Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
112 words
Wall fixture, comprising: a. a pair of rails adapted to be mounted on a wall in spaced, parallel relationship, each rail being formed with a plurality of inclined slots, and b. an appliance extending between the rails, the appliance having a main body with a surface facing the rails and having a horizontally-extending fin extending from the surface and lying in a slot of each of the rails, each of the fins having a tapered cross-sectional shape and being wider adjacent the wall from which it extends than at the portion more remote from the wall, the shape of the slots and the cross-sectional shape of the fin being substantially the same.
Claim 2
Dependent Claim
112 words
Wall fixture, comprising: a. a pair of rails adapted to be mounted on a wall in spaced, parallel relationship, each rail being formed with a plurality of inclined slots, and b. an appliance extending between the rails, the appliance having a main body with a surface facing the rails and having a horizontally-extending fin extending from the surface and lying in a slot of each of the rails, each of the fins having a tapered cross-sectional shape and being wider adjacent the wall from which it extends than at the portion more remote from the wall, the shape of the slots and the cross-sectional shape of the fin being substantially the same.
Claim 3
Dependent Claim
22 words
Wall fixture as recited in claim 1, wherein the main body and fin of the appliance are integrally formed of injection-molded plastic.
Claim 4
Dependent Claim

Claim 5
Dependent Claim
37 words
Wall fixture as recited in claim 3, wherein each wall has a flat, outwardly-directed surface, the fins on each surface being inclined at an acute angle to the surfaces and directed toward the junction between the walls.
Claim 6
Dependent Claim
37 words
Wall fixture as recited in claim 4, wherein each wall has the shape of an elongated rectangle, the walls being joined along long sides, and wherein a triangular end wall joins each set of adjacent short sides.
