Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection column that is arranged in rows so as to prevent cars from entering a road or lawn. The protection column is a short column around which a moy rope of a ship is wound. It is also used as a decorative short pillar to be installed in a park or the like.

[0002]

2. Description of the Related Art Nowadays, not only in Japan but also in each developed country, the number of vehicles used is increasing, and personal injury due to contact with automobiles is increasing. Under such circumstances, in order to maintain each road, protect sidewalks, and prevent automobiles from entering the parks and buildings on the premises, concrete, stone, wood, metal, etc. are used at a height of about 0.6 m to 1 m. The protection pillars (bollards) are lined up to protect the human body by contact with the car.

[0003]

By the way, the above-mentioned protection columns are provided in various shapes in consideration of harmony with nature, but the purpose is to prevent automobiles from entering various places, and Since it was supposed to be protected, it was merely a row of short columns, and it was not a person who made people happy and comforted.

In view of the above points, the present invention has an object to provide a protective effect to a protection column so that a person can have a good time and comfort.

[0005]

Means for Solving the Problems As a result of earnest studies on means for giving a decorative effect as a protection column, the present inventor found that if a plant is planted on the protection column to form a so-called small flowerbed, a simple row of short columns will be formed. I was convinced that the decorativeness would be much improved compared to the case of the simple case, and that the flowers and greens that lined up could comfort the people's hearts. Therefore, in the present invention, it is decided to provide a protective column in which a planting portion for cultivating and growing a plant is formed on the upper part of the protective column main body.

Here, the reason why the planting part is the upper part of the protection column is that the most noticeable part is preferable in order to exert a decorative effect. In addition, plants planted in this planting section are not limited to flowers and the like, but include shrubs.

However, rather than forming the planting portion fixed to the protection column, that is, forming the upper part of the protection column main body into a tubular shape and using this tubular portion as the planting portion, considering the maintenance point,
A configuration that allows easy replanting is desirable. Therefore,
As the planting section in the present invention, it is also possible to adopt a configuration in which the upper part of the protective column main body is formed in a tubular shape and the planting box is detachably attached to the tubular section.

The protection pillar is installed in a public place such as a road, and the installation place is wide. On the other hand, since the flowers and shrubs planted in the planting section are plants, they need to be hydrated. Therefore, irrigation must be done over a wide area, and the fact that irrigation can be omitted is important for the protection pillar with a planting section. Therefore, in the present invention, the main body of the planting box is divided into an upper plant growing portion and a lower water storage tank portion by the intermediate plate, and the intermediate plate is provided with a water absorbing mechanism for sucking the water in the water storage tank to the plant growing portion. Also adopted the configuration.

[0009] Although the planting box is effective in the season when there are many flowers, the planting box became overgrown at the time of winter withering, when the next flower seedling was not in time, the flowering time of the previous work was over, In some cases, if it can be quickly pulled out from the main body of the protective column and used as a regular protective column, the unsightly appearance of flowers will not be exposed. Therefore, in the present invention, it is also possible to adopt a configuration in which one of the cover body and the planting box that covers the protection column main body can be detachably attached to the tubular portion.

The above-mentioned protective columns are usually fixed to the road surface via anchor bolts or the like. However, in the case of a protection pillar installed on the entry route of a building,
In some cases, it is desirable to have a structure that can be removed so that an automobile can enter. Therefore, in the present invention, it is possible to adopt a configuration in which the protective column main body is removably inserted into the support cylinder immersed in the road surface. Here, the reason why the support cylinder is immersed in the road surface is to prevent it from hindering the traveling of the car, but there is also a technical significance that the support cylinder can improve the stability of the protection pillar. Have.
