Vehicle theft protection Description

The invention relates to an anti-theft device for vehicles, in particular for motor vehicles, according to the generic term of the protection claim Securing alarm systems and immobilizers for vehicles are generally known.

However, vehicle thefts that are not carried out by "short-circuiting" the ignition when there is no immobilizer, but by the entire vehicle being stolen by loading it onto a truck using hydraulics, continue to cause considerable problems.

The vehicle theft protection presented here offers a secure defense against gangs of thieves, especially for high-quality vehicles. A very advantageous theft protection system is proposed here, which is not only technically easy to implement, but also does not place too high demands in terms of cost and maintenance.

A contact bridge is set up between the vehicle and the ground on which it is standing, which is broken if the vehicle is lifted or moved, which triggers not only an alarm without any delay, but also smoke development to attract special attention.

Instead of smoke development, a predefined radio alarm could also be used to locate the vehicle at risk or to arrest the thieves.

The vehicle anti-theft device is also suitable for any terrain, as a joint compensates for unevenness such as rocks, slopes or inclines and the sensors housed in the base cover are always in contact with the parking surface. Corrosion-free aluminum material, for example, would enable a long service life, and in addition to the well-known hard-wearing elastomers and thermoplastics, a number of metals would also be available.

A monitor system shows the contact hood's contact point, so that not only is the area safe, but also the safety is ensured, for example, that animal injuries are avoided. The circumference of the contact hood also takes into account the possibility of slipping into a drain opening or openings in the sewer cover.

Claims (3)

1.) Vehicle theft protection, characterized in that, for example in passenger vehicles, a telescopic pushing and lifting device (3) is attached to the bulkhead (1) or underneath the vehicle floor (2), which is extended and retracted by means of a motor, electric power or manually operated (4). The pushing and lifting device, which is designed as a shaft ( 3 ), is provided with a joint at the lower end ( 5 ) to which a hood serves as a contact surface for the ground ( 6 ), thus forming the closure to the ground or soil and is structurally connected following the joint ( 5 ). 2.) Vehicle anti-theft protection, characterized in that the corrosion-resistant telescopic system (3), which is usually operated mechanically, comes to a standstill by means of an infrared, laser or ultrasound distance measurement, after the hood (6) has been pressed against the ground, which is equipped with sensors, by means of a corresponding touch pressure. Depending on the requirements of the measuring device, the hood base (7) is open or closed. Until the stop point is reached, the process of extending and retracting the telescopic system is monitored by means of a monitor system (8), the camera (9) of which is installed under the hood, for example for the observation function, in a wired or wireless manner. In the event of a technical emergency, a winch ( 10 ) ensures that the telescope can be operated manually. 3. ) Vehicle theft protection according to claims 1 and 2, since-" ¹ characterized in that the motion detectors (sensors), both with the immobilizer in the vehicle and installed separately, trigger an alarm for all horizontal and vertical changes in movement after the vehicle has been switched off, which alarm can be combined with an alarm system if no pre-programmed alarm has been entered.
