本考案の請求項１の防振ゴムは、平板状のゴム体の外縁部の複数箇所に、端部 近傍にナットが埋入され、かつ中間部に圧縮量を規制する長さに設定されたスト ッパ筒が嵌入された円筒ゴム体をそれぞれ配置して一体成型し、前記円筒ゴム体 に締付けボルトを嵌入し前記ナットに螺合したことを特徴とする。 The anti-vibration rubber according to claim 1 of the present invention is such that nuts are embedded in a plurality of locations on the outer edge of a flat rubber body near the ends, and the length is set to regulate the amount of compression in the middle. It is characterized in that cylindrical rubber bodies in which the stopper cylinders are fitted are respectively arranged and integrally molded, and a tightening bolt is fitted into the cylindrical rubber body and screwed into the nut.
【０００５】 また、本考案の請求項２の防振ゴムは、ゴム体の、円筒ゴム体が突出する面と 反対の面に保持された機器基板を包囲するように成型された縁部ゴムが、前記ゴ ム体と一体を成すように設けられ、請求項１に記載されたことを特徴とする。Further, in the vibration-proof rubber according to claim 2 of the present invention, an edge rubber molded so as to surround the equipment substrate held on the surface of the rubber body opposite to the surface from which the cylindrical rubber body projects It is provided so as to be integrated with the rubber body, and is described in claim 1.
【０００６】[0006]
本考案の防振ゴムにより筐体の支持板と機器基板とを締結すれば、部品点数が 減少して組立工程が短縮され、さらにストッパ筒とナットが当接するまで締付け ボルトをねじ込むことにより円筒ゴム体を予め規制された圧縮量にすることがで きるため、トルク管理が不要になる。 If the support plate of the housing and the device board are fastened with the anti-vibration rubber of the present invention, the number of parts will be reduced and the assembly process will be shortened. Since the body can be compressed in advance, the torque management becomes unnecessary.
【０００７】[0007]
以下に本考案の防振ゴムの一実施例を示す。 図１に示す通り、ドーナツ型を有する平板状のゴム体１０の外縁部に突出する ように、４個の円筒ゴム体１１がゴム体１０と一体成型されている。円筒ゴム体 １１の中央には、ゴム体１０も挿通する貫通孔１２が設けられており、また円筒 ゴム体１１の端部近傍にはナット１３が埋入されている。さらに、金属あるいは 硬質樹脂等からなり、予め円筒ゴム体１１の圧縮量を規制する長さに設定された ストッパ筒１４が、円筒ゴム体１１の貫通孔１２内に嵌入されている。ゴム体１ ０および円筒ゴム体１１は、耐オゾン性、耐候性に優れた合成ゴムにより形成さ れている。 上記した本考案の防振ゴムを使用する場合は、機器１５を締結しようとする筐 体の支持板１６の取付孔１７に本考案の防振ゴム１８の円筒ゴム体１１を挿通し 、防振ゴム１８の上に機器１５を搭載する。そして、貫通孔１２と重なるように 機器基板１９上に設けられたボルト孔２０を合わせ、貫通孔１２に座金２１を介 して締付けボルト２２をねじ込む。締付けボルト２２をナット１３に螺合するに つれて、図３に示す通り支持板１６の下面を押圧するように円筒ゴム体１１が変 形膨脹して、機器１５を保持する。締付けボルト２２は、ストッパ筒１４の両端 がナット１３と機器基板１９に当接するまで螺合すれば良い。 An embodiment of the anti-vibration rubber of the present invention will be shown below.
