DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle stop using a traveling device having a rail and a pedestal traveling on the rail, and is used for traffic regulation in a public plaza.

[0002]

2. Description of the Related Art It is well known that a vehicle is provided with a traveling device that causes a pedestal to travel on rails at a vehicle stop or the like. For example, Japanese Unexamined Patent Publication No. 9-88025 describes a slide pole bollard in which a rail, a plurality of pedestals, and poles are erected on each pedestal and the plurality of pedestals are guided so as to be able to run on the same rail. . However, in order to keep each pole stable and upright, the rail on which the pedestal runs is parallel to two.
The pedestal has a complicated structure having lateral rollers for preventing overturning on both left and right sides of the pedestal in order to withstand the lateral load received by the pole. Further, in order to mount the pedestal on the rail, it is necessary to form a cutout for inserting a horizontal roller in a part of the rail in advance, or to insert the cutout from a small edge at the end of the rail. For this reason, when installing the rail, it is necessary to consider the installation location, the position where the roller is mounted, and the like.

Japanese Utility Model Laid-Open Publication No. 63-46593 discloses a curtain-type gate in which a sliding door is movably mounted on an attached rail. Since the rails are arranged in two parallel lines for stabilization, it is difficult to reduce the rail width.

A pole is erected on each pedestal to form a bollard . The rail has a fin that protrudes left and right at the top in the cross section,
The pedestal has a main body (fixed portion) made of a casting or the like, and has an upper rolling wheel and a lower rolling wheel. The pedestal is mounted on the rail such that the upper rolling wheel is disposed on the upper surface of the rail and the lower rolling wheel is disposed below the fin portion of the rail, and the fin portion of the rail is sandwiched from above and below. The upper and lower rolling wheels are:
Iron rings are common, but they are sometimes made of synthetic resin or hard rubber to suppress noise. The pedestal may be configured to include an upper rolling wheel as a front wheel and a rear wheel in a traveling direction and a lower rolling wheel as an intermediate wheel. The front wheel, the rear wheel, and the intermediate wheel have an inverted triangular arrangement with the rail interposed therebetween in a side view.

It is preferable to employ the following configuration. The lower rolling wheel is detachable from the base. The lower rolling wheel is supported by a lower portion of the support member, and the support member is detachably attached to a side surface of the pedestal by screwing or the like. In this case, if a groove for fitting the upper part of the support member is provided in the center of the side surface of the pedestal, for example, even if the support member is fixed with one screw, the support member is prevented from swinging and securely fixed. Can be. The pedestal and the pole constitute a moving pole and the whole is a car stop.
There are a plurality of moving poles in a bollard, and thus a plurality of pedestals run on a single rail, and in addition, the moving poles may be connected by a rope, a rope chain, or another cable. In practice, the pole is mainly made of a stainless steel pipe, a synthetic resin pipe or a cast pillar.
