This invention relates tocomposite chairs, and relates more particularly to chairs madev of two or more members that may easily be assembled, and taken apart.

One of the principal objects of the invention isv to provide a chair that is light in Weight and rigidly constructed and, when taken apart, may be compactly stored and shipped. v

Another object is to provide such a chair that may be held together by screws without the same being visible from the outside. I

Another object is to provide such a chair that will have great stability. I, c

A further object is to provide such a chair which can be taken apart by the removal of a few screws. v g A further object is to provide such a chair that is made of aluminum tubing or the like; which combines rigidity with a degree of elasticity necessary for a comfortable seat. U a

Further objects and advantages of the invention will be set forth in part in the following specification and in part will be obvious therefrom without being specifically referred to, the

same being realized and attained as pointed out in the claims hereof.

Heretofore, chairs of metal tubing have been used, as well as composite chairs. The tubing chairs have mostly been made of an S shaped construction which provided a very resilient structure Without, however, giving great rigidity.

These chairs also have used up a large amount of space for storing and shipping.

Composite chairs as known to the prior art very often are complicated to assemble, and also may lacka rigidity as absbliitelyrequired for office chairs or the like. Furthermore, in many cases, these composite chairs do notprovide large "enough a base necessary for great stability; and an unstable chair does not only cause discomfort, but might involve accidents.

v The present invention intends to overcomesuch shortcomings and provides a composite chair made of metal tubing having a large base and stability, and due to its construction, combines rigidity with a certain degree of elasticity. When the chair is assembled it can take as'r'n'uch punishment as a non-composite chair, yet can be taken apart in afew seconds time. From the appearance of the assembled chair it c'annotbe discovered that it may easily be taken apart.

With the above andother'objects of the invention in View, the invention consists in the novel "construction, arrangement and combination of various devices, elements and parts, as set forth in the claims hereof, certain embodiments of the same being illustrated in the accompanying drawings and described in the specification.

in the accompanying drawings,

Fig. l is a perspective view of a composite chair incorporating my invention; Fig. 2 is a perspective view of a chair similar to the one shown in Fig. 1; c

3 is a sectional view of Fig. 1;

Fig; 5 is a cross section taken along line 55 of Figtfl and l lig. 6 is an elevational view showing the parts of several chairs taken apart, in man-omman' position for shipping.

In carrying the invention into effect in the embodiments which I have selected for illustration in the accompanying drawings and for description in this specification, I provide:

A. pair of substantially symmetrical side pieces I 5 and It, each thereof formed of a single piece of bent aluminum tubing or other suitable tubing material. The side piece H is shaped to provide an end portion forming a leg I 3, a substantially horizontal portion 16, and a back portion ES, to which correspond an end portion forming a leg 54, a horizontal portion ll which is substantially perpendicular to the leg I t, and a back portion [B -of theslde piece 42. Each portion of said side piece I2 is parallel to the corresponding portion of the side piece II.

A seat 21 made of wood, '01" textile, or other suitable rigid or pliable material is fastened to the horizontal portions 46 l? which. act as seat supports, by means of flat head steel screws 22 uwhich are countersunk into the material of said seat.

A back 23, made of wood oroth'er suitable rigid or :pliable material, is-secured near the upper end to the back portions t8 and H], of each of said vside pieces H and I2, by means of fiat head steel screws which arecoiintersunk into the material of said back 23.

A connecting piece 24, made of a single piece of bentaluminum tubing or other tubing material, is formed to 'providea pair of legs 25 and 27, respectively, "a pair of

parallel portions

28 and 29, perpendicular to the legs :26 and 21, respectively, and a connecting portion -31 between said parallel portions -28-and 29and integral therewith.

-Saidoonr-rectinglpiece or member =24-is detachabl'y securedto the underside of each of said side pieces *l and, L2, "as shown in Eig. 1, by fastening the outside of the intersecting L-shaped bend between the leg 26 and the parallel portion 28 of the member 24 to the underside of the horizontal portion l6 at a point thereof near the back portion ill of said side piece ll; similarly, the other parallel portion 29 is fastened to the underside of the horizontal portion I! of said side piece I2 by means of one of the countersunk screws 22 which at the same time secures the seat 2! to its place.

As shown in Fig. 4, the screw 22 reaches throng the seat 2| and the horizontal portion l'l into the parallel portion 29 which carries a thread for engaging said screw 22. The member 24 is so secured to the side pieces II and I2 that each

parallel portion

28 and 29, respectively, forms a small angle with the horizontal portions [6 and I! of said side pieces. Consequently, the legs 26. and 21 of said member 24 form the same small angle with a vertical line and, therefore, with the legs l3 and M of said side pieces II and I2. This position of the member with relation to the rest of the chair structure provides a large base for the chair, which assures great stability.

The connecting portion 3| of said connecting piece or member 24 is secured to the vertical legs I3 and 14 of said side pieces at the L-shaped bends intersecting said connecting portion 3| with the

parallel portions

28 and 29, respectively. As shown in Fig. 5, the L-shaped bend of the tubing has a hole 32 on the inner wall, suf iciently large to allow the head of a screw 33 to pass, and has a hole 34 coaxial therewith through which the screw 33 protrudes to engage a thread provided in the leg M. A similar manner of fastening is provided in connection with the leg [3 of the side piece II. The screws 33 are completely hidden from the outside, and at the same time, can easily be removed by inserting a screw driver through the holes 32 to loosen the screws 33.

The seat, which at its rear end is connected to the horizontal portions 16 and H by means of the screws 22 (see Fig. 4), is connected at its forward end to the same horizontal portions by means of additional fiat head screws.

Another modification of the present invention is shown in Fig. 2, in which the entire chair structure is provided by two

members

24 and 36, respectively. The lower member 24 is substantially like the one shown in Fig. 1. The upper member 36 has two

side pieces

31 and 38, conforming to the side pieces H and I2 of Fig. 1, which are, however, integrally connected to each other, thereby providing a back 39. A back cover made of wood or other material may be secured thereto if desired, but the same is not shown in the drawings, as the chair may be used without such cover. In all other respects, this modification has the same structure as the chair shown in Fig. 1 and described herein above.

The type of composite chairs described herein has a great rigidity, yet, especially when the seat 2! is made of pliable material, a certain degree of elasticity is provided. The seat 2| may be pliable as it performs no structural function. The connection between the side pieces of either type chair (Fig. 1 or Fig. 2) is provided by the connecting piece or member 24.

When the chair is taken apart, the pieces thereof may be laid man-n-man because the connecting piece 24 as well as the side pieces or the member 36, are rectangularly shaped. A considerable saving of space results when the structural parts are placed "man-on-man as shown in Fig. 6, which savingof space isparticularly useful and advantageous for storing and shipping.

I do not limit myself to the particular details of construction set forth in the foregoing specification and illustrated in the accompanying drawings, as the same refer to and set forth only certain embodiments of the invention and it is obvious that the same may be modified, within the scope of the appended claims, without departing from the spirit and scope of the invention.

Having thus described the invention, what I claim as new and desire to be secured by Letters Patent, is as follows:
