Claim 1
Independent Claim
152 words
Wall fixture, comprising: (a) a molded plastic rail adapted to be fastened to a wall surface in a vertical aspect, the rail being formed with a plurality of narrow slots which enter a broad vertical front surface of the rail facing away from the wall surface, each slot extending inwardly and at a substantial angle to the vertical rail being formed with spaced, parallel side surfaces lying at right angles to the said vertical front surface, (b) a molded plastic shelf-element having a broad vertical rear surface adapted to lie against the said front surface of the rail, having a plurality of thin ribs extending from the said rear surface for locking engagement with corresponding slots in the rail, and having two vertical flanges lying on either side of and integral with at least one of the ribs in spaced parallel relationship and closely embracing the said side surfaces of the rail.

Wall fixture as recited in claim 1, wherein the flanges are non-coextensive, the lower end of one flange being integral with one side of a rib, while the upper end of the other flange is integral with the other side of the same rib.
Claim 5
Dependent Claim
40 words
Wall fixture as recited in claim 1, wherein the shelf-element includes a rear wall, a bottom wall extending at a right angle to the rear wall, and a pair of spaced parallel side walls joining the rear and bottom walls.
Claim 6
Dependent Claim
95 words
Wall fixture as recited in claim 1, wherein the shelf-element is a bracket having a rear wall with the said rear surface on one side and a front surface, a vertical web wall extending at a right angle to the said front surface of the rear wall, the web wall having a generally right triangular shape, a flange extending outwardly from the periphery of the web wall, and a plurality of flanges extending across the web wall from one part of the peripheral web wall from one part of the peripheral web to another part.
Claim 7
Dependent Claim
44 words
Wall fixture as recited in claim 5, wherein the vertex of the triangular web wall away from the rear wall is rounded, and wherein the upper edge flange has a flat horizontal surface for supporting a shelf and terminates in an upwardly-extending stop abutment.
