ALUMINUM CHAIR CONSTRUCTION Filed June 30, 1958 2 Sheets-Sheet 2 INVENTOR. SOLOMON B. fiAOU/VS 57 57 5% 7 UV ATTORNEY United States Patent 3,035,866 ALUMINUM CHAIR CONSTRUCTION Solomon B. Raduns, 4910 17th Ave., Brooklyn, N.Y. Filed June 30, 1958, Ser. No. 777,165 Claims. (Cl. 297-454) The present invention relates to an aluminum chair construction and it particularly relates to a tubular aluminum chair construction.

It is among the objects of the present invention to pro vide a simple, durable aluminum chair construction which may be made of tubular parts with a matted or woven seat and back, and which will be comfortable for the user without causing any bars or part of the aluminum structure to bear upon the back or bottom of the user while sitting therein.

Another object is to provide a novel plastic handle to be mounted upon such chair which may be attached thereto and which will give a finished appearance to the chair without substantially increasing the cost thereof.

Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.

In accomplishing the above objects it has been found most satisfactory to form a chair of a continuous rectangular shaped tubing structure, then to form a back and a seat, with plastic webbing forming both the seat portion and the back portion.

A particular feature of the present invention resides in the fact that the angle or base of the chair has a U shaped extension member, the ends of which will be mounted in the sides but which will be removed within the line of the body so as not to project into the body and to permit the user of the chair to sit in comfortable position.

In the preferred form of the invention the U-shaped brace member which extends from side to side of the chair frame will have inturned end portions fitting into openings in the rear of the bends at the sides of the rectangular frame and will be held in position therein by the webbing. The side members may be made of a continuous tube having trapezoidal side arm rest members with vertical and rear cross members.

Another feature of the present invention resides in the fact that the arm rest carries plastic members which are mounted on the tubular members and have extensions upon which the forearms of the user may rest.

These arm rests not only add to the comfort of the user but also enhance the decorative appearance of the chair.

With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

FIG. 1 is a front perspective view showing the arm rest in position and the cross member between the back and seat elements, held in position by the webbing.

FIG. 2 is a side elevational view of the structure of FIG. 1.

FIG. 3 is a separated view showing the cross member ice and its manner of assembly to the rectangular seat and back member.

FIG. 4 is a fragmentary transverse sectional view showing the manner in which the end right angular legs of the cross member are inserted in the angle of the frame member.

FIG. 5 is a transverse vertical sectional view on the line 5-5 of FIG. 2, upon an enlarged scale as compared to FIG. 2.

FIG. 6 is a separated view showing the bottom of the handle structure and its method of connection to the side arm members of the chair.

Referring to FIGS. 1 to 4, there is shown a main rectangular frame A having a back portion B and a seat portion C and the transverse U-shaped reinforcing member D.

The back member B is provided with the open woven mesh or strapping E, while the seat member is provided with the strapping F. The leg structure is provided by the side trapezoidal members G which have the integral cross member H at the rear thereof and the forward U-shaped connecting member I.

The side trapezoidal arm members G are provided with the arm rests K which may be molded of plastic.

An important feature of the present invention is the U-shaped member D, which has an elongated base 10 with the transverse end legs 11. The transverse legs 11 fit into the openings 12 at the bends 13 between the back portion B and the seat portion C.

The legs 11, as shown in FIG. 4, will be fitted into the openings 12 at their ends 15 and will contact the inside face 16 of the bends 13.

The elongated portions 17 of the strapping or woven material E and F, extending from the upper cross mem-' her to the lower cross member 19, will pass over the mem ber 10 and hold it tightly in position, with the ends 15 of the legs 11 contacting the inside surfaces 16 at the bends 13.

Since the cross bar is substantially removed from the bend 13 and is to the rear of the bend, it will not press against the back or rear of the user of the chair and will make the chair much more comfortable than if the bar extended directly and transversely between the bends 13.

The side leg and arm rest members G, as shown in H68. 1 and 2, have the forwardly and downwardly inclined legs 35 with the substantially horizontal top portions 36 and the downwardly and rearwardly inclined tubular portions 37. The lower ends of the tubular portions 37 are connected by the cross member H.

The forward leg members 35 are connected by the U-shaped member I with the side legs 38 held in position by the rivets 39. It will be noted that the side members 35 are attached to the structure C by the bolts or rivets 49 and that the rear members 37 are attached to the side structure B by the bolts or rivets 41.

The arm rests K have the top flat portions 50, the downwardly extending fin 51 and the transverse reinforcing fins 52.

The fins 51 are held in position by the screws 53 fitted into the sides 54 of the tubular member G.

The top structure 50 has the upwardly extending pad member 55 with the extension 56 and with the bolts 57 extending through the tubular members 36 and screwed into the pads 55, as best shown in FIG. 5.

These bolts 57, as shown in the separated view of FIG. 6, extend through the openings 58 in the tubular member 36. Two of the pads 55 receive the threaded ends 59 of the bolts 57, while there are three other pads 60 which serve to fix the position of the arms K upon the tubular member G.

This plastic arm rest K is conveniently mounted upon the tubular member G and is held in position by the bolts 57 and the screws 53 and provides a comfortable position for the arms, as well as adding to the attractiveness of the chair.

As many changes could be made in the above aluminum chair construction, and many widely different embodiments of this invention could be made without departure from the scope of the claims, it is intended that all matter contained in the above description shall be interpreted as illustrative and not in a limiting sense.
