Electronic anti-theft device, especially for motor vehicles

The invention relates to an electronic anti-theft device, especially for motor vehicles. In the field of anti-theft devices for automobiles and / or others In addition to the known devices, purposes are essentially electrical or electromechanical Effectiveness or type also electronic anti-theft devices have been proposed in which pulses of various types are used, but in which the switch-on or triggering and switching off does not take place with magnetic pulses. In contrast, the present invention is based on an electronic anti-theft device that comes with magnetic pulses is controlled and in a special way, if not only and exclusively, suitable for this is, on motor vehicles in general, both on motor vehicles with petrol engines as well as those with diesel engines, to be applied. The main object of the present invention is to provide an electronic anti-theft device to create that works in a simple, absolutely safe and reliable way and in which switching on or off

Triggering and switching off is easy, convenient and practical, using a simple and economical permanent magnet can be used, which is conveniently arranged and guided or contained, e.g. B. in a key holder or key case or in another than Pocket device usable object.

For the above purpose it is provided according to the invention in the new electronic anti-theft device, that it works with magnetic impulses, that it essentially has the following parts:

a) an electronic control center that has a continuous contains electronic pulse counter;

b) a pulse reading or scanning device for reading the magnetic pulses, which is connected to the continuous electronic pulse counter of the electronic control center, and

c) a magnetic activator designed as a pocket device for delivering pulses to the control center via the pulse reading or scanning device;

and that the electronic control center can be connected to various organs and / or parts to be protected and secured or can be connected to these and is preset so that a count up to a predetermined one Number of pulses and then a return to the NuI1 position can take place in order to switch on and turning off the anti-theft device based on the pulses supplied to her with the magnetic activator

and to control the activation or activation of an acoustic and / or optical signal generator in the event that that the protected organs and / or parts are broken open or damaged. Here z. B. the arrangement be made so that the electronic control center is connected to an electrical energy source and includes a temporizer or timer for regulating and setting the duration of the alarm signals. Preferably can the pulse reading or scanning device has an indicator light for making the pulse reading or scanning device visible containing impulses passing through. Appropriately can it can be provided that the magnetic activator, which is designed as a pocket device, is formed by a magnetic block which is preferably in a key holder or container is included and contained and the pulse reading or scanning device at intermittent intervals can be brought close or approximated to the electronic control center switch-on and switch-off pulses to send.

In the drawing is an embodiment of the subject of the invention shown. Show it:

The device according to the invention consists of three separate ones Put together: an electronic control center 1, a pulse reading or scanning device 2 and a magnetic activator 3, these parts are each on their own and separate shown in Figures 4, 5 and 6 of the drawing.

The electronic control center 1 contains in one Body or housing 4 an electronic circuit of the type shown in Figure 7 of the drawings, including a continuous electronic Contains pulse counter, which is preferably set so that it counts ten pulses each time and when this is reached Number of pulses return to the zero position

(Reset) can cause. The electronic control center also contains a timer or temporizer 25 which is intended to determine the activation time of the anti-theft device to be regulated if this is switched on or triggered in the event of a break-in.

The pulse reading or scanning device 2 contains e.g. B. a tube or piston interrupter, not shown ("interruttore ad ampolla") occurring as a result of an intermittent Applying the magnetic activator 3 can be made effective, and which is intended to be resulting impulses for the continuous impulse counter the electronic control center 1 via a connection 13, see FIGS. These impulses will be made visible by means of a light 14 contained in the body of the pulse reading or scanning device.

In turn, the magnetic activator 3 is formed from a magnetic block 23, which is preferably in one Key case 24 is arranged and enclosed, see Fig. 6, and as such, of the other components the anti-theft device is separated, it being used as a pocket device is designed and can be used in a convenient manner.

For using the anti-theft device described above on a motor vehicle is the electronic control center housed and fastened in a receptacle,

the ζ. B. is provided in the engine compartment of the vehicle itself, while the continuous electronic pulse counter 2 z. B. with the help of a wing 28, which is provided on the corresponding body of the device 2, on the seal of the Windshield of the vehicle is attached, see. Fig.

1. The electronic control center 1 is then with the help of a terminal board or terminal box 5, which or which is provided on the outside of its body or housing 4, with the pulse reading or scanning device 2, with the electrical power source or battery 6 of the vehicle as well connected to some parts or organs of the motor vehicle to be protected and secured, such as B., see. Fig. 1, the means 7 for closing the _x doors of the vehicle, the means 8 for closing the hood, the means 9 for closing the trunk, it can also be connected to the car radio, the starter block 10, etc.

In the case of a motor vehicle with a gasoline engine, see.

2, the electronic control center 1 could also be connected to the ignition distributor 11 and the coil 12, while in the case of a vehicle with a diesel engine, see FIG. 3, the electronic control center 1 could also be connected to the pump 15 for the fuel or to the Elektroventi1 and an additional one Relay 16 could be provided.

In any case, the electronic control center is then used 1 with an acoustic and / or optical signal generator

17 connected for alarm in the event of a break-in and an intervention in or on any of the protected parts of the motor vehicle is used.

For switching on or triggering the anti-theft device it is enough if you add any number to the continuous pulse counter of the electronic control center 1 of pulses smaller than ten by intermittently bringing the magnetic activator closer or applying it 3 on the pulse reading or scanning device 2 notifies.

When the anti-theft device is switched on, generated opening a door or the bonnet or trunk lid or tampering with any protected one triggering or switching on another part of the motor vehicle the acoustic and / or optical signaling device that remotely reports this break-in or damage.

Also a possible introduction of the key into the starter block produces on the one hand the activation of the alarm device and on the other hand a prevention the function of the engine.

The motor vehicle is perfectly against in this way Theft, break-ins and damage are protected.

To switch off the anti-theft device and prevent the alarm from sounding during normal use of the vehicle triggered by the owner or user,

then it is enough if one of the electronic control center via the pulse reading or scanning device, again using the activator 3, a number of pulses communicates in such a way that this number, together with the number of pulses that have been delivered when switching on, reach the number ten as a sum.

The anti-theft device is then in the zero position returned and made completely ineffective.
