  • Patent number: 5881896
    Abstract: A refuse container (10) includes an open-top receptacle (12) that is selectively closed by a removable hood (14). The hood (14) carries a roll-back door (22) that is operatively connected to a foot pedal (16) by a pair of lifters (18). The container (10) is designed so that the door (22) rolls back to an open position when the foot pedal (16) is depressed. The connection between the foot pedal (16) and the door (22) allows the hood (14) to be removed from the receptacle (12) without requiring the user to disconnect the linkage. As such, the linkage is automatically disassembled when the hood (14) is removed and automatically reassembled when the hood (14) is placed on the receptacle (12). The connection generally includes an engagement bar (70) that projects from an upper end of each lifter (18). The door (22) has a pair of arms (88) that each have a slot (84) therein. When the hood (14) is placed on the receptacle (12), the slots (86) engage the engagement bars (70).

  • Patent number: 5758888
    Abstract: A container (10) and dolly (14) assembly, comprising a container having a planar rearward side (18) and a lid (12) that is pivotally coupled to one of the container handles (34) and pivots thereabout into a vertical orientation against the container (10). Retention flanges (45, 80) of the container (10) and the lid (12), respectively, overlap to lock the lid in the open position. A dolly (14) is provided having upwardly directed tine members (118, 122) that engage container flanges (58, 60) as the container is lowered upon the dolly to latch the container and dolly together. A pivotal foot pedal (38) is disclosed, operable to laterally move one dolly tine member (122) and thereby facilitate disengagement of both container flanges (58, 60) from the dolly tine members (118, 120).
