Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention uses the roof of a passenger car to erect advertising boards, display boards, etc. and rotates them. The present invention relates to an in-vehicle public information display device suitable for informing passersby, passing vehicles, etc. of information under special environments.

(Prior art) Like a funeral held in a place facing a road with relatively heavy traffic,
Under special circumstances, it is necessary to safely guide mourners and vehicles passing around the venue.

Conventionally, when holding funerals at such locations, the number of funeral management personnel has been increased to ensure safety by regulating traffic and directing traffic.

On the other hand, in general traffic regulation, it is known that a predetermined vehicle is loaded with a display board that displays information necessary for driving, such as a display board that indicates road construction, traffic accidents, etc. For example, a vehicle-mounted sign device was developed in 1118/1985 that set the sign body from an upright state to a stowed state by driving a motor.
It is described in Publication No. 7. This type of in-vehicle display board is
It is mainly used on expressways and roads with heavy traffic to inform following drivers of driving information, and is often installed on the loading platform of a truck or the like.

(Problems to be Solved by the Invention) However, there are the following problems with traffic regulation and guidance in special environments such as those around funerals.

In other words, it is not possible to secure a large number of personnel responsible for traffic control among the personnel involved in funeral management, and traffic control and guidance methods may be changed as appropriate depending on the location and time of the funeral. If someone is not used to guiding people, it may be difficult to provide appropriate guidance depending on the time and place, and there may be cases where it is not possible to maintain safe funeral operations, such as traffic congestion on the roads surrounding the venue.

On the other hand, in-vehicle signs and the like used for general traffic regulation are mainly used to warn other vehicles to avoid encroachment during road construction, cleaning, or handling of traffic accidents. Therefore, although such signs are always suitable for providing information to following vehicles, they may be used differently at different times and places in special circumstances, such as around funerals in high traffic areas. This was inconvenient for displaying information.

In other words, traffic regulation and guidance around funerals includes a wide variety of display contents, including not only warnings to take caution, but also guidance for mourners, parking information, and temporary prohibition of trespassing during the removal of a casket. It becomes necessary.

Moreover, it is also necessary to change the orientation and angle of the sign display surface depending on the location conditions of the venue to convey information accurately. Therefore, with conventional vehicle-mounted sign devices, it is not possible to arbitrarily select such a wide variety of displays and display them according to the location conditions of the venue.

Therefore, the present invention was devised to solve the above-mentioned problems. - It is possible to collect various information under special environments, such as not only regulations on shipping roads but also traffic regulations and guidance displays around funeral halls. To provide an in-vehicle public information display device that is capable of transmitting information reliably while adapting to the time and place, and also allows a small number of people to perform these tasks.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a base plate on a carrier body that is detachably mounted on the roof of a vehicle, and a rotary drive mounted and fixed on the base plate. To achieve this purpose, we installed a rotary disk that rotates horizontally using a device, and also provided a display that can be changed freely and is supported by a lifting device that is fixed to the top surface of the rotary disk so that it can swing upward from the horizontal direction. It will be used as a means to achieve this goal.

(Function) According to this invention, the display body is provided on the base plate of the carrier body which is detachably mounted on the roof of a predetermined vehicle.

This display body is rotated in the horizontal direction by a rotary drive device mounted and fixed on the base plate.

Further, the display body whose display can be changed freely is erected and supported so as to be swingable upward from the horizontal direction by a lifting device fixed to the upper surface of a rotary disk rotated by a rotary drive device.
