Definitions

  • the invention relates to a retractable rotary toggle unit according to the preamble of patent claim 7.
  • a pushbutton switch unit is known from US-A-31 87 602, the individual pushbuttons of which are each coupled to a guide body having a closed groove track.
  • a pin sliding in the groove of the guide body is part of a lever which is movably mounted in the housing of the pushbutton switch unit and which is held under the action of a spring element. This should push the pin into the groove.
  • the object of the invention is to constructively improve a retractable rotary toggle unit of the type described at the outset in such a way that mechanical wear on the groove track is avoided and the sinking process can be carried out with little friction and thus with less energy.
  • the proposed measures create a retractable rotary toggle unit which is largely protected against mechanical wear due to the movable mounting of the slide pin and thus has a long service life with high functional reliability in each rotary range or respective rotary position of the rotary knob.
  • the rotary toggle unit shown in the drawing consists essentially of the corrugated rotary toggle 1, on which a square, sleeve-like sliding body 2 is formed, and a guide sleeve 3 fitted into the sliding body 2, which has a central plug insert 4.
  • the plug insert 4 is used to produce a plug connection with a shaft for setting a switching or regulating device, not shown, as is used in household appliances (stoves, washing machines, dishwashers, tumble dryers, etc.).
  • a compression spring (not visible) is accommodated, which is supported against the end face of the guide sleeve 3 ending in the sliding body 2.
  • a closed groove track 6 is formed in one wall side 5 of the guide sleeve 3.
  • a locking point 7 is provided at one end of the groove track 6, while the other end of the groove track merges into a stop point 8.
  • the groove track 6 serves to guide a sliding pin 9, which is part of a movable holder 10.
  • the holder 10 has a bearing pin 11 on the upper side, which is movably guided as a bearing in a hollow rivet 12 inserted in the rotary toggle unit or the rotary toggle 1.
  • Arranged parallel to the upper side of the holder 10 is an approximately U-shaped leaf spring element 13, which is supported against the inner wall of the sliding body 2 and thus runs between the latter and the holder 10.
  • a guide groove 14 is expediently formed in the wall of the sliding body 2 for the leaf spring element 13.
  • the leaf spring element 13 is attached with its end opposite the resilient part to the bearing journal 11 of the holder 10, so that both parts (holder 10 and leaf spring element 13) are part of the rotary toggle unit and are articulated or movably coupled thereto.
  • the rotary knob 1 is in the illustrated embodiment in the extended state, which is the operating position of the rotary knob and is used to adjust the switching and control device of an electrical household appliance that can be coupled to the plug insert 4 of the guide sleeve 3.
  • the slide pin 9 is located in the area of the stop 8 at the end of the groove 6, whereby the operating position of the rotary knob 1 is fixed or fixed. If the rotary toggle 1 is to be brought into its rest position (retracted position), it is displaced axially against the force of the compression spring mentioned in the interior of the rotary toggle unit relative to the guide sleeve 3.
  • the rotary knob 1 When the rotary knob 1 is released, its rest position (retracted position) is secured.
  • the latching position can be canceled again by briefly tapping the rotary knob 1.
  • the rotary toggle 1 is then automatically brought into its operating position by relaxing the compression spring inside the rotary toggle unit.
