Abstract
Abstract A display system for the interchangeable presentation of art prints or other substantially flat display objects, and for the storage of a number of such prints not being displayed. Magnets are disposed within recesses in a background member or plaque and these magnets engage metallic plates or foil elements permanently affixed to the back of a picture to be displayed for secure mounting thereof to the plaque in a predetermined orientation. A mat may be provided surrounding the displayed picture and it may also be maintained in position by magnetic means.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
128 words
A display device comprising: a background member having a display surface and a back surface; a non-rigid two-dimensional display object; a plurality of thin metallic keeper plates affixed in spaced relationship to the back surface of said display object; a like plurality of magnets embedded in said display surface in a spaced configuration substantially the same as the arrangement of keeper plates on said display object; and side members extending rearwardly from said background member to form, with said back surface, an open rearwardly facing box-like cavity of substantially the same lateral dimensions as said display object adapted for flat storage of additional display objects; whereby said display object is removably retained on said display surface by means of mutual engagement between said magnets and said keeper plates.
Claim 2
Dependent Claim
128 words
A display device comprising: a background member having a display surface and a back surface; a non-rigid two-dimensional display object; a plurality of thin metallic keeper plates affixed in spaced relationship to the back surface of said display object; a like plurality of magnets embedded in said display surface in a spaced configuration substantially the same as the arrangement of keeper plates on said display object; and side members extending rearwardly from said background member to form, with said back surface, an open rearwardly facing box-like cavity of substantially the same lateral dimensions as said display object adapted for flat storage of additional display objects; whereby said display object is removably retained on said display surface by means of mutual engagement between said magnets and said keeper plates.
Claim 3
Dependent Claim
37 words
The display device recited in claim 1 and further comprising: elongated elastic bands secured in a grid arrangement to said back surface of said background member; whereby additional display objects may be stored in said box-like cavity.
Claim 4
Dependent Claim
37 words
The display device recited in claim 1 wherein at least one of said side members is formed with a rearwardly opening indentation to accept a hanging element projecting from a wall to hang said display device thereon.
Claim 5
Dependent Claim
20 words
The display device recited in claim 1 wherein the front surfaces of said magnets are flush with said display surface.
Claim 6
Dependent Claim
35 words
The display device recited in claim 1 wherein said display surface is recessed in said background member to form a well within which said magnets are located and within which said display object is confined.
Claim 7
Dependent Claim
41 words
The display device recited in claim 5 wherein said background member is formed with holes therethrough adjacent and spaced inwardly from said magnets to permit said display object to be pushed away from said display surface for interchanging said display object.
Claim 8
Dependent Claim
139 words
A display device for the interchangeable presentation of non-rigid two-dimensional display objects comprising: a background member having a display surface and a back surface; a plurality of thin metallic keeper plates affixed in spaced relationship to the back surface of said display object; a like plurality of magnets embedded in said display surface in a spaced configuration substantially the same as the arrangement of keeper plates on said display object; side members extending rearwardly from said background member to form, with said back surface, a rearwardly facing box-like cavity; and elongated elastic bands secured in a grid arrangement to said back surface of said background member, whereby additional display objects may be stored in said box-like cavity; said display object being movably retained on said display surface by means of mutual engagement between said magnets and said keeper plates.
Claim 9
Dependent Claim
139 words
A display device for the interchangeable presentation of non-rigid two-dimensional display objects comprising: a background member having a display surface and a back surface; a plurality of thin metallic keeper plates affixed in spaced relationship to the back surface of said display object; a like plurality of magnets embedded in said display surface in a spaced configuration substantially the same as the arrangement of keeper plates on said display object; side members extending rearwardly from said background member to form, with said back surface, a rearwardly facing box-like cavity; and elongated elastic bands secured in a grid arrangement to said back surface of said background member, whereby additional display objects may be stored in said box-like cavity; said display object being movably retained on said display surface by means of mutual engagement between said magnets and said keeper plates.
Claim 10
Dependent Claim
35 words
The display device recited in claim 7 wherein said display surface is recessed in said background member to form a well within which said magnets are located and within which said display object is confined.
Claim 11
Dependent Claim
20 words
The display device recited in claim 8 wherein the front surfaces of said magnets are flush with said display surface.
Claim 12
Dependent Claim
123 words
The display device recited in claim 7 and further comprising: a mat having external dimensions greater than the external dimensions of said display object and an internal opening smaller than said display object, said internal opening being larger than the area defined by said configuration of magnets; a plurality of thin metallic keeper plates affixed in spaced relationship to the back surface of said mat; and a like plurality of magnets embedded in said display surface in a space relationship substantially the same as the arrangement of keeper plates on said mat; whereby said mat is removably retained on said display surface by means of mutual engagement between said magnets and said keeper plates, said mat providing a border around said display object.
Claim 13
Dependent Claim
29 words
The display device recited in claim 9 and further comprising metallic plates secured by magnetic attraction to the back surface of each of said magnets within said background member.
