Description

TECHNICAL FIELD OF THE INVENTION

"ANTI-THEFT PROTECTION SYSTEM INCLUDING A LONGILINE HOUSING AND A CLOSURE DEVICE"

[001] The invention relates to an anti-theft protection system of an article to be protected.

[002] The invention relates more particularly to antitheft protection systems of elongated articles, such as mascara tubes, lipstick, nail polish or cosmetic powder, for example.

STATE OF THE ART

[003] The anti-theft cases of an article are well known in the prior art. Generally, these boxes are used to protect items such as CDs, DVDs, CD-ROMs, cosmetic accessories ...

[004] These protection boxes allow to associate securely detection tags to an article to protect. Also, if such a case containing an article to be protected has left a surveillance zone, an alarm is triggered so as to warn the security services of an attempted fraud.

[005] Such housings are described in particular in patent applications FR 2 854 722 or EP 1 049 847 in the name of the applicant.

[006] However, these housings are relatively bulky and are not suitable for the protection of elongated objects, such as lipstick tubes or mascara for example.

[007] Indeed, the housings have relatively massive shapes and the locking means are relatively bulky, so that a reduction in the dimensions of the housing to obtain an elongated housing is not possible. OBJECT OF THE INVENTION

[008] The invention aims to remedy these problems by proposing an anti-theft system for the protection of an elongated item that is compact and has a satisfactory ergonomics.

[009] For this purpose, and according to a first aspect, the invention proposes a system for theft protection of an article comprising:

an elongate housing comprising a first end having an orifice;

a device for closing the orifice, able to engage in the orifice in a longitudinal direction to the housing in order to close said orifice in the protective position, said device comprising magnetic locking means comprising at least one locking member movable between a locking position of the closure device on the housing and an unlocked position and at least a first movable metal element, under the influence of a magnet, in the longitudinal direction of the housing, between at least one locking position of the locking member in its locking position and a release position in which the locking member is unlocked.

Thus, the housing is elongate and these dimensions can be adapted to the protection of an elongated article.

In addition, the manipulations are simple since on the one hand, the closing device engages and disengages from the orifice along the longitudinal axis of the housing and on the other hand, the unlocking is effected by a magnetic attraction in the same longitudinal direction of the housing. The housing can therefore be grasped vertically for the unlocking operations and engagement and disengagement of the closure device in the housing, which is particularly satisfactory from an ergonomic point of view.

Advantageously, the locking means comprise a second metal element movable in a direction perpendicular to the direction I, under the influence of a magnet, between a locking position of the first element. metal in its locking position of the locking member and a release position of the first metal member. Preferably, the locking means also comprise a third metal element movable in a direction perpendicular to the direction I, under the influence of a magnet, between a locking position of the first metal element in its locking position of the organ locking and a release position of the first metal member. Thus, the safety of the device is enhanced because the mechanism can not be unlocked by approaching a single permanent magnet. Indeed, by providing a second and / or a third movable metal element whose direction (s) of magnetization is not parallel to the direction of magnetization of the first metal element, two or three magnets must be judiciously arranged to unlock the closure device.

Advantageously, the closure device comprises an inner skirt having a shape complementary to an inner wall of said first end, so as to fit inside the housing, and an outer skirt having a shape complementary to a wall outer of said first end so as to cover said first end. Thus, the system is particularly resistant to burglary attempts. In addition, advantageously, the inner skirt provides protection for the locking member.

Advantageously, the housing comprises an annular shoulder against which an upper edge of the inner wall abuts, in the protective position. This shoulder prevents the introduction of an object capable of forming a lever, such as a blade, between the outer skirt and the housing.

In one embodiment, the outer skirt is mounted mad relative to the inner skirt. Thus, a malicious individual can not use a rotation of the outer portion of the closure device to try to force the locking members.

Advantageously, the outer skirt comprises a cooperating tapping, in protective position, with a thread formed on the outer wall of said first end of the housing. Thus, the anti-theft protection system is further strengthened.

The protection system comprises a housing base of said magnetic element, intended to cooperate with a magnetic unlocker. In one embodiment, the base has a tubular shape. Thus, the base is adapted to the use of standard textile unlocker. In another embodiment, the base comprises an unlocking portion having two parallel opposite side faces and two symmetrical side faces forming a cylinder. Thus, the system is compatible with several types of magnetic unlocker.

In one embodiment, the base has longitudinal grooves cooperating, in the protective position, with longitudinal grooves of the inner wall of said first end. Thus, the game between the different elements of the device is reduced so that the system is much more difficult to force.

In a first embodiment, the locking member is a ring rotatable relative to the base between a locking position and an unlocked position, said cooperating metal element, in its locking position with said ring. movable so as to prohibit the return of the movable ring to its unlocked position.

In this mode, the movable ring comprises at least one movable locking pin in a guide and immobilizing groove formed on the first end of the housing. In addition, the system comprises a return means reminding the movable ring to its unlocked position. Furthermore, the metal element is a flyweight comprising a cooperating head, in locking position, with an abutment surface of the movable ring, and the abutment surface comprises a recess for housing the head of the counterweight. In a second embodiment of the invention, the first end of the housing has a notch and the closure device comprises at least one movable locking pin between an unlocked position and a locking position in which it cooperates with said notch, said cooperating metal element, in its locking position with the pin so as to prohibit its return to its released position. The closure device comprises means for returning the pin to its released position. In addition, the closure device comprises a push button arranged to drive the pin from its unlocked position to its locking position. Preferably, the first end of the housing has two notches and the closure device comprises two locking pins.

Advantageously, the closure device comprises an electronic detection tag.

In one embodiment, the system includes an alarm.

Advantageously, the system comprises a plurality of movable metal elements, under the influence of a magnet, between at least one locking position of the locking member in its locking position and a release position in which the locking member is unlocked.

The closure device 2 is engaged in the opening 4 in a longitudinal direction I to the housing to its protective position.

Furthermore, the closure device comprises magnetic locking means for locking and immobilizing the closure device 2 in the protective position, on the elongated housing 1.

The closure device 2 further contains a detection tag 9 may be identified by a detection device, such as gantries located at the outlet of stores, for example, to trigger an alarm during the crossing of the portico. The detection tag may in particular be an RF tag, circuit or coil, a RFID tag, circuit or coil, an RF ferrite, an electromagnetic tag, or a magnetoacoustic tag or ferrite.

In a non-illustrated embodiment of the invention, the closure device 2 comprises an alarm, means for activating and deactivating the alarm and a magnetic field-sensitive element of the type with a flexible blade switch. arranged to trigger the alarm when said sensing element is subjected to a magnetic field. In addition, the alarm circuit comprises a delay for shifting the triggering of the alarm by said sensitive element by a determined duration. The alarm deactivation means are activated when the locking member is in its release position and they then inhibit the alarm when it has been deactivated for the determined duration. Thus, when a magnet is approached to the metal element and the locking member is not released within a predetermined time, an alarm is triggered so as to warn the supervisory agents and / or the personnel of the surface sale of an attempted break-in.

In one embodiment of the invention, the closure device further comprises means for communicating the alarm signal to a remote device. Thus, an alarm signal can be directly transmitted to the monitoring station in order to try to intercept the fraudster as soon as possible.

Furthermore, it may also be provided that the anti-theft system according to the invention is provided with means for hanging on a presentation pin. These hooking means may in particular be constituted by a cord connected to the housing or a part integral with the housing and having a passage hole of said pin.

Figures 1 to 3 show a first embodiment of the invention.

In this embodiment, the body of the closure device 2 comprises a base 10 and a ring 5. The ring 5 is rotatably mounted on the base 10 between a released position and a locking position.

To do this, the base 10 comprises a central axis 11, shown in Figure 2, wherein is formed a tapped bore and the ring 5 has a lower wall 12 having a bore. The central axis 11 is inserted into the bore of the lower wall 12 and a threaded screw 13, inserted in the threaded bore, makes it possible to fix a washer 14 cooperating with the bottom wall 12, so that the ring 5 is maintained. on the base 10. On the other hand, the ring 5 comprises a shoulder 15 coming to rest on a receiving surface 16 of the base 10.

The ring 5 has an internal cavity 17 for housing the detection label 9. In the embodiment shown, the detection label 9 is an electromagnetic ferrite. The internal cavity 17 also allows the passage of the washer 14 and the fixing screw 14 of the ring 5 on the base 10.

A shutter 18 closes the internal cavity 17 of the ring 5. In the embodiment shown, the internal cavity 17 of the ring 5 comprises a support membrane 19 of the ferrite 9 provided with an orifice for receiving an end ferrite

9 and the shutter 18 has a cell for receiving the other end of the ferrite 9. Thus, the ferrite 9 is properly held inside the ring 5.

Furthermore, the movable ring 5 comprises an inner skirt 20 which has a shape complementary to an inner wall of the first end 3 of the housing 1 and comes, in the protective position, to fit into the housing at level 1 of its first end 3. The insertion of the inner skirt 20 inside the casing 1 makes it possible to increase the bending strength of the junction of the casing 1 with the closure device 2. Advantageously, the portion of the ring 5 in the housing 1, in the protective position has a height greater than 0.5 cm, and preferably greater than 1 cm.

The movable ring 5 also comprises an outer skirt 21 having a shape complementary to an outer wall of said first end 3 of so as to cover said first end 3. The outer skirt 21 carries, on its inner wall, locking pins 22 which are movable in grooves 23 for guiding and immobilization formed on the first end 3 of the housing 1.

The guide grooves 23 have an L-shaped profile having a first portion 23a extending longitudinally so as to allow the locking pins 22 to be guided during the insertion of the closure device 2 along the longitudinal direction of the housing 1 and a second locking portion 23b extending perpendicularly to the first portion 23a for guiding the pins when the ring 5 is rotated, for example by a quarter of a turn, between its released position and its locked position. Thus, when the pins 22 are in the second portion 23a, the ring 5 is in the locking position.

The elongate housing 1 has an annular shoulder 24 against which the upper edge of the outer skirt 21 abuts in its protective position. In addition, the base 10 has an annular shoulder 25 cooperating with the lower edge of the inner skirt 21. These shoulders 24, 25 can prevent the introduction of an object capable of forming a lever, such as a blade between the outer skirt 21 and the housing 1 or between the outer skirt 21 and the base 10.

The closure device 2 further comprises a return means 26 which is housed in the base 10 and is arranged to return the ring 5 to its released position. The return means 26, shown in FIGS. 1 and 2, is a torsion spring having a first end secured to the base 10 and a second end secured to the ring 5.

The base 10 also comprises a housing of a flyweight 8 metal. Said flyweight 8 is movable in the longitudinal direction of the housing 1 between a locking position of the ring 5, in which it prevents the ring 5 from returning to its unlocked position and a release position in which the movable ring 5 is unlocked. The weight 8 cooperates with a spring 27 which reminder to its locking position. The lower wall 12 of the ring 5 comprises a passage opening of the head 28 of the flyweight 8. Thus, in the locking position, the head 28 of the flyweight 8 cooperates with a border 29 of this orifice, forming stop, so as to prevent the return of the locking ring 5 to its unlocked position.

To drive the flyweight 8 to its release position, a magnet must be approached near the lower end of the base 10 so as to exert a magnetic attraction in a substantially longitudinal direction to the housing 1.

In the embodiment shown, the base 10 comprises a substantially tubular portion whose dimensions are arranged to allow the use of a standard textile release to drive the flyweight 8 to its release position.

In addition, the base 10 comprises, on its inner end being inserted into the housing 1, longitudinal grooves 30a, 30b, 30c cooperating, in the protective position, with longitudinal grooves 30d, 30e, 30f of the inner wall of said first end 3 of the housing 1.

Figures 3a to 3d illustrate the closure device 2 between its locking position and its unlocked position.

In the locked position, shown in Figure 3a, the locking pins 22 are arranged in the second portion 23b, locking grooves 23. The weight 8 has a head 28 which cooperates with an abutment surface 29 of the lower surface 12. The abutment surface 29 further comprises a recess for housing the head 28 of the flyweight 8.

To unlock the closure device, the ring 5 must be rotated, in the opposite direction to its unlocking direction, to a locking disabling position so as to clear the head 28 of the weight 5 of the recess ( see Figure 3b). Simultaneously, the base 10 must be positioned on a suitable unlocker, so as to drive the flyweight 8 to its release position.

In this case, as soon as the weight 8 reaches its release position, the spring 6 recalls the locking ring 5 to its unlocked position, illustrated in Figure 3c. The pins 22 are thus in the longitudinal portion 23a of the grooves 23 and the housing 1 and the closure device 2 can thus be separated by a longitudinal translational movement of the housing 1 relative to the closure device 2 (see Figure 3d). It will also be noted that, in this position, the head 28 of the weight 8 is held against the lower face of the bottom wall 12 so that the weight 8 is held in its released position.

On the contrary, to lock the closure device 2 on the housing 1, the closure device 2 is inserted into the elongate housing 1, so as to move the locking pins 22 in the longitudinal portions 23a of the grooves 23 until at the stop. Then, the locking ring 5 is pivoted to its locking position. During this pivoting movement, the weight 8 is in vis-à-vis the passage opening of the head 28 feeder 8, formed in the inner wall 12, so that the weight 8 comes in blocking position and prohibits the movement of the ring 5 to its unlocked position.

Figures 4, 5a, 5b, 6a and 6b show a second embodiment of the invention.

In this embodiment, the closure device 2 also comprises a base 10 and a ring 30 mounted movably, free in rotation, with respect to said base 10.

30 to immobilize the shutter 18 on the ring 30. The ring 30 forms an inner skirt 33 which has a shape complementary to an inner wall of the first end 3 and comes, in the protective position, to fit into the housing 1. As for the previous embodiment, the insertion of the inner skirt 33 inside the casing 1 makes it possible to increase the bending strength of the system.

In the embodiment shown, the base 10 has an upper portion forming an outer skirt 34 and a lower portion 35.

The cylindrical outer skirt 34 has a shape complementary to an outer wall of said first end 3 so as to cover said first end 3. In addition, the outer skirt 34 covers, in the protective position, the notches 36a, 36b of locking formed on the housing 1, intended to receive the pins 6, 7 in the locking position.

The outer skirt 34 is mounted free in rotation, or crazy, relative to the ring 30 which comprises the locking members 6, 7. Thus, a malicious individual can not use the rotation of the outer portion of the closure device 2 to try to force the locking members 6, 7 of the closure device 2.

In addition, in the protective position, the upper edge of the outer skirt 34 abuts against an annular shoulder 24 of the housing 1. This shoulder 24 contributes to the inviolability of the system by preventing the introduction of a blade between the outer skirt 34 and the housing 1.

Furthermore, the lower portion 35 of the base 10 has a particular shape. Indeed, this portion 35 has two parallel opposite side faces 36 and two symmetrical lateral faces 37 forming part of a cylinder whose axis of revolution corresponds to the longitudinal axis I of the housing 1. Thus, this portion 35 is at the once adapted to allow the use of a standard textile unlocker, circular, or a particular unlocker, parallelepiped shape. In addition, the base 10 has a housing of a detection label 9 which is an electromagnetic ferrite in the mode shown.

The locking means comprise two pins 6, 7 of locking.

Each locking pin 6, 7 is supported by a slider 38, 39 movable in translation on a guide rail 40, 41 formed on the plate 31 so as to allow the movement of the locking pins 6, 7 between their unlocked position and their position. locking position in which the pins 6,7 are introduced into notches 36a, 36b of the housing 1. In addition, the locking pins 6, 7 are held in orifices 42 formed in the ring 30. When the closure device 2 is in the protective position on the housing, the orifices 42 formed on the ring 30 coincide with the notches 36a, 36b formed in the first end 3 of the housing 1.

A push button 43 is also movably mounted on the plate 31 between a rest position and an activation position in which it cooperates with the bends 38, 39 so as to drive the pins 6, 7 to their position. locking. The push-button 43 has a slit sliding on a rail, so as to allow the translational movement of the push-button 43.

Furthermore, the ring 30 has an orifice 44 for passing the end of the push-button 43. In addition, the casing 1 comprises a longitudinal slot 45 allowing the passage of the push-button 43 when the closure device 2 The push-button 43 has an element 43a having inclined bearing surfaces cooperating with inclined, symmetrical surfaces 46, 47 of the bends 38, 39 so as to push said bends 38, 39 towards their locking position.

In addition, the base 10 also comprises an axial housing of the weight 8 locking metal. Said flyweight 8 is movable in the longitudinal direction of the housing between a locking position, in which it prevents the locking pins 6, 7 from returning to their unlocked position and a release position in which the locking pins 6 7 are Unlocked. The weight 8 cooperates with a spring 27 which reminder to its locking position.

Figures 5a, 5b, 6a and 6b illustrate in detail the operation of the magnetic locking means.

In the locking position, shown in Figures 5a and 6a, the locking pins 6 7 are introduced into the notches 36a, 36b of the housing 1 so as to immobilize the closure device 2 on the housing 1.

The flyweight 8 is held in a housing of the base 10 and the spring 27 recalls the flyweight 8 to its locking position. When the weight 8 is in its biocage position, it protrudes through a central hole of the plate 31 and is inserted between the two slides 38, 39 so as to prevent their return to their unlocked position. The slides 38, 39 each comprise a shoulder 48, 49 cooperating, in this position, with the body of the weight 8 and a slight return of material retaining the head 28 of the weight 8.

Furthermore, in the locking position, the element 43a, V-shaped and having inclined bearing surfaces is disposed between the two slides 38, 39.

To unlock the closure device 2, the base 10 must be positioned on a suitable unlocker, so as to cause the flyweight 8 to its release position.

When the flyweight 8 is in its release position, biasing means to recall the pins 6, 7 locking to their unlocked position. These return means here consist of compression springs 50, 51 mounted on the pins 6, 7 of locking and cooperating with the inner wall of the ring 5. In addition, the inclined shape of the bearing surfaces 46, 47 of the sliders 38, 39 and the V-shaped member 43a of the pushbutton 43 allow the springs 50, 51 to drive the push button 43 to a rest position and the slides 38, 39 to their unlocked position (see Figure 6b).

In the unlocked position, the head 28 of the weight 8 cooperates with the shoulders 48, 49 of the slides 38, 39 and the weight 8 is maintained in its release position (Figure 5b).

On the contrary, to lock the closure device 2, the push button 43 is slid to reach its activation position in which it pushes the slides 38, 39 to their locking position; the locking pins 6, 7 are then, in the locking position, in the notches 36a, 36b.

Taking advantage of the spacing between the sliders 38, 39, the head 28 of the feeder 8 is then introduced between the sliders 38, 39 under the action of the spring 27 biasing the weight 8 to its locking position. The closure device 2 is then locked on the housing 1.

Figures 7, 8a, 8b, 9a and 9b show a third embodiment of the invention.

The third embodiment is substantially identical to the second embodiment. However, the outer skirt 34 has a tapping 52 on its inner wall while the first end 3 of the housing 1 has a thread 53 for cooperating with the tapping of the outer skirt 34. In addition, the outer skirt 34 has two notches 54a , 54b blind and coming opposite the notches 36a, 36b of the housing 1 when the outer skirt 34 is screwed onto the first end 3 of the housing 1. Thus, in the locking position, the pins 6, 7 are introduced in the notches 54a, 54b of the housing 1. Thanks to the threading and locking of the outer skirt on the first end of the housing 1, the anti-theft protection system is further reinforced.

Figures 10a and 10b show a fourth embodiment of the invention. The closure device shown in these figures is substantially identical to the device described in relation with FIGS. 4, 5a, 5b, 6a and 6b.

However, this device is equipped with a second and a third additional metal elements. The second and third metal elements are movable in opposite directions, perpendicular to the longitudinal direction I of the housing, between a locking position of the metal weight 8 in its locking position of the locking member and a release position of said 8. Thus, in this embodiment, to unlock the locking member, three magnets must be simultaneously placed in appropriate positions to move the second and third metal elements to their release position of the metal weight 8 d ' on the one hand, and on the other hand, to move said metal weight 8 towards its release position. The security of the closure device is thus reinforced.

According to the first variant, shown in Figure 10a, the metal elements are flyweights 57a, 57b biased to their locking position of the weight 8 by springs 58a, 58b. The closure device comprises housings for guiding the displacement of said weights 57a, 57b and for housing the springs 58a, 58b.

When the heads of the weights 57a, 57b are engaged in the lateral grooves 59a, 59b, the weight 8 is held in its locking position.

In order to unlock the locking member, three magnets must be arranged at each of the locations 61a, 61b, 61c.

It will be noted that in FIG. 10a, one of the flyweight 57a is shown in a release position while the other flyweight 57b is shown in a locking position of the flyweight 8 in the locking position of the organ locking. It will also be noted that, in the arrangement of the weights shown in FIG. 10a _1, the magnetization power necessary to drive the weights 58a, 58b towards their release position is greater than if it were to drive this weight. 58a, 58b alone, out of this particular context.

In the second variant, shown in Figure 10b, the second and third metal elements are flexible metal blades 60a, 60b. The flexible metal blades are movable between a release position (see the blade 60a of Figure 10b) and a blocking position of the weight (see the blade 60b of Figure 10b). In the locked position, the end of the blades 60a, 60b engage in the lateral grooves 59a, 59b formed in the feeder 8 so that the weight 8 is locked in the locking position of the locking member.

Furthermore, it will be noted that it is conceivable to provide alternative embodiments in which the closure devices described in relation to FIGS. 1 to 3, and 7 to 9, are equipped with second and third metallic elements. , according to one of the two variants presented above, in order to lock the feeder 8 in its locking position of the locking member.

Of course, an unlocker adapted to the closure device 2 presented above, will present two additional magnets arranged to move the weights 57a, 57b or the metal blades 60a, 60b to their release position.

According to one embodiment of the invention, shown in Figures 11 and 12, the housing 1 is formed of two half-shells 55a, 55b hinged to one another by means of a hinge 56. Thus , the housing 1 can be opened so as to allow the introduction of an object to be protected whose shapes and dimensions would not allow it to be introduced through the opening 4 of the housing.

FIG. 11 represents the housing 1 in the closed position and the device 2 of closing of the orifice is engaged in the orifice 4 of the casing 1 so as to protect the article contained in the casing 1. When the temporary closure device is engaged in the orifice 4, the casing 1 can no longer be opened . Indeed, the two ends of the half-shells bordering the orifice 4 are held between the inner skirt 33 and the outer skirt 34 so that the housing 1 can not be opened.
