DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is normally used along the side of a sidewalk facing a road and used for protecting pedestrians and guiding walking. In an emergency due to an earthquake or fire, the present invention is applied to a road. The present invention relates to a vehicle entry prevention fence that can protrude to prevent traffic of a vehicle and perform traffic control.

[0002]

2. Description of the Related Art Conventionally, in the event of an emergency such as a fire, a rope or the like is put on the site to prohibit entry of unrelated persons. Further, in order to detour a pedestrian or a traveling vehicle at the time of road construction or the like, a simple conical stand type fence made of soft rubber or synthetic resin is used.

[0003]

In the event of an emergency such as the above-mentioned earthquake or fire, it is necessary to restrict ordinary vehicles running on the road to secure a passage or an evacuation road for emergency vehicles and vehicles for transporting emergency supplies. is there. For this purpose, it is necessary to install a fence for preventing vehicles from entering the road, but in order to be able to make it in case of an emergency, related parties can easily install the device at a predetermined position as needed in a short time. together, it is necessary to ensure that does not cause confusion to release the arbitrarily entry restriction by moving the entry prevention fence that was installed easy to the general public other than the parties, moreover, as soon as necessary parties This entry barrier must be removable.

[0004] prevention of the entry due to Russia-loop in a fire that was said is, those which are used as entry prevention measures against the people, not very useful to the entry prevention with respect to the vehicle. In addition, it is necessary to carry a predetermined number of the stand-type fences used for road construction and the like to the site,
The time loss for this cannot be overlooked, and even if it is installed , it may be easily removed and confused unless it is monitored on site.

[0005] It is an object of the present invention, at the time of flat, along with the exhibits utility in the safety and induction of pedestrians, traffic of vehicles traveling on the roadway in the occurrence of an emergency, such as the above-mentioned earthquake and fire It is an object of the present invention to provide a vehicle entry prevention fence capable of easily blocking a vehicle by blocking the vehicle.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The vehicle entry prevention fence of the present invention is of various modes as will be described later in embodiments. The material of this vehicle entry prevention fence is made of stainless steel, aluminum, iron, or the like. Can be made by metal. It is desirable that the vehicle entry prevention fence be locked so that anyone other than the relevant person cannot easily perform the operation of preventing the entry of the vehicle, and if necessary, a notice of the entry prevention is posted on the fence. It is desirable.

[0012]

The fence for preventing vehicle entry according to the present invention is usually arranged along the sidewalk near the side of the road and serves as a guide and protection for pedestrians walking on the sidewalk, so that they do not obstruct traffic, and once an earthquake occurs. In the event of a fire, fire or other emergency, the vehicle's entry fence can be moved in a direction perpendicular to the sidewalk to block the traffic of vehicles running on the road and prevent the vehicle from entering quickly and easily. Thus, it is possible to adjust the level difference between the sidewalk and the roadway when moving perpendicular to the roadway, and it is possible to sufficiently adapt to this when there is no level difference between the sidewalk and the roadway.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below more specifically with reference to the accompanying drawings. 1 and 2 show an example of a vehicle entry prevention fence of the present invention.
Is formed with a concave portion (not shown) at the lower end surface of the column 33, 34 of the fence main body 32 obtained by connecting the columns 33, 34 at both ends with horizontal rails 35, 36, and the concave portion is formed on the road B side. A pair of buried pipes 37, 38 protruding along the sidewalk A that has been fitted are placed in the sidewalk A and used as a protective fence for the sidewalk A, and the fence body 32 itself is removed from the buried pipes 37, 38 as necessary. The vehicle is separated and carried to the road B to prevent the vehicle from entering. Vehicle entry prevention fence 31 of this structure
Does not require a structure for extending and retracting columns, and can be manufactured at a very low cost.

FIGS. 3 and 4 show another embodiment of the vehicle entry prevention fence of the present invention. The vehicle entry prevention fence 41 is composed of a fixed support 43 having a square cross section and a movable support 4 having a square cross section.

The stop fences 81a and 81b and the small fence 82 are normally arranged facing the sidewalks A and A on the side of the road B as shown in FIG. The moving supports 83a and 83b are arranged orthogonally to the road B, and a small fence 82 is arranged between the two to block the wide road B.

FIG. 10 shows still another embodiment of the vehicle entry prevention fence of the present invention. The vehicle entry prevention fence 91 is erected by embedding the lower end thereof at a predetermined interval on the sidewalk facing the roadway side. A pair of support pipes 92a and 92b and a pair of pivot pipes 94a and a movable pipe 94b which are detachably fitted to the support poles 92a and 92b, respectively.
5 and 95 are connected to each other, a fence 93 is formed by the pivot pipe 94a, the moving pipe 94b, and the horizontal rails 95 and 95, and the pivot pipe 94a and the moving pipe 94b are fitted to the respective posts 92a and 92b. It is. This fence body 9
3 is lifted upward and the pivot pipe 94a and the moving pipe 9
4b can be separated by detaching them from the columns 92a and 92b.

A caster 96 with a stopper is attached to the lower end of the moving pipe 94b, and the caster 96 contacts the side surface of the level x to maintain the height of the fence 93, and is fitted to the support post 92a and the outside thereof. The pivot pipe 94a is also held at the same level. In this state, the support 92
a and a pivot pipe 94a externally fitted thereto prevent vertical movement and rotation of the fence body by a fixing bolt 97 penetrating both.
The tip of the penetrating fixing bolt 97 is locked at the front end 98, and a flange provided at the lower end of the moving pipe 94b and the support 9
2b is locked with a lock 99 via a chain so that only a specific person can release it.

Then, these locks are released, the fixing bolts 97 are pulled out, the fences 93 are lifted, and the columns 92 are lifted.
a, 92b, and then a pivot pipe 94a is fitted into the support 92a, and the fence 93 is rotated in the horizontal direction about the support 92a to move the moving pipe 94b to the level x.
Is operated so as to protrude on a road with a level y lower than that of the sidewalk. As a result, the caster 96 at the lower end of the other moving pipe 94b comes into contact with the level y road surface, and
The bar 93 can be supported in a horizontal state at a position lower by the height h with the upper end of a abutting against the inner part of the pivot pipe 94a. The vehicle entry prevention fence 91 has a fence body 93.
The display of "vehicle closing", a closing mark, the signature of the police in charge, the name of the government office, etc. as a panel can greatly contribute to preventing vehicles from entering during disasters such as earthquakes and fires.

[0022]

The fence for preventing vehicle from entering according to the present invention is normally disposed along the sidewalk near the roadway without obstructing traffic, and serves as a protection and guide for pedestrians walking on the sidewalk, Once an earthquake, fire, or other emergency occurs, move the vehicle entry fence in a direction perpendicular to the sidewalk to shut off traffic on the road and prevent the vehicle from entering quickly and easily. It can adjust the level difference between the sidewalk and the roadway when moving perpendicular to the roadway, and can be fully adapted to this when there is no level difference between the sidewalk and the roadway. is there.
