Description

[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,
The present 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 depending on the time of day or in an emergency.

Traditionally, this type of vehicle intrusion prevention fence has been constructed by installing and fixing the fence on the road surface at intervals that allow the passage of people, bicycles, etc. 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.

However, with these conventional vehicle intrusion prevention fences, even if an emergency such as a fire occurs and vehicles such as fire engines need to pass, these vehicles may not be able to pass, or they may be forced to pass. If necessary, the fence would have to be taken down, making it impossible to respond to emergencies, or a vertical hole with a depth equal to the height of the fence could be drilled in the road surface to remove the top and bottom of the fence. Installation work such as burying a guide tube to guide the direction slide may become a chore, or sand, pebbles, dirt, rainwater, etc. may get into the guide tube and accumulate, causing clogging and rusting inside the guide tube. There is a problem that the fence interferes with the movement of the fence, and furthermore, the fence can be taken away and moved, and moving the fence becomes troublesome and the fence is left on the tangled edges and no longer fulfills its role as a fence. There are various problems, and conventional vehicle intrusion prevention fences have not been able to satisfy any of them.

In view of this point of view, the present invention enables a gutter body having a plurality of legs to be folded down on the spot,
To provide a foldable vehicle intrusion prevention fence that can be folded to allow vehicles to pass over, straddle, or avoid the gutter body, thereby solving the above-mentioned problems all at once. .

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

1 to 3, a foldable vehicle intrusion prevention fence A according to a first embodiment of the present invention is shown.

This vehicle intrusion prevention fence A has a gutter body 1 with two legs 2.
a, 2b and one horizontal part 3, and the upper ends of each leg part 2a, 2b are rotatably supported by shaft pins 4 at both ends of the horizontal part 3, and are buried in the road surface G. 2@ bracket) 5a.

5b is fitted to the lower end thereof to maintain the upright state.

As shown in FIG. 2, the bracket 5a is formed with an inward 7 flange portion 10 protruding from the upper end of a cylindrical body with an open upper end.
The lower end of one leg 2a, to which a slider 9 is rotatably connected by a shaft pin 7, is slidably fitted into the racket 5a (7) 7'.

Therefore, in the upright state shown in FIG.
By pulling up a until the flange portion 9a of the slider 9 and the inward flange portion 10 of the bracket 5a come into contact, the shaft pin 7 is exposed on the road surface G and the leg portion 2a is rotated around the shaft pin 7. Can be bent.

Further, as shown in FIG. 3, the bracket 5b is formed of a cylindrical body with an open upper end, and the lower end of the leg portion 2b is open.

Bracket the 7-rank portion 11 formed on the leg portion 2b) 5
While in contact with the upper end of the bracket Sb, it is removably fitted into the bracket Sb and maintained in its upright position.

Therefore, according to the foldable vehicle intrusion prevention fence A according to the present invention, it is installed, for example, at the entrance/exit from a public road to a private road, and normally prevents unauthorized vehicle intrusion, and when it becomes necessary for vehicles to pass. It can be folded on the spot, as shown by the imaginary line, to free up space for vehicles to pass through.

That is, in order to fold the container body 1, as shown in FIG.
A bracket 5a whose lower end portions a and 2b also serve as support means 8a and 8b.

5b, rotate the other leg 2b about 180 degrees about the axis of one leg 2a in the direction indicated by the arrow, and then rotate each leg 2a, 2b and the horizontal part around the axis of the shaft pins 4 and 7. 3 in the direction of arrow C, and fold the container body 1 to the outside of one leg 2a in a lying state as shown by the imaginary line.

At this time, by arranging the shaft pin 4 and the shaft pin 7 so that their axes are perpendicular to each other,
2b and the horizontal portion 3 are both folded so as to be in contact with the road surface G, and the height at which the container body 1 projects from the road surface G in the folded state can be reduced.

FIGS. 4 and 5 are explanatory diagrams showing a modification of the lower end portion of one leg 2a in the present invention.

In this modification, the means for connecting the lower end of the leg portion 2a and the slider 9 is not the shaft pin 7, but a bendable connecting cable 12 such as a chain or wire, and furthermore, the means for connecting the lower end of the leg portion 2a and the slider 9 is A flange portion 11 provided at the lower part of the portion 2a is formed into a cap shape that covers and locks the upper end of the bracket 5a.

Therefore, according to the vehicle intrusion prevention fence A according to this modification,
There is no directionality in the bending of the connecting cable 12 as in the case of connecting with the shaft pin 7, and the main body 1 is simply folded so that one of the legs 2a and the horizontal part 3 are folded over each other. Since the horizontal part 3 rotates approximately 90 degrees to a more stable state in the folded state, that is, to a state in which the horizontal part 3 also touches the road surface G,
The protrusion height of the container body 1 from the road surface G in the folded state can be minimized.

Also, ensure a sufficient length of the connecting cable 12, and when the main body 1 is in its upright state, connect the connecting cable 12 to the bracket 5a.
When the container body 1 is folded, the connecting cable 12 is pulled out from inside the bracket 5a, and the container body 1 is moved to a 5-way end where it does not obstruct the passage of vehicles, and then folded. Furthermore, when the main body 1 is in use, the flange portion 11 formed in a cap shape covers the upper end of the bracket 5a to prevent sand, pebbles, dust, rainwater, etc. from entering into the bracket 5a. It can be completely prevented.

However, the means for bendably locking one leg 2a to the bracket 5a in the present invention is not limited to the above-mentioned one, and the means for bendably locking the one leg 2a to the bracket 5a is not limited to the above-mentioned method. The lower end portion of the leg portion 2a may be connected to the lower end portion of the leg portion 2a by a shaft pin 7.

Further, in the embodiment described above, two brackets 5a
, 5b are integrally connected by the bracket substrate 13, but the present invention is not limited to this, and may be formed individually.

As described above, the foldable vehicle intrusion prevention fence of the present invention has each leg portion and the horizontal portion divided, and the upper end of each leg is rotatably supported by the horizontal portion, and at least one of the leg portions is rotatably pivoted. The lower end of one leg is foldably locked to the bracket, and the lower end of the other leg is removably fitted to the bracket, so pull the other leg out of the bracket and bend it in the opposite direction. By folding the container, the main body of the container will not be trampled by vehicles when passing by, and the main body of the container can always be kept beautiful.

Also, one leg is locked to the bracket, so
There is almost no risk of the vessel being carried away or being left on the tangled ends, and furthermore, there is no need for extensive installation work, as would be the case if the vessel was to be placed in or out of the ground. It is extremely useful as a vehicle intrusion prevention fence installed at park entrances, entrances from public roads to private roads, parking lot entrances, etc.
