Definitions

  • the present invention relates to a mechanical arrangement for adjusting an adjustable unit, and more particularly to a mechanical arrangement for setting an adjustable unit with an integrated light display.
  • Such arrangements such as for adjusting electrical components such as vehicle exterior mirrors or for opening and closing an electrical contact from a remote location (eg, the driver's seat of the vehicle) are known in the art.
  • a remote location e.g, the driver's seat of the vehicle
  • Such arrangements include a shaft which transmits a force exerted by an operator at a remote location, for example, to an actuator for a vehicle outside mirror moving engine. The engine converts this force again into a corresponding exterior mirror setting.
  • some known solutions provide illumination of the operating element. For example, proves to be advantageous for reasons of space illumination of the control element from the inside out.
  • a shaft end integrally connected to the operating knob actuates an electromechanical switching unit in the switch interior.
  • the control knob receives a light-conducting element which is illuminated laterally by a light source arranged in the interior of the switch. This serves to backlight the control knob.
  • the US 4,778,966 shows a pressure switch with a longitudinally reciprocally movable, non-rotatable actuating pin which receives a light-conducting element.
  • the light-conducting element is illuminated, for example, in the dark and leads the light out to the operator end of the actuating pin.
  • the US 2006/0102456 A1 relates to a reciprocable switch with a shaft for actuating the electromechanical switching unit. From a light source arranged inside the switch, light is led out through a light-conducting element, which is arranged in the shaft, to the switch.
  • the US 6,565,223 B2 shows the features of the preamble of claim 1. It describes a rotary knob, for example for setting a potentiometer.
  • a special lighting device illuminates the knob in the dark from the inside.
  • the rotation axis of the rotary knob used for transmitting a movement of the rotary knob, for example on the potentiometer may be made of a transparent material and thus support the continuous illumination of the control knob.
  • the GB 2 417 138 A shows a switch for operating the exterior mirrors of a vehicle.
  • the switch comprises a control knob which is connected to a base via an axis of rotation, on which a light source is arranged. For the direction of the light from the light source to the control knob provides a disposed inside the axis of rotation light-conducting element.
  • the invention addresses the problem of providing an easily manufactured and assembled arrangement for setting an adjustable unit with integrated light display.
  • the invention solves this problem by an arrangement, a use or a method according to the independent claims.
  • the dependent claims relate to advantageous embodiments of the invention.
  • Adjustable units include electronic and electromechanical units.
  • these are electrical components integrated into any desired electrical circuits, for example, rotary capacitors for setting radio frequencies or resistors or potentiometers for controlling a motor.
  • An adjustment of such units by an operator for example, in adaptation to the current application, prevailing environmental conditions or at his discretion.
  • the arrangement according to the invention is used to set adjustable units which - for example due to their function-related arrangement, for safety reasons or to protect the units from environmental influences such as dust and water - are not directly accessible and / or without aids.
  • sensitive electrical components such as adjustable electrical resistors or potentiometers, are typically in a protective housing.
  • the invention uses a shaft.
  • the shaft transmits a rotational and / or pulling / pushing movement exerted by the operator on the unit, which in turn converts this movement into a corresponding setting.
  • a rotary shaft transmits a torque to a rotary potentiometer and thus twists its electrical sliding contact.
  • the invention provides according to an embodiment, a light indicator of the unit state.
  • a light indicator of the unit state may be provided.
  • these may be units which are arranged in the vicinity of the unit to be set, for example other elements of the circuit, which also include the adjustable unit, or electrical components, for example motors, arranged in the same housing.
  • the light of the illuminated display comes from one or more light sources arranged at the adjustable unit, for example from one or more LEDs.
  • the light sources are able to detect and display the state of the adjustable unit or other units arranged in this area without much effort. Wiring and soldering costs are thus greatly reduced.
  • the "state of a unit” is, for example, the current value or state of the variable to be set or another variable dependent on the quantity to be set or independent. Frequently, the "state of a unit” is also calculated from any measured value, or it results after coding.
  • a flashing LED may represent exceeding a threshold of a variable relating to the adjustable and / or another unit; a binary coded display in which each LED represents one bit, the current resistance (or resistance ratio) of a potentiometer; or an indication of changing color, the adjustment margin up to a point of maximum displacement of, for example, an adjustable capacitor.
  • the detection of the state of the unit works: for example, a switching logic or the like preceding the light sources is considered. suitable Metrics signals or sizes, or the light source is integrated into an existing circuit of adjustable or another unit, indicating the existing current flow or its strength directly.
  • the invention uses as wave a light guide, for example one or more commercially available glass fibers or polymeric optical fibers.
  • a light guide for example one or more commercially available glass fibers or polymeric optical fibers.
  • Such photoconductive fibers have a core and a cladding having a lower optical index than the core; the refractive index transition occurs either abruptly or gradually from the inside to the outside.
  • Light coupled into the fiber is reflected at the boundary layer between the cladding and the core and thus guided in the core.
  • the light of several light sources can be transmitted for a more complex light signal representation (number representations or the like).
  • the positioning of the light sources in the adjustable unit is carried out so that their light is possible without any intermediate elements directly coupled into the optical waveguide used as a wave.
  • the invention also includes embodiments in which an "indirect" coupling via intermediate elements, such as mirrors, takes place.
  • a light guide according to the invention as a wave represents a favorable solution, which determines the number of necessary arrangement components as well as the space required for the arrangement reduced.
  • the invention has a particularly favorable effect, for example, when used in a closed housing, since, in addition to the passage opening for the shaft, no additional passage openings in the housing have to be provided for the illuminated display.
  • Difficulties may arise in some applications due to the relatively low mechanical strength of most optical fibers: ultimately, the optical fiber alone transfers the force that the operator uses to adjust to the unit to be adjusted.
  • optical fibers usually have only a small torsional stiffness. Such problems may occur, for example, when the operator attempts to twist an item to be adjusted beyond its inherent stop. Then the force exerted by the operator will cause the fiber to twist, which in turn may lead to its destruction. Therefore, some embodiments of an inventive arrangement an over-rotation, which corresponds for example to the end of the adjustment of the element to be adjusted. Also for the protection of - partly also mechanically little claimable - to be adjusted such an over-rotation often proves to be advantageous.
  • Securing the so-called self-supporting light guide and the adjustable unit against acting on the shaft train or pressure includes, for example, an arrangement of the shaft with play in its axial longitudinal direction. Of course, this will only work to a limited extent if a compressive force transmitted via the shaft is to be used to set the unit.
  • the light guide can be used as protection against strong pressure forces about to be provided with a control with a stop, for example, a simple pressure switch with two positions.
  • an operating element is arranged to provide the operator with an ergonomic gripping surface.
  • the operating member often gives the operator the manner of the adjustment to be made by providing, for example, a knob to be made by rotating a knob, a pressure switch to be made by pressure, etc.
  • the indicator is normally located at the operator's facing side of the control element, which is designed for this purpose, for example, partially transparent or has a through hole through which the shaft passes.
  • a control element with through opening can fulfill a certain protective function where it encloses the light guide.
  • the control element is cylindrical with an operating end, an inner end and a coaxial through hole formed thereto and is arranged with its operator outside and its inner end within a housing, so that the operating element encloses the extending through its through hole light guide at the point of passage into the housing , As a result, friction forces acting on the edges of the passage point act on the operating element and not on the light guide.
  • FIG. 1 shows a view of an embodiment of an inventive arrangement from a viewing angle inside a (cut) housing 3.
  • the adjustable unit 6 was recessed for better visibility of the other arrangement components.
  • FIG. 2 shown view of the same embodiment from a different angle, however, the adjustable unit 6 is present.
  • FIG. 3 Fig. 3 illustrates a cross-section of another embodiment of the invention.
  • the exemplary embodiments shown use the arrangement according to the invention for adjusting a potentiometer 6, which is arranged on a printed circuit board 5 in the interior of the (only schematically indicated) housing 3. With the circuit board 5 is the potentiometer 6 by not shown electrical connections in contact.
  • the potentiometer 6 here has a ring shape and accommodates a waveguide acting as a light guide 1 in its central receiving opening.
  • a rotationally free coupling of shaft 1 and potentiometer 6 at least one end of the shaft 1 and the receiving opening are designed as external or internal square or hexagonal, so that rotational movements of the optical fiber 1 are transmitted to the potentiometer 6 or parts of the potentiometer 6 can be.
  • some embodiments provide no fixed coupling of the light guide 1 with the potentiometer 6, so that the shaft 1 does not transmit to it acting tensile and compressive loads on the potentiometer 6. This contributes to the avoidance of mechanical loads on the potentiometer 6 and the light guide 1.
  • an adjustment of the potentiometer 6 takes place by corresponding conversion of the transmitted via the light guide 1 rotational movement.
  • the adjustment range corresponds of the potentiometer 6 or the range of rotation of its sliding contact of a 360 ° rotation of the optical waveguide 1 or of the rotary knob 2.
  • the over-rotation lock 4 comprises a set around a knob 2 and light guide 1 and with these force and / or positively connected ring having a projection on its outer circumference. During a rotational movement of the light guide 1, the over-rotation lock 4 rotates.
