In the event of an accident on an expressway or general road, road construction, etc., various regulatory equipment will be installed for traffic regulation. Arrow plates and color cones (registered trademarks) (registered trademarks) are often used as regulatory equipment, but the work of removing multiple of them from the patrol vehicle and bringing them to the site is a heavy burden on the workers and is installed. The work and removal work also took time. In addition, since it is difficult to evacuate the traveling vehicle during the work, the longer the work, the higher the degree of danger.

Normally, the movement work at the time of installation and removal of regulatory equipment is performed using a trolley, but in the case of a general trolley, the loading platform is simply a flat plate, and the arrow plate and color cone (registered trademark) are placed in a stable state. It is not a specification that can be placed. In addition, since the dolly is no longer needed after the work of moving the regulating equipment, it takes time and effort to clean it up.

In view of this situation, a hand truck with a display function capable of displaying characters, figures, and the like on the back surface of the loading platform has been proposed (Japanese Patent Laid-Open No. 2019-147448). The hand truck according to this proposal is carried to a traffic regulation site and laid down as it is to expose the display on the back surface of the loading platform so that the display can be visually recognized from the traveling vehicle.

It is a figure which shows the transport state of the arrow board and the color cone (registered trademark) by the arrow display device for lane regulation which concerns on this invention. It is a figure which shows the arrangement example of the arrow display device for lane regulation, the arrow board and the color cone (registered trademark) which concerns on this invention.

The embodiment for carrying out the present invention will be described in detail with reference to the accompanying drawings. The lane regulation arrow display device according to the present invention is installed on the rectangular carriage frame 1, the U-shaped handle frame 2 attached to one short side 1a of the carriage frame 1, and the back surface of the carriage frame 1. It is composed of an arrow plate 3 representing a plurality of arrows 4 with a high-intensity reflective material, and is characterized in that a weight is added to the upper side 5 of the handle frame 2. The arrow plate 3 is usually a lightweight aluminum plate.

In order to add weight to the upper side 5 of the handle frame 2, for example, a metal tube 10 having a diameter slightly smaller than that of the upper side 5 may be fitted in the upper side 5 formed of the pipe material (see FIG. 7). .. Alternatively, weights may be attached to both ends of the upper side 5. In the present invention, adding weight to the upper side 5 of the handle frame 2 is a measure against wind when a large vehicle passes through, as will be described later.

Casters 7 are attached to the four corners of the arrow plate 3. The caster 7 is preferably provided with a stopper. Further, the handle frame 2 is made foldable on the carriage frame 1 by the same method as in a general carriage (using the lock plate 9).

Articles can be placed so as to straddle the long sides 1b and 1b of the carriage frame 1. In the case of the regulatory arrow plate device according to the present invention, the objects to be mounted are mainly the self-supporting arrow plate 11 and the color cone (registered trademark) 12. Therefore, the distance between the long sides 1b and 1b of the bogie frame 1 corresponds to the size of the base of the color cone (registered trademark) 12. Further, in order to keep the arrow plate 11 and the color cone (registered trademark) 12 on the long sides 1b and 1b in a stable state, the sidebars 6 and 6 are parallel to the outside of the long sides 1b and 1b via the connecting piece 8. Is arranged. Then, preferably, a rubber non-slip material is adhered to the sidebar 6.

The lane regulation arrow display device according to the present invention is mounted on each patrol vehicle together with a plurality of arrow plates 11 and a color cone (registered trademark) 12, and is brought to the regulation site. Since the carriage frame 1 and the handle frame 2 in this device are merely a frame of pipe material, and the arrow plate 3 is a relatively lightweight aluminum plate, the total weight is at a level that does not burden the operator. It is easy to carry in and out of the patrol car.

After arriving at the regulation site, the operator lowers the device with the handle frame 2 folded, raises the handle frame 2, and then attaches a plurality of arrow plates 11 to the latter half of the trolley frame 1 (handle frame 2 side). The stacking color cones (registered trademarks) 12 are placed in the first half of the handlebars 6 and 6 in an upright position. At that time, since both sides of the color cone (registered trademark) 12 are held down by the sidebars 9 and 10, the color cone (registered trademark) 12 can be moved in a stable state without laterally shifting and falling. Further, especially when the sidebar 6 is covered with a rubber anti-slip material, the arrow plate 11 is prevented from skidding.

After moving to the installation location, the operator lays down the device on which the arrow plate 11 and the color cone (registered trademark) 12 are lowered so that the arrow plate 3 on the back surface of the trolley frame 1 faces the traveling direction of the vehicle. The carriage frame 1 is supported by the handle frame 2 and does not fall over. As shown in FIG. 9, the device is arranged in the foremost position for use as a warning plate, and the arrow plate 11 and the color cone (registered trademark) 12 are appropriately arranged in the rear position thereof. In addition, smoke bombs are appropriately arranged.

Although this device is used by lying down as described above, it is lighter than a general trolley. Therefore, there is a risk that the vehicle will shift due to wind pressure as it passes by a large vehicle or the like. However, in the case of this device, since the weight is added to the upper side 5 of the handle frame 2 and it becomes a large resistance to the wind pressure, it is avoided to shift due to the wind pressure.

The lane regulation arrow display device according to the present invention is as described above, has a simple structure and is relatively lightweight, and has an arrow plate 11 and a color cone (registered trademark) 12 which are regulation devices. Since it is suitable for movement, it is possible to reduce the burden on the operator when installing and removing the regulatory equipment in the lane regulation area, and it is possible to perform those operations quickly and safely, and it is large when used. Its industrial utility is great because it is prevented from shifting even when it receives wind pressure due to the passage of a vehicle, and thus has the effect of maintaining an appropriate traffic regulation function.
