For example, an orange is divided into two halves connected by a portion of the peel. This divided part,
The skins are placed in the two holding chambers with the connected portions above the partitions. German Patent Publication no.
The tool disclosed in No. 1255877 is made of plastic and serves to cut and squeeze fruits and vegetables.
The tool includes a base and a pressure lever pivoted to the base. This lever carries a pressure plate which, during actuation of the pressure lever, moves in a frame provided on the base towards an insertion cutting plate or perforated plate removably mounted in said frame.

[Problem that the invention seeks to solve]

These known tools are only capable of breaking up fruits or vegetables into particles or pieces of a single size and shape. Where different fruits or vegetables are processed, depending on the method used for their preparation - whether grilled, cooked or roasted, and also depending on the use of the separated ingredients, e.g. as spices, garnishes, etc. It has been found that different sizes and shapes of particles or fragments are desirable for different dishes (in most cases, garlic has a smaller size and onions a coarser particle, so traditionally two types of presses have been required). It is therefore an object of the invention to provide a manual press which avoids the disadvantages of the known tools and which allows material to be broken up into small and/or large particle sizes simultaneously and in any desired sequence. It is on offer.

[Means for solving problems]

According to the invention, this object was achieved by providing different openings in the bottom part defining different holding chambers.

In order to clean the opening in the bottom of the holding chamber, the invention has a further feature, in which at least one of the levers is provided with a group of cleaning pins, of which there may be a plurality of sets, each of which has a Corresponds to one set of apertures. In this arrangement, rotation of the lever in a direction opposite to the direction of applying pressure places the pin into the opening of the spent holding chamber.

Austrian Patent No. 294351 discloses the use of cleaning pins. However, this known tool has only one type of hole and therefore only one type of pin. If such pins were used in a manual press according to the present invention, they would be able to clean only the set of apertures for which they were intended, but not adequately clean other apertures. A pin that cannot fit or is larger than the cross section of the aperture cannot enter the aperture.

〔Example〕

Further details of the invention will be fully explained with reference to the drawings, which show several illustrative embodiments of a manual press according to the invention.

The manual press shown in the first to third figures has double-armed levers 1, 2, which are connected by a hinge 5 and each have two arms of different lengths. The long arms 1', 2' consist of handles, and the short arms 1'', 2'' are provided with a ram 3 and a screen 4, respectively. Next to the hinge 5, the handle 1' also comprises a ram 3',
This is placed on the side of the hinge opposite the ram 3 and diagonally spaced therefrom. Next to the hinge 5, the handle 2' is equipped with a sieve 4', which is on the opposite side of the sieve 4. The rams 3 and 3' each have a plunger 6 or 6' on the side facing the associated screen 4 or 4'. 2 levers 1,
2 may be detachable if desired so that it can be removed for cleaning. Each sieve 4, 4' has a bottom 7,
7'. When the press stroke is completed, the bottom 7 and the plunger 6 are in contact with each other;
The same also applies to the bottom 7' and the plunger 6'.
Walls 8, 9, 11 and 8', 9', 11' are connected to the bottom 7,
Extending from each side and end of 7', and together with a cooperating bottom 7, 7', define a chamber 12 or 12' containing the material to be treated. bottom 7,
Openings 10, 10' are formed in each of the openings 7', and these are constituted by, for example, circular holes. One bottom opening may be larger or differently shaped than the other bottom opening. At the end of the working stroke the opening 10,1
On the side remote from 0', the two rams 3,
3' are provided with pins 14, 14', respectively. When the levers 1, 2 are in the extended position shown in FIG.
Since the holes 10, 10' are entered from behind 7', any residue left in the opening through which the material passed is forced back into the holding chamber 12 or 12' and all the holes are cleaned at the same time.

The manual press mentioned above has the following working modes:
When the material to be treated is introduced into the holding chamber 12 and the two handles 1, 2 are moved toward each other in the direction of arrows A, B in FIG. It is forced through the opening or hole 10. When the levers 1, 2 are then moved into the second illustrated extended position, the pin 14 enters the opening 10, so that any residue left in the opening is forced back into the holding chamber 12. When it is desired to process the material in the holding chamber 12', the tool is rotated 180 DEG from the position shown in the third figure so that the bottom part 7' is downwards and the plunger 6' enters the holding chamber 12' from above. In other respects, the operation is carried out as described above.

If one of the side walls 8 and 9 is omitted in the screen 4 or 4' and provided on the same side in the ram 3 or 3', in the working state of the tool,
The holding chamber 12 can be cleaned more easily.
This is described in detail in Austrian Patent No. 337392. In this case, holding chamber 1
2 or 12' is open on one side, so that residues can be removed from the holding chamber with a brush or the like. In that embodiment, the holding chamber is closed during the working stroke as soon as said side wall of the ram 3 or 3' begins to overlap the bottom 7, 7' of the associated screen 4, 4'.

In the embodiment described by way of example, one holding chamber 12 is mounted on the shorter lever arm 2'' on the hinge 5.
and adjacent to the hinge. However, in this case only one holding chamber can be used at a time.

If you want to use both holding chambers at the same time,
The two embodiments described above can be modified so that the width of at least the shorter arms 1'' and 2'' of the respective levers 1, 2 is increased, for example by twice, so that the two holding chambers 12,
12' may be juxtaposed and separated by partitions. In this case, a wide ram is provided, which is divided into two parts by a slot, the width of which is slightly larger than the thickness of the partition,
These parts of the ram may each be provided with a plunger, if desired, and may enter the two holding chambers 12, 12' at the same time. Similarly in this case,
Cleaning pins 14, 14' are provided at the rear of the rams 3, 3',
Thus, in all embodiments, the thickness of the pin is matched to the dimensions of the aperture.

Another variant of the manual press according to the invention is shown in FIG.
, which are connected at one end by a hinge 5. In this embodiment, the lever 2 comprises two holding chambers 12, 12' arranged one behind the other adjacent to the hinge 5 and defined respectively by a bottom part 7, 7'. One of the bottoms has an opening or hole that is smaller or larger than the other bottom. Lever 1
are equipped with rams or plungers or the like, which respectively face the holding chambers 12, 12' and enter into the holding chambers when the two levers approach each other. On the opposite or back side of the lever 1 from the ram, plunger, etc., the lever 1 is provided with a respective set 14, 14' of pins for cleaning the openings 10, 10', respectively;
2 rotates around the hinge 5, the pin 14,
14' enters the opening in the bottom 7, 7' from the outside and forces the residue back into the holding chamber 12, 12'. Just as in the previous embodiments, the holding chambers 12, 12' may be juxtaposed. In both cases, each holding chamber 12
Alternatively, one set of outer walls 12' may be omitted and provided on other levers 1.

In some tools with one-arm levers 1, 2, as shown in FIG. 6, bottoms 7, 7' may be provided at both ends, extending over two holding chambers separated by a partition.

In this case, the openings associated with each chamber may be of different sizes. In this embodiment, the lever 1 with one or more rams 3, 3' is hinged to the top end of a frame 15, which surrounds the bottom part 7, 7' and is preferably rectangular, e.g. square. . The lever 2 supports the frame 15. The ram may be formed with a slot, which accommodates the partition 8' during the working stroke, so that each part of the ram enters a cooperating holding chamber 12, or 12'. In this example, ram 3,
3' comprises a pin 14, which enters the hole 10, 10'. Alternatively, as in the previous embodiments, the pin may be provided on the back side of the lever 1, so that it enters the holes 10, 10' from the outside.

If desired, the ram may be designed, for example, as a hinged member. Such an example is referred to as No. 10.
11. In this embodiment, the ram is hinged at 5' to the lever 1 and includes two plungers 6, 6', which are inserted into the slot 1.
The slot 16 is separated by the plunger 6,
6' enters the holding chambers 12, 12', the partition 1
Accommodates 7. When the hinges 5, 5' are properly positioned, a pin for cleaning the holes 10, 10' may be provided on the back of the lever 1.

Alternatively, a separate ram for each holding chamber 12 or 12' or a common ram for both holding chambers may be provided. In the latter case, the walls defining the holding chambers may be designed such that the ram can selectively enter each holding chamber.

In the embodiment shown in FIGS. 12 to 14, the holding chambers 12, 12' are juxtaposed and cooperate with respective plungers 6, 6'. A pin for cleaning the openings 10, 10' from the outside may be provided on the back of the lever 1. It is also within the scope of the invention to adjustably mount the plunger on the lever 1.

Figures 15 to 17 show a combination of a two-arm lever and a one-arm lever. The one-arm lever 2 comprises two juxtaposed screens 4, 4' which define holding chambers, which are separated by a partition 17. Openings 10 and 10' are formed in the bottom portions defining the holding chambers, respectively. 2-Arm lever 1
is connected to the working end of the 1-arm lever 2 by a hinge 5. 2-The arm lever 1 has two plungers 6,
6' and are separated by a slot 16 which accommodates the partition 17 when the two levers 1, 2 have completed their working stroke. The short arm 1″ has pin 1 on its outer surface.
4, 14' and two levers 1, 2.
When extended, the pins 14, 14' enter the openings 10, 10' from the outside and clean them.

In the embodiment shown in FIGS. 18 and 19, the two levers 1, 2 are one-arm, and the lever 1 has three holding chambers 12, 12' next to the hinge 5.
12'', arranged one behind the other and defined by respective bottoms 7, 7', 7''. 1 bottom 7
consists of knives 21, which in this example extend only in one direction, transversely, and the other bottom part 7 consists of knives 20', 21' extending longitudinally and transversely. The third bottom part is provided with a sieve hole 22''. A slot-like gap 22 is defined in the holding chamber 12 by a knife 21 and a square gap 22'.
is defined in the holding chamber 12' by the knives 20', 21', with which the material is processed into slices or prismatic strips, while the juice is squeezed in the holding chamber 12''. rams, plungers, etc. 3, 3', 3'', which coincide with holding chambers 12, 12', 12'', respectively. Each of said rams, plungers, etc. has a smooth outer surface or a bottom surface. 7 and 7', the plunger has a projection 2 on its other surface.
3, 23', which are shown in dotted lines in FIG. 18 and in cross section and in solid lines in FIG. The protrusions 23, 23' coincide with and coincide with the respective gaps 22, 22', so that the gaps 2
The compressed material entering 2, 22' is forced out of the gap during the working stroke.

As is clear from FIG. 19, the lever 2 is provided with a protrusion 24'' behind it, which is further away from the ram 3''. When the lever 2 is rotated about the hinge 5 in the direction indicated by arrow C in FIG. It goes without saying that a corresponding protrusion may be provided on the back for additional cleaning of the gaps 22, 22'.

In the embodiment of the manual press shown in Figure 20,
The two levers 1 and 2 have different lengths.
It has several arms. The long arms 1', 2' constitute a handle, and the short arms 1'', 2'' are each provided with a ram, plunger or the like 3 or with a holding chamber 12. Next to the hinge 5, the handle 1' has a ram,
The plunger is equipped with a 3" plunger, which is connected to the ram,
It is diagonally spaced apart from the plunger 3.
The handle 2' is provided with a holding chamber 12'' next to the hinge 5. In this example, the bottom of the holding chamber 12'' is formed with a circular hole 22'', and the bottom of the holding chamber 12 extends in the longitudinal direction. The fruit or vegetable material in the holding chamber 12 is cut into slices and the fruit or vegetable material in the holding chamber 12' is squeezed or crushed into juices. On the surface which comes into contact with the outside of the bottom 7'' when the lever 1 is rotated in the direction indicated by C, the short arm 1'' is provided with a pin 14 for cleaning the hole 22''. For the same purpose, lever arm 1' is provided with rib 2.
4 may be provided.

It goes without saying that various structural modifications may be made without departing from the scope of the invention. For example, a bottom part defining a holding chamber can be removably fitted and a bottom part equipped with knives, bars or sieve holes can be used depending on whether the fruit and vegetable material is to be broken up, crushed or squeezed. good. The choice of shape and size of the gap between the knives or bars is determined by the desired degree of crushing or breaking up of the fruit or vegetable material.
Such a bottom is shown in FIGS. 21 and 22. According to the above drawings, the knife 21 is fixed in a frame 30 and the frame 30 is connected to the bottom extension 3 of the holding chamber 12.
Place it on top of 1. The bottom portion may be removably fixed by a snap operation (not shown) so that it does not lift up from the surface 31 when the bottom portion is cleaned from the outside with a pin. If the bottom defining the holding chamber is removable, those pressure surfaces with projections that enter the openings in the bottom are likewise provided with removable inserts, so that the projections on the pressure surface of the ram are It mates with the opening in the bottom that defines the holding chamber. This precaution also applies to any projections provided on the outer surface of the lever for cleaning the apertures or holes. Such an embodiment is shown in FIG. In this embodiment, the insert consists of a plate 23, which plate has projections 24''
and in the embodiment shown in FIG. 19,
They can be slidably mounted and removed in tracks 33 provided on the back of the ram 3''.

Inserts on the bottom or pressure surface of the ram 3 may be attached in a similar manner. For example, such an insert 32' is shown in FIG. 24 and may include a knife, bar, etc. 21 and 20' and is slidably and removably mounted within a track 33'. It's fine.

The embodiment of the manual press shown in FIG. 25 is similar to the embodiment shown in FIG. 18, differing only in the arrangement of the holding chambers. For simplicity, only the lever 1 is shown in FIG. 25 as a top plan view on the holding chamber. In this embodiment, the holding chamber 12 is larger than the holding chambers 12' and 12'' and is provided with crossed knives, bars, etc. 20' or 21'. The holding chambers 12', 12'' are arranged side by side and close to the holding chamber 12, between the holding chamber 12 and the hinge 5. In this example, the holding chamber 12' has a set of small sieve holes 22'', and the holding chamber 12'' has a set of large sieve holes 22''A. The lever 2 is not shown, but is fitted A ram is provided, which may be designed like the ram of the embodiment shown in FIG. 18, but arranged like the holding chambers.

The choice of the number and arrangement of holding chambers and cooperating rams is at the discretion of the designer of the manual press. They can be left and right and/or as any desired shape and quantity.
Or they may be arranged front and back, and the handle levers 1, 2 may be one-arm or two-arm.

Alternatively, each of these two levers may have at least one holding chamber and at least one ram cooperating with the holding chamber of the other lever.

Furthermore, in embodiments having a ram, plunger or the like 3 or 3' for cutting the fruit or vegetable material into prismatic pieces or slices,
