Abstract: Provided is a button attachment tool that can eliminate or reduce rotation of a cap relative to an attachment tool body. A button attachment tool comprises a metal attachment tool body and a synthetic resin cap to which the attachment tool body is coupled. The attachment tool body includes a cylindrical part and a flange part extending radially outward from one axial end of the cylindrical part. The flange part includes a plurality of notches recessed radially inward from a peripheral edge of the flange part. The cap includes a clamping part that is fastened to a radially outer portion of the flange part including the plurality of notches.

Abstract: Snap fasteners are attached to a fabric or substrate and resist water migration from one side of the fabric or substrate to an opposite side of the fabric or substrate. The water migration resistant snap fasteners resist water migration through the fabric to which the snap fastener is attached while maintaining secure attachment to the fabric. The water migration resistant snap fasteners have radially offset patterned circles of gripping protrusions which do not penetrate through the fabric. Also, the radial patterned circles of gripping protrusions securely grip the fabric and maintain the snap fasteners in the proper location on the fabric.

Abstract: The present invention provides a sandwich button including: (1) a collet having a generally cylindrically shaped stem having at a first end a first annular flange extending about a peripheral portion of the first end and extending axially away therefrom; (2) a back member having opposed first and second surfaces, a first attaching member, and a centrally disposed through hole, the first surface of the back member abuts a surface of the first annular flange, an annular lip extends circumferentially about the through hole and axially away from the second surface of the back member, a portion of the lip forms an interference fit with a portion of the stem and defines an interference zone having a non-circular cross-sectional shape, the interference fit prevents relative rotational movement of the back member and the collet; and (3) a shell member having a second attaching member extending axially away from a first surface of the shell member, the second attaching member fixedly engaging the first attaching membe

Abstract: A self draining snap fastener socket allows water and other liquids to drain from inside of the self draining snap fastener socket. The self draining snap fastener socket has a snap action attachment/detachment portion defining a channel for a resilient snap member. The channel has an annular side wall extending generally along an axial direction of the self draining snap fastener socket, an upper flange extending from an upper portion of the annular side wall toward a socket center, and a lower flange extending from a lower portion of the annular side wall toward the socket center. A fluid passageway extends from the interior of the self draining snap fastener socket through the annular side wall to outside of the self draining snap fastener socket.

Abstract: The present invention provides one-way safety locking buckles. The one-way safety locking buckle has a buckle portion and a snap fastener socket. A strap can be adjustably inserted into the buckle portion. The one-way safety locking buckle can be removably connected to a snap fastener stud by snap-fitting the snap fastener socket onto the snap fastener stud. The snap-fastener socket has an unsnap lock which prevents removal of the snap-fastener socket and the buckle from the snap-fastener stud in certain directions. The unsnap lock allows the one-way safety locking buckle to be removed from the snap-fastener stud in a particular direction.

Abstract: An instrument for measuring the pluck resistance of snap-members has a presser for pressing the fabric of a garment to which a snap member is attached, securely around the member and a plurality of jaws for constraining the sides of the snap member. A tensile force pulls the snap member away in the direction at right angles to the fabric surface to which the snap member is attached and a gauge measures the tensile force.
