FIG. 2.

INVENTOR. RAYMOND H. KING, BY Z Z I k z United States Patent CHAIR CONSTRUCTION Raymond H. King, P.0..Box 386, Hampton Bays, N.Y.

Filed July 15, 1959, Ser. No. 827,380 Claims. (Cl. 297-440) This invention relates to furniture, and more particularly, to chairs.

It is an object of the present invention to provide a chair of extremely simple construction, having a minimum number of parts, that can be effectively and quickly assembled for use.

Another object of the present invention is to provide a knock-down type chair having a minimum number of basically simple parts, all of which may be readily as sembled at the point of use, thus providing for more convenient packing, shipping, and assembly thereof.

Still an additional object of the present invention is to provide a knock-down type chair constructed from individual components that are readily assembled with each other to form an assembled chair without the use of additional fastening elements.

A more specific object of the present invention is to provide a chair having four basic components, all of which are readily assembled without the use of special tools, equipment, or skill, and which is extremely sturdy and of light weight construction so as to be capable of being made in large quantities at a relatively low cost.

All of the foregoing and still further objects and advantages of this invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing, wherein:

FIG. 1 is a perspective view of the chair made in accordance with the present invention, in fully assembled relationship.

FIG. 2 is a perspective view of a pair of frame members forming a part of the present invention.

FIG. 3 is a perspective view of a backrest member forming another part of the present invention.

FIG. 4 is a perspective view of a seat member forming still another part of the present invention.

Referring now to the drawing, a knockdown type chair made in accordance with the present invention, is shown to include a frame consisting of a pair of substantially identical frame members 12, each one of which includes a rear leg 14, a front leg 18, a cross bar 16 extending between the rear and

front legs

14, 18, and an upwardly projecting riser extension integral with the rear leg 14 and adjacent terminal portion of the cross bar 16. Each such frame member 12 may be conveniently manufactured by welding the free end of the cross bar 16 and angularly related front leg 18, formed as a single L-shaped member, to an intermediate portion of another straight section including the rear leg 14 and upwardly projecting extension 15. Such weld, or other fastening means 19 may be applied at the point of manufacture, thus providing two substantially identical frame members 12 that may be readily packed together.

A backrest is also provided in the form of a panel 20 having a pair of laterally spaced apart and upwardly converging bores 22 that open downwardly through the bottom surface 23. These bores 22 slidably receive the upper terminal portions of the upwardly projecting extensions 15 of the frame members, as the first step in the assembly operation.

The seat member of the chair is in the form of another panel 24 having a pair of laterally spaced apart, rearwardly converging and downwardly opening channels or grooves 26 in the lower surface thereof. Each of these grooves 26 is preferably of at least semicircular crosssectional configuration, of substantially the same diameter as the cross bars 16, so as to frictionally and detachably 3,003,817 Patented Oct. 10, 1961 2 receive andretain such cross bars 16 therewithin. If desired, additional securement means may be provided for preventing accidental disassembly of the seat panel 24 and the cross bars 16 of the frame members 12, should such bedesired. However, as soon as the seat panel 24 is'applied to the frame members, the backrest 20 automatically becomes locked in assembly with the upper" terminal portions-of the risers 15, because of the dovetail type connection therebetween furnished by the angularly related bores 22.

It will now be recognized that each of the component parts, frame members 12, seat panel 24, and backrest 20, may be conveniently manufactured of any desired material, color, and shape, at the point of manufacture. These parts may then be conveniently packed into a small carton or other shipping container and transported long distances without danger of scratching, damage, or the like. At the point of sale, or at the point of use, the parts may be readily assembled in the manner described without the need for additional fastening elements, tools, or skill, with utmost convenience. If desired, the chair may be used as a portable or travelling chair, so as to enable it to be carried from place to place in a knocked-down condition, and assembled at any desired point or location for actual use, following which it may be again returned to a knock-down condition for further transport purposes. When in the knock-down position, the chair may be readily carried in a car or boat. or the like and may be used for various purposes.

While this invention has been described with particular reference to the construction shown in the drawing, it is to be understood that such is not to be construed as imparting limitations upon the invention, which is best defined by the claims appended hereto.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A chair comprising, in combination, a backrest, a frame having portions slidably supporting said backrest, a seat, mounting means detachably supporting said seat upon said frame, and said seat carried upon said frame locking said backrest upon said frame against relative movement therewith, said frame comprising a pair of substantially identical frame members, each one of said frame members comprising a pair of legs, a cross bar extending between said legs, and an extension projecting upwardly from one of said legs, said backrest comprising a panel, and downwardly opening bores in one lower edge of said panel slidably receiving said upwardly projecting extension of said frame member, said bores converging upwardly toward each other to maintain said upwardly projecting extensions of said frame members in angularly related positions therewithin, and said seat comprising a rigid weight-supporting member, and said mounting means comprising a pair of rearwardly converging, downwardly opening channels extending along one lower side of said seat receiving said cross-bars of said frame members therewithin.

2. A chair as set forth in claim 1, wherein said channels are of at least semi-circular cross-sectional configuration, and said cross 'bars are of circular cross-sectional configuration of substantially the same diameter as said channels frictionally received within said channels.

3. A chair as set forth in claim 2, wherein said back rest panel is of rigid self-supporting construction.

4. A chair as set forth in claim 3, wherein said pair of legs and said cross bar of each said frame member lie in a common plane.

5. A chair as set forth in claim 4, wherein said frame members in assembled relationship with said back rest and said seat lie in angularly related converging planes.
