PORTABLE FOLDING CHAIR.

Application filed August 30, 1927. lSerial No. 216,354.

rihis invention relates to portable folding chairs.

Its obj ect is to produce a chair of an attractive form in such manner that the invention can be manufactured in large quantities at a very low cost. My new chairs are adapted to be carried conveniently, when folded, for example, in motor cars for use at picnics, the chairs folding compactly and each being provided with ahandle so disposed as to keep the back and seat structures dependent from 'the handle and closed together, when carried. 'f he chairs are shown legless and may be used on the ground, on floors, benches vand on yachts, etc.

ln the accompanying drawings forming a part hereof and illustrating the invention,

Fig. l is a perspective view of a chair embodying my invention, in position of use.

Fig. 2 is a plan view of the chair in folded position, the view being illustrative of both the back and bottom of the chai in its folded position. l

Fig. 3 is an edge view of the chair in its l folded position.

Fig. 4 is an enlarged sectional detail at liner 4-4 of F ig. 2 and illustrates constructional features of both the seat and back of the chair. K A

ln the drawings, the illustrated chair seat includes a pair of bent wood rings l and 2. riheso rings are preferably of the same cross sectional dimensions and of the same interior and exterior diameters. Their meeting ends are shown opposed at?) and in the seat they are superposed one upon another and held together by screws or other fasteners 4 spaced apartaround'the rings at proper intervals.

Thesefrsteners serve not only to hold the two seat forming rings and 2 in superpos'ed rela- 'tion.s,'but also to prevent-the meeting ends of 'the rings from becoming displaced. The fasteners 4 serve to some extent in securing the chair bottom 5, which is preferably of flexible material, in place on the inward or upward surface of the ring 2. ln the construction shown, the ring l is the base ring of the chair seat resting on the floor, ground or other 'support when the chair is in'use and then holding the chair bottom 5 above the floor or ground. The bottom 5 is stretched tightly on theupper or inward surface of the ring 2 partially encircling` it and being` heldin place inr part bythe bent wood finishing stripsG applied to under side portions of the margin of the bottom. These strips are fastened in place at intervals by suitable fasteners 7 driver through the strip 6, the bent margin of the bottom 5 andl into the ring 2. rlhe meeting ends of the strips 6 are indicated by 8 and the fasteners 7 that hold the strips 6 in place against the curved margin of the chair bottom also serve to prevent the meeting ends of the strips G l The chair bottom 5 may be made of any suitable material fastened to the upper or inward surface of the ring 2, said surface being the upper surface when the chair is in use and the inward surface of the chair seat when the seat is in folded position. The bent wood .finishing strips S are preferably applied to the outer periphery of the base ring l, for neatness of construction and are held in place by fasteners 9.

The chair seat, comprised of a plurality of superposed bent wood rings and a chair bottom, the rings being screwed or nailed together, forms an economic structure as well as one of graceful contour.

Yi`he chair back includes a single bent wood ring l() of the same dimensions the chair seat rings l and 2. rlhese three rings l, 2 and l() may be rapidly and economically shaped and although they are shown of thel same dimensions, which may be varied, yet for standardization of manufacturing operations, it

is economical to make them as shown. -Themeeting. ends of the chair back ring 10 are indicated by il. Bent wood finishing strips .l2

are applied to the outer periphery and also to the-interior circumferential portion of the the front face of the chair back and the from becoming displaced.

upper face of the' chair bottom being then apportion of the intermediate bottom supporting vring 2, the fasteners 17 also p assing through the bent margin of thebottom and helping to hold it strongly in position of use. The other leaf 18 of the hinge is securedV to the back ring 12 at its upper peripheral portion by fasteners 19 that pass downwardly through the bent margin of the chair back into the bent body of the ring and assist in holding the chair back strongly to `thechair back supporting ring 1 0, rlhe hinged leaf 16 fastened to the, intermediate ring 2 is provided with a pair of spaced apart, upstanding bails 20 to which the ends of a looped handle V21, are secured. Thus, when thechair is in folded position and is cari riedby the handle, the chair back structure and the seat forming structure are conveniently carriedby the handle 21 rising from the mid Isection of theentiie structure, and

i -as the Vchair seat structure Vand back struc- CII ture are thenfdependent, the chair back and seat are readily carried in their folded position, which isalso a position convenientfor storage and transportation, when the chairs are to be crated or otherwise packed large quantities. The pintle 22 of the hinge is opposed to the meeting line of theopposable surfaces of the chair seat and back.

A pair of inwardly foldable, flexible straps 23 are used to limit the backward tilt of the unfolded chair, when itis to be used, there being' vone strap at one side and another strap at theother side of the collapsible seat and back.' Each portion 24 of each strap is bent overthe framework of the seat and back and secured to the seat or to the back, as the case may be, fasteners 25. The straps are inwardly foldable vat 26 betweenthe folded seat and back as shown in `Fig. 2. Thus when the chair vis in .folded position, the portions of they straps 2 3, between their ends,

' lie between the chair bottom andchair back andare out of theway while being carried aswell asin storage orv transportation. The straps areslightly yieldable in the lengthwise direction so that when the chair.

is in use, the slight givein thestraps makes f the. chair b ack more comfortable.
