[Prior art]

図１は、ゴムシートを円形に切抜いてゴムパッキンを作るために従来用いられている治具を示すもので、センターピン１と、先端に刃２を設けたピン３と、両ピン１及び３に通されるロッド４と、両ピンの間隔を調節したのち、ロッド４を止着するボルト５よりなり、センターピン上のボルト５を押さえてセンターピン１をゴムシート上に押し付けた状態で、刃２がゴムシート６に喰込むようにピン３を押込んでセンターピン１の回りに少しづつ回転させては、刃２でゴムシート６に切込みを入れてゴムパッキンを得ている。 FIG. 1 shows a jig that has been conventionally used to cut a rubber sheet into a circle to make a rubber packing. The center pin 1, a pin 3 having a blade 2 at its tip, and both pins 1 and 3 are shown. After adjusting the distance between the rod 4 and the pin that is passed through the rod 4, the bolt 5 that fixes the rod 4 is fixed. While pressing the bolt 5 on the center pin and pressing the center pin 1 on the rubber sheet, The pin 3 is pushed in so that the blade 2 bites into the rubber sheet 6 and rotated little by little around the center pin 1, and then the rubber sheet 6 is cut by the blade 2 to obtain the rubber packing.

[Problems to be solved by the device]

上述する従来の治具では、ピンをセンターピンの回りに押込むようにして回転させる際には、センターピン側のボルトも同時に回動操作せねばならず、硬質プレートに刃が食込むようにして押込み、切込みを入れる際にはことに芯ずれを生じ易く、芯ずれを生じないように切込み操作を行うにはかなりな熟練を要する。 In the above-mentioned conventional jig, when the pin is pushed around the center pin and rotated, the bolt on the center pin side must also be rotated at the same time. When inserting, it is easy to cause misalignment, and a considerable skill is required to perform the cutting operation so as not to cause misalignment.

【０００４】上述する治具はまた、刃を白墨や筆記用具に取換えて円を描くのにも用いることができるが、この場合にも上記と同様の問題を生ずる。本考案は、上述する治具に改良を加え、円形に切込みを入れたり、円を描くのが従来のものよりも容易に行えるようにしたものである。The jig described above can also be used to draw a circle by replacing the blade with a black ink or a writing instrument, but this also causes the same problem as above. The present invention is an improvement of the above-mentioned jig so that a circular cut or circle can be made more easily than the conventional one.

[Means for solving the problem and action]

本考案の治具はそのため、センターピンと、先端に刃或いは筆記用具を取付けたピンと、両ピンに通されるロッドと、ピンに捩込まれ、ロッドを止着するボルトよりなる治具において、センターピンに捩込まれるボルト上につまみを回転自在に軸着して設けたことを特徴とするものである。 Therefore, the jig of the present invention is a jig having a center pin, a pin having a blade or a writing implement attached to the tip, a rod that is passed through both pins, and a bolt that is screwed into the pin and fastens the rod. It is characterized in that a knob is provided on a bolt screwed into the center pin so as to be pivotally attached to the center pin in a rotating manner.

【０００６】本考案の治具によれば、つまみを押えておいてピンをセンターピンの回りに回転させると、ピンの回転に伴いセンターピンがつまみに対して回転し、つまみは回転しない。別の考案の治具では、センターピンがロッドの通される本体と、該本体の下端に回転自在に連結される先端部とより構成され、本体に捩込まれるボルト上につまみが回転自在に軸着される。According to the jig of the present invention, when the knob is pressed and rotated about the center pin, the center pin rotates with respect to the knob as the pin rotates, and the knob does not rotate. In a jig of another invention, a center pin is composed of a main body through which a rod passes, and a tip part rotatably connected to a lower end of the main body, and a knob is rotatable on a bolt screwed into the main body. Is pivoted on.

【０００７】本考案の治具によれば、ピンをセンターピンの回りに回転させると、本体のみが回転し、つまみと先端部は回転しない。ピンの回転時、つまみと先端部は静止するため芯がずれにくい。According to the jig of the present invention, when the pin is rotated around the center pin, only the main body is rotated, and the knob and the tip are not rotated. When the pin is rotated, the knob and tip end are stationary, so the core does not easily slip.

【Example】

図２に示す治具は、センターピン１１に捩込まれ、ロッド１２を止着するボルト１３上に突設される軸部１０につまみ１４をベアリング１５を介して回転自在に軸着したものである。図３に示す治具は、図２に示す治具において、センターピン１１をロッド１２が通される本体１６と、本体下端に突設される軸部１７に回転自在に嵌合する先端部１８と、先端部１８に捩込まれ、先端が軸部１７の円周溝１９に係合するネジ２０とで構成したものである。 The jig shown in FIG. 2 is one in which a knob 14 is rotatably attached via a bearing 15 to a shaft portion 10 which is screwed into a center pin 11 and is projected on a bolt 13 for fixing a rod 12. Is. The jig shown in FIG. 3 is the same as that shown in FIG. 18 and a screw 20 which is screwed into the tip portion 18 and whose tip engages with the circumferential groove 19 of the shaft portion 17.

[Effect of device]

本考案は以上のように構成され、次のような効果を奏する。請求項１記載の治具によれば、円形に切込みを入れたり、円を描くため、ピンをセンターピンの回りに回す際には、つまみを押えておくだけで、回動操作する必要がないから操作が容易となり、ことに円切りや溝を付ける場合のように、ピンに力を入れて操作する場合には、つまみを回さなくてもよいために芯ずれが生じにくい。 The present invention is configured as described above and has the following effects. According to the jig described in claim 1, since a circular cut is made or a circle is drawn, when the pin is rotated around the center pin, it is only necessary to hold the knob, and it is not necessary to rotate it. It is easy to operate, and when you operate by putting a force on the pin, especially when you make a circle or a groove, misalignment is less likely to occur because you do not have to turn the knob.

【００１０】請求項２記載の治具においては更に、ピンの回動操作中、センター部は静止するため、芯ずれがより生じにくゝ、円形にきれいに切取り、或いは円を描くことができる。Further, in the jig according to the second aspect, since the center portion is stationary during the pivoting operation of the pin, misalignment is less likely to occur, and it is possible to cut the circle neatly or draw a circle. .
