DE1063487B - Device for securing against unauthorized opening of locked motor vehicle doors - Google Patents

Description

The object of the invention is related to door locks for motor vehicles in which the outside handle of the lock can be decoupled from the lock gear.

In the interior of the car door, the upper part of a rod is often visible on the window sill, leading to the Door lock leads and when depressed the decoupling of the outside handle from the gearbox of the lock indicates. Pressing this bar down can also be used to secure the door against unintentional opening serve the door while driving.

The uncoupling device between the outer door handle and the lock latch can in many cases by the Inserting a key into a lock cylinder associated with the lock mechanism, can be canceled again by turning the key, so that the operating rod for the uncoupling lifts out of its contraction again and becomes visible in the window. By becoming visible the decoupling rod, the motor vehicle owner knows that the door lock is not secured and that the outer door handle is also not disengaged from the lock gear.

If the vehicle owner leaves his vehicle after he has also locked the other doors, he must he, if he wants to secure the car door next to the driver's seat against unauthorized opening, the uncoupling rod press down. The lock latch is located after the uncoupling rod has been pressed down in freewheel, d. i.e. you can lock the door without the coupling rod lifting up again, in such a way that it can no longer be opened by means of the outer door handle.

That the decoupling of the outside handle compared to a detection of the outside handle in car door locks Bringing benefits is well known. If the outside handle is detected, it can The lock was destroyed by force and the car door opened.

But also when the outside handle is uncoupled, with the uncoupling through the one on the window sill above mentioned uncoupling bar is identified, it has been shown that car thefts by opening the door have become possible.

The aim here is not to describe the way in which it has become possible to remove the uncoupling rod to lift out of their position disengaging the outside handle from the lock mechanism. Just so much is here mentions that by means of special tricks it was possible to remove the depressed uncoupling rod from the outside to lift it out of its recessed position without using the door lock for this purpose. The construction the door locks in the case of the known devices are carried out in such a way that even when the

When the uncoupling bar is pressed, the car doors can be opened by operating the inner door handles, so that the occupants always have the opportunity to leave the vehicle.

The object of the invention is, in motor vehicles, in which by pressing down the uncoupling rod the outside handle is uncoupled from the lock gear, pulling out the uncoupling rod again to prevent from their recessed position from the outside through the locked door.

To solve the problem, the invention proposes a device for securing against unauthorized persons Opening of locked motor vehicle doors by means of a decoupling rod arranged in the window sill before, by decoupling the outer door handle from the lock mechanism in the depressed position is and wherein the uncoupling position of the rod by actuating a cylinder lock of can be canceled outside and in which the uncoupling rod consists of an upper part and a lower part and the division of the rod takes place in such a way that in the uncoupling position only the lower part with the lock gear is inevitably coupled.

In this way, the trick described above, namely the upper part of the coupling rod, can be performed Pull out its recessed position and with it the coupling to the outer door handle and lock gear can no longer be carried out. It is possible to pull out the upper part, but the Coupling does not take place then because there is no connection between the upper and the lower part consists. The coupling of the outer door handle with the

Claims (5)

1 Lock transmission can only take place if the cylinder lock engages the two parts with the appropriate key. The drawing shows an embodiment of the invention schematically. In the drawing, only the upper part of the uncoupling rod and part of the lower rod part, which leads to the lock mechanism, are shown. With 6 the window sill of the car door is referred to. The guide 5 for the upper part 1 of the uncoupling rod sits on the window sill. The lower part is labeled 2. It is guided through the guide sleeve 3. The guide sleeve 3 is in positive connection with the upper part 1. In addition, a disk 4 sits on the connecting piece between the upper part 1 and the guide sleeve 3. The mode of operation is as follows: If you want to decouple the outer door handle from the lock gear, you press the upper part 1 of the Uncoupling rod. As a result, the disk 4 and the guide sleeve 3 move with it downwards in the direction of the arrow. The lower part 2 of the uncoupling rod is thereby depressed and then causes the outer door handle to be uncoupled from the lock mechanism. It is within the scope of the invention to arrange other lever linkages between the upper part 1 and the lower part 2 of the uncoupling rod if one wants to arrange the upper part 1 at any other point in the vehicle interior or on the window sill. It is also within the scope of the invention to arrange a spring on the lower part 2 which presses against the upper edge of the guide sleeve 3. This has the effect that, despite the uncoupling of the outer door handle from the lock mechanism, it is not possible to determine from the outside in which way the uncoupling has been carried out, since the upper part 1 moves back over the guide 5 into its normal position. It is also within the scope of the invention, by pressing down the upper part 1 z. B. to switch on an electromagnet, which changes part 2 of the uncoupling rod into its locking position-487. In this case, too, it cannot be seen from the outside in which way the outer door handle has been decoupled from the lock mechanism. Patent chef: 1. A device for securing against unauthorized opening of locked motor vehicle doors by means of a decoupling rod arranged in the window sill, through which the outer door handle is decoupled from the lock gear in the depressed position, the decoupling position of the rod being reversible by actuating a cylinder lock from the outside, characterized in that the decoupling rod consists of an upper part (1) and a lower part (2) and the subdivision of the rod takes place in such a way that in the uncoupling position only the lower part (2) is necessarily coupled to the lock mechanism. 2. Apparatus according to claim 1, characterized in that a spring is inserted between the lower part (2) of the uncoupling rod and the upper part of the guide sleeve (3) which lifts the upper part (1) back into the normal position after uncoupling. 3. Apparatus according to claim 1, characterized in that a lever transmission is interposed between the parts (1 and 2) of the uncoupling rod. 4. Apparatus according to claim 1, characterized in that an electromagnet is switched on by pressing down the upper part (1 ) which brings the part (2) of the uncoupling rod into its uncoupling position. 5. Device according to one of the claims, characterized in that the coupling between External handle and lock mechanism are carried out by the corresponding parts of a lock cylinder, which is operated by means of a key in a known manner.
