Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a locking device for a vehicle stop strut for restricting unauthorized entry of vehicles in parks, public facilities, and the like.

[Prior Art] The vehicle-supporting column is lowered into the outer cylinder buried in the ground when the vehicle is allowed to enter, while the column is required from the outer tube when the vehicle is prohibited. The length of the restraint chain is pulled up, and a restraining chain is stretched between the columns fixed at the pulling position.

Conventionally, a padlock attached between the upper flange portion of the outer cylinder and the lower side surface portion of the support has been used as a means for fixing the support at the pulled-up position.

However, the method using a padlock requires two people, one who secures the prop at the pulling position and the other who unlocks and operates the padlock, and it is often necessary to pull up and release the prop in many rows. It was troublesome and the workability was poor.

[Problem to be Solved by the Invention] Therefore, an object of the present invention is to provide a strut locking device capable of accurately pulling up and fixing a strut and releasing the fixation with good workability by one person.

[Means for Solving the Problem] Hereinafter, referring to the attached drawings, a locking device for a strut of the present invention includes a casing 3 housed and fixed inside a strut 1, and a casing 3 of the casing 3. The lock unit 7 fixed to the front plate portion 4 and having the key hole 6 directed to the opening 5 of the side wall 2 of the column 1, and the middle portion of the casing 3 is pivotally attached by a horizontal pivot 8 and the drive projection 9 at the upper end is attached to the side wall. The kick lever 11 protruding from the through hole 10 of the second shaft 2 and the middle portion of the casing 3 are pivotally attached to the casing 3 by the horizontal pivot shaft 12.
The stop lever 17 that locks the strut 1 in the pulling position by engaging with the receiving hole 16 of the, the spring 18 that urges the stop lever 17 to rotate in the locking direction, and the stop lever fixed to the lower end of the kick lever 11 The interlocking pin 20 engaged with the receiving groove 19 at the upper end of the lock lever 17 and the rotor 21 of the lock unit 7 are fixed to each other.
A stopper metal plate 24 that locks the kick lever 11 so that the kick lever 11 cannot be reversely rotated, and a spring 25 that urges the stopper metal plate 24 to rotate in the locking direction.

[Operation] When the column 1 is locked at the pulled-up position, the locking projection 13 of the stop lever 17 engages with the receiving hole 16 of the outer cylinder 14, and the stopper plate
The regulating projections 22 of 24 are engaged with the locking shoulder portions 23 of the kick lever 11.

In order to unlock the support 1 and store the support 1 in the outer cylinder 14, a predetermined key 26 is inserted into the key hole 6 of the lock unit 7 and the rotor 21 is rotated in the unlocking direction. By this rotation operation, the stopper plate 24 rotates in the counterclockwise direction in FIG. 1, so that the restriction projection 22 is disengaged from the locking shoulder portion 23.

Here, when the operator kicks the drive projection 9 of the kick lever 11 with the tip of the shoe and pushes it into the opening 10 of the column 11, the kick lever
11 rotates counterclockwise around the horizontal pivot 8. Along with this rotation, the interlocking pin 20 pushes the groove wall surface of the receiving groove 19, so that the stop lever 17 rotates in the clockwise direction about the horizontal pivot 12.

Thus, the locking projection 13 of the stop lever 17 is disengaged from the receiving hole 16 of the outer cylinder 14 and retracted into the pillar 1, so that the pillar 1 immediately descends by its own weight and is stored at a predetermined depth in the outer cylinder 14. To be done.

An operator pulls up the column 1 from this unused position, and the locking protrusion
When 13 comes to the position facing receiving hole 16, stop lever
The spring 17 is forced to rotate counterclockwise by the biasing force of the spring 18, and the locking projection 13 engages with the receiving hole 16.

This engagement prevents the column 1 from descending,
The operator removes his / her hand from the pillar 1 and inserts it into the lock unit 7 of the key 26, and rotates the stopper plate 24 back in the clockwise direction to
The regulating projection 22 is re-engaged with the locking shoulder portion 23 of the kick lever 11. As a result, the column 1 is locked and held in the use position.

[Embodiment] In the illustrated embodiment, another stop lever 28 is pivotally attached to the casing 3 by a horizontal pivot 27, and the locking projection 29 of the stop lever 28 is provided on the opposite side of the receiving hole 16. Disengage from the receiving hole 30. An operating pin 32 fixed to a side end portion of the stop lever 28 is engaged with the interlocking long hole 31 provided in the side protruding portion of the stop lever 17, and the stop lever 28 is pushed by the kick lever 11, It operates in synchronization with the stop lever 17.

The spring 18 for urging in the locking direction is also used as the stop lever 17, and the spring 18 constituted by the compression coil spring includes the spring receiving portion 33 on the lower end side surface of the stop lever 17 and the lower end side surface of the stop lever 28. The spring receiving portion 34 is fitted and supported. The biasing spring 25 of the stopper plate 24 is composed of a torsion coil spring,
One end of the spring 25 is wound around the spring receiving pin 35 at the end of the stopper plate 24, and the other end is wound around the spring receiving pin 36 fixed to the front plate portion 4 and the rear plate portion 37 of the casing 3. ing.

A stop pin 38 for controlling the rotation angle of the stopper plate 24 is fixed to the front plate portion 4. The horizontal axis 8 and the horizontal axis 12
Is fixed to the front plate portion 4 and the rear plate portion 37 of the casing 3, the spacer cylinders 39 and 40 are fitted to the horizontal pivot 8, and the spacer cylinders 41 and 42 are fitted to the horizontal pivot 12.

The casing 3 includes a left side plate portion 43 and a right side plate portion 44 with screws 45, 4
It is fastened and fixed to the side wall 2 of the column 1 by 6. In the lower part of the left side plate part 43, an escape groove 47 for the locking protrusion 29 is provided,
An escape hole 48 for the drive projection 9 is provided on the upper portion of the right side plate portion 44,
An escape groove 49 for the locking projection 13 is provided in the lower portion of the right side plate portion 44. In the side groove 2 of the column, the relief holes 50,51 of the locking projections 13,29 are provided.
Are provided so as to face the receiving holes 16 and 30.

In the present embodiment, the lock mechanism of the lock unit 7 is a simple lock having a simple structure in which two eccentric recesses are formed on the front surface of the rotor 21 to form the key hole 6 and two eccentric projections are formed at the tip of the key 26. However, as the lock unit 7, another known lock mechanism such as a cylinder lock may be appropriately selected and used.

In the present embodiment, the screw rod 52 is connected to the rotor body 21 by the spring pin 54, and the stopper plate 24 is connected to the screw rod 52 forming a part of the rotor 21 by the interposition of an appropriate spacer cylinder 53 and the nut 54. It is fixed.

[Advantage of the Invention] With the strut locking device of the present invention configured as described above, the stop lever 17 can be operated only by pulling up the strut 1.
The locking projection 13 of the is automatically engaged with the receiving hole 16 of the outer cylinder 14,
Since it is accurately held in the engagement position by the support 18,
The work of pulling up and fixing the can be extremely easily performed by one worker in a single operation.

When the drive protrusion 9 of the kick lever 11 is pushed in after the unlocking operation of the lock unit 7, the stop lever 17 rotates in the unlocking direction in association with the kick lever 11, and the lock protrusion 13 receives the lock hole 16.
Since it is detached from and retracted into the support column 1, the work of releasing the fixation of the support column 1 can be easily and smoothly performed by one operator, and the workability is excellent.
