BACKGROUND

1. Field of the invention

The present invention relates to furniture that can be converted from a first to a second position. More particularly, the present invention relates to furniture that is a chair when in the first position and a bed when in the second position. Additionally, the present invention relates to furniture that is a sofa when in the first position and a bed when in the second position.

2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98.

Furniture is common in both residential and commercial buildings. Common pieces of furniture include chairs, sofas and beds. Furniture is selected according to the function of the room and according to the style of the room. For example, if the room is to be used for discussions and gatherings, then chairs and sofas may be selected as the furniture items for the room. If the room is to be used for sleeping, then beds are usually selected as the furniture items in the room. Sometimes rooms can be used for both socializing and sleeping. Thus, there is a need to have both a chair and a bed, or a sofa and a bed, in the same room.

One problem associated with furniture items in rooms is that rooms arc not large enough to accommodate both a chair and a bed or both a sofa and a bed. Thus, there is a need for a single piece of furniture that functions as both a chair and a bed or both a sofa and a bed.

Various patents have issued relating to convertible furniture. For example, U.S. Pat. No. 5,647,632, issued on Jul. 15, 1997 to Fireman, discloses a convertible chair that has a base platform, a ground support coupled to the platform, and a seat assembly pivotally connected to the base platform.

A second seat portion 26 is positioned below the first seat portion 12. The second seat portion 26 has a first plurality of legs 28 extending from a bottom surface 44 thereof adjacent a side 34 thereof. The second seat portion 26 also has a second plurality of legs 36 extending from the bottom surface 44 thereof adjacent an opposite side 42 thereof. A first back portion 56 is positioned adjacent the end 16 of the first seat portion 12. The first back portion 56 is received in the channel 14 of the first seat portion 12 when in the first position. A second back portion 92 has a front surface 94 that is positioned a back surface 62 of the first back portion 56 when in the first position. The first back portion 56 has a plurality of keyholes formed in the back surface 62 thereof. The second back portion 92 has a plurality of mushrooms extending from the front surface 94 thereof. The plurality of mushrooms are removably replaced in the plurality of keyholes when the first and second back portions 56 and 92 are in the first position. The mushrooms and keyholes are described in detail in FIGS. 5-9.

The second seat portion has a first pair of projections 46 adjacent an end 48 of the seat portion 26. The second seat portion 26 has a second pair of projections 50 adjacent an opposite end 52 of the second seat portion 26. The first back portion 56 has a pair of holes 64 formed in a top 66 thereof. The pair of holes 64 of the first back portion 56 receive the first pair of projections 46 when in the second position. The second back portion 92 has a pair of holes 106 formed in the top 108 thereof. The pair of holes 106 of the second back portion 92 receives the second pair of projections 50 when in the second position.

The first back portion 56 has a first stopper 72 extending from a side 88 thereof. A second stopper extends from an opposite side of the first back portion 56. The first stopper 72 and the second stopper are positioned adjacent a top surface 54 of the second seat portion 26.

The first seat portion 12 has a first indentation 18 formed in a bottom surface 22 thereof adjacent an end 16 thereof. The first seat portion 12 has a second indentation 20 formed in the bottom surface 22 adjacent an opposite end 24 thereof. The first back portion 56 has an indentation 68 formed in the back surface 62 thereof adjacent a top 66 thereof. The second back portion 92 has an indentation 93 formed in a back surface 95 thereof adjacent a top 108 thereof. The first indentation 18 of the first seat portion 12 is adjacent the indentation 68 of the first back portion 56 when in the second position. The second indentation 20 of the first seat portion 12 is adjacent the indentation 93 of the second back portion 92 when in the second position.

The first plurality of legs 28 have a leg 30 that is adjacent the end 48 of the second seat portion 26. The leg 30 of the first plurality of legs 28 has stopper on a side thereof. The second plurality of legs 36 has a leg adjacent the end 48 of the second seat portion 26. The leg of the second plurality of legs 36 has a stopper on the side thereof. The stoppers of the legs are described in more detail in FIGS. 2 and 4.

A pair of arms 100 extend outwardly from the front surface 58 of the first back portion 56. A leg 112 extends outwardly from the front surface 58 of the first back portion 56 adjacent a bottom 86 thereof. Another leg 114 extends outwardly from the front surface 94 of the second back portion 92 adjacent the bottom 76 thereof. The leg 112 of the first back portion 56 is above the other leg 114 of the second back portion 92 when in the first position.

Referring to FIG. 2, there is shown another perspective view of a preferred embodiment of the furniture assembly 10 of the present invention in the first position. Stopper 40 can be seen as attached to leg 38 of the second plurality of legs 36. The second plurality of legs 36 is attached to the opposite side 42 of the second seat portion 26. The stopper of the first plurality of legs and the stopper 40 of the second plurality of legs 36 are adjacent an overhang 70 of the first back portion 56 when in the first position. The stopper 40 resists a forward force of the overhang 70 so that the first back portion 56 does not rotate from its substantially vertical orientation in the first position. The stopper 72 of the first back portion 56 rests on the top surface 54 of the second seat portion 26. The stopper 72 holds the first back portion 56 in place so that the first back portion 56 docs not move up and down while in the first position. Thus, the stoppers of the second seat portion 26 and the stoppers of the first back portion 56 hold the first back portion 56 relative to the second seat portion 26 so as to maintain furniture assembly 10 in the first position.

Referring to FIG. 3, there is shown a close-up perspective view of the circled portion A shown in FIG. 1. The relationship between the first stopper 72 on the side 88 of the first back portion 56 and the projection 46 on the top surface 54 of the second seat portion 26 can be seen. When in the first position, both the stopper 72 and the projection 46 reside within the indentation 18 that is formed in the bottom surface 22 of the first seat portion 12. The stopper 72 is cylindrical in shape. The projection 46 is also cylindrical in shape. The longitudinal axis of the stopper 72 is perpendicular to the longitudinal axis of the projection 46. The first back portion 56 has a concave portion 87 that tapers inwardly of the side 88 of the first back portion 56. The concave portion 87 allows the end 16 of the first seat portion 12 to extend past the first back portion 56 and reside in the divot 109 that is formed in the front surface 94 of the second back portion 92. The unique carving of the concave portion 87 and the divot 109 allow the first and second back portions 56 and 92 to be received by the channel 14 of the first seat portion 12. The stopper 72 is between the top surface 54 of the second seat portion 26 in the first indentation 18 of the first seal portion 12. The indentation 18 and the top surface 54 arc adjacent to the stopper 72 so as to prevent the stopper from moving upward or downward. The projection 46 is adjacent the stopper 72 so as to prevent the stopper 72 from sliding out of the indentation 18 when the furniture assembly 10 is in the first position.

Referring to FIG. 4, there is shown a close-up perspective view of the circled portion B in FIG. 2. The relationship of the stopper 40 of leg 38 of the second plurality of legs 36 with the overhang 70 of the first back portion 56 can be seen. The overhang 70 extends past the leg 112 of the first back portion 56. The stopper 40 is cylindrical in shape. The stopper 40 extends inwardly from the side of the leg 38. A notched part 116 is attached to the overhang 70. The notched part 116 receives the stopper 40. Particularly, the notched part 116 is formed so as to have an arcuate receiving area that suitably receives the cylindrically-shaped stopper 40. The notched part 116 can be made of any material suitable for receiving the stopper, including aluminum. Once received in the notched part 116, the stopper 40 prevents the overhang 70, and thus the first back portion 56 from moving backwards and forwards when the furniture assembly 10 is in the first position. The leg 112 of the first back portion 56 can be seen as above the leg 114 of the second back portion 92 as located adjacent the bottom 76 of the second back portion 92.

Referring to FIG. 5, there is shown a side elevational view of the furniture assembly 10 of the present invention in the second position. Leg 114 extends downwardly from the second back portion 92. Leg 112 extends downwardly from the first back portion 56. Arm 110 extends downwardly from the first back portion 56. The first plurality of legs 28 extends downwardly from the second seat portion 26. The mushrooms 96 of the second back portion 92 can be seen. As will be described in more detail in FIGS. 7-9, each mushroom 96 has a shaft 100 and a cylindrical member 104. Each mushroom 96 extends outwardly from the front surface 94 of the second back portion 92. The divot 109 of the second back portion 92 can be seen. When in the first position, the divot 109 receives the end 16 of the first seat portion 12. In the second position, as shown in FIG. 5, the divot 109 receives nothing. The divot 109 is adjacent one of the mushrooms 96. The divot 109 is between two of the mushrooms 96. The indentation 68 and the top 66 of the first back portion 56 is received by the indentation 18 of the first seat portion 12. The hole 64 that if formed in the top 66 of the first back portion 56 receives the projection 46 of the second seat portion 26. The end 16 of the first seat portion 12 exerts a downward force on the top 66 of the first back portion 56 so as to keep the projection 46 within the hole 64. The indentation 93 in the top 108 of the second back portion 92 is received by the indentation 20 on the opposite end 24 of the first seat portion 12. The hole 106 formed in the top 108 of the second back portion 92 receives the projection 50 that extends upwardly from the top surface 54 of the second seat portion 26 adjacent an opposite end 52 of the second seat portion 26. The opposite end 24 of the first seat portion 12 exerts a downward force on the top 108 of the second back portion 92 so as to keep the projection 50 within the hole 106. The leg 114 of the second back portion 92, the leg 112 of the first back portion 56, the arm 110 of the first back portion 56, and the plurality of legs 28 of the second seat portion 26 extend downwardly so that the furniture assembly 10 is horizontally level when in the second position. The back surface 95 of the second back portion 92, the back surface 62 of the first back portion 56 and the top surface 15 of the first seat portion 12 are planar with one another when in the second position. The notched part 116 can be seen adjacent leg 112 and the overhang 70.

Referring to FIG. 6, there is shown a perspective view of the furniture assembly 10 of the present invention in the second position. The keyhole 60 can be seen as placed on the back surface 62 of the first back portion 56. As can be seen, there is a concave portion 87 on side 88 and on opposite side 90 of the first back portion 56. The first stopper 72 can be seen as extending outwardly from the concave portion 87 on side 88. The second stopper 74 of the first back portion 56 can be seen as extending outwardly from the concave portion 87 on opposite side 90.

The first and second seat portions 12 and 26 and the first and second back portions 56 and 92 can be suitable for telescoping in the lateral direction. The lateral direction is indicated by the arrows in FIG. 6. Telescoping in a lateral direction allows the furniture assembly 10 to increase the width of the first and second seat portions 12 and 26 and the first and second back portions 56 and 92.

Referring to FIG. 7, there is shown an isolated perspective view of one of the mushrooms 96 of the present invention. The mushrooms 96 are placed on the front surface 94 of the second back portion 92. Each mushroom 96 has a base member 98 positioned adjacent the front surface 94 of the second back portion 92. A shaft 100 extends outwardly from the base member 98. A cylindrical member 104 is positioned adjacent an end 102 of the shaft 100 opposite the base member 98. The cylindrical member 104 has a diameter greater that a diameter of the shaft 100. The base member 98, shaft 100, and cylindrical member 104 can be integrally formed. A notch can be placed in the front surface 94 of the second back portion 92 so as to place the base member 98 in the front surface 94. The base member 98 can be attached to the second back portion 92 by using screws inserted through screw holes 97 that are formed in the base member 98. Alternatively, the base member 98 can be integrally formed with the front surface 94 of the second back portion 92, and the shaft 102 and cylindrical member 104 can be attached to the base member 98 by a method known to someone of ordinary skill in the art, such as by gluing or screwing.

Referring to FIG. 8, there is shown an isolated perspective view of one of the keyholes 60 that is used on the back surface 62 of the first back portion 56. Each of the keyholes 60 has a base structure 78 positioned adjacent the back surface 62 of the first back portion 56. A hole 80 is formed in the base structure 78. The hole 80 has a first portion 82 and a second portion 84. The second portion 84 has a diameter substantially similar to a diameter of the shaft 100 of the mushrooms 96. The first portion 82 has a diameter substantially similar to the diameter of the cylindrical member 104 of the mushroom 96. As can be seen in FIG. 8, the first portion 82 is positioned above the second portion 84. The base structure 78 and hole 80 can be formed of a continuous piece of material. Alternatively, the hole 80 and base structure 78 can be formed in the back surface 62 of the first back portion 56 by tool common in the art. The keyhole 60 can be independently of the first back portion 56 and can be attached to the back surface 62 of the first back portion 56 by screws that are inserted through the screw holes 83.

Referring to FIG. 9, there is shown an isolated perspective view of the mushroom 96 placed in the keyhole 60. The length of the shaft 102 of the mushroom 96 is equal to a thickness of the base structure 78 of the keyhole 60 so that the cylindrical member 104 of the mushroom 96 can be inserted into the first portion 82 of the hole 80 and extend out of the base structure 78 so that the shaft 100 can then be moved into the second portion 84 of the hole 80. Once the shaft 100 resides within the second portion 84 of the hole 80, the base member 98 and cylindrical member 104 keep the shaft 100 from moving forwards and backwards while the mushroom 96 is engaged with the keyhole 60. To remove the mushroom 96, the mushroom 96 is raised upwardly relative to the keyhole 60 and the cylindrical member 104 is past through the first portion 82 of the hole 80 so as to remove the mushroom 96 from the keyhole 60.

The mushroom 96 and keyhole 60 relationship allows the front surface 94 of the second back portion 92 to positioned adjacent the back surface 62 of the first back portion 56 while the furniture assembly 10 is in the first position. The mushrooms 96 and keyholes 60 are not utilized while the furniture assembly 10 is in the second position.

Referring to FIG. 10, there is shown an isolated perspective view of the notched part 116 of the present invention. As described above in FIGS. 4 and 5, the notched part 116 has a receiving area 118 that receives the stoppers 32 and 40 of the second seat portion 26. Referring back to FIG. 10, the notched part 116 has a top wall 124 and a back wall 122.

Holes 120 are formed in the receiving area 118 of the notched part 116 so as to mount the notched part 116 to the leg 112 and overhang 70 with screws or any other appropriate means. The receiving area 118 is arcuate in shape so as to receive cylindrically-shaped stoppers 32 and 40. One notched part 116 is mounted on each side of the first back portion 56 so that a notched part 116 will receive each of the stoppers 32 and 40 of the second seat portion 26.

Referring to FIG. 11, there is shown a perspective view of another embodiment of the furniture assembly 210 in the present invention. The first seat portion 212, the second seat portion 226, first back portion 256, and the second back portion 292 have a width that is greater of similar portions in the preferred embodiment of the furniture assembly 10. The furniture assembly 210 functions as a sofa in the first position and a bed in the second position rather than a chair in the first position and a bed in the second position. The width of the first seat portion 212 and the second seat portion 226 and the first back portion 256 and the second back portion 292 can be made wider in the furniture assembly 210 by making solid pieces of the portions 212,226,256 and 292 wider than the corresponding portions 12, 26, 56 and 92 of the preferred embodiment 10. The portions 212, 226,256, and 292 can also be made wider by telescoping the portions 12, 26, 56, and 92 of the preferred embodiment 10 laterally outwardly.

The structural members of the alternative embodiment of the furniture assembly 210 have similar relations to the structural members of the preferred embodiment of the furniture assembly 10. For example, the front surface 294 of the second back portion 292 is adjacent the back surface 252 of the first back portion 256. The leg 312 of the first back portion 256 is positioned above the leg 314 of the second back portion 292 when in the first position. The first back portion 256 has a first stopper 252 that is adjacent a projection 246 on the top surface 254 of the second seat portion 226.

The first seat portion 212 has a channel 214 formed in an end 216 thereof. A second seat portion 226 is positioned below the first seat portion 212. The first plurality of legs 228 extends from a bottom surface 244 of the second seat portion 226 adjacent the side 234 thereof. A second plurality of legs 336 extends from the bottom surface 244 of the second seat portion 226 adjacent an opposite side 242 thereof. The first back portion 256 is positioned adjacent the end 216 of the first seat portion 212. The first back portion 256 is received in the channel 214 of the first seat portion 212 when in the first position. A first pair of projections 246 extend upwardly from a top surface 254 of the second seat portion 226. The first pair of projections 246 are adjacent end 248. A second pair of projections 250 extend upwardly from the top surface 254. The second pair of projections 250 are adjacent the opposite end 252 of the second seat portion 226. A first stopper 272 is affixed to a side 288 of the first back portion 256. The stopper 272 is positioned between the first seat portion 212 and the second seat portion 226 so as to prevent an upward and downward movement of the first back portion 256. A pair of holes are formed in the front surface 258 of the first back portion 256 adjacent a top 266 thereof. A pair of arms 310 extend outwardly from the front surface 258 of the first back portion 256. Leg 312 extends outwardly from the first back portion 256. Leg 314 extends outwardly from the bottom of the second back portion 292. Leg 312 is positioned above the leg 314 when in the first position. The first plurality of legs 228 of the second seat portion 226 extend downwardly from a bottom surface 244 of the second seat portion 226 adjacent a side 234 thereof. A second plurality of legs 236 extend downwardly from the bottom surface 244 of the second seat portion 226 adjacent an opposite side 242 thereof.

The foregoing disclosure and description of the invention is illustrative and explanatory thereof. Various changes in the details of the illustrated construction can be made within the scope of the present claims without departing from the true spirit of the invention. The present invention should only be limited by the following claims and their legal equivalents.
