Adjusting rotary handle j in particular for household appliances _

The innovation concerns an adjusting rotary handle, especially for Household appliances, e.g. washing machines, consisting of a rotary handle and a marking or indicator ring body coupled to it, which are attached to a common setting axis of a program switch or the like.

From DE-GM 19 39 190 an adjusting rotary handle of this type for attaching to an adjusting axis is known. With this one Adjusting rotary handle, the rotary handle is inserted into the marking or indicator ring body. Between the two parts is as elastic intermediate member arranged a spring, which any inaccuracies in the production or assembly should compensate.

The innovation is based on the task of creating a two-part rotary adjustment handle of the type described above, which is easy to attach to the adjustment axis and also to loosen again and still in the assembly position both parts are securely fixed.

The solution to this problem according to the innovation is the characteristic one Part of the protection claim 1 can be found.

Appropriate further refinements of the subject of the fire are given in the subclaims.

The advantages that can be achieved with the innovation are to; see that the assembly of the two-part adjusting rotary handle on the adjustment axis can be carried out without problems and the mounted two parts of the adjusting rotary handle are fixed against each other so that they cannot twist. And a faulty one It is impossible to put both parts together with one hundred percent certainty.

An exemplary embodiment of the innovation is shown in the drawing and is described in more detail below with reference to this.

FIG. 2 shows a view of this rotary adjustment handle in the direction of arrow X in FIG. 1 25th

The two-part rotary adjustment handle shown in the drawing consists of a knurled rotary handle 1 and a thus coupled marker or indicator ring body 2. The open front of the rotary handle 1 is through a snap-in cover 3 closed. The two parts 1 and 2 of the rotary adjustment handle are not on one to one shown program switchgear belonging adjustment axis attached, the with a flat 5, a driver stop 6 for the indicator ring body 2 and a locking mechanism

The resilient locking tab 9 is part of a central formed on the rotary handle "I Adjustment axis push-on sleeve 10. The knurled rotary handle 1 goes into a cylindrical outer jacket on its rear side 11 over, which has several plug-in tabs 12 on its jacket edge, all of which are the same or at least two in Relation to the lateral surface are formed with different widths. Of the cylindrical outer jacket 11 is another cylindrical inner jacket 13 of the same length enclosed at a distance, the purpose of which will be explained in more detail later.

The marking symbols or Indicator ring body 2 has a central insertion recess 14, the diameter of which corresponds to the dimension of the cylindrical Outer jacket 11 is adapted to rotary handle 1 so that it fits into recess 14. In the center of the recess 14, an axle slip-on sleeve 15 is formed. Furthermore, slot-like recesses 16 are in the edge region of the recess 14 of the same or different lengths (depending on the design of the plug-in tabs 12) for pushing through the on the edge of the jacket of the outer jacket 11 integrally formed plug-in tabs 12 are provided. Furthermore, in the recess 14 are several radial or Radiant recesses 17 formed in which there are molded resilient tabs 18, the resilient free end merges into a hump or into an approach.

The two rotary handle parts 1 and 2 are assembled in the manner by first placing the indicator ring body 2 ^ dIe The conical marking surface points to the front or operating side is inserted on the adjustment axis 4 and then shifted until the axis slip-on sleeve 15 against the driver stop 6 on the adjustment axis 4
