Abstract

PROBLEM TO BE SOLVED: To prevent the rotation of a fore wheel by the handle itself of a bicycle, by providing a function, for unfixing the fixing of a handle to make it foldable, to the handle; and confirming the insertion of the handle between spokes to fix it intact when the handle is locked. SOLUTION: A function for facilitating the fixing of a handle for original steering, and folding the handle for locking is applied to the handle 1. When in a condition where a key 3 is locked, the handle 1 is folded to be placed between spokes 2 to prevent the rotation of a wheel; and it is impossible that the handle is raised to be restored to a normal condition, unless using the key 2 when the bicycle is parked; thereby making the rotation of the fore wheel impossible to prevent a burglary.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0101]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention folds a handle of a bicycle so as to be folded, and makes it impossible to rotate the front wheel by inserting a part of the handle between spokes of the front wheel of the bicycle. The key is to prevent theft.

[0092]

2. Description of the Related Art Conventionally, a bicycle is stolen as a function of locking a bicycle by passing a chain or the like through a wheel, or inserting a rod-shaped bracket between spokes to stop rotation of the wheel and to prevent theft. Was.

[0093]

In the conventional method of winding a chain or the like around a wheel, the chain is easily cut,
It is difficult to prevent theft. Further, the method of inserting a rod-shaped metal fitting between the spokes easily breaks the metal fitting (key) itself, and does not effectively prevent theft. In the conventional anti-theft (locking) method, it is possible to remove only the key without impairing the original function of the bicycle. Therefore, even if the bicycle is locked, the bicycle is stolen, and there is no end to the case of bicycle theft. In the present invention, the rotation of the front wheel is prevented by the handle of the bicycle itself, and even if you try to take it away, the handle is bent unless you release the key and return it to its original position. It is difficult to take away. Also, trying to unlock the key with excessive force is to damage the handle (the bicycle body). Destroying the key alone can improve the weaknesses of conventional anti-theft devices that could be stolen without any effect on the bicycle body.

[0093]

Means for Solving the Problems Now, the functions to be added to the conventional bicycle will be described. (A) The handle 1 is released from being fixed and has a function capable of bending. (B) When locking (bicycle parking), handle 1 is spoke 2
The function of the key 3 that can be fixed without any change is added after confirming that the key 3 has been inserted. In this case, the key may be locked by connecting the left and right handles passing between the spokes. (C) When using a bicycle, release the key 3, raise the left and right steering wheels, fix them, return to the conventional shape, and get on the bicycle. An apparatus as described above is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A steering wheel has a function to easily fix a rudder and to easily bend for locking. When locked, the handle flexes between the spokes, preventing the wheel from turning. When a bicycle is parked, it can be fixed in the above-mentioned state, and has a function and strength that the handle cannot be restored to a normal state unless the key is used.

[0086]

In the locked state, the steering wheel does not have a function to turn the rudder, and it is difficult to carry on or push away. Attempting to destroy the key by force
This is to destroy the bicycle body (handle), which significantly impairs the value (aesthetics) of the stolen bicycle. The present invention, in which the handle itself is used as a key to a bicycle, can dramatically reduce the number of victims who have been locked and stolen. In addition, the conventional bicycle key is no longer necessary, and the user is free from the hassle of carrying a chain-shaped key on a part of the bicycle even when the key is not used.

Claims (1)

[Claims] 1. A device in which a steering wheel is bent and fixed between spokes of a front wheel of a bicycle, the rotation of the front wheel is prevented by the steering wheel of the bicycle itself, and the steering wheel itself serves as a key for preventing theft. In this state, the steering wheel does not have the function to turn the rudder, making it difficult to ride or push and take away
