By the way, for conventional nails, for example,
There is one disclosed in Publication No. 53-20608. As shown in FIG. 4, this conventional nail has a screw part 104 in the lower half of the body part 100, a ring part 105 in the upper half, and a circular band 106 between the screw part 104 and the ring part 105. The diameter of this circular band 106 is equal to or larger than the outer diameter of the screw portion 104.

(Problems to be Solved by the Invention) However, in such conventional nails, since the screw part 104 or the ring part 105 is not provided with any means for preventing reverse rotation, the nails may not be able to penetrate into the material to be driven after driving. When a rotational force in the return direction is applied to the nail, the screw portion 104 causes the nail to move in the direction of coming out, resulting in a problem in that the holding force is reduced.

Therefore, the present invention was devised to solve the above-mentioned problems of the conventional example, and its purpose is to provide a nail with a screw part and a ring part in the return direction in the material to be driven. The objective is to significantly increase the holding force by increasing the resistance to the rotational force of the bearing.

(Example) The present invention will be explained below based on the illustrated example. 1 to 3 show a nail showing an embodiment of the present invention. In FIG. 1, 1 is a nail body, and this nail body 1 includes a body part 2 and a body part 2. A head portion 3 is integrally formed at the rear end, and a tip portion 4 of the body portion 2 is formed into a pointed shape with a predetermined length. Furthermore, a plurality of ring parts 5 are formed in the lower half of the trunk 2 and extend outward in the radial direction of the trunk 2, and approximately the upper half of the trunk 2 is connected to the axis of the trunk 2. It has a screw portion 7 formed in a spiral shape with respect to the direction. The upper surface of the ring portion 5 facing the head 3 has a gently sloped surface 6a in a direction that receives rotation by the screw portion 7 during driving, and a steep surface 6b in the opposite direction that receives rotation by the screw portion 7. A concavo-convex portion 6 is formed.

In the above configuration, the nail body 1 enters into the material to be driven without being rotated during the initial and middle stages of driving. Next, in the later stage of driving, the nail body 1 is rotated by a predetermined angle by the screw portion 7 and is driven until the lower surface of the head 3 comes into contact with the material to be driven. In this way, during driving, the resistance due to engagement with the material to be driven is small, so an increase in driving resistance is avoided. On the other hand, when a rotational force in the return direction is applied to the nail body 1 in the material to be driven after driving,
The ratchet function in which the steep surface 6a of the uneven portion 6 engages with the material to be driven prevents the rotation of the body portion 2,
This prevents the nail body from coming off due to the screw portion 7.

Incidentally, in the above embodiment, the ring part 5 is formed in the lower half of the body part 2, and the screw part 7 is formed in substantially the upper half, but these may be formed in reverse. In this case, in order to obtain a higher holding force, it is desirable to form as in the above embodiment.

In addition, in the above embodiment, the diameter of the crest of the screw part 7 and the diameter of the crest of the ring part 5 are set to be approximately the same, but if the diameter of the crest of the screw part 7 is made larger than the diameter of the crest of the ring part 5, the driving When the screw part 7 enters the material to be driven in the latter stage, it is strongly engaged with the part of the material to be driven which has not yet been destroyed by the ring part 5 formed in the lower half of the nail body 1. The rotation of the body part 2 of the nail body 1 can be ensured, and the same effect improves the pull-out strength between the screw part 7 and the material to be driven, and as a result, the strength of the nail as a whole increases. It is possible to increase the pulling strength.

Furthermore, in the above embodiment, the uneven portion 6 is formed by the ring portion 5.
The ring part 5 is formed on the upper surface facing the head 3 of the ring part 5.
The lower surface facing the tip portion 4 may also be formed with a gentle slope in the direction of rotation by the screw portion 7, and an uneven portion with a steep surface in the opposite direction. In this case, the effect of preventing the nail body from coming off due to the action of the screw portion 7 is further enhanced.

Furthermore, the number of ring portions 5 formed in the axial direction, the spacing, etc. may be appropriately selected depending on the material of the material to be driven. The pitch of the uneven portion 6 of the ring portion 5 may also be set appropriately depending on the material of the material to be driven.

However, in the above embodiment, the ring portion 5 after driving
The steep surface 6b of the uneven portion 6 formed on the upper surface engages with the material to be driven and prevents rotation of the body portion 2, thereby reliably preventing the nail body 1 from coming off due to the action of the screw portion 7.

(Effect of the invention) The nail according to the invention has the above-mentioned structure and function, and when driving, it is no different from conventional nails.
The driving resistance is small, and after driving, the resistance to the rotational force in the return direction in the driven material increases due to engagement with the driven material, and the holding force (pulling strength) increases significantly. As a result, it is possible to provide reliable nails. Further, since it is only necessary to form the uneven portion on the ring portion, it is easy to manufacture and can be provided at low cost.
