Abstract

A receptacle having a lid which has a pair of dampers configured to slow the movement of the lid from an open position toward a closed position. The dampers are provided at opposite ends of a pedal connected to the receptacle body at opposite lateral positions relative to a side of the receptacle body. The receptacle includes an air filtration device mounted in its lid which guides air through the filter device during the downward motion of the lid. The receptacle also includes at least one damper which provides dampening forces against the motion of the lid in both opening and closing directions. The receptacle also includes an anti-sliding device which increases the receptacle'"'"'s resistance to sliding across a floor when a user steps on a pedal to actuate the lid.

Claims

1. A trash can, comprising:

a body comprising;

an outer sidewall defining an interior space and an open top,

a base portion defining a lower cavity and a sidewall, and

a lid hinged at the open top, the lid being pivotal between an open position and a closed position;

a pivot mechanism partially housed in the lower cavity of the base portion for operating the lid, the pivot mechanism comprising;

an exterior pedal disposed along the base portion, capable of pivoting the lid between the closed position and the open position, the exterior pedal having a first distal end and a second distal end;

a first pivoting joint connected to the first distal end of the exterior pedal, extending through the sidewall of the base portion and connected to a first end of a first interior lever

a second pivoting joint connected to the second distal end of the exterior pedal, extending through the sidewall of the base portion, and connected to a first end of a second interior lever

a first rod extending between a second end of the first interior lever and the lid;

a second rod extending between a second end of the second interior lever and the lid;

a first motion damper near the second end of the first interior lever; and

a second motion damper near the second end of the second interior lever, wherein the first and second dampers are configured to dampen motion of the first and second rods, respectively.

2. The trash can according to claim 1, wherein the first and second interior levers move with the exterior pedal as the exterior pedal moves between a resting position and an actuated position.

3. The trash can according to claim 1, wherein the first and second motion dampers are connected directly to the first and second interior levers, respectively, thereby connecting the first and second motion dampers to the first and second distal ends of the exterior pedal.

4. The trash can according to claim 1, wherein the first and second motion dampers are configured to provide approximately the same dampening forces against the movement of the lid from the open to the closed position.

5. The trash can according to claim 1, wherein at least the first motion damper is configured to provide dampening forces against the movement of the lid from the closed to the open position.

6. The trash can according to claim 1, wherein the exterior pedal is generally U-shaped.

7. The trash can according to claim 1, wherein the first and second motion dampers are separate from each other and mounted adjacent opposite sides of the body.
