Definitions

  • the present invention relates to a transmission device between an operating button and a driven member.
  • driving shafts or pinions for example, they are found on board vehicles in control of radio or air conditioning equipment such as ventilation flaps.
  • the button can be extended by a solid or annular drive shaft.
  • the button can also be extended, still in one piece, by a sleeve or rod fitted on or threaded in a rod or sleeve integral with the member and linked together by a screw.
  • the operating button is in direct connection with the driven member. If the button is subjected to an axial or torsional stress, the stress is passed on to the driven member, which risks damaging it or altering its operation. To avoid this, the button is placed in a support and guide housing. However, an assembly of this type requires good precision and is therefore expensive.
  • buttons comprising means for exerting friction between the transmission device and a fixed part, by exerting a friction force in a displacement plane under the action of a restoring force substantially orthogonal to the displacement plane.
  • friction is poorly defined, since the friction means can alternatively adhere temporarily to the drive means and to the fixed part and create jolts detrimental to the feeling of comfort.
  • the present invention aims to overcome this drawback.
  • a transmission device between a driving operating button and a driven member, comprising means integral in driving the button and arranged to drive the driven member and to be driven by the button against the action of 'A friction force exerted by friction means and developed in a displacement plane under the action of a restoring force substantially orthogonal to said displacement plane, characterized in that the friction means are integral with the means of drive and intended to generate said friction force under the effect of the restoring force.
  • the restoring force can be applied by a spring, which allows, by the choice of its elasticity, to adjust its value.
  • the spring compensates for the dispersions of dimensions, but by engaging only a very small part of its available force, it applies, in its friction function, a substantially constant restoring force.
  • a magnet could have a similar effect.
  • said drive means comprise means of coupling in translation along the axis of the button intended to cooperate with means of coupling of the button and comprise a rotary shaft intended to drive the driven member and provided with coupling means in rotation intended to cooperate with coupling means of the button.
  • the drive means of the driven member are integral in displacement with a friction lining in support, under the action of a spring fixed to the drive means , against a wall of a button receiving housing.
  • the transmission device between an operating button 1 and a driven member 2 comprises a shaft 3, of axis 4, integral in rotation with the button 1 and the member 2 by its ends 5 and 6, respectively.
  • the end 5 is tubular and rotatably mounted in a bearing 12 formed by an extension of a chassis 10.
  • the chassis 10 carries the front face 50 of the dashboard in a housing 56 from which the button 1 is rotatably mounted.
  • the tubular end 5 of the shaft 3 is extended by a radial shoulder 6, 7 facing a flat surface 14 of the chassis 10, parallel, at a short distance, the shoulder 7.
  • a spring 20, here with a blade has a washer-shaped support portion 22 pierced with the internal diameter of the bearing 12 and of external diameter substantially equal to that of the shoulder 7.
  • the spring 20 is threaded on the end 5 of the shaft 3 and is supported, by its washer 22, on the shoulder 7.
  • the washer 22 is fixed to the shoulder 7 by conventional means not shown.
  • the washer 22 is extended, on the outside, by two opposite flexible arms 24 and 25.
  • Each arm 24, 25 comprises, at its free external end, a pellet 26, 27 of rounded shape projecting axially towards the surface 14 of the chassis 10.
  • the axial extension of the pads 26 and 27 is greater than the distance separating the shoulder 7 from the surface 14, so that the spring 20 is supported on one and the other and exerts, its two arms 24 and 25 being under stress, a restoring force tending to move the shaft 3 axially from the surface 14.
  • the shoulder 6 of the shaft 3, close to the button 1, is extended at the end, by a tubular skirt 8 coaxial with the axis 4 and terminated by a radial bearing surface 9.
  • the skirt 8 is covered with a O-ring 40, here made of elastic polymer material forced into the interior of the skirt 8, against which it is locked by friction. Ribs can be provided on the skirt and notches for receiving these ribs on the lining, to ensure additional locking in rotation between the shaft 3 and the lining 40.
  • the front face of the dashboard 50 comprises, facing the chassis 10, a friction surface 52 or strip 52 extending in a radial plane 60, on which the lining 40 is supported, under the action of the spring 20, and kept at a constant distance from the surface 14 of the chassis 10.
  • the button 1 comprises a tubular part 62 forming a foot, rotatably mounted in a bearing 54, also of axis 4, constituted by an extension of the front face 50 of the dashboard.
  • Button 1 has a shaped head 64 cup, centered on the tubular part 62, projecting out of the dashboard and extended by an annular skirt 66 with an axis 4.
  • the skirt 66 is disposed in a housing 56 of the front face 50 and the bottom of which prevents depression excessive button 1.
  • the end of the tubular part of the button 1 opposite the cup 64 extends slightly beyond the front face 50.
  • the tubular skirt 62 of the button 1 has five axial end tabs 70, 71, 72, 73 and 74 , with radial elasticity, ( Figure 2).
  • Each tongue 70 - 74 has, on its face opposite the axis 4 and near its free end, a groove of rounded shape, respectively 75, 76, 77, 78 and 79, receiving a bead 44 of the O-ring 40.
  • a key 82 (FIG. 2) integral with the skirt 8 of the shaft 3 is radially housed in a slot 84 of the foot 62 of the button 1, ensuring a rotational coupling between the button 1 and the shaft 3.
  • the shaft 3 comprises, at its end close to the member 2, a toothed crown 86 engaged with a toothed crown 88 of the driven member 2.
  • the shaft 3 being pushed axially by the spring 20 in the direction of the friction surface 52, the lining 40 is pinched between the latter and the skirt 8.
  • the distance between the surface 14 and the shoulder 7 is such that the axial deformation arms 24, 25 of the spring 20 is significantly greater than the uncertainties in the distance between the surface 14 and the friction surface 52 as well as the uncertainties on the axial dimensions of the parts, which ensures a substantially constant restoring force.
  • the skirt 66 of the button comes, by its edge, into contact with the bottom of the housing 56, which prevents excessive axial movement of the button 1 and of the shaft 3 and prevents modification significant of the restoring force.
  • the button 1 If the user pulls the button 1 axially, it is retained by the bead 44 of the lining 40 cooperating with the grooves 75 to 79 of the tabs 70 to 74. It is however possible to change the button 1 by pulling axially strongly on the head 64, which, due to the rounded shape of the grooves 75 to 79, separates from the axis 4 the part 44 of the lining 40, housed in the grooves 75 to 79 and, in the opposite direction, causes the tongues 70 to 74 to flex radially towards the axis 4.
  • the guiding in rotation of the button 1 is ensured by the tongues 70 to 74 and the bearing 54, the edges of the housing 56 only serving to avoid an overhang of the button 1 which, in the event of a radial impact on its head 64, would risk uncoupling from the lining 40 by damaging the bearing 54.
  • the button 1 is, here, integral with the shaft 3 by means of the lining 40.
  • the ends of the elastic tongues 70 to 74 of the button 1 and the internal face opposite the skirt 8 of the shaft 3 may respectively have a protuberance and a corresponding housing ensuring a direct connection in translation as well as in rotation between the button 1 and the shaft 3, which ensures better guidance in rotation of the button 1.
  • the presence of the lining 40 is only useful insofar as the materials of the bearing surface 9 and of the dashboard 50 do not have the qualities desired to ensure smooth sliding.
  • the spring 20 can be left free in rotation and translation or that it can, for example, be locked in rotation relative to the shoulder 7 and be sliding on the surface 14, or vice versa.
  • the spring 20 then plays at least partially the role of the lining 40 and it can, if necessary, wear friction means cooperating with the surface 14.
  • the bearings must then be in the form of a light following the desired path in the direction of movement and carry a connecting rod replacing the shaft 3, while the different contact surfaces extend parallel to the parallel edges of the lights.
  • the friction surface 52 is then formed of two parallel friction bands, while the pads 26 and 27 of the spring 20 slide on two parallel sliding bands.
  • the packing can keep a toric shape in order to always press on the two friction bands whatever its angular position around the axis.
  • the connection angle between each friction strip and the associated lumen is then rounded to avoid "injuring", during a rotation of the button 1, the unsupported part of the lining 40 in line with the lumen and which "rises”"on a rub.
  • the two support pads 26 and 27 of the spring 20 are, for example, guided in grooves of the surface 14 extending along the direction of movement of the button 1, the spring 20 being free to rotate relative to the shaft 3, or they can also, for example, be replaced by an O-ring arranged radially to the shaft 3, the spring 20 then being able to rotate without risk of getting caught in bearing 12.
