Abstract
A holder for removably supporting a compact disk. The compact disk is held by its center opening over a post and under a ridge on the outer surface of the post. As the top of the post is pushed downwardly, the outer surface of the post moves inwardly and the ridge compresses and moves downwardly and allows the opening in the compact disk to pass over it. The compact disk is thus easily removed by simply pushing the center of the disk holding post. Preferably, the grooves are spiral shaped.
Claims23
A holder removably supporting a compact disk, said compact disk being of the type having an upper surface, a lower surface, an outer periphery, and a central opening having an inwardly facing circular edge, said holder and disc comprising:
- a compact disk;
- a holder comprising:
- a generally horizontal base including a compact disk contact member;
- a compact disk support post extending upwardly from said horizontal base, said compact disk support post having a vertical central axis, an outer peripheral surface and an inner peripheral surface with a wall therebetween and at least a portion of the outer peripheral surface contacting the inwardly facing circular edge of said compact disk, said support post having a top having an outer edge;
- peripheral protrusions extending outwardly with respect to the outer peripheral surface of said compact disk support post at a location above the inwardly facing circular edge of the central opening of said compact disk, said peripheral protrusions having an upper edge and a lower edge;
- and
- at least three slots formed through said wall of said support post extending upwardly from said horizontal base into said compact disk support post, past said peripheral protrusions and extending into said top, said slots being positioned so that the top has a plurality of continuous paths from the outer edge of the top to an opposite portion of the outer edge of said top and said ridges and said top being configured to permit the downward movement of a central portion of said top whereby when the top is pressed downwardly, at least a portion of the peripheral protrusions moves toward the vertical central axis of said compact disk support post and downwardly and the lower surface of the compact disk contacts said compact disk contact member of said base and at least a portion of the peripheral protrusions passes downwardly through the inwardly facing edge of said compact disk causing the compact disk to pop off the compact disk support post without the necessity of any upwardly directed force.

A holder for removably supporting a compact disk, comprising:
- a horizontal base including a raised, flexible compact disk contact member having an open area underneath said contact member and having an outer portion which resists downward movement and an inner portion that permits downward movement;
- a hollow compact disk support post extending upwardly from said compact disk contact member, said compact disk support post having a vertical central axis, an outer peripheral surface and an inner peripheral surface with a wall therebetween, said support post having a top having an outer edge;
- peripheral protrusions extending outwardly from the outer peripheral surface of said compact disk support post below the outer edge of the top, said peripheral protrusions having an angled upper edge extending outwardly from the support post and a lower edge;
- and
- at least two slots formed through said wall of said support post extending from said contact member upwardly into said compact disk support post, past said peripheral protrusions and extending into said top, said slots being positioned so that the top has a plurality of continuous paths from an edge of the top to an opposite edge of said top and said ridges and said top being configured to permit the downward movement of a contact portion of said top and said raised, flexible compact disk contact member being configured to flex downwardly adjacent said post whereby when the top is pressed downwardly, at least a portion of the peripheral protrusions moves toward the vertical central axis of said compact disk support post and at least a portion thereof moves downwardly below the outer portion of the contact member so that a compact disk supported by said holder will pop off the compact disk support post.

A process for removing a compact disk from a holder, the holder having a center post with a top and an outer edge with protrusions thereon and said compact disk having a central opening with an upper edge below said protrusions and a bottom edge and an inwardly facing edge between the upper and bottom edges of the disk, said process comprising:
- pressing downwardly on the top of the center post an amount sufficient to pass at least a portion of the protrusions through the central opening and past the bottom edge of the opening at least a portion of said protrusions riding along said inwardly facing edge and said at least a portion of said protrusions moving outwardly below said bottom edge;
- releasing the top of the center post to capture the opening of the compact disk at the bottom edge of said central opening by at least a portion of the protrusions;
- and
- removing the resulting loose compact disk from the center post.

A compact disk holder holding a compact disk comprising:
- a compact disk having an upper surface, a lower surface, a central opening with an inner surface having an upper edge and a lower edge;
- a disk holding post having a top surface and a peripheral surface contacting at least a portion of said inner surface of said central opening of said compact disk, said disk holding post having protrusions above the upper surface of said compact disk when said disk holding post is holding a compact disk and said protrusions positioned around at least a portion of said peripheral surface and at least a portion of said protrusions comprising a lift portion having a sloped upper surface;
- at least one slot in said disk holding post passing from above said protrusions to below said protrusions;
- and
- a platform supporting said disk holding post so that the disk holding post will, at least in part, move downwardly when the top surface of the post is pushed downwardly, said platform having an outer disk resisting surface, said post being configured to cause at least a said lift portion of the protrusions to move downwardly and inwardly by contact with the inner surface of the central opening when the top surface of the post is depressed and to move outwardly when the lower edge of said central opening is passed by the downward movement of said lift portion of the protrusions and said compact disk being lifted by the outward movement of said lift portion as downward pushing of the post is released thereby permitting the disk to be easily removed from the holder.
