TRANSPORTABLE BARRICADE FOR BLOCKING APPROACHING VEHICLE
PROBLEM TO BE SOLVED: To provide a transportable barricade for blocking an approaching vehicle that may be folded compactly into a flat frame, thereby allowing a series of work from transportation to an installation site to carrying back to be performed readily and without a physical damage.SOLUTION: A transportable barricade for blocking an approaching vehicle includes a plurality of projection materials 5 for an outer shaft 1 that are installed and fixed in parallel to each other at a plurality of locations separated along a longer-side direction of the outer shaft 1, with an intermediate part of the projection material in a longer-side direction inserted into the outer shaft 1. A plurality of projection materials 6 for an inner shaft 2 are disposed in parallel to each other in a number corresponding to the projection materials 5 for the outer shaft, the projection material 6 for the inner shaft being connected on the inner shaft 2 side and having an intermediate part in a longer-side direction thereof inserted into the outer shaft 1 in a way that allows forward/backward motions in an axial direction and rotation. The projection materials for the outer shaft and the inner shaft may be switched between adjacent folded state and expanded state by a folding or expanding operation through energizing means, the projection materials arranged in a shaft-form that are parallel to each other, around the outer shaft. The projection materials 5 for the outer shaft may be disengaged from the projection materials for the inner shaft when external force that resists the energizing means is exerted, to return to the folded state.SELECTED DRAWING: Figure 9
【課題】折畳式で平枠コンパクト化することができることにより、現場への搬送から設置ならびに持ち帰りまでの一連の作業が簡易かつ身体損傷なく行える車両進入阻止用可搬型バリケードを提供する。【解決手段】その長手中途が外軸１に挿通された状態で外軸１の長手方向に離間した複数個所に互いに平行をなす関係で固定配備され、内軸用の突材６は、内軸２側に連結されてその長手中途が外軸１に対し軸方向に進退と回転が可能に挿通された状態で外軸用の突材５と対応する複数本で構成されて互いに平行をなす関係で配備されるとともに、外軸用と内軸用の突材は、外軸回りにおいて互いに平行軸状をなすように付勢手段を介して隣接する折畳状態と拡開状態との２つの状態に折畳および拡開各操作により切換可能で、付勢手段に抗した外力の付与により内軸用と外軸用突材５の咬み合いを解除し折畳状態に復帰可能に構成されていることを特徴とする。【選択図】図９
