Detailed Description of the Invention

[0001]

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 stop piece is rotatably provided, and a rotation shaft integrated with the stop piece is supported substantially horizontally at a position above the road surface in 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 via the notch hole on the side surface of the pillar main body, for unlocking from the outside. The locking is released by rotating the locking piece with the key via the rotation shaft.

Further, preferably, the rotation range of the locking piece is from the locking state by its own weight to the unlocking state in which the locking piece comes into contact with the inner surface facing the notch hole of the strut body.
Also, preferably, both ends of the rotation shaft of the locking piece are rotatably supported by a support tool rotatably mounted on the side surface of the column main body, and the end surface is covered, and the support tool is rotated from the side surface side of the column main body. A key insertion hole reaching the end face of the moving shaft is provided, and a key insertion hole is provided on the end face of the rotating shaft.

[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 pivoting shaft is rotationally operated from the outside by the unlocking key to pivot the locking piece, and the locking is released.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. In the drawings, reference numeral 1 denotes a buried cylinder, which is buried substantially vertically under the road surface. The embedded cylinder 1 is usually a bottomed cylinder having a circular cross section, a square shape, or the like, and is provided with a flange at the upper end. A locking hole portion 11 is provided on the side surface of the upper end portion of the embedded cylinder 1. This locking hole portion 11
Normally, as shown in FIG. 1, a cutout hole 12 is provided on the side surface of the embedded cylinder 1 and a case 13 is formed so as to cover the cutout hole 12 in a protruding manner. It suffices if the stopper 32 can be locked.

Reference numeral 2 is a main body of a column, the lower part of which is removably inserted into the embedded cylindrical body 1. The pillar main body 2 is usually made of a metal and has a circular cross section, a rectangular shape, or the like, and a notch hole 21 is provided in the side surface corresponding to the locking hole portion 11 of the embedded cylinder 1. A locking piece 3 is rotatably supported in the pillar main body 2 to prevent the locking piece 3 from coming off the embedded cylindrical body 1.

The locking piece 3 is made of metal, and a rotary shaft 31 is integrated at the upper end thereof. The rotary shaft 31 is offset to one side from the central axis of the pillar main body 2 and the road surface inside the pillar main body 2 is formed. It is supported in a substantially horizontal position at a higher position and is rotatable. As shown in FIG. 1, the locking piece 3 has its hook-shaped locking portion 32 at one end always inserted into the locking hole portion 11 of the embedded cylindrical body 1 through the notch hole 21 of the column body 2 by its own weight. It is designed to be locked. Further, the locking piece 3 can be rotated by externally rotating the rotation shaft 31 with the unlocking key 5 to release the locking.

Specifically, both ends of the rotary shaft 31 of the locking piece 3 are supported by the support tool 4 mounted on the side surface of the column main body 2. The support 4 has a bottomed tubular shape, and as shown in FIG. 2, the support 4 is inserted at a substantially right angle to the side surface of the column main body 2 with its bottom portion facing outward, and is rotatably mounted so as not to come off with a retaining ring or the like. The end of the rotary shaft 31 is rotatably inserted into the support 4 so that the end face is covered. Further, the support tool 4 is provided with a key insertion hole 41 reaching the end surface of the rotating shaft 31 from the side surface side of the column body 2, while the key inserting hole 33 is provided in the end surface of the rotating shaft 31 from the outside. The unlocking key 5 is inserted into the key insertion holes 41 and 33 so that the pivot shaft 31 is rotated together with the support tool 4.

In the above case, the rotating shaft 31 of the locking piece 3
Is rotatably supported with respect to the support 4, both the key insertion holes 41 and 33 are aligned, and the rotation key 3 is rotated by the unlocking key 5.
1 is rotated, but the rotation shaft 31 is previously fixed to the support tool 4 so as not to rotate, and the unlocking key 5 is inserted into the key insertion hole 41 of the support tool 4.
The rotary shaft 31 may be rotated together with the support tool 4 by inserting the.

In the pillar body 2, the locking piece 3 is pivoted and released from the state in which the locking portion 32 is locked in the locking hole portion 11 of the embedded cylindrical body 1 by its own weight. It may have any shape or size that can be in a state. Normally, as shown in FIG. 1, the locking piece 3 is locked by its own weight, and
It is rotatable up to the unlocked state (shown by the chain double-dashed line) in which it abuts the inner surface facing the notch hole 21, and the rotation range is restricted.

[0016]

As described above in detail, in the prop of the present invention, such as a car stop, the locking piece is rotatably supported by the turning shaft in the main body of the prop, and the locking part is moved from the road surface by its own weight. At the lower position, it is locked to the locking hole of the embedded cylinder through the notch hole on the side surface of the pillar body, and the locking piece is rotated from the outside by the unlocking key via the rotation shaft. Since the locking is released by the above, the retaining mechanism of the column main body does not project to the outside, and it is safe for pedestrians and the like and does not spoil the appearance. Moreover, the retaining mechanism is simple, easy to assemble, and hard to break down,
In addition to being cheap in terms of cost, it is easy to prevent the pillar body from coming off and to release it.

Further, since the rotation range of the locking piece is from the locked state by its own weight to the unlocked state in which it abuts against the inner surface facing the notch hole of the strut body, it is dependent on transportation and construction. The stop piece does not rotate more than necessary and troubles due to the rotation of the locking piece can be prevented, making it easy to handle.

Further, both ends of the rotation shaft of the locking piece are rotatably supported by a supporting member rotatably mounted on the side surface of the supporting column body, and the end surface is covered with the supporting member from the side surface side of the supporting column body. A key insertion hole reaching the end face of the rotation shaft is provided,
Since the key insertion hole is provided on the end face of the rotating shaft, the key insertion hole has a double structure, and it is difficult for a general person to understand the unlocking operation, and it is possible to prevent the pillar body from being stolen. Moreover, since both ends of the rotating shaft are supported by the supporting members mounted on the side surfaces of the supporting column main body, even if the diameter of the supporting column main body is changed, it is possible to easily cope with it by changing the length of the rotating shaft.
