In addition, there is an angle ruler that can be folded 180 degrees and becomes a straight ruler when fully opened, but there is a drawback that it is difficult to draw an angle line because it is unstable. There is also an angle ruler equipped with a rotary head that can be attached to and detached from a parallel ruler, but there is a drawback that it cannot be used as a ruler alone.

１８０度の広い範囲の任意の角度線が容易に引け、かつ分度器や三角定規の機能を持ち、また、直尺定規としても使え、平行定規やＴ定規と協働すれば簡易製図機として機能し、直尺定規並みの携帯性があり、透明な樹脂による一体成形加工品として製作が可能で、底面に段差がなく製図用として使える事。   It can easily draw any angle line in a wide range of 180 degrees, has a function of protractor and triangle ruler, can also be used as a straight ruler, and functions as a simple drafting machine when cooperating with a parallel ruler or T ruler. It is portable like a straight ruler, can be manufactured as an integrally molded product with a transparent resin, and can be used for drafting without any step on the bottom.

直尺定規本体中央部に、角度目盛りを付した角度定規を１８０度回転可能で任意の角度線を容易に引ける回転ヘッドを具備し、また直尺定規本体には片方縁に目盛りを付して直尺定規としての機能を持たせ、その下部左右には角度定規収納スペースを設けて、角度定規を直尺定規本体に収納出来る形状にした。   At the center of the straight ruler body, it is equipped with a rotary head that can rotate an angle ruler with an angle scale 180 degrees and easily draw any angle line, and the straight ruler body has a scale on one edge. It has a function as a straight ruler, and an angle ruler storage space is provided on the left and right sides of the lower part so that the angle ruler can be stored in the straight ruler body.

請求項１記載の発明によれば、１８０度の広い範囲の任意の角度線が容易の引ける角度定規（５）を軸支した直尺定規本体（１）により、三角定規や分度器の機能を持ち、平行定規やＴ定規と協働すれば簡易製図機として機能し、また、直尺定規単体としても使える。

定規部（１３）と分度器部（６）には図５と図６に示すように分度器部（６）の底面（１２）と定規部（１３）の底面（１３ｃ）との間に段差（２５）を形成している。その段差（２５）の側面は底面（１２）と（１３ｃ）と垂直であり、方向は定規部（１３）の長手方向と直角にしてある。この段差（２５）の高さは図３に示す直尺定規本体（１）の底面（２４）から図２に示す円弧状にせり出した凸部（４ｂ）の座面（４ａ）までの高さと等しくしてあり、直尺定規本体（１）に角度定規（５）を軸支した状態において角度定規（５）の底面（１３ｃ）と直尺定規本体（１）の底面（２４）との段差が無い形状にしてある。また、この段差（２５）の位置は、分度器部（６）の中心からの距離が直尺定規本体（１）の凸部（４ｂ）の半径の長さより若干長くしてある。これは角度定規（５）が直尺定規本体（１）の軸（８）に軸支された状態において１８０度回転しても接触しないようにしてある。   As shown in FIGS. 5 and 6, the ruler portion (13) and the protractor portion (6) have a step (25) between the bottom surface (12) of the protractor portion (6) and the bottom surface (13c) of the ruler portion (13). ) Is formed. The side surface of the step (25) is perpendicular to the bottom surfaces (12) and (13c), and the direction is perpendicular to the longitudinal direction of the ruler portion (13). The height of the step (25) is the same as the height from the bottom surface (24) of the straight ruler main body (1) shown in FIG. 3 to the seating surface (4a) of the convex portion (4b) protruding in an arc shape shown in FIG. The level difference between the bottom surface (13c) of the angle ruler (5) and the bottom surface (24) of the straight ruler body (1) when the angle ruler (5) is pivotally supported on the straight ruler body (1). There is no shape. Further, the position of the step (25) is set such that the distance from the center of the protractor portion (6) is slightly longer than the length of the radius of the convex portion (4b) of the straight ruler body (1). This is so that even if the angle ruler (5) rotates 180 degrees in a state where it is supported by the shaft (8) of the straight ruler body (1), it does not come into contact.

定規部（１３）と分度器部（６）には図５と図６に示すように定規部（１３）の上面（１３ｄ）と分度器部（６）の上面（６ｃ）との間に円弧状の段差（２６）を半円弧状の円弧部（６ａ）の稜線上に形成している。この段差（２６）の円弧部（６ａ）の半径の大きさは直尺定規本体（１）の凹部（３）の半径の大きさより僅かに小さくしてある。また、直尺定規本体（１）に角度定規（５）が軸支された状態において、直尺定規本体（１）の上面（図示せず）の底面（２４）からの高さは、角度定規（５）の定規部（６）の上面（６ｃ）の高さより僅かに高くしてある。これは図９と図１１の断面詳細図と組立図１４から分かるように、直尺定規本体（１）に補強プレート（１４）を後述のように取り付けた状態において、分度器部（６）の上面（６ｃ）と補強プレート（１４）の底面（図示せず）との間に僅かの隙間を設けるためであり、この隙間に起因して角度定規（５）が円滑に回転出来るようにしてある。   As shown in FIGS. 5 and 6, the ruler part (13) and the protractor part (6) have an arc shape between the upper surface (13d) of the ruler part (13) and the upper surface (6c) of the protractor part (6). The step (26) is formed on the ridge line of the semicircular arc portion (6a). The radius of the arc portion (6a) of the step (26) is slightly smaller than the radius of the recess (3) of the straight ruler body (1). In addition, in a state where the angle ruler (5) is pivotally supported on the straight ruler main body (1), the height from the bottom surface (24) of the upper surface (not shown) of the straight ruler main body (1) is the angle ruler. It is slightly higher than the height of the upper surface (6c) of the ruler portion (6) of (5). As can be seen from the cross-sectional detail views of FIGS. 9 and 11 and the assembly drawing 14, the upper surface of the protractor portion (6) in a state where the reinforcing plate (14) is attached to the straight ruler main body (1) as described later. This is because a slight gap is provided between (6c) and the bottom surface (not shown) of the reinforcing plate (14), and the angle ruler (5) can be smoothly rotated due to this gap.

次に補強プレート（１４）について詳述する。図１と図９と、図２の２点鎖線で直尺定規本体（１）に取り付け状態の外周の稜線を想像線で示すように、両端に座繰り孔（１８ａ）と（１８ｂ）を有し、皿ビス（１７ａ）と（１７ｂ）を直尺定規本体（１）に設けた座繰り加工を施した孔（１５ａ）と（１５ｂ）を貫通し、その孔（１５ａ）と（１５ｂ）の座繰り部（図示せず）に圧挿して固定されたナット（１６ａ）と（１６ｂ）の螺子部に螺合させて取り付けてある。この補強プレート（１４）の長手方向の側面には円弧部（１４ａ）と（１４ｂ）を形成する。その円弧部（１４ａ）と（１４ｂ）の中心は、取り付けられた状態において直尺定規本体（１）の軸（８）の中心と同じにしてある。円弧部（１４ａ）の円弧の大きさは図１と図１２と図１３に示す連結手段の摘み付ボルト（１９）の座面（２０）を有する外形の円弧よりその半径を僅かに大きくしてある。また、円弧部（１４ｂ）の円弧の半径の大きさも直尺定規本体（１）の凹部（３）の円弧の半径より若干大きくしてある。これは、直尺定規本体（１）の凹部（３）の円弧と角度定規（５）の円弧部（６ａ）により形成される僅かな隙間を覆う形状と成し、蓋の役目を果している。   Next, the reinforcing plate (14) will be described in detail. As shown in FIG. 1 and FIG. 9 and the ridge line of the outer periphery attached to the straight ruler main body (1) by the two-dot chain line in FIG. 2, there are countersink holes (18a) and (18b) at both ends. Then, countersunk holes (15a) and (15b) provided in the straight ruler body (1) with countersunk screws (17a) and (17b) are passed through the holes (15a) and (15b). The nuts (16a) and (16b) that are fixed by being press-fitted into a countersunk portion (not shown) are screwed onto the screw portions. Arc portions (14a) and (14b) are formed on the side surface in the longitudinal direction of the reinforcing plate (14). The centers of the arc portions (14a) and (14b) are the same as the center of the axis (8) of the straight ruler main body (1) in the attached state. The arc of the arc portion (14a) is slightly larger in radius than the arc of the outer shape having the seating surface (20) of the knob bolt (19) of the connecting means shown in FIGS. 1, 12, and 13. is there. The radius of the arc of the arc portion (14b) is also slightly larger than the radius of the arc of the recess (3) of the straight ruler body (1). This has a shape that covers a slight gap formed by the arc of the concave portion (3) of the straight ruler main body (1) and the arc portion (6a) of the angle ruler (5), and serves as a lid.

この補強プレート（１４）は、前記の位置に取り付ける事により固定ばりとしての役目を果す。前記より直尺定規本体（１）の中央部の半円弧状の凹部（３）や軸（８）に、取扱時の操作に起因して発生する外力による応力集中の緩和が図れ、かつ直尺定規本体（１）自身の剛性の向上を図る事が出来る。また、角度定規（５）の分度器部（６）を、補強プレート（１４）の底面（図示せず）と直尺定規本体（１）の座面（１４ａ）で挟んだ形状と成す事により、角度定規（５）の回転方向に対して直角方向の振れを無くすと共に角度定規（５）の剛性の向上を図る事が出来る。   The reinforcing plate (14) serves as a fixed beam by being attached at the above position. As described above, stress concentration due to external force generated due to an operation during handling can be reduced in the semicircular arc-shaped concave portion (3) and shaft (8) in the central portion of the straight ruler body (1), and the straight ruler The rigidity of the ruler body (1) itself can be improved. Further, by forming the protractor portion (6) of the angle ruler (5) between the bottom surface (not shown) of the reinforcing plate (14) and the seat surface (14a) of the straight ruler main body (1), It is possible to eliminate runout in the direction perpendicular to the rotation direction of the angle ruler (5) and to improve the rigidity of the angle ruler (5).

次に、図１と図１２と図１３と図１１の断面詳細図に示す連結手段の摘み付ボルト（１９）について詳述する。摘み付ボルト（１９）は、摘み部（２７）と螺子部（２８）をから成り、螺子部（２８）は金属で造られておりその端部に頭部（図示せず）を有しており、摘み部（２７）は樹脂製の成型品として造られている。その摘み部（２７）に螺子部（２８）の頭部（図示せず）を埋め込んだ状態において成形加工された一体成型品として造られている。摘み部（２７）の下部外周部に環状突起面（２０）を形成している。   Next, the knob bolt (19) of the connecting means shown in the cross-sectional detail views of FIGS. 1, 12, 13, and 11 will be described in detail. The bolt with knob (19) includes a knob portion (27) and a screw portion (28). The screw portion (28) is made of metal and has a head (not shown) at its end. The knob (27) is made as a resin molded product. It is manufactured as an integrally molded product that is molded in a state where the head portion (not shown) of the screw portion (28) is embedded in the knob portion (27). An annular projecting surface (20) is formed on the lower outer peripheral portion of the knob (27).

この連結手段の摘み付ボルト（１９）は、角度定規（５）が直尺定規本体（１）に軸支され、かつ、補強プレート（１４）を前記の方法で直尺定規本体（１）に取付けた状態において、前記のように直尺定規本体（１）に固定された鍔付ナット（１０）の螺子部（図示せず）とこの摘み付ボルト（１９）の螺子部（２８）とを螺合させて組立られている。この連結手段の摘み付ボルト（１９）の摘み部（２７）の回転方向により前記の発明を実施するための形態で述べたように角度定規（５）を直尺定規本体（１）に、任意の角度に固定したり緩めたりする事ができる。   The bolt with a knob (19) of the connecting means has an angle ruler (5) pivotally supported on the straight ruler main body (1), and the reinforcing plate (14) is attached to the straight ruler main body (1) by the above method. In the mounted state, the screw portion (not shown) of the hooked nut (10) fixed to the straight ruler main body (1) as described above and the screw portion (28) of the knob bolt (19) are connected. It is assembled by screwing. As described in the embodiment for carrying out the invention according to the rotation direction of the knob portion (27) of the bolt (19) with the knob of the connecting means, the angle ruler (5) is arbitrarily attached to the straight ruler body (1). The angle can be fixed or loosened.

次に、本発明を組立た状態において詳述する。図１４と図１６は、それぞれ角度定規（５）を左右に全傾して、連結手段の摘み付ボルト（１９）により直尺定規本体（１）に固定された状態を示す。この状態において、図５の定規部（１３）の目盛を付した面（１３ａ）と（１３ｂ）が直尺定規本体（１）の側面縁（２ｂ）より外側にはみ出している。これは、（１３ａ）と（１３ｂ）の目盛を直尺定規本体（１）の直尺目盛として機能させて利便性を図る為である。   Next, the present invention will be described in detail in an assembled state. FIG. 14 and FIG. 16 show a state in which the angle ruler (5) is tilted to the left and right and is fixed to the straight ruler main body (1) by the bolt with a knob (19) of the connecting means. In this state, the scaled surfaces (13a) and (13b) of the ruler portion (13) in FIG. 5 protrude beyond the side edge (2b) of the straight ruler body (1). This is to make the scales (13a) and (13b) function as a straight scale of the straight ruler body (1) for convenience.

図１５は、角度定規を右上りの３０度に固定した状態を示す。この状態では図２の直尺定規本体（１）の基線（２１ｄ）と角度定規（５）の円弧部（６ａ）に付してある角度目盛の３０度の位置とを一致させて、連結手段の摘み付ボルト（１９）で固定している。直角定規として機能させる時は、上記のように操作して角度目盛を９０度に合わせる。以上のように、本発明により、任意の角度に角度定規（５）を容易に固定出来るとともに、固定された角度が直視出来るので誤操作の心配がない。   FIG. 15 shows a state in which the angle ruler is fixed at 30 degrees on the upper right. In this state, the base line (21d) of the straight ruler main body (1) of FIG. 2 and the position of the angle scale attached to the circular arc part (6a) of the angle ruler (5) are made to coincide with each other by 30 degrees. The bolt with the knob (19) is fixed. When functioning as a right angle ruler, the angle scale is adjusted to 90 degrees by operating as described above. As described above, according to the present invention, the angle ruler (5) can be easily fixed at an arbitrary angle, and since the fixed angle can be directly viewed, there is no fear of erroneous operation.

本発明により、安価な平行定規やＴ定規と協働して角度線が引けることにより簡易製図機とし使用できる。また、方眼紙や水平の段落線を有した紙面を使用すれば平行定規やＴ定規を使用しなくても、紙面の水平線と直尺本体の目盛を付した面または両側に付した基線を水平に一致した状態で、所望の角度に角度定規を固定して角度線を容易に引くことができる。また、多数の等間隔の線を引く場合は、基準点を段落線上に設定して、線の間隔の寸法分だけ直尺定規本体に付した目盛を利用して移動させれば容易に引くことができる。また、角度定規は収納した状態で使えば、角度定規の目盛を付した線縁面や目盛も直尺定規として機能する。端点や交点などを結ぶ斜線を引くときは、直尺定規本体はほぼ水平の状態のままで、角度定規だけを回転させて引くと容易かつ迅速に引くことができる。   The present invention can be used as a simple drafting machine by drawing an angle line in cooperation with an inexpensive parallel ruler or T ruler. In addition, if you use graph paper or paper with horizontal paragraph lines, the horizontal line on the paper and the base line on both sides of the scale body or the base line on both sides can be leveled without using a parallel ruler or T ruler. The angle ruler can be fixed at a desired angle and the angle line can be easily drawn. Also, when drawing a large number of equally spaced lines, set the reference point on the paragraph line and move it easily by using the scale attached to the straight ruler body by the distance between the lines. Can do. If the angle ruler is used in the retracted state, the line edge surface and the scale with the angle ruler scale function also as a straight ruler. When drawing diagonal lines connecting end points, intersections, etc., the straight ruler main body remains in a substantially horizontal state and can be drawn easily and quickly by rotating only the angle ruler.

上記記載の内容から、安価な平行定規やＴ定規と協働して使用することにより簡易設計・製図器として使用できる。また工業系の学生にも利用される事により、場所を製図室に限らず設計・製図や作図ができる。また、ペンケースに収納可能な小型のサイズを造れば、学童でも使用出来る。   From the above description, it can be used as a simple design / drawer by using it in cooperation with an inexpensive parallel ruler or T ruler. It can also be used by industrial students to design, draft, and draw not only in the drawing room. Also, if you make a small size that can be stored in a pen case, it can be used by school children.
