Description

  The present invention relates to a bollard used as a vehicle stop for a road, a parking lot, a park, etc. and a covering member for the bollard.

Conventionally, for example, there are those described in Patent Document 1 and those described in Patent Document 2 as bollards that are installed, for example, at park entrances and the like to prevent intrusion of vehicles and the like.
The bollard described in Patent Document 1 includes a covering member having a gap inside and a pillar member disposed in the gap of the covering member.
The covering member is formed using an elastic material such as a synthetic resin. The column member is formed of a synthetic resin having a hardness higher than that of the covering member. Moreover, the bottom part and the head part of the column member are formed of a synthetic resin having a hardness higher than that of the covering member. Then, the pillar member and the covering member are welded and joined, and the outer peripheral surface of the pillar member is covered with the covering member to form a bollard.
The bollard described in Patent Document 2 includes a cylindrical covering member and a column member disposed inside the covering member.

  The covering member is formed using an elastic material such as a recycled rubber material. As a raw material of the recycled rubber material, for example, a waste tire is used.

(Installation method)
Next, the installation method of the bollard 1 is demonstrated, referring FIGS. 1-8.
For example, when the bollard 1 is installed at a boundary between a park entrance and a roadway, first, the column member 2 is erected on the ground S. In this case, for example, the lower end side of the column member 2 is inserted into the installation hole H provided in the ground S without using a fixing means such as cement, and the column member 2 is erected on the ground S. Thereby, the column member 2 can be removed from the ground S as necessary, for example, when the emergency vehicle is traveling.

Next, the lower end side component 8 is attached to the column member 2, and the lower end side component 8 covers the outer peripheral surface of the column member 2.
After the lower end side component 8 is attached to the column member 2, the lowermost covering 8 is disposed above the lower end component 8 and the spacer 18 with the spacer 18 disposed above the lower end component 8. The member structure part 14 is arrange | positioned.

As described above, after the lower end side constituent portion 8, each covering member constituent portion 14, each spacer portion 18, and each annular member 10 are attached so as to be relatively movable with respect to the column member 2, the upper end side configuration is provided on the column member 2. The part 6 is fixed and the installation of the bollard 1 is completed.

(Function)
Next, the operation of the bollard 1 will be described with reference to FIGS.
In the environment where the bollard 1 is installed, for example, a vehicle traveling on the roadway in the boundary between the park entrance and the roadway runs toward the park doorway due to a mishandling, etc. A part of this contacts and collides with a part of the covering member 4. Specifically, the bumper of the vehicle contacts and collides with at least one covering member constituting portion 14 among the plurality of covering member constituting portions 14 stacked in the vertical direction.

Here, when the traveling direction of the vehicle is not inclined or hardly inclined with respect to the tangential direction of the covering member constituting portion 14, that is, when the vehicle collides head-on with the bollard 1, the covering member constituting portion 14, the portion where the vehicle has contacted or collided is deformed toward the gap 22.
At this time, the length along the outer diameter dimension of the spacer 18 is set to be smaller than the outer diameter dimension of the total thickness portion among the outer diameter dimensions of the covering member constituting portion 14. Further, the outer diameter of the annular member 10 is made larger than the outer diameter of the spacer 18 and is smaller than the outer diameter of the covering member component 14.

For this reason, when the covering member constituting portion 14 is deformed, it is possible to suppress the spacer portion 18 from projecting outside than the covering member constituting portion 14. In addition, it is possible to prevent the vehicle in which the covering member constituting portion 14 is deformed from being brought into contact with the annular member 10 and coming into contact with the spacer portion 18.
Therefore, when the vehicle collides head-on with the bollard 1, the portion of the covering member constituting portion 14 that has contacted and collided with the vehicle is deformed toward the inside of the gap portion 22. It can be absorbed and reduced.

Further, since the contact between the vehicle and the spacer 18 is suppressed, it is possible to reduce the impact applied to the vehicle and the column member 2, and to reduce damage to the vehicle and the column member 2.
Moreover, the impact which a vehicle exerts on the covering member constituting portion 14 is reduced by the deformation of the covering member constituting portion 14. For this reason, even if the deformation of the covering member constituting portion 14 proceeds and the vehicle contacts the annular member 10 or the spacer 18, it is possible to reduce the impact applied to the vehicle, the annular member 10 and the spacer 18. It becomes. Thereby, it becomes possible to reduce the damage which generate | occur | produces in a vehicle, the annular member 10, and the spacer part 18. FIG.

Also, as described above, unlike the case where the vehicle collides head-on with the bollard 1, when the impact is in the tangential direction of the covering member component, that is, when the vehicle collides with the bollard 1, the bollard 1 The state is as follows.
When the vehicle collides with the bollard 1 by offset, the portion of the covering member constituting portion 14 where the vehicle has contacted and collided is deformed into the gap portion 22.
At this time, the inner diameter dimension of the spacer portion 18 is set to be less than the inner diameter dimension of the covering member constituting portion 14, and the material of the spacer portion 18 is made of a metal having higher rigidity than the elastic material that is the material of the covering member constituting portion 14. As material.

For this reason, when an impact is applied to the covering member constituting part 14 from the outside, the spacer 18 comes into contact with the pillar member 2 before the covering member constituting part 14 comes into contact with the pillar member 2. The covering member constituting portion 14 that has contacted or collided rotates in the circumferential direction.
Therefore, the deformation of the covering member constituting portion 14 can absorb and reduce the impact applied by the vehicle to the covering member constituting portion 14, and the relative movement between the covering member constituting portion 14 and the column member 2 can reduce the vehicle. It is possible to absorb and reduce the impact applied to the covering member component 14.

(Coating member component replacement method)
As described above, when only a part of the covering member constituent portions 14 with which the vehicle has contacted or collided are damaged among the covering member constituent portions 14 when the vehicle contacts or collides with the bollard 1, The operation | work which replaces only the damaged covering member structure part 14 among the member structure parts 14 is performed. The work procedure will be described below.

Remove from the column member 2.

  Then, instead of the damaged covering member constituting portion 14, an unused covering member constituting portion 14 is attached to the column member 2. At this time, the penetrating portion 38 is disposed in the gap 22 provided in the unused covering member constituting portion 14, and the covering member constituting portion 14 adjacent to the unused covering member constituting portion 14 is provided, and the unused covering is provided. The penetrating portion 38 is also disposed in the gap portion 22 that overlaps the gap portion 22 included in the member constituting portion 14 in the vertical direction. Furthermore, the penetration part 38 arrange | positioned in the two space | gap part 22 which overlaps with an up-down direction is made to contact in the state which each opposed to the inner surface of the two space | gap part 22 along the circumferential direction of the coating | coated member structure part 14. FIG.

After the unused covering member constituting portion 14 is attached to the pillar member 2, the covering member constituting portion 14 laminated between the unused covering member constituting portion 14 and the arrangement between these covering member constituting portions 14 The seat 18 and the annular member 10 are also attached to the column member 2.
