DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 and 4, the fence device 1 is provided at a predetermined interval in the direction in which the gate post a crosses the entry / exit path b on both sides of the road. Also this fence device 1
Is a vertical hole 2 formed in the entry / exit path b, a fence member 3 which is housed in these vertical holes 2 and is arranged to stand up to a predetermined height above the ground, and these fence members 3
It is mainly composed of a fence moving means 12 for moving it further in and out.

In the vertical hole 2, the ground is excavated from the entry / exit path b by a boring method or the like to vertically form a foundation hole 4 having a predetermined depth, and concrete is poured into the bottom of the foundation hole 4, and then the foundation is formed. The casing pipe 5 is loosely inserted with one end of the opening 7 facing the ground in the hole 4, and concrete is poured into the gap formed between the outer surface of the casing pipe 5 and the inner wall surface of the foundation hole 4. It is formed. The base hole 4 has an outer diameter that allows the casing pipe 5 to be loosely inserted therein. Further, the casing pipe 5 has a length substantially shorter than the depth of the base hole 4, a screw groove 14 is formed on the inner side surface portion of the uppermost portion 13, and a ring-shaped seal having a screw groove 14 corresponding thereto. While packing 15 is screwed,
A cable insertion hole 17 through which the operation cable 16 from the outside is inserted is formed in the upper side surface portion.

Further, the fence member 3 is formed of a metal cylindrical body 9 which is shorter than the casing pipe 5 and has an outer diameter equal to the inner diameter of the seal packing 15.
5 has an umbrella-shaped roof portion 26 having a larger cross-sectional area than the opening portion 7 of the vertical hole 2 while being inserted into the inner portion 5 in a liquid-tight manner and axially movable. Further, the lower side of the roof portion 26 of the side surface portion 27 of the cylindrical body 9 is transparently formed to form a light projecting window 18, and a light emitting body 19 is provided inside the light projecting window 18 to cause the fence member 3 to emit light automatically. .

Further, the fence moving means 12 is a geared motor 20 fixed inside the cylindrical body 9 with a rotary shaft 21 facing downward.
And a screw shaft 22 that is connected to the rotary shaft 21 of the geared motor 20 and extends downward, and that has a screw groove 24 for moving, and is fixed to concrete at the inner bottom portion of the vertical hole 2 and stands up. It is mainly composed of a support member 23 to be screwed. This support member 2
3 is formed in a tubular shape coaxial with the casing pipe 5, has an outer diameter equal to the inner diameter of the tubular body 9, and is always inserted into the tubular body 9, and the tubular body 9 moves up and down. Give guidance to 9. In particular, since the support member 23 is always inserted into the tubular body 9, and the tubular body 9 is supported by the support member 23 from the inside thereof and by the seal packing 15 from the outside thereof, the tubular body 9 is also laterally supported. It can be firmly supported and can have high collision resistance. A screw receiving member 25 having a moving screw groove 24 is provided on the upper portion of the support member 23 to screw the screw shaft 22.

A fence device operation panel (not shown) is provided in the external control room or the gate pole a, and an operation cable 16 extending from the fence device operation panel is connected to the light emitter 19 and the geared motor 20. The light emission of the light emitter 19 and the rotation control of the geared motor 20 are externally performed.

Next, the operation of the embodiment will be described.

First, when the fence member 3 is lifted to stand up on the road, the geared motor 20 is operated from the outside to the rising side, and the screw shaft is moved by the moving screw groove 24 screwed into the screw receiving member 25. 22 rises, the fence member 3 rises, and stands up on the road. In this way, the fence member 3 rises and stands up on the road, thereby blocking the road and achieving its original function. Further, at this time, if the outside becomes dark, the fence member 3 emits light automatically by operating the fence device operation panel to automatically or manually activate the light emitter 19. As a result, the fence member 3 can be easily confirmed even in the dark at night and the like, and the collision of the vehicle or the like can be prevented in advance.

Similarly, the geared motor 20 is externally applied.
As shown in FIG. 2, the fence member 3
Is lowered and is stored in the vertical hole 2. At this time, the roof portion 26 of the fence member 3 is exposed on the road, but since the roof portion 26 is formed in an umbrella shape, even if the vehicle or the like passes over it, the shock given to the vehicle or the like is small. The vehicle can pass through smoothly and the shock given to the fence device 1 itself can be alleviated. Of course, the same effect can be obtained by forming the roof portion 26 into, for example, a dome shape. In addition, if the roof portion 26 is also transparently formed, and if the light-emitting bodies 19 are provided in a plurality or in various colors, the roof portion 9 and the light projecting window 18 can be changed in various manners when the fence member 3 is stored or stored. It can also be used as a display or a signal lamp by emitting light in different colors. Further, in the present embodiment, the raising and lowering of the fence member 3 is performed electrically using the geared motor 20, but it is of course possible to perform the raising and lowering using the hydraulic cylinder unit or the air cylinder unit.

As described above, if the fence device having the above-described configuration is provided in the entry / exit path, the fence devices are automatically and simultaneously erected by remote control, thereby facilitating entry and exit of vehicles and the like. It can be cut off in a short time. In addition, since it cannot be removed, safety is improved without carelessly allowing the vehicle to pass, and the original purpose of the fence device can be sufficiently achieved. Further, when the road is released, similarly, the fence devices can be automatically stored all at once by remote control so that this can be achieved easily and in a short time. By storing the fence devices, the problem of conventional storage can be solved. If the collision resistance of this fence device is strengthened, a runaway vehicle or the like can be stopped, and by providing it at a railroad crossing, a collision accident with a railroad vehicle can be prevented in advance. Further, since a plurality of fence devices are independently provided in the entrance and exit paths, there is also an advantage that installation work and inspection and repair can be independently and easily performed one by one.

[0026]

The present invention exhibits the following excellent effects.

(1) It is possible to easily open and close the fence member by remote control to open and close the fence device, and to improve the workability thereof.

(2) The fence member can be stored in the ground right below when the vehicle is opened, so that no obstacle is given to the passage of the vehicle.

(3) The fence device can be made self-luminous so that it can be confirmed even at night.

(4) The fence member used in the fence device can be increased in necessary strength, and if this device is adopted as a railroad crossing, runaway vehicles etc. can be prevented from entering the railroad line, so railroad disasters can be eliminated. .
