DUAL BED AND CONVERTIBLE COUCH COMBINED Filed April 5, 1961 2 Sheets-Sheet 2 Donald B. Salinger INVENTORv 3,047,885 DUAL BED AND CONVERTIBLE COUCH COMBINED Donald B. Bolinger, Bloomington, Ill. (305 Normal Ave., Normal, Ill.) Filed Apr. 5, 1961, Ser. No. 100,943 4 Claims. (Cl. 5--9) This invention relates to certain new and useful improvements in convertible multipurpose furniture which is expressly constructed and uniquely designed to function with requisite nicety in a room of limited size and where available space is at a premium and compactness and convenience is both desirable and necessary, and has to do with an original concept and structural adaptation which may be broadly categorized as a dual bed and couch combined.

The present invention is designed and adapted for use in quarters wherever extensible and retractible bed and lounging couch facilities are customarily provided but was evolved and produced primarily, but not necessarily, for practical use in college and university dormitories, hotels, motels and the like where groups of students and others assemble and congregate and have need for at least a couple of beds and a sitting and lounging couch or sofa, as the case may be. Many other places of installation or use too numerous to mention are under consideration but will not be dwelled upon here for, obviously, the concept to be dealt with is not so much where the invention is to be used but what the invention itself is and how the objectives are to be acceptably accomplished. V

Briefly, the invention pertains to a novelly constructed relatively stationary floor-supported high-level bed unit,

and a companion retractible and projec-tible low-level bed unit, the latter comprising an improved caster-equipped trundle bed and having the function of a bed on the one hand and a couch, on the other hand. The first-mentioned unit is such in construction and purpose that it combines with a room wall and adjacent underlying floor to define a stall-like stowage space for the trundle bed. The latter bed, when in its stall is not only conveniently out of the way to economize on floor space, it is also hidden from view. Also, when it is fully withdrawn and amply extended beyond the open front of the stall or storage space,

it provides a low-level bed. When shoved part-way into said space, it provides a couch.

stowage space. The top of the bolster is at a level below the level of the mattress and the bottom thereof is elevated to assume a plane above the top of the mattress on the trundle bed. It follows that the space between the bottom surate in length with the length of the open front of the of the bolster and the floor is such as to allow the trundle bed to be retracted or extended and when it is extended part way, the trundle bed then converts to a couch or sofa and the bolster constitutes a backrest, said bolster being 3,047,885 lfatented Aug. 7, 1962 suitably padded and upholstered to function to advantage in the role of a comfortable backrest.

Further novelty is predicated on the aforementioned tfirst-named bed unit in that it is characterized by a pair of vertical spaced parallel wooden or equivalent panels.

These panels have floor engaging feet at their lower ends and when the rearward vertical edges of the panels and rearward lengthwise frame member of the bed springs are both against the wall a neat and practical enclosure constituting the aforementioned stowage or storage space is had. Furthermore these panels facilitate mounting the box-like or cabinet portion of the bolster. Inaddition, the frame of the bed spring is suspended between the upper portions of the panels.

A further improvement resides in the aforementioned construction wherein the bolster comprises a walled cabinet for storage of pillows and miscellaneous small articles. Then, too, the front wall of this cabinet is hingedly mounted and equipped with cushions and constiuttes a satisfactorily inclined backrest.

With respect to the trundle bed this is proportioned so that when it is in the stowage space it is completely onclosed. When it is fully extended or partly extended to serve either as a bed or a couch it is caused to stay put in these respective positions by way of weight responsive friction brake controlled and held front rollers preferably but not necessarily of a type shown in my Patent 2,942,698 identified as Weight Operated Wheel Brake.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein likenumerals refer to like parts throughout, and in which: FIGURE 1 is a view in perspective of the multipurpose or dual bed and convertible couch combination showing the extensible and retractible trundle bed in its couchforrning position;

FIGURE 2 is a view on a larger scale taken centrally through the structure seen in FIGURE 1 and in which the details and their particular construction and arrangement in association are clearly illustrated;

FIGURE 3 is a top plan view with portions broken away and other portions appearing in section and elevation;

FIGURE 4 is a front elevation with a portion of the structure at the right broken away to illustrate certain otherwise hidden details; and

FIGURE 5 is an exaggerated fragmentary sectional elevational view showing a slight modification in the front construction of the aforementioned bolster.

With attention directed to FIGURES 1 to 4, inclusive, the relatively stationary high level first bed unit is denoted generally by the numeral 8. The companion low lying second bed unit (or trundle bed) is denoted generally '(FIG. 2) by the numeral 10. The cooperating multipurpose bolster is denoted by the numeral 12.

Taking up now the means or unit 8 attention is first directed to the elevated bed spring 14. This spring supports a suitable mattress 16. The spring itself is incorporated in the frame structure and this frame structure embodies a pair of spaced parallel forward and rearward angle irons 18 and 20 fastened securely between the upper en ages?) corner portions of the end members or panels 22 at points below the upper edges of said panels. These panels are preferably of wood and are suitably decorative as shown in FIGURE 1 and the lower corner portions are provided with suitable floor engaging and steadying feet 24. The numeral 26 designates a board or a suitable brace which spans the rear edge portions of the lower portions of said panels with its end portions secured thereto by angle brackets or the like 28. This part 26 serves not only as a rigidifying brace, it provides a limit stop for the left to right travel of the trundle bed as will be evident from FIGURE 2. The aforementioned bolster is a component part of this unit 8. The bolster is of hollow boxlike or cabinet construction and the cabinet part as a unit is denoted by the numeral 30 in FIGURE 2 and it will be observed that the spaced parallel end walls 32 abut the interior surfaces of the legs or panels 22 and are bolted thereto as at 34-. The cabinet spans and bridges the full length of the open front of the unit 8 and the top wall 36 is disposed on a plane above the spring 14 but below the top of the mattress 16. The bottom wall 38 is disposed at a predetermined plane which allows for proper clearance of the unit Ill. The vertical wall 40 of this construction may be made of one piece or more with the same hingedly mounted on the top portion as at 42 thus providing a closure and cover. The exterior surface of the wall 46 is suitably padded and upholstered as at 44 to provide cushions thus defining a cushioned inclined backrest in addition to an article storing cabinet. may be best described as a low level trundle bed. It comprises a suitable rectangular metal or equivalent horizontal frame 46 provided with a bed spring (not detailed) and serving to support a mattress 48. The end frames supporting the main top frame 46 are denoted at 56 and include horizontal frame members 52 which are equipped with depending casters, wheels, rollers or the like. Preferably the inward or rearward wheels 54 are mounted for free rotation on depending yoke-type brackets 56. On the other hand the front wheels are of special construction. Each front wheel is denoted at 58 and is mounted for free rotation in a U-bracket 60 integral with the free end of a leaf spring 62 whose other end is fixed at 64 to the frame member 52.. The numeral 66 designates a friction brake shoe or fixture which is of U-shaped form and is fastened in place on the frame member as at 68, the curvate inclined bight portion 70' being opposed to the periphery of the roller or wheel and providing a friction brake surface. It is to be mentioned here that this construction and arrangement serves to provide braking action to the wheels in response to the application of a load beyond a predetermined limit when imposed on the mattress. This self-braking and trundle bed holding means is covered, specifically, in my Patent No. 2,942,- 698. As pointed out in the stated patent the construction and arrangement of the roller is such that the locking result is accomplished automatically, that is, in response to the weight load of the occupant or occupants using the mattress 48 either as a bed or couch as the case may be. When the weight is lifted the spring means 62 automatically functions to release the brake and to allow the trundle bed to be shoved in or out of the stowage space in a seemingly obvious manner.

Although the views of the drawing do not show the trundle bed in its completely housed out-of-the-way position, it will be understood that in practice when the righthand edges of the panels 22 are back against a-vertical wall or an equivalent surface, the panels 22, overlying mattress and spring combine with the floor in defining the aforementioned stowage space. It follows that when the trundle bed is shoved into this space (not shown) its travel from left to right in FIGURE 2 is limited by the brace 26. In this position the two beds are one above the other and are of approximately corresponding size and proportion so that the trundle bed is in a hidden out- The receding or projectible and retractible unit 10 A. of-the-way compact and convenient position but is ready to be withdrawn whenever necessary or desirable. It will also be obvious that the trundle bed can be pulled completely out of the stall-like stowaway space and in fact beyond the bolster 12 to serve as a bed thus providing upper and lower beds for individual occupants. When the parts are in the arrangement depicted in FIGURES 1 and 2, for example, and with the trundle bed halfway out, a convenient couch for lounging and sitting purposes is provided. At this time the padded bolster provides a practical backrest. The friction brake rneans comes into play to hold the trundle bed in either its bed position or couch position as is obvious.

In FIGURE 5 a slightly different construction is shown but basically the arrangement is the same as already described. Briefly one endpanel is denoted at 72, the spring means at 74, the spring 76 being mounted on the rails 7 8 supported between the end panels. The mattress is denoted at 80. The box-like cabinet is here denoted at 82 and the end walls 84 are bolted or otherwise fastened at 86 to the adjacent panel. Here the front lid or cover 88 is hinged along the bottom by hinge means 90 to the bottom wall 92. The upper edge 94 is provided with a ball-type detent 96 engageable with keeper clips 98 just below the top wall 100. No further description on this aspect or concept would appear to be necessary here.

it will have been noted that the upper end portions of the end panels project to a plane above the plane of the bed spring 14- and rails 18 and 2t and that the upper portion of the bolster spanning the space between the end panels 22 also projects to a plane corresponding with the upper projecting edge portions of the panels with the result that these several coacting edge portions define a confining rim for the lower or basal portion of the mattress 16. The brace 26' stabilizes the end panels at the rear of the unit 8 while the forwardly and outwardly projecting bolster rigidifies the forward upper portions of the panels consequently providing a novel structural unit or entity 8. This unit lends itself admirably well to cooperation with the projectible and retractible trundle bed. The invention may be effectively and satisfactorily used in homes where two youngsters must sleep in one room and where twin beds occupy so much floor space that the use of study desks or other furniture would be prohibited. The trundle bed, being only 29 inches high at the highest point, allows easy access for the children sleeping in the top bed without danger of falling out, such as in present day bunk beds, and the lower bed unit can be pulled out during the day for seating purposes or to serve as a flat surface upon which the children may sit and color or study. The essence of the concept resides in the coordinate arrangement and unification of the several component parts which cooperate and provide two beds, one stationary and the other one movable. The movable bed may be stored in an out-of-theway position in its stall-like enclosure when not in use. In addition it may be fully withdrawn from the enclosure and used as a bed or it may be located in an intermediate position with the median portion thereof underlying the bottom of the boltser and an approximate half-portion projecting beyond the bolster to serve as a couch, whereby to thus provide multipurpose convertible furniture which lends itself to practical use primarily, but not necessarily, in living quarters where space is at a premium. Its presence in the room makes it possible to dispense with other space-consuming units, makes for compactness and convenience and reduces the cost of installations and minimizes the need for services of attendants, repairmen and serves the purposes for which the invention was contrived and is being successfully used.

It is believed that a careful consideration of the specification in conjunction with views of the drawings will enable the reader to obtain a clear and comprehensive understanding of the overall subject matter, the features and advantages and the advantageous results which are capable of being accomplished when using the invention.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
