Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 163 words
A shelf-support system of modular construction comprising a plurality of serially connected bracket members, said bracket members comprising substantially planar structures having an L-shaped cross-section, said bracket members further comprising a longer, plate-like vertical support member, said vertical support member integral at the top horizontal edge thereof with a horizontally extending longitudinally extending shelf-support member, said shelf-support member tapered toward its outer end to define a substantially triangular shape, and a flexible, severable connector portion located intermediate said bracket members and integral with the vertical edges of said vertical members whereby each of said brackets is detachably attached in flexible fashion to form a longitudinally extended support structure, and said system is adapted to bend to a 90-degree angle with respect to itself to provide support to a shelf member at the junction of two walls by the flexure of said connector between said segments, and said system is selectively severable to a desired longitudinal extension by the fracture of said connector portion.
Claim 2
Dependent Claim 163 words
A shelf-support system of modular construction comprising a plurality of serially connected bracket members, said bracket members comprising substantially planar structures having an L-shaped cross-section, said bracket members further comprising a longer, plate-like vertical support member, said vertical support member integral at the top horizontal edge thereof with a horizontally extending longitudinally extending shelf-support member, said shelf-support member tapered toward its outer end to define a substantially triangular shape, and a flexible, severable connector portion located intermediate said bracket members and integral with the vertical edges of said vertical members whereby each of said brackets is detachably attached in flexible fashion to form a longitudinally extended support structure, and said system is adapted to bend to a 90-degree angle with respect to itself to provide support to a shelf member at the junction of two walls by the flexure of said connector between said segments, and said system is selectively severable to a desired longitudinal extension by the fracture of said connector portion.
Claim 3
Dependent Claim 24 words
The shelf-support system of claim 1 wherein said vertical support member and said shelf-support member are each provided with at least one hole therethrough.
Claim 4
Dependent Claim 27 words
The shelf-support system of claim 1 wherein said vertical support member and shelf-support member are provided on the outer surfaces thereof with a layer of pressure-sensitive adhesive.
Claim 5
Dependent Claim 28 words
The system as recited in claim 1 in which said connector portion comprises a plurality of parallel, linear, reduced-thickness portions each formed of a multiplicity of perforated holes.
Claim 6
Dependent Claim 20 words
The system as recited in claim 4 in which said reduced-thickness portions are each formed of a plurality of spot-welds.
Claim 7
Dependent Claim 26 words
The system as recited in claim 1 in which said conductor portion comprises a second material of crease-bendable and breakable characteristics medially disposed between each segment.
Claim 8
Dependent Claim 23 words
The shelf-support system as recited in claim 1 in which the horizontal outer surfaces of each segment exhibits a layer of pressure adhesive.
