Description

HOUSING WITH LOCKING SLIDE AND IMMOBILIZATION IN

The present invention relates to the field of secure packaging. More particularly, the present invention relates to a housing formed of two shells closing on one another and unlocking by means of a dedicated tool so as to prevent the opening of the housing other than with a dedicated unlocking tool . In particular, such a housing is intended to contain an electronic device, more particularly a mobile phone.

There are secure cardboard housings with adhesive tape forming a seal, allowing a buyer to ensure that it has not been opened. Once opened, the lid of the cardboard can be closed reversibly, most often thanks to tabs getting stuck in housing. The box can be kept by the customer to protect the device contained. However, when the case is exposed in the store, it is easy to remove the adhesive to take the device and then close the case at the point of sale, in order to steal the device. The case remaining in the rack, it is more difficult to detect such a flight, especially when this detection is based on a detectable element attached to the housing.

The technical problem that the invention aims to solve is therefore to further secure the contents of an exposed housing at a point of sale.

For this purpose, a first object of the invention is a housing, in particular intended to contain a telephone, in particular a mobile telephone, this housing comprising:

a first shell and a second shell closing one on the other so as to close the housing by rendering its contents inaccessible,

- A slider mounted to move in translation on the first shell, comprising at least one latching member, and operable from outside the closed housing so as to be positioned by translation in a first, a second or a third position.

In this case, the first shell, the second shell and the attachment member or members are arranged so that when the case is closed: at least one hooking member is hooked to the second shell when the slide is in the first position, thus opposing the opening of the housing,

- At least one fastening member is attached to the second shell when the slide is in the second position, thus opposing the opening of the housing, - or the hooking members are free when the slide is in third position , thus allowing the opening of the housing.

This box further comprises:

a device for locking the slider on one of the hulls in first position, operable only by means of a dedicated tool from the outside of the case when this case is closed,

first reversible immobilization means of the slide in second position,

second reversible immobilization means of the slider in third position.

Thus, by means of a common part, namely the slide, this housing allows both the secure locking of the housing and the reversible closure of the housing once it is unlocked.

Without the dedicated tool, except to destroy the case, which is not discreet, it is very hard, if not impossible to open the case and access its contents. When it is on a store rack, you can not take its content discreetly. Moreover, by placing inside the housing a detectable element, such as an RFID tag, it is difficult to leave the store without actuating the detectors.

In addition, once the housing is unlocked and, if there is one, the RFID tag deactivated or removed, the buyer can leave with the housing and its contents, allowing it to protect the device contained in the housing. With reversible immobilization in the second or third position, the buyer can open and close the housing several times and manually.

The housing according to the invention may optionally have one or more of the following characteristics:

the immobilizing means are arranged so that immobilization according to the second position or according to the third position is done by reversible clipping between a projecting element and an immobilization housing; it is a simple way to reversibly hold the slider in the second or third position;

the first immobilizing means and the second immobilizing means respectively comprise a first immobilization housing and a second immobilization housing formed on a fixed immobilization wall of one of the shells, and wherein the slide comprises a protruding element adapted to be housed in the first immobilization housing or in the second immobilization housing according to the slider is positioned respectively in second position or in third position; in other words, the salient element is here common to the first immobilization means and to the second immobilization means, and allows housing in the corresponding immobilization housing; it is a simple way of indexing the positions according to the positioning of the dwellings;

the first immobilization housing and the second immobilization housing are formed respectively by a first portion and a second portion of a through-hole of the immobilizing wall, these first and second portions being separated from one another; other by a narrowing of the periphery of this through hole, the projecting element being arranged through the through hole when the slide is in the second position or third position and being able to pass from one portion to another through the narrowing by elastic deformation between the narrowing and the projecting element; it is a simple embodiment allowing the reversible snap on one side or the other of the narrowing, without the projecting element coming out of the through hole, so that it keeps the slide in one either of the positions only because the projecting element is blocked in the through hole; this is all the more effective if the projecting element is metallic, such as a rod;

the locking device is mounted on the slide; this facilitates the realization of the hulls;

- The locking device comprises a movable member between a locking position, wherein the movable member is housed in a locking housing, and an unlocking position, wherein the movable member is outside of the locking housing, one of the locking device and the locking housing being secured to the slide and the other of the locking device and the locking housing being integral with one of the shells, so that locking position the movable member locks the slide on this shell; it is a simple means of realization allowing a strong locking, conferring a great resistance to an opening in force;

the locking device comprises an elastic return member arranged such that when the movable member is moved towards its unlocking position, the elastic stress of the return member increases and thus generates a restoring force of the member mobile to its blocking position; there is thus a better hold in locking;

the movable member is a magnetic or magnetizable element or is attached to a magnetic or magnetizable actuatable member, the movable member or the movable member and the actuatable member being arranged to be driven to the unlocking position by a tool magnetic dedicated from the outside when the case is closed; this allows easy and safe operation;

the slide slides in translation along the immobilizing wall, the locking housing being formed in this immobilizing wall and aligned with the first immobilization housing and the second immobilization housing, the projecting element forming the mobile organ; thus, the housing allows with the same movable member to lock in one position and immobilize in two other positions; this simplifies the housing;

the locking device is arranged to lock the slide on the first shell; this allows to give more degrees of freedom in the design of the housing, especially as to the arrangement of the first shell relative to the second shell, the slide is locked on the shell on which it is mounted mobile;

the slide is guided in translation by:

at least one groove integral with the slider or the first shell, and

at least one rail secured respectively to the first shell or the slider and sliding in this groove; this allows a better positioning of the slide; to improve this positioning, the housing may comprise a combination of groove and rail on each side of the slider;

the slider is operable from outside the closed housing so as to position itself by translation in a fourth position, in which the rails are disengaged from the grooves and in which the slider is opposite a mounting opening in the housing, the mounting opening being arranged to allow the passage of the slider outwardly of the housing; the assembly of the housing is thus facilitated;

- The housing comprises a protective housing and a compartment separated from each other by a partition wall, the protective housing being intended to receive said inaccessible content, the slider moving in translation in the compartment, and the compartment presenting the mounting aperture; the inaccessible content can be placed in the housing without paying attention to interfering with the slider;

the immobilizing wall is mounted on and transversely to the partition wall, the immobilizing wall separating the compartment into a first part and a second part, the first part comprising the slide, the immobilizing wall comprising a passage through which the fastening members, which open into the second part, the second part receiving, when the case is closed, complementary means integral with the second shell, the passage, the fastening members and the complementary means being arranged in such a way as to that the catching members are able to translate along the passage when the slide passes from one position to the other and so that the attachment of the fastening members to the second hull is carried out by the attachment to these complementary means; this simplifies the realization of the housing with a common wall for indexing according to the three positions;

the immobilizing wall is arranged vis-à-vis the mounting opening; thus, one can mount the slide bearing against the immobilizing wall, which can then serve as a guide to mount it mobile in translation, in particular, when it is the case, to engage the rail or rails in the or the corresponding grooves; the hooking members are arranged and cling to the second shell inside the closed housing; the securing of the housing lock is reinforced.

Other features and advantages of the invention will appear on reading the detailed description of the following nonlimiting examples, for the understanding of which reference will be made to the appended drawings, among which:

Figure 1 is a perspective view from the front and from the bottom to the top of an embodiment of a first shell of a housing according to the invention;

Figure 2 is a rear perspective view and from the bottom to the top of a second shell fitting into the first shell of Figure 1 to close the housing example;

Figure 3 corresponds to Figure 1 with the representation of the four positions of a slide of the housing example;

Figures 4 and 5 are perspective views of the slide of Figure 3 with its cover, respectively viewed from the front and back;

Figure 6 shows a schematic section of the slide in Figure 4, in a transverse plane perpendicular to the front and rear walls of the housing;

Figures 7 and 8 are perspective views from behind and respectively from top to bottom and from bottom to top; they illustrate the mounting of the slide and its cover according to Figure 5 at the rear of the first shell of Figure 1;

Figure 9 illustrates the assembled housing.

Figures 1 and 2 respectively illustrate a first shell 1 and a second shell 2 which once assembled form the outer walls of an exemplary housing according to the invention.

The first shell 1 is in this example deeper than the second shell 2, but this is not limiting.

This first shell 1 defines an interior volume comprising a protective housing 8 for containing an electronic device, in particular a mobile phone.

The assembled box B is visible in FIG. According to the invention, as in this example, the housing B can be arranged to be suspended in a rack, in particular by a suspension means, such as a ring 9, arranged at the top of the first shell 1.

In the illustrated example, the terms "up", "down", "under", "above", "below", "down", "up", "forward", "back", "front", "behind" "," Vertical "," transverse "refer, unless otherwise indicated, to the orientation of the case hanging from its ring 9.

This first shell 1 can, as here, be the rear shell of the housing B, when the housing is exposed suspended from its ring 9. Thus in Figure 1, we see the inner face of the rear wall 38 of the first shell 1.

In this example, a transverse internal partition, called partition wall 7, separates this interior volume in two: the protective housing 8 above the partition wall 7 and a compartment below this partition 7.

As here, the first shell 1 may comprise a step 37, so that the protective housing 8 comprises a lower volume deeper than a high volume. This allows for example to place accessories in the low volume and to place a flat mobile phone in front of the accessories and against both these and the inner face of said rear wall 38 in the high volume.

The first shell 1 is delimited by the rear wall 38 and four edge walls, these edge walls comprising: a bottom wall 33, a high wall 35, a left wall 34 and a right wall 36.

The second shell 2 makes it possible to close the housing B. It comprises a front wall 20 of the housing, the internal face of which can be seen in FIG.

According to the invention, as here, this second shell 2 can form a cover of the housing B. In the illustrated example, this second shell 2 fits snugly between the edge walls 33 to 36 of the first shell 1, the internal face of said front wall 20 coming opposite the internal face of said rear wall 38.

Here, the second shell 2 comprises a bottom wall 23, a left wall 24, a right wall 26 and a high edge 25.

As here, the high edge 25 can be arranged to be housed behind a tongue located at the top of the upper wall 35 of the first shell 1 and facing the protective housing 8. This tab is not shown on these drawings. Once this top edge 25 is housed behind this tongue, it forms with this tongue an articulation allowing the said front wall 20 to be folded towards the said rear wall 38. The high edge 25 may comprise a recess 27 of shape complementary to the tongue to facilitate its housing.

For example, during said folding down the lower wall 23 of the second shell 2 is slid against and above the lower wall 33 of the first shell 1, the left wall 24 of the second shell 2 is slid against and to the right of the left wall 34 of the first shell 1, and the right wall 26 of the second shell 2 is slid against and to the left of the right wall 36 of the first shell 1.

The lower wall 23 of the second shell 2 is wider than the other walls

24, 26 of the second shell 2, so as to be housed in the compartment.

Once the housing is closed, said front wall 20 is flush with the front edges of the edge walls 33 to 36 of the first shell 1. The contents of the housing B is in this case inaccessible, that is to say that it can not be taken through the housing, or that it can not be taken without opening or breaking the latter.

To secure the closure of this housing B, the latter comprises a slider 4, detailed in FIGS. 4 to 6, and represented according to four predetermined positions Pi, P2, P3, P ₄ represented in FIG.

In general, this slider 4 is mounted to move in translation on the first shell 1 and is arranged so as to be able to hook to the second shell 2, when it is in a first position Pi and when it is a second position P2. This attachment allows to oppose the spacing of the shells 1, 2, one of the other.

In the example illustrated, the slider 4 comprises two attachment members 41, 42 whose ends, when the slider 4 is in the first position Pi or second position P2, are housed in front of complementary means, such as the vertical projections 21, 22 illustrated. The attachment members 41, 42 thus retain the second shell 2 by its vertical projections 21, 22.

The hooking members 41, 42 and the vertical projections 21, 22 are arranged so that, when the slider 4 is in the third position P3:

the fastening members 41, 42 are arranged on either side of the right vertical projection 22 (thus shown on the left in FIG. 2), and - The left coupling member 41 is between the vertical projections 21, 22. Thus, the attachment members 41, 42 are next to the vertical projections 21, 22 and are free. They therefore no longer retain the second shell 2, thus allowing the separation of the second shell 2 of the first shell 1, thus the opening of the housing B.

Here, the compartment is separated by a vertical internal partition 10 into a first portion 31 and a second portion 32, hereinafter respectively the rear portion 31 and the front portion 32. In FIG. 1, only the front portion 32 is visible, the rear portion 31 being behind the vertical internal partition 10.

The slider 4 is housed in the compartment, which makes it possible to separate it from the protective housing 8. More particularly, it is housed in said rear part 31.

In FIG. 3, the slider 4 is represented according to the orientation it has when it is mounted on the first shell 1. In order to better visualize the slider 4, the slider 4 is shown in FIG. 3 outside the compartment and aligned with the determined positions P ₁ , P ₂ , P ₃ , P ₄ , the dotted lines indicating the alignment of a point of the slider 4 and of a point of the vertical internal partition 10 according to the corresponding position. Similarly, the reference "4" of the slide is, in Figure 3, followed by the reference of its position in parentheses.

The passage between these determined positions Pi, P2, P3, P ₄ is by translation.

In this example, these positions are aligned in the following order: fourth position P ₄ , first position Pi, second position P2, third position P3.

The vertical internal partition 10 comprises a passage 30, visible in FIG. 7, through which the fastening members 41, 42 pass. The end of these fastening members is thus housed in said front portion 32. This passage 30 is arranged so that when the slide 4 translate in the rear portion 31, the ends of these attachment members 41, 42, translate in the front portion 32, to come or not to hang on the vertical projections 21, 22.

Here, to facilitate the translation, inside the rear portion 31, the first shell 1 comprises two pairs of rails 18, 19. For each pair, one of the rails 18, 19 is arranged on the inner face of the low wall 33 of the first shell 1 and the other rail 18, 19 is arranged on a lower face of the partition wall 7. The slide 4 comprises two pairs of grooves 44, 45 at the top and bottom, arranged so that the slide is mounted in the first shell 1 by insertion of the rails 18, 19 in these grooves 44, 45, and so that that these rails guide the slide 4 according to the translational movement in the compartment. These rails 18, 19 extend here vertically and transversely.

In the illustrated example, these rails 18, 19, and the slider 4 are also arranged so that the slider slides against and / or along the vertical internal partition 10.

In this example, the vertical internal partition forms an immobilizing wall 10, against which the slider 4 can also:

lock in the first position Pi, and

stop in second position P2 and in third position

P ₃ .

The position Pi of this locking and the two immobilization positions P2, P3 are indexed on the immobilizing wall 10 respectively by a locking housing 1 1 and a through hole 1 6.

The slider 4 comprises a locking device 6 with a projecting element 43, here formed by a movable member 43 between a locking position, illustrated in these Figures 3 to 6, and an unlocking position, not shown.

In this example, the movable member 43 is a retractable rod 43, mounted movably between the locking and unlocking position inside a cylindrical tank 60 of the locking device 6. This tank 60 is mounted in a housing home, which is formed in the slider 4 and which is behind a front face 47 of the slider 4. This front face 47 comprises a hole through which the rod 43 is adapted to retract and deploy .

The tank 60 here comprises a resilient return member 63 arranged so that when the rod 43 is retracted, thus here moved to its unlocking position, the elastic stress of the return member 63 increases and generates a restoring force. of the rod 43 to its locking position. This return member is here a spring 63 with turns, which is surrounded on one side around a rear end 62 of the rod 43 and the other placed against the bottom of the tank 60. According to one embodiment of the invention, as here, the rod 43 is a magnetic or magnetizable element. It can, as here, include a guide disc 61, here provided by material with this rod 43. In this example, it serves as a guide along the tank 60 and also stops, which abuts against the front face 47 of the slider 4 when the rod 43 is deployed, in particular under the effect of the restoring force.

In this example, the rear face of the slider 4 comprises a shank 46, in which the rear of the trough 60 is housed and is flush with the shank edges 46. Here, this allows the positioning of a specially dedicated tool, comprising a complementary impression of this shaft. For example, this tool comprises a magnetic field generator inside the cavity and therefore inside the tank 60, allowing, when the tool is activated, to drive the rod 43 towards the bottom of the tank. tank, thus compressing the spring 63. When the magnetic field is withdrawn, the spring 63 recalls the rod 43 towards its deployed position, illustrated in FIG.

When the slide 4 is in the first position Pi, the rod 43 is housed in and passes through the locking housing 1 January. Without the magnetic tool, it is not possible to slide the slide 4, and thus to shift the fastening members 41, 42 relative to the vertical projections 21, 22. The casing B is locked, securing the contents. of it. It is in this configuration that the box B is used to expose its contents.

The housing B may be rigid thermosetting plastic. It can be transparent to leave its visible content, or opaque to hide it. It is also possible to make only one of its hulls opaque, including the hull back. In this example, at least the second shell 2 is transparent.

Alternatively, the first shell 1 may be intended to be exposed to the front and the second shell 2 may be intended to be exposed to the rear. The first shell 1 may for example be transparent.

When it is desired to unlock the housing B, especially once the product purchased, the seller can retract the rod 43 in the body 40 of the slide by means of the dedicated tool. The rod 43 then leaves the locking housing January 1, thus driving the slide 4 on the side, here on the right. The rod 43 is then in abutment against the rear face of the immobilizing wall 10 under the effect of the restoring force.

It is then possible to stop the action of the magnetic field and to move the slider 4 until the rod 43 comes opposite the through hole 1 6, the rod 43 then being housed in this through hole 1 6 under the effect of the restoring force.

The housing B is thus unlocked. However, it remains locked in closing, the slider 4 opposing its opening. Nevertheless, the through hole 16 corresponds to an unlocking because the slider 4 is now reversibly movable, ie without the dedicated tool, between the second position P2 and the third position P3.

In this example, this through hole 1 6 is delimited by an edge which forms the periphery. This edge comprises a narrowing 17, in which this through hole 1 6 forms a smaller width. The through hole 1 6 thus comprises a first portion 12 and a second portion 13 arranged on either side of the constriction 17.

The first portion 12 is arranged between the blocking housing 1 1 and the second portion 13.

After unlocking, the rod 43 remains blocked through the through hole 1 6, except to use the magnetic tool.

According to the invention, as here, the narrowing 17 may have a width less than that of the rod 43 and may be arranged so that it can deform by pressing the sides of the rod 43 against it, so that the passage of the rod 43 of a portion 12, 13 to the other through the narrowing 17 is by deformation of the narrowing. To achieve this passage, the slider 4 is driven on one side or the other. This exemplary embodiment makes it possible to move the rod 43 by reversibly snapping a portion 12, 13 to the other.

The narrowing 17 nevertheless makes it possible to maintain the slide 4 in the second position P2 or in the third position P3 in the absence of force on the slide 4, the rod 43 remaining in the first portion 12 or in the second portion 13.

Thus, the first portion 12 and the rod 43 form first reversible immobilization means of the slide 4 in second position P2, and the second portion 13 and the rod 43 form the second reversible immobilization means of the slider 4 in the third position P3.

Once the housing B unlocked, the purchaser of the product can thus freely lock the housing or unlock by simply actuating the slider 4 to respectively its second position P2 or its third position P3. The slider can simply be actuated from outside the housing B. This actuation can be manual. The box B thus forms the packaging and / or the content protection box, such as the mobile phone. It can eventually be stored and taken out throughout its life.

The first shell 1 here comprises on its rear face a mounting opening

14 giving access to the rear portion 31 of the compartment. This mounting aperture

14 is closed by a cover 5.

This cap 5 may comprise a transverse sliding lumen 50 through which the barrel 46 passes and the length of which is arranged so as to allow the slider 4 to slide from the first position Pi to the third position P3.

Thus the shaft 46 is not only accessible to the magnetic tool from outside the closed housing but also operable on one side or the other in translation, in particular manually, so as to move the slide 4 and position it by translation according to the first, the second or the third position Pi,

Before the housing is used, the assembly of the slider 4 in the first shell 1 is performed by mounting the slider through the mounting opening 14, which is arranged vis-à-vis the immobilizing wall 10 .

During this assembly, the slider 4 is positioned in a fourth position P ₄ with its front face 47 vis-à-vis the rear face 39 of the immobilizing wall

10. The rod 43 is then pressed against the rear face 39 of the immobilizing wall 10.

According to the invention, as in this example, the length of the portion of the rod 43 out of the front face 47 of the slider 4 in the deployed position may be close to or equal to the distance between the grooves 44, 45, and the rails 18 19 when the rod 43 is deployed and bears on the rear face 39 of the immobilizing wall 10. Thus, it is possible by pressing the slide 4 against the immobilizing wall to retract the rod 43 in the tank 60 and guide the slide 4 against this immobilizing wall 10, until the grooves 44, 45 engage with the rails 18, 19. During this sliding, the rod 43 remains retracted against the immobilizing wall 10, until coming to face the locking housing January 1, where it then comes under the effect of the restoring force.

There is thus a guide assembly to the first position Pi through the return member 63 and the immobilizing wall 10.

According to the invention, as in this example, a clearance 49 can be provided between the right groove 44 and the left groove 45 on the same side, so as to let between these grooves 44, 45 the left guide rail 19 positioned on this side of the slider 4. In this example, the slider 4 has a clearance 49 of the upper side and the lower side of the slider 4.

This makes it possible to index the slider 4 laterally during assembly, the immobilizing wall 10 indexing it in depth. This also makes it possible to engage the left rails 19 more quickly with the left grooves 45 and the right rails 18 with the right grooves 44.

As here, the slider 4 may comprise a lug 48 arranged on the slider so as to abut in an orifice 15 of the immobilizing wall 10, when the slider 4 is in the first position Pi. This orifice 15 and this spigot 48 thus form a stop system to the fourth position P ₄ . This avoids driving the slide 4 to the mounting position when the slide is unlocked.

In this example, the same projecting element, here the rod 43 provides locking in one position and the immobilization in two other positions.
