fig1 illustrates a convertible bed - sofa apparatus 10 which can serve as a sofa in the configuration 12 , and which can be converted into two beds shown in fig2 and 3 at 14 and 16 . in the sofa configuration 12 ( fig1 ), the apparatus includes a highly - decorative frame assembly 18 which may include primarily enamelled parts 20 with polished brass fittings 22 . the frame assembly includes a pair of end frames 24 , 26 and a back frame 28 whose opposite ends are connected to the end frames . a pair of elongated mattresses 30 , 32 and a pair of elongated mattress supports 34 , 36 are arranged in a stack , with the end frames 24 , 26 at opposite ends of the stack and a back frame 28 lying beside one side of the stack . the topmost mattress 30 is intended to be sat upon in the sofa configuration of fig1 . the topmost mattress support 34 is supported at locations 40 onto the end frames , so it can support the topmost mattress . the bottommost mattress 32 and mattress support 36 are stored on the floor under the top mattress support . a group of decorative pillows 37 support the back of a sitting person . the bottommost mattress support 36 can be a pop - up bed which can roll out from the rest of the sofa and which can pop up to support a mattress a distance above the ground . both mattresses 30 , 32 are of the standard twin - bed size ( 371 / 2 &# 34 ;× 74 &# 34 ;) and two beds can be provided by merely sliding out the lower mattress support and lower mattress and raising them into a second bed . the sofa itself can serve as the other bed , with the back frame removed to provide a more bed - like appearance . however , the second bed formed by the second mattress 32 and a pop - up second mattress support at 37 , will not have a decorative appearance . if the two beds are to be used for an extended period , the second bed may detract from the appearance of a room containing it . in accordance with the present invention , substantially all of the highly - decorative frame assembly 18 is used , so as to provide two beds that both have a highly - decorative appearance . this is accomplished by constructing the back frame 28 so it can be divided into first and second opposite sections 42 , 44 . in the sofa configuration , the two sections are held in alignment by a pair of splices 46 , 48 . in this example , each splice is formed of a tube with an enamelled middle portion that matches the enamelled coating on the rest of the back frame . as shown in fig4 the splicing element 47 is detachably held by fasteners 49 to the ends of the back frame sections , in a manner that permits disassembly . when these splices are disassembled so the back frame sections are separated , each back frame section can serve as a footboard . as shown in fig2 a pair of legs 50 , 52 are attached to opposite ends of the back frame section 42 to form a footboard 54 . the footboard is attached to an end of the upper mattress support 34 to support one end of it above the ground . the opposite end of the mattress support is supported by an end frame 24 . to make this transformation , it is necessary to remove the other end frame from the mattress support 34 and attach the footboard 54 formed by the first back frame section 42 and the legs 50 , 52 , in its place . the other bed shown at 16 in fig3 is similarly decorated with a headboard formed by the end frame 26 , and a footboard 55 formed by the second back frame section 44 , which is supported by another pair of legs 56 , 58 . thus , two highly - decorative and mirror - image matching beds are provided which can be used for an extended period in a room . it is possible to form the back frame so each section thereof already has legs that are present even in the sofa configuration . the length of the splices is chosen to take up discrepancies between the length of each back section ( plus legs to be attached ) and the width of the footboard of the bed . the length of each back frame section is about equal ( within a foot ) of that of the end frames , although the back frame sections are a few inches shorter until the legs are attached to them . in fig1 the lowermost mattress support 36 has a smaller ( about 4 &# 34 ; less ) length than the upper mattress support in order to easily slide thereunder . when the lower mattress support 36 is raised as in fig3 it will have adequate length to support the mattress 32 ( with only a small overhang ), but not sufficient length to extend slightly beyond the opposite ends of the mattress in order to attach to the headboard and footboard . to enable such attachment , applicant provides a pair of extension brackets 60 which attach to the end of the frame 36 and to the legs 56 , 58 of the footboard . the two beds 14 , 16 ( fig2 and 3 ) can be converted into a highly - decorative sofa by first detaching the footboards 49 , 55 from the two mattress supports , so parts of the footboards can be converted into a back frame . in fig2 and 3 the legs 50 , 52 , 56 , 58 have to be detached from the back frame sections 42 , 44 before the sections can be spliced into a back frame . an end frame such as 26 from one of the beds is attached at the location where one of the footboards 54 was removed , and the assembled back frame is attached to extend between the end frames . the mattress support 36 and mattress 32 are then stored under the mattress support 34 . in the sofa configuration , the only parts that have to be stored are the four legs 50 , 52 , 56 , 58 , the two extension brackets 60 , and miscellaneous hardware . this is a relatively small package that can be easily stored in the closet , or even under the sofa . in the two - bed configuration , the only parts that have to be stored are the splices 46 , 48 that hold the back frame sections together , and such storage is substantially negligible . thus , the invention provides a convertible sofa - bed apparatus which is highly decorative in both its sofa and bed configurations . this is a accomplished by constructing the back frame used in the sofa configuration , as two separate back frame sections that are held together in the sofa configuration and divided in the bed configuration to form part or all of the headboards of two beds . it is possible to have built - in legs on the back frame to avoid the need for mounting additional legs thereto . although particular embodiments of the invention have been described and illustrated herein , it it recognized that modifications and variations may readily occur to those skilled in the art , and consequently , it is intended that the claims be interpreted to cover such modifications and equivalents .
a convertible sofa - bed is provided , which uses the highy - decorative frame assembly of a sofa to create two beds that each have highly - decorative headboards and footboards . the sofa frame assembly includes decorative end frames and a decorative back frame , the back frame having opposite end sections that can be separated and which each have a width about equal to the width of an end frame . legs mounted on the back frame convert into a decorative footboard for not only holding a mattress support but also for providing a highly - decorative bed .
