Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A display unit for mounting to a vertically disposed support structure each unit comprising: a. a plurality of exposed planar surfaces adapted for mounting to a vertically disposed support structure, at least each of the outer vertically mounting edges of said planar surfaces each having an outwardly projecting integrally formed, substantially hollow, vertically disposed channel, said planar surfaces integrally formed with and spaced by: b. substantially hollow wedge shaped cantilever shelves each shelf having: i. an upper outwardly extending surface disposed at right angles to and merging into a lower edge of an adjacent planar surface; ii. a sloped outwardly extending lower surface integrally connected to the upper surface along an outer edge thereof at an acute angle thereto and merging at the opposed end into an upper edge of an adjacent planar surface; and iii. a pair of outwardly extending wedge shaped end walls integrally formed with said upper surface and said lower surface along the width of each of said surfaces; said display unit being of unitized construction.
Claim 2
Dependent Claim
170 words
A display unit for mounting to a vertically disposed support structure each unit comprising: a. a plurality of exposed planar surfaces adapted for mounting to a vertically disposed support structure, at least each of the outer vertically mounting edges of said planar surfaces each having an outwardly projecting integrally formed, substantially hollow, vertically disposed channel, said planar surfaces integrally formed with and spaced by: b. substantially hollow wedge shaped cantilever shelves each shelf having: i. an upper outwardly extending surface disposed at right angles to and merging into a lower edge of an adjacent planar surface; ii. a sloped outwardly extending lower surface integrally connected to the upper surface along an outer edge thereof at an acute angle thereto and merging at the opposed end into an upper edge of an adjacent planar surface; and iii. a pair of outwardly extending wedge shaped end walls integrally formed with said upper surface and said lower surface along the width of each of said surfaces; said display unit being of unitized construction.
Claim 3
Dependent Claim
28 words
A display unit as claimed in claim 1 in which the width of the lowermost cantilever shelf exceeds the width of the remaining shelves of said display unit.
Claim 4
Dependent Claim
31 words
A display unit as claimed in claim 1 which includes at least one shelf having an upper surface disposed at a negative acute angle with respect to one said planar surface.
Claim 5
Dependent Claim
14 words
A display unit as claimed in claim 1 molded from glass fiber reinforced resin.
Claim 6
Dependent Claim
14 words
A display unit as claimed in claim 2 molded from glass fiber reinforced resin.
