Abstract:
A holder for a disk having a central opening and front and back face surfaces, a data region extending inwardly from proximate an outer perimeter of the disk to a diameter of approximately twice that of the central opening, the holder comprising:(a) a base having a panel portion;(b) a pedestal projecting forwardly from the panel portion on a pedestal axis, the pedestal including:(i) a central button portion having a plurality of axially extending stem members;(ii) a plurality of arm members supporting the retainer members and the stem members of the button portion in cantilevered relation to the base, the arm members collectively having a relaxed position, an engaged position for retaining the disk by engagement of the front face surface by the retainer members proximate the central opening, and a depressed position wherein free end extremities of the arm members are deflected axially rearwardly from the relaxed position in response to applied pressure against the button portion with sufficient radially inward and axially rearward movement of the retainer members and the stem members to permit passage of the retainer members and the stem members through the central opening of the disk; and(iii) a ring structure projecting forwardly from the base and having a plurality of circumferentially extending spring portions, each of the spring portions comprising a deflectable arch member, opposite ends thereof being supported relative to the base for biasingly contacting the rear face surface of the disk between the central opening and the data region for urging the disk axially forwardly relative to the retainer portions when the retainer members are engaging the front face surface of the disk and the arm members are moved toward the depressed position, whereby the disk is moved axially forwardly by the spring portions as the arm members reach the depressed position.
