Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a road sign drawing template which can easily draw a road sign displayed on a pavement surface of a road.

[0002]

2. Description of the Related Art In addition to lane markings indicating lanes, various road markings indicating pedestrian crossings, traffic divisions, instructions for turning left and right, regulated driving speed, and the like are drawn and displayed on the surface of a paved road. .

[0003] These road signs are worn by passing vehicles and must be repaired and updated periodically. Conventional road marking drawing work involves cleaning the pavement surface, drawing signs and characters of the road marking on the road surface using chalk, masking the area around the drawing figure, and painting the predetermined color inside the masking. Is applied, and the masking is removed after the paint is solidified. In order to ensure sufficient durability and quick-drying properties, a special paint has been developed which is heated to about 200 ° C. and flows down.

[0004]

In the prior art, prior to the application of the paint, it is indispensable to draw a figure such as a sign or a character of a road sign correctly at a predetermined position on the road surface. The drawing work at this time is extremely time-consuming, requires a high degree of skill, and has a problem that an unexpected personal injury may occur. This is because a worker who is drawing must go out on a road with a lot of traffic and concentrate his attention on one point on the road surface, and often cannot afford to pay attention to surrounding traffic.

SUMMARY OF THE INVENTION In view of the above-mentioned problems in the prior art, an object of the present invention is to eliminate the need for complicated and dangerous drawing work by using a flexible sheet material forming a mold hole, and to draw a road sign. It is an object of the present invention to provide a road sign drawing template that can greatly simplify the operation.

[0006]

The gist of the present invention for achieving the above object is to form a mold hole for forming a road sign in a flexible sheet material.

[0007] A heat transfer material can be attached to the sheet material along the periphery of the mold hole, and the heat transfer material can be a metal foil.

[0008] The sheet material may be provided with a protective material for protecting the heat transfer material.

The sheet material may be a transparent material, and a mark indicating the center position of the mold hole may be displayed on the sheet material.

[0010]

According to the structure of the present invention, the flexible sheet material can be promptly displayed in a predetermined position at a predetermined position through a mold hole by positioning the flexible sheet material on the road surface. it can. Therefore, if paint is applied to the road surface through the mold hole, a predetermined road sign can be easily drawn on the road surface. The heat transfer material attached to the periphery of the mold hole is
The heat from the paint spreads widely, preventing the sheet material from prematurely deteriorating due to the contact of the high-temperature paint, and the protective material prevents the paint from adhering and degrading the heat transfer characteristics of the heat transfer material. To prevent.

The flexible sheet material is preferably a soft or semi-rigid synthetic resin sheet such as polycarbonate or a synthetic rubber sheet. By using a sheet material having a thickness of several mm, the sheet can be made compact during transportation. It can be rolled up, and when used, it can be spread out in a plane and brought into close contact with a road surface with some unevenness. The heat transfer material is preferably a metal foil having a high thermal conductivity such as an aluminum foil or a copper foil having a thickness of about 0.05 to 0.3 mm. 3 ~
It is good to attach to 10cm width. In addition, the protective material uses adhesive gum tape, cloth tape, Teflon tape etc. that paint is difficult to adhere, and covers the entire surface of the heat transfer material,
It is sufficient if the bonding is made several cm wider than the width of the heat transfer material.

When the sheet material made of a transparent material is spread on the road surface, the road surface can be seen through the sheet material, so that the positioning of the entire sheet material including the mold holes is easier.

Further, if a mark indicating the center position of the mold hole is displayed on the sheet material, the mark can be used to further facilitate the positioning of the sheet material.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

The drawing template of the road sign forms a mold hole 11a for forming the road sign in the sheet material 11,
The heat transfer material 12 is mounted on the entire circumference of the mold hole 11a, and the protection material 13 is additionally provided (FIGS. 1 and 2).

The sheet material 11 is, for example, a soft or semi-rigid flexible transparent polycarbonate sheet, and preferably has a thickness of about 2 to 5 mm. However, the sheet material 11 may be any synthetic resin material or synthetic rubber material other than polycarbonate, and may be transparent or opaque. In addition, it is preferable to improve the heat resistance of the synthetic resin material containing polycarbonate by subjecting it to a crosslinking treatment, a polymerization treatment, a radiation treatment or the like.

The mold hole 11a is formed in a shape that forms a road sign displayed on the road surface. Therefore, the mold hole 11a
It may be an arbitrary symbol other than the illustrated arrow or a figure such as a character.

A heat transfer material 12 and a protection material 13 are continuously mounted on the periphery of the mold hole 11a.

The heat transfer material 12 is a metal foil such as an aluminum foil or a copper foil, and is mounted so as to wrap both sides of the sheet material 11 through a mold hole 11a. The width W2 of the heat transfer material 12 is determined to be approximately 3 ≦ W2 ≦ 10 (cm). On the other hand, the protective material 13 is an adhesive tape such as a gum tape or a Teflon tape, and is adhered to the heat transfer material 12 and the sheet material 11 so as to cover the heat transfer material 12. The width W3 of the protective material 13 is preferably set to about W2 + 2≤W3≤W2 + 10 (cm) with respect to the width W2 of the heat transfer material 12.

The drawing template can be compactly rounded when not in use, such as during transportation or storage. This is because the sheet material 11 has flexibility.

The drawing template is spread at a predetermined position on the road surface R (FIG. 3), and the paint P from the coating machine M is injected into the mold hole 11a to form the mold 1 on the road surface R.
A road sign having the same shape as that of the road sign 1a can be easily drawn.
The applicator M holds the paint P by heating it to about 200 ° C., and opens the shutter M1 to hold the paint P.
Can be moved laterally along the road surface R while flowing down (in the direction of arrow K in the figure). However, instead of the flow-down type in which the paint P flows down, the coating machine M may be a spray type in which the paint P is sprayed in a mist state.

Incidentally, marks 11b, 11b... Indicating the center position of the mold hole 11a may be displayed on the sheet material 11 (FIG. 4). However, the marks 11b, 11b.
1a are displayed at both ends of the vertical and horizontal center lines C1 and C2. Therefore, the sheet material 11 has marks 11b, 11b,.
Is used, it is possible to easily position the entirety on the road surface R at the display position of the road sign.

The heat transfer material 12 and the protection material 13 are not always necessary when the heat resistance of the sheet material 11 is sufficient, and may be omitted.

[0024]

As described above, according to the present invention, by forming a mold hole in a flexible sheet material,
By expanding the sheet material on the road surface, a predetermined road marking figure can be quickly displayed on the road surface, so that complicated and dangerous drawing work on the road surface can be eliminated, and the drawing work of the road sign can be omitted. There is an excellent effect that simplification can be greatly simplified and high efficiency can be achieved.
