Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truncated long conical or pyramid-shaped road sign, in which an illuminating light, a flash signal light, a reflector or the like is stably mounted in an upper hole thereof. Also, the present invention relates to a method for manufacturing a road sign that can be stably held by inserting an illuminating light or a flash signal light downward in the sign, and can be turned on and blinked inside.

[0002]

2. Description of the Related Art Conventionally, a road sign made of a synthetic resin having a hollow long conical shape or a hollow long pyramid shape has been frequently used as a sign for ensuring safety in road works and the like. In many cases, it is necessary to attach a flash signal light, a reflector, or the like.

In such a case, the signal light is conventionally attached to the head, or the head is cut horizontally, and a mounting tool is attached thereto, and the signal light is supported by the mounting tool. However, the former has a problem that the signal light is unstable, and the latter has a problem that the mounting of the mounting tool is costly and troublesome.

[0004]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention, of course, can stably mount an illuminating light, a flash signal light, or a reflecting mirror on the upper part.
An object of the present invention is to provide a method for manufacturing a road sign having a structure in which a flash signal light can be stably held in a state where the signal is inserted downward into a sign and can be turned on and blinked inside. .

[0005]

SUMMARY OF THE INVENTION The object of the present invention is to provide a method of manufacturing a road sign according to the present invention, comprising the steps of: forming a top portion of a road sign body formed of a synthetic resin into a hollow long cone or pyramid shape; After cutting and softening the cut upper part, the softened upper part is folded inward by press-fitting a molding core from the top side to form a folded wall.

That is, the road sign of the present invention is formed by cutting the top of a conventional synthetic resin long conical road sign into a truncated long conical shape, and heating the upper portion of the road sign with a heated molding rod. After bending the rod, press the rod downward into the sign, or, after heating and softening the upper part inward, press the rod in the same manner as above. As a result, the folded wall is formed inside the truncated top, so that it can be manufactured by simple processing.

That is, in the road sign according to the method of the present invention, since the folded wall formed at the top of the truncation has elasticity, they can be firmly supported by press-fitting the lower part of the illuminating light, the flash signal light, or the reflecting mirror. As a result, the stability is good, and the flash light part of the flash signal light is inserted downward into the sign and the handle part is pressed against the folded wall, so that the flash light is turned on inside the sign stably be able to. In addition, if the formation part of the folded wall formed on the upper part of the road sign is slightly higher than the upper mold line of the ready-made road sign, the whole balance is obtained and the appearance is good.

[0008]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view of a main part of an example of the road sign of the present invention, FIG.
Is a front view showing an example of a use state, and FIG. 5 is a front view of a conventional sign.

In FIG. 5, reference numeral 1 denotes a conventionally used FIG.
A truncated long cone-shaped road sign body formed by cutting the top 1t of a hollow long cone-shaped road sign Uc made of synthetic resin illustrated slightly above the mold line 1a as shown in FIG. A folded wall formed by folding, 3 is a cut portion provided at the lower part of the sign main body 1, 4 is a seat plate provided at the bottom, and constitutes an example of the road sign Uc 'shown in FIG. I do. The present invention is also applicable to a hollow long pyramid shaped road sign.

The road sign Uc 'constructed as described above is:
As shown in FIGS. 3 and 4, the handle 5a of the flash signal light 5 and the handle 6a of the reflecting mirror 6 are pressed into the folded wall 2 and used, or as shown in FIG. Flash signal light 5
Is inserted downward into the sign main body 1 from the top hole formed by the folded wall 2 and the main body of the signaling lamp 5 is pressed into the folded wall 2 and held by the folded wall 2, and the flash signaling lamp 5 is moved to the marker main body 1. It is used for lighting and blinking in the inside. The folded wall 2 is used for the body of the flash signal light 5, the handle 5a,
Alternatively, since the handle 6a of the reflecting mirror 6 is firmly held from its outer periphery, it can be used in a stable state.

As shown in FIG. 2, the road sign of the present invention is manufactured by cutting the top 1t of an existing long-cone shaped road sign Uc slightly above the mold wire 1a as shown in FIG. Then, while the upper wall of the main body 1 is bent inward by a heated molding rod (not shown) or the like, the rod is pressed down into the marker 1. ,
Alternatively, the truncated upper wall of the main body 1 is heated and softened, and then bent inward, and then a shaping rod is press-fitted in the same manner as described above to form the folded wall 2. According to the present invention, the top 1t of the existing road sign Uc is cut from slightly above the mold wire 1a to form a hole 1b, and the hole 1b is inserted into the hole 1b as shown in FIGS.
The handle 5a of the flash signal light 5 and the handle 6a of the reflecting mirror 6 shown in FIG.
May be inserted and used. In this case, the flash signal light 5 can be inserted and used in the opposite direction.

[0012]

The present invention is as described above. In a road sign formed by molding a synthetic resin into a hollow long cone or a long pyramid shape, the top is cut off and the truncated upper wall is placed inside the road sign. To form a truncated road sign by forming a folded wall, so that if a flash signal light or a handle of a reflector is pressed into a ceiling hole formed by the folded wall, it is firmly held by the folded wall. Therefore, the flash signal light can be used in a stable state. In particular, by inserting the flash signal light downward in the sign body and lighting it, the sign function can be significantly improved.

Further, the truncated road sign according to the present invention sequentially cuts a top portion, bends the inside of the upper portion after cutting, and press-fits a rod for molding to an existing long-cone road sign. In addition, since the mold can be manufactured very easily without separately manufacturing, a new mold dedicated to the truncated sign is unnecessary, and therefore, it can be manufactured and provided at a low price. Furthermore, if the existing road sign is used with the head cut, the manufacturing time can be further reduced.
