Lock fuses, in which the key is inserted through a keyhole and to be connected to the key tongue is held in a position in which the Beard prevents it from being pulled out are already known. So one was suggested Keyhole lock with a tongue to be inserted into the keyhole common padlock to connect.

ίο This association, however, has the disadvantage that the opening of the door lock as well as that protruding from the keyhole Parts of the obstruction and the tongue are accessible to attack. It is very plentiful Space is available to destroy one or both parts with the help of a hacksaw, thus the lock to be secured is readily accessible. This deficiency is eliminated according to the invention in that the in the tongue to be inserted into the keyhole is firmly attached to a padlock, whose bracket carries a disc, which is in the final position with a recess behind puts a bunch of the key, preventing the tongue from being pulled out. Through this is achieved that under all circumstances the padlock tightly on the keyhole rests.

Another advantage of the new lock safety device is that it has both the ordinary key as well as with a keyhole lock can. The keyhole lock according to the invention also has the special It is a peculiarity that it is used for doors of different thicknesses, i.e. different locks Depth is easy to use. This object is achieved according to the invention solved that on its shaft a series of incisions are made, in which one, depending on the depth of the lock, the recess of the disc of the bracket in the Final position to prevent the tongue from being pulled out.

An embodiment of the subject matter of the invention is shown in the drawing, for example shown.

Fig. Ι shows the open padlock in a diagrammatic representation. the

Fig. 2 and 3 show the safety lock in side view and in vertical section in the closed state, in which there is the key of a previously locked door lock makes immobile.

Fig. 4 is a particular embodiment of the keyhole locker.

The lock safety device according to the invention consists of any safety padlock, which carries a metallic tongue 2 on its back r, which is appropriate

is semi-flat. The shackle 3 of this lock carries a washer 4, which is in a suitable manner is attached to the back of this bracket and a recess 5 on its underside having.

The tongue 2, which is attached in some way to the rear wall of the padlock is intended to be inserted inside a door lock. the The recess 5 provided in the disc 4 should be closed when the padlock is closed Sit astride the shaft of the key when inserting the lock Tongue 2 is placed in the door lock in front of the keyhole. This will make the turning or the key from being pulled out of the door lock.

The padlock is used as follows:

When the lock 6 of a door 7 is closed, the key 8 is in the lock left in place and turned so far that the ring of the key is horizontal (Fig. 2 and 3).

In order to make the key 8 immobile in this position, in order to prevent that it can be rotated or pulled out, the padlock according to the invention held in front of the door with the handle open and the tongue 2 in the keyhole 9 de? Door lock inserted (Fig. 2 and 3). Now all you have to do is close the padlock. For this purpose, the bracket 3 is removed from the dash-dotted line into the fully extended position (Fig. 2). The recess 5 of the disc lays then on the shaft of the key 8. as shown in Fig. 3 can be seen.

The ring 10 of the key protrudes from the padlock. In this position, the key bit prevents pull out the key while making the position of the key on the handle formed by the surface of the padlock 2 ^a support surface rotation of the key impossible.

Since the padlock is also prevented from changing its position, it follows that that the door lock cannot be opened while the padlock is closed is, and that it is impossible to reach conclusions! pull out of the door lock to to introduce another. As a result, any attempt to break the lock will made impossible. In order to be able to open the door lock, it is sufficient to close the padlock open, which releases the key and pulls the tongue 2 out of the door lock can be.

If as a result of the special shape of the door or as a result of strips or the like. The ring-shaped The handle of the key does not protrude sufficiently from the door to allow the shaft 8 of the key into the recess 5 of the padlock shackle To be able to place, the correct key can be replaced by a so-called keyhole lock 11 (Fig. 4). This is long enough to be used on doors of various thicknesses can be. It shows incisions 12 on its shaft, in one of which the disc 4 can lay down with their recess.

The tongue 2, which is attached to the back of the housing of the padlock, can, instead of being firmly connected to it, also be attached to it by means of a hinge, so that it can be folded up to the padlock. Instead, it can also be detachable so that you can remove them at will.

This tongue can also be attached to the arched, am Bracket attached disc can be attached. In this case the padlock will be used of course, used with the hanger down, and it is closed by flipping it of the housing on the bracket, which is immovable by the engagement of the tongue 2 in the door lock is held.
