Rosette with release tab for holding disc shaped elements

摘要

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.
