摘要:
A punch rivet for fastening individual components to one another of which at least one component is formed by a workpiece of composite material, with the punch rivet having a flange of larger diameter, a rivet section of smaller diameter and a ring-like component contact surface at the side of the flange adjacent the rivet section and surrounding the rivet section, with the rivet section having at its free end a ring surface for the piercing of the two workpieces which stands at least substantially perpendicular to the central longitudinal axis of the punch rivet and an inner concave ring surface which forms the transition from the end of the punch rivet into the hollow internal space of the rivet section. Ribs extending parallel to the longitudinal axis are provided at the generally cylindrical outer surface of the rivet section and preferably extend up to the free end face of the rivet section. In addition, a method is claimed.

The invention relates to a riveting element (R) for riveting parts which are made from composite materials (M1 and M2) and provided with a through-hole. The invention is characterized in that it consists of: a hollow bushing (200) including, at one end, a head (210) bearing on the surface of one of the parts to be assembled and a hollow rod (220); and a semi-tubular insert (100) including a first end (110) capable of being inserted into the hollow part of the bushing (200) and an open end (130) capable of deforming in order to form an enlarged base that bears on the surface of the other part that is to be assembled once the insert (100) is translatably locked inside the bushing (200). The invention also relates to the installation tool configured for one such element.

A fastening system includes a first connecting member, a second connecting member, a rivet, and an elastic member. The second connecting member is positioned on the first connecting member, and defines a receiving groove. The rivet extends through the first connecting member and the second connecting member, and rivets the first connecting member and the second connecting member together. The rivet forms a riveting flange at an end adjacent to the second connecting member. The elastic member is received in the receiving groove of the second connecting member, and compressed by the riveting flange to generate a predetermined positive pressing force between the first connecting member and the second connecting member. A fastening device for manufacturing the fastening system is also provided.

The present invention provides a system and method for securing a captive rivet to a material. Briefly described, one embodiment is a captive rivet comprising a captive rivet head; a captive rivet shank coupled to the captive rivet head; and at least one capture region disposed on a lower portion of the captive rivet shank.
摘要:
A hand held vise pliers tool designed to aid an upholsterer, or a similar craftsman, in setting fasteners, such as snaps or grommets, by providing a uniquely designed upper die and lower die that are integrally attached to jaws of a vise pliers tool. The upper die is designed to receive and crimp a cap portion of a fastener, such as a snap fastener, and the lower die is designed to receive and crimp a socket portion of the same. A method of attaching the upper and lower dies to the jaws of the base tool is also described, wherein the jaws of the base tool are mechanically ground to a predetermined thickness and surface porosity, and the upper and lower dies are silver soldered to the respective jaws.
