Description

Immobilizer for motor vehicles

The invention relates to an immobilizer for motor vehicles, in particular a mechanical immobilizer in the event of irregularities in motor vehicles in stationary traffic.

Different types of immobilizers for motor vehicles are known for securing and protecting, in particular for theft protection. The main safeguards are electronic additional parts, devices or small devices that prevent or indicate unauthorized start-up or theft within the vehicle. The ignition, steering, gearbox, brakes or vehicle doors are blocked in conjunction with locks. However, these safeguards are mostly used by the vehicle owner or operator, which is often a complicated or expensive installation device.

A mechanical immobilizer that can be attached to the vehicle from the outside is known from a company catalog. It is to be clamped to the wheel rims of a motor vehicle wheel like a metal clamp and, by means of a two-point lock, blocks the wheel when starting or continuing. However, this lock can be released again by simple mechanical handling and does not offer reliable security against unauthorized use of the vehicle.

REPLACEMENT B π (RULE 26)

In order to ensure that motor vehicles are kept safe in the event of an offense in traffic, regulatory authorities have so far mostly been forced to notify drivers of their offenses by towing their motor vehicle after paying a warning.

Other reliable safeguards for motor vehicles behaving improperly in stationary traffic through certain blocking measures are not known.

Several immobilizers for motor vehicles are also known from the patent literature. According to the utility model DE 296 04 852 an anti-theft device for motor vehicles, especially for cars, is known, which is used for two wheels on one axle. It consists of a base plate with a trough, side plates, a frame with a bolt-spring mechanism and switch cams that can be folded up as a ramp extension for an alarm system that is inaccessible when the fuse is in the locked state.

The car wheel is positioned in the sheet steel trough of the floor plate so that the floor is inaccessibly covered by the tread of the wheel. When the wheel is moved unauthorized, the tire over the bolt

Alarm device activated.

The pure alarm security system, which can only be unlocked by the driver of the vehicle, has proven to be disadvantageous with this security. Another known locking system according to DE-OS 30 30 308 includes a collapsible vehicle securing clip in which a frame-shaped part is attached to a vehicle tire in such a way that it can be folded down

Gripping arms grip the vehicle wheel diagonally. The rotatably mounted Gripping arms of the frame rest on the tire barrel or enclose the wheel flanks with their bow-shaped ends.

The frame and gripper arm ends have a specific profile with a brake wedge effect between the vehicle wheel and the road and a pressure effect on the wheel covers.

The frame can be locked with a padlock with the gripper arms. Disadvantages of this security device in the event of vehicle theft are the relatively easy to open locking system and the uncomplicated disassembly of the gripper system.

Furthermore, according to DE 43 04 971, a wheel lock for establishing an inseparable connection between an outer vehicle wheel and a body part is known. At the end of a traverse, a gripper is attached, which is introduced into an opening or recess in a vehicle wheel. A bracket attached to the vehicle body receives a lockable tensioning device and a connecting bar which also engages in the receiving device of the crossbar.

The connecting bolt with the crossbar can be locked with a pawl. The gripper and pick-up device are connected by clamping screws.

This wheel lock is light, handy, quick to assemble in city traffic, but it is disadvantageously insufficiently robust and complex in terms of safety technology and is therefore easy to break open with the appropriate tools. The invention therefore has for its object to develop an immobilizer for motor vehicles in the area of stationary traffic, which has an uncomplicated mechanical structure, visible from the outside on the vehicle with little effort and can be removed and with a reliable security and Alaπtuäystem against unauthorized persons Vehicle use is equipped.

The present object of the invention is achieved in that the immobilizer for motor vehicles in stationary traffic, which is constructed as a mechanical tensioning device, is characterized in that it can be fitted as an automatic multi-point lock on motor vehicle wheels and consists of several functional groups with interacting components and one There is a safety locking, locking and separating mechanism.

According to the invention, several clamping arms, each equipped with an eccentric claw, are connected to several push arms of a multi-arm base body, on which, under a cover, the locking, locking and separating mechanism actuates a gear drive for tightening and releasing the push arms and the clamping arms via connecting and separating elements or a rotary handle with linkage .

The immobilizer is characterized in that it preferably consists of three clamping arms, each with an eccentric claw, and two clamping arms each have an adjustable locking block, the Sp.ann.arme by three push arms via compression springs and a gear drive in the six-armed base body with the linkage of the rotary handle and are connected to the locking, locking and disconnecting mechanism. Tensioning and pushing arms can be moved with the linkage by means of the gearwheel drive using the rotary handle and locked and locked with the locking, locking and separating mechanism using the safety lock. Locking, locking and separating mechanisms consist of a connecting element, trimming element and lever. When the immobilizer according to the invention is locked, the connection between the rotary handle and the gear drive is interrupted, since as an additional security the applied and locked device is still separated mechanically by disengaging the connecting element (lock position: locking / disconnecting) by means of a separating element between the rotary handle with the linkage and the gear drive, so that a violent opening of the device via the rotary handle to the drive is not possible.

In operation, the device according to the invention has the following advantages:

- Quick and easy application of this device to the respective vehicle by attaching the three fastening arms, - Choice of the direction of rotation (opening or closing) by means of the safety lock via the control lever for the locking and locking mechanism, - Turning the rotary handle to the right causes the device to be pulled together and pressed on the tire tread, - turning the key all the way to the right causes locking.

The device is now mechanically locked and the rotary handle no longer has a mechanical connection to the locking mechanism (turning the handle free);

- The key can only be removed afterwards; - An automatic retensioning of the applied device when changing the air pressure in the tire is possible.

In the event of theft or unauthorized driving away of the motor vehicle, a violent pulling off is prevented by the holding elements, which stand up when there is a train and, depending on the effect of the force, increase the pressure on the tires. Destroying the lock would also have no effect on opening, since the lock is operated using a transverse linkage. The linkage cannot be operated from the outside and falls off when the lock is destroyed. The base body has a base plate on its underside, which is simultaneously designed as a cover plate for wheel bolts, wheel nuts and valve insert of the motor vehicle wheel, so that it is not possible to remove the wheel when the immobilizer is applied. The lower holder arms have starting blocks against driving with the device, which make driving and steering impossible.

The immobilizer according to the invention can be used for different standard sizes of motor vehicle tires.

The invention is explained below using several exemplary embodiments with reference to the present drawings.

In the drawings, FIGS. 1-7 represent embodiments and details of the solution according to the invention.

Accessories,

4: the schematic structure of an eccentric claw,

5: a two-arm adjustable immobilizer,

6: a one-arm adjustable immobilizer,

Fig. 7: the top view and side view of a three-arm immobilizer in operation.

The mechanical immobilizer according to the invention (FIGS. 1-3) consists of three clamping arms 1 and 2 with retaining elements attached at their ends in the form of eccentric claws 15 which engage as multi-point locks in the tread of the tires of motor vehicle wheels. As an independent mechanical tensioning device, the immobilizer can be fitted to vehicle wheels from the outside, preferably to the front wheel of the driver's side. The two lower clamping arms 2 are each equipped with an adjustable wheel lock in the form of a start-up block 16, so that driving and steering the vehicle when the immobilizer is applied is not possible.

The tensioning arms 1 and 2 are connected to three thrust arms 3, which are mechanically connected and interact with the locking, locking and disconnecting mechanism 7 via the gear drive 5 arranged in a multi-arm base body, preferably a six-arm base body 4. The push arms 3 can be adjusted in the desired position by means of a rotary handle 10 via a linkage and the gear drive 5 with racks and gear and by means of a security lock 9 Keys can be locked and locked in this position via the locking, locking and separating mechanism 7.

The locking, locking and separating mechanism 7 is arranged on the base body 4 under a cover 8, preferably the security lock 9 is attached to the side of the cover 8. Further actuating elements, preferably a connecting element 11, a separating element 12 and a lever 13 are arranged via a connecting axis 24 and locking plate 25 between the rotary handle 10 and the gear drive 5 so that in the "locking" position the rotary handle 10 is mechanically separated from the actuating elements and the Gear drive 5. The connection between the rotary handle 10, the connecting element 11 and the gear drive 5 and thus the locking mechanism 7 is interrupted by means of a separating element 12, and it is not possible to move the push and tension arms 1, 2, 3 to open the immobilizer.

The connecting element 11, which creates the mechanical connection between the locking, locking and separating mechanism 7 with the gear drive 5, causes the push arms with racks 3 to be pulled out of the base body 4 - or into the base body 4 and thus the tensioning arms 1 and 2 tighten or loosen on the wheel.

Pressure springs 14, which are arranged between thrust arms 3 and gear drive 5 in the base body 4, cause the tensioning arms 1, 2 to be automatically drawn together and pressed onto the tread of the tire. The base body 4 has on its underside a base plate 6, which is designed in size so that it serves as a cover plate for the wheel bolts and wheel nuts as well as for the valve insert, which means that when the lock is applied, dismantling of the motor vehicle wheel or deflating the air does not is possible.

The eccentric claws 15 (Fig. 4) prevent the entire immobilizer from being forcefully pulled off the wheel, since they lift up vertically when there is a train and increase the pressure on the tires. If, when the tire pressure is reduced, the safety lock 9 of the applied lock is in the “locking position”, the compression springs 14 installed between the base body 4 and push arms 3 provide a positive connection between the tensioning arms 1, 2 and thus the eccentric claws 15 and the blocking blocks 16 on the Guaranteed tread of the tire.

The immobilizer according to the invention can be used for different standard sizes of motor vehicle tires, preferably for the dimensions from 420 to 760 mm.

5 shows a two-arm adjustable version of an immobilizer. A four-armed base body 4 has two thrust arms 3 with two clamping arms 1 with eccentric claws 15. The blocking blocks 16 are fastened to an adjustable base frame 23

Fig. 6 shows a one-arm adjustable immobilizer with a tension arm 1 with eccentric claw 15 and a push arm 3, in which the two blocking blocks 16 for the wheel tires are also attached to an adjustable base frame 23.

Locking and separating mechanisms are constructed for these one and two arm versions as described for the three arm version. Furthermore, it is possible that the immobilizer according to the invention has one or more different electronic additional devices for special displays.

Fig. 3 shows different mounting variants for these electronic additional devices, which are made possible by integrating electronic contacts in the basic version.

By installing an acoustic output device 17, when the immobilizer is applied, when the blocked vehicle starts up, an electronic vibration signal is generated by an acoustic signal in the form of a horn or piezo signal or the like.

A permanently mountable radio add-on device 18 for securing the location by radio can advantageously also be arranged on this thrust arm 3 of the six-arm base body 4 in order to ensure the transmission of location and other data to a control center.

When the immobilizer is applied, an optical display device 21 can activate a visual display, preferably a flashing light, or a time display device 20 can determine an electronic time recording of the irregularity in stationary traffic, for example the duration of incorrect parking. A plug 19 integrated in the base body 4 enables the connection of further control devices, for example by transferring and evaluating time, location and other data to an external laptop through an attachable multipin plug for data transmission or remote data transmission. The additional devices can be mounted individually or in combination with the special electronics in or on the base body 4 and can be expanded at any time, the power supply being provided by a built-in accumulator 22.
