Receptacle with low friction and low noise motion damper for lid
First Claim
1. A trash receptacle configured to reduce audible noises during operation, said trash receptacle comprising:
- a body having an open top portion;
a lid, coupled to the body, configured to pivotably move between an open position and a closed position relative to the body;
an actuator, coupled to the lid, configured to move the lid via a linkage connected to the lid, wherein the linkage moves in response to an applied force; and
a dampening device comprising;
a movable component coupled to the linkage;
a graphite powder lubricant; and
a housing having an interior surface having at least one roughening surface feature,wherein the housing is infused with a foam material that disperses a lubricant when the movable component is actuated by the linkage, wherein the lubricant comprises a graphite powder, wherein the foam material is saturated with the lubricant, and wherein the lubricant trickles downward each time the dampening device is actuated, andwherein at least a portion of the movable component slides against the at least one roughening feature when the lid pivots between the open and the closed positions, the at least one roughening feature configured to reduce audible noise generated by the movable component sliding against the housing.

Abstract
A receptacle having a lid can be provided with a pair of dampers configured to slow the movement of the lid from its open position toward its closed position. The dampers can be provided at opposite ends of a pedal connected to the receptacle body at opposite lateral positions relative to a side of the receptacle body. In some embodiments, the damper is configured to be high endurance and low noise. For example, the damper may comprise lubricants, such as a graphite powder. The damper may also comprise a mechanism, such as foam infused with graphite powder, to disperse the lubricant over time. The damper may also employ surface features or noise dampening features in its housings to prevent or reduce noise.
