Description

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 similar to a car stop, for example, as disclosed in Japanese Utility Model Publication No. 4-49221, a leg portion of a fence can be attached to and detached from a pipe which is buried almost vertically under a road surface. An inserted fence fixing device is known. 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.

[0003]

However, in such a fence fixing device, the arms in the legs are adapted to rotate to the unlocked state due to their own weight, so that the legs of the fence are simply inserted into the pipe. There is a problem in that the lock operation is troublesome because the lock cannot be prevented by itself, and the arm must be rotated to insert the lock pin into the upper end of the arm and the bracket and then the padlock must be locked. Moreover, as a retaining mechanism, in addition to the arm and padlock, it is necessary to project a bracket on the side of the leg and use a lock pin.
There is a problem that the number of members increases and the structure is not yet simplified.

It is an object of the present invention to provide a strut such as a car stop that solves the above conventional problems.

[0005]

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.
The hook-shaped locking portion at one end is locked by the dead weight of the locking piece at a position lower than the road surface in the locking hole portion of the embedded cylinder through the lower cutout hole on the side surface of the pillar main body one side, and
An operation protrusion protruding from one side of the locking piece is protruded from an upper cutout hole on the side surface of the strut main body between the road surface and the retainer, and a padlock hole is provided at the end of the operation protrusion to prevent external operation. The locking is released by pressing the operation protrusion inwardly of the pillar main body and rotating the locking piece.

Further, preferably, the holding member 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 due to its own weight to the unlocked state of contacting with the restricting piece of the holding tool. It is made rotatable between the two.

[0007]

[Operation] 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 lower cutout 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 locked. When the pillar is rotated and the pillar body is inserted to a predetermined position, the locking piece is rotated by its own weight and the locking portion is locked through the lower cutout hole on the side surface of the pillar main body. It will be locked to and will prevent it from coming off. At the same time, the operating protrusion of the locking piece is projected from the upper notch hole on the side surface of the column body, and by locking the padlock in the hole of the protruding end, the locking piece is prevented from rotating and the retaining is complete. When the main body of the support column is removed, the padlock is unlocked and the operating projection is pressed from the outside to rotate the locking piece and release the locking.

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 notch hole 12 is provided on the side surface of the embedded cylinder 1 and a case 13 is formed so as to cover the notch hole 12 in a protruding manner. However, the present invention is not limited to this. It suffices if the stopper 41 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 lower cutout hole 21 is provided on one side surface corresponding to the locking hole portion 11 of the embedded cylinder 1. In addition, in the pillar main body 2, a retaining piece 3 is rotatably supported by a holder 3 fixed to an inner surface on one side above the road surface, so that the retaining piece 3 is prevented from coming off from the embedded cylindrical body 1. . Further, an upper cutout hole 22 through which the operation projection 42 of the locking piece 4 is inserted is provided on one side surface of the pillar main body 2 between the road surface and the holder 3.

The holder 3 is a metal fitting having a support shaft 31 for rotatably supporting the locking piece 4, and is attached to one inner surface of the column main body 2 by an appropriate means such as a screw and a rivet. . As shown in FIG. 3, the holder 3 is usually a support shaft 3.
One ends of the support plates 32 facing each other through which 1 is penetrated are connected to each other by a connecting plate 33, and a restricting piece 34 facing the connecting plate 33 is provided at the other end of the supporting plate 32. It is attached so as to abut on the inner surface of 2. The restriction piece 34 restricts the rotation of the locking piece 4 as described later, and it is preferable that the restriction piece 34 is normally provided, but it is not always necessary.

The locking piece 4 is made of metal, and its upper end is inserted into a space surrounded by the supporting plate 32, the connecting plate 33 and the restricting piece 34 of the holder 3 as shown in FIG.
It is rotatably supported by. That is, the rotation direction of the locking piece 4 is restricted by the holder 3. As shown in FIG. 1, the locking piece 4 has a hook-shaped locking portion 41 at one end, which is always attached to the locking hole portion 11 of the embedded cylindrical body 1 through the lower cutout hole 21 of the column body 2 due to its own weight. It is designed to be locked to. At the same time, the operation projection 42, which is provided on one side of the locking piece 4 so as to correspond to the upper cutout hole 22 of the strut body 2, is projected from the upper cutout hole 22. Operation protrusion 42
A hole 43 is provided at the projecting end of the padlock 5 so that the padlock 5 can be locked.

When the padlock 5 is unlocked and the operating projection 42 is pressed from the outside toward the inside of the column main body 2, the locking piece 4 is rotated to release the locking. ing. A protrusion 44 is provided on one side of the locking piece 4 at a position lower than the operation protrusion 42, and the projection 44 is brought into contact with the inner surface of the column main body 2 when rotating due to its own weight, so that the locking piece 4 is predetermined. It is designed to stop at a position.

Further, the locking piece 4 is rotated in the pillar main body 2 from the state in which the locking portion 41 is locked in the locking hole portion 11 of the embedded cylinder 1 by its own weight, and the locking is released. The shape and size may be such that they can be brought into a ready state. Usually, as shown in FIG. 1, from the locked state of the locking piece 4 by its own weight to the unlocked state (shown by a chain double-dashed line) of abutting against the restriction piece 34 of the holder 3 fixed to the inner surface of the column main body 2. The locking piece 4 is rotatable between them, and the rotation range is restricted so that the locking piece 4 does not rotate more than necessary.

[0014]

As described above in detail, in the prop of the present invention, such as the car stop, the locking piece is rotatably supported in the main body of the prop through the holder, and the locking part is supported by its own weight. At a position lower than the road surface, it is adapted to engage with the engaging hole portion of the embedded cylindrical body through the lower notch hole on the side surface of the strut body, and the operation protrusion projecting on one side of the engaging piece has the strut body. The lock is projected from the upper cutout hole on the side surface, and a padlock hole is provided at the end of the operation projection, and the locking is released by pressing the operation projection from the outside and rotating the locking piece. As a result, it is easy to prevent the pillar body from coming off and to release it. Moreover, the retaining mechanism is simple, it is easy to assemble, it is hard to break down, and the cost is low.

Further, since the locking piece is rotatable from the locked state by its own weight to the unlocked state in which it abuts against the restraining piece of the holder, the locking piece is required during transportation or construction. It does not rotate as described above, troubles due to unnecessary rotation of the locking piece can be prevented, and it is easy to handle.
