Abstract
Abstract An improved display device for organizing, storing and displaying a series of collectibles (for example, autographed baseballs) or the like comprising a series of stacked shelves wherein each shelf is made up of a series of circular disc elements that reversibly engage and disengage to adjacent center shelf elements and/or end shelf elements such that the entire display device pivots about the center axis of the stack of disc elements. In this manner, a structurally stable display device that can be configured in a variety of positions and can be expanded as the number of items being displayed increase is produced.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
167 words
A display device comprising: (a) a plurality of circular disc means for engaging adjacent center shelf means and end shelf means such that the assembly forms a display shelf; (b) a plurality of center shelf means slidably engaging adjacent circular disc means such as to pivot about the center of said adjacent circular disc means; (c) a plurality of end shelf means slidably engaging adjacent circular disc means such as to pivot about the center of said adjacent circular disc means; and (d) a plurality of vertical structural means engaging the top of a first assembly of circular disc means, center shelf means and end shelf means forming a lower display shelf and engaging the bottom of a second assembly of circular disc means, center shelf means, and end shelf means forming an upper display shelf thus supporting the second upper display shelf, whereby the display shelves may be pivoted about said center shelf means so that the display device can be adjusted to form various arrangements.
Claim 2
Dependent Claim
167 words
A display device comprising: (a) a plurality of circular disc means for engaging adjacent center shelf means and end shelf means such that the assembly forms a display shelf; (b) a plurality of center shelf means slidably engaging adjacent circular disc means such as to pivot about the center of said adjacent circular disc means; (c) a plurality of end shelf means slidably engaging adjacent circular disc means such as to pivot about the center of said adjacent circular disc means; and (d) a plurality of vertical structural means engaging the top of a first assembly of circular disc means, center shelf means and end shelf means forming a lower display shelf and engaging the bottom of a second assembly of circular disc means, center shelf means, and end shelf means forming an upper display shelf thus supporting the second upper display shelf, whereby the display shelves may be pivoted about said center shelf means so that the display device can be adjusted to form various arrangements.
Claim 3
Dependent Claim
43 words
A display device of claim 1 wherein said circular disc means engages to said adjacent center shelf means or said end shelf means by inserting into a groove in a semi-circular edge of said adjacent center shelf means or said end shelf means.
Claim 4
Dependent Claim
43 words
A display device of claim 1 wherein said circular disc means engages to said adjacent center shelf means or said end shelf means by inserting into a groove in a semi-circular edge of said adjacent center shelf means or said end shelf means.
Claim 5
Dependent Claim
53 words
A display device of claim 3 wherein the semi-circular edge and groove of said center shelf means and of said end shelf means span a circular arc of about 150° thus allowing the display device to bend through an angle up to about 30 ° at each vertical stack of circular disc means.
Claim 6
Dependent Claim
178 words
A display device comprising: (a) a plurality of circular disc means for engaging adjacent center shelf means and end shelf means such that the assembly forms a display shelf; (b) a plurality of center shelf means slidably engaging adjacent circular disc means such as pivot about the center of said adjacent circular disc means; (c) a plurality of end shelf means slidably engaging adjacent circular disc means such as to be adapted to pivot about the center of said adjacent circular disc means; and (d) a plurality of vertical structural means engaging the top of a first assembly of circular disc means, center shelf means and end shelf means forming a lower display shelf and engaging the bottom of a second assembly of circular disc means, center shelf means, and end shelf means forming an upper display shelf thus supporting the second upper display shelf above the lower display shelf as successive display shelves whereby the display shelves may be pivoted about said center shelf means so that the display device can be adjusted to form various arrangements.
Claim 7
Dependent Claim
178 words
A display device comprising: (a) a plurality of circular disc means for engaging adjacent center shelf means and end shelf means such that the assembly forms a display shelf; (b) a plurality of center shelf means slidably engaging adjacent circular disc means such as pivot about the center of said adjacent circular disc means; (c) a plurality of end shelf means slidably engaging adjacent circular disc means such as to be adapted to pivot about the center of said adjacent circular disc means; and (d) a plurality of vertical structural means engaging the top of a first assembly of circular disc means, center shelf means and end shelf means forming a lower display shelf and engaging the bottom of a second assembly of circular disc means, center shelf means, and end shelf means forming an upper display shelf thus supporting the second upper display shelf above the lower display shelf as successive display shelves whereby the display shelves may be pivoted about said center shelf means so that the display device can be adjusted to form various arrangements.
