Including Stiffening Means Patents (Class 411/462)
  • Patent number: 8100619
    Abstract: A corner-cut corrugated fastener in accordance with the principles of the invention includes one or more features to facilitate fastening corner joints. The corrugated fastener includes a corrugated body member having a leading edge and a trailing edge opposite the leading edge. The corrugated body member may have a notch along the trailing edge, or chamfers at opposing ends of the leading edge, or both a notch along the trailing edge and chamfers at opposing ends of the leading edge. Additionally or alternatively, the corrugated body member may include a corrugation that extends a full length of each lateral edge extending between the leading edge and the trailing edge in order to provide enhanced strength.

  • Patent number: 6893197
    Abstract: A cage is adapted to hold the nut. The cage is formed from a sheet of material into top, bottom, and side walls. A protrusion extends between adjacent walls and is formed from repositioned material and/or an expanded portion of the sheet of material. The protrusion resists angular movement between the adjacent wall segments. The protrusion also pushes against an adjacent surface to resist angular movement. A method of manufacturing includes stamping a blank for a cage from a sheet of material. In addition, the method includes forming a protrusion on the sheet material by repositioning a corresponding area of the sheet material and bending the blank along a line passing through the protrusion and the corresponding groove. In a preferred version of this method, the stamping of the blank and the forming of the protrusion are done as part of a single stamping operation.

  • Patent number: 6866458
    Abstract: A fastener for securing a drywall work piece to a metal substrate. The fastener includes an elongated flat body carrying a securing member and having a driving head disposed at a substantially right angle to the elongated flat body. The driving head defines a bore therein surrounded by a downwardly directed flange having a distal cutting edge which cuts the top paper laminate of the drywall allowing the head to countersink into the drywall without damaging the top paper laminate.

  • Patent number: 6722095
    Abstract: A seam plate for use in connection with securing membrane sheets to underlying roof decking substructure comprises a substantially rectangular plate having a central aperture for receiving a bolt fastener. Upstanding rib structure is provided upon the plate so as to provide different regions thereof with different rigidity, flexibility, and bendability properties. The rib structure can have, for example, a substantially diamond-shaped configuration or an X-shaped configuration for respectively providing corner regions of the plate with increased or decreased flexibility. A plurality of downwardly extending projections, having substantially V-shaped cross-sectional configurations, are provided upon the underside of the seam plate so as to engage the membrane sheets and retain the same at their desired locations upon the underlying roof deck substructure assembly.

  • Patent number: 6325740
    Abstract: The hardness of the outer peripheral surface of a small-diameter portion 47 and one side surface of a collar portion 52, which respectively rub against a belleville spring 39a, is set at HRc45 or higher, thereby enhancing the wear resistance of these surfaces. On the other hand, the hardness of a fastening tubular portion 51 is set at HRc3O or lower, thereby making it difficult for the fastening tubular portion 51 to be damaged or cracked when it is fastened.

  • Patent number: 5971649
    Abstract: A ring binder mechanism adapted to be secured to a cover is disclosed as including a substantially rigid upper curved housing supporting a pair of plates to which three pairs of half-ring members are mounted, and a pair of rivets for engagement with the cover. The plates are pivotably movable between a first configuration in which the pairs of half-rings are closed, and a second configuration in which the pairs of half-rings are open. Each rivet includes an anchor plate to abut the cover and at least one claw penetrable into said cover in order to secure the ring binder mechanism to the cover, and the anchor plate includes a number of ridges or troughs.

  • Patent number: 4936161
    Abstract: A cable length adjuster with push and lock attachment for attaching and adjusting the length of a cable with respect to a support member. The cable length adjuster includes a stud having an externally threaded end portion and an intermediate boss formed with a polygonal-shaped exterior surface having a plurality of flat faces. A sleeve has a complimentarily shaped, polygonal cross section bore and is non-rotatably engageable with the boss on the stud. A nut is threadingly connected to the threads on the stud. The nut has a polygonal exterior shape to slidingly and non-rotatably support the sleeve. A spring is mounted between the nut and the sleeve to bias the sleeve into engagement with the boss on the stud. The cable is connected to the nut. Retraction of the sleeve from engagement with the boss on the stud enables the sleeve and the nut to be rotated thereby varying the overall length of the nut and stud through the threaded engagement of the nut with the stud.

  • Patent number: 4803823
    Abstract: The fastener can be made of metal or plastic in the form of a semi-flat disc or plate, with some reinforcing ridges if required. The disc or plate can be of various geometric shapes and dimension. At the center of the disc or plate surface is a small hole for inserting an anchoring screw, nail or bolt. On the underside of the disc or plate, vertical projections extend downwardly at angular positions corresponding to 0, 90, 180 and optional 270 degrees with respect to the small hole. The fastener is placed at the intersecting corners formed by abutting edges of rigid insulation boards, arranged in a "stack" or "running" bond pattern. The vertical projections of the fastener insert down into the aforementioned intersecting corners. These vertical projections resist insulation lateral movement or creep after securement of the rigid insulation corner fastener.

  • Patent number: 4509232
    Abstract: An attaching device for attaching a socket member of a snap fastener to a garment has a post having a circular flange extending from a cylindrical stem and a cap mounted thereon. The circular flange has a central portion, an intermediate inclined annular step, a radially outwardly extending annular shoulder, and a plurality of radial ribs extending radially outwardly from an end of the stem to the inclined annular step. The central portion of the flange has a surface adjacent to the inclined annular step which is held against a rounded wall of the cap. The end of the post is axially spaced from the rounded wall of the cap to provide a clearance therebetween. The annular shoulder of the flange is locked in position by an annular curled rim of the cap. Any impact force applied when the attaching device is staked on the socket member is distributed uniformly to the flange, preventing the cap from being deformed.
