本発明はステアリングロツク装置が施錠中に、
工具で破壊されないようにしたステアリングロツ
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.

ンドルにバールなどの工具を引掛けて、無理にハ
ンドルを回動させれば、ステアリングロツク装置
が破壊されて、ハンドルを自由に回動させること
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, theft is prevented by preventing the steering wheel from turning, but even so, if a tool such as a crowbar is hooked to the steering wheel and the steering wheel is forced to turn, the steering lock may be disabled. The disadvantage was that the device could be destroyed and the steering wheel could be turned freely, allowing the car to be stolen.
本発明は斯る欠点に着目して成されたものであ

いようにしたステアリングロツクの破壊防止装置
にある。 The present invention has been made by focusing on such 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 rotatable elastic pipe with a split groove is attached to the shaft to which the handle is fixed, and the locking rod that protrudes when the key is removed from the cylinder lock is engaged in the split groove, that is, when the lock is locked. When the handle is forcibly rotated, this pipe expands while still being engaged with the locking rod, allowing the shaft to rotate against great resistance without bending the locking rod. In addition, there is a destruction prevention device for the steering lock that prevents smooth operation of the steering wheel.
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.

で、このシヤフト1とハンドルBが共に回動す
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。 In addition, 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、本発明は弾性材から成るパイプ11に
割溝11′を形成すると共にこのパイプ11の内
周壁面12にシヤフト13と同形、すなわち対向
する側の面を平面1a且つ弧面1bに形成し、従
来のように断面が円形ではなく、異形する。この
ようなパイプ11をシヤフト13の膨出面14に
当接するまで嵌装し、さらにこのパイプ11がシ
ヤフト13から離脱したりしないように、シヤフ
ト13に形成した小孔13′にピン15を嵌入す
る。 Therefore, in the present invention, a groove 11' is formed in the pipe 11 made of an elastic material, and a groove 11' is formed on the inner circumferential wall surface 12 of this pipe 11 in the same shape as the shaft 13, that is, the opposing surface is formed into a flat surface 1a and an arc surface 1b. , the cross section is not circular like the conventional one, but has an irregular shape. The pipe 11 is fitted until it contacts the bulging surface 14 of the shaft 13, and the pin 15 is fitted into the small hole 13' formed in the shaft 13 to prevent the pipe 11 from coming off the shaft 13. .
第4図1および2は施錠時の要部断面図であつ
て、1は施錠中、2は不正に解錠されたときの作
動図であり、矢印のようにシヤフト13が無理に
回動させられたとき、パイプ11の割溝11′の
一端が施錠杆16に係合したまま拡開し且つ所定
位置で復帰する。 FIGS. 4 1 and 2 are sectional views of the main parts when the lock is locked, 1 is a diagram of the operation when the lock is locked, and 2 is an operation diagram when the lock is illegally unlocked. As shown by the arrow, the shaft 13 is forced to rotate When the pipe 11 is opened, one end of the groove 11' of the pipe 11 expands while being engaged with the locking rod 16 and returns to a predetermined position.
このようにシヤフト13もパイプ11の内周壁
面も円形になつていないので、ハンドルBの運転
操作が円滑におこなうことができない。 As described above, since neither the shaft 13 nor the inner circumferential wall surface of the pipe 11 is circular, the handle B cannot be operated smoothly.
第5図のようにパイプ17を弾性を有する樹脂
材にしてもよく、そのときは樹脂の磨滅を少なく
するために、割溝17′の両側縁に高張力鋼板1
8,18′をパイプ17の成形時にインサートす
るとさらに有効である。 As shown in FIG. 5, the pipe 17 may be made of an elastic resin material. In that case, high-tensile steel plates are placed on both sides of the groove 17' to reduce wear of the resin.
It is more effective to insert the tubes 8 and 18' when forming the pipe 17.
本発明は以上のようにパイプに割溝を形成する
と共に、このパイプを弾性材としたので、施錠中
にハンドルを無理に回動させられたとしても、施
錠杆あるいはパイプの破損がなく、しかも盗難も
未然に防止し得るという効果を奏するものであ
る。 In the present invention, as described above, the groove is formed in the pipe and the pipe is made of an elastic material, so even if the handle is forcibly turned during locking, the locking rod or pipe will not be damaged. This also has the effect of preventing theft.
