Abstract

A device for the size reduction of foodstuffs, such as onions and the like, with a housing which may be turned over the goods to be reduced in size. A knife is displaceable downwards against a force of a spring by an actuation mechanism with a push button and a plunger. The knife with the upwards movement by the guiding in the housing is rotated about an angle and by way of a positive displacement the rotation of the actuation mechanism relative to the housing is limited in one direction. The actuation mechanism includes a cap open at the bottom in which the push button is rotatably mounted, wherein the push button and the cap in the axial direction are rigidly connected to one another. An outer shaping of the actuation mechanism is completely free with the application of the cap.

Description

Die vorliegende Erfindung betrifft einen Hacker gemäss Oberbegriff des Patentanspruches 1 für Zwiebeln, sonstige Gemüse und andere Lebensmittel (CH-A-390 479).The present invention relates to a hacker according to Preamble of claim 1 for onions, others Vegetables and other foods (CH-A-390 479).

Aus der EP-B-0'345'223 der Anmelderin ist ein Hacker bekannt. Er weist ein über das zu zerkleinernde Gut stülpbares Gehäuse und ein in dem Gehäuse geführtes, mittels eines Betätigungsmechanismus mit einem Druckknopf und einem Stössel gegen die Kraft einer Feder, verschiebbares Messer auf. Das Messer lässt sich gegen die Kraft der Feder nach unten verschieben und wird bei der nachfolgenden Bewegung nach oben durch eine Führung im Gehäuse um einen bestimmten Winkel relativ zum Gehäuse verdreht. Ein zwischen Betätigungsmechanismus und Gehäuse angeordneter Fortschaltmechanismus stellt sicher, dass eine zwangsläufige Fortschaltung des Messers gewährleistet ist. Diese Zwangsfortschaltung hat sich als sehr vorteilhaft erweisen, da sie ein "auf der Stelle Hacken" des Messers verhindert. From the applicant's EP-B-0'345'223 is a Known to hackers. It indicates the goods to be shredded slipable housing and a guided in the housing, by means of an actuating mechanism with a push button and a Ram against the force of a spring, sliding knife on. The knife can be released against the force of the spring move down and will with the subsequent movement upwards through a guide in the housing around a certain one Angle rotated relative to the housing. An between Actuating mechanism and housing arranged Advance mechanism ensures that an inevitable Advance of the knife is guaranteed. This Forced advancement has proven to be very beneficial since it prevents the knife from "chopping on the spot".

Dadurch werden die Effektivität des Hackers erhöht und die gleichmässige Grössenverteilung des Hackgutes verbessert.This increases the effectiveness of the hacker and the even size distribution of the wood chips improved.

Wenn der Druckknopf von Hand nach unten gedrückt wird, wird ein unterer Teil einer Kupplung durch spiralförmige Nuten im Gehäuseinneren verdreht. Da der Druckknopf aber von der betätigenden Hand festgehalten wird und sich nicht drehen kann, wird ein oberer Kupplungsteil relativ zum unteren Kupplungsteil verdreht. Nach dem Loslassen, d.h. bei der Aufwärtsbewegung des Stössels und des Druckknopfes bewirkt der Fortschaltmechanismus, 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. Im Ausführungsbeispiel gemäss der EP-B-0'345'223 beträgt jede Verdrehung 22,5 Grad, nach sechzehn Betätigungen ist eine ganze Umdrehung erreicht.When the push button is pressed down by hand, a lower part of a coupling by spiral grooves in the Twisted housing interior. Since the push button is from the hand is held and do not turn can, an upper coupling part is relative to the lower Coupling part twisted. After letting go, i.e. in the Upward movement of the plunger and the push button causes the indexing mechanism that a mutual twist of the two coupling parts is no longer possible. Thereby is due to the mandatory twisting of the first Coupling part through the spiral grooves also the button, the pestle and thus the knife twisted. in the Embodiment according to EP-B-0'345'223 is each Twist 22.5 degrees, after sixteen operations is one full revolution reached.

Ein Hacker gemäss der GB-A-821'493 unterscheidet sich vom vorgenannten Hacker im wesentlichen durch einen anderen Fortschaltmechanismus.A hacker according to GB-A-821'493 differs from aforementioned hackers essentially by another Advancing mechanism.

Den bekannten Hackern ist jedoch gemeinsam, dass die nötige radiale Drehbeweglichkeit und die ebenfalls nötige vertikale Auf- und Abbeweglichkeit des Betätigungsmechanismus durch seine kreiszylindrische äussere Form erreicht wird.
Gemüsehacker dieser Form sind schon seit vielen Jahren auf dem Markt erhältlich. Der Betätigungsmechanismus stellt nicht nur einen wesentlichen funktionellen Teil dar, sondern prägt auch das äussere Erscheinungsbild der Geräte ganz entscheidend. Bei den bekannten Hackern ist es jedoch dem Hersteller nicht möglich die äussere Form des Betätigungsmechanismus entscheidend zu verändern obwohl dies aus gestalterischen und ergonomischen Gründen erwünscht wäre.However, the known hackers have in common that the necessary radial rotational mobility and the likewise necessary vertical up and down mobility of the actuating mechanism is achieved by its circular cylindrical outer shape.
Vegetable choppers of this form have been available on the market for many years. The actuating mechanism not only represents an essential functional part, but also has a decisive influence on the external appearance of the devices. With the known hackers, however, it is not possible for the manufacturer to change the outer shape of the actuation mechanism decisively, although this would be desirable for design and ergonomic reasons.

Bei den Hackern mit Zwangs-Fortschaltmechanismus, wie sie zum Beispiel aus der EP-B-0'345'223 bekannt sind, darf der Betätigungsmechanismus wie oben bereits ausgeführt beim Hacken vom Benutzer nicht festgehalten werden, sondern muss während der Aufwärtsbewegung losgelassen werden um die Radialverdrehung des Betätigungsmechanismus zu erlauben. Ein kontinuierliches Festhalten des Betätigungsmechanismus beim Hacken verhindert die Fortschaltung und kann sogar zum Blockieren oder Beschädigungen des Fortschaltmechanismus führen. Es wird versucht Fehlbedienungen zu vermeiden indem mit Bedienungshinweisen auf den Verpackungen der bekannten Hacker die Benutzer zum korrekten Gebrauch angehalten werden. Diese Hinweise werden jedoch teilweise übersehen oder nicht beachtet so dass es dennoch zu Fehlbedienungen kommen kann. For hackers with a forced advance mechanism, such as those used for Example known from EP-B-0'345'223, the Actuating mechanism as stated above for Hacking must not be held by the user, but must be released during the upward movement around the To allow radial rotation of the actuating mechanism. On continuous holding of the actuating mechanism at Chopping prevents advancement and can even be used for Blocking or damage to the advance mechanism to lead. An attempt is made to avoid incorrect operation by with operating instructions on the packaging of the known Hackers are urged to use them correctly. However, this information is sometimes overlooked or not note that incorrect operation can still occur.

Es ist daher die Aufgabe der vorliegenden Erfindung einen Hacker zur Verfügung zu stellen, der diese Nachteile behebt.It is therefore the object of the present invention To provide hackers that address these drawbacks.

Erfindungsgemäss wird dies durch eine Vorrichtung gemäß dem Anspruch 1 erreicht. Die Kappe, die vom Benutzer beim Hacken gehalten wird, weist somit eine von der Kreisform abweichende Gestalt auf, womit sowohl ästethischen wie auch ergonomischen Anforderungen an die formliche Gestaltung rechnung getragen werden kann.According to the invention, this is achieved by a device according to claim 1 reached. The cap made by User is held while chopping, thus has one of the Circular shape deviating shape, with which both aesthetic as well as ergonomic demands on the formal design can be taken into account.

Wie aus der Fig. 1 hervorgeht, besitzt der erfindungsgemässe Hacker ein Gehäuse 1, das aus einem Oberteil 2 und einem Unterteil 3 besteht. Das Unterteil 3 ist mit dem Oberteil 2 mittels eines Bajonettverschlusses oder dergleichen verbunden. Das Gehäuseoberteil 2 setzt sich aus einer Gehäuseaussenwand 20, einem darin angeordneten nach oben offenen zylindrischen Einsatz 4 und einem einstückig mit dem Einsatz 4 verbundenen Boden 5 zusammen. Der Boden 5 besitzt eine von einem zylindrischen Ansatz 6 umgebene Oeffnung 7. Auf ihrer inneren Oberfläche weist die zylindrische Wand des Einsatzes 4 wendelförmig geführte Nuten auf. Die aus der zylindrischen Wand 4 gebildete Kammer dient der Aufnahme der drehbeweglichen Anteile des Betätigungsmechanismus 9.
Der Betätigungsmechanismus umfasst einen Stössel 11, der in der Oeffnung 7 des Kammerbodens 5 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 Einsatzkammer entspricht. Der Druckknopf wird auf diese Weise in der Kammer geführt.
Zwischen dem Kammerboden 5 und dem Druckknopf 12 befindet sich eine Spiralfeder 14, die den Druckknopf 12 samt Stössel 11 nach oben drückt.
Des weiteren umfasst der Betätigungsmechanismus eine Kappe 40 die über den Druckknopf 12 gestülpt ist. Die Seitenwände 41 der Kappe 40 sind von der zylindrischen Verlängerung 13 des Druckknopfes beabstandet, und bilden mit diesen einen Aufnahmeraum 19. Befindet sich der Betätigungsmechanismus, wie in der Figur 1 dargestellt in einer oberen Ruheposition, so kommt ein oberer Bereich des zylindrische Einsatzes 4 im Aufnahmeraum zu liegen. Wird der Betätigungsmechanismus nach unten gedrückt, so dringt der zylindrische Einsatz 4 nach oben in den Aufnahmeraum 19 ein.
Die Kappe ist, wie aus der Figur lc ersichtlich, im Querschnitt rechteckig. Entsprechend ist im Gehäuseoberteil 20 eine rechteckige Oeffnung 21 angebracht, so dass im Zusammengebauten Zustand der Gehäuseoberteil 2 von der Kappe 4 und den weiteren innenliegenden Teilen des Betätigungsmechanismus durchsetzt wird.
In der Figur 1a ist gezeigt, dass der zylindrische Druckknopf 12 in einem oberen Bereich drehbeweglich in der Kappe 40 gehalten ist. In einem bevorzugten Ausführungsbeispiel, wie es in der Figur 1b dargestellt ist, ist ein Kappendeckel 43 zur Halterung des Druckknopfes 12 mit nach unten vorspringenden Zungen 42 versehen. Die Zungen 42 sind mit einer inneren Ringnut 44 versehen, in die eine korrespondierende Ringwulst auf der Aussenwand des Druckknopfes 12 eingreifen kann.
In der Figur 1a ist eine weitere vorteilhafte Ausführungsform des erfindungsgemässen Hackers dargestellt, bei dem der Druckknopf mit einer Ringnut und die Zungen 42 mit entsprechenden Wülsten versehen sind. Beim Zusammenbau des Hackers kann die Kappe einfach soweit über den Druckknopf gestülpt werden, bis die Wülste in die Ringnut einrasten. Der Druckknopf 12 ist dadurch in der Kappe 4 drehbeweglich um die Gerätehauptachse A gehalten ohne dass eine Relativbewegung der beiden Teile in vertikaler Richtung zueinander möglich wäre.
Diese Art der Lagerung des Druckknopfes in der Kappe erlaubt es Kappen mit jeder beliebigen Querschnittsform zu verwenden. Neben den in den Figuren 2 und 3 dargestellten rechteckigen und Quadratischen Querschnitten können auch dreieckige, sternförmige, herzförmige oder völlig unregelmässige Querschnittsformen gewählt werden. Der Gestaltungsfreiheit sind nur insoweit Grenzen gesetzt, als die Kappe 4 mindestens noch den Druckknopf 12 und den zylindrischen Einsatz 4 aufnehmen können muss. As can be seen from FIG. 1, the hacker according to the invention has a housing 1 which consists of an upper part 2 and a lower part 3. The lower part 3 is connected to the upper part 2 by means of a bayonet catch or the like. The upper housing part 2 is composed of an outer wall 20 of the housing, an upwardly open cylindrical insert 4 arranged therein and a base 5 which is integrally connected to the insert 4. The bottom 5 has an opening 7 surrounded by a cylindrical extension 6. On its inner surface, the cylindrical wall of the insert 4 has helically shaped grooves. The chamber formed from the cylindrical wall 4 serves to receive the rotatable parts of the actuating mechanism 9.
The actuating mechanism comprises a plunger 11 which is guided in the opening 7 of the chamber base 5. 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 insert chamber. The push button is thus guided in the chamber.
Between the chamber bottom 5 and the push button 12 there is a spiral spring 14 which presses the push button 12 together with the plunger 11 upwards.
Furthermore, the actuating mechanism comprises a cap 40 which is put over the push button 12. The side walls 41 of the cap 40 are spaced apart from the cylindrical extension 13 of the push button and form a receiving space 19 therewith. If the actuating mechanism is in an upper rest position, as shown in FIG Recording room to lie. If the actuating mechanism is pressed downward, the cylindrical insert 4 penetrates upward into the receiving space 19.
As can be seen from FIG. 1c, the cap is rectangular in cross section. Correspondingly, a rectangular opening 21 is provided in the upper housing part 20, so that in the assembled state the upper housing part 2 is penetrated by the cap 4 and the further inner parts of the actuating mechanism.
It is shown in FIG. 1a that the cylindrical push button 12 is held in the cap 40 so that it can rotate in an upper region. In a preferred exemplary embodiment, as shown in FIG. 1b, a cap cover 43 for holding the push button 12 is provided with tongues 42 which project downwards. The tongues 42 are provided with an inner annular groove 44, into which a corresponding annular bead on the outer wall of the push button 12 can engage.
A further advantageous embodiment of the chopper according to the invention is shown in FIG. 1a, in which the push button is provided with an annular groove and the tongues 42 are provided with corresponding beads. When assembling the chipper, the cap can simply be put over the push button until the beads snap into the ring groove. The push button 12 is thus held in the cap 4 so as to be rotatable about the main axis A of the device without a relative movement of the two parts in the vertical direction to one another being possible.
This type of storage of the push button in the cap allows caps of any cross-sectional shape to be used. In addition to the rectangular and square cross sections shown in FIGS. 2 and 3, triangular, star-shaped, heart-shaped or completely irregular cross-sectional shapes can also be selected. The freedom of design is limited only to the extent that the cap 4 must be able to accommodate at least the push button 12 and the cylindrical insert 4.

Auf der Unterseite der zylindrischen Verlängerung 13 des Druckknopfs 12 befindet sich eine zweiteilige Kupplung 15, 16, die das Kernstück des Zwangsfortschalt-Mechanismus bildet.
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.
Im Übrigen ist in an sich bekannter Weise ein Abstreifer 21 vorgesehen, der beim Zerlegen des Gehäuses in Oberteil und Unterteil ebenfalls abgenommen werden kann, was die Reinigung erheblich vereinfacht. Schliesslich befindet sich auf der unteren Seite des Gehäuseunterteils 3 ein Hackteller 22 auf den das Gehäuse aufgesetzt wird.
Die genaue Ausbildung und Funktion der Kupplung ist aus der EP-B-0'345'223 bekannt. Die Kupplung besteht aus zwei Teilen 15, 16, die aber zusammengefügt und in einer Richtung gegeneinander verdrehbar sind.
Das zweite Kupplungselement 16 besteht im wesentlichen aus einer zylindrischen Aussenwand, die mit zwei einander gegenüberliegenden achsparallelen Vorsprüngen versehen ist. Diese Vorsprünge dienen dem Einfügen des zweiten Kupplungsteils 16 in entsprechende Nuten 30 in der Innenwand der Verlängerung des Druckknopfs 12. On the underside of the cylindrical extension 13 of the push button 12 there is a two-part clutch 15, 16, which forms the core of the positive advance mechanism.
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.
In addition, a scraper 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, which considerably simplifies cleaning. Finally, on the lower side of the lower housing part 3 there is a chopping plate 22 on which the housing is placed.
The exact design and function of the clutch is known from EP-B-0'345'223. The coupling consists of two parts 15, 16, which are joined together and can be rotated in one direction.
The second coupling element 16 consists essentially of a cylindrical outer wall which is provided with two axially parallel projections lying opposite one another. These projections serve to insert the second coupling part 16 into corresponding grooves 30 in the inner wall of the extension of the push button 12.

Wie aus der obigen Beschreibung hervorgeht, führt die Kappe 4 beim Gebrauch des Hackers 1 keine Drehbewegung relativ zum Gehäuseoberteil 2 durch. Sie kann daher vom Benutzer ohne negative Auswirkung auf die Funktion des Fortschaltmechanismus sowohl bei der Abwärts- wie auch bei der Aufwärtsbewegung kontinuierlich festgehalten werden. Ein Bedienungsfehler beim Hacken ist dadurch fast ausgeschlossen.As can be seen from the above description, the cap 4 when using the chopper 1 no rotation relative to Upper housing part 2. It can therefore be used by the user without negative impact on the function of the Advance mechanism in both the down and in the upward movement are continuously held. On This almost eliminates operating errors when chopping.
