Key-operated vehicle lock, in particular anti-theft device with a Switch for interrupting a circuit.

The innovation relates to a vehicle lock, in particular an anti-theft device, with a switch to interrupt a circuit. laugh a simultaneous A proposal of this type is arranged in a lock or in a fuse of this type, key-controlled Guard locking of the lock itself used to generate optical and / or acoustic signals that the Have the task of notifying the driver of a motor vehicle that he has forgotten the key of a Remove the anti-theft device or the key when the engine has already stopped and the door of the Vehicle is open.

The innovation is based on the task of creating another simple option of this type, by means of whose one signal stream is controlled without affecting the effect of the anti-theft device that is otherwise present or the switch lock changes something.

The solution to this problem is, according to the innovation, that the key has a fixed curved path on which

an adjusting pin is spring-loaded. The 'adjustment pin controls a signal circuit and thus the activation or deactivation of an alarm signal.

The control parts connected to the adjusting pin can be used in a further development of the! of the lock housing, -which in the attachment housing further devices for lighting, for the lock- and keyhole lighting or for purposes of theft protection or to increase the security effect leg can be accommodated.

Further details of the inflation result from a graphic representation of a possible implementation of the same.

The drawing gives only the principle of the present Innovation again, it in no way exhausts the further, per se existing possibilities. It shows

Pig. 1 a conventional switching key or key associated with an anti-theft device with a curved path provided according to the innovation,

Fig. 2 is a longitudinal section through the lock of an anti-theft device or through a key switch in the locked position for the one secured by the anti-theft device Vehicle.

In Figure 1, a key designed according to the invention is illustrated in perspective. You can see that the Key has a curved path in the form of a cam disk 27.Each a preferred embodiment this can Cam disk 27 by means of a known welding process on the shaft or on those used for key handling

be, without other possibilities of connection being excluded, it unless the key and cam track would appear as a common pressed piece. In a special case the cam disk 27 is supported on a shoulder of the circular plate-shaped key head.

The position of the key pivot axis of the lock, which is coaxial to the lock inner cylinder axis, is made in such a way that that in the case of the "stop" or locking position immediately before the "drive" - "or release position of the lock the key is in a position opposite the lock, which is explained in more detail below with reference to FIG should be explained.

Εε should be emphasized beforehand that the shown Key shape can be replaced by any other shape; any other lock can take the place of the conventional lock shown. For example, the tumbler pins of a normal cylinder lock would be replaceable by tumbler plates, whereby the key would have a corresponding training. Cross-wrenches with a bore can also be used, as they are already known to be advantageous (compare French patent application PV 147 730 of April 11, 1968).

With a lock training - and - arrangement according to the figure of the drawing, 1 is the housing of the anti-theft device -s- or switch lock that receives the key 7, the cam 27 of which is in a corresponding recess of the Lock head can be received. It is 28 an insulating washer, which is produced, for example, by means of a press, with the housing 1 may be connected in any conveniently occurring manner.

A cam-controlled adjusting pin is also arranged 30, which is insulated and housed in the housing 1 so that it can move radially.

The adjusting pin 30 is limited on the one hand by a probe tip which rests on the cam disk 27 of the key. The other end of the adjusting pin 30 is hemispherical in order to create an abutment for a contact spring 31. A collar 30 ¹ on the adjusting pin 30 serves to limit the displacement path of the adjusting pin. . .,

A further contact spring 32 is arranged opposite the contact spring 31. Each of the two springs is with one cable 17, 18 each connected. j,

The housings do not need to be made of insulating materials. Metal housings can also be used if, for example, the actuating pin 30 itself consists of non-conductive materials. ■ the contact springs 31, 32 may be in such a case disposed on insulating materials and mutually isolated.

The mode of action of the innovation is as follows;

When the lock is in the stop position, has

brought the actuating pin into the cam disk 27 in the position shown in the figure, in which the contact springs are located 31 and 32 touch, so that a circuit is closed in which they and a signal device optical or acoustic type, if the circuit does not have both optical and acoustic devices for output having an alarm signal. The key that is not withdrawn ensures the occurrence of a signal or more of the same. So the driver is on it

alerted that he has not yet removed the key. The alarm signals sound or light up as long as the key is in the position inserted into the lock.

if the key is turned further This state can also / be maintained, if the course of the cam surface of the cam 27 is designed so that the position of the actuating pin 30 remains in FIG. However, it is useful to design the cam 27 so that the effect on the actuating pin 30 is omitted when the lock and key are in the unlocked position, otherwise the driver would be disturbed by further occurrence of the signal.

The rounded end of the actuating pin 30 remains in constant contact with the spring 31; the other way around the elasticity of the spring 31 ensures that the end of the actuating pin intended for scanning the cam disk 27 30 remains in constant contact with the curved path 27.

According to the design of the lock arrangement shown, you can special relays are omitted, so that it is a special economical design of an alarm device to prevent the key from being left in the lock when leaving the vehicle through the open door. As long as the door is not open, the So the driver is still at his place, for example to continue the journey after a stop, there is no reason to train the facility in such a way that an alarm is given in this case too, despite the fact that in Can be useful in individual cases.

The radial position of the actuating pin 30 in relation to the lock is not essential. It can also
