DE548246C - Door security, especially for safes and vaults - Google Patents

Description

The known lock fuses for value containers are mainly limited to the careful execution of the locking devices and the securing of the keyholes.

Burglars can change the position of the locking devices from the position of a keyhole easily recognize and initiate the attack accordingly. Even if it was attempted in this way Opening the safe is extremely difficult, if not impossible at all, so damage is caused by such attacks and as a result expensive repairs required.

This deficiency is now eliminated by the present invention in that the main lock, which has to trigger the blocking of the main bolt, completely out of the area by means of a special ao changeover lock its interaction with the blocking of the main bolt and the one belonging to it Keyhole is brought.

This lock safety device is for »5 safe deposit boxes, valuables containers, and doors of bank vaults and the like determined.

The invention is explained in the drawing in two exemplary embodiments:

Figure I shows a cross-section through the first version with the main bolt lock open, Figure II the same cross-section, but the main lock 5 is removed from the area of the bolt lock 1, and Fig. III a front view of Fig. I.

ι is the lock plate to which the changeover lock 2 is attached. The blind bolt 3 of this lock is connected to the main lock 5 via a connecting strap 4. Its shift in lock 2 has the task of moving main lock 5. In the opening position shown in Fig. 1 the key to the main lock 5 is inserted through the lock 2. The cylinder of the main lock 5 carries an eccentrically arranged pin 6 through which the lock 7 is adjusted with the locking cleat 8. The main shaft 9 of the Zentralriegelwarkes has a recess 10 into which the stud 8 engages. The lock 7 is automatically engaged in the locked position, so that only to open the lock S is to be blocked.

The handling of the lock is as follows: When unlocking, the blind bolt 3 is first displaced with the key belonging to the changeover lock 2 and the lock 5 seated on the latter is brought under the keyhole of the lock 2. Then the key to the lock 5 is inserted and the bolt 7 is opened with the same by a rotary movement. The entire lock can then be opened by means of the central locking mechanism which operates the main bolt 9.

When the lock is open, the key

was withdrawn to lock 5, through lock 2 lock S is brought into the closed position, whereupon when the central locking mechanism is closed the lock 7 with the cleat 8 automatically into the recess of the main bolt occurs.

It is of course easily possible instead of a as in the exemplary embodiment common keyhole for both

To have keys to use different keyholes as well. Can also be used as Umstellschloß find a combination lock with bolt movement use.

Another embodiment, in which the blind bolt carrying the main lock is controlled by a combination lock, is shown in Figs. 4 to 6.The same is shown in Fig. 4 in a view from above, in Fig. 5 in front view with the front lock plate α ¹ removed and in Fig. 6 in Rear view shown.

The lock plates α ¹ and ο ² are connected to one another by stud bolts. On the lock plate α ² , a central locking mechanism b with the locking shafts c ¹ , c ² , c ³ and c ^{l is} built. The locking shafts c ¹ and c ^{3 are} locked by the bolts d ¹ and dr. The bolt d ¹ is moved by the combination lock h and bolt d ² by the key lock m . The combination lock h has a bolt h ¹ extending to both sides , which presses on the pin ^{1 of} the lock d ¹ at the point h ^a and thereby releases the lock e ¹ , f ^1. The key lock m has a lock shaft m ¹ , which works in the same way on the pin o ^{2 of} the bolt d ² and releases the lock e ² , f ^2. The bolt shaft of the combination lock also carries a pin h ² , which drives angle lever i mounted in point k. This transfers the movement through the pin I ¹ to the shaft /, which in turn is firmly connected to the lock '»». This movement makes it possible to move the key lock into the dot-dash position. In this position, the lock m is brought out of the area of the key entry and the bolt m ¹ .

The handling is as follows:

The positions shown show the opening position of the lock. To close, the shaft W ^{1 of} the lock m is first reset by means of a key, as a result of which the bolt d ^{2 is} released. The same is brought into the closed position by spring pressure in that the bolt e ² engages in the recess f *. The bolt of the combination lock is then reset, the pin σ ^{1 being} released and the bolt d ¹ , as described above for d ² , entering the closed position by spring action. At the same time, by transferring the movement of the bolt shaft h ¹ via the angle i to the shaft / key lock m, it is placed in the dot-dash position.

The lock is opened in the reverse order: after the combination lock has been set, the bolt shaft of the combination lock is displaced and the lock / ^{1 is released} , but at the same time the key lock m is in the open position so that the associated key can be pushed through the Can introduce key guide η. The lock d ² can then be released with the key via the shaft m ¹ , whereupon the lock can be opened by means of the central locking mechanism b . »Ο

Claims (1)

Claim: Door security, in particular for safes and vaulted doors, characterized in that that the locking of the main bolt lifting the main lock on the blind bolt (3) one by a special Key to be used or set up as a combination lock conversion lock (2) sits and through the Shifting this blind bolt out of the area of its interaction with the Bolt lock is brought.
