  • Patent number: 10024352
    Abstract: A fastener is disclosed. The fastener can be used to couple together two or more parts in an electronic device. The fastener may include a head coupled with a platform having a shaft extending from the platform. The head is coupled with the platform in a manner that allows the head to decouple from the platform. For example, the head is secured with the platform by an adhesive that provides an adhesive bonding force. In this regard, a rotational force applied to the head that is greater than the adhesive bonding force causes the head to decouple from the platform. The shaft may include several blades and several protrusions. The blades may be used to engage one of the parts. The protrusions may also engage the same part as the blades, and interlock with the part to provide a retaining force that prevents the fastener from decoupling from the parts.

  • Patent number: 7846187
    Abstract: A closure for an open headed medical implant, such as a bone screw. The closure having a cylindrical body having an axis of rotation and also having a threaded radially outer surface. The body having a plurality of bores that open onto a top surface of the body and that are parallel to but spaced from the axis of rotation. In one embodiment the closure also has a break-off head centrally attached by a neck to the top surface of the body. Preferably, the body also includes an axial threaded bore that extends from a bottom to the top of the surface body, but that is only exposed when the break-off head breaks away. In another embodiment a tool is used to insert the closure in the implant without a break-off head and a central threaded bore of the closure receives a set screw.

  • Patent number: 7775754
    Abstract: A nut having an injection-molded insert or delay stopper is threaded onto an end of an anchor. A capsule containing a resin component and a catalyst component and the other end of the anchor are positioned in a bore hole in a mine roof, mine wall, side of a hill, concrete wall, or concrete floor. The threaded end of the nut contacts the insert and rotation of the nut rotates the anchor, breaking the capsule and mixing the components. After the components set, increased torque is applied to fracture the insert and move the nut up the threaded end of the shaft against roof stabilizing components on the shaft.

    Abstract: A safety fastener capable of retaining portions thereof in the event of breakage is disclosed. The safety fastener includes a through hole along the longitudinal axis of a shaft. A secondary member, such as a wire rope, may be disposed within the through hole. Capturing members, such as balls sized larger than the through holes may be swaged or crimped to both ends of the secondary member, thereby capturing the shaft between them. In the event of breakage, portions of the shaft may remain substantially in place being confined by the secondary member and capturing members. Inspection of the safety fastener may include determining that the secondary member is loose relative to the shaft, thereby indicating that no gaps or separation has occurred in the shaft.

  • Publication number: 20090185879
    Abstract: A fastener system having a threaded shaft and a threaded body assembly. The threaded body assembly includes first and second bodies each having a threaded bore. A frangible member couples the two bodies together in an initial configuration. The two bodies are threaded onto the shaft in their initial configuration and, after one of the bodies has reached its final position on the shaft, the other body can be rotated relative to the one body and the threaded shaft thereby severing the frangible member and bringing engagement surfaces on the two bodies into bearing contact to inhibit loosening. The two bodies include recesses in their respective engagement surfaces. At least one of these recesses provides a space in which a stub of the frangible member is received when the two bodies are engaged together. The fastener system can be employed with the locking mechanism of an adjustable steering column assembly.
