COLLAPSILBLE BACK REST.
Application filed June 19,
To all whom it may concern:
Be it known that I, FRANK M. .FAnoo, a residing at 637 in the county of Cook and State of Illinois, have invented a new and useful Improvement in Collapsible Back Rests, of which the following is a specification.
y struction of back-rest of the class designed for use at places frequented by persons desiring to sit on the ground, as on sandbeaches, picnic-grounds and the like, in supbacks in the inclined position lesirably assumed in' such sitting for comort.
In the accompanying drawing Figure 1 is a perspective view of my improved back-rest represented in its unfolded condition of use, as at a sand-beach, and provided with a canopy as a desirable but not/indispensable adjunct;
Figure 2 is a plan view of the canopy;
Figure 3 is an enlarged broken view showing the yoke device I employ for hingedly connecting together members of the frame structure;
Figure 4 and Figure 5 is a sectional view illustrating a modification for removably attaching the flexible support for the usersback to the forward legs of the frame.
The frame of the device comprises, as usual, pairs of front legs or posts 6, 6 and rear is a section on line H, Fig. 8,
legs or posts 7, 7 which should be tapered, as
shown,'toward their lower ends to facilitate insertion into the sand or ground for anchorage, the members of these pairs being flexibly connected together, as hereinafter described, and the rear members being releasably braced apart to adapt the frame to be readily collapsed vfor folding into a compact packages when out of use and for carriage, and as readily unfolded for placing into use. The rear legs should be somewhat longer than the forward ones, as represented, to produce the greater degree of inclination of the latter for comfort, by causing both pairs'to penetrate the sand or ground to substantially the same depth. For supporting the back of the user, a piece of flexible material, of suitable dimensions, preferably canvas, though it may be other fabric, is applied to the front legs 6 in either the manner represented in Fig. 1, or that repreinvention relates to an improved con and separable adjunct 1924. Serial N0. 721,009.
sented in Fig. 5. As shown in Fig. 1 the fabric (canvas) 8 has its edge-portions seamed, as by stitching, to form tubes 8 of a diameter to fit about the legs 6 to be introduced through the tubes, When the canvas may be easily adjusted to desired elevation on the legs. As represented in Fig.
5, each edge-portion of the fabric 8 is wrapped and seamed about a reinforcing rod 8 as shown of one edge-portion thereof, and each leg 6 is provided with a central bore 6 of suitable diameter and extend ing through or partly which leads a slot 6 formed longitudinally in the inner face of the leg, inforced edge-portions of'the canvas sheet inay be introduced into the bores and slots at an end thereof and slipped along the legs to bring the canvas to the desired elevation for its back-supporting purpose.
'For hingedly connecting each leg 6, near its upper end, with the end of the adjacent leg 7, I provide a U-shaped yoke 9, preferably of metal, to fit at its base or closed end about the leg 6, and fasten it in place by a headed or riveted pin alining openings in the yoke and leg, and cause the yoke, at its open end, to embrace the leg 7 and hingedly connect them together by passing, as the pin 10 is passed, a pivotbolt 1O through the yoke and leg, and applying a wing-nut 10 on the bolt. A bracerod 11 or spreader releasably connects the rear legs by means substantially similar to the means employed for connecting each leg 6 with a leg 7, and comprising a yoke 9 pinned to one leg 7 with an end-portion of the rod embraced by the open yoke-end or oke-j aws and pivoted thereto by a pin, the opposite end of the rod extending into a yoke 9 pinned fast to the other leg 7 and being releasably carrying a wing-nut, 10*, though a cotterpin may be substituted for this bolt and .nut.
A folding canopy 12 is provided, by pref erence, with the back-rest as an adjustable for sun-shading the user. I form the canopy with a rectangular oblong frame preferably of rods of adequate size, having the sides joined at their ends by sectional rods connected by hinges 13 at their meeting ends, the outer ends of these sectional rods being joined to those of the side-rods through the medium of yokes, like the yokes 9, pinned to the frame-sides and through it, and into- 10 passed through i whereby the refastened by a bolt at 10 i no embracing at their open ends and, there pinned to the rods of the frame-ends, as represented in 2. The frame is covered by a sheet 14- of canvas, or the like, secured as by stitching to the frame-rods and forming a valance 14. Posts 15, 15, which may be of the same diameter as the legs, and preferably formed like them, of wood or other light material, connect the canopy midway between its ends with the upper ends of the legs (3, to which yokes 10 are applied, and pinned, as hereinbefore explained, and eiiah are the lower cues of the posts, to which they are adjust-ably fastened by bolts 10 and wingnuts i"; and the posts are connected to the side-bars or the canopyframe by yokes 1O iilarly fastened.
The described construction renders my improved structure readily collapsible upon loosening the several wing-nuts to free the bolted end of the s reader l1, enable the legs 6 and I to be collapsed and folded together into a compact package and the canopy to be folded about it, thereby rendering the package convenient to carry to and from the place of use, where it may be readily erected and placed in the condition represented in 1. The substantially uniform means provided for connecting the parts releasably and pivotally together greatly facilitates the aforesaid operations,
the yokes l0 and their fastening means used for the purpose being not only durable and rendering the structure rigidly stable in its erected condition, but affording a uniform joining device for keeping in stock available to the manufacturer of the back-rest with the obvious advantages due to such uniformity.
I claim:
1. A back-rest having a pair of front legs connected by an interposed back-support of flexible material, a pair of rear legs pivotally and collapsibly connected at their upper-end portions with those of the rear legs, and a spreader releasably connecting the rear legs, characterized by the connecting means comprising yokes embracing and pinned to the front legs near their upper ends and embracing the rear legs near their upper ends, and pivot bolts passing through the yokes and rear legs and releasably fastened in place.
2. The back-rest according to preceding claim 1, characterized by the spreader having one end pivotally connected to one of the rear legs at the yoke thereon and its opposite end releasably connected with the yoke on the other rear leg by a bolt passingtherethrough and through the yoke and releasably fastened in place.
