Abstract
Abstract In a shelving system having both vertical and oblique supports for removable shelves, identical shelves are interchangeably usable on either support by virtue of special tabs which are engageable with support slots in two possible ways. The same shelf, therefore, can be mounted horizontally on either the vertical or the oblique supports.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
325 words
A system of shelving wherein identical shelves may be mounted interchangeably on supporting members having surfaces disposed at different angles relative to the horizontal, said system comprising: a first support having a planar front surface disposed at a first angle with respect to the horizontal, and having a series of uniformly spaced slots extending in the vertical direction on said surface, a second support having a planar front surface disposed at a second angle with respect to the horizontal, said second angle being different from said first angle, and having a second series of uniformly spaced slots extending in the vertical direction on said surface, and first and second substantially identical shelves, each having an article-supporting surface and at least two tabs one located above the other and both adapted to extend into slots in said supports, the uppermost of said tabs having means for engaging the rear surfaces of said supports, means defining a first surface adapted to engage the planar front surface of one of the supports, and means, on the other of said tabs, defining a second surface adapted to engage the planar front surface of the other of said supports, and said first shelf being supported on said first support with its said uppermost tab extending into a slot of said first support and with its said first surface engaged with the planar front surface of said first support, said second shelf being supported on said second support with its uppermost tab extending into a slot of said second support and with its said second surface engaged with the planar front surface of said second support, and said first and second surfaces on each shelf being so related to each other and to the front surfaces of said first and second supports that, with said shelves so mounted respectively on said first and second supports, the article-supporting surface of the first shelf is substantially parallel to that of the second shelf.
Claim 2
Independent Claim
325 words
A system of shelving wherein identical shelves may be mounted interchangeably on supporting members having surfaces disposed at different angles relative to the horizontal, said system comprising: a first support having a planar front surface disposed at a first angle with respect to the horizontal, and having a series of uniformly spaced slots extending in the vertical direction on said surface, a second support having a planar front surface disposed at a second angle with respect to the horizontal, said second angle being different from said first angle, and having a second series of uniformly spaced slots extending in the vertical direction on said surface, and first and second substantially identical shelves, each having an article-supporting surface and at least two tabs one located above the other and both adapted to extend into slots in said supports, the uppermost of said tabs having means for engaging the rear surfaces of said supports, means defining a first surface adapted to engage the planar front surface of one of the supports, and means, on the other of said tabs, defining a second surface adapted to engage the planar front surface of the other of said supports, and said first shelf being supported on said first support with its said uppermost tab extending into a slot of said first support and with its said first surface engaged with the planar front surface of said first support, said second shelf being supported on said second support with its uppermost tab extending into a slot of said second support and with its said second surface engaged with the planar front surface of said second support, and said first and second surfaces on each shelf being so related to each other and to the front surfaces of said first and second supports that, with said shelves so mounted respectively on said first and second supports, the article-supporting surface of the first shelf is substantially parallel to that of the second shelf.
Claim 3
Dependent Claim
47 words
A system of shelving according to claim 1 in which said first and second surfaces are so related to each other and to said first and second supports that, with said shelves so mounted respectively on said first and second supports, both article-supporting surfaces are substantially horizontal.
Claim 4
Dependent Claim
24 words
A system of shelving according to claim 1 in which said other of said tabs extends rearwardly from said means defining a first surface.
Claim 5
Dependent Claim
55 words
A system of shelving in accordance with claim 1 in which said other of said tabs comprises a projection extending rearwardly from said means defining a first surface, and in which said second surface comprises a heel extending downwardly from said projection at a location between the end of said projection and said first surface.
Claim 6
Dependent Claim
27 words
A system of shelving according to claim 1 in which said other of said tabs of said second shelf extends into a slot on said second support.
Claim 7
Dependent Claim
38 words
A system of shelving according to claim 1 wherein the planar front surface of one of said supports is substantially vertical, and wherein the planar front surface of the other of said supports is oblique and upwardly facing.
Claim 8
Dependent Claim
55 words
A system of shelving according to claim 6 wherein the support having an oblique front surface constitutes part of a base for the system of shelving, and wherein the support having a substantially vertical front surface is removably secured to the upper end of said support having an oblique front surface and extends upwardly therefrom.
Claim 9
Dependent Claim
54 words
A system of shelving according to claim 6 wherein the support having an oblique front surface constitutes part of a base for the system of shelving, and wherein the support having a substantially vertical front surface is secured to the upper end of said support having an oblique front surface and extends upwardly therefrom.
Claim 10
Dependent Claim
47 words
A system of shelving according to claim 8 in which said first and second surfaces are so related to each other and to said first and second supports that, with said shelves so mounted respectively on said first and second supports, both article-supporting surfaces are substantially horizontal.
