In one modification of the invention, the oblique portion of the surface cross section starts prior to the plane of the short straight line portion of the cross section and crosses it prior to merging with the connecting portion of the cross section.

Abstract: A fastener comprising a male member formed of a flat base, a clipping shank provided on the underside of the base, and a pillar erected upright from the upper side of the base and provided at the leading end thereof with a head, and a female member formed of a tubular part, a pair of depressing blades raised through thin-walled hinges from the tubular part and projected parts provided at the lower ends of the depressing blades. This fastener provides the fastening of a compressible sheet such as an insulator sheet or carpet to an interior decorative panel in an automobile, for example, by having the tubular part set around the pillar of the male member with the depressing blades kept in an upright position, causing the head of the pillar to force the depressing blades down to a level position thereby bringing the projected parts into fast engagement with the underside of the head of the pillar and nipping the compressible sheet fast in position between the male member and the female member.

Abstract: A combined metal and plastic standoff for supporting a circuit board in fixed spatial relationship with another element comprises a rigid plastic body of appreciable length to produce the standoff effect and a metal retaining member integrally mounted on the plastic body at an operative end thereof. The metal retaining member has main and retaining portions, the main portion being fixedly disposed within the plastic body and the retaining portion extending outwardly from the plastic body having a resilient reverse bend segment, and being adapted for engagement with the circuit board or other element by an essentially longitudinal motion of the standoff along the axis of the body length to physically secure the circuit board or other element to the plastic body adjacent to the operative end.

Abstract: A pin comprises a head portion, a shank portion, and an end portion flared gradually to a dimension transverse to the pin axis greater than the shank portion. The end portion is slotted to afford resilient resistance to entry and withdrawal into a hole. The pin head portion is disc-like, the shank portion is of uniform circular cross-section about the pin axis, and the shank merges gradually into the slotted end portion to define an hollow oval merging at the tip as a bight, the end portion thus being adapted for snapping into a suitable hole.The pin is especially adapted to use with a circuit element carrier having an inverted U-channel in which the element is carried. The element may be inserted into a pair of holes in the top and bottom wall of the inverted U-channel, so that the shank of the element serves as a stop to prevent longitudinal escape of an element beyond the pin shank. The pin may be withdrawn after insertion and reused in the same or other holes of the same or other like carriers.

Abstract: The invention relates to a one-piece plastic fastener that has a shank, an enlarged head on a rear end of the shank, and resiliently movable bifurcations at the front end of the shank, the medial portion of the shank being wider than each of its ends to provide a shoulder and being flexingly contractable widthwise so that the fastener enters aligned holes in workpieces to be joined with a snap action. The shank is bifurcated along its length, and the forwardly opening slot between its bifurcations or legs is partially bridged by a tension-adjustment member, formed integrally with the bifurcations along one side thereof and extending inwardly from the side of the slot for a predetermined distance. The member controls or determine the amount of force required to move the legs or bifurcations toward each other during insertion into or removal of the fastener from the hole in the workpiece.

Abstract: A button assembly is disclosed for attachment on a garment fabric, which assembly comprises a female or button part having an apertured shank and a male or fastener part having a pointed shank for insertion into the aperture of the female shank. The button assembly is provided with means for expelling the air entrapped within the aperture of the female shank which would otherwise cause rupture of the button part.

Abstract: The cufflink includes a decorative head element disassembly assembled to a shank and keeper unit. The decorative head element has a hole in which the shaft head with the aid of a spring which is mounted inside the element.
