Description

The invention relates to a method for producing a replacement part of a locking device, in particular a key or a lock cylinder, using an optically identifiable identification code identifying the replacement part and an optically detectable authorization code with which the authorization of the spare part orderer can be established in a production device based on manufacturing data and authentication data stored there and the spare part is manufacturable.

The DE 10 2005 010 197 A1 describes a cabinet door lock in which a lock cylinder inserted in a housing that can be operated by a suitable key. In order to remove the lock cylinder from the housing, a removal key is provided which has an extended cam. With the extended portion of the cam, a locking cam of the lock cylinder can be moved from a locking position in which the lock cylinder is tied in the housing in a release position in which the lock cylinder can be removed from the housing.

Security cards or other information carriers that carry on a broadside a barcode, a magnetic stripe or otherwise coding, are from the DE 91 09 636.7 known.

The DE 10 2004 043 348 A1 describes a security card for a locking system consisting of several locking cylinders and associated keys, which carries information that is only machine-readable and that is printed as a barcode. The security card is attached when ordering spare parts, and together with the security code, a single-use transaction number is used. The transmission of transaction numbers and the identification code or authorization code takes place in the form of binary code data.

The DE 203 13 780 U1 describes a system for returning a lost key, the key carrying a code for identifying the owner.

From the DE 103 21 307 A1 For example, a method for controlling access using a mobile telephone using a voice dialogue system is known.

The KR 1020110122054 A describes a lock system using a mobile terminal and a bar code identification device.

The US 2004/0012211 A1 describes a padlock on whose housing a barcode is printed.

The invention is based on the object of further developing the ordering of a replacement part of a closing device, in particular a key or a lock cylinder in terms of use.

The object is achieved by the invention specified in the claims.

First and foremost, it is proposed that the optically detectable identification code and the optically detectable authorization code be received by an image recording device. From the illustrations of identification code and authorization code electronically transmitted code data are formed. This code data is sent to the manufacturing facility. The production facility is able to reconstruct the exact configuration of the lock cylinder or of the matching key based on production data stored there from the identification code. Everyone Lock cylinder has this an individually assigned identification code that gives both clues to the dimensions of the lock cylinder as well as clues to its closing secret. With the help of the code data obtained from the authorization code, the manufacturing facility can determine the authorization of the spare parts orderer. For this purpose, the code data obtained from the authorization code are compared with the authentication data stored in the production device. The check determines whether the used authorization code authorizes the ordering of a spare part according to the identification code. During the check, it is determined, in particular, whether the authorization code and authentication data stored in the production device are in a predefined relationship to one another. Location identification data and code data may, for example, be two binary keys of a binary key pair or, in the simplest case, be identical.

In a preferred embodiment of the invention, the identification code is printed on the surface of a lock cylinder. The code carrier carrying the identification code is an imprint in this case. The imprint can also be printed on a sticker, the sticker is then glued to the lock cylinder. The lock cylinder has an end face which has an opening in which a cylinder core is rotatably mounted. The cylinder core has a key channel into which the key can be inserted. A broad side wall of the lock cylinder is covered by the wall of a lock cylinder female housing. When installed, only the front side of the lock cylinder is visible. The identification code carrier is applied to a not visible in the installed state surface portion of the lock cylinder. The designed as a barcode or QR code (Quick Response Code) two-dimensional image code carrier can be detected by an especially designed as a camera image pickup device. The authorization code is preferably on a credit card sized security card printed. This code can also be carried by a two-dimensional image code carrier, for example in the form of a QR code or a bar code. To order, for example, a spare key, a mobile telephone with a camera and a data processing device, namely a so-called smart phone, is preferably used. Images of the identification code printed on the lock cylinder and the authorization code printed on the security card are produced with such a mobile terminal. About a mobile radio link obtained from the image files binary code data are transmitted to the manufacturing facility. In a variant of the invention, it is provided that the authorization code only has to be recorded once and that code data obtained from the authorization code are stored in binary form in the mobile terminal. By means of a computer program running in a processor unit of the mobile terminal, a so-called app, digital images of the code carrier carrying the identification code or of the code carrier carrying the authorization code can be made. The identification code or the authorization code are obtained from the illustrated two-dimensional area code carriers. From this binary code data are formed, which are transmitted via the mobile communication link to the manufacturing facility. The transmitted code data and in particular the code data of the authorization code can be stored by the computer program on the mobile terminal.

The invention further relates to a computer program which is locally stored on a mobile terminal or for use on a mobile terminal on a remote data storage (cloud).

The in the FIGS. 1 and 2 illustrated lock cylinder 2 is used in particular on cabinet doors 8. A door leaf 8 has an opening in which a sleeve-like housing 7 is inserted. In the sleeve-like housing 7 of the lock cylinder 2 is inserted. The design and operation of the lock cylinder are in the DE 10 2005 010 197 A1 described. The entire revelation content of DE 10 2005 010 197 A1 is included in the disclosure of this patent application.

The lock cylinder 2 has a housing with an end face 4 and a broad side surface 3. The broad side surface 3 is in the installed state on the inner wall of the housing 7 and is therefore not visible from the outside. The end face 4 of the lock cylinder, which fills the opening of the housing 7, is visible and has an opening in which a cylinder core 5 is inserted. The cylinder core 5 has a keyway 6 for inserting a matching key 1 or a not shown, but in the DE 10 2005 010 197 A1 in Fig. 13 shown removal key.

With the key 1, the cylinder core 5 of the lock cylinder 2 can be rotated. In this case, a coupling section 9 is entrained. At the coupling portion 9, a closing unit of a cabinet door lock is coupled. However, the coupling section 9 can also carry a closing cam, for example in the form of a preselector.

It is a locking cam 10 is provided which engages in the installed state of the lock cylinder 2 in the housing 7 in a locking recess 11. As a result, removal of the lock cylinder 2 is prevented from the housing 7.

If the removal key, which has an extended key shank, inserted into the keyway 6, it can be brought out of the locking recess 11 by turning the removal key of the locking cam 10, so that the lock cylinder 2 can be pulled out of the housing 7. On the broad side surface of the lock cylinder 2, a code carrier 15 is printed. The code carrier carries a two-dimensional code, namely a QR code. The code carried by the code 15 code is an identification code, which is assigned to the lock cylinder 2 individually, which means that two different lock cylinders 2 are assigned to each other distinguishable identification codes 15, which are optically detectable by means of the code carrier.

The Fig. 3 shows a security card 3. The security card is the size of a bank card. On its broadside surface, a code carrier is printed, which carries an optically detectable code, in particular a QR code. The QR code includes an authorization code 16. In addition, on the security card 12 also a number or number sequence may be printed, which corresponds to the code content of the optically detectable code 16.

If, for example, a key 1 has been lost or if another lock cylinder 2 is to be ordered, the lock cylinder 2 is removed from the housing 7 with the aid of the removal key.

With the camera 17 of a mobile terminal 13, for example, a smart phone, the printed on the broad side surface 3 of the lock cylinder 2 QR code carrying the authorization code 15, and the printed on the broad side of the security card 12 QR code, the carries the identification code 16, recorded. The identification code 15, which is assigned individually to the lock cylinder 2, allows a unique identification of the lock cylinder, so its dimensions and its closing secret. About the identification code 15 can thus determine the structural properties of the lock cylinder 2, so in particular its dimensions and its foundation. With the authorization code 16 printed on the security card 12, an authentication check of the ordering party can be carried out. From authorization code 16 and identification code 15, the authorization of the spare parts orderer can thus be determined as to whether he may order the replacement part to supplement his locking system.

With reference to the Fig. 4 the process according to the invention will be explained in detail.

The manufacturer of a locking system, which has a production facility 14, has delivered to a locking system operator a locking system which has at least one lock cylinder 3 and a matching key 1. The lock cylinder 3 carries an optically detectable identification code 15 in the form of a QR code as an imprint on its broadside surface 3. Each lock cylinder has an individual identification code 15. In the manufacturing device 14 for each identification code 15 individual manufacturing data are stored, the size of the lock cylinder. 2 and the coding for the appropriate key 1 include. These data are associated with an identification code 15 that can be distinguished from other identification codes 15.

The operator of the locking system is given a security card 12 in the establishment of the locking system, which also carries an authorization code 16 in the form of a QR code. In the production facility 14, each associated identification code of the one or more lock cylinders of the locking system is stored for the authorization code 16.

If the locking system operator wishes to have a spare part, for example a spare key 1, which matches the lock cylinder 2, then he removes it with the aid of the DE 10 2005 010 197 A1 described removal key the lock cylinder 2 from the housing 7 and photographed with the camera 17 of a mobile phone 13, the carrier of the identification code 15 and the carrier of the authorization code 16. He thus generates a digital image of the two QR codes.

Previously, a special computer program was loaded on the mobile phone 13, which is able to form from the image of the identification code 15 and the image of the authorization code 16 electronically transferable code data 18, 19 containing the identification code 15 and the authorization code 16. The computer program may further be able to store the code data 19 corresponding to the authorization code 16 on the mobile telephone 13, so that only the identification code 15 has to be included in a future order using the computer program.

About a mobile transmission link 20, which is constructed between the mobile phone 13 and the manufacturing device 14, the manufacturing facility 14, the electronic code data 18,19, ie binary data of the identification code 15 and the authorization code 16 transmitted.

Prior to this data transmission or along with this data transmission, the locking system operator also has to register via the mobile telephone 13 at the production device 14, in which case address data and other shipping data are transmitted.

Based on the data stored in the manufacturing device 14, the electronically transmitted code data 18, 19 checked for authorization to order the replacement part. If the authorization is established, the spare part, that is, for example, a key 1 for the lock cylinder 2, is manufactured in the production facility 14 on the basis of the production data stored there. The identification codes of all locking cylinders produced there or codes correlating to the identification codes are stored in a database of the production device, so that the data record containing the design data according to which the replacement part can be manufactured can be found via the input of the identification code. In the simplest case, the associated data record can be found directly on the basis of the identification code 15. However, it is also possible for a relation to be carried out beforehand, for example a decryption or a signature check of the transmitted identification code 15.

The spare part is then sent to the address transmitted to the manufacturing device 14 during registration.

In the method according to the invention, optically detectable encodings 15, 16 are also generated by means of an image recording device 17 electronically transmitted code data 18,19, which are transmitted in particular wirelessly together with registration data of the manufacturing device 14. It will be beneficial considered that the identification of the lock cylinder or the matching key identification code 15 is not detectable in the normal operating state of the lock cylinder and in particular not visible.

The authorization code 16 may be printed on the lock cylinder. The lock cylinder can also be provided with a code-bearing sticker. Instead of the above-mentioned mobile radio link, another wireless connection can be used for code transmission. It is also possible to use a wired connection. For example, a PC connection over the Internet can be used to transmit the code data. The security card 12 carries the authorization code 16 not only as a barcode or QR code. It can also carry the code as a number combination.
