Abstract: A latch is disclosed for positioning and releasably retaining articulated linkages such as the pivotally interconnected head and body section angles of a folding sofa sleeper bed frame. The latch includes a connecting link pivotally connected at one end to the body section having at its opposite end an elongated slot including a latching notch, a latch plate slidably mounted on the connecting link having an elongated slot which overlies a portion of the length the slot in the connecting link, and a pin connected to the head section angle making a lost motion connection within the connecting link and latch plate slots.

Abstract: A sofa or davenport having a foldable bed frame adapted to provide a seat when used as a sofa and a forwardly extending unfolded bed frame when used as a bed. The foldable frame includes pivotally interconnected head, body, intermediate and foot sections and a linkage operable to automatically control extension and contraction of the supporting legs and to control folding and unfolding of the interconnected sections between a fully extended, unfolded position wherein the sections extend over the sofa storage cavity and front rail; and a retracted position wherein the body, intermediate and foot sections are disposed substantially entirely below the plane of the top surface of the front rail of the sofa and the head section is disposed behind the back rest cushion of the sofa.
