Specification of Letters Patent.

Patented May 13, 1913.

Application led November 15, 1912. Serial No. 731,478.

To all 'to/0m it may concer/a Be it known that I, JOHN B. Coon, a citi Zen of the United States, residing in Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Beach-Chairs, of which the following is a specification.

This invention comprises an improved beach chair of substantially inclosed charaeter for protecting the occupant from the glare of the sun or the chilling' effect of the wind.

The object of the invention is to provide a light, strong and comfortable chair of this description, which may readily be folded into compact condition and as easily opened for use.

The construction of the chair will now be briefly described, reference being had to the accompanying drawings in which- Figure l is a perspective View of the device; Fig. 2 is a front elevation thereof; Fig. 3 is a front elevation showing the chair folded; Fig. 4t is a vertical longitudinal section through the chair when open; Fig. 5 is a horizontal section through the same; and Fig. 6 is a horizontal section showing the chair folded.

The framework of the chair comprises two side frames 2, 2, and two back frames 3, 3. These frames comprise vertical uprights, the lower portions of which constitute legs, and connecting cross-pieces. The back members 3, 3 are hinged to each other as shown at t and also to the side members as shown at 5. The pintle of the hinge it is located on the inside so as to enable the back frames to fold toward each other when the chair is collapsed and the pintles of the hinges 5 are located on the outside so that the joints between the side and back meinbers open outward when the chair is collapsed. The back frames have stop or meeting portions, indicated at 6, and the side and back frames have other stop portions, indicated at 7. These abutting faces are cut at such angles that l the frames when opened are limited to positions in which the side frames 2 are parallel and the back frames 3 are in rearwardlyextending angular relation, as clearly shown in F ig. 5. The framework collapses into flat condition, as shown in Fig. 6, with the back fra-mes extending rearward from the side frames. Flexible4 straps 8 connect the adjoining uprights of the side and back fran'ies so as to prevent the side franles from swinging outward when. the chair is in folded condition. Side and back walls 9, 9 and 10, l0 of canvas or other suitable flexible material are secured to the side and back frames, and they may be formed by a continuous sheet secured at its ends to the front uprights of the side frames and extending around. and over the side frames and back frames.

A foldable top or roof ll of canvas or other flexible material is secured to the upper ends of the frames and when the latter are collapsed folds down between them as shown in Fig. The side walls 9 are provided at a suitable height with window openings 12 which atlord ventilation. A foldable flexible seat 13 of canvas or other suitable material connects the side frames, being secured at its ends to the cross bars 11i, and a flexible foldable back rest l5 connectsthe rear uprights of the said frames, beingl also preferably of canvas. A rigid foldable foot rest 16 is located between the lower front portions of the side frames and referably consists of a board hinged at 17 to one of the side frames and adapted to rest at its other end on a bracket 1S secured to the opposite side frame. The bracket 1S is provided with rigid upstanding pins 19, which are received in corresponding sockets Vin the foot rest when the latter is lowered into operative position. Vhen the chair is collapsed the foot rest folds up against the side frame, to which it is hinged as shown in, Fig. 3.

The seat and back rest l) and l5 constitute tension connections between the side frames and the foot rest 16 constitutes a thrust connection or brace. Additional braces are provided for holding the frames in open relation. As shown these comprise a toggle brace 2O connecting the rear uprights of the side frames below the seat 13, this toggle breaking upwardly when the chair is folded and a flexible triangular brace 21 interposed between the upper front portions of the side frames. This triangular brace comprises two bars 22, which are pivotally connected with the side frames and llexibly connected with each other as by means of a stud and slot 23, and a knockdown brace bar 24k pivoted at one end to one of the bars 22 and at the other end being constructed to hook over a stud 25 on the other bar 22. The bars 22are of such length that when the frames are opened to the limiting positions determined by the stops 6 and 7 the said bars are adapted to occupy inclined positions as shown in Fig. 2. When the chair is collapsed they swing downward between the side frames or the projections thereof as shown in Fig. 3. By raising the bars 22 until they are inclined upward the top 11 is forced upward in the middle so as to assume a pitch toward both sides for the urpose of shedding water. rIhe bars 22 are held in this relation, against the tension of the top 11 by means of the brace bar 24. The top 11 has a short downward-extending hood portion 26 at the front which covers the brace 21 and holds it beneath the top.

When the chair is open and in use it is perfectly firm and steady. The toggle brace 2O connected to the side frames adjacent their hinge portions forcibly expands the frames so as to hold the stops at 7, 7 and also at 6 rigidly against each other. Thus the toggle brace cooperates with these stops to lock the frames open ina firm and braced condition. The seat 13 and back 15 preferably contribute by acting as tension members. The foot rest 16 and the structure 21 constitute additional braces at the front. When a person sits on the seat and leans against the back rest, the latter tends to draw the frames together, but the several braces effectually oppo-se such tendency. pocket 27 secured to one of the back walls constitutes convenient means for holding various objects.

Copies of thispatent may be obtained for five cents each, by addressing the `What is claimed as new is:

1. A collapsible beach chair comprising two side frames, two back frames' hinged to each other and to the side frames, said frames folding together in flat condition with the back frames extending rearward from the side frames and when open being` limited to positions in which the side frames are parallel and the back frames in rearward-projecting angular relation, canvas walls and a foldable canvas top secured to said frames, foldable braces or thrust members between the side frames to hold the frames open, and a canvas seat and a canvas back rest connecting said side frames and constituting tension members coperating with said braces or thrust members to render the chair firm in its open condition.

2. A collapsible canvas structure comprising two side frames, two back frames hinged to each other and to the side frames, said frames folding together in fiat condition, canvas walls and a foldable canvas top secured to said frames, and a fold able triangular brace at the upper ends of the side frames, said brace comprising bars pivoted to the respective side frames and flexibly connected with each other and adapted to fo-rce the top upward in the middle so as to give it a pitch toward both sides, and a knockdown brace bar for holding the aforesaid bars in such position against the tension of the top. v

In wit-ness whereof, I have hereunto set my hand this 30 day of October, 1912.
