を具備する頭部とを有するドリルスクリューに関する。[Detailed Description of the Invention] The present invention includes a threaded ram portion with threads of substantially uniform outer diameter, root diameter, and pitch, and a threaded ram portion that is connected to the threaded ram portion and has an outer diameter that gradually becomes thinner. A tapered threaded portion with a beveled thread, a drill tip disposed at the tip of the tapered threaded portion, and a head integrally formed at the opposite end of the threaded stem portion and provided with a rotary tool engagement means. The present invention relates to a drill screw having a part.
ドリルスクリューは、例えば建築構造物において、鉄骨
や形鋼で構戊された枠組に他の部材特を取付ける際に、
下孔あけやタップ立でのような準備作業を要せず、単一
の作業で能率的に旋工出来るので、近年急速に普及しつ
つある。Drill screws are used, for example, in building structures, when attaching other parts to a framework made of steel or shaped steel.
It has become rapidly popular in recent years because it does not require preparatory work such as drilling pilot holes or tapping, and can be turned efficiently in a single operation.
元来ドリルスクリューは、タツピンねじの先端にドリル
チップを１体的に形或したものなので、通常のタツピン
ねじとして必要な長さよりもドリルチップの部分だけ長
くなり、従って締付後鉄骨や形鋼の裏側に鋭利なドリル
チップが突き出ることになる。Originally, a drill screw has a drill tip integrally formed at the tip of a tatsupin screw, so the length of the drill tip is longer than the length required for a normal tatsupin screw, so it cannot be used on steel frames or shaped steel after tightening. A sharp drill tip will protrude from the back side.
この突き出た部分は、多くの場合壁の内側、屋根裏、天
井裏あるいは床下であり、しかもチャンネル内に納まっ
ているので、このようなドリルチップの突き出しが邪魔
になることはないが、使用個所によってはこれが危険と
なる場合も少なくない。This protruding part is often located inside a wall, in an attic, attic, or under a floor, and is contained within a channel, so the protrusion of the drill tip does not get in the way, but depending on the location where it is used, This is often dangerous.
特に建築以外の使用の場合、例えば自動車、家庭電気製
品等では、上述のようなドリルチップの突き出しが許さ
れない場合の方が多い。Particularly in applications other than construction, such as automobiles, home appliances, etc., protrusion of the drill tip as described above is often not allowed.
換言すれば、ドリルチップの突き出しが生ずるために、
これらの製品分野におけるドリルスクリューの普及が妨
げられていると言わねばならない。In other words, due to the protrusion of the drill tip,
It must be said that the widespread use of drill screws in these product areas has been hindered.
本考案の目的は、従来のドリルスクリューにおける上述
の欠点を除去し、ドリルスクリューの締付後ドリルチッ
プを除去し、通常のタツピンねしもしくは小ねじと同じ
ような締付状態を達或することである。The purpose of the present invention is to eliminate the above-mentioned drawbacks of conventional drill screws, remove the drill tip after tightening the drill screw, and achieve a tightening condition similar to that of a normal tutpin screw or machine screw. It is.
以下に添附の図面について、従来のドリルスクリューお
よび本考案によるドリルスクリューを説明する。BRIEF DESCRIPTION OF THE DRAWINGS A conventional drill screw and a drill screw according to the present invention will be described below with reference to the accompanying drawings.
第１図は、従来のドリルスクリューを用いて、締付部材
７に被締付部材８を締付固着した状態を示す。FIG. 1 shows a state in which a member to be tightened 8 is fastened and fixed to a tightening member 7 using a conventional drill screw.
ドリルスクリュー１はねじ杆部２、テーパーねじ部３、
ドリルチツプ４およびねじ杆部２の他端に１体的に形威
した頭部５を有する。The drill screw 1 has a threaded rod portion 2, a tapered threaded portion 3,
The drill tip 4 and the other end of the threaded rod portion 2 have a head 5 integrally formed therein.
頭部５には回転工具係合手段、例えば十字穴６が設けら
れている。The head 5 is provided with rotary tool engaging means, for example a cross recess 6.
この場合、充分な締付力を得るには、ねじ杆部２のねし
山が締付部材７の厚さ全体に亘って充分に嵌合している
ことが必要であり、そのためねじ杆部の長さは少くとも
両部材７および８の厚さの和だけなければならない。In this case, in order to obtain sufficient tightening force, it is necessary that the threads of the threaded rod portion 2 are fully fitted over the entire thickness of the tightening member 7; The length must be at least the sum of the thicknesses of both members 7 and 8.
従って、締付部材７の裏側にはテーパーねじ部３とドリ
ルチップ４とがすべて突き出していることになる。Therefore, the tapered threaded portion 3 and the drill tip 4 all protrude from the back side of the tightening member 7.
通常のタツピンねしは、テーパーねじ部３のみが突き出
せば充分であるのに比べると、ドリルスクリューでは更
にその先に鋭利なドリルチップが付加されて突き出てい
るので、外観が悪くかつ非常に危険である。With a normal tatsupin screw, it is enough for only the tapered threaded part 3 to protrude, but with a drill screw, a sharp drill tip is added to the tip and protrudes, making it look bad and very dangerous. It is.

る。The drill screw 11 according to the invention shown in FIGS. 2 and 3 has a substantially uniform outside diameter, as in the conventional one.
A threaded threaded portion 12 having a thread with a root diameter and a pitch, a tapered threaded portion 13 connected to this threaded threaded portion and provided with a threaded thread whose outer diameter gradually becomes smaller, It has a drill tip 14 at its end and a threaded ram 12.
At the opposite end, a head 15 is integrally formed, and this head is provided with rotary tool engagement means, for example a cross recess 20.
更にドリルスクリュー１１は、テーパーねじ部１３とド
リルチツプ１４との間に本考案により形或した環状溝１
６が刻設されている。Furthermore, the drill screw 11 has an annular groove 1 formed according to the present invention between the tapered threaded portion 13 and the drill tip 14.
6 is engraved.
本考案によるドリルスクリューは、第４図に示すごとく
締付部材７と被締付部材８とにねじ込んで締付けた後、
ペンチやハンマー等の工具で叩くことにより溝１６より
折れ、それによってドリルチツプ１４を除去することが
出来る。The drill screw according to the present invention is screwed into the tightening member 7 and the member to be tightened 8 as shown in FIG.
By hitting it with a tool such as pliers or a hammer, it breaks from the groove 16, thereby allowing the drill tip 14 to be removed.
かくして、図示のように、通常のタツピンねじと同様な
締付状態が得られる。Thus, as shown in the figure, a tightening condition similar to that of a normal tuft pin screw can be obtained.
溝１６は、環状のものに限らず、ドリルチップの折り取
りの目的に適する他の如何なる凹部も用いることが出来
る。The groove 16 is not limited to an annular groove, but any other recess suitable for the purpose of breaking off the drill tip can be used.
例えば、第５図および第６図に示すように互に平行な２
条の弦状溝１７を設けることも可能である。For example, as shown in FIGS. 5 and 6, two parallel
It is also possible to provide chordal grooves 17 in strips.
このような凹部は、上述のように、テーパーねじ部１３
とドリルチツプ１４との間に設けるのみならず、第７図
に示すように、環状溝１６をねじ杆部１２とテーパーね
じ部１３との間に設けることも出来る。Such a concave portion is formed by the tapered threaded portion 13 as described above.
In addition to being provided between the drill tip 14 and the drill tip 14, an annular groove 16 can also be provided between the threaded rod portion 12 and the tapered threaded portion 13, as shown in FIG.
このときは、締付後ドリルチツプ１４およびテーパーね
じ部１３を折り取ることになるので、締付部材の裏側へ
の突き出し部分は更に短かくなり、更に有利な効果が得
られる。At this time, since the drill tip 14 and the tapered threaded portion 13 are broken off after tightening, the portion of the tightening member protruding toward the back side becomes even shorter, and a more advantageous effect can be obtained.
上述のように、本考案によるドリルスクリューは締付後
その先端を折り取ることが出来るので、危険防止に有効
でありかつ締付後の外観の向上を来たす特長が得られる
。As described above, the tip of the drill screw according to the present invention can be broken off after being tightened, so that it is effective in preventing danger and improves the appearance after tightening.
又、ドリルチップの外径は通常ねじ杆部１２の有効径に
は・゛近い太さを有するので、突き出し部分にナットを
嵌拝することは不可能であるが、本考案によりドリルチ
ップを折り取ることによりナットの嵌挿が可能となる。In addition, since the outside diameter of the drill tip is normally close to the effective diameter of the threaded rod portion 12, it is impossible to fit a nut into the protruding portion, but with the present invention, the drill tip can be bent. By removing it, the nut can be inserted.
従って、第８図に示すように、締付部材７の裏側になお
残っているねじ部にナット１８を嵌挿し、別の部材又は
部品１９を固着することが可能となる。Therefore, as shown in FIG. 8, it is possible to fit the nut 18 into the threaded portion still remaining on the back side of the tightening member 7 and to fix another member or component 19.
このように、本考案によりドリルスクリューの応用範囲
が更に拡大される。Thus, the present invention further expands the range of applications of the drill screw.
