A receptacle comprising a body including an opening having a door hingedly mounted therein for movement between a normal and substantially vertical orientation and a substantially horizontal orientation, a drive assembly having a hub for taking up and letting out the cord for moving the door between the substantially vertical orientation and the substantially horizontal orientation, and an actuator device for actuating the drive assembly, the hub being spaced apart from said hinge proximate an optimum position for minimizing the amount of force necessary for the drive assembly to move the door.

[ Having fully described the invention in such clear and concise terms as to enable those skilled in the art to understand and practice the same, the invention claimed is:] [1.] A system for moving a door from a normal substantially vertical orientation to a substantially horizontal orientation, said system comprising:said door having an upper edge mounted to an axis of rotation;a drive means for moving said door between said substantially vertical orientation and said substantially horizontal orientation, said drive means being spaced apart from said axis of rotation proximate an optimum position for minimizing the amount of force necessary to move the door from said substantially vertical orientation to said substantially horizontal orientation;an actuating device for actuating said drive means; anda moment arm of applied force about the axis of rotation, said moment arm being smallest when said door is disposed in said substantially vertical orientation, and continuously increasing as said door moves toward said substantially horizontal orientation.
