ABSTRACT:
DESCRIPTION
The invention relates to an implement for cutting garlic, onions or similar vegetables, having an inner part which has an accommodating chamber with a cutting grid which is arranged at one end and is intended for the substance which is to be cut, having a top housing part which has a ram and by means of which the accommodating chamber can be closed at the other end, having a housing body which has a blade and in which the inner part is accommodated in a rotatable manner, and having threaded means which, as a result of rotation of the top housing part, allow the ram to move into the accommodating chamber of the co-rotating inner part or move out of the same, it being possible for the threaded means to be engaged or disengaged by means of adjustment means.
DE 198 05 933 C 1 discloses a garlic cutter having the features specified in the introduction. This garlic cutter has a housing body which bears a blade on its underside. Also provided is a top part with a ram fastened thereon, which, in the operating state, executes an axial movement toward a co-rotating cutting grid upon rotation in relation to the housing body. In order that the garlic cutter can be rendered operable more quickly following the filling operation, the fruit is committed without any adverse effect and the garlic cutter can also be quickly reopened and cleaned, an inner body is provided, the latter accommodating the garlic and being mounted in a rotatable manner in the housing body. The inner body has a cutting grid, a ram arranged on a spindle penetrating into the inner body.
The garlic cutter is further equipped with adjustment means which ensure engagement in the spindle in the operating state and allow a free longitudinal displacement of the spindle in the open state. The means are designed as a union nut which is arranged on the housing body and has a mating thread for the spindle. The union nut is fastened on the housing body by means of a bayonet closure. The mating thread is arranged on the inside of a spring ring which, by way of the union nut, is engaged with the thread of the spindle in the operating state and disengaged in the open state. This measure allows the ram to be moved rapidly into the operating position directly above the substance which is to be cut. The union nut is then latched and the ram, by rotation of the top part, is fed to the substance which is to be cut, as a result of which the substance is cut up by the cutting grid and the blade. For rapid opening, the union nut is unlatched again, with the result that the ram can be rapidly removed and the garlic cutter cleaned. Although this garlic cutter has proven very successful in practice, there is a need for further improvement.
The object of the invention is to develop an implement for cutting garlic or similar vegetables, and having the features specified in the introduction, to the extent that, as well as having a construction of straightforward design, it can be handled, as well as cleaned, easily and quickly.
This object is achieved according to the invention, in the case of the implement having the features specified in the introduction, essentially in that the adjustment means is arranged in an axially displace able manner on the top housing part, and engages the threaded means in a first axial position and disengages the threaded means in a second, different axial position.
Since the adjustment means is arranged on the top housing part, this results in a very simplified construction in design terms, handling of the implement being simplified at the same time. In this respect, it should also be emphasized that the adjustment means is actuated in the axial direction, which further benefits the handling. For operating and for opening the implement, the adjustment means can be displaced extremely easily in the axial direction respectively from the second axial position into the first axial position and vice versa, as a result of which the threaded means are either engaged or disengaged. If the threaded means are engaged, the ram can be moved, by straightforward rotation of the top housing part, in the direction of the substance which is to be cut. If the implement is to be opened following completion of the cutting operation, the adjustment means is transferred, by straightforward axial displacement, into the second position, with the result that the ram can be drawn off from the implement together with the top housing part. Conversely, for cutting the substance located in the accommodating chamber, the ram is introduced with the top housing part into the accommodating chamber, with the adjustment means located in the second position, until the ram is positioned directly above the substance which is to be cut. The adjustment means is then transferred from the second axial position to the first axial position and the top housing part is made to rotate, whereupon the ram is moved in the direction of the substance which is to be cut and said substance is cut up into cubes by means of the cutting grid and of the blade, which rotate relative to one another.
A first advantageous configuration of the invention is distinguished in that the second axial position of the adjustment means is arranged closer to the head of the top housing part than the first axial position. It is precisely for the purpose of cleaning the implement that this measure has proven particularly favorable from the point of view of economics since the user, by subjecting the top housing part to a pulling force, transfers the adjustment means as it were automatically from the first axial position to the second axial position and disengages the threaded means, with the result that the top housing part together with the ram can be removed easily from the implement. Conversely, once the accommodating chamber has been filled with the substance which is to be cut, the top housing part is introduced into the accommodating chamber together with the ram by virtue of a pushing force being exerted, whereupon the adjustment means is transferred once again more or less automatically from the second position into the first axial position, in which the threaded means engage with one another.
According to another advantageous configuration, the top housing part grips over the housing body, the threaded means being formed by an internal thread of the top housing part and an external thread of the housing body. This measure results in an extremely straightforward construction of the implement according to the invention which, in addition to the adjustment means, has just three separate parts.
It has also proven extremely advantageous for the adjustment means to ensure the engagement of the internal thread in the external thread in the first position and to allow a longitudinal displacement of the top housing part in relation to the housing body in the second position. This measure makes it possible, once the accommodating chamber has been filled, for the top housing part to be transferred rapidly into an operating position in which the ram is arranged directly above the substance which is to be committed. The adjustment means is then transferred into the first position, in which the internal thread and external thread engage with one another, as a result of which, upon rotation of the top housing part, the ram is introduced further into the accommodating chamber and the substance which is to be committed is cut up by the cutting grid and the blade.
A configuration of the adjustment means which is particularly straightforward in design terms is achieved in that the housing wall of the top housing part is formed, in the region of the internal thread, by in particular slightly outwardly oriented, preferably resiliently elastic lugs. This measure makes it possible for the threaded means to be engaged with one another by virtue of the lugs being pivoted inward and disengaged by virtue of the lugs being pivoted outward.
According to another extremely advantageous configuration of the invention, the adjustment means is designed as a ring which is guided on the top housing part, g
