Definitions

  • the invention relates to a control device according to the preamble of claim 1.
  • the invention thus relates in particular to a control device for the drive motor of a vacuum cleaner, but it is also suitable for controlling other electrical or mechanical components.
  • the electrical components are usually combined on a printed circuit board, an annular potentiometer being soldered to the underside of the circuit board.
  • This ring-shaped potentiometer controls the power of the drive motor and for this purpose is penetrated by the control axis of a generally circular disk, at the other end of which a rotary knob can be arranged.
  • the potentiometer can thus be adjusted by means of the rotary movement transmitted to the circular disc by the rotary knob and thus the motor power can be controlled.
  • the rotation is usually about 270 °.
  • the present invention has for its object to develop a control device of the type under consideration so that it is space-saving and also works reliably over a long service life.
  • the control device should be cheap to produce as a mass part.
  • the control device has a flexible guide band which is formed on the outer circumference of the circular disk and is provided with a slide element at the free end.
  • the guide band is arranged between lateral guides and has such a rigidity that it rotates when the slide element is advanced in the direction of the disk and is wound on its circumference.
  • the slide element is moved in the opposite direction, the disk is correspondingly rotated in the reverse direction, the guide band being unwound again from the periphery of the disk.
  • the side guides prevent the guide from dodging bandes when it is wound on the circumference of the disc, a suitable space remaining between the lateral guides and the guide band, so that practically no frictional forces make the movement of the slide element more difficult.
  • the circular disc and the guide band are made in one piece from a suitable plastic, the manufacturing costs being extremely low.
  • the slide element can also be integrally formed on the guide band.
  • the circular disc with the integrally formed guide band is practically indestructible, so that the control device according to the invention can function properly even over a long service life of the associated vacuum cleaner.
  • Another advantage is that, depending on the size of the radius of the circular disc, the size of the sliding path of the slide element can be changed. If only a small sliding path is available, there will be a small radius chosen for the disc, so that even a small displacement of the slider element rotates the disc by a relatively large angle. With a larger radius of the disk, the angle of rotation decreases for a given length of the sliding path, so that a slower rotary movement takes place.
  • the circular disc is arranged on a plate which is penetrated by the control axis of the disc and has the lateral guides for the guide band. This plate is placed on the electrical circuit board of the vacuum cleaner.
  • the lateral guides for the guide band have a rectilinear section which contains the sliding path of the sliding element, and stops can be provided to limit the sliding path.
  • This rectilinear guide section can run essentially tangentially to the circular disk, but it can also merge into an arcuate section which runs to the circumference of the circular disk if it has a reduced diameter for a given position of the rectilinear section and the control axis.
  • the lateral guides can also at least partially encompass the outer circumference of the disk at a suitable distance, which makes it easier to wind up the tape, which can therefore not deflect laterally.
  • the lateral guides for the guide band are expediently formed by webs arranged on the plate.
  • the outer web of the guide can be formed continuously and additionally slidably receive the slide element for guiding it. To do this the slide element has a groove on its underside, in which the web is received with little play.
  • the guide for the guide band can be formed by short, spaced webs.
  • the slide element can be designed directly as an operating button and protrude through a guide slot in the vacuum cleaner housing into its interior.
  • the slider element can also be overlapped by a fork of a separate slider button, in which case the slider element can be integrally formed on the belt.
  • the slide button should have an elongated shape, which is selected so that the associated guide slot in the vacuum cleaner housing is always covered, so that no foreign particles can enter the interior of the housing through the guide slot.
  • the circular disk expediently has a cut-away section in the region of the starting point of the guide band, which section serves as free space for a molding tool for shaping the band.
  • the control device contains a circular disc 1, which is provided with a control axis 2, which engages in a potentiometer (not shown) and adjusts it as it rotates, thereby controlling the output of a drive motor.
  • a flexible control band 3 is formed on the disk 1 and a slide element 4 is located at the free end thereof.
  • the slider element 4 is a molded part with two parallel webs 5, which are overlapped by a fork of a slider button, also not shown.
  • a section 7 is cut away from the circular disk 1, which creates a free space for a molding tool for molding the guide band 3.
  • a plate 8 which receives the disc 1, wherein the control axis 2 of the disc 1 passes through a bore 9 of the plate 8.
  • the plate 8 is in turn placed on a printed switch plate, not shown, on the underside of which is the potentiometer in which the control axis 2 engages.
  • the plate 8 contains an elongated web 10 with a rectilinear section 11 and an approximately semicircular section 12 as well as short webs 13 arranged at a distance from the section 11. These webs form lateral guides for the guide band 3, which therefore cannot deflect laterally.
  • the slide element 4 (Fig. 1) contains on its underside a groove 14 which is slightly wider than the web 11, so that the slide element 4 can be slidably placed on the web 11. At the end of the web 11 there is a stop 15 for the slide element 4.
  • the slide element 4 is moved along the straight guide section 11 to adjust the potentiometer (not shown).
  • the guide band 3 which is flexible but relatively stiff, rotates the disc 1 in the direction of arrow A (FIG. 1), the guide band 3 winding onto the circumference of the disc 1 because it can neither laterally deflect between the webs 11 and 13 of the rectilinear guide section nor between the circumference of the disk 1 and the circular-arch-shaped web 12 which is slightly spaced from the circumference of the disk 1.
  • the slide element 4 moves in the opposite direction, the direction of rotation of the disk 1 changes accordingly, the guide band 3 being unwound from the circumference of the disk 1.
