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.
Claims13
A support frame comprising:
- a plurality of frame members, each frame member having an upper end and a lower end, said upper ends of said frame members being pivotally attached to upper connector assemblies, and said lower ends being pivotally attached to feet, such that the support frame as a whole expands outwardly from a central area.
An articulated support frame comprising:
- a plurality of frame members, said frame members being joined by pivot assemblies, such that the support frame as a whole expands outwardly from a central area.
A collapsible bed frame for supporting a mattress, comprising:
- a plurality of frame members, each frame member having an upper end and a lower end and a midpoint;
- a plurality of pivots which connect pairs of said frame members at said midpoints of said frame members to make a plurality of scissor pairs;
- a plurality of upper connector assemblies;
- a plurality of feet;
- pivot assemblies which pivotally attach said upper ends of said frame members to said upper connector assemblies, and pivotally attach said lower ends of said frame members to said feet, thus connecting said scissor pairs to form an extended scissors-frame assembly, said upper connector assemblies forming support surfaces for a mattress.
A method of installing a collapsible bed frame, comprising the steps of:
- A) providing a collapsible bed frame having a support frame, said support frame including a plurality of frame members, said frame members being joined by pivot assemblies, such that the support frame as a whole expands outwardly from a central area;
- and
- B) expanding said collapsible bed frame outwardly from said central area.
