JP3123682U - Telescopic vehicle entry barrier - Google Patents

Abstract

PROBLEM TO BE SOLVED: The blocking fence of the present invention has an effect capable of physically blocking the entry of a vehicle or the like into a restricted area mainly required by a security authority in an emergency,
The object is to have an extremely simple structure, which can be transferred at an early stage, and that the fence body can be easily expanded and contracted.
[MEANS FOR SOLVING PROBLEMS] In the case of emergency deployment mainly by security authorities, the present invention temporarily blocks the passage of vehicles, etc. in a restricted area, blocks the roads, etc. over a wide area at an early stage, and additionally advances the vehicle. It can be physically blocked, and the means is to implement the expansion and contraction of the fence body by the opening mechanism and the attractive force of the winding drum of the wire rope.

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 barrack-like 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 the reckless and illegal vehicle from breaking through the barricade. The objective is to obtain a barrier that makes it impossible to proceed.

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 large barrier wheel on the main pillar can be landed, and a barricade can be constructed instantly with just one worker by simply swiping the handle, and a blocking fence that can forcibly and physically stop vehicles recklessly approaching It 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 to allow it to expand and contract freely. A chain that is fixed to a chain provided with a ring that determines the width of expansion when the blocking fence is extended to the upper part of the one crosspiece (1) and the other crosspiece (2). The wire rope (6) winding drum (5) provided on the upper part of the crosspieces via the chain-opening mechanism (4) provided to the connecting rod (3) at one end by fixing the cable (6) to the one connecting rod (3). ) Is installed horizontally.
In other words, the blocking fence is always retracted and contracted by the winding force of the wire rope (6) accommodated on the winding drum (5), and the pressing piece of the chain opening mechanism (4) is expanded. Can be stretched and expanded to a predetermined width.

  The retractable vehicle barrier fence of the present invention is a part of the security product that the applicant has developed over the years as a business.

These are the principal part explanatory drawings which the vehicle entrance prevention fence of this invention extended.
