This car stop has a structure suitable for vertically moving the lifting pole up and down. On the other hand, the upper end of the lifting pole pops out of the case when the lifting pole is fully retracted. Immersion descent, that is, a phenomenon in which the immersion cannot be made flush with the ground surface, may occur, which is a practical problem of this car stop.

Further, when a geared wire is used to operate the lifting means, the gear teeth spirally wound around the surface of the geared wire are chipped, which makes it difficult to apply a rotational force to the lifting means. This is also a problem in practical use of this bollard.

Another object of the present invention is to provide a device for preventing jumping up and down poles of a car stop that can prevent the gear teeth from being damaged even when the geared wire is used.

[0007]

[Means for solving the problems] Then, when the cause of the protrusion of the lifting pole and the cause of the gear tooth loss when using a geared wire were investigated, both of these were raised and lowered when the lifting and lowering of the lifting pole was completed. While the operation of the means is completed, the reaction force acts on the elevating means due to the inertia of the elevating pole and the collision with the bottom wall of the case, and this actuates the elevating pole in a slight upward direction. The protrusion of the elevating pole is caused by the operation allowance in the ascending direction, and the gear tooth loss when the geared wire is used is stopped by the operation allowance of the elevating means in the ascending direction. It turned out that it was because of the unreasonable force that tried to move it back and forth.

The present invention has been made on the basis of such knowledge, and by preventing the reaction force of the elevating pole, particularly the elevating means at the time of immersing and lowering, the protrusion of the elevating pole and the gear when a geared wire is used. In order to prevent tooth loss, a shock absorber that absorbs the above reaction force in a buffer manner is provided in the connection between the elevating means and the elevating pole, and this structure is commonly provided. That is, according to the present invention, the lifting pole housed in the case for underground embedding according to claim 1 is installed in the case and is connected to the lifting pole by a rotating chain, a push-pull chain, a winding wire, or the like.
