Universal compact disc storage unit
First Claim
1. A retainer assembly for a compact disc having a hole in the center, the assembly comprising:
- a support including a raised area sized to extend beneath portions of the disc around the central hole;
a plurality of circumferentially spaced clamp arms having radially inner, free ends defining a central cylindrical region, said arms having radially outer portions joined to said raised area so that the clamp arms are supported in cantilever fashion, said arms having inner vertically extending portions defining a cylinder having a diameter smaller than the disc central hole, said vertical portions including radially outwardly extending detents defining a circle larger than said hole that retain the disc on the clamp arms, said clamp arms being made of a material that enable the arms to be flexed downwardly so that the detents can be moved inwardly into a position where they no longer retain the disc;
a depressible central release button positioned and retained within said cylindrical region, the button having a shaft region positioned loosely within the cylindrical region; and
a spring positioned below the release button having a central bridge area supporting the button and having a plurality of outer regions supporting the bridge area over a space, the spring having sufficient elasticity so that downward movement of the bridge area will cause upper outer portions of the spring to pivot upwardly, the upper outer portions being positioned in slots between the clamp arms, said retainer assembly having a first position in which said central release button is undepressed, said detents retain the disc on the clamp arms, and said spring is in an unflexed position, said retainer assembly having a second position wherein said central release button has been depressed a first distance, said detents still retain the disc on the clamp arms, and said spring is flexed a predetermined amount to urge said outer portions upwardly against lower surface portions of the disc, and said retainer assembly having a third position wherein said central release button has been depressed a second distance greater than said first distance, and said spring releases its stored energy all at once, causing said spring outer portions to pop said disc above said detents.

Abstract
A system for storing and releasing a compact disc (CD) in storage unit, jewel box or other storage space The system includes a plurality of radially disposed clamp arms cantilevered about a raised area of a structure centrally located within a lower cover of the CD storage unit. CDs are pressed down over the clamp arms, causing detents to firmly hold the CD within the storage unit. A central button is provided for instantly releasing the CD from the insert-release system. The button actuates a crossed spring disposed below the CD. The spring includes outwardly extending legs, within which stresses are developed by pressing down on the central button prior to CD release. The central button eventually contacts the clamp arms to release the CD after stresses within the crossed spring are developed, causing the spring to pop the CD out from the insert-release system. In an alternative embodiment, the insert-release system is formed independently from a storage unit insert tray and is applied directly to the lower cover or to a cardboard liner.

9. A method of retaining and releasing a disc on clamp arms extending through a central opening in the disc comprising:
-
positioning the disc on upwardly extending portions of a plurality of circumferentially spaced clamp arms that extend radially inwardly in cantilever fashion from support structure surrounding the clamp arms; retaining said disc on said portions by detent surfaces extending radially outward on said clamp arms; depressing a release button positioned within a cylindrical area defined by the clamp arms a first distance to depress a central bridge portion of a spring positioned beneath the release button to cause outer upper regions of said spring to pivot upwardly and push against lower surface portions of the disc surrounding its central opening to urge the disc upwardly against said detent surfaces on the clamp arms; and depressing said release button a second distance greater than the first distance to depress said spring bridge portion further and cause a flange on the button to flex the clamp arms inwardly to release the disc from the detent surfaces on the clamp arms to cause the disc to pop upwardly as it is released from said clamp arms.

10. A compact disc storage system for retaining a compact disc having central throughhole comprising:
-
a plurality of circumferentially spaced, inwardly directed clamp arms cantilevered about a peripheral raised area, detents extending outwardly from vertical portions of said clamp arms, the vertical portions defining a cylinder with a diameter approximately equal to a diameter of the central compact disc throughhole so that a compact disc can be pressed onto said clamp arms past said detents to a stored position resting on said raised area; a central release button being positioned and retained within a cylindrical region defined by the clamp arms, the button including a shaft region positioned within the radially inner surfaces of the clamp arms; and a spring positioned below the release button having a central bridge area and a plurality of outer regions supporting the bridge area over a space, the spring having sufficient elasticity so that downward movement of the bridge area will cause the outer regions to pivot upwardly about fulcrums, the outer regions of the spring being positioned in slots in the raised area below a compact disc in the stored position, the detents being of a sufficient size to resist upward motion of the compact disc upon application of a first downward force on the release button, said first downward force sufficient to develop a spring stress within said spring yet insufficient to release said disc from said detents, and wherein a second downward force greater than said first force on the release button is sufficient to force the compact disc upwardly, camming said detents inwardly.
