Definitions

  • the invention relates to a retractable rotary knob according to the preamble of patent claim 1.
  • a retractable rotary toggle of this type is known from DE-C-2 701 017.
  • the invention has for its object to improve the retractable rotary knob of the known type by an optical display device in order to recognize or read the setting markings and the operating display even with poor room lighting or impaired visual acuity of the operator enable.
  • the invention provides a retractable rotary toggle with illuminated setting marking characters, which allows the setting marking characters to be clearly recognized even under unfavorable lighting conditions and poor visual acuity. Furthermore, this retractable rotary knob is characterized by a uniform light distribution in the entire area of the setting markings. Furthermore, an additional optical operating display can be dispensed with because the start-up of the relevant consumer is simultaneously signaled by the lighting of the marking signs.
  • With 1 is the front of a switch panel for a household appliance forming aperture plate designated, which in the illustrated embodiment made of a transparent material, for. B. glass.
  • the diaphragm plate 1 is tinted or colored from the rear so that a transparent ring area 3 remains only around a toggle opening 2.
  • the toggle opening 2 in the diaphragm plate 1 is occupied by a retractable rotary toggle 4 which is designed as a hollow cylinder and which, in its lowered position (rest position), is flush with the front of the bleno plate 1.
  • the rotary toggle 4 is slidably or displaceably on a toggle shaft 5 which is operatively connected to a switching or regulating device 7 via a plug connection 6.
  • a compression spring Inside the rotary toggle 4 is a compression spring, not visible, which is supported against the end of the toggle shaft 5 which ends in the rotary toggle and by means of which it is pressed by briefly tapping the rotary toggle 1 from its retracted latching position into the extended operating position, in which the Switching or regulating device 7 can be set.
  • the reflector body 8 has an annular reflector chamber 10 which is open towards the diaphragm plate 1 and is formed by molding. so that the reflector body and reflector chamber are integrally formed.
  • the open side of the reflector chamber 10 directed towards the rear of the diaphragm plate 1 is covered with a translucent or translucent ring body 11, which preferably consists of a prism glass or a glass ring with a prism-like surface arranged on the outside.
  • a luminous element is accommodated, which consists of several individual glow lamps 12, 12 'distributed around its circumference.
  • 12 ", 12" 'or consists of a glow lamp with a plurality of arc-shaped fluorescent glass bulbs 13, 13', 13 ".
  • the glow lamps 12, 12 ', 12 ", 12"' are arranged so as to protrude vertically from the insulating ring body 14.
  • the insulating ring body 14 also carries the electrical circuit for the glow lamps, which is designed in a known manner as a printed creation.
  • a switch position indicator 16 provided with markings made of translucent material is coupled, the ring-like marking surface 17 of which is arranged between the translucent ring body 11 of the reflector chamber 10 and the rear of the diaphragm plate 1. In front of the marking surface 17 there is the transparent ring area 3 of the diaphragm plate 1.
  • the switch position indicator 16 is also cylindrical or cup-shaped and designed so that the reflector body 8 takes it in with play.
