本発明はステアリングロツク装置が施錠中に、

クの破壊防止装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention provides that while the steering lock device is locked,
This invention relates to a steering lock destruction prevention device that prevents the steering lock from being destroyed by tools.

とができるので車を盗まれるという欠点があつ
た。 Conventionally, in this type of device, when a key inserted into a cylinder lock is removed, a locking rod protrudes and engages a shaft in a steering column, thereby preventing rotation of the steering wheel. In this way, by preventing the handle from rotating, theft is prevented, but even so,
If a tool such as a crowbar was hooked to the steering wheel and the steering wheel was forced to turn, the steering lock device would be destroyed and the steering wheel could be turned freely, making it possible for the car to be stolen.

グロツクの破壊防止装置にある。 The present invention has been made in view of these drawbacks, and its purpose is to prevent the steering device from being destroyed even when the steering wheel is forcibly turned by a tool or the like. To,
A slidable pipe with a lug around the periphery is fitted onto a shaft to which a handle is fixed and a pin is implanted, and this pipe is constantly urged in the axial direction by a spring, and a When the locking rod that protrudes when the key is removed from the cylinder lock is inserted into the elongated hole, that is, when the handle is forcibly rotated while the lock is locked, the pin and rack resist the spring. However, the steering lock can be slid in the axial direction without bending the locking rod, and the steering lock cannot be operated smoothly.
以下、従来の実施例と共に本発明の一実施例を
図面により説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings together with a conventional embodiment.

る。 FIG. 1 is a diagram showing one embodiment of the fraudulent means, and A is a tool that is hung on the handle B to forcibly rotate the handle B. C is the steering column,
A shaft 1 is fitted inside the steering column C, and one end of the shaft 1 is fixed to a handle B, and the other end is connected to a steering axle (not shown). Reference numeral D represents a steering lock device, and a cross-sectional view of the main part of this device is shown in FIG. The cylinder lock 3 is rotated by the cylinder lock 3 (not shown), the check lever 4 is activated when the key is inserted into or removed from the cylinder lock 3, and the rotor (not shown) of the cylinder lock 3 rotates with the rotation of the key. A rotating cam 5 that rotates at times, a hanger 6 engaged with the rotating cam 5, a spring 7 that constantly biases the hanger 6, and a locking rod 8 fixed to the hanger 6 are provided. When the hanger 6 is moved backward while rotating the rotary cam 5 in the unlocking direction, the locking rod 8 resists the spring 7 and locks the shaft 1.
Since the shaft 1 and the handle B are separated from the groove 9' of the pipe 9 fitted in the shaft 1, the shaft 1 and the handle B rotate together.
また、従来はパイプ９をシヤフト１にノツクピ
ン１０，１０′で固着しているので、施錠中にハ
ンドルＢと共にシヤフト１が無理に回動させられ
ると、ノツクピン１０，１０′が切断されるか、
または施錠杆８が折れ曲つたり、あるいはパイプ
９が削れたりするので、施錠状態を確保すること
ができなくなる。 Furthermore, conventionally, the pipe 9 is fixed to the shaft 1 with the knock pins 10, 10', so if the shaft 1 is forcibly rotated together with the handle B while the lock is locked, the knock pins 10, 10' may be cut off.
Alternatively, the locking rod 8 may be bent or the pipe 9 may be scratched, making it impossible to maintain the locked state.
そこで、本発明はハンドルＢを固着するシヤフ
ト１にスプリング１１とパイプ１２を嵌装する。
このパイプ１２に形成したラツク１２′はシヤフ

ト１が施錠中に回動させられたとき、ピン１３が
パイプ１２′面を滑動しながら、パイプ１２を軸
方向にスプリング１１に抗して押動する。 Therefore, in the present invention, a spring 11 and a pipe 12 are fitted to the shaft 1 to which the handle B is fixed.
A rack 12' formed on this pipe 12 comes into contact with a pin 13 implanted in the shaft 1. Further, the locking rod 8 is inserted into the elongated hole 14 formed in the axial direction of the pipe 12 and the pipe 12 is locked. When the shaft 1 is rotated together with the handle B during locking, the pin 13 slides on the surface of the pipe 12' and pushes the pipe 12 in the axial direction against the spring 11.
このように本発明は、スプリングに付勢された
パイプのラツクとシヤフトのピンの接触により、
シヤフトの回動時に大きな抵抗を生じさせハンド
ルの操作を円滑におこなうことができないように
すると共に、施錠杆の折曲もなくなるので、盗難
の防止と共にステアリングロツク装置の破損も防
止できるという効果を奏する。 In this way, the present invention allows the rack of the pipe and the pin of the shaft to contact each other, which is biased by the spring.
This creates a large resistance when the shaft rotates, making it difficult to operate the steering wheel smoothly, and also eliminates bending of the locking rod, which has the effect of preventing theft and damage to the steering lock device. .
