Abstract
An improved adjustable cross frame member for use in a bed frame having side frame members and another such adjustable cross frame member. Each cross frame member comprises a pair of elongate elements including first and second perpendicular legs. One of the first legs has a plurality of longitudinally spaced position defining apertures corresponding to selectable positions of the cross frame member. The other of the first legs has a protrusion engageable with one of the apertures for retaining the elements against longitudinal movement in both directions when like legs of the elements are positioned in surface-to-surface adjacency. A locking means retains the elements against separation and includes a plurality of longitudinally spaced threaded openings in the first leg of the first element, each opening being associated with a corresponding aperture. A releasable locking member comprising a thumb screw is permanently mounted on the first leg of the second element and is engageable with the threads in one of the openings to retain the elements against separation.
