Patented June 28, 1932 PATENT OFFICE WILLIAM L. BRYDEN, OF CLEVELAND, OHIO I ADJUSTABLE RECLINING CHAIR Application filed November 14, 1929i Serial'No. 407,070.

' My invention relates to adjustable reclining chairs, and more especially to this type of chairs having a supporting web of canvas or other suitable flexible materlal unsupported between the ends of the web, but affording adesirable support for invalids in particular, both in an erect or reclining position.- It is also desirably collapsible.

It is a special feature 1 that a pivoted relation between an horizontal parallelogram at the usual position of the arms,eand another parallelogram extending downward from the forward ends of the horizontal bars of the first, retains the foot rest in a substantially horizontal position, when the chair is adjusted toany position of which it is capable, and a very pleasing control of the chair is thus afforded by the pres- 7 sure of the feet on the foot rest by the 00011: ant.

While the pivoted frame of the chair is shown in the drawings in full lines as supported by cross bars intended to rest on the floor, it is my intention to provide means for suspending the frame from an overhead support, as shown in dotted lines. Either means for support may be used.

My invention consists in certain novel features which will be hereinafter fully described, then more particularly pointed out in the appended claims, and is illustrated in the accompanying drawings in which- Figure 1 is a perspective view of the chair,

Figure 2 is a central longitudinal section of the reclining chair in erect position;

Figures 3 and 10 are side elevations of the chair shown in its reclining and collapsible positions, respectively;

Figures 4, 5, 6 and 7 are vertical sections shown in the planes indicated by the numerals 44, 5-5, 6-6 and 7-7, respectively; and

Figures 8 and 9 are horizontal sections taken in the planes indicated by the lines 88 and 99, respectively. I

Fig. 11 is a side elevation of the chair.

Fig. 12 is a perspective view of the chair, shown in a vertically suspended position.

As shown in full lines, the adjustable back of my construction here shown in a substantially erect position;

ends of the outer bars 16 are further conof the chair comprises laterally spaced vertically inclined bars 5 having their upper ends connected by a transverse rod 6. The lat-. ter affords means for supporting the upper end of the canvas web 7 which may be readily folded about the rod in a loop for attachinent. At points 8 intermediate the ends of these bars 5, I have pivoted forwardly extending horizontal arm bars 9 upon the forward ends of whichare pivoted the downwardly extending bars 10 by the cross pins 11, and the bars 5 and 10 are further'connected by horizontal bars 12 whose forward ends are pivoted to the cross pins 13 which are intermediate the ends of the bars 1-0, the bars 66 12 being pivoted at a point somewhat spaced from their rearends, as at 14, to the lower ends of the bars 5, at said points by suit able pins. ,7

The above construction will thus be shown to positively retain bars 5 and 10 in parallelism, by reason of the positioning of the bars 9 and 12 in parallelism, this being a desired relation of these very important parts.

7. If the chair is intended torest upon a plat 7 5 form or floor of any kind, I will support it upon a pair of X-standards comprising bars 15 and 16, the upper ends of eachof thesebars 15 and 16 being pivoted to the corresponding pivoted bars 5 and 10,respectively', of the 30 corresponding side of the chair frame. The pivotal connections of the standards to the 7 bars 5 and 10will' be at the points-17 and 18,

respectively, intermediatethe points 8 and 14 of-one, andth'e pivots 11 and 18 ofthe'other. 35

Each pair of the standards thus pivoted, comprises the bars15 and 16 which are detachably braced'against each other by blocks 19 securely fastened on the face of each bar, as by nails or screws, the block on either bar pressing downward against the upper edge of the other bar, as shown clearly in Fig. 1 of the drawings. The bars of each standard may readily collapse by swinging on their pivots, when the chair is to be folded up as shown in Fig. 10. a

The swinging frame will itself serve as a cross bracefor the two standards. The lower n'ected-by a rod 22having pins enteringthe' till bars 16 and secured to them in the manner shown in Fig. 8. The block fixture is shown well in Fig. 6.

A foot rest comprises a flat board 23 whose ends are securely attached to parallel levers 24. The latter are'pivoted at their rear ends 26 and intermediate their ends at 25, to the lower ends of bars 27 and 10, respectively, so that the latter bars are maintained in parallelism, and the upper ends of bars 27 are pivoted at points 28 on the bars 12, so that the bars 24 remain parallel to the bars 9 and 12, just as the bars 5, 10 and 27 are always parallel. The foot board 23 is mounted upon a forwardly extended end of the levers 24, and therefore may be adjusted vertically, but is always maintained in a nearly horizontal plane.

Since the lower bars 12 are positioned somewhat inwardly from the vertical plane in which the bars 9 are located, and the standards 15 and 16 remain spaced quite outside of the plane of the pivoted bars, I have provided spacer bars 29 extending from the pivot 11 to the pivot 18'and positioned between the upper end of the bars 10 and the forwar ends of the bars 9 and 16, as is well shown in Figs. 1 and 4. For a similar reason, I have provided rings 30 upon the pivots 8 between the bars 5 and 9, as shown in Figs. 1 and 5.

The X-standards are nowhere connected with the main frame of the chair, except at the pivots 17 and 18, and these pivots remain spaced at a substantially constant distance apart. It has been found advantageous to extend the rear ends 31 of the bars 12 beyond the pivots 14, whereby this extension 31 may serve as a means for preventing the top of the chair from falling below a desired limit, as will be evident from the view in Fig. 3 of the drawings. While I have shown the foot board 23 mounted upon an inclined edge 32 of the bars 24, it need not be inclined to the length of such bars, nor inclined at any particular angle to them.

- In some cases it may be desirable to suspend the chair from an overhead support of some kind, and I have shown in. Fig. 12, cables 33 so suspended, and have illustrated eye fixtures 34 which are located at the pivots l7 and 18, and may serve the common purpose as such pivot pins and the means for attaching the cables 33. Neither means of support need be retained. while the other is being used.

It will be seen from the drawings and the foregoing description that my chair comprises a pair of laterally spaced articulated frame members, each of which comprise the substantially horizontally extending bars 9, 12 and 24, which are pivotally connected to the vertically inclined bars 10, 27 and 5, thereby forming two parallelograms, one of which is formed by the horizontal bars 9 and 12 and the-vertically inclined bars 10 and 5 the other of which is formed by the vertically inclined bars 10 and 27 and the horizontal bars 12 and 24. These transverse frame members are joined together by suitable transverse rods 6,-

and 13 and the foot rest 23, thereby forming an articulated structure which supports the canvas web 7 heretofore described.

Whatl claim as my invention and desire to secure by Letters Patent is- A pivotally adjustable and collapsible reclining chair comprising in combination, a stationary supporting frame including a pair of spaced X-frames, a swinging frame pivote-d upon the upperends of said X-frame and comprising laterally spaced members connected by transverse rods, and a flexible memher having its ends suspended from the said rods, the said X-frames comprising cross bars each provided with a supporting block detachably resting upon the upper edge of the other bar, and the swinging frame including in each of said spaced members three parallel and spaced horizontal bars pivotally connected with parallel vertically inclined bars,

whereby the swinging frame may swing back-- ward to nearly horizontal position, and it together with the X-frames may be swung forward to collapsed position.

In witness whereof, I have hereunto set my hand this 8th day of November, 1929.

WILLIAM L. BRYDEN.
