Abstract

<P>PROBLEM TO BE SOLVED: To provide a blade having an angle measuring section, which solves the conventional problem, wherein respective protractor blade and angle-measuring blade relating to an angle measuring tool can not accommodate to changes in valley depth and ridge height of a V-shaped groove in its changing situation being produced by forming/grinding, machining and bending works because of their fixed sizes, in order to break down the fixed concept of angle measuring tool and realize a variable angle measurement. <P>SOLUTION: A slide opening 7 is formed at the center section of the angle-measuring blade 6 which is made up of two parallel linear sides 8, so as to be along the straight sides 8, and a straight-measure scale 5 is disposed on one straight side 8, and the whole surface of the other straight side 8 is adopted as the angle-measuring section 4. Movement operations are carried out in the length range of the slide opening 7 of the blade 6, such that the intersecting point of the center section (a) of the protractor becomes the standard, thereby expanding the variable angle and the measurement width of straight measure. In addition, respective lengths of the angle-measuring section 4 and the slide opening 7 are made proportional according to the length of the angle-measuring blade 6. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、分度器の、山谷の変化に対応する分度器の、角度測定ブレ−ドの形成。 The present invention is the formation of an angle measuring blade of a protractor corresponding to a change in a mountain and valley of the protractor.

実用新案公報平４−１６３０３文献によると、直尺１２の指示部１２ｄと、スライド孔１２ａのバランスについては、スライド孔１２ａの中心部の延長線上に指示部１２ｄがあるため、スライド孔１２ａの長さは、ネジ１３と目盛り１１ｃの間に限定され、指示部１２ａの長さもそれに付随するものであり、伸縮するスライド孔の長さも非常に制限されるものであり、よって、測定の範囲も制限されたものであるものと理解する。
実開平４−１６３０３号公報 According to Japanese Utility Model Publication No. Hei 4-16303, the balance between the direct 12 and the slide hole 12a is indicated by the indicator 12d on the extension of the center of the slide hole 12a. The length is limited between the screw 13 and the scale 11c, and the length of the indicator 12a is accompanied by it, and the length of the slide hole that expands and contracts is very limited, and therefore the range of measurement is also limited. It is understood that it was done.

実用新案公報 平４−１６３０３文献による、スライド溝１２ａと指示部１２ｄの合計の長さは、円弧辺の半径以内で設定する必要があり、スライド溝１２ａと指示部１２ｄの長さは反比例するものと思われる。   According to Japanese Utility Model Publication No. Hei 4-16303, the total length of the slide groove 12a and the indicator portion 12d must be set within the radius of the arc side, and the length of the slide groove 12a and the indicator portion 12d is inversely proportional. I think that the.

本発明は、上記問題を解決し、より多角的な角度測定の開発を目的としたものである。     The present invention is intended to solve the above problems and to develop a more versatile angle measurement.

この改善策として、任意の長さに切断された２つの直線辺を有する帯状の板で、直尺目盛り側の直線辺の反対側に位置する、直線辺の全てを角度測定部として設定することにより、スライド孔の長さと角度測定部の長さの制限を解除した。     As an improvement measure, a strip-shaped plate having two straight sides cut to an arbitrary length, and setting all of the straight sides located on the opposite side of the straight side on the straight scale side as angle measuring units. Thus, the restriction on the length of the slide hole and the length of the angle measuring part was released.

上述したとおり、角度測定および角度の深さ等の測定に対し、流動的な加工場面の測定の可能性を現実化することが出来た。     As described above, it was possible to realize the possibility of measuring fluid working scenes for angle measurement and angle depth measurement.

分度器の角度目盛りの始点である０゜は、角度測定ブレ−ドの測定部と目盛りブレ−ドの直線辺とを平行に設定したライン上に表示する。     The starting point of the angle scale of the protractor, 0 °, is displayed on a line in which the measurement part of the angle measurement blade and the straight side of the scale blade are set in parallel.
