Abstract
Abstract Brackets for mounting articles, such as shelves or panels, to a vertical wall or other supporting structure comprise first and second mutually orthogonal bracket portions to be secured, respectively, to the undersurfaces of the articles and to the walls. A keyhole shaped slot formed in one of the bracket portions enables the bracket to be conveniently coupled to a supporting screw anchored in the wall. The remaining bracket portion is secured to the undersurface of the shelf by screws or is coupled to a supporting screw by a keyhole shaped slot in the second bracket portion. Several different bracket embodiments enable systems of shelves or panels to be assembled by individuals having very little mechanical skill.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
135 words
A bracket for mounting an article to a support member, said bracket comprising a first portion to be secured to said article; and a second portion having a keyhole shaped opening formed therein large enough to receive a head of a fastener for mounting to said fastener extending from said support member, said first and second bracket portions being spaced apart from each other by shoulder means so as to lie in separate planes, said keyhole opening extending through said shoulder means between said first and second bracket portions and at least through a part of said second portion to establish a slot in the second portion, said slot tending to retain said fastener during application of a force to the fastener acting along a common longitudinal axis of the keyhole shaped opening and slot.
Claim 2
Dependent Claim
135 words
A bracket for mounting an article to a support member, said bracket comprising a first portion to be secured to said article; and a second portion having a keyhole shaped opening formed therein large enough to receive a head of a fastener for mounting to said fastener extending from said support member, said first and second bracket portions being spaced apart from each other by shoulder means so as to lie in separate planes, said keyhole opening extending through said shoulder means between said first and second bracket portions and at least through a part of said second portion to establish a slot in the second portion, said slot tending to retain said fastener during application of a force to the fastener acting along a common longitudinal axis of the keyhole shaped opening and slot.
Claim 3
Dependent Claim
62 words
The bracket of claim 1, wherein said first bracket portion comprises a pair of coplanar, outwardly extending plate members formed, respectively, at first and second shoulders located at opposite ends of said second bracket portion, the longitudinal axis of said keyhole opening extending between said plate members, said slot being longitudinal and enclosed at one end thereof opposite the keyhole shaped opening.
Claim 4
Dependent Claim
92 words
The bracket of claim 1, wherein said second bracket portion is formed with first and second mutually orthogonal sections, said first section being parallel to said first bracket portion, the first bracket portion contacting the lower surface of the article, the first section contacting an upper surface of the article, said second section containing the keyhole shaped opening and adapted to be coupled to a fastener in the support member, the shoulder being located between said second section and said first portion to provide clearance to recline the head of said fastener.
Claim 5
Dependent Claim
58 words
The bracket of claim 1, wherein said second bracket portion is formed with first and second parallel sections, said keyhole opening being provided in said first section of said second bracket portion, said second section of said second bracket portion being offset from said first section by a shoulder to provide clearance for the head of a fastener.
Claim 6
Dependent Claim
35 words
The bracket of claim 4, wherein an outer end of said second section is turned inwardly toward said first bracket portion, said second section being coplanar with the shoulder formed adjacent the first bracket portion.
Claim 7
Dependent Claim
84 words
A bracket for mounting an article to a support member, comprising first and second mutually orthogonal bracket portions, said first portion having formed therein a first keyhole shaped opening, an enlarged portion of said first keyhole shaped opening being formed at an intersection of said first and second bracket portions, said second bracket portion having formed therein a second keyhole shaped opening, an enlarged portion of said second keyhole shaped opening being positioned at an end of said second bracket portion opposite said intersection.
Claim 8
Dependent Claim
84 words
A bracket for mounting an article to a support member, comprising first and second mutually orthogonal bracket portions, said first portion having formed therein a first keyhole shaped opening, an enlarged portion of said first keyhole shaped opening being formed at an intersection of said first and second bracket portions, said second bracket portion having formed therein a second keyhole shaped opening, an enlarged portion of said second keyhole shaped opening being positioned at an end of said second bracket portion opposite said intersection.
Claim 9
Dependent Claim
21 words
The bracket of claim 6, including a third bracket portion extending between opposite ends of said first and second bracket portions.
Claim 10
Dependent Claim
20 words
The bracket of claim 6 or claim 7, wherein said first and second bracket portions are formed of plate members.
Claim 11
Dependent Claim
25 words
The bracket of claim 6, wherein said first and second bracket portions are formed of hollow material having a rectangular cross section for increased strength.
Claim 12
Dependent Claim
