Abstract

The garlic press has a casing (6), which carries a knife (8) at its bottom edge and has an upper part (2) with a stamp (12) fastened to it, which is turned about the casing opposite a cutting grid (5b) that rotates in the casing (6). An inner body (7) contains the garlic and contains the cutting grid. The stamp is fixed on a spindle (4) and is pressed against the garlic over the cutting grid by an outer nut (3), which acts on the spindle and gives it a longitudinal sliding movement.

Description

The invention relates to a vegetable cutter, in particular Garlic cutter or onion cutter or one Slicer for other vegetables, with a stamp pointing towards it or away from a cutting grid of the vegetable cutter is movable, the stamp having a plurality of pins, which can be inserted into openings in the cutting grid or can be introduced, and a plate that on the Pins sits, has.

Known devices for crushing garlic or in particular other goods are constructed in the manner of a press, the Press garlic through a perforated grid using a stamp becomes. This essentially squeezes the vegetables, by making small sausages through the holes provided Flags is processed. The garlic gets less cut, but rather pressed. Also stay relative large parts hang in the device without the holes respectively To pass through perforations of the perforated grid.

A vegetable cutter that is particularly suitable for processing Onions is thought to have the characteristics mentioned above already known from US 4,579,028. The one in this Onion cutters disclosed in the document have a stamp as a stamp Plate on which another plate is releasably attached. The further plate bears in vertical and horizontal rows a plurality of spaced pins blunt ends. One is slidably mounted on these pins Perforated plate, which with cross-shaped pins in cruciform holes of the further plate slidably guided is. The perforated plate sits frictionally on the pins and can from a position spaced from the further plate moved to a position in contact with the further plate become. This happens when most of the bulbs or the goods to be cut by the Cutting grid has been passed, then the Perforated plate comes to rest on the cutting grid. At a further forward movement of the stamp will now be the pins passed through the holes of the cutting grid so that Residues of the fruit to be cut out using the pencils be pushed out of the cutting grid. Because the perforated plate of this well-known onion cutter frictionally on the Pins can be moved, must be transferred to the perforated plate the starting position in which the perforated plate with the pins the stamp forms a substantially closed surface be pulled back completely until the cruciform Push the pins against the rear stops of the vegetable cutter. This then turns the perforated plate into the starting position front free end of the pins penetrating the perforated plate method.

These measures prove to be extremely tedious since the Stamp for every cutting operation from the totally retracted position to the fully retracted position Position is to be transferred, especially since the dimensions of the cutting goods are usually less than the maximum Stroke of the stamp. The stamp must be inserted after the cutting goods usually pretty "empty" by means of the The thread in the direction of the cutting grid until the stamp is against the fruit. Only then does the actual cutting or pressing process. After completing the Cutting or pressing is the stamp in the back opposite direction up to the outer stop move so that the perforated plate is in the starting position is transferred.

In contrast, the present invention has the object based on a vegetable cutter or other cutter for Vegetables with the characteristics mentioned above to further train that faster processing after filling of the vegetable cutter is made possible.

This task is the vegetable cutter with the input mentioned features essentially solved in that the Plate with a spring preload towards one Starting position is applied and in the starting position the plate and pins are essentially closed Form stamp area.

The stamp of this vegetable cutter according to the invention has a plurality or plurality of pens inserted into the Openings of the cutting grid are sufficient can be retracted and preferably flat at the front are, as well as a front plate, which resiliently on the stamp sits and covers the pins so that the plate is together with a closed front of the pen in the starting position Surface forms. In the starting position, until the end of the Feed movement of the stamp on the cutting grid from the Perforated plate is adhered to is essentially smooth Surface formed. If during the feed movement when cutting of the good or the clove of garlic the stamp plate is pushed up to the cutting grille at one further feed the pins through the holes or holes in the plate and grip through the cutting grid to the material to be cut completely through the cutting grid respectively to push out of this. Since the perforated plate under the Effect of spring preload in the direction of the starting position is acted upon, the perforated plate or plate automatically in the pressure relief Starting position transferred, which in turn the in substantially closed stamp area is reached. there it is not necessary to use the stamp as in the state of the Technology, to a rear, retracted position transfer to the plate or perforated plate in the Bring starting position. The closed stamp area on the one hand ensures that the Garlic by largely avoiding that Remains of garlic remain in any cavities, and on the other hand also ensures that when cleaning the smooth Stamp surface cleaned particularly quickly and easily can be.

According to a first advantageous embodiment of the invention the plate is designed as a perforated plate, being in the holes a pin is inserted into the perforated flap. To that extent is one given safe guidance of the perforated plate on the pins and on the other hand avoided that residues of the material to be cut in open holes in the perforated plate can penetrate.

In another embodiment of the invention, it is possible that the spring preload is caused by several springs, in particular compression springs, which is provided between the plate and the stamp are stretched. By appropriate Arrangement of the springs, the perforated plate can be even with the Spring preload are applied.

Furthermore, it proves advantageous that the springs each sit on a pen, creating a secure mount or fixation of the springs is guaranteed.

According to another advantageous development of the invention it is envisaged that the plate on the stamp by means of clips is adjustably attached. With these brackets the Starting position of the plate or perforated plate be defined, being in the end position of the plate or perforated plate in which the pins in the Penetrations of the cutting grid penetrate the top Hooks of the brackets are lifted off the stamp.

It is further provided that the plate during the process of Stamp strikes against the cutting grid and at one further procedures of stamping the pens into the Immerse openings in the cutting grid.

According to another advantageous embodiment, it is provided that the vegetable slicer has a housing body that carries a knife on its underside, and an upper part stamp attached to it that the stamp in the Operating state when rotating against the housing body Performs axial movement against the rotating grating, an inner body receiving the material to be cut in Housing body rotatably mounted on the inner body Cutting grid is arranged and on a spindle arranged stamp dips into the inner body.

According to a further embodiment of the invention are means provided that in the operating state for the intervention in the Spindle and a longitudinal displacement when open allow the spindle. All mechanisms are suitable as means that of a clamping or in the manner of an engagement of a piece Counter thread to the spindle can be brought into a loose position, like snap elements made of plastic or metal. It can a type of union nut can be provided, which on the Housing body is applied and, for example, by Twisting, elements for engaging in the spindle or for Letting go of the spindle brings up. Through these two different operating states are advantageously achieved, that during operation the thread of the spindle when turning the Upper part the fruit gently but strongly against the cutting grid presses, and that in the open state when the counter thread to Spindle no longer grips, the spindle is quick and easy shifted relative to the nut or via the threaded spindle can be ratcheted through. This is the onset of Upper part on the lower part and removal of the upper part can be carried out much faster from the lower part than before. On tedious screwing over the entire thread is not necessary. Due to the union nut, the spindle can be used in everyone any position on the lower part can be applied. With Can be quickly locked using the union nut the spindle can be blocked in any position, causing the Operating condition for cutting the garlic is reached. This makes handling the garlic cutter essential facilitated. First, the clove of garlic is in the lower part inserted, then the upper part with threaded rod respectively Spindle, union nut and punch in the lower part introduced. In contrast to the state of the art, this does not have to be the case here the top over the rather fine thread of the Threaded rod can be screwed in completely until the punch lies on the garlic cloves or against them suppressed. Rather, the upper part with a threaded spindle Ratchet nut rattled through until the stamp is on lies on the goods to be pressed. Then the cap nut in the locked position or in the operating position with the Brought lower part, whereby the device is ready to cut. Then the top is twisted so that the Threaded spindle using the one pressed on by the union nut Counter thread engages in the lower part and in axial movement cutting the clove of garlic or other Good causes. Also opening the garlic respectively Vegetable slicer becomes essential with these measures accelerated. All the user has to do is preferably from their bayonet catch, loosen, which the Thread is released from the spindle. Then the spindle be pulled out together with the union nut.

In a preferred embodiment, the is in the housing body rotating inner body easily for cleaning purposes removable. The inner body is preferably via locking elements snapped into the housing body and can be cleaned by simply press on the cutting grid or its bottom from below Frame can be detached. So the user can Slightly remove the inner body from the vegetable cutter and that Clean the cutting grids attached to it.

In a further preferred embodiment, this is Cutting grid easily removable from the inner body. The connection both parts are made, for example, via positive pins, which allow the two parts to snap together and one easy loosening. This will clean the cutting grid simplified again. On the other hand is with this Version with removable inner part also the housing body easy to clean with the cutting knife.

Further goals, features, configurations and advantages of the present invention result from the following Description of the embodiments with reference to the figures. there form all described and / or illustrated Features for themselves or in any meaningful combination Subject of the present invention, regardless of their Summary in the claims or their relationship.

a detail from Figure 2.

The garlic cutter according to FIG. 1 has a handle part 1 on which some recessed grips are formed so that the hand-applied torque can be better introduced. The handle part 1 sits on the upper part 2 and is opposite Housing body 6 rotatable. On the housing body 6 is the top Union nut 3 attached. The housing body 6 goes in below the knife holder 9 over. This is widened to one to form an enlarged footprint. The union nut 3 has also a corrugation with hollows to make it easier To ensure handling.

Figure 2 shows a section of the internal structure of the Garlic cutter. You can see handle 1, upper part 2 and the stamp 12 attached therein, which is connected to the spindle 4 by the Upper part 2 is attached. These components form a unit. The lower part of the device is essentially from Housing body 6 formed, the widened below Knife holder 9 as a base and on the top Union nut 3 is screwed on. Within the Housing body 6 is rotatable, the inner body 7 on a (not separately shown) metal ring mounted as a sliding element. When the upper part 2 is rotated, the inner body 7 also set in rotation. At the bottom of the Inner body 7 is attached to the frame 5a Cutting grid 5b, which is when the punch rotates 12 also rotates. Is fixed relative to the housing body 6 in contrast, the knife holder 9 with the knife 8. In the Union nut 3, a snap ring 10 is arranged, the in turn from the retaining ring 11 within the union nut 3 is held.

Figure 2 shows the garlic cutter according to the invention in State of opening, i.e. the union nut 3 is on the Housing body 6 placed, but not yet locked. Therefore the snap ring 10 is still open and with its Inside, which carries part of a counter thread, still not pressed against the thread of the spindle 4. In this Position can be the upper part 2 by the spring ring 10th be pulled through without intervening. The operating status is achieved in that the union nut 3 latches, that is is rotated against the housing body 6, whereby the snap ring 10 is compressed and its thread 10a engaged comes with the thread of the spindle 4. Then handle 1 with twisted the upper part 2, the spindle 4 screws slowly down against the snap ring 10 and presses the garlic, which is below the stamp 12 and above the Cutting grid 5b is through the cutting grid 5b. there 5b fine garlic sticks are created in the cutting grid Rotate the cutting grid 5b over the knife 8 in none Cuboids can be cut.

To open and dismantle the device, the union nut 3 again rotated a short amount of angle, causing the Snap ring 10 is released, the thread 10a no longer engages in the thread of the spindle 4 and thus the spindle 4 simply pulled out of the lower part or housing body 6 can be. The union nut 3 is preferably captive held on the spindle 4 between handle 1 and punch 12.

Figure 3 shows the garlic cutter in the open state. To can be seen that the upper part 2 from the handle 1, the upper part 2 with spindle 4 and punch 12, the Union nut 3 lies loosely above the spindle 4, in this but does not intervene. In the lower part is the housing body 6, the inner body 7 with guide grooves 7a and the cutting grid 5b to see. Likewise, the knife holder 9. In the upper part 2 is in Sectional view of the end stop 2a can be seen when the Upper part 2 with screw 4 completely screwed down on the Union nut 3 almost comes to rest, with a corresponding Cams or pins within the union nut 3 so in effect occurs that a counter rotation or a further rotation is impossible. This avoids that the stamp 12 to is pressed deep into the cutting grid 5b.

Within the union nut 3 it can be seen that the Snap ring 10 is in the open position, i.e. outward is spread, so that its inwardly acting thread does not engage in the thread of the spindle 4. The Union nut 3 is easily back and forth over the spindle 4 forth.

According to FIGS. 2a and 4, the stamp 12 has a large number of Pins 13 on which a plate 12b is assigned, so contains many holes, such as pins 13 are present. The plate 12b is fastened to the stamp 12 by means of four brackets 12a. Also shown are four springs 12c, which plate 12b Push away from the punch 12. Only when the plate 12b at the end of Pressing on the cutting grid 5b, not shown here strikes, the plate 12b is stopped by the grid and against pushed the stamp 12. The springs 12c compress pins 12 begin to protrude beyond plate 12b. They extend through the openings of the cutting grid 5b and push the last garlic remnants through the grid against the rotating knife 8 underneath Final state are the top hooks of the clips 12a Stamp 12 lifted off. The user opens the Garlic cutter or screw the punch 12 back up, the springs 12c push the plate 12b down again, so that a practically flat surface formed from the plate 12b and the front of the pins 13 is formed.

Figure 5 shows this embodiment of the stamp according to the invention again in a top view. You can see that again the spindle 4 attached stamp 12 with the round here trained pins 13 and the plate 12b with the appropriately shaped holes. The plate 12b is with the Brackets 12a attached to the stamp 12 and is from here springs not shown, of which e.g. five pieces over five Pins 13 sit, pressed down. It can be seen that the number of holes in the cutting grid 5b with the number of pins 13 matches.

Figure 6a shows a view from below of the closed Garlic cutter. You can see the knife holder 9 on the housing body 6 by means of a bayonet lock (here Left turn to open) is attached. The knife holder 9 carries a footbridge that is just outside the center of the device is arranged, and that over about half its length Knife 8 carries. This knife 8 is fixed during operation the cutting grid 5b with the stamp 12 over during operation the knife 8 turns away. You can see the pins 13, the Plate 12b and the frame 5a for the cutting grid 5b.

Figure 6b shows a detailed picture of the device shown above, wherein again both the knife 8 and the cutting grid 5b can be seen. Likewise, the pins 13 and the plate 12 b.

Figures 7a and 7b show two sections through the device according to the invention at the level of the union nut 3. The upper Part 7a shows the union nut 3 in the operating state. The Union nut 3 is with the bayonet catch on Locked housing body 6, from which the lugs 6a can be seen are. These are formed with increasing thickness, so that when rotating the union nut 3 against the housing body 6 the lugs 6a on appropriately arranged pins of the Snap rings 10 act and this inwards, on the spindle 4, to press. As a result, the thread 10a engages in the thread of the Spindle 4 and leads to an axial opening and turning Movement of the stamp 12.

The partial picture 7b shows the union nut 3 in the released state (Opening state). The lugs 6a no longer press on the corresponding projections of the snap ring 10. This is through his own elasticity popped up and expresses his Thread 10a no longer in the thread of the spindle 4. Die Spindle 4 is now from the lower part of the garlic cutter can be pulled out or pushed in easily.

FIG. 8 finally shows a detail from FIG. 3, namely in a lateral section the engagement of the Thread 10a in the thread of the spindle 4 when the Circlip 10 against the inside by forces Spindle 4 is pressed when it is in the operating position located.
