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.

First claim

The following is claimed:

1. 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;
a power operated driving mechanism comprising a motor coupled with a shaft;
a clutch mechanism engageable with the lid driving mechanism, the clutch mechanism configured to receive torque from the motor and to transmit the torque to the lid driving mechanism to move the lid between the open and closed positions; and
a biasing member configured to bias the clutch mechanism into engagement with an end member of the power operated driving mechanism;
wherein the lid driving mechanism and the clutch mechanism are configured to engage, and wherein the clutch mechanism is configured to translate along, and rotate about, the shaft in the assembled trash can assembly.

2. The trash can assembly of claim 1 , wherein:
the lid driving mechanism is attached to a bottom surface of the lid and is configured to abut with the clutch mechanism; and
the trash can assembly is configured such that, when the power operated driving mechanism is operated, the clutch mechanism moves the lid between the open and closed positions.

3. The trash can assembly of claim 1 , further comprising a trim member, the trim member and the lid being configured to rotate about the same axis.

4. The trash can assembly of claim 1 , further comprising a trim member rotatably coupled with the body and configured to move between first and second positions, wherein:
in the first position, a front of the trim member is adjacent a front upper edge of the body component; and
in the second position, the front of the trim member is spaced apart from the front upper edge of the body component.

5. The trash can assembly of claim 4 , wherein:
a majority of the periphery of the lid is received in the trim member when the trim member is in the first position and the lid is in the closed position; and
a majority of the periphery of the lid is positioned outside of the trim member when the trim member is in the first position and the lid is in the open position.

6. The trash can assembly of claim 4 , wherein trash can assembly is configured such that, when the trim member is in the first position and an upper portion of a removable liner is positioned over the front upper edge of the body component, the trim member engages the upper portion of the removable liner and the front upper edge of the body component.

7. The trash can assembly of claim 4 , wherein the trim member further comprises a retaining mechanism configured to maintain the trim member in the second position.

8. The trash can assembly of claim 7 , wherein the retaining mechanism comprises a first cam structure and a second cam structure, the first cam structure configured to be received in a recess of the second cam structure when the trim member moves from the first position toward the second position.

9. The trash can assembly of claim 4 , wherein the power operated driving mechanism is activated at least in part in response to a signal from a sensor.

10. The trash can assembly of claim 9 , wherein the trash can assembly is configured such that, when the trim member is in the second position, at least one of the power operated driving mechanism and the sensor is deactivated.

11. The trash can assembly of claim 1 , wherein the clutch mechanism is configured to:
rotatably engage with the lid;
receive torque from the end member of the power operated driving mechanism so as to move the lid between the open and closed positions.

12. The trash can assembly of claim 1 , wherein the end member is rigidly coupled to the shaft such that the end member is inhibited from rotating relative to the shaft.

13. The trash can assembly of claim 12 , wherein trash can assembly is configured such that the biasing member translates the clutch mechanism into engagement with the end member.

14. The trash can assembly of claim 13 , wherein the clutch mechanism and the end member comprise corresponding cam surfaces configured to allow the clutch mechanism to translate and rotate relative to the end member.

15. The trash can assembly of claim 14 , wherein the clutch mechanism comprises a first inclined cam surface and the end member comprises a second inclined cam surface, the first and second inclined cam surfaces configured to allow mating engagement between the clutch mechanism and the end member.

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;
a power operated driving mechanism comprising a motor coupled with a shaft; and
a clutch mechanism engageable with the lid driving mechanism, the clutch mechanism configured to receive torque from the motor via the shaft and to transmit the torque to the lid driving mechanism to move the lid between the open and closed positions, the clutch mechanism being configured to translate along, and rotate about, the shaft in the assembled trash can assembly;
wherein the lid driving mechanism and the clutch mechanism are configured to abut and are further configured to allow a user to manually move the lid between the open and closed positions substantially without applying torque to the motor;
wherein the trash can assembly is configured such that, when the power operated driving mechanism is operated, the clutch mechanism moves the lid between the open and closed positions.

22. The trash can assembly of claim 21 , wherein the lid driving mechanism comprises radially inwardly extending first and second flanges configured to abut with first and second torque transmission members of the clutch mechanism respectively, such that rotation of the clutch mechanism rotates the first and second flanges and the lid moves between the open and closed positions.

23. The trash can assembly of claim 22 , wherein the first and second flanges are positioned on the lid such that circumferential spaces are defined between the first and second flanges, wherein the first and second torque transmission members are configured to be positioned within the circumferential spaces.

24. The trash can assembly of claim 23 , wherein the first and second torque transmission members comprise first and second arms extendin
