Definitions

  • the invention relates to an adjusting device according to the preamble of claim 1.
  • the suction power of vacuum cleaners can be changed continuously to adapt to the object to be cleaned.
  • a lower suction power is required for cleaning lighter fabrics such as curtains than for cleaning textile floor coverings that have to be cleaned with full suction power.
  • Rotary potentiometers have proven to be particularly advantageous because of their compact and therefore only taking up little space. These have an adjusting spindle which can be rotated about its axis of rotation and with which the suction power can be changed. With a hub coaxial to the adjusting spindle and provided with a screw thread and a screw nut, a secure attachment of a rotating resistor is achieved in a simple manner.
  • the holding part is formed by a device housing of the vacuum cleaner, and the adjusting spindle of the rotary potentiometer / is guided to the outside through a bore in this housing.
  • the handle is directly connected to the adjusting spindle, so that the adjusting spindle and thus the rotary potentiometer can easily be damaged if the operator vacuuming with the handle on furniture, door frames or the like. hangs or bumps.
  • the rotary potentiometer can therefore be so severely damaged under certain circumstances that it is unusable and must be replaced with a new one, which is associated with considerable costs.
  • the invention has for its object to design an adjustment device of the type described above so that damage to the rotary potentiometer by bumping or improper operation of the handle is avoided properly and the device is structurally simple and inexpensive.
  • the handle is designed as a slide and the adjusting spindle is not connected directly to the threatening potentiometer but via the drive part. This prevents excessive forces that act on the handle when it is knocked on or caught and improperly operated on the handle are not transmitted directly to the adjusting spindle and thus to the rotary potentiometer. Rather, these forces are absorbed over a large area by the drive part, so that at most the drive part could be damaged, but this is much cheaper and can be replaced more easily than the expensive rotary potentiometer.
  • the adjusting device according to FIGS. 1 to 3 consists of a holding part 1, which receives a rotary potentiometer 8 with an adjusting spindle 9 and a drive part 10 rigidly connected to the adjusting spindle.
  • the holding part 1 has a U-shaped cross-section with an upper longitudinal wall 6 formed by the crosspiece of the U-cross-section and long and short side walls 2, 3 and 4.
  • the one short side wall 4 has an extension 7 projecting into the clear cross section of the holding part, in which the rotary potentiometer 8 is fastened.
  • One long side wall 2 has a longitudinal slot 17 adjoining the upper longitudinal wall 6 and extending essentially over the entire length of the side wall 2, through which a leg 16 of a U-shaped handle part 14 of a handle 15 projects.
  • the rotary potentiometer 8 has the adjusting spindle 9 running in the longitudinal direction of the holding part 1, which has a driver surface 40 at one end.
  • the adjusting spindle 9 is connected to a drive part 10 in a non-positive and positive manner via this end and the driving surface 40, which has a profiled bearing opening 12 on one end face 11 for the heating of the end of the adjusting spindle which has the driving surface 40.
  • the other end face 13 of the drive part 10 has an axially outwardly projecting bearing journal 25, with which the drive part lies in an associated bearing bore 26 of the other short side wall 5 of the holding part 1.
  • the drive part 10 is mounted in the bearing bore 26 between the short side walls 4 and 5 of the holding part 1 so as to be easily rotatable about its longitudinal axis, the longitudinal axis of the drive part coinciding with the axis of the bearing opening 12.
  • the drive part 10 is a rod with a plate body 30 which is rectangular in cross section and which is of helical design such that Angle of rotation corresponds approximately to the adjustment angle of the rotary potentiometer.
  • the handle 15 designed as a slide is slidably guided along the drive part 10.
  • the handle 15 rests with a leg 24 opposite the leg 16 on the upper side of the upper longitudinal wall 6.
  • the leg 16 of the handle part 14 rests on these sliding ribs when the handle 15 is moved, so that the contact area between the leg 16 and the upper longitudinal wall 6 is kept as small as possible. whereby the handle 15 can be moved sensitively with little effort.
  • Two cam-like guide parts 20, which are arranged at a distance from one another in the transverse direction of the holding part 1, project beyond the underside of the leg 16 of the handle part 14. Their distance from one another is slightly larger than the thickness of the drive part 1 0 , which projects with a longitudinal edge 31 between these two guide parts 20.
  • the handle 15 is moved within the longitudinal slot 17 of the holding part 1, the longitudinal edge 31 of the drive part 10 slides between the two guide parts 20 of the leg 16, as a result of which the drive part is rotated about its longitudinal axis due to its spindle-shaped design. Due to the positive and non-positive connection of the drive part 10 with the spindle 9, this is also rotated accordingly, whereby the electrical value of the rotary potentiometer 8 is changed.
  • markings or symbols 32 are provided on the upper side of the upper longitudinal wall 6 of the holding part 1, which indicate the set motor speed and thus the operating state of the vacuum cleaner.
  • the handle 15a or its handle part 14a is operatively connected to a switch 23, 23 'in both end positions. This will e.g. a device circuit is interrupted, which is closed again when the handle 15a is moved from the respective end position.
  • the device housing 1a has molded receptacles 33 and 34 for the switches on both short side walls 4a and 5a, which project downward over a longitudinal opening 35 of the holding part.
  • a pivot lever 36 and 37 is attached to each of the switches 23, 23 ′ protrude upwards into the opening 35 of the holding part 1a and extend to approximately the level of the longitudinal slot 17a of the long side wall 2a.
  • the pivot levers 36 and 37 In their non-pivoted position, in which the device circuit is closed, the pivot levers 36 and 37 form an acute angle with the adjacent short side wall 4a and 5a, respectively.
  • the handle 15a In the end positions of the handle 15a, they are pivoted up to the respective side wall, as a result of which the Circuit is interrupted.
  • the receptacle 34 on the left in FIGS. 4 and 5 is designed as an additional socket 21, and. the other receptacle 33 contains a display 22 which indicates when the filter needs to be cleaned or replaced.
  • all construction - parts of the device in the retaining part 1a combined to form an assembly can be easily assembled whereby the device outside of the vacuum cleaner unit.
  • the module can also be used in different device versions.
  • the manufacture of such an assembly is associated with low costs.
  • the embodiment according to FIGS. 6 and 7 essentially corresponds to the embodiment according to FIGS. 1 to 3.
  • the drive part 10b also has a rectangular cross section and is of a spiral configuration; however, in contrast to the previous exemplary embodiment, its axis of rotation lies outside the center of gravity of the cross-sectional area and at a short distance from a longitudinal edge 38 of the drive part opposite the longitudinal edge 31a. 10b. 1 to 3, the height of the drive part 10 corresponds to the diameter of its circumferential circle, while the height of the drive part 10b is only about half as large.
  • the embodiment according to FIG. 8 also differs from the embodiment according to FIGS. 1 to 3 only by a different design of its drive part 10c, which can be designed as a cylinder part or as a solid rod with a circular cross-section.
  • the drive part 10c has a helical guide groove 27 which, in accordance with the longitudinal edge 31 of the drive part 10 according to FIG. 2, forms a slideway for the associated guide part 20c of the handle 15c.
  • the guide part is designed as a cam 1, which positively projects into the guide groove 27 and, correspondingly, as in the embodiment according to FIG.
  • the drive portion 10c may coiled correspondingly with and also approximately extending over the whole length of the drive member rib 41, the one behind the other between two transverse to the longitudinal direction at a distance next to one another angeord- Neten, l ipp enf ö RMI g e n Guide parts 42 runs (Fig..9).
  • the drive part 10c preferably consists of two half-shells which can be produced simply and cheaply.
  • the sliding path of the handle is so long that the rotary potentiometer does not come to rest against its end stops in both end positions of the handle. Damage to the rotary potentiometer when hitting the handle or improperly operated can be avoided.
