Abstract

Abstract Holder for a disc-like object having a diameter which can vary within a predetermined range and having generally planar first and second spaced parallel surfaces and a circular edge extending at right angles to said generally planar surfaces of said object. The holder comprising a member having substantially planar first and second spaced parallel surfaces with said member having a generally circular hole therein extending through both of said surfaces for receiving one of said disc-like objects. The hole has a size so as to be able to accommodate an object of the largest diameter. The member is formed with at least three object-retaining portions extending into the hole which are adapted to be engaged by the edge of the object disposed in the hole to retain the object in said hole in said member. The member is formed of material whereby the portions can be deformed by said object as it is inserted to accommodate objects of varying diameters while retaining the object within the hole in the member.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 210 words
In a holder for a disc-like object of the type having a diameter which can vary within a predetermined range and having generally planar first and second spaced parallel surfaces and a circular edge extending at right angles to said first and second planar surfaces of said object, a solid single unitary sheet-like member having substantially planar first and second spaced parallel surfaces, said member having a generally circular hole therein extending through both of said surfaces for receiving the object, the portions of said first and second surfaces surrounding said circular hole being continuous, said member being formed with at least three object-retaining portions integral with said member extending into said hole and being of substantially the same vertical extent as said hole, said member being adapted to be engaged by the edge of one of said objects disposed in said hole to retain said object in said hole, said member being formed of a material whereby said portions can be deformed permanently by said object as it is inserted to accommodate the object while retaining the object within the hole in the member, said object retaining portions being formed with inclined chamfered surfaces on one side of the same to facilitate insertion of the object into the hole.
Claim 2
Dependent Claim 210 words
In a holder for a disc-like object of the type having a diameter which can vary within a predetermined range and having generally planar first and second spaced parallel surfaces and a circular edge extending at right angles to said first and second planar surfaces of said object, a solid single unitary sheet-like member having substantially planar first and second spaced parallel surfaces, said member having a generally circular hole therein extending through both of said surfaces for receiving the object, the portions of said first and second surfaces surrounding said circular hole being continuous, said member being formed with at least three object-retaining portions integral with said member extending into said hole and being of substantially the same vertical extent as said hole, said member being adapted to be engaged by the edge of one of said objects disposed in said hole to retain said object in said hole, said member being formed of a material whereby said portions can be deformed permanently by said object as it is inserted to accommodate the object while retaining the object within the hole in the member, said object retaining portions being formed with inclined chamfered surfaces on one side of the same to facilitate insertion of the object into the hole.
Claim 3
Dependent Claim 22 words
A holder as in claim 1 wherein said member is formed of plastic ranging from 2,000 to 5,000 psi in tensile strength.
Claim 4
Dependent Claim 27 words
A holder as in claim 1 wherein each of said portions is provided with inclined side walls which adjoin the wall defining the hole in said member.
Claim 5
Dependent Claim 15 words
A holder as in claim 1 wherein at least five of said portions are provided.
Claim 6
Dependent Claim 14 words
A holder as in claim 4 wherein said portions are spaced approximately 72* apart.
Claim 7
Dependent Claim 18 words
A holder as in claim 1 together with first and second parts bonded together to enclose said Member.
Claim 8
Dependent Claim 33 words
A holder as in claim 1 wherein said first and second walls of said member are spaced apart a greater distance than the spacing between the first and second surfaces of said object.
