Abstract
Abstract A card holding device has arcuate slide means enabling an open card holding body element to slide back and forth arcuately on a base element to facilitate reference to the cards. The slide means comprise intimately opposed, cylindrical, upwardly arcing, slideably coacting surfaces of substantial length and of relatively large radii, enabling the body element both to tilt and to be bodily displaced forwardly and rearwardly.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
140 words
A card holding device comprising a body element provided with an upwardly facing card supporting surface of a length substantially corresponding to the combined thicknesses of a plurality of cards to be supported by said element, a base element upon which said body element rests, and slide means enabling said body element to slide back and forth arcuately upon said base element about a horizontal axis located below said slide means and extending transversely of the direction of sliding movement of said body element; said slide means comprising intimately opposed, partially cylindrical, relatively slideable surfaces of said body and base elements, and the lengths of said slideable surfaces being less than one fourth the circumference of a cylinder of the same curvature as said slideable surfaces and equal to a major part of the length of said card supporting surface.
Claim 2
Dependent Claim
140 words
A card holding device comprising a body element provided with an upwardly facing card supporting surface of a length substantially corresponding to the combined thicknesses of a plurality of cards to be supported by said element, a base element upon which said body element rests, and slide means enabling said body element to slide back and forth arcuately upon said base element about a horizontal axis located below said slide means and extending transversely of the direction of sliding movement of said body element; said slide means comprising intimately opposed, partially cylindrical, relatively slideable surfaces of said body and base elements, and the lengths of said slideable surfaces being less than one fourth the circumference of a cylinder of the same curvature as said slideable surfaces and equal to a major part of the length of said card supporting surface.
Claim 3
Dependent Claim
22 words
A card holding device according to claim 1, said card supporting surface being arcuate and approximately parallel to said relatively slideable surfaces.
Claim 4
Dependent Claim
28 words
A card holding device according to claim 2, said body element including card supporting wings integral with and projecting upwardly from opposite ends of said card supporting surface.
Claim 5
Dependent Claim
66 words
A card holding device according to claim 1, said body element being formed with a downwardly opening cavity of which an upper area is defined by one of said relatively slideable surfaces, said base element having an upper portion with the other of said slideable surfaces at the top thereof, and said base element complementally extending into said cavity with said slideable surfaces in slideable interrelationship.
Claim 6
Dependent Claim
22 words
A card holding device according to claim 1, further including stop means for limiting relative rocking and sliding movement of said elements.
Claim 7
Dependent Claim
49 words
A card holding device according to claim 1, one of said slideable surfaces being formed with an arcuately extending slot therein, and the other of said sliding surfaces having a stop element fixed thereto and extending within said slot to limit relative rocking and sliding movement of said elements.
Claim 8
Dependent Claim
15 words
A card holding device according to claim 6, said stop element comprising a resilient ring.
Claim 9
Dependent Claim
26 words
A card holding device according to claim 1, further including cushioning means interposed between said relatively slideable surfaces and fixed to one of the latter surfaces.
Claim 10
Dependent Claim
26 words
A card holding device according to claim 8, said cushioning means comprising strips of cushioning sheet material extending forwardly and rearwardly of said relatively slideable surfaces.
