive cam when it rotates in said first direction.
    [11] In this way, rotation of the rotating drive cam is limited in said first direction, so that it is reliably prevented from going beyond the second revolution engagement portion of the second revolution day bolt pusher when this pusher is moved upwards by means of the key actuator. cylinder.
    [12] In another preferred embodiment of the lock according to the invention, said first arm, in the second extreme angular position of the dead bolt lever, forms a bend around the path of the distal end of the rotating drive cam of the key-operated cylinder, which allows the rotating drive cam to pivot from said first engagement portion to said auxiliary engagement portion and vice versa with the dead bolt lever in its second extreme angular position.
    [13] This ensures that after passing the second engagement portion of the dead bolt lever, and the second rotation engagement portion of the second rotation latch pusher, the rotating drive cam ensures that the night bolt is not pushed all the way into its protruding position in which it is locked by the locking means, can further rotate, in the second direction, to engage the auxiliary engagement portion of the dead bolt lever. In this position, a further force can be exerted on the night bolt to push it to its projecting position; In contrast to the second engagement portion of the dead bolt lever, it is impossible that the rotating drive cam would pass beyond the auxiliary engagement portion even if a large force is applied to the rotating drive cam and to the dead bolt.
    [14] In another embodiment of the lock according to the invention, the dead bolt lever on the first arm comprises a first protrusion that forms the first engagement portion and the auxiliary engagement portion.
    [15] This structure has the advantage that the engagement portions can easily be formed in production. Furthermore, this makes it possible to position the engagement portions very accurately with respect to each other.
    [16] In a further embodiment of the invention, the first arm comprises a second protrusion on the first arm, which forms the second engagement portion.
    [17] A structure with several protrusions allows for different engagements in an easy to produce manner that requires little space.
    In another embodiment of the invention, the first engagement portion and said second engagement portion are opposite each other.
    [19] In a further embodiment of the invention, the dead bolt lever comprises a second arm which is adapted to form a connection with the second rotation latch pusher and which also extends from said pivot point.
    [20] The key operated cylinder is preferably located between the dead bolt and the pivot point of the dead bolt lever, and the second arm of the dead bolt lever is preferably located between the key operated cylinder and a face plate of the lock through which the dead bolt extends out of the key lock.

    Embodiments of the Invention [23] This invention will be described with reference to particular embodiments and to certain drawings, but the invention is not limited thereto. The invention is only limited by the claims. The described drawings are purely schematic and are not limitative. In the drawings, the size of some elements may be exaggerated and not drawn to scale for illustrative reasons. The dimensions and the relative dimensions do not necessarily correspond to actual ratios for putting the invention into practice.
    [24] Furthermore, the terms first, second, third and the like are used in the description and in the claims to distinguish between similar elements and not necessarily for describing a sequential or chronological order. The terms are interchangeable under suitable circumstances and the embodiments of the invention may operate in sequences other than described or illustrated herein.
    [25] In addition, the terms top, bottom, top, bottom and the like in the description and in the claims are used for descriptive purposes and not necessarily to describe relative positions. The terms so used are interchangeable under suitable conditions and the embodiments of the invention described herein may operate in orientations other than those described or illustrated herein.
    [26] Furthermore, even when referred to as a "preferred embodiment", the various embodiments are to be seen as examples of how the invention can be practiced and not as limiting the scope of the invention.
    [27] The term "comprising" used in the claims should not be construed as being limited to the elements or steps listed thereafter; it does not exclude other elements or steps. It must be interpreted as specifying the presence of the aforementioned characteristics, wholes, steps or components referred to, but does not exclude the presence or addition of one or more other characteristics, wholes, steps or components, or groups thereof. Thus, the scope of the expression "a device comprising A and B" should not be limited to devices consisting of only components A and B, but with regard to this invention, the only named components of the device are A and B, and furthermore the conclusion must be interpreted as comprising equivalents of these components.
    Figures 1A and 1B show the lock of the current state of the art described in EP1118739, wherein the rotating drive cam 14 of the lock cylinder 13 is forced into a relative position with respect to the dead bolt lever 58 in which the rotating drive cam 14 is no longer able to turn the dead bolt lever 58. In this position, the cam 14, when turned to the right, will engage the second latch pusher 72 revolution and attempt to move it downward, which is not possible because the second latch pusher 72 rotation is connected to the night latch lever 58 on one side and with the second rotation latch lever 73 in such a manner that the second rotation latch pusher 72 can only be moved upward to rotate the second rotation latch lever 73 counterclockwise in the view of Figures 1A and 1B. Furthermore, when it is turned to the left in this relative position, the rotating drive cam 14 will engage the nose of the dead bolt lever 58, ie the free end of the dead bolt lever 58, and attempt to move it to the left, which is also not possible. . The lock is thus completely blocked in this relative position.
    Figure 2 shows a lock according to a preferred embodiment of the invention. The lock is provided to be mounted against a profile 120, in most cases a tubular profile of a gate, fence, door, etc. The profile is provided with holes 121 to receive both the latch 18 and the latch 41. Therefore, when it is said that the latch bolt or night bolt is in a retracted position, this does not mean that the bolt has been retracted within the lock (ie behind the face plate 3 of the lock), but that it has been retracted into the corresponding hole 121 of the tubular profile 120 to which it is attached, or that it projects a small distance from this profile. In its extended / protruding position, the bolt extends over a greater distance from the profile to which it is mounted. The difference between these two distances is called the stroke of the lap.
    The lock of the embodiment of Figure 2 comprises a frame 1 consisting of a base plate 4 and a front plate 3 connected to the base plate 4. When the whole of the base plate 4 and the front plate 3 are in a housing (not shown) is mounted, the front plate 3 engages the peripheral edge of the housing. The base plate 4 has a raised edge 5 on its front side and two raised edge parts 6 and 7 on its rear side. The front plate 3 is connected to the base plate 4 by connecting the front plate 3 to the raised edge 5 of the base plate 4. Two threaded bushes connected to corresponding holes in the raised edge 5 and the front plate 3. Screws 9 and spacers 11 are provided to secure the lock laterally to a profile 120 of a gate.
    [31] A cylinder 13 is attached to the base plate 4 via a screw 15. In an embodiment of the invention, the cylinder can be a so-called Euro cylinder in accordance with the DIN V18254 / 07.91 standard. The key-operated cylinder 13 includes a rotating drive cam 14 that rotates around a central axis of the cylinder to operate the lock as described below. The screw 15 is screwed into a tapping hole of the cylinder through corresponding holes in the face plate 3 and the raised edge 5 of the base plate 4. A cylinder support member 82 is provided on the base plate 4 in such a way that the cylinder 13 is supported in two places in two corresponding openings 83 and 84.
    The lock further comprises a latch bolt 18 slidably mounted in the frame 1 by moving into a corresponding opening in the raised edge portion 6 and in a second corresponding opening in the raised edge 5 and / or in the front plate 3. In the embodiment of Figure 2, the second corresponding opening for the latch bolt is formed by folding the face plate into a hole of the raised edge 5. In alternative embodiments, this second corresponding opening is provided in a different manner. A compression spring 23 is provided around the latch bolt 18 to press this bolt to its projecting position. The compression spring 23 acts between the upright edge portion 6 and a screw or pin 53 on the latch bolt 18. To bring the latch bolt 18 to the retracted position by means of the handles to open the gate, a rectangular axis of the handles becomes a inserted a corresponding hole in a follower 24. This follower 24 is in turn connected to a latch bolt lever 25 which follows the rotation of the handles and which engages the latch bolt 18 to move it against the force of a main spring 26, which is a coil spring arranged around the follower 24 . The main spring 26 presses the latch bolt lever 25 and thus the follower 24 and the handles to their rest positions.
    The latch bolt 18 in the embodiment of the figures is made of steel, more specifically of stainless steel, which is a strong and weather-resistant material, but which is difficult to shape in the usual ways such as milling, etc. As will become apparent hereinafter , the latch can indeed have a rather complex shape, in particular to allow the distance over which it protrudes from the lock to be adjusted. The latch bolt 18 has two separate parts, namely a hollow part 27 and a more solid bolt portion 28. The solid bolt portion 28 is adapted to protrude from the lock into a lock catch. The solid portion 28 is removably mounted in the hollow bar portion 27. The bolt portion 28 can be mounted in two positions, namely a first position in which the slanted front is directed in a first direction and in a second position in which the slanted front is rotated axially over approximately 180 °. The latch bolt illustrated in the figures as well as an alternative latch bolt are described in EP1118739 which we integrate herein in its entirety.
    The lock further comprises a dead bolt 41. In the embodiment shown in the figures, the dead bolt consists of two parts: a hollow rod portion 42 and a bolt portion 42. The hollow rod portion 42 extends at least partially within the lock. The bolt portion 43 is adapted to cooperate with the lock catcher. Sliding means 47 is adapted to guide into slots 48 of the dead bolt. The position of the sliding means relative to the dead bolt 41 can be adjusted via the known technology of a set screw (not shown) in the longitudinal direction of the dead bolt 41 which is accessible via an axial passage in the bolt portion 43. In this way the distance can be over which the dead bolt 41 protrudes from the lock can be adjusted.
    The dead bolt is mounted on the frame 1, slidable between a projecting position (shown in Figure 3) and a retracted position (shown in Figures 6 and 7). The dead bolt 41 slides into corresponding openings in the raised edge portion 5 and the raised edge portion 7 of the frame 1. The dead bolt 41 is locked in both positions, protruding position and retracted position, by locking means 66. In one embodiment, the locking means 66 comprises a holding plate which can move up and down on the frame 1. As can be seen in the detail of Figure 2, the holding plate 66 has a horizontal slot 67 with an upward notch 68 at both ends. In the normal position, the holding plate is pushed down so that the sliding means 47 is in one of the notches 68 of the holding plate 66 and thus the dead bolt 41 is locked in one of its two extreme positions.
    [36] The movement of the dead bolt 41 is carried out by turning the key in the cylinder 13 and thus by turning the rotating drive cam 14. As shown in Figure 4, a movement of the rotating drive cam 14 results in the projecting position. counterclockwise (first direction: see arrow 92 in Figure 4) first in the engagement of the rotating drive cam 14 on the lower edge 71 of the holding plate 66, so that the holding plate 66 is lifted and the dead bolt 41 is unlocked. Then, when the rotation is continued counterclockwise as shown in Figure 5, the rotating drive cam 14 engages a first engagement portion 91 of a dead bolt lever 58 that is rotatably mounted about a pivot 59. A first arm 110 of the dead bolt lever 58 is such connected to the dead bolt 41 that a rotation of the dead bolt lever 58 around pivot 59 in the direction of arrow 92 results in a translation of the dead bolt 41 in the direction of arrow 94. In the embodiment of Figure 4, this is carried out by provided in the dead bolt lever 58 extending into a U-shaped part of the dead bolt 41 and the sliding means 47 is provided in the slot of the dead bolt lever 58. As shown in Figure 7, the rotating drive cam 14 continues to rotate in the first direction , counterclockwise, to retract the latch bolt 18 by means of a second latch push 72 and a second revolution latch bolt lever 73, which will be described in more detail below.
    [37] When the dead bolt 41 is in the retracted position (position of FIG. 6) and the rotating drive cam 14 is turned back in the second direction, clockwise (indicated by arrow 96), as shown in FIG. 8, the rotating one engages drive cam 14 into a second engagement portion 93 of the dead bolt lever 58. Because the dead bolt lever 58 is connected to the dead bolt 41 as discussed above, rotation of the dead bolt lever 41 in the second direction 96 results in a translation of the dead bolt 41 in the direction of arrow 98. Figure 9 illustrates the rotation and movement at a position substantially halfway between the retracted position and the projecting position of the dead bolt 41. The holding plate 66 is raised in that position. In Figure 10, the rotating drive cam 14 is further rotated clockwise until the holding plate 66 is no longer raised and the dead bolt 41 is locked in its projecting position. However, in some situations where forces act on the dead bolt 41 in the direction opposite to the translation 98, the drive cam 14 may pass beyond the second engagement portion 93 of the dead bolt lever 58 without the holding plate 66 moving down into the locked position of the dead bolt 41, and the dead bolt 41 moves backwards into the lock while the rotating drive cam 14 no longer contacts the second engagement portion 93. This is shown in Figure 11. Then, the rotating drive cam 14 engages when it is shown in Figure 12 is further rotated in the second direction, clockwise, into an auxiliary engagement portion 95 of the dead bolt lever 58 positioned so that engagement allows to rotate the dead bolt lever 58 clockwise about pivot 59 and thus the dead bolt 41 moves again to its projecting position. When the dead bolt 41 is in its end position (protruding position) as shown in Figure 13, the rotating drive cam 14 can be rotated counterclockwise and the holding plate 66 will move downward from its raised position to its original non-raised position and the dead bolt is now correctly locked. This is shown in Figure 14.
    [38] The dead bolt 41 has only two extreme positions (except that the distance over which it protrudes from the lock can be adjusted), namely a protruding position, shown in Figure 13, and a retracted position, shown in Figure 6. These two extreme positions correspond to the second and first extreme angular positions of the dead bolt lever 58, respectively. In the second extreme angular position of the dead bolt lever 58, a stop portion of the dead bolt lever 58, more particularly the free end 60 thereof, abuts against a stop. the frame, more particularly the front plate 3 (through a slot in the raised edge 5, which is not shown), so that the dead bolt lever 58 cannot be rotated further, in particular not when the dead bolt is pushed more outwards with the rotating drive cam 14 against the auxiliary engagement portion 95 of the dead bolt lever 58. Accordingly, in the lock of this invention, both the second Pipe portion 93 as the auxiliary engagement portion 95 of the dead bolt lever 58 intended to allow movement of the dead bolt lever 58 by means of the rotating drive cam 14 to the same second extreme angular position.
    [39] In the embodiment of Figures 2 to 14, the cylinder 13 is provided between the dead bolt 41 and the pivot 59. The pivot 59 is positioned such that the dead bolt lever 58 engages the dead bolt 41 at a first distance D1 from the pivot 59 and the rotating drive cam 14 engages the dead bolt lever 58 at a second distance D2 from the pivot 59 wherein the second distance D2 in any position is smaller than the first distance D1. This ensures a greater stroke of the deadbolt 41.
    Referring to Figures 6 and 7, the lock includes a second revolution pusher 72. The second revolution pusher 72 is slidably connected at its one end to a second arm 78 of the dead bolt lever 58 which also extends from the pivot 59 of the dead bolt lever 58. The second arm 78 of the dead bolt lever 58 is located between the key-operated cylinder 13 and the front plate 3 of the lock. In this way, the second rotation pusher 72 moves into and out of the path of the distal end 16 of the rotating drive cam 14. More specifically, the second rotation pusher 72 is in the first extreme angular position of the dead bolt lever 58, ie the position as shown in Figures 6 and 7 in which the dead bolt 41 is locked in its retracted position, in the path of the rotating drive cam 14, while the second pusher revolves in the second extreme angular position of the dead bolt lever 58, ie in the position as shown in Figure 10 wherein the dead bolt 41 is locked in its protruding position, not in the path of the rotating drive cam 14. The second rotary pusher 72 is provided with a slot 77 by means of which it is slidably connected to the second arm 78 of the dead bolt lever 58. The movement of the second rotary pusher 72 is configured such that it does not move in the path of the rotating drive cam 14 is in the protruding position of the dead bolt 41 as shown in Figures 4 and 10 and that it enters the path of the rotating drive cam 14 when the dead bolt 41 moves to its retracted position as shown in Figures 6 and 7.
    The second revolution pusher 72 is connected at its other end to the second revolution latch bolt lever 73 which is adapted to move the latch bolt 18 against the action of the compression spring 23 from a projecting position to a retracted position. The second turn latch lever 73 is rotatably mounted over the follower 24. The second turn latch lever 73 has a first lever arm 75 to engage the sliding means 36 on the latch bolt 18 and a second lever arm 101 for a rotatable connection to the second turn pusher 72 around pivot point 102.
    [42] In the position of Figure 6, i.e. after moving the dead bolt 41 from the protruding to the retracted position by rotating the rotating drive cam 14 counterclockwise (first direction), rotating the rotating drive cam 14 continues to rotate counterclockwise ( (ie, second rotation counterclockwise) the rotating drive cam 14 engages the second revolution pusher 72 at second rotation engagement portion 104. This engagement pushes the second rotation pusher 72 upward to cause the second rotation latch bolt 73 to rotate and thus retract the latch bolt 18 . This is shown in Figure 7.
    [43] As can be seen in Figure 7, the free end 60 of the dead bolt lever 58 not only limits the rotation of the dead bolt lever 58 in the second direction of rotation (clockwise), but also limits the upward movement of the second revolution day bolt pusher 72 by the rotating drive cam 14 in the first extreme angular position of the dead bolt lever 58. In this way, there is no danger that the rotating drive cam 14 would pass beyond the second revolution engagement portion 104 if it were turned too far in the first direction.
    [44] The second revolution latch pusher 72 not only has a second rotation engagement portion 104 that allows to push the pusher 72 upwards by means of the rotating drive cam 14, but also has a lateral engagement portion 109 intended to prevent the rotating drive cam 14 becomes stuck between the dead bolt lever 58 and the second rotation engagement portion 104 of the second rotation latch bolt 72. The lateral engagement portion 109 extends into the projecting position of the dead bolt 41, ie into the second extreme angular position of the dead bolt lever 58, from the second revolution engagement portion 104 to the dead bolt lever 58. It is arranged to engage laterally on the distal end 16 of the rotating drive cam 14 when the rotating drive cam 14 has passed the second engagement portion 93 of the dead bolt lever 58 and the dead bolt 41 was not locked by the locking means 66 e n moves back into the lock by an external force exerted on its free end. This situation is shown in Figure 11. In the case that the lateral engagement portion 109 would not be at the same level as the distal end 16 of the rotating drive cam 14, this rotating drive cam 14 would, in the situation shown in Figure 11, get stuck between the free end 60 of the dead bolt lever 58 and the second rotation engagement portion 104 of the second rotation latch pusher 72.
    The second rotary pusher 72 has a main portion 105 that bridges the dead bolt 41, a slot portion 106 provided with the slot 77, and an intermediate portion 108 between the main portion 105 and the slot portion 106, with a first stepped transition between the slot portion 106 and the intermediate portion 108 and a second stepped transition between the intermediate portion 108 and the main portion 105. The intermediate portion 108 forms the lateral engagement portion 109, which is located in the path of the distal end 16 of the rotating drive cam 14, while the slot portion 106 is located outside (behind or in front) the path of the rotating drive cam 14 so that the rotating drive cam 14 can rotate beyond this slot portion to engage the second revolution engagement portion 104 of the second rotation latch pusher 72.
