Description

【考案の詳細な説明】 これは輪ゴムを利用して回転させるこまの考案である。[Detailed explanation of the idea] This is a spinning top that uses rubber bands.

図面第１図および第２図に示す実施例について説明する
と、１は合成樹脂板製の発射台で、基部中央に切欠２を
設けて左右の分岐片３，４を形成する。To explain the embodiment shown in FIGS. 1 and 2 of the drawings, reference numeral 1 denotes a launch pad made of a synthetic resin plate, and a notch 2 is provided in the center of the base to form left and right branch pieces 3 and 4.

そして左分岐片３の前方における発射台１の一側に長溝
５を穿って移動片６を形威し、左右の分岐片３，４を指
先きで切欠２側に押すと、第１図の点線に示すように合
成樹脂板の有する弾性により移動片６は外側に向は開ら
く。Then, a long groove 5 is bored in one side of the launch pad 1 in front of the left branch piece 3 to form a moving piece 6, and when the left and right branch pieces 3 and 4 are pushed toward the notch 2 side with fingertips, as shown in FIG. As shown by the dotted line, the elasticity of the synthetic resin plate causes the movable piece 6 to open outward.

７は右分岐片４の内側に形成する小切欠で、これに輪ゴ
ムＡを係合する。7 is a small notch formed inside the right branch piece 4, into which the rubber band A is engaged.

８は合成樹脂により成型したこま体で、外周に相対して
突片９，１０を突設し、一方の突片９は移動片６の前端
裏面に設けた突起１１に係止すると共に他方の突片１０
と右分岐片４の前記小切欠７との間に輪ゴムＡを張設し
、その弾力で突片９と突起１１との係止状態を保持する
と共にこま体８の心棒１２を発射台１の先端中央の凹部
１３内に嵌合する。Reference numeral 8 denotes a top body molded from synthetic resin, with protruding pieces 9 and 10 protruding from the outer periphery, one of the protruding pieces 9 being engaged with a protrusion 11 provided on the back surface of the front end of the movable piece 6, and the other protruding piece 9 Projection piece 10
A rubber band A is stretched between the small notch 7 of the right branch piece 4, and its elasticity maintains the locked state between the protrusion piece 9 and the protrusion 11. It fits into the recess 13 at the center of the tip.

１４は左右の分岐片３，４の基部表面に設けた補強用突
出部である。Reference numeral 14 denotes reinforcing protrusions provided on the base surfaces of the left and right branch pieces 3 and 4.

第３図は合成樹脂板製発射台の別の実施例を示す。FIG. 3 shows another embodiment of the launch pad made of synthetic resin plate.

この考案においては第１図に示すようにこま体８の心棒
１２を発射台１の前方中央に形成する凹部１３内に嵌合
すると共に突片１０と発射台１の右分岐片４との間に輪
ゴムＡを張設し、突片９を左分岐片３に接続する移動片
６の裏面突起１１に係止させた後に、左右の分岐片３，
４を指先きで切欠２側に向は押すと、左分岐片３に接続
する移動片６は合成樹脂板の弾力により外側に開らき突
片９と突起１１との係止状態を解く。In this invention, as shown in FIG. Stretch a rubber band A to the left and right branch pieces 3, after locking the protrusion piece 9 to the back protrusion 11 of the movable piece 6 that connects the left branch piece 3,
4 toward the notch 2 side with a fingertip, the movable piece 6 connected to the left branch piece 3 opens outward due to the elasticity of the synthetic resin plate and releases the engagement between the protruding piece 9 and the protrusion 11.

従って輪ゴムＡは急激に縮少しこま体８の心棒１２は発
射台１の凹部１３よりはずれてこま体は前方に飛び出し
て矢印方向に回転する。Therefore, the rubber band A is rapidly contracted, the spindle 12 of the top body 8 is disengaged from the recess 13 of the launch pad 1, and the top body jumps forward and rotates in the direction of the arrow.

このように、この考案によるときは、単に左右の分岐片
３，４を指先きて発射台１の軸線方向に押すと、輪ゴム
Ａの復元力によりこま体８は確実に合成樹脂板製の発射
台より飛び出して回転する、という効果を生ずる。In this way, when using this invention, if you simply push the left and right branch pieces 3 and 4 in the axial direction of the launching platform 1 with your fingertips, the restoring force of the rubber band A will ensure that the top body 8 will be able to release the launching pad made of synthetic resin plate. This produces the effect of jumping out from the table and rotating.
