できるようにする車両侵入防止柵に関する。[Detailed Description of the Invention] This invention provides an entrance/exit to a park, an entrance/exit from a public road to a private road,
This invention relates to a vehicle intrusion prevention fence that is installed at the entrance and exit of a parking lot, and normally prevents unauthorized entry of vehicles, but also allows vehicles to pass through at different times of the day or in an emergency.
従来、この種の車両侵入防止柵としては、例えば、人や

間隔で柵を路面に立設固定したものや、地中にあるいは
地中から柵を出没させるようにしたものや、予め路面側
に設けられた設置溝や設置穴に柵を着脱可能に嵌合設置
するようにしたもの等が知られている。Conventionally, this type of vehicle intrusion prevention fence has been constructed by installing and fixing the fence on the road surface at intervals that allow people and bicycles to pass through but not allowing vehicles to pass through, or fences built underground or underground. Some are known in which the fence is made to appear and disappear from the ground, and others are in which the fence is removably fitted into installation grooves or installation holes provided in advance on the road surface.

いずれも満足できるものではなかった。However, with these conventional vehicle intrusion prevention fences, even if an emergency such as a fire occurs and it is necessary for vehicles such as fire engines to pass, these vehicles may not be able to pass, or they may be forced to pass. If it was necessary to do so, the fence would have to be torn down, making it impossible to respond to emergencies. Installation work such as burying the guide tube that guides the vertical slide can cause sand, pebbles, dirt, rainwater, etc. to get into the guide tube and accumulate.
In addition to problems such as the inside of the guide cylinder becoming clogged and rusting, which interfered with the movement of the fence, there were also cases where people ran away with the fence, and people who ran away with the fence became troublesome to move the fence and were thrown into the end. Conventional vehicle intrusion prevention fences have been unsatisfactory in all of these problems, such as the fences being left unattended and no longer functioning as a fence.
