Abstract:
In a case for storing a digital media laser disk having upper and lower faces and an inner edge defining a central circular opening, the case including a floor positioned within a frame, the improvement comprising a raised seat on a central location on the floor, said seat adapted for releasably engaging the inner edge of the circular opening of the disk, the improvement comprising:(a) an outer cylindrical rim connected to the floor and including an inner and an outer sidewall, said outer sidewall having a diameter between two and two and one half times the diameter of the central opening of the disk;(b) a centrally located cylindrical button positioned above the horizontal plane of said rim and including a sidewall having upper and lower edges, and an upper face having an outer edge connected to said upper edge, said button movable toward the floor in response to downward pressure on said face for releasing the disk from the seat;(c) a plurality of flexible planar branches extending radially outwardly and slanting downwardly away from said button for being raised and lowered between two angles responsive to downward pressure on the face of the button, each of said branches including an upper horizontal surface connected by a hinge to said lower edge of the sidewall of the button and a lower horizontal surface connected to said inner sidewall of said rim;(d) a vertical face having first and second ends interconnecting said upper and lower horizontal surfaces, respectively, and including a wedge-shaped notch thereon for engaging the inner edge of the opening of the disk in the absence of downward pressure on the face of the button, and releasing the inner edge in the presence of downward pressure on the face of the button; and(e) a plurality of trapezoidally-shaped planar arms positioned in alternating sequence with said branches, each of said arms including a first end connected to the inner sidewall of said rim and a second free end extending inwardly toward the button for supporting the lower face of the disk.
