Button assembly.

摘要

A button assembly (20) includes a hollow button body (21) having a garment-engaging base portion (26) through which a shank (36) of an eyelet (22) is inserted into the button body (21) for being staked on the base portion (26) to join the button body (21) with the eyelet (22). The base portion (26) includes a plurality of retaining ribs (34) projecting into the interior of the button body (21) for retaining thereon an annular curled edge (39) of the shank (39) when the eyelet (22) is axially compressed. The ribs (34) stiffen the base portion (26) and increase the effective thickness of the base portion (26) with the result that the shank (36) can be joined with the button body (21) by a relatively small rivetting force because the end portion of the shank (36) to be deformed becomes short. With the interiorly projecting ribs (34), the base portion (26) has a planar outer surface (26a) engageable flatwise against a garment fabric (23) so that the button assembly (20) can be attached neatly onto the garment fabric (23) without any damage or wrinkles on the garment fabric (23) around the button assembly (20).
