Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention relates to a sign that is erected on the road surface and used as a safety sign during road construction, etc.

(Prior art) In general, signs erected on the road surface to indicate road construction sites, etc. are composed of a conical sign body and a base that constitutes the lower part, and are easy to transport and store. It is conveniently light in weight. However, because such signs are light in weight, when they are placed on the road, they are easily moved from their designated positions by wind pressure, vibrations, or other light shocks caused by passing cars. There were problems with it moving or falling over.

Therefore, in order to solve the above-mentioned problems, conventional methods have been to make the inside of the base hollow and fill it with heavy objects such as water or sand only when in use, or to place metal etc. as a weight on the top of the base. In some cases, the lower part of the sign was made heavier by attaching a cylindrical body, or by attaching a bolt to the bottom of the base and screwing a weight onto the bolt.

In addition, as prior art, for example, Utility Application No.
Microfilm No. 54465 (Japanese Utility Model Application Publication No. 55-154713) discloses a device in which a weight is provided on a support base that is formed to protrude outward from the bottom of a display section.

(Problem that the invention aims to solve) However, when using such a sign, it is necessary to fill the base with water, sand, etc., or attach a weight, so it is time-consuming to place the sign. Not only this, but there was also the hassle of having to carry heavy items such as water and sand, as well as accessories such as weights, in addition to the sign.

In addition, especially when the wind is strong and the weight is too light, the sign sometimes moves from a predetermined position or falls over.

Structure of the invention (means for solving problems) The present invention is a sign body in which the sign body and its base are integrally molded, and a weight is embedded and fixed in the base. The main idea is to provide a hollow filling part that can accommodate heavy objects such as sand and sand so that they can be taken in and out as desired, and a ring-shaped ring weight is molded to easily adjust the stability.

(Operation) When using the sign constructed as described above, it is erected on the road surface at a construction site, etc. Then, since the ring weight is attached to the base, the sign can be stably erected.

In addition, if the ring weight alone is too light due to particularly strong winds, fill the filling part of the base with water or sand to prevent the sign from moving from its designated position or falling over, and to make it easier to adjust the stability. It has the following effects.

(Example) Hereinafter, an example embodying the present invention will be described with reference to the drawings.

Reference numeral 1 denotes a hollow sign body having a conical shape with an open bottom end, and is molded from a synthetic resin material such as polyethylene or polypropylene. Reference numeral 2 denotes a rectangular base formed integrally with the lower outer periphery of the sign body 1, and the inside thereof serves as a filling part 3 for filling with water or sand.

5 is an opening formed in a part of the upper surface of the base 2 for filling and discharging water, sand, etc., and 6 is a lid for closing the opening 5.

Reference numeral 7 denotes a ring weight made of a solid metal body molded on the inner bottom surface of the base 2, and is designed to increase the weight of the lower part of the sign body. The ring weight 7 is integrally molded with the sign body 1 and the base 2 when they are resin-molded.

Now, when the sign constructed as described above is erected on the road surface R at a road construction site, etc., the ring weight 7 is attached to the base 2, so that the sign remains stable on the road surface R. You can stand it upright. Therefore, there is no need to fill the marker with heavy materials such as water or sand to increase the weight of the marker, or to attach other weights, and the placement of the marker does not require much effort.

In addition, if the wind is particularly strong and the ring weight 7 alone is too light, the opening 5 of the base 2
The filling part 3 is filled with water and sand. In this way, the weight of the sign becomes even heavier, so even if wind pressure, vibration, etc. are strong, the sign will not easily move from its predetermined position or fall over.

In addition, since the sign body 1 is hollow, when the signs are to be put away, they can be stacked one after another by covering the top sign with the bottom sign, which requires a large space. Never.

It should be noted that the present invention is not limited to the above-mentioned embodiments, but can be modified as follows.

For example, in the above embodiment, the ring weight 7 is made of solid metal, but it may also be made into a pipe and filled with heavy objects such as sand, or made of ceramic, cement, etc. instead of metal. good.

Further, the sign body 1 and the base 2 are not limited to being made of plastic, but may be made of rubber.

Effects of the Invention As detailed above, the present invention has the effect that the sign can be erected easily and stably without using any weight.

In addition, if the wind is particularly strong and the ring weight alone is too light, fill the filling part of the base with water or sand as appropriate to prevent the sign from moving or falling due to wind pressure and vibration, and adjust its stability. It is easy to transport, install, and handle.

Claims (1)

[Scope of utility model registration request] The sign body 1 and its base 2 are integrally molded, and a weight is embedded and fixed in the base 2, and heavy objects such as water and sand can be put in and taken out of the base 2 as desired. This sign is characterized in that it has a hollow filling part 3 that can be accommodated in a container, and a ring-shaped ring weight 7 is molded so that the stability can be easily adjusted.
