Abstract
Abstract An illustrative embodiment of the invention is directed to a compartmented rack for storing photographic slides. The slides are housed in individual compartments in which the edges of the slide frames in a row of frames form an overlapping, longitudinal, scale-like array with the adjacent row. Angular stops are formed in each of the compartments above the individual slides to retain each slide in its compartment without regard to the angular orientation of the slides and rack or the effect of some inadvertent impact.

Total Claims: 7
Claim 1
Independent Claim
227 words
A rack having a transverse front and rear for the individual storage of slides in compartments comprising a latticework of longitudinal and transverse ribs arranged on edge, adjacent pairs of longitudinal ribs being spaced from each other by a distance that corresponds to the width of a slide, adjacent pairs of transverse ribs being spaced from each other by a distance that is sufficient to establish an overlapping scale-like storage of the slides in longitudinal rows between the longitudinal ribs, the transverse ribs, each having respective heights that are not as great as the heights of the longitudinal ribs, the bottom surface of each compartment formed by adjacent pairs of longitudinal and transverse ribs being cut out to provide a narrow bottom ledge on the transverse ribs that are oriented toward the front in each of of the compartments, slide edges being formed on the longitudinal ribs in each compartment, the slide edge being inclined from the upper edge of one of the transverse ribs downwardly and forwardly toward the bottom ledge of said compartment, an angular stop formed on at least one of said longitudinal ribs in each of the compartments, each of the angular stops being open toward the respective transverse rib, from which the slide edge is inclined and the rack further having an outer contour that is provided with slide and grip ledges.
Claim 2
Dependent Claim

A rack having a transverse front and rear for the individual storage of slides in compartments comprising a latticework of longitudinal and transverse ribs arranged on edge, adjacent pairs of longitudinal ribs being spaced from each other by a distance that corresponds to the width of a slide, adjacent pairs of transverse ribs being spaced from each other by a distance that is sufficient to establish an overlapping scale-like storage of the slides in longitudinal rows between the longitudinal ribs, the transverse ribs, each having respective heights that are not as great as the heights of the longitudinal ribs, the bottom surface of each compartment formed by adjacent pairs of longitudinal and transverse ribs being cut out to provide a narrow bottom ledge on the transverse ribs that are oriented toward the front in each of of the compartments, slide edges being formed on the longitudinal ribs in each compartment, the slide edge being inclined from the upper edge of one of the transverse ribs downwardly and forwardly toward the bottom ledge of said compartment, an angular stop formed on at least one of said longitudinal ribs in each of the compartments, each of the angular stops being open toward the respective transverse rib, from which the slide edge is inclined and the rack further having an outer contour that is provided with slide and grip ledges.
Claim 3
Dependent Claim
64 words
A rack according to claim 1, wherein the angular stops are arranged in the front of each compartment each stop having a shorter arm which establishes a ledge that forms a surface portion of the rack, and a longer arm which is perpendicular to the shorter arm and extends approximately to the mid-height of the longitudinal rib on which said angular stop is formed.
Claim 4
Dependent Claim
27 words
A rack according to claim 1, wherein the slide edges that are formed on the longitudinal ribs extend longitudinally over the rear two-thirds of each respective compartment.
Claim 5
Dependent Claim
33 words
A rack according to claims 2 or 3, wherein the angular stops are arranged above the spaces formed by the free ends of the slide edges and the respective associated narrow bottom ledges.
Claim 6
Dependent Claim
32 words
A rack according to claim 1 wherein the outer contour further comprises slide ledges that have adjacent to one of the grip ledges one cog-like projection on each of the slide ledges.
Claim 7
Dependent Claim
31 words
A rack according to claim 1, wherein each of the gripping ledges of the outer contour each have at least one continuous hole formed therein, said holes being in longitudinal alignment.
