Definitions

• the present invention refers to the field of anti-theft housings consisting of two hinged hulls lockable by a deactivatable mechanism only with the aid of a specific unlocker.
• These housings incorporate in known manner an electromagnetically interacting means (by radio frequency or magnetoacoustic coupling, or by an RFID tag) with a gantry disposed at the exit of a self-service space.
• an electromagnetically interacting means by radio frequency or magnetoacoustic coupling, or by an RFID tag
• the case triggers an alarm when passing not in front of the payment box, but in front of a passage equipped with a gantry detection.
• one solution is to force the enclosure to retrieve the article.
• the storage container is in the form of a box having a base and a lid, with the article of merchandise received in the base.
• the lid is locked to the base by a mechanism of locking.
• the storage container also has an internally disposed alarm system that is activated when the lid is locked to the pedestal and is disabled when the lid is unlocked from the pedestal.
• the lid can only be unlocked with a key provided for this purpose.
• the alarm system contains a flashing LED that indicates to the consumer that the storage container has an alarm activated.
• the alarm system further includes an EAS tag for operating a security door at an exit to the protected environment; and further includes a sound device that will emit a loud sound if one tries to leverage to disengage the lid of the base when the lid is in the locked position.
• the sound device will also emit noisy sound if the locked storage container is brought near a security door.
• the sound device will emit noisy sound for a predetermined period of time and will continue to emit that sound even if the safety storage container is removed from the protected environment.
• European patent application EP1841935A1 discloses an anti-theft safe for the protection of goods comprising a main body defining an interior space for the goods to be protected, a cover ensuring the closure of said main body, an alarm transmitter triggering a central alert during the passage the anti-theft lock box of an alert gate, and a releasable lock securing the lid to the main body.
• the anti-theft safe according to the invention also includes an internal alarm circuit which is controlled to be initiated when the releasable lock is in a lock position and de-energized when the releasable lock is in an unlocked position.
• the internal alarm circuit comprises a first switch, which in the primed state is arranged to trigger the alarm circuit for the transmission of a sound signal in the case where the first switch indicates the separation of the cover and the main body.
• the first problem is that the activation of the sound device is done simultaneously and inseparable with the locking of the housing.
• the solution of the prior art does not allow to lock the housing at first, and then trigger the audible alarm when the housing is actually put in place on the shelf. This results in problems of autonomy, because the sound alarm consumes even at rest energy, which reduces the autonomy when the case is kept in stock, waiting for storage on the self-service.
• a second problem is that the mechanism for triggering the audible alarm acts only in certain types of forced opening, and does not completely prevent an opening by the rupture of the articulation provided opposite the locking mechanism , with a holding of the locked part in position.
• the object of the present invention is to overcome these disadvantages by proposing an antitheft box comprising a security assembly for independently activating the local alarm function on the one hand and the anti-theft function when passing through the detection gantry on the other hand, with improved sensitivity and reliability during the forced opening of the housing.
• the invention relates in its most general sense to an anti-theft housing consisting of two shells hinged at one end by a hinge and having at the other end a locking means comprising an audible alarm characterized in that it comprises a first movable zipper in translation and activatable by an action on the front wall of the locking mechanism, and acting on the locking means of the two shells when they are assembled, and a second mobile zipper in translation independently of the first one; zipper, activatable by a separate action on the front wall of the locking mechanism, ensuring the activation of the audible alarm.
• This structure makes it possible to separately control the locking and the activation of the alarm.
• the locking mechanism forms a safety device having an upper part of which one of the end faces has two openings for the passage of the end of the two movable drawbars and a lower part of larger section having an opening for the interaction between the locking mechanism and a complementary part provided on one of said shells, said device being configured to be engaged in one of the shells.
• the housing comprises a detector coming into contact with the edge of one of the shells when the housing is in the closed position.
• said detector is a contactor integrated in said safety device in that the shells are supported, in closed position, on the opposite faces of said safety device, offset from said contactor.
• This embodiment causes the release of the contactor even when the forced opening of the housing is from the opposite end of the locking device. Shifting the edges of the shells produces a lever arm that amplifies the movement that then occurs at the line of contact between the edges of the two shells and the side surface of the device enclosing the locking mechanism and alarm.
• the locking mechanism is locked in the locking position by at least one movable member interacting magnetically with a specific unlocker, and in that the mobile tab for activating the alarm is locked in the alarm position by at least a movable member magnetically interacting with said specific unlocker.
• the electronic circuit comprises a coil placed in a central position with a longitudinal orientation.
• the aim is to prevent the application of an external magnetic field from disturbing the operation of the alarm.
• the electronic circuit of the alarm comprises an electromagnetic shielding preventing disturbance by an external magnetic field.
• the locking mechanism comprises at least three independent locking points. These points may be movable flyweights longitudinally and / or transversely, or for some of the points, a flexible blade interacting with a shoulder to block the locking zipper.
• the alarm means further comprise a radiofrequency transmitter.
• This transmitter is activated simultaneously with the audible alarm to emit an information signal enabling a central station to trigger an interception of the carrier attempting to force the housing.

• the invention shown in Figure 1 comprises a housing formed of two shells (1, 2) of transparent plastics, complementary shape to form, in the closed position, a box in which is inserted the article to be protected.
• the two shells are hinged together by a hinge (3).
• the face opposite to the hinge of one of the shells has two faces (4, 5), one of which has a slot (6) for receiving a safety device (6) containing the locking mechanism and the integrated alarm .
• the emergent portion which extends this lower part (8) has a lower section to the lower part (8).
• the emergent portion (9) constitutes the trigger containing the locking mechanism.
• the safety device (7) can be engaged in the window (6) of the shell (2) from the inside when the housing is open. When the housing is closed, the safety device (7) can no longer be removed. This embodiment allows a great modularity of a system comprising housings of different dimensions, but all using the same safety device (7).
• This safety device incorporates two independent mechanisms, one ensuring in known manner the locking of the housing in the closed position, the other ensuring the activation and deactivation of an integrated alarm in the device, and comprising a supply battery (10) and an acoustic transducer (11).
• the device also includes a switch (15) arranged to interact with the edge of the opposite shell when the housing is closed.
• FIGS 3 and 4 show an enlarged view of an alternative embodiment of such a safety device.
• the emergent portion (9) has a transverse front face (12) having two slots for the passage of the ends (13, 14) of two movable pulls actuating one the locking mechanism and the other integrated alarm.
• the device comprises in known manner flyweights
• weights (16, 17, 18) arranged in a coded manner to interact magnetically with magnets provided on the unlocker.
• One or more of the weights lock the locking puller (14) in the locked position, and one or more other weights ensure the locking of the pull tab (13) for activating the alarm when it is in position d 'alarm. It is thus possible to deactivate the alarm only when the ad hoc unlocker is available.
• These weights (16, 17) have a shoulder (26, 27) preventing the disengagement by a simple shock, and imposing that the unlocking can be achieved only by the joint action of the unlocker and a pressure perpendicular to the movement of the weights exerted on the end of the drawbars (13, 14).
• the device has lateral slots (19, 20) for the passage of claws (51) provided on the opposite shell, these claws (51) interacting with the locking mechanism to prevent opening of the casing when the latter is locked ( see Figure 7).
• the drawbars (13, 14) are associated with springs
• the locking puller (13) has a longitudinal indentation (29) for moving the counterweight (50) transversely movable and securing the alarm puller (14), both when the locking pull (14) is in the locking position when it is in the position of release hulls.
• flyweight for locking the drawbars is a known solution, which could be replaced by other locking means such as a flexible blade magnetically interacting with a magnet of an unlocker.
• Figure 6 shows a front view of the safety device.
• the front face (12) has two slots for the passage of a pull tab (13) for activating the alarm and a pull tab (14) for locking.
• the user can independently operate one or the other zipper according to the function he wishes to activate.
• the device also has a longitudinal slot (30) for engaging the edge of the opposite shell. At the bottom of this slot is housed the contactor whose probe (25) is flush with the surface of the bottom of the groove (30).
• Figure 7 shows a cross-sectional view of a housing equipped with such a safety device.
• the safety device is mounted on one of the hulls (1).
• the longitudinal edge (32) of the complementary shell (2) is inserted into the slot (30), whose bottom has a contactor (25).
• This contactor interacts with a central zone of the edge of the complementary shell. Centering makes it possible to obtain the most effective effect for triggering in the event of forced opening, whatever the mode of stress exerted on the two shells.
• the contactor When both shells are assembled, the contactor is activated and commands the alarm to stop. On the other hand, when the edge (32) stops pressing the contactor (25), the contactor is released and triggers the alarm. This situation occurs when one tries to separate the two parts of the hull, especially in case of destruction of the locking mechanism or in case of forcing of the latter.
• Figures 8 to 11 show views of an alternative embodiment of a safety device according to one invention.
• the two drawbars (13, 14) are independent of one another, and are movable parallel. They each have an end protruding from the front wall (12) to allow their displacement in a longitudinal direction, by a transverse pressure.
• the device comprises a ferrite (40) associated with a circuit tuned for detection when passing through a gantry having an induction loop.
• Figure 9 shows the device in the situation where the two drawbars are pushed into the cocking position.
• the locking trigger (14) is held in the locking position by a flyweight
• Figures 10 and 11 show another configuration where only the latch (14) locking is engaged, the pull tab (13) controlling the activation of the alarm circuit being disengaged.
• the device then locks the housing, but does not trigger an alarm.
• the alarm circuit is not electrically powered, and the autonomy of the device is thus preserved.
• the device can also be used simply without alarm when one wants to avoid the annoyance of strident ringing in case of unexpected handling.
