  "Household cutting disc".

  The invention relates to a cutting disc for a domestic appliance for cutting foodstuffs, a cutting disk which is provided with

  of a solidarity support of a disc, which presents at least one knife

  tending essentially in the radial direction, protruding from its surface

  it and disposed at an opening therein, and which, together with the support, can be placed in the domestic appliance, below a funnel thereof, and can be made integral with its drive shaft, the position of the disc bearing the knife by

  compared to the funnel being fixed in this way, and the nominal distance

  The cutting edge and the surface of the disc determine the cutting thickness of the food to be cut. A cutting disc of this kind is known from German patent application N. 28 13 168. The use of discs

  cutting of this kind brings two problems, among others. One of these problems

  my opinion is that it is often appropriate to be able to adapt the thick-

  cutter to the food to be cut. For this purpose, it has already been proposed,

  as for example in the French patent application N. 2,144,972, of

  use adjustable knives on a cutting disc or, in accordance with

  Austrian Patent Application N. 214.093, to create the possibility of

  to produce knives of different achievements in a cutting disc.

  However, we then face the other problem, which is that the

  edge of the knife, irrespective of the desired cutting thickness, must be

  always find a determined equal distance from the lower extremity

  the funnel of the domestic appliance so that the cutting operation

  flawlessly in all cases. However, if we change the

  cutting edge by giving the cutting edge another position in relation to the surface of the cutting disc, measures must be taken to ensure that the cutting edge itself takes the desired position again

  at the funnel. For this purpose, in accordance with the Austrian patent

  aforementioned dog N. 214.093, it is proposed to modify according to the knife

  if the level of the bearing surface of the cutting disk on the shaft of

  of the household handset, in relation to the surface of the housing disc.

  pe. Such a cutting disk is not simple, nor in its manufacture nor

  in his handling. Moreover, it belongs to the known technique of using

  reversible discs, as recommended by the Swiss patent application N. 552.452, aimed at solving both problems. P. this

  than the manufacture of these cutting discs.

  It should be noted here that the German patent application N0. 12 65 364 recommends a domestic handset presenting a still disc,

  attached to the shoemaker, a domestic appliance in which a single

  knife heads whose knives extend perpendicularly to the disk,

  while the disk is provided with annular portions in relief which constitute

  kill low-friction slides for food to be cut. As these annular portions in relief are oriented in the same way as the

  knives of the knife unit, the height of the annular portions does not exceed

  does not finish the cutting thickness of the food to be cut. Therefore,

  this is a disk which in totality is different from the disk of

  pe of the kind according to the invention.

  It has been very beneficial for these elevations to be

  less partially circular and that they are arranged concentrically

  compared to each other. Thus, the elevations extend in the direction of rotation of the cutting disc, so that the food introduced into the funnel of the domestic appliance always come to rest.

correctly on the elevations.

  In addition, it has been advantageous for the elevations to

  a rib shape and that they extend in the radial direction. In addition

  their, elevations of this kind can strengthen the cutting disc. Advantageously, the elevations can be spiraled. Elevations of this kind extend at least in the radial direction as well

  only in the direction of rotation of the cutting disc, so that they allow

  to obtain good support for the food to be cut and a

forcing the disc.

  It is also possible to obtain for foods

  cut a good support on the elevations of the cutting disc if the elevations

  tions are made in the form of buttons.

  In cross-section, the elevations of the cutting disc

  may have, for example, an arc shape. It has proved particularly

  advantageous in cross-section, the elevations are

  zoldales. Thus, for foods to be cut surfaces are obtained

  flat support, which guarantees particularly effective support.

  For a particularly simple realization of the elevations on the cutting disk, it has proved advantageous to form these elevations.

  by stamping in a cutting disc made of a metallic material.

  The following description with reference to the accompanying drawings,

  given as a non-limitative example, will provide a better understanding of

the invention is realized.

  C5 Figure 1 is a sectional view along the line I-I of the

  FIG. 2 shows a cutting disk with partially curved elevations.

  lar. FIG. 2 is a view from above of the cutting disc of the

figure 1.

  FIG. 3 is a view from above of a cutting disc

  sensing radially extending elevations.

  FIG. 4 represents a top view of a cutting disc

  whose elevations are spiral.

  FIG. 5 is a top view of a cutting disc

  whose elevations are made in the shape of a button.

  The cutting disk 1 shown in FIGS. 1 and 2 is constituted by a support 2 and a disc 4 carrying a knife 3. The support 2 is made here in the form of a sleeve and has an internal lug 5. This support 2 makes it possible to insert the cutting disc 1 into the household handset

  and to couple it to its drive shaft, the lug 5 of the support 2 engages

  gating in a corresponding groove of the drive shaft,

  that the cutting disc can be entranced in the rotational movement of this tree. It goes without saying that the coupling coupling can be achieved in another way, a goal in which there exists, as known, a

many possibilities.

  In the embodiment envisaged, the disc 4 carries a single knife 3 extending essentially in the radial direction, projecting from the surface 6 of the disc 4 and disposed at an opening 7

  practiced in the disc, a knife which, for example, can be attached to the disc

  The cutting edge of the knife 3 is indicated by the reference 9. For the reinforcement of the disc 4, the latter has on its periphery a folded edge 10, which is directed in an opposite direction.

with protruding knife 3.

  To enable the disc 4 to be connected to the support 2, the disc 4 has a central opening having a folded edge 11. In this way, the disc 4 can be mounted on the support 2 while, on the one hand, it is supported on a face 12 of the support 2 and, secondly, it is centered -5-

  by its folded edge 11 on corresponding bearing surfaces 13 of the sup-

  port 2. In the embodiment envisaged, to join the disk 4 and the support 2 safely, there is further provided a holding piece 14 in the form of a pot which, after the introduction of the disk 4 on the support 2

  placed on the assembly and pressed onto the support 2, so that the

  port 2, the disk 4 and the holding part 14 constitute a building unit. If the support 2 and the holding part 4 are made of plastic, their assembly and their association with the disc 4 can be done, for example, by ultrasonic welding. However, in the case

  of a support 2 of plastic material, the disc 4 can be embedded directly

  by molding in the support 2 and thus be made integral with this

  him one. It goes without saying that the connection of the disc 4 to the support 2 must resist

  to torsion to ensure that the disc 4 is driven, which can

  be obtained for example and in a current way by the nesting of sec-

  discs 4 on the one hand and the support 2 or the holding part 14 on the other hand. For this purpose, it is also possible to

  their shape the central disc opening 4 surrounded by the edge 11 and the sur-

  supporting surfaces 13 of support 2 cooperating with this edge 11, so that, as a result, a torsion resistance is obtained. Measures of this kind are not explained in detail in this paper because

  they are not important in the context of the invention.

  When setting up the cutting disc 1 in the domestic appliance, the support 2 secured to the disc 4 bears in the axial direction either on the free end of the drive shaft of the handset, or on a collecting container. placed in the usual way on the handset, so

  that a level is set at which the disc 4 rotates as soon as it is actuated.

  Then, after inserting the cutting disc, one poses further, also

  In a conventional manner, the collecting vessel of the handset is provided with a funnel-loaded lid into which food to be cut is introduced. and funnel extends by its inner edge, which is located on the side of the cutting disc, at a determined distance from the cutting disc and, therefore, the cutting edge 9 of the knife 3 mounted on the disc 4. This distance between the cutting edge 9 and the lower edge of the funnel

  must have a predetermined value which is not too great, to ensure

  than the cutting of food introduced into the loading funnel

  It is carried out in a clean and perfect manner.

  The funnel, because the cutting discs are distinguished from each other only by the elevations. Moreover, this makes it possible to manufacture cutting discs of this kind in a very simple and inexpensive way, because

  can use the same tools up to the elevation training stage.

  In the embodiment considered, the elevations 15 of the disc 4 are partially circular and are concentrically arranged relative to one another. Thus, the elevations 15 extend in the direction of rotation of the disc, which ensures that the food to be cut

  always come to rest in an impeccable manner on the elevations 15.

  As can be seen from FIG. 1, in the embodiment considered, the elevations 15 have a trapezoidal cross-section, so that flat bearing surfaces are obtained for the foods to be cut, which also promotes good support. of these foods and, therefore, a flawless cutting operation. Effectively, the elevations 15 are

  formed in a disc 4 made of a metallic material, preferably

  This is a chrome steel for deep drawing, which significantly simplifies the manufacture of the disc. Obviously, it is also possible that such a disc 4 is made of another material, such as for example a plastic material reinforced with glass fibers. Where appropriate,

  a disk 4, as described above, can be provided further with

  additional configurations having a rib shape and extending into the

  radial direction, ribs which are then provided between the partial elevations

  15. Such radially extending elevations increase the rigidity of the disc 4 and at the same time enlarge the bearing surfaces for the foods to be cut. If it is only necessary to increase the rigidity of the disk 4, it is also possible to add additional radial elevations which are directed opposite the elevations 15, additional elevations which, then, do not act

  elevations according to the invention. If we give up the use of

  additional radial elevations, the elevations 15 may be entirely

  circular and not partially circular. As is apparent from the

  FIG. 2, the elevations 15 close to the opening 7 practiced in the

  4 extends to the edge of the opening 7, so that the foods to be cut resting on these elevations are maintained at the desired distance from the cutting edge 9, distance determining the cutting thickness,

  so that the cutting operation is carried out precisely.

  In the embodiment of FIG. 3, the disc 4 carries

  8 as the knife 3 is provided with separate elevations 19 on its surface 6 is

  finding on the side of the cutting edge 9, elevations which are realized exclusively

  rib-shaped and arranged in the radial-free. These elevations 19 again fix a tangential plane on the disk 4, plane

  whose nominal distance from cutting edge 9 determines the thickness

  cutter. These radial elevations 19 give a very high stiffness

  4. As these elevations 19, seen in the direction of rotation

  4, are arranged at a small distance from each other, we ob-

  Here, too, there is impeccable support for foods to be cut.

  In the embodiment of FIG. 4, the surface 6 of

  disc 4 on the side of the cutting edge 9 is provided with separate elevations

  having a spiral shape. In this way, the elevations extend

  tooth in a sense which, in a way, corresponds both to the sense of rota-

  tion of the disk in the radial direction, so that these elevations allow to obtain good support surfaces for the food to be cut and a reinforcement of the disk 4. Where appropriate, it is possible to provide even more elevations of more small dimensions on the disk a, namely in the

  areas between elevations 20. In addition, it is possible to

  at the elevations a widening cross-section towards

  around the disc or superimpose a corrugated shape

elevations.

  In the embodiment of FIG. 5, the disc of

  pe 1 is provided with six knives 21 which, two by two, present a displacement

  radial as well as angularly relative to each other. These knives 21 are constituted by tabs which have been taken out of the plane of the disc 4 and which have a cutting edge 9 at their free end. In

  these conditions each of these knives 21 is at the level of an opening.

  22 in the disk 4. In the embodiment considered, the elevations 23 provided for fixing the thickness of the cut are

  made in the form of buttons. In this case, the elevations 23 are distributed

  almost uniformly on the total surface 6 of the disc 4, in any configuration. In this way, these elevations constitute a

  impeccable support surface for food to be cut and fix again

  a tangential plane on disk 4, plane whose nominal distance

  relative to the cutting edges 9 determines the cutting thickness. The realization

  such a cutting disc is also very simple.

  Obviously, one skilled in the art can imagine many

  its other variants of the embodiments described above without

  however, within the scope of the invention. This applies in particular to the

  me elevations and their distribution on the surface of the disc. In any case, it is essential that the discs themselves and their supports are all made in the same way, so as to ensure that, for all cutting discs that can be placed in the domestic appliance, the distance

  between the cutting edges and the bottom edge of the funnel be equal.
