Description

[Detailed Description of the Invention] The present invention relates to a locking device for, for example, a pole that can be freely retracted from the ground.

In general, for poles that can appear on the ground,
In addition to the mechanism for keeping the pole standing on the ground, a locking device is usually built in as a safety measure to prevent unnecessary, mischief, or accidental entry by outsiders.

By the way, the conventional locking device employs a screw type, in which a pole is set up on the ground and then rotated to cause a stopper to protrude from the surface of the pole.

However, the turning operation requires a lot of effort and time is wasted when locking and unlocking a large number of poles.

Therefore, the present invention aims to provide a device that can lock and unlock with an extremely simple operation.One embodiment of the present invention will be explained below with reference to the drawings. A locking device 3 is installed below the pole 1 pulled out from the outer cylinder 2.

This locking device 3 is attached across the pole 1, and includes a sheath body 5 having openings 4 and 4' on the surface of the pole 1, and a sliding body 6 projecting outward from the pole 1 from one opening 4 of the sheath body 5. It consists of

More specifically, the sheath body 5 has one opening 4 formed with a slightly smaller diameter, and grooves 7 formed at appropriate locations.

Furthermore, the sliding body 6 has one half formed with a small-diameter protrusion, and the other half formed with a recess 9 whose bottom surface is an inclined surface 8 facing away from the protrusion, and communicates with the recess 9 from the protrusion side end surface. A communication side 10 having an appropriate cross-sectional shape is formed.

Reference numeral 11 denotes a moving element such as a sphere, which is fitted into the sliding body 6 so as to be movable along the sliding direction, and is projected to the top of the sliding body 6 when it is above the inclined surface 8. 11 is constantly pressed upwardly of the inclined surface 8 by a spring 12.

Reference numeral 13 designates a claw piece that fits into the groove 7 of the sheath body 5 and holds the sliding body 6 in a predetermined position, and 14 designates an elastic body for storing the sliding body 6 protruding from the surface of the pole 1 into the sheath body 5. .

Thus, the slider 6 was equipped with a slider 11, an elastic body 14 was provided on the small diameter portion, and the slider 14 was inserted into the sheath body 5, and the claw pieces 13 were fitted into the grooves 7 to be housed in the sheath body 5. As the stroke advances and retreats further from the state, the small diameter portion protrudes from the sheath body 5 against the elastic force of the elastic body 14, and the sheath body 5 is attached transversely to the pole 1.

In the unlocked state, that is, when the pawl 1 is in a state where it can be inserted into the outer cylinder 2, the sliding body 6 is housed in the sheath body 5 (Fig. 2), and when locking is performed, the elastic body 14 is The sliding body 6 is pushed forward against the pressure to cause the tip of the sliding body 6 to protrude.

At this time, even if the slider 11 temporarily stops against the movement of the slider 6, since the bottom surface is the inclined surface 8, there is no problem with the movement of the slider 6, and the slider 11 (or Since it is pressed by the spring 12, when the sliding body 6 finishes its movement for protrusion, it is pressed upwards on the sloped surface 8 and is press-fitted between the sloped surface 8 and the sheath body 5. The sliding body 6 is fixed to the sheath body 5 in the protruding state (the third
figure).

For unlocking, an unlocking body (not shown) is inserted into the communication cavity 10 that communicates with the recess 9 into which the slider 11 is inserted, and the slider 11 is moved against the elastic force of the spring 12. It is pressed to release the press-fitted state, and when the press-fitted state is released, the sliding body 6 becomes in a slidable state and can be stored.

At this time, the sliding body 6 is applied with a force in the storage direction by the elastic body 14, and is stored by itself due to the elastic force.

The present invention is constructed as described above, and can be locked by simply pressing the sliding body 6 housed in the sheath body 5, and can be unlocked by pressing the slider 11 through the communicating cavity 10. These operations are extremely simple,
Not only can this be accomplished in a short period of time, but the locking state, that is, the protruding state of the sliding body 6 is reliably maintained, and the risk of accidental retraction of the pole 1 due to tampering or the like is prevented.

Furthermore, if the sliding body 6 is provided with elastic force in the storage direction by the elastic body 14, the sliding body 6 will automatically be stored in the sheath body 5 upon unlocking, making the unlocking operation even easier. It will become.

As mentioned above, the locking device of the present invention is easy to operate and can be operated reliably, and is extremely useful as a locking device for a pole that can be freely retracted from the ground.
