    Abstract: A clinch-type fastener is formed by simultaneously creating an undercut during the same forging that creates the head and displacer of the fastener. A fastener blank is compressed end-to-end between top and bottom dies whereby the axial compression of a blank causes the outward bulging of the shank at its midline. Simultaneously, a tapered end point and a tangential interference band are formed provided by a curvilinear-shaped bulge in the shank. As the bulge is formed an undercut is created between the bulge and a shoulder which extends downwardly from a head of the fastener. This method of formation and the fastener produced thereby are particularly suited to the manufacture of small clinch pins having a diameter in the range of 1.0 mm.

  • Patent number: 7901171
    Abstract: A blind fastener has a setting head portion and a shank portion having one end connected with the setting head portion and an opposite end with an internal thread or a threaded bolt receptacle. The shank has a sidewall with an outside diameter smaller than the diameter of the setting head portion, and is configured for close reception in an aperture of the workpiece prior to being upset. The sidewall has a deformation area that is disposed between the setting head portion and the internal thread or the threaded bolt receptacle, and is upset radially outwardly to secure the fastener to the workpiece. The deformation area includes a central circumferential region which provides sole weakening for the sidewall.

  • Patent number: 7901170
    Abstract: A holding device for holding an object having an opening includes: a first member inserted into the opening, having a cylindrical shape, and including multiple divisional portions divided by notches; and a second member including a shaft movable in the cylindrical shape and a head disposed on one end of the shaft and smaller than the opening and larger than an inner dimension of the cylindrical shape. Each divisional portion is expandable by the head so that the expanded divisional portion holds the object when the first member with the second member is inserted into the opening, and the first member is relatively displaced toward the second member.

  • Patent number: 7887273
    Abstract: A blind rivet includes a hollow rivet body having a longitudinally extending indented groove. The groove may be shaped to impart rivet setting characteristics that may be varied to provide desirable fastening characteristics for joints in a number of industries. The shape of the indentation on the rivet body may be varied to cause a portion of the rivet body to collapse and form a secondary head at a predetermined longitudinal location.

    Abstract: A modified anchor device for attaching a structure to a thin-walled work piece allows a structure, such as a luggage or utility rack, to be attached to a work piece, such as an automobile roof, without threaded fasteners connecting the structure to the work piece. The anchor device has an double-sectioned head having an upper head member and a lower head member The upper head member extends above the surface of the work piece a sufficient distance such that the upper head member engages the top surface of the structure, thus retaining the bottom side of the structure in face-to-face contact with the top side of the work piece.

  • Publication number: 20090217505
    Abstract: The invention relates to a gun rivet and a device for placing said rivet. The gun rivet contains a rivet head (1) with a collar (3) at one end and a rivet tip (6) at the other. The rivet body contains a cavity (7) in the form of a bore in a sleeve section (22). As with other gun rivets, the gun rivet is shot with a percussive-type action and with the aid of its rivet tip into an opening in two sheets (13, 14) that are to be joined together, until the collar comes to rest on the upper face of the upper sheet. A tensile bolt is then introduced into the cavity and is connected to the base (8) of the latter. This can be achieved by resistance welding. The tensile bolt is then drawn until a rivet head is formed on the opposite side of the two sheets. The tensile bolt is then detached from the gun rivet, for example by shearing. The tensile bolt can be re-used to place another rivet.

  • Patent number: 7566195
    Abstract: A blind rivet assembly includes a mandrel having a male threaded portion at its distal end to be screwed into an internal female threaded portion of a rivet body. The mandrel has a section of enlarged diameter adjacent the male threaded portion joined by a breaker groove to a pulling portion. The section of enlarged diameter is accommodated within an internal bore of the collapsing portion of the rivet body, the collapsing portion having a radial groove on the outer surface thereof for improving the radial expansion of the rivet when installed. A shoulder in the internal bore supports a sealing ring. When assembled correctly, the pulling portion breaks off at the breaker groove.

  • Patent number: 7520708
    Abstract: A device for sealing an opening in a structural member and/or for sealing a plurality of openings in overlapping members, or for hanging an object on a wall. The device includes a deformable member having a substantially cylindrical stem and a flange at a first end of the stem. In some embodiments the deformable member is constructed of a compressible material that has good sealing capabilities. The stem is configured to extend through at least one opening in the at least one structural member such that the flange abuts a surface of the structural member. A reinforcing sleeve extends around the stem and provides a protective barrier between the at least one structural member and the stem. The sleeve may be constructed of a relatively hard and durable material such as a polymer, a metal or a ceramic. In some embodiments the sleeve is substantially cylindrical with at least one tab extending from a lower end thereof. In some other embodiments the sleeve includes a flange at an upper end.

  • Patent number: 7223056
    Abstract: A blind rivet nut has a head configured as an annular flange and a shank comprising a head end, a foot end and a cylindrical bore closed at the foot end of the shank and extending from the head end to the foot end in lengthwise direction, and a second bore segment near the head end whose diameter is greater than the diameter of the first bore segment. The wall surrounding the second bore segment forms a plastically deformable region of the shank, and has an outer surface with the shape of a regular polygonal, in particular hexagonal, prism. To achieve a uniform and tightly sealing contact of the flange with the part accommodating the blind rivet nut, the wall thickness of the deformable region in the thinnest places is 4% to 6% of the least outside diameter of the deformable region.
