CHAIR Filed May 23, 1936 Patented June 15, 1937 UNITED STATES PATENT OFFICE 2,08%,716 CHAIR Application May 23,

Claims.

This invention relates to improvements in chairs and it consists of the" matters hereinafter described and more particularly pointed out in the appended claims.

The present invention is more particularly concerned with that type of chair including a rigid base and a seat yieldably mounted thereon for a rocking-like action.

One of the objects of the present invention is to provide in a chair of the kind described, a novel mounting for the seat with respect to the base and which permits a gentle rocking action of the seat for the ease and comfort of the occupant.

Another object of the invention is to provide a chair of this kind that includes a base of tubing which though light in weight, is strong and rigid and at the same time, is attractive, modern and pleasing in appearance.

A further object of the invention is to provide a chair of this kind including a rigid base with a front portion and spring-like arms secured thereto and supporting the'seat whereby the same is capable of a gentle rocking action. I

Still a further object of the invention is to provide a chair of this kind having a relatively open, light-weight base made of top and bottom horizontal frames of tubing so connected together as to provide stability and at the same time permit the chair to be easily moved from one place of use to another and also permit cleaning under the chairwithout moving the same'from its location, when it is desired to do so.

The above mentioned'objects of the invention, as well as others, together with the advantages thereof, will more fully appear as I proceed with my specification.

In the drawing: 7

Fig. 1 is a perspective view of a chair embodying the preferred form of the invention with parts shown as broken away better to illustrate the construction thereof.

Fig. 2 is a transverse vertical detail sectional view through apart of the seat bottom of the chair as taken on the line 2-2 of Fig. 1.

Fig. 3 is a horizontal detail vertical sectional view through a part of the chair on an enlarged scale as taken on the line 3-3 of Fig. 1.

Referring now in detail to that embodiment 50 of the invention illustrated in the drawing, 5 indicates as a whole the base of the chair and 6 indicates the seat thereof.

In this instance, the base which is of an open character includes a top horizontal frame I and 55 a bottom horizontal frame 8 both preferably made 1936, Serial No; 81,527

of tubing. The top frame includes side member's B-9, connected together at the front by a cross bar or member Hi. Each side member has a turned down rear end portion providing a foot II. The bottom frame which is shorter from 7 front to rear than the top frame, includes side members I2--l2 connected together at the front by a cross bar or member l3. Each side member 12 has an upturned rear end portion 94 which is secured to a mid portion of an associated side member 9 of the top frame. As shown herein, the bottom frame is arranged in the vertical plane of the frontend portion of the top frame. Between the cross bars Ill and it of said frames are upright posts [5-4 5, the ends of which are secured to the respective front cross bars. These posts preferably are welded to the cross bars and the members I 4 of the bottom frame preferably are welded to the side members 9 of the top frame.

The corners connecting the side members and front cross bars together are each made on a generous curve and the corners connecting the parts II and M to their respective side members are also each made on a generous curve. The curves for all of said corners are preferably of about the same radius so as to present a uniformity of appearance to the base as whole.

The seat 6 of the chair which is of a depth from front to rear less than than that of the base as a whole, includes a suitable substantially rectangular frame It and a seat bottom IT. The seat bottom which may be made from a piece of sheet material such as veneer, carries upholstery. The frame is relatively deep and is suitably covered to give the desired depth to the seat proper. Associated with said seat, is a suitably upholstered back l8. Between the sides of the seat and the side margins of the back are curved arm rest members is which are secured at their ends to the seat and back respectively.

.'To yieldingly mount or support the seat with respect to the base, a pair of inverted substantially L-shaped flexible or pliable members 20- 20 are provided. Preferably these members which are spaced laterally to accord with the spacing between the posts 15, are made of flat spring bars. Each member 20 includes a vertical leg 2| and a horizontal leg 22 connected together by a rounded corner 23 of a generous curvature.

On the rear side of the cross bar I U of the top frame 1, in the plane of the posts I 5 are secured bracket clips or clevises 24. The vertical leg of each member passes down through its associated clip or clevis so as to be located behind its associated post and the bottom end of said vertical leg is secured to the cross bar l3 of the bottom frame in any suitable manner. As herein shown a rivet 25 is employed for that purpose.

Upon the underside of the seat bottom H which is preferably of a width less than that of the base 5 as a whole, are secured bracket clips or clevises Ell similar to those before referred to. The rear ends of the horizontal legs 22 of the members 29 are operatively secured therein as by meansof screws 21 as shown in Fig. 2. If desired these clips may be welded to the horizontal legs 22 of the members 20 secured by rivets or screws to the veneer seat bottom. By the use of these clips or clevises, the necessity of making holes in those parts of the members, upon which a flexing strain is imposed in the use of the chair, is avoided. Thus, as there is no area or place in said members where cracking under flexing strains can start, the said members have an indefinite period of usefulness.

It is to be noted that with the structure de scribed the seat is supported at or from the front of the base by means of the flexible members 28. Thus when the chair is occupied, the seat will flex about the rounded corners 23 and those parts of the vertical legs 2| of the members 29 above the clips or clevises 25.

The occupant may readily set up a gentle rocking action of the seat which is conducive to the ease and comfort of the occupant. It is also to be noted that the feet l l of the base engage the floor at a point to the rear of the seat 6 so that even though the rocking action set up by the occupant should become vigorous, the chair, as a whole, cannot tip over backward. The seat is of a width less than that of the base, and therefore, the rear end of the seat can swing down between the rear end of the frame in such vigorous rocking action.

The chair is not only comfortable, but is light in Weight as well as strong and rugged and presents an appearance pleasing to the eye.

While in describing my invention, I have referred in detail to the form, arrangement and construction of the parts of the chair, the same is to be considered only in the illustrative sense so that I do not wish to be limited thereto except as may be specifically set forth in the appended claims.

I claim as my invention:
