  • Patent number: 6247209
    Abstract: A capped rivet has a cap 10 with an exposed topside 14 and an inside 18 and further has a rivet part 20 with a rivet shank 22 and a rivet flange 24. The rivet shank 22 extends away from the inside 18 of the cap 10 and the rivet flange 24 extends transverse to the axis 23 of the rivet shank 22. The rivet flange 24 is firmly attached to the cap 10, and a reinforcing element 26 is arranged at the underside 25 of the rivet flange 24.

  • Patent number: 6170135
    Abstract: A watertight press fastener part formed of an eyelet part (1 or 3) including an eyelet body (2 or 4) or of a ball part (5) including a ball body (6) and a cap rivet (7) which is fixable to a flat material (9), preferably in the form of a climate membrane, in a watertight manner by riveting. An elastically deformable sealing element (11 or 13) which is constructed as a molded part contacts the flat material (9). This sealing element is penetrated by the rivet shank (8) of the cap rivet (7) and has, in the assembled state, due to the deformation of the rivet shank, a press face which is formed in an analogous manner by deformation and which surrounds the axial opening (10) of the press fastener part. Together with a counter-face at the eyelet part or at the ball part, the press face defines the clamping area for the flat material (9).

  • Patent number: 6170129
    Abstract: The press fastener comprises, in addition to a press fastener ball fixed to a first carrier web, a press fastener eyelet firmly connectable to a second carrier web by a rived shaft emanating from a rivet cap and passing through a central perforation. A simple construction involving low manufacturing cost, with high durability, i.e. a high number of closing and opening cycles, can be achieved if the press fastener eyelet is formed by a substantially annular, plastic moulding having the central perforation and comprising a round ball reception area and a temporarily widenable locking area which tapers towards the insertion end for the press fastener ball and extends roughly coaxially to the ball reception area. the said plastic body comprises a ring flange-like outer edge, to which is connected in axially displaced manner the central area having the central perforation.

  • Patent number: 6047449
    Abstract: In a capped rivet comprising a cap having an exposed upper surface and a lower surface, and a rivet having a rivet shaft extending in a direction away from the lower surface of the cap, a rivet flange extending in a horizontal direction away from an axis of the rivet shaft for fixedly attaching the rivet to the cap, and a pair of support portions disposed between the rivet shaft and the cap, extending substantially parallel to the lower surface of the cap, and formed by making a pair of apertures in the rivet flange and bending two portions of the rivet flange along bending lines respectively extending between the apertures and the rivet shaft, one support portion covers the other support portion by bending in such a manner that a surface of the one support portion that faces away from a lower surface of the cap at least partly contacts a surface of the other support portion that faces toward the lower surface of the cap.

  • Patent number: 5745964
    Abstract: A push-button closure part including a contoured button, a metallic rivet part having a rivet shank projecting from the underside of the button and an approximately radially extending, round rivet flange. The closure part includes a push button eyelet for slipping onto the rivet shank through a central opening. The rivet shank is deformed in a shallow S-shape which causes flexible material clasped between the rivet flange and the eyelet to be pressed between the edge of the central opening of the eyelet and rivet flange and also between the surrounding outer edge of the eyelet and the rivet flange.
