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,
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 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 and bicycles but not allowing vehicles to pass, or by installing the fence in the ground or from underground. Some are known in which the fence appears and disappears, and others are known 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 may have to force their way through. In some cases, the fence has to be taken down, making it impossible to respond to emergencies, and in other cases, a vertical hole with a depth equal to the height of the fence is bored in the road surface to guide the vertical sliding of the fence. Installation work such as burying guide tubes for fences may be difficult, or sand, pebbles, dirt, rainwater, etc. may get into the guide tubes and accumulate, causing clogging or rusting inside the guide tubes, causing the fence to disappear. In addition, if the fence is stolen and the fence is relatively heavy, it becomes troublesome to move the fence and the fence is left hanging on the tangled ends. Conventional vehicle intrusion prevention fences have not been able to satisfy either of these problems.

In view of the above, the present invention provides an intrusion prevention body made of a rod or a plate, a support rod whose one end is connected to the intrusion prevention body, and a lower end of the intrusion prevention body rotatably connected. A vehicle intrusion prevention fence is formed by a support bracket that removably engages the lower end of the support rod, and normally prevents unauthorized vehicle intrusion, but also acts as an intrusion prevention body depending on the time of day or in an emergency. By folding the support rods into a laid-down state, vehicles can pass through, which solves all of the above-mentioned problems with conventional vehicle intrusion prevention fences.In addition, when in use, the upright state is firmly maintained, reducing the overall impact of the fence. To provide a foldable vehicle intrusion prevention fence with high strength.

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

1 to 4, a foldable vehicle intrusion prevention fence A according to the present invention is shown.

This vehicle intrusion prevention fence A has an intrusion prevention body 1 formed by connecting the upper and lower ends of two rods having a predetermined gap 8 with each other by rotating shafts 5a and 5b, respectively. The upper end of a support rod 2 formed of a single rod material is rotatably connected to the provided rotating shaft 5a, and the rotating shaft 5b provided at the lower end of the intrusion prevention body 1 is connected to the road surface G. The bearing part 6 of the fixed support bracket 3 is rotatably connected, and a locking rod 7 is provided at the lower end of the support rod 2, and the locking rod 7 is formed in the upper surface of the holding bracket 4a in an engaging recess 4b. The intrusion prevention body 1 is held in an upright state by being removably engaged with the support rod 2 and the holding bracket 4a, and
By releasing the lock to this holding bracket 4a, the connecting portion J between the upper end of the intrusion prevention body 1 and the upper end of the support rod 2
□ and the connecting part J2 between the lower end of the intrusion prevention body 1 and the support bracket 3 are rotated to fold the intrusion prevention body 1 and the support rod 2 into two and fold them into a lying state on the road surface G. It was designed so that

In this embodiment, the rod material forming the support rod 2 is the same as the rod material forming the intrusion prevention body 1;
The gap 8 between each of the rods is large enough to fit the support rod 2, so that a part of the support rod 2 will fit into the gap 8 when the two are folded onto each other. ing.

Further, the holding bracket) 4a is an anchor part 28 buried underground and is formed integrally with the support bracket 3.
As shown in the figure, when a plurality of vehicle intrusion prevention fences A are installed side by side, the distance between the bearing part 6 of the support bracket 3 and the holding bracket 4a in each vehicle intrusion prevention fence A varies, resulting in a state in which the vehicle intrusion prevention fence A stands upright. This prevents the heights of the intrusion prevention body 1 and the support rod 2 from becoming uneven.

Therefore, according to the foldable vehicle intrusion prevention fence A of the present invention,
For example, as shown in FIG. 1, the intrusion prevention body 1 is installed facing forward on the road surface G of the entrance/exit from a public road to a private road, and when it is in use, the intrusion prevention body 1 is supported by the support rod 2 and the holding bracket 4a. The intrusion prevention body 1 and support rod 2 of this vehicle intrusion prevention 111+A are shown by solid lines in FIG. The fences are folded into a lying state so as to overlap each other, and vehicles can pass by climbing over the vehicle intrusion prevention fence A folded into this lying state.

This vehicle intrusion prevention fence A may be used alone or may be installed in multiples as shown in Figure 1, taking into account the conditions of the road surface G, etc. As shown by the imaginary line in Fig. 5, the vehicle intrusion prevention fence A is installed with the side face facing the front of the entrance/exit, and when not in use, the intrusion prevention body 1 and the support rod 2 are installed as shown by the solid line in Fig. 5. It is also possible to extend it in a straight line and fold it into a lying position on the road surface G so that a vehicle can pass over this vehicle intrusion prevention mA.

As mentioned above, the foldable vehicle intrusion prevention fence according to the present invention is
The upper end of the support rod is rotatably connected to the intrusion prevention body, and the lower end of the intrusion prevention body is rotatably connected to a support bracket fixed to the road surface, and the locking rod of the support rod is removably engaged. The intrusion prevention body is held in an upright state by being held by the engagement recess of the retaining bracket to which the intrusion prevention body is attached, and by releasing the lock between the locking rod and the engagement recess, the intrusion prevention body and the support rod are placed on the road surface. Since it can be folded into a lying position, it can be installed at entrances to parks, entrances from public roads to private roads, entrances to parking lots, etc., and can usually be used to prevent unauthorized entry of vehicles, and depending on the time of day. Alternatively, in an emergency, the holding means can be released and the intrusion prevention body and support rod can be folded onto the road surface to allow vehicles to pass, and the lower end of the intrusion prevention body can be firmly attached to the road surface via the support bracket. When in use, the lower end of the support rod engages with the engagement recess of the holding bracket and is firmly held, so even though it is a foldable structure, the entire fence is It has the feature of high strength, and furthermore, there is almost no risk of someone running away with the fence or being left unattended, and it also has the advantage of being highly durable, and it also has the advantage of being highly durable, and there is also no risk of the fence being left unattended or left unattended. There are no problems seen with the intrusion prevention fence.

In addition, the engagement between the locking rod of the support rod and the engagement recess of the holding bracket can be easily released by pushing the intrusion prevention body against the opposite force, so in an emergency, by pushing it down, it will lie flat on the road surface. It can be folded up and can be used immediately.
