  • Publication number: 20040112773
    Abstract: A disc storage case includes a base, a clamp having disc-retaining fingers that pass through an aperture in a disc to retain the disc parallel to the base, and a number of suspension arms radiating from the clamp and extending in off-radial directions to the base. The arms, in combination, take on a vortex-form. As a result, the length of each arm is maximised to provide a soft suspension for the clamp wherein radial movement of the disc-retaining fingers is achieved with little vertical force applied to the disc itself.

  • Patent number: 6547068
    Abstract: The present invention relates to a storage case having a central retaining element which comprises a push-button, at least two spring-catches forming a locking element, and at least two supporting clips forming a supporting element. Each spring-catch has a first projecting portion with a projection and a spring-arm and each supporting clip has a second projecting portion and a supporting plate. The spring-arms and the supporting plates are tilted down to form a conical seat. The spring-catches and the supporting clips are spaced by means of the spacing slits. The push-button is placed in the central hole defined by spring-catches and integrated with the underside of spring-catches. When a pressure applied on the push-button is released, the projection will make its outside tilted surfaces to lift the disc from the supporting surface. As such, the user can readily remove the CD.
