とを特徴とするプロトラクタに係るものである。 A semicircular protractor plate 10 with a scale on the base 10a
In a protractor in which a measuring rod 11 with a scale attached to the center thereof is rotatably provided on a support shaft 12, a fixed rod 13 of a predetermined length with a scale attached to the bottom side 10a of the protractor plate 10 is attached to the bottom side 10a. When the measuring rod 11 is set at a right angle to the bottom side 10a of the protractor plate 10, the side edge of the measuring rod 11 and the fixed rod 13 are fixed. A fixed rod 14 with a scale continuous with the scale marked on the bottom side 10a of the protractor plate 10 is fixedly protruding from the arcuate edge 10b of the protractor plate 10. , the side edge of this fixed rod 14 and the protractor plate 10
This relates to a protractor characterized in that the base side 10a of the protractor is set to be in a straight line.
第３図に示すように測定竿１１を少し回動させ
て測定竿１１を固定すると測定竿１１と固定竿１
３との間で鋭角の測定が出来る。
As shown in FIG. 3, when the measuring rod 11 is fixed by slightly rotating the measuring rod 11, the measuring rod 11 and the fixed rod 1
Acute angles can be measured between 3 and 3.
第４図に示すように測定竿１１を想像縁のよう
に大きく回動すると鈍角の測定が出来る。 As shown in FIG. 4, by rotating the measuring rod 11 by a large amount like an imaginary edge, obtuse angles can be measured.
同じく第４図に示すように測定竿１１を固定竿
１３の上縁にぴつたりと当接させ、若しくは測定
竿１１を固定竿１４上に重合させることにより直
角を測定することが出来る。 Similarly, as shown in FIG. 4, the right angle can be measured by bringing the measuring rod 11 into tight contact with the upper edge of the fixed rod 13, or by overlapping the measuring rod 11 on the fixed rod 14.
また、測定竿１１を外すと、固定竿１３、固定
竿１４とにより直角定規としても使用できる。 Further, when the measuring rod 11 is removed, the fixed rod 13 and the fixed rod 14 can be used as a right angle ruler.
更に、持ち運びに際しては、測定竿１１を回動
されて測定竿１１を固定竿１４に重合させると、
即ち、固定竿１４を測定竿１１の裏側に位置せし
めると、固定竿１４が測定竿１１の保護板の作用
を果たす為、誤つて本案品を落としたりしても測
定竿１１に直接衝撃が加わらず、測定竿１１の回
動にとつて一番重要な測定竿１１と分度板１０と
の枢着部が損傷することはない。固定竿１４が存
しない場合には、測定竿１１を保護するものは分
度板１０になる。本考案は固定竿１４の長さ部だ
け余計に測定竿１１の保護が果たされることにな
る。 Furthermore, when carrying, when the measuring rod 11 is rotated and the measuring rod 11 is superimposed on the fixed rod 14,
That is, when the fixed rod 14 is positioned on the back side of the measuring rod 11, the fixed rod 14 acts as a protective plate for the measuring rod 11, so even if the product is accidentally dropped, no direct impact is applied to the measuring rod 11. First, the pivot point between the measuring rod 11 and the protractor plate 10, which is most important for the rotation of the measuring rod 11, will not be damaged. If the fixed rod 14 is not present, the protractor plate 10 protects the measuring rod 11. In the present invention, the measuring rod 11 is additionally protected by the length of the fixed rod 14.
本実施品はステンレス板、プラスチツク板、銅
板等で作ると良い。
This product is preferably made of stainless steel plate, plastic plate, copper plate, etc.
支軸１２はボルト１５と調節ナツト１６とより
構成し、調節ナツト１６をゆるめて測定竿１１を
回動させる場合を図示している。 The support shaft 12 is composed of a bolt 15 and an adjusting nut 16, and the illustration shows a case in which the measuring rod 11 is rotated by loosening the adjusting nut 16.
図中１７は目盛読み取り切欠部である。 In the figure, 17 is a scale reading notch.
本考案は上述の様に分度板の底辺に固定竿を設
けたから第３図に示すように固定竿と測定竿との
間で１〜10°等の鋭角を測定することが出来、ま
た、第４図に示すように測定竿を90°若しくは
180°で固定することにより固定竿、測定竿で直角
を測定することが出来る。
Since the present invention has a fixed rod at the bottom of the protractor as described above, it is possible to measure acute angles such as 1 to 10 degrees between the fixed rod and the measuring rod as shown in Figure 3. As shown in Figure 4, rotate the measuring rod 90° or
By fixing at 180°, you can measure right angles with a fixed rod or measuring rod.
更に本考案は、測定竿を取り外せば、２つの固
定竿間で直角定規としても使用ができる。この
際、２つの固定竿は分度板に固着されている為、
直角定規の使用に何ら支障を来さない。 Furthermore, the present invention can be used as a square ruler between two fixed rods by removing the measuring rod. At this time, since the two fixed rods are fixed to the protractor plate,
It does not interfere with the use of a square ruler.
即ち、直角定規として使用する場合には該直角
定規に罫引き針を当てて罫引き作業をしたりする
が、直角を構成する部分がガタついたりしては作
業が良好に行えない。この点、本考案は２つの固
定竿が分度板に固着されている為、このような問
題は生じない。 That is, when the ruler is used as a right angle ruler, a liner is applied to the ruler to draw the lines, but the work cannot be performed satisfactorily if the parts forming the right angles become loose. In this regard, this problem does not occur in the present invention because the two fixed rods are fixed to the protractor plate.
更に、本考案は固定竿１４が測定竿の保護作用
も果たす為それだけ耐久性に秀れた製品となる。 Furthermore, in the present invention, the fixed rod 14 also serves to protect the measuring rod, resulting in a product with excellent durability.
従つて、本案品一台で鋭角、鈍角の測定は勿論
の事直角を測定することもでき、且つスコヤとし
ても使用することが出来、極めて便利であると共
に経済的である。 Therefore, this product can not only measure acute angles and obtuse angles, but also right angles, and can also be used as a scorer, making it extremely convenient and economical.
そして、固定竿、測定竿を使用して長さを測定
することも出来る。 The length can also be measured using a fixed rod or a measuring rod.
また、本案品は複雑構造ではないから制作も容
易となり、それだけ量産し、製品も低コストで提
供することが出来る等秀れた実用上の効果を有す
るものである。 In addition, since the proposed product does not have a complicated structure, it is easy to manufacture, and it has excellent practical effects such as being able to be mass-produced and providing the product at a low cost.
