Abstract

Abstract A trash compactor formed of a cabinet having a raised support floor upon which an open top trash bag is rested in upright position beneath a compacting ram, and a movable dolly formed of a roller supported frame arranged beneath the support floor and locked thereto by a releasable locking means. A cabinet door is hingedly connected to the frame and has a bag support means upon which the bag is mounted. The door is arranged to tilt forwardly of the cabinet for raising the bag above the floor, for thereby removing the bag, door and frame as a unit, from the cabinet. The door hinge includes a locking means which releasably locks the door in tilted position and simultaneously causes the frame locking member to unlock. A manual control unlocks the door for swinging upright, thereby permitting the frame locking member to re-engage the cabinet door.
