As a part of the body 1, an annular cap 4 having a female screw portion 41 on an inner peripheral surface is fixed to an upper end surface of the main body portion by a bolt. Further, the shaft 2 is provided at its upper end with the female screw portion 41.
And a male screw portion 21 that is screwed with the screw.

Hereinafter, each configuration will be described in detail. As shown in FIGS. 1 to 3, the body 1 is formed in a tubular shape, and an anchor bolt 16 for fixing the body 1 in the ground is protruded from an outer periphery of an intermediate portion thereof. . A spring receiving seat 11 and a shaft locking step 12 are sequentially provided on an inner peripheral upper portion of the body 1, and a rotation preventing locking projection 13 is further provided on the upper portion thereof. The locking projections 13 are formed at every 90-degree angle, and a portion between the locking projections 13 is a fitting portion 15 on which a locking projection 22 of the shaft 2 described later is located. A slope 14 is provided on the lower surface of the locking projection 13 (see FIG. 4).

The shaft 2 is inserted into the body 1 so as to be able to move up and down. A male screw portion 21 is engraved on the outer periphery of the upper end of the shaft 2. In addition, a handle engagement hole 23 for engaging with the projection 51 of the handle 5 is provided on the upper end surface of the shaft 2, and a locking projection 22 is provided on the outer periphery of the intermediate portion of the shaft 2 at every 90-degree angle. doing.

The spring 3 is interposed between the spring seat 11 of the body 1 and the locking projection 22 of the shaft 2,
Is urged upward.

On the other hand, the bollard support column 6 is formed in a tubular shape, and a female screw portion 61 to be screwed with the male screw portion 21 of the shaft 2 is provided inside a lower portion thereof.

Next, the operation of the support device will be described. In order to remove the brace post 6 from the support device from the state shown in FIG. 2, first, the brace support column 6 is screwed in the loosening direction. As a result, the screwed state between the male screw part 21 of the shaft 2 and the female screw part 61 of the vehicle stop strut 6 is released. Therefore, the bollard support 6 can be removed from the shaft 2.

Next, the protrusion 51 of the handle 5 is engaged with the handle engagement hole 23 of the shaft 2, and the shaft 2 is pushed downward. Thereby, the engagement state between the locking projection 13 of the body 1 and the locking projection 22 of the shaft 2 is released. When the shaft 2 is further pushed downward, the male screw portion 21 of the shaft 2 hits the female screw portion 41 of the cap 4. Then, the shaft 2 is screwed in the tightening direction by the handle 5. Thereby, as shown in FIG. 1, the male screw portion 21 of the shaft 2 and the female screw portion 41 of the cap 4 are screwed together, and the upper surface of the shaft 2 and the upper surface of the cap 4 eventually become flat.

Is screwed in the loosening direction. Thereby, the threaded state of the male screw part 21 of the shaft 2 and the female screw part 41 of the cap 4 is released.

When the screwed state is released, the urging force of the spring 3 interposed between the body 1 and the shaft 2 acts to raise the shaft 2. At this time, the locking projection 22 of the shaft 2 comes into contact with a slope 14 (see FIG. 4) provided on the lower surface of the locking projection 13 of the body 1, and the slope 14
Slide along. The locking projection 22 engages with the fitting portion 15 between the locking projections 13, 13. Thereby, the rotation of the shaft 2 is regulated. When the locking projection 22 engages with the fitting portion 15 as described above, the locking projection 22 comes into contact with the lower surface of the cap 4 fixed to the upper surface of the body 1, and the shaft 2 moves upward. Is regulated.

At this time, the shaft 2 is in a state where its upper part is projected from the body 1. Therefore, the female screw portion 61 of the vehicle stop support 6 is screwed to the male screw portion 21 of the shaft 2. At this time, the locking projection 22 is engaged with the locking projection 13 and cannot be rotated, so that the screwing operation can be performed without any trouble. Thus, the brace 6 is erected.
