Application June 25, 1948, Serial No. 35,230

4Claims. (01.155-195) The present invention relatesto chair structures and more particularly to supporting pedestals for chairs of the type installed in motorbusses or other vehicles.

The primary object of the invention is to provide a unitary sheet-metal pedestal for supporting the frame of a chair structure in which the chair seat and chair back are mounted on said frame.

This and any other and more specific objects hereinafter appearing are attained by, and the invention finds preferable embodiment in, the chair structure hereinafter particularly described and illustrated by the accompanying drawing, wherein:

Figure 1 is a perspective view of a chair structure of the type commonly installed in intracity transit motorbusses, supported on a pair of pedestals constructed according to the present invention;

Figure 2 is a fragmentary view of the same shown partly in side elevation and partly in longitudinal, central vertical section through one of the supporting pedestals;

Figure 3 is a horizontal sectional view taken on line 3--3 of Figure 2; and

Figure 4 is a plan view of a unitary sheet metal blank from which the supporting pedestal is fabricated.

Referring now in detail to these drawings wherein like parts are designated by the same numerals in the several views, the chair structure there shown comprises a conventional, up holstered chair seat I0 and chair back I I mounted in conventional manner on a, tubular metal supporting frame I2 having substantially horizontal and parallel tubular front and rear cross bars designated I3 and I 4 respectively upon which rest the chair seat Ill.

The frame I2 of the chair structure is supported by a pair of spaced pedestals generally designated I5 and each fabricated in accordance with the invention from a unitary sheet-metal blank as shown per se in Figure 4. This blank is bent to form an upright tubular member having parallel, vertical side walls I6 connected by a semi-cylindrical front wall I1, the rearward ends of the metal sheet being turned inwardly as at I8 and butt-welded together to form a semi-cylindrical rear wall. The upper edges of the side walls II; of the pedestal slope rearwardly-downwardly and are slightly crimped as at I9 and 20 to form seats in which rest the front cross-bar l 3 and rear cross-bar I4, respectively, of the chair frame.

The front wall I! of each pedestal has an extension 2I onits upper end which is curled rearwardlyover and around the tubular front crossbar I3 of the chair frame and welded thereto, and the rear wall of each pedestal has similar extensions 22 which are curled forwardly over and around the tubular rear cross-bar I4 of the chair frame and welded thereto.

The lower ends of the side walls l6 of each pedestal are flanged outwardly to form feet 23 which are provided with apertures 24 therein for the reception of bolts 25 by means of which the pedestal may be secured to the floor of a vehicle.

It will thus be seen that the present invention provides a unitary supporting pedestal for a chair structure, which pedestal is simply and economically constructed, efficient in its intended function and attractive in appearance, and while but one specific embodiment of the invention has been herein shown and described it will be understood that many details thereof may be altered or omitted without departing from the spirit of the invention as defined by the following claims.

I claim:

1. In combination with a chair structure having a seat-supporting frame comprising substantially horizontal and parallel front and rear cross-bars, a supporting pedestal for said frame comprising an upright tubular member having spaced vertical side Walls supporting on their upper forwaird edges said front cross-bar at spaced points thereon and supporting on their upper forward edges said front cross-bar at spaced points thereon, said tubular member having an extension on the upper end of its front wall curled over the top of the front cross-bar and secured thereto and an extension on the upper end of its rear Wall curled over the top of the rear cross-bar and secured thereto.

2. In combination with a chair structure having a seat-supporting frame comprising substantially horizontal and parallel front and rear cross-bars, a supporting pedestal for said frame comprising an upright tubular member having spaced vertical side walls supporting on their upper forward edges said front cross-bar at spaced points thereon and supporting on their upper rearward edges said rear cross-bar at spaced points thereon, said tubular member having an extension on the upper end of its front wall curled over the top of the front cross-bar and secured thereto and an extension on the upper end of its rear wall curled over the top of the rear cross-bar and secured thereto, and said tubular member having feet extending outwardly 3 a from the lower ends of its opposite side walls and adapted for attachment to a supporting floor.

3. In combination with a chair structure having a, seat-supporting frame comprising substantially horizontal and parallel front and rear crossbars, a supporting pedestal for said frame comprising a unitary sheet of metal bent to form an upright tubular member having spaced vertical side walls supporting on their upper forward edges said front cross-bar at spaced points thereon and supporting on their upper rearward edges said rear cross-bar at spaced points thereon and a connecting front wall, and having its rearward ends turned inwardly and'butt-welded'together to form a rear wall, said tubular member having an integral extension on the upper end of its front wall curled over the top of the front cross-bar and secured thereto and an integral extension on the upper end of its rear wall curled over the top of the rear cross-bar and secured thereto.

4. In combination with a chair structure having a seat-supporting frame comprising substan-' tially horizontal and parallel front and rear cross-bars, a supportingpedestal forsaid frame comprising a unitary sheet of metal bent to form an upright tubular member having spaced .vertibar and secured thereto and an integral extension on the upper end of its rear wall curled over the top of the rear cross-bar and secured thereto, and said tubular member having feet flanged outwardly from the lower ends of its side walls and adapted for attachment to a supporting floor.
