Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to folding beds. More particularly, the invention relates to a folding bed with an attached folding bench.




2. Description of the Prior Art




Wall beds and similar folding beds, often referred to as Murphy beds, have been in use for many years. Folding beds are moveable between a substantially vertical storage position to a substantially horizontal position, and visa versa. When in the lowered position, a folding bed may appear to be similar to a normal bed, sometimes with a headboard such as the retractable headboard disclosed in U.S. Pat. No. 5,446,932 to Bue, and assigned to SICO, Inc. When in the raised position, the folding bed is typically confined folded into a wall or storage cabinet in the wall, where it is concealed. These beds provided greater utility of the space, saving space over conventional beds and allowing multiple wide ranging uses of the room with quick and easy conversion between a sleeping room and another use. This cabinet may include shelves or a desk such as the folding beds disclosed in U.S. Pat. Nos. 6,212,710B1 and 4,793,011.




A folding bed cabinet may include a built-in seat or bench that is usable only when the bed is in the upright position. U.S. Pat. No. 5,652,978 discloses such a folding bed with a seating bench that automatically extends upward into a seating position as the bed folds into an upright position. A drawback to this type of seating bench and folding bed combination is that the bench does not have the option of being folded up, down or otherwise out of the way when the bed is in the upright position. Consequently, the folded bed takes up more floor space and is not as versatile for purposes of compact storage of the bed.




A folding bed may further include storage space within or adjacent to the storage space allocated for the folding bed. U.S. Pat. No. 6,212,710B1 illustrates cupboards included in a folding bed cabinet. U.S. Pat. No. 5,522,102 discloses an enclosure unit partially surrounding and removable from the lower portion of an upright bed frame. These designs have various constraints including, for example, size, permanency, easy of access, and manufacturability.




It can be seen then that a new and improved folding bed is needed that overcomes the problems with the prior art. An improved folding bed should provide a more versatile folding seat that requires less overall floor space when the bed is in the upright storage position. An improved folding bed should also provide an adjacent storage space with advantages over the prior art. The present invention addresses these as well as other problems associated with folding beds.




SUMMARY OF THE INVENTION




The present invention is directed to a folding bed, and in particular to a folding bed having a folding bed assembly and an independently actuated folding seat assembly. The bed assembly and seat assembly are supported on a frame that may be utilized with a storage compartment or locker and incorporated into a cabinet or a recess in the wall or may be self-standing and supported on casters, providing for easily moving the bed between various locations.




The bed assembly includes a mattress mounted to a bed frame and retained with a strap. Folding legs extend outward from the extended edge of the bed frame and provide support in unfolded position. The bed assembly folds along one of its sides between an unfolded use position wherein the mattress and bed frame are substantially horizontal for sleeping, and a folded storage position, wherein the mattress and bed frame are substantially vertical. The bed assembly includes a linkage having a link connecting the support frame to the folding legs. The bed frame pivots near a center portion at each end of the bed frame on the support frame. The bed linkage automatically retracts and extends the folding legs as the bed is folded and unfolded. A counterweight and/or one or more gas springs may be utilized to balance the bed so that the folding may be easily accomplished with minimal effort.




The bed assembly also includes a lock with a handle mounted in the bed frame and flush with an outer surface of the bed frame in a non-actuated position. The lock is depressible to actuate a shaft extending through the bed frame to the inner side of the bed to engage one of two brackets, each configured for receiving the extended shaft, A first bracket receives the shaft in the unfolded use position and a second bracket receives the shaft in the folded stored position.




The seat assembly includes a seat back mounted to an underside of the bed frame and a seat bottom extending outward from a strut extending outward from an underside of the bed frame transverse to the plane of the bed frame. The seat bottom folds between a position substantially flush against the seat back and an extended use position. Folding legs mount to a seat frame near an outer edge to provide sufficient load capacity to support several persons on the seat. The seat linkage includes a link connecting the legs to the support frame so that the legs automatically retract in the storage position and extend in the use position. A lock mounts to one of the folding legs for the seat and includes a spring-loaded actuator handle and an engagement pin. The engagement pin extends through the leg to engage the bed frame when the seat is in the folded stored position. The lock prevents accidental folding of the seat assembly.




The present invention may also include a cabinet covering the mechanisms as well as the bed assembly and seat assembly. It can be appreciated that the present invention provides full access for cleaning the floor and minimal extension outward with side folding and a balanced folding mechanism mounting from an upright portion of the wide base of the support frame.




These features of novelty and various other advantages that characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for a better understanding of the invention, its advantages, and the objects obtained by its use, reference should be made to the drawings which form a further part hereof, and to the accompanying descriptive matter, in which there is illustrated and described a preferred embodiment of the invention.

DETAILED DESCRIPTION




Referring now to the drawings, particularly

FIG. 1

, there is shown a folding bed, generally designated


20


. The folding bed


20


includes a folding bed assembly


22


and a folding seat assembly


24


that are actuatable independently of one another. The bed


20


is supported by support frame


26


having a wide base with a vertical portion extending upward there from. The bed


20


also may include a storage compartment or locker


90


situated behind the bed and against which the bed assembly


22


folds when in the storage position. The storage compartment


90


may have sliding doors to provide easy access with room to keep bed linens, pillows and other accessories at a convenient location. Although the present invention is freestanding on the support frame


26


, it could also be mounted into a wall and pulled outward from there. If freestanding, the bed


20


typically includes a cabinet


92


receiving the bed assembly


22


, the seat assembly


24


, and the storage compartment


90


. The bed assembly


22


folds between the use position shown in FIG.


1


and the storage position shown in FIG.


2


. Unlike typical prior art wall beds, which fold from one of their ends, the bed


20


has the bed assembly


22


fold along one of its sides. The seat assembly folds between a storage position shown in

FIGS. 1 and 2

and a use position shown in FIG.


3


.




The bed assembly


22


includes a mattress


30


supported on a substantially horizontal bed frame


34


. A strap


32


extends around the mattress


30


and maintains it in position against the bed frame


34


when folded and unfolded. The configuration of the bed assembly


22


is such that the mattress


30


is never folded, unlike the typical sleeper couch. When unfolded, two legs


36


support the bed frame


34


, one at each of the corners at the extended edge of the bed frame


34


.




As most clearly shown in

FIGS. 4-6

, the bed assembly includes a folding linkage


40


which facilitates folding of the bed assembly


22


from an unfolded use position, as shown in

FIG. 4

, through an intermediate position, shown in

FIG. 5

, to a folded storage position, shown in

FIG. 6

, and back. The bed assembly


22


folds so that the bed frame


34


is substantially horizontal in the unfolded use position shown in

FIG. 4

, and substantially vertical in the folded storage position, shown in FIG.


6


. The folding linkage


40


mounts on the support frame


26


with a tab


46


extending horizontally from the rectangular portion


28


, acting as a linkage support. A main pivot


44


of the bed assembly


22


is positioned just above and at an outer end of the linkage support portion


28


of the frame


26


. A first link


42


pivotally mounts to the tab


46


on one end and to a folding leg


36


at the extended end. Each of the legs


36


also pivotally mounts to a side of the bed frame


34


near an outer edge of the bed frame. As shown in

FIG. 5

, as the bed assembly


22


is unfolded, the linkage


40


rotates the legs


36


outward from a position beside an end of the bed frame


34


. To facilitate folding, in a preferred embodiment, the bed frame


34


includes a counterweight in the frame to provide balance about the pivot


44


. A gas spring


62


mounts between the support frame


26


and the bed frame


34


. Although one gas spring


62


is shown mounted at one end of the bed


20


, various gas springs of various sizes and having various damping characteristics, or combinations of two or more gas springs


62


may be utilized in the present invention at one or both ends of the bed


20


. As shown in

FIG. 6

, when the bed


20


is positioned with the bed assembly


22


in the folded storage position, the bed linkage


40


automatically positions the bed frame


34


at a substantially vertical position. In addition, the folding legs


36


of the bed assembly


22


are also retracted to a position extending outward from and collinear with an edge of the bed frame


34


.




As shown in

FIG. 6

, further unfolding moves the bed assembly legs


36


to a substantially vertical position transverse to the bed frame


34


. Moving the bed assembly


22


from an unfolded position to a folded position moves the bed assembly legs


36


back to their substantially vertical stored position, retracted against the bed frame


34


. When fitted with casters


38


, at the folded position, the bed


20


is free to me moved and may be easily rolled from location to location.




Referring now to

FIGS. 6 and 7

, the seat assembly


24


includes a seat back


70


and a seat bottom


72


that folds between a use position and a storage position. Seat back


70


is mounted substantially flush against the underside of the bed frame


34


. The seat back


70


and seat bottom


72


may be cushioned but may also be hard surfaces. In addition, the cushions may be removable from the seat assembly


24


. It will be appreciated that in the unfolded position, the seat assembly


24


provides comfortable seating and support for the backs of several seated users. Moreover, the seat assembly


24


includes folding seat legs


74


positioned near the extended edge of a seat frame


76


from the seat bottom


72


so that rigid support is provided. With the legs


74


and the support frame


26


, substantial load capacity is provided to accommodate seating of several persons on seat assembly


24


.




In addition, as shown in

FIG. 9

, the shaft


56


inserts into an orifice in a second receiver bracket


60


, positioned at the base of the support frame


26


. When the shaft


56


is inserted into the orifice of the second bracket


60


, the bed assembly


22


cannot be moved from the storage position, shown in

FIGS. 2 and 6

. This prevents accidental unfolding of the bed assembly


22


and provides for a safer secure folding bed. In either position, the lock assembly


50


is easily released by depressing lock handle


52


that is flush with an outer portion of bed frame


34


. This configuration minimizes accidental release of the lock assembly


50


and also eliminates an extended element, which may pose a safety hazard.




Referring now to

FIGS. 6 and 7

, the seat assembly


24


includes a seat back


70


and a seat bottom


72


that folds between a use position and a storage position. Seat back


70


is mounted substantially flush against the underside of the bed frame


34


. The seat back


70


and seat bottom


72


may be cushioned but may also be hard surfaces. In addition, the cushions may be removable from the seat assembly


24


. It will be appreciated that in the unfolded position, the seat assembly


24


provides comfortable seating and support for the backs of several seated users. Moreover, the seat assembly


24


includes folding seat legs


74


positioned near the extended edge of a seat frame


76


from the seat bottom


72


so that rigid support is provided. With the legs


72


and the support frame


26


, substantial load capacity is provided to accommodate seating of several persons on seat assembly


24


.




The seat frame


76


pivotally mounts on a seat linkage support strut


82


extending transversely from an underside of the bed frame


34


. The seat legs


74


pivotally mount to the seat bottom frame


76


at an extended end. A link


84


mounts to a tab extending forward from the linkage support


28


of the support frame


26


and bends slightly to pivotally mount to the seat legs


74


. The seat linkage


78


facilitates folding between the storage position shown in FIG.


6


and the unfolded use position shown in FIG.


7


. Moreover, the linkage


78


allows for folding of the seat assembly


24


with the bed assembly


22


as shown in

FIGS. 4-6

. The various elements of the seat linkage


78


remain in the substantially same alignment and do not pivot relative to one another when the bed assembly


22


folds, with the exception of the link


84


that folds from a substantially vertical upward extending position shown in

FIG. 6

, to the outward horizontally extending position shown in FIG.


7


.




Referring again to

FIG. 2

, the seat assembly


24


includes a lock


88


. An engagement pin of the lock


88


extends from one of the seat legs


74


through the bed frame


34


to prevent movement of the seat assembly


24


relative to the bed frame


34


. A spring-loaded actuator handle


80


is depressible to release the seat assembly


24


and allow folding of the seat assembly


24


. The actuator handle is simply pivotally mounted to seat leg


74


and biased toward an engaged position. Pivoting of the actuator handle


80


retracts the pin of the lock


88


and allows unfolding of the seat assembly


24


.




Referring now to

FIG. 10

, there is shown a second embodiment of a folding bed, generally designated


100


. The folding bed


100


is similar to folding bed


20


, but includes a further housing


102


extending over the bed assembly and seat assembly so that a cabinet-type appearance is presented. The cover


102


may take on various configurations including a roll top-type configuration sliding on tracks, a folding cover with one or more panels pivotally mounted, or other well know cover arrangements. The cover


102


moves between a position covering the seat assembly


24


and bed assembly


22


and is removed or retracted for easy access and use.




Referring to

FIG. 11

, there is shown a third embodiment of a folding bed, generally designated


200


. The folding bed


200


is similar to folding bed


100


, with a housing


202


extending over the bed assembly and seat assembly so that a cabinet-type appearance is presented. As with bed


100


, the cover


202


may take on various configurations including a roll top-type configuration sliding on tracks, as shown. Folding bed


200


also includes end storage compartments


204


at either end of the bed


200


. The compartments


204


include front access doors


206


providing easy direct access for storage of pillows, bed linens and other accessories. The compartments


204


may also include top access rather than front access and a single compartment at one end of the bed, rather than a pair of compartments my be utilized, depending on needs and available space. The end compartments


204


may also be used with the rear storage compartment shown in the first embodiment. The bed


200


is shown permanently mounted directly to a wall. It can be appreciated that the first two embodiments of the folding bed,


20


and


100


, may also be incorporated into a wall. In addition, the bed


200


may be configured as a stand-alone unit.




Although the present invention has been shown with both a bed assembly


22


and a seat assembly


24


, it can be appreciated that the folding bed assembly may be utilized without the folding seat assembly


24


. The present invention provides a sturdy economical folding bed that folds along its side rather than an end. Moreover, the folding bed may be incorporated into rooms and permanently inserted into a wall of the room or it may be utilized as a mobile unit. The support frame


26


may be fitted with casters that provide easy movement of the folding bed


20


. With the bed


20


having three positions, it provides great versatility to any room that incorporates the folding bed in its design. In a first position with the bed assembly


22


folded and the seat assembly


24


folded, the folding bed


20


provides maximum floor space. With the bed assembly


22


folded and the seat assembly


24


unfolded, the folding bed


20


provides bench type seating for several persons, requiring minimal floor space. In a third position with the bed assembly


22


unfolded, the folding be


20


provides a bed in the same space.




It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
