    Abstract: A collapsible bed frame (18) for supporting a mattress, the collapsible frame (18) having a number of frame members (32). A number of pivots (34) connect pairs of the frame members (32) at the midpoints of the frame members (32) to make a number of scissor pairs (35). Pivot assemblies (36) pivotally attach the upper ends of the frame members (32) to upper connector assemblies (40), and pivotally attach lower ends of the frame members (32) to feet (38), thus connecting the scissor pairs (35) to form an extended scissors-frame assembly (33). The upper connector assemblies (40) form a support surface for a mattress.

  • Patent number: 6035468
    Abstract: A folding bed having a three section mainframe, a swinging left frame, a swinging right frame, these swinging frames hingedly attached on each end of a third stationary section at a mid portion of the mainframe. Foldaway legs are each hingedly connected near a longitudinal edge of the folding mainframe. These above features are in combination with a detachable middle support leg attaching to each third stationary section on the two longitudinal sides of the mainframe. A first structure element is attached to the head lateral side forming the head board, this structure element differing in design from a second structure element attached to the foot lateral side forming the foot board. The mattress support element on the mainframe is made up of independent rows of flexible metal structure running from one longitudinal side of the mainframe to its opposite corresponding longitudinal side.

  • Patent number: 5608930
    Abstract: A foldable bed includes a pair of legs arranged between a head member and a foot member. Four pairs of pivot axels are arranged between and coupled to the members and the legs by four pairs of links. Two pairs of frames are pivotally coupled between the legs and the members and each pair include a middle portion pivotally coupled together by a hinge member so as to allow the frames to be folded upward about the hinge member and so as to support the frames in horizontal position by the hinge member. The bed may be folded to a rather compact configuration.

  • Patent number: 5568658
    Abstract: A convertible bed-chair assembly comprises first and second solid assembly members which fit together in two different configurations. Corresponding planar surfaces of the members each include a cavity therein which is formed by an internal wall of the corresponding member and is unbounded at a first sidewall of the member. The assembly members each further include one or more recesses in a side wall thereof opposite the first sidewall. A pair of simple latches connect the members together in first, bed configuration wherein the first sidewalls of the members are in abutment and the cavities cooperate to form a concavity for receiving a futon or mattress. A further pair of simple latches connect the members together in a second, chair configuration wherein the first planar surfaces are in abutment and the first and second cavities form an internal storage space, and the recesses of the members are aligned to form a seat or seats.
