Description

[Detailed Description of the Invention] The present invention particularly relates to the improvement of a traffic sign that is mounted on the ceiling of a tunnel and used in the event of an emergency.

Traffic signs are indispensable and important for ensuring smooth traffic flow, providing services to passersby, and ensuring safety.

In particular, in tunnels, etc., which have special road environment conditions, the space is narrow and evacuation is not easy.
Not only do passersby feel a great psychological pressure and anxiety, but visibility is poor and vehicle exhaust gas accumulates, shortening the visibility distance, creating an environment that is both psychologically and physically unfavorable. There is a risk that even the slightest accident or disaster could cause confusion and lead to a major accident.

Therefore, in the event of an emergency, we must promptly notify passersby, provide appropriate instructions, stop traffic, or
Traffic signs play an important role in evacuation.

Traffic signs for this purpose need to be clearly displayed to confused passersby, and must be large, bright, and clear so that they can be easily seen by passersby.

However, in tunnels, traffic space is limited due to economic reasons, and it is difficult to always reserve space for traffic signs. There was a risk that it would become a traffic obstruction.

For example, construction limits regarding the height of road tunnels are set, and the height of the tunnel must be at least 4.
A minimum distance of 5m is required, and normally this should not be compromised.

In view of the current situation, the present invention has been developed by rotating the main body of a sign that indicates the occurrence of an emergency situation and instructions thereon to a sign support that is fixed in the ceiling of a tunnel or the like or in a recess provided in the ceiling. The main body of the sign is always attached to the ceiling so that it does not obstruct or obstruct traffic, or it is placed on the ceiling or in a recess so that it can be stored in a recess provided in the ceiling. By installing an electromagnet or magnetic material that loses its attraction power when the general lighting goes out, and by installing a magnetic material or an electromagnet that loses its attraction power when the general lighting goes out in the sign body, it is possible to prevent the occurrence of an emergency. The main body of the sign that displays instructions, etc. should always be attached to the ceiling surface or stored in a recess to ensure a safe traffic space. The present invention is intended to make it possible to provide traffic signs that can be fixed, rotated by gravity, and hung from the ceiling surface or its recesses to clearly indicate to passersby the occurrence of an emergency situation and its response. The invention will be explained in detail by means of illustrated embodiments.

In Figures 1 and 2, 1 is a sign body indicating the occurrence of an emergency situation and instructions therefor, and the sign body 1 is connected to a sign support 5 fixed to a ceiling surface 4 of a road tunnel or the like. It is rotatably supported via a fixture 2, and is normally pulled up by a wire, rope 7, etc., and stored in a recess 8 provided in the ceiling surface 4, so that it does not interfere with traffic. It is done like this.

At this time, the sign body 1 has an electromagnet 9 in the magnetic part.
It is maintained in a retracted state by suction, and the wire,
The rope 7 and the like are in a relaxed state.

In the event of an emergency such as an accident or disaster, the sign body 1 is moved from the ceiling 4 to the passerby at the same time as a general lighting power outage, which tends to occur at the same time, or by artificially losing the attraction force of the electromagnet 9. It hangs and protrudes in a position where it is easy to see, and it has a simple and excellent effect that can quickly indicate evacuation exits etc. to passersby.

Note that it is desirable to attach an elastic material to the vicinity of the edge of the surface of the sign body 1 that is close to the ceiling surface 4.

In addition, in road tunnels, the sign body 1 is stored at a position higher than 4.5 m from the road surface in accordance with the construction limit, but in an emergency, the top priority must be given to clearly informing passersby of information. Therefore, it is also possible to arrange the sign body 1 so that it hangs down slightly within the building limits.

Incidentally, the sign body 1 may be a plate-shaped sign generally used as a traffic sign, but it is desirable that it be large, bright, and clear.

In particular, traffic signs that use paint that utilizes the light-reflecting properties of microscopic glass particles or that use Sheetra strongly reflect light from car lights, etc., even if general lighting is out of service, providing clear information to passersby. can be notified.

Furthermore, the sign body 1 is box-shaped with electric lighting such as electric lights and neon lights inside, and a storage battery dedicated to this electric lighting is used, which is switched on at the same time as the sign body 1 is rotated. In the event of a lighting power outage, only the sign body 1 is lit, and information can be clearly communicated to passersby.

Furthermore, it is clear that the traffic sign according to the present invention can achieve the same function and effect even when installed not only in road tunnels but also in underground passages, passages inside structures, etc., and is based on the same technical idea. It is.

As is clear from the above explanation, in the traffic sign according to the present invention, the sign body is rotatably supported on a sign support fixed in the ceiling of a tunnel or the like or in a recess provided in the ceiling. An electromagnet or magnetic material that loses its attraction power when the general lighting goes out is installed on the ceiling surface or its recess, while a magnetic material or an electromagnet that loses its attraction power when the general lighting goes out is installed in the main body of the sign. Therefore, at all times, a safe traffic space is ensured by placing it along the ceiling of a tunnel, etc., or storing it in a recess installed in the ceiling, and in the event of an emergency such as an accident or disaster, The attraction power of the electromagnet is lost due to the power outage of general lighting that tends to occur or artificially, and the main body of the sign that indicates the occurrence of an emergency and instructions therefor is rotated and hung so that it protrudes from the ceiling surface and is visible to passersby. The occurrence of an emergency and instructions for it are clearly and promptly displayed to prevent confusion and enable smooth evacuation, and the system is well-maintained, requires little maintenance, and operates reliably. This makes it possible to further enhance the usefulness of traffic signs.

[Brief explanation of drawings]

The drawings show an embodiment of the traffic sign according to the present invention, and FIG. 1 is a side view of the traffic sign when in use, together with a part of a road tunnel that traverses it. It is a front view shown similarly to the figure. Note that the same reference numerals in the figures indicate the same or equivalent components. 1: sign body, 2: connector, 4: ceiling surface, 5: sign support, 7: wire rope, etc., 8: recess.

Claims (1)

[Scope of utility model registration request] The main body of the sign, which indicates the occurrence of an emergency situation and instructions therefor, is rotatably supported on a sign support fixed to the ceiling surface of a tunnel, etc., or within a recess provided in the ceiling surface, and the sign body is rotatably supported. The main unit should always be placed on the ceiling or stored in a recess in the ceiling (place an electromagnet or magnetic material on the ceiling or in the recess that loses its attraction power when the general lighting goes out). On the other hand, a traffic sign is characterized by having a magnetic material or an electromagnet that loses its attractive force when the general lighting goes out.
