D. T. ROBERTSON CHAIR Filed Jamil. 1926 2 Sheets-Sheet 2 Patented Feb. 28, 1928.



Application filed January 11, 1926. Serial No. 80,410.

The present invention relates to an im provement 1n chairs.

b. 1 is a perspective View of the chair; Fig. 2

is a sectional elevation showing the chair parts in set-up position; Fig. 3 is a rear elevation of the chair partially folded; Fig. 4: is an edge view of the same; Fig. 5 is a view showing the chair folded and enclosed in the seat; and Fig. 6 is an edge view of the same.

The illustrated embodiment of the invention is described as follows: The chair back consists of a top part 10 and a bottom part 11 hinged together. The side rails 12 and 13 of the top part of the back are united by two cross-braces, which are the top crossbrace 14 and the bottom cross-brace 15. The bottom part 11 of the chair back comprises two side members 16 and 17 which are also united by two cross-braces 18 and 19. The

hinges 20 and 21 unite the side rails 12 and 16, and the side rails 13 and 17, respectively.

A continuous canvas cover22 is provided for 25 the back, which is secured to the side rails, the top cross-member 1 1, and to the upper cross-member 18 of the lower partof the back by trunk nails. The hinge affords means for folding-the top and bottom por- 3o ducing the size of the chair to one con venient for portability.

\Vhen opened out, as shown in Fig. 1, the side rails are held in open position by two latches, one on each side of the chair. The latches are described as follows: The escutcheon 23 is secured to the lower end of the rear side of the side rail by screws 24. To this escutcheon 23 at its center is pivotally attached the latch member 25. A second escutcheon 26 is similarly secured to the rear sides of the upper ends of the side rails of the lower member of the back, and it is .provided with a button 27 adapted to receive the notch in the latch 25. After the chair is unfolded by swinging the latch 25 into position so that its notch engages the button 27 on each side of the chair, the. back will be held in a stiff, rigid, extended condition.

The lower member of the back is provided with a hinged supporting member indicated in a general way by the reference character 28. It has two side rails 29 and 30 united by a top cross-member 31 and a bottom crossmember 32. The top cross-member 31 is secured by hinges 33 and 3 1 to the top crosstions of the back upon each other for re-.

member 18 of the lower part of the chair back. It is therefore adapted to be swung out, as shown in Fig. 2. The lower ends of the side rails 16 and 17 of the lower part of the chair back, and the lower ends of the side members 29 and 30'of the hinged supporting member, are beveled, as shown at35, and covered with brass wear plates 36. These bevels are on the rear sides of the side rails referred to, and calculated to assist in supporting the chair member in the ground.

The lower end of the back canvas is bent back underneath the front and two cross seams are sewed through these layers, one about one-half inch from the lower end and the other parallel thereto and about an inch and a half above. The space between the two seamsreceives a piece of rubber tubing 15, .to form a cushioning stuffing to protect the back of the user from coming in contact with the cross-rail.

The seat of the chair consists of a canvas bag 37, which is provided with a flap 38 adapted by snap fasteners 39 to be secured to the surface of thebag in closed position. At the hinge of the flap to the bag the bag is provided with a strap 40 of canvas, which extends down thesides of the bag a certain distance, as shown in Fig. 5, up along the sides of thebag to the corners 41, and thence across the top of the bag and down the other side. Thisstrap is sewed fast to the bag. from its ends to the bag corners. From that point to the points 42 the strap is loose, and between the points 42 the strap is also loose, but at the points 42 the strap is sewed fast to the top of the bag. The loose portions 43 of the strap afford loops through which the legs 16 and 17 of the chair back may be thrust into the ground, and the loose portion 44 of the strap makes a handle by which thebag may be carried in the hand.

It will be seen from reference to Figs. 5 and 6 that the chair folds up into a small compass, and in such foldedcondition may he slipped into the bag and then forms a convenient package to be carried by the user to the beach or place where he desires to use the chair. He then opens the bag, takes the chair out, unfolds the back, fastens the clips in place, thrusts the chair back legs into the ground through the loops of the bag provided for that purpose, and then moves the strut into correct position with relation to the back and thrusts both the back legs and the strut legs into the ground a sufficient distance to afford a fair hold, and then the chair is suportcd in the position illustrated in Fig. 1 ready for use.

The cover performs the doublepurpose of a seat and a bag in which to carry the folded chair. rable.

Having thus described the invention, what is claimed is: s l

1. A chair comprising aback portioh having two side rail extensions for penetrating the ground, a hingedstru't member forming an oblique support for the back, and a seat member consisting of a chair bag and carrier adapted to receive the chair when folded having three loops upon its upper edge, two

outer loops to receive the side rail extensibns of the back, and a central loop serving as a handle for carrying the bag and folded chair. V s

2. A folding chair comprising an upper back portion and a lower back portion,

hinges uniting the upper and loiver back portions, clasps for holding the two back portions in open position, the two back portions having two side rails and two cross rails respectively uniting them, the side rails of the lower back portion being extended and forming feet to penetrate the ground, the lower cross rail of thelower back portion providing means for limiting the. distance which the feet of the side rails of the lower back portion may be thrust into the ground, the upper cross rail of the lower back portion being provided with ahinged strut member comprising two side railshaving foot extensions adapted to be thrust into the ground, and two cross rails, one located at the upper 'end of the strut member and the other located short of the lower end of the strut member, the lower cross rail of The chair is light, strong and duthe strut member acting to limit the distance which the feet of the strut member may be thrust into the ground, a canvas back coverthe entire upperback member and the upperpart of the lower back member, the chair being adapted to be folded by swinging the upper back member forward through 180 into contact with the front side of the lower back member, and the strut member being adapted to be folded forward toward the lower part of the lower back member so that the three hinged portions of the chair,

namely the upper back member, the lower back member and the hinged strut member all occupy positions parallel to each other of a length not exceeding the length of the lower back member side rails, {and a bag adapted to receive the chair in folded position, said baghaving a front and back and a hinged flap extending from the back over down on the front of the bag, the bag being provided with a strap secured to the edges near the open end of the bag, extending along both side edges of the bag to the top, and being secured thereto throughout such portion, and thence across the top of the bag, being secured thereto at two points DAVID '1.
