2. Description of the Related Art There has been proposed a bollard in which a plurality of moving poles are arranged on a rail, and the moving poles are connected by a rope such as a rope chain.

Japanese Patent Application Laid-Open No. 9-88025 describes a slide-type pole in which a plurality of pedestals are movably arranged on a rail, and poles are erected on each pedestal. Since this device uses two rails and the bogie is relatively large, the pole can be moved stably, but no mechanism can be found to assist the movement when the pole is moved.
In addition, as long as the rope between the poles is not taut, it is necessary to adjust the positions of the moving poles in order to arrange the moving poles at equal intervals. Japanese Utility Model Laid-Open Publication No. 1-150624 describes a traffic divider moving device provided with a driving device for arranging a plurality of poles on a deep groove-shaped guide frame and moving the poles to a deployed position or a storage position. ing.
However, this driving device is a large-scale auxiliary device that assists in moving the moving pole.

[0004] Japanese Utility Model Laid-Open No. 1-98220 discloses that a plurality of poles are pivotally mounted on a grooved rail and provided so as to be movable up and down in the rail direction. Are raised and erected at once, and then loosened to collectively fall into the groove of the rail, but the operation of tensioning and loosening the rope becomes considerably heavy. Further, since the groove-shaped rail for accommodating the pole is opened upward, a lid member is required so as not to be dangerous.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a car stop which can easily move a plurality of moving poles to a storage position and arrange the moving poles at equal intervals.

SUMMARY OF THE INVENTION A rail and a plurality of moving poles running on the rail are provided. The rails are fixed in cast concrete grooves, etc., and each moving pole consists of a pedestal running on the rail and a pole standing upright. A rope such as a rope chain is hung between adjacent poles. This rope has a normal weight like a rope chain, and the horizontal component of the load applied to the moving pole by the weight is larger than the running resistance of the moving pole. It should be noted that the pedestal that travels on the rail is provided with a lock mechanism such as a brake at least at the leading end in the pullout direction, and can maintain the stop position on the rail.

When the weight of the rope is insufficient, a weight is attached to the rope so that the horizontal component of the load applied to the moving pole together with the rope becomes larger than the running resistance of the moving pole. In this sense, the cable may be an ordinary rope, wire or string. The weight may be a sign-like member having a reflector attached thereto, or a decorative member considering the design. In addition, if the length of the rope between the adjacent moving poles is less than twice the length from the mounting position to the moving pole to the ground, even if the distance between the moving poles becomes small, the hanging rope contacts the ground. Therefore, the horizontal component of the load applied from the cable to the moving pole can be effectively used to the end.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A bogie 1 (FIG. 1) includes a rail 2 laid at an exit portion, a plurality of moving poles 3 guided and guided by the rail 2, and a rope chain 4 connecting the moving poles 3 with each other. Equipped, each moving pole 3 is a rail 2
The pedestal 5 is guided so as to be able to travel and a pole 6 erected on the pedestal 5. The rail 2 is a single rail, and is fixed to a groove 8 of concrete 7 which is cast so that the upper surface is substantially the same height as the ground. The pedestal 5 (FIG. 2) is made of a cast material or the like, and supports the front wheel 9 at the front in the running direction at the left and right of the shaft 10 and the rear wheel 11 at the rear at the left and right of the shaft 12 in the running direction. ing. Further, an intermediate wheel 13 is supported by a shaft 14 below the front wheel 9 and the rear wheel 11 and provided on both sides of the rail 2. The front wheel 9, the rear wheel 11, and the intermediate wheel 13 are usually iron wheels, but may be formed of synthetic resin or hard rubber to suppress noise. Note that the front and rear directions are for convenience of description and may be interchanged.

The front wheel 9, the rear wheel 11 and the intermediate wheel 13 are arranged in an inverted triangle, and extend between the upper front wheel 9, the rear wheel 11 and the lower intermediate wheel 13 to the left and right of the rail 2. The fin portion 15 is sandwiched. When the pedestal 5 runs,
The front wheel 9 and the rear wheel 11 support the load of the moving pole 3, prevent the pole 6 from falling down in the front-rear direction, and engage the intermediate wheel 13 with the lower surface of the fin 15, so that the pedestal 5 is lifted. Prevents the pole 6 from falling left and right. Thereby, the pedestal 5 runs on the rail 2 lightly and stably.

Further, the pedestal 5 has an eccentric cam 17 (FIG. 3) integral with the operation lever 16 on the front shaft 10, and constitutes a lock mechanism. At the rear of the pedestal 5, there is provided a release portion 19 in which a part of the pedestal has an inclined surface 18. That is, when the moving pole 3 is pulled out of the storage location and the operation lever 16 is depressed at an arbitrary position, the eccentric cam 17 rotates to act to push the pedestal 5 up against the rail 2,
The fin portion 15 is engaged with the lower intermediate wheel 13, and the movement of the pedestal 5 is prevented by frictional resistance. Moving pole 3
When storing, release the lock and move to the storage side. At this time, even if another moving pole 3 adjacent to the moving direction is in the locked state, if the pedestal 5 of the moving pole collides, the rear part of the pedestal 5 (in this case, the front in the direction of moving in the storage direction). The operation lever 16 is pivoted upward by the inclined surface 18 and the locked state is released. Even if there are a plurality of moving poles 3 in the locked state, the lock can be sequentially released in this manner. That is, by simply pushing the movable pole 3 at the end toward the storage side, the other movable poles 3 can be automatically unlocked and stored.

The pole 6 is mainly composed of a stainless steel pipe, a synthetic resin pipe or a cast pillar, and has a base fixed to the upper surface of the pedestal 5. The rope chain 4 is an example of a rope connecting the poles 6 and is used to utilize the weight of the chain itself. Weight W of rope chain 4
(FIG. 4) acts on the vertex P of the natural sagging curve, ie at the intermediate position between the two poles 6, and the rope chain 4
Q1 and Q2 points connecting both ends of
Assuming that the angle between the line connecting 1 and the point P and the vertical axis of the pole 6 is α, it is considered that a load of approximately F1 = W / 2 · cos α acts in the directions of the lines P · Q1 and P · Q2. be able to.

The load F1 is composed of a vertical F2 supported by the pole 6 and a horizontal component F3 = F1 · sin α.
The horizontal component force F3 is a force for moving the moving pole 3 along the rail 2. That is, the weight W of the rope chain 4 is F1 = W / 2 · si
The force for moving the moving pole 3 is nα · cosα.
Therefore, if the force F3 is greater than the running resistance f0 of the pedestal 5, the moving pole 3 starts running naturally due to the weight of the rope chain 4. However, as the distance between the poles 6 decreases, the horizontal component force F3 rapidly decreases. The force F3 is the running resistance f0 of the pedestal 5.
When it becomes smaller, the moving pole 3 does not move or stops moving halfway. However, at this time, even if the moving pole 3 is pushed by hand, the operation is lightened by the force F3. As described above, when the horizontal component F3 of the load that the rope chain 4 applies to the moving pole 3 is used to the end even if the value is small, the rope chain 4 is attached to the moving pole 3 from the mounting position Q1 to the ground. Is preferably not more than twice the distance. In this way, even if the interval between the moving poles 3 becomes small, the hanging rope chain 4 does not come into contact with the ground, and the horizontal component force F3 can be effectively used at the end.

When the weight 20 is provided on the rope chain 4 between the moving poles 3, the weight W increases, so that the horizontal component force F 3 also increases, thereby coping with a larger running resistance of the pedestal 5. Can be. Further, such a weight 20 is not merely for increasing the weight, but also attaches a reflector or a danger sign to call attention to the presence of the wheelchair 1, or as a decorative appearance, which is often a feeling of alienation. It can soften the atmosphere of a certain car stop.

By the way, the traveling resistance of the traveling pole 3 (850 mm, 3.0 kg) shown in FIG. 1 was measured by pulling the spring scale connected to the center of the pole 6 horizontally. When moving one moving pole 3 alone 0.15 kg at starting, 0.1 k after starting running
g, and the length of the rope chain 4 (1000 mm in length, 0.
When the four moving poles 3 connected at 6 kg were to be pulled out, the maximum was 0.1 kg at the time of starting and 0.5 kg at the maximum when all of the four moving poles 3 were driven simultaneously. From this, it is appropriate that the weight of the rope chain 4 including the weight 20 is 1 to 3 kg.

According to this configuration, when the movable bollard 1 is stored and the moving pole 3 is unlocked, the moving pole 3 is biased in the storing direction by the horizontal component force of the load applied by the rope chain 4. Receiving and moving in the storage direction. When there are a plurality of movable poles 3, all the movable poles 3 start moving by releasing the lock of the movable pole 3 closest to the drawing side, and can be quickly stored. This is particularly effective when the storage direction is uphill. Further, when a plurality of movable poles 3 are pulled out from the storage position and deployed, if only the movable pole 3 closest to the pull-out side is pulled out, the others are connected to the rope chain 4 and pulled out. Since the horizontal component force is determined by the distance between the moving poles 3, if the weight of the rope chain 4 between the adjacent moving poles 3 is equal, or if the weight of the rope chain 4 including the weight 20 is equal, the moving pole The interval between the three has a tendency to be automatically determined, and it is easy to deploy the moving pole of the car stop 1 at a fixed position.

[0015]

According to the structure of the first and second aspects of the present invention, the movable pawls of the deployed vehicle stop can be stored lightly and quickly. In particular, this is effective when the storage direction is an upward slope. Further, when deploying the moving poles, it is easy to arrange the moving poles at equal intervals. According to the configuration of claim 3,
It can enhance the function as a car stop and improve the design. According to the configuration described in claim 4, when the bogie is in the stowed state, the hanging portion of the rope does not reach the ground until the moving pole reaches the storage position. The horizontal component of the load applied to the moving pole can be used to the end.
