Abstract

To provide a corner cutter which can be used even in a curved wall surface in a wall surface end part and a cutting finish of a floor sheet.SOLUTION: A semi-columnar guide is provided in an end of a body, and a gap is provided in the center of the guide for protruding an edge.

Description

この発明は湾曲した壁面でも、端から端まで床シートの切り込み仕上げ施工ができるナイフ形状の持ち運びが便利なコーナーカッターである。The present invention is a knife-shaped corner cutter that is convenient to carry and can cut and finish a floor sheet from end to end even on a curved wall surface.

従来の床シートのコーナーカッターは、壁面に沿わせるガイド面と床面に沿って摺動する底面となる土台とそのガイド面と底面をつなぐ曲面を有している。前記、ガイド及び土台に対して前後又は上下に刃を移動し固定する。この様にガイドと土台と刃の位置関係によりシートの切れる長さを定め、床面から壁面へ緩やかに折り曲げたシートの上からコーナーカッターを押し当て切断施工する。通常、壁面と床面の交わる所へ切ったシートの端部が丁度の長さになるようにするが、あくまでガイド面が沿うのは壁面と床面の交点ではなく、前記交点の上1~2cmの所となる。その為壁の傾斜が変化するとシートの切断される位置がずれてしまう。(図3)及び(図4)A conventional floor sheet corner cutter has a guide surface along the wall surface, a base that serves as a bottom surface that slides along the floor surface, and a curved surface that connects the guide surface and the bottom surface. The blade is moved back and forth or up and down with respect to the guide and base and fixed. In this way, the length of the sheet to be cut is determined by the positional relationship between the guide, the base, and the blade, and the corner cutter is pressed onto the sheet gently folded from the floor surface to the wall surface to perform cutting. Normally, the edge of the sheet cut to the intersection of the wall surface and the floor surface is exactly the length. 2 cm. Therefore, if the inclination of the wall changes, the position where the sheet is cut will shift. (Fig. 3) and (Fig. 4)

特開昭50-95900Japanese Patent Laid-Open No. 50-95900

これは次のような欠点があった。従来のコーナーカッターは壁面が湾曲せず真っ直ぐかつ垂直である事が変化しない事を前提に作られている。しかし現場での施工ではトイレ便器の台座のように楕円であったり、波型にデザインされた壁も有り湾曲の度合いが変化する事もある。その他シートを切り合わせる対象物は垂直になっていない事もある。例えば階段の蹴込みは一般的に手前に傾斜しているが、左官仕上げの蹴込みの傾斜角度は階段一段の右と左でも大きく異なる。このように壁面の変化に従来のコーナーカッターは対応できない為、丁度の長さにシートを切り進む事ができない。本発明は以上のような欠点をなくす為になされたものである。This had the following drawbacks. Conventional corner cutters are made on the premise that the walls are straight and vertical without bending. However, in construction at the site, there are elliptical walls like the pedestal of a toilet bowl, and there are walls designed in a wave shape, and the degree of curvature may change. In addition, the object to be cut with the sheet may not be vertical. For example, the riser of a staircase is generally inclined toward the front, but the angle of inclination of the plastered riser differs greatly between the right and left sides of a single step. Since the conventional corner cutter cannot cope with such changes in the wall surface, it is impossible to cut the sheet to the exact length. SUMMARY OF THE INVENTION The present invention has been made to eliminate the drawbacks as described above.

本体の柄となる部分の内部に刃を収納し、柄の端部に半円柱状のシートを押えて曲げるガイドを設ける。ガイドの半円柱の円弧の中央部分より刃を突出させネジで固定する。刃に対してガイドが左右対称となるようにしてやり、そのガイドの両側面にメモリを設ける。The blade is housed inside the handle portion of the main body, and a guide for pressing and bending a semi-cylindrical sheet is provided at the end of the handle. The blade protrudes from the center of the arc of the semi-cylindrical guide and is fixed with a screw. The guide is symmetrical with respect to the blade, and memory is provided on both sides of the guide.

本体の柄の内部より突出させる刃を半円柱状の円弧の中央より出す事で、左右どちらからでも端から端までシートを切る事ができる。又、半円柱状のガイドはシートに押しつけて切断している最中でも本体の傾きを変え壁面と刃の角度を変えてやる事でシートの切れる長さを自由に変える事ができる。これにより傾斜角度の変化する壁や湾曲する壁などもシート切断中に切る長さを微調整できる。ガイドの両側に設けたメモリにより、刃の入る角度、すなわちシートの切れる長さがわかるので微調整しやすい。又、本体の形状をナイフ型にした事で、本発明品のみで壁面入り角のシートの角きめから、コーナーカットの仕上げまで他のカッターナイフなどに持ち替える事なく施工できる。これにより作業時間も短縮できる。そして従来の物に比べカッターホルダーに入れる事が出来るので持ち運びも大変しやすくなる。By protruding the blade protruding from the inside of the handle of the main body from the center of the semi-cylindrical arc, it is possible to cut the sheet from end to end from either the left or right. In addition, even when the semi-cylindrical guide is pressed against the sheet and cut, the length of the sheet to be cut can be freely changed by changing the inclination of the main body and changing the angle between the wall surface and the blade. As a result, it is possible to finely adjust the length to be cut during sheet cutting even for a wall whose inclination angle changes or a curved wall. With the memory provided on both sides of the guide, it is easy to make fine adjustments because the angle at which the blade enters, that is, the length of the sheet to be cut can be known. Also, by making the shape of the main body into a knife shape, it is possible to work from the corner texture of the sheet at the corner of the wall surface to the finish of the corner cut without switching to another cutter knife or the like. This also shortens the working time. And since it can be put in a cutter holder compared to conventional ones, it is very easy to carry.

以下、図面を参照しながら本発明を実施する為の形態について説明する。なお、本明細書及び図面においては、同一の符号が付された構成要素は実質的に同一の構造または機能を有するものである。EMBODIMENT OF THE INVENTION Hereinafter, the form for implementing this invention is demonstrated, referring drawings. In this specification and drawings, constituent elements with the same reference numerals have substantially the same structure or function.

図1は本発明にかかる曲線の切れるコーナーカッターの一例として構成を示す斜視図である。1は本体を構成するグリップ部分で内側にカッター刃を収納できる。FIG. 1 is a perspective view showing a configuration as an example of a corner cutter capable of cutting curved lines according to the present invention. 1 is a grip part that constitutes the main body, and a cutter blade can be stored inside.

2は主要部分となる半円柱状のスライディングベース2で、円弧の中央より刃3の先端を突出できる隙間を設ける。刃3を中央としスライディングベース2を左右対称の形状にする事で、左右どちらの方向にもシートを切り進める事ができる。Reference numeral 2 denotes a semi-cylindrical sliding base 2, which is the main part, and has a gap that allows the tip of the blade 3 to protrude from the center of the arc. By making the sliding base 2 symmetrical with the blade 3 at the center, the sheet can be cut in either the left or right direction.

スライディングベースの側面にメモリ4を付けてシート切断施工時、壁面側シートにどのメモリ4が接触しているかを目視する事で刃3がシートに入る切断角度、すなわちシートの切れる長さがわかる。When the memory 4 is attached to the side surface of the sliding base and the sheet is cut, the cutting angle at which the blade 3 enters the sheet, that is, the cut length of the sheet can be known by visually checking which memory 4 is in contact with the sheet on the wall surface side.

本体を1より突出させた刃3は止めネジ5により固定する。ネジ5により固定する事で刃3の突出させる長さを無段階で調整できる。2個の止めねじ5を使用する事で刃3をしっかり固定できる。A blade 3 projecting from the main body 1 is fixed by a set screw 5. - 特許庁By fixing with a screw 5, the protruding length of the blade 3 can be adjusted steplessly. By using two setscrews 5, the blade 3 can be firmly fixed.

以上図面を参照しながら本発明の好適な実施形態について説明したが本発明は上述した形態に限定されない。すなわち、特許請求の範囲に記載された発明の範囲以内で当業者が想到し得る形態または各種の変更例についても本発明の技術的範囲に属するものと理解される。Although the preferred embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to the above-described forms. In other words, it is understood that forms or various modifications that can be conceived by those skilled in the art within the scope of the invention described in the claims also belong to the technical scope of the present invention.
