Embodiment Construction

[0041] figure 1 A part of a double-toothed key 7 is shown, which consists of a section 11 of the key shaft 10 with a tooth 12 coupled thereto at the end 43 of the shaft 10 . Some of the several key stages of teeth 12 are identified with reference numerals 13 , 14 , 18 , 56 , 57 and 58 . Here, the key level 14 protrudes maximally on the side 59 of the tooth 12 , while the key level 13 protrudes maximally on the opposite side 60 . In the exemplary embodiment, the distance between the most protruding key levels 13 and 14 is between 9.5 mm and 11 mm. In other words, the diameter of the key bit 12 , with regard to the correspondingly largest protruding key stages (here key stages 13 and 14 ), is in the range of dimensions which are advantageous with respect to stability criteria on the one hand and safety criteria on the other hand . This diameter is additionally indicated with reference numerals 42 , 42 ′.

Abstract

A key (7) serves for actuating a lock and has a grip, a shank (10) and a key bit (12), on which is arranged the coding of the key (7) in the form of key steps (13, 14, 18). The key bit (12) has key steps (13, 14, 18) on either side, wherein the diameter of their key bit (12), in relation to the key steps (13, 14), which project to the maximum extent in each case, is between 9,5 mm and 11 mm. A lock (1) for such keys (7), having a plurality of tumblers (24) arranged in a lock housing (2), has a rotatably mounted follower (3) which can be actuated via the key (7). This follower (3) is designed in the form of a multifunctional component, as a structural unit for repositioning the tumblers (24) and / or for controlling the locking function.

Description

technical field [0001] The invention relates to a safety lock to be actuated with a double-tooth key, which has a plurality of swivel arms arranged in a lock housing. [0002] Furthermore, the invention relates to a key for actuating a safety lock with a handle, a handle and a key bit, on which the code of the key in the form of key stages is arranged. Background technique [0003] Safety locks for eg installation in safes are known in the most different variants. A weak point of several known locks here is the relatively simple possibility of accessing the inside of the lock with a suitable tool through an opening in the side of the lock in order to actuate the pivot arm. It is therefore expedient to keep the lock opening as small as possible, which dictates that the key must be constructed equally small. With hitherto known locks, in addition to the key for the locking function of the lock itself, it is also necessary to provide an additional key for activating the adjus...
