Abstract

PURPOSE:In a steering lock preferable for an open car to drain the rain water reliably by making a small hole at the predetermined position of a partition wall partitioning between a chamber containing a steering stopper member and an ignition switch. CONSTITUTION:A steering lock will release locking by inserting a key into the key hole 15 of a key cylinder 14 to rotate the rotator 9 thus to draw the locking rod 7 through a hanger 10 from the locking hole 13 of a collar 12 fitted on the steering shaft 11. At this time an ignition switch 17 is turned on to start the engine. Here a small hole 20 is made through a wall 18 partitioning between a chamber 5 containing the steering stopper member 4 including a locking rod 7 and the ignition switch 17. Said hole 20 is positioned such that while shifted to the right of the trailing edge 10a of the hanger when the stopper member 4 is at the locking position.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a steering lock mechanism for locking a steering shaft of an automobile. This invention relates to a water-resistant steering lock suitable for t-punk cars and the like.

elm anal early V 侭 V blood book τ completed W] gradient 1. Seiki's steering lock has the following drawbacks.

That is, the conventional steering lock includes a frame incorporating a locking rod for locking the steering link shaft and a rotator for operating the locking rod, and a key cylinder and an ignition switch operated by the rotator on both sides of the frame. All operations can be performed with the key inserted into the key insertion hole of the key cylinder.

Therefore, when such a steering lock is installed on an open car such as a convertible car, although the frame itself is water resistant, rainwater and dust that have entered the vehicle interior may enter the frame through the key insertion hole. , the cause of rust and the cause of rust
, it may freeze in the frame and cause malfunction.

In particular, in order to improve theft prevention, in a structure where a partition wall is used to separate the chamber housing the 0-king quart and the Ibnirashiron switch 295-, there are many parts of the chamber that communicate with external buttons. Corrosion may progress over a long period of time due to rainwater entering through the key insertion hole, potentially causing an unexpected accident. Incidentally, these various situations also occur when a Yuubishi car is left outside for a long period of time with its windows open.

In order to prevent theft of a steering lock in which a partition wall separates the steering locking member storage chamber and the ignition switch as described above, the present invention automatically removes rainwater, etc. in the locking member storage chamber. This is a book that proposes a structure that can discharge water to the outside.

A small through hole is bored in the lower part of the partition at a position closer to the opposite side of the steering column than the rear end of the locking member in the locked position, and rainwater inside the room is drained to the outside from the through hole. It is said that

11 Hereinafter, the present invention will be explained in detail with reference to a practical example shown in one drawing.

FIG. 1 is an overall cross-sectional view of a steering lock according to the present invention, in which a base portion 1a is fixed to a steering column 2 at the center of a frame 1.

A chamber 5 is formed for accommodating a steering blocking locking member 4 whose rear end is pressed by a spring 3. In the illustrated example, the engaging member 4 includes a locking rod 7 slidably positioned in a center hole 6 penetrating toward the steering column 2, and a low data 90 connected to the locking rod 7 by a bottle S and described later. It consists of a hanger 10 whose position is controlled by the rotation angle. The tip end 7a of the locking rod 7 is connected to the steering shaft 1 inserted into the steering column 2.
When the locking rod 7, facing the collar 12 of No. 1, is in the position shown by the solid line protruding from the frame l,
The tip end 7a of the locking rod 7 enters the locking hole 13 of the cup 12 and the steering shaft 11 is locked. A key cylinder 14 assembled to -@ of the frame 1 is connected to one end of the low take 9, and the four take 9 is rotated by a key inserted into a key insertion hole 15 of the key cylinder 14. And the key cylinder 1
An ignition switch 17 is attached to the side of the frame opposite to 4 with a mounting bolt 16, as shown in the second figure. A partition wall 18 closes the space between the chamber 5 and the ignition switch 17. A trigram.

The low take 9 and the ignition switch 17 are connected by an extension 9a of the low take 9 extending through a hole 19 in the partition wall 18.

According to the invention, the isolation 18 is provided with small through holes 20 for draining water. This is because the through hole 20 is provided at a position 9 which is closer to the opposite side of the steering column 20 than the rear end tea of the hanger 10 when the locking member 4 is in the locked position shown by the solid line in FIG.

It is not possible to externally operate the locking member 4 through this through hole 20.

Since the steering lock according to the present invention has one or more configurations, moisture that has entered the interior of the chamber 5 through the key insertion hole 15 of the key cylinder 14 flows out to the ignition switch 17 side through the through hole 20. Since this ignition switch 17 is only attached to the frame l by the mounting hole 16, moisture will flow out from the gap between the ignition switch 17 and the frame 10. Further, since the through hole 20 is provided at the position described above, even if the ignition switch 1f is removed from the frame 1, the locking member 4 cannot be operated externally.

Providing the through hole 20 does not impair theft prevention.

In conclusion, according to the present invention, it is possible to obtain a steering lock that is highly anti-theft and has excellent water resistance.
