Kneading tool, especially kneading hook for Hanshalts kitchen machines or the like.

The innovation relates to a kneading tool, in particular a kneading hook for household kitchen machines or the like, with a shaft that can be inserted into a coupling sleeve of the kitchen machine and is provided with a locking device at its upper end, as well as an adjoining kneading arm bent from a wire rod .

Known kneading tools of the above-mentioned to have in general • In a kneading arm bent from a round wire rod on, on the upper end of which is attached a separate shaft. On this shaft sits part of a locking device with which the kneading device can be fastened in the coupling sleeve of the household cow's machine. It is common to use the shaft of the Kneading tool from a profile rod, which in a correspondingly shaped coupling sleeve of the food processor is pluggable. In this known version of the kneading tool from sswel assembled parts, it is necessary the shaft with the kneading arm particularly carefully and firmly connect, because only in this way can the sometimes considerable torques occurring during operation without destruction of the connection. The connection is done in many cases by soldering or welding at a special joint and is therefore cumbersome and expensive.

In certain cases, in which particularly high torques are to be transmitted, it is also common to use a shaft and a kneading tare Manufacture from one piece by pressing or forging. The pressing or forging of such a kneading tool however, requires a particularly high level of effort.

The object of the present innovation is therefore to design the parts to be joined in a kneading tool of the type described in more detail at the outset in such a way that the shaft and the kneading arm can be securely connected to one another in a simple manner.

This object is achieved according to the present innovation in that the upper end portion of the in a tubular Section of the shaft fitted wire rod together is bent with this and is thus firmly connected to the shaft.

By winning together the rehr-like section of the Sleeve with the end section of the wire rod fitted into it, the kneading arm can be quickly and easily managed easy to attach to the shaft.

An advantageous further development of the subject of the innovation is achieved in that the curvature of the wire rod is designed as a spatial curvature with changing radii, at least in the upper region of the tubular section.

In this way, a particularly secure and perfect connection between the shaft and the kneading hook is achieved and prevents the end portion of the wire rod from being pulled out of the tubular portion over time can.

Further advantageous features of the innovation characterized in the claims are explained in the following description with reference to a kneading tool for a household kitchen appliance shown in the accompanying drawing as a Ausführungsbei. Show it:

Fig. 1 is an assembled from a shaft and a kneading arm and kneading hooks for a household food processor formed by bending the two parts together, partially in section to make the joint visible,

FIG. 2 shows the kneading hook according to FIG. 1 in a position rotated by a right angle with respect to these and

3 shows the kneading hook in a view from above.

This, like a push button ice in a corresponding holder can be inserted in the coupling sleeve Button 13 is designed so that it can be plugged in of the shaft 11 in the sleeve opposes a slight resistance, while a greater force is required to pull it out is. At the lower end of the sea-square profile Shank 11 closes a tubular section

14 into which the upper end of a round wire rod curved kneading arm 15 is fitted.

When making the dough hook Io, the first straight upper section of the kneading arm 15, which is bent from a round wire rod, into the bore of the initially likewise still straight tubular section 13 at the lower end of the Shank 11 fitted and then bent together with the tubular portion 14. In this way, the kneading arm 15 becomes firmly connected to the shaft 11. The curvature of the protruding with a straight end into the shaft 11 The wire rod is designed in the upper area of the tubular section 13 as a spatial curvature with changing radii, • o that the kneading arm connected to the shaft 11 by bending
