  • Patent number: 10113581
    Abstract: Bolt retention threads are provided adjacent the proximal end of the body coupling aperture of a body isolator. A bolt has cooperating bolt retention threads and body coupling threads on the shaft. These body coupling threads have a diameter to permit the external body coupling threads to pass through the internal bolt retention threads without requiring threaded engagement therebetween. The cooperating bolt retention threads are axially positioned relative to each other to enable the entirety of the external bolt retention threads to be threaded completely through the internal bolt retention threads to capture the bolt within the body coupling aperture in a captured floating configuration. In the captured floating configuration, the external body coupling threads and the distal end of the shaft extend out of the distal end of the body coupling aperture and the bolt is allowed to float laterally within the body coupling aperture.

  • Patent number: 8574271
    Abstract: A screw fixation system includes a plate having opposed first and second surfaces, and a hole defined in the plate which extends between the first and second surface. A screw is included having a head and a shaft extending from the head and defining a longitudinal axis for the screw, the shaft of the screw being configured and adapted to be inserted into the hole. A retainer is circumferentially positioned around the shaft of the screw and proximate to the screw head. The retainer is configured to engage with the plate proximate the hole when the shaft of the screw has been inserted into the hole so as to resist removal of the screw from the hole and to allow removal of the screw from the hole when a preset torque is applied to the screw.

  • Patent number: 8511956
    Abstract: An exemplary fastener used for connecting at least two components together includes a bolt, a shell, and an elastic member. The bolt has a head, a shaft, an engaging portion, and a threaded portion in series. A diameter of the engaging portion is larger than a diameter of the shaft and a diameter of the threaded portion. The shell has a side wall and a collar extending inwardly from a bottom of the side wall. The collar defines a through hole therein. A diameter of the through hole is slightly smaller than the diameter of the engaging portion of the bolt. The elastic member is sandwiched between the head of the bolt and the collar of the shell. The bolt with the elastic member is received in the shell, and a top of the engaging portion of the bolt abuts against a bottom of the collar of the shell.

  • Patent number: 8506224
    Abstract: A fastener including a bolt and a grommet assembly attached to the bolt for fastening to a work piece. The grommet assembly includes an upper grommet, a lower grommet attached to the upper grommet, a retainer ring, and a housing that houses the retainer ring within the lower grommet. The upper grommet is inserted into a hole at one side of the work piece and the lower grommet is attached to the upper grommet through the hole at an opposite side of the work piece. The retainer ring is inserted into the lower grommet and encapsulated by the housing. The bolt is inserted into the grommet assembly, and the retainer ring engages the bolt such that a plurality of pressure pads extending from a plurality of corresponding spring beam elements of the retainer ring reside in an annular groove of the bolt. The grommet assembly captivates the bolt onto the work piece, while providing a positive hold out of the bolt.

  • Patent number: 8434983
    Abstract: An exemplary locking assembly includes a locking member and a sleeve. The locking member includes a locking portion, a neck portion, and a head portion. One end of the neck portion is connected to the head portion, and another end of the neck portion is connected to the locking portion. An outer diameter of the locking portion is larger than that of the neck portion. An outer diameter of the locking portion is larger than that of the neck portion. The sleeve defines a through hole therein for holding and guiding the locking member. The through hole includes a first part. The sleeve further includes a restricting portion extending out from an inner surface of the through hole adjoining the first part of the through hole. After locking portion of the locking member passes through the restricting portion of the sleeve, the restricting portion blocks the locking portion from sliding out of the sleeve.

  • Patent number: 8403612
    Abstract: A fastener assembly for attaching a fastener to an opening of a sheet material is disclosed. The sheet material is typically located adjacent to a base structure and the fastener assembly affords radial movement of the fastener relative to the opening of the sheet material. The radial movement allows the fastener to be aligned with a desired location on the base structure, e.g. a threaded aperture—after being attached to the sheet material. In this manner, the fastener assembly provides for the placement of the fastener in difficult to reach and/or see locations until it can be attached to the base structure.
