.7 Claims.

This invention relates to improvements in chairs and it consists of the matters hereinafter described and more particularly pointed out in the appended claims.

One of the objects of the invention is to provide an improved chair more particularly adapted for outdoor use and which includes a metallic frame and a fabric or like covering providing the seat and back rest, the fabric and frame being so constructed as to permit a ready attachment and drawing taut of the covering into back restand seat providing relation with respect to the frame.

A further object of the invention is to so construct a chair of this kind, that the fabric covermg is supported as a rolled edge at the front end of the seat, to there avoid any substantially sharp corners.

Another object of the invention is to provide a chair of this kind having a spring base whereby the occupant may set up a teetering action in the chair and which 'chair also includes a forwardly extending leg or foot rest which may be swung into and releasably. secured in an out-of-the-way position, beneath the seat, when the use of such a foot rest is not desired by the occupant.

The above mentioned objects of the invention, as well as others, together with the many advantages thereof will more fully appear as I proceed with my specification.

I n general, my improved chair which is more particularly adapted for use outdoors as upon a porch, lawn or in a garden, includes a base having yieldable side members made of flat spring stock. Associated therewith is a tubing structure cured upon the yieldable side members of the A fabric covering is associated with said frames and is formed for a detachable connection at its ends with-said structure and at a point between its ends, said covering is so formed as to be operatively engaged by suitable devices, in turn connected to a fixed part of the frame, whereby said fabric may be drawn into a taut condition providing the-seat and back rest.

At the front of the seat frame is provided a transverse extending knee rail or roll of a sener ously curved cross section about which the fabric engages. This rail eliminates any sharp corners at the front of the seat and providesa wide. smooth surfaced support for the fabric so that it cannot draw into wrinkles at this point.

In connection with what may be called the chair proper and which comprises the base, seat and back rest, a foot or leg rest is provided. This rest is so pivoted at its rear end to the chair proper, that when it is so desired, said rest may be swung up under the seat and there detachably secured in an out-of-the-way position and without in any way interfering with the teetering action of the chair. Said foot or leg rest includes a frame of tubing and a detachable fabric or like covering which may be drawn into a taut condi-' tion during its attachment.

Referring now in detail to that embodiment of the invention, illustrated in the accompanying drawings:

1 indicates as a whole the base of the chair preferably made of flat strip, spring stock. As shown, said base includes upwardly bowed, floor engaging side members 2-2 which are connected together at their rear ends by a cross member 3. Each floor engaging member is bent upwardly at its front end as at 4 and then rearwardly to provide a portion 5 and to said portions a tubular framing is attached as will soon'appear. The portions 5- are preferably disposed in the plane of but above the associated floor engaging members of the base.

6 indicates as a whole a tubing, structure mounted on the base. This structure is formed to provide a back rest frame including substantially upright side members 7 ,and a seat frame including substantially horizontal side members the top ends of the side members 7 being connected together by a cross member 9. 0n the underside of said member 9, are provided laterally spaced, downwardly extending buttons or studs 912, best shown in Fig. 3.

Between each side member 8 of the seat frame and associated part 5 of the base is a brace or reinforcing member 10, the front end of which follows down the inclined front portion of said part, the members 8 and '10 and parts 5-all being connected together inoperative relation in nected together by a cross tube 13 while the posts 12 of both arm rests are connected together by a pair of vertically spaced top and bottom flat bars 14 and 15 respectively. These bars form a support for a front rail 16 of a curved cross sec-' tion to provide a rounded corner or roll at the front of the seat frame. The longitudinal top margin of the rail 16 engages upon and is preferably spot welded to the top surfaces of the bar 14 while the longitudinal bottom margin of said rail engages with and is preferably spot welded to the bottom surfaces of the bar 15. The top bar 14 is arranged in substantially the plane of the top of the seat frame side members '1 and on the bottom bar is provided a plurality of upstanding studs or buttons 17.

At the junction of each setof side members '1 and 8 of the back rest and seat frames, I provide rearwardly and 7 Slightly downwardly extending brackets 18 which are connected together by a cross rod 18. Also at said junctions there are provided downwardly extending, laterally flexible hooks 20, the purpose of which will appear later.

In connection with the seat and back rest frames, I provide means forming a seat and back rest, preferably of a good stout fabric. Sucha means is shown in Fig. 3 and the same comprises a strip 21 of fabric such as canvas, of a width approximating the distance between the sets of members '7 and 8 and of a length substantially equally the combined lengths of said members. Said strip is stitched transversely at a point between its ends as at 22 to provide a transverse pocket 23 on its rear side and which pocket divides the strip into a back rest portion 24 and a seat portion 25. In both sides of said pocket, are laterally spaced cut-outs, or notches 26, the purpose of which will soon appear.

The free-r bottom end of said seat portion of the strip as shown in Fig. is stitched'to there provide a transversely extending pocket 2'1 in which is located a flat metallic reinforcing bar 28, there being grommets 29 in said pocket and bar, spaced in accordance with the studs or buttons 17 of the bar 15 before mentioned.

The-top corner portions of said fabric strip are cutaway as at 30 to provide a narrower end or tab 31. This tab is stitched to form a transverse pocket 32 in which -is located a reinforcing metallic strip 33 and grommets 34 are provided therein and spaced laterally in accordance with the spacing of the buttons or studs 91: on the bar 9 of the framing 6. Stitched to the-rear side of the back rest portion of said fabric strip near said cut-out corners, are laterally extending straps or tapes 35. These straps or tapes carry on those ends stitched to the fabric strip and on their free ends respectively, coacting parts of snap fasteners 36..

The fabric strip 21 is applied to the framing 6, as follows:

The free end of the seat portion 25 is brought around the knee rail or roll 16 and the grommets 29 are engaged with the studs 1'! on the bar 15-.

In this operation, care is taken that the pocket 22 is disposed on the rear side of thestrip. The tab 31 is then brought upover the front of the cross member 9 and then around the same and its grommets 34 are engaged with the buttons or studs 9a on said cross member.

A rod 37 of substantially small diameter is then inserted into the pocket 23 from one end and straps 38 are looped around the bar 19 androd 37, the cut-outs 26 in said pocket allowing for the application of said straps. These straps which are provided with the usual buckles are pulled tight and this acts through the rod 3'7 to draw the seat portion 25 taut from its rear end and to draw down the back rest portion 24 from its bottom end so that the same becomes taut as best shown in Figs. 1 and 2. Thereafter the straps or tapes 35 are drawn-around the side members 77 and the coacting parts of the fasteners 36 are operatively engaged. With such an arrangement, it is apparent that should the seat portion 25 and back rest portion 24 of fabric stretch under use, this stretch can be taken up by further drawing up on the straps 38 so that said fabric is again made taut to better hold against saggin under the weight of the occupant.

In connection with the construction before deside frame members 3939 of tubing. Each side frame member includes an intermediate portion 40 which is normally inclined downwardly and forwardly from the knee rail or roll 16 and a rear end portion 41 which is inclined downwardly and rearwardly to extend under the knee rail or roll and there be pivotally connected as at 42 to the inner side of the bottom end of the post 12 of the arm rests. Each side frame member is further formed at the front end of the intermediate portion 40 with a leg 43 provided at its bottom end with a caster 44.

The side frame members are connected together by transverse members 45-46 and 47 respectively as best shown in Fig. 2, the former being a tube and the latter ones being flat bars.

On the rear side of the tube member 45 are lat One end of said strip is stitched to there provide a transverse pocket 50 in which is located a metallic reinforcing bar 51 having grommets 52 extending therethrough. These grommets are spaced apart a distance corresponding to the spacing of the studs or buttons 48 on the member 45 and with which they cooperate. The other end of. said strip is stitched to there provide a trans-.

verse pocket 53, with cut-out notches or recesses Inapplying the cover 49 to the foot rest frame, the grommets 52 are engaged with the studs 48 on the cross tube 45 of the foot rest frame and the covering is then brought around toward the top of said cross tube and over the cross bar 46. A rod of small diameter is then inserted into the pocket 53 from one end and straps 56 are inserted in therecesses 54 and passed around the rod 55 and cross bar 47 as best shown in Fig. 2. The straps which are provided with the usual buckles are then pulled tight and this will draw the covering 49 taut so that it is free from wrinkles after which the straps are buckled. Should the covering 49 sag in use, this sag may be removed by again tightening the straps.

Should it be desired to temporarily dispense with the foot rest, the chair is tilted backwardly about the cross bar 3 'of the base as wards and the foot rest frame is then swung about its pivots 42,into a position under the seat. In this movement of the foot rest frame, portions of the side bars 40 thereof, engage the spring hooks 20 and force them laterally outward until said side bars engage with a snap action with the shoulders of said hooks. This folded under position of the foot rest frame .is best shown in dotted lines in Fig. 2. When in this position, the foot rest is out of theway so that the chair ,may be more easily moved about from one place of use to another. When the foot rest frame is in this folded under condition it in no way interferes with the teeter- I ing action of the chair.

may be specifically set forth in the appended claims.
