Abstract
Abstract A track member having a bottom end portion resting on an upper surface of a support flange has a clip member slidably attached thereto for movement between a locking position and a releasing position for respectively preventing or permitting upward movement of the rail end portion with respect to the support flange. In the locking position of the clip member, a projecting tongue engages the bottom surface of the support flange opposite from the upper surface area on which the track member bottom end portion is supported. In the releasing position of the clip member, the tongue is clear of the support flange.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
149 words
A shelf for an order picking rack comprising: a generally rectangular frame including opposite side frame members and front and rear rails, said rails having flanges extending toward one another inwardly of said frame, an elongated track member having opposite bottom end portions supported on said flanges, a clip member slidably mounted on said track member adjacent at least one end thereof for sliding movement between locking and releasing positions, said clip member having a tongue projecting therefrom, said clip member in said locking position having said tongue located on the opposite side of one said flange from one said bottom end portion for preventing upward displacement of said one end portion, and said clip member in said releasing position thereof having said tongue located in spaced relationship to said flange along said track member for allowing free upward movement of said one end portion from said one flange.
Claim 2
Dependent Claim
149 words
A shelf for an order picking rack comprising: a generally rectangular frame including opposite side frame members and front and rear rails, said rails having flanges extending toward one another inwardly of said frame, an elongated track member having opposite bottom end portions supported on said flanges, a clip member slidably mounted on said track member adjacent at least one end thereof for sliding movement between locking and releasing positions, said clip member having a tongue projecting therefrom, said clip member in said locking position having said tongue located on the opposite side of one said flange from one said bottom end portion for preventing upward displacement of said one end portion, and said clip member in said releasing position thereof having said tongue located in spaced relationship to said flange along said track member for allowing free upward movement of said one end portion from said one flange.
Claim 3
Dependent Claim
43 words

Claim 4
Dependent Claim
48 words
The shelf of claim 2 wherein said tongue has a beveled front end portion which slopes upward to intersection with said tongue upper surface from a tongue front edge which is spaced from said track bottom surface a distance substantially greater than said predetermined thickness of said flange.
Claim 5
Dependent Claim
48 words
The shelf of claim 1 wherein said track member is of inverted generally U-shaped cross-sectional configuration including a top web and opposite legs depending therefrom, said legs having inwardly turned runners extending toward one another, said clip member having mounting means for slidably mounting same on said runners.
Claim 6
Dependent Claim
17 words

Claim 9
Dependent Claim
77 words
The shelf of claim 1 wherein said track member is of inverted generally u-shaped cross sectional configuration including a top web and opposite legs depending therefrom, said legs having inwardly turned runners extending toward one another, said clip member having mounting means for slidably mounting same on said runners, and opposite tabs extending outwardly from said clip beyond said legs of said track member for engagement by a persons fingers to slide said clip along said runners.
Claim 10
Dependent Claim
74 words
A one-piece plastic clip member for releasably locking an end of a track member on a support flange comprising: a generally flat clip body having outwardly opening opposite longitudinal grooves therein, said grooves having groove upper and lower side surfaces, a generally flat tongue projecting outwardly from one end of said body in a direction generally parallel to said grooves, said tongue having a tongue upper surface spaced below said groove lower side surfaces.
Claim 11
Dependent Claim
74 words
A one-piece plastic clip member for releasably locking an end of a track member on a support flange comprising: a generally flat clip body having outwardly opening opposite longitudinal grooves therein, said grooves having groove upper and lower side surfaces, a generally flat tongue projecting outwardly from one end of said body in a direction generally parallel to said grooves, said tongue having a tongue upper surface spaced below said groove lower side surfaces.
Claim 12
Dependent Claim
41 words
