Abstract
A locking/unlocking device for a waste collection container for automatically locking/unlocking, by gravity, the lid (2) of the container (1) on the vessel (4) of the container. A pivoting piece (8) is fixed in an articulated fashion to the internal face of the lid, and has a lever (8d) having a hook (9) engaging in an orifice (13) in the vessel; and an arm 8b) coming into engagement with a hook (7c) on an articulated angled piece (7). Tilting of the container (1) causes, by gravity effect, the pivoting of the angled piece (7) and then the pivoting of the pivoting piece (8) thus released from the hook (7c), towards an unlocked position. The device also relates to a container equipped with such a locking/unlocking device.
Claims17
A locking/unlocking device for a waste collection container, the container having a vessel and a lid associated with the vessel and movable between a closed position and an open position, the device enabling the lid of the container to be locked in a locking position on an end part of the vessel when the container is in a filling position, and to be unlocked when the vessel is in an emptying position, the device comprising a pivoting piece comprising:
- a lever fixed so as to be articulated on an internal face of the lid and projecting inside the container when the lid is in the closed position;
- an arm extending the articulation of the lever extending underneath the internal face of the lid when the lid is in the closed position;
- an intermediate part to which the lever and arm are fixed, through which an axis of rotation of the pivoting piece passes;
- wherein the lever has a retractable hook intended to be engaged in an orifice or hollow situated at the end part of the vessel, the arm having an end part, opposite to the intermediate part of the pivoting piece, coming into engagement with a hook forming part of an angled piece, the angled piece comprising a locking leg including the hook and a driving leg and being articulated on an axis of rotation parallel to the axis of rotation of the pivoting piece, the driving leg of the angled piece being locked in the locking position of the lid by a stop, whereby tilting of the container at a certain angle causes, the pivoting of the angled piece and the pivoting of the arm and of the lever towards an unlocked position;
- and
- wherein when the container is in the filling position, the centre of gravity of the angled piece holds the driving leg of the angled piece in abutment on the stop and the hook on the angled piece in engagement with the end part of the arm on the pivoting piece, the centre of gravity of an assembly comprising the pivoting piece and the hook being situated to hold the retractable hook on the lever in a position of engagement in the orifice or hollow in the end part of the vessel and the end part of the arm in engagement with the hook on the angled piece;
- the tilting of the container through the certain angle with respect to the vertical when it is emptied giving rise to a movement of the centers of gravity of the angled piece and of the assembly, causing a pivoting of the angled piece, releasing the hook on the angled piece from the end part of the arm on the pivoting piece, giving rise to the pivoting of the arm and of the lever and leading to the disengagement of the retractable hook from the orifice or hollow in the vessel and therefore to the opening of the lid of the container.

- a lever fixed so as to be articulated on an internal face of the lid and projecting inside the container when the lid is in the closed position;
- an arm extending the articulation of the lever extending underneath the internal face of the lid when the lid is in the closed position;
- an intermediate part to which the lever and arm are fixed, through which an axis of rotation of the pivoting piece passes;
- wherein the lever has a retractable hook intended to be engaged in an orifice or hollow situated at the end part of the vessel, the arm having an end part, opposite to the intermediate part of the pivoting piece, coming into engagement with a hook forming part of an angled piece, the angled piece comprising a locking leg including the hook and a driving leg and being articulated on an axis of rotation parallel to the axis of rotation of the pivoting piece, the driving leg of the angled piece being locked in the locking position of the lid by a stop, whereby tilting of the container at a certain angle causes, the pivoting of the angled piece and the pivoting of the arm and of the lever towards an unlocked position;
- and
- wherein the two legs of the angled piece are movable in rotation with respect to each other, about the axis of rotation of the angled piece and the driving leg of the angled piece comprises, towards its end part, a weight so that, when the container is tilted at a certain angle, the locking leg on the angled piece, which is still in engagement with the arm, the driving leg of the angled piece can pivot about its axis and then strike the hook so as to release the hook from the arm.
