BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates generally to furniture which can be transformed from a bed to a sofa to a desk.
2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
Transformable beds which can be elevated to make room for additional living space are well known in the art. These beds, often called Murphy Beds, generally consist of a base member with a bedframe pivotally mounted thereto. The bedframe can be pivoted between a lowered position wherein the bed is horizontal and parallel to the floor, and an elevated position wherein the bedframe is vertically oriented and perpendicular to the floor. In its lowered position, a user can use the bed much like any standard bed. When the bed is not in use, it can be placed into its elevated position which allows the bed to occupy less space.
Other design approaches have been taken to create a bed which transforms into a sofa. For example, the mattress frame can be made to fold such that the bed can transform into a sofa. Bed/sofa transformable furniture has been available for some time as a result of various designs. However, to date there have been few attempts at a transformable bed which can transform between three separate orientations to form a single piece of furniture which can fulfill more than two separate roles.
BRIEF SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a piece of furniture which can transform between a bed, a sofa seat and a work desk. The furniture includes a housing having right and left frame members coupled together by at least one transverse member. A bed frame is positioned between and pivotally coupled to the frame members and the bed frame is pivotally movable between a horizontal orientation and a vertical orientation. Right and left elongated arms are pivotally coupled to the right and right and left frame members and a desk member is coupled to the arms. The desk member extends between the frame members, the desk member having opposite first and second ends pivotally coupled to the left and right elongated arms, respectively. A seat member is pivotally connected to the desk member and positioned between the desk member and the bed frame with the seat member extending between the frame members. The seat member has opposite first and second ends pivotally connected to the first and second ends of the desk member, respectively. The desk member and the seat member are movable between a seat orientation and a desk orientation when the bed frame is in its vertical orientation, the seat member being horizontally oriented with the desk member positioned below the seat member when in the seat orientation, the desk member being elevated with the seat member being vertically oriented when in the desk orientation.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the preferred typical embodiment of the principles of the present invention.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIG. 1, a convertible bed (furniture) made in accordance with the present invention is shown generally as item 10 and consists of a pair of left and right frame members 12 and 14. It will be appreciated that transformable bed 10 has bilateral symmetry so that the left and right sides are identical with identical components. For the purposes of this disclosure, only one side, the left side, will be discussed in detail, but it is to be understood that every component and feature found on the left side has it's mirror image on the right side. Frame member 12 is preferably L-shaped having upper portion 16 and lower portion 18 (a right L-shaped member 12 having an upper right portion 16 and a lower right portion 18, the lower right portion being set at a right angle to the upper right portion and having a bottom right edge 13 and a top right edge 15; a left L-shaped member 14 having an upper left portion 17 and a lower left portion 19, the lower left portion being set at a right angle to the upper left portion and having a bottom left edge 21 and a top left edge 23). Transverse members 20 are mounted to frame members 12 and 14 so as to keep the two frame members rigidly parallel to each other. Bedframe 22 is positioned between frame members 12 and 14. The bed frame has opposite ends 24 and 26 which are pivotally coupled to frame members 12 and 14, respectively.
Bed frame 22 is dimensioned and configured to receive bed mattress 28. Desk member 30 is movably mounted to frame members 12 and 14 below bed frame 22. Seat member 32 is pivotally mounted to desk member 30 and is positioned between the desk member and bed frame 22. Bed frame 22 can pivot between a horizontal orientation as shown in FIG. 1 and a vertical orientation as shown in FIG. 2. When the bed frame is in its horizontal orientation, bed 10 can be used as a standard bed with the user being able to recline onto the horizontally positioned mattress. Additional support legs may be provided at end 25 of the bed frame to provide additional support to the bed frame when someone rests on the mattress.
Referring now to FIG. 2, when bed frame 22 is in its vertical orientation, the bed frame will be nestled within upper portions 16 of frame members 12 and 14 and seat member 32 will be exposed. Seat member 32 can take the form of a frame which is configured to receive seat cushion 34. In the orientation shown in FIG. 2, seat member 32 can act as a seat allowing users to use convertible furniture 10 as a sofa. Seat member 32 will have a flat surface (flat seat surface 32A having flat seat surface 32A, first seat edge 32B, second seat edge 32C, top seat side 32D, and bottom seat side 32E) upon which the user can sit on, which in the example illustrated in FIG. 2, is covered by seat cushion 34. Seat member 32 is positioned adjacent top edge 36 of bottom portion 18 of frame members 12 and 14 so that the seat member is nested within and between the frame members. Bed frame 22 acts as a back rest permitting the furniture to appear and act very much like a sofa. Desk member 30 is kept in its lower position adjacent lower edge 38 of frame members 12 and 14.
Referring now to FIG. 3, desk member 30 can be placed in a raised position as shown in FIG. 3. In order to position desk member 30 into its raised position, seat member 32 must be pivoted into a vertical position (as seen in FIG. 3) such that the seat member is parallel to bed frame 26 and perpendicular to desk member 30. Seat member has opposite ends 40 and 42 which are pivotally mounted to opposite ends 44 and 46, respectively, of desk member 30, so pivoting the seat member into its vertical orientation is relatively easy to do. When desk member 30 is in its elevated position, flat surface 48 is held horizontally so that the desk member can act as a desk.
Referring now to FIG. 4, bed frame 22 is pivotally mounted to frame members at pivot point 27 (upper right pivot point 27, upper left pivot point 29). Since only the left side of bed 10 is shown in FIG. 4, we can see that end 24 of bed frame 22 is pivotally connected at point 27 to frame member 12. Support leg 19 may be pivotally connected to bed frame 22 at side 24 to act as a support member to help support the end of bed frame 22 when the bed is in it's bed orientation as shown in FIG. 4. An identical arrangement is found on the right side of bed 10 including the pivot point and the support leg. Desk member 30 is pivotally connected to the frame members by support arms 50 (a right elongated arm 50A pivotally connected to the lower right portion at a lower right pivot point 52 and the first desk end, the lower right pivot point being on a lower right section of the lower right portion orthogonal to the upper right portion; a left elongated arm 50B pivotally connected to the lower left portion at a lower left pivot point 52A and the second desk end, the lower left pivot point being on a lower left section of the lower left portion orthogonal to said upper left portion). Arm 50 is pivotally attached to frame member 12 at point 52 and it is pivotally attached to end 44 of desk member 30 at point 54 (first desk pivot point 54, second desk pivot point 54A). Seat member 32 is pivotally mounted to desk member 30 by pivotal attachment joint 58 such that the seat member is positioned between bed frame 22 and desk member 30. End 40 of seat member 32 has projecting arm 60 with peripheral end 62 (a first projecting arm 60 extending perpendicularly at the first seat end from said bottom seat side toward the elongated desk member and being comprised of a first peripheral end 62; a second projecting arm 60A extending perpendicularly at the second seat end from the bottom seat side toward the elongated desk member and being comprised of a second peripheral end 62A). Peripheral end 62 is pivotally coupled to pivotal attachment joint 58. Projecting arm 60 is dimensioned such that rear end 64 of seat member 32 can be pivoted behind rear end 66 of desk member 30 as shown in FIG. 6.
Referring now to FIG. 5, bed frame 22 can be placed into a vertical orientation as shown wherein the bed frame is preferably nestled between upper portions 16 of the frame members 12. Support leg 19 is folded so that it is parallel with bed frame 22 and tucks in between upper portions 16. Pivot point 27 is positioned such that rear portion 61 of bed frame 22 does not contact rear portion 64 of seat member 32 when the bed frame is in its vertical orientation. In this orientation, seat member 32 is exposed and the user may sit on seat cushion 34 and use transformable bed 10 as a sofa. The weight of seat member 32 and the user sitting on the seat cushion is carried by arm 60 down to desk member 30 which is recumbent on the floor since the desk member is in its lowered orientation.
Referring now to FIG. 6, desk member 30 can be placed into its raised orientation by physically raising the desk member by pivoting arm 50 about pivot point 52. Seat member 32 can be pivoted into a vertical orientation as desk member 30 is raised, with the intent of placing seat member 32 into its vertical orientation where it is parallel to bed frame 22 and perpendicular to the desk member. In this orientation, transformable furniture 10 can be used as a desk. Arm 50 is dimensioned such that here is sufficient room under desk member 30 to accommodate a user's legs permitting the user to use the desk member as a desk. Suspension element 56 (a first dampener 56 pivotally connected to the right elongated arm and the lower right section of the lower right portion; a second dampener 56A pivotally connected to the left elongated arm and the lower left section of the lower left portion) preferably comprises a gas spring which is configured to keep desk member 30 in its raised position.
The present invention has many advantages over the prior art. In particular, the invention permits the same piece of furniture to fulfill three separate functions. Also, by effectively including three separate types of furniture into a single item, considerable space can be saved. The net effect is that this single piece of furniture can be used in spaces where space is at a premium such as a small bedroom or a small apartment.
A specific embodiment of the present invention has been disclosed; however, several variations of the disclosed embodiment could be envisioned as within the scope of this invention.
It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
