DE19937845A1 - Security lock module for preventing access to secure area by incorporation of safety lock with IC for identification of key user - Google Patents

Abstract

The lock module is operated by an inserted key and/or by a safety lock (2) with an integrated IC (3) and a memory device (4) for identification of the person requiring entry, which is activated by an end contact (7) upon insertion of the key. The lock module can be linked to an alarm system which is operated when an unauthorized entry is attempted.

Description

Security locks not only have the function of protecting a specific area from unauthorized use Protect access; rather, the applicant believes that the task should also be missed to provide information about who can illegally access a certain area and here specifically a security area z. B. outside of his legitimate time, for example for industrial espionage but also for rooms in your own house.

This results in an increased security moment for the security lock, which is now in the Is able to prove who, and at what time, is legitimate or illegitimate in certain rooms was, especially if a time access hierarchy was programmed by a timer.

For reasons of cost, it was not possible to use an IC with separate or integrated Memory blocks are dispensed with, but the security lock itself is the responsibility of the owner to change by hand and can e.g. B. reprogrammed with the appropriate security code become, d. H. a certain legitimation for a certain access area can be prohibited. Of course, such programming can also be sent to a Locksmiths are delegated.

In the proposed variant, it should be particularly pointed out that the Task is seen less in it, an approach that anyway only with raw To open violence is not to protect it with the most unusual materials, but to protect it Obtain proof that a particular person is in an access area that is theirs is available at defined times, has been given unauthorized access at other times.

At the same time, the security lock, which requires minimal development costs, are offered to the customer at a highly attractive price.

In a particularly preferred variant, the normal security lock is used preferably on its top and preferably in the outer lock area with preferably one IC with the appropriate access ports, if necessary a separate storage unit to the individual pin contacts and preferably a single button cell.  

The electronics should be minimized and the lock manufactured with little machining.

In order to integrate the key services in the sales, the programming is via a Additional device makes sense, which with a preferred variant also with little Development effort is to be realized and the programming preferably by a Alpha-numeric keyboard is done.

Ultimately, the preferred variant is to refer to a printing device which, via a security code, enables the lock owner to have unauthorized key users printed out, or that only non-legitimate key users are preferably shown on a display. The invention will now be explained in more detail with reference to claims 1-22 and FIGS. 1-6.

Fig. 1 shows a schematic representation of a sectional drawing through a security lock ( 2 ) in detail. The core of the security lock ( 2 ) is a cylinder ( 10 ), from which the designation cylinder lock ( 2 ) results. In the closed state, small coil springs ( 32 ) (sometimes up to 20) press in pins arranged in the axis of the housing and cylinder bores ( 33 ), which are subdivided into bottom ( 22 ) and top ( 9 ) pins according to the key teeth ( 6 ) upwards, the lower pins ( 22 ) being divided and the dividing line ( 25 ) between the upper ( 23 ) and lower part ( 24 ) of ( 22 ) simultaneously with the correct key ( 1 ) with the dividing line ( 26 ) between the cylinder ( 10 ) and housing ( 27 ) (has double meaning here), so that the cylinder ( 10 ) can be rotated. It can be seen in this variant that the respective IC ( 3 ) can be contacted ( 28 , 34 ) by the dividing line ( 25 ) of the lower pins ( 22 ). The upper pins ( 9 ) only serve to bring the lower pins ( 22 ) into the correct position using the key ( 1 ).

Fig. 2 shows a schematic representation of a sectional drawing through a security lock ( 2 ) in detail with an integrated key ( 1 ). In the illustration, the position of the pins ( 9 , 22 ) by the key teeth ( 6 ) is such that the dividing line ( 25 ) of the lower pins ( 22 ) or the respective upper edge ( 29 ) of the upper ( 23 ) lower pins ( 22 ) exactly coincides with the dividing line ( 26 ) between the cylinder ( 10 ) and the housing ( 27 ), so that the key ( 1 ) and thus the locking lug, which triggers the actual locking process, can be turned to open or close. An incorrect key will raise or lower none or only part of the locking pins ( 9 , 22 ). Likewise schematically indicated here are conductor tracks ( 12 ) through which the corresponding IC ( 3 ) is bonded as well as a memory module ( 4 ), which preferably works in the manner of a shift register and is preferably only selected by the IC / ICs ( 3 ) without legitimation Key user stores and sequentially, starting from the first one. With this procedure, it is conceivable to have an IC ( 3 ) assembled that already contains enough memory space integrated. It should be added that the key in the end position preferably closes a contact ( 7 ), which activates the IC ( 3 ), especially if EEPROMs are used.

Fig. 3 shows a possible pin contact ( 34 ) in a schematic representation. When selecting the lower pins ( 22 ), these contact the IC / ICs ( 3 ) when permutation is selected, with each conductor track ( 12 ) preferably being bonded separately to the respective IC ( 3 ). Of course, the sensible arrangement of the preferred button cell (s) ( 17 ) should be considered.

Fig. 4 shows in schematic representation a possible inductive IC contact. The key bit (S ') is preferably equipped with ferromagnetic elements ( 13 ) which, in a preferred orientation, which would be the case with reversible keys ( 35 ), come into contact with the core ( 31 ) of an electromagnet ( 14 ) which passes through the button cell ( 17 ) excited in the manner of a relay makes a circuit or a contact ( 36 ), here closes to the IC ( 3 ). Of course, the arrangement of the upper ( 9 ) and lower pins ( 22 ) would have to be selected optimally. For this reason alone, this variant is given little prospect of implementation.

Fig. 5 shows a schematic representation of a detail in the area of the outer lock cylinder ( 10 ) with circular contact ( 37 ) to the IC ( 3 ). The front of the security lock ( 2 ) shown shows a vertically arranged pin ( 38 ) in its corresponding bore ( 39 ) which closes the contact ( 37 ) when entering a cylinder latch ( 30 ) without this contact being stored via the IC ( 3 ) in the memory ( 4 ) as an illegitimate closing process. Only when a second cylinder latch ( 30 ') is passed over is the locking process possibly registered as not legitimate and the preferred acoustic and / or visual message appears.

Fig. 6 shows a schematic sectional view of a reprogramming device ( 19 ) in use with a security lock ( 2 ). We recognize the key bit ( 5 ") and housing ( 40 ), which is preferably provided with an alphanumeric keyboard ( 20 ).

In Fig. 6 and other variants, it should not be forgotten that these are electronic components, preferably with their own IC ( 31 ,...) And the corresponding electronic components, which, for. B. also enable a telemetric transmission ( 32 ) to a PC that makes a printout on command.
