w. R. MCGOWEN v CHAIR Filed Jan. 5, 19 35 2 Sheets-Sheet 2 INVENTOR Patented at. 2, 1937 PATENT OFFICE cnAm. William R. McGowen, Pittsburgh, Pa., assignor to The McKay Company, Pittsburgh, Pa., a corporation of Pennsylvania Application January 5. 1935, Serial No. 564 2 Claims. 15MB) My invention relates to chairs and other seating structures, and is hereinafter described more particularly as in the class of metal furniture.
One object of my invention is to provide a seat frame of metal'havlng separately-formed spring elements incorporated therein.
Another object of my invention is to provide a seat frame mainly comprising tubular members 'in conjunction with spring elements interposed between and detachably connected to certain of said members.
Another object of my invention is to provide, an improved manner for connecting the ends of helically-turned springs to tubular frame memhers.
Still another object of my invention is to provide an improved form of connecting device be tween certain of the frame members of a seating structure.
Various forms whichmy invention may take are shown in the accompanying drawings wherein Figure 1 isa side elevational view of a chair; Fig. 2 is a front view thereof; Fig. 3 is a. sectional view, on an enlarged scale, of a portion of the 5 structure of Fig. 1; Fig. 4 is a view taken on the line IV-- IV of Fig. 1, on an enlarged scale; Fig. 5 is a modification of the structure of Fig. 3; Fig. 6 shows still another modification thereof; Fig. 7 is a front view of the structure of Fig. 6'; Fig. 8 is a 30 a view showing a modification of the structure of Fig. 1, and Fig. 9 is a face view thereof.
Referring first to Figs. 1 to 4, I show a chair having a framework comprising a. barpreferably of tubular metal and bentto loop form to pro- 'a5 vide seat frame portions l I, and back frame portions l2, the portions I2 having integrally-formed therewith a transverse portion l3 and a transverse portion ll integrally connecting the portions ll.
Side bars also preferably of tubular form are bent to form arm rests I! and less It, the rear ends of the arms II being detachably bolted to the back members l2. The seat members H are connected to the legs It by means of bracket members that are welded to the members H,
other types of cushions or seat strips can be employed instead of the cushions 2| and 24.
Llhe legs I6 are supported upon floor bars that are integrally connected at their rear ends by alooped portion 26, although the portion 26 may be dispensed with, if desired. Helically bent springs 21 which may suitably be formed of bar steel serve to connect the legs Hi to the floor bars 25. The ends of the coils 21 could have direct engagement with the tubular members l6 and 25, but in order to permit the making of said tubes of light gauge, and to avoid tearing or splitting the same by the springs, I incorporate bushings 28 and 29 in the floor bars 25 and the legs i6.
These bushings may have simply a press fit with the members l6 and 25. Reinforcing sleeves 3| and 32 are employed on the floor bars and the legs to further strengthen the joints at those points. l
In assembling the parts, the ends of the springs 21 may simply be pushed into the tubes l8 and 25, and will be frictionally held therein even during oscillation of the seat, since weight imposed upon the seat will tend to cause binding of the ends of the springs in the tubes. The springs, however, can be readily removed to facilitate handling and storage.
Another important advantage incident to my invention is that flexibility oryieldability of the seat structure is had without material bending of the tubular member in use, thus avoiding an tubes if they are made of sufflciently light gauge 7 material to produce a desired yieldability.
Referring now to Fig. 5,I show a structure wherein a tube 34, which may correspond to the tubes 25 and I6, is reinforced by upsetting the same somewhat'to thicken its wall as shown at SI, so as to prevent the end of the spring from splitting'the tube during flexing of the springs. The spring is releasably held in the tube 24 by indenting the tube at 38, into a depression or notchin the opening.
In Figs. 6 and '7, still another form of connection is shown. the tubes 31 and 38 forming the legs and floor bars, respectively, and corresponding to the tubes l6 and 25.- In this structure.
a collar or cap 39 is snugly secured over the end of each floor bar 38 and has an opening through its end into which the lower end of spring 40 is inserted. The spring is fastened therein by a pin 4!. The upper end of each spring is inserted into a collar 42 fastened by press-fit or welded to one of the legs 31, and the weight of the sitter will tend to hold the springs and the tubes 81 in assembled relation. Collars 39 and 42 with end openings of various sizes may be provided to fit springs of various thicknesses. The collars serve to reinforce the ends of the tubes, so that the tubes will not be split through flexing of the springs.
Referring now to Figs. 8 and 9, I show a structure wherein a bar or tube is bent to form a back frame 44 and seat bars 45, the seat bars 45 receiving the ends of springs 46 that may be formed similarly to the springs 21, and connected to the bars 45 in a manner similar to one of the connections shown in Figs. 1 to '7. Arm rests 41 are detachably bolted 'at 48 to the back bars 44 as are the bars lb in Fig. 1, except that the bars 41 are connected against the front faces of the bars 44 instead of to the sides thereof. The
forward ends of the arm rests 41 are bent and are connected by clips or clamps'49 to the springs 46. The clips 49 may suitably consist of plates bent to generally semi-circular form at their ends and held in clamping engagement with the members 46 and 41, by means of screws 50.
Leg portions 5| have connection with the springs 46, by joints of any suitable form, such as those heretofore described in connection with the springs 21, and are formed integrally with floor bars 52 that may be formed integrally with a rear portion 53.
In the structure of Figs. 8 and 9, as in the case of the other figures, the bending stresses are localized within the springs 46 and the parts may be readily assembled and disassembled.
I claim as my invention:-
1. Seat structure comprising fioor bars, members extending upwardly and rearwardly to form legs and arm rests, flexible spring elements connecting the legs to the floor bars, seat bars extending rearwardlyfrom the legs, a bracket member rigidly secured to each seat bar, each bracket member extending vertically at the inner side of a leg member and partially embracing said member, and means for connecting each bracket member to its associated leg.
2. Seat structure comprising floor bars, leg members of tubular form, spring members flexibly connecting the leg members at their lower ends to the front ends of the floor bars, a seat frame having side bars extending forwardly to the leg members, arcuate bracket members rigidly secured to the said side bars and extending parallel to and partially embracing the leg members, and a connecting element extending through each leg and one of the bracket members.
WILLIAM R. McGOWEN.
