Abstract
Abstract A maintenance-free anodized aluminum post having longitudinal grooves therein for mating with complementary brackets. The post is hollow and has a constant wall thickness. Each groove has a curved portion and a flat portion. The brackets may be moved in the grooves adjustably, and may be locked to the post without causing any deformation of the post or bracket.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
171 words
A post apparatus comprising: an elongated support member having a major longitudinal central axis and an outer periphery which includes at least one groove therein; said elongated support member having a tubular configuration which has a substantially constant wall thickness; said groove being disposed substantially parallel to said major longitudinal central axis of said elongated support member; said groove having an arcuate side wall portion and a substantially flat side wall portion; said substantially flat side wall portion of said groove being disposed in a flat plane which is oriented askew with respect to said major longitudinal central axis of said elongated support member; said groove including a flat base portion which is disposed in a flat plane that is oriented substantially perpendicular to a radius emanating from said major longitudinal central axis of said elongated support member; and none of said side wall portions of said groove of said elongated support member is disposed perpendicular to said flat plane within which said flat base portion of said groove is disposed.
Claim 2
Dependent Claim
171 words
A post apparatus comprising: an elongated support member having a major longitudinal central axis and an outer periphery which includes at least one groove therein; said elongated support member having a tubular configuration which has a substantially constant wall thickness; said groove being disposed substantially parallel to said major longitudinal central axis of said elongated support member; said groove having an arcuate side wall portion and a substantially flat side wall portion; said substantially flat side wall portion of said groove being disposed in a flat plane which is oriented askew with respect to said major longitudinal central axis of said elongated support member; said groove including a flat base portion which is disposed in a flat plane that is oriented substantially perpendicular to a radius emanating from said major longitudinal central axis of said elongated support member; and none of said side wall portions of said groove of said elongated support member is disposed perpendicular to said flat plane within which said flat base portion of said groove is disposed.
Claim 3
Dependent Claim
54 words
An apparatus according to claim 1, including: at least one third bracket member for mating with and interconnecting with said elongated support member; said third bracket member having a portion thereof provided with an arcuate shape which is configured and dimensioned to conform to and fit within said arcuate wall portion of said groove.
Claim 4
Dependent Claim
28 words
An apparatus according to claim 1, wherein: said arcuate wall portion of said groove intersects said substantially flat wall portion of said groove in an oblique dihedral angle.
Claim 5
Dependent Claim
34 words
An apparatus according to claim 1, wherein: said groove includes a second substantially flat wall portion which is disposed opposed to and substantially parallel to said first-mentioned substantially flat wall portion of said groove.
Claim 6
Dependent Claim
69 words
An apparatus according to claim 1, including: a first bracket member for mating with and interconnection with said elongated support member; said first bracket member having a first arm which is configured and dimensioned to fit within a first said groove of said elongated support member; said first bracket member having a second arm configured and dimensioned to fit within a second said groove of said elongated support member.
Claim 7
Dependent Claim
86 words
An apparatus according to claim 1, including: a first bracket member for mating with and interconnection with said elongated support member; said first bracket member having a first arm which is configured and dimensioned to fit within a first said groove of said elongated support member; said first bracket member having a second arm configured and dimensioned to fit within a second said groove of said elongated support member; and said first and second arms of said first bracket are oriented to converge toward each other.
Claim 8
Dependent Claim
82 words
An apparatus according to claim 1, including: a second bracket member for mating with and interconnecting with said elongated support member; said second bracket member having a first portion thereof which is configured and dimensioned to fit within said groove of said elongated support member; and said first portion of said second bracket member having diametrically-opposed and oppositely-facing arcuate surfaces each of which surface conforms substantially to the shape of said arcuate wall portion of said groove of said elongated support member.
Claim 9
Dependent Claim
23 words
An apparatus according to claim 7, wherein: said first portion of said second bracket member is provided with a threaded aperture extending therethrough.
