BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prop for a car stop or the like installed on a road surface as a road stop for vehicles.

[0002]

2. Description of the Related Art Conventionally, as a pillar for a car stop or the like, as described in, for example, Japanese Utility Model Publication No. 61-3932, a lower part of a columnar body is detachably attached to an embedded cylindrical body which is buried substantially vertically under a road surface. By inserting a pin through the lid that is inserted and pivotally attached to the upper end of the embedded tubular body so as to be openable and closable, the pin penetrates slightly above the road surface of the columnar body, and the padlock is locked at the through end. It is known that the columnar body is prevented from coming off or being stolen.

Further, as described in Japanese Utility Model Publication No. 4-49221, there is also known a fence fixing device in which a leg of a fence is detachably inserted into a pipe which is buried substantially vertically under the road surface. In this fence fixing device, a dogleg-shaped arm is rotatably supported in a tubular leg portion, and an upper end portion of the arm is projected from an upper cutout hole on a side surface of the leg portion. The lock pin is inserted into the bracket protruding from the lock pin and the padlock is locked on the lock pin, so that the arm lower end hook part is locked to the hook part of the pipe through the lower cutout hole on the side surface of the leg part. When the lock pin is removed, the arm rotates by its own weight to release the lock.

[0004]

However, in the former case, the lid, the pin, and the padlock, which form the mechanism for preventing the columnar body from coming off, are projected to the outside of the columnar body, so that a pedestrian or the like pulls his / her foot on it. There is a problem that it is dangerous to wear and it is inferior in aesthetics. Moreover, the insertion of the columnar body into the embedded cylindrical body does not prevent the pin from coming off, and the pin must be penetrated into the columnar body to be locked with a padlock, which is a troublesome operation for retaining.

Also in the latter case, a part of the retaining mechanism for the legs of the fence, that is, the upper end of the arm, the bracket of the legs,
Since the lock pin and the padlock are projected to the outside of the legs, they are dangerous to pedestrians and the like as in the former case, and there is a problem that the appearance is poor. In addition to the arm, a bracket, a lock pin, and a padlock are required as a retaining mechanism, and there are many members, and there is a problem that the structure is not yet simplified. In addition, simply inserting the legs of the fence into the pipe will not prevent it from coming off.You must rotate the arm to insert the lock pin into the upper end of the arm and the bracket, and lock the padlock. However, there is a troublesome problem.

An object of the present invention is to provide a column such as a car stop that solves the conventional problems.

[0007]

In order to solve the above problems, the present invention provides a locking piece rotatably provided in a column main body,
Due to its own weight, the locking piece is locked to the embedded cylinder to prevent it from coming off. That is, the prop of the present invention, such as a car stop, has a cylindrical prop body whose bottom portion is removably inserted into an embedded cylinder body that is buried substantially vertically under the road surface. A stopper is rotatably provided, and the upper end of the stopper is pivotally supported by a holder fixed to an inner surface on one side above the road surface of the pillar body.
Due to the weight of the locking piece, the hook-shaped locking part at one end is locked at the position below the road surface in the locking hole part of the embedded cylinder through the notch hole on the side surface of the pillar main body, and is retained on the road surface. The lock is released by inserting an unlocking key from the outside into a key insertion small hole provided on one side surface of the strut body between the tools and pressing and rotating the locking piece. It was made.

Further, preferably, the holder is provided with a restricting piece facing the inner surface of the support column at a predetermined interval, and from the locking state of the locking piece to the unlocked state of abutting against the restricting piece of the holder. It is made rotatable between the two.

[0009]

When the lower part of the pillar main body is inserted into the embedded cylinder, the locking portion of the locking piece protruding from the notch hole on the side surface of the pillar main body is pressed into the pillar main body by the upper end of the embedded cylinder and the locking piece is inserted. When the pillar is rotated and the pillar body is inserted to a predetermined position, the locking piece is rotated by its own weight so that the locking portion engages with the locking hole portion of the embedded cylinder through the notch hole on the side surface of the pillar body. It will be stopped and will not come off. Further, when the pillar body is removed, the unlocking key is inserted from the outside into the key insertion small hole, and the locking piece is pressed and rotated by the tip of the key to release the locking.
