Definitions

  • the invention relates to a control device comprising a facade with a front face bearing marks and / or symbols, and at least one operating member capable of being moved in front of said front face so as to bring an index that it includes opposite one or the other of said references and / or symbols, the marks and / or symbols and the index being suitable for being illuminated by a light source from the back of the facade, the operating member being formed of at least two subjects, namely a first subject translucent defining the index and a second opaque material covering the first material so as to conceal it from the viewed from the front, except for the index finger (this is usually known in the art).
  • the invention applies in particular, but not exclusively, to heating or air conditioning control panels the passenger compartment of motor vehicles.
  • front face to the user of the control device
  • front and rear refer to this convention. It is note that in the case of a heating control panel vehicle, the front panel is generally facing the rear of the vehicle.
  • Transparent materials such as polycarbonate and polymethyl methacrylate, and translucent materials such as polyamides and ABS (acrylonitrile-butadiene-styrene terpolymer), are commonly used as as light conductors in the control panels.
  • an operating member such as a rotary knob a matt appearance and a pleasant velvety touch by making it at least superficially in an elastomer suitable such as a mixture of polypropylene and a terpolymer ethylene-propylene-diene known under the name abbreviated EPDM.
  • EPDM terpolymer ethylene-propylene-diene
  • the invention provides that the first and second materials are respectively polypropylene and an elastomer with a mat appearance and a velvety feel.
  • the invention also relates to an operating member suitable for being part of a control device such as defined above, formed from at least two materials, namely a first translucent material defining an index and a second opaque material covering the first material of so as to conceal it from view in a specific direction, with the exception of the index, the first and second subjects being respectively polypropylene and an elastomer with a mat appearance and a velvety feel.
  • the control panel 1 includes a front panel 2 in the form of a substantially flat plate of which only part is represented.
  • a circular opening 3 is made in the facade 2, and a chimney 4 extends rearwards from from the edge of the opening to guide in rotation, around the axis A of the opening, the rod 5 of an operating button 6.
  • This rod 5 is connected, facing the front face 7 of the front, with a larger diameter operating head 8.
  • the rod 5 has a blind axial bore 9 of polygonal profile, open to the rear, suitable for receiving the end a tree not shown in conjugate profile belonging to a control mechanism intended, in the example illustrated, for adjust the position of one or more flaps in order to distribute a flow of treated air to different places in the passenger compartment of the vehicle, depending on the angular position button 6.
  • index 10 clearly visible from the front of the control panel, located near the periphery of the head and elongated radially.
  • Index 10 can be brought in, by manually rotating the knob, while look at different graphic symbols 11 which evoke different air distribution regimes.
  • Button 6 is made up of three different materials. he first includes a core of transparent material colored such as polycarbonate or polymethacrylate methyl, forming the rod 5 and a column 12 which extends towards the front from it, obliquely narrowing towards index 10. Column 12 is covered, radially on all sides and towards the front, by a body 13 in a second material which according to the invention is polypropylene translucent white, for example of the type marketed by TARGOR under the reference HOSTALEN PPW 1780S2AST. The part of the body 13 covering the end 14 of the column 12 has a reduced thickness and forms the index 10. Finally, a layer of mat black elastomer 15 covers the body 13, radially on all sides and forward, except index 10. In the example illustrated, the outer surface of layer 15 is flush with that of index 10.
  • the index 10 appears white on the black background of layer 15 when lit from the front of the control panel, especially by daylight. At night it is lit up, through the core 5, 12, by a light source arranged in back of facade 2, and appears with the color of the core, for example green or orange.
  • the button is advantageously produced by bi-injection molding on insert.
  • the body 13 is overmolded on the core 5, 12, previously molded and used as an insert, and layer 15 is overmolded on the body without removing the blank from the mold. We thus obtain a joining perfect polypropylene core and layer elastomer.
  • the operating member according to the invention can present any form other than that of a rotary button, especially that of a cursor or a push button.
