Description

Die Erfindung betrifft eine Vorrichtung zum Zerkleinern von Nahrungsmitteln, wie Zwiebeln und dergleichen, mit einem über das zu zerkleinernde Gut stülpbaren Gehäuse und einem in dem Gehäuse geführten, mittels eines Stössels gegen die Kraft einer Feder nach unten verschiebbaren Messer, wobei das Messer bei der Aufwärtsbewegung durch die Führung im Gehäuse um einen Winkel zwangsläufig verdreht wird.The invention relates to a device for comminuting food, such as onions and the like, with a housing which can be slipped over the material to be comminuted and a knife which can be moved downwards by means of a plunger against the force of a spring, the knife during the upward movement is inevitably rotated by an angle through the guide in the housing.

Eine Zerkleinerungsvorrichtung dieser Art ist z.B. aus der deutschen Patentschrift Nr. 2719980 bekannt, wobei die Verdrehung des Messers dadurch erreicht wird, dass der Stössel von einer Schlingfeder umgeben ist, die ihn bei der Aufwärtsbewegung kraftschlüssig umschliesst, während sie bei der Abwärtsbewegung aufgeweitet wird und keine zwangsläufige Verdrehung bewirkt.A crushing device of this type is e.g. Known from German Patent No. 2719980, the rotation of the knife is achieved in that the plunger is surrounded by a wrap spring, which non-positively encloses it during the upward movement, while it is widened during the downward movement and does not cause any inevitable rotation.

Die bekannten Zerkleinerungsvorrichtungen haben eine Reihe von Nachteilen, wovon einer darin besteht, dass die Funktion der Schlingfeder nicht immer zuverlässig ist und, abhängig von der Reinigung und Sauberhaltung der Vorrichtung, auf dem Stössel festsitzen kann, anstatt ihn freizugeben. Aus diesem Grund wurden mehrfach Verbesserungen zur Zerlegbarkeit vorgeschlagen, damit der komplizierte Mechanismus besser zugänglich ist und gereinigt werden kann.The known shredding devices have a number of disadvantages, one of which is that the function of the wrap spring is not always reliable and, depending on the cleaning and keeping the device clean, can get stuck on the pestle instead of releasing it. For this reason, improvements to the dismantling have been proposed several times so that the complicated mechanism is more accessible and can be cleaned.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine neuartige Kupplung vorzuschlagen mit der eine zwangsläufige Fortschaltung des Messers erreicht wird.The present invention has for its object to propose a novel clutch with which an inevitable indexing of the knife is achieved.

Erfindungsgemäss wird dies erreicht durch eine Kupplung aus zwei konzentrisch zueinander angeordneten, im wesentlichen ringförmigen Elementen, von denen ein Element auf der dem zweiten Element zugewandten Stirnfläche über den Umfang verteilt eine Anzahl von einseitig angeschrägten Zähnen aufweist, während das zweite Teil auf der dem ersten zugewandten Stirnfläche mindestens zwei oder mehrere federnde und in die senkrechte Flanke der Zähnung eingreifende Klinke aufweist wobei das erste Kupplungsteil in spiralig geführten Nuten des Gehäuses gleitet, während das zweite Kupplungsteil fest mit dem Betätigungsmechanismus verbunden ist.According to the invention, this is achieved by a coupling of two concentrically arranged, essentially annular elements, of which one element on the end face facing the second element has a number of teeth tapered on one side over the circumference, while the second part on the one facing the first Front surface has at least two or more resilient pawl and engaging in the vertical flank of the teeth, the first coupling part sliding in spirally guided grooves of the housing, while the second coupling part is firmly connected to the actuating mechanism.

Wie Fig. 1 zeigt, besitzt die Vorrichtung ein Gehäuse 1, das aus einem Oberteil 2 und einem Unterteil 3 besteht. Das Unterteil ist mit dem Oberteil mittels eines Bajonettverschlusses oder dergleichen verbunden. Das Gehäuseoberteil 2 besitzt eine nach oben offene, Kammer, die durch eine mit der Gehäuseaussenwand einstückig verbundene zylindrische Wand 4 und einen Boden 5 gebildet wird. Der Boden 5 besitzt eine von einem zylindrischen Ansatz 6 umgebene Oeffnung 7. Auf ihrer inneren Oberfläche weist die zylindrische Wand spiralig geführte Nuten 8 auf, die aus Fig. 4 ersichtlich sind. Die aus der zylindrischen Wand 4 gebildete Kammer dient der Aufnahme des Betätigungsmechanismus 9.1 shows, the device has a housing 1, which consists of an upper part 2 and a lower part 3. The lower part is connected to the upper part by means of a bayonet catch or the like. The upper housing part 2 has a chamber which is open at the top and which is formed by a cylindrical wall 4 and a base 5 which are integrally connected to the outer wall of the housing. The bottom 5 has an opening 7 surrounded by a cylindrical projection 6. On its inner surface, the cylindrical wall has spirally guided grooves 8, which can be seen in FIG. 4. The chamber formed from the cylindrical wall 4 serves to receive the actuating mechanism 9.

Der Betätigungsmechanismus besteht aus einem Stössel 11, der in der Oeffnung des Kammerbodens geführt wird. Der Stössel 11 ist fest mit einem Druckknopf 12 verbunden, der nach unten eine zylindrische Verlängerung 13 aufweist, deren äusserer Durchmesser dem Innendurchmesser der Kammer entspricht. Der Druckknopf wird auf diese Weise in der Kammer geführt.The actuating mechanism consists of a plunger 11 which is guided in the opening of the chamber floor. The plunger 11 is firmly connected to a push button 12 which has a cylindrical extension 13 downwards, the outer diameter of which corresponds to the inner diameter of the chamber. The push button is thus guided in the chamber.

Zwischen dem Kammerboden und dem Druckknopf befindet sich eine Spiralfeder 14, die den Druckknopf samt Stössel nach oben drückt.Between the chamber bottom and the push button there is a spiral spring 14 which presses the push button together with the plunger upwards.

Auf der Unterseite der zylindrischen Verlängerung des Druckknopfs befindet sich eine zweiteilige Kupplung 15, 16, die nachfolgend genauer beschrieben wird.On the underside of the cylindrical extension of the push button there is a two-part coupling 15, 16, which is described in more detail below.

Am unteren Ende des Stössels ist ein Messerhalter befestigt. Zwischen dem Messerhalter 17 und dem Kammerboden befindet sich ein Stossdämpfer 18. Im Messerhalter ist ein an sich bekanntes wellig geformtes Hackmesser 19 befestigt.A knife holder is attached to the lower end of the ram. A shock absorber 18 is located between the knife holder 17 and the chamber bottom. A wavy-shaped cleaver 19 known per se is fastened in the knife holder.

Im Uebrigen ist in an sich bekannter Weise ein Abstreifer 21 vorgesehen, der beim Zerlegen des Gehäuses in Oberteil und Unterteil ebenfalls abgenommen werden kann. Schliesslich befindet sich auf der unteren Seite des Gehäuseunterteils 3 ein Hackteller 22 auf den das Gehäuse aufgesetzt wird.Otherwise, a wiper 21 is provided in a manner known per se, which can also be removed when the housing is disassembled into the upper part and lower part. Finally, on the lower side of the lower housing part 3 there is a chopping plate 22 on which the housing is placed.

Die genaue Ausbildung und Funktion der Kupplung ist aus den Figuren 2 und 3 ersichtlich. Die Kupplung besteht aus zwei Teilen 15, 16, die aber zusammengefügt und gegeneinander verdrehbar sind, allerdings nur in einer Richtung. Der erste Teil 15 ist in Figur 2 gezeigt und zwar in Figur 2a eine Seitenansicht teilweise geschnitten und in Figur 2b eine Aufsicht. Wie aus Figur 2a ersichtlich, besitzt das erste Kupplungsteil 15 eine flache Scheibe 23, die auf ihrer Oberseite mit einseitig angeschrägten und auf der anderen Seite steile Flanken aufweisenden Zähnen 24 versehen ist. Ueber den Umfang der Scheibe 23 sind 16 Zähne verteilt, sodass jedem Zahn ein Winkel von 22,5 Grad entspricht. Auf ihrer äusseren Peripherie besitzt die Scheibe einen zylindrischen Ansatz 25, der mit vier um 90 Grad gegeneinander versetzten zylindrischen Nocken 26 versehen ist. Der Durchmesser dieser Nocken beträgt 3,5 mm und entspricht damit der Breite der spiraligen Nuten 8 in der Kammerwand.The exact design and function of the coupling can be seen from Figures 2 and 3. The coupling consists of two parts 15, 16, which, however, are joined together and can be rotated relative to one another, but only in one direction. The first part 15 is shown in FIG. 2, specifically a side view in section 2a and a top view in FIG. 2b. As can be seen from Figure 2a, the first coupling part 15 a flat disk 23 which is provided on its upper side with teeth 24 which are beveled on one side and have steep flanks on the other side. 16 teeth are distributed over the circumference of the disk 23, so that each tooth corresponds to an angle of 22.5 degrees. On its outer periphery, the disk has a cylindrical extension 25 which is provided with four cylindrical cams 26 which are offset by 90 degrees. The diameter of these cams is 3.5 mm and thus corresponds to the width of the spiral grooves 8 in the chamber wall.

Auf ihrer Innenseite trägt die Scheibe 23 einen langen, nach oben gerichteten zylindrischen Ansatz 27, dessen Innendurchmesser grösser ist als der Aussendurchmesser des Stössels 11. Der Ansatz 27 besitzt an seiner oberen Seite eine nach oben konisch abgeschrägte Verbreiterung 28, die nach unten einen Anschlag bildet, mit dessen Hilfe die beiden Kupplungsteile zusammengehalten werden. Die Höhe des zylindrischen Ansatzes 27 entspricht der Höhe des nachfolgend zu beschreibenden zweiten Teils der Kupplung.On its inside, the disk 23 carries a long, upwardly directed cylindrical projection 27, the inside diameter of which is larger than the outside diameter of the plunger 11. The projection 27 has on its upper side an upwardly conically widened widening 28 which forms a stop at the bottom , with the help of which the two coupling parts are held together. The height of the cylindrical extension 27 corresponds to the height of the second part of the coupling to be described below.

Der zweite Teil der Kupplung ist in Figur 3 gezeigt und zwar zeigt Figur 3a eine Kombination aus Schnitt und Ansicht und die Figur 3b einen Grundriss. Es ist zu beachten, dass der Schnitt, den die Figur 3a zeigt, nicht gerade geführt ist, sondern teilweise bogenförmig verläuft. Die Schnittlinie ist in Figur 3b strichpunktiert eingezeichnet.The second part of the coupling is shown in FIG. 3, namely that FIG. 3a shows a combination of section and view and FIG. 3b shows a floor plan. It should be noted that the section shown in FIG. 3a does not is guided straight, but runs in part arcuate. The section line is drawn in dash-dot lines in FIG. 3b.

Das zweite Kupplungselement 16 besteht im wesentlichen aus einer zylindrischen Aussenwand 29, die mit zwei einander gegenüberliegenden achsparallelen Vorsprüngen 31 versehen ist. Diese Vorsprünge 31 dienen dem Einfügen des zweiten Kupplungsteils 16 in entsprechende Nuten 30 in der Innenwand der Verlängerung des Druckknopfs 12. Einstückig mit der zylindrischen Wand 29 verbunden sind Teile eines Bodens 32, und zwar erstrecken sich diese Teile einander gegenüberliegend jeweils über 90o. An diesen Bodenteilen sind wiederum nach oben gerichtete, ebenfalls einen Winkel von 90o umfassende Ansätze 33 vorgesehen, deren Höhe dem Ansatz des ersten Elements bis zum Anschlag der Verbreiterung entspricht. Der Abstand dieser beiden viertelzylindrischen Ansätze 33 voneinander entspricht dem Aussendurchmesser des Ansatzes des ersten Elements.The second coupling element 16 essentially consists of a cylindrical outer wall 29 which is provided with two axially parallel projections 31 lying opposite one another. These projections 31 are used to insert the second coupling part 16 into corresponding grooves 30 in the inner wall of the extension of the push button 12. Parts of a base 32 are connected in one piece to the cylindrical wall 29, and these parts extend opposite one another in each case over 90 ° . On these base parts there are in turn upwardly directed lugs 33, also comprising an angle of 90 ° , the height of which corresponds to the lug of the first element until the widening stops. The distance between these two quarter-cylindrical projections 33 corresponds to the outside diameter of the projection of the first element.

Die Bodenelemente setzen sich jeweils in sich ebenfalls über 90o erstreckende Zungen oder Klinken 34 fort, die nicht mit der Aussenwand 29 verbunden sind und schräg nach unten gerichtet sind. Infolge der Materialeigenschaft haben diese Zungen die Möglichkeit nach oben zu federn. Diese Zungen sind so ausgebildet, dass sie in die steilen Flanken der Zähne 24 eingreifen, wenn die beiden Kupplungsteile zusammengesetzt sind.The floor elements in contact each also about 90 o extending tongues or pawls 34 on, which are not connected to the outer wall 29 and obliquely directed downwards. Due to the material properties, these tongues have the option of springing upwards. These tongues are designed such that they engage in the steep flanks of the teeth 24 when the two coupling parts are assembled.

Die Funktion der Kupplung ist wie folgt. Wenn der Druckknopf von Hand nach unten gedrückt wird, wird der untere Teil der Kupplung durch die spiralförmigen Nuten verdreht. Da der Druckknopf aber von der betätigenden Hand festgehalten wird und sich nicht drehen kann, gleitet der obere Kupplungsteil mit den Zungen über die Schrägflächen der Zähne hinweg. Nach dem Loslassen, d.h. bei der Aufwärtsbewegung des Stössels und des Druckknopfes bewirkt der Eingriff der Zungen in die steilen Flanken der Zähne, dass eine gegenseitige Verdrehung der beiden Kupplungsteile nicht mehr möglich ist. Dadurch wird infolge der zwingenden Verdrehung des ersten Kupplungsteils durch die spiralförmigen Nuten auch der Knopf, der Stössel und damit das Messer verdreht. Jede Verdrehung beträgt 22,5 Grad, nach sechzehn Betätigungen ist eine ganze Umdrehung erreicht.The function of the clutch is as follows. When the push button is pressed down by hand, the lower part of the coupling is rotated by the spiral grooves. However, since the push button is held by the operating hand and cannot rotate, the upper coupling part with the tongues slides over the inclined surfaces of the teeth. After releasing, i.e. during the upward movement of the plunger and the push button, the engagement of the tongues in the steep flanks of the teeth means that the two coupling parts can no longer rotate relative to one another. As a result of the compulsory rotation of the first coupling part by the spiral grooves, the button, the plunger and thus the knife are also rotated. Each twist is 22.5 degrees, after sixteen operations an entire turn is achieved.

Als Material für die Vorrichtung kommen die üblichen Kunststoffmaterialien in Frage. Die Kupplung besteht vorzugsweise aus Polyoxymethylen (Delrin (R) ). Selbstverständlich sind andere abriebfeste und die nötigen elastischen Eigenschaften aufweisende Materialien geeignet.The usual plastic materials come into question as material for the device. The coupling is preferably made of polyoxymethylene (Delrin (R)). Of course, other abrasion-resistant materials with the necessary elastic properties are suitable.
