  • Publication number: 20190276232
    Abstract: Various trash can assembly embodiments are disclosed. The trash can assembly can include a body, a lid, an actuation system, and an active dislodgement or return system. The active dislodgement or return system can be configured to facilitate dislodging the trash can assembly from a surrounding environment, such as a wall. The active dislodgement or return system can include a dynamic member having a frame, a foot movably coupled to the frame, and a spring applying a force on the foot. When an actuation force is removed from the actuation system, the dynamic member can apply a force against the surrounding environment, such as a floor, to move the body relative to the surrounding environment.

  • Publication number: 20190185263
    Abstract: Various trash can assembly embodiments are disclosed. In some embodiments, the trash can assembly includes a body and a lid assembly. The lid assembly can include a lid, and a multicomponent trim ring. The lid assembly can be rotatably connected with the body via a hinge unit. In certain embodiments, a flange of the trim ring is guided into and/or received into the hinge unit. A translating pin of the hinge unit can engage into the flange, thereby providing a rotatable connection between the trim ring and the body. In various embodiments, the translating pin is coupled with a handle to facilitate movement of the pin by a user during engagement of the trim ring and the hinge unit. A positioner can help to position the trash can against or adjacent to a wall or other structure. The movement of both the trim ring and the lid can be dampened.
