Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
239 words
A one-piece button for cooperative engagement with fastening means in upholstery work, said button including a head and a tapered substantially rigid stem projecting from said head and terminating in a reversely bent hook means extending back toward said head to provide a bight portion facing said head, said hook portion terminating in a beveled surface which slants in the direction of said bight portion, a locking finger having a predetermined resilient hinge point extending angularly away from said head toward said bight and having its free end positioned below the upper extremity of said hook portion in spaced opposed relation to said beveled surface to form a throat having a limited predetermined opening size, the free end of said locking finger being beveled toward said beveled surface of said hook, said beveled surfaces of said hook and said finger lying in planes which are generally perpendicular to each other, said locking finger having means to limit the opening size of said throat, whereby introduction of said cooperative fastening means into said throat results in movement of said finger in one direction about said hinge point to increase said throat size for acceptance of fastening means into said bight while movement of fastening means in the opposite direction will close said throat by contact of the fastening means with the beveled free end of said finger and its resultant movement into contact with said beveled surface of said hook.
