Description

  The present invention relates to a telescopic fence body that forcibly and physically blocks a vehicle used by an illegal person such as a terrorist.

In the case where the traffic regulation of the conventional security authorities is performed, the passage of the corresponding vehicle or the like is regulated by installing a horseshoe-shaped barricade or a weight cone on the road.
Recently, various barriers have been developed to prevent the breakthrough of barricades caused by special emergency guards or violent crimes, and they are effectively used when they are installed in a certain place for a certain period of time. However, each of the above-described blocking fences has a heavy and sturdy structure in consideration of a forcible breakthrough by a large vehicle.
As described above, a light and simple barricade that is simply installed on the road can easily break through even in a small vehicle, and a sturdy and heavy barricade has a large amount of mobility to transport the barricade. A number of officers were required to perform extremely troublesome work such as having to unload and unload the vehicle from the loading platform.
Problems that the device tries to solve

In view of the above reasons, the present invention is light and easy to transport in order to prevent reckless and illegal vehicles from breaking through barricades, and is quickly barricade even on sloping road surfaces such as hills. It is an object to obtain a blocking fence that makes it impossible to progress.
Means for solving the problem

  The barrier (barricade) is a well-known and extremely compact foldable accordion type used for garages and entrances. It is loaded on a transfer vehicle and is unloaded from the rear of the vehicle to the road surface. A barricade that can instantly build a barricade with just one worker by simply landing a large sliding wheel of the main pillar and cleverly pulling the handle, forcing and physically stopping a vehicle that is planning reckless entry Is to provide.

  When this blocking fence is loaded on a transfer vehicle, one side of the large sliding wheel of the blocking fence is lowered to one side edge of the road surface where traffic is blocked at the site of the restricted area and the handle is extended, the blocking fence is extended. The wire rope winding device and the chain opening mechanism that can be freely braked extend only an arbitrary length and can be installed and deployed according to the required road surface width.

The present invention will be described below with reference to the accompanying drawings.
The morphological characteristics of the present invention are such that a hollow steel material made of special steel is used for a part of the material, and a hollow steel material made of ordinary iron is used for the other part as a main material, and has a predetermined length in a cross-beam shape. In order to make the elongated steel rail into a two-piece one rail (1) and the other rail (2) as a linkage, through-holes of the same shape are drilled in the upper, middle and lower parts of the rail. A plurality of connecting rods (3) in which both ends of an iron round bar having a predetermined length are threaded into the through-holes are used for the upper part, the central part and the lower part of the above-mentioned one-sided crosspiece. It is pivotally attached to the through hole, and is also pivotally attached to the other crosspiece of the double body so that it can freely expand and contract. be one obtained by fixing a chain having a ring to adjust, wire rope which determines the developed width of the elongation at the present blocking fence (6), the one end of the blocking fence Secured to the connecting rod end (3), wire rope (6) provided in the upper position of the both桟体via open-chain mechanism (4) provided on the connecting rod of the other end of the blocking fence winding drum (5 ) to one in which was housed.
That is, the blocking fence is always retracted and contracted by the winding force of the wire rope (6) accommodated in the winding drum (5), and when it is installed, the chain opening mechanism (4 ), The handle of the opening mechanism (4) that presses the wire rope (6) is expanded, and can be expanded and expanded to a predetermined deployment width. is there.

  The telescopic vehicle blocking fence of the present invention is a part of the security equipment that the applicant has developed over the years as a business.

These are the principal part explanatory views which extended the vehicle approach prevention fence of this invention.
