ABSTRACT:
Disclosed here is a lid moving mechanism for use with a storage bin. A hinge arm is pivoted at one end to a fixed point on the bin top, and a free end is attached, by a boom, to the lid. A jack device rotates the hinge arm and lid between opened and closed positions. The jack takes the form of a tube, within which is fixed an open-center helical spindle. A turning tube is inserted into this spindle, and a pin engages the spindle windings. When the turning tube is rotated, it is drawn into or forced out of the helical spindle and jack tube, and the hinge arm is correspondingly moved. An extension is attached to the turning tube so that the jack can be operated, and the lid moved, from a remote location.
