    • PROBLEM TO BE SOLVED: To provide a primary tapping screw spike of which the working process is simplified without requiring to use a drilling machine and by which a stationary effect of the screw spike is enhanced and which is hard to be loosed and dropped.
      SOLUTION: The primary tapping screw spike includes a body, a tension screw and a drill head. The body is of a hollow rod and is capable of accommodating the tension screw. A driving groove which fits a tool on the head of the tension screw is provided. A male thread which engages with a through hole inside the body is cut on the other end of the tension screw. The male thread protrudes outside the body and is engaged with a drill head so as to be threadable. A spiral protuberance tooth is provided outside the body. The screw spike is driven by the tool when being operated and then a hole is perforated in place by a drill head. The body is imbedded by permitting the tool to rotate the body accompanying it until the head of the body is incapable of being screwed. The body of the screw spike is fixed to be immovable. At this time, the male thread of the tension screw still follows and is screwed into the through hole of the body. The screw spike compulsorily allows the outside of the body to create the deformation action of outward expansion and is tightly fixed in place.

    • 要解决的问题:提供一个主要的自攻螺丝钉,其工作过程被简化,而不需要使用钻孔机,并且螺钉钉的固定效果被增强并且难以松开和下降 。

      解决方案:主自攻螺丝钉包括主体,张紧螺丝和钻头。 主体是中空杆,能够容纳张力螺丝。 提供了一种将工具安装在张紧螺钉的头部上的驱动槽。 在张紧螺丝的另一端上切割与主体内的通孔接合的外螺纹。 外螺纹突出到主体外面并与钻头接合以便可螺纹化。 在身体外部提供螺旋形突起齿。 当操作螺丝钉由工具驱动,然后通过钻头将孔穿孔就位。 身体被嵌入,允许工具旋转身体伴随它,直到身体的头部不能被拧紧。 螺丝钉的主体固定为不可移动。 此时,张紧螺丝的外螺纹仍然依次并拧入到主体的通孔中。 螺丝钉强制地允许身体外部产生向外膨胀的变形作用,并且紧紧地固定到位。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide an unfolding anchor fixing an instrument to a wall surface or the like by directly inserting an anchor body from an instrument bolt hole and completing attachment of the instrument by a single procedure.
      SOLUTION: This unfolding anchor is formed by a combination of the anchor body 2 having the intermediate portion of a cylindrical leg portion 4 divided into a plurality of legs 8 by long grooves 7 in an axis direction, and a bolt 3 inserted and screwed into the cylindrical leg portion 4. The legs 8 of the anchor body 4 are divided by the two long grooves 7 in order to form a horizontal section into an approximately semicircular shape. Folding joint portions 9 are formed at its both ends and intermediate portion, and blades or cutting edges 10 projecting in a diameter enlarging direction are provided at the other end of the cylindrical leg 4.
