grwmm WILLIAM R. BYRD RICHARD W. BYRD OBJECTS OF THE INVENTION It is an object of the invention to provide an improved method of making a chair.

Another object of the invention is to provide an improved chair.

With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims. it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

FIG. 1 is an isometric view of an integrally molded chair back according to the invention;

FIG. 2 is an exploded partial enlarged cross-sectional view ofa detail of the invention;

FIG. 3 is another view similar to FIG. 2;

FIG. 4 is a view similar to FIG. 3;

FIG. 5 and FIG. 6 show details of the embodiment of the invention shown in FIG. 3;

FIG. 7 and FIG. 8 are top and side views of the embodiment of FIGS. 5 and 6 respectively.

Now with more particular reference to the drawings, the chair back is indicated generally at 10, and the side pieces of the chair are indicated generally in phantom at 11. These chair pieces might be made of integral plastic material.

Cane back and cane reed weaves, and other types of woven materials are used for chairs, davenports, and other furniture components as inserts. A molded cane insert is made of a vinyl material or any flexible type plastic which can be molded in colors and which will be able to be stretched into position on a molded or wood frame and nailed into a final position.

The advantage in doing caning under this procedure is that the former way involved soaking real cane in water and installing by die-cutting and pressing into place. Real caning soaks the wood and the drying time holds up the finishing by many days.

The plastic cane is a one-piece construction, forming and eliminating three or more other operations. The cane is merely nailed by a nailing device into the frame.

Two types of plastic caning are used in this process: (I) a paintable; and (2) a color-simulated material which does not need painting, and the article is clean and has no paint to wear off.

A need was created by metal and wood manufacturers for a highly decorated chair back to simulate wood and to form in one integral piece which never had the possibilities to hold together by doweling, gluing, etc. Thus, applicant has created chair backs that were never possible to produce at an economical cost and giving added imagination to designers.

The method of fastening to the chairs was important in that plastic had to be engineered with a safety factor to eliminate breakage and the possibility of someone getting hurt, which wood does not guarantee.

Applicant has thus worked out a method to create safety by the addition of a nail or screw or rodlike object, integrally molded into place and thus adding strength and ease of assembly.

The nail type is used where the protrusion of plastic enters the metal tube on the inside or a drilled hole in a wood frame.

The size of nail or rod or screw is determined plication.

The chair shown has a back 10 supported on the sides 11. The back 10 may be molded from an integral piece of plastic material having the screws or dowels 12 at each side. These dowels may be in the form of the dowels shown at 112 in FIG. 2, 212 in FIG. 3. These dowels are inserted in the molded plastic material of the chair back 10. The dowel may have a head 13 on it to give it better bonding in the chair back and a molded protrusion 14 may either be integral with the back 10 or it could be as a separate piece supported on the dowel 12. The upper part of the back 11 has a bore 15 in it, which slidably receives the protrusion 14. The side member 11 may be made of metal, wood or plastic.

As an alternative, the back may be as shown at 110, with the dowel 212, which fits into a bore 215 in the protrusion 216, which in turn fits into the bore 217 in the side member 211.

The back has the integral molded plastic pieces made up of the top piece 18 and the bottom piece 19, that are integrally connected together by the intermediate diamond-shaped pieces 20. Thus, the

pieces

18, 19, and 20 are all integrally molded together by an injection molding process preferably.

In the embodiment of the invention shown in FIGS. 3, 4, 5, 6, 7, and 8, the caning material 310 is supported in the frame 311 and is inserted in the groove 312. The curved frame indicated in FIG. 7 and FIG. 8 receives the caning material and the caning material is in a weaved pattern which is stretched to give a taut look and feel in the curved frame. The vinyl or polyethylene imitation weave pattern is fixed to the border 316, which has a tongue thereon that is received in the groove 317 in the frame 311, which may be made of wood or plastic. The vinyl or polyethylene imitation weave material may be stapled or nailed at 321, as shown in FIG. 4, and the angle or wedge shape shown is received in the groove 317. The embodiment shown in FIG. 5 and FIG. 6 shows the weaved material at 410, having the tongue 416, while a similar material at 516 and 510 is shown in FIG. 6.

When the chair is assembled, an integral device is provided.

The foregoing specification sets forth the invention in its preferred practical forms, but it is understood that the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A chair made up of a seat, and a backrest,

said backrest being supported on laterally spaced vertically extending side pieces,

said side pieces terminating in ends having upwardly facing bores therein,

said backrest being made of an integral molded plastic piece,

said backrest having a top member and a bottom member spaced from each other,

means on said bottom member to attach the ends thereof to said side pieces,

said top member having a downwardly extending dowel member in each side thereof,

a protrusion molded on each said dowel and each said protrusion received in a said bore,

said dowel members and said protrusions each being received in one of said bores.
