Description

(1) The invention will be described in the following purely by way of example with reference to a possible embodiment and to the only drawing.

(2) FIG. 1 shows a schematic representation of the locking system in accordance with the invention.

(3) FIG. 1 shows a locking system having an electrically actuable mobile lock 10, an activation means 12, and a mobile end device 14. In the embodiment shown in FIG. 1, the mobile lock 10 is configured in the form of a hoop lock, the activation means 12 as a two-dimensional code, and the mobile end device 14 as a smartphone.

(4) The mobile end device 14 comprises an optical unit 16 in the form of a camera by means of which the mobile end device 14 can interact with the activation means 12 in that the two-dimensional code is scanned or photographed. It is understood that an interaction of the mobile end device 14 with the activation means 12 can take place in that the activation means 12 is an alphanumeric code that is input into the mobile end device 14.

(5) The activation means 12 includes a virtual key that is associated with the lock 10. The virtual key is transferred to the mobile end device 14 (arrow A) and is stored there in a memory 18 of the mobile end device 14 on the interaction of the mobile end device 14 with the activation means 12.

(6) The virtual key transferred to the mobile end device 14 serves to establish encrypted data communication between the mobile end device 14 and the lock 10 (arrow B) to couple the mobile end device 14 to the lock 10 and to authorize the mobile end device 14 to actuate, i.e. to open or to lock the lock 10. The data communication between the mobile end device 14 and the lock 10 here takes place by means of a wireless communication data connection. For this purpose, the mobile end device 14 and the lock 10 each have a transmission/reception unit 20a and 20b respectively.

(7) The transmission/reception unit 20a of the mobile end device 14 and the optical unit 16 and the memory 18 of the mobile end device 14 are each connected in a technical data manner to a control unit 22 of the mobile end device 14.

(8) So that encrypted data communication is possible between the mobile end device 14 and the lock 10, the lock 10 comprises a memory 24 in which a copy of the virtual key is stored. The data can hereby be encrypted by the one of the two communication partners, e.g. by the mobile end device 14 or the lock 10, and can be decrypted by the respective other communication partner, e.g. the lock 10 or the mobile end device 14.

(9) An interaction of the mobile end device 14 does not only have the effect that the virtual key is transferred to the mobile end device 14, whereby the mobile end device 14 ultimately receives an authorization to actuate the lock 10, but also that administration rights are granted to the mobile end device 14.

(10) The administration rights enable the user of the mobile end device 14 to transfer the virtual key from the mobile end device 14 (first mobile end device) to at least one further mobile end device (second mobile end device) not shown in FIG. 1. If the virtual key has been transferred from the first mobile end device 14 to the further, second mobile end device, the virtual key transferred to the second end device also makes it possible to establish an encrypted data communication connection between the second mobile end device and the lock 10 to couple the second mobile end device to the lock 10 and to authorize the second mobile end device for the actuation of the lock 10. In general, administration rights could also be transferred from the first mobile end device 14 to the second mobile end device.

(11) So that the lock 10 recognizes whether a mobile end device 14 is actually an authorized mobile end device 14, not only the copy of the virtual key can be stored in the memory 24 of the lock 10, but also an identifier respectively associated with the or each mobile end device. In addition, which mobile end device has which administration rights can also be stored in the memory 24 of the lock 10. It must be noted at this point that the administration rights provide authorization to read the contents of the memory 24 of the lock 10. The read contents of the memory 24 of the lock 10 can then be displayed by means of a display unit 26 of the mobile end device 14. The display unit 26 is likewise connected to the control unit 22 of the mobile end device 14 in a technical data manner.

(12) If the user of the first mobile end device 14 loses it or if it has been illegally removed, there is the option of carrying out a repeat interaction with the activation means using a third mobile end device that is not shown in FIG. 1 and that replaces the first mobile end device 14. The interaction of the third mobile end device with the activation means effects a new granting of administration rights to the third mobile end device, whereby previously granted administration rights and/or authorizations for the actuation of the lock 10 granted to other end devices can be removed gain.

(13) The procedure of the method for coupling a mobile end device 14 to the mobile lock 10 will be described in the following.

(14) The method starts in that an electrically actuable mobile lock 10 is provided together with an activation means 12, with the activation means 12 comprising a virtual key associated with the lock 10. On an interaction of a mobile end device 14 with the activation means 12, a virtual key is transferred to the mobile end device 14. An encrypted data connection is subsequently established between the mobile end device 14 and the lock 10 using the virtual key. In this respect, the virtual key stored by a mobile end device 14 is compared with the copy of the virtual key stored in the memory 24 of the lock 10. If the virtual key of the mobile end device 14 and the copy of the virtual key stored in the memory 24 of the lock 10 coincide, the mobile end device 14 and the lock 10 are coupled and as a result the mobile end device 14 is authorized for the actuation of the lock 10.

(15) So that the lock 10 only recognizes mobile end devices 14 authorized for the actuation thereof, the identifier identifying the mobile end device 14 is recorded in the memory 24 of the lock 10 on a coincidence of the two virtual keys. On a recognition of the mobile end device 14 by means of the identifier associated with the mobile end device 14, the lock 10 can thus respond accordingly to an actuation query of the mobile end device 14 by an opening or locking procedure.
