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.

Abstract: A folding bed frame includes standardized right and left bed frame assemblies that are connectable by central connecting bars to form an adjustable bedboard frame that fits mattresses of differing widths. The bed frame is easy to transport when disassembled into the separate frame assemblies that are each less than half the width of a conventional frame for a double bed. The smaller and standardized frame assemblies reduce manufacturing cost. Foot brackets are pivotally connected to the bottom of the bedboard frame under each bed frame assembly and support the bedboard frame and mattress. Each central connecting bar has U-shaped slots on its ends that clip over the inner side edges of the right and left bed frame assemblies. Each frame assembly has a hinge at its middle axis at which a lower half folds over onto an upper half to allow the assemblies to fit in a packing box.

Abstract: The present invention is a folding and telescopic structure that consists of two parallelograms (1) (2), which can be flattened in opposite directions, located on the same plane and joined articulately by two springs (17) from its front (3) and back (4) jambs. These jambs (3) (4), which are “U” shaped and hollow, allow the end (5) and intermediate (6) crossbars to lodge inside to totally occupy the space available inside the hollow jambs. The end crossbar (5) has a groove (8) in which to slide a first shaft (9) of the back jamb (4) at the same time that a it can turn counter-clockwise upon a second shaft (10) of the front jamb (3) . The intermediate crossbar (6) 15 moves in a similar way, but the hinge (13) that receives the second shaft (12) is not fixed on the intermediate crossbar (6), but can be slid across it. FIG. 1.

Abstract: X and v-shaped mattress supports comprise a pair of pivotal longitudinal members for replacing conventional wooden slats. Each terminal end of each longitudinal member includes a flange for attachment to the side rails of a conventional bed frame. An extendable leg provides additional support for the center of the slat. The method of use consists of pivoting the longitudinal members of the mattress support to accommodate the particular width of the side rails of the selected bed frame. In one alternate embodiment a pair of v-shaped mattress support slats are connected by a divider for containing a pair of mattresses in side-by-side form.
