DETAILED DESCRIPTION

A convertible couch, single bed, and queen bed (the “article”) is disclosed.FIGS. 1-3are different views of the article10configured as a couch.

The article10has a U-shaped section12, a first end section14A, a second end section14B, and a mattress section18.

The U-shaped section12has a first arm12A, a second arm12B, and a back section12C. The back section12C is between, and joined to, the first arm12A and the second arm12B. The U-shaped section12may 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 section12C is selectively removable from the first arm12A and second arm12B, such as by a hook and loop fastener or other conventional fastener. The first arm12A has a face12D distal to the back section12C, and the face12D has a frontal bottom edge12E. The second arm12B has a face12F distal to the back section12C, and the face12F has a frontal bottom edge12G. In the couch configuration the U-shaped section12rests on the end sections14A,14B, and a portion of the mattress sections18A-18C.

The first end section14A has an upper front edge14C, an internal bottom edge14G, and an internal top edge14E (FIG. 7). The upper front edge14C of the first end section14A is rotatably joined to the frontal bottom edge12E of the first arm12A by a hinge or joint16A. The hinge16A may be thread, fabric, or other means of rotatably joining the upper front edge14C to the frontal bottom edge12E. The internal top edge14E of the first end section14A has a first part30A of a first closure element, such as a zipper, hook and loop fastener or other fastener type (FIG. 7).

The second end section14B has an upper front edge14D, an internal bottom edge14H, and an internal top edge14F (FIG. 6). The upper front edge14D of the second end section14B is rotatably joined to the frontal bottom edge12G of the second arm12B by a hinge or joint16B. The hinge16B may be thread, fabric, or other means of rotatably joining the upper front edge14D to the frontal bottom edge12G. The internal top edge14F of the second end section14B has a first part30C of a second closure element, such as a zipper, hook and loop fastener or other fastener type (FIGS. 6, 7).

The first mattress section18A has a second part30B of the first closure element which mates with the first part30A, and also has a second part30D of the second closure element which mates with the first part30C (FIG. 7). One part of a closure element30A,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 element30C,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. InFIGS. 6 and 7, the slides are shown as being associated with the end sections14A,14B. In another embodiment, the slides may be associated with the mattress section18A.

FIG. 4illustrates the article10configured as a day bed. A rotating or folding action20converts the article10from a couch into a day bed. The U-shaped section12is rotated20, or folded over, along the hinges16A,16B, so that the mattress sections18A-18C are partially enclosed within the U-shaped section12.

FIG. 5illustrates the article10rotated22by180degrees (with respect toFIG. 4) in preparation for conversion into a queen bed. If the back section12C (FIG. 1) is against a wall or a piece of furniture (not shown) then the article10may be moved away from the wall or piece of furniture to provide space for the conversion, or the article10may be rotated as shown. If the article10is positioned so that there is space for the mattress18to be unfolded, such as toward the center of a room, then movement or rotation may be avoided. For convenience of discussion below, the article10is shown as being rotated22(with respect toFIG. 4).

FIGS. 6 and 7illustrate the article10being converted from a day bed into a queen bed by unfolding the mattress18. The closure elements30A-30D are separated so that the mattress section18A may be unfolded from the mattress section18B. The mattress sections18A,18B are then unfolded24along the hinges20A,20B.

FIGS. 7, 8 and 9illustrate the article10configured as a queen bed.

If the article10is configured as a queen bed, then it is converted to a day bed by folding up the mattress sections18A,18B,18C and re-engaging the closure elements-30D. If the article10is configured as a day bed it is converted to a couch by rotating or folding (opposite to the rotation20ofFIG. 3) the U-shaped section12back 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.
