  • Patent number: 7296957
    Abstract: A method facilitates assembling a gas turbine engine assembly including at least a first member and a second member. The method comprises inserting a threaded fastener through an opening formed in a flange, and providing at least one shank nut including a flanged mating end, an opposite non-mating end, and a body extending therebetween. The body includes an internal surface, an external surface, and a centerline extending between the body ends. The flanged mating end includes a substantially planar exterior surface that is aligned perpendicularly to the centerline and an annular groove that extends from the exterior surface at least partially towards the non-mating end. The method also comprises securing the assembly together such that the mating end is positioned flush against the flange and such that the threaded fastener extends at least partially into a bore extending through the shank nut and defined by the shank nut internal surface.

  • Patent number: 7226263
    Abstract: A device for connecting component parts includes a blind rivet nut adapted to be anchored in one component part by a riveter which has a threaded stud; a spacer which is in threaded engagement with the blind rivet nut and, by being screwed-out, reaches a position in which it is supported at the other component part; a connecting screw adapted to be screwed into the blind rivet nut; and a torque transmitting intermediate member, which is accommodated in a receptacle of the spacer and transmits a torque onto the spacer when the connecting screw is screwed in. For anchoring the blind rivet nut in the one component part, the threaded stud is capable of being inserted into the intermediate member and the spacer and then being screwed into the blind rivet nut without causing the spacer to be rotated in its screw-out direction.

  • 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.

  • Patent number: 7207762
    Abstract: An attachment device for attaching a substrate to a support structure includes a housing having a space defined by facing wall portions. The space captures a rotatable push nut with flexible teeth. The housing is attached to the substrate using a flange positioned opposite one of the wall portions, the substrate being crimped between the flange and the wall portion. The device may be pushed onto a threaded stud to rapidly affix the substrate to the support structure. The push nut may be rotated within the housing to disengage it from the stud and thereby remove the substrate from the support structure.

  • Patent number: 7160047
    Abstract: A functional element arrangement which includes a functional element which is to be mounted on a component, especially but not exclusively on a brittle or non-rigid component made of a material containing cavities or pores, e.g. plastic, wood, metal foams, plastic or metal filled with hollow bodies, or another relatively soft material, selectively embodied as a sandwich construction or as a composite material e.g. in the form of a single layered or multilayered structure comprising, for example, two layers of sheet metal or plastic and a core made of one of the above-mentioned materials. The invention is characterized in that it is provided with an auxiliary assembly element which enables the functional element to be blocked using forming techniques when it is mounted on the component in a riveting process or a stamping and riveting process.

  • Patent number: 7086817
    Abstract: A cage nut assembly includes a nut having a cylindrical portion extending from a plate portion. The nut is encaged in a cage such that the cylindrical portion extends through an aperture in the cage. The cylindrical portion of the nut is collapsible such that the nut collapses and provides a plurality of flanges upon an application of force. The flanges are folded or curved/mushroomed such that the plate portion of the nut is suspended within the cage so that the nut will not, or will minimally, stick to the cage or workpiece when coated with e-coat or ELPO. Upon torqueing a fastener into place, the flanges are bent up to allow the plate portion to interface with the cage or a workpiece to provide a solid joint.

  • Patent number: 6969053
    Abstract: The present invention provides a strut mount comprising an inner member (12) to which an upper extremity of a rod of a buffer is fixed, an outer member (14) attached to a vehicle while surrounding an outer circumference of the inner member, and an elastomer (16) interposed between both members to dampen vibration, wherein an attachment piece (28) of an outer fitting (14) and an attachment plate (2) of the vehicle body are curved in the form of a sphere to raise rigidity and improve vehicle running stability. Besides, a non-fastening surface portion (36) is provided by being lowered via a different level portion (34) around a bolt fastening surface portion (30) of the attachment piece (28), preventing rubber burr from being produced on the fastening surface. Furthermore, by the use of a caulking nut (52) stuck to the underside of the attachment piece (28), the weight of the products can be reduced, and cost reduction is accomplished by laborsaving during operations.

  • Patent number: 6899498
    Abstract: A Spring fastener with critical configuration of the barbs, which allow the extraction of the fastener without destruction of the slot and/or the fastener. This critical configuration of the barbs allows spring fasteners to be used in slots of various widths and prevents rattling, which would take place in the case of spring fasteners of the present state of the art. The critical configuration is based on the special dimensions and special shape of the barbs with regard to the parts and the slots involved in assemblies of the spring fasteners and the parts. Assemblies of miscellaneous parts connected together by means of such spring fasteners, as well as vehicles comprising such assemblies may be made.

  • Patent number: 6761520
    Abstract: A threaded blind insert includes a shank with an axial bore therethrough having a head at one end and a threaded region of the bore at the opposite end. The wall of the shank between its outer surface and the bore includes a weakened deformable portion created by a reduced outside diameter of the shank in that area. A reinforcement collar integral with the shank is located at approximately the middle of the deformable portion of the shank thus providing a more rigid area at the collar which creates bulges in the deformable portion on either side of the collar when the insert is compressed. A flange located adjacent the underside of the head of the insert has an outer diameter greater than the shank but less than the head. When fitted into a mounting hole of a workpiece, the flange centers the insert and provides an annular gap between the shank and the mounting hole.

  • Patent number: 6709210
    Abstract: A fastener having a head and two expandable legs. The fastener further has a Y-shaped funnel configuration, which has been formed by a partial cut of the legs. The sides of the Y-shaped funnel comprise inwardly bent portions which are designed to extend into the slot of an object. The bent portions produce jamming and clamping when an expanding member is inserted through a hole on the head, resulting to highly improved pulling force. The fastener may be used in slots of different widths and may be pulled easily out of the slots, if so desired, in contrast with the fasteners of the present state in the art. Further, the fastener may be used in vehicles to connect one or more parts together.
