• the storage container 2 does not comprise a receiving part for receiving key means for operating the locking device 26, 28, 29 of the storage container 2. Rather, the second locking device 26, 28, 29 is operable by operation of the first locking device 16.
• the storage containers 1 and 2 are coupled with each other via a coupling 61 which may comprise counteracting parts on each of the storage containers 1 and 2 which may be coupled with each other.
• a coupling such as shown in an exemplary manner at reference numeral 61 in Figs. 1 and 2, the storage containers 1 and 2 may be connected with each other, and thus connecting the first locking device 16 with the second locking device 26, 28, 29.
• the coupling device for coupling the storage containers to one another such as coupling device 61 shown in Figs. 1 and 2 may comprise at least one device for providing at least one of an electrical wire connection, and electrical wireless connection, a magnetic connection and a mechanical connection between the storage containers 1 and 2.
• the locking device 16 of the storage container 1 comprises an electrical actuator which actuates upon a corresponding operation of the key means the locking device 26, 28, 29 of storage container 2 through an electrical wire connection of coupling 61 between the storage container 1 and storage container 2.
• the first locking device 16 thus functions as a central locking device which is operable to operate the second locking device 26, 28, 29 when operating the key means through the electrical wire connection (or any other connection as mentioned above) between the different storage containers, and is also oper- able to operate any further locking device for locking and unlocking a respective access member when coupled to the storage container 1. Therefore, locking device 16 functions as a kind of "master locking device” operating respective "slave locking devices” in respective storage containers 2 to 5.
• the invention provides a kind of central electronic locking system which only needs to operate a locking device 16 of storage container 1 for locking and unlocking anyone of the storage containers 1 to 5, so that there is no need to separately operate the storage containers 2, 3, 4 and 5 with separate key means. Therefore, the system according to the invention provides improved ergonomic properties.
• a third storage container 3 or 4 may be coupled to either one of the storage containers 1 or 2 for enlarging the system.
• the third storage container may be storage container 3 coupled side by side to the storage con- tainer 2, or may be storage container 4 coupled side by side to the storage container 1 opposite to storage container 2.
• Each of the storage containers 3 and 4 comprises a locking device, such as locking device 26, 28, 29 as shown with respect to storage container 2, which is operable for locking and unlocking a respective access member of the storage container.
• Such locking device also acts as a "slave locking device", that is the locking device is operable by operation of the locking device 16.
• the storage container 1 is arranged between the storage containers 2 and 4 and is arranged in a way that the locking device 16 operates the respective locking devices of storage containers 2 and 4 through respective coupling devices 61 which are arranged at opposing surfaces 17, 18 of the storage container 1.
• the locking device 16 operates the locking device of storage container 3 through a first coupling device 61 arranged between the storage containers 1 and 2 and through a second coupling device 61 arranged between storage containers 2 and 3.
• the storage container 1 functioning as a kind of "central machine unit” may involve the following components:
• the locking device 16 may comprise an electrically operable key switch provided with a corresponding power supply for providing power to the electrical key switch.
• the locking device may comprise at least one bi-stable solenoid functioning as an actuator, such as actuator 26 shown in Fig. 3.
• Such solenoid may operate at least one mechanical lock assembly such as the lock assembly shown in Fig. 3 with respect to components 28 and 29 which are operable by the solenoid for locking and unlocking the respective access member.
• These components may analogously be implemented in any or each of the locking devices provided in storage containers 1 to 5.
• the mechanical lock assembly which is operable by a respective solenoid for locking and unlocking a respective access member may comprise components such as shown in Fig. 4.
• the mechanical lock assembly 80 according to Fig. 4 comprises at least one pin 83, at least one hook 81 operated by the pin and at least one spring 82 coupled with the pin.
• the mechanical lock assembly comprises several components which interact as follows:
• the involved components as shown in Fig.4 are the hook 81, a push-spring 82, the pin 83, this is the 'shaft' of the solenoid, and a pull-spring 84 (not visible) connecting the pin 83 and the hook 81.
• the solenoid needs an electrical pulse only for the move from locked to unlocked position or from unlocked to locked position. If the mechanism is in the locked-position, the solenoid is in the position as mentioned in the first picture of Fig. 4 (situation 91), a static magnet (not shown) keeps the pin and the complete mechanism in this position (no current supply required). So, in this position the static magnet is stronger than the push-spring 82.
• the solenoid is in the position as shown in the second picture of Fig. 4 (situation 92), the push-spring 82 keeps the pin 83 and the complete mechanism in this position (no current supply required). So, in this position the push-spring 82 is stronger than the static magnet. The pull-spring 84 will only be stretched if the mechanism is locked and the door will be closed afterwards. This is shown in the third picture of Fig. 4 (situation 93). The position in situation 94 equals the position in situation 91. In this way, the springs of the mechanical lock assembly make it possible to close the access member even when the hook is already in the locked position.
