Definitions

the innovation relates to a lock protection device according to the preamble of protection claim 1.
lock protection devices which are intended to prevent a lock cylinder from breaking off. These consist of a metal body which surrounds a part of the locking cylinder, namely the part which protrudes from the door plate, and within this body a plate is also made of metal, which has a slot for inserting the key into the lock. This plate is rotatably arranged.
DE-OS 25 57 151 may be mentioned as an example of this.
a rotatable cover, which is intended to prevent the lock cylinder from breaking off, is known from DE-OS 19 26 519.
the innovation is therefore based on the task of creating a lock protection device which, on the one hand, makes it difficult to break open the lock or pull out the core and, on the other hand, enables the key to be inserted into the cylinder core in order to carry out the closing movement.
this object is achieved in that the plate arranged in the hard metal body surrounding the lock cylinder can be displaced axially within the recess of this hard metal body by stops.
the plate can be under an axial spring pressure, so that it always inevitably bears against the cylinder core or the housing during its axial displacement within the recess, thus avoiding any play between this plate and the core, so that a secure insertion of the key is guaranteed.
the plate in the hard metal body can be screwed into the hard metal body by means of an internal thread on the recess of the hard metal body or an external thread on the plate, so that the plate is also in contact with the cylinder core. Even after a corresponding fixation of the plate from the inside, which prevents further screwing in or unscrewing, the necessary transition from the plate into the core for the key is then possible, and thus finally a correct closing.
a schematic cross section and a front view through the lock protection device are shown in the figures.
the lock protection device consists of a metal body 1 surrounding the lock cylinder, which has a recess 3.
the plate 2 which is also made of metal, is rotatably arranged in this recess 3 and is axially displaceable, the displacement of which is limited by an outer stop 4 and an inner stop 5.
the metal body 1 is applied from the outside to the lock cylinder and fastened there, in such a way that from the inside the cylinder core presses against the plate 2, which in turn is under the action of a spring 6 and is thus pressed against the core. This ensures that there is no play between the plate and the core and a secure insertion of the key is guaranteed.
the metal body 1 is also shown in section and in the recess 3 there is the plate, which is provided here with the reference number 7.
This plate has an external thread 8 while the recess of the metal body has an internal thread 9.
the threaded plate has on its front side a rotatable second plate 7a which cannot be displaced in the axial direction relative to it.
the connection between threaded plate 7 and plate 7a can be done, for example, by flanging 7b. In this way, the threaded plate 7 with plate 7a is axially displaceable within the recess of the metal body 1 and can thus be pressed against the cylinder core.
An external stop 4 is also provided here, which prevents the plate from being unscrewed.
