It is preferable that this type of road sign is designed so that it can be easily installed and removed in accordance with the congestion of the road. Because it is fixed with anchor bolts and the like, when installing and removing it, it was necessary to loosen and tighten the bolts each time, which was very troublesome and time-consuming. In addition, it is necessary to transport the sign object to the site every time it is to be installed, and it is very troublesome to transport and store the removed object. Further, since these operations are performed while regulating roads, they cause traffic stagnation, and there is a risk of a traffic accident itself.

[0004] Therefore, the present invention solves the above-mentioned problems of the conventional road signage by making the signage part protrude from the ground in accordance with the congestion of the road. It does not provide a body.

[0005]

In order to achieve the above object, the present invention has the following arrangement. That is, the road marking body according to the present invention has a tubular portion buried in the ground, and a columnar marking portion that is inserted into the tubular portion and is capable of moving up and down. A guide groove perpendicular to the inner surface and a locking groove at the upper end are formed, and a projection is projected outward on a lower side surface of the marking portion, and the projection is slid into contact with the guide groove to raise and lower the marking portion. In addition, the projection is locked in the locking groove so that the indicator portion is held in an exposed state, and
At the upper end of the cylindrical part, a locking plate is attached so as to cover the projection of the marking part.
It is characterized by being attached by the default .

[0006]

According to the road sign of the present invention, the sign is inserted into a tubular portion buried underground so that the sign can be moved up and down.
When necessary according to the road conditions, the marking portion can be exposed to the ground surface, and when unnecessary, the marking portion can be stored in the tubular portion.

A guide groove perpendicular to the inner surface and a locking groove at the upper end are formed in the cylindrical portion of the road marking body of the present invention, and a projection protrudes outward from a lower side surface of the marking portion. The projection is slid into contact with the guide groove to raise and lower the indicator, and the projection is locked in the locking groove so that the indicator is held in an exposed state. By simply raising and lowering the marking part, the marking part can be easily exposed to the ground surface or housed without any trouble such as tightening.

FIG. 6 is a vertical cross-sectional view showing a state in which the marking portion of FIG. 1 is exposed.

In FIG. 1, reference numeral 1 denotes a column-shaped marking portion.
The material of the marking portion 1 is not particularly limited. However, if the marking portion 1 is made of a synthetic resin such as rubber or soft urethane resin which has flexibility and elasticity, it has excellent flexibility and durability, and Even if one vehicle passes over it, it is preferable because it bends flexibly and is quickly restored, and the impact given to the driver or the vehicle is very small. The shape of the marking portion 1 is appropriately shaped such as a conical shape or a cylindrical shape having a hollow inside, and has a diameter of 30 to 15 mm.
Those having 0 mm and a height of 300 to 1000 mm are generally used.

[0010] A sign 12 is generally provided on a side surface 11 of the sign portion 1. The sign 12 may be provided on the entire side surface 11 by coloring it with, for example, red or orange or the like indicating a danger, or may be provided on an appropriate portion of the side surface 11 by a character, a symbol, a pattern, or the like. Also, a reflector may be attached to improve visibility at night. The reflecting material is a material that retroreflects incident light such as a vehicle headlight. For example, a flexible sheet in which glass beads are embedded on the surface, a fine light-transmitting sheet in a flexible light-transmitting sheet. A cut prism, a reflection prism having a large number of diamond cuts on the back surface of a synthetic resin having good light transmittance, and the like are appropriately used.

As shown in FIG. 2, a projection 13 projects outward from the lower side surface of the marking portion 1. The projection 13 is located on the indicator 1
Although it may be formed by integral molding with the same material as the above, in this embodiment, in order to secure stability and strength, the lower constituent member 14 having the projection 13 protruding from the side is made of steel, aluminum, or the like. The lower component 14 is made separately from metal and is attached to the lower part of the indicator 1 with bolts and nuts 15. In this way, if the marking unit 1 is damaged, only the marking unit 1 can be replaced with a new one. The four projections 13 are provided at 90 ° intervals, but the number is not particularly limited.

3 and 4, 2 is buried underground,
Generally, it is a cylindrical portion made of metal such as steel or aluminum. As shown in FIG. 4, the cylindrical portion 2 is formed in a bottomed cylindrical shape having an opening 21 so that the marking portion 1 of FIG. 1 is inserted into the cylindrical portion 2 so as to be movable up and down. Further, a space enough to completely store the sign portion 1 is formed inside.
On the inner surface of the cylindrical portion 2, the same number of guide grooves 22 as the protrusions 13 of the marking portion 1 are formed vertically from the upper end to the bottom, and at the upper end, the same number of locking grooves 23 as the protrusions 13 are provided. Four pieces are formed between the guide grooves 22 and the guide grooves 22 at 90 ° intervals. The projection 13 is slid into contact with the guide groove 22 to raise and lower the marking portion 1 in the tubular portion 2, and the lower portion of the marking portion 1 is rotated by 45 ° with the lower portion of the marking portion 1 pulled out to the upper end thereof. The projection 13 of the marking part 1 is fitted and locked in the locking groove 23 so that the marking part 1 is held in a state of being exposed on the ground surface.

At the upper end of the cylindrical portion 2, as shown in FIGS.
The locking plate 3 is attached by bolts 31 so as to cover the projections 13 of the marking portion 1 so that the marking portion 1 does not come off from the tubular portion 2. The locking plate 3 and the upper end of the cylindrical portion 2 are provided with a gap equal to or more than the thickness of the projection 13 so that the projection 13 can slide in the gap when the indicator 1 is rotated. ing. An openable / closable lid 4 is attached to the opening 21 of the cylindrical portion 2, and the lid 4 is closed when the indication portion 1 is stored in the cylindrical portion 2. The lid 4 prevents dust, earth and sand from entering the tubular portion 2 and prevents danger and damage even when a vehicle or the like gets on the vehicle.

A method of using the road sign according to the present invention as described above will be described with reference to FIGS. FIG. 5 shows a state in which the marking part 1 is stored in the tubular part 2 when not required. When the marking part 1 is exposed on the ground surface G, the lower part of the marking part 1 is pulled out from the state shown in FIG.
6 and rotate the protrusion 1 of the indicator 1 into the locking groove 23 as shown in FIG.
3 is fitted and locked, so that the indicator 1 is held in a state of being exposed to the ground surface G without descending. Next, when the marking part 1 is to be housed in the cylindrical part 2, the marking part 1 is slightly lifted and rotated by 45 ° to release the locking of the projection 13 from the locking groove 23, and the projection 13 is inserted into the guide groove. As shown in FIG. 5, when the indicator 13 is engaged with the guide 22, the indicator 13 is lowered into the tubular portion 2 by its own weight while sliding the protrusion 13 into the guide groove 22 of the tubular portion 2.

[0015]

As described in detail above, the road sign according to the present invention is configured such that the sign is inserted into the tubular portion buried underground so that it can freely come and go. The marking portion can be exposed to the ground surface when necessary, and can be stored in the tubular portion when unnecessary. Therefore, there is no need to transport or store the sign before installation or after removal as in the related art, and the operation is extremely easy.

A guide groove perpendicular to the inner surface and a locking groove at the upper end are formed in the cylindrical portion of the road marking body of the present invention, and a projection is projected outward on the lower side surface of the marking portion. The projection is slid into contact with the guide groove to raise and lower the indicator, and the projection is locked in the locking groove so that the indicator is held in an exposed state. Therefore, the marking can be easily and quickly completed by raising and lowering the marking part and locking the projection of the marking part in the locking groove of the cylindrical part without troublesome work such as loosening or tightening the bolt as in the conventional case.
