【選択図】図１An object of the present invention is to develop and provide a straight-line ruler for a blackboard that makes it easy to draw a line without disturbing the handle.
A straight ruler main body (1) is characterized in that a handle (2) is provided at one end in the longitudinal direction, and scales (3) (3 ') are provided on both sides and both sides in the longitudinal direction. The ruler body (1) is made of a semi-transparent synthetic resin, but is not limited to this material, and other members may be used. In addition, any color may be used, and furthermore, a magnet sheet (4) may be provided on each end of the back surface of the ruler body (1). When used on a board, the ruler body (1) is magnetically attracted to the ruler body (1) and can be firmly fixed.

Description
この考案は、学校、学習塾等の教壇上で教師が黒板に向かって使用する、黒板用直線定規に関する。 The present invention relates to a blackboard linear ruler that teachers use toward a blackboard on a school or school cram school.
従来、この黒板用直線定規（以下、この直線定規は、黒板はもとより、ホワイトボード等の筆記板をすべて含むものである。）は、垂直か、あるいはやや傾斜した黒板、あるいはホワイトボードで使用するため、定規を押さえた状態で、定規に添って、白墨やサインペンで直線を倣って描くものである。 Conventionally, this straight line ruler for blackboard (hereinafter, this straight line ruler includes not only blackboards but also all whiteboards and other writing boards) is used for vertical or slightly inclined blackboards or whiteboards. With the ruler held down, a straight line is drawn along with the ruler with white ink or a pen.
しかしながら、比較的長めの定規では、定規をしっかりと押さえておかないと、定規の先端の方では、筆記具の力によって定規が動いてしまうという欠点があった。 However, a relatively long ruler has a drawback in that the ruler moves by the force of the writing instrument at the tip of the ruler unless the ruler is firmly held down.
そのため、定規の長手方向に大きなアーチ状の把手を設け、しっかりと固定できるものが存在するが、その結果、先端部での振れはなくなるものの、把手部分が定規の全体にあるため、把手に握った手が邪魔となり、線が描きにくいものであった。例えば、特許文献１のように。
そこでこの考案は、把手が邪魔にならず、線を描きやすい黒板用直線定規を開発・提供することにある。 Therefore, the present invention is to develop and provide a straight line ruler for a blackboard that makes it easy to draw a line without disturbing the handle.
そこでこの考案は、直線定規本体（１）において、中央部を避けて、長手方向の一端部に、把手（２）を設けると共に、長手方向の側面、両側にそれぞれ目盛り（３）（３′）を設けた黒板用直線定規である。 Therefore, in the straight ruler main body (1), the present invention is provided with a handle (2) at one end in the longitudinal direction, avoiding the central portion, and scales (3) and (3 ') on the side and both sides in the longitudinal direction. This is a blackboard straight ruler.
この考案によると、直線定規本体（１）において、長手方向の一端部に、把手（２）を設けることにより、中央部を避けることにより、該直線定規を使用して線が描きやすく、また、目盛り（３）は、直線定規本体（１）の両側にそれぞれ設けてあるため、右利きの場合は、図１に示すように、左手で把手（２）を握り、右手で白墨やサインペンを持ち、定規本体（１）の目盛り（３）に添って倣って線を描けばよく、左利きの場合には、直線定規本体（１）を逆さにして持ち、把手（２）を、直線定規本体（１）の右側に位置させ、同様に定規本体の目盛り（３′）に添って倣って線を描けばよい等極めて有益なる効果も有するものである。 According to this device, in the straight ruler main body (1), it is easy to draw a line using the straight ruler by providing a handle (2) at one end in the longitudinal direction, thereby avoiding the central portion, The scale (3) is provided on both sides of the straight ruler body (1). If you are right-handed, grab the handle (2) with your left hand and hold the black ink or pen with your right hand as shown in Figure 1. If you are left-handed, hold the straight ruler body (1) upside down and hold the handle (2) with the straight ruler body ( It is also located on the right side of 1), and also has a very beneficial effect such as drawing a line along the scale (3 ') of the ruler body.
以下、この考案の一実施例を図１及び図２に基づいて詳細に説明すると、直線定規本体（１）において、長手方向の一端部に、把手（２）を設けると共に、長手方向の側面、両側にそれぞれ目盛り（３）（３′）を設けたことを特徴とする黒板用直線定規から構成されるものである。 Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 and FIG. 2. In the linear ruler main body (1), a handle (2) is provided at one end in the longitudinal direction, a side surface in the longitudinal direction, It is composed of a blackboard straight ruler characterized in that scales (3) and (3 ') are provided on both sides.
また、定規本体（１）の素材は、半透明の合成樹脂を使用しているが、この材質に限定されることはなく、他の部材を用いてもよいものであり、また、どのような色に着色したものを用いてもよい。 Further, the material of the ruler body (1) uses a translucent synthetic resin. However, the material is not limited to this material, and other members may be used. You may use what was colored.
さらに、定規本体（１）の裏面の両端部には、それぞれ、マグネットシート（４）設けてもよく、着磁性の黒板、ホワイトボードで使用する際には、定規本体（１）が慈善に吸磁され、定規本体（１）をしっかりと固定できる。 In addition, a magnet sheet (4) may be provided at both ends of the back side of the ruler body (1), and the ruler body (1) absorbs charity when used on a magnetic blackboard or whiteboard. The ruler body (1) can be firmly fixed by being magnetized.
この考案の黒板用直線定規の製造技術を確立することにより、製造・販売を通じて、産業上の利用可能性が大きい。 By establishing the blackboard straight-line ruler manufacturing technology of this device, industrial applicability is great through manufacturing and sales.
