  • Patent number: 8621742
    Abstract: Apparatus and Method of use for an improved lock nut type of fastener. On a threaded rod, a set of one or two cavity locknuts are used with a sleeve like ferrule to lock a nut in a set position on the rod. For example a nut that is clamping a workpiece can be held in place (resisting if not preventing loosening) by suitable application of the ferrule and cavity locknut. The cavity locknut has a tapered funnel-like cavity in a nut face around the nut's threaded hole. Locking is accomplished by immobilizing the ferrule on the rod and against the nut to be held, orienting the cavity side of the cavity locknut toward the ferrule, and forcefully torquing the cavity nut against and around the ferrule so that it is crimped against the threaded rod by the tapered cavity in the nut.

  • Publication number: 20130214098
    Abstract: A pipe hanger clamp, formed by bending a flat section of metal bar or plate, has two vertical side members which have been cut so their side view is a ā€œCā€ shape. The lower arms of these two side members are joined by a horizontally extended end wall, about which the side members are bent. Holes in the end wall receive a mounting set screw into a captured nut and another nut to hold a pipe hanger rod for supporting a pipe. An overhead support is clamped between the set screw and the upper arms of the C-shaped side members, such that the load applied to the rod is generally edgewise to the plate thickness, and does not provide an unbending force on the clamp.

  • Publication number: 20130207528
    Abstract: An occupancy sensor may include a plurality of user-selectable mounting features that enable the sensor to be mounted to building structure in a variety of ways. The sensor may include: a nipple for engaging a connector associated with the building structure; one or more key hole slots for engaging fasteners associated with the building structure; and one or more flat side surfaces for engaging corresponding flat surfaces of a mounting plate associated with the building structure. A spring on the flat side surface may lock the sensor to the mounting plate. The nipple may be removable to allow the sensor to be flush mounted to the building structure. The sensor may also include a user-adjustable lens that enables a user to make discrete adjustments of the field of view of the sensor according to present levels. Other embodiments are disclosed and claimed.

  • Publication number: 20130206513
    Abstract: A linkage pin assembly is disclosed. The linkage pin assembly includes a grease fitting, a linkage pin, and a coupling. The grease fitting includes an outer shell. The outer shell encloses an internal cavity. The outer shell includes a thread blank having at a second end of the outer shell. The thread blank includes hardened lead threads. The hardened lead threads are induction hardened to at least RKW C 53. The linkage pin has an untapped hole. The coupling is between the grease fitting and the linkage pin. The coupling is formed when the hardened lead threads of the grease fitting create corresponding threads in the untapped hole of the linkage pin when the grease fitting is inserted into the linkage pin.

  • Publication number: 20130200615
    Abstract: In a method for influencing the thread geometry of an internal thread of a first component of an injection device for internal combustion engines, which is provided for carrying high-pressure fluid, wherein the first component has a tubular end portion and an internal thread is formed on the interior surface of the tubular end portion, and a second component having an exterior surface on at least a portion thereof so as to be received in the tubular end portion of the first component wherein the exterior surface is threaded so said second component can be screwed and clamped against a support surface of the first component, and wherein the tubular end portion on the external side is acted upon by a radial compression force allowing a plastic deformation. The tubular end portion is transformed thereby in such a manner that the internal thread obtains an inner diameter (D) continuously decreasing towards the free end.

  • Publication number: 20130193683
    Abstract: A fitting assembly for a high pressure system includes a tube assembly including a tube having an undercut near a first end. A gland is slidably coupled around the tube and has an exterior threaded surface. The gland forms a gland cavity adjacent an exterior surface of the tube. A spring collar is also slidably coupled around the tube between the gland and the first end of the tube such that a portion of the spring collar is disposed within the gland cavity. The fitting body has an inlet passage and a fitting cavity for receiving an end of the tube assembly. The open end of the fitting cavity has a threaded surface forming a threaded engagement with the threaded surface of the gland. This threaded engagement creates a primary and secondary seal in the fitting assembly. The secondary seal applies a force to the threaded engagement.

  • Publication number: 20130185917
    Abstract: A method for the attachment of a bolt element to a component is described. The bolt element has a head part having a contact surface and a shaft part extending away from the head part, the shaft part having a tip provided at its end remote from the head part, the tip merging into a thread cylinder, optionally via a cylindrical region. The bolt element is pressed with the tip to the fore against the component and the tip is pressed through the component until the side of the component adjacent the head part of the bolt element enters to contact the thread cylinder and the tip thereby generates a hole in the component. The bolt element is subsequently turned so that the thread of the thread cylinder forms an internal thread in the wall of the hole. A bolt element is also claimed.

    Abstract: A grab handle mounting assembly securable to a mounting surface includes a first mounting arm assembly securable to a mounting surface. The first mounting arm assembly defines a first male pin. A second mounting arm assembly is securable to a mounting surface and defines a second male pin. The assembly further includes a first tube having first and second open ends, wherein the first male pin is mateable within the first open end of the first tube and the second male pin is mateable within the second open end of the first tube. When the first and second mounting arm assemblies are secured to a mounting surface with the first and second male pins mated with the first and second open ends of the first tube, the first and second mounting arm assemblies impose a torsional force on the first tube.
