Abstract

PURPOSE:To prevent a locking bolt from being damaged due to the overstraining rotation of a steering shaft, by setting an angle larger than a prescribed value and defined between the sides of the tip of the locking bolt in the direction of the rotation of the steering shaft. CONSTITUTION:Such an angle theta as to cause a thrust Fx to disengage a locking bolt 8 out of an engaging hole 10 when an overstraining force F acts from a steering shaft 9 to the locking bolt, is set between the sides 8A, 8B of the tip of the locking bolt in the direction A of the rotation of the steering shaft. The angle theta is prescribed as theta>2sin<-1>S/D where D denotes the outside diameter of a collar 11 and S the distance between the open edges (a) of the engaging hole 10, so that the locking bolt 8 is disengaged out of the engaging hole 10 against a spring force acting to the bolt, when excessive torque has acted to the steering shaft 9.

。As is well known, a conventional steering lock has a structure as shown in the first and second figures. That is, in the steering lock body 2, which is attached to the steering column 1, a rotor 8, a cam 4, and an ignition/on switch 5, which are operated by a predetermined key, are built into the part near the head of the steering lock body 2. The cam 4 controls a locking arm 7 pushed by a spring 6. A locking bolt 8 that is driven by the hanger 7 is incorporated into the steering lock body z, and a tip portion 8δ of the locking bolt 8 is inserted into the steering lock body z.
is the locking hole 10 of the steering shaft 9.
Locking of the collar 11 firmly attached to the steering shaft 9
Stay tuned for T1.10. Once, key cylinder 8
When the key is removed, the tip 8a of the locking bolt 8 is pushed into the locking hole IO by the force of the spring 6, as shown in the figure, and the steering shaft 9 is locked.

In the structure shown in the diagram, the Ministry of Health, Labor and Welfare, which suffered 11 crises in this way,
Due to the excessive transmission of rotational torque, the locking bolt 8 may be sheared or the fixing force between the steering shaft 9 and the collar 11 may be lost.

The purpose is to obtain a structure that will not be lost, and the side surface of the locking bolt tip in the direction of rotation of the steering shaft or the side surface of the locking hole corresponding to the same tip side surface K, 2-5" main (herein) , D Ni Steering 1] It is proposed to provide an angle larger than the outer diameter of the shaft portion (S-width dimension of the locking bolt at the outer peripheral position of the steering shaft portion).

以下、第３−について本発明の実施例の詳細を説明する
。Hereinafter, the details of the embodiment of the present invention will be described for No. 3-.

ている。Figure 3 is a sectional view equivalent to Figure 2 showing an embodiment of the present invention.
The feature of the present invention is that the opening of the locking hole 10 of the collar 11 (
ita and the inclined complete sides 8A, 8B of the locking holder 8 that engage with it. That is, the tip side surface 8A facing the rotation direction A of the steering shaft 9,
8B is formed at an angle θ such that when an unreasonable force F is applied from the steering shaft 9, a thrust F 2 is generated that causes the locking bolt 8 to disengage from the locking hole 10.

The limit that can be obtained is when the complete side surfaces 8A and 8B coincide with the line segment connecting the center ○ of the steering shaft 9 and the opening edge a of the locking hole IO, so the angle formed by these line segments is θ, Then, the condition is that θ>0□. However, the outer diameter of the collar is D,
It is sufficient if there is a relationship υ of the locking bolt 8 corresponding to the distance between the opening edges a of the locking hole 10, that is, the outer peripheral position of the collar 11.

くなる。As is clear from the above description, in the steering lock of the present invention, when excessive torque is applied to the steering shaft 9 while the steering shaft 9 is locked, the locking occurs from the locking hole 10 against the force of the spring 6. Since the bolt 8 is removed, the steering lock will not be destroyed by forcing the steering shaft 9 to turn M.

。Then, the locking bolt 9 that has come off from the locking hole lO is
When aligned with the locking hole 10, the force of the spring 6 causes the locking hole l to be aligned again.
Since it enters into the O, the theft prevention function is not lost.
