この考案はくぎ、特に打ち込み使用時の保持力
に優れたくぎに関する。[Detailed Description of the Invention] This invention relates to nails, particularly nails that have excellent holding power during driving.
近時、建材として不燃性のサイデイングボー

く用いられるようになつてくるにつれて、このよ
うな非繊維質の対象物に打ち込み使用しても充分

されている。 In recent years, non-fibrous materials such as non-combustible siding boards and particle boards have come to be used more and more as building materials. There is a strong demand for the emergence of a nail that can be obtained by exerting power.

という欠点のあることが知見された。 Conventionally, as a type of nail used for such objects, as shown in FIG. Holding force reinforcement part 14,1
4,... are provided at predetermined intervals. However, although this conventional product has slightly better holding power than ordinary nails with straight leg shafts, the height of the radial protrusions 13, 13, . . . of each reinforcing portion 14, 14, . are all equal and lined up in a straight line in the axial direction, so
When driving this into a building material, etc., the hole formed by the lower holding force reinforcement part 14,
The next retaining force reinforcing section 14 having the same shape only enters one after another, and therefore the open hole into which the upper retaining force reinforcing section finally enters is loose, and it is difficult to penetrate from the surroundings. The fastening force of
It has been found that there is a drawback in that almost no tightening force is applied, and therefore it is still not possible to obtain a sufficient effect of increasing the holding force.
この考案は、かかる知見に基づき、その改善に
より保持力の更に一層顕著に増大せられたくぎを
提供しようとするものである。 This invention is based on this knowledge and aims to provide a nail whose holding power is even more significantly increased by improving the knowledge.
以下、この考案の構成を第１図ないし第８図に
示す実施例について説明する。 The configuration of this invention will be described below with reference to embodiments shown in FIGS. 1 to 8.

3 is a head, and 3 is a sharp tip at the lower end. On the outer circumferential surface of the leg shaft 1, there are a plurality of, especially several or more, holding force reinforcing parts 4, 4 of a predetermined length at predetermined intervals in the vertical direction.
...is provided. Each of these holding force reinforcement parts 4 is
Both have a large number of radial protrusions 5, 5, . . . formed on the circumferential surface that are long in the axial direction.

る。 These radial protrusions 5 all have a triangular cross section, and are arranged in a straight line parallel to the axis with the same number of radial protrusions in each of the holding force reinforcement parts 4, 4, . . . However, the heights of the cross-sectional shapes are made to vary sequentially. That is, the individual holding force reinforcement parts 4 shown in FIGS. 3 to 8 (excluding FIG. 4),
As is clear from the comparison of the cross-sectional shapes of 4, . The height of the cross-sectional shape of the radial protrusions 5, 5, . . . is high. That is, the degree of outward protrusion is gradually increased. Therefore, the apex angles of the radial protrusions 5, 5, ... of each of the holding force reinforcement parts 4, 4, ... gradually become smaller from the lower ones to the upper ones, and the apexes are connected. The diameter of the circle is said to gradually increase.
なお、放射状突条５の断面形状は、図示のよう

る顕著な効果がある。 Since this device has the above-mentioned configuration, when it is driven into the building material A etc., the holding force reinforcement of the next higher level is inserted into the open hole formed by the lowest holding force strengthening part 4 following the sharp tip part 3. When the part 4 enters, the above-mentioned perforation is further pushed and expanded due to the difference in height of the radial protrusions 5, 5, . . . . Then, the upper holding force strengthening parts 4,
4,... are driven into the building material A etc. with the forcible expansion action of the open hole, so in the driving state, all of the holding force reinforcement parts are strongly tightened from the surroundings and are driven into the building material A etc. It is held tightly inside. Moreover, during the typing process,
Rather than creating a large open hole from the beginning using the lowermost holding force strengthening section 4, the open hole is initially made relatively small and is gradually enlarged by the upper holding force strengthening section. Therefore, even if it is driven into a non-fibrous, comparatively fragile object such as a building material, there is little risk of major destruction of the tissue around the driven part, and each of the above-mentioned holding force reinforcement parts has a good solidity. Coupled with the binding action, this has the remarkable effect of ensuring that the nail is kept securely in place and exhibiting excellent holding power.
