Problems solved by technology

In the transition between the locking element rod and the locking element head, the locking element head can have a collar-like formation, but this makes the production of the locking element considerably more difficult.
[0005] It is particularly disadvantageous that specially formed locking elements protected against manipulation must be expensively produced, for example by casting, stamping, shaping or the like
The handling of the guide surfaces for the guidance of the locking element in the opening at the front of the lock housing is made difficult by the special dimensions of the shaped part for forming the protection against manipulation, since these guide surfaces are no longer completely flat

Embodiment Construction

[0030] figure 1 An exemplary embodiment of the protective device according to the invention is shown. Shown is a locking element 11 which is designed as a latch with a rectangular cross-section and is guided longitudinally movable in an opening at the front of the lock housing of the lock. The locking element 11 has a locking element rod 16 to which a locking element head 17 is coupled. The locking element rod 16 forms a part of the locking element 11 which remains inside the lock both in the open position and in the closed position of the locking element 11 , ie behind the lock housing front. Conversely, when the locking element 11 is moved into the locking position for locking eg a door, the locking element head 17 protrudes from the front of the lock housing of the lock.

[0031] According to the invention, the protective element 14 is arranged in the region of the transition from the locking element shaft 16 to the locking element head 17 . The protective element 14 is ...

Abstract

The invention relates to a device for safeguarding a lock (10) against manipulation, which lock (10) has at least one locking element (11) which, through an opening (12) in a lock case front (13) of the lock (10), can be moved out of the lock (10) into a locking position and back into the lock (10) into an open position. According to the invention, it is provided that at least one safeguarding element (14) is arranged on the locking element (11), and this therefore means that a gap (15) formed between the locking element (11) and the opening (12) is covered over.

Description

technical field [0001] The invention relates to a protection device against operation of a lock for a lock having at least one locking element which can be moved out of the lock through an opening in the front part (Stulp) of the lock casing of the lock to In the locked position and move back into the lock into the open position. Background technique [0002] Locks for doors, gates, windows and the like can be actuated by acting on a locking mechanism inside the lock with an operating element. The operator can be introduced into the lock through the opening in the front of the lock housing, since a gap is formed between the locking element and the opening. If a spring wire or preferably a spring leaf is used as the operating element, then the operating element can be used to act easily on the push-back locking of the locking element, especially on the brake, especially in the case of a door that is not turned over. On the moving pin (Zuhaltung). If the push-back locking o...
