FOLDING CHAIR Application filed .Tune 19,

This invention relates to a folding chair, and relates more particularly to a folding chair having a can-opy readily foldable with the chair.

The principal object of the invention is the provision of a chair of the indicated character which will be of simple and inexpensive construction, one which may be readily set up for use and also be readily put in fol-ded condition so as to occupy but little space when not in use.

The nature of the invention and its distinguishing features and advantages will appear when the Jfollowing specification is read in connection with the accompanying ydrawing, in which- Figure 1 is a side view of a chair constructed in accordance with the invention.

Fig. 2 is a front view.

Fig. 3 is a side view of the chair folded.

Fig. 4 is a plan view of the seat. Fig. 5 is a view of the lower portion of the back.

Fig. 6 is a detail section.

Fig. 7 is a detail section taken on the line 7-7, of Fig. 2.

Referring now more particularly to the drawings, it will be apparent that the Vchair of the present invention includes a seat 10 which may be of any preferred construction,

but which will essentially be provided with slots or holes 11 occcurring therein near the rear edge thereof and also being notched at the opposite front corners thereof to provide shoulders or stops 12. Secured to the under side of the seat 10 at opposite sides of the seat in parallel relationship are legs 13. Legs 14 are pivotally connected respectively as at 15 with the legs 13 near the front ends thereof, and said legs 14 are respectively `engagea-ble with the shoulders or stops 12 to limit the pivotal movement of the legs 14 in one direction when the chair is set up for use.

The legs 14 are connected together by a cross- 15 bar and brace 16 at the lower ends thereof.

Each leg 14 has secured to the upper end thereof a piece 17. An arm 18 is hingedly connected as at 19 with each piece 17,V and the major portion of the arm projects rearwardly. A crossbar 20 has the opposite ends 1929. Serial No. 372,131.

`parts are arranged in chair forming relationship, as shown in Figs. 1 and 2.

In accordance with another feature of the invention the chair is provided with a canopy attachment. rfhe attachment includes a piece of canvas or other similar material 25. The rear edge of the piece of canvas 25 is fastened to the top piece 23 of the back by

strips

26 and 27 secured `to the top piece 23, by suitable fastening elements,pas shown most clearly in Fig. 6. The piece of canvas 25 is supported at the front by a metal frame of U-shape. rfhis frame therefore consists of side members 28 connected by a cross nie1n- 75 ber 29. The piece of canvas 25 is folded upon itself and is stitched to provide a hem or tunnel 3 which receives the cross member 29. The lower end 30 of-each side member 23 is bent at an angle with respect t-o the major portion of the member, and extends in a tapered hole 31 in the related arm `18, and also is threaded to receive a nut'32. Each end of the crossbar 20 is beveled as at 33 to enable the insertion of the end .30 of the re- 85 lated side member into the hole 31. It will now be apparent that the canopy frame will be associated with the arms 18 and cross bar 2O in sucha manner that the side members 28 will abut the beveled ends 33 while the 90 ends 30 will engage the arms 18, to maintain the piece of canvas 25 taut, when the parts are in the chair formingrelation. Fach of the side inembers28 of the frame has an offset 34inorderthatthefraniemaybebrought 95 to the proper folded position, and also' to obtain theproper distance between the cross member 29 `and the strip 26 when the chair is set up for use. Y

In order to set up the chair, one of the legs W0 Incidental to this last operation, the canopy,

frame will' be swung to a position in which the piece of canvas 25 will be stretched, due to the fact that the lower` ends of the side members 28 will abut the beveled ends 33 of the erossbar 20, while the ends 30 engage'the arms 18. The chair is then ready for use.

l/Vhen it is desired to collapse the chair, the

back 2l is lifted to disengage the lugs 24 from the holes 11, after which a forward 'push on the back 21 will cause pivotal movement of the front legs 14, and relative movement of the arms 18 with respect to the front legs 14 by reason of the hinges 19, and relative movement of the back 21 Vwith respect to the arms 18 by reason of the hinges 22 between the crossbar 2O and the back 21. In the co1- lapsed condition the partswill assume therelationship shown in Fig; 3.

It is to be understood that the canopy at-4 tachment' of the chair may be omitted, in which case, the chair will be manufactured havingy the other features set forth, withthe further understanding that the Construction of the'back may be altered and the size thereof reduced to be in proper proportion.
