Abstract
A galley cart storage system is provided for use with rectangular galley carts ( ), ( ′) each being supported by a number of wheels. The storage system includes a rectangular upright enclosure ( ) and a lift assembly ( ) located within the enclosure ( ) to move one or more galley carts vertically, in a stacked configuration. The enclosure ( ) includes upright corner posts ( ) that aid vertical movement of a galley cart. The lift assembly ( ) includes a motor ( ), a drive screw ( ), and a lifting bracket ( ). The drive screw ( ) is located along one side of the enclosure and is oriented vertically. The drive screw ( ) connects to the motor ( ) such that rotary motion of the motor ( ) causes like rotation of the drive screw ( ). The lifting bracket ( ) is also located adjacent to the drive screw ( ) and is threaded thereon. The lifting bracket ( ) includes a cart interface member adapted to engage the lower end of a galley cart. Activation of the motor ( ) causes rotation of the drive screw ( ) and corresponding movement of the lifting bracket ( ) along the drive screw ( ), thereby causing the galley cart to move vertically within the enclosure ( ), guided along the corner posts ( ).
