Description

【0001】
【発明の属する技術分野】
本発明は、グラスウール、フェルト、スポンジ等の柔らかい素材の円形穴明けに使用する、穴明け道具に関するものである。
【0002】
【従来の技術】
従来、グラスウール、フェルト、スポンジ等の柔らかい素材へ円形の穴明けをするときは、切り刃を当てて穴明けしていたが、素材が柔らかいために周りの素材を引っ張ってきて、うまく穴明けができず、素材を損傷することが多かった。
【0003】
【発明が解決しようとする課題】
従来、グラスウール、フェルト、スポンジ等の柔らかい素材へ円形の穴明けをするとき、切り刃を直接当てて穴明けすると、周りの素材を引っ張ってきて、うまく穴明けができず、素材を損傷することが多かった。例えば、壁に穴を明けてエアコンを取り付けるとき、外壁と内壁の間に断熱材として両側をアルミ箔で被覆したグラスウールが使われていることがある。このグラスウールに穴を明けるのに直接切り刃を当てて穴明けすると、周りのアルミ箔やグラスウールを引っ張って来て、断熱材を損傷してしまう。
本発明は、この課題を解決するためになされたものである。
【0004】
【課題を解決するための手段】
外パイプ(1)にツバ(1a)及びギザ(1b)を設ける。内パイプ(2)にキャップ(3)を取り付け、その反対側の内側に切り刃取付パイプ(4)を緊結し、該切り刃取付パイプ(4)の円周上に切り刃(5)を巻き付けて固定テープ(6)により固定する。外パイプ(1)に内パイプ(2)をスライド及び回転自在に嵌合する。
【0005】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
外パイプ(1)にツバ(1a)及びギザ(1b)を設ける。ギザ(1b)は、先端の尖った形がよい。
内パイプ(2)にキャップ(3)を取り付け、その反対側の内側に切り刃取付パイプ(4)を緊結する。切り刃取付パイプ(4)の円周上に切り刃(5)を、切り刃の先端が出るように取り付け、固定テープ(6)を巻いて固定する。
外パイプ(1)に内パイプ(2)をスライド及び回転自在に嵌合する。
【0006】
内パイプ(2)に取り付けるキャップ(3)は緊結の嵌め込み式としてもよいが、ネジ込み式とした方が切り取った素材のカスを取り除くのに便利である。
また、切り刃取付パイプ(4)は、内パイプ(2)に緊結できる径とし、さらに接着剤にて固定する。
【0007】
切り刃(5)は、切り刃取付パイプ(4)の円周上に切り刃の先端が1mmから2mm出るように取り付ける。切り刃(5)の形は、図3のAからEに示すようないろいろな形が考えられる。
切り刃(5)を切り刃取付パイプ(4)に固定する方法は、固定テープ(6)を巻く方法の外に、接着剤で固定する方法も考えられる。
【0008】
外パイプ(1)、内パイプ(2)、キャップ(3)及び切り刃取付パイプ(4)の材質は金属製等でもよいが、ビニールパイプ等のプラスチックパイプを使うと種類も豊富でコストも安く出来る。
【0009】
本発明は、例えばエアコン取り付け時に外壁あるいは内壁に穴を明けると、その中にアルミ箔で被覆されたグラスウールの断熱材があるので、これに穴を明けるときに使用する。
まず、外パイプ(1)を持って断熱材に押し当て、次に内パイプ(2)の切り刃(5)を断熱材に押し当て、内パイプ(2)を手で押し回していくと、切り刃(5)の円の大きさの穴がきれいに明く。これは外パイプ(1)のギザ(1b)によって断熱材がしっかりと押えられ、周りの断熱材が引っ張られることがないからである。
【0010】
本発明は、上記のような断熱材だけではなく、フェルト、発泡材、スポンジ等の柔らかい素材の円形穴明けに使用できる。また、布や不織布にも外パイプのギザや切り刃の形を工夫することによって使用することが可能である。
【0011】
【発明の効果】
本発明を使用することにより、グラスウール、フェルト、発泡材、スポンジ、布等柔らかい素材の円形穴明けが、きれいに簡単に出来る。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drilling tool used for circular drilling of soft materials such as glass wool, felt, and sponge.
[0002]
[Prior art]
Conventionally, when making a circular hole in a soft material such as glass wool, felt, sponge, etc., drilling was done by hitting a cutting blade, but since the material is soft, pull the surrounding material and make it well. In most cases, the material was damaged.
[0003]
[Problems to be solved by the invention]
Conventionally, when making a circular hole in a soft material such as glass wool, felt, sponge, etc., if you directly hit the cutting blade and drill, the surrounding material will be pulled and the hole will not be drilled well, damaging the material There were many. For example, when attaching an air conditioner to a wall, a glass wool whose both sides are covered with aluminum foil may be used as a heat insulating material between an outer wall and an inner wall. If a hole is cut directly into the glass wool by using a cutting blade, the surrounding aluminum foil or glass wool will be pulled and the insulation will be damaged.
The present invention has been made to solve this problem.
[0004]
[Means for Solving the Problems]
The outer pipe (1) is provided with a collar (1a) and a knurl (1b). A cap (3) is attached to the inner pipe (2), a cutting blade mounting pipe (4) is tightened on the inside on the opposite side, and a cutting blade (5) is wound around the circumference of the cutting blade mounting pipe (4). And fix with a fixing tape (6). The inner pipe (2) is slidably and rotatably fitted to the outer pipe (1).
[0005]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described.
The outer pipe (1) is provided with a collar (1a) and a knurl (1b). The indentation (1b) preferably has a pointed tip.
A cap (3) is attached to the inner pipe (2), and a cutting blade mounting pipe (4) is tightened on the inside on the opposite side. A cutting blade (5) is mounted on the circumference of the cutting blade mounting pipe (4) so that the tip of the cutting blade comes out, and is fixed by winding a fixing tape (6).
The inner pipe (2) is slidably and rotatably fitted to the outer pipe (1).
[0006]
The cap (3) to be attached to the inner pipe (2) may be of a tightly fitting type, but a screw-in type is more convenient for removing scraps of the cut material.
The cutting blade mounting pipe (4) has a diameter capable of being tightly connected to the inner pipe (2), and is fixed with an adhesive.
[0007]
The cutting blade (5) is attached so that the tip of the cutting blade protrudes from 1 mm to 2 mm on the circumference of the cutting blade mounting pipe (4). As the shape of the cutting blade (5), various shapes as shown in FIGS.
As a method of fixing the cutting blade (5) to the cutting blade mounting pipe (4), a method of fixing with an adhesive may be considered in addition to the method of winding the fixing tape (6).
[0008]
The material of the outer pipe (1), the inner pipe (2), the cap (3) and the cutting blade mounting pipe (4) may be made of metal or the like, but if plastic pipes such as vinyl pipes are used, the types are abundant and the cost is low. I can do it.
[0009]
In the present invention, for example, when a hole is formed in an outer wall or an inner wall when an air conditioner is attached, a glass wool heat insulating material covered with an aluminum foil is provided therein, and the present invention is used when the hole is formed.
First, hold the outer pipe (1) against the heat insulating material, then press the cutting edge (5) of the inner pipe (2) against the heat insulating material, and turn the inner pipe (2) by hand. The hole of the size of the circle of the cutting blade (5) is clear and clear. This is because the heat insulating material is firmly pressed by the indentation (1b) of the outer pipe (1), and the surrounding heat insulating material is not pulled.
[0010]
The present invention can be used for circular drilling of soft materials such as felts, foams, sponges, etc. as well as the above-mentioned heat insulating materials. It is also possible to use the cloth or nonwoven fabric by devising the shape of the knurls or cutting edges of the outer pipe.
[0011]
【The invention's effect】
By using the present invention, a circular hole made of a soft material such as glass wool, felt, foam material, sponge, cloth, etc. can be cleanly and easily made.
