[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a signboard used for displaying road works and the like.

[0002]

2. Description of the Related Art FIGS. 1 and 2 show a conventional signboard of this type, in which a rectangular display surface support 1 is provided with a display surface 2 which is entirely planar and reflective. The display surface 2 carries visible information 3 such as characters, figures, and symbols. At a portion near the upper end of the display surface support 1, an upper end of a rotation leg 4 is supported rotatably within a predetermined range around a rotation shaft 5 extending in the width direction of the display surface support 1. ing. The vertical signboard is connected to the display surface support 1 and the lower ends of the rotation legs 4 in a state where the rotation leg 4 is opened with respect to the display surface support 1.
Can be set on the installation surface in a state of being inclined obliquely upward.

[0003]

In the conventional signboard of this type, the display surface 2 is used with the display surface 2 inclined obliquely upward as described above. Even if light enters the display surface 2 as shown by the arrow A in FIG. 2, more than 50% of this light is reflected obliquely upward as shown by the arrow B and does not enter the eyes of the driver of the automobile. There was a problem that the visibility and appeal of the signboard were not always sufficient.

[0004] In addition, the weight of the sandbag is connected to the signboard by wire so that the signboard does not fall down due to wind or the like. However, there is a problem that the work is troublesome.

[0005] The present invention has been made in view of such circumstances, and an object of the present invention is to provide a display head that is substantially upright in use during use, so that the head of a car can be used at night. When the light emitted from the light is incident on the display surface, the light reflected toward the driver of the vehicle is increased, so that the visibility and appeal can be significantly improved. An object of the present invention is to provide an upright signboard that can be folded in the same manner as before when it is not used, for example, during transportation.

Another object of the present invention is to provide an upright signboard which can prevent the signboard from falling down due to wind or the like by a very simple operation.

Further objects of the present invention will become clear from the description hereinafter.

[0008]

According to the present invention, a lower surface of a display surface support provided with a display surface for carrying visible information is rotatable about a rotation shaft extending in a width direction. To support. Further, the upper end of the oblique leg is connected to the display surface support, and the lower end of the oblique leg is connected to the base so as to be rotatable around a rotation axis extending in the width direction of the base. The oblique legs can be extended and contracted, and when the display surface support is substantially upright in the vertical direction, the oblique legs incline with respect to the vertical direction, and can support the display surface support with sufficient strength. To do.

[0009] In the signboard support of the present invention, when used, the display surface support, and thus the display surface of the signboard, can be illuminated from the headlights of an automobile at night if the display surface of the signboard is substantially vertically upright. When light falls on the display surface,
While reducing the light reflected upward as in the past,
The light reflected toward the driver of the vehicle can be increased, and the visibility and appealing property can be greatly improved as compared with the related art. (Strictly speaking, the light emitted from the headlight of the vehicle is slightly lower. Since the light is incident on the display surface of the signboard, the light reflected toward the driver is maximized when tilted slightly forward from the full vertical direction, and visibility and appeal can be maximized. ).

Further, in the signboard support of the present invention, the signboard can be prevented from falling down by wind or the like only by placing the weight of the sandbag on the base.

When the display surface support is rotated with respect to the base at the time of non-use such as storage and transportation, the display surface support, the display surface, the oblique legs and the base are substantially substantially mutually separated. It can be folded to be parallel. When the display surface support is rotated with respect to the base in the folding direction, the oblique legs contract and rotate with respect to the base and the display surface support.
