Burglarproof Device for Bicycle and Bicycle with the same

The present invention relates to a bicycle, and in particular, in order to effectively prevent theft of the bicycle by restraining the nut, which is essentially used to fix the wheel of the bicycle, in both the QR (Quick Release) lever method and the conventional nut method, so as not to rotate and loosen. It relates to a bicycle anti-theft device and a bicycle having the same.

In general, a bicycle refers to a light, convenient device that allows the driver to step on the lungs with two feet and turn the wheels through the chain. Such bicycles are being distributed to many families as a way to provide a moderate amount of exercise to the modern people who have less exercise, including hobbies such as hiking, and in recent years, the population of bicycles has exploded due to the government policy encouraging cycling. It is increasing.

As bicycles have high oil prices and eco-friendliness, the penetration rate has increased significantly, and bicycle performance has also improved. As bicycles with expensive parts are popularized, theft accidents are frequently occurring. When users keep their bicycles, they usually have no difficulty in keeping their bicycles safe if they live in a private house with a space such as a yard, but they are shared by several people in a group building or subway station such as a townhouse or apartment. Because the outsider can be accessed at any time, the risk of being stolen is very high if the bicycle is stored without a separate means.

Therefore, when the bicycle is stored, an antitheft device for preventing theft is frequently used. One of these types of anti-theft devices is a method of tying bicycle wheels using wires to external fixtures such as columns.

In this case, however, the use of a cutter made it easy to cut the wires in less than three seconds, so the entire bicycle was stolen.

In addition, even if the wire is not cut as described above, the wheel, which is a main component, can be removed from the main body by simply releasing only one nut that fixes the wheel of the bicycle to the fork. That is, it can be easily understood with reference to FIG. 1. Recently, as shown in FIG. 1, a quick release (QR) lever 40 is widely used so that a user can easily detach and combine a wheel of a bicycle from a main body. The QR lever 40 is composed of a rotating shaft 41 penetrating the hub of the bicycle wheel, a nut 44 provided on one end of the rotating shaft 41, the pressing member 42 and the release lever 43. According to the QR lever 40, the rotation shaft 40 is inserted into the fork of the bicycle, and then the nut 44 is rotated clockwise to tighten it first, and then the pressing lever 42 is operated by operating the release lever 43. Advance to the nut (41a) to press the wheel is stable to the fork.

The emergence of such a QR lever 40 has the advantage that the user owns the bicycle is very convenient for assembling and disassembling the wheel of the bicycle from the main body, while causing a fatal problem that can be easily stolen. For example, the QR lever method can be stolen in about 3 seconds and the nut method in about 7 seconds.

On the other hand, although not shown in the drawing, in the conventional nut system having nuts at both ends of the rotating shaft, as in the QR lever system, it is necessary to simply loosen one of the nuts, which has a fatal weakness in theft.

Therefore, it is urgent to develop a technology that can effectively prevent theft of the bicycle by improving these prior arts.

In addition, there is no company that specializes in making bicycle locks in the courtyard of three major bicycle makers, and most of them are imported from China, and the countries that make bicycle locks include the United States, Germany, Taiwan, and Japan. Therefore, it is urgent to develop bicycle racks that can not be left behind even in Korea.
