きるものである。Hereinafter, the present invention will be described in detail with reference to embodiments. As shown in FIG. 2 (a), the bolt 4 is formed by providing a male screw portion 5 at its base and a head 6 at its tip, and the diameter of the head 6 is the body of the bolt 4. It is formed to have the same diameter as the portion 26. A neck portion 27 having a smaller diameter than the head portion 6 is formed at the base portion of the head portion 6. The nut 3 is formed in a rectangular shape as shown in FIG. 2 (b), and a female screw hole 28 is formed in the center thereof. As shown in FIG. 2 (c), the washer 10 is formed in a U-shape by notching an insertion recess 9 which is open at one end. When connecting the pair of members 1 and 2 such as handrails by using the bolt 4, the nut 3 and the washer 10, one member 1 is provided with an insertion hole 29 opening at its end face and the inner side of the insertion hole 29. A nut fixing hole that communicates with the end and opens on the side surface of this member 1 (the lower surface that is inconspicuous with handrails)
30 is provided, and the nut 3 is fitted and fixed in the nut fixing hole 30 so that the female screw hole 28 communicates with the insertion hole 29. The diameter of the nut 3 is formed larger than the diameter of the insertion hole 2, and the nut 3 is fixed in the nut fixing hole 30. Member 1
The nut 3 can be attached to the above-described manner by providing the nut fixing hole 30 as described above, or by inserting the nut 3 into the insertion hole 29 without providing the nut fixing hole 30. Then, the bolt 4 is inserted through the insertion hole 29 so that the male screw portion 5 of the base portion of the bolt 4 is screwed into the female screw hole 28 of the nut 3. Thus, the bolt 4 is projected from the end surface of the one member 1 while being screwed into the nut 3. Further, the other member 2 is provided with an insertion hole 7 which is opened at its end face, and an operation hole 8 which is communicated with the rear end of the insertion hole 7 and which is opened at the side surface (the lower surface which is inconspicuous by the handrail) of this member 2. The diameter of the insertion hole 7 is larger than the diameter of the bolt 4 including the head 6,
In addition, it is formed smaller than the size of the washer 10. Then, the head 4 is inserted into the operation hole 8 by inserting the bolt 4 into the insertion hole 7, and the end surfaces of the pair of members 1 and 2 are brought into contact with each other. Next, the washer 10 is inserted into the operation hole 8 through the opening on the side surface of the member 2, the insertion recess 9 of the washer 10 is inserted into the neck 27 of the bolt 4 from the side, and the washer 10 is attached to the head 6 of the bolt 4. Lock to the base. In this state, by operating the head 6 and turning the bolt 4, the screwing of the male screw portion 5 of the bolt 4 with the nut 3 is deepened, the head 6 presses the washer 10, and the washer 10 operates the insertion hole 7. By engaging with the opening edge to the hole 8, the pair of members 1 and 2 can be connected via the bolt 4, the nut 3 and the washer 10 as shown in FIG. The openings exposed to the outside of the operation hole 8 and the nut fixing hole 30 may be closed if necessary. In addition, in the operation of operating the head 6 and turning the bolt 4, the outer peripheral surface of the head 6 is formed into a gear-shaped concavo-convex, and the tip of a tool such as a screwdriver inserted into the operation hole 8 is used to rotate the bolt-shaped gear. This can be done by hooking the unevenness and turning the head 6. However, in this case, it is difficult to turn the tool 6 strongly against the unevenness of the head 6 by sliding the tip of the tool, and the screwing of the bolt 4 to the nut 3 becomes weak, so that a gap is generated between the connecting end faces of the members 1 and 2. easy. Therefore, as shown in FIG. 3, a plurality of operation holes 31 are provided on the head 6 of the bolt 4 along the outer periphery thereof.
A thin object such as a nail may be inserted into the operation hole 31 and rotated. In this case, since the bolt 4 can be rotated with a strong force without slipping, the screwing of the bolt 4 with respect to the nut 3 becomes strong, so that a gap is generated between the connecting end faces of the members 1 and 2 or a grapple is generated. Can be prevented.

In the inserted state, the end faces of the pair of members are brought into contact with each other, and a washer provided with an insertion recess opened at one end is inserted into the operation hole, and at the base of the head, the insertion recess of the washer is provided on the outer circumference of the bolt. It was inserted, and the head was operated to rotate the bolt to screw the male screw part into the nut and to lock the washer at the opening edge of the insertion hole to the operation hole. Bolt the other part It is possible to connect a pair of members by inserting the washer into the operation hole, inserting the washer into the operation hole, inserting the washer insertion recess from the side of the bolt, and operating the head to turn the bolt. This makes it unnecessary to perform operations such as inserting a washer from the tip of the bolt or screwing a nut from the tip of the bolt into the operation hole, and the workability of connecting the members is improved. It is excellent. Also, because the nut was fixed in one member and the male screw part of the base of the bolt that was projected from the end face of this member was screwed into the nut shallowly, the bolt was supported by the nut and projected from the end face of the one member. It can be securely held in a closed state, and when the bolt is inserted into the insertion hole provided in another member, the bolt does not fall off from one member or retract inside one member. Is what you can do. Furthermore, since the bolts that are shallowly screwed into the nuts are brought into contact with the end faces of the pair of members and then deeply screwed into the nuts, the members can be connected easily and securely. It is possible to prevent a gap from being formed between the end faces of the and the backlash between the members.
