Description

Trailer equipped with a indicating apparatus of sign-car for the direction}

The present invention relates to a trailer that moves to a required place when a vehicle is needed in a temporary traffic control or construction section on a highway, and displays a point light, more specifically, a towing vehicle (e.g., a truck) in the form of a trailer with a small towing type. It relates to a trailer equipped with a sign car direction display device to prevent the phenomenon that the direction display device (eg, signboard, electronic signboard) is shaken when driving by connecting a car.

In general, a trailer-type sign car connected to a towing vehicle induces a lane change by displaying a signal to a driver of a driving vehicle to change the lane on the road.

The sign car is composed of a direction display device formed of a display panel for indicating a direction with a plurality of lights and a trailer towed by a towing vehicle mounted thereon to move to a construction site to indicate the direction of the changed lane.

However, a sign car that is connected to a conventional towing vehicle and moves, when the signboard for direction display having a large area unfolded in the driving direction unfolds toward the front in order to increase visibility, is unaffected when it reaches the work site and stops. While driving, it was difficult to quickly start due to the air resistance hitting the unfolded signboard surface, as well as a problem that the signboard and the fixed shaft supporting the signboard were significantly damaged.

Thus, in the past, a signboard having a folding structure has been installed in a driving vehicle, which is limited to use only when stopping, and is laid down and fixed when driving to prevent equipment damage due to air resistance.

However, in the above-described method, since the signboard is folded while driving, there is a problem in that an emergency situation can not be communicated to a vehicle approaching the scene as well as at the accident site.
