Description

Description Lock, especially bin lock field of technology

[0001] The invention relates to a lock, in particular a bin lock, comprising a lock housing, a locking part, a locking counterpart, and a locking weight, wherein the locking part is displaceable between a release position and a locked position and interacts with the locking counterpart in the locked state, wherein the locking weight is displaceable in the lock housing on a movement path in a displacement direction due to gravity between a first and a second end position, and wherein furthermore, two cam tracks are provided on a cam track part, a first cam track and a second cam track, which cam tracks interact with the locking part under the influence of the locking weight to move the locking part between the locked position and the release position via a cam counterpart formed on the locking part.

[0002] Furthermore, the invention relates to a garbage can with a garbage can lock, wherein the garbage can has a lid and a can body with a can wall, wherein the garbage can lock has a first lock part attached to the can wall and a second lock part attached to the lid, wherein the first lock part has a lock housing, a locking part and a locking weight and the second lock part has a locking counterpart, wherein the locking part is displaceable between a locked position and a release position and interacts with the locking counterpart in the locked position, wherein the locking weight in the lock housing is on a path of movement in a displacement direction due to gravity between a first and a second The end position can be moved and interacts with the locking part for movement between the locked position and the release position via a sliding track. State of the art

[0003] Garbage cans of the type in question are known. These essentially consist of a can body with a surrounding wall and a base, as well as a lid that, in its normal state of use, pivots about a geometric pivot axis running essentially in a horizontal plane. In the closed position, the lid seals the opening of the can defined by the wall. To ensure that access, for example, for emptying household waste into the garbage can, is restricted to authorized persons, it is also known to equip such a garbage can with a suitable lock. When locked, this lock prevents the lid from being opened relative to the container.However, when emptying the garbage can, for example by means of a standard emptying vehicle, it should be possible to automatically open the lock to allow the lid to swing into the open position when the garbage can is tipped into an essentially upside-down position.

[0004] From DE 10 2007038 351 Al, DE 102015 113853 Al and DE 202022 130873 All are known to be waste bin locks. The locking devices described therein have a latch which, via a cam track formed in a locking weight, into which a cam pin of the latch engages, can be pivotally displaced from a closed position to the open position and vice versa as a result of a gravity-induced displacement of the locking weight. The latch interacts with a catch hook provided on the container lid. Summary of the invention

[0005] The invention is based on the objective of advantageously further developing a lock of the generic type. Furthermore, it aims to advantageously develop a waste bin of the type in question.

[0006] According to a first inventive concept, one possible solution to the problem is given in a lock in which the locking weight is displaceable in the direction of displacement relative to the cam track part.

[0007] The locking weight and the cam track component can, preferably, be manufactured as two separate parts, which results in particularly advantageous production. For example, the locking weight can be made of a different material, such as a material with a higher specific gravity than the cam track component, which has a lower specific gravity. Furthermore, by selecting an appropriate material for the cam track component, the design of the cam tracks, and for example their surface finish, can be simplified.

[0008] By enabling a displacement of the locking weight relative to the cam track part, an advantageous force can be applied to the cam track part via the locking weight to move the locking part via the cam track, which is effective depending on the displacement direction, into the locked position or into the released position.

[0009] According to a further inventive idea, for the advantageous design of the castle, it can be provided that the scenery track part is mounted on a The relocation area is relocatable and the scenery tracks are designed in such a way that they extend along their length at different distances to the relocation area.

[0010] The displacement surface of the cam track section can be designed as a flat, sliding plane. With respect to this displacement surface, the cam tracks, which appear as lines in a cross-sectional view (vertical with respect to the usual operating position), run at a preferably acute angle, resulting in a displacement of the locking element, which is controlled via the cam tracks, in an approximately perpendicular orientation to the displacement surface. The lock is preferably used as a garbage can lock. The garbage can has an open top. The upper opening is closed with a lid. In the usual operating position, the can opening points vertically upwards, and the lock is attached to a can wall near the opening such that the movement path of the one or more locking weights is vertical.A locking element prevents a locking counterpart attached to the barrel lid from being moved vertically upwards.

[0011] A trackway can have a control surface with a length and a width measured perpendicular to it. A trackway can also be purely linear, for example in the form of a ridge.

[0012] The cam tracks can be formed one behind the other in the displacement direction of the locking weight, whereby, viewed in the displacement direction, only the second cam track is formed over a second subsection of the cam track part.

[0013] With reference to the usual position of use of the castle, in which the direction of relocation is oriented along a vertical axis, a partial overlap may occur when both linear scenery tracks are projected onto a common vertical surface and then further projected horizontally from this projection onto the relocation surface. For example, in this projection, the second scenery track may only be partially reflected in the first, while the first scenery track may be completely reflected in the second.

[0014] In a further embodiment, the two cam tracks can also be combined with the previously described design by spacing them apart in one direction perpendicular to the direction of displacement and, preferably, by not overlapping when viewed in the direction of displacement. In such a design, the cam counterpart can be provided with cam counterpart sections that are designed to interact either with the first cam track or with the second cam track.

[0015] An advantageous further development of a waste bin of the same type can be achieved by the fact that the closing weight moves the closing part away from the bin wall to move into the closed position and pulls it towards the bin wall to move into the release position.

[0016] Accordingly, the direction of movement of the locking part can result in a direction that is essentially oriented along a horizontal axis, with reference to the usual usage and placement situation of the garbage can.

[0017] The locking mechanism can be operated via a lock housing facing the inside of the waste bin and away from the bin wall. The end plate protrudes from the front wall to interact with the second lock part on the cover side. When the locking element moves into the release position, the movement described above causes it to protrude less than it would in the locked position, extending beyond the front wall of the lock housing. This protruding end of the locking element can then be conveniently used for emergency unlocking from the inside by pressing it towards the interior of the lock in its usual direction of movement, thereby releasing the locking counterpart of the second lock part on the cover side.

[0018] The features of the aforementioned independent claims are both essential in themselves and significant in every combination with each other, wherein features of one independent claim can be combined with the features of another independent claim or with features of several independent claims, and furthermore also with only individual features of one or more of the further independent claims.

[0019] For example, the locking weight can be displaceable in the direction of displacement relative to the cam track section, and the cam tracks can be formed one behind the other in the direction of displacement of the locking weight, and in addition, only the first cam track can be formed over a first section of the cam track section and only the second cam track can be formed over a second section of the cam track section in the direction of displacement.

[0020] For example, a waste bin can be designed in which the locking weight moves the locking part away from the bin wall to the locked position and to the release position. lung towards the barrel wall, wherein the closing weight can be displaceable in the direction of displacement relative to the cam track part and / or wherein the cam tracks can be formed one behind the other in the direction of displacement of the closing weight, wherein in addition, in the direction of displacement only the first cam track and only the second cam track can be formed over a first section of the cam track part and over a second section of the cam track part.

[0021] Further features are explained below, also in the figure description, often in their preferred relation to the generally described solution and / or solutions, or to other features. However, they may also be related to only individual features already described, to the respective feature described further, or be independent of their significance.

[0022] According to a possible further development, the cam track component can be mounted in the lock housing so that it is displaceable to a limited extent in the direction of displacement. Preferably, both the locking weight and the cam track component are each displaceable to a limited extent in the direction of displacement, whereby, at least in one possible end position of displacement, the locking weight and the cam track component can abut each other.

[0023] In an advantageous further development, the locking weight is mounted in the cam track section and is displaceable relative to the cam track section in the direction of displacement. Accordingly, for example, in a stop-limited end position of the locking weight against an associated stop wall of the cam track section, a further common displacement- The movement of the cam track section in the direction of displacement takes place together with the closing weight.

[0024] Furthermore, the cam track section can interact with the cam counterpart of the locking element via the first cam track to move the locking element into the locked position and via the second cam track to move the locking element into the unlocked position. The respective cam track can also control the adjacent cam counterpart, in particular the adjacent cam counterpart section, to correspondingly displace the locking element.

[0025] In one possible configuration, the first and second scenery tracks can form essentially the same acute angles to the relocation surface. However, in a preferred configuration, these angles are chosen to be of different sizes.

[0026] For example, in a section where both scenery tracks are represented as lines, the first scenery track can form a larger angle with the displacement surface than the second scenery track. This larger angle value can be, for example, 1.2 to 2 times, or even approximately 1.5 times, the angle value of the second track.

[0027] The lock housing may also contain two locking weights: a first locking weight, which is slidably mounted in the cam track section, for example as the so-called main weight, and a second locking weight, a so-called hammer weight, which may be located outside the cam track section.

[0028] According to one possible design, the first locking weight (main weight) can also consist of two individual weights that are independently movable within the cam track section.

[0029] The first locking weight compresses the cam track section downwards in its normal operating position, forcing the locking element into the first displacement position via the first cam track. The second locking weight may be dragged along with the cam track section into this lower position.

[0030] When the garbage can is tilted, and consequently the lock is also tilted from its usual position towards an almost upside-down position, the cam track section is forced towards a second displacement position by the first locking weight acting upon it after a relative displacement within the cam track section. In this second displacement position, the second cam track engages with the counterpart of the locking element. Subsequently, or possibly superimposed upon, this weight displacement, the second locking weight shifts, imparting a further hammer-like impulse to the cam track section, directly impacting the cam track section or indirectly impacting the first locking weight. The locking element is then pulled into the release position by the counterpart of the second cam track, which interacts with it during this displacement.

[0031] The second locking weight can be displaced in the direction of displacement both relative to the cam track part and relative to the first locking weight in the lock housing.

[0032] The lock thus has at least two, preferably three, independently movable mass bodies, namely a cam track part, at least one first locking weight in which two preferably independently movable mass bodies are provided and a second locking weight that can directly act upon the first locking weight.

[0033] The locking element can be designed as a locking hook. Such a locking hook can, for example, catch a bar-like locking mechanism attached to a garbage can lid, thus preventing theft.

[0034] In a further embodiment, the locking element or locking hook can be pivotally mounted in the lock housing in a manner similar to a rotary latch. The corresponding geometric pivot axis preferably runs transversely to a depth dimension resulting between the end wall and the opposite rear wall of the lock housing and, more preferably, perpendicular to the direction of displacement.

[0035] Furthermore, the locking element can, for example, capture a pivot pin on the lock housing side by means of an elongated recess, which, in addition to the pivoting displacement of the locking element described above, can also achieve a linear displacement of the locking element - possibly superimposed on this.

[0036] In a further possible embodiment, a catch bar can be formed on the lock housing. Such a catch bar can prevent the material, which is displaced towards the lock during a closing swing movement of, for example, a lid, or a garbage can lid, from moving towards the lock. The closing opposite is directed specifically towards the preferably hook-shaped free end of the closure part.

[0037] The catch bar can be U-shaped. One U-shaped section of the catch bar can extend horizontally in its normal operating position. Two U-shaped legs connected to the U-shaped section run parallel to each other. The free ends of the U-shaped legs are attached to the lock housing in such a way that an upward-facing gap or space is formed between the catch bar and the lock housing, into which the locking element engages in the locked position. The lock housing can be attached to the barrel wall by means of a collar, in particular a mounting collar. The mounting collar can form a cover part which has two parallel longitudinal slots through which the free ends of the U-shaped legs extend. The free ends are attached to the lock housing.Preferably, the free ends lie in a clamping position between a lock base body of the lock housing and the cover part, the lock base body forming grooves in which the bent free ends of the catch can be inserted.

[0038] The locking counterpart can be pivotally mounted for improved interaction with the locking element. Furthermore, the pivoting motion of the preferably shackle-shaped locking counterpart can be limited. A pivoting position of the locking counterpart can also be locked.

Description of the embodiments

[0040] The lock 1, shown for example in Figures 3 to 5, can be attached to a garbage can 2 as a garbage can lock. A first lock part 3 of the lock 1 is arranged, in particular, on the inside of a surrounding can wall 4, close to the edge of a can opening 5 which, in its usual state of use, as shown for example in Figures 1 to 17, is directed upwards.

[0041] To empty the waste bin 2 by tilting it into an almost upside-down position as shown in Figure 18, recesses 10 can be formed on the outer wall into which grippers 11, for example of a waste collection vehicle W, can be inserted (shown in the drawings only as dashed lines). However, other means are also possible by which the waste bin can be gripped by a waste collection vehicle's gripper.

[0042] As further shown, two such first lock parts 3 can be arranged on the same barrel wall 4. A barrel lid 7 is hinged to the edge of the barrel wall 6 opposite the barrel wall 4 that corresponds to the barrel opening 5, and the barrel opening 5 can be closed by means of this lid. The barrel lid 7 is provided with two bow-shaped locking counterparts 8 as second lock parts 9 for locking interaction with the respective first lock part 3.

[0043] Each lock 1 therefore preferably consists essentially of a first, container-side lock part 3 and a second, lid-side lock part 9.

[0044] The first lock part 3 can be held on the barrel wall 4 by means of a plate-shaped fastening unit 12 arranged on the outside of the barrel wall 4. Fastening screws 13 pass through overlapping bores in the fastening unit 12, the barrel wall 4, and in fastening lugs 15 of a possibly provided mounting sleeve 62, which surrounds the lock housing 14 on the inside of the barrel.

[0045] A locking cylinder 52 can also be provided on the mounting unit 12, which can be operated from the outside using a key 57. The locking cylinder 52 allows the locking counterpart 8 to be manually unlocked, enabling the barrel lid 7 to be swung open, for example, for filling. Due to the requirement of a key 57 that fits the locking cylinder 52, such manual unlocking is only permitted to authorized persons. Instead of a key 57, the lock can also have a handle or similar feature for manual unlocking. A triangular or square profile can also be provided for operating the locking cylinder instead of a key.

[0046] The lock 1, in particular the first lock part 3 on the side facing the bin, is further designed such that, during the proper emptying of the waste bin, the bin lid 7 swings open without actuating the locking cylinder 52. Simply moving the waste bin 2 into an almost upside-down position is sufficient to unlock the lock 1.

[0047] The lock housing 14 initially contains a linearly displaceable cam track section 16. This has two chambers 17, each for receiving a first locking weight 18. The two first locking weights 18 form a main weight.

[0048] The first locking weights 18 are in the chambers 17 in a displacement direction r or r z The first shutter weight 18 is movably mounted relative to the cam track section 16. Each first shutter weight 18 is longitudinally aligned in the previously described displacement direction r, r z given.

[0049] Perpendicular to the direction of displacement r, r z The first locking weight 18 is guided by chamber side walls 19. The displacement of the first locking weight 18 within the chamber 17 is limited by a chamber floor wall 20 and a chamber ceiling wall 21. The first locking weight 18 can be displaced on a flat chamber sliding base 27 relative to the cam track section 16. The chamber 17 is open on the side facing away from this chamber sliding base 27. The resulting chamber opening 28 is covered by a rear wall 23 of the lock housing 14 in the normal operating state.

[0050] It can shift in the direction of displacement r, r z a maximum displacement path b of the first closure weight 18 in the associated chamber 17, which is approximately 0.2 to 0.5 times, and further, for example, approximately 0.3 times, the displacement path r, r zThe length dimension a of the first locking weight 18 can correspond to the considered length dimension. Furthermore, this maximum displacement dimension b can be approximately 6 to 12 mm, preferably approximately 10 mm. However, the maximum displacement dimensions can also deviate from this.

[0051] In the usual operating position, the first closing weight 18, as well as the cam track part 16, has a displacement direction r, r' oriented along a vertical. The edge surface of the chambers 17 facing away from the chamber sliding base 27 preferably defines a displacement surface 49 of the cam track part 16.

[0052] The lock housing 14 has an end wall 22 facing towards the interior of the waste container 2 and a rear wall 23 that runs essentially parallel to it and at a distance from it. The first lock part 3 rests against the inner surface of the container wall 4 with its rear wall 23. Between the end wall 22 and the rear wall 23, a housing depth T is obtained, as seen in a section perpendicular to the rear wall 23 according to Figure 8.

[0053] As can be seen, for example, in Figures 5 and 6, the scenery track section 16 is essentially L-shaped with respect to a ground plan, with the two parallel and spaced-apart U-shaped legs 24 forming the chambers 17. A U-shaped web 25 running in the area of ​​the chamber ceiling walls 21 and connecting the U-shaped legs 24 forms a first scenery track 26.

[0054] In particular, the first cam track 26 is formed on a thickening 29 extending from the U-bridge 25 and projecting into the free space between the U-legs 24, wherein the first cam track 26 is further preferably located on a side of the thickening 29 that is essentially facing away from the chamber opening 28 and towards the chamber sliding floor 27.

[0055] The control surface 30 of the first scenery track 26 closes in a cross-section through the first castle part 3, in which cross-section the publishers- The control surface 49 is represented as a line (compare Figure 10), forming an acute angle a of, for example, about 45 degrees to the displacement surface 49 of the cam track part 16, whereby the control surface 30 rises from the end region facing the chamber sliding floor 27 to the end region facing the chamber opening 28 and thus extends over a length 1 of the first cam track 26 from a larger distance c considered perpendicular to the displacement surface 49 to a smaller distance c', which can ultimately also be zero (compare Figure 10).

[0056] On the mutually facing surfaces of the inner chamber side walls 19, a second cam track 31 is further formed on the cam track section 16. This results from two control surfaces 32, which are assigned to the chamber side walls 19 in a rib-like manner and which leave a free space 33 between them extending from the thickening 29 or from the first cam track 26 to the free ends of the U-shaped legs 24.

[0057] The control surfaces 32 form a smaller angle β with the displacement surface 49 compared to the control surfaces 30, for example, an acute angle β of approximately 30 degrees. Thus, the control surfaces 32 of the second cam track 31 can extend from a larger distance d perpendicular to the displacement surface 49 over the length 1' of the second cam track 31 to a smaller distance d', which can ultimately also be zero (see also Figure 10).

[0058] In a projection of the cam trackways 26 and 31 or their control surfaces 30 and 32 in the direction of the housing depth T into a common projection surface, there is preferably no overlap of the control surfaces 30 and 32. Rather, they extend side by side, spaced apart from each other.

[0059] In the case of a projection of the scenery tracks 26 and 31 onto a common vertical surface, in which the control surfaces 30 and 32 as well as the displacement direction r and r respectively are located, it is also possible for the control surfaces 30 and 32 as well as the displacement direction r and r respectively to be located. z Represented as lines, an upper section S of the scenery track section 16 is formed, in which, in a further projection of the scenery tracks 26 and 31 onto the displacement area 49, an overlap of the first scenery track 26 with a section of the second scenery track 31 is formed. A further lower section S z However, it only has a section of the second scenery track 31.

[0060] The control surface 30 can be positioned on the underside of the thickening 29 in a direction that is essentially oriented in the displacement direction r, r z extending support surface 34.

[0061] The cam track section 16 with the cam tracks 26 and 31 serves to control a steep locking mechanism 35 in the first lock section 3. The locking mechanism 35 is essentially fork-shaped, with two transverse sections r, r to the displacement direction. z The fork legs 36, which are parallel to each other and spaced apart, and preferably of the same shape, are pivotally mounted in the area of ​​the free ends by an axle 38 that passes through elongated recesses 37 in the fork legs 36. The axle 38 is part of the housing 14.

[0062] At the end opposite the pivoting bracket described above, the locking element 35 forms a locking hook 39. This hook, preferably in both the release position and the locking position described below, passes through an opening 40 in the area of ​​a cuff 61 embedded in the housing end wall 22. The locking element 35 can be formed in multiple parts or as a single piece with the locking hook 39.

[0063] Further towards the end of the fork legs 36 facing the locking hook, the locking part 35 is provided with a cam-type counterpart 41. In the illustrated embodiment, this is designed in a wave-like manner and extends transversely to the surface extensions of the fork legs 36 and correspondingly transversely to the housing depth T, passing through the fork legs 36 in appropriately positioned bores.

[0064] The wave-like cam-like counterpart 41 extends freely on both sides beyond the opposite broad surfaces of the fork legs 36, forming second wave segments 43 there. In addition, the cam-like counterpart 41 also bridges the free space resulting between the opposing broad surfaces of the fork legs 36, forming a first wave segment 42.

[0065] The first, corresponding middle wave section 42 of the cam opposite 41 can, as shown, be larger in diameter - for example by about 1.5 to 3 times - than the outer, second wave sections 43.

[0066] The first wave section 42 serves for controlling interaction with the control surface 30 of the first cam track 26 of the cam track section 16 and the second wave sections 43 for interaction with the control surfaces 32 of the second cam track 31.

[0067] Part of the first lock section 3 is a second locking weight 44 (hammer weight), which is also displaceable in the direction of displacement r, r' relative to the cam track section 16 within the lock housing 14. The second locking weight 44 surrounds the cam track section 16 in a frame-like manner and has a corresponding orientation in the usual operating position of the first The lock section consists of three upper frame bolts 45 and one lower frame bolt 46, which are connected to each other via laterally extending frame posts 47. The frame posts 47 support laterally projecting, weight-increasing sash sections 48.

[0068] Both locking weights 18 and 44 are preferably made of a material with a significantly higher specific gravity, particularly compared to the cam track part 16. Furthermore, the locking weights are preferably metal parts.

[0069] As shown, the second locking weight 44 can also have a weight-receiving part 59 (Fig. 5), which, like the cam track part 16, can be made of a plastic material. In the weight-receiving part 59, recesses 60 are formed in the area of ​​the wing sections 48, into which circumferentially shaped weight inserts 58 are received. The weight inserts 58 are preferably metal parts.

[0070] The first lock part 3 is further provided with a catch bar 50 that penetrates the end wall 22 of the lock housing 14 and, in the operating position, is directed towards the interior of the waste container 2. The catch bar 50 is essentially U-shaped, with the free ends of the U-legs being fixed inside the lock housing 14. The U-rib 50" runs perpendicular to the U-legs. The catch bar 50 can be made of thick wire with a round cross-section. The U-legs 50' pass through a preferably elongated opening 66 of a cover part formed by the retaining sleeve 62 and run along the rear side 62' of the cover part in a recess 67, which in the embodiment shown is a groove adapted to the cross-section of the U-leg 50'. The The recess 67 is formed by the lock housing 14. The recess extends along an arc-shaped path, so that an angled end section 68 is clamped between the lock housing 14 and the cover 62.

[0071] The locking hook 39 of the locking part 35 projects towards the space enclosed by the U-legs and the U-bridge.

[0072] The locking counterpart 8 of the second lock part 9 can also be essentially U-shaped, with the free ends of the U-shaped legs being held in bases 51 attached to the underside of the barrel lid 7. The holder can be designed such that a limited pivoting movement of the locking counterpart 8 around the angle e in Figure 2, transverse to the extension of the U-shaped web, is possible (see double arrow e in Figure 2).

[0073] Figure 2 shows a typical position in use of a previously described lock 1 when attached to a garbage can 2. The can wall 4 holding the first lock part 3 is essentially vertically oriented, which, according to the described arrangement of the first lock part 3 on the can wall 4, also results in a vertical orientation of the displacement surface 49 (see Figure 8).

[0074] In the basic orientation shown in Figures 2, 3, 7 to 11, the barrel lid 7 is locked in the closed position by the lock 1. The shackle-like locking counterpart 8 of the second lock part 9 is received in the space between the catch 50 and the end wall 22 of the lock housing 14 and is engaged there by the locking hook 39 of the locking part 35 in a trap-like manner. The barrel lid 7 is thus prevented from being swung open into the open position.

[0075] To allow an authorized user to swing open the bin lid 7 from this locked basic position, for example to dispose of waste in the garbage bin 2, the user can operate the locking cylinder 52 using a suitable key 57. Alternative methods for opening the bin lid 7 may also be provided; for example, a handle operation may be provided that allows the lock to be moved into a release position.

[0076] According to the illustrations, when the cylinder core is rotated, a toothed ring 53 can be driven by the locking cylinder 52. This toothed ring acts on a correspondingly toothed, curved control finger 54. At its free end, the control finger 54 loads a cantilever 55 of the cam track section 16, which extends in line with a chamber 17. As a result of this load, the cam track section 16, with the first locking weights 18 located in the chambers 17, is linearly displaced vertically upwards against gravity in the displacement direction r along the displacement surface 49.

[0077] As a result of the placement of the upper frame bar 45 of the second locking weight 44 on the associated surface of the chamber ceiling wall 21 of the cam track part 16, the second locking weight 44 is dragged along during this displacement of the cam track part 16 controlled via the locking cylinder 52.

[0078] A corresponding displacement dimension f of, for example, 30 to 45 mm, or further, for example, approximately 38 mm, may result.

[0079] As a result of this relocation of the cam track section 16, the interaction of the second wave section 43 of the cladding part- The soapy cam counterpart 41, together with the second cam track 31 of the cam track part 16, moves the locking part 35 with its locking hook 39 from the locked position according to Figure 8 back towards the lock housing 14 into the release position (see Figure 14). The bow-shaped locking counterpart 8 of the second lock part 9 is released, so that the barrel lid 7 can be pivoted open about its pivot axis x.

[0080] As an alternative to the toothed ring design described above, a locking bar-like extension can also be provided on the locking cylinder, which engages the cam track section 16 via a link to move it. However, an alternative is also conceivable in which a trigger engages directly on the locking part 35 to move it towards the barrel wall 6.

[0081] As the locking cylinder 52 rotates back to its starting position, the cam track section 16 is also moved by gravity, via the acting weights of the first and second locking weights 18 and 44, into the vertically lower stop position, which corresponds to the basic orientation. During the lowering movement of the cam track section 16, the locking part 35 is pivoted back into its closed position as shown in Figure 15 by means of the first cam track 26 via the first shaft section 42, in which the locking hook 39 projects in a locking manner into the pivoting path of the locking counterpart 8.

[0082] From the open position of the barrel lid 7, it can be closed and locked even without operating the locking cylinder 52. For this purpose, the barrel lid 7 with the second lock part 9 is pivoted towards the first lock part 3. In the course of the downward pivoting movement of the barrel lid 7, the bar-shaped locking counterpart 8 can be engaged. if necessary, be directed by the catch 50 of the first lock part 3 towards the locking part 35.

[0083] The locking hook 39 of the locking element 35, which again projects into the closed position, is acted upon from above by the bow-shaped locking counterpart 8 during the downward pivoting movement of the barrel lid 7. This action causes the locking element to be forced towards the interior of the housing by a control ramp 56 provided on this actuation surface. In this process, the first shaft section 42 of the cam counterpart 41 slides off the facing first cam track 26 and, via this track, forces the cam track part 16 into a raised position against the gravity-dependent restoring force of the locking weights 18 and 44 acting on the cam track part 16. This raised position allows the locking element 35 to pivot into the release position.

[0084] The locking hook 39 can be overridden by the locking counterpart 8, whereby, due to the lack of load on the locking part 35, the cam track part 16 is displaced towards its basic orientation in the displacement direction r' by the acting weight forces via the locking counterpart 8. This re-displacement of the cam track part 16 causes the locking part 35 to be guided into the closed position due to the interaction of the second shaft section 43 and the second cam track 31, whereby the locking counterpart 8 is finally locked again against the lowering movement of the barrel lid 7.

[0085] In the same manner as described above, during the closing pivoting movement of the bin lid 7 and the resulting forced control of the locking element 35 into the release position, a manual emergency release can also be carried out from inside the waste bin 2. The area of ​​the The locking hook 39, which is exposed at least on the end faces of the bow-shaped locking counterpart 8 and the catch 50, can be moved towards the release position by pressure in the direction of arrow g (see Figure 8), thereby releasing the locking counterpart 8 to open the barrel lid 7. When the pressure in the direction of arrow g is removed, the cam track part 16 also falls back, due to gravity, into its basic orientation, which forces the locking part 35 into the closed position.

[0086] For the usual emptying of the waste bin 2, it is advantageous from a handling perspective that no operation of the locking cylinder 52 is necessary. Rather, the usual handling for emptying the waste bin 2 is sufficient to move the locking part 35 into the release position that releases the locking counterpart 8.

[0087] The waste bin 2 is lifted, preferably via the grippers 11 of a waste disposal vehicle W projecting into the receptacles 10, and pivoted about a tilting axis y running essentially parallel to the pivot axis x of the bin lid 7 over a loading opening of the waste disposal vehicle W (see Figures 18 to 27).

[0088] As part of this pivoting movement of the waste container 2, the container wall 4, together with the first locking part 3, leaves its essentially vertical orientation. With increasing pivoting movement, the container lid 7 pulls on the locking hook 39 of the locking part 35 via the locking counterpart 8, which thereby – as well as through manual action on the container lid 7 in the usual orientation – moves away from the first cam track 26 into a support position on the facing support surface 34 of the thickening 29 by a (stop-limited) dimension h of, for example, approximately 6 to 10 mm, and further, for example, approximately 8 mm. This situation can also occur if bin 2 is overloaded (see Figure 20).

[0089] Due to gravity, when the displacement surface 49 pivots beyond a horizontal plane towards an almost overhead position of the waste container 2, the first locking weights 18 within the chambers 17 are displaced. A first impulse to displace the cam track section 16 onto it can be introduced by means of stops on the chamber ceiling walls 21.

[0090] Following the displacement of the first locking weights 18 – or superimposed on this displacement – ​​a corresponding displacement in the displacement direction r of the second locking weight 44 also occurs, which imparts a further hammer-like impulse to the cam track section 16 and thus moves the cam track section 16 into the stop position corresponding to the release position, in which the previously described dimension h is also overcome. In doing so, the second locking weight 44, with its lower frame bar 46, passes over a section of the cam track section 16 thinned by a notch 63, so that ultimately a direct, impulse-generating impact of the second locking weight 44 with its lower frame bar 46 against the facing end faces 64 of the first locking weights 18 can be achieved.As a result of this hammer-like impulse, even with possible increased friction between the locking part 35 and the cam track part 16 and / or between the locking part 35 and the locking opposite 8, a displacement of the cam track part 16 and, via this, a displacement of the locking part 35 into the release position can be achieved.

[0091] A certain degree of interference between the locking hook 39 and the locking counterpart 8 can also arise from the fact that the garbage can 2 The mechanism is overloaded, meaning that a tensile force develops on the locking element 35 in its normal position. Consequently, the locking element 35 becomes difficult to move into the release position. It is also possible that, due to environmental influences, the individual moving parts 16, 18, and 44, namely the cam track 16, one or more first locking weights 18, or the second locking weight 44, become more difficult to move relative to one another. In this case, the individual moving parts 16, 18, and 44 can move sequentially in the direction of movement r, thereby transferring momentum to another moving part, thus overcoming increased friction between the locking element 35 and its counterpart 8.

[0092] During this preferably gravity-induced displacement of the cam track section 16, the interaction of the second shaft section 43 of the cam counterpart 41 and the second cam track 31 controls the locking element 35 with its locking hook 39 into the release position, whereby the locking element 35 is essentially pulled towards the barrel wall 4. The locking counterpart 8 is released and the barrel lid 7 can swing open due to gravity.

[0093] When the waste bin 2 is swung back into its usual operating position as shown in Figure 2 or 7, the locking weights 18 and 44 automatically shift due to gravity in the direction of displacement r' back into the vertically lowered position, dragging along the cam track section 16. Via the first cam track 26, in conjunction with the first shaft section 42, the locking part 35 is forced into the closed position, essentially resulting in a movement of the locking part 35 away from the bin wall 4.

[0094] Figures 29 to 39 show the essential elements of a further embodiment of the invention, in which in particular the locking cylinder 52 and the weights 58 have changed compared to the embodiment described above.

[0095] Within a lock housing 14 is the previously described locking element 35, which forms a locking hook 39 that, in a locked position, can engage a locking counterpart 8. The locking element 35 is mounted by a leg 36 around a pivot axis fixed to the housing. The pivot axis is located at the end of the leg 36 opposite the head of the locking element 35.

[0096] Inside the housing is a slide 16 which, when the lock housing 14 is turned upside down, can be moved from a closed position shown in Figure 31 to an open position shown in Figures 34 and 32. During this movement, a pin forming a cam counterpart 41 slides along an inclined cam track 31 of the slide 16. This draws the head of the locking part 35, which forms the locking hook 39, into the housing 14.

[0097] When the slide 16 is moved back to the home position shown in Figure 31, a further cam track 26 strikes a cam counterpart 41' of the locking element 35 in a final phase of this movement. Due to the inclined path of the cam track 26, the head of the locking element 35 is pivoted out of the housing into the closed position. The cam counterpart 41' is formed here by an edge of the leg 36.

[0098] Figure 32 shows the key-operated movement of the slide 16 from the closed to the open position. A control finger 35 with an arcuate control cam is located on the locking cylinder 52. This cam acts on a control shoulder 71 of the slide 16 to move the slide 44 upwards. The weights 18 arranged in the slide 16 are dragged along with it. Lateral wings 70 project from the slide 16, forming shoulders 70', 70". The shoulders 70" each engage projections 69 of another weight body 58, which is enclosed in a plastic casing 69. The casing 69 forms this projection 69" and a spaced-apart projection 69', the distance between the two projections 69', 69" being greater than the distance between the two shoulders 70', 70" of the wing 70.

[0099] If the lock is tilted, for example when emptying a garbage can to which the lock is attached, for example when turned upside down as shown in Figures 33 and 34, gravity acts on the weights 58 and 18, which are each located in a chamber 17 of the slide, and on the slide 16.

[0100] Depending on the frictional forces between the casing 69 and a sliding surface of the housing 14 or the slide 16 and an associated sliding surface of the housing 14 or the weights 18 and a sliding surface of the chamber 17, one of the five movable elements moves first.

[0101] In figure 33, the weights 58 contained in the casings 69 moved first, so that the projections 69' struck the shoulders 70' of the wings 70.

[0102] Since the projections 69" rest against the shoulders 70" in the home position, the weight 58 can shift relative to the wing 70 in the home position due to gravity, so that the projection 69' imparts an impulse to the shoulder 70'. This then leads to a movement of the slide 16. The weights 18 arranged in the chambers 17 of the slide 16 are dragged along with this movement.

[0103] If the movement of the slide 16 comes to a standstill, the weights 18 arranged in the slide 16 can become detached and shift in the chambers 17 under the influence of gravity until they strike an end wall of the chamber 17 and thereby impart an impulse to the slide 16 again.

[0104] It is therefore advantageous if two preferably paired weights 18, 58 can separately apply impulse to the slide 16 so that its cam tracks 31, 26 act on the locking part 35 in a movement-controlling manner, in order to bring the locking part 35 into the closed position with the help of the first cam track 26 and to bring the locking part 35 into the open position with the help of the second cam track 31.

[0105] In principle, it is sufficient if two weights 58 and 18, acting separately from one another, act upon the slide 16 forming the cam tracks 26, 31 when the lock housing is turned over, wherein one of these weights 58, preferably present in pairs, is mounted outside the slide 16 in the lock housing 14 and the other weight 18 is located inside the slide 16, for example in a chamber 17. The invention thus also relates to a lock with a locking element 35 which, in the mounted state of the lock, can be moved vertically between a closed position and an open position by means of a cam-controlled movement of a slide 16 arranged in the lock housing 14, wherein the slide engages one cam track 26 in each case. The lock has a cam track 31 for moving the locking part 35 into the closed position and a cam track 31 for moving the locking part 35 into the open position. The lock also has at least one weight 18, 58 coupled to the slide 16 with a play in its movement, which can move together with the slide 16, but due to this play, is able to impart an impulse to the slide 16 when the weight 18, 58 moves forward with a delay. Preferably, the lock has one weight 58 arranged outside the slide 16 and one weight 18 arranged inside the slide 16. Particularly preferably, the two weights 18, 58 are arranged in pairs.

[0106] Figures 29, 30, and 39 further show a base 51 for attaching the locking counterpart 8, which is formed by a wire clasp. The base 51 has a main body 72 with a cavity closed by a cap 73. In a region of a rounded rim extending over a 90-degree angle, the cap has several slots 47, each separated from the others by a rib 75. The locking counterpart 8 can be selectively received in the slots, allowing the angle of the locking counterpart 8 relative to the base 51 to be adjusted. An end section of the wire-formed locking counterpart 8 can be inserted into an opening in the main body 72 and pivoted around it.
