This application claims priority to U.S. provisional patent application Ser. No. 61/161,692, filed Mar. 19, 2009. The entire contents of which are herein incorporated by reference.

FIELD OF THE INVENTION

The present invention relates to a convertible sofa bed that can be placed in a room corner and that can be converted from a sofa into a bed.

BACKGROUND

Homes and apartments with small room sizes often have difficulty with the placement and arrangement of furniture. Frequently, a room may have one long wall and a short wall. The short wall may prevent the use of various pieces of furniture. Space is at a premium in these residences and it is beneficial if the furniture used is multi-functional. Sofas and beds are two of the larger pieces of household furniture and their combination can save considerable floor space. While convertible sofa beds have been known, they have lacked the ability to be used with short walls and have lacked a headboard when setup in the bed configuration.

With reference to FIG. 10, a user may push on frame end 260B causing frame 260 to roll or slide towards table 212. Frame 260 and lower headboard portion 227 move through opening 204 into interior area 202 (FIG. 13). At the same time, upper headboard portion 226 may abut top 214 and side panel 216 causing upper headboard portion 226 to remain in a closed position. Frame 260 and mattress 252 continues to slide into interior area 202 until end upper headboard portion 226 contacts side panel interior surface 217A as shown in FIG. 12. This is the retracted position for sofa bed 250 and approximately ½ of frame 260 and mattress 252 is contained within table 212 and the other ½ is located outside of table 212.

With reference to FIGS. 12 and 13, a user may pull on frame end 260B causing frame 260 to roll or slide outwardly from table 212. Frame 260 and lower headboard portion 227 move through opening 204 out from interior area 202. Frame 260 and mattress 252 continues to slide outwardly until latch tab end 281 engages or contacts the back side 226B of upper headboard portion 226. Further pulling on frame 260 causes latch tab end 281 to cause upper headboard portion 226 to rotate about pivot member 270. Thereby, when frame 260 is moved into the bed configuration of FIG. 11, upper headboard portion 226 and lower headboard portion 227 are coplanar forming a unitary headboard 225.

Headboard 418 (FIG. 14) may also be removed from table 412 (FIG. 14). Headboards 418 and 425 may then be moved into an adjacent side by side configuration allowing the formation of a bed such as similarly illustrated in FIG. 3, when additional frames and mattresses are added.

FIG. 16 shows what table 412 looks like after headboard 425 has been removed from table 412 to form bed 800.

3rd Alternative Embodiment

Referring to FIG. 18 a furniture assembly or sofa bed of the present invention, generally indicated by reference number 820 is shown. In FIG. 18, the mattresses, cushions and backrests have been omitted for clarity. Furniture assembly or sofa bed 820 can include a table 12 and platforms or frames 60, 80 and 110, 140 that extends away from table 12. Sofa bed 820 is similar to sofa bed 10 previously described in FIGS. 1-8, except that backrest 830 have been added so that sofa bed 820 may be used in a room or location where a wall is not available to support a back rest cushion. Two rectangular shaped stake holes 840 are located in framed top surface 150 adjacent to rail 148. Back rest 830 comprises a generally horizontally configured back rail, two spaced apart generally vertically stakes 836 and a back board 834 extending across the stakes and to the back rail. Stakes 836 can be inserted into stake holes 840 in order to mount back rest 830 to one of the platforms or frames, such as platform 140. Back rest 832 may be removed by lifting vertically upward on back rest 832 away from the platform allowing stakes 832 to slide out from stake holes 840. Back rest 830 allow for sofa bed 820 to support cushions where a wall is not available to support back rest cushions in a sofa configuration.

With additional reference to FIG. 19 the use and operation of U clips 850 will now be described. U clips 850 allow for the selective retention of various platforms or frames, 60, 80, 110 or 140 to each other as selected by the user. U clip 850 comprises a center section 852 and ends 854 and 856 that extends perpendicularly away from center section 852. A retention hole 860 can be located in top surface 150 of frames 110 and 140. A spring 858 is mounted in one of retention holes 860 and coupled to end 856. Spring 858 biases U clip 850 toward top surface 150. U clips 850 can span between frames 110 and 140 with one end 154 extending into retention hole 860 and the other end 856 retained in retention hole 860. In this manner, U shaped clips 850 are able to retain or hold frames 110 and 140 together. When not in use, U shape clips 850 may be stored by rotating the clip 850, such that end 854 is inserted into storage hole 862. Center section 854 may be pressed downwardly such that the center section is adjacent to top surface 150. The present invention allows the use of a convertible sofa bed in rooms that have short walls or walls that include obstacles such as windows or doors. The sofa bed of the present invention provides a headboard that moves with the bed when conversion from a sofa to a bed occurs. The sofa bed of the present invention allows for the partial storage of a mattress within a table.

Although the description above contains many specifications, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the embodiments of this invention. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents rather than by the examples given.
