DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for remotely locking wheels of a bicycle.

[0002]

2. Description of the Related Art In a conventional bicycle, a push-in type wheel locking device having a locking rod which moves forward and backward in a state of crossing the wheel is mounted on the left side surface of a front fork or a rear fork forming a body frame. It is customary.

The locking rod is pushed directly by a fingertip to lock the wheel so that it cannot be rotated, and the unlocking key is inserted again to retract the locking rod from the wheel. Has become.

[0004]

However, in the case of such a conventional technique, it is possible to lock or unlock the wheels quickly and remotely in a comfortable position, for example, while sitting on a saddle of a bicycle. It is not possible to do so, and the user must be forced to bend down in operation. Therefore, it is very difficult to use at night or for the elderly, and it is still inconvenient to operate it in combination with being arranged on the left side of the front fork or the rear fork.

In particular, when a large number of bicycles are arranged side by side in a limited bicycle storage area such as a school, an apartment complex, or a station, an operator cannot reach the wheel locking tool, and the wheels are locked or unlocked smoothly and securely. The inability to do so often causes the adjacent bicycle to fall over.

[0006] In this regard, there has recently been seen a bicycle in which a horseshoe-shaped wheel locking device that opens and closes like a handcuff is attached to the upper end of a rear fork. According to this, locking or unlocking of the wheel is performed. There is an advantage that it can be done from behind the bicycle without any problems.

[0007] However, since this is a horseshoe shape surrounding the rim of the wheel, it is not only easily damaged due to adhesion of mud and the like, but also becomes an obstacle when installing a carrier on the bicycle. As a result, it is only applied to bicycles without a carrier and is inferior in versatility.

[0008]

Spring receiving pin (48) and pivot pin (60) from the lower position
It is overhanging in parallel with.

That is, the operation lever (47) is moved in FIGS.
When it is pushed down like 0 or 11, it turns
The lock plate (59) is resiliently pressed by the locking spring (61).
Then, the upper surface of the spring receiving pin (48) is shut off by itself.
And push the operating lever (47)
It is designed to be kept locked and unlocked in that case
Pull out the key (D) from the operation box (45) just above
You can take it out and carry it with you.

On the other hand, the unlock key (D) is inserted and pushed
Operation, the rotary lock as shown in FIGS.
The plate (59) is also centered on the pivot pin (60).
Rotate in the opposite direction while resisting the urging force of the rock spring (61)
Acts and retreats from the upper surface of the spring receiving pin (48) by itself.
And the operation lever (47) is
Self-unlocked by the urging force of the spring (49)
It will be restored. In its return state, the unlock key
(D) cannot be extracted.

(63) is rotated to achieve the above effect.
For multiple unlocking keys protruding from the surface of the lock plate (59)
An induction key, which allows the unlock key to be
