Description

[Detailed description of the device]

【０００１】[0001]

[Industrial applications]

本考案は、角度のある線を描くのに適した作図器に関する。 The present invention relates to a plotter suitable for drawing an angled line.

【０００２】[0002]

[Prior art]

この種の代表的な作図器が英国特許第７３８、２３２号に開示されている。この作図器は、一端に形成され、ベースに回転可能に支持される円形部分を有するアームからなっている。 A representative plotter of this type is disclosed in British Patent 738,232. The plotter consists of an arm with a circular portion formed at one end and rotatably supported by the base.

【０００３】[0003]

[Problems to be solved by the device]

上述する従来の作図器は、アームがことに作図中にベースから外れがちで、使用者に不具合を感じさせていた。しかもアームとトップエッジで角の両側に線を描くとき、角の両側の連結部分が円形部分によって邪魔をされるため、作図器を取去らないと、角を完成することができず、これまた不便であった。 In the conventional plotter described above, the arm tends to come off from the base during the drawing, which causes the user to feel a problem. Moreover, when drawing lines on both sides of the corner with the arm and top edge, the connecting parts on both sides of the corner are obstructed by the circular part, so the corner cannot be completed unless the plotter is removed. It was inconvenient.

【０００４】本考案は、角度のある線を容易かつ迅速に描くことのできる作図器を提供することを目的とする。An object of the present invention is to provide a plotter capable of easily and quickly drawing an angled line.

【０００５】[0005]

[Means for solving the problem]

本考案の作図器は、一端に第一の頭部を有する第一の定規と、一端に第二の頭部を有する第二の定規とからなり、第一の頭部に円形ないし環状の凸部を設ける一方、第二の頭部に円形ないし環状溝を形成して上記凸部をスライド可能に嵌合させ、第一の定規と第二の定規を互いに回転できるようにしたことを特徴とするものである。 The plotter of the present invention comprises a first ruler having a first head at one end and a second ruler having a second head at one end. On the other hand, a circular or annular groove is formed on the second head to slidably fit the convex portion so that the first ruler and the second ruler can rotate relative to each other. It is something to do.

【０００６】本考案の作図器において、第一及び第二の定規には、好ましくは頭部にそれぞれ小さな透孔が形成される。透孔を通して表面に描かれる中心点と一致させることにより、頭部の中心を表面の中心点と一致させるのが容易にできるようになる。両定規の頭部にはまた、一方の頭部にピン要素を設けて他方の頭部に形成される円弧溝にスライド可能に嵌合させ、円弧溝の範囲内で両定規が互いに回動できるようにするのが望ましく、ピン要素はボルトとナットを含み、両定規が互いに離脱しないように連結されるのが望ましい。In the plotter of the present invention, each of the first and second rulers is preferably formed with a small through hole in the head. By making it coincide with the center point drawn on the surface through the through hole, it becomes easy to match the center of the head with the center point of the surface. The heads of both rulers also have a pin element on one head that is slidably fitted into the arc groove formed on the other head so that both rulers can rotate relative to each other within the range of the arc groove. Preferably, the pin element includes a bolt and a nut, and the rulers are connected so as not to come off from each other.

【０００７】第一の定規の第一の頭部にはまた、角度の目盛を形成する一方、第二の定規の第二の頭部には、上記目盛を拡大するための凸レンズを設け、目盛の読取りが容易に行えるようにすると共に、目盛りを指示するポインターを設け、角度の読取りが容易に行えるようにするのが望ましい。The first head of the first ruler is also formed with an angular scale, while the second head of the second ruler is provided with a convex lens for enlarging the scale, It is desirable that the reading of the angle be easy and that a pointer that points the scale be provided so that the angle can be easily read.

【０００８】[0008]

【Example】

図１ないし図３に示されるように、作図器は二つの定規１０、２０を有し、各定規は一端に形成される頭部１１、２１を有し、角頭部は３／４円形をなしている。そして一方の頭部１１は環状の凸部１２を備えていると共に、他方の頭部２１は上記突出部１２が嵌合する環状溝２２を有し、環状の凸部１２と環状溝２２とのスライドによって定規１０、２０が互いに回転できるようになっている。 As shown in FIGS. 1 to 3, the plotter has two rulers 10 and 20, each ruler has a head 11 and 21 formed at one end, and a square head has a 3/4 circular shape. I am doing it. One of the heads 11 is provided with an annular protrusion 12, and the other head 21 is provided with an annular groove 22 into which the protrusion 12 fits. The slides allow the rulers 10 and 20 to rotate relative to each other.

【０００９】各頭部はまた、それぞれ中心部に形成さる孔１４、２４を有し、図３に示されるように、使用者が頭部１１、２１の中心を透視し、また頭部の中心を表面に描かれる中心点と一致させることができるようになっている。ピン要素、例えば図に示されるように、ボルト１５が第一定規１０の頭部に係合し、このボルト１５が第二定規２０の頭部２１に形成される円弧溝２５に係合することによって二つの定規１０、２０が互いに分離することなく連結されると共に、図４に示されるように一定範囲内で動かすことができるようになっている。Each head also has holes 14 and 24 formed in the center thereof, respectively, so that the user can see through the centers of the heads 11 and 21 as shown in FIG. The center can be made to coincide with the center point drawn on the surface. A pin element, for example, a bolt 15 engages with the head of the first ruler 10 as shown in the figure, and this bolt 15 engages with a circular arc groove 25 formed in the head 21 of the second ruler 20. Thus, the two rulers 10 and 20 are connected to each other without being separated from each other, and can be moved within a certain range as shown in FIG.

【００１０】第一の定規１０の頭部１１には、角度の目盛１６が形成されると共に、第二の定規２０の頭部２１には、凸レンズ２６が設けられ、上記目盛１６を拡大して見ることができるようにしてある。第二の定規２０の頭部２１には更に、定規１０、２０の二つの頭部１１、２１の間の相対的な回転位置に相当する角度の値を指示するポインター２８が形成されている。An angle scale 16 is formed on the head 11 of the first ruler 10, and a convex lens 26 is provided on the head 21 of the second ruler 20 to enlarge the scale 16. I can see it. The head 21 of the second ruler 20 is further formed with a pointer 28 for indicating the value of the angle corresponding to the relative rotational position between the two heads 11, 21 of the rulers 10, 20. .

【００１１】使用に際しては、図５に示されるように、第一の定規を線を描く表面の上に置き、第二の定規を第一の定規に対して回転、例えば図５に示されるようにポインター２８が３０°を指すように、第一の定規を第一の定規１０に対して３０°回転させる。これにより３０°の角度が容易に描かれる。同様にして１８０°までの角が容易に描かれ、角を描くために作図器を取去る必要がない。In use, as shown in FIG. 5, a first ruler is placed on the surface to be drawn and a second ruler is rotated with respect to the first ruler, for example as shown in FIG. Thus, the first ruler is rotated by 30 ° with respect to the first ruler 10 so that the pointer 28 points at 30 °. This makes it easy to draw an angle of 30 °. Similarly, corners up to 180 ° are easily drawn and there is no need to remove the plotter to draw the corners.
