    Technical field to which the invention relates
    The present invention relates to electrical equipment.
    It relates more particularly to a control device comprising a housing containing at least one switch, and a control finger movable relative to the housing and having at least one element such as a rib projecting from one face of the control finger oriented towards The box.
    Technological background
    The document CN105336520 describes a control device of this type.
    In this document, the control finger has several ribs, some of which cooperate with elastic tabs of an intermediate piece mounted on the housing, while others cooperate directly with the switch.
    Object of the invention
    In this context, the present invention provides a control device as defined above, characterized in that the housing comprises a deformable region from which extend a first deformable tongue, arranged so as to cooperate with said element in at least one position of the control finger, and a second deformable tab for actuating the switch
    In such a device, the movement of the control finger (under the action of the user) causes the deformation of the first deformable tongue and consequently the deformation of the deformable region, which causes the deformation of the second deformable tongue of so as to operate the switch.
    The way in which these elements interact is however adjustable by the designer of the device, by playing in particular on the shape and the arrangement of the deformable region and of the deformable tongues, so that the designer can freely choose the feeling of the user when it moves the control finger for the switch actuator.
    The proposed design also makes it possible to avoid a direct action of an element such as a rib of the control finger on the switch and thus limits the risk of damage to the latter.
    Other non-limiting and advantageous characteristics of this control device are the following:
    - Said protruding element is a rib (or, alternatively, a pin, a pin or a cross);
    the control finger comprises another protruding element (for example another rib);
    - a third deformable tongue extends from the deformable region and in line with said other element (for example in line with said other rib);
    - The first deformable tongue and the third deformable tongue are located on either side of the second deformable tongue;
    - The control finger has a tab received in a recess of the housing and having a first contact surface oriented towards said face of the control finger;
    - The first deformable tongue is elastic and in contact with said element (in contact with said rib in the example described below) so as to press the first contact surface against a second contact surface formed on the housing and delimiting said recess ;
    - The deformable region, the first tab and the second tab are formed in a front wall of the housing;
    - The control finger has a wall extending over the periphery of the control finger surrounding said front wall;
    - the switch is carried by a printed circuit mounted in the housing;
    - the switch is a microswitch;
    - the second deformable tongue has a protrusion oriented towards the switch;
    - The deformable region is partially delimited by a plurality of cutouts;
    - said face of the control finger has an additional projecting element (such as an additional rib);
    - The housing comprises another deformable region from which extend a fourth deformable tongue, arranged so as to cooperate with the additional element (that is to say the additional rib in the example described), and a fifth deformable tab for actuating another switch (here another microswitch mounted on the printed circuit);
    - The housing includes at least one pin partially surrounded by a recess;
    - Said face of the control finger comprises a positioning rib received in said recess.

    FIG. 10 is a view of the detail D shown in FIG. 10.
    Figure 1 shows a control device according to the invention. As clearly visible in this figure, this control device comprises a cover plate 2, a control finger 4, an apparatus support 6 and an apparatus mechanism 8.
    In the present description, the terms "front" and "rear" will be used with respect to the direction of gaze of the user towards the wall on which the control device is attached. Thus, when the control device is installed in a room, the front will denote the side facing the inside of the room and the rear will denote the side facing away from the outside of the room.
    The apparatus support 6 has the form of a frame provided with a central opening 9 and allows the mounting of the control device in a housing (not shown), such as a mounting box intended to be positioned in a recess in the wall where the control device is to be installed. Alternatively, the housing can be surface mounted on the wall.
    To do this, the apparatus support 6 has orifices 10 in the form of a keyhole through which a fixing screw received elsewhere can extend in a barrel provided in the aforementioned case.
    As can be seen in FIG. 1, each orifice 10 comprises, on the one hand, an oblong part which receives the threaded barrel of the screw concerned (this oblong part extending along a rounding in order to allow angular catching up by sliding of the threaded barrel in this oblong rounded part), and, on the other hand, a circular end part authorizing the passage of the head of the screw concerned.
    The control device further comprises here a ring 5 mounted on the fitting mechanism 8 surrounding the control finger 4. This ring 5 has an external shape (here circular) complementary to a central opening 3 of the cover plate 2 and thus closes the space formed (here mainly laterally) between the control finger 4 and the internal edge of this central opening 3 (leaving a clearance allowing the movement of the control finger 4).
    As shown in FIGS. 2, 4, 7 and 9, the switchgear mechanism 8 comprises a box 12, 14 which contains electrical circuits 16, 18, here electronic circuits 16, 18.
    In the embodiment described, the housing consists of two assembled parts, namely a bottom part 12 and a cover 14 assembled by snap-fitting, here by the cooperation of elastic tabs 20 coming from the bottom part 12 with corresponding openings 22 formed in the cover 14.
    The two parts of the housing (that is to say the bottom part 12 and the cover 14) are here made of plastic.
    The aforementioned electronic circuits are made in the form of two printed circuits 16, 18, which each carry a set of electronic components.
    The housing 12, 14 of the fitting mechanism 8 comprises, here at the front wall 21 of the cover 14, a plurality of deformable tongues 24, 26, 28, 30, 32, 34, as described in more detail later. These deformable tabs 24, 26, 28, 30, 32, 34 are made of plastic as already indicated and thus have a certain elasticity.
    The printed circuit 16 closest to these deformable tongues 24, 26, 28, 30, 32, 34 (that is to say located towards the front) carries, on its face turned towards the deformable tongues 24, 26, 28, 30, 32, 34 (i.e. forward), a plurality of switches, here microswitches 36, 38, 40.
    At least one of these microswitches (here the microswitches 36, 38) is located at the right of a deformable tongue (here respectively the deformable tongues 26, 32) when the printed circuit 16 is mounted in the housing 12, 14.
    As can be seen in FIG. 2, the front wall 21 of the fitting mechanism 8 (here the front wall 21 of the cover 14) also defines a through opening 46 in line with a light source 40 (here produced in the form of a light-emitting diode 40 mounted on the printed circuit 16). As explained below with reference to FIG. 6, this through opening 46 is intended to allow a light guide 62 integral with the control finger 4 and whose front end is flush with the front face of the control finger 4 to pass through. so as to form a sight glass 7 (clearly visible in FIG. 1).
    The housing 12, 14 of the switchgear mechanism 8 (here precisely the cover 14) has a collar 42, formed around the entire periphery of the front wall 21 and recessed (backwards) relative to the front wall 21.
    As shown more particularly in Figures 1, 2 and 8, the housing 12, 14 of the fitting mechanism 8 (here precisely the cover 14) also comprises (at a side wall) a snap-in tongue (deformable ) 44 in order to retain the switchgear support 6 in contact with the flange 42: when mounting the switchgear mechanism 8 on the switchgear support 6 (through the central opening 9), the latching tongue 44 elastically disappears in order to allow the apparatus support 6 to come into contact with the collar 42, then returns to its rest position in order to retain the apparatus support 6 in contact with the collar 42 (see for example FIG. 8 ).
    As can be seen in FIGS. 2, 5, 8 and 10, the front wall 21 of the housing (here of the cover 14) carries on its front face at least one pin 48, here two such pins, for positioning the control finger 4. Each of these pins 48 is here disposed at an edge of the front wall 21 and is thus partially surrounded by a recess 50 intended to receive a complementary positioning rib 52 formed on the control finger 4.
    Indeed, as clearly visible in FIG. 6, the control finger 4 has on its rear face 55 (that is to say its face facing the switchgear mechanism 8 when the control device is assembled) in correspondence with the pins 48 two positioning ribs 52, produced here in the form of a C, so as to be received in the recesses 50 while partially surrounding the pins 48.
    The rear face 55 of the control finger 4 also includes ribs 54, 56, 58, 60 located respectively at the right (and here in contact) of corresponding deformable tongues 24, 28, 30, 34 when the control finger 4 is mounted on the fitting mechanism 8.
    As shown in Figures 2 and 6, the rear face 55 of the control finger 4 also has four other ribs 61 designed respectively to cooperate (at a side edge of the rib 61 concerned) with four corresponding surfaces 47 of the cover 14 (here four lateral surfaces perpendicular to the front wall 21 and extending from this front wall 21, as visible in FIG. 2) in order to guide the control finger 4 vertically (that is to say in a direction perpendicular to its pivot axis).
    Finally, as already indicated, a light guide 62, of axial extension greater than that of the ribs 54, 56, 58, 60 above, extends from the rear face 55 of the control finger in line with the opening through 46 so as to extend through it and to the right of the light source 40 when the control finger 4 is mounted on the fitting mechanism 8.
    A plurality of tabs 66 also extend at different points on the periphery of the control finger 4. Here, as clearly visible in FIG. 6, each edge (here of rounded shape) situated at one end of the control finger 4 (in the length of the control finger 4) has two tabs 66.
    The control finger 4, which is here of oblong shape, furthermore comprises a low wall 64 which extends backwards over the entire periphery of the control finger 4 so as to come and surround the front wall 21 of the housing of the mechanism apparatus 8 when the control finger 4 is mounted on the apparatus mechanism 8.
    The aforementioned tabs 66 extend here from the wall 64, at different points on the periphery of the control finger 4 as already indicated.
    The low wall 64 extends moreover rearwards at the level of these (rounded) end edges than in the other regions of the periphery of the control finger 4.
    As clearly visible in FIG. 5, when the control finger 4 is mounted on the casing of the fitting mechanism 8, each of the tabs 66 is received in a corresponding recess 68 formed in the casing of the fitting mechanism 8 (here in the cover 14) at the immediate rear of the front wall 21.
    Each of the tabs 66 has a surface 70 facing (/.e. Turned towards) the rear face 55 of the control finger 4 (the surface 70 therefore being oriented towards the front). When the control finger 4 is mounted on the fitting mechanism 8 and at rest, this surface 70 is in contact with a surface 72 delimiting the recess 68 and turned away from the control finger 4 (/.e backwards), as clearly visible in figure 5.
    In the example described here, when the control finger 4 is in the rest position (/.e. Is not requested by a user), each of the ribs 54, 56, 58, 60 is in contact with a tongue deformable 24, 28, 30, 34 corresponding, with a slight deformation (elastic) of these deformable tabs 24, 28, 30, 34 (towards the printed circuit 16, i.e. backwards), as well visible in FIG. 10 for the rib 54 and the deformable tongue 24.
    Thus, in the position mounted on the casing of the fitting mechanism 8, the control finger 4 is permanently urged forward (thanks to the elasticity of the deformable tongues 24, 28, 30, 34 which tend to return in their rest position, not deformed) so that the surface 70 of each tab 66 is held in contact with the corresponding surface 72 bordering the recess 68 formed in the housing of the fitting mechanism 8 (here in the cover 14).
    The control finger 4 is retained in this way on the housing 12, 14 of the fitting mechanism 8.
    The legs 66 (and the wall 64 which carries them) also have a certain elasticity in order to be able to move apart when the control finger 4 is mounted on the housing of the fitting mechanism 8.
    Each deformable tongue 26, 32 located in line with a microswitch 36, 38 here has a protrusion 74 in the direction of the microswitch 36, 38 concerned (/.e. Backwards) so that a part of the deformable tongue 26 , 32 (here the protrusion 74) is located in the immediate vicinity of the microswitch 36, 38 concerned when the control finger 4 is mounted on the switchgear 8 and is in the rest position (/.e. Not stressed by a user), as shown in Figure 8.
    As can be seen in FIG. 2, the front wall 21 of the cover 14 comprises a first deformable region 76 partially delimited by cutouts 82, 84, 86 so that this first deformable region 76 is only connected to the other regions of the front wall 21 by portions 80 of reduced size (forming hinges) and can thus be moved relative to the other parts of the housing 12, 14 of the fitting mechanism 8.
    The deformable tongues 24, 26, 28 (also formed in the front wall 21) extend from this deformable region 76.
    Specifically, the front wall 21 has a lateral (straight) cutout 84 which defines an edge of the deformable region 76 and an edge of the deformable tongue 24. The front wall 21 moreover has a transverse (straight) cutout 88 which opens into the lateral cutout 84 and which 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. The lateral cutout 84 and the transverse cutout 88 are here perpendicular.
    Still in FIG. 2, the deformable tongue 24 (located at the right, and here in contact, of the rib 54 of the control finger 4) and the deformable tongue 26 (located at the right of the microswitch 36) are separated by a first opening ( here rectilinear) 90 which opens 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. The first opening 90 is here perpendicular to the transverse cutout 88 (and therefore parallel at the side cutout 84).
    Similarly, the deformable tongue 26 (located at the right of the microswitch 36) and the deformable tongue 28 (located at the right, and here in contact, of the rib 56 of the control finger 4) are separated by a second opening (here rectilinear) 92. The second opening 92 thus defines an edge of the deformable tongue 26 and an edge of the deformable tongue 28. The first opening 92 is here perpendicular to the transverse cutout 88.
    The front wall 21 of the housing (here of the cover 14) here has another lateral (rectilinear) cutout 86 which defines another edge of the deformable region 76 and an edge of the deformable tongue 28. This other lateral cutout 86 opens into the cutout transverse 88.
    The front wall 21 finally has an insulated cutout 82 extending between the two portions 80 connecting the deformable region 76 to the rest of the front wall 21. This insulated cutout 82 facilitates the formation of a hinge at the portions 82 and thus the deformation of the deformable region 76.
    The aforementioned cutouts and openings thus make it possible to define in the front wall 21 of the housing:
    - a first deformable tongue 24;
    - a second deformable tongue 26;
    - a third deformable tongue 28.
    When a user exerts a force on the upper part of the control finger 4, the ribs 54, 56 of the control finger 4 move the corresponding deformable tongues 24, 28 backwards (i.e. towards the inside the housing, or towards the printed circuit 16), which results in the deformation of the deformable region 76 in the same direction and thereby the displacement of the deformable tongue 26 backwards, that is to say in contact with microswitch 36 (here by means of protuberance 74).
    When the movement thus generated by the user continues towards the rear, the deformable tongues 24, 28 deform until it causes (via the deformable region 76) a deformation of the deformable tongue 26 sufficient to actuate the microswitch 36.
    The use of a tongue 24, 28 (at least) deformed under the action of the control finger 4 and of a separate tongue 26 for actuating the switch (here the microswitch 36) makes it possible to define so flexible the relationship between the movement of the control finger 4 and the actuation of the switch 36, playing in particular on the shape of the deformable region 76 and deformable tongues 24, 26, 28.
    It is thus possible in particular to choose more freely the movement of the control finger 4 and the associated effort required to trigger the switch 36. Similarly, according to the movement of the tongue 26 obtained by a given movement of the control finger 4 , one can choose a sudden trip of the switch 36 or a more progressive trip of the latter.
    Thus, by playing on the shape of the deformable region 76 and the deformable tongues 24, 26, 28 (that is to say by playing on the shape of the cutouts 82, 84, 86, 88 and openings 90, 92 above-mentioned) , it is possible to modify the feeling of the user when he moves the control finger (in particular his tactile feeling, as well as possibly his auditory feeling, due for example to the sudden or progressive triggering of the switch 36) .
    The use of a tongue 24, 28 (at least) deformed under the action of the control finger 4 and of a separate tongue 26 for actuating the switch (here microswitch 36) also makes it possible to avoid that the force supplied by the user is not directly transmitted to the switch 36 and risks damaging the latter.
    The front wall 21 has another deformable region 94 from which extend the deformable tongues 30, 32, 34.
    As can be seen in FIG. 2, the deformable region 84 and the deformable tongues 30, 32, 34 are produced symmetrically from the deformable region 76 and the deformable tongues 24, 26, 28. We can therefore refer to the description above as regards the constitution and functioning of the deformable region 84 and the deformable tongues 30, 32, 34.
    The cuts and openings formed in the lower part of the front wall 21 thus make it possible to define:
    - a fourth deformable tongue 30;
    - a fifth deformable tongue 32;
    - a sixth deformable tongue 34.
    When a user exerts a force on the lower part of the control finger 4 (possibly simultaneously with a force on the upper part as described above), the ribs 58, 60 of the control finger 4 move the corresponding deformable tongues 30, 34 backwards (that is to say inside the housing, or again towards the printed circuit 16), which causes the deformation of the deformable region 94 in the same direction and thereby the displacement of the deformable tongue 32 towards the rear, that is to say in contact with microswitch 38.
    If the movement of the lower part of the control finger 4 continues rearward under the action of the user, the deformable tongues 30, 34 are deformed until causing (via the deformable region 94) a deformation of the deformable tongue 32 sufficient to actuate the microswitch 38.
    The user can thus control the actuation of the microswitch 36 or of the microswitch 38, or even of these two microswitches 36, 38, depending on the way in which he exerts a force on the control finger 4.
    In the above examples and as clearly visible in FIG. 2, two deformable tongues 24, 28 are used; 30, 34 each displaced by a rib 54, 56; 58, 60 of the control finger 4 and located on either side of the deformable tongue 26; 32 until actuating the switch 36; 38.
    This arrangement allows good control of the movement of the deformable tongue 26; 32 which operates the switch 36; 38. In particular, the deformable tongue 26; 32 is precisely deformed along the actuation axis of the switch 36; 38.
    It is however possible as a variant to provide a deformable region from which extends a single first deformable tongue in contact with the control finger and a second deformable tongue until the switch is actuated. Indeed, in this case also the deformation of the first tongue causes a deformation of the deformable region, which thus causes a deformation of the second deformable tongue in order to actuate the switch, as explained above.
    Furthermore, although in the example described here the switchgear mechanism 8 carries a single control finger 4, it can be envisaged as a variant that several control fingers 4 are provided in the front wall of the switchgear mechanism 8, the switchgear mechanism 8 then being shaped as described above (and shown in the figures) opposite each of the control fingers used.
