Abstract

Abstract An improvement on an angled structural member comprises an elongated member with an "L-shape" cross section. The said member has a smooth face in the outer surface on one hand, and a plurality of recesses in the inner face on the other hand. Each of the recesses further includes a circular cavity which remains an integrated thin wall at one end of the cavity.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 134 words
A structural member extending in a longitudinal direction having a substantially L-shaped cross-sectional contour forming a pair of substantially orthogonally directed leg members, each of said leg members having opposing sides forming an inner surface and an outer surface defining a thickness dimension of said leg members, each of said leg outer surfaces forming a planar contour and each of said inner surfaces having formed therethrough a plurality of blind openings defined by a plurality of first recesses having a first opening recess dimension and a plurality of second recesses aligned with respective ones of said first recesses and having a second opening recess dimension less than said first opening recess dimension, each of said first and second recesses in combination having a thickness dimension less than said thickness dimension of said leg members.
Claim 2
Dependent Claim 134 words
A structural member extending in a longitudinal direction having a substantially L-shaped cross-sectional contour forming a pair of substantially orthogonally directed leg members, each of said leg members having opposing sides forming an inner surface and an outer surface defining a thickness dimension of said leg members, each of said leg outer surfaces forming a planar contour and each of said inner surfaces having formed therethrough a plurality of blind openings defined by a plurality of first recesses having a first opening recess dimension and a plurality of second recesses aligned with respective ones of said first recesses and having a second opening recess dimension less than said first opening recess dimension, each of said first and second recesses in combination having a thickness dimension less than said thickness dimension of said leg members.
Claim 3
Dependent Claim 52 words
The structural member as recited in claim 1 where each of said first recess opening dimensions define a predetermined polygonal contour for mating insert therein of a fastening nut substantially having said predetermined polygonal contour for mounting said fastening nut within said first recess and preventing rotation of said fastening nut therein.
Claim 4
Dependent Claim 17 words
The structural member as recited in claim 2 where said predetermined polygonal contour is a hexagonal contour.
Claim 5
Dependent Claim 29 words
The structural member as recited in claim 1 where each of said second recesses define a base section adapted to be removed by impact thereon of an impact member.
Claim 6
Dependent Claim 49 words
The structural member as recited in claim 1 including indicia formed on said leg inner surface forming a plurality of spaced apart marking line indicia for (1) aligning one of said structural members to another of said structural member, and, (2) providing a longitudinal measure of said structural member.
Claim 7
Dependent Claim 34 words
The structural member as recited in claim 5 where said plurality of spaced apart marking line indicia form a plurality of mutually orthogonal and intersecting marking lines inscribed within a respective leg inner surface.
Claim 8
Dependent Claim 33 words
The structural member as recited in claim 5 where said plurality of said spaced apart marking line indicia includes a plurality of numerical scale indicia for labeling said spaced apart marking line indicia.
