Abstract

(57) [Problem] To provide an in-vehicle warning signage device and a warning signage vehicle which are hard to fall down due to wind pressure during traveling even when moving at a high speed and are hard to fly. The apparatus includes a stage mountable on a vehicle chassis capable of traveling, a warning sign board disposed on the stage, and a direction switching mechanism for switching an arrangement direction of the warning sign board on the stage. The direction switching mechanism is configured to determine a first switching position in which the warning sign board is turned in a direction in which wind pressure against the warning sign board on the mounting stage during vehicle running is small, and visibility to the warning sign surface from the ground outside the vehicle. The warning sign board is rotatable between a second switching position in which the warning sign board is oriented in a secure direction.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an in-vehicle warning sign device and a warning sign device which are arranged beside a road at the time of road construction or a traffic accident, and display a warning to a driver of an approaching vehicle.

[0002]

[Prior art]

 When constructing roads or handling traffic accidents, it is necessary to accurately point out the driver's path to the driver of the following vehicle. In many cases, a number of road signs with reflectors reflecting headlights with arrows indicating the route to be taken are installed on the road at intervals from just before the accident site to just before the accident site. .

[0003]

[Problems to be solved by the invention]

 By the way, especially in the handling of traffic accidents, in order to prevent a secondary disaster such as a rear-end collision with the accident vehicle by a subsequent vehicle, rush to the accident site and promptly cause an The vehicle must be signaled and a warning must be given to reduce speed and change lanes.

[0004] Thus, it is conceivable to install a warning display plate on a vehicle chassis such as a truck that can travel, but as described above, it is necessary to rush to the accident site. At this time, if the warning sign is inadvertently mounted, it is expected that the vehicle will fall or be blown off by the wind pressure during traveling.

An object of the present invention is to provide an on-vehicle warning sign device and a warning sign vehicle that are hard to fall down or be skipped by wind pressure during traveling even when moving at high speed.

[0006]

[Means for Solving the Problems]

 An in-vehicle warning sign device according to the present invention includes a stage mountable on a movable vehicle chassis, a warning sign plate disposed on the stage, and the warning sign on the stage. A direction switching mechanism for switching an arrangement direction of the sign board, wherein the direction switching mechanism is provided with a first switch for turning the warning sign board in a direction in which the wind pressure on the warning sign board on the mounting stage during traveling of the vehicle decreases. The warning sign board is rotatable between a position and a second switching position in which the warning sign board is oriented in a direction for ensuring visibility of the warning sign surface from the ground outside the vehicle.

According to a second aspect of the present invention, there is provided an in-vehicle warning sign device further comprising an illuminating device for illuminating a warning sign surface of the warning sign plate according to the first invention.

[0008] According to a third aspect of the present invention, there is provided an in-vehicle warning sign device, wherein the illuminating device according to the second aspect includes a plurality of lighting elements and a control device for sequentially blinking the plurality of lighting elements. It is provided.

According to a fourth aspect of the present invention, there is provided a warning sign vehicle equipped with the on-vehicle warning sign device according to any one of the first to third aspects.

[0010]

[Embodiment of the invention]

 In the present invention, a stage mountable on a vehicle chassis capable of traveling, a warning sign board arranged on the stage, and a direction switching mechanism for switching a direction of arrangement of the warning sign board on the stage are provided. The direction switching mechanism is provided with a first switching position for turning the warning sign board in a direction in which the wind pressure on the warning sign board on the mounting stage decreases when the vehicle is traveling, and visibility to the warning sign surface from the ground outside the vehicle. The warning sign is rotatable between a second switching position in which the warning sign is oriented in a direction to secure the warning sign. It becomes difficult to fall or be blown off by wind pressure.

The vehicle on which the stage of the in-vehicle warning sign device of the present invention is mounted may be any vehicle that can travel on public roads, and is capable of being driven by a self-propelled vehicle equipped with an engine or a towing vehicle. Vehicle. Such a vehicle is equipped with an in-vehicle warning sign device including a stage and a warning sign plate erected on the stage.

[0012] The direction switching mechanism according to the present invention includes a first switching position in which the warning sign board is directed in such a direction as to reduce the wind pressure on the warning sign board on the mounting stage during running of the vehicle, and a warning from the ground outside the vehicle. The warning sign board is rotatable between a second switching position in which the warning sign board is oriented in a direction for ensuring visibility with respect to the sign surface. This switching mechanism can have any structure as long as it can switch between the first switching position and the second switching position. For example, a mechanism in which a turntable is provided on a stage and a warning sign board is mounted thereon may be used, a mechanism in which the stage is rotated via a bearing or the like on an axis serving as a center of rotation, or a disk below the stage. A mechanism in which a stage-shaped rail is laid in advance and the stage is rotated by wheels rotating on the rail may be used.

The warning sign board of the present invention is a plate having a warning sign surface. The warning sign surface of the warning sign plate may include a reflecting plate for reflecting light of a headlight or the like so that the driver can recognize the light well. Further, a device provided with a lighting device for illuminating a sign surface of a warning sign plate, more preferably a device provided with a plurality of lighting elements and a control device for sequentially blinking the plurality of lighting elements May be. In particular, those that include a lighting device and include a function to blink a large number of light bulbs in order to indicate the blinking flow can enable the driver of the following vehicle to be well recognized and to quickly change lanes. It is highly expected to encourage change.

【Example】

 FIG. 1 is an explanatory view showing the outline of the configuration of an embodiment of a vehicle warning sign device of the present invention. FIG. 2 is a front view of the on-vehicle warning sign device of FIG. FIG. 3 is a side view of FIG. FIG. 4 is an explanatory diagram showing a configuration of an embodiment of a warning sign vehicle in which the on-vehicle warning sign device shown in FIG. 1 is mounted on a vehicle.

As shown in FIG. 1, the on-vehicle warning sign device 10 includes a stage 11 composed of several frames, and a warning sign plate 12 erected on the stage. The stage 11 is mounted on a bed 42 of a truck 41, for example, as shown in FIG. The carrier 52 and the stage 11 are firmly fixed to each other by wires, bolts and the like (not shown).
