Patent number: 7846187Abstract: 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.Type: GrantFiled: January 29, 2004Date of Patent: December 7, 2010Inventor: Roger P.

Patent number: 7775754Abstract: 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.Type: GrantFiled: February 16, 2006Date of Patent: August 17, 2010Assignee: FCI Holdings Delaware, Inc.Inventors: Karl Anthony Calandra, John G. Oldsen, Walter John Simmons, Walter Neal Simmons

Publication number: 20090196708Abstract: A shear screw has predetermined breaking points in two planes, separated axially from one another, and it has centrally a blind hole extending over a substantial length and having a cross section which is suitable for transmitting a torque to the shear screw by means of a pin-like tool of adapted dimensions which can be inserted into the blind hole. The blind hole extends to about level with the predetermined breaking point which is arranged in the lower region, facing the end face of the shear screw, of the latter and has a strength greater than that of the other predetermined breaking point.Type: ApplicationFiled: November 17, 2008Publication date: August 6, 2009Inventors: Ing Gart Stauch, Volker Markgraf, Rainer Bachmann, Peter Grotsch

Publication number: 20090191019Abstract: 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.Type: ApplicationFiled: January 29, 2008Publication date: July 30, 2009Applicant: DISNEY ENTERPRISES, INC.Inventor: Jerry Carl Billings

Publication number: 20090185879Abstract: 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.Type: ApplicationFiled: January 22, 2008Publication date: July 23, 2009Inventor: William D.
