- the control panels comprise a plate, at least one control member, or button, rotatably mounted on the plate about an axis and comprising a toothed ring provided with notches, and an indexing member carried by the plate. and arranged to cooperate with the notches.
- Control boards of this type which comprise at least one control member which can be brought into any one of a plurality of selected angular positions, or indexed positions, in which the indexing member comes, each time, cooperate with a notch of the notched crown. This makes it possible to define a succession of different positions which each correspond to a particular setting value of the equipment which is controlled by the array.
- Such a control panel is, for example, taught by the French patent application FR2872744-A1.
- control boards find application in many areas, such as radio, navigation, telephony, and so on.
- These tables can be used in particular in the automotive field to control equipment, including a heater, ventilation and / or air conditioning of the passenger compartment of a motor vehicle.
- control panel may comprise, for example, a button for controlling the temperature of the passenger compartment, a button for adjusting the air flow and a button for adjusting the distribution of the distribution of the air flow. traveling in the cockpit. If the temperature of the passenger compartment can be adjusted according to different zones, the number of buttons can be increased to ensure independent adjustment of air flows distributed in different areas.
- indexing member in the form of a leaf spring, also called “notching blade”, cooperating with the notches of the toothed ring to define a number of indexed positions or number of clicks. It is also known to perform the indexing by a ball biased by a spring acting on the notches of the notched crown.
- the known indexing members create radial and axial parasitic forces on the notched crown. These forces cause an imbalance of the notched ring generating friction that can affect the rotation of the control member. This creates spurious handling efforts that do not promote a pleasant feeling for the end user who must manipulate the control elements of a control panel as described in the preamble.
- the known devices often require straight and elongate notching blades and having bulky attachment means. They therefore require space for their installation and also for assembly. In addition, the receiver board must be engineered accordingly.
- the indexing devices must meet the requirements of cost and haptic feeling. Indeed, they must be made on the one hand inexpensively and inexpensively and on the other hand have a "noble” or “soft” notch as is known, for example known HIFI chain control buttons, particularly with control buttons having a large diameter.
- the object of the present invention is in particular to overcome the aforementioned drawbacks.
- the invention proposes an indexing member comprising a support having a contour and at least two indexes arranged on the support, characterized in that the indexes are evenly distributed over the contour of the support, characterized in that the indexes are disposed on respective deformable members, having a free end.

- FIG. 1 shows a control panel, generally designated by the reference 10, and comprising a plate 12, of generally flat shape on which are mounted, in the example, three rotary knobs.
- a first button 14 is disposed in a central region of the plate.
- a second button 16 and third button 18 are located on either side of the button 14. These buttons are arranged to be rotated manually by a user, in one direction or in the other, around respective axes of rotation which extend perpendicularly to the general plane of the plate.
- the plate 12 of the control panel is substantially flat and the axis of rotation of the button extends perpendicularly to this plane. Nevertheless, different geometrical conformations could be envisaged for which the present invention is also applicable.
- this control panel is intended to be mounted on the dashboard of a motor vehicle to control various parameters associated with a piece of equipment of this vehicle, in particular a heating, ventilation and / or air conditioning system. of the passenger compartment of a vehicle.
- buttons 14, 16 and 18 can be used, for example, to adjust the temperature, the air flow rate and the distribution distribution of an air flow in a passenger compartment of a motor vehicle.
- buttons 16 and 18 are made in a similar manner to the latter.
- the button 14 comprises a body 20, which may, according to an alternative embodiment, be striated to facilitate its grip by the user.
- This body 20 is extended by a stop ring 22 cooperating with the surface of a facade (not shown) to axially maintain the button 14.
- a toothed crown 24 and a ring gear 26 defining a plurality of axial teeth 28 are respectively arranged one after the other.
- the button 14 is hollow and is intended to engage around a cylindrical shaft 30 from the plate 12 extending along an axis XX '.
- the button 14 is rotatably mounted about the axis XX 'of the cylindrical shaft 30.
- This is referred to as a button with an axis 30 of large diameter (that is to say that the diameter of the shaft is in the same orders of magnitude or more large than the height of the drum) and hollow which allows on the one hand to obtain a better strength and on the other hand the insertion of central buttons for example of the type of support ("push" in English).
- the teeth 28 of the button 14 come to interface with walls 32 arranged on the plate 12 and housing an encoding device (for example an optical encoder).
- the encoding device is disposed on an electronic circuit (not shown) arranged behind the plate 12 to provide an encoding function.
- the encoding function is provided by an optical encoder.
- openings are made in the walls 32 to let light beams that interrupted by the teeth 28 of the button 14 when the latter is rotated.
- the button 14 can be held in a selected angular position by cooperation of an indexing device consisting of an indexing member 100 and the notches 25 of the notched crown 24.
- the indexing member 100 will be detailed more precisely in relation to Figures 2 to 4.
- the notches may be in the form of waves, bumps or notches.
- FIG. 2 is a sectional view from above of the indexing member 100 according to a first embodiment as arranged in the control panel 10 of FIG. 1.
- the indexing member 100 comprises a support arranged in the form of a frame 104 having an outer contour 110 and an inner contour 106. According to the present embodiment, the frame 104 is closed and defines an opening 108 for the passage However, according to an alternative covered by the present invention, the frame 104 may be partially open.
- the frame 104 is in the form of a parallelogram, in particular a square.
- the inner contour 106 has indexes 102 cooperating with the notches 25 of the toothed crown 24.
- the indexes are in the form of internal free-end partitions 124 and are four in number.
- the indexes can take other forms of realization and be in number greater than four. At a minimum, the indexes are two in number, symmetrically distributed.
- the indexes 102 are equi-distributed on the inner contour 104. Indeed, the defined angle whose vertex is on the axis XX 'and between two successive indexes 102 is 90 ° .
- the equi-distribution of the indexes 102 is defined by a uniform arrangement of the indexes 102 on the inner contour 104.
- the angle between two successive indexes is identical regardless of the pair of successive indexes chosen.
- the angle between two successive indexes is 360 / N.
- Such an arrangement allows to have a balance of forces exerted by the indexes 102 on the notched crown 24 during handling thereof.
- the vector sum of the forces is zero and the centroid of the indexing member is on the axis XX 'of rotation of the notched crown 24.
- the number of notches 25 of the toothed ring 24 is defined so that in all indexing positions, the indexes 102 are arranged in a notch 25.
- the notched crown 24 has thirty-two notches 25.
- the number of screens is a multiple of the number of indexes.
- the shape and dimension of the indexes are adapted to obtain the greatest possible compactness.
- the size of the indexes can be chosen small enough to interfere and penetrate the shape and geometry of the notches.
- the indexes 102 are arranged on respective deformable members.
- the deformable members are formed by the deformable areas. More precisely, the deformable zones are obtained from the formation of an inner wall portion 124 having a deformable free end formed in the frame 104 of the indexing member 100.
- This partition portion 124 is delimited between the inner contour 106 of the indexing member 100 and a groove 126 made through the frame 104 in the vicinity of its outer contour 110. The presence of this groove 126 allows a crushing of the internal partition portion 124 when the index 102 disposed on the latter passes on the top separating two notches 25 successive.
- the groove 126 is made through the frame 104 of the indexing member 100 to provide a release of material that can be occupied by the internal partition 124 when it is deformed.
- the frame 104 comprises a plurality of deformable zones 120 which are formed on its periphery, being arranged substantially centrally with respect to the indexes 102.
- the grooves 126 formed in the frame 104 of the indexing member 100 are holes or stampings. They thus define the portions of internal partitions 124 deformable between the inner contour 106 and the groove 126 and outer walls 122 disposed between the groove 126 and the outer contour 110.
- the indexes 102 follow the curvature of the notches 25 of the notched crown 24. Thus, they come into contact with the apex separating two successive notches 25 compressing the deformable zone 120 to mark the passage from one position to another.
- the elasticity of the deformable zone 120 ensures an action tending to bring the indexes 102 into the hollow of a notch 25. It thus prevents the unstable position of an index 102 on the top separating two successive notches 25.
- holes 112 are arranged in a distributed manner on the frame 104 to allow the passage of fastening means, such as screws, rivets or clips.
- the frame 104 has a circular shape. Such an arrangement makes it possible to ensure a reduced bulk of the indexing member 100. Indeed, the circular shape of the frame 104 makes it possible to minimize the space of the opening 108 which is not occupied by the notched crown 24, symbolized in dashed line in Figure 3.
- indexes 120 are homogeneously distributed over the inner contour 106 of the frame 104 of the indexing member 100.
- the indexes 120 according to the arrangement of FIG. are separated from each other by 120 ° .
- the indexes 102 of the inner contour 106 cooperate with the notches 25 of the toothed crown 24 and are arranged on respective deformable members 120 made by arms 130.
- the arms 130 are made in the form of a deformable internal partition formed in the frame 104 of the indexing member 100 at the inner contour 106. More particularly, each arm 130 has a fixed end attached to the frame 104 and a free end of any connection with the frame 104. This free end carries the index 102
- the arm 130 is detached from the frame 104 by a gap 132 between the arm 130 and the frame section 104 defining the outer contour 110.
- the geometric disposition of the arm 130 allows an elastic displacement of its free end. Consequently, the index 102 can move so as to allow the passage from one position to another without creating parasitic forces.
- the indexes 102 follow the curvature of the notches 25 of the notched crown 24. Thus, they come into contact with the apex separating two notches 25. successively compressing the arm 130 to mark the passage from one position to another. Moreover, the elasticity of the arm 130 prevents the unstable position of an index 102 on the vertex separating two successive notches 25 during the rotation of the button 14.
- the embodiment of Figure 4 is a variant of the arrangement of the indexing member of Figure 3 comprising four indexes 102 distributed on the inner contour 106 of the frame 104 of the indexing member 100.
- the arms 140 constitute the respective deformable members 120. They are similar to the arms 130 described in relation with FIG.
- the arms 140 are connected in pairs to the frame 104 of the indexing member 100 via the junction 146.
- the junctions 146 attach the fixed ends of each arm to the frame 104 of the indexing member 100.
- gaps 142 Between either side of the junctions 146 are arranged gaps 142 between the arms 140 and the frame section 104 defining the outer contour 110. These gaps 146 allow the arms 140 to be detached from the frame 104.
- the arms 140 have an elastic deformation of their free ends so that the indexes 102 can move to allow the passage from one position to another without create parasitic forces.
- the arrangement of the arms 130 and 140 as described in relation with FIGS. 3 and 4 allows a symmetry of the friction forces. These friction forces are arranged in pairs and thus cancel the possible dissymmetry maneuver in a first direction of rotation, for example the clockwise, and in a second direction of rotation, for example counterclockwise.
- an arm disengages one notch while another arm engages in a notch.
- the indexes 102 follow the curvature of the notches 25 of the notched crown 24. Thus, they come into contact with the apex separating two successive notches 25 compressing the arms 140 to mark the transition from one position to another. Moreover, the elasticity of the arms 140 prevents the unstable position of an index finger 102 on the vertex separating two successive notches 25 during the rotation of the button 14.
- the shape of the indexes may be asymmetrical.
- the positioning and the holding in position of the indexing member 100 on the plate 12 of the control panel 10 are carried out by fixing means, as screws or rivets, arranged through holes 148 arranged in a distributed manner on the frame 104.
- buttons 16 and 18 of Figure 1 are similarly made and therefore will not be described in detail.
- the notched crown is susceptible of many embodiments. Preferably, it comprises a succession of recesses in an arc defining the notches.
- An alternative embodiment of the notched crown consists of a succession of bosses in the form of an arc disposed on its periphery and which turn their concavity towards the center of the notched crown, that is to say on the side of its rotation axis. These bosses thus define two by two a series of notches each formed at the junction of two consecutive bosses.
- notches can be made on all or only a part of the toothed crown and that the angular intervals defined by these notches can be equal or different, depending on the chosen applications.
- the shape of the bosses or hollows is likely to many variants, depending on the degree of firmness that will feel the user when operating the button in rotation. It may be in particular forms of the type tip, flat, etc., or a combination of such forms.
- the present invention also covers the indexing members comprising a support having an outer contour and at least two indexes arranged on the outer contour of the support in an equi-distributed manner.
- This exemplary embodiment covers in particular the devices in which the indexes, such as the arms or the walls, are carried by the rotary knob 14.
- the indexes 102 are arranged in place of the notched crown 24.
- the notches 25 are arranged on a dedicated zone of the plate 12.
- the indexing member is made of a different material than that used for the manufacture of the button, in particular the member 100 is made of polycetal (POM PolyOxyMethylene) which is a soft material and sliding which limits friction and improve wear resistance.
- polycetal POM PolyOxyMethylene
- this member 100 in a thin sheet, folded and stamped spring (for example bronze, stainless steel or steel) or with a lubrication, or by producing the free ends of the deformable members (120) which are in contact with the notching with plastic or PTF inserts.
- the present invention finds a particular application in the control panels integrated with equipment of many technical fields, and in particular in the field of motor vehicle equipment, in particular heating, ventilation and / or air conditioning installations.
- the indexing member and the control panel equipped with such an indexing member can be applied to all types of installation having a control panel comprising control members or buttons manipulated by the user in order to set various parameters of the installation.
