4 Claims. (01. 155-178) chair is durable, economicalto manufacture',;andf

which has an appeal to the critical eye? More: specifically it is an object of this inventionf-toprovide a chair seat having Iadouble "curvature therein comprising a pair of substantially'parallel arcuate rungs which have; secured to the; upper side thereof a plurality or transversely"ex.-';j, tending arcuate slats. 'I his' as Semb y,-; Oml S f the rungs and slats, is adapted t'ozbelplaced on the top rounds between the'jchair'posts;'-, :By pro-I viding arcuate rungs and arcuate slats,fthe-curvature of theseat extends in bothv directions and throughout the width and breadth'jthereof. In

I other words, the shape of the seat is substantially spherical at the central portion thereof.

It is a further object of this invention to provide a chair seat of the class described comprising a pair of arcuately disposed rungs having arcuately disposed slats secured thereto, said rungs having their ends fitting into the front and rear posts of the chair. This type of structure will replace the cane seat heretofore used and at the same time the arcuate rungs will replace conventional top rounds which have been used to hold the chair posts together.

Due to the high cost of hand labor for weaving cane seatsin this type of chair,. this seat fills a great need in enabling manufacturers to produce a low price chair to fill a demand whichcannot afford to pay present prices for cane seat chairs.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken injconnection with the accompanying drawings, in which- Figure 1 is an isometric view of a chair embodying a preferred form of the invention;

Figure 2 is a vertical sectional view taken along the line'2-2 of Figure 1;

Figure 11 is a vertical sectional view taken along the line ll-ll in Figure 8 showing the method of securing the ends of the rear arcuate rungs to the rear chair posts;

Figure 12 is avertical sectional view through the central portion of the chair seat and taken along the line lZ-I! in Figure 8.

Referring more specifically to the drawings, the numeral 10 denotes the front chair posts and V the numeral H denotes the rearchair posts, said' rear posts being adapted to extend upwardly at a greater distance than the front posts to form a means for supporting the chair back slat members H2. The front posts I0 are tied together by suitable rounds l4, whereas the lower portion ofthe rear posts II are secured together by suitable rounds IS. The front posts Ill and the rear posts H are secured to each other by suitable rounds [6. The structure thus far described is conventional in what is commonly known as a kitchen chair and it is upon this framework that my invention is adapted to be placed.

In order to provide an economical yet an attractive seat for this type of a chair, which also has the maximum comfort for the occupant a seat with a double curvature therein is provided. This seat comprises a front arcuate rung l8 and a rear arcuate rung I9, which rungs have disposed transversely thereof a plurality of arcuate slats 20 by any suitable means such as nails 2| 45 and 22. The slat members 20 are disposed in the central portion of the seat. Arcuate slats 23 are secured upon the edges or sides of the seat by any suitable means such as nails 24. These slats are very similar to the slats 20 previously described, except they are flared slightly at the front edge in order to cover up the top of the front chair posts Ill.

The front ends of the slats 20 are cut to form a slightly reverse curved portion 20a, and a similar reversed curved portion 26b is cut on the rear ends. The purpose of cutting the slats in this manner is to provide a comfortable contour of the seat as well as to provide a seat which has a pleasing external appearance. The slats 23 have similar reversed down-turned curved portions 23a integral with the front ends and the rear ends of these slats are cut as at 2311 to fit the rear chair posts Ii. to Figure 2 it is seen that the upper central portion of the slats and 23 are concave whereas the end portion of these slats are convex.

With the slats properly secured to the arcuate members I8 and It, the seat is ready to be installed in an ordinary kitchen chair. In order to do this, it is only necessary to place the seat upon the chair frame in the manner shown in Figure 2 after which suitable screws or

nails

26 and 26 are used to penetrate the uppermost rungs l4 and I5 and the ends of these screws or nails are adapted to be embedded in the central portion of the arcuate rungs l6 and I8.

It is thus seen that the seat of this type may be easily installed upon old chair frames by merely using a pair of attaching screws or nails such as designated by reference characters and 26. It will be noted, however that the ends of the arcuate rungs i8 and I9 are supported by the uppermost side rounds I6 which are disposed between the front and rear posts. Since the rear ends of side arcuate slats 23 have cut-away ends which encircle a part 'of the periphery of the chair posts I I, the seat will cover the entire top side of the chair, including the front posts It, front rungs l4, side rungs l6 and rear rungs l5.

Figures 7 to 12, inclusive, show a slightly modified form of the invention. In this form a chair frame is shown comprising front posts and rear posts 3I-. The rear posts are adapted to extend slightly above the seat level and have disposed between their upper ends suitable arcuate slat members 32 for supporting the back of the occupant. The lower ends of front posts 30 are secured to each other by means of suitable rounds 33 and the lower ends of the rear posts 3| are secured together by means of a round 34. The front posts and the rear posts are secured together by suitable side rounds 35. In order to provide a suitable seat for this type of chair, a front arcuate rung 36 is provided, which rung has rounded end portions 36a penetrating suitable bores near the top of front posts 30 A rear arcuate rung 31 is also provided which likewise has rounded end portions 31a for penetrating suitable holes in the rear posts 3|. Disposed transversely of these

arcuate rungs

36 and 31 are arcuate slats 38 by any suitable means such as

nails

39 and 40. These slats are slightly wider at their front ends than at their rear ends so as to allow the front side of the chair seat to be slightly wider than the rear side. Each of -the slats 38 has a front reverse curved portion 38a which turns downwardly immediately after passing over the front rung 36. Also the rear ends of the slats 38 have a reversed curved downturned portion 38b integral therewith which likewise turns slightly downwardly after passing over the rear arcuate rung 31. This assembly, comprising the

arcuate rungs

36 and 31 and the transversely disposed slats 38, forms a seat having a concave spherical surface in the central portion thereof with down-turned portions near By referring the front and the rear side so as to form a chair with a pleasing appearance and one that will provide, maximum comfort and not chafe the legs of the occupant. It should be noted that when this type of chair seat is used the front and rear top rounds on the ordinary kitchen chair may be dispensed with and have the

arcuatesupporting rungs

36 and 31 substituted therefor.

In the drawings and specification there has been set forth preferred embodiments of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
