Description

本考案は、金属板に貼り付けたシート用孔開け具、特に、パンチング孔の開いたアルミ板などの金属板に貼り付けられた反射シートなどのシート状の物に、該アルミ板に形成された孔に対応して、開口孔を開ける（くり抜く）ためのシート用孔開け具、及び、この孔開け具の位置決め具、及び、上記シート孔開け具と位置決め具とよりなるシート用孔開け装置に関するものである。 The present invention is formed on a sheet-like perforating tool for a sheet attached to a metal plate, particularly a sheet-like object such as a reflective sheet attached to a metal plate such as an aluminum plate having punching holes. A sheet-drilling tool for making (hollowing out) an opening hole corresponding to a hole, a positioning tool for the hole-drilling tool, and a sheet-drilling device including the sheet-drilling tool and the positioning tool. It is about.

道路標識板などは、アルミ板などの表面に、道路標示が表示された再帰性高角反射シートを貼り付け、夜間時においても、該再帰性高角反射シートをヘッドライトや投光器等で照らすことにより、適切な板面輝度を確保し、必要な道路標示を識別できるように形成されている。 For road sign boards, etc., a retroactive high-angle reflective sheet with road markings is attached to the surface of an aluminum plate, etc., and the retroactive high-angle reflective sheet is illuminated with a headlight, floodlight, etc. even at night. It is formed so that appropriate board brightness can be ensured and necessary road markings can be identified.

また、上記道路標識板に逆光対策がなされた逆光対策標識板においては、上記道路標識板の所望の箇所に、複数の貫通孔（パンチング孔等）加工がなされて、逆光時であっても、太陽光が上記孔を通過し、標示の判読に必要な板面輝度を確保している。 Further, in the backlight countermeasure sign board in which the road sign board is backlit, a plurality of through holes (punching holes, etc.) are processed in the desired portion of the road sign board, even when the road sign board is backlit. Sunlight passes through the hole to ensure the board surface brightness required for reading the sign.

この逆光対策標識板の製造方法においては、孔の開いていないアルミ板などの金属板に反射シートを貼り貼り付け、これを、ドリルで、反射シートと金属板とに孔開けをすると、反射シートに傷がついてしまう。そのため、実際には、予め金属板にドリルで孔を開け、この孔の開いた金属板に、孔の開いていない反射シートを接着等により貼り、その後に、この反射シートに、上記金属板の孔の位置に合わせて、専用のシート孔開け具を用いて、孔開けを行っている。 In the method of manufacturing this backlight countermeasure sign plate, a reflective sheet is attached to a metal plate such as an aluminum plate without holes, and this is drilled to make holes in the reflective sheet and the metal plate. Will be scratched. Therefore, in reality, a hole is drilled in the metal plate in advance, a reflective sheet having no hole is attached to the metal plate having the hole by adhesion or the like, and then the reflective sheet is attached to the metal plate. Holes are drilled using a special sheet metal drilling tool according to the position of the holes.

そして、従来においては、比較的硬いシートを、より円形に近い孔を開ける要求性から、図８に示すようなシート用孔開け具１を用いており、このシート用孔開け具１は、円柱状の孔開け具本体２の下端の外周縁が鋭利な刃３に形成され、図９に示すように、この円形状の刃３を用いて、孔４ａが形成されたアルミ板４に貼付された反射シート５をくり抜いて、該反射シート５に円形状の孔を形成していた。 Conventionally, a sheet punching tool 1 as shown in FIG. 8 has been used because of the requirement to make a hole closer to a circle in a relatively hard sheet, and the sheet drilling tool 1 is a circle. The outer peripheral edge of the lower end of the columnar drilling tool main body 2 is formed on a sharp blade 3, and as shown in FIG. 9, the circular blade 3 is used and attached to the aluminum plate 4 on which the hole 4a is formed. The reflective sheet 5 was hollowed out to form circular holes in the reflective sheet 5.

なお、上記金属板に接着させるシートとしては、例えば、キューブタイプやプリズムタイプなどの反射素子をライナーと透明プラスチックとで挟んで接着して形成した高輝度反射シートの他、合成樹脂製シートや、紙製シート、布製シート、これらを組み合わせた複合素材シートなど、金属板に接着可能なあらゆるシート状物が含まれる。 Examples of the sheet to be adhered to the metal plate include a high-brightness reflective sheet formed by sandwiching a reflective element such as a cube type or a prism type between a liner and a transparent plastic and adhering them, a synthetic resin sheet, and the like. It includes any sheet-like material that can be adhered to a metal plate, such as a paper sheet, a cloth sheet, and a composite material sheet that combines these.

しかしながら、上記孔開け具１の刃３は、シートくりぬき時、アルミ板４の孔４ａの縁にぶつからないようにするため、例えば、孔４ａの径が５ｍｍの場合、円形状の刃３の径を４．６ｍｍ程度と小さく形成する必要があり、孔の径に比べて刃の径を８％〜１０％程度小さく必要がある。 However, in order to prevent the blade 3 of the drilling tool 1 from colliding with the edge of the hole 4a of the aluminum plate 4 when the sheet is hollowed out, for example, when the diameter of the hole 4a is 5 mm, the diameter of the circular blade 3 is circular. It is necessary to form as small as about 4.6 mm, and the diameter of the blade needs to be about 8% to 10% smaller than the diameter of the hole.

このため、孔４ａに比べて、くり抜く孔が小さいため、くり抜かれていないシートが若干、孔４ａの内側にはみ出してしまい、そうすると、くり抜いた上記刃３を引き抜く際に、上記はみ出たシート部分が、摩擦により上方に引っ張られ、反射シートとアルミ板との接着部がはがれてしまう場合があった。 For this reason, since the hole to be hollowed out is smaller than that of the hole 4a, the sheet that has not been hollowed out slightly protrudes inside the hole 4a. Then, when the hollowed out blade 3 is pulled out, the sheet portion that protrudes is In some cases, the adhesive part between the reflective sheet and the aluminum plate was peeled off due to being pulled upward by friction.

また、従来においては、くり抜くために、上記孔開け具の設置位置の確認が必要で、手間がかかっていた。 Further, in the past, it was necessary to confirm the installation position of the drilling tool in order to hollow out, which was troublesome.

本考案は、上記の欠点を除くようにしたものである。 The present invention is designed to eliminate the above drawbacks.

（２．シート用孔開け具６の説明） (2. Explanation of sheet drilling tool 6)

本考案のシート用孔開け具６は、図１に示すように、円柱状の孔開け具本体８と、該本体８の下端に形成した円錐状の頭部９と、上記頭部９の上方の上記本体８に設けた、上記頭部９の上端の径よりも小さい径に形成された首部１０とよりなる。 As shown in FIG. 1, the sheet drilling tool 6 of the present invention includes a columnar drilling tool main body 8, a conical head 9 formed at the lower end of the main body 8, and an upper portion of the head 9. The neck portion 10 is provided on the main body 8 and has a diameter smaller than the diameter of the upper end of the head portion 9.

なお、図１に示すように、上記頭部９の上端と上記首部１０の下端と間に、該上端の径と同一径の円柱部分１１が形成されていてもよく、また、該円柱部分１１を省略し、上記頭部９の上端上に上記首部１０が形成されるようにしてもよい。 As shown in FIG. 1, a cylindrical portion 11 having the same diameter as the upper end may be formed between the upper end of the head 9 and the lower end of the neck portion 10, and the cylindrical portion 11 may be formed. May be omitted so that the neck portion 10 is formed on the upper end of the head portion 9.

そして、上記円錐状の頭部９の上端外周部分が切断刃１２に形成されるようになる。 Then, the outer peripheral portion of the upper end of the conical head 9 is formed on the cutting blade 12.

なお、上記円錐状の頭部９の上端の径は、アルミ板４に形成した孔４ａの径よりも若干、小さい径とすることができ、例えば、アルミ板の径が５ｍｍであれば、４．９ｍｍ程度まで大きく形成することができ、孔の径に比べて刃の径を、例えば、１％〜４％程度小さくする程度ですむようになる。 The diameter of the upper end of the conical head 9 can be slightly smaller than the diameter of the hole 4a formed in the aluminum plate 4. For example, if the diameter of the aluminum plate is 5 mm, 4 It can be formed as large as about 9.9 mm, and the diameter of the blade can be reduced by, for example, about 1% to 4% with respect to the diameter of the hole.

なお、上記首部１０は、設けなくてもよいが、切りくずを、該首部１０により形成される凹部に貯めることにより、目詰まりを防ぐことができるようになる。 Although the neck portion 10 does not have to be provided, clogging can be prevented by accumulating chips in the recess formed by the neck portion 10.

When the main body 8 is inserted, it is composed of a compression spring 16 such as a coil spring provided between the retaining portion 15 and the other plate body 14c in a compressed state.

そして、上記孔１４ｄから外部に突出した、上記孔開け具６の尾部６ｂを、上記バネ１６に抗して、頭部９側に押圧すれば、上記頭部９が、上記他方の板部１４ｃの孔１４ｅから外方に突出し、シートをくりぬけるようになる。 Then, when the tail portion 6b of the drilling tool 6 projecting outward from the hole 14d is pressed against the spring 16 toward the head portion 9, the head portion 9 is pressed against the other plate portion 14c. It protrudes outward from the hole 14e of the hole 14e, and the sheet can be hollowed out.

そして、尾部６ｂの押圧を解除すれば、上記頭部９が上記孔１４ｅ内に引っ込むようになる。 Then, when the pressure on the tail portion 6b is released, the head portion 9 is retracted into the hole 14e.

この連結孔開け具１３を用いれば、複数の孔開けを容易に行うことができるようになる。 By using this connecting hole drilling tool 13, a plurality of holes can be easily drilled.

（３．位置決め具） (3. Positioning tool)

The tool 7 can be positioned and fixed.

そして、位置決めされて固定された上記位置決め具７の孔１７ａを利用することにより、反射シート５を保護しつつ、上記アルミ板４の孔４ａに対応した、上記シート５の所望の位置に、連続して孔開け作業をすることができるようになる。 Then, by utilizing the hole 17a of the positioning tool 7 that has been positioned and fixed, the reflective sheet 5 is protected and continuously located at a desired position of the sheet 5 corresponding to the hole 4a of the aluminum plate 4. Then you will be able to make holes.

なお、図６に示すように、複数の位置決め具７を組み合わせて使用してもよい。 As shown in FIG. 6, a plurality of positioning tools 7 may be used in combination.

この場合、例えば、上記位置決め具７のガイド用板を矩形状に形成した場合、一方の辺と、対向する他方の辺とがそれぞれ篏合可能な波状又はノコギリ歯状又はこれらの組み合わせに形成することにより、同一形状に形成された複数の位置決め具７を用いて、より広範囲において使用できるようになる。 In this case, for example, when the guide plate of the positioning tool 7 is formed in a rectangular shape, one side and the other side facing each other are formed in a wavy shape, a sawtooth shape, or a combination thereof. As a result, a plurality of positioning tools 7 formed in the same shape can be used in a wider range.
