ABSTRACT:
A novel grommet with improved fabric-engaging retaining means. Said grommet includes a pair of like annular washers arranged at opposite surfaces of the fabric structure, about an opening therein; and a central coupling sleeve engaged through said opening and the washers and having outwardly formed washer-engaging end portions. The washers have axially inwardly disposed fabric-engaging inner surfaces defined by portions of the washers established of plastic material and have flat annular metal portions spaced axially outward from said inner surfaces. The washers next include elongate axially inwardly projecting axially inwardly convergent fabric and plastic penetrating conical projections carried by said metal portions and projecting through and inwardly from said plastic portions. The conical projections on each washer project through the fabric structure, penetrate the plastic portion of the other washer and engage the metal portion thereof. The projections on each washer are spaced circumferentially and radially throughout the major radial and circumferential extent thereof and are offset from and occur between the projections on the other washer.
