Abstract

Abstract A button comprises a button face member; a support plate having a center hole for supporting the face member; a hollow shank having upper and lower open ends, a constricted neck at its upper portion and a shoulder extending downward from the neck, the neck having a smaller diameter than the hole, the shoulder having a larger diameter than the hole; a bending guide member in the form of a ball disposed within the shank and having a spherical surface; an engaging member having a center bore extending therethrough and disposed within the shank under the guide member; and a fastening member having a piercing needle. The support plate is loosely fitted around the neck and prevented from slipping off by an enlarged top portion formed at the upper end of the neck after the support plate has been loosely fitted around the neck. The support plate and the face member fitted over the plate form a button head, which is pivotably turnably supported by the shank. The shank is fastened to a fabric by the piercing needle of the fastening member.
