Description

PORTABLE EMERGENCY INDICATOR FOR SAFETY

The present invention relates to a portable safety display device for promptly and accurately informing a driver of a forward dangerous situation to a driver of another vehicle driving from the rear during road construction or vehicle accidents and breakdowns.

As is well known, emergency parking on the road is unavoidable when various conditions on the road that can cause a traffic accident while driving, for example, damage to the road surface or an accident or breakdown of a vehicle occur, are frequent. In this case, in order to prevent an unexpected collision accident, it is necessary to display it appropriately so that the driver of the vehicle driving from the rear can recognize the emergency situation ahead. As a general method for this, a triangular-shaped emergency sign (aka, "tripod") is installed at the rear of an emergency parking vehicle.

In addition, even when there is a problem in driving due to the passage of vehicles for road maintenance and construction, emergency sign boards are installed to induce safe driving. Even in this case, it is common to use emergency sign boards provided in the vehicle.

However, since the emergency display board has a small size and very low visibility due to the characteristic of having to be stored in the trunk of a vehicle, it was not possible to easily recognize a situation in which a vehicle traveling in the rear occurred in the front. In addition, since the emergency sign must be installed at a point that secures a sufficient distance from the accident point, the risk of an accident caused by nearby vehicles is also quite high.

As a result, secondary accidents such as a vehicle following a vehicle parked on the road collided again due to breakdown, or the driver of an accident vehicle installing an emergency sign was struck by a vehicle following frequently. Moreover, the death rate due to such secondary accidents is known to be very serious, far exceeding that of general accidents.
