Description

Die vorliegende Erfindung betrifft einen Eishacker gemäss Oberbegriff des Patentanspruches 1 zum Hacken, Brechen und Zerkleinern von Eis und anderen flüssigen gefrorenen Lebensmitteln.The present invention relates to an ice hacker according to the preamble of claim 1 for mincing, breaking and crushing ice and other liquid frozen foods.

Zwiebel- und Gemüsehacker sind aus der EP-B-0'345'223 und der WO01/58652 der Anmelderin bekannt. Sie weisen 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 umfasst eine zylindrische Achse an deren unterem Ende ein tellerförmiger Messerhalter aufsitzt. An der Unterseite des Messerhalters sind eine oder mehrere nach unten ragende Klingen befestigt, welche in der Draufsicht meist wellen- oder sternförmig gestaltet sind. Das Messer lässt sich gegen die Kraft der Feder nach unten verschieben bis die Klinge das Hackgut vollständig durchdrungen hat und auf eine Bodenplatte des Hackers aufschlägt. Für die einwandfreie Funktion aller bekannten Hacker ist es entscheidend, dass die unterenOnion and vegetable chopper are from the EP-B-0'345'223 and the WO01 / 58652 the applicant known. They have a housing which can be turned over the material to be shredded and a housing which is guided in the housing and is displaceable by means of an actuating mechanism with a pushbutton and a plunger against the force of a spring. The knife comprises a cylindrical axis at the lower end of a plate-shaped knife holder is seated. On the underside of the knife holder one or more downwardly projecting blades are attached, which are usually designed wave-like or star-shaped in plan view. The knife can be moved against the force of the spring down until the blade has completely penetrated the wood chips and hits a bottom plate of the hacker. For the proper functioning of all known hackers it is crucial that the lower

Schneiden oder Schneidkanten der Klingen exakt in einer horizontalen Ebene liegen.Cutting or cutting edges of the blades lie exactly in a horizontal plane.

Obwohl die Hacker nicht dazu vorgesehen sind, werden mit den bekannten Hackern häufig Eiswürfel zerkleinert um feinere Eisstückchen für Cocktails, Drinks oder zum Anrichten von Lebensmitteln zu erhalten. Das Hacken von Eis kann die bekannten Klingen sehr leicht abstumpfen und verbiegen. Verbogenen Klingen verklemmen leicht mit dem Abstreifer und beeinträchtigen dadurch die Funktionstüchtigkeit des Hackers ganz entscheidend.Although the hackers are not intended, ice cubes are often crushed with the well-known hackers to obtain finer pieces of ice for cocktails, drinks or food preparation. The chopping of ice can blunt and bend the known blades very easily. Bent blades jam easily with the scraper and thereby affect the functionality of the hacker quite crucial.

Eine gattungsgemässe Vorrichtung ist in der US-2 484 391 offenbart.A generic device is in the US 2,484,391 disclosed.

Es ist daher die Aufgabe der vorliegenden Erfindung ein Gerät zur Verfügung zu stellen, das diese Nachteile behebt.It is therefore the object of the present invention to provide a device which overcomes these disadvantages.

Der in Figur 1 dargestellte Eishacker umfasst ein Gehäuse, das aus einem mehrteiligen Oberteil 2 und einem vorzugsweise einteiligen Unterteil oder Becher 3 besteht. Der Becher 3 ist mit dem Oberteil 2 mittels eines Bajonettverschlusses 33 oder dergleichen verbunden. Ähnlich wie bei den bekannten Zwiebel- und Gemüsehacker ist im Gehäuseoberteil 2 ein Betätigungsmechanismus 4 konzentrisch gelagert und geführt, der einen Druckknopf 17 mit Kappe 18 umfasst. Im Gehäuseoberteil ist ein, mittels des Betätigungsmechanismus 4 gegen die Kraft einer Feder, verschiebbares Messer 5 angebracht. Der Betätigungsmechanismus 4 umfasst einen bekannten und daher nicht in der Figur 1 im einzelnen dargestellten Fortschaltmechanismus. Der Fortschaltmechanismus stellt sicher, dass das Messer 5 mit jeder Auf- und Abbewegung einen bestimmten Winkel um seine Längsachse rotiert. Diese Rotationsbewegung stellt sicher, dass das Messer nicht auf der Stelle hackt. Im Gegensatz zu den bekannten Gemüsehackern kann beim vorliegenden Eishacker auf einen, über das Messer stülpbaren, Abstreifer verzichtet werden.The in FIG. 1 ice hoppers shown comprises a housing which consists of a multi-part upper part 2 and a preferably one-piece lower part or cup 3. The cup 3 is connected to the upper part 2 by means of a bayonet catch 33 or the like. Similar to the known onion and vegetable chopper in the upper housing part 2, an actuating mechanism 4 is mounted and guided concentrically, which comprises a push button 17 with cap 18. In the upper housing part is a, by means of the actuating mechanism 4 against the force of a spring, slidable knife fifth appropriate. The actuating mechanism 4 comprises a known and therefore not in the FIG. 1 in detail illustrated indexing mechanism. The indexing mechanism ensures that the knife 5 rotates a certain angle about its longitudinal axis with each up and down movement. This rotational movement ensures that the knife does not chop on the spot. In contrast to the known vegetable chopper can be dispensed with the present ice hackers on a, slipped over the knife, scraper.

Das Messer 5 umfasst eine zylindrische Achse 11 an deren unterem Ende eine horizontal angeordnete tellerförmige Tragplatte 6 aufsitzt. An der Unterseite der Tragplatte sind eine oder mehrere nach unten ragende Klingen 51 befestigt, welche in der Draufsicht meist wellen- oder sternförmig gestaltet sind. Die vorliegende Erfindung kann mit allen bekannten vorgenannten Klingenformen verwirklicht werden. Aus Kostengründen werden Achse 11 und Tragplatte 6 meist einstückig im Spritzguss hergestellt, wobei die Klinge 51 in einem oberen Bereich umspritzt und dadurch unlösbar an der Tragplatte 6 befestigt ist. Um der Belastung beim Eishacken standzuhalten ist das Messer 5 vorzugweise aus stabilem Klingenblech von 0.3 bis 0.5, besonders bevorzugt 0.4 mm Dicke D gefertigt.The knife 5 comprises a cylindrical axis 11 at the lower end of a horizontally arranged plate-shaped support plate 6 is seated. On the underside of the support plate one or more downwardly projecting blades 51 are fixed, which are usually designed wave-like or star-shaped in plan view. The present invention can be practiced with all known aforementioned blade shapes. For cost reasons, axis 11 and support plate 6 are usually made in one piece by injection molding, wherein the blade 51 is overmolded in an upper region and thereby fixed inextricably on the support plate 6. To withstand the burden of ice chopping the knife 5 is preferably made of stable blade plate from 0.3 to 0.5, more preferably 0.4 mm thickness D.

Gemäß der vorliegenden Erfindung sind die Höhe HK der Klinge 51, die Höhe des Bechers HB und der durch den Betätigungsmechanismus 4 begrenzte maximale Vertikalweg des Messers 5 so gewählt und aufeinander abgestimmt, dass die Schneide 52 in ihrer untersten Stellung nicht in Kontakt mit einem Becherboden 31 kommt. Es bleibt also auch in der untersten Messerposition (in der Figur 1 strichliniert angedeutet) ein Luftspalt HS zwischen den nach unten gerichteten Spitzen von Zähnen 53 der Schneide 52 und dem Becherboden 31.According to the present invention, the height H K of the blade 51, the height of the cup H B and limited by the actuating mechanism 4 maximum vertical travel of the blade 5 are selected and matched so that the cutting edge 52 in its lowest position not in contact with a Cup bottom 31 is coming. It therefore remains in the lowest knife position (in the FIG. 1 indicated by dashed lines), an air gap H s between the downwardly directed tips of teeth 53 of the cutting edge 52 and the cup bottom 31.

Wie im weiteren noch ausgeführt wird, erfüllt der Becher eine Doppelfunktion und wird auch als Shakerunterteil benutzt. Er ist daher in einer bevorzugten Ausführungsform aus Edelstahl gefertigt. Der Luftspalt HS verhindert also ein direktes Aufschlagen der Schneide 52 mit dem Edelstahlboden und dadurch ein ungewolltes Abstumpfen der Klinge und ein Beschädigen und Zerkratzen des Bodens 31. Die Höhe des Luftspaltes HS beträgt vorzugsweise zwischen 1 und 7 mm, besonders bevorzugt zwischen 3 und 5 mm.As will be explained below, the cup fulfills a dual function and is also used as a shaker base. It is therefore made in a preferred embodiment of stainless steel. The air gap H S thus prevents a direct breaking of the cutting edge 52 with the stainless steel floor and thereby an unwanted dulling of the blade and a damage and scratching of the floor 31. The height of the air gap H S preferably is between 1 and 7 mm, more preferably between 3 and 5 mm.

Während bei den bekannten Hackern ein solcher Luftspalt als absolut unerwünscht ist, da er zu einer inakzeptablen Funktionseinschränkung führt, ist beim vorliegenden neuen Eishacker ein vollständiges Durchdringen der zu hackenden Eiswürfel nicht nötig. Die Eiswürfel werden von der stabilen Klinge 51 auseinander gesprengt, und müssen nicht vollständig durchschnitten werden.While in the known hackers, such an air gap is absolutely undesirable because it leads to an unacceptable functional limitation, a complete penetration of the ice cubes to be chopped is not necessary in the present new ice hackers. The ice cubes are blown apart by the stable blade 51, and need not be cut completely.

Diese Sprengwirkung der Klinge wird durch bevorzugte Ausgestaltungen Schneide noch unterstützt. In der in der Figur 4a und 4c gezeigten Klinge sind die Zähne beidseitig angeschliffen, wobei der Schneidenwinkel γ vorzugsweise zwischen 30 und 100° gewählt ist. Bei der in der Figur 4b und 4c gezeigten Klinge sind die Zähne nur einseitig angeschliffen und der Schneidenwinkel γ' beträgt um die 45°.This blasting action of the blade is still supported by preferred embodiments cutting. In the in the FIGS. 4a and 4c the blades are ground on both sides, wherein the cutting angle γ is preferably selected between 30 and 100 °. When in the FIGS. 4b and 4c shown blade, the teeth are ground only on one side and the cutting angle γ 'is about 45 °.

Die Verzahnung der Klinge kann je nach Klingenmaterial und Herstellungskosten gewählt werden. Zwei mögliche Zahnformen sind in den Figuren 4a und 4b dargestellt. Beim Hacken der harten und spröden Eiswürfel liegt ein entscheidender Vorteil der gezahnten Klingen, dass die Zähne, respektive die Zahnspitzen, das Eindringen in das zu hackende Eis erleichtern.The teeth of the blade can be selected depending on the blade material and manufacturing costs. Two possible tooth forms are in the FIGS. 4a and 4b shown. When chopping the hard and brittle ice cubes, a decisive advantage of the serrated blades is that the teeth, respectively the tooth tips, facilitate the penetration into the ice to be chopped.

In einer weiteren, nicht dargestellten Ausführungsform sind die Zähne, abwechselnd seitlich aus der Vertikalebene derIn a further, not shown embodiment, the teeth are alternately laterally from the vertical plane of

Klinge gebogen und verstärken dadurch nochmals die Sprengwirkung der Eishackerklinge. Die Zähne können auch um ihre Längsachse verdreht aus der Vertikalebene des Klingenbleches gebogen sein, so dass die Spitzen der Zähne im wesentlichen noch in der Ebene liegen und mit relativ kleinem Widerstand in das Eis eindringen können und die Sprengwirkung durch die Torsion der Zähne beim weiteren Eindringen enorm gesteigert ist.Blade bent and thereby reinforce the explosive effect of the ice packer blade again. The teeth may also be bent about their longitudinal axis twisted out of the vertical plane of the blade plate, so that the tips of the teeth are still substantially in-plane and can penetrate with relatively little resistance in the ice and the explosive effect by the torsion of the teeth during further penetration is increased enormously.

In der Figur 2b ist eine auf den Becher 3 angepasste Unterlage 7, vorzugsweise aus einem weichen Elastomer wie Silikon, dargestellt. Die Unterlage 7 kann fest oder lösbar mit dem Becherboden 31 und/oder einem umlaufenden peripheren Standring 32 verbunden sein. Beim Hacken verhindert sie Unterlage 7 ein Zerkrätzen der Arbeitsoberfläche, dämpft die Schläge und bewirkt eine Rutschsicherung des Hackers 1 auf einer Arbeitsoberfläche. Ist das Eis bis zur gewünschten Grösse zerkleinert, so kann der Becher 3 mittels des Bajonettverschlusses 33 vom Oberteil 2 und durch Anheben von der Unterlage 7 entfernt werden und der Oberteil 2 kann mit der Klinge auf die nun freie Unterlage 7 gestellt werden. Das Abstellen des Messers 5 auf der Unterlage 7 schützt gleichzeitig Schneide 52 und auch die Arbeitsoberfläche vor Beschädigungen. Die Unterlage 7 hat vorzugsweise einen peripher verdickten umlaufenden Randwulst 71, der verhindert, dass vom Messer 5 oder von Anderen Teilen des Oberteils 2 ablaufendes oder -tropfendes Schmelzwasser auf eine darunterliegende Arbeitsoberfläche laufen kann.In the FIG. 2b is a adapted to the cup 3 pad 7, preferably made of a soft elastomer such as silicone shown. The pad 7 may be permanently or detachably connected to the cup bottom 31 and / or a peripheral peripheral skirt 32. When chopping it prevents pad 7 scratching the work surface, dampens the shocks and causes a slip protection of the hacker 1 on a work surface. If the ice crushed to the desired size, the cup 3 can be removed by means of the bayonet lock 33 from the upper part 2 and by lifting the pad 7 and the upper part 2 can be placed with the blade on the now free pad 7. The stopping of the knife 5 on the base 7 simultaneously protects the cutting edge 52 and also the working surface from damage. The pad 7 preferably has a peripherally thickened peripheral edge bead 71, which prevents the knife 5 or other parts of the upper part of the second running or dripping meltwater can run on an underlying work surface.

Die Seitenwand 30 des Bechers 3 verbreitert sich mit einem Winkel α nach oben hin, so dass bei abgenommenem Hackeroberteil 2 ein passender Shakeraufsatz 8 klemmend befestigbar ist. Der Aufsatz 8 verfügt, wie in der Figur 3 dargestellt über eine, sich nach unten mit einem Winkel β verjüngende Seitenwand 81, welche nach oben hin in über Konus 82 in Hals 83 übergeht. Im Hals 83 ist in bekannter Manier eine Siebplatte 84 mit Ausgiessöffnungen 85 angebracht und zum verschliessen kann Deckel 9 aufgesetzt werden. Die Winkel α und β (zwischen 1 und 15°, im bevorzugten Ausführungsbeispiel 4°) und die Durchmesser von oberem Becherbereich und unterer Aufsatzwand sind so aufeinander abgestimmt, das der Aufsatz bis annähernd zum Übergang von Wand 81 zum Konus 82 in den Becher gesteckt werden kann und dadurch zum Becher hin eine ausreichende Abdichtung für Flüssigkeiten erreicht wird.The side wall 30 of the cup 3 widened at an angle α upwards, so that when the hacker upper part 2 is removed, a suitable shaker attachment 8 can be fastened in a clamping manner. The essay has 8, as in the FIG. 3 represented by a side wall 81 which tapers downwards at an angle β and which merges upward into the neck 83 via the cone 82. In the neck 83, a sieve plate 84 is attached with pouring openings 85 in a known manner and can cover 9 are closed to close. The angles α and β (between 1 and 15 °, in the preferred embodiment, 4 °) and the diameter of the upper cup area and lower top wall are coordinated so that the article are plugged into the cup until approximately the transition from wall 81 to cone 82 can and thereby the cup towards a sufficient seal for liquids is achieved.

Die Innenwand des Bechers ist vorzugsweise mit einer Gradierung in 10 Deziliterschritten versehen und der Shakeraufsatzdeckel 9 fasst vorzugsweise ein Volumen von 40 Millilitern, was einem wichtigen Mass für Barkeeper entspricht.The inner wall of the cup is preferably graduated in 10 deciliters steps, and the shaker cap 9 preferably has a volume of 40 milliliters, which is an important measure for bartenders.

The crusher (1) according to claim 1 or 2, characterized in that the teeth (53) are either i) alternately bent laterally out of the vertical plane of a blade (51) of the knife (5) or ii) are bent out of the vertical plane of the blade plate so as to be twisted about their longitudinal axis, so that the tips of the teeth (53) are substantially still located in the plane and thus reinforce the explosive effect in response to the crushing of ice.
  4. The crusher (1) according to one of the preceding claims 1 to 3, characterized in that the cup (3) comprising a shaker attachment (8) can be detachably connected so as to be substantially impermeable to liquid when the crusher upper part (2) is removed.
  5. The crusher (1) according to claim 4, characterized in that the cup (3) widens upwardly about an angle α and that the attachment (8) encompasses a side wall (81), which narrows downwardly at an angle β and which transfers upwardly into a cone (82) and in that the diameters of the upper cup area and lower attachment wall are adapted to one another in such a manner that the attachment can be inserted into the cup approximately up to the transition of wall (81) into cone (82) and in that a sufficient seal for liquids is thus attained towards the cup.
  6. The crusher according to claim 5, characterized in that the angles α and β are between 1 and 15°, preferably 4°.
  7. The crusher (1) according to one of the preceding claims 1 to 6, characterized in that it comprises a support (7), which is adapted to the cup (3), preferably consisting of a soft, slip-proof elastomer, such as silicon.
  8. The crusher (1) according to claim 7, characterized in that the support (7) encompasses a peripherally thickened revolving edge flaring (71).
