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 foldable vehicle intrusion prevention shelf installed at the entrance and exit of a parking lot, which normally prevents vehicles from entering without permission and also allows vehicles to pass through depending on the time of day or in an emergency.

Conventional vehicle intrusion prevention fences of this type, such as those installed at park entrances and exits, have shelves that are shaped like an inverted U on the sides, allowing people, bicycles, etc. to pass through, but vehicles cannot pass through. They are placed on the road surface at intervals that would be impossible to park, or, for example, they are placed at the entrances and exits of parking lots, where they are buried underground during the Air Force, and when they are full, they are pulled out of the ground and protruded from the road surface. There are also known devices in which the shelf is capable of being folded down to the road surface near its lower end, so that when a vehicle passes, the fence is folded down to allow the vehicle to pass.

However, if fences are erected and fixed on the road surface at intervals that prevent vehicles from passing, even if an emergency such as a fire occurs and fire engines need to pass, fire engines cannot pass through. In addition, if it is necessary to force the vehicle to pass through the vehicle, the vehicle intrusion prevention shelf must be dismantled, which poses the problem of not being able to respond to emergencies, and also causing the shelf to disappear or disappear from the ground. In such a case, a vertical hole with a depth equal to the height of the fence is bored in the road surface, or a vertical hole with a length approximately equal to the height of the fence is made to guide the vertical sliding of the fence. The guide tube had to be buried, making the construction work for installing the vehicle intrusion prevention shelf extremely large-scale.
Unless the installation is done in advance during road construction, attempting to install it later will be extremely troublesome, and
If sand, stones, dirt, etc. get into the guide tube that is buried underground, it will be almost impossible to remove it because the bottom of the guide tube is deep underground. There is a problem in that rainwater gets in and rusts, which eventually interferes with the fence's ability to move in and out.Furthermore, if the shelf is made to be able to fall down on the road near the bottom end, it may cause rust when vehicles pass by. There are problems in that vehicles often run onto the vehicle intrusion prevention shelf, and the fence is severely damaged, and conventional vehicle intrusion prevention shelves are not satisfactory in any of these situations.

In view of this point of view, the present invention has been developed to provide a vehicle that cannot be removed from the road surface and is normally erected to prevent vehicle intrusion.
To provide a vehicle intrusion prevention shelf whose column can be folded from its base to the road surface so that vehicles can pass through it without running over it depending on the time of day or in an emergency.

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 shelf A according to the present invention is shown.

This foldable vehicle intrusion prevention shelf A includes a support member 4a and a support base 4b that are fixed to the road surface G, and a willow body 2 that is approximately inverted U-shaped.
and cylindrical holders 3a, 3b that cover the connecting parts 6a, 6b between the supporting member 4a and the support base 4b and the lower ends of the legs 5a, 6b of the shelf main body 2, and hold the shelf main body 2 in an upright state. It is configured. In this embodiment, the support member 4a and the support stand 4b are integrally formed on the substrate 1, and the support member 4a and the support stand 4b are integrally formed on the substrate 1.
It is mounted on the road surface G by fixing the flange 7 to the road surface G using anchor bolts or the like.

Furthermore, the fence main body 2 formed in a substantially inverted U shape has a pair of legs 5.
a. 5b, and one leg 5a has a leg 5 on its upper part.
A rotating part 13 having a rotating shaft 12 is formed on the central axis of the leg part 5a, and the lower end of the lower part of the one leg part 5a below the rotating connecting part 13 (hereinafter referred to herein as "this" unless bookkeeping is used). The portion (simply referred to as the "lower end portion of the leg portion 5a" or "lower end portion of the leg portion 5a") is rotatably supported via a rotating shaft 8 which uses the support member 4a as a bearing, and thereby the connecting portion 6a is formed. This connecting part 6a is covered with a cylindrical holding odor 3a that can move vertically along the legs 5a, and when this holding odor 3a covers the connecting part 6a, the legs of the shelf body 2 When 5a tries to rotate around the spinning shaft 8, the leg portion 5a is placed on the upper end of the holding member 3a, and the lower end of the holder 3a is placed on the supporting member 4a.
Rotation of the leg portions 5a is restricted by contacting the lower ends thereof, respectively. On the other hand, the lower end portion of the other leg portion 5b, which is configured to rotate around one leg portion 5a with the rotating shaft 8 of the rotary connection portion 13 as the rotation center, is placed on the support base 4b as shown in FIG. The connecting portion 6b between the support base 4b and the lower end of the leg portion 5b is covered with the retaining odor 3b.

This holding shell 3b is for preventing the leg portion 5b from rotating around the rotating shaft 12 of the rotary connection portion 13, and is capable of vertically sliding in a cylindrical shape like the holding shell 3a described above. is formed. In order to fold the foldable vehicle intrusion prevention shelf A configured as described above, as shown in FIG. The side is rotated 900 times around the center axis of the leg part 5a by the rotary connecting part 13, and further, the holder 3a is moved upward to free the connecting part 6a, and the axis of the rotating ball 8 of this connecting part 6a is rotated. By rotating the legs 5a, the shelf body 2 can be folded as shown in FIG.

Therefore, according to the foldable vehicle intrusion prevention shelf A of the present invention,
Since the shelf main body 2 is folded by a combination of horizontal rotation around the central axis of one leg 5a and vertical rotation around the rotation axis 8 of the connection part 6a, the connection part 6a is folded on the road surface G. By appropriately changing the position and the axis 0 direction of the rotation axis 8 of this connecting part 6a, the fence body 2 can be folded as close to the edge of the road surface G as possible to secure a space for vehicles to pass. It is possible to prevent a vehicle from running onto the vehicle as much as possible. 5 and 6 show a modification of the connecting portion 6a between the lower end of one leg 5a and the support member 4a. The lower end of the leg 5a and the support member 4a are connected by a hinge 9. The cylindrical holder 3a that is connected and covers the above-mentioned fastening part 6a to maintain the upright state of the shelf main body 2 has a female thread (not shown) carved on the inner surface thereof, and the lower end of the leg part 5a. It is screwed onto a male screw 10 cut on the outer periphery and is slidable in the vertical direction with respect to the support section 4a.

In this embodiment, reference numeral 11 is a gasket made of rubber or the like, and the retaining odor 3a is passed through the external thread 10 of the leg portion 5a.
When screwed in, the upper end of the holder 3a comes into close contact with the packing 11, so that the hinge 9 is protected from rainwater etc. when the vehicle intrusion prevention shelf A is in the upright state shown in FIG. still,
Although FIGS. 1 to 6 show the case where the support member 4a and the support stand 4b are integrally formed on the substrate 1, the present invention is not limited to this, and as shown in FIG. It may be fixed separately on the road surface G.

Furthermore, as a means for regulating the vertical sliding of each holder 3a, 3b, as shown in FIGS. 8 and 9, the shelf main body 2
A stopper 15 is provided at the lower end of each leg 5a, 5b,
Each retained odor 3a, 3b has the above-mentioned stopper 1 on its inner surface.
5 is formed, and the positions of the stopper 15 and the groove 16 are shifted when the shelf main body 2 is in an upright state or in a collapsed state, and the lower ends of the legs 5a, 5b and the supporting member It prevents the holders 3a, 3b provided on the connecting parts 6a, 6b between the shelf body 4a and the support base 4b from moving upwards and releasing the holding on the connecting parts 6a, 6b. When it is necessary to move each holding odor 3a, 3b up and down in order to fold or stand up the odor 2, rotate each odor 3a, 3b to align the stopper 15 and groove 16. The retained odors 3a and 3b may be moved upwards smoothly. As described above, the foldable vehicle intrusion prevention shelf A of the present invention can be installed at the entrance to a park, the entrance from a public road to a private road, the entrance to a parking lot, etc., and can usually prevent unauthorized vehicle intrusion. In case of emergency, etc., the shelf body should be folded as close to the edge of the road surface G as possible, as shown by chain lines in Figures 10 and 11, so that vehicles can pass without riding over the shelf body. In addition, since the shelf body is fixed to the road surface via a support member, the shelf body cannot be carried away or thrown out on the roadside, and it is easy to fold and stand up. In addition, the structure is simple, and even if it gets covered with sand, etc., there is almost no problem in operating the shelf itself.
