This invention relates to litter bins and more particularly to a litter bin having a gravity activated lock for a lid.
Litter bins are often used in outdoor environments and include a container defining an opening over which a lid is removably attached. Side openings in the lid and/or container permit people to throw away litter into the container. The lid must be removed to empty the litter bin. Some litter bins includes manually actuated latches to secure the lid to the container. This makes it more difficult to removed the lid and empty the litter bin. In particular, this makes it difficult for automated handling equipment to lift and empty the contents of the litter bins.
A litter bin according to the present invention includes a lid hingeably connected to a container. Opposite the hinge, a latch normally keeps the lid latched to the container. The latch is gravity-actuated, such that the lid is released when the litter bin is tilted sufficiently, thus making it easy to open the lid and empty the litter bin.
The latch includes a pivotably mounted latch member that has a center of gravity offset from its pivot point. The latch member also includes a catch portion that moves between a locked position and an unlocked position upon pivoting the latch member. Because the center of gravity of the latch member is offset from the pivot point, tilting the litter bin causes pivoting of the latch member, thereby moving the catch portion from the locked position to the unlocked position.
Because the latch is gravity-actuated, the lid is released automatically simply by tilting the litter bin while emptying it. Therefore, automated handling equipment need only lift and tilt the litter bin to empty it, without having to actuate the latch separately.
Other advantages of the present invention can be understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
A litter bin 10 is shown in
The lid 14 has a rearward end 32 opposite a forward end 34 that extends downwardly and mates with a column 20 extending upwardly from the container 12. The rearward end 32 of the lid 14 is connected to another column 20 of the container 12 via a hinge 36. As shown in
Referring to
The latch member 42 is pivotably mounted on pivot pin 44 within a recess 68 inside the column 20 of the container 12. The recess 68 includes an upper surface 66 for contact by the abutment member 60 to limit rotation of the latch member 68 in that direction. The recess 68 also includes a forward stop 69 below the shoulder 54 of the catch portion 50 and in front of the leg portion 58.
As can be seen in
The latch system 40 permits the lid 14 to be closed as shown in
To subsequently release the latch system 40, the litter bin 10 is tilted forward toward the latch system 40 as shown in
Because the latch system 40 is gravity-actuated, the lid 14 is released automatically simply by tilting the litter bin 10 while emptying it. Therefore, automated handling equipment need only lift and tilt the litter bin 10 to empty it, without having to actuate the latch system 40 separately.
While embodiments of the invention have been illustrated and described, it is not intended that these embodiments illustrate and describe all possible forms of the invention. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the invention. There are different designs of containers that would benefit from the present invention.
