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 shelf that is installed at the entrance 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 fences on the road surface at intervals that allow people and bicycles to pass through but not allowing vehicles to pass through, or fences that protrude from the ground. There are also known fences in which the fence is removably installed in an installation groove or hole provided 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 in an emergency, or a vertical hole with a depth equal to the height of the shelf on the road surface could be drilled to allow the fence to slide vertically. Installation work such as burying guide tubes for guiding becomes large-scale, or sand, pebbles, dirt, rainwater, etc. get into the guide tubes and accumulate, causing the guide tubes to swell or rust, causing fences to appear. There are various problems such as problems such as interfering with the movement of the fence, or people running away with the fence, or the fence becoming troublesome to move and being left on the roadside, so that it no longer functions as a fence. There are problems, and none of the conventional vehicle intrusion prevention methods are satisfactory.

In order to solve this problem, the main body of the island is constructed by a pair of support legs and a horizontal village, one end of the horizontal village is rotatably pivotally connected to one of the support legs, and the other end It has been proposed that the horizontal punch can be attached and detached from the other supporting leg, and the horizontal punch can be rotated when it is inconvenient (Japanese Utility Model Publication No. 10406/1983). One end of the horizontal pestle and the supporting leg are connected via a rotating shaft, and when a force is applied from above, such as by sitting on the horizontal pestle, a large load is applied to the rotating shaft, reducing the overall strength. This had the disadvantage that the In view of this point of view, the present invention stands on the road surface with yuzu bodies that are spaced apart from each other in the direction of the road so that vehicles can pass, and at the same time, depending on the time of day or in an emergency, the horizontal pestle of the shelf body is rotated to move it to its storage position. By making it possible to pass between the supporting legs, we have created a rotatable retractable vehicle intrusion prevention fence that can be used in emergencies, prevents people from carrying the fence and running away, and has excellent strength. This is what we provide.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

1 and 2, a rotating retractable vehicle intrusion prevention fence according to the present invention is shown, and this vehicle intrusion prevention paulownia A
The paulownia body 1 has a pair of support legs 2a erected on the road surface G.
, 2b, and a horizontal punch 3 supported by restoring both ends to the upper ends of these supporting legs 2a, 2b.

The support chests 2a and 2b are hollow pipe bodies as shown in FIG. 2, and are erected in the direction of the road at a distance d that allows vehicles to pass from each other, and have a receiving surface 8 formed at their upper ends.
This receiving surface 8 is for supporting both ends of the horizontal punch 3, and by bending the upper end of one leg 2a inward, the receiving surface 8 is used to support both ends of the horizontal punch 3. is formed by integrating flocks 14 at the upper end. The horizontal village 3 supported by the above-mentioned support legs 2a and 2b has one end bent downward, and a shaft foot 20 having a rotation shaft 4 is protruded from the tip thereof, so that the rotation A shaft 4 is fitted to the upper end of one leg 2a so as to be slidable and rotatable in the vertical direction, and is permanently connected to the leg 2a. On the other hand, at the other end of the horizontal punch 3, that is, on the lower surface side of the rotating end 6, there is formed a competing hole 9 that competes with the bulwark convex portion formed in the block 14 described above. When the terminal surface 3a on the 4 side is in contact with and stacked on the receiving surface 8 of the leg 2a, the iron-containing convex portion 10 of the leg 2b and the iron-containing hole 9 of the horizontal punch 3 are mutually connected. engage each other,
Horizontal rotation of the horizontal village 3 is prevented. In FIG. 2b, reference numeral 11 indicates a locking hole, and by inserting a lock pin 12, the locking between the nucleus insertion convex portion 10 and the side hole 9 is locked so that it will not be unnecessarily separated. 13 is a cap that closes the six rotating ends of the horizontal punch 3 formed of a hollow pipe.

Since the present invention is constructed as described above, when a vehicle is passing, the horizontal pestle 3 is lifted up as much as the ball foot part 20 on the rotary connecting part 5 side allows, and the horizontal pestle 3 is lifted into the Fujiai hole 9 on the connecting part 7 side. The carrying-in convex part 10 is removed from the horizontal village 3 around the rotating shaft 4.
By rotating the horizontal punch 3 substantially horizontally, the horizontal punch 3 can be moved to its storage position. Therefore, horizontal villages are installed at the entrances and exits of parks, entrances from public roads to private roads, entrances and exits of parking lots, etc., and the horizontal village is usually located at the location where it is used to prevent unauthorized entry of vehicles. In addition to being able to move the village into its retracted position and allowing vehicles to pass between each support leg, each support leg is connected to the road respectively, and the horizontal village can be moved to one support leg or two. Since it is divided and connected to each support leg, there is no chance of the shelf being carried away or left on the side of the road. There is no odor associated with vehicle intrusion prevention fences.

Furthermore, both ends of the horizontal punch are supported by the upper end of the branch chest, so even if a vertical force is applied to the horizontal pestle, this force can be reliably transmitted to the pair of supporting legs. Since it is possible to prevent a large load from being applied to the rotating shaft, etc., the overall strength can be improved.

Claims (1)

[Claims] 1 Both ends of a horizontal rod are placed on receiving surfaces formed at the upper ends of a pair of support legs erected on the road surface, and one end of the horizontal rod has a vertical sliding plate on the one leg. A rotary shaft to which the legs are fitted so as to be movable and rotatable is provided so as to protrude downward, and a fitting hole is formed at the other end to fit into a fitting convex portion which is provided on the receiving surface of the other leg. By moving this horizontal rod upward, the fitting between the fitting convex portion of the other leg and the fitting hole of the horizontal rod is released, and rotation of the horizontal rod about the rotation axis is allowed.
