PORTABLE VEHICLE APPROACH INHIBITION BARRICADE
To provide a portable vehicle approach inhibition barricade achieving downsizing and safety of an instrument.SOLUTION: A center shaft 1, which is set in a horizontal direction when installed and used, is formed of a cylindrical base shaft 2 and a telescopic shaft 3 which is expandable/contractible in the axial direction with respect to the base shaft 2. A set of two protrusion members 8, 10 are arranged at both axial ends of the base shaft 2 and the end on the expansion side of the telescopic shaft 3. The protrusion members 8, 10 have the center shaft 1 passed through the intermediate positions thereof and are connected by an expandable/contractible connecting member 20 so as to rotate together while maintaining a parallel relationship. A portable vehicle approach inhibition barricade comprises: folding/holding means capable of holding the protrusion members 8, 10 in a parallel folded state; expanding/holding means 40 capable of holding the protrusion members 8, 10 in an expanded state crossed in an X shape in a side view; coming-off preventing means 24 for regulating the expanding/contracting protrusion members 8, 10 in a certain expanded state; and contracting/holding means 30 capable of holding the protrusion members contracted in the axial direction while folded in a contracted state. Moving casters 46 are provided in lower parts of the protrusion members including the expandable protrusion members 8, 10.SELECTED DRAWING: Figure 5
【課題】器具のコンパクト化と安全性を備えた可搬型車両進入阻止用バリケードを提供する。【解決手段】設置使用時水平向きとされる中心軸１は、筒状の基軸２とその基軸２に対しその軸方向に伸縮可能な伸縮軸３とでなり、基軸２の軸方向両端と伸縮軸３の伸展側の端部には、２本１組の突材８、１０がそれぞれ配備され、両突材８、１０は、その中間位置に中心軸１が通されて互いに平行関係を保って回転するように伸縮可能な連結材２０により連結されるとともに、両突材８、１０を平行な折畳状態に保持可能な折畳保持手段と、両突材８、１０を側面視Ｘ字状に交差した拡開状態に保持可能な拡開保持手段４０と、伸縮する両突材８、１０を一定の伸展状態に規定する抜け止め手段２４と、折畳状態で軸方向に縮小した両突材を縮小状態に保持可能な縮小保持手段３０とが設けられ、伸展可能な両突材８、１０を含む突材の下部には、移動用キャスタ４６が配備されている。【選択図】図５
