To allwhjom it-may concern;
Be it known that we, Joan H. Bun, and Earn. T.
United'States, residing at Sleepy Eye, 1n the countyof- Brown and State of M nna: sota, have invented certain new and useful Improvements in Folding Chairsfor Qamping or Boating, of which the vfollowmg'rs' a specification.
19 The present invention relatesto a portable chair suitable for camping orboatingr parties. v
The main object of the invention is to rovide a chair of this 'class'that can be fo ded to takeup very' little room, and constructed light enough to be carried comfortably 1n one hand.
Another object of the invention is to furnish a cover forthe chair, which is attached to the back thereof when the chair is erected for use, and which cover constitutes a receptacle or bag for carrying the chair during transportation.. 4
In the accompanying drawings, one embogiment of .the invention is illustrated; an
Figure 1 represents a front end elevation of the chair erected; Figure 2 is a side elevation thereof;
Fi re 3 shows the chair partly folded and eposited on top of a boat seat;
Figure 4 is a perspective view of the cover formed as .a bag and containing the'folded chair ready for transportation;
Figure 5 is a plan view of the cover unfolded;
V Figure 6 shows a fragmentary side elevation of the. chair with a modified form. of brace for the back thereof.
Figure 8 a perspective view ing plate for theback brace. In the drawings, reference vnumeral 10 lar metallic strip 12 is furnished along the rear ed e of the seat.
On t e top of the seat and at the rear end thereof is provided a pair of double hinges 13. Each hinge has a horizontal foot WINKELMAN, citizens of 4 the Figure 7 is aperspective view of a of a reinforcrepresents the seat of the chair, which is 14 restin on top of the seat andianother f hori zonta foot '15 engaging on the under .side of the seat and hel firmly thereto by asingle. bolt orrivet 21. Each-hinge has an upwardly directed loop 16 adapted to engage a transversely running'bar' 17 of the back rest, which has two uprights 18 extending to asuflicient height from the transverse bar 17 to make a comfortable ,rest. The
hinge has also a downwardly directed loo 19 or the rear legs 20. It will thus be ev1- dent that only two hinges, one'fat each end of the seat are necessary to accommodate both the back rest 17 18 and the rear le 20, andthat these hinges are retained m position firmly by a single bolt or rivet 21. The back rest as well as the front legs 22 and the rear legs 20 are preferably made of metallic tubing'of sufficiently large diameter to'combine st ength with lightness for'the purposerequired. 4
. At an approximately 45 angle, a folding brace 23 is hinged as at 24 to each upright 18 of the back rest and at its lower end as at 25 to the side of the seat 10. This brace has the usualhinge 26 at approximately the middle thereof permitting the foldin of the brace in one direction only; A rein orcing plate 27 of rectangular contour and having a width corresponding to the thickness ofthe seat 10 is slit transversely as at 28, and the two narrow flaps 29 thus formed, 1 are-bent perpendicularlyin the same direction "against the body of the plate. This reinforcing plate is driven with its flaps 29 into the wood of theseat 10 in a position to receive the hinge pin 25 in the aperture-30 provided therefor. In this manner a very strong hinge joint is produced at each side of the seat 10 requiring no rivets or screws for retaining it in position.
Instead of thebrace 23 being made from a flat metallic band, a chain 31, as seen in Figure 6, may be used. I
The front le as has already een described, are made of metallic tubing, and while the rear legs 20 are carried in the same hinges 13 .as furnished for the back rest, the front legs 22 have individual hinges 33 carried on the under side of the seat-10 and secured by means of screws or rivets entering through the reinforcing plate 11. Both the front and.
rear legs terminate at the hinges with ina wardly turned ends 34, which are slightly 22 and the m legs 20, 1 0
bent to insure that the ends will not slip out of the hinges. The front and rear legs are'each cross connected as at 35 at the bottom end, and
at each corner is formed a foot 36 upon which the legs are standing, the cross connections 35 being slightly raised above the ground. is preferably less than the width across the rear legs 20, so as to permit the latter to fold outside of the former and lie flat against the under side of the seat 10.
Bracing rods 37 and 38 are furnished for the front and rear legs and hinged to the same as at 39 and 40 respectively. When in folded position, these braces are laid along the front and rear legs, after having been swung in downward direction therefrom. These bracing rods run substantially in diagonal direction inwardly from their,
hinge points on the legs, each rod being formed by a singlewire having a straight narrow portion 46 at the middle thereof adapted to engage in a notch 41 provided at each end of a block 42 secured on the under side of the seat. A retaining pad 43 holds a latch spring 44 against the under side of the block 42 and all three parts are secured together by means of screws or nails 45 to the seat, as best seen in Figure 3. The spring 44 extends to front and rear of the biock 42 in such a manner that its ends cover the notches 41 and are adapted to retain the middle portion 46 of the brace rods 37 and 38 in the notches 41 when the chair is in erected position. To release the bracing rods from these notches, it is necessary to bend the ends of the spring 44 downwards, when the middle portions 46 of the rods will slip out of the notches, so that the rods may v thereupon be swung down along the front and rear legs 22 and 20, as seen in Figure 3.
The cover 47is preferably made of canvas or other fabric that may be waterproofed, and is of a width slightly greater than the width of the seat, and a length somewhat greater than twice the length of the seat. To the upper half of the cover is sewn a pocket 48, see Figure 5, which has a width corresponding to that of the back 17, 18 of the chair. With the chair in erected position, the pocket 48 is slipped over the uprights 18, as seen in Figures 1, 2 and 3, while the rest of the cover hangs loosely down the rear side of the back rest.
A handle 49 is furnished at each end of the cover and along-its side edges are provided snappers 50,-by means of which a receptacle or bag is produced when the two ends of the cover are folded together with The width across the front legs 22 when camping, .but in Figure 3, with the legs 20 and 22 folded under the seat 10, while the back 17, 18 is still erected, the chair is suitable to be placed on top of a seat in a canoe or boat, as indicated in this figure.
