DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pole which is installed to prevent a person or a vehicle from freely entering or leaving private property or the like. About Paul.

[0002]

2. Description of the Related Art In order to prevent people and vehicles from entering at the entrance of a parking lot only during the night, a chain is suspended over a plurality of poles that can be inserted and removed from the ground. Wheel stops are often used. These bollards
Although it could be installed and removed, it was quite difficult to carry out one pole at a time. Therefore, a configuration in which a pole slides on a rail laid on the ground as shown in Japanese Patent Application Laid-Open No. 9-88025 has been considered.

[0003]

When such a slide type pole is installed in the frontage where the ground is inclined, the pole is fixed vertically to the bogie guided by the rail.
Paul was leaning against the ground. The present invention
An object of the present invention is to provide a sloping pole for a sloping ground, which can stand the pole vertically even in a sloping place.

[0004]

According to a first aspect of the present invention, there is provided a slide pole including a rail, a truck running on the rail, and a pole standing on the truck. The pole is pivotally connected with the horizontal connecting shaft, and the pole has a push bolt whose tip abuts on the upper surface of the bogie on both sides of the connecting shaft,
The pole is fixed at an arbitrary angle by moving the push bolt forward and backward.

[0005] It is considered that the pole is often implemented in a form that can swing back and forth along the traveling direction of the bogie. However, it is not limited to this form. The pole may be swingable in a direction perpendicular to the traveling direction of the bogie.

As described in claim 2, when the pole and the bogie are connected by a ball joint, the angle of the pole can be adjusted in all directions, front, rear, left and right.

In order to fix the angle of the pole, a vertical slit is provided on both sides of the axis of the connecting shaft of the pole, and a fixing tool is inserted into the slit to fix the slit and the carriage. It can also be performed by fixing with a tool. The fixing device may be any one that can be inserted into an arbitrary position of the slit, and may be one that locks into the slit after the insertion. For example, a special wedge-shaped metal fitting with a projection on the periphery may be used. Tapping screws can be used. The slit may have a long hole shape, and the slits on both sides may be penetrated and connected.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. The sliding pole according to the present invention,
As shown in FIG. 1 (a), it is composed of a rail 1 laid on an inclined ground and a plurality of moving poles 2 sliding on the rail 1. Each of the moving poles 2 is connected by a chain 10 so that a person or a car cannot enter unnecessarily. As shown in FIG. 1 (b), the sliding pole can easily open the frontage by sliding the moving pole 2 and moving it to one side of the rail 1. Moving pole 2
It is composed of a truck 3 guided by a rail 1 and a pole 4 erected on the truck 3, and the pole 4 can swing back and forth in the traveling direction of the truck 3, and can be fixed at an arbitrary angle. Each pole 4 stands upright despite the slope of the ground.

FIG. 2 is an enlarged view of the connecting portion of the bogie 3 and the pole 4 in FIG. 1, and FIG. 3 is a view of the same portion viewed from the traveling direction of the bogie 3. The truck 3 has four wheels 18 of front, rear, left and right engaging with edges on both sides of the upper surface of the rail 1,
The rail 1 runs on the intermediate wheel 20 that is attached to the middle of the front and rear wheels 18 via a detachable bracket 19 and rolls on the back side of the rail 1. Dolly 3
Can be fixed at an arbitrary position on the rail 1 by a brake device (not shown).

The pole 4 is formed by fitting a cap to the upper end of a hollow pipe 11 and fitting a joint member 12 to the lower end. The joint member 12 is a cover piece 1 that spreads in a trumpet shape downward.
3, and a prism-shaped connecting piece 14 protrudes at the center of the inside. A columnar connecting portion 15 is provided on the upper surface of the carriage 3, and the joint member 12 is provided on the upper surface of the connecting portion 15.
A bolt 6 is inserted through the connecting portion 15 and the connecting piece 14 in a direction perpendicular to the longitudinal direction of the rail 1 so as to penetrate the connecting portion 15 and the connecting piece 14. And are connected.

Since the female screw is cut in the hole through which the bolt 6 of the connecting piece 14 is passed, the angle of the pole 4 can be fixed temporarily by tightening the bolt 6, but the fixing strength alone is weak, so that the pole 4 is strong. The push bolt 5 is used to fix the push bolt 5. Two push bolts 5 are provided symmetrically on the upper surface of the joint member 12 on both sides of the axis of the bolt 6. The tip of the push bolt 5 is in contact with the upper surface of the connecting portion 15, and by adjusting the advance and retreat of the push bolt 5 on both sides, the angle of the pole 4 can be finely adjusted and fixed. The fixing strength is very strong because it depends on the buckling strength of the push bolt 5. The adjustment of the push bolt 5 is performed before the pipe 11 is attached to the joint member 12. Further, in the example shown here, the pole 4 can be adjusted back and forth in the same direction as the traveling direction of the bogie 3. The angle of 4 may be adjusted in a direction perpendicular to the traveling direction of the carriage 3.

The joint member 12 and the connecting portion 15 of the truck 3
As shown in FIG. 4, the ball joint 17 may be used. In this case, four push bolts 5 are provided dispersed around the ball joint 17. With this structure, the angle of the pole 4 can be arbitrarily adjusted and fixed in all directions of front, rear, left and right.

FIGS. 5A and 5B show still another embodiment of the connection structure between the joint member 12 and the bogie 3. The connection by one lateral bolt 6 is the same as that described above, but the means for fixing the angle of the pole 4 is different. Here, the connecting piece 14 of the joint member 12 is formed in a semicircular shape, and a hole through which the bolt 6 passes is formed at the center of the arc. In the center of the connecting piece 14 in the thickness direction, a vertical slit 7 is provided. Joint member 1
After the bolt 2 and the truck 3 are temporarily fixed, the tapping screws 8, 8 are screwed into the slit 7 from both sides through holes formed in the side surface of the connecting portion 15 of the truck 3,
The connecting portion 15 and the joint member 12 are integrated, and the angle of the pole 4 is firmly fixed. The width of the slit 7 is the same as the diameter of the tapping screw 8 at the bottom of the screw thread, and the tapping screw 8 can be screwed into the slit 7 at an arbitrary position while cutting a screw. Can be fixed easily. The slit 7 may be a long hole (in the embodiment of FIG. 5, a state where the lower ends of the connecting pieces 14 are connected).

[0014]

The slide pole according to the present invention has means for connecting the pole on a trolley in a swingable manner and having means for firmly fixing the pole at an arbitrary angle. But the pole can always be installed vertically. There are two types of means for fixing the angle of the pole: a means using a push bolt and a means for inserting a fixing tool into a slit provided in the pole to fix the pole. Can be easily installed. In particular, when a push bolt is used, the angle can be finely adjusted, and the verticality of the pole can be accurately obtained. Further, as described in claim 2, when the pole and the bogie are connected by a ball joint, the angle of the pole can be adjusted in all directions of front, rear, left and right.
