. 2 Claims.- (011555-116) This invention relates to chairs, particularly to self adjusting chairs of the type commonly used on steamers, beaches, lawns, etc.,

An object of the present invention is to provide an improved chair of the above type which is easily adjustable to various reclining positions and is capable of being folded into a very compact condition when not in use or for transportation.

Another object of the invention is toprovide an improved chair of the character mentioned, which is simple in construction, and reliable and exact in function under all conditions of service.

The invention also comprises certain new and useful improvements in the construction, a1"- rangement and combination of the several parts of which it is composed, as will be hereinafter more fully described and claimed.

In the accompanying drawings:-

' Figure l is a perspective of the frame of a chair constructed according to myinvention, the fabric portion of the back and seat being omitted so as to show clearly the underlying structure;

Fig. 2 is an elevation looking at the rear ,of

the chair;

Fig. 3 is a vertical longitudinal section taken on the line 3-3 of Fig. 2; a

Fig. 4 is an enlarged elevation of a portion of the chair frame showing the manner in which the back and seat frame is adjustably mounted there-- on, the seat and back frame being shownin one position by full lines and in two other positions by broken lines; and

Fig. 5 is a rear elevation of a portion of the structure shown in Fig. 4, showing the manner of pivotally connecting the back frame to the adjacent portion of the chair frame.

Referring to the drawings, the chair comprises front legs II, positioned parallel. to each other the bottom and mid points, respectively. As is customary, the rods I2 and I3 are rigidly fixed Near their bottom, the rear legs I4 are connected by a rod l6, which is rigidly fixed in any suitable manner to the rear legs I4.

Also pivoted to the pins I5, are the front ends 55 of arm rests I'I. These arm rests extend rearand connected by parallel rods I2 and I3 near' A pair of rear legs I4 are pivoted, by bolts or wardly, and, as is customary, lie in a substantially horizontalplane'when the chair is set up.

The rear ends of the arm rests I! are supported from the rear legs I4 by brace members I8. The upper ends of the braces l8 are pivotally. 5 connected to the rear ends of the arm rests ll by bolts or pins I9, and the lower ends of the braces are'connected by a rod 20.

shown in Fig. 2, the rod 20 is mounted in openings 2! formed through the braces l8, and 10 the ends of the rod 20 project a suitable distance beyond the braces I8,*as indicated at 22. g The rod 20 is rigidly fixed to the braces in any suitable manner, such as by nails 23.

Formed in' each of the rear legs I4, at a suitable distance above the rod I6, is a notch 24. The projecting ends 22 of rod 20 are. adapted to seat inthe notches 24Yto retain the frame of the chair in position as shown; 7

' At a suitable distanceabo-ve the rod 20, a sec: 4 0nd rod 25connects the braces l8, being rigidly fixed to said braces in any suitable manner. The rods 20 and 25 are disposed substantially parallel, however, rod '25 does not project beyond the braces I8.

Mounted on rods l3 and 25, and disposed adjacent tothe'legs II and I4, are seat supporting members in the form of bars 25.

The bars 26 are positioned adjacent the inner surface of the legs I I, and the brace members 18 3 are interposed between the outer surface of the bars 26 and the inner surface of the rear legs IA. The arm rests l'l'are positioned against the outside surfaces of the rear legs I4 and brace membersI8'. This arrangement permits the framework to befolded when the rod 20 is lifted out of thenotcheszl, I

The-seat comprises a frame composed of side rails 21 which are connected at thefrontby a r0d'28, andconnected at the rear by a rod 29. 4c

The seat supporting bars 26 are arranged substantially parallel and the siclerails 27 of the seat are also parallel and are superposed on the bars 26' was to be wholly supported thereby, as shown in Figs. 1,; 3, and 4. The side rails 27 are slidably mounted onthe' supporting bars 26for forward and backward movement, and in its forward and backward movement the relative position of the seat with respect to the frame of the V chair and especially the supporting bars 26 never changes. That is to say, since the seat frame rests on and is supported wholly by the bars 26, and said bars 26 are stationarilyheld in the chair frame when the chair is set-up, the side rails 21 of the seat frame will always remain in a subconnected, at a point adjacent their upper ends,

by a rod 3!. v

The back is supported from the arm rests H;

by means of link devices 32, so constructed as t plurality of to permit tilting of the back in 2. positions.

As shown best in Figs. 4 and 5, each linkdeyice 32 comprises an elongated member-, preferably formed from metal, and having an offset and laterally projecting upper end portion 33, which is formed with a perforation by which the link is mounted on pivot pin 19.,

A slot 34 is formed in the main body portion of link 32 in which is disposed a pin 31fcarried by each side member 30 of the back. fInlieu of pin 31 any other equivalent member or device may be employed for connecting the side member 30 to link 32.

The upper end of slot 34 is formed with a notch 35 which extends outwardly with respect to the slot. Intermediate of the slot 34, there is another notch 36 which also extends outwardly.

As shown in Figs. 1 and 4, when the back is in a slightly inclined position, the link devices 32 project outwardly from pivot pins I 9 and notches 35 and 36 are disposed on the upper edge or upper side of the slots 34, in position to receive pin 31. When the back is lowered to a more reclined position, pin 37 will be disposed inthelower ends 38 of slots 34. position in the notches, due to the downward pressure exerted by the weight of the links 32, it being understood that said links 'are loosely pivoted on the pins l Qand normally tend to hang vertically downward from the pins l9.

The chair may be quickly folded into a fairly compact bundle for transportation or storage" by simply lifting rod 20 out of the notches 24 andforcing the legs together. The particular construction described above, due to the arrangement of the various parts, takes up a comparatively small floor space when'set up or when folded.

As shown in Fig. 4, repositioning of the back as above described, effects a simultaneoeus sliding movement of the seat frame upon'supporting' bars 26, and in sliding forwardly and backwardly on the bars 25, the side rails 2'. f the seat frame will, at all times, rest upon the bars 26, irrespective of the position of the back frame of the chair.

This is due to the loose pivotal connection of the back with the arm rests l1, provided by link devices 32 and their associated parts.

As shown in Fig. 3, extending from front seat rod 28 to upper back rod (i l and fastened to said rods and also to rod 25, is a' strip of suitable fabric, such as canvas, duck, orthe like. This The pins 3? will be retained in canvas provides a seat 40 and a back support 4 for an occupant of the chair. I

The glide of the seat is limited by means of a. loop member 42, fastened to front seat rod 28 and looped around rod l3, as shown in Fig. 3. Loop member 42 may be formed from any suitable flexible material or fabric, such as canvas, duck, and the like.

The relative positions of the seat and back of the chair may be quickly shifted by simply lifting the link devices 32 so as to move the pins 31 out of the notches in said link devices in which they are disposed and repositioning the pins .31 in other notches of the link devices 32. Fig. 4 illustrates several positions in which the back can be set by shifting the links 32, as above described, and such movement of the back effects a corresponding shifting of the seat on its supporting bars 26.

Changes may be made in the details of construction and in the arrangement of the parts above described within certain limits without departing from the. spirit of the invention.

Having thus described my invention, what I claim is:-

l. A chair of the type described comprising pivotally connected front and rear legs, arm rests also connected to said leg pivots, brace members pivotally connected to said arm rests and detachably connected to the rear legs near the lower ends thereof, substantially horizontally disposed seat supporting bars connected to said front legs and to said ,brace members, pivotally connected back and seat frames of which the latter restswholly on said seat supporting bars, said seat frame being adapted to slide forwardly and backwardly on its supporting bars without any part separating therefrom, links pivotally connected to the arm rests, pins projecting from the back frame, slots formed in said links, and notches formed in said slots for receiving said pins for retaining the backframe in a'plurality of positions. f

2. A chair of the type described comprising pivotally connected front and rear legs, arm rests also connected to said leg pivots, brace members pivotally connected to said arm rests and detachably connected to the rear legs, substantially horizontally disposed seat supporting bars connected at their rear end to said brace members, a tiered connecting the front legs for supporting the forward ends of said seat supporting bars, pivotally connected back and seat frames of which the latter is slidably mounted on said supporting bars whereby said seat'frame is disposed in a substantially fixed horizontal position at all times, links pivotally connected to the arm rests, pins projecting from the back frame, slots formed in said links. and having means therein for receiving saidback frame pins for retaining the back frame in a plurality of positions, and a loop memberncarried by the seat frame andlooped around said tie rod for limiting the movement of the seat frame on its supporting bars.
