Abstract
Description
[0001] The present invention relates to a waste collection device comprising a container having a container opening on its upper side, enclosed by a container rim, a lid held on the container which is pivotable about a lid pivot axis between a closed position closing the container opening and an open position releasing the container opening, and a locking device for locking the lid in the closed position, wherein the locking device comprises a locking element attached to the container rim and positioned below a through-opening extending through the container rim, and a housing attached to the lid by means of at least one fastening bolt, in which a lock and a pivot hook projecting downwards from the housing and extending through the through-opening in the closed position of the lid are received.which, in the closed position of the lid, can be pivoted by actuating the lock between a locked position, in which it is engaged with the locking element, and an unlocked position, in which it is not engaged with the locking element.
[0002] Such waste collection devices are known in the prior art in various configurations. For example, DE 44 07 690 A1 discloses a waste collection device with a container, a lid that closes the container and is pivotably held on it, and a locking device for locking the lid in the closed position to prevent unauthorized persons from filling the container with waste. In one embodiment, the locking device comprises a locking element in the form of a cylindrical pin, attached to the edge of the container and positioned below a through-opening extending through the edge of the container. The locking element is screwed to the container from the inside of the container wall.Furthermore, the locking device includes a lock attached to the lid, over which a pivot hook projecting downwards from the lid and extending through the through-opening in the closed position of the lid can be moved back and forth between a locking position, in which it engages with the cylinder pin, and an unlocking position, in which it does not engage with the cylinder pin.
[0003] Waste collection devices of the type described in DE 44 07 690 A1 have generally proven their worth in the past. However, a significant disadvantage is that their locking mechanism is unsuitable when the lid needs to be sealed to the container rim and, for this purpose, the lid is provided on its underside with a circumferential sealing groove in the area of its rim. An annular seal is inserted into this groove, which, when the lid is closed, rests tightly against the upper surface of the container rim. This is the case when the waste collection device is intended for the disposal of fats, oils, or other substances.The unsuitability of the known locking device is primarily due to the fact that the container, as well as the lid, must not be provided with through holes within the sealed volume, which is necessary in the arrangement disclosed in DE 44 07 690 A1 for fastening the locking element as well as for fastening the lock.
[0004] To address this problem, alternative locking devices have been proposed in the prior art that engage exclusively on the outside of the lid and container. For example, German patent applications DE 203 10 176 U1 and DE 20 2009 016 971 U1 propose lockable fastening brackets that grip the lid and container from the outside. However, a disadvantage of such bracket-like locking devices is their cumbersome handling, as they must always be removed to move the lid from the closed to the open position.
[0005] Further state of the art is represented by the publications DE 10 2004 007 862 A2, DE 42 03 810 A1 and EP 2 036 838 A1.
[0006] Based on this prior art, it is an object of the present invention to create a waste collection device of the type mentioned above with an alternative design which at least partially solves the problems mentioned above.
[0007] To solve this problem, the present invention provides a waste collection device according to claim 1. Thanks to the inventive extension of the at least one fastening bolt through the groove base of the sealing receiving groove, the housing, lock and pivot lever can be permanently attached to the lid without this fastening jeopardizing the tightness of the container volume sealed by the seal.
[0008] Preferably, the housing is attached to the side of the lid opposite the lid pivot axis, particularly in the center, thereby achieving the best locking effect.
[0009] Advantageously, the swivel hook is pre-tensioned towards the locking position by means of at least one spring element. Accordingly, the swivel hook automatically snaps back into its locking position as soon as the lock is no longer operated.
[0010] According to one embodiment of the present invention, the pivot hook is provided on its underside with a guide surface which is designed and positioned such that when its guide surface is placed on the locking element from above and the pivot hook is pressed further towards the locking element, it automatically moves into its unlocked position, whereupon the pivot hook then snaps back into the locking position due to the force of the spring element as soon as the pivot hook can engage in the locking element.
[0011] The locking element is preferably formed by a cylindrical pin, resulting in a simple and cost-effective design. The cylindrical pin is attached exclusively to the container rim. Accordingly, the attachment of the locking element does not compromise the tightness of the container volume sealed by the gasket.
[0012] Advantageously, a cover is provided, inserted into the bottom of the container rim, extending at least partially below the locking element and covering it from below, particularly in the form of a substantially U-shaped component, for example, a U-shaped bent sheet metal, with the cover preferably being attached to the locking element. Such a cover makes access to the locking element more difficult and thus prevents unauthorized manipulation of the locking device.
[0013] According to one embodiment of the present invention, the dimensions of the container rim, the lid, and the housing are selected such that, in the closed position of the lid, the housing does not project laterally beyond the container rim and / or that, in the closed position of the lid, the housing does not project upwards beyond the highest point of the lid. This effectively prevents the housing from obstructing the handling of the container or the lid, particularly during transport and / or emptying.
[0014] Furthermore, the present invention provides a locking device to solve the aforementioned problem, which is designed for the manufacture of a receiving device according to the invention.
[0015] Further features and advantages of the present invention will become clear from the following description of an embodiment of a receiving device according to the invention, with reference to the accompanying drawing. This drawing includes... Fig. 1 a perspective view of a waste collection device according to an embodiment of the present invention; Fig. 2 a front view of an area of the in Fig. 1 waste collection device shown, in which a locking device is arranged; Fig. 3 a sectional view along line III-III in Fig. 2; Fig. 4 a sectional view along line IV-IV in Fig. 2; Fig. 5 a front view of the locking device alone; Fig. 6 a side view of the Fig. 5 locking device shown; Fig. 7 A perspective top view of the locking device Fig. 8 a sectional view along line VIII-VIII in Fig. 7, which shows a locking position of a swivel hook; and Fig. 9 a sectional view analogous to Fig. 8, which shows an unlocked position of the swivel hook.
[0016] The receiving device 1 comprises a container 2, which has a container opening on its upper side framed by a container rim 3, a lid 4 held on the container 2, which is pivotally movable about a lid pivot axis 5 between a closed position (closing the container opening) and an open position (releasing the container opening), and a locking device 6 attached to the side of the lid opposite the lid pivot axis 5 for locking the lid 4 in the closed position. The lid 4 is provided on its underside, in the area of its lid rim, with a circumferential sealing groove 7 into which an annular seal 8 is inserted, which rests sealingly on the upper side of the container rim 3 in the closed position of the lid 4.The sealing groove 7 has a U-shaped cross-section, laterally bounded by an inner groove wall 9 into an outer groove wall 10 and upwardly by a groove base 11. When the lid 4 is closed, the inner groove wall 9 projects downward beyond the outer groove wall 10 and is positioned such that it enters the container opening when the lid 4 is closed, leaving a gap 12 between the outer surface of the inner groove wall 9 and the inner surface of the container outer wall 13. A downwardly projecting projection 14, extending along the inner circumference of the otherwise substantially rectangular seal 8, engages in this gap 12. The thickness S of this projection is adapted to the gap 12 such that the gap 12 is sealed when the lid 4 is closed.When the lid 4 is closed, the underside of the seal 8 is pressed against an upwardly projecting lip 15 on the container rim, further increasing the sealing effect. To generate the necessary contact pressure, the lid 4 is equipped with lateral, elastically movable, and manually operated hook elements 16, which can be engaged under the container rim 3 when the lid 4 is closed. This ensures a reliable seal of the container volume. Accordingly, the waste collection device 1 is suitable for collecting special types of waste, such as fats, oils, or other substances.
[0017] The locking device 6 serves to protect the waste collection device 1 from unauthorized access. The locking device 6 comprises a locking element 18, in this case in the form of a cylindrical pin, which is fixedly attached to the rim of the container 3 and positioned below a through-opening 17 extending downwards through the rim of the container 3. The locking element 18 is pressed into two aligned through-holes 19 from the outside. The first through-hole 19 is located in an outer wall 20 of the container rim, and the second through-hole 19 is located in a downwardly projecting rib 21 of the container rim, which extends between the outer wall 20 of the container rim and the outer wall 13 of the container. Accordingly, the tightness of the sealed container volume is not compromised by the arrangement of the locking element 18. The locking element 18 is covered from below by a cover 22.The cover 22 is formed by a substantially U-shaped component, in particular a U-shaped bent sheet metal, which is inserted into the container rim 3 from below such that its opposite side legs 23 extend adjacent to the inner surface of the outer wall 20 of the container rim on the one hand and to the outer surface of the outer wall 13 of the container on the other. The cover 22 is fixed to the locking element 18. In this case, the fixing is achieved during the assembly of the locking element 18 by guiding the locking element 18 through corresponding receiving openings 24 provided on the side legs 23 of the sheet metal already inserted into the container rim 3.The locking device 6 further comprises a housing 26, which is attached to the lid 4 by means of fastening bolts 25, in this case in the form of fastening screws. The housing contains a lock 27 and a pivot hook 29, which extends downwards through the bottom 28 of the housing and, in the closed position of the lid 4, extends from above through the opening 17 in the rim of the container 3. During the assembly of the locking device 6, the fastening bolts 25 are screwed in from below through the groove 11 of the sealing groove 7 and then covered with the seal 8. Accordingly, the tightness of the sealed container volume is in no way compromised by the fastening bolts 25.The pivot hook 29, when the cover 4 is closed, can be pivoted between a locked position, in which it engages the locking element 18, and an unlocked position, in which it does not engage the locking elements 18, by actuating the lock 27. The pivot hook 29 is biased towards its locked position by a spring element 30. More precisely, the pivot hook 29 comprises an actuating section located above its pivot axis 31 and a locking section located below the pivot axis 31. A bolt 32 of the lock 27 engages the actuating section, which, when actuated accordingly, moves the pivot hook 29 from the locked position to the unlocked position in the direction of arrow 33, as shown in the figures. Fig. 8 and Fig.Figure 9 shows that the locking section is provided with a recess 34 on its side facing the locking element 18, so that it can be moved in and out of engagement with the locking element 18 during a pivoting movement of the pivot hook 29. A guide surface 35 is provided on the underside of the pivot hook 29, which is designed and positioned such that when the pivot hook 29 is placed on top of the locking element 18 and the pivot hook 29 is pressed further towards the locking element 18, it automatically moves into its unlocked position, whereupon it snaps back into the locked position due to the force of the spring element 30 as soon as the recess 34 engages with the locking element 18.This is advantageous in that the lock 27 does not need to be actuated when closing the lid 4 in order to move the pivot hook 29 into the locking position, which significantly simplifies the handling of the locking device 6. The dimensions of the container rim 3, the lid 4, and the housing 26 are selected such that, in the closed position of the lid 4, the housing 26 does not project laterally beyond the container rim 3 or upwards beyond the highest point 36 of the lid 4. Thus, the housing 26 in no way obstructs the handling of the waste collection device 1, for example, during transport or emptying.
