Description

The present invention provides a flexible elastic column that restores to its original state after being deformed by contact with a vehicle, such as a columnar road sign that stands along the roadway or a bollard that is installed in a parking lot. It relates to a cover body that can be attached.

When columnar members are used for road markings that are erected on the road or for car stops that are erected in parking lots, the columnar members are made of elastic material in order to prevent breakage when the vehicle comes into contact. The method of doing this has been used conventionally. For example, in Patent Document 1, a base portion, a main body cylinder formed of a cylindrical hollow columnar body formed separately from the base portion, and a cylindrical shape having an outer diameter smaller than the inner diameter of the main body cylinder are formed. The main body cylinder and the reinforcing cylinder have the flexibility to elastically bend due to contact with a vehicle or the like, and the upper surface of the base portion has a large annular groove and a small annular groove recessed downward. Are concentrically arranged and formed, and the lower end of the main body cylinder and the lower end of the reinforcing cylinder are inserted into and fixed to the large annular groove and the small annular groove, respectively, and the outside of the macrocyclic groove. A road characterized in that the side wall is formed higher than the annular wall portion formed between the large annular groove and the small annular groove, and the annular wall portion is formed higher than the inner side wall portion of the small annular groove. The composition of the marking body has been proposed by the applicant.

Further, a cover member used by attaching to a columnar member to be installed on a road is also used. A configuration of a pole-type line-of-sight guide cover has been proposed, which comprises a wing portion extending toward the direction and expanding the viewing width of the pole-type line-of-sight guide.

The pole-type line-of-sight guide cover shown in Patent Document 2 improves its visibility by means of a wing portion extending outward, but an elastically flexible pillar portion as shown in Patent Document 1 is formed. When attached to the columnar member to be provided, the cover member may be damaged due to contact with a vehicle or the like.

The present invention provides a cover body that is not easily damaged even when attached to a columnar member made of an elastic material and used.

In order to achieve the above object, the present invention has the following configuration.
That is, the cover body according to the present invention is a cover body that can be attached to an elastic column having flexibility that restores the original state after being deformed by contact with a vehicle or the like.
It is provided with a tubular main body portion in which the pillar portion of the elastic column is housed, and an extension portion protruding outward from the main body portion.
The main body has flexibility to cope with the deformation of the pillar.
The expansion portion includes a narrow portion provided with a smaller protrusion size to the outer side, and the narrow portion is formed at the lower end of the expansion portion and is arranged at the lower portion of the main body portion. It is characterized by.

Since it is provided with a tubular main body for accommodating the column portion of the elastic column and an expansion portion protruding outward from the main body portion, the column portion is stored and attached to the inside of the main body portion of the cover body. The extension portion protruding outward and laterally is suitably visible to the vehicle driver and the like, and the visibility is improved.
Further, since the main body has the flexibility to cope with the deformation of the pillar, the main body is less likely to be damaged when the vehicle or the like comes into contact with the pillar and is deformed.
Further, since a narrow portion having a smaller protrusion size to the outer side is provided in the expansion portion, a portion where the narrow portion provided with a smaller protrusion size is formed in the portion where the expansion portion is formed. Is more easily deformed than others. Then, since this narrow portion is formed at the lower end of the expansion portion and arranged at the lower portion of the main body portion, the narrow portion is easily arranged at the base of the pillar portion in a state where the cover body is attached to the elastic column. Be done. For this reason, when a vehicle or the like comes into contact and the pillar portion is deformed so as to bend at the root, the deformation of the lower part of the main body portion in which the narrow portion is arranged is less likely to be hindered by the expansion portion, and the main body portion is damaged. It is suppressed.

Further, if the expansion portion is not formed at the lower end of the main body portion, the deformation of the lower portion of the main body portion is less likely to be hindered by the expansion portion, so that damage to the main body portion is suppressed.

Further, if an upward cut-shaped portion is formed at the lower end of the main body portion, the main body portion in the vicinity of the cut-shaped portion is provided so as to be more easily deformed, so that the cover body can be attached to the elastic column. When a vehicle or the like comes into contact with the pillar and the pillar is deformed so as to bend at the root, damage to the main body is suppressed.

Further, if the cut-shaped portion is formed by arranging it directly below the extended portion, the main body portion can be more easily deformed in the vicinity of the cut-shaped portion, so that the cover body is attached to the elastic column. In this state, damage to the main body is suppressed when a vehicle or the like comes into contact and the pillar is deformed so as to bend at the root.

Further, the main body portion is formed in a tubular shape whose inner diameter increases from the upper side to the lower side, and when attached to an elastic pillar, the distance between the outer surface of the pillar portion and the inner side surface of the main body portion is provided larger below than above. If it is formed in this way, the work of accommodating the pillar portion inside the main body portion can be performed more easily.
