Description

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to an improved bicycle locking device, and more particularly to an improved bicycle locking device that can be used as a locking device and can also be used as a frame on which objects are placed.

[0002]

2. Description of the Related Art Conventional bicycle locking devices are known. When a conventional bicycle locking device is unlocked and a bicycle is driven, the bicycle locking device is not required for driving, and therefore, the bicycle is generally driven in a basket attached to the bicycle.

[0003]

The conventional bicycle locking device has been handled as described above. If the bicycle rocks due to undulation on the road while driving the bicycle, the locking device may jump out of the basket. In addition, a hook is attached to an arbitrary position of the bicycle and a lock device is hung thereon, but it is inconvenient to ride the bicycle.

[0004] In general, general bicycles for competition are light in weight. For this reason, even if a lock device for preventing theft is provided, a frame or the like for placing articles is not provided.

Therefore, when an article is to be mounted on a vehicle body, there is no appropriate position for placing the article, which causes inconvenience in use.

[0006] As described above, in view of the drawbacks of the conventional structure that after locking is released, an appropriate position for placing the lock device cannot be obtained, and the locking operation cannot be completed from the appropriate position. As a result, the inventor has made intensive studies and tried to improve it, and has succeeded in developing the present invention. That is,
SUMMARY OF THE INVENTION It is an object of the present invention to provide a lock device capable of turning a latch insertion hole at a different angle by fixing the device to a vertical pipe member of a bicycle and rotating the lock device body.

Another object of the present invention is to provide a lock device which can be changed to a frame on which articles are placed after the lock is released, or which can be attached to a vehicle body at an appropriate angle so as not to affect the operation of the bicycle. And

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a lock device according to the present invention has a sleeve body and a cap body, and has a fixing seat on one surface of the sleeve body. The seat attaches and secures the locking device to the longitudinal pipe member of the bicycle. A storage chamber is provided at one end of the sleeve body, and a spring and an engagement means are stored in the storage chamber. Further, a pressing tip is provided above the storage chamber, and controls the engagement or release operation of the engaging means with the engaging hole of the lock device main body by the pressing tip. Further, by rotating the lock device main body, the insertion hole of the latch can be turned to a different angle, and the locking and releasing operations are facilitated. Further, after the lock is released, the latch is fixed at a fixed position, so that it is possible to provide a lightweight and simple article that also has an effect as a frame on which the article is placed. This is also one of the features of the present invention.
