FOLDING BED.

Application filed January 26, 1916.

To all whom it may concern:

Be it known that I, JOHN C. BEACH, a citizen of the United States, residing at the city and county of San Francisco and State of California, have invented new and useful Improvements in Folding Beds, of which the following is a specification.

This invention relates to folding beds; and has for its object to improve and simplify the construction and operation thereof.

In carrying out this object, I employ a base-plate fitted with a head piece rigidly connected thereto, a frame carried interme diate its length by pivoted suspension links depending from the corner posts of the head-frame, vertical track members on the corner posts, upon which rollers, carried by a front end-piece on the main frame, operate, counterbalancing springs between the main frame and the base-plate, and double acting springs between the corner posts and main frame, the latter operable at either extremity of movement of the main frame to cushion the same, and a frame carried upon supports extending vertically from the head frame for suspending a curtain to con ceal the folded bed.

One form which my invention may assume is exemplified in the following description and illustrated in the accompanying drawings, in which Figure 1 shows a rear elevation of a device embodyingmy invention.

Fig. 2 shows a detail perspective of a portion of the CHItZLl11CLIIYlI1,Q' frame.

Fig. 3 shows a side elevation of the front portion of the bed shown in Fig. 1.

Fig. 4 shows a similar View, with the parts in folded position.

Fig. 5 shows/a detail perspective of the swinging connecting link for one of the counterbalancing springs.

Fig. 6 shows a sectional view, taken on the line 66 of Fig. 4.

Referring now in detail to the device illustrated herewith, I have shown base-plates 10 suitably secured to the floor and carrying upright posts 11 rigidly supported by adjustable brace-bars 12, said posts forming, in connection with a cross member 13, the head-frame of the bed. A main frame 14 is pivoted at 15 to suspension links 16, the latter being pivoted at 17 to the upright posts 11. The pivot 15 forms a floating Specification of Letters Patent.

pivot on which the main frame turns. The usual folding foot-piece and supporting legs for the opposite end of the main frame are employed, although not shown in the drawings.

The front end of the main frame has upwardly projecting bracket members 18' at its sides carrying between them a front endpiece 19. Journaled upon the upper corners of the brackets 18 are rollers 20 working against vertical tracks or rails 21 fitted to the inside of each post 11 and serving to guide the main frame in its pivotal movement.

Double acting contractile coil springs 22 are provided for the purpose of counterbalancing the bed-frame in extended position and also cushioning it in its folded position. These are arranged, one at each side of the frame between the front endpiece 19 and the adjacent corner post 11, being connected to lugs 23 fixed upon the former at the top thereof and spaced inwardly from the end and to the latter by screw eyes 24: fixed tothe post midway between the extremities of movement of the lugs 23. By having the springs 22 occupy an oblique position at either side of the center of movement of the front end-piece they will be under tension during a longer period at or near the extremities of movement.

A set of auxiliary counterbalancing springs 25, preferably two in each set, is arranged between the main frame and baseplate at each side, being connected to the former by swinging lugs 26 pivoted to yokes 27 carried on the lower front end of the main frame, as shown in detail in Fig. 5, and to the latter by perforated plates 28 located on the rear side of the base-plates. In the extended position of the main frame the springs 25 are under tension, as shown in Fig. 8, and in folded position they are retracted to lie flatly upon the floor as shown in Fig. 4, on account of the swinging movement of the lugs 26. Thus the said springs 25 aid the springs 22 in the lifting movement of the main frame when the latter is in extended position.

In the operation of the device so far described, it will be seen that the main frame, when in folded position, will rest upon the base-plates 10 at its front end, at which under tension near the extremity of move-' time the springs 25 will be retracted and lie between the said end-piece and base plates, while the springs 22 will be under tension, as shown in Fig. 4. To extend the main frame for use, the operator moves the said frame outwardly from the head-frame, at which time the rollers 20 will ride upon the tracks 21, causing the main frame to be thrust bodily outward in its pivotal movement. The initial movement of the bed frame from folded position will be assisted by the springs 22 and the said springs, at

their ends where they connect to the vertically movable portion of the main frame, will be carried past their fixed connections with the corner posts and again be placed ment of the main frame in extended position.

Nhen extended the main frame is supported at its forward end by the suspension links ltiand held in proper spaced relation with the head-frame by reason of the rollers 20 engaging the guide rails 21 and the springs 25, as well as the springs 22, will be under tension at this time so that the weight of the main frame is nearly balanced.

Removably carried in sockets 29, fitted upon the head-frame, are vertical supporting rods 30 provided at their upper ends with a rodded frame 31, the latter approximately U-shaped in outline, from which is suspended, by means of rings 32, a curtain or other device 33 for concealing the bed when the latter is in folded position. Thus the article is complete in itself, furnishing its own supporting base and closure and for this reason may be positioned any place in a room without special provision being made for its reception.

While I have shown and described but one form herein, it will be understood that position, guide members between the frames for maintaining the main frame in proper spaced relation with the head-frame, and counterbalancing springs connected between the main frame and the head-frame adapted to be placed under substantially the same tension at each extremity of movement of the main frame.
