Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steering lock switch device that opens and closes when a key is inserted into or removed from the cylinder lock of the steering lock.

In the past, the operating mechanism of this type of warning switch was complicated, creating resistance when the key was inserted into the cylinder lock, making it difficult to open and close the switch smoothly. In addition, in Utility Model Application Publication No. 53-42188, since the contact terminal for opening and closing the switch is formed of an elastic spring member, the contact terminal may become sagging over time and the switch cannot be opened or closed. The drawback is that it disappears.

An object of the present invention is to provide an engaging element that moves when a key is inserted or removed, a swinging member that pivotally supports the intermediate portion and expands the movement of the engaging member, and a switch that comes into contact with the swinging member. The movable element is provided in the steering lock.

Hereinafter, a specific embodiment of the present invention will be described with reference to the drawings.

Fig. 1 is a cutaway side view of the main part of the present invention, in which A is a steering lock, a cylinder lock C is provided in the housing 1 of this steering lock A, and the cylinder lock C is moved to the front part. A movable engaging element 2 is provided, and one end 2' of this engaging element 2 faces so as to enter a key (not shown) insertion groove 3 provided in a cylinder lock C.

Further, the other end 2'' of the engaging element 2 is pivoted so that the short lever side end 4' of the swinging member 4, whose intermediate portion is pivotally supported to the housing 1 by a pin 6, comes into contact with the other end 2'' of the engaging element 2. The long lever side 4b of the swinging member 4 is urged by a spring 10 so that the short lever side end 4' of the member 4 fits into a notch hole 7 formed in the case 5 of the cylinder lock C.

The long lever side end 4'' of this swinging member 4 advances and retreats through a small hole 1' formed in the housing 1, and is connected to a so-called small switch B (commercially available product) fixed to the outer surface of the housing 1 of the steering lock A. ), the movable element 8 moves together with the swinging member 4 when the key is inserted or removed, and the switch B opens and closes.

In this way, in the present invention, the key insertion groove 3
Since one end 2' of the engager 2 is exposed inside, when the key is inserted into the cylinder lock C, the engager 2 comes into contact with the side wall surface of the key, and the engager 2 is pushed into the cylinder lock C.
At the same time, the long lever side end 2'' of the engaging element 2 presses the short lever side end 4' of the swinging member 4 while resisting the spring 10, so that the swinging member 4 rotates counterclockwise about the pin as a fulcrum, and the lever-side end 4'' of the swinging member 4 that is in contact with the mover 8 of switch B is separated, and switch B is activated.

As described above, the present invention provides a cylinder lock and an engager at a position orthogonal to the key insertion groove of the cylinder lock, with one end of the engager facing into the key insertion groove and the other end of the engager facing the key insertion groove. The intermediate part of the swinging member is provided on the outside of the cylinder lock, and the short lever side end is brought into contact with the end of the swinging member. When inserted into or removed from the cylinder lock, the movement of the engaging element is magnified by the leverage of the swinging member and transmitted to the movable element to operate the switch.
It has the feature that when the key is inserted or removed, the movement of the engager is expanded by the swinging member, and the switch can be opened and closed reliably.
