Description

The invention relates to an electronic anti-theft device for a self-service item, requiring a power supply and comprising a battery.

A self-service item anti-theft device is intended to combat shoplifting by protecting items in a commercial retail establishment by remotely triggering an alarm. The electronic anti-theft device is designed so that an alarm is triggered when the anti-theft device assembled to the article to be protected is near or passes a security gate. Some anti-theft devices use magnetic detection technology and comprise, for example, as a remote alarm triggering system, a piece of ferrite without any electronic module. However, increasingly, in-store anti-theft devices contain additional alarms and use electronic modules that must be electrically powered. These electronic anti-theft devices include batteries for power supply.

Such electronic anti-theft devices consume little power and the batteries last an average of four to five years. When an electronic anti-theft device no longer works because the battery is discharged, the anti-theft device is discarded and replaced. In addition, the anti-theft device is not recycled today because the device is small in size and all the components, including the battery, are molded into a one-piece plastic case. The case is one-piece and non-removable so that its interior is not accessible; in fact the aim being to protect an article from theft and that the alarms can be triggered, a malicious person must not be able to dismantle the case and remove or damage components, which would then prevent any alarm operation.

However, in the context of sustainable development, it is increasingly desired to offer products that can be extended in their lifespan, and easily recyclable.

The object of the invention is to provide an electronic anti-theft device whose life can be extended when the battery no longer works by replacing the battery, and which can be easily recycled. “Battery” means any power source with battery function.

The invention therefore relates to an electronic anti-theft device for self-service sale items in a store, according to claim 1. In particular, the electronic anti-theft device comprises a box which, inside it, houses operating electronics and comprises at least one location for receiving a battery, a fastening element to be assembled with an article to be protected, and means for locking and unlocking the fastening element which are capable of configuring the device respectively, either in a closed position (the closed position being that intended to keep the anti-theft device assembled to the article and locked), or in an open position (the anti-theft device having been unlocked to be uncoupled from the article). The case (the body of the case) comprises an openable part with the function of access to the location intended to accommodate the battery, the openable part being able to be opened only in the non-use position of said electronic anti-theft device.

In the rest of the description, the term “position of use” means the position for which the electronic anti-theft device of the invention is assembled to the article to be protected, and the term “out-of-use position” when the electronic anti-theft device is not mated (or assembled) and locked to the item to be protected. The method of assembly and positioning on the article depends on the type of article to be protected.

Thus, via the openable part according to the invention of the casing which gives access to the battery, the battery can be replaced when it is discharged while perpetuating the electronic anti-theft device, which contributes to sustainable development. Moreover, if the electronic anti-theft device must nevertheless after a certain time be discarded, the battery is recoverable and the anti-theft device is easily recyclable.

In addition, the openable part being able to be opened only in the non-use position of said electronic anti-theft device, it is then impossible to open the case in the use position of the anti-theft device. Therefore, this ensures that the stack does not can be removed in the use position, the electronic anti-theft device therefore remaining in operation and capable of triggering one or more alarms.

According to one characteristic, the openable part forms a portion of the body of the casing and is able to close an opening made in said body of the casing and opening inside the casing on the location intended to accommodate the battery.

According to another feature, the openable part is capable of being movable and/or removable relative to the body of the case. In embodiments of the anti-theft device (in particular for an anti-theft device for clothing or an anti-theft device for hanging from an article (with hoop as attachment element)), the openable part is in particular able to be mobile and/or removable. only in the open position of said electronic anti-theft device.

Advantageously, the location comprises a housing adjusted to the volume of at least one battery.

In one embodiment, the slot is arranged in the openable part, preferably the slot further comprising a reception housing adjusted to the volume of at least one battery. Thus, the location not being integral with the interior of the case but being in the openable part, when said openable part is opened by being removed from the body of the case (not its removable aspect) or offset with respect to the body of the casing (due to its mobile aspect), access to the location is particularly easy and it is even easier to change the battery. Preferably, the openable part includes the location of the battery, and is movable relative to the rest of the case. The openable part comprising the location of the battery is movable so as to be offset relative to the rest of the case. The openable part comprising the location of the battery can therefore adopt a closed position by being integral with the rest of the case (said at least one battery is inaccessible), and an open position to be offset with respect to the rest of the case (and access thus to said at least one stack). Advantageously, the openable part comprising the location of the battery is movable by pivoting, or else is movable by being removable relative to the rest of the case. In the latter case, the openable part comprising the location of the battery is movable while being removable with respect to the rest of the case in the manner of a drawer. The openable part comprising the location of the battery further comprises a housing participating in the locking of the anti-theft device in its closed position, in particular comprises a housing which is intended to receive part of the fastening element in the closed and locked position of the anti-theft device (preventing any opening of the openable part). Advantageously, the openable part only houses said at least one battery and said housing participating in the locking of the anti-theft device in its closed position. Advantageously, in the open position of the openable part, the rest or the interior of the casing is closed. Thus, the interior of the case is inaccessible, in particular it is not possible to access the operating electronics and other operating parts of the anti-theft device.

According to one embodiment of the electronic anti-theft device, the openable part is arranged (in the body of the housing) so as to be inaccessible in the position of use of the anti-theft device. In particular, the openable part is located in a zone of the casing which is intended, in the position of use of the electronic anti-theft device, to be affixed against the article to be protected.

When the electronic anti-theft device is an anti-theft device for a bottle, the openable part is located in a zone of the casing intended to be applied against the bottle.

When the electronic anti-theft device is an anti-theft device for clothing comprising two parts that are movable or removable relative to each other and which have two opposite faces intended to sandwich a garment, one of the parts constituting the housing, the openable is arranged in an area of the housing which forms one of said two opposite faces.

The openable part which is able to close the access opening to the location of the battery, is preferably integrated into the surface of the body of the casing without protruding with respect to the rest of the body of the casing in the closed position of said open part. The opening part can be closed without being locked. As a variant, it can also be locked. The qualifier “locked” relative to the openable part is understood to mean the fact that the openable part is blocked in its closed position.

In an exemplary embodiment, the openable part is a cover of flat shape (and optionally of curved shape).

In one embodiment, the openable part is visible, closed and locked in the position of use of the electronic anti-theft device. In particular, the openable part is locked by the attachment element when the electronic anti-theft device is in the closed position (that is to say when the attachment element is in its closed and locked position).

In this last embodiment and according to an exemplary embodiment, the attachment element forms a hoop with a branch whose distal end is imprisoned in the casing and whose other branch, called the closing branch, comprises its distal end which is capable of being extended, or retracted and locked in the casing by the locking and unlocking means, the openable part comprising a housing which is intended to receive the termination of the distal end of the closure branch in the retracted and locked position of said distal end so as to prevent the opening of the openable part, in particular the electronic anti-theft device being used while being suspended by the hoop from an article to be protected. The hoop can be rigid or flexible, and is made of a material which is difficult to cut.

In this latter embodiment, the openable part is preferably movable by pivoting, preferably the openable part also cooperates with the case by clipping (for its closure). The openable part can form part of the peripheral edge (dimension of the thickness) of the body of the casing.

Preferably, the openable part cooperates with the casing (the body of the casing) by clipping.

In a preferred embodiment, the electronic anti-theft device comprises a remote triggering alarm system, in particular operating by radio frequency (RF) technology or acousto-magnetic (AM) technology, and an integrated alarm, and preferably a diode, the integrated alarm being adapted to be activated, triggered and deactivated by the battery-powered operating electronics, the deactivation of the alarm by the operating electronics being generated when the electronic anti-theft device is positioned against a deactivator of electronic labels. Such an electronic anti-theft device is more particularly described in the patent application FR2102079 of the applicant. This anti-theft device which requires a power supply by battery has all the characteristics of the device of the invention to have easy access to the battery while guaranteeing its inaccessibility in the position of use of the device.

The electronic anti-theft device 1 of the invention illustrated in the figures is intended to be assembled with a self-service store item to protect it against theft, by being capable of triggering one or more alarms in the event of an attempted theft of the article on which the anti-theft device is assembled and/or in the event of malicious (and therefore unauthorized) opening of the anti-theft device.

The electronic anti-theft device 1 of the invention comprises a box 10 housing the operating electronics of said anti-theft device, an attachment element 2 for assembling the anti-theft device to the article to be protected, the anti-theft device 1 being capable of adopting either an open position to be able to assemble the attachment element 2 to the article, or a closed position when it is assembled to the article, and a locking and unlocking system 3 to lock the attachment element 2 in the closed position of the anti-theft device 1 and to unlock it in order to open the anti-theft device 1.

The operating electronics of the anti-theft device 1 need to be electrically powered by a battery 4 which is intended to be housed inside the casing 10.

The electronic anti-theft device 1 of the invention is designed to be able to change the battery 4.

The body of the box 10 comprises an openable part 11 for access to the location of the battery 4. The openable part 11 is able to be opened only when the anti-theft device 1 is not in the position of use, c ie is not in the assembled position on the article to be protected. Thus, when the anti-theft device 1 is assembled to the article to be protected, the openable part 11 cannot be opened, which prevents any possibility of removing the battery, guaranteeing the operation of the anti-theft device (that is to say its ability to trigger alarm(s).

The openable part 11 is able to be removable and/or mobile. The openable part 11 forms a portion of the body of the casing 10 and is capable of closing an opening or window 12 in the surface of the body of the casing 10. The opening or the window 12 provides access to the location of the battery 4 The openable part 11 is therefore integrated into the body of the casing 10, it is integrated into the thickness of the casing body. Advantageously, the part opening 11 does not protrude from the body of the case, it blends into the wall of the case 10.

The housing 10 comprises in its interior a location 13 for the battery 4 which preferably takes the form of a housing 13 which is adapted to receive the battery 4, that is to say that said housing has a volume adjusted to the insertion volume of the battery. Depending on the type of electronic anti-theft device 1, that is to say according to its use (for bottle, or clothing, or article from which the anti-theft device is suspended, or other), the location or the suitable housing 13 of the battery is arranged either in the openable part 11 or in another part of the housing.

According to a first embodiment of the electronic anti-theft device 1 (described opposite the figures 1 to 5 relating to two examples of use), the openable part 11 is arranged in the body of the housing 10 so as to be inaccessible in the position of use of the anti-theft device. The openable part 11 is arranged in a surface 14 of the body of the case which is inaccessible in the position of use of the electronic anti-theft device 1. This surface 14 is made inaccessible because this surface is applied against the article to be protected in position use of the electronic anti-theft device, or (for the example of figure 4 and 5 ) due to the simple closed position of the electronic anti-theft device. In this first embodiment, the openable part 11 is closed without however being locked. Alternatively, it could also be locked.

According to a second embodiment ( figures 6 to 8 ), the opening part 11 is closed and locked in the use position of the electronic anti-theft device 1. Although the opening part 11 may be visible and accessible in the use position, it cannot be opened because it is locked in the closed position.

In the first embodiment such as in the example illustrated in the figures 1 to 3 relating to a 1A electronic anti-theft device for bottles or in the example illustrated in the figure 4 and 5 relating to an electronic anti-theft device 1B for clothing, the openable part 11 is a cover which forms a portion of the surface 14 of the body of the case 10 and which is able to close a window 12 in said surface of the body of the case 10. The cover 11 is inaccessible in the position of use of the electronic anti-theft device 1: for the electronic anti-theft device 1A for bottles, the surface 14 equipped with the cover 11 is intended to be affixed against the bottle, and for the electronic anti-theft device 1B for clothing, the cover 11 closing the access opening to the battery is arranged inside the electronic anti-theft device 1 which closes like a clamp and sandwiches the garment inside the clamp between the two faces opposite to each other 14 and 14'. In these two examples, the cover 11 is here removable. The cover 11 is fixed by clipping.

In view of figures 1 to 3 , the electronic anti-theft device 1A is an anti-theft device for bottles. It comprises the housing 10, the attachment element 2 in the form of an attachment ring intended to be tightened around the neck of a bottle, and preferably a cap 20 intended to secure the cap of the bottle in particular to prevent any loosening of the cap when the latter is screwed. Cap 20 is integral with casing 10. Cap 20 extends laterally relative to casing 10. Cap 20 is preferably transparent. The attachment ring 2 also extends laterally to the housing 10. The cap 20 is disposed above the attachment ring 2, and preferably bears directly against the surface of the entire periphery of the attachment ring 2 in the position of use to avoid any insertion of a tool between the attachment ring and the cap. The attachment ring 2 is capable of adopting two positions, an open position (also called unlocked), and a closed position (called locked) around the neck of the bottle. The attachment ring 2 has an open interior space which is intended, in the closed position of the ring, to be circular to match the circular cylindrical neck of the bottle. An anti-theft device of this type is for example described in the patent EP2634696B1 and in the patent application FR1913440 of the applicant. The locking and unlocking means 3 are housed in a rigid envelope 3A, preferably in the same plastic material as that of the attachment ring 2. The rigid envelope 3A is arranged on the body of the attachment ring 2 and opposite the housing 10. Such locking and unlocking means 3 associated with the attachment ring 2 are for example described in the aforementioned patent EP2634696B1 . Other variants of the locking and unlocking means 3, in particular as regards their arrangement, are possible. The locking and unlocking means 3 are suitable for retaining the attachment ring 2 by inserting a free end of the ring therein. The envelope 3A housing the means of locking and unlocking 3 constitutes a portion of the anti-theft device projecting outwards relative to the body of the attachment ring 2, so as to be able to cooperate with a detacher to ensure the unlocking (and therefore the withdrawal of the anti-theft device 1 of the item).

The body of the housing 10 of the anti-theft device 1A for a bottle is generally parallelepipedic in shape and comprises the so-called internal face 14 which is intended to bear against the neck of the bottle in the position of use of the anti-theft device 1A. The inner face 14 opens onto the interior volume of the anti-theft device delimited by the interior of the attachment ring 2 and the interior of the cap 20 when it is present. The internal face 14 comprises the window 12 which gives access to the housing 13 of the battery 4 which is thus removable. The window 13 is adapted to be closed by the openable part 11 here in the form of a cover of flat shape and of slightly curved shape. Here the fixing is done by clipping. The cover 11 comprises "unclipping" means 11A such as at least one groove, which allow a thin tool to be inserted in order to lever to disassemble said cover. The accessibility of the openable part (cover) 11 is obtained in the non-use position of the anti-theft device for bottles, whether the device is in its open or closed position.

In the illustrated embodiment of the electronic anti-theft device 1A for a bottle, the battery 4 provides the power supply to a diode 5 visible on the top of the box 10 and to an electronic unit internal to the box which controls the activation and the deactivation of a specific integrated alarm such as that described in the patent application FR2102079 of the applicant. The specific built-in alarm provides an additional alarm to the electronic anti-theft device (alarm separate from a usual remote alarm triggering system such as a ferrite that does not need a battery), said specific built-in alarm cannot be deactivated than passing the electronic anti-theft device in front of a tag deactivator. As the electronic deactivators are located exclusively at store checkouts (or at least in localized and monitored places), a malicious person without going to the checkout, who would open the anti-theft device within the store, whether by a detacher-type magnet, or by forcing it open, would automatically trigger the electronic anti-theft device's built-in alarm (since it has not been previously deactivated with an electronic tag deactivator). The electronic unit of this anti-theft device is capable of detecting the closing of the electronic anti-theft device in order to activate the specific integrated alarm. Closing is detected via a mechanical position sensor which is visible under reference 6 on the figures 1 and 2 , and is arranged on the inner face 14 of the electronic anti-theft device to detect the positioning, the assembly of said anti-theft device 1 against the bottle in the use position. The operation of this anti-theft device requires a battery.

In the embodiment of the figure 4 and 5 , the electronic anti-theft device 1B for clothing comprises two parts or arms 21 and 22. The first arm 21 forms the fastening element 2 by comprising a pinning element 21'. The second arm 22 forms the housing 10 and comprises in its internal face 14 (face facing the first arm 21) a housing 23 to accommodate the plug-in element 21' of the first arm 21. The plug-in element 21' is intended to be hooked onto a garment for assembling the anti-theft device 1. Preferably, the two arms 21 and 22 are integral with each other and articulated with respect to each other to use the device electronic anti-theft device 1B in the manner of a clamp, which provides rapid positioning of the electronic anti-theft device on the article and avoids losing the plug-in element 21' during removal. A spring 24 is preferably provided at the hinge, which provides extremely rapid opening of the electronic anti-theft device. The operating principle of such an anti-theft device is described in particular in the patent EP2419587B1 of the applicant. The locking and unlocking means 3 are housed inside the casing 10 (second arm 22) provided with the housing 23 intended to accommodate the plug-in element 21'. The locking and unlocking means 3 are suitable for retaining the plug-in element 21' in the housing 23. The housing 10 of the anti-theft device 1 has a portion 3B projecting outwards from the outer face 15 opposite the first arm 21, this projecting portion 3B housing the locking and unlocking means 3 so as to be able to cooperate with a detacher to ensure the unlocking (and therefore the removal of the anti-theft device 1 from the article). In the example shown, the electronic anti-theft device 1B comprises a diode 5 housed in the casing 10 (the second arm 22 of the clamp) being visible on the external face 15. Diode 5 is powered via a battery which is removable relative to the interior of case 10. Access to the location of the battery is via a window 12 formed in the internal face 14 of case 10, window 12 which is closed by the openable part 11 in the form of a cover. The openable part 11 is here fixed by clipping and comprises “unclipping” means such as at least one groove 11A. Just as described above for the electronic anti-theft device 1A for bottles, this electronic anti-theft device 1B for clothing comprises a specific integrated alarm described in the patent application FR2102079 , and a specific built-in electronic alarm control unit that require battery power. The electronic anti-theft device 1B also comprises a mechanical position sensor 6 which detects when the first arm 21 is closed against the second arm 22, signifying that the electronic anti-theft device 1B is closed, which activates the specific integrated alarm.

The electronic anti-theft device 1B for clothing here has an elongated shape but could have another shape such as a macaroon shape with two moving or removable parts relative to each other.

In the second embodiment of the electronic anti-theft device illustrated in the figures 6 and 7 which relate to an electronic anti-theft device 1C adapted to be suspended from an article to be protected, and for which the openable part 11 is visible in the position of use, the openable part 11 being closed while being locked. The openable part 11 is locked by means of the attachment element 2 when the latter is in its closed and locked position. The openable part 11 forms part of one side and the thickness of the body of the case 10. The openable part 11 is preferably assembled (closed) by clipping. The openable part 11 is here movable in pivoting at the level of a hinge 16 located in a corner of the case opposite the attachment element 2. Alternatively, the openable part 11 could for example be removable and be movable by translation like a drawer.

The electronic anti-theft device 1C is an anti-theft device mainly used for articles having a part forming a ring (such as an irremovable strap of a leather goods article) or having an orifice (such as an eyelet of a lace-up shoe ). The electronic anti-theft device 1C is intended to be suspended from the article to be protected. The electronic anti-theft device 1C comprises the element attachment 2 in the form of a hoop, here rigid, which is intended to be passed around the strap of the article or through the orifice of the article. The hoop 2 has an inverted U-shape with two branches, a branch 25 called the fixing branch and a branch 26 called the closing branch. The attachment branch 25 of the hoop 2 is fixed (irremovably) in the body of the case 10 while being capable of being movable by translation and pivoting, while the other closing branch 26 is able to come out of the case. and to enter it thanks to the mobility of the fixing branch 25. Such an anti-theft device is for example described in the patent EP2491212B1 of the applicant. The locking and unlocking means 3 are housed inside the casing 10. The locking and unlocking system 3 is capable of retaining the closure branch 26 once introduced into the casing. This is, for example, a magnetized system that moves via a spring. The electronic box 10 has a portion 3C projecting outwards relative to the rest of the body of the box and in which the locking and unlocking means 3 are housed so as to be able to cooperate with a detacher to ensure the unlocking (and therefore removing the anti-theft device from the item).

In this electronic anti-theft device 1C to be suspended, the opening part 11 is adjacent to the projecting portion 3C housing the locking and unlocking means 3. The opening part 11 is able to close an opening 12 which is located on the edge of the case 10. The openable part 11 is in the closed position in alignment with the closure branch 26 when the latter is in the retracted position in the case 10.

To ensure locking in the closed position of the openable part 11, said openable part 11 comprises (inaccessibly from the outside) a housing 17, preferably funnel-shaped, capable of receiving the distal end 27 of the branch closure 26. The locking and unlocking means 3 are capable of locking the closure branch 26 in its retracted position by cooperating with the portion of the closure branch located just above (upstream) of the distal end 27 Thus, since the distal end 27 of the closure branch 26 of the attachment element 2 is arranged in the housing 17 of the openable part 11 and that the closure branch 26 is locked, the openable part 11 is she too locked. The opening part 11 cannot therefore be opened because it is retained inside the casing 10 by the closing branch 26 of the fastening element 2.

The openable part 11 is for example assembled by clipping. The casing 10 comprises "unclipping" means 11A such as at least one notch arranged on an edge of the body of the casing and cooperating by mutual engagement with a shape 11B for clipping the openable part 11. The notch 11A is designed to allow the insertion of a very thin tool and leverage to ensure opening. The opening of the openable part 11 can only be done when the closing branch 26 is unlocked and is outside the case 10.

The openable part 11 includes the location of the removable battery 4, in particular the adapted housing 13. By opening the openable part 11, the battery 4 is directly accessible.

In the example represented, the electronic anti-theft device 1C comprises a diode 5 housed in the casing 10 while being visible on the external face of the casing. The diode 5 is powered via the battery 4. As described above for the electronic anti-theft device 1A for bottles or 1B for clothing, this electronic anti-theft device 1C to be suspended comprises a specific integrated alarm 7 described in the patent application FR2102079 , and a specific integrated electronic alarm control unit requiring battery power supply. The electronic anti-theft device 1C also comprises a mechanical position sensor 6 (which is internal to the casing 10 and is not visible externally) which detects when the closing branch 26 is locked, signifying that the electronic anti-theft device 1C is closed, this which activates the specific built-in alarm 7.
