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
40 words
Wall fixture as recited in claim 1, wherein the appliance is a shelf whose main body has a first and a second wall extending at a right angle to each other, each wall being provided with a plurality of fins.
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.
Claim 7
Dependent Claim
18 words
Wall fixture as recited in claim 5, wherein one wall has a substantially wider wall than the other.
Claim 8
Dependent Claim
23 words
Wall fixture as recited in claim 6, wherein the edges of the walls remote from the junction are provided with an inwardly-directed lip.
Claim 9
Dependent Claim

Wall fixture as recited in claim 7, wherein integral ribs extend from the outer surface of each wall and extend between fins.
Claim 10
Dependent Claim
21 words
Wall fixture as recited in claim 8, wherein an outwardly-directed reinforcing flange extends completely around the free edges of the walls.
Claim 11
Dependent Claim
107 words
Wall fixture, comprising: a. a rail adapted to be mounted on a wall in vertical relationship, the rail being formed with a plurality of inclined slots, and b. an appliance attached to the rail, the appliance having a main body with a surface facing the rail and having horizontally-extending fins extending from the surface each fin lying in a slot of the rail, 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 12
Dependent Claim
107 words
