The casing (12, 14) comprises a deformable region (76) from which a first tab (24) extends, arranged so as to cooperate with said element in at least one position of the control finger, and a second tab (26) for actuating the switch (36).

Description

CONTROL DEVICEt

TECHNICAL FIELD TO WHICH THE INVENTION RELATES The present invention relates to electrical accessories. More particularly, it relates to a control device comprising: a casing that contains at least one switch; and a control member that is movable relative to the casing and that presents at least one element such as a tab that projects from a face of the control member, which face is oriented towards the casing.

TECHNOLOGICAL BACKGROUND Document CN 105336520 describes a control device of this type. In that document, the control member presents a plurality of tabs, some of which co-operate with resilient tongues of an intermediate part mounted on the casing, while others co-operate directly with the switch. Document DE 20 2004 005 837 discloses a switch including a toggle button and a casing that receives an electronic module. The face of the casing that is covered by the toggle button presents actuator elements that are W-shaped, having a central branch that includes both a bearing zone for receiving an element that projects from the toggle button, and an action zone that is situated above a switch element of the electronic module. It is to be understood that, any prior art publication referred to herein, does not constitute an admission that the publication forms a part of the common general knowledge in the art, in Australia or any other country. In the claims and in the description of the invention, except where the context requires otherwise due to express language or necessary implication, the

t Translation of the title as established ex officio.

18936662_1 (GHMatters) P45706AU00 word "comprise" or variations such as "comprises" or "comprising" is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.

SUMMARY OF THE INVENTION In accordance with the present invention, there is provided a control device comprising: a casing that contains at least one switch; and a control member that is movable relative to the casing and that presents at least one element that projects from a face of the control member, which face is oriented towards the casing; wherein the casing includes a deformable region from which a first tongue and a second tongue extend, wherein the first tongue is arranged so as to co-operate with said element in at least one position of the control member such that said element is configured to move the first tongue, thereby causing the deformable region to deform and the second tongue to move for actuating the switch. There is also described a control device which comprises: a casing that contains at least one switch; and a control member that is movable relative to the casing and that presents at least one element that projects from a face of the control member, which face is oriented towards the casing, wherein the casing includes a deformable region from which there extends a first tongue that is arranged so as to co-operate with said element in at least one position of the control member, and a second tongue (that is preferably movable at least in part)for actuating the switch. In such a device, movement of the control member (under the action of the user) causes the first tongue to

18936662_1 (GHMatters) P45706AU00 move and/or to deform, and consequently causes the deformable region to deform, which causes the second tongue to move and/or to deform so as to actuate the switch. However, since the second tongue is distinct from the first tongue, the way in which the elements interact can be adjusted to a considerable extent by the designer of the device, in particular by acting on the shape and on the arrangement of the deformable region and of the tongues, such that the designer can freely select the sensation perceived by the user when moving the control member so as to actuate the switch. The proposed design also makes it possible to avoid an element such as a tab of the control member acting directly on the switch, and thus limits the risks of damaging said switch. Other characteristics of the control device that are non-limiting and advantageous are as follows: • the first tongue and the second tongue extend parallel to each other and/or spaced apart from each other; • said projecting element is a tab (or in a variant a peg, a spike, or a spider); • the control member includes another projecting element (e.g. another tab); • an optionally deformable third tongue (distinct from the first tongue and from the second tongue) extends from the deformable region and in register with said other element (e.g. in register with said other tab); - the first tongue and the third tongue are situated on either side of the second tongue; • the first tongue and/or the second tongue are deformable (the second tongue thus possibly being deformable for actuating the switch); - the control member includes a catch that is received in a recess of the casing and that presents a

18936662_1 (GHMatters) P45706AU00 first contact surface that is oriented towards said face of the control member; - the first tongue is resilient and in contact with said element (in contact with said tab in the embodiment described below) so as to press the first contact surface against a second contact surface that is formed on the casing and that defines said recess; • the deformable region, the first tongue, and the second tongue are formed in a front wall of the casing; - the control member includes a rim that extends over the periphery of the control member, surrounding said front wall; • the switch is carried by a printed circuit that is mounted in the casing; the switch is a microswitch; • the second tongue presents a projection that is oriented towards the switch; • the deformable region is defined in part by a plurality of cutouts; - said face of the control member includes an additional projecting element (such as an additional tab); • the casing includes another deformable region from which there extend a fourth tongue that is arranged so as to co-operate with the additional element (i.e. the additional tab in the embodiment described), and a fifth tongue (movable at least in part) for actuating another switch (in this embodiment another microswitch that is mounted on the printed circuit); - the fourth tongue and/or the fifth tongue are deformable (the fifth tongue thus possibly being deformable for actuating the printed circuit); • the casing includes at least one peg that is surrounded in part by a recess; - said face of the control member includes a positioner tab that is received in said recess.

DETAILED DESCRIPTION OF EMBODIMENTS The following description of non-limiting examples given with reference to the accompanying drawings, makes it possible to understand what the invention consists of and how it can be reduced to practice. In the accompanying drawings: - Figure 1 is an exploded perspective view of a control device of the invention; - Figure 2 is an exploded perspective view of an accessory mechanism of the Figure 1 control device; - Figure 3 is a front view of the Figure 1 control device, without its face plate; - Figure 4 is section view of the Figure 1 control device on plane E-E shown in Figure 3; - Figure 5 is a view of a detail F shown in Figure 4; - Figure 6 is a rear view in perspective of the control member of the Figure 1 control device; - Figure 7 is section view of the Figure 1 control device on plane A-A shown in Figure 3; - Figure 8 is a view of a detail B shown in Figure 7; - Figure 9 is section view of the Figure 1 control device on plane C-C shown in Figure 3; and - Figure 10 is a view of a detail D shown in Figure 9. Figure 1 shows a control device of the invention. As can be seen clearly in this figure, the control device comprises a trim plate 2, a control member 4, an accessory support 6, and an accessory mechanism 8. In the present description, the terms "front" and "rear" are thus used relative to the direction in which the user looks at the wall on which the control device is fitted. Thus, when the control device is installed in a room, "front" means the face facing into the room, and "rear" means the face facing the opposite way, away from the room.

18936662_1 (GHMatters) P45706AU00

The accessory support 6 presents the form of a frame that is provided with a central opening 9 and that enables the control device to be mounted in a box (not shown), such as a flush-mounted box for positioning in a recess of the wall in which the control device is to be installed. In a variant, the box may be surface mounted on the wall. To do this, the accessory support 6 includes orifices 10 in the shape of keyholes suitable for receiving respective fastener screws that are also received in pillars provided in the above-mentioned box. As can be seen in Figure 1, each orifice 10 comprises firstly an oblong portion that receives the threaded shank of the screw in question (the oblong portion extending along a curve in order to enable angular compensation by sliding the threaded shank in the curved oblong portion), and secondly a circular end portion that makes it possible to pass the head of the screw in question. In this embodiment, the control device also includes a ring 5 that is mounted on the accessory mechanism 8, surrounding the control member 4. The ring 5 has an outer shape (in this embodiment a circular shape) that is complementary to a central opening 3 of the trim plate 2, and that thus comes to close (in this embodiment mainly laterally) the space formed between the control member 4 and the inner edge of the central opening 3 (leaving clearance that enables the control member 4 to move). As can be seen in Figures 2, 4, 7, and 9, the accessory mechanism 8 includes a casing 12, 14 that contains electrical circuits 16, 18, in this embodiment electronic circuits 16, 18. In the embodiment described, the casing is made up of two assembled-together portions, namely a base portion 12 and a cover 14 that are assembled-together by snap fastening, in this embodiment by co-operation between

18936662_1 (GHMatters) P45706AU00 resilient catches 20 coming from the base portion 12, and corresponding openings 22 formed in the cover 14. In this embodiment, the two portions of the casing (i.e. the base portion 12 and the cover 14) are made of plastics material. The above-mentioned electronic circuits are made in the form of two printed circuits 16, 18, each carrying electronic components. The casing 12, 14 of the accessory mechanism 8 includes a plurality of deformable tongues 24, 26, 28, 30, 32, 34, in this embodiment in the front wall 21 of the cover 14, as described in greater detail below. As mentioned above, the deformable tongues 24, 26, 28, 30, 32, 34 are made of plastics material and thus present a certain degree of springiness. The printed circuit 16 closer to the deformable tongues 24, 26, 28, 30, 32, 34 (i.e. situated towards the front) carries, on its face facing towards the deformable tongues 24, 26, 28, 30, 32, 34 (i.e. towards the front), a plurality of switches, in this embodiment microswitches 36, 38. At least one of the microswitches is situated in register with a deformable tongue when the printed circuit 16 is mounted in the casing 12, 14 (in this embodiment the microswitches 36, 38 are situated in register with the deformable tongues 26, 32 respectively). As can be seen in Figure 2, the front wall 21 of the accessory mechanism 8 (in this embodiment the front wall 21 of the cover 14) also defines a through opening 46 in register with a light source 40 (in this embodiment made in the form of a light-emitting diode 40 mounted on the printed circuit 16). As explained below with reference to Figure 6, the through opening 46 is for passing a light guide 62 that is secured to the control member 4 and that has a front end that is flush at the front face

18936662_1 (GHMatters) P45706AU00 of the control member 4 so as to form an indicator lamp 7 (as can be seen clearly in Figure 1). The casing 12, 14 of the accessory mechanism 8 (specifically the cover 14 in this embodiment) presents a collar 42 that is formed over the entire periphery of the front wall 21 and that is set back (towards the rear) relative to the front wall 21. As shown more particularly in Figures 1, 2, and 8, the casing 12, 14 of the accessory mechanism 8 (specifically the cover 14 in this embodiment) also includes (on a side wall) a (deformable) snap-fastener tongue 44 for holding the accessory support 6 in contact with the collar 42: while mounting the accessory mechanism 8 on the accessory support 6 (through the central opening 9), the snap-fastener tongue 44 deforms elastically so as to enable the accessory support 6 to come into contact with the collar 42, and then it returns to its rest position so as to hold the accessory support 6 in contact with the collar 42 (see Figure 8 for example). As can be seen in Figures 2, 5, 8, and 10, the front face of the front wall 21 of the casing (in this embodiment, of the cover 14) carries at least one peg 48, in this embodiment two such pegs, for positioning the control member 4. In this embodiment, each of the pegs 48 is arranged at an edge of the front wall 21 and is thus surrounded, in part, by a recess 50 for receiving a complementary positioner tab 52 that is formed on the control member 4. Specifically, and as can be seen clearly in Figure 6, on its rear face 55 (i.e. its face facing towards the accessory mechanism 8 when the control device is assembled together), the control member 4 presents, in correspondence with the pegs 48, two positioner tabs 52 that, in this embodiment, are C-shaped, so as to be received in the recesses 50, surrounding the pegs 48 in part.

18936662_1 (GHMatters) P45706AU00

The rear face 55 of the control member 4 also includes tabs 54, 56, 58, 60 that, when the control member 4 is mounted on the accessory mechanism 8, are situated in register with respective corresponding deformable tongues 24, 28, 30, 34 (and in this embodiment they are in contact with them). As can be seen in Figures 2 and 6, the rear face 55 of the control member 4 also presents four other tabs 61 that are designed to co-operate (at respective side edges of the tabs 61 in question) with four respective corresponding surfaces 47 of the cover 14 (in this embodiment four lateral surfaces that are perpendicular to the front wall 21 and that extend from the front wall 21, as can be seen in Figure 2) so as to guide the control member 4 vertically (i.e. along a direction that is perpendicular to its pivot axis). Finally, as mentioned above, a light guide 62, that extends axially farther than the above-mentioned tabs 54, 56, 58, 60, extends from the rear face 55 of the control member in register with the through opening 46, so as to extend through said through opening to face the light source 40 when the control member 4 is mounted on the accessory mechanism 8. A plurality of catches 66 also extend from various locations on the periphery of the control member 4. In this embodiment, and as can be seen clearly in Figure 6, each edge situated at a respective end of the control member 4 presents two catches 66 (in this embodiment the ends are in the long direction of the control member 4 and the edges are rounded in shape). The control member 4 is oblong in shape in this embodiment, and it also includes a rim 64 that extends rearwards over the entire periphery of the control member 4, so as to come to surround the front wall 21 of the casing of the accessory mechanism 8 when the control member 4 is mounted on the accessory mechanism 8.

18936662_1 (GHMatters) P45706AU00

In this embodiment, the above-mentioned catches 66 extend from the rim 64 at various locations on the periphery of the control member 4, as mentioned above. At the (rounded) end edges, the rim 64 also extends further towards the rear than it does in the other regions of the periphery of the control member 4. As can be seen clearly in Figure 5, when the control member 4 is mounted on the casing of the accessory mechanism 8, each of the catches 66 is received in a corresponding recess 68 that is formed in the casing (specifically in the cover 14) of the accessory mechanism 8, immediately behind the front wall 21. Each of the catches 66 presents a surface 70 that faces (i.e. that is turned towards) the rear face 55 of the control member 4 (the surface 70 thus facing towards the front). When the control member 4 is mounted on the accessory mechanism 8 and at rest, the surface 70 is in contact with a surface 72 that defines the recess 68 and that faces away from the control member 4 (i.e. that faces towards the rear), as can be seen clearly in Figure 5. In the embodiment described herein, when the control member 4 is in its rest position (i.e. not operated by a user), each of the tabs 54, 56, 58, 60 is in contact with a corresponding deformable tongue 24, 28, 30, 34, with the deformable tongues 24, 28, 30, 34 deforming elastically a little (towards the printed circuit 16, i.e. towards the rear), as can be seen clearly in Figure 10 for the tab 54 and the deformable tongue 24. Thus, in its position mounted on the casing of the accessory mechanism 8, the control member 4 is urged continuously towards the front (by means of the springiness of the deformable tongues 24, 28, 30, 34 that tend to return into their non-deformed rest position), such that the surface 70 of each catch 66 is kept in contact with the corresponding surface 72 that borders

18936662_1 (GHMatters) P45706AU00 the recess 68 formed in the casing of the accessory mechanism 8 (in this embodiment in the cover 14). As a result, the control member 4 is held on the casing 12, 14 of the accessory mechanism 8. The catches 66 (and the rim 64 that carries them) also have a certain degree of springiness, so as to be capable of moving apart while the control member 4 is being mounted on the casing of the accessory mechanism 8. In this embodiment, each deformable tongue 26, 32 situated in register with a microswitch 36, 38 includes a projection 74 that projects towards the corresponding microswitch 36, 38 (i.e. towards the rear), such that a portion of the deformable tongue 26, 32 (in this embodiment the projection 74) is situated in the immediate proximity of the corresponding microswitch 36, 38 when the control member 4 is mounted on the accessory mechanism 8 and is in its rest position (i.e. not operated by a user), as shown in Figure 8. As can be seen in Figure 2, the front wall 21 of the cover 14 includes a first deformable region 76 that is defined, in part, by cutouts 82, 84, 86, such that the first deformable region 76 is connected to the other regions of the front wall 21 only via portions 80 of small size (forming hinges), and can thus be moved relative to the other portions of the casing 12, 14 of the accessory mechanism 8. The deformable tongues 24, 26, 28 (also formed in the front wall 21) extend from the deformable region 76. Specifically, the front wall 21 presents a (rectilinear) side cutout 84 that defines an edge of the deformable region 76 and an edge of the deformable tongue 24. The front wall 21 also presents a (rectilinear) transverse cutout 88 that opens out into the side cutout 84 and that defines the free end edge of the deformable tongue 24, the free end edge of the deformable tongue 26, and the free end edge of the deformable tongue 28. In

18936662_1 (GHMatters) P45706AU00 this embodiment, the side cutout 84 and the transverse cutout 88 are perpendicular to each other. Still in Figure 2, the deformable tongue 24 (situated in register with, and in this embodiment in contact with, the tab 54 of the control member 4) and the deformable tongue 26 (situated in register with the microswitch 36) are separated by a first opening 90 (in this embodiment a rectilinear opening) that opens out into the transverse cutout 88. The first opening 90 thus defines an edge of the deformable tongue 24 and an edge of the deformable tongue 26. In this embodiment, the first opening 90 is perpendicular to the transverse cutout 88 (and thus parallel to the side cutout 84). Similarly, the deformable tongue 26 (situated in register with the microswitch 36) and the deformable tongue 28 (situated in register with, and in this embodiment in contact with, the tab 56 of the control member 4) are separated by a second opening 92 (in this embodiment a rectilinear opening). The second opening 92 thus defines an edge of the deformable tongue 26 and an edge of the deformable tongue 28. In this embodiment, the first opening 92 is perpendicular to the transverse cutout 88. In this embodiment, the front wall 21 of the casing (in this embodiment of the cover 14) presents another (rectilinear) side cutout 86 that defines another edge of the deformable region 76 and an edge of the deformable tongue 28. This other side cutout 86 opens out into the transverse cutout 88. Finally, the front wall 21 presents an isolated cutout 82 that extends between the two portions 80 that connect the deformable region 76 to the remainder of the front wall 21. The isolated cutout 82 facilitates forming a hinge at the portions 82, and thus facilitates deforming the deformable region 76. The above-mentioned cutouts and openings thus make it possible to define in the front wall 21 of the casing:

18936662_1 (GHMatters) P45706AU00

- a first deformable tongue 24; • a second deformable tongue 26; and - a third deformable tongue 28. The first, second, and third deformable tongues 24, 26, 28, taken in pairs, thus extend in parallel, and spaced apart from each other. Specifically, if, for each deformable tongue 24, 26, 28, a middle axis (or extension axis) is defined that extends between a zone where that deformable tongue 24, 26, 28 is connected to the deformable region 76 and the free end edge of that deformable tongue 24, 26, 28, then the deformable tongues 24, 26, 28, taken in pairs, present middle axes that are parallel and spaced apart from each other. When a user exerts a force on the top portion of the control member 4, the tabs 54, 56 of the control member 4 move the corresponding deformable tongues 24, 28 rearwards (i.e. towards the inside of the casing, or towards the printed circuit 16), which causes the deformable region 76 to deform in the same direction and likewise causes the deformable tongue 26 to move rearwards, i.e. in contact with the microswitch 36 (in this embodiment by means of the projection 74). When the rearward movement generated in this way by the user continues, the deformable tongues 24, 28 deform until the deformable tongue 26 has deformed enough (via the deformable region 76) to actuate the microswitch 36. The use of (at least) one tongue 24, 28 that is deformed under the action of the control member 4 together with the use of a distinct tongue 26 for actuating the switch (in this embodiment the microswitch 36) provides flexibility in defining the relationship between the movement of the control member 4 and the actuation of the switch 36, in particular by acting on the shapes of the deformable region 76 and of the deformable tongues 24, 26, 28.

18936662_1 (GHMatters) P45706AU00

In particular, there is thus greater freedom in selecting the movement of the control member 4 and the associated force necessary for triggering the switch 36. Likewise, depending on the movement of the tongue 26 obtained by a given movement of the control member 4, it is possible to select for triggering of the switch 36 to be sudden, or for triggering of the switch to be more progressive. Thus, by acting on the shapes of the deformable region 76 and of the deformable tongues 24, 26, 28 (i.e. by acting on the shapes of the above-mentioned cutouts 82, 84, 86, 88 and openings 90, 92), and in particular on the distances between the middle axes of two adjacent deformable tongues 24, 26, 28, it is possible to modify the sensation perceived by the user when moving the control member (in particular the tactile sensation, and possibly also the aural sensation, e.g. as a result of the sudden or progressive triggering of the switch 36). The use of (at least) one tongue 24, 28 that is deformed under the action of the control member 4 together with the use of a distinct tongue 26 for actuating the switch (in this embodiment the microswitch 36) also makes it possible to avoid the force delivered by the user being transmitted directly to the switch 36, which could risk said switch being damaged. The use of (at least) one tongue 24, 28 that is deformed under the action of the control member 4 together with the use of a distinct tongue 26 for actuating the switch (in this embodiment the microswitch 36) also makes it possible to define the sensation perceived by the user among a wide range of possibilities, in particular by varying the points of contact along the middle axes of the tabs 24, 28 between the tabs 54, 56 and the associated tongues 24, 28 and/or the point on the tongue 26 that actuates the switch 36 (via the projection 74).

18936662_1 (GHMatters) P45706AU00

The front wall 21 presents another deformable region 94 from which the deformable tongues 30, 32, 34 extend. As can be seen in Figure 2, the deformable region 84 and the deformable tongues 30, 32, 34 are arranged symmetrically to the deformable region 76 and the deformable tongues 24, 26, 28. As a result, reference can be made to the above description with regard to the constitution and the operation of the deformable region 84 and of the deformable tongues 30, 32, 34. The cutouts and openings formed in the bottom portion of the front wall 21 thus make it possible to define: • a fourth deformable tongue 30; • a fifth deformable tongue 32; and a sixth deformable tongue 34. The fourth, fifth, and sixth deformable tongues 30, 32, 34, taken in pairs, thus extend in parallel, and spaced apart from each other. Specifically, if, for each deformable tongue 30, 32, 34, a middle axis (or extension axis) is defined that extends between a zone where that deformable tongue 30, 32, 34 is connected to the deformable region 94 and the free end edge of that deformable tongue 30, 32, 34, then the deformable tongues 30, 32, 34, taken in pairs, present middle axes that are parallel and spaced apart from each other. When a user exerts a force on the bottom portion of the control member 4 (possibly simultaneously to a force on the top portion as described above), the tabs 58, 60 of the control member 4 move the corresponding deformable tongues 30, 34 rearwards (i.e. towards the inside of the casing, or towards the printed circuit 16), which causes the deformable region 94 to deform in the same direction and likewise causes the deformable tongue 32 to move rearwards, i.e. in contact with the microswitch 38. If the rearward movement of the bottom portion of the control member 4 continues under the action of the

18936662_1 (GHMatters) P45706AU00 user, the deformable tongues 30, 34 deform until the deformable tongue 32 has deformed enough (via the deformable region 94) to actuate the microswitch 38. The user can thus actuate the microswitch 36 or the microswitch 38, or both of the microswitches 36, 38, as a function of the way in which force is exerted on the control member 4. In the above-mentioned examples, and as can be seen clearly in Figure 2, two deformable tongues 24, 28; 30, 34 are used, each situated on either side of the deformable tongue 26; 32 and moved by a tab 54, 56; 58, 60 of the control member 4 until the switch 36; 38 is actuated. This arrangement provides good control over the movement of the deformable tongues 26; 32 that actuate the switches 36; 38. In particular, each deformable tongue 26; 32 is deformed accurately along the actuation axis of the corresponding switch 36; 38. However, in a variant, it could be envisaged to provide a deformable region from which there extend only one first deformable tongue that is in contact with the control member, and one second deformable tongue that deforms until the switch is actuated. Specifically, in this configuration likewise, deformation of the first tongue causes the deformable region to deform, which thus causes the second deformable tongue to deform so as to actuate the switch, as explained above. In addition, although in the embodiment described herein, the accessory mechanism 8 carries a single control member 4, a variant could be envisaged in which a plurality of control members 4 are provided in the front wall of the accessory mechanism 8, the accessory mechanism 8 thus having the above-described shape (as shown in the figures) facing each of the control members that are used.
