Definitions

• the present invention relates to a protective device for a lock against manipulation of the lock, which lock has at least one locking element, which can be moved out through an opening in a Stülp of the lock in a closed position from the lock and moved back into an open position in the castle.
• Locks for doors, gates, windows and the like can be manipulated by acting with a manipulation object on the Schffyme- mechanism within the castle.
• the manipulation object can be inserted into the lock through the opening in the cover, since a gap is formed between the locking element and the opening.
• a spring wire or preferably a spring plate is used as the manipulation object, the non-rebated doors can easily be acted upon by the manipulation object on the reverse slide lock of the blocking element, in particular on the tumbler. If the push-back lock of the blocking element, for example a lock bolt or a lock latch, is released, this can be returned to the opening position of the lock, and a door can be passed without authorization.
• the gap between the locking element and the opening is created in particular by the fact that a more or less large clearance between the locking element and the opening is required.
• the opening in Stülp often serves as a guide of the movable locking element, which may for example represent a bolt or a trap. It also resembles the clearance fit manufacturing tolerances of the individual components, whereby the gap can reach a lateral dimension of, for example, 0.5 mm.
• a lateral dimension for example, 0.5 mm.
• Higher-quality locks have locking elements which are designed geometrically such that the gap between the blocking element and the opening can be at least partially covered.
• a blocking element may have a blocking element shaft with a smaller cross section and a blocking element head with a larger cross section.
• the blocking element head can have a kind of collar-like formation, which, however, makes the production of the blocking element considerably more difficult.
• the locking elements formed in particular with a manipulation protection have to be manufactured consuming, for example by casting, embossing, forming or the like.
• the processing of the guide surfaces, which serve to guide the blocking element in the opening of the Stulpes is made more difficult by formations to form a manipulation protection, as they are no longer flat over the entire surface.
• a reworking is usually required because only so sufficiently smooth and dimensionally accurate guide surfaces on the locking element can be produced. The reworking is used for high quality stainless steel bars at the same time for surface refinement, z. B. by grinding, satin, polish and the like.
• the invention includes the technical teaching that at least one protective element is arranged on the blocking element, so that a gap formed between the blocking element and the opening is covered.
• a protective element is arranged on the blocking element, then the gap formed between the blocking element and the opening is covered to such an extent that a manipulation object can no longer be introduced into the castle through the gap. Attempting to move a manipulation object through the gap will strike the protective element and it will be impossible to move the manipulative object further into the interior of the lock.
• the protective element is designed according to the invention as a single component which can be arranged on the blocking element. Consequently, the locking element can be made of simple flat materials, wherein the reworking of the guide surfaces can be done by simple machining operations, since they are flat over the entire surface, since no protrusions to form a tamper protection could interfere with a flat machining.
• the blocking element may have a blocking element shaft and a blocking element head, wherein the protective element is arranged in the region of the transition from the blocking element shaft to the blocking element head on the blocking element.
• the locking element head forms the part of the locking element which can protrude from the turnout of the lock when the locking element is moved into the closed position.
• the blocking element shaft forms the part of the blocking element which points in the direction of the inside of the lock and on which the locking mechanism engages, in order to control the movement between the closed position and the open position in the blocking element initiate.
• the protective element can be arranged at the location on the blocking element, at which the blocking element shaft merges into the blocking element head.
• This transition point is located approximately at the back of the Stulpes when the blocking element is moved out of the lock in the closed position. Consequently, the protective element is also located on the back of the cover, and access to the inside of the lock through the gap is interrupted immediately behind the Stülp when the locking element for taking the closed position is moved out of the lock.
• the blocking element shaft can have a smaller cross section than the blocking element head and form a blocking element edge in the region of the transition from the blocking element shaft to the blocking element head, the protective element being brought into contact with the blocking element edge from the direction of the blocking element shaft.
• the cross section of the blocking element may correspond to a rectangular cross section, and the rectangular cross section of the locking element head has larger edge lengths than the edge lengths of the rectangular cross section of the blocking element shaft. This results in a blocking element edge with an edge surface which extends transversely to the direction of movement of the blocking element. against this edge surface, the protective element can be brought to bear.
• the protective element may have a passage through which the blocking element and in particular the blocking element shaft is guided.
• the protective element can simulate the aspect ratio of the edge lengths of the rectangular cross section of the blocking element, and a protective element attached to the blocking element forms a collar which surrounds the cross section of the blocking element.
• the protective element at least partially and preferably completely surround the blocking element, so that the gap between the blocking element and the opening is completely covered. consequently No manipulation object can be introduced into the gap between the blocking element and the opening in the cover from either side.
• the protective element in blocking elements which have a rectangular basic cross-section, the protective element can be designed so that the locking element is completely covered.
• Such a protective element has a passage through which the blocking element consequently extends. Special protection achieves a protective element, which is arranged on the side of the blocking element, which points in the direction of a free door gap.
• the protective element can be latched, clipped, screwed, welded, soldered, pressed on and / or pressed onto the blocking element by means of plastic injection molding on the blocking element.
• the protective element may be made of a hardened steel.
• the protective element may be made of the same material as the blocking element itself.
• the protective element may be made of a plastic material which is injection-molded onto the blocking element.
• the blocking element can have receiving geometries in order to form a geometrical positive connection between the blocking element and the molded plastic protective element.
• the protective element can be mechanically attached to the blocking element, wherein the connecting structure between the protective element and the blocking element is made sufficiently resilient in order to avoid that the protective element can be released from its position on the blocking element by means of the manipulation object.
• the protective element may consist of a Sheet metal material can be produced by stamping-bending process, or the protective element is produced by means of a metal die-casting process.
• the blocking element of the lock with the protective device according to the invention can be embodied in various ways.
• the blocking element can be designed as a lock bolt and / or as a latch of the lock.
• a lock regularly has a lock bolt, which is moved via a lock cylinder between the locking position protruding from the lock and the opening position retracted into the lock. Consequently, the lock bolt is used to lock a door, without this can only be opened by a door handle.
• the blocking element can also be designed as a lap trap, which can be moved according to the regular design of a lock by means of a handle between the closed position and the open position, whereby a movement of the lock latch can in principle also take place via a lock cylinder.
• Lock traps are usually biased by a spring element in the closed position, further locks are known, which lock the lock latch in the closed position to lock the lock by means of a lock cylinder by a reverse slide lock the lock latch is activated.
• the protective element according to the invention can be arranged independently of the embodiment of the blocking element as a lock bolt or as a lock latch on this.
• the blocking element can be moved linearly in the opening in the Stülp, rotationally moved or moved along a trajectory.
• Linearly moving blocking elements usually have a rectangular cross-section and have an elongated extension which is subdivided into the blocking element shaft in the inner region of the lock and the blocking element head, which can be moved out of the step in the blocking position.

• the shell-like protective elements form a collar, which surrounds the part of the blocking element in a collar shape, which protrudes in the closed position from the Stülp of the castle.
• the blocking element may have an axle which extends in the pivot axis and forms the mechanical receptacle of the locking element designed as a pivot bolt.
• the axle bolts can be designed in such a way that the protective elements resting laterally on the blocking element form a constructional unit with the blocking element, and can only be detached therefrom by overcoming considerable mechanical forces.
• the blocking element can be designed as a pivot bolt with a pivot bolt back, wherein the protective element is designed as an insertion element and is arranged on the pivot bolt back.
• the insertion element may preferably be cohesively or positively arranged on the blocking element, and extend only over the pivot bolt back or the insertion element surrounds the pivot bolt at least also in the lateral direction.
• the protective element can cooperate with an electrical switching means, so that at least one detection of the closing position of the blocking element is made possible by a control unit.
• the electrical switching means may for example form a switch, preferably a microswitch, with which the protective element cooperates mechanically to activate the electrical switching means. For example, information can thus be transmitted to the control unit as to whether the blocking element is in the closed position or in the open position.
