Definitions

  • the present invention relates to a cleaver with a compression-forged crimp.
  • Chopping knives with a compression-forged goiter are known and are composed of a knife blade and / or a knife blade, a crop and a handle, wherein the handle is connected to the knife blade and / or a knife blade on the crop. Knives are also known in which the blade, the crop and the Erl are produced by compression forging from a single blank.
  • the FR 2 612 432 A1 describes, for example, a method for producing a multi-element cleaver in which a tang is connected to the knife blade via an upset goitre.
  • the GB 692 042 A a method for producing a knife, wherein the blank punched from a hard and stainless material in one piece is processed into a forge-forged knife.
  • the task of creating a cleaver which has better handling and Habtik and thus prevents possible injury when using the cleaver. It is another object of the invention to achieve optimal use of the blade with a good protection of the fingers.
  • the advantage of this invention is that direct contact of the finger and blade and / or blade is avoided and more comfortable handling is provided by special designs of the crop.
  • the crop covers only a part of the rear edge of the blade and / or blade surface facing the handle, and the lower region of the edge ending at the cutting edge is uncovered by the crop. This ensures that, on the one hand, the fingers are protected from the blade or the blade and, on the other hand, the blade can be used over its entire length. Even the rear blade end is sharp and usable. It is advantageous if the bottom area of the edge uncovered by the crop is in its height 1 ⁇ 2 to 5/6, in particular 2/3 of the total height of the sheet.
  • the chopping knife according to the invention can be designed such that the blade and / or leaf surface in the outline is rectangular, triangular, trapezoidal or in the form of an irregular surface, wherein the cutting edge, the Back, the erler surface and / or the erlös districten surface on the blade and / or the sheet opposite surface may have a circular arc or wavy shape.
  • the blade and / or the blade may have a constant thickness or a thickness between the back and the edge which is smaller and / or larger towards the cutting edge and / or may have inwardly or outwardly curved blade and / or leaf surfaces or two differently have shaped blade and / or leaf surfaces.
  • the blades and / or leaf surface may have a bore and / or a groove. Examples of the shapes described are cleaver, chopper, casual cleaver, Asian / Chinese chef's knife or the like.
  • the direction perpendicular to the axial direction of the cleaver, to the back of the cleaver parallel expansion of the crop at least one point is wider than the parallel to the back width of the liberated blade and / or leaf surface formed.
  • a further embodiment of the invention provides that the crop is formed in its extension to the back of the chopping knife maximally as long as the blade and / or the blade.
  • the crop is designed to cope with the pleasant handling of the cleaver by hand. An execution of the crop longer than the distance between the back and cutting would, however, the functioning of the cleaver in the way.
  • a further advantageous embodiment of the invention provides a molding on the crop, which is located on the grip side between the handle and cutting edge. This shape is a pleasant guide of the adjacent finger, and additionally provides protection of the finger from contact with any cutting material or object.
  • a recess on the handle side between handle and cutting edge there is a recess on the handle side between handle and cutting edge.
  • This recess also serves a comfortable guidance of the adjacent finger, while providing protection of the finger from contact with any cutting side existing material or object.
  • a further embodiment of the bolster according to the invention provides that the bolster is formed on its side facing the blade and / or the blade in the form of a surface complementary to the extinct blade and / or blade surface.
  • the cleaver is made of a stamped in one piece from a stainless material blank by a compression forging process. This makes it possible to reduce the work steps required for the production and is thus less expensive. In addition, the cleaver is thereby given a high stability, which increases its life. But it is also conceivable that the cleaver is composed instead of several components. The hardness and composition of the material used can vary depending on the requirement and desire.
  • a further advantageous embodiment of the invention provides that gripping elements are attached to the Erl of the cleaver. These are connected to the Erl by riveting or gluing, and may be made of plastic, ceramic or metal.
  • Fig. 1 shows a conventional chopping blade 1 in side view, which consists of the blade and / or the blade 2, the bolster 3 and the handle 4.
  • the crop 2 is a link of blade and / or blade 2 and handle 4, and has in its cross section in Fig. 2 shown shape.
  • this chopping blade 1 there may be contact of a finger with the recessed surface 5 of the blade and / or the blade 2.
  • this surface 5 does not do justice to the anatomy of the fingers, so that the chopping blade 1 has an unpleasant handling.
  • Fig. 3 shows a crop according to the invention 6, the deviating from the cross-sectional area of the blade and / or the blade 2 at a location 7 is formed wider than this. This can help prevent it from happening Use of the cleaver to unpleasant pressure points on the adjacent finger comes because the finger rests on the broader point 7.
  • FIG. 4 shows a crop 6, the grip side has a formation 9.
  • This formation 9 is used to safely guide the finger when handling the chopping blade 8, and at the same time gives a protection for the finger, which could come into contact with objects or materials located on the working side of the blade and / or the blade 2.
  • Fig. 5 shows another cleaver 8 with crop 6, in which below the handle 4, a recess 10 on the bolster 6 is present, which allows a secure guidance of a finger, which is better protected at the same time against contact with working objects or materials existing.
  • Fig. 6 shows a perspective view of another chopping blade 8, in which left and right side of the Erls 13 gripping elements 14 are attached, which are connected in this embodiment via rivets 15 with the Erl 13.
  • Fig. 7 shows a side view of a chopping knife according to the invention, in which the crop 6, the rear, the handle 4 facing edge 16 is not covered over the entire height H, but the lower portion 16a of the edge 16, which leads to the cutting edge 11 and the height h, is not covered by goiter 6.
  • the height h is equal to 1 ⁇ 2 to 5/6, in particular 2/3 of the height H.
  • the front edge 17 of the crop which lies on the side surface of the sheet 2 is inclined so that the upper end of the 19th the edge 17 is closer to the front edge 20 of the sheet 2 than the lower end 21 of the edge 17th
