, The object of the presentfinventionis to provide a simple, strong and durable jcon struction of folding chair, andtheinvention consists in the features of 'novelt'yherein described; illustrated in the accompanying drawings and particularly 'pointed out in of this specifijeation.
Figure 2 is a viewin side elevation showing the chair in partially folded orcollapsed position 7 t a "FigureB is'a back or rear view of the chair after it hasbeen completely folded.
' sectionon line 14ofFigure3,
Figure 5 is a"view,"uporian enlarged scale;
' through a portion" o'fthe chair seat,jthis' view being taken on line j5-5 of Figure '1. Figure 6 is aninyerted'plan yiew,'partially in section, ofone corner'of the chair seat. As shown, the/back members'and'front legs of ourimproved chaircornprise a U- l shapedframe l0,- preferably formedof a single piece of thin steeltubing, the ends of the front leg portions of-this frame 10 being fitted with suitable ferrules 11. Between the sides of the 'rfrarne lO and near its lt'op extends a braceplate 512. ,This plate-12 is preferably formed or thin-sheet metal with its top and bottom edges curled rearwardly I and'inwardlyasat 13 (seeFigure 4'); and
7 these inwardly curled orreinforced top and bottom edges, ofthe brace plate have'pro jections 14 that extend beyond the ends of the body portion of the plateand' enter holes that are formed in the walls of the sides of the U-shaped frame "10.1 When the plate 12' 4? has been placedin positionfbetween the sides of the u shaped frame 10,"with the projections 14 entering the holes in the sides of the' frame 10, the baseplate 12 will be held rigidly in place, asby spot Welding, as at 15, the reinforced ends of the plate 12 to:
i the sides of the frame '10.
If desired, the top: andbottoih iedges of the brace plate12'n1ay be further reinforced by wires 16, as shown at the lower portion 5o of the plate12 (seeldligure fl), infwhich case Figure is'a-yiew in yerticallan aud'imr W i inforcing platesj22 are riveted upon the inthe reinforced edgesl?) of the brace plate vpasses completely through the side bars of the frame 1Q and has its ends headed or upset .asat' 17. Upon this leg-pivot bar 17'is pivotally mounted? therear legs of the chair, spacing 1 ferrules 18 being interposed between such rear legs and the side bars of the frame 10. :As shown, the rear legs 20 are formedof metallic angle bars,={the outer flanges 121 of whichjareperforated to 'receive the pivot-rod 1'7, and,. preferably, re-
ner sides of these flanges 21 and are provided with holes through which the pivot rod 17 passes, The'fianged, "portion 23on each of the rear legsextends inwardly as shown,
and preferably the eXtreme-lower-ends of such flangefportions 23 r are bent angularly,
as at 24 (see Figure l) to afford abroader' bearing where such legs contact'fwith the floor or other surface on which the chair is placed. Between the lower "portions-ofthe rear legs 20fextends the brace bar 25 which is preferably an angle bar, one -me nber' of which is riveted asat 26 to theiinwardlyexten'ding'fianges 23fof the rearlegs.
Between the sidernembers of the franie lO extends" a seat-pivot bar] or rod 30 that serves topi'votally sustain the chair seat.
The ends of the" pivot rod pass-through thejinner walls'of the'side lhe'r'nbers of the frame 10and project-a sufiicient'distance within these tubular members to afford a secure support for'the seat. j Y The upper end of eachof the rear legs of the chairris"provided-With a supplemental plate: that is preferablyof angularflform,
eachsupplemental platehaying a flangeor member'35'that is riveted to the flange 23 of the corresponding rearflegand having a 1 fiange'or member 36 that projects at right angles to themember35 and-is perforatedtoreceivea bar-or rod 10, the endsof which project beyond thelflangef members 36 to enter guide grooves: beneath" the chair seat, as
passed through the flanges 36. The flange member 36 of each of the supplemental plates at the upper end of the rear legs is formed with a slot 43 adapted to admit the rod 40 when the chair is in folded position, as will presently more fully appear.
The seat 50 of our improved chair is formed of thin sheet metal stamped insuch manner that the edges of the seat depend and are turned inwardly, as at 51, thus affording great strength and rigidity to the seat and affording a broad edge therefor which cannot chafe or cut the garments of the user of the chair. As shown, the seat 50' is also formed. with a centrally depressed portion 52, adapted, if so desired, to receive a ad or cushion althou h when the chair 4 and 5.)
" is exposed to the weather this seat or cushion need not be employed.
. Beneath and along the side edges of the seat 50 extend the guides 55. (See Figures- These guides are preferably made as sheet metal channels spot welded in position beneaththe side .edge portion of the" seat; Each of the guides 55 is=formed with a long slot 56 and through these slots pro- .ject the eorrespon ding'ends ofthe rod 40 that extends between the upperportions of the rear legs 20.
One of the objectsof our invention is to insure'that the chair when in foldedposition shall occupy as little space as possible. For this reason, the leg-pivot rods 17 and the seat-pivot rod are arranged centrally with respect to the side members of the frame 10, and the flanged portions 21 of the rear legs 20 are arrangedwso that when the chair is folded, these flanged portions 21 will be between the side members of the frame IOga-nd the chair seat 50, which latter will overlapth e flanged members 23 of the rear legs 20. p V
\Vhen the chair is in extended position as illustrated in Figure 1, it affords an exceedingly firm and comfortable support for the user. hen the chair is to be folded or collapsed, it may be grasped by one hand at the top of the frame 10 and by the other hand at the front of the seat, and these parts will then be moved towards each other as indicatedin Figure2. .As the parts are thus shifted, the ends of the rod 40 will move along the slots 56 of thezguides until the parts are in the position -shown in Figure 4 of the drawings, at which time the seat and rear legs will be entirely between the side members of the frame 10, As the partsapproximate the completely folded position,
the rod 40' will pass into the slots 43, and
these slots 43 are so shaped or positioned with respect to the rod 40 that the walls of the slots will exert a frictional pressure upon the rod 40, tending to slightly deflect 'or for outdoor purposes, it is not desirable to provide it with a cushion but when used indoors or, in positions where it is protected fromthe weather, a cushion for the seat 50 may be employed. We have provided a cushion adapted to be detachably' connected to the chair, and this cushion ispreferably formed of a base plate of indurated fibre or the like,havin a fabric cover 61 folded around the base plate 60 and secured thereto, and padding 62 interposed between the base plate 60 and the cover 61. To enable the cushion to be readily connected to and disconnected from the-chair'seat, we prefer to employ the means next to be described: At each of its corners, the base plate 6Ov of the cushion is formed with a slot having a broadportion 64 and anarrow portion 65, the broad portion 64 being of sufiicient width to admit the head'66-of-the metallic fastener, the stem of which h'fastener is shownas formed of bendable members .67. The depressed portion of the chairseat 50 is preferably perforated for ventilation, and certain of the holes in the depressed-portion of the chairxseat are adapted to coincide with the stem of the fasteners 67 (when these stems are in extended position), when the fasteners have been moved into the narrow portions of the slots formed in the'base plate 60 of the cushion. When a cushion is I to be attached to the chair seat, the fasteners are first moved into the narrow portions 65 of the slots (see Figures 5 and 6). and the cushion is then placed within the depressed portion 52 of the chair seat, the extended stem portions67 of the fasteners being placed through the holes in the chair seat coinciding therewith. The. stems 67 of the fasteners arethen bent (as shown in Figure 5) so as to securely retain the cushion in position; for use. I I I While we have described whatweregard as the preferred embodiment of our invention, it will be understood that the precise details may be varied without departing" from the scope of the invention, and that features thereof may be used without its adoption as an entirety; V
