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.
Claims20
A bed frame comprising:
- a plurality of frame members, each frame member of said plurality of frame members having a first end, a second end and an intermediate point therebetween;
- a plurality of pivots, each pivot of said plurality of pivots pivotally connecting two frame members of said plurality of frame members at said intermediate point;
- a plurality of first connector assemblies;
- and
- a plurality of second connector assemblies,
- each said frame member pivotally coupled at said first end to a corresponding first connector assembly of said plurality of first connector assemblies and pivotally coupled at said second end to a corresponding second connector assembly of said plurality of second connector assemblies, said bed frame movable between a collapsed position and an extended position in response to inflation of an inflatable mattress coupled to one of said plurality of first connector assemblies and said plurality of second connector assemblies, in the extended position said one of said plurality of first connector assemblies and said second connector assemblies configured substantially planar to support said mattress.
A bed frame for supporting a mattress, said bed frame comprising:
- a plurality of frame members, each frame member of said plurality of frame members having a first end, a second end and an intermediate point therebetween;
- a plurality of pivots, each pivot of said plurality of pivots pivotally connecting two frame members of said plurality of frame members at said intermediate point;
- a plurality of first connector assemblies;
- a plurality of second connector assemblies;
- a plurality of first pivot assemblies, each first pivot assembly of said plurality of first pivot assemblies pivotally attaching said first end to a corresponding first connector assembly of said plurality of first connector assemblies;
- and
- a plurality of second pivot assemblies, each second pivot assembly of said plurality of second pivot assemblies pivotally attaching said second end to a corresponding second connector assembly of said plurality of second connector assemblies,
- said bed frame movable between a collapsed position and an extended position, one of said plurality of first connector assemblies and said plurality of second connector assemblies supporting said mattress in the extended position, in the extended position each of said plurality of first connector assemblies and said second connector assemblies configured substantially planar to support said mattress, said mattress configured to inflate and deflate, and to lie on one of said plurality of first connector assemblies and said plurality of second connector assemblies in the extended position.
A bed frame comprising:
- a plurality of frame members, each frame member of said plurality of frame members having a first end, a second end and an intermediate point therebetween;
- a plurality of pivots, each pivot of said plurality of pivots pivotally connecting two frame members of said plurality of frame members at said intermediate point;
- a plurality of first connector assemblies;
- and
- a plurality of second connector assemblies,
- each said frame member pivotally coupled at said first end to a corresponding first connector assembly of said plurality of first connector assemblies and pivotally coupled at said second end to a corresponding second connector assembly of said plurality of second connector assemblies, said bed frame movable between a collapsed position and an extended position, at least one first connector assembly and at least one second connector assembly positioned within a perimeter of said bed frame in the extended position, in the extended position each of said plurality of said first connector assemblies and said second connector assemblies configured substantially planar to support said mattress, said mattress configured to inflate and deflate, and to lie on one of said plurality of first connector assemblies and said plurality of second connector assemblies in the extended position.
A support frame configured to support a mattress, said support frame comprising:
- a plurality of frame members, each frame member of said plurality of frame members having an upper end and a lower end, said upper end pivotally attached to a corresponding upper connector assembly of a plurality of upper connector assemblies, and said lower end pivotally attached to a foot;
- and
- a plurality of extendable corner uprights, each corner upright of said plurality of corner uprights coupling a corner upper connector assembly and a corresponding foot, and including a first member slidably positioned within a second member, said support frame movable between a collapsed position and an extended position, in the extended position said plurality of upper connector assemblies configured substantially planar to support said mattress, said mattress configured to inflate and deflate, and to lie on said plurality of upper connector assemblies.
A support frame configured to support a mattress comprising a plurality of frame members coupled in a scissor structure and configured to be deployed in response to inflation of said mattress from a collapsed position to an extended position, in the extended position each connector assembly of a plurality of connector assemblies coupled to a corresponding frame member and said plurality of connector assemblies configured substantially planar to support said mattress, and a plurality of extendable corner uprights, each corner upright of said plurality of corner uprights coupling a corner upper connector assembly and a corresponding foot, and including a first member slidably positioned within a second member.
A method for extending a collapsible bed frame, said method comprises:
- providing a collapsible bed frame including a plurality of scissor frame members;
- providing an inflatable mattress coupled to the scissor frame members;
- and
- extending each of a plurality of first connector assemblies and a plurality of second connector assemblies outwardly with respect to a central area of the bed frame in response to inflation of the mattress from a collapsed position to an extended position, in the extended position a plurality of connector assemblies each coupled to a corresponding frame member and configured substantially planar for supporting the mattress.
