JPS5817783Y2 - Eight rolls of cover for road sign tubes - Google Patents

Description

[Detailed description of the invention] This invention is mainly used for road construction and other repair work, in order to ensure the safety of the workers involved and to prevent danger to passersby or passing vehicles. This invention relates to a hemlock-shaped cover used for a cylindrical road sign having the same effect as this.

Conventionally, a large number of sign tubes in a desired shape, such as a conical shape or a pyramid shape, are erected around a so-called road repair site to clearly indicate dangerous zones and ensure the safety of workers and passersby.

Therefore, in order to make it easier to see the sign tube mainly at night, the outside surface of the sign tube is colored with fluorescent paint in an appropriate color, or reflective tape is attached to the outside surface to make the sign tube more effective. I am getting .

These sign tubes are used on roads, where they are exposed to the wind and rain, come into contact with exhaust gas from passing cars and dust in the atmosphere, and are also damaged by passing cars and machinery for road repair work. in the environment.

As a result, the outer surface of the marker tube was stained and the reflective tape pieces of the paint 9 were peeled off and fell off, reducing the marker function and making it impossible.

If the functional part of the marker tube becomes incomplete in this way, the marker tube will be cleaned and repaired.
Repairs had to be made for each sign individually, which was very tedious and time consuming.

In the case of a marker tube that has been used for a long period of time, cleaning is no longer effective, and repair becomes difficult, resulting in the uneconomical need to discard the marker tube itself.

However, this invention provides a hemlock-shaped cover for a road sign tube that solves the above-mentioned problem, namely, this idea has both sides inclined so that one side becomes the small diameter section 1 and the other side becomes the large diameter section. A road sign tube characterized in that a retroreflective material piece 5 having a striped or other conspicuous required pattern 4 is provided on the surface of a cylindrical flexible sheet base piece 3 formed with an opening at the opening 2. This relates to a type of rolled cover.

To describe in detail an example of implementing this invention, a trapezoidal flexible sheet base piece A made of cloth, synthetic resin, etc.
and the other edge 7 are sewn together, and one side is opened into the small diameter part 1 and the other side is opened into the large diameter part 2, and both sides are inclined. A road sign tube formed by sewing a piece of retroreflective material 5 to which a group of glass microparticles consisting of an appropriate number of stripes or other easily noticeable characters or a desired pattern 4 is fixed with a desired adhesive. It is a winding cover.

Such a cover is fitted onto a part of the outer surface of a cone-shaped or pyramid-shaped marker tube 9 with the small diameter opening facing upward and the large diameter opening facing downward, and is fitted and covered from above the front of the marker. It can be used by being attached in a hemlock shape.

According to the cover of this invention, if the cover becomes soiled or damaged and the marking function of the marker tube is reduced or becomes impossible, it can be removed from the marker tube and cleaned, repaired, or replaced. This allows the conventional signage function to be maintained.

Therefore, it is only necessary to clean, repair, and replace the marker tube itself as in the past, which is simple and efficient, and is very economical.

Further, it can be attached to the marker tube extremely easily and reliably without requiring any special fixing means.

According to the present invention, as described above, since the flexible sheet base piece A is formed in a cylindrical shape so that one side has a small diameter and the other side has a large diameter, there are no restrictions on the shape and size of the various marker tubes 9. When attached, it always remains in close contact with the outer circumferential surface of the marker tube, and is sufficiently durable against wind, rain, and other adverse conditions.
Since it is flexible, it can be held firmly as if it were bitten into the outer circumferential surface of the marker tube.

On the surface of the sheet base piece A, strips and other designs that are easily noticeable, especially at night, are formed using pieces of retroreflective material. It reflects very sensitively from vehicle light sources, etc., making it extremely effective in preventing danger.

Furthermore, since it can be attached to and removed from the sign tube 9, the sheet base piece A can be removed when not needed and used alone before the conventional sign, and there is no need to form special processing such as reflective tape on the sign tube body, making it easy to use. It is possible to eliminate the unsightly appearance of the sign tube caused by replacing the tape and overcoating with fluorescent paint.
It has the convenience of being able to be washed and being sufficiently durable for long-term use.

Furthermore, by forming a hanging flat part 8 along the opposite edge of the small diameter part of the cylindrical flexible sheet base piece A,
When a conical sign tube is covered with the cover of the present invention, since both are conical, they come into close contact with each other, causing inconvenience during removal. However, since a flat hanging portion is formed, removal becomes smooth, and the sheet base piece A This makes it easier to carry and remove from the marker tube, and dangerous work on the road can be completed in a shorter time.

If necessary, the same effects as described above can of course be achieved by forming retroreflective material pieces 5 on the entire surface of the sheet base piece instead of using a band-like pattern or the like.
