3 Claims.

chair and the chair in the row forwardly there-- of, permitting ready passage of persons before the seated occupant of such a chair; to provide such a chair whose seat may be upwardly tilted when not occupied; to provide such a chair whose supporting standards may be adjustably angularly spaced to provide for row curvature of a plurality of seats; to provide such a chair which is a modification of and an improved construction over the chair of my issued patent above identified; and, to provide such a chair which is attractive in appearance, comfortable in use and reasonably economical in manufacture.

An illustrative embodiment of the invention is shown in the accompanying drawings, wherein:

Figure 1 is a side elevational view of the chair whose relatively movable seat and back are shown as in their normally occupied positions;

Figure 2 is a View similar to that of Figure l but showing the relatively movable seat and back moved by the occupant to a position wherein others may conveniently pass before the occupant of such a chair;

Figure 3 is a View similar to that of Figures 1 and 2 but showing the seat in its upwardly tilted position when unoccupied;

Figure 4 is an enlarged sectional View on line 44 of Figure 1;

Figure 5 is an enlarged sectional View on line 5-5 of Figure 1;

Figure 6 is an enlarged sectional view on line B6 of Figure 1;

Figure 7 is a sectional view on line '|--l of Figure 6; and

Figure 8 is a sectional view on line 88 of Figure '7.

Referring then to the drawings wherein like parts of the structure shown are designated by the same numerals in the several views, a pair of spaced vertically disposed supporting standards Il! may be secured to the floor as by bolts, not shown, and the opposite sides of each supporting standard I0 is provided with a boss ll whose outer surface has a semi-spherical well i 2.

Seat supporting plates is, here shown as triangular in form and having an arcuate upper edge are each provided with a ball M at their base, one half of which ball is disposed in a well l2 of a boss I l of a supporting standard Ill and the other half of which is disposed in a semispherical well 15 of a clamp lfi'secured to a boss H by the bolt It, as best shown in Figures 4 and 5.

A seat supporting shaft I? is provided at each of its opposite ends with a bushing I 8 secured thereto by a rivet I 9 which bushings are each seated and secured within an aligned opening of a plate 26 disposed transversely of the shaft ll. An inverted U-shaped plate or saddle 2i sheaths and embraces the opposite sides of each plate 20 to which it is secured as by rivets 22, each bushing H? on the shaft I? being projected through an opening on the inner side surface of a saddle 2!, all as best shown in Figures 7 and 8.

Each plate 26 has a rearwardly depending por tion 23 forwardly of which the upper portion of a triangular seat supporting plate I3 is positioned between the opposite sides of a saddle 2 I, the bottom linear edge of each plate 26 riding on the arcuate upper edge of each triangular plate 53. As best shown in Figures '7 and 8, each triangular plate is provided with a V-shaped slot 24 through which a pin 25 projects and which pin is riveted to the opposite sides of the saddle 2| to limit the forward and rearward movement of the triangular seat supporting plate.

A seat supporting pan 26 supporting the seat cushion 2'! is pivotally supported on the shaft ll whose opposite ends project through bearing openings in the opposite side flanges of the pan 26 as best shown in Figures 6 and 8 and the back 28 which ispivotally supported at its opposite sides between the upper rear end of each supporting standard III as by pivot pins 29 is likewise pivotally connected at its opposite sides adjacent its base to the opposite side flanges of the seat supporting pan 26 adjacent the rear edge thereof by pivot pins 30'.

Since the seat supporting pan 26 is pivotally connected to the pivotally supported back 28, the occupant of the chair may effect a movement of the seat and back from its normally occupied position shown in Figure 1 to its position shown in Figure 2 in instances wherein the occupant of the chair desires to make more room for a person passing before him when he is occupying the seat, the pin 25 within each V-shaped slot 24 of each triangular seat supporting plate [3 limiting the forward and rearward movement of the relatively movable seat and back.

Since the seat supporting pan 26 is likewise pivotally supported on the shaft I1, the seat may be tilted upwardly to its position shown in Figure 3 when not occupied, the lowered or occupied position of the seat being fixed by the members 3|, each projecting from an opposite side flange of the pan 26 and each of which engages the under surface of a stop 32 projecting inwardly from the inner surface of a saddle 21 as best shown in Figure 6.

Because each supporting standard [0 is provided with a ball and socket connection with its triangular seat supporting plate I3, a row of chairs may be disposed in arcuate fashion as is conventional in theatres and the like and as is indicated by the dotted line disclosure in Figure 4.

It will thus be seen that the chair herein shown and described is attractive in appearance, comfortable in use and is reasonably economical in manufacture and while but one specific embodiment of the invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.

I claim:

1. A chair comprising a pair of spaced vertically disposed supporting standards, a triangular seat supporting plate swingably connected at its lower corner with the inner surface of each standard, said triangular plates each having an upper arcuate edge between their upper corners, a plate disposed above each triangular plate in plane alignment therewith having a linear bottom edge in engagement with the arcuate upper edge of its triangular plate on which it is adapted to rock, a shaft disposed and secured between the upper plates, a saddle embracing each upper plate to which it is secured and overhanging the opposite upper side portions of a triangular plate, said triangular plates each having a V-shaped notch through which a pin projects and which pin is secured between the opposite side walls of the saddle for limiting said rocking movement, a seat pivotally supported on said shaft, and a back pivotally supported between said standards and pivotally connected to the rear sides of the seat.

2. A chair comprising a pair of spaced vertically disposed supporting standards each having a semi-spherical well within its inner side surface, a pair of triangular seat supporting plates each having a ball at its lower corner seated within a well of a standard and each plate having an arcuate upper edge between its two upper corners, a clamp securing each plate to its adjacent standard having a semi-spherical well within which said ball is seated, a plate disposed above each triangular plate in plane alignment therewith having a linear bottom edge in engagement with the arcuate upper edge of its triangular plate on which it is adapted to rock, a shaft disposed and secured between the upper plates, a saddle embracing each upper plate to which it is secured and overhanging the opposite upper side portions of a triangular plate, said triangular plates each having a V-shaped notch through which a pin projects and which pin is secured between the opposite side walls of the saddle for limiting said rocking movement, a seat pivotally supported on said shaft, and a back pivotally supported between said standards and pivotally connected to the rear sides of the seat.

3. A chair comprising a pair of spaced vertically disposed supporting standards, a seat supporting plate swingably connected adjacent its lower end with the inner surface of each standard, said plates each having an arcuate upper edge, a plate disposed above each seat supporting plate in plane alignment therewith having a linear bottom edge in engagement with the arcuate upper edge of its seat supporting plate on which it is adapted to rock, a shaft disposed and secured between the upper plates, a saddle embracing each upper plate to which it is secured and overhanging the opposite upper side portions of a seat supporting plate, said seat supporting plates each having a V-shaped notch through which a pin projects and which pin is secured between the opposite side walls of the saddle for limiting said rocking movement, a seat pivotally supported on said shaft, and a back pivotally supported between said standards and pivotally connected to the rear sides of the seat.
