  • Patent number: 6523685
    Abstract: An improved rosette for securing a disc having a central aperture includes a raised cylindrical hub projecting upward from a planar base, the hub being formed of first and second upstanding annular sections having substantially cylindrical side walls, the first annular section comprising at least 180° of the circumferential extent of the circular hub. Each of the annular sections includes at least one radially extending rim projecting outwardly beyond the cylindrical side walls. An arm cantilevered from the cylindrical wall of the second annular section above the base extends radially inwardly toward the central axis of the hub such that downward finger pressure applied to the free end of the arm causes the cylindrical wall of the second annular section to pivot radially inwardly and downwardly to allow the central aperture of a disc mounted on the rosette to be released from engagment with the radially extending rims for one-handed removal of the disc from the rosette.

  • Patent number: 5896986
    Abstract: An improved rosette for securing at least one disc shaped element having a central aperture includes a raised circular hub having a substantially cylindrical side wall, the hub projecting upward from a planar base; at least one resilient, arcuate, circumferentially extending finger integrally formed with the hub and extending along the perimeter of the hub, each finger being formed integrally with the hub at one end and free at the other end; at least one aperture defined in the base, the number of apertures corresponding to the number of fingers, the fingers being arranged so that the free ends thereof overhang the apertures for permitting the free ends to substantially unobstructedly deflect arcuately inwardly when the disc is inserted on the hub; and a radially extending protrusion on the free end of each finger projecting outwardly beyond the outside diameter of the hub.
