DETAILED DESCRIPTION

A convertible couch, single bed, and queen bed (the “article”) is disclosed. FIGS. 1-3 are different views of the article 10 configured as a couch.
The article 10 has a U-shaped section 12, a first end section 14A, a second end section 14B, and a mattress section 18.
The U-shaped section 12 has a first arm 12A, a second arm 12B, and a back section 12C. The back section 12C is between, and joined to, the first arm 12A and the second arm 12B. The U-shaped section 12 may be a manufactured as a single component or may be manufactured as separate components which are joined together at a desired later time, such as installation in a dwelling. In one embodiment, the back section 12C is selectively removable from the first arm 12A and second arm 12B, such as by a hook and loop fastener or other conventional fastener. The first arm 12A has a face 12D distal to the back section 12C, and the face 12D has a frontal bottom edge 12E. The second arm 12B has a face 12F distal to the back section 12C, and the face 12F has a frontal bottom edge 12G. In the couch configuration the U-shaped section 12 rests on the end sections 14A, 14B, and a portion of the mattress sections 18A-18C.
The first end section 14A has an upper front edge 14C, an internal bottom edge 14G, and an internal top edge 14E (FIG. 7). The upper front edge 14C of the first end section 14A is rotatably joined to the frontal bottom edge 12E of the first arm 12A by a hinge or joint 16A. The hinge 16A may be thread, fabric, or other means of rotatably joining the upper front edge 14C to the frontal bottom edge 12E. The internal top edge 14E of the first end section 14A has a first part 30A of a first closure element, such as a zipper, hook and loop fastener or other fastener type (FIG. 7).
The second end section 14B has an upper front edge 14D, an internal bottom edge 14H, and an internal top edge 14F (FIG. 6). The upper front edge 14D of the second end section 14B is rotatably joined to the frontal bottom edge 12G of the second arm 12B by a hinge or joint 16B. The hinge 16B may be thread, fabric, or other means of rotatably joining the upper front edge 14D to the frontal bottom edge 12G. The internal top edge 14F of the second end section 14B has a first part 30C of a second closure element, such as a zipper, hook and loop fastener or other fastener type (FIGS. 6, 7).
The first mattress section 18A has a second part 30B of the first closure element which mates with the first part 30A, and also has a second part 30D of the second closure element which mates with the first part 30C (FIG. 7). One part of a closure element 30A, 30B has one set of elements, such as zipper teeth or the hook portion of a hook and loop fastener, and the other portion of the closure element has a corresponding set of elements, such as zipper teeth or a loop portion of the hook and loop fastener. One part of a closure element 30C, 30D has one set of elements, such as zipper teeth or the hook portion of a hook and loop fastener, and the other portion of the closure element has a corresponding set of elements, such as zipper teeth or a loop portion of the hook and loop fastener. In FIGS. 6 and 7, the slides are shown as being associated with the end sections 14A, 14B. In another embodiment, the slides may be associated with the mattress section 18A.
FIG. 4 illustrates the article 10 configured as a day bed. A rotating or folding action 20 converts the article 10 from a couch into a day bed. The U-shaped section 12 is rotated 20, or folded over, along the hinges 16A, 16B, so that the mattress sections 18A-18C are partially enclosed within the U-shaped section 12.
FIG. 5 illustrates the article 10 rotated 22 by 180 degrees (with respect to FIG. 4) in preparation for conversion into a queen bed. If the back section 12C (FIG. 1) is against a wall or a piece of furniture (not shown) then the article 10 may be moved away from the wall or piece of furniture to provide space for the conversion, or the article 10 may be rotated as shown. If the article 10 is positioned so that there is space for the mattress 18 to be unfolded, such as toward the center of a room, then movement or rotation may be avoided. For convenience of discussion below, the article 10 is shown as being rotated 22 (with respect to FIG. 4).
FIGS. 6 and 7 illustrate the article 10 being converted from a day bed into a queen bed by unfolding the mattress 18. The closure elements 30A-30D are separated so that the mattress section 18A may be unfolded from the mattress section 18B. The mattress sections 18A, 18B are then unfolded 24 along the hinges 20A, 20B.
FIGS. 7, 8 and 9 illustrate the article 10 configured as a queen bed.
If the article 10 is configured as a queen bed, then it is converted to a day bed by folding up the mattress sections 18A, 18B, 18C and re-engaging the closure elements-30D. If the article 10 is configured as a day bed it is converted to a couch by rotating or folding (opposite to the rotation 20 of FIG. 3) the U-shaped section 12 back to an upright position.
Thus, an article of manufacture has been described which may be used as a couch, a day bed, or a queen bed. The article comprises a U-shaped section having a first arm and a second arm. The first arm has a face having a top edge. The second arm has a face having a top edge. A first end section has a front edge, an internal bottom edge, and an internal top edge. The front edge of the first end section is rotatably joined to the top edge of the face of the first arm. The second end section has a front edge and a bottom edge. The front edge of the second end section is rotatably joined to the top edge of the face of the second arm. The internal top edge of the first end section has a first portion of a first closure element and the internal top edge of the second end section has a first portion of a second closure element. A mattress has a first mattress section, a second mattress section, and a third mattress section. The first mattress section is rotatably joined to the second mattress section, and the second mattress section is rotatably joined to the third mattress section. The third mattress section has a first bottom edge and an opposing second bottom edge. The first bottom edge of the third mattress section is joined to the bottom edge of the first end section, and the second bottom edge of the third mattress section is joined to the bottom edge of the second end section. The first mattress section has an internal first edge and an opposing internal section edge. The internal first edge has a second portion of the first closure element, and the internal second edge has a second portion of the second closure element. The first closure element releasably joins the first end section and the first mattress section, and the second closure element releasably joins the second end section and the first mattress section.
