REVERSE RUN PREVENTION DEVICE
PROBLEM TO BE SOLVED: To provide a reverse run prevention device capable of physically preventing reverse run of a vehicle.SOLUTION: A reverse run prevention device comprises: a receiving frame 1 with pot-shaped cross section, which is installed on a road surface in a direction perpendicular to a vehicle travel direction; a cover plate 2, which is laid across the receiving frame 1 so as to be flush with the road surface; a long groove-shaped cutout 3, which is formed at predetermined intervals on the cover plate 2; and a reverse run prevention plate 6, which is pivotally supported by a shaft 5 under the cover plate. The reverse run prevention plate 6 has a ballast 7 at the lower end and always energizes the reverse run prevention plate 6 so as to rotate in counterclockwise direction and presses the plate against the cutout end and makes the upper side part protrude from the cover plate 2. As the reverse run prevention plate 6 butts against the cutout end even if a tire 9 collides against the reverse run prevention plate 6 that protrudes from the cover plate 2 when the vehicle runs in reverse direction, the reverse run prevention plate is prevented from rotating, which increases a deterrent against reverse run.SELECTED DRAWING: Figure 4
【課題】車両の逆走を物理的に阻止することができる逆走防止装置を提供する。【解決手段】路面に車両の進行方向と直交して設置される鍋形断面の受枠１と、受枠１に掛け渡して路面と面一をなして設置されるカバープレート２と、カバープレート２に一定間隔ごとに形成される長溝状の切欠き３と、カバープレート下の軸５に軸支される逆走防止プレート６よりなり、逆走防止プレート６は下端部にバラスト７を有して常には逆走防止プレート６を反時計方向に回転するように付勢して切欠き端に押付け、上側部をカバープレート２より突出させる。逆走時にタイヤ９がカバープレート２より突出する逆走防止プレート６に衝突しても切欠き端に当たる逆走防止プレート６は回転が阻止され、逆走への抑止力を高める。【選択図】図４
