Description

Device for securing locks against improper opening.

The invention relates to a device for securing locks against improper opening, especially of locks in safes and in other areas must be kept absolutely securely under lock and key.

In the case of locks that protect the valuable contents of containers from being damaged To protect the joint opening, it is necessary that either the lock mechanism or the key shape or both is so complicated that unauthorized persons opening the lock is made impossible.

There are many types of locks and keys known to pass through Complicated locking mechanisms in the lock itself and due to the fact that they are extremely difficult to reproduce Keys offer great protection from being counteracted improperly will.

However, all previously known locks and keys have the disadvantage that if the key is lost or stolen, the lock is either lost The key that has arrived is opened unauthorizedly, or by a replica Key is opened. In the case of safes, it is usually the case that several locks are installed are, with one person each holding a key, and thus if necessary can open a lock.Here is the greatest possible security against misuse of the Given the key. But even here cases have become known where criminals unite Identified key bearers, threatened this one and forced the other key bearer announce, to then with the two, unauthorized appropriated keys the two Unauthorized opening of locks.

The invention is based on the object, the lock security with simple means to make so that by a greater spread of the closing elements and complication of the blocking part Verbre = chen can be switched off.

This object is achieved in that a key for a lock sel that consists of several parts that are put together before use need to open the locking mechanism.

To add a key made up of several parts = Lich secure, security elements are provided for each key part if part of the key to be assembled is missing, trigger an alarm. Regardless of this, each is missing.

de part of the composite key causes the lock mechanism could not open The advantages that can be achieved with the invention are in particular in the fact that to secure a container that holds a valuable content, not more several locks with different keys are necessary. It is enough Lock, the key required for this is made up of several parts. In the case of safes, crimes can be largely counteracted as a result, since one cannot works with two locks and thus with two keys as before, but with a lock and any number of key parts secures the safe, whereby it is impossible if the key parts are sent to several people for safekeeping gives that a single person can open the lock, since this is all key parts are needed.

An embodiment of the invention is shown in the drawing = and is described in more detail below: It shows: Fig. 1 A key on the long side consists of two parts (1) (2), each with a swallow on the contact side = have b-tail-shaped recess (3), in each of which half of a double dovetail-shaped fitting piece (4 is inserted for reinforcement.

Claims (1)

Patent claims: Device for securing locks against improper opening, especially of locks in safes and in otherwise absolutely safe under lock and key containers to be held are installed, characterized in that a lock of a key (Fig. 1) is opened, which is made up of 2 parts (1) (2 ), whereby on each contact side of the key parts each one dovetail-shaped Groove (3) is provided. Both longitudinal key parts (1) (2) together and by inserting a double dovetail-shaped fitting piece (4) connected, result in a functional key. 20 device for securing locks against improper opening, especially of locks in safes and in otherwise absolutely safe under lock and key Containers to be held are built in, according to claim 1, characterized in that the lock is opened by a key (Fig. 2), the length of which consists of three Parts (1) (2) (3) is put together, consists. It is in each of the long sides Key parts (1) (2) (3) in the angle tip a dovetail Groove (4) introduced, a fitting piece (5) with 3 each offset at an angle of 120 ° dovetail-shaped formations joined together in the 3 grooves of the three Key parts (1) (2) (3) introduced result in a functional key. 3. Device for securing locks against improper opening, especially of locks in safes and in otherwise absolutely safe under lock and key containers to be held are built in, according to claim 1 and 2, characterized in that that a lock is opened by a key (Fig. 3) that runs along the side four parts (1) (2) (3) (4) is put together. In each of the key parts on the long side (1) (2) ( 3) (4) a dovetail-shaped groove (5) is made in the angle tip. A fitting piece (6) with 4 dovetail-shaped formations offset at right angles placed in the 4 grooves of the key parts (1) (2) (3) (4), result in a working key. "~ - 4. Device for securing Locks against improper opening, especially of locks in safes and are installed in containers that are otherwise absolutely safe to be kept under lock and key, according to claim 1, 2 and 3 characterized in that a lock is from a key (Fig. 4 and 6) which consists of two parts (1) (2) along the long side and also has a split key bit (1) (2), wherein on one contact side half a key part (1) and the key bit part (1) a dovetail shape = ge groove (4) is provided, and on the other contact side of half a key part (2) and the key bit part (2) a dovetail-shaped adapter ( 4) protrudes. By pushing the two key parts on the long side (1 ) (2) the result is a functional key. 5. Device for securing locks against improper use Opening, especially of locks in safes and in otherwise absolutely safe under Closure to be held containers are built in, according to claim 1, 2, 3, and 4 thereby gekennzeichs net that a lock is opened by a key (Fig. 5), the from any number of key length parts (2) and 2 key handle segment parts ( 1) which can be of different lengths is composed. A push button connection the at = the key handle segment parts (1) gives the stability. 6. Device for securing locks against improper use Opening, especially of locks in safes and in otherwise absolutely safe under Closure to be held containers are built in, according to claim 1, 2, 3, and 4 thereby marked = indicates that a lock is opened by a key (Fig. 7), which consists of up to 4 key parts (1) (2) (3) (4) on the long sides and have up to 4 key whiskers (1) (2) (3) (4) divided and undivided can. 7. Device for securing locks against improper use Opening, especially of locks in safes and in otherwise absolutely safe under Closure to be held containers are built in, according to claim 1,2,3,4,5, and 6 thereby marked indicates that an alarm can be triggered by a contact in the lock, if a component of the composable key is missing or not the specific one Has length and dimension.
