Patented Apr. 27, 1948 UNITED. STATES t PATENT OFFICE C Meyer Greiizer, Los Angeles, Calif. Application March 2l, 1945, Serial No. 583,906

My invention relates to chairs, particularly of the type covered by U. S. Letters Patent #2,306,878 issued to me December 29, 1942, and Patent #2,390,878 issued to me December 11, 1945.

The principal object of my present invention is, to generally improve upon and simplify theconstruction of the chairs Vcovered by my aforesaid patent and copending patent application, particularly the frames of the chair seat and the chair back and the means utilized for mounting the chair back on the chair frame.

Further objects of my invention are, to provide simple. practical and convenient means for mounting the seat upon the chair frame; to provide improved means for mounting the panels and upholstered parts of the chair back and seat upon their frames, and further, to provide a chair of the character referred to, which has no nail,

7 Claims. (Cl. 155-194) tack or screw heads exposed so as to scratch and mar the surfaces of walls, chairs and other articles of furniture with which they might contact.

Further objects of my invention are, to provide a 4chair which may be readily assembled or taken apart, also to provide a chair which combines simpli'city of construction with strength, rigidity and minimum weight and at the same time, presenting a. neat finished and pleasing appearance.

Further objects of my invention are, to provide a, chair of the character referred to which requires only a few screws or like fastening devices, few tools for assembly and disassembly and to provide a chair which may be readily knocked down so as to occupy little space whenstored or packed for transportation, thus affecting a substantial saving of storage and shipping charges.

With the foregoing and other objects in' view, my invention consists in certain novel features of construction and arrangement of parts which will be hereinafter more fully described and claimed and illustrated in the accompanying drawings, in which:

, Fig. 1 is a perspective chair.

Fig. 2 is an elevational view partly in section, of the chair back, l

Fig. 7 isa cross section similar to Fig. (i andV view 6i my improved showing 'a modification;

Fig. 8 is across section 'similar to FiguG and showing a further modied' construction.

Fig. 9 is a plan view of the chair .seat with parts broken away and in section.

Fig. 10 is an enlarged vertical section taken on the line Ill-I0 of- Fig. 9.

Fig. 11 is an enlarged detail section the Iline II-II of Fig. 9.

Fig. 12 is an enlarged detail section taken on a taken on `vertical plane, of the connection between the chair back and chair frame.

Referring by numerals to the accompanying drawings which illustrate a preferred embodiment of my invention, ldesignates generally, the chair frame which is formed from a single piece of metal tubing bent to form a horizontally disposed U-shaped base Il, a pair of vertically disposed front legs I2, horizontally disposed seat supporting rails I3 and upright back supporting members It.

The seat back comprises a rectangular frame preferably formed from a single piece of extruded cast, or molded metal or plastic materials, and comprising a strap-like` body portion I5 having on its inner face, a pair of spaced parallel ianges I6 and its outer face being ribbed or corrugated longitudinally, so as to produce a more or less pleasing and finished eiect.

Where formed from extruded metal, the ends of the member I5 may be brought together and welded as designated by X, Fig. 2 or said ends may be united by means of a joint member I i and screws or rivets I8, as illustrated in Figs. 3 ande.

The lower corners of the seat back frame are mounted on the upper ends of frame members le lby means of pins I9, which depend from the lower ends of blocks 20. of wood, plastics or the like, that are positioned between widened portions of the flanges I6, at the lower ends of the .upright side members of said frame and said blocks being secured to said flanges -by inails or screws 2l (see Figs. 5 and 12) Pins` I9 pass through apertures 22 in the lower corners of the seat back frame and enter `the upper portions oi' members I4 of the tubular frame l0 and when so positioned, the portions II, I2 and seat supporting members I 3 ofthe frame, are positively maintained in spaced relation and securely held against any lateral expansion or contraction.

A seat back rear panel 23 of sheet metal, wood or plastics is positioned in the rear portion of the seat back frame i against the rear one of the flanges I B and a `front panel "which :may be suitably upholstered, is positioned in the front Portion of said frame against thefront one of the anges I6. i

The panels may be secured to each other and to the frame, by means of screws 25 having their heads countersunkin backpanel 23 `asseeniu Fig.- 6, or such fastening means may take "the form of pins 26 passing through the panels with one pin carrying on its inner end. a socket 2l,

for the reception oi a stud on the end oi Ithe other pin, which arrangement functions after the manner of a conventional snap fastener (see Fig.7).

Where the chair back frame is formed from a strip of extruded metal or plastics bentto shape and its ends welded together, the strip may be formed with spaced grooves such as 2l (see Fig. 8) for the reception of the edges of the panels 2t and 24; such construction eliminating the iastening means such 'as the screws 25 and snap fasteners 26, '21.

The chair seat, seen in Figs. 9 to l2 inclusive, comprises a substantially rectangular frame 29, preferably formed in a single piece from extruded, cast, die cast or molded metal orplastics provided a short distance below its upper edge with an inwardly presented ange 30 and its outer face being ribbed or corrugated length- Wise to provide a. pleasing, nished effect.

Where this frame is formed fromr a piece of extruded metal, the ends may be brought together on the rear side of said frame and united by welding, or by means of a. joint member 3i and screws or rivets such as 32 (Fig. 11)

Formed integral with or secured to the side rails of the seat frame 29 by welding or otherwise, below'flanges 30 are inwardly and downwardly projecting projecting brackets 33 having curved under faces providing seats for the rails i3 of the seat frame and projecting outwardly from the lower ends of these brackets are short studs 34 which, when the seat is applied to the fra-me, enter apertures 35 in rails thus firmly securing the seat on said frame.

To position the seat on the frame, rails li are spaced apart a sufficient distance to enable studs to enter apertures 35 as said rails ex back to 4their normal positions and when the seat back is applied to the upper ends of members i9, the upper portion of the chair frame is securely held against lateral expansion or contraction so that the seat is firmly anchored on rails i5 of said frame.

A seat panel 36, preferably upholstered, is positioned in the seat frame 29, with its edges resting on flange 30 and the upper edge of said frame may be turned or extended slightly inward, as seen in Fig. 10, so as to overlie the edge of said panel and thereby retain same in the frame.

Where the seat frame and seat back frame are formed of metal, their exposed surfaces may be plated or polished so as to present an attractive and pleasing appearance.

If desired, a spring cushioned seat may be positioned in the seat frame.

Thus it will be seen that I have provided a chair which is simple in structure, inexpensive of manufacture, capable of being readily fabricated and which is very eiective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form and construction of the various parts of my improved chair may be made and:

substituted for those herein shown and described without departing from the spirit of the invention, the scope of which is set forth in the appended claims.
