  • Patent number: 10555820
    Abstract: The present invention provides a spinal implant structure. The spinal implant structure comprises a first part, a second part and at least one expansion arm. The second part is disposed on the horizontal orientation of the first part and does not overlap with the first part. The diameter of the first part is larger than that of the second part. One end of the expansion arm is connected to the first part, and the other end of the expansion arm is free end. The expansion arm and the first part create an angle. The expansion arm includes a supporting arm. One end of the supporting arm is connected to the expansion arm, and the other end of the supporting arm is connected the second part. The support arm includes a plurality of structure weakness. When the distance between the first part and the second part changes, the support arm bends from the structure weakness, thereby the angle is increased and the spinal implant structure is expanded.

  • Publication number: 20150139748
    Abstract: Fasteners are generally described. In some examples, a fastener can be secured to a first member or it can secure a second (or further) member to the first member. The example fastener can include a body for location with respect to the first member. The example fastener can also include at least one latch which can be located with respect to the body. The latch can move laterally with respect to the body from a non-latching position to a latching position. The example fastener can also include an actuator. The actuator can protrude from the body as the actuator moves from an inactive position to an active position. When the actuator is in the inactive position and the at least one latch is in the non-latching position, the body can be located with respect to the first member.

  • Patent number: 9012006
    Abstract: A multi-layer assembly, such as a sound damping metal laminate used in the automotive industry, having first and second rigid layers and an adhesive layer in between. A retention feature in the form of a raised embossment may be formed in one or more of the rigid layers and may be located near a fastening hole, which accommodates a nut and bolt or some other type of fastening device. The retention feature may impart rigidity and improved stiffness to the multi-layer assembly in the area surrounding the fastening hole, and it may also create a space between the rigid layers that is generally devoid of adhesive from the adhesive layer. This, in turn, can improve the long term performance of the multi-layer assembly by addressing issues such as compression set, spring back and/or stress relaxation. Methods of manufacture and other embodiments are also provided, including ones that accommodate multiple fastening holes, have discontinuous retention features, and use welds in place of nuts and bolts, to name a few.

  • Patent number: 8979453
    Abstract: A blind fastener including a pull-type core bolt having a shank with a head, and a sleeve having an elongated body with a head, and a tapered notch formed within an exterior surface thereof and defined by a tapered portion having a slope and a frictional enhanced surface. The core bolt is installed within the sleeve. During installation of the fastener within the plurality of work pieces, an axial force is applied to the core bolt the head of the core bolt engages the sleeve, and a bulb is formed on the elongated body of the sleeve, the bulb defining a portion of a bulbed portion. When a selected axial force is reached, the bulbed portion separates from the elongated body and engages axially the tapered portion of the sleeve, increasing the diameter of the bulb which engages a blind side of one of the work pieces.

  • Patent number: 8979452
    Abstract: An anchor bolt comprising: a shaft part with a male screw thread; and a head part connected to the shaft part and having an attachment hole with a closed-end bottom to receive a bolt therein defined at a tip surface of the head part and a breaking groove provided at an outer side surface of the head part. The breaking groove is formed at an outer surface of a portion in which the attachment hole is defined. A torque equal to or greater than a fixed value exerted on a tip portion between the tip surface and the breaking groove of the head part causes the breaking groove to be broken, thereby causing the tip portion between the tip surface and the breaking groove of the head part to be removed.

  • Patent number: 8961086
    Abstract: A fastener comprises a body having an enlarged head at a first end, a tapered ramp at a second end, a cylindrical shank disposed between the enlarged head and the tapered ramp, internal threads, and a cylindrical passage formed through the body between the first and second ends. The fastener further includes a generally cylindrical corebolt having first and second threaded sections separated by a third non-threaded section, the corebolt disposed within the passage of the body and a sleeve having a generally cylindrical passage therethrough and movably disposed over a portion of the corebolt. A nut is in threaded engagement with the corebolt and is disposed adjacent an end of the sleeve. An interface between the corebolt and the nut is configured to resist relative rotation of the nut with respect to the corebolt until the sleeve is in abutment with a workpiece.
