Description

The invention relates to the implementation of kitchen appliances intended for cutting and manufacturing artistic decorative products from vegetables and fruits used to decorate the table and various dishes.

Known knife having a working element with a curved convex cutting edge and a holder with wrist rests on the lower edge (see German patent No. 3432589, CL 26 1/10, 1984). The knife is equipped with a wide durable working element (blade) and is intended for kitchen work related to cutting meat, etc., but it is not suitable for artistic cutting of vegetables and fruits due to its parameters.

A device for performing threading on flat wooden surfaces is known, equipped with several cutting tools with cutting edges of different shapes (see patent RU No. 2077429, class B 44 B 3/02, 1992). This device makes it possible to obtain complex curly elements on a processed wooden surface, but only due to the combinatorial use of different cutting tools.

The closest technical solution to the claimed invention is a figured knife, comprising a narrow curved working element having a cutting edge and fixed with a shank in a holder equipped with a carpal focus on the lower edge and a thickening on the lateral edges in the front part (see German Patent No. 19712615, C. B 26 V 3/00, 1997). The working element (blade) of this knife is formed by converging curves at an acute angle to each other, and the cutting edge is on the lower convex curve. This knife has more possibilities from the point of view of artistic cutting of vegetables and fruits than the previous ones, but it is not universal, because It is almost impossible to cut complex volumetric curvilinear elements with such a knife on fruits.

The objective of this technical solution is to expand the functionality of the set while simplifying operations on the artistic and decorative cutting of fruits and vegetables, increasing the convenience and reliability of using functional devices, reducing physical effort to perform work, increasing the speed and quality of cutting.

This object is achieved in that a figured knife for carving, including a narrow curved working element having a cutting edge and secured with a shank in a holder equipped with a carpal focus on the lower face and a thickening on the side faces in the front, is made with a working element having a convex an arcuate outer end, a stepped inner end, consisting of a rectilinear section and a rounded step element at the base, and the cutting edge is made on a rectilinear section of the inner about the end, the angle λ between the outer arcuate end and the cutting edge is selected in the range of 9 ÷ 10 g, and the ratio of the length l of the cutting edge to the width k of the working element at the junction of the cutting edge with the step element is selected in the range l / k = 5, 6 ÷ 5.8, and the holder is made of a trapezoidal section with rounded ribs, slightly expanding lateral faces to the free end, and the lower arcuate surface, and the front and free rear ends are beveled and rounded towards the lower side, and in addition, it is thicker The holder is made triangular in shape on the side faces and a trapezoidal section slightly expanding with side faces to the free end.

The invention is illustrated by drawings.

On Fig - the same, cutting out the petals. On Fig - the same, the formation of denticles on the petals. On Fig - the same, cutting the petal into several inner layers. On Fig - the same, formed a flower. On Fig is the same, the finished composition. On Fig - finished composition in the form of a bouquet of roses.

A figured knife for carving has a working element 1 made of a curly pointed elongated shape with a convex arcuate outer end 2 and a cutting edge 3 on a rectilinear portion of a stepped inner end and with a rounded element 4 at the base 5. The knife holder 6 is made trapezoidal in cross-section of the shape (Fig. 3), slightly expanding by the lateral faces 7 to the free end 8, has a rectilinear upper face 9, an arched lower face 10, rounded ribs 11, carpal rest 12 on the lower face 10 and a smooth thickening 13 of a triangular shape in the transition zone to the working element 1, merging with the carpal stop 12, as well as beveled and rounded front end 14 and rear free end 8. Moreover, the thickening 13 on the holder 6 has a trapezoidal cross section, slightly expanding lateral faces to the free end 8.

It has been experimentally established that the optimal angle λ between the end face 2 and the cutting edge 3 of the working element 1 is in the range of 9 ÷ 10 g, with the ratio of the length l of the cutting edge 3 to the width to the working element 1 at the junction of the cutting edge 3 to the rounded element 4 in range l / k = 5.6 ÷ 5.8. The forms of the working element 1 and the holder 6 are selected in such a way as to provide artistic cutting of the fruits when the knife moves in three directions: axial, radial and rotational about its axis.

Figured knife for carving is used as follows. In the manufacture of decorative ornaments from vegetables and fruits, almost all known fruits can be used. First, the blank is prepared either in the form of a truncated cone (from daikon, carrots, etc.), or a barrel-shaped form (from onions, radishes, etc.), or in the form of a curly plate (for making leaves of the future composition), or in the form of a hollow cylinder or cone, if it is a hollow vegetable, or any natural form of the fruit is used. When cutting art elements, the fruit is held with one hand, and the knife with the other. Then, the formation of grooves, grooves and other decorative elements, including the petals of the flowers made, begins in a circle in rows or in layers in height and depth, moving either to the axis or from the axis of the workpiece, while in each layer the excess cut parts of the workpiece are removed with a knife or hands.

In the manufacture of a flower like "Decorative chamomile" cut the petals along an oblique line (see Fig. 4, 5), then cut the core (Fig. 6) and get a decorative flower. In the manufacture of leaves of the future composition, a flat blank is prepared (Fig. 7), and then, using the axial, radial and rotational movement of the knife, complex curly volume cuts imitating veins are obtained on the manufactured leaves (Figs. 8, 9). In the manufacture of a composition of cucumbers with a knife, the workpiece is made with simple radial movements (Fig. 11), then the petals are prepared with oblique sections (Fig. 12), after which cloves are cut with axial and radial movements on the petals (Fig. 13). This is followed by a complex action - cutting the petals into several layers with axial radial and rotational movements (Fig.14, 15). The most beautiful flowers - roses can also be obtained using all the features of this knife (Fig.17).

The products made in the form of a variety of flowers and leaves are tinted with natural dyes from the juice of other fruits, for example, beetroot, carrot, tomato, green radish juice, etc. as needed to give them different colors and shades. Then they collect and form decorative art compositions (figures 10, 16, 17) to decorate the table or ready meals.

The figured knife for carving provides effective radial cutting by combining a convenient holder 6 with a straight cutting edge 3 of the working element 1. The thickening 13 and the palm rest 12 of the holder 6 in combination with a very sharp angle λ between the end 2 and the cutting edge 3 of the working element 1 provides an effective axial cutting. And the combination of an arcuate outer end 2 and a cutting edge 3 on a rectilinear portion of a stepped inner end, as well as the presence of a rounded element 4 at the base 5 make it possible to obtain clippings and figures of complex shape when the knife rotates. Such a carving knife allows you to quickly perform decorative art cutting of vegetables and fruits, quickly producing beautiful edible compositions that can be used in homemade food, on the festive table, as well as in cafes and restaurants.

Thus, the claimed invention solves the problem of expanding the functionality of the set while simplifying operations on the artistic and decorative cutting of vegetables and fruits, increasing the convenience and reliability of the use of functional devices, reducing physical effort to perform work, increasing the speed and quality of cutting.
