Appl. No.:

5/638339

Inventors:

Richard W. Sitler - Costa Mesa CA

Assignee:

Plan Hold Corporation - Irvine CA

International Classification:

A47B 6300
B42F 1500

US Classification:

312184

Abstract:

A single point suspension device for filing sheet material in parallel vertical planes within or without a cabinet construction in which a horizontal support bar has a sidewardly opening longitudinal recess defined in part by a sidewardly extending hook and in which is received a suspension member attached to upper edge margins of sheet material to be filed. The suspension member includes a sidewardly directed recess defined in part by a hook, the hooks and recesses of the suspension member and the support bar being correspondingly configured for substantially complete interlocking interengagement along correspondingly configured surfaces and whereby the interengagement is accomplished with relative horizontal movement of the bar and suspension member, and wherein the interlocking engagement restricts angular relative movement of the support bar and suspension member. A cabinet construction having a chamber with side vertical frame members provided with sets of vertically spaced openings and detachable clip members for cooperable reception within said openings in said vertical frame members to vertically adjustable position a support bar having longitudinal grooves cooperable with spaced lateral walls on said clip members for holding said support bar at a selected height within said chamber. One or more support bars are provided in vertically spaced relation, the space interval being only slightly greater than the height of the sheet material to be filed and the height of the interlocked suspension member and support bar whereby unused space within the cabinet chamber between tiers of vertically filed sheet material is substantially minimized.

Abstract:

A filing system for supporting material to be filed in vertical zones, such material being single sheet material, multiple sheet material held in a binder, vertically arranged horizontally extending pockets or compartments of single or multiple form. A support bar is positioned transversely of the vertical filing zones and supported at opposite ends, the support bar having a longitudinally extending web in a vertical plane normal to said vertical zone and having dihedrally disposed flanges extending from said web along its length in opposite directions. The flanges are shaped to provide upwardly facing bearing contact areas and downwardly facing bearing contact areas spaced from the vertical plane, each downwardly facing contact area being located to be cooperable with an upwardly facing contact area on the opposite side of the vertical plane to provide a set of bearing contact areas for supporting a suspension means connected to the material to be filed. The cross sectional shape of the support bar is adapted to cooperate with a suspension means which utilizes one set of bearing contact areas and also a suspension means which is adapted to utilize two sets of bearing contact means. A support bar which can be readily reinforced against bending.
