Abstract: A collapsible sofa bed movable between an expanded configuration and a collapsed configuration includes a frame including a plurality of scissor assemblies. Each scissor assembly includes a first frame member pivotally coupled to a second frame member at a pivot point. Frame members of adjacent scissor assemblies are coupled to one of a first connector assembly and a second connector assembly. At least two backrest support members are coupled to the frame. Each backrest support member is slidably coupled to a corresponding first frame member and has a lower end that is pivotally coupled to a corresponding second frame member. Each backrest support member is pivotally movable with respect to the corresponding second frame member.

Abstract: An adjustable folding bed frame including a plurality of longitudinal beams spaced apart and parallel to each other. Each longitudinal beam is formed by a pair of longitudinal bars that are pivotally connected together. The bed frame also includes a plurality of transverse beams spaced apart and parallel to each other. Each transverse beam is formed by a pair of transverse bars that are pivotally connected together. Each transverse bar has a first sliding member slidingly coupled with a second sliding member for adjusting the bed frame to predetermined widths. The bed frame also includes legs connected to a corresponding lower side of each longitudinal bar free end. The longitudinal and transverse bars are coupled together to form a generally rectangular frame when the bed frame is in an open configuration, and are folded adjacent and parallel to each other when the bed frame is in a folded configuration.

Abstract: A foldable mattress support has an adjustable inner frame with a ratchet support for raising the head of a mattress. Legs are incorporated into the side and end bars of the mattress support. Upper and lower bars of the support are pivotally attached to the vertical plate of a hinge. Bolts oriented along axes of rotation pass through the bars and through the vertical plate. A first upper bar pivots about a first axis; a second upper bar pivots about a second axis; a first lower bar pivots about a third axis; and a second lower bar pivots about a fourth axis. Each of the axes is orthogonal to the vertical plate, and the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis. The distal ends of the upper and lower bars are pivotally attached to end bars.

Abstract: A patient lifting apparatus is provided and which is operative to lift an injured person or patient from a lower area to an elevated position where the patient or injured person can be easily and safely transferred to a stretcher or other support device. The patient lifting apparatus includes a pair of side sections that are interconnectable. Each side section includes a lifting device and a lifting bar which is movable up and down. In a connected mode, the two side sections are connected together and the lifting bars include attachments for attaching to a patient support. Once attached to the patient support, the lifting bars via the lifting device are operative to lift the patient support upwardly generally between the two side sections where the patient can be transferred to a stretcher or other structure.

Abstract: A foldable mattress support is made by covering a metal frame with a fabric covering. The metal frame includes two sections that fold together at two hinges. A first section includes first upper and lower frames, and a second section includes second upper and lower frames. Each of the upper and lower frames is pivotally attached to a hinge. A bolt that is oriented along a first axis passes through the first upper frame and through a plate of the hinge. The first upper frame pivots about a first axis; the second upper frame pivots about a second axis; the first lower frame pivots about a third axis; and the second lower frame pivots about a fourth axis. Each of the axes is orthogonal to the plate, and the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis.

Abstract: A foldable mattress support with legs includes a metal frame with a fabric covering. The metal frame includes first upper and lower frames and second upper and lower frames. Each of the upper and lower frames is pivotally attached to a vertical plate of a hinge. A bolt that is oriented along a first axis passes through the first upper frame and through the vertical plate. A leg attaches through the fabric covering to a base plate of the hinge. The first upper frame pivots about a first axis; the second upper frame pivots about a second axis; the first lower frame pivots about a third axis; and the second lower frame pivots about a fourth axis. Each of the axes is orthogonal to the vertical plate, and the third axis is spaced farther apart from the fourth axis than the first axis is spaced apart from the second axis.

Abstract: A foldable supporting device includes parallel supporting frames and foldable units, each of which interconnects an adjacent pair of the supporting frames and includes a pair of crossing members that cross and that are pivoted to each other, and a joint mechanism having a pair of first joints and a pair of second joints that are connected respectively to the adjacent pair of the supporting frames. Each of the crossing members interconnects a respective one of two diagonally aligned pairs of the first and second joints. At least one of the pair of the first joints and the pair of the second joints interconnect upper and lower parts of the adjacent pair of the supporting frames, respectively.

Abstract: In a folding bed with a central dolly, the dolly comprises two separate parts that can be assembled together: a trestle made of a shaped tubular bar which forms two side shoulders and base sections, and two box members of plastic material that are mounted and snap fastened on the trestle shoulders and that are equipped at their ends with seats for the pivotal connection of side parts of the folding bed.
