Description
【考案の詳細な説明】 ＜産業上の利用分野＞ 本考案は、隠しねじ釘に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a hidden screw nail.
＜従来の技術＞ 従来、釘着手段を隠して、二つの部材を釘着させる手段
に隠し釘が用いられていた。隠し釘は、両端を尖鋭にし
棒状体から成っている。又、釘着をより強固にする為
に、隠し釘の外周面には、周方向に沿って溝を形成した
ものや、螺線状に溝を形成したものがあった。<Prior Art> Conventionally, a hidden nail has been used as a means for concealing a nailing means and nailing two members together. The hidden nail is made of a rod with sharp ends. Further, in order to make the nailing more firm, there have been ones in which a groove is formed along the circumferential direction on the outer peripheral surface of the hidden nail, and a groove is formed in a spiral shape.
＜考案が解決しようとする課題＞ 従来の隠し釘では、 隠し釘を打ち込むとき、金槌等の工具が必要である。<Problems to be solved by the invention> Conventional hidden nails require a tool such as a hammer to drive the hidden nails.
被固着部材に打ち込まれた隠し釘に固着部材を打ち付
けたときに、隠し釘の先端が被固着部材から突き出し易
い。When the fixing member is driven onto the hidden nail that has been driven into the member to be fixed, the tip of the hidden nail easily protrudes from the member to be fixed.
外周面に溝が形成されたものであっても、強固な固着
が行われない。Even if a groove is formed on the outer peripheral surface, firm fixation is not achieved.
隠し釘の両端が尖鋭に成っている為に、手等を引っ掛
けて怪我をする危険性が高い。Because both ends of the hidden nail are sharp, there is a high risk of catching your hand and injuring yourself.
等の課題を有していた。Had problems such as.
＜課題を解決するための手段＞ 本考案は、上記課題を解決する為に成されたもので、締
着力の強い隠しねじ釘を提供することを目的とするもの
である。<Means for Solving the Problems> The present invention has been made to solve the above problems, and an object thereof is to provide a hidden screw nail having a strong fastening force.
即ち、ねじ部と、ねじ頭とから成り、前記ねじ部は、頭
部に締付け穴が形成され、先端部が尖鋭に形成されてい
て、外周面にねじ山が設けられているとともに、前記ね
じ部の頭部に円筒状のねじ頭を設け、その外周面に、前
記ねじ部に設けたねじ山の巻き方向に対して逆の巻き方
向にねじ山が設けられていて、ねじ頭の開口部を鋭利に
形成したことを特徴とするものである。That is, it is composed of a screw portion and a screw head, and the screw portion has a tightening hole formed in the head portion, a sharpened tip portion, and a screw thread provided on the outer peripheral surface thereof. A cylindrical screw head is provided on the head of the portion, and a screw thread is provided on the outer peripheral surface in a winding direction opposite to the winding direction of the screw thread provided on the screw portion, and an opening of the screw head is formed. Is characterized by being sharply formed.
＜作用＞ 上記構成の隠しねじ釘は、 締付け穴を設けたことにより、ドライバーを用いて被
固着部材にねじ込める。<Operation> Since the concealed screw nail having the above-described configuration is provided with the tightening hole, the concealed screw nail can be screwed into the adhered member using the driver.
ねじ部に設けたねじ山の巻き方向に対して逆の巻き方
向のねじ山をねじ頭に設けたことにより、ねじ部が被固
着部材にねじ込まれて、ねじ頭が固着部材に打ち込まれ
るとき、ねじ頭のねじ山に加わる押圧力によって、ねじ
部が被固着部材に一層ねじ込まれる方向に回転する。そ
の回転方向はねじ頭が固着部材にねじ込まれる方向にも
一致しているので、ねじ頭は固着部材に一層ねじ込まれ
る。When the screw head is provided with a screw thread having a winding direction opposite to the winding direction of the screw thread provided on the screw portion, the screw portion is screwed into the member to be fixed, and the screw head is driven into the fixing member, The pressing force applied to the threads of the screw head causes the screw portion to rotate in a direction in which it is further screwed into the adhered member. The direction of rotation also coincides with the direction in which the screw head is screwed into the fixing member, so that the screw head is screwed further into the fixing member.
よって、被固着部材と固着部材との固着が強固なものに
なる。Therefore, the adherence between the adhered member and the adhered member becomes strong.
ねじ頭を円筒状に形成し、而も開口部を鋭利に形成し
たことにより、固着部材に円滑に打ち込める。更に、ね
じ頭を円筒状に形成したことにより、ねじ頭の外周面と
内周面とが固着部材に接触する為に、固着力がより一層
強固なものになる。Since the screw head is formed in a cylindrical shape and the opening is sharply formed, it can be smoothly driven into the fixing member. Further, by forming the screw head in a cylindrical shape, the outer peripheral surface and the inner peripheral surface of the screw head contact the fixing member, so that the fixing force is further strengthened.
＜実施例＞ 本考案の実施例を図により説明する。<Embodiment> An embodiment of the present invention will be described with reference to the drawings.
第１図（ａ），（ｂ）に示す隠しねじ釘１は、ねじ部２
と、ねじ部２の頭部2aに設けた円筒状のねじ頭３とから
成る。The hidden screw nail 1 shown in FIGS.
And a cylindrical screw head 3 provided on the head 2a of the screw portion 2.
前記ねじ部２は、頭部2aに締付け穴４が形成されてい
