Abstract
A bedframe having side rails interconnected by end crossbars which are adjustable to provide a plurality of different standard bed widths, each of the crossbars being formed by at least two telescoped sections which are interconnected to provide a unitary crossbar assembly in which the component parts are mechanically retained against disassembly, and wherein the sections are arranged to be latched in selective bed width positions by means of a latch member movably supported on the outermost of the telescoped sections for movement between a raised non-latching position in which a projection on the latch member is freely movable along an adjacent side channel formed in the other of the telescoped members, and a latching position in which the projection is moved into one of a plurality of spaced apart slots in communication with the side channel.
