Abstract

Various embodiments of a trash can assembly (e.g., a receptacle configured to receive refuse, recyclable materials, or otherwise), and related methods, are provided. Some embodiments of the trash can assembly include a body component and a lid configured to move between an open position and a closed position. In some variants, the lid can be moved between the open and closed positions by a power operated driving mechanism, such as a motor and/or other drivetrain components. In certain embodiments, the trash can assembly includes a clutch mechanism to facilitate manual operation of the lid while inhibiting or preventing damage to the motor and/or other drivetrain components.

16. The trash can assembly of claim 15, wherein, when the lid is moved between the opened and closed positions, the first and second inclined cam surfaces slide relative to each other.

17. The trash can assembly of claim 1, wherein the biasing member is configured to bias the clutch mechanism generally along a longitudinal axis of the shaft.

18. The trash can assembly of claim 1, wherein the clutch mechanism is configured to move relative to the end member in response to the lid being moved manually while the clutch mechanism remains engaged with the lid driving mechanism.

19. The trash can assembly of claim 1, wherein the clutch mechanism and the lid driving mechanism are configured to disengage from each other in response to manual operation of the lid in at least some situations.

20. The trash can assembly of claim 1, wherein the clutch mechanism is configured to apply a torque to the lid driving mechanism in a circumferential direction around a pivot axis that is generally parallel to the shaft.

21. A trash can assembly comprising:

a body component;

a lid mounted relative to the body component and configured to move between open and closed positions, the lid having a lid driving mechanism that is attached to a bottom surface of the lid;
