Abstract
Abstract A cantilever storage rack section comprises a vertical post having flat side walls joined by a central web. A bracket for supporting a horizontal load-bearing member comprises two overlapping portions and is clamped onto one side wall of the vertical post by a bolt extending through the overlapping portions. One of the overlapping portions includes a plurality of apertures interconnected by a slot, and the other portion contains a threaded aperture, whereby the width of the bracket may be adjusted by registering different apertures of the two bracket portions.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
202 words
A cantilever storage rack section comprising: a vertical post; a bracket comprising first and second overlapping front walls and first and second rear walls; a first transverse wall interconnecting the first front wall and the first rear wall and a second transverse wall interconnecting the second front wall and the second rear wall; the rear walls being in contact with a rear surface of the post and one of the front walls being in contact with the front surface of the post; a first substantially horizontal load-bearing member bonded to the first transverse wall and extending from the bracket, and a second substantially horizontal load-bearing member bonded to the second transverse wall and extending from the bracket, said load-bearing members being located near an upper edge of the bracket; a bolt located between said load-bearing members and extending through circular openings in the overlapping front walls and abutting against the front surface of the post; and said openings being located in an upper portion of the bracket, and at least one of the openings being threaded, whereby advancement of the bolt secures together the two overlapping front walls of the bracket and clamps a lower edge of the bracket to the post.
Claim 2
Dependent Claim
202 words
A cantilever storage rack section comprising: a vertical post; a bracket comprising first and second overlapping front walls and first and second rear walls; a first transverse wall interconnecting the first front wall and the first rear wall and a second transverse wall interconnecting the second front wall and the second rear wall; the rear walls being in contact with a rear surface of the post and one of the front walls being in contact with the front surface of the post; a first substantially horizontal load-bearing member bonded to the first transverse wall and extending from the bracket, and a second substantially horizontal load-bearing member bonded to the second transverse wall and extending from the bracket, said load-bearing members being located near an upper edge of the bracket; a bolt located between said load-bearing members and extending through circular openings in the overlapping front walls and abutting against the front surface of the post; and said openings being located in an upper portion of the bracket, and at least one of the openings being threaded, whereby advancement of the bolt secures together the two overlapping front walls of the bracket and clamps a lower edge of the bracket to the post.
Claim 3
Dependent Claim
42 words
The storage rack of claim 1 wherein: the first front wall contains a plurality of first circular openings, whereby the width of the bracket may be adjusted by registering any of the first openings with the opening in the second front wall.
Claim 4
Dependent Claim
108 words
The storage rack of claim 2 wherein: the first circular openings are interconnected by a slot; and the bolt has a narrow dimension defined between opposite flat surfaces that is smaller than the width of the slot, and a thick dimension defined between opposite threaded surfaces which is larger than the width of the slot, whereby the bolt may be moved through the slot to communicate with any of the first circular openings by rotating it such that its flat surfaces are parallel to the slot, and may be locked in any of the openings by rotating it such that its flat surfaces are perpendicular to the slot.
Claim 5
Dependent Claim
42 words
The storage rack of claim 1 wherein: the rear walls of the bracket each constitute part of an angle member having a wall perpendicular to the rear wall which is bonded to an inner surface of the transverse wall of the bracket.
Claim 6
Dependent Claim
42 words
The storage rack of claim 4 wherein: the first front wall and first transverse wall together constitute an integral angle member having flat surfaces; and the second front wall and second transverse wall constitute a second integral angle member having flat surfaces.
Claim 7
Dependent Claim
32 words
The storage rack of claim 4 wherein: the load-bearing member comprises two U-shaped members which are respectively bonded to the outer surface of the first and second transverse walls of the bracket.
Claim 8
Dependent Claim
42 words
The storage rack of claim 6 wherein: the first front wall contains a plurality of first circular openings, whereby the width of the bracket may be adjusted by registering any of the first openings with the opening in the second front wall.
Claim 9
Dependent Claim
108 words
The storage rack of claim 7 wherein: the first circular openings are interconnected by a slot; and the bolt has a narrow dimension defined between opposite flat surfaces that is smaller than the width of the slot and a thick dimension defined between opposite threaded surfaces which is larger than the width of the slot, whereby the bolt may be moved through the slot to communicate with any of the first ciRcular openings by rotating it such that its flat surfaces are parallel to the slot, and may be locked in any of the openings by rotating it such that its flat surfaces are perpendicular to the slot.
Claim 10
Dependent Claim
37 words
The storage rack of claim 8 wherein: the end of the bolt opposite the vertical post contains an index line, whereby an operator can ascertain whether the flat surfaces of the bolt are parallel to the slot.
Claim 11
Dependent Claim
191 words
An adjustable width bracket comprising: a first member comprising a first front wall and a perpendicular transverse wall; a second member comprising a second front wall and a second transverse sidewall, said first and second transverse sidewalls being adapted to clamp against opposite sides of an object; the second front wall overlapping the first front wall and having a plurality of circular openings joined by a slot; the first front wall having a threaded opening in that portion which is coextensive with the second front wall; a bolt extending through the circular openings in the overlapping front walls; and said bolt having a narrow dimension defined between opposite flat surfaces that is smaller than the width of the slot and a thick dimension defined between opposite threaded surfaces which is larger than the width of the slot, whereby the bolt may be moved through the slot to communicate with any of the first circular openings by rotating it such that its flat surfaces are parallel to the slot and it may be locked in any of the openings by rotating it such that its flat surfaces are perpendicular to the slot.
Claim 12
Dependent Claim
191 words
An adjustable width bracket comprising: a first member comprising a first front wall and a perpendicular transverse wall; a second member comprising a second front wall and a second transverse sidewall, said first and second transverse sidewalls being adapted to clamp against opposite sides of an object; the second front wall overlapping the first front wall and having a plurality of circular openings joined by a slot; the first front wall having a threaded opening in that portion which is coextensive with the second front wall; a bolt extending through the circular openings in the overlapping front walls; and said bolt having a narrow dimension defined between opposite flat surfaces that is smaller than the width of the slot and a thick dimension defined between opposite threaded surfaces which is larger than the width of the slot, whereby the bolt may be moved through the slot to communicate with any of the first circular openings by rotating it such that its flat surfaces are parallel to the slot and it may be locked in any of the openings by rotating it such that its flat surfaces are perpendicular to the slot.
Claim 13
Dependent Claim
60 words
The bracket of claim 10 wherein: the bolt comprises an enlarged end portion having a diameter that is greater than the diameter of any of the slots; and the end of the enlarged portion contains an index line parallel to the flat surfaces of the bolt, whereby an operator can ascertain whether the flat surfaces are parallel to the slot.
