Abstract: A support deck for a sofa bed having a plurality of support members is interconnected at joints such that when a force is applied to one side of the deck the deck will yield but when a force is applied to the opposite side, the deck will be relatively resilient. The support members consist of molded plastic links which are serially and pivotally interconnected to form the deck from a number of generally parallel longitudinal columns of links. Each link includes a planar upper surface for supporting the mattress and a reinforcing rib on the lower surface for added strength. Pivot pins are used to interconnect the links and a stop is provided on each end of the link to restrict the upward flexing or movement of the joined links. The links are economically and easily manufactured thereby providing a commercially competitive sofa bed without the detrimental aspects associated with prior sofa bed structures.
Abstract: A structure for housing a bed, for protection of a sleeper against serious injury or death from damage or collapse of the surrounding residence in an earthquake. The bed protection structure has two kinds of for this purpose: various structural integrity preservation, including means to both enhance the structural strength of the bed protection structure and to also allow the bed protection structure to respond to severe mechanical shocks resulting from impact of parts of the residence structure, while maintaining structural integrity of the bed protection structure; and anti-ballistic penetration, to resist ballistic penetration of residence structure debris fragments into the interior of the bed. The structural integrity preservation include an overall geometry of the form of a modified tetragonal anti-prism or MTAP; triangular spacing of structural members in the MTAP geometry; axially reinforced structural members; and vertical support members containing shock absorbing.

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 an articulated folding structure comprises a fixed carrying framework (2) to which a main movable frame (3) is engaged through a pantograph linkage (4), which main frame is movable in a vertical direction.
