The locking device 4 comprises a locking piece 5 and a locking mechanism for converting the locking piece 5 between a hanging position and an inclined position. This locking piece 5 has a locking claw 6 formed at its lower end,
The upper end is externally fitted to a small-diameter projection 8 formed at the end of the rotary shaft 7 and fixed to the end.

The rotary shaft 7 is held by a mounting plate 10 fixed to the lower portion of the car stop support column 1. That is, a holding cylinder 11 is fixed to the mounting plate 10 at a position directly above the linking rod 26 in a radial direction parallel to the linking rod 26, and the holding cylinder 1
A rotary shaft 7 is rotatably inserted in the shaft 1. And
The small-diameter projection 8 at the tip is projected inward, and the locking piece 5 is externally fitted to the small-diameter projection 8 as described above.
Is in contact with the front end of the holding cylinder 11.

Further, a key groove 9 is formed on the other end surface of the rotary shaft 7, and the key groove 9 is exposed to the outside from an operation hole 12 formed on the side surface of the car stop strut 1.

Furthermore, the mounting plate 11 is bent at its central portion to vertically hang a hanging piece 13 so as to face the inner end of the holding cylinder 11, and the hanging piece 13 has a small diameter of the rotary shaft 7. It supports a protruding piece 14 whose tip lightly contacts the protruding portion 8.
The projection piece 14 is formed of a bolt in the embodiment. Further, the seat plate 15 is externally fitted to the small-diameter projection 8 of the rotary shaft 7 so as to come into contact with the upper end of the locking piece 5.
The spring 16 is interposed between the hanging pieces 11 to elastically hold the locking piece 5 at a position where it abuts on the front end of the holding cylinder 11. That is, the protrusion 14 restrains the inward movement of the rotary shaft 7, and the bar 16 holds the locking piece 5 in a position where it abuts the holding cylinder 11.
The rotation of the can be smoothly performed without rattling.
Thus, the rotation shaft 7 or the like constitutes a locking mechanism for converting the locking piece 5 between the hanging position and the inclined position.

On the other hand, as shown in FIG. 5, the holding cylinder 1
In FIG. 1, two holding holes 17a, 17b for defining a turning angle between the hanging position and the tilt position of the locking piece 5 are formed in correspondence with the turning angle, and the fitting insertion formed on the rotary shaft 7 is further performed. A ridge 19 and a moderating sphere 20 biased outward by the ridge 19 are mounted in the hole 18, and the moderating sphere 20 is sequentially moved to a holding hole 17a and a holding hole 17b by rotating the rotary shaft 7. 3 at the position where the moderating ball 20 is fitted into the holding hole 17a, and the locking piece 5 is in the hanging position of the chain line in FIG. 3, and the moderating ball 20 is fitted into the holding hole 17b. I am trying to become. Thus, the moderation action of the spring 19 prevents the rotation shaft 7 from moving in a delusional manner.
Will be stably held in the two positions described above.

Further, a key groove 9 is formed on an end surface of the rotary shaft 7 exposed from the operation hole 12, and the key shaft 9 is formed on the rotary shaft 7.
Also, in order to rotate the locking piece 5, it is necessary to insert a dedicated operation key 22 that matches the key groove 9 and rotate it. Depending on a user who does not carry the operation key 22, the locking piece may be locked. It becomes impossible to set 5 as the storage position.

On the other hand, the locking piece 5 is provided on the lower peripheral surface of the car stop column 1 at a position facing the locking claw 6 of the locking piece 5.
A through hole 25 into which the locking claw 6 is inserted is formed at the inclined position. The linking rod 26 is radially extended in the direction orthogonal to the tilting direction of the locking piece 5, and the projecting end thereof serves as the locking projections 3 and 3. Therefore, the through hole 25 has the locking projections 3 and 3. It is arranged at a relative angular position of 90 degrees with respect to 3.

Next, the structure of the mouth cylinder 30 will be described. The mouth cylinder 30 is fitted in the mouth of the base cylinder 40, and as shown in FIG. 7, locking grooves 31, 31 opening downward are formed in a point symmetry on the peripheral surface thereof. ing. The locking grooves 31, 31 are for receiving locking projections 3, 3 penetrating the car stop column 1 of the locking piece 5 and projecting outward from the lower end opening, and a guide extending upward from the lower end opening. Ditch 32
And a hook-shaped linking groove portion 3 continuous with the top of the guide groove 32.
3 and 3 are created.

The guide groove 32 has a shape in which the skirt extends up to an angular width of 180 degrees and rises in a mountain shape, and a hem portion which is an opening edge thereof serves as an introduction edge 34. Therefore, as will be described later, the car stop support column 1 housed in the base tubular body 40.
When the lever is pulled out, the locking projections 3 are introduced into the guide groove 32 together with the leading edge 34 by the guiding action of the lead-in edge 34.

On the other hand, the linking groove 33 is formed in the mouth cylinder 30.
A locking hole 35 is formed at a relative angular position of 90 degrees. The locking hole 35 is located at a position where the locking projections 3 are located inside the linking groove 33 and faces the through hole 25.

Next, the operation of this structure will be described.

In the state in which the car stop strut 1 is removed from the road surface, it is in a housed state in which it is built in the base tubular body 40 shown in FIG. In this state, the car stop support 1 is attached to the base cylinder 4
When it is pulled out from inside 0, as shown in FIG.
3 abuts on the introduction edge 34 formed at the lower end of the guide groove 32 (a), the car stop strut 1 is slightly rotated by its guiding action, and the locking projections 3 are introduced into the guide groove 32. It
Then, at the position (b) where the locking projections 3, 3 come to the top end of the guide groove 32, the car stop support post 1 cannot be pulled out. Then, the car stop strut 1 is slightly rotated laterally to be positioned in the hook-shaped linking groove portion 33, and the moving operation of the car stop strut 1 is completed. At this position (c), the load of the car stop column 1 is supported by the bottom edge of the linking groove 33, and the through hole 25 and the locking projections 3, 3.
3 will match.

Next, the operation hole 1 on the side surface of the base of the car stop strut 1
The operation key 22 is inserted into the key groove 8 of the rotary shaft 7 exposed from 2, and the rotary shaft 7 and the locking piece 5 are rotated. As a result, the moderating sphere 20 escapes from the retaining hole 17a against the spring 19, and when the locking piece 5 reaches the inclined position of the solid line in FIG. Is retained. At this inclined position, the locking claw 6 of the locking piece 5
Is inserted into the locking hole 35 from the through hole 25. As a result, the locking piece 5 becomes immovable and is in a locked state, and the linking groove 33 holds the position where the locking projections 3, 3 are supported. Then, in this state, even if an attempt is made to lift the car stop strut 1, the car stop strut 1 becomes immovable, and the car stop strut 1 is held in the standing position in FIG. Will be fulfilled.

Next, when the car stop strut 1 is set to the storage position shown in FIG. 2, the operation hole 12 is formed on the side surface of the base of the car stop strut 1.
The operation key 22 is again inserted into the key groove 9 of the rotary shaft 7, the rotary shaft 7 and the locking piece 5 are rotated, and the moderating ball 20 is fitted into the holding hole 17a and held at the hanging position of the chain line in FIG.
As a result, it is unlocked, and the car stop column 1 is slightly floated and slightly rotated backward, so that the locking projections 3 are released from the inside of the linking groove portion 33 to the top end position of the guide groove passage 32. As a result, the car stop strut 1 loses its support and falls into the base tubular body 40 by its own weight, and the locking protrusions 3 and 3 are disengaged downward from the locking grooves 31 and 31. The storage position is shown in FIG. 2, which is built in the base tubular body 40.

In the above-described embodiment, the mouth cylinder 3 in which the locking grooves 31, 31 and the locking hole 35 are fitted in the mouth of the base cylinder 40.
Although it is formed at 0, it may be directly formed at the mouth of the base tubular body 40.

[0029]

As described above, according to the present invention, the locking device is provided with the locking projection having the locking projection formed on the lower end of the car stop column and having the locking claw formed therein. To form the locking groove and the locking hole on the inner peripheral surface of the mouth of the body and to set the car stop strut to the standing position, the locking projection of the car stop strut is positioned in the locking groove to make it impossible to move up and down. At the position, lock operation is performed from the operation hole formed on the side of the car stop strut so that the locking piece is in the inclined position and the locking claw is inserted into the locking hole at the mouth of the base tube through the through hole. As a result, unless the locking piece is moved to the hanging position by the next unlocking operation, the car stop strut cannot be rotated and the car stop strut can be stably secured in the standing position. For this reason, since there are no protrusions on the circumferential surface of the car stop strut, it is possible to easily form the car stop strut in a form that can enhance the design feeling, ensure the safety of traffic, and open the car stop strut. Does not require an unlocking operation by a key operation, so that an unnecessary person does not remove the car stop strut to the storage position, and it has an excellent effect that the car stop strut can be reliably and easily maintained and managed.
