FOLDING BED.

Appflication filed November 20, 1919. Serial 1W0. 339,390.

To all wiz am it may concern Be it known that 1, WILLIAM L. MURPHY, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented a new and useful Folding Bed, of which the following is a specification.

My invention relates to folding beds.

An object of the invention is to provide a folding bed embodying an improved foot frame and means for mounting'the same.

Another object of the invention is to provide an improved head frame and mounting therefor.

Another object of the invention is to provide a bed capable of being folded to adapt it to be moved through a doorway, and having in the unfolded position stable head and foot frames having the appearance of the head and foot frames of an ordinary bed.

The invention possesses other objects and features of advantage, some of which, with the foregoing, will be set forth in the following description of the preferred form of my invention which is illustrated in the drawings accompanying and forming part of the specification. It is to be understood that I do not limit myself to the showing made by the said drawings and description, as I may adopt variations of the preferred form within the scope of my invention as set forth in the claims.

Referring to the drawings:

Figure 1 is a side elevation of the bed unfolded for use. Figure 2 is a side elevation of the folded bed. Figure 3 is a vertical sectional View taken longitudinally of the bed. Figure 4 is a vertical sectional view of a portion of the head frame and mounting. Figure 5 is a plan view of a part of the bed supporting frame.

The bed of my invention comprises a supporting structure formed of the end members 2 connected by the angle iron 3, and the four sided frame 4 which is made of cylindrical tubing. Brackets 6 and 7 are bolted to the top and bottom respectively of the frame 4, and are pivotally supported on fixtures 8 and 9 respectively, secured. on the edge of a closet door casing 10, so thatwhen the bed has been folded into a vertical position the supporting structure may be turned through the door into the closet. In order to permit transverse adjustment of the frame 4: upon the brackets, the apertures 11 therein, through which the fastening bolts 12 pass, are elongated as best shown in Figure 5.

The bed frame comprises side rails 13 on the head end of which fittings 14: are fixed. An angle iron 16 rigidly connects the fittings and provides a transverse bar towhich the wire fabric 17 is attached, the foot end of the fabric being attached to a similar baror angle iron 18 connecting the fittings 19 fixed at the foot end of the side rails.

The head frame of the bed is in two parts and consists of an upper frame 21 pivotally connected by the knuckle joints 22 to the lower frame 23 which is bolted rigidly to the fittings 14 and extends transversely across the bed frame.

Each fitting 14 is provided with a stud 24 journaled in the upper end of a link 26, the lower end of which is pivotally mounted on the'pin 27 in the front lower portion of the supporting frame 2. The fittings are also each provided with a stud 28 adapted to en gage the rear face of a guide 29 extending upwardly from the front end of each frame 2. The upper end of each arm is formed with a sloping shoulder or ledge 31 upon which the studs 28 seat when the bed is lowered to the horizontal position. Thus the links 26 carry the weight of the bed during its movement to and from its horizontal position and the guides 29 control the character of that movement, permitting a bodily forward movement of the bed to permit the seating of the studs 28, so that ressure on the head end of the bed exerted ownwardl y will not lift the foot end.

A transverse bar 32 extending across the head end of the bed, is connected to the fittings 14, and a series of tension springs 33 are interposed between this bar and the transverse bar 3 to counterbalance the weight of the unbalanced portion of the bed forward of the links 26.

Legs 34 for supporting the foot of the bed when it is turned down are pivoted to the side rails 13, and are rigidly connected b a rod 36 on which a lever arm 37 is fixe A link 38 is pivotally attached to the lever arm at one end and to the transverse bar 3 at the other end, the proportion and arrangementof parts being such that on raising the bed into the vertical position, the link 38 draws the legs 34 into parallelism with the side rails 13, and on lowering the bed, extends the legs to limit the downward movement of the bed. This limitation by the legs 34 of the downward movement of the bed is intimately connected with the functioning of the upper head frame 21 and its controlling mechanism. It is desired that the upper frame which of course lies in a substantially vertical plane when the bed is in its horizontal position as seen in Figure 1 shall retain the same vertical position and be substantially parallel to the plane of the wire fabric when the bed is raised as seen in Figure 2. In the latter case, the upper head frame acts as a retainer for the pillows and head end of the mattress so that the bedding is not disarranged by the movement of the bed. An eye bolt 41- is disposed in the center of the top member of frame 4, passing through a slot in the bracket 6 so that adjustment of the bracket is not interfered with. Pivoted to the eye bolt is a link 42-. which at the other end is bifurcated and provided with a roller 43 adapted to engage the guide 44 vertically fixed on the rear side of the upper frame. The proportion and arrangement of the parts is such that when. during the lowering of the bed. the legs'34 touch the floor. the link 42 is at the lower extreme of its movement on the guide 44 and retains the upper frame snugly against the stops of the. knuckle joints 22, thus maintaining the head frame securely in position. When, during the raising of the bed, the upward movement is halted by ongagement of the screws 46, adjustably set in the links 26. with the front edge of the guides 29. the link 42 is at the upper extreme of its movement on the guide 44, thus retaining the upper frame in the desired vertical position. The link 42 therefore permits the rise and fall of the upper frame 21 during movement of the bed. but insures the substantially vertical position of the frame,-and draws it tightly against the stops of the knuckle joints to give it rigidity when the bed is in position for use. The legs 34 provide the positive stop to move ment of the bed which-is necessary to prevent the breaking of the knuckle joint or the distortion of the frame 4, which would occur if the foot end were lowered too far. Means are arranged at the lower end of the bed for providing a foot frame of standard type which supports part of the weight of the bedand also serves as a clamp to retain the mattress and bedding in position when the bed is turned up. A foot frame of standard design comprising the vertical members or legs 47 connected by the transverse top rail 48 is mounted on the side rails 13 by links 49 and 51 at each side, pivoted as shown in Figure 1, so that the foot frame may be turned up upon the mattress in a position substantiall parallel to the side rails, as shown in Figure 2. The lower-link 51 is formed preferably with a bend inter-median: its ends, and a stop 52 is formed on each ['11- ting 19 to limit the movement of the link and the foot framewhen it is moved to upright position after the bed is lowered. Tension springs 53 are attached to the links 51 and the side rails 13. These springs, pulling on the link 51 in the unfolded position of the foot frame, as shown in Figure 1, keep the foot frame tightly against the floor. and to an amount equivalent to their tension support the weight of the bed. The stops are so placed that they prevent: the links from being pulled under the bed frame to far, and with a level floor the links 51 are i engaged with the stops. the bottoms of the foot frame are seated firmly on the floor and together with the legs 34 support the foot end of the bed. The structure thus ar ranged provides a stable and relatively rigid foot frame comparable to that of an ordinary bed.

Turning up the foot frame moves the springs 53 past the pivot of the links 51 and draws the foot frame tightly against the bedding and mattress as shown in Figure 2.

Operatz'0n.-Assumin g the bed illtllO open position shown in Figure 1, the bed is folded by turning up the foot frame to clamp the mattress and bedding tightly against the spring 17. Small upward pressure on the foot end, then unseats the studs 28 and permits the bed to pivot and move lmekwardly on the links 26, the knuckle joints 22 turning and the upper head frame simultaneous ly moving downwardly and rearwardly and the legs 34 folding toward the rails 13 until the parts are in the position shown in F igure 2. The bed is then swung on its pivoted brackets 6 and 7 through the closet: doorway to the opposite side of the casing.
