Abstract
A trash can with a power operated lid can include a lifting mechanism with a motor, a lifting member, and a variable gear. In some embodiments, the motor is operably connected with the variable gear such that the motor can drive the variable gear and/or the lifting member. In certain implementations, the variable gear includes one or more teeth with varying tooth radii. In some variants, the variable gear and a clutch member are engageable and are configured to allow manual operation of the lid.
