US Classification:

5201, 5 531, 52791, 52821, 5308

Abstract:

A folding mattress support system replaces both a conventional box spring and the bed frame with rails. The mattress support system is lighter, quieter and easier to transport, and also provides more storage space beneath the mattress. The mattress support system includes bed frame assemblies, central connecting bars, edge attachments and a bed skirt. Leg brackets fold out from the bed frame assemblies, which themselves unfold in the middle. Central connecting bars connect inner side edges of the bed frame assemblies. Plastic edge attachments are attached at outer corners of the bed frame assemblies and hold a bed skirt taught around the frame assemblies when the frame assemblies are standing on the extended leg brackets. A mattress is then placed on top of the assembled mattress support system. Optionally, metal edge attachments at the head corners of the mattress support system both hold the bed skirt and support a headboard.

International Classification:

A47C 19/12

US Classification:

5202, 5201, 51761

Abstract:

A collapsible bed frame that supports a box spring includes side rails and telescoping cross rails. A first hinge connects upper and lower portions of a first side rail that are each at least 35 inches long. A first portion of a cross rail telescopes inside a second portion of the cross rail, and the first portion is connected to the first hinge. Upper and lower portions of a second side rail are connected by a second hinge that includes a slot. The second portion of the cross rail has a tongue that fits into the slot on the second hinge. The side rails also have support legs with flanges that extend above the side rails when the support legs are extended. The first and second hinges also include flanges that together with the support leg flanges prevent the box spring from sliding towards either side of the bed frame.

International Classification:

A47C 17/00

US Classification:

5722, 5618, 5617, 5737

Abstract:

A self-adjusting mattress includes a support member, top and bottom foam layers, a movement mechanism and balancing bars. The support member includes a frame of longitudinal and cross bars and mesh panels between the bars. The support member has a middle section that is pivotally connected to upper and lower sections. The upper, middle and lower sections are coplanar in the flat configuration of the mattress. The movement mechanism includes multiple electric motors that move the mattress into an inclined configuration by rotating the upper and lower sections relative to the middle section. The bottom foam layer is molded around the support member. The molded foam flows above, below and through the holes in the mesh panels. The top foam layer is then glued or molded to the top of the bottom foam layer. The balancing bars extend less than half way under the upper section of the support member.
