PORTABLE BARRICADE FOR VEHICLE ENTRY PREVENTION
To provide a portable barricade for vehicle entry prevention capable of securing safety without damaging fingers and the like by eliminating a pinching action between members which are mutually folded.SOLUTION: A portable barricade for vehicle entry prevention having a central axis that is horizontal when installed, a plurality of first protrusions arranged apart from one another on the axis of the central axis and maintained in parallel with one another, and a plurality of second protrusions arranged apart from one another on the axis of the central axis and in a parallel relationship adjacent to each of the first protrusions, and also in an expanded state intersecting in an X shape when viewed from one side, the portable barricade further having folding and holding means capable of holding both the first and second protrusions in a parallel folded state, and expanding and holding means capable of holding the first and second projecting materials in an expanded state intersecting in an X shape when viewed from the side. The interval between the first and second projecting members is configured so that rotation braking is possible by pre-folding temporary rotation braking means at least at an intermediate angle at which the X-shaped expanded state when viewed from the side view is shifted to the folded state.SELECTED DRAWING: Figure 2
【課題】互いに折り畳まれる部材間での挟み作用をなくすことによって手指などに損傷を与えず安全性が確保されるようにし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と、中心軸の軸上に離れて配置され互いに平行関係を保って設けられた複数本の第１突材と、中心軸の軸上に離れて配置され各第１突材と隣り合う平行関係とされる一方側面視Ｘ字状に交差した拡開状態にもなるようにされる複数本の第２突材とを有するとともに、第１・第２の両突材を平行な折畳状態に保持可能な折畳保持手段と、第１・第２の両突材を側面視Ｘ字状に交差した拡開状態に保持可能な拡開保持手段とを有する可搬型車両進入阻止用バリケードにおいて、第１・第２両突材間は、側面視Ｘ字状の拡開状態から折畳状態に移行する少なくとも中途角度において折畳前一時回転制動手段にて回転の制動が可能に構成されていることを特徴とする。【選択図】図２
