Abstract: A combination ottoman, table or desk and a foldable sleeper bed comprises upper and lower wooden frame sections, the lower frame section being configured as an open top box, atop which the upper frame section is located. The two frame sections are interconnected by a pair of opposed four-bar linkages which permit the upper frame section to be moved between a first position in which it rests atop and encloses the lower frame section, and a second raised position in which it is spaced upwardly and rearwardly from the lower frame section. Contained within the enclosure defined by the upper and lower frame sections, there is a foldable sleeper bed having pivotally interconnected head, body, intermediate and foot sections, which sections are extendable forwardly from the lower frame section when the upper frame section is in the second raised position to form a bed and foldable to fit and be contained within the enclosure when the bed is collapsed and stored.

Abstract: A folding sofa bed frame structure has a TV control link and an associated toothed ratchet element connected thereto, by which the rear end section of the structure can be selectively positioned in two differing "TV" positions. A cam portion on the ratchet element automatically effects disengagement from either TV position upon pivoting of the rear end section into a substantially perpendicular relation to the main intermediate section of the structure. The ratchet arrangement is effective to automatically engage into and disengage from either TV position without manual manipulation, other than manual lifting of the rear end section, and is automatically effective to disengage when the bed frame structure is folded into the sofa frame.

Abstract: A sofa bed having a foldable bed frame including a main section, center section and front section which are coplanar with one another when the frame is in the bed configuration. A mattress is supported by the foldable frame and folds with it when the bed is closed or stored in the sofa frame. When the foldable bed frame is partially folded, the front section does not fully compress the mattress between the main and front sections. When the partially folded bed frame is moved to the fully folded position inside the sofa frame, a series of links causes the front section of the bed frame to move to a horizontal position and fully compress the mattress. In this fashion, the stored energy in the mattress is reduced when the frame is partially open so as to reduce the possibility of injury to the operator.

Abstract: A sofa-bed assembly comprising a rear vertical section, a lower horizontal section, a front vertical section, and an upper horizontal section pivoted to one another in succession for folding movement between a collapsed sofa condition and an extended bed contidion. A mattress folded within the assembly presses upwardly against the upper horizontal section, and a locking linkage arrangement resists the tendency of the folded mattress to swing the upper horizontal section upwardly out of a horizontal plane when the assembly is in its collapsed condition. Release of the locking linkage involves initially compressing the mattress further, thereby increasing the force required to open the bed. Additional links respond to unfolding of the rear leg, which supports the unfolded lower horizontal section for relieving some of the pressure of the mattress on the upper horizontal section, thereby reducing the force required to open the locking linkage to permit unfolding of the upper horizontal section.
