DEVICE FOR IMMOBILIZING A CARTRIDGE IN A CASE, CASE COMPRISING SAID DEVICE AND ASSEMBLY OF SAID CASE AND SAID CARTRIDGE.

FR 3 063 681 - A1 ftv) The invention relates to a device for immobilizing a cartridge (130) in a housing (100), said device comprising a trigger (400), allowing in a first position, the maintenance of said cartridge (130) in said housing (100), and in a second position, the introduction / extraction of said cartridge (130) relative to said housing (100), said device further comprising a locking member (500) of said trigger , said locking member (500) being configured to come into a locking position of said trigger (400) in said first position, said trigger (400) and said locking member (500) being movable in two different directions.

The invention also relates to a housing comprising a housing, intended to receive said cartridge (130), and such an immobilization device as well as an assembly of said housing and said cartridge. Application to diffusion devices, in particular fragrance devices, in particular for motor vehicles.

The present invention relates to a device for immobilizing a cartridge in a housing, a housing comprising said device and the assembly of said housing and said cartridge. It will find its applications, in particular, in a diffusion device forming part of a motor vehicle.

There are known devices comprising a housing accommodating a removable cartridge, said housing being provided with a button making it possible to extract the cartridge from the housing when it is actuated.

This is the case with the fragrance diffusion devices found in certain motor vehicles. Volatile agents are housed in the cartridge which must be changed when the volatile agents are used up. The button on the housing is accessible to the passenger. It allows the removal of the cartridge. However, before the delivery of the motor vehicle, in particular during its transport to the dealer, the removable cartridge is already placed in the diffusion device.

Before the delivery of the vehicle, it can be tempting for any individual to take this removable cartridge which is an expensive element of the vehicle.

In order to avoid possible theft, it is thus advantageous to have a system for blocking said removable cartridge which does not allow its removal from the housing.

There is therefore a need to have an effective locking system before the delivery of the vehicle.

It has already been developed in this sense by the applicant for mechanisms operating with a stop provided on one of the organs of the diffusion device. These mechanisms have the advantage of not requiring additional parts since they call on one of the component organs of the device. However, it may be necessary to strengthen the robustness of the locking system.

The invention aims to improve this aspect of robustness and proposes for this purpose a device for immobilizing a cartridge in a housing, said device comprising a trigger, allowing in a first position, the maintenance of said cartridge in said housing, and in a second position, the introduction / extraction of said cartridge relative to said housing, said device further comprising a locking member of said trigger, said locking member being configured to come into a locking position of said trigger in said first position, said trigger and said locking member being movable in two different directions.

Thanks to the invention, the locking member and the trigger being movable in two different directions, a force exerted on the trigger during an attempt at forced withdrawal has little or no effect on the locking member. It therefore becomes very difficult, if not impossible, to force the trigger when it is blocked by the locking member. In addition, even if successful, the risk of another mobile device being damaged is minimal. The device thus remains functional, only the disappearance of the cartridge being deplored. We have a kind of reliable solution allowing the delivery of a box pre-equipped with a cartridge and ready to use.

According to additional characteristics of the invention which can be taken together or separately:

- said locking member is configured to bear on a wall of the housing in the event of actuation of the trigger in said locking position,

said locking member is configured to position itself between said trigger and said housing wall in the locked position,

said locking member is movable in translation,

- said trigger is movable in translation,

a direction of movement of said locking member and a direction of movement of said trigger are orthogonal,

said locking member comprises a return spring configured to keep said locking member away from said locking position when said cartridge is in use,

said locking member comprises a fork intended to cooperate with said trigger in the locked position,

said trigger comprises a return spring in said first position,

said trigger comprises a cartridge blocking bar,

- Said fork and said bar are configured to abut one against the other in said blocking position.

According to an advantageous embodiment of the invention, said device comprises a movable member, called a selector, configured to occupy different positions relative to the cartridge. Preferably, said locking member is then configured to be actuated by said selector to come into said blocking position of said trigger in said first position. Thus, according to this aspect of the invention, the locking member can be simply released, for example when the vehicle is sold. In addition, the advantage of a locking member is retained, the activation / deactivation of which is determined by one of the constituent members of the device, namely the selector, while enhancing its reliability through the use of the member. lock mentioned above. Said selector is, for example, movable in rotation. Said locking member is, in particular, movable tangentially to said selector,

The invention also relates to a housing comprising a housing, intended to receive said cartridge, and an immobilization device as described above.

According to additional characteristics of the invention which can be taken together or separately:

said housing comprises a side forming a facade,

- said trigger is movable along said facade,

- said return spring of the locking member bears against an internal face of said facade,

- Said trigger can be actuated in translation in a direction transverse to a direction of introduction / extraction of the cartridge.

The invention also relates to an assembly formed by the housing mentioned above and said removable cartridge.

According to different embodiments of the invention which can be taken together or separately:

- the removable cartridge is provided with at least one cavity,

the cartridge comprises a plurality of openings, in particular in communication with the said cavity or cavities,

said cavities house at least one volatile agent,

- the volatile agents include odorous beads.

The invention also relates to a diffusion device comprising an assembly as described above.

According to different embodiments of the invention which can be taken together or separately:

- said selector is configured to leave open at least one of the openings of the cartridge,

- Said selector comprises at least one inlet and one outlet for an air flow, said diffusion device being configured to put said inlet and said outlet in communication, with at least one of said cavities so that the latter is crossed by said air flow.

The invention will be better understood in the light of the following description which is given for information only and which is not intended to limit it, accompanied by the accompanying drawings among which:

- Figure 9 reproduces Figure 8, the locking member being in a position where it blocks the trigger.

As illustrated in the figures, the invention relates to a device for immobilizing a removable cartridge in a housing, in particular for a diffusion device allowing the treatment of an air flow using volatile agents, including fragrances.

According to an advantageous embodiment of said device, the volatile agents, in particular the fragrances, comprise a substrate, in particular beads, loaded with volatile compound (s). It could in particular be odorous beads.

In Figure 1, the diffusion device or diffuser is illustrated as a whole. It includes here a housing 100 on which two orifices serve as inlet 105 and outlet 110 for air. Therefore, the housing serves as an air guide and includes a plurality of components which will allow air to circulate in the housing. Preferably, an interface on the orifices 105, 110 allows a tube, not shown, to be fixed there while ensuring the airtightness of the system.

The diffuser comprises a cartridge 130 of fragrances and a selector, here housed in said housing 100. The selector comprises, for example, an input selector 125a, an output selector 125b and a movable axis 135 driving them. Said diffuser further comprises here an actuation mechanism 150, allowing a drive of said axis 135.

The housing 100 can be fixed at different locations on the vehicle, preferably on the dashboard or in the glove compartment so that the latter is easily accessible to the passenger. Indeed, the cartridge is removable relative to said housing and it is advantageous that the passenger can easily change the cartridge.

The air outlet of the housing 110 is connected, for example, to a grid through which the treated or scented air leaves. This grid can be fixed at different locations in the vehicle. Preferably, it is located on the dashboard or near the ventilation systems of the windshield, the grid being connected to the outlet of the housing by the tube already mentioned.

Here, the housing 100 comprises a base 180, for example a rectangular parallelepiped. In the base are housed a pulser 115 located above the inlet 105 of the housing and at least part of the actuation mechanism 150. Said actuation mechanism may include a motor 140. The latter is fixed to the housing 100 au- above the blower 115, and is outside the housing. Above the base 180, and next to the motor 140, a second part of the housing 170 has a substantially cubic shape for housing the fragrance selector and the cartridge 130. These parts of the housing are assembled one to the other. other. Air tightness is ensured throughout the housing. The inlet 105 is in the base 180 of the housing 100, on the underside and below the blower 115. The outlet 110 is on the upper side of the second part 170, above the selector exit 125b.

The air enters the housing through the inlet port 105, being sucked in by the blower 115. This blower generates the air flow which will finally exit the housing through the outlet port 110 after passing through the cartridge. 130. The air flow is illustrated by line 120 in FIG. 1. Preferably, the blower 115 is of the radial type, but it can also be of the axial type.

The cartridge 130 is advantageously composed of a plurality of cavities in which different fragrances can be accommodated. The selector 125a, 125b is configured so that one or more of these cavities are crossed by the air flow so that it is charged with volatile compounds of the selected fragrance (s). In other words, when the air flow crosses said selected cavity or cavities, the air comes into contact with the entire substrate contained in each of said cavities and said substrate releases the compound or compounds which will perfume and / or treat the flow air, and then the passenger compartment of the motor vehicle.

For this, the air flow 120 enters the cartridge 130 through an input of the input selector. The air flow then passes through the cartridge 130 from one side to the other, passing through one or more of the cavities of said cartridge, which it leaves through an outlet of said outlet selector 125b. By passing through the cavity or cavities selected by the air flow, it ensures an optimized loading of the air flow by the fragrance, the latter coming into contact with the entire surface of the associated substrate. After being removed from the cartridge, the air flow is here guided to the outlet port 110 of the housing.

Preferably, the blower 115 allows the device to be independent of the ventilation, air conditioning or heating system with which the vehicle is possibly equipped. It can therefore be used independently of these systems, which makes it all the more flexible in use. In another embodiment, it is connected to the ventilation, air conditioning or heating system of the vehicle. The inlet 105 and outlet 110 ports would in this embodiment be connected to a conduit of said system.

Figure 2 provides a more detailed view of Figure 1 without the housing 100. Figure 2 illustrates the details of the actuating mechanism 150, the movable shaft 135 and the input selector 125a and output 125b. The cartridge 130 is illustrated in more detail in FIG. 3.

The actuation mechanism 150 comprises for example the motor 140, a shaft 220, a transmission pinion 230, advantageously allowing a gear reduction, and a straight pinion 240. The motor 140 drives the kinematics of the elements located downstream: the shaft 220 , directly connected to an engine actuator, drives the transmission pinion 230, which drives the spur gear 240. The movable pin 135 is directly fixed on the spur gear 240 and is therefore also driven by the latter.

Advantageously, the input selector 125a and the output selector 125b are in the form of turntables, the movable axis 135 piercing the two turntables in their center. The shape of the hole piercing the turntables corresponds to the shape of a section of the movable axis, preferably square in shape so that when the movable axis rotates, the turntables also rotate. The turntables are separated by a distance corresponding to the height of the cartridge 130 in order to allow the cartridge to be inserted therein. When the cartridge is inserted between the two plates, the latter are advantageously pressed against the cartridge by springs, not shown, in order to ensure airtightness.

Preferably, the inlet and outlet of the air flow on the turntables situated respectively upstream and downstream of the cartridge are in the form of through openings 260b (the opening 260a upstream of the cartridge does not is not visible) whose size is comparable to that of an inlet, respectively an air outlet, of a cavity of the cartridge. The openings of the two turntables are arranged opposite so as to ensure the continuity of the air flow. On the other hand, the positions of the openings of said turntables remain synchronized during their movement thanks to the movable axis 135 which connects them.

Figure 3 provides a view of the insulated cartridge 130. As already said, the cartridge 130 is a removable element relative to the housing 100. The passenger of the vehicle can then easily change the cartridge, especially when it is empty, the duration of cartridge life is approximately 3 months for normal use. By "vacuum" is meant whose fragrances are exhausted and no longer release volatile compounds.

The cartridge is here provided with an introduction front 310 in said housing, which is similar to the front of a drawer. Said facade 310 is here provided with housings 312 (FIG. 5) facilitating the insertion of said cartridge 130 into the housing 100. The cartridge 130 is also provided with a longitudinal guide rib 315 situated along the three vertical faces which go 'insert into the housing 100. To accommodate said guide ribs 315 of the cartridge 130, the housing also has guide grooves 160, illustrated in FIG. 1, on either side of the cartridge housing in the housing and above the lower turntable 125a.

A slot 320 allows the passage of the axis when the cartridge is inserted into the housing between the two turntables 125a and 125b illustrated in Figures 1 and 2. In the position of use, the movable axis 135 is located in the center of the cartridge in the bottom of the slot.

The cartridge comprises a body 360 and a cover 350 whose shape is parallelepiped and the base is substantially square. The body is compartmentalized to define said cavities, the bottom of said body comprises the air flow inlets of said cavities, and the cover comprises the air flow outlets of said cavities. The cartridge is preferably made of plastic. Said openings may be coated with a mesh or a porous film to retain the substrate of said fragrances while letting the air flow pass through.

Advantageously, cavities occupied by a fragrance and empty cavities alternate. The alternation of empty cavities and cavities housing a fragrance makes it possible to pass from each of the cavities comprising a fragrance to a cavity not comprising one, without passing through a cavity comprising another fragrance.

In an embodiment as illustrated in FIG. 3, the different cavities of the cartridge and their respective openings form angular portions of a ring. In this particularly advantageous embodiment, five cavities are provided, three of which to house a fragrance 340a, 340c, 340e and two are intentionally left empty 340b, 340d. The angle swept by the openings of each angular portion is in this embodiment slightly less than 60 degrees. In such an embodiment, the openings 260a, 260b of the plates are also in the form of an angular portion, each plate here comprising a single opening 260a, respectively 260b.

The passenger can therefore choose between three different fragrances according to their tastes: different atmospheres are possible during the trip, which can be particularly pleasant for long trips. These different fragrances can also be very useful for masking or filtering an undesirable smell of tobacco, for example. The passenger can also choose to leave the ventilation system running without being in the presence of a fragrance.

Such a distribution of the cavities, in the form of angular ring portions, makes it possible to easily increase the number of cavities without having to modify the associated actuation mechanism. The only change to increase the number of fragrances available to the passenger resides in the size of the cavities of the cartridge and in the size of the openings of the turntables which correspond to them.

FIGS. 4a to 4b illustrate a top view of the mechanism allowing the change of fragrances carried out by the assembly comprising the cartridge 130 and the selector 125a, 125b. The figure shows only the turntable 125b located on the cartridge 130. However, the bottom view would be represented in the same way. The movable axis 135 as well as the slot 320 of the cartridge 130 are also visible in the figure.

In the embodiment described in FIG. 3, where the cartridge comprises five cavities, three of which are dedicated to accommodating a fragrance and two are left empty, FIGS. 4a to 4e illustrate the passage of the opening 260b of the turntable 125b on each of the five positions. Figure 4a illustrates the first position of the turntable where the fragrance released comes from the cavity 340a of Figure 3. To move to the second position, illustrated in Figure 4b, the turntable will rotate counterclockwise a angle of about 60 degrees. This position corresponds to an empty cavity of the cartridge corresponding to the cavity 340b of FIG. 3. FIG. 4c illustrates the effect of an additional rotation in the counterclockwise direction of approximately 60 degrees relative to the second position allowing to release the second fragrance housed in the cavity 340c. Similarly, Figures 4d and 4e illustrate the opening of the turntable located respectively on the cavities 340d for the fourth position and 340e for the fifth position of the cartridge.

Preferably, to move to a later position, the turntable will rotate clockwise. Indeed, there is an area through which the turntable does not pass during its use. This area is located above the slot 320, or between the cavities 340a and 340e. The usefulness of such an area will be better understood below.

The alternation of empty cavities and cavities housing a fragrance allows the passenger to adjust the intensity of the fragrance diffused by actuating the selector back and forth. For the same purpose, it is also possible to place the opening of the turntable in an intermediate position between the empty cavity and the filled cavity. When the opening completely covers the opening of the cavity, then the diffusion is complete, when the opening covers only part of the opening of the cavity comprising the volatile agent, then the diffusion is only partial.

A device control system may include a programming module and associated electronics to allow the passenger to control the blower and the motor of the electrical actuation mechanism. Preferably, the passenger can control the fragrance dispenser from a steering wheel control.

The control system allows the driver to turn on the fragrance dispenser, to choose the intensity of the fragrance diffused, to choose the flow rate of the diffused air flow and / or to choose the fragrance. Advantageously, the control system indicates when a fragrance of the cartridge is empty.

As illustrated in FIGS. 5 to 6, the device for immobilizing the cartridge 130 comprises a trigger 400, allowing, in a first position, the maintenance of said cartridge in said housing, and in a second position, the introduction / extraction of said cartridge 130 with respect to said housing 100. In FIG. 6, the trigger 400 is in its first position.

Said trigger 400 can here be actuated in translation in a direction, illustrated by an arrow marked 412 in FIG. 6, transverse, in particular orthogonal, to a direction of insertion / extraction of the cartridge, illustrated by an arrow marked 414 in FIG. 6 (as in Figure 1). Such an orientation makes it possible to have a simple and robust trigger.

Said trigger 400 comprises, for example, a bar 420 for blocking the cartridge 130 and a tongue 422 for actuating the bar 420. Said tongue 422 here projects perpendicularly to the bar with which it is optionally made of material.

The housing 100 includes a front face 424, provided with an orifice 426 for inserting / removing the cartridge 130. Said front face 424 is also provided with a notch 428 for passage of the tongue 422, allowing the user to manipulate the latter from the outside, in a movement oriented in direction 412. Said notch 428 can be formed in the contour of the orifice 426 for inserting / extracting the cartridge 130 or, as here, being independent. With a frame 425 of the device, said front face 424 of the housing forms a front for receiving the cartridge 130.

Said tongue 422 can be configured to come opposite two opposite longitudinal edges of said notch 428, with a slight play, so that said tongue 422 is guided along said longitudinal edges of the notch, thus facilitating guiding the bar 420 in its translational movement.

Said strip 420 comprises, for example, at least one stop 430, here two stops 430, for blocking the cartridge 130. In the example, said stops 430 are located at a contour of said strip 420, in particular along from one of its edges 432, said to be lower, at the level of two opposite longitudinal ends of said strip 420.

For its part, said cartridge comprises at least one blocking pin 434, here two blocking pins 434, each intended to cooperate with one of said stops 430. In the example, said bar 420 is movable in translation along a face 450 of the cartridge, called the upper face, namely the face of the cartridge at the level of which said upper rotary plate 125b moves. Said blocking pins 434 are also located at the level of said upper face 450, at the level of the tops of the cartridge so as to be outside the space requirement of said upper turntable 125b, when the cartridge is in position.

Preferably, said blocking pins 434 are slightly set back from a rear face of the facade 310 of the cartridge 130 so that said bar 420 is guided in its translational movement between said pegs 434 and said facade 310 of the cartridge 130.

The said blocking pin or pins 434 are advantageously provided with a cutaway, intended to cause actuation in translation of the bar 420 during the introduction of the cartridge 130.

As illustrated in FIG. 7, said trigger 400 may also include a return element, such as a spring 438, capable of holding the bar 420 in said first position in the absence of actuation of trigger 400, that is to say say, as long as the tongue 422 is not moved by a user wishing to remove the cartridge 130. Said spring 438 bears on the housing 100, here on a side face 502 of said housing, and on said strip 420, for example by by means of a plate 440 provided with a guide finger 442 of the spring 438. Said plate 440 may come from said bar 420. Said guide finger 442 is advantageously oriented in the direction of translation 412 of the bar 420.

In FIG. 7, it can be seen that said housing 100 may also include one or more pads 452 for guiding the bar 420, here coming from the upper face of said housing. Said bar 420 is located between said guide pads 452 and said front face of the housing 100.

Still in FIG. 7, it can be seen that said notches 430 are distant from one another along said strip 420. An intermediate notch 460 is here provided along said lower edge 432 of the strip, between said notches 430 cooperating with stops 434.

As illustrated in FIGS. 8 and 9, according to the invention, said immobilization device further comprises a locking member 500 of said trigger 400. Said locking member 500 is configured to come into a locking position of said trigger 400 in said first position, that is to say in the position in which the cartridge 130 is held in the housing by said trigger 400. Said trigger 400 and said locking member 500 are movable in two different directions. In this way, during a fraudulent attempt to withdraw the cartridge 130, while said locking member 500 is in the locked position, the force exerted on the trigger 400 does not or little refers to the locking member 500 since the latter is not movable in the same direction. The risk of successfully forcing trigger 400 is therefore reduced.

Advantageously, said locking member 500 is configured to bear on a wall of the housing 100, here on the same side wall 502 on which the trigger return spring 400 is supported, in the event of actuation of the trigger 400 in said position. blocking. For this, here, said locking member 500 is configured to be positioned between said trigger 400 and said side wall 502 of the housing, in the locked position. Said locking member 500 is thus sandwiched during an attempt to fraudulently withdraw the cartridge 130, which further reinforces the reliability of the blocking of the cartridge.

Said locking member 500 is, for example, movable in translation. As already mentioned, said trigger 400 is also, for example, movable in translation. Preferably, a direction of movement of said locking member 500 and a direction of movement of said trigger 400 are orthogonal. They correspond here, respectively, to directions 412 and 414, previously mentioned. The transfer of force from one to the other is therefore minimum, or even zero, in particular in the event of the locking member 500 pressing on the housing 100, except when working material deformation, which would require a particularly important effort.

Said locking member comprises a return spring 504, configured to keep said locking member 500 away from said locking position when said cartridge 130 is in use.

Said locking member 500 comprises, for example, an elongated body 506. Said body 506 has a first end 508 coming between said trigger 400 and said side wall 502 of the housing, in the locked position. Said body 506 of the locking member 500 is provided with a shoulder 510, said return spring 504 bearing, at one of its ends, against said shoulder 510.

As mentioned above, said housing 100 comprises a front face 424, forming a front of the housing, here orthogonal to the lateral face 502 against which bears said trigger return spring 400. Said return spring 504 of the locking member is supported at the other of its ends, against an internal wall of said front face 424.

Advantageously, said locking member 500 is configured to be actuated by one of said selectors, here the output selector 125b, to come into said blocking position of said trigger 400 in said first position. As already mentioned above, said selector 125b is here mobile in rotation. Said locking member 500 is, for example movable tangentially to said selector 125b.

Said selector 125b here comprises a stop 512 for driving said locking member 500 by said selector 125b. To simplify the reading of the figures, only the stop 512 has been illustrated in Figures 8 and 9, without the rest of the selector 125b. If one refers to FIGS. 4a to 4e, it can be seen that the angular travel of the stop 512 is limited, taking into account the zone in which the opening 260 b of said selector does not pass, which makes it possible to avoid conflicts with surrounding organs.

Said stop 512 of the selector 125b acts, for example, on one end 514 of the body 506 of the locking member, opposite the end 508 used for blocking the trigger 400. Said stop 512 is formed, in particular, of a pin projecting from the disc defining said selector 125b, in the direction of the axis of rotation 135 of said selector 125b.

Said end 508 serving for locking the trigger is, for example, in the form of a fork, intended to cooperate with said trigger 400 in the locked position. Teeth of said fork are configured to pass on either side of return spring 438 of trigger 400. Said fork and said bar 420, in particular a longitudinal end of said bar 420, are configured to come into abutment one against the other in said blocking position. More specifically, in the locked position, the teeth of said fork are sandwiched in their thickness between a face of said strip 420, forming a longitudinal end edge of said strip 420, and said side wall 502 of the housing. .

In FIG. 7, said stop 514 of selector 125b is at a distance from 5 the locking member 500 and the trigger is free to pass from the first to the second position and vice versa. The return spring 504 of the locking member 500 is not constrained.

In FIG. 8, the selector has been rotated and the stop 514 of the selector 125b has pushed the locking member into the blocking position. Its end 508 is thus between the trigger 400 and the side wall 502 of the housing. The return spring 504 is constrained so that as soon as the stop 514 of the selector 125b changes position, the locking member leaves the locking position.

Although the immobilization device according to the invention has been described in the context of a device for diffusing several fragrances, it can also be used with cartridges serving only for one fragrance. It can also be used with cartridges used for another application than a diffusion device.
