DE620053C - Key for locks with protector tumblers - Google Patents

Description

To guarantee the complete security of a lock To be able to do this, it is not enough to simply have an unlockable guard locking system with different Manufacture keys for each individual lock, but it has long been recognized, that a special meaning the actual prevention of molding and replication of the keys comes to.

To achieve these goals, the beard shapes became the key with hollows and Oblique slots provided; multi-bearded keys were created, as well Keys in which the inherently rigid part of the beard when the key is inserted into the Castle was changed in its location.

However, all of these previously known devices are not sufficient to simulate Keys to prevent effectively.

The present invention, however, fully meets these requirements. With the new key, the individual key steps can be turned on Key shaft arranged. Your original equality when introducing the Key is changed like a fan when turning the same in cooperation with the tumblers of the lock, in a Way that the key due to its special shape in this position with known Funds cannot be molded. He is also not in this position of the beard lamellae each other insertable or removable in the lock.

The execution can be done with one or more beards. The accompanying drawing illustrates an implementation in the double-bit system. In picture I to VI the key bit lamellas 11 to 16 are shown. The same can be different in the step heights. Each of these different types of training is also given one of the various recesses a ^x to α ⁶ , which laterally widen the central circular opening. Furthermore, the beard lamellae carry 4-5 pins & ¹ to b ^s , which each engage in corresponding recesses c ¹ to c ^{6 of} the beard when the latter are aligned in one plane. Figure VII shows spacer washers, which also have keyways a ¹ . Figure XI shows the whisker d with wedge d ¹ and shoulder d ² . Figure VIII shows the view of the key with the bit mounted, Figure IX the cross-section with the bit in the working position.

The beard lamellae b are lined up alternately with the intermediate layers ζ on the beard mandrel d. The wedge d ^{1 of} the beard mandrel lies in the differently designed recesses a ¹ to a "of the lamellas. The beard mandrel d is inserted into the key shaft e (Fig. VIII), and both are rigidly connected to one another d ^2. Fig. IX shows the position of the

Beard lamellae in rest position. The wedge lies in this with all slats on the left side of the recess a ¹ to α ⁶ . Image X, on the other hand, shows the position of the beard lamellae in the working position relative to the tumblers. Here the slats are shifted against each other like a fan, and the wedge rests on the right-hand side of the recesses. Since this position of the key bit lamellas means that the

ίο would not allow the key, pins b ^l to - b ⁵ and recesses c ¹ to c ⁶ are alternately attached to the slats, which means that when the key is turned back, the slats are inevitably in the basic position (BiIdIX).

Claims (3)

Patent claims: i. Keys for locks with protector tumblers, characterized in that the beard from a number of rotatably mounted at certain angles on the key pin Lamellae (1), which when hitting the tumblers before -Lifting the latter twist out of their rectified position so that they are in the open position of the key Form a beard shape that prevents the key from being removed and molded. 2. Key according to claim 1, characterized in that during the closing process the beard lamellae are returned to their rectified basic ^{position by their rotational movement limiting stop pins (δ 1} to b ^e ). 3. Key according to claim 1 and 2, characterized characterized in that as a stop for the arrangement of the beard lamellae in their position intended for the opening a wedge provided on the whisker is used. 1 sheet of drawings
