Abstract: The present invention is directed to an improved fastening apparatus comprising a coil pin having a coil shape and a threaded pin receiver, said pin and fastener being releasably connectable by threading them together so that the coil and threads mesh. The coil pin may have a pointed end for penetrating fabric material of a duvet and duvet cover so that the fastening apparatus may secure the duvet and duvet cover together.

Abstract: A detachable button system has a fixed base component permanently attached to a garment and a detachable button component. The base and the detachable button components each have cooperating attachment elements that allow the components when assembled to function as a button. The button component may be easily detached by the user, and replaced with a different button component. The attachment elements may be a mateable combination of a slotted abutment cylinder and cooperating pin catch, a mateable combination of a threaded cylinder and threaded pin, or the like. The base component may have a disc or shank which can be sewn or otherwise attached to the garment.

Abstract: Various cufflink embodiments are provided. In some embodiments, the cufflink has opposed first and second heads that are releasably locked relative to each other. In some embodiments, the opposed first and second heads can be locked releasably in multiple positions with respect to each another. In other embodiments, a stud or cufflink includes a removable decorative insert. In certain embodiments, a cufflink includes a retention structure configured to temporarily retain part of the cufflink on a shirt cuff. Some embodiments provide a cufflink having an actuator protected against inadvertent actuation.

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: A fastener system mounts a pouch onto a shirt or other clothing article, wherein the pouch provides a receptacle aperture into which a fastener is placed with its flanges positioned on opposing sides of the aperture. The cloth to which the fastener is mounted is gripped between the fastener and the aperture and is locked into place by a U-shaped clip. The flanges are made oblong in shape so that the narrow orientation of the flanges easily pass through the aperture, but the longer orientation cannot. Flats may be applied to both aperture and the fastener so as to assure an orientation in use wherein the fastener cannot disengage from the pouch.

Abstract: A self-fastening and replaceable button for a fabric that includes a first portion, and a second portion. The first portion includes a retainer, and a first projection that extends from the retainer and is a hollow coil that is helically-shaped so as to form a thread pattern that pierces and threads through the fabric. The second portion includes a fastener that is button-shaped, and a second projection that depends from the fastener and engages with the first projection. In a first embodiment, the retainer is disk-shaped, and the second projection is cylindrically-shaped and has a socket that threadably receives the first projection. In a second embodiment, the retainer is the proximal end of the first projection enlarged. In a third embodiment, the second projection is another hollow coil that is helically-shaped so as to form a thread pattern that threadably engages with the first projection.

Abstract: A fastener system which can be utilized with leather type fabric, such as shoes for attaching decorative pieces which consists of a flat disk shaped member which has a protruding component which interlocks with another flat disk shaped component which has a receiving component. The tolerances allow the two disk shape components to be affixed together such that they hold an ornamental piece in a certain position. The two disks sit parallel with each other or can be dimensioned to allow one to sit into the other such that on one side the two pieces create a relatively flat surface in relationship to the surface of the fabric. These configurations permit the ornament to be attached to the clothing without the feel of a lump or projection to the person wearing the article. This result is highly desirable, for example, at the instep of shoes where ornaments are often attached and the body is sensitive to any lump or projection.

Abstract: A fastening device for securely and reliably joining parts of clothing, such as shirt collars, shirt cuffs, or the like. The fastening device is adapted to be inserted through a sturdy and preformed opening in the clothing, such as a buttonhole. The device incorporates a sturdy base member having a stem and a bar-like clothing engaging head which is biased by springs. The head pivots so as to grip the clothing parts to be joined, while the springs firmly position the head in a parallel orientation to the base member, with the parts of clothing to be joined captured therebetween. The springs also provide automatic pivoting of the head so that the device can be conveniently and easily used one-handedly. The device may be ornamentally decorated with distinctive and visually appealing insignia.

Abstract: A split ring spring for snap fasteners has a burr extending from each end of the ring spring in a direction parallel to the imaginary central axis of the ring spring. When a stud member is snapped with a socket member in which the split ring spring is incorporated, the burrs do not damage or scar a body of the stud member. The ring spring having such unobjectionable burrs is produced by feeding a length of a strip of resilient material transversely across a mandrel, then severing the length off the strip in a direction parallel to the longitudinal axis of the mandrel while holding the length on the mandrel, and thereafter bending the severed length of strip around the mandrel.

Abstract: Snap fastener uses a grommet attached to a first layer of fabric and defining a passage. A unitary button and shank as designed to have the shank attach to the grommet with a snap action and on its free end to attach to a second layer of fabric.

Abstract: A covered button comprises a button body consisting of a mushroomlike head and a shank, a covering material covering the head and a washer adapted to retain the peripheral edge of the covering material in position on the back of the head. The inner periphery of the washer bites into the shank to prevent it from dislodging.

Abstract: Apparatus for mounting a printed circuit board to a conductive surface in a manner to allow removal of the board from the surface without requiring the use of any tools. The mounting is performed by an insulating layer covering the printed circuit board interposed between the board and the conductive surface. The insulation exhibits high temperature stability. Preferably the mounting uses hook and pile strips of nylon with one strip adhered to and covering the entire board and one or more mating strips adhered to the conductive surface.
