    • PROBLEM TO BE SOLVED: To disclose a fastener engaged with aligned holes through workpieces. SOLUTION: The fastener comprises a pin member having a transition portion radially reduced in diameter to extend from a smooth cylindrical shank portion to a threaded portion. The fastener is provided with a sleeve member and a mounting means. The mounting means comprises a collar, a nut or any other possible mounting means. In one embodiment, a workpiece is formed of a plurality of materials, and the materials include composite, metallic, or metallic/composite structures or any combination thereof. In a specific embodiment, the fastener has interference performance of 0.0127-0.254 mm (0.0005-0.0100 inches) in composite structures without risk of composite delamination or damage. As a result of the fastener interference, gaps between the fastener and the structure are eliminated to provide good electrical conductivity between components. As a result, the potential for electrical sparks is reduced to provide a safer fastener for use with aerospace applications. COPYRIGHT: (C)2008,JPO&INPIT
    • 要解决的问题:公开通过工件与对准的孔接合的紧固件。 解决方案:紧固件包括销构件,该销构件具有径向减小的过渡部分,以从平滑的圆柱形柄部分延伸到螺纹部分。 紧固件设置有套筒构件和安装装置。 安装装置包括套环,螺母或任何其它可能的安装装置。 在一个实施例中,工件由多种材料形成,并且材料包括复合材料,金属或金属/复合结构或其任何组合。 在具体实施例中,紧固件在复合结构中具有0.0127-0.254mm(0.0005-0.0100英寸)的干涉性能,没有复合分层或损坏的风险。 作为紧固件干涉的结果,消除了紧固件和结构之间的间隙,以在部件之间提供良好的导电性。 结果,减少电火花的可能性,以提供用于航空航天应用的更安全的紧固件。 版权所有(C)2008,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a member joint structure for more stably jointing members to each other by using a bolt with its head arranged near a joint area between the members. SOLUTION: In the member joint structure, a bolt 3 and a nut 4 threaded to the bolt 3 are relatively rotated to be threaded to each other forward and backward and the bolt 3 and the nut 4 are used for fastening and joining two members as a frame material 1 and a corner material 2 to each other. The structure comprises an operation receiving part 5 for receiving external rotating operation of the bolt 3 around an operation axis L extending to the direction of crossing the axial center thereof, and an operation converting part 6 for converting operating force received by the operation receiving part 5 into the rotation of the bolt 3 relative to the nut 4.

    • PROBLEM TO BE SOLVED: To provide a wall-mounting screw fitting easily mounted and firmly fixable to a gypsum board without leaving a large opening after removed.
      SOLUTION: A hook part 15 is held to screw a screw coil part 13 with a metal bar body bent in spiral shape, into the gypsum board B. When the screw coil part 13 is completely screwed into the gypsum board B, a washer 16 is pressed to the surface of the gypsum board B by a collar part 14. The washer 16 is deformed into flat shape being pressed by the collar part 14 to generate spring force of pushing the gypsum board B. The screw coil part 13 is thereby fixed to apply force to the gypsum board B and prevented from falling from the gypsum board or getting loose. Only a hole approximately equivalent to the diameter of the metal bar body 12 is bored in the gypsum board B, and when removing the wall-mounting screw fitting 11 from the gypsum board B afterwards, only a small hole is left, and a removal mark is not conspicuous.
