The invention relates to a fully automatic lock for doors to value left by a Combination lock and a key lock is formed.

In the case of known fully automatic locks for doors on valuables, embodiments are known in which the locking of the key lock and also the operation of the key lock are independent from the closing process of the combination lock is possible. The key lock can still be pre-locked after moving the combination lock. Regardless of this, a automatic rejection of the tumbler of the combination lock instead, which is caused by the boltwork the door is triggered. Every movement of the boltwork is transferred to the combination lock.

Another known embodiment shows a combination lock for locking the or the keyhole before, wherein the adjusting device for the discs of the combination lock is operated by an energy store. This energy store is when opened by the boltwork rechargeable and triggered by closing with the inserted key.

A disadvantage of these known embodiments is that the person you trust both when unlocking as well as must be present when closing.

The object of the invention is to create a solution to the locking of the value channel from to be able to carry out by one person without reducing safety, d. i.e., all the lock Effective functions inevitably take place. Furthermore, this closure should in case of danger be triggered as a holdover lock, so that the previously built-in top case lock is no longer necessary comes.

The problem posed is achieved, starting from fully automatic locks for doors which are formed by a combination lock and a key lock, the key lock being locked independently of the combination lock and a movement of the boltwork acting on the combination lock, in that the key lock is coupled with the locking disks for the boltwork and each locking disk in turn with an additional lever lock for the boltwork by means of connecting elements in such a way that the locking disks and the lever locks into an opening of the boltwork to-VoU automatic lock for doors through the unlocking movement of the key lock

Letting position are transferred and the locking disks by means of locking pins of the boltwork can be held in the open position independently of a closing movement of the key lock, from which the locking disks and the lever locks can be automatically transferred into the locking position.
Another feature of the invention is therein too

ao see that the boltwork by means of a transmission gear that is effective at least during its opening movement is coupled to the combination lock to reject the setting made.

The key lock can be opened and closed in opposite directions with one moved shaft to which the connecting elements are articulated to the locking disks and which carries an abutment for the lever locks.

The movement of the abutment can be opposite when the key lock is unlocked the simultaneous movement of the abutment facing, in the locked position on him be directed supporting ends of the lever locks.

A cam lever can be rotatably arranged at the bolt angle, which is in the locked position of the boltwork rests on a breakpoint; when the locking bolt is moved into the open position, a gear wheel acts and a pinion gear of the combination lock.

A connecting rod is expediently attached to the shaft, which, depending on the direction of movement, has a Knee lever lifts a rack and pinion lever that is tiltably attached to the bolt angle or on the intermediate wheel lowers.

An embodiment of the invention is shown in the drawing and described below. It shows

F i g. 1 schematically an open boltwork,
F i g. 2 a closed boltwork and

F i g. 3 and 4 each have a boltwork according to FIGS. 1 and 2, but with different adjustment means for the Combination lock.

As soon as the number secret is set, the rotary knob (not shown) of the combination lock A (see Fig. 2) can be moved. When moving, the lever 1 makes a pivoting movement according to arrow 23 and the locking disc 24 for the key lock B is released. You can now pull the key bolt out of the key lock B; the key bit is attached and the lock unlocked. As a result of this process, the shaft 2 of the key lock B moves downwards. Thus, the resistor 10 is removed from the direction of escape of the two lever locks 8, 9. The locking disks C, D , which are provided with elongated holes, receive an angular momentum via the crosshead 5 and pins on the tie rods 3, 4 and their slots 26, 27 move in the direction of escape of the locking bolts 28, 29. At the same time, the lever locks 8, 9 are raised via the two levers 6, 7. The boltwork can now be opened. All components now have the position as in FIG. 1 shown, taken ao, and in this open position of the boltwork 22, the key lock B can be locked again in the reverse order as described above.

In the event of an alarm or at the end of work, only the boltwork needs to be locked via the control center E in a known manner. When the boltwork is closed, all locking devices triggered when the key lock B is actuated are returned to their functional position as described above, as follows:

By closing the key lock B , the shaft 2 is moved upwards and brought into its locking position. The connecting element 4 follows this movement. Its pin slides upwards in the elongated hole. The locking disk D is not rotated in the process. When the boltwork is now back in the outward position, the locking pins 28, 29 move out of the slots 26, 27 of the locking disks C, D. At the same time, the lever locks 8, 9 move outward so that the free ends of these lever locks do not move are more over the abutment 10, but to the side of it; these ends can now move into the alignment of the abutment 10. By this downward movement, however, the two locking disks C, D are rotated at the same time and provide an obstacle for the locking bolts 28, 29.

As an advantageous secondary security, a lock for the boltwork is also triggered, and as follows:

As soon as the rotary knob of the combination lock A is moved, the bolt 30 moves to the left, whereby the rocker arm 31 is moved so that the locking slide 32 is raised (see FIG. 1). By lifting the stop 33 is released and the boltwork can be moved into the "open" position (see Fig. 1).

By moving the boltwork, the rack 19, which is in engagement with the intermediate gear 20 is located, partially moved and adjusted the combination lock. Notching the Toothed rack 19 takes place via lever 17 with lever 18.

The embodiment according to FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 in that the comb lever 13 rests on a holding point 12 as long as the door is closed. The comb lever 13 is rotatably attached to the locking bracket 11. If the boltwork is moved to open, then the cam lever 13 acts on the idle ring gear 15. When moving to the closed position, the same interaction is given between the idle ring gear 15 and the cam lever 13, but now the gear 14 and thus also the pinion 16 is taken, which in turn causes an adjustment of the combination lock A.
