Abstract: A moveable storage system having one or more storage units, a plurality of flexible track elements conformable with an irregular supporting surface, and an individual base structure which supports each storage unit for movement along the track elements through roller members associated with particular track elements. One or more of the roller members is a load leveling articulated wheel assembly having a pair of spaced roller wheels operative to pivot about an articulation shaft to conform with flexible track profiles to accommodate supporting surface irregularities under and between various track elements spaced along the length of the storage unit.

Abstract: A CRT mounting structure capable of inserting smoothly and readily a CRT into a predetermined position of a cabinet by fixedly securing to the opening of the CRT, guide ribs each having taper surfaces, along the adjacent two sides of an opening substantially in the form of a rectangular shape and by fixedly securing guide posts for guiding the CRT along the opposite edges to the adjacent two edges.
