Definitions

  • the invention relates to a knob for actuating the setting shaft of a controller, in particular a temperature controller for refrigerators and freezers, with a coaxial guided in the setting shaft, an additional switch, such as exchange switch or the like., Control plunger, which is located in the center of the knob
  • the push button can be actuated, the rotary button being plugged onto the end of the adjusting shaft with a hub-like sleeve seated on its inside and secured there against being pulled off with a locking member.
  • Knobs for actuating the setting shaft of a controller are made of electrically insulating material for reasons of electrical safety and thus form an effective protection against contact, which prevents direct contact with the metallic setting shaft as well as those parts of the metallic controller housing adjacent to it.
  • the rotary knob can only be removed from the adjusting shaft with the aid of a tool, otherwise the controller must be grounded otherwise via an expensive assembly Ground line can not be dispensed with.
  • the rotary knob is therefore fastened to the adjusting shaft with a resilient locking member which serves as an axial securing means and which can only be unlocked by the action of the tip of a slim tool inserted through an engagement opening in the rotary knob, for example the blade of a screwdriver.
  • the adjusting shaft is provided with a switching plunger, which is guided coaxially therein, for an additional switch, such as a defrost or quick freeze switch and the like, which is equipped with an in Center of the rotary button seated push button is actuated.
  • the invention is therefore based on the object in a rotary knob of the type described in more detail to effectively secure the push button located in its center for actuating the additional switch in a simple manner and thereby to meet the relevant provisions for the protection against accidental contact of such temperature controllers.
  • the push button on its side facing the rotary knob is provided with at least two resilient lugs extending in the axial direction, which penetrate the bottom of the rotary knob provided with openings at corresponding points and with at its free ends seated barbs can be locked on the edge of the openings.
  • the push button is telescopically guided in a recess arranged in the center of the rotary button, the depth of which is greater than the maximum possible stroke of the push button limited by the length of the lugs and their barbs.
  • a regulator-lamp combination 15 with an insulated housing 16 in which, in addition to a temperature regulator 17, a light switch actuated by the door 11, not shown, and a likewise not shown Incandescent lamp are arranged in a touch-proof and water-protected manner together with corresponding connecting elements.
  • the temperature controller 17 is adjustable with a handle in the form of a rotary knob 18 provided with setting markings made of electrically insulating material, which is rotatably coupled via a coupling part described in more detail below with the setting shaft 19 of the temperature controller 17 projecting through the wall of the housing 16.
  • the rotary knob 18 is designed as a hollow cylindrical body, on the inside of which a hub-like sleeve 20 serving as a coupling member is arranged centrally.
  • This sleeve 20 is on the side provided with a radial slot 21 which extends into its bore.
  • an extension 22 on the side which, with a surface 23 milled on the adjusting shaft 19, ensures a defined seat of the rotary knob 18 on the adjusting shaft and at the same time represents an anti-rotation device.
  • a resilient rod 24 serving as a locking member, which extends across its cavity and is anchored at one end to the wall thereof, while its other end provided with a hook is close to one in the edge of the rotary knob 18 arranged engagement opening 25 protrudes.
  • the central section of the resilient rod 24 lies under spring tension in the lateral slot 21 and thus projects laterally into the bore of the sleeve 20.
  • the setting shaft 19 is provided with a switching plunger 27, which is guided coaxially therein and serves to actuate an exchange switch (not shown).
  • the rotary knob 18 has a recess 28 which is accessible from the outside and is located in its center and in which an axially displaceable push button 29 is guided telescopically in the manner of a bell button.
  • the pushbutton 29, which is likewise designed as a hollow cylinder closed on one end on its end face, has on its inside a sleeve 30 which is seated in the center thereof and which holds the free end of the switching plunger 27 is used.
  • the rotary knob 18 On its side facing the rotary knob 18, it has three resilient lugs 31 which are arranged in the corner points of an equilateral triangle and extend in the axial direction and which, when the pushbutton is inserted into the central recess 29 of the rotary knob 18, in corresponding locations in the bottom thereof provided openings 32 protrude and can be locked with barbs 33 located at their free ends at the edge thereof.
  • the depth of the recess 28 arranged in the center of the rotary knob 18 and receiving the pushbutton 29 is greater than the greatest possible stroke of the pushbutton 18 limited by the length of the lugs 31 and their barbs 33.
  • the central recess 27 is surrounded by a collar-like extension 33. This also prevents the barbs 31 from being anchored at the edge of the openings 32 by pressing in the lugs 31 when the push button is displaced outward to its end position defined by the barbs 31. In this way, the push button anchored in its operating position on the rotary knob 18 can only be released together with the rotary knob when its locking has been opened by levering out the resilient rod 24 by means of a pointed tool inserted into the rotary knob through the engagement opening 25.
