Abstract
Abstract Shelving wherein bores are drilled in legs of channel-section-shaped shelving posts, between the legs of which is positioned channel-section-shaped crosspiece having obliquely downwardly and upwardly extending slotted crosspiece holes lying opposite the bores, and wherein a clamp bolt is placed in the bores in the slotted crosspiece holes, the bores and slotted crosspiece holes lying opposite one another.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
132 words
Erectable shelving comprising shelving posts, crosspieces, shelving bases, and clamp bolts, wherein said shelving posts each have channel-section-shaped legs and bores are drilled in the legs of the channel-section-shaped shelving posts, between the legs of at least two shelving posts there is placed a crosspiece, said crosspiece being of channel-section-shaped cross-section and having obliquely downwardly and outwardly extending slotted crosspiece holes lying opposite the bores in said legs, a clamp bolt being placed in the bores and in the slotted cross-piece holes, said bores and said slotted crosspiece holes lying opposite one another, and each of the channel-section-shaped shelving posts has at the outer ends of its legs a tubular section provided on the outside with bores and on the inside with slotted holes extending parallel to the flange in the legs.
Claim 2
Dependent Claim
132 words
Erectable shelving comprising shelving posts, crosspieces, shelving bases, and clamp bolts, wherein said shelving posts each have channel-section-shaped legs and bores are drilled in the legs of the channel-section-shaped shelving posts, between the legs of at least two shelving posts there is placed a crosspiece, said crosspiece being of channel-section-shaped cross-section and having obliquely downwardly and outwardly extending slotted crosspiece holes lying opposite the bores in said legs, a clamp bolt being placed in the bores and in the slotted cross-piece holes, said bores and said slotted crosspiece holes lying opposite one another, and each of the channel-section-shaped shelving posts has at the outer ends of its legs a tubular section provided on the outside with bores and on the inside with slotted holes extending parallel to the flange in the legs.
Claim 3
Dependent Claim
36 words
The shelving according to claim 1, characterized in that a clamp bolt is placed in the slotted holes and in the slotted crosspiece holes lying opposite thereto for force locking the shelving post and crosspiece together.
Claim 4
Dependent Claim

The shelving according to claim 1 or 2, characterized in that the bores and the slotted holes, as well as the slotted crosspiece holes, have a rectangular configuration.
Claim 5
Dependent Claim
37 words
The shelving according to claim 2 characterized in that each shelving base has provided therewith retaining rims, and a shelving base is placed with a retaining rim, which is bent away outwardly and downwardly, in the crosspiece.
Claim 6
Dependent Claim

The shelving according to claim 4, characterized in that the shelving base has a lateral rim which is bent away downwardly.
Claim 7
Dependent Claim
28 words
The shelving according to claim 1 or 2, characterized in that the crosspiece has at the outer ends of its legs an angular rim which is bent inwardly.
Claim 8
Dependent Claim
27 words
The shelving according to claim 1, or 2, characterized in that the crosspiece has at the outer ends of its legs lateral rims which are bent outwardly.
Claim 9
Dependent Claim
36 words
The shelving according to claim 1, or 2, characterized in that there are juxtaposed in a cross-piece a plurality of shelving bases spaced the proper distance from one another via a notch along their retaining rims.
Claim 10
Dependent Claim
31 words
The shelving according to claim 1, or 2, characterized in that two diagonal braces are placed between two shelving posts adjoining one another on one side of the shelving as erected.
Claim 11
Dependent Claim
22 words
The shelving according to claim 9, characterized in that the diagonal braces extend from a particular shelving post to the crossing point.
Claim 12
Dependent Claim

The shelving according to claim 4, characterized in that there is placed on a shelving base, bearing directly from above, a border strip, the boundary angle of which lies on the inside of one leg of the shelving post and a clamp bolt extends through the boundary hole in bores and/or slotted holes lying opposite one another.
Claim 13
Dependent Claim
43 words
The shelving according to claim 1 or 2, characterized in that the slotted hole is staggered with respect to the bore and the slotted crosspiece hole is staggered with respect to the slotted hole in the direction of fall of the clamp bolt.
Claim 14
Dependent Claim
50 words
The shelving according to claim 8, characterized in that the notch extends via the angular rim into the side of the crosspiece, on the edge of which is placed the supporting tongue which is disposed on the shelving-base rim bent away from the shelving base adjacent to the retaining rim.
Claim 15
Dependent Claim
143 words
The shelving according to claim 1, or 2, characterized in that there are arranged: (a) on the open side of each of the shelving posts in the tubular sections and adjacent to the slotted holes and to the bores therein, upper slots and lower slots; (b) each shelving base having shelving-base rims, retaining rims and retaining-head bores; (c) an upper slot with an upper tongue therein, and a lower slot with a lower tongue therein and in the retaining-head bores are retaining heads of a gusset plate which, by means of a pawl, more particularly in the shape of a spring placed on an inner-rim bead of the gusset plate and protruding with its tip through a spring slot into the duct of an inner-rim duct, is anchored against the inner rim which is bent away inwardly and upwardly toward the shelving base.
Claim 16
Dependent Claim
46 words
The shelving according to claim 14, characterized in that instead of a single gusset plate there is arranged a double gusset plate having lower tongues in the lower slots, an upper stabilization tongue and lower stabilization tongues being disposed in the duct of the shelving post.
