GRATING WITH JUMPING PREVENTION MECHANISM
PROBLEM TO BE SOLVED: To provide a grating with a jumping prevention mechanism, capable of preventing a grating that is placed on a road gutter or the like from being made to jump by a vehicle or the like for displacement and scattering.SOLUTION: On a rear surface of a grating body 1, a jumping prevention mechanism 2 is attached which includes a disc-like cam 4 provided with an arc-like or helical guide groove 3, and a lock pin 5 which is guided by the guide groove 3 so that a tip end is protruded outward. The disc-like cam 4 is rotated to make the lock pin 5 protrude. A tip end of the lock pin 5 is made to enter a hole part 21 formed on a gutter 20 so that jumping of the grating body 1 is prevented.SELECTED DRAWING: Figure 1
【課題】道路側溝などに敷設されているグレーチングが、車両等によって跳ね上げられてズレたり飛散したりするのを防止することができる跳ね上がり防止機構付きグレーチングを提供する。【解決手段】グレーチング本体１の裏面に、円弧状あるいは螺旋状の案内溝３を設けた円板状カム４と、前記案内溝３にガイドされて先端を外方向へ突出自在としたロックピン５を有する跳ね上がり防止機構２を取り付け、前記円板状カム４を回動してロックピン５を突出させ、ロックピン５の先端を側溝２０に形成した孔部２１に嵌入することによってグレーチング本体１の跳ね上がりを防止するようにした。【選択図】図１
