DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road sign which is allowed to stand on a road to sense its presence. Such a road sign is used for a warning of the presence of a broken vehicle, a display of the presence of a dangerous substance, the formation and display of a road boundary, the separation of lanes, the display of a construction area, and the definition and display of a dangerous zone.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional road marker includes a base 61 for stably standing on a road surface,
The display unit 62 stands upright from the base unit, and the base unit 61 and the display unit 62 are integrally formed.

[0003]

However, since the base portion 61 and the display portion 62 are integrally formed of a hard synthetic resin material, the base portion 61 and the display portion 62 cannot be folded and have a constant and constant volume. In order to reduce the volume during transportation as much as possible, the display portion 62 is formed in a hollow conical shape and can be fitted to each other in the longitudinal direction. However, a large gap is provided between each road sign. As a result, the stacking length becomes long, and the bonding state is very unstable. Therefore, when urging the required number of road signs to the destination, a truck with a large loading capacity such as a truck is required, and a large dead space occurs when transporting by truck or the like, and the cargo is likely to collapse. There is a problem.

In addition, when a person carries a plurality of products in a stacked state, it is necessary to hold them with both hands, so that there is a problem that clothes and the like become dirty. Further, in order to prevent a fall due to a strong wind or the like during use, an annular weight 63 is fitted on the display section 62 and placed on the base section 61 as shown by a chain line in FIG. The handling and management of this weight is complicated.

In view of the above problems, it is an object of the present invention to provide a road sign which can be folded and stacked thinly when not in use, and which can carry a large number of sheets simultaneously with a minimum volume.

It is another object of the present invention to improve the alertness of a remote person during use while standing on a road.

It is another object of the present invention to make it easy to carry a plurality.

[0008]

In order to achieve the above-mentioned object, a road sign according to the present invention is designed to rotate two legs from a state of crossing at the center in the longitudinal direction to a state of overlapping in a single character. A movable erect isosceles triangular display plate is provided on the upper surface of one leg at the lower side, and a straight line connecting the vertex of the display plate and the center of the lower side is on the rotation axis of the two legs. In the upper surface of the other leg, two half-triangular display plates obtained by dividing the hollow erect isosceles triangle into two along a straight line connecting the apex thereof and the center of the lower side are provided on the lower side thereof. In the above, the two dividing lines are fixed in a state of being present on the rotation axis of the two legs, and furthermore, each semi-triangular display plate and the isosceles triangular display plate are joined by a hinge at the upper part. Become.

[0009]

When the two legs are rotated in a cross shape, the display panel having a hollow erect isosceles triangle opens in an orthogonal state. When a predetermined color is displayed on the display panel or when the display panel emits light, its presence can be recognized from the front, rear, left, and right directions.

When the two legs are turned so as to form a single character, the display plates are overlapped and folded in a flat state.

[0011]

Next, an embodiment of the present invention will be described with reference to the drawings. The road sign according to the present invention is attached to a plurality of display panels 1 and 2, hinges 3a and 3b for pivotally opening and closing each display panel, and a bottom side of each display panel as basic components. It has legs 4 a and 4 b and a locking member 5.

The display plates 1 and 2 reflect sunlight or illuminating light irradiating the front and back surfaces to make the presence of the display plates perceptible to a distant person. It has been subjected. For this purpose, paint or a fluorescent paint may be applied to the metal display panel, or a colored synthetic resin sheet having diffuse light reflection may be attached,
The display plate may be formed of a colored synthetic resin material, or a metal plate colored by, for example, a chemical treatment may be used.

Each of the display panels 1 and 2 is formed into an erect isosceles triangle, and the display panel 2 is divided into two parts 2a and 2b along a straight line connecting the vertex and the center of the base.
a, 2b are brought into contact with one of the display panels 1 so as to intersect along a straight line connecting the vertex of the one of the display panels 1 and the center of the bottom of the display panel 1, and the upper part of each divided piece 2a, 2b and one display The plate 1 is pivotally connected to the plate 1 by a hinge 3a so as to be freely opened and closed.

A shaft 3b that connects the bottom sides of the display plates 1 and 2 to the legs 4a and 4b and rotatably connects the intersections of the legs 4a and 4b has the same function as the hinge 3a.

When the display plates 1 and 2 are open, the bottom sides of the display plates are on a common plane as shown in FIG. 1, and when the display plates 1 and 2 are closed, as shown in FIG. The plates 1 and 2 overlap each other in a single sheet and become thinner.

The legs 4a and 4b are preferably made of a metal material and are fixed to the bottom of each display panel. Display boards 1, 2
Is made relatively thin, has a relatively large surface area, and is easily exposed to wind when using this road sign, so the role of this leg is to lower the center of gravity to increase stability and prevent it from falling over easily In addition, to protect the display panel by receiving the force applied by the operator when opening and closing each display panel, and to enable the display panel to be easily opened and closed, the required weight and strength are required. It has. The legs 4a and 4b may be formed of hard plastic into a cylindrical shape and filled with sand or the like serving as a weight.

Furthermore, the legs 4a and 4b receive wind while the road marking body is still standing, even if the road marking body has some unevenness. As shown in FIG. 3, at least both ends of at least one leg 4a are provided with a non-slip member 4c made of a material having a large coefficient of friction, such as rubber, so as not to slide on the road surface when Are protruded and fixed. In the illustrated preferred example, both ends of the other leg 4b are machined in a sawtooth shape,
A non-slip member 4d is formed.

When the sign is opened to a required angle, a locking member 5 is attached to the other leg to keep the opening angle constant. In the first embodiment, at least one of the legs 4b is formed of a locking edge that comes into contact with the side surface of the other leg when the legs are rotated to a predetermined angle.

The display panel is provided with a support hole 6 for facilitating the carrying of the road sign. When the road sign is folded flat, the road sign can be carried and carried in the hand-held hole.

With the above structure, as shown in FIG. 2, the road sign body folded in a flat state is now lifted up so as to intersect each other with the two legs 4a and 4b in a parallel state. When opened, the display plates 1 and 2 are expanded as shown in FIG. When the locking member 5 is opened to a predetermined angle, the locking member 5 is stopped on the side surface of the other leg 4a and cannot be further opened. In this way, the display boards cross each other, and this road sign is attached to the legs 4.
The non-slip members 4c and 4d can be left on the road surface. In the stationary state, the display surface of the display panel is turned in the front, rear, left, and right directions.

Therefore, if the display surface is coated with a paint or fluorescent paint of an eye-catching color, or a colored sheet having diffuse light reflection is attached, or if a color-developing process is performed, the display surface is The reflected light is visible even to a distant person, and the presence of the road sign is perceived.

If such a road sign is kept in a car or the like, it can be installed on a rear road surface while parking due to a failure on the road, and call attention to another vehicle.
In addition, when a plurality of road signs are arranged on a road surface with an appropriate distance, lane separation and boundary formation / display, for example,
It is possible to easily perform the sectioning / displaying of the off-limits area at the traffic accident site, the sectioning / displaying of the danger area at the construction site, and the like.
By passing through connecting members such as rods, ropes, chains and the like and connecting them, a protective fence can be obtained.

When the role as a road sign has been completed, the connecting member is removed, and the legs 4a and 4b are first rotated about the shaft 3b in the direction in which the legs approach each other. Close until they overlap each other. In the closed state, the carrying holes 6 of the respective display panels match, so that the user can carry the road signage to the carrier by placing his hand through the carrying holes and put it on it. When using a large number of road signs, such as construction, for example,
It can be carried to a truck such as a truck or a motorcycle, and stored or stacked in a flat state in close proximity to a storage box or the like prepared in the truck.

The road markings have no thickness in the closed state, and all the road markings are folded in the same shape, so that the storage volume or the loading volume is much smaller than the conventional products. Therefore, for example, when an emergency lane change, division, or display is required at the site of a traffic accident, the minimum number of road signs should be stored in a case attached to a motorcycle, etc. Expand the sign, leave it on the road,
Accident handling can be performed quickly and safely.

In addition, for example, in the event of a gas leak accident or the like, even when a protective fence for entering and exiting a manhole provided on a roadway is to be quickly formed, it is necessary to transport the road sign by motorcycle or the like. it can.

For example, when arranging road markings over a long distance, such as in road construction, the number of road markings that is several times the number of road markings is increased by using a transport vehicle having the same loading capacity as the conventional one. It has the advantage of being transportable.

When the display plates 1 and 2 are formed as hollow erect isosceles triangles as shown in the figure, there is an effect of saving material and an effect of preventing a fall by letting out wind force. Further, by utilizing a space created between the upper and lower hinges 3a, 3b, it is possible to provide a windmill-type rotary display 41 as an alert means there as illustrated in FIG. Since the change in the light reflection direction due to the rotation draws more attention, the appealing power (the power to perceive the existence) is improved. In this case, as the rotary display body 41, a single blade having a substantially S-shaped cross section is used so that the rotary display body 41 is substantially in the same plane as the display plate when folded. The upper and lower bearings 42 and 43 of the rotary display are fitted and fixed to the display plate in the open state. A thrust bearing is used for the lower bearing 43.

Further, a power source such as a dry battery may be accommodated in the space of the leg 4a, and a luminous body which emits light continuously or blinks red or the like using the power source may be provided in the space between the display panels. . The one provided with such a luminous body is effective for night use.

[0029]

As described above, according to the present invention, the display panel is oriented in the front-rear and left-right directions by holding the legs and expanding to a cross shape, thereby providing a wider area than the conventional conical shape. The visibility is remarkably improved. In addition, the display panel can be folded flat by turning the legs in the opposite direction, so that the amount of handling once in the folded state can be increased and the loading capacity can be reduced.
