Pop off nipple snap on fastener for sun shade technology

摘要

The subject invention includes a plurality of projections (46) for sandwiching fabric (42) between inner and outer members (22, 24). Each of the projections (46) extends laterally from the inner member (22) to a distal rim (48) and defines a hollow passageway (50). The outer member (24) defines a plurality of circular holes (58) having a hole diameter (E) for receiving the projections (46) and maintaining the members (22, 24) in a clamping engagement with the fabric (42). The projections (46) define a cylindrical exterior surface (54) extending from the inner member (22) and having an outer diameter (B). A nipple ridge (56) projects radially from the exterior surface (54) of each of the projections (46) to a ridge diameter (A), which is larger than the outer diameter (B) and snaps into a recessed shelf (62) disposed about the holes (58) on the outer member (24) retain the projections (46) in the holes (58).
