摘要： A shelflike supporting structure extensible into a generally horizontal operating position and retractable into a generally vertical position within a vertically oriented storage space within a housing, through a vertically oriented opening in the housing. The supporting structure is rotatable about a fore-andaft axis into its operating position after extension from the housing, and may remain free to rotate about this fore-and-aft axis, or it may be locked against such rotation. The supporting structure includes a supporting member having an element mounted thereon for pivotal movement about a pivot axis which is perpendicular to the fore-and-aft axis and which is generally horizontal when the supporting structure is in its operating position. This element may be a gimbal ring which maintains a glass substantially vertical, despite attitude changes of an airplane, for example, if the supporting structure is free to rotate about the fore-and-aft axis. The element mentioned may also be a stirrup on which a glass may be seated, an ashtray cover, a brace for the supporting structure, and the like. Also disclosed is an insulating collar for supporting a glass in a ring.
