Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opposite lane blinding device for shielding an opposite lane from a driver when an accident occurs on an ordinary road having a relatively wide width.

[0002]

2. Description of the Related Art If there is an accident or construction in one lane of a wide road such as an arterial road, the driver of the vehicle traveling in the opposite lane will see the traveling speed. I often see this while dropping. As a result, cars often get jammed in the opposite lane with no obstacles.

An object of the present invention is to provide an opposite lane concealing device which can be easily and quickly installed on a median strip or the like, can shield the opposite lane in which an accident or construction has occurred, and prevent a decrease in traffic flow. It is to be.

[0004]

SUMMARY OF THE INVENTION An opposite lane concealing device of the present invention is a pole that is removably erected on a pole supporting member provided on a road and is wound around the inside or the outer periphery of the pole so that it can be drawn out. And a shielding screen. The pole support member is provided in advance at a constant pitch on the median strip or the like.

According to another aspect of the present invention, there is provided an opposite lane blinding device, wherein the pole is a pipe shape capable of accommodating the shielding screen in a rolled-up state, and a slit for feeding the shielding screen
And a winding device for the shielding screen is provided on the pipe pole. Further, an engaging tool is provided on the feeding end of the shielding screen, and an engaged tool that engages with the engaging tool is provided on the pole.

[0006]

In the case where an accident occurs in one lane, a required number of the opposite lane concealing devices are transported to the site and the poles are set up on the pole support members provided on the road at a predetermined pitch in advance. Also, unfold the shielding screen and connect its end to the adjacent pole. This forms a blind fence in which the shielding screen is long and continuous. Therefore, an accident or the like that occurs in the opposite lane can be shielded from the driver in the lane that does not interfere with the traffic, thereby preventing traffic congestion.

According to the second aspect of the present invention, since the pole has a pipe shape, the shielding screen can be housed in the pole for transportation and storage. In addition, the shield screen can be easily pulled out from the pole when in use. The spread shielding screen can be easily stretched in a continuous state by engaging the engaging tool at its end with the engaged tool of the adjacent pole.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of an opposite lane blindfold device 1 of this embodiment. The pipe-shaped pole 2 is provided with a vertically long slit 3 for feeding the shielding screen 5, and a pair of upper and lower spring spring devices 4 and 4 which are a winding device of the shielding screen 5 are built in the pole 2. The mainspring device 4 is provided with a lock function 22 for stopping the winding at an arbitrary length of extension. Lock mechanism 22
Is provided with a check claw 24 which is biased by a spring 23 to push the shielding screen 5 and a push release button 25.

A bar-shaped edge member 6 is provided at the feeding end of the shielding screen 5, and a pair of upper and lower hooks 7, 7 are provided on the edge member 6. On the other hand, on the outer periphery of the pole 2, a pair of upper and lower engaged rings 9, 9 that engage with the hooks 7, 7 of the screen 5 are provided, and a fin-shaped joint plate 8 for hiding the joint of the screen 5 is provided. It is projected along the direction. The joint plate 8 is made of synthetic rubber or resin material. The vertical dimension of the shielding screen 5 is set to such a level that the opposite lane cannot be seen from the eyes of the driver 21 of the traveling vehicle 20 (FIG. 3) in the installed state. The horizontal dimension of the shielding screen 5 is, for example, about 2 m.

As shown in the horizontal sectional view of FIG. 2, the mainspring spring device 4 has locking pins 10 projecting from the partition plate 2a and the top plate (not shown) in the pole 2, and the locking pins 10. A mainspring spring 11 whose inner peripheral end is locked to the pin 10 and a cylindrical body 12 in which the mainspring spring 11 is loaded.
An opening 12a is formed in the peripheral wall of the cylindrical body 12 so as to face the outer peripheral end of the mainspring 11, and is connected to the inner peripheral end of the shielding screen 5. The cylindrical body 12 rotates as the shielding screen 5 is unwound from the pole 2, and the mainspring spring 11 loaded in the cylindrical body 12 is tightened by this rotation, and the winding force of the shielding screen 5 is applied to the mainspring spring 11. It is stored.

A method of using the opposite lane blindfold device 1 will be described below.
This will be described with reference to FIG. In the median of the road,
Each guardrail prop 15 with the guardrail 13 installed
In advance, a pole support member 14 for inserting the pole 2 is provided in advance. The pole support member 14 is composed of a bottomed pipe or the like. When a retaining wall is provided instead of the guardrail 13, the pole support members 14 are provided on the retaining wall at a constant pitch. The pole support member 14 may be a hole provided in the retaining wall. Further, the pole support member 14 may be provided on the curb 16.

When a traffic accident occurs in one of the lanes on the road, for example, the opposite lane blindfolding device 1 is transported to the site as much as necessary for blindfolding the accident section, and the poles of each opposite lane blindfolding device 1 are carried. 2 is inserted into each pole support member 14 to stand up.

Next, the shield screen 5 is extended from the pole 2 against the restoring force of the spring device 4, and the hooks 7, 7 at the extended end are hooked on the engaged rings 9, 9 of the adjacent pole 2. As a result, the shielding screen 5 is stretched in a strip shape over the accident section. Therefore, the lane on the accident side can be shielded from the driver 21 of the traveling vehicle 20 on the opposite lane, and the traffic congestion caused by the driver 21 slowing down the vehicle while watching the accident can be prevented.

Thus, the pole 2 is attached to the pole support member 1
By simply inserting the cover 4 and opening the shielding screen 5, the blind spot at the accident site can be easily covered, and a wide range of cover can be covered in a short time. Also, the pole 2 and the shielding screen 5
The gap formed with the end portion of is covered with the joint plate 8 on the side of the pole 2 so that reliable blinding can be performed. Moreover, it suffices to provide the pole support member 14 on the road, and the structure is simple. When the opposite lane blindfolding device 1 is removed, the hook 7 is removed and the lock mechanism 22 of the spring device 4 is unlocked, so that the shield screen 5 is wound into the pole by the spring force of the spring device 4. Therefore, the removal work can be performed easily and quickly.

Although the spring device 4 is provided as the winding device in the above embodiment, the winding device may be wound by the rotation of the handle.

[0016]

In the opposite lane blinding device of the present invention, the pole is provided with a shielding screen so that the pole can be extended, and the pole is inserted into a pole support member previously installed in a median strip of a road or the like to stand upright. It is possible to blindly and easily blind the accident site and the like, and it is possible to prevent traffic congestion caused by the driver slowing down while seeing an accident or the like in the opposite lane.

In the case of the structure of claim 2, the shield screen can be housed in the pole, which is convenient for transportation and storage, and at the time of use, the shield screen is pulled out from the pole so that the engaging member at the end portion is adjacent to the pole. By hooking, it can be easily stretched in a continuous state. Moreover, at the time of removal, the shielding screen can be easily wound into the pole with the winding device. Therefore, it can be installed and removed more quickly.
