Abstract
Abstract The invention relates to a supporting arrangement for panlike or traylike articles, in which the structure takes the form of vertical columns arranged in laterally spaced pairs with the columns of each pair spaced in the fore-and-aft direction. The columns are fixedly interconnected at their upper and lower ends and the laterally spaced pairs of columns define spaces therebetween for receiving panlike or traylike articles. The articles are supported by horizontal guide members detachably connected to the pairs of columns on the support sides of the space. The structure can be stationarily mounted, or it may be provided with wheels on the bottom so that it is portable.

Claim 1
Independent Claim
319 words
In a supporting arrangement for slidably receiving traylike articles; a framework having pairs of vertical columns spaced in the lateral direction, the columns of each pair of columns being spaced in the fore-and-aft direction, said framework including horizontal structural elements extending between and fixedly connected to said columns and imparting rigidity to said framework, said laterally spaced pairs of columns defining therebetween a space open on the front side of the structure and adapted for a slidably receiving traylike articles, each said column having a recessed flange on the side thereof adjacent said space extending toward the other column of the respective pair of columns, each said column flange being recessed in the lateral direction a prescribed amount, each said column flange having horizontal slots formed therein and uniformly distributed along the respective column flange in the vertical direction, each slot having a vertical dimension Z, and at least one pair of guide members extending horizontally along the opposite lateral sides of said space and having leg elements extending into the lateral regions of said space for sliding supporting engagement with the undersides of the side edges of said articles introduced into said space, each guide member having a substantially vertical portion of a lateral thickness less than said prescribed recess whereby said vertical portion does not extend into the lateral regions of said space, said vertical portion connected to the said leg elements thereof and at its opposite ends engaging the flanges of the pair of columns on the same side of said space, each said vertical portion having offset angular portions on the upper and lower extremities thereof and extending through a pair of the said slots in said column flanges and engaging the sides of said flanges which face away from said space, the upper offset angular portion having a vertical dimension Y and the lower offset angular portion having a vertical dimension X where Y>Z>X.

Claim 3
Dependent Claim
47 words
A supporting element according to claim 1, in which each said guide member extends substantially to the bottoms of the said horizontal slots in the respective pair of columns so as to be prevented from any substantial amount of longitudinal movement relative to the pair of columns.
Claim 4
Dependent Claim
38 words
A supporting element according to claim 2, in which at least said columns and guide members are extruded aluminum alloy pieces each piEce having identical cross sections throughout its extent at points other than said column horizontal slots.
Claim 5
Dependent Claim
46 words
A supporting element according to claim 1, in which said horizontal structural elements extend in the lateral and fore-and-aft directions at the upper and lower ends of said columns whereby the said space between said laterally spaced pairs of columns is unobstructed from top to bottom.
Claim 6
Dependent Claim
26 words
A supporting element according to claim 4, in which said structure is in the form of a portable cart and includes support wheels at the bottom.
Claim 7
Dependent Claim
22 words
A supporting element according to claim 5, which said cart has a horizontal panel secured to the top forming a tabletoplike surface.
Claim 8
Dependent Claim
49 words
A supporting element according to claim 6, which includes clip means secured to at least one edge of said cart at the top and adapted for receiving the edge of a tray and operable to support the tray in a substantially horizontal position adjacent the top of the cart.
Claim 9
Dependent Claim
76 words
A supporting element according to claim 1, in which each offset angular portion includes a horizontal part extending through the respective slot and a vertical part at the end of the horizontal part, said vertical parts extending away from each other, the length Z of each slot in the vertical direction exceeding the vertical length of the lower of said vertical parts but less than the vertical length of the upper one of said vertical parts.
Claim 10
Dependent Claim
97 words
A supporting element according to claim 8, in which each said column flange is formed with a tenon portion extending therealong on the side toward said space and forming a shoulder on the column which defines said recess and which faces the other column of the respective pair of columns, each shoulder being of about the same extent in the horizontal direction as the thickness of said vertical portions of said guide members, each guide member when mounted on its pertaining pair of columns having its support ends closely adjacent to the said shoulders on the columns.
Claim 11
Dependent Claim
29 words
A supporting element according to claim 1, which includes at least two sets of laterally spaced pairs of columns forming at least two of said spaces in side-by-side relation.
Claim 12
Dependent Claim
31 words
A supporting element according to claim 1, in which each said column is in the form of a U-shaped channel opening toward the other column of the respective pairs of columns.
Claim 13
Dependent Claim
57 words
A supporting element according to claim 5, in which each said column is in the form of a U-shaped channel opening toward the other column of the respective pairs of columns, and each said pair of columns on the sides facing the outside of the cart at the sides thereof is adapted for receiving a closure panel.
Claim 14
Dependent Claim
23 words
A supporting element according to claim 1, in which each guide member has a vertically spaced pair of the said leg elements thereon.
Claim 15
Dependent Claim
32 words
A supporting element according to claim 1, in which the said leg element of each guide member is contained so as to conform the contour of the side edge of a tray.
