Abstract
Abstract The present invention relates to improvements in turntable or rotatable display devices on which a great variety of wares, merchandise and the like may be accommodated for sale, display, distribution, etc. The device principally consists of a tubular aluminum and like extrusion element, which is rotatably connected to a central supporting post via a thrust bearing and the like and may be turned about said post to assume different locations relative to said post. This extruded body or element is of a special profile in cross-section and is employed to support a plurality of lengthy partitions, between which display sections are created, in which through suitable connection between each tray or shelf and said extruded element the partitions are maintained in position and stabilized during their operation and in their assembly, although said partitions may be manufactured from relatively thin sheet metal, e.g., aluminum, steel and the like or even from plastic material. The crux of the invention is to couple and anchor the partitions as well as the display trays on a single central tubular body which is profiled in crosssection to facilitate anchorage of all the vital parts of the new display device onto a central and tubular column constituting the extruded body.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
154 words
In a rotary display device having a central support for maintaining a lengthy column in rotatable position thereon; said column being made of extruded material and having a perimeter profiled in cross-section, partition means, tray means each provided with a projection a plurality of radially, inwardly extending first elements in said column and forming elongated grooves which are open at the perimeter and substantially parallel to the axis of said column, a plurality of radially, inwardly extending second elements in said column and forming elongated channels, said channels being open along said perimeter and being located intermediate said grooves, each of which latter is structured to receive and support therein a corresponding part of a respective partition means, said elongated channels being shaped in profile to rotatably and slidably receive correspondingly formed projection provided on each of said tray means for coupling the latter with said channels and for location between two partition means.
Claim 2
Dependent Claim
154 words
In a rotary display device having a central support for maintaining a lengthy column in rotatable position thereon; said column being made of extruded material and having a perimeter profiled in cross-section, partition means, tray means each provided with a projection a plurality of radially, inwardly extending first elements in said column and forming elongated grooves which are open at the perimeter and substantially parallel to the axis of said column, a plurality of radially, inwardly extending second elements in said column and forming elongated channels, said channels being open along said perimeter and being located intermediate said grooves, each of which latter is structured to receive and support therein a corresponding part of a respective partition means, said elongated channels being shaped in profile to rotatably and slidably receive correspondingly formed projection provided on each of said tray means for coupling the latter with said channels and for location between two partition means.
Claim 3
Dependent Claim
37 words
In a device according to claim 1, including interengageable means structured to extend between each of said partitions and corresponding adjacent parts of said tray means for anchoring said tray means in predetermined position to adjacent partitions.
Claim 4
Dependent Claim
47 words
In a device according to claim 1, including cover plate means applicable to the top end of said column, and means forming part of each partition to retain the latter in position in the respective groove at the top end of the latter near said cover means.
Claim 5
Dependent Claim
27 words
In a display device according to claim 3, said cover means being provided with slotted openings which are of greater dimension than that of the lengthy grooves.
Claim 6
Dependent Claim
64 words
In a device according to claim 1, wherein said column is made of extruded metal material and in which said grooves and said channels making up said profile of said column in cross-section radially extend toward the central axis of said column and present at the oUter surface of the latter openings for the insertion of said partitions and said projections of said trays.
Claim 7
Dependent Claim
66 words
In a device according to claim 3, said cover means having further slotted openings conformed in shape and dimension substantially corresponding to those of said elongated channels, so that projections of said tray means may be readily fitted and engaged in said channels for position relatively to said column, said channels and said grooves being respectively in registry with the slotted openings of said cover means.
Claim 8
Dependent Claim
133 words
A rotary display device having a central support, comprising an elongated extruded hollow body connected to said support for relative rotation thereabout, the periphery of said body being provided with two types of profiled engageable means radially extending toward the axis of said body and spaced from each other, all said profiled means opening at the periphery of said body, partition means, and tray means, each tray means including a forward end and a rearward end and lateral end faces between said ends, said partition means being structured and positionable to engage one type of said profiled means, said rearward end of each tray means being structured for slidable engagement with and positionable in another type of said profiled means and with said lateral end faces for location between two adjacent partition means.
Claim 9
Dependent Claim
133 words
A rotary display device having a central support, comprising an elongated extruded hollow body connected to said support for relative rotation thereabout, the periphery of said body being provided with two types of profiled engageable means radially extending toward the axis of said body and spaced from each other, all said profiled means opening at the periphery of said body, partition means, and tray means, each tray means including a forward end and a rearward end and lateral end faces between said ends, said partition means being structured and positionable to engage one type of said profiled means, said rearward end of each tray means being structured for slidable engagement with and positionable in another type of said profiled means and with said lateral end faces for location between two adjacent partition means.
Claim 10
Dependent Claim
183 words
A rotary device having a central support comprising an extruded body operatively connected to said support and for relative rotation thereto, said body having a perimetrical surface provided with a plurality of inwardly and radially extending integral mounting means profiled in cross-section, said mounting means being spaced from each other and opening lengthwise of said surface and in substantially axial direction of said body, partition means, tray means, each of said partition means being positionable for anchorage in respective mounting means, the space between adjacent partition means being shaped for the location of said tray means, each tray means having a frontal end and a rearward end, the rearward end of each tray means being structured to rotatably interengage with respective other of said mounting means, said tray means being shaped for location in the sectional space between two adjacent partition means when interengaged with other of said mounting means, and respective coupling means on said tray means and on said partition means to facilitate connection devoid of any fastening medium between said tray means and partition means for anchorage on the latter.
