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 through at different times of the day or in an emergency.

Conventionally, this type of vehicle intrusion prevention fence has been constructed by installing and fixing the fence on the road surface at intervals that allow people and bicycles to pass through 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 it is necessary for vehicles such as fire engines to pass, these vehicles may not be able to pass, or they may be forced to pass. If it was necessary to do so, the fence would have to be torn down, making it impossible to respond to emergencies. Installation work such as burying the guide tube that guides the vertical slide can cause sand, pebbles, dirt, rainwater, etc. to get into the guide tube and accumulate.
In addition to problems such as the inside of the guide cylinder becoming clogged and rusting, which interfered with the movement of the fence, there were also cases where people ran away with the fence, and people who ran away with the fence became troublesome to move the fence and were thrown into the end. Conventional vehicle intrusion prevention fences have been unsatisfactory in all of these problems, such as the fences being left unattended and no longer functioning as a fence.

In view of this point of view, the present invention includes forming a removable connecting portion on the horizontal rod of the vessel body, and erecting bendable support legs to lock the connecting portion of the horizontal rod. By holding it in a state of use that prevents the passage of vehicles, and releasing the locking of the connecting portion, the horizontal rod and the bendable support legs can be folded into a stored state that allows vehicles to pass. Thus, the present invention provides a foldable vehicle intrusion prevention fence that can solve all of the above-mentioned problems at once.

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

1 and 2, 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 one support leg 2a whose main body 1 is erected on the road surface G, and the other support leg whose lower end is bendably connected to a bracket 4 fixed to the road surface G. 2
b, and a horizontal rod 3 that connects the upper ends of these support legs 2am 2b.1 One end of the horizontal rod 3 is rotatable via a rotation shaft 5 at the upper end of one of the support legs 2a. The other end of the horizontal rod 3 is supported by the other support leg 2b.
A removable connecting portion 6 is formed between the upper end portion of the holder and the upper end portion of the holder.

The lower end of the bendable support leg 2b is connected to the bracket 4.
It is rotatably supported via a rotating shaft 8 by a bearing portion I protruding from the upper surface, and the axial direction of the rotating shaft 8 is approximately perpendicular to the axial direction of the rotating shaft 5. When one end of the horizontal rod 3 and the upper end of the support leg 2b are locked at the connecting portion 6, the locking of the connecting portion 6 changes the upright state of the support leg 2b and the horizontal rod 3. The horizontal state is maintained.

In this embodiment, as shown in FIG.
The cap 9 has a female threaded hole 10 in its center.
In addition, a connecting bolt 11 is provided at the upper end of the support leg 2b, and the male threaded portion 12 of the connecting bolt 11 is attached to the cap 9 provided at one end of the horizontal rod 3. It is screwed into the female threaded portion 10 to removably lock between one end of the horizontal rod 3 and the upper end of the support leg 2b.

Therefore, when installing the foldable vehicle intrusion prevention fence A of the first embodiment at the entrance/exit from a public road to a private road, for example, one support leg 2 is attached to the road surface G, taking into consideration the distance d that allows vehicles to pass.
A is erected, the other bendable support leg 2b is attached via the bracket 4 between the intervals d, and the support leg 2b and the horizontal rod 3 are locked by the connecting part 6, The bridge body 1 is installed horizontally at the entrance of a private road to prevent vehicle traffic under normal conditions, and at different times of the day or in an emergency, the connecting portion 6 can be unlocked as shown by the solid line in Fig. 3. The horizontal rod 3 is folded along one support leg 2a, and the other support leg 2b is folded into a lying state with respect to the road surface G, and a space d that allows a vehicle to pass is released to allow a vehicle to pass.

In addition, in the first embodiment, the bendable support leg 2b
The axial direction of the rotating shaft 8, which is supported between the lower end of the support leg 2a and the bracket 4, rotates between the upper end of the support leg 2a, which remains erected on the road surface G, and one end of the horizontal rod 3. Although the direction is approximately perpendicular to the axial direction of the rotary shaft 5 that is movably supported, the axial direction of the rotary shaft 8 and the axial direction of the rotary shaft 5 are made to be approximately parallel. In this case, the bendable support legs 2b are folded onto the road surface G within the virtual plane formed by the bridge body 1, so that the vehicle is folded into a lying position as shown in FIG. It is not possible to pass by straddling the folded support leg 2b, but the vehicle must pass by riding over the support leg 2b.

Moreover, FIG. 4 shows a modification of the connecting portion 6 in the first embodiment, in which the horizontal rod 3 is different from the case shown in FIG.
A fitting hole 13 is formed on the lower surface side of the end of the supporting leg 2b, and a fitting convex portion 14 is formed at the upper end of the support leg 2b, and the fitting convex portion 14 is fitted into the fitting hole 13 to be connected and locked. I did it like this,
A locking hole 15 is formed in each of the end of the horizontal rod 3 and the fitting convex portion 14, and a lock pin 16 is inserted into these locking holes 15 to prevent the connecting portion 6 from being unlatched unnecessarily. To release the locking of the connecting portion 6, first remove the lock pin 16, and lift the end of the horizontal rod 3 slightly to release the locking between the fitting hole 13 and the fitting protrusion 14. This allows the supporting legs 2b to be folded into a lying position, and then the horizontal rod 3 can be folded as well. The impact acting on the horizontal rod 3 is not transmitted to the support leg 2b via the connecting bolt 11, and the impact acting on the horizontal rod 3 is directly transmitted to the support leg 2b, thereby improving the strength of the bridge body 1.

In FIG. 4, reference numeral 17 is a cap that closes the end opening of the horizontal rod 3.

Furthermore, FIG. 5 shows a modified example of the horizontal rod 3 in the first embodiment, and this horizontal rod 3 includes a hollow outer rod 3a and an inner rod provided in the outer rod 3a so as to be freely retractable. 3b, and is formed to be extendable and retractable, and the distance between each support leg 2a and 2b can be adjusted by the length that the inner rod 3b can protrude and retract, and a vehicle intrusion prevention fence A is installed. Road surface G
It can accommodate various road widths, etc.

Note that a connecting portion 6 formed between the end of the horizontal rod 3 and the upper end of the bendable support leg 2b is formed between the tip of the inner rod 3b and the upper end of the support leg 2b. The connecting portion 6 in the case of FIG. 5 has a structure similar to that in FIG. 4, but is not particularly limited to this.
