Abstract

The system includes, inside the tool, an electronic module for locking/unlocking the tool, in order to block or authorize its use and, inside a control station, a control module for the tool'"'"'s locking/unlocking module designed to switch it from the locked state (i1) to the unlocked state (I0). The system applies well to tools for sealing, nailing and other similar applications.

Claims

1. An anti-theft system for a portable tool, comprising:

a tool module disposed inside said portable tool for electronically locking the portable tool in a locked inoperable state and unlocking the portable tool from the locked inoperable state to an unlocked operable state, said tool module comprising a microcontroller for receiving an electronic unlocking key readable by said microcontroller,

a manual controller, wherein said manual controller is directly connected to a microprocessor;

a control station at a point-of-sale for said portable tool, said control station comprising a control module operably communicating with said tool module, wherein said control module automatically transmits said electronic unlocking key to said microcontroller when the sale of the portable tool is valid,

wherein said microcontroller changes the locked inoperable state of a memory to the unlocked operable state,

wherein said microcontroller reads said electronic unlocking key, and wherein said microcontroller sends a state signal to the microprocessor to switch a functional unit from the locked inoperable state to the unlocked operable state, thereby rendering said portable tool operable.

2. The system according to claim 1, wherein said tool module is designed to switch from the locked state (I1) to the unlocked state (I0) under the action of an electronic unlocking key loaded into the tool'"'"'s (1) locking/unlocking module by the control station'"'"'s control module.

3. The system according to claim 2, wherein the unlocking key of the control station is loaded into the tool by a wire connection.

4. The system according to claim 2, wherein the unlocking key of the control station is loaded into the tool by a radio-link connection.

5. The system according to claim 2, wherein said control module of said control station further comprises a computer for loading the unlocking key.

6. A portable tool customised to the system according to claim 1, comprising an electronic locking/unlocking module for blocking or authorising the use of the tool, the module being designed to receive an electronic unlocking key and to switch the tool into the unlocked state (I0).

7. The portable tool according to claim 6, comprising a diagnostic module for after-sales service and a connecting circuit in order to connect the tool (1) to an after-sales station, in which the connecting circuit ensures loading of the electronic unlocking key.

8. The portable tool according to claim 6, in which the locking/unlocking module is connected to a transponder for receiving the electronic unlocking key.
