Abstract
A button for receiving and holding a fabric covering which includes a base element having a main body with a convex-shaped exterior surface, a flat underside and a tapered central opening and a cap member to be outwardly covered by a fabric piece and having a concave interior surface for receiving the main body and engaging therebetween the edge of the exterior fabric covering, a central tapered projection for insertion in the tapered opening, and an annular lip for extending along the underside to retain the base element in the cap member. The tapered projection is larger than the tapered opening and the main body is scored along a radial line extending outwardly from the opening for radial expansion, thereby facilitating radial expansion of the main body as the projection is inserted into the opening to greater depths to engage the fabric edge. Thus, the button adapts readily to fabric coverings of varying thicknesses by varying the amount of radial expansion of the main body. In one form, an interior lip of the cap member engages in a recess of the base element to aid in retaining it in the cap member. In another form, the base element has annular ridges and the cap member has annular grooves which engage the fabric edge and each other to aid in retaining it in the cap member.
