Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a road sign code suitable for nighttime road construction.

<Prior art> In conventional construction work, miniature lights inserted into vinyl hoses are flashed at night to prevent danger, but they have the disadvantage of being weak and easily damaged.

<Purpose> Therefore, the purpose of the present invention is to provide a road sign code that is strong and can be used day and night to prevent danger.

<Means for Solving the Problem> As shown in the drawing, the means for solving the problem is to provide light sources 3 connected to the electric wire 1 at appropriate intervals of the cord body 2 covering the electric wire 1, and to connect the light sources 3 and the The periphery is inserted into a colored transparent short tube A, the cylindrical tip of the male screw 4 formed on both sides of the short tube A has a split flange 5, and the cylindrical part of the conical screw main tube 6 is attached to each of the male screws 4. The inner diameter of the split protrusion 5 in the free state (FIG. 2) is slightly larger than the thickness of the cord main body 2, and the conical shape of the colored transparent short tube A is In the screwed and tightened state of the threaded main pipe 6 (FIG. 5), the inner surface 6b of the conical part of the conical threaded main pipe 6 presses against the tip of the split projecting edge 5, and the split projecting edge 5 comes into pressure contact with the cord main body 2,
This prevents relative movement between the split flange 5 and the cord body 2, and electrical connectors 7 are attached to both ends of the cord body 2.

<Operation> In the above problem solving means, the code body 2 is
When the color scheme is used for traffic signs, it becomes a daytime road sign code. Furthermore, when the light source 3 is turned on, it becomes a sign to prevent danger at night.

Note that when the light source 3 is inserted into the colored transparent short tube A and screwed into the tightened state (FIG. 5), the inner surface 6b of the conical portion of the conical threaded main tube 6 comes into pressure contact with the tip of the split protrusion 5, causing the split. Since the shaped flange 5 comes into pressure contact with the cord body 2, the colored transparent short tube A does not move together with the cord body 2. Therefore, the cord body 2 is kept at an appropriate distance by the short tube A. The light source 3 is also protected.

<Example> Hereinafter, an example of the present invention will be described based on the drawings. In this case, a cord body 2 made of a strong twisted synthetic fiber rope (or a cord body made of a flexible pipe) is constructed such that the electric wire 1 becomes the core. The electric wires 1 are formed at appropriate intervals on the cord main body 2.
A light source 3 consisting of a small electric lamp is connected to the light source 3, and the light source 3 and its surroundings are inserted into a colored transparent short tube A colored in a hazard prevention color, and a tube with a male screw 4 formed on both sides of the short tube A is provided. The tip part is a split flange 5, and female threads 6a of a cylindrical part of a conical threaded main tube 6 are screwed into the male threads 4, respectively. The inner diameter of the split projecting edge 5 in its free state (FIG. 2) is slightly larger than the thickness of the cord body 2, and the conical screw main tube 6 is screwed onto the colored transparent short tube A. In the state (FIG. 5), the inner surface 6b of the conical portion of the conical threaded main tube 6 presses against the tip of the split flange 5, and the split flange 5 comes into pressure contact with the cord body 2, thereby causing the split flange 5 and the cord to come into contact with each other. The cord body 2 is prevented from moving relative to the body 2, and electrical connectors 7 are attached to both ends of the cord body 2. 8 indicates a luminous tape.

In the above embodiment, the code body 2
can be made into a daytime road sign code by twisting and twisting dyed waterproof synthetic tree threads for any number of traffic signs, or by constructing pipes of the same color.
Moreover, when the light source 3 is turned on, it becomes a sign to prevent danger at night.

In addition, the light source 3 is inserted into the colored transparent short tube A, and the female screws 6a of the cylindrical portion of the conical screw main tube 6 are screwed into the male screws 4 on both sides of the short tube A, respectively, so that the screws are tightened ( 5), the inner surface 6b of the conical part of the conical threaded main tube 6 presses against the tip of the split flange 5, and the split flange 5 comes into pressure contact with the cord main body 2, so that the colored transparent short tube A does not move together with the cord body 2. Therefore, the cord main body 2 is reinforced at appropriate intervals by the short tubes A, and the light source 3 is also protected.

<Effects of the invention> As is clear from the above explanation, according to the invention,
When the light source and its surrounding cord main body are inserted into a colored transparent short tube and the conical screw bus tube is screwed into the tube, the inner surface of the conical portion of the conical screw bus tube comes into pressure contact with the tip of the split flange, causing the conical screw bus to split. Since the shaped flange presses against the cord body,
As a result, the colored transparent short tubes do not move together with the cord main body, and the short tubes reinforce the cord body at appropriate intervals to make it strong and protect the light source.

In addition, in this invention, electrical connectors are attached to both ends of the cord body, so it is easy to connect the power source and the cord body, and the colored transparent short tube is enlarged and the owner's name and advertisement are written on it. In some cases, they have the effect of preventing theft, and using neon tubes, light emitting diodes, etc. instead of small electric lights as light sources has an excellent effect of increasing advertising effectiveness.
