Description

[Detailed description of the invention] The present invention relates to a nail for nailing and fixing a plurality of members to be fixed. In particular, the tip of the nail that has been nailed through the nail can be expanded and deformed to provide a holding force in the pulling direction. This is related to the nails that were made.

A conventional example of this type of nail is Utsukō 45-14218.
There is a locking clasp disclosed in No.

This conventional locking clasp is designed as shown in FIGS. 5 and 6, in which the tip of the locking protrusion a is given a bending tendency in advance, and the locking protrusion a is The auxiliary member b for correcting the bending tendency is inserted and held in a straight line, and after penetrating the fixed member, the auxiliary member b is removed and the locking protrusion a is bent so that it does not come out from the fixed member. It is starting to be retained.

However, in the case of the above-mentioned conventional locking clasp, it is necessary to give the tip of the locking protrusion a a bending tendency in advance at the time of manufacture, and in order to correct this, it is necessary to Since the auxiliary member b, which is unnecessary after penetration, is required, the cost per piece is high, and due to its structure, it is difficult to drive it into the member to be fixed.

The present invention was developed with the above in mind, and is a nail that has a simple structure, can be obtained at low cost, is easy to drive into the member to be fixed, and can be easily handled like a normal nail. This is what we are trying to provide.

Embodiments of the present invention will be described below based on the drawings.

In the figure, 1 is a nail consisting of a shaft part 2 with an acute angle tip and a striking part 3 provided at the base end of this shaft part 2.
The shaft portion 2 of this nail 1 is provided with an elongated hole 4 extending from near the tip to the base and penetrating in a direction perpendicular to the axis. This nail 1 is made of fiber reinforced plastic.

When fixing a plurality of members 5 and 6 to be fixed together, drive the nail 1 as shown in FIG. cut. Then, due to the residual stress caused by the force applied during cutting and the force applied during driving, the tips of the shaft portions separated by the elongated holes 4 are deformed and expanded as shown in FIG. 4. Therefore, this widening deformation portion acts as a resistance in the direction in which the nail 1 is removed, and the tip of the shaft portion 2 can be provided with a holding force in the direction in which the nail 1 is removed.

In addition, if the expansion width cannot be increased only by the above-mentioned residual stress, an external force is applied to actively expand the expansion width.

As detailed above, in the nail according to the present invention, since the shaft portion 2 is provided with the elongated hole 4 that penetrates from the vicinity of the tip of the shaft portion 2 to the base in the direction perpendicular to the axis, the fixed member 5, 6. After driving through the nail, the nail can expand its tip to provide a holding force in the pulling direction. It is a simple nail that does not require an auxiliary member like conventional ones or give bending tendency to the tip in advance. The structure can be obtained at low cost, and it can be easily driven into a member to be fixed in the same way as a normal nail, and furthermore, it can be easily handled one by one in the same way as a normal nail.
