1 Claim.

The present invention relates to seat structures and more particularly to chairs which are especially adapted for ready installation in base ball parks, grandstands and other outdoor sports '5 arenas.

The primary objects of the instant invention are to provide a seat of the character above indicated which may be conveniently installed for use; to provide such a seat having means for adjustably fitting the seat adjacent a vertical riser in installation; and, to provide such a seat which isutilitarian and comfortable in use, simple and rugged in construction and economical in manufacture.

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

Figure 1 is a fragmentary perspective View of the seat or chair;

Figure 2 is a fragmentary side elevational view of the chair leg;

Figure 3 is a face view of one of a pair of chair leg supporting brackets; and

Figure 4 is a fragmentary side elevational View of the manner in which the chair supporting member is secured to a vertical wall surface of a grandstand or the like and the manner in which the chair or seat is adjustably fitted to its supporting member.

Referring then to the drawing in which like parts of the seat structure and its supporting means are designated by the same numerals in the several views, a chair adapted for installation in baseball parks, grandstands and the like i has a folding seat In secured to hingedly connected seat supporting brackets ll mounted upon the chair frame I2, here shown as of cast metal, and a back i3 is secured to the seat back supporting uprights M as by bolts I5.

The chair is preferably provided with a pair of spaced depending legs l6 which are extensions of the seat back supporting uprights l4. Each leg has an upper longitudinally slotted portion ll therein and a lower apertured portion Ill. The inner face of each slotted portion is provided with horizontally disposed serrations l9 which are in a vertically disposed series, all as best shown in Figure 1. j

A pair of chair leg supporting brackets 20 are provided, here shown as of cast metal and adapted to be secured adjacent a vertical riser 2| of concrete or the like, and in spaced horizontal position in the manner hereinafter set forth. These brackets 20 are each provided with an aperture 22 therein and the outer face of each aperture is provided with horizontally disposed serrations 23 which are in vertically disposed series, all as best shown in Figure 3.

Means for securing each bracket 20 adjacent the vertical riser 2i in spaced horizontal position and for securing each leg l6 of the chair to 5 a bracket 20 in vertically adjusted position comprise expansion bolts 24 projecting from the riser 2| and respectively extending through the aperture 22 of each bracket and through the slotted portion ll of each leg and similar bolts 25 which 10 likewise project from the riser 2| and respectively extend through the aperture portion ill of each leg. The ends of the expansion bolts 24 which extend through respective portions l1 and 22 in each chair leg l6 and the expansion bolts 25 are 15 threaded to receive the nuts by means of which the chair legs are respectively pressed into gripping contact with the bracket 20 and the riser 2| respectively.

The chairs are installed in the following man- 20 ner: the desired height of the seats having been determined, the expansion bolts are accordingly inserted into the riser. In cases where it is desired that the seats be installed relatively high with reference to the riser, the upper bolts are 25 embedded near the top of the riser, and the lower bolts are so disposed that the upper bolts extend through near the bottom of the slots in portions H. In cases where it is desired that the seats be installed relatively low, the lower bolts are em- 30 bedded near the bottom of the riser, and the upper bolts are so disposed that they extend through near the top of the slotted portions I! to insure maximum bracing, but in cases where the risers are so low that this is impracticable, the 5 upper bolts are disposed lower.

The bracket 20 and the slotted portion I! have serrated portions to insure a positive engagement therebetween. In cases wherein the bolts 24 extend through the slotted portions I! at any point 40 other than near the top of the slot, and in the absence of such positive engagement, the entire downward thrust of the chair leg depends on the lower bolt. In fact, this engagement between these serrated portions makes possible the entire 5 elimination of the lower bolts, though obviously the support is strengthened by their inclusion.

A further purpose of the slotted portion I1 is to allow compensation for incidental variations in the distance between each vertically aligned pair 50 of bolts.

While but one specific embodiment of this invention has been herein shown and described, it will be understood that certain details of the construction shown may be altered or omitted with- 55 out departing from the spirit of this invention as defined by the following claim.

We claim: The combination with a vertical riser having 5 an upper pair of horizontally spaced laterally projecting bolts and a lower pair of bolts respectively parallel to and in vertical alignment with the upper pair, each of the four bolts being screw threaded to receive a securing nut, and an aper- 10 tured serrated supporting bracket embracing the shank of each upper bolt, of a chair provided with ERVING B.
