Interlocking stackable housing structure

摘要

A surgical accessory equipment housing having mounting pads at the lower corners which permit stacking of a plurality of such housings by serving as a non-slip support for the bottom housing and as an interlocked spacer between the stacked housings. Each pad has a right angular foot which engages the upper corner of a subjacent housing with spacer ribs disposed between the housings. The bottom housing rests on a flat surface, supported by the four feet of its mounting pads.
