Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote locking device for 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 that moves forward and backward in a state of crossing its wheels is attached to the left side surface of a front fork or a rear fork forming a vehicle body frame. It is customary.

Then, the lock rod is pushed directly with a fingertip to lock the wheel so that the wheel cannot be rotated, and the extracted unlocking key is inserted again to retract the lock rod from the wheel. Has become.

[0004]

However, in the case of such a conventional technique, it is possible to quickly lock or unlock the wheels by a remote control operation while keeping a comfortable posture, for example, sitting on a saddle of a bicycle. It is not possible to do so, and the operator must be forced to bend over. Therefore, it is very difficult to use at night or for the elderly, and it is still inconvenient in operation due to the fact that it is arranged on the left side surface of the front or rear forks.

Particularly, when a large number of bicycles are juxtaposed in a limited bicycle storage space such as a school, a housing complex, or the front of a station, the wheel locking tool cannot be reached by an operator, so that the wheel can be locked or unlocked smoothly and reliably. As a result of the inability to do so, the adjacent bicycle often falls over.

In this regard, recently, a bicycle having a horseshoe-shaped wheel locking device that opens and closes like a handcuff mounted on the upper end portion of the rear fork is also found, and according to this, the operation of locking or unlocking the wheel is bent. There is an advantage that you can do it from the back of the bicycle.

However, since this is a horseshoe type that surrounds the rim of the wheel, it is not only liable to be damaged early due to adhesion of mud, etc., but it also becomes an obstacle when installing the luggage carrier on the bicycle. As a result, it is only applied to a bicycle that does not have a luggage carrier, and is inferior in versatility.

[0008]

SUMMARY OF THE INVENTION The present invention contemplates the improvement of such problems by virtue of its construction for advancing and retracting the wheels in a locking box fitted to the front or rear forks of the bicycle. A wheel locking device with a lock rod that can operate, an operation box that can be attached to any location such as the body frame and handle stem, a push-down operation lever that can move forward and backward, and a removable unlock key for returning When the operating lever is pushed in, the locking rod advances toward the wheel from the operating box to lock the wheel so that the wheel cannot be rotated, and the operating lever is also unlocked. When the lock rod is returned by the operation of inserting the key, the lock rod is retracted from the wheel into the operation box. It is characterized in that the operating lever and interlocked by a constant length of Putsu Shiyu pull cable.

[0009]

According to the above-mentioned structure of the present invention, by pushing the operation lever of the remote operation tool to operate, even if the user sits comfortably on the saddle of the bicycle, the wheels thereof are locked or unlocked so as not to rotate. It can be locked and anyone can conveniently use it.

Further, since the remote control tool can be attached to any place such as the body frame and the handle stem,
The present invention can be widely applied to any type of bicycle without restricting the installation of the carrier or the like.
