Patent ID: 7721882

Claim:
A holder for a disk having a central opening and front and back face surfaces, the holder comprising: (a) a base; (b) a pedestal projecting forwardly from the base on a pedestal axis, the pedestal including: (i) a ring structure projecting forwardly from the base for contacting the rear face surface of the disk for supporting the disk axially forwardly relative to the base; (ii) a diaphragm member supported within the ring member in proximate parallel relation to the base and having a relaxed condition being in raised relation to the outside surface portion of the base portion; and (iii) a button structure projecting forwardly from the diaphragm member for engaging the central opening and having retainer members projecting radially outwardly from the central opening proximate the front face surface for releasably holding the disk when the diaphragm member is in the relaxed position, the diaphragm member deflecting axially rearwardly to a depressed position in response to external applied pressure against the button structure with sufficient radially inward and axially rearward movement of the retainer members to permit passage of the retainer members through the central opening of the disk, thereby releasing the disk; (iv) a circumferentially spaced plurality of axially projecting stem members connecting the retainer members to the diaphragm member; (v) a plurality of column members forwardly projecting from the diaphragm member and circumferentially spaced between the stem members, and a button member connecting the column members for receiving the applied pressure against the button structure; and (vi) a segment member projecting downwardly from the button member for limiting downward travel of the button member when the holder is resting on a supporting surface.
