Locking device for systems access to which is time-restricted
First Claim
1. In a system for the controlled, time-restricted use of objects of use with a locking device and an access control unit, a method comprisingthe access control unit (1) issuing an opening code (4),the locking device (2) receiving the opening code (4) to unlock an object of use controlled thereby,inputting an end code (6) into the locking device for ending use of the object, andthe locking device outputting a confirmation code (8) and changing the opening code (4→
- 4'"'"').

Abstract
The present invention relates to a locking device 2 for objects of use, which are to be used for a particular period of time by a user, whereby the locking device 2 opens after the input of an opening code 4. The locking device is distinguished in that after input of an end code 6 the locking device issues a confirmation code (8) and changes the opening code in a particular manner (4→4'"'"'). Further, the invention relates to a method for the controlled, time-restricted, use of objects of use, which employs the locking device 2. In this method, an opening code 4 is issued by an access control unit 1, the opening code 4 is input into the locking device 2 for opening the same, an end code 6 is input for ending the use and then a confirmation code 8 is issued, the opening code being altered (4→4'"'"') by means of the locking device 2.

22. A locking device for objects of use, which are to be used for a particular period of time by a user, the locking device comprising:
-
means for unlocking the locking device in response to an opening code; and means for altering the opening code and issuing a confirmation code in response to an end code, hereby the confirmation code serves as proof of the ending of the use; wherein the locking device issues a confirmation code and changes the opening code in response to an end code. - View Dependent Claims (23, 24)

25. A system for locking objects of use, which are to be used for a particular period of time by al user, comprising:
-
a central access control unit; and at least one locking device; wherein the locking device provides a cycle of use in which a locking device provides a request code from which the central access control unit issues an opening code that enables the user to open the locking device; and
in which the locking device provides a confirmation code upon receipt of an end code and changes the opening code. - View Dependent Claims (26, 27, 28, 29, 30, 31)
