ABSTRACT:
An improved adjustable cross frame member for use in a bed frame having side frame members and another such cross frame member. The improved member is comprised of first and second elongate L-shaped elements having mutually perpendicular legs. Both elongate elements are provided with a plurality of longitudinally spaced slots and protruding fingers in one leg thereof, with the spacing between slots and fingers and their sizes being alike for both elongate elements. The fingers of each element are oriented to be inserted into respective slots of the opposite element which are complementary therewith when the elements are initially positioned with like legs in face abutting engagement. The elongate elements are then longitudinally moved relative to each other to position each inserted finger in overlapping engagement with the portion of the opposite element adjacent the slot in which the fingers are initially inserted, and thereby positively hold the elements against separation. In order to lock the elements longitudinally in this position, one of the elements includes position defining apertures associated with each of the slots, and the other element includes a releasable resilient member having a detent which engages a position defining aperture when the fingers are moved in overlapping engagement with the elements.
