Abstract
Abstract One or more (preferably two) floor-supported post-mounting stringers, each comprising parallel, conventional structural steel confronting channels, rigidly united by spanner plates welded at their ends to the lower channel webs in abutting relation therewith. Tubular posts have footings on their lower ends which are insertable downwardly between the channels of a stringer and rotatable into locking engagement with the stringer at any desired lengthwise location on the latter. Posts are thus conveniently spaced along each stringer to form rack bins between the posts for holding, on edge, any desirable number of flat cases of heavy material, such as plat glass, and the like.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
167 words
In an expansible storage rack for supporting above the floor large flat cases of heavy material such as plate glass, the combination of: plural stringer means, resting, when in use directly on a flat floor, each stringer thereof including a pair of conventional parallel steel channels each of which has a vertical middle web and upper and lower horizontal webs, said channels being held in spaced confrontation by flat transverse spanner plates, spaced longitudinally of the stringer, with the plate ends secured to the lower horizontal channel webs, and post means, each post of which has a footing on end end which is longer than its width, said width permitting said footing to be inserted downwardly between said channEls, the depth of said footing being such as to permit the same to be extended laterally into both channels to snugly fit the vertical spaces between said horizontal webs by rotating said post to lock said footing in position in said stringer and hold said post rigidly upright.
Claim 2
Dependent Claim
167 words
In an expansible storage rack for supporting above the floor large flat cases of heavy material such as plate glass, the combination of: plural stringer means, resting, when in use directly on a flat floor, each stringer thereof including a pair of conventional parallel steel channels each of which has a vertical middle web and upper and lower horizontal webs, said channels being held in spaced confrontation by flat transverse spanner plates, spaced longitudinally of the stringer, with the plate ends secured to the lower horizontal channel webs, and post means, each post of which has a footing on end end which is longer than its width, said width permitting said footing to be inserted downwardly between said channEls, the depth of said footing being such as to permit the same to be extended laterally into both channels to snugly fit the vertical spaces between said horizontal webs by rotating said post to lock said footing in position in said stringer and hold said post rigidly upright.
Claim 3
Dependent Claim
78 words
An expansible storage rack as recited in claim 1 wherein said spanner plates lie in the same plane with said lower channel webs and in abutting relation therewith and are welded to said webs whereby each channel can rest throughout its length directly on the floor and support said heavy cases spaced upwardly above the floor, and a post footing is free to be adjusted lengthwise anywhere in a stringer including areas in which spanner plates are located.
Claim 4
Dependent Claim
90 words
An expansible storage rack as recited in claim 1 wherein each post comprises a steel tube and each footing comprises a steel bottom plate welded to said tube and reinforcing skirts welded to opposite end edge portions of said bottom plate and extending downward therefrom to give said footing a depth to fit snugly within said channels, two diagonally opposed corners of said footing being rounded to facilitate the footing being rotated crosswise in a stringer, the opposite diagonal corners providing stops against continuing said rotation past said crosswise position.
Claim 5
Dependent Claim
66 words
An expansible storage rack as recited in claim 3 wherein the bottom plate is centrally apertured to allow a short lower end portion of the tube to extend therethrough after which said tube is welded to said plate; and a metal reinforcing strap underlying the bottom end of said tube and welded thereto, opposite ends of said strap extending to and being welded to said skirts.
