ABSTRACT:
An adjustable and foldable bed frame includes a pair of side rails and a pair of end rails extending transversely between the side rails. Each end rail includes a pair of elongated elements, with each of the elements having one end secured to a corresponding side rail and the other end of each element is in slidable relationship to the other element. The elements are releasably locked together by means of a protrusion on one element which is receivable in an opening in the other element. The opening defines a plurality of teeth, and the element with the protrusion has a spring loaded pawl member which is received in the opening and engages the teeth one at a time and permits the elements to be moved inwardly toward one another, while engagement between the pawl and the teeth prevents the elements from moving outwardly relative to one another.
Brackets are provided for pivotably mounting each of the elements to the respective side rails so that the elements can be rotated between a working position generally perpendicular to the respective side rails and a position generally parallel to and alongside the respective side rails. The bracket has one end secured to an element and an opposite end pivotably mounted to the side rail as with a rivet.
