Description

[0001] The invention relates to a garbage can lock with a latch arranged in a lock housing, with a counter-locking part having a catch hook and with an opening slide which, when the lock housing is pivoted from a closed position about an opening pivot axis in an opening pivot direction to an open position, shifts linearly from a basic position to a displaced position due to the action of gravity, and which is coupled to the latch in such a way that the latter, with the catch hook, assumes a locking position in the basic position of the opening slide and a release position in the displaced position of the opening slide.

[0002] A generic waste bin lock is known from EP 0 509 932 B1. The locking device described therein has a latch pivotally mounted in a housing. The latch forms a locking hook that interacts with a catch hook of a counter-locking element. The lock housing can be attached to a container section of a waste container. The catch hook is associated with the lid. In the container's normal position, the lock housing is in a closed position. In this closed position, the latch is locked to the counter-locking element. The container lid can only be opened by operating the lock. Inside the lock housing is an opening slide. This opening slide is designed as a weight and can be moved from a home position to a displaced position. In the closed position of the housing, the slide returns to its home position.The direction of movement is upwards in the closed position. To ensure the container lid opens automatically when tilted for emptying, the opening slide is linked to the latch. Moving the opening slide from the open position to a tilted position moves the latch from a locking position to a release position. In the release position, the latch is disengaged from the catch, allowing the lid to open. The opening slide moves automatically from its home position to the tilted position when the container is tilted upside down.

[0003] From DE 197 08 193 C2, a locking device for the lid of a waste container is known, in which, instead of an opening slide, a pivotable weight is provided which interacts with a latch such that, during overhead emptying, the latch is moved from a locking position to a release position. This waste container lid also includes a locking mechanism by means of which the latch is fixed in its locking position when the container is not in its tilted position for overhead emptying. The locking mechanism is formed by a roller located in a vertically extending chamber of the housing and within the pivoting range of the weight.

[0004] WO 2005 / 111348 A1 describes a waste container lock with a pivotable weight inside, which, when pivoted, moves a latch from a locking position to a release position. Furthermore, it includes misoperation prevention elements that block the movement of the weight if the housing is not rotated in the prescribed direction.

[0005] The invention is based on the objective of further developing a generic waste bin closure in a way that is advantageous for use.

[0006] The problem is solved by the invention specified in claims 1 and 2.

[0007] The waste bin lock according to the invention can have a misoperation lock. This is formed by at least one movable misoperation lock element, which is associated with the opening slide. This misoperation lock ensures that the opening slide cannot be moved from its home position to the displaced position whenever the housing is pivoted about a different pivot axis than the opening pivot axis, or pivoted in a different direction than the opening pivot direction. As a result of this design, the latch is only moved from its locking position to the release position when the lock housing or the container equipped with the lock housing is pivoted in the prescribed direction, namely in the overhead emptying / tipping direction. For example, if the container is tilted...If the container is pivoted in a different direction, which can occur if it is tipped over, the latch remains in its locked position. However, proper emptying of the container is still possible, as pivoting the housing or the container connected to the housing around the opening pivot axis in the correct direction releases the catch, allowing the lid to open automatically. In a further development of the invention, the misoperation locking element is designed as a latch pivotable about an axis. The latch can be single-armed or double-armed. In a preferred embodiment, two latches are provided, with a first latch pivotable about a horizontal pivot axis relative to the home position and pointing upwards. A second latch can pivot about a vertical axis relative to the home position.This latch can be a two-armed latch. The latches preferably sit in recesses in the opening slide. The recesses are open towards a broad side of the opening slide. The arms of the latches can pivot out of this opening if the housing is not pivoted around the opening pivot axis in the prescribed opening direction. Each arm is associated with a locking bar that projects inwards from a housing wall. The locking latch, pivoted into the locked position, engages against this locking bar, thus preventing any displacement of the opening slide from its home position to the displaced position.

[0008] A first aspect of the invention provides that the opening slide forms a substantially S-shaped control groove. This control groove is formed by a slot whose two end sections run substantially parallel to the direction of movement of the opening slide. An intermediate section between the two end sections runs obliquely to the direction of movement of the opening slide. A control pin is guided in the control groove and is located on the free arm of a control arm of the latch. This causes the latch to pivot from a locked position to a released position during the linear displacement of the opening slide. The latch is designed with two arms. It is pivotable about a pivot axis fixed to the housing. It forms a latch head that carries a locking pin which interacts with the catch hook.The catch hook can be pivoted from the outside by operating a lock or similar mechanism, allowing the lid to be opened even when the latch is locked. The catch arm can also be pivoted from the inside to disengage the catch hook from the latch when it is in the locked position. This is possible without operating a lock, allowing a person accidentally trapped inside the container to free themselves. The pivot axis of the single-arm latch, which points upwards in its normal position, runs parallel to the opening pivot axis. This latch pivots into its locked position when the lock housing is rotated around the opening pivot axis, but the direction of rotation does not correspond to the opening pivot direction. The pivot axis of the double-arm latch runs perpendicular to the opening pivot axis.This latch pivots into one of its two locking positions when the lock is pivoted about an axis perpendicular to the opening pivot axis. In the previously described variant, the catch hook can be pivotally connected to the strike plate. Preferably, however, the catch hook is rigidly connected to the strike plate. It can be made of plastic and be integrally molded into the plastic housing of the strike plate. Alternatively, the hook can be formed from a metal part, in particular a stamped sheet metal part, which is firmly anchored in the plastic housing of the strike plate.

[0009] A second aspect of the invention provides that the trap can be pivoted not only by gravity-induced displacement of the weight component. The trap can also be pivoted by an opening aid. The opening aid can, for example, be pivoted by an operating handle of the opposing locking element. Preferably, the opening aid is pivoted by a cylinder lock or the like of the opposing locking element. The opening aid can be designed as a lever. Preferably, it will have a rocker-like shape. One arm of the opening aid forms an actuating arm, to which, for example, a locking element of the locking cylinder engages. However, the actuating arm can also be engaged from inside the container to effect an emergency opening. The working arm of the opening aid engages the head of the trap to move it. For this purpose, the head can be pivotally connected to a control arm of the trap.Preferably, the head can be displaced from the locked position against an elastic restoring force by actuating the opening aid. For this purpose, the working arm of the opening aid can engage a locking pin of the latch head to displace it against the restoring force of the aforementioned springs. Preferably, the latch head is pivotally movable relative to the control arm. A compression spring can be pre-tensioned to clamp the latch head against the control arm.

[0010] Stops are provided for this purpose. When the opening aid is pivoted, this preload is overcome. The latch head then leaves the locking position. It is moved over the hook. The hook has a ramp. The latch head, or rather the locking pin of the latch head, can slide along this ramp. In doing so, the latch head shifts relative to the control arm and then snaps into the locking position over the hook. In the solution to the problem discussed above, it is not necessary for the weight component to be formed by a slide. In the- In this design, the control pin is located approximately halfway along the length of the control arm. The control pin can have a diameter significantly smaller than the S-shaped control groove. At the end of the control arm is a retaining pin, which, in the opening slide's home position, rests in a retaining recess. In this design, a torque applied by pivoting the working arm onto the latch head is not transmitted via the control pin into the control slot, but rather via the retaining pin, which is positioned more favorably from a lever perspective, into the retaining recess. A further development of the misoperation lock provides that it can engage in a latching position with the locking bar. For this purpose, a clearance can be provided behind the locking bar into which a retaining projection of the misoperation lock element can engage. This increases operational reliability by providing a certain degree of vibration resistance.In a preferred embodiment of a latch forming the misoperation prevention element, it is slidably mounted in the opening slide. The recess in which the latch sits has a stop bar that the locking end of the latch can only overcome after it has moved linearly within the recess. For this purpose, the bearing axis of the latch rests in a bearing channel with a degree of play. A retaining arm can extend behind the locking arm of the latch, which sits in a receiving chamber of the slide. This measure also serves operational reliability, as the locking latch cannot enter the locked position due to vibrations during the proper pivoting of the lock housing.

[0011] Exemplary embodiments of the invention are explained below with reference to the accompanying drawings. These show: Fig. 1. In a top view with the housing cover removed, the lock mechanism is shown in the locked position.

[0012] The lock essentially consists of two parts: a lock housing 1, which can be mounted in the upper area of ​​the inner wall of an upwardly open container; and a lid hinged to the opposite edge of the container's opening, to which a mating locking element 3 is assigned. The mating locking element 3 has a catch 4 projecting downwards from the lid. The catch 4 can be moved from a locked position to an unlocked position against the restoring force of a spring (see Figure 1). Fig. 3) can be pivoted. This can be done by operating a lock located outside the container on the top of the lid, which can be operated by a key or a multi-sided tool. The catch hook 4 can also be pivoted from the inside, so that emergency opening from the inside is possible.

[0013] The lock housing, located at the edge of the container, has a catch slot for the catch hook 4. The catch slot contains the trap head 19 of a trap 2. The trap 2 is two-armed and pivotally connected to the lock housing 1 about a pivot axis 18 fixed to the housing. The trap head 19 is fork-shaped. The two prongs hold a locking pin 20, which can be engaged by the catch hook 4 in the locked position.

[0014] Within the lock housing 1, the latch 2 continues with a control arm 17. At the end of the control arm 17 is a control pin 16, which engages in a control groove 15 of an opening slide 5. The control groove 15 has the shape of an S-shaped slot, with the two end sections 15', 15" of the control groove 15 running parallel to a displacement direction of the opening slide 5. The middle section 15'' of the control groove, located between the two end sections 15', 15''', runs obliquely to the displacement direction of the opening slide 5.

[0015] The opening slide 5 is made of metal and forms a weight component. The direction of movement of the opening slide 5 is specified in the Fig. 1, Fig. 2 to Fig. The closed position of the closure shown in section 3 indicates the vertical direction. It can be adjusted from the position shown in Fig. 1 depicted position in the in Fig. The position shown in 2 can be shifted when the lock housing 1 is rotated about the opening pivot axis 6 in the direction of rotation 6'. The shift of the opening slide 5 into the position shown Fig. The displaced position shown in section 2 is caused by the action of gravity. The opening pivot axis 6 of a closure attached to a waste container runs parallel to the pivot axis of the lid, which secures the closure in the closed position.

[0016] During the relocation from the to Fig. 1 basic position shown in the in Fig. In the displaced position shown in Figure 2, the control pin 16 moves through the control groove 15. When passing through the first section 15', the trap 2 is not pivoted. Only when the control pin 16 enters the middle section 15'' is the trap 2 displaced by the Fig. 1 shown locking position into the in Fig. The release position shown in Figure 2 is shifted, in which the locking pin 20 is disengaged from the catch hook 4. In the final section of the movement, the control pin 16 enters the end section 15''' of the control groove 15.

[0017] The opening slide 5 has two recesses 11, 12 open towards one of its broad sides. A single-armed latch 7 is located in the recess 11. The latch 7 is pivotable about a bearing axis 9 which runs horizontally in its home position. The bearing axis 9 is formed by two bearing pins projecting laterally from the latch 7 in opposite directions and which are located in corresponding bearing recesses in the opening slide 5. The bearing axis 9 is located at the lower end of the latch 7. The arm of the latch 7 projects upwards in its home position. In the direction of movement of the opening slide 5, a locking bar 13, which is associated with the housing wall, is located in front of the single-armed latch 7 in its home position. The locking bar 13 projects inwards from the housing cover. It lies in the path of movement of the latch 7. If the opening of the recess 11 points downwards during the pivoting movement of the lock housing 1, the single-arm latch 7 engages the Fig. The position shown in section 5 is entered. It is in a locked position and, by stopping against the locking bar 13, prevents the opening slide 5 from being moved into the displaced position. However, if the opening of the recess 11 points upwards, as shown in the Fig. As shown in Figure 4, the latch 7 rests in the recess 11, so that it does not interfere with the movement of the opening slide 5. Due to this design, the opening slide 5 can only move into its displaced position if the rotation about the opening pivot axis 6 occurs in the correct direction, namely in the opening pivot direction designated 6'. The latch 7 is mounted so freely in the recess 11 that it can pivot solely by the force of gravity.

[0018] A second latch 8 is located in a second recess 12, which is open towards the same broad side surface as the recess 11. The latch 8 has two locking arms 8', 8'' which lie completely within the recess 12 when the opening of the recess 12 faces upwards, as shown in the Fig. Figure 6 shows. If the opening of the recess 12 does not point upwards, but for example to a side, as shown in the Fig. Figure 7 shows that, as a result of the action of gravity on the latch 8, an arm 8', 8'' emerges from the opening of the recess 12 and lies in front of a locking bar 14, 14' of the lock housing 1.

[0019] This results in the opening slide 5 being locked in place when the lock housing 1 is pivoted about a horizontal axis perpendicular to the opening pivot axis 6, as is the case with the Fig. 7 shows.

[0020] The pawl 8 is formed by an essentially semicircular weight element, the axis of rotation of which lies approximately at the imaginary center of the circle. With the opening of the recess 12 facing upwards, as shown by the Fig. As shown in Figure 6, the latch 8 hangs pendulum-like below the bearing axis 10, with which the latch 8 is mounted in the recess 12. Here too, the bearing axis 10 is formed by two bearing pins projecting from the broad side of the latch 8, which lie in bearing recesses of the opening slide 5.

[0021] Due to the first slot section 15' running parallel to the displacement direction of the opening slide 5, the opening slide 5 can initially shift slightly in the event of incorrect operation until one of the latches 7, 8 abuts its associated locking bar 13, 14, 14' without the latch 2 pivoting. The latch 2 is therefore only pivoted when the opening slide 5, with its upward-facing recesses 11, 12, is pivoted about the opening pivot axis 6 in the direction of the opening pivot 6'. The opening pivot direction corresponds to the overhead tipping emptying direction of the container.

[0022] In the Fig. Figures 8-10b show a second embodiment of the invention, which has essentially the same functionality as the one described in the Fig. Figures 1-7 illustrate the first embodiment. Unlike the first embodiment, however, the trap 2 is not a single piece, but rather a two-piece design. It has a trap head 19 that is pivotally mounted to the control arm 17. In this embodiment as well, the trap is pivotally mounted about an axis of rotation 18 relative to the housing 1 and pivots when the weight 5 moves as described above. This causes the locking pin 20 to disengage from the hook 4. In this embodiment, the trap head 19 is displaceable about a bearing pin 24. One bearing section of the trap head 19 sits in a bearing pocket of the control arm 17, which is located directly next to the axis of rotation 18. A stop 27 of the trap head 19 lies in front of a counter-stop 28 of the control arm 17. A pre-tensioned compression spring 25, mounted in a bearing pocket 26, acts on the trap head 19 in the direction of the stops 27, 28.Due to the preload of the compression spring 25, the two elements 17 and 19 of the trap 2 possess a certain stiffness that is sufficient to enable the above-described function when the container is turned upside down.

[0023] The counter-locking part 3 has an operating handle 23, which in the exemplary embodiment is formed by a cylinder lock that can be operated with a triangular key. A locking element of the cylinder lock 23 acts on the actuating arm 30 of an opening auxiliary element 22. The opening auxiliary element 22 is pivotable about a pivot axis 29. The opening auxiliary element 22 forms a two-armed lever. The first lever arm is formed by the actuating arm 30 and the second lever arm by the working arm 31. Overall, the opening auxiliary element 22 thus has the form of a rocker, with the pivot axis 29 being associated with the counter-locking part 3.

[0024] The working arm 31 of the opening aid 22 lies in the area of ​​the hook 4, which is made of the same material as the strike plate housing 3. In the locked position, the locking pin 20 of the latch head 19 rests on the flank of the hook. When the opening aid 22 is pivoted, the working arm 31 of the opening aid 22 engages the locking pin 20 and pushes the locking pin 20 over the flank of the hook into a release position. In this position, the locking pin 20 is released from the hook 4, so that the strike plate 3 can be removed from the lock housing 1. The waste container, on whose lid the strike plate 3 is located, can then be opened.

[0025] By acting upon the locking pin 20 by the working arm 31, the latch head 19 is pivoted relative to the control arm 17. This pivoting occurs against the restoring force of the compression spring 25. In this process, the latch head 19 pivots about the bearing pin 24, whereby the stop 27 moves away from the counter-stop 28.

[0026] When the bin lid is closed, the locking pin 20 slides along the ramp 32 of the hook 4. Simultaneously, the latch head 19 pivots relative to the control arm 17, and during this movement, the stop 27 releases from the counter-stop 28 as a result of compression by the compression spring 25. The latch head 19 is then pivoted back into the locked position by the relaxing compression spring 25.

[0027] In this embodiment, the catch hook 4 is a plastic hook formed from the same material as the counter-locking housing 3. However, it is also possible for the hook 4 to be formed from a metal part that is permanently attached to the counter-locking housing 3.

[0028] In the embodiment described above, an internal emergency operation is possible. For this purpose, an actuating flag can be arranged either on the actuating arm 30 or on the working arm 31, with which the opening aid 22 can be pivoted in order to pivot the latch head 19 into the release position.

[0029] It is also possible to provide means that are assigned to the lock housing 1 and with which the latch head 19 can be pivoted relative to the control arm 17 in order to disengage the hook connection.

[0030] The trap head 19 can also be elastically pivoted to the control arm 17 by other means. For example, this can be achieved using a spring element in the form of a leaf spring. In this variant, the leaf spring possesses the required stiffness and connects the trap head 19 to the control arm 17. In the Fig. In the second embodiment shown in Figures 8 to 10b, the weight element 5 can also interact with the control arm 17 in a different way. For example, the weight element 5 can be pivotally arranged in the lock housing. The opening aid does not necessarily have to be in the form of a rocker, although the latter has proven advantageous. To push the latch head 19 away from the bolt, the opening aid can also be designed as a slide.

[0031] From the Fig. Figure 10a shows that the control pin 16 is located approximately halfway along the length of the control arm 17. It has a diameter that is significantly smaller than the width of the control slot 15. At the end of the control arm 17 is a retaining pin 33, which engages in a retaining recess 34 of the opening slide 5. In this position, torques applied to the control arm 17 are transmitted via the retaining pin 33 into the wall of the retaining recess 34. When a torque is applied to pivot the latch head 19, the control pin 16 does not contact a wall of the control slot 15.

[0032] In the Fig. Figure 11 shows the semicircular latch 8 in a locked position. The locking bar 14 is undercut here. Behind the housing-fixed locking bar 14 is a clearance 35. A retaining projection 36 of the misoperation locking element 8 can engage in this clearance 35. For engagement, a slight relative displacement of the weight 5 with respect to the lock housing 1 in its direction of movement is required. Due to this interlock, the misoperation locking element 8, once in the locked position, cannot be dislodged by shocks or vibrations. If the weight 5 were to be displaced slightly with the misoperation locking element 8 in the released position, the locking bar 14 would act as intended by the Fig. Figure 12 shows the entry barrier of the holding projection 36 into the open space 35.

[0033] The Fig. Figure 13 shows the single-armed misoperation locking element 7 in a latched position. Here, too, there is a clearance 37 behind the locking bar 13, into which a hook projection 39 of the misoperation locking element 7 can engage. For this purpose, the misoperation locking element 7 is slidably mounted within the recess 11. In the Fig. In the position shown in 14, the misuse locking element 8 cannot enter the locked position because the locking end, i.e., the hook projection 39, lies in front of a stop 44. Only a displacement of the misuse locking element 7 from the position shown in Fig.The position shown in Figure 14 to the right allows pivoting into the free space 37. To enable this linear displacement of the locking element 7, the bearing axis 9 lies in a larger-dimensioned bearing shaft 41, which is bounded by a limiting web 42. On the side of the bearing shaft 41 opposite the limiting web 42 is a chamber 43 into which a short arm 40 of the misoperation locking element 7 projects.

[0034] Following the aforementioned linear displacement of the misoperation locking element 7 to the right, it can pivot into the free space 37. A subsequent displacement of the opening slide 5 causes the locking bar 13 to enter the claw opening 38, which is located behind the hook projection 39. From this position, the misoperation locking element 7 cannot be dislodged by shocks or vibrations.

[0035] All disclosed features are (in themselves) essential to the invention. The disclosure of this application also incorporates in full the disclosure content of the associated / attached priority documents (copy of the earlier application), also for the purpose of including features of these documents in the claims of the present application.
