Abstract
Abstract Collapsible support stand for an electronic musical keyboard and the like consisting of a floor-engageable base member, a vertical post upstanding from the base member, a table top for supporting an electronic keyboard, and a rotary bearing member between the post and table top enabling the latter to be swiveled in use. Tapered joints between the bearing and base members, and the post, enable the stand to be assembled by press bits, and disassembled, without tools. The disasembled post and base member are held by straps and hooks against the underside of the table top in a compact carrying mode for convenient transport between points of use.
