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. The head section of the bed frame is sequentially movable from a lowered position where it is coplanar with the body section, to a ready or 'latch cocked' position which exposes the latching notch in the connecting link for receiving the head section pin, to a TV position where the head section is held in a raised, angulated position with respect to the body section by the head section pin being captured in the latching notch in the connecting link, to a release position where the head section pin is released from the latching notch and the head section is movable back to its lowered position.
