• the multi-function anti-theft system 1 according to the present invention can be built into any mechanism or anti-theft device according to the prior art such as, for example:
• the means for detecting the forced opening of the opening-preventing system possibly present in the system 1 are made as at least one microswitch adapted to detect the mutual away movement of the half-cases composing the container without the previous regular disconnection of the system 1 itself;
• an adjustable anti-theft device with safety coil in this case, the means for detecting the forced opening of the opening-preventing system possibly present in the system 1 are made as means for detecting the cutting of at least one of the protecting wires of the safety coil; an anti-theft and safety device for bottles;
• the means for detecting the forced opening of the opening- preventing system possibly present in the system 1 can be made as at least one microswitch adapted to detect the mutual away movement of the half-cases composing the pin without the previous regular disconnection of the system 1 itself.
• multi-function anti- theft system 1 can be embedded into an interchangeable closing device as disclosed in WO-A-2008/142713 of the same Applicant.
• FIG. 2, 3 and 4 it is possible to note such device 3 equipped with the fourth anti-theft, subsystem of the system 1 according to the present invention.
• the means for detecting the forced opening of the related anti-theft container 5, also disclosed in WO-A-2008/142713 comprise two microswitches 7 arranged on the opposite sides of the external body 9, each one of which is kept in a pressed position by a respective half-case 6 when the container 5 is closed (as can be noted, in particular, in FIG. 6) . If the device 3 is regularly open (as can be noted, in particular, in FIG.
• the two microswitches 7 are kept, during the sliding of the device 3 necessary for opening the container 5, inside a respective seat 11 obtained on a corresponding half-case 6 allowing their simultaneous expansions, that reveals the correct use of the detaching device. If the container 5 is forcedly open (as can be noted, in particular, in FIG. 7), only one of the two microswitches 7 is subjected to expansion (obviously the one related to the open half- case 6) signalling to the detecting means of the system 1 the forced opening of the container 5, provoking the activation of the means for emitting the sound and/or lighting alarm signal.
• the electronic card 13 that makes the opening-preventing system is housed in a suitable room 14 inside the external body 9 equipped with a door 15 that can be opened, by opening which it is possible to perform the replacement of the supply batteries 17 of such card 13.
• the ferrite core 19 composing the detecting system of a magnetic type is operatively connected to the opening-preventing system so that, if the receiving means of the opening-preventing system receive the signal emitted by the anti-theft detecting barriers in case of illegal passage detected by such barriers through such detecting system of a magnetic type, the emitting means emit an alarm signal.
• the device 3 is equipped with a closing/opening system 20, of the substantially known type in. the art, with operation, for example, with a locking pin 21 with coaxial or blade-type spring 23 for a magnetic active detaching device, cooperating with the recognition system of the active detaching device itself, and in particular with the receiving and recognition means of the code signal emitted by such detaching device: therefore, if one attempts to open the device 3 by using a detaching device different from the one dedicated to the recognition system, the receiving and recognition means control the emitting means of the alarm signal to emit such signal.
• An interchangeable closing device has been previously described, which is equipped with a multifunction anti-theft system 1 aimed, in particular, to be used with an anti-theft container as disclosed in WO 2008/142713.
