Definitions

  • the invention relates to a knife, in particular kitchen knife, according to the preamble of claims 1 and 2, respectively.
  • Knives of this type are known, for example, according to FR-A-2 153 686 and GB-A-700 062.
  • the handle is formed from two handle shells provided with side openings, the side are attached to the handle shaft of the knife blade that is configured accordingly and also provided with openings. The cavity enclosed by this is sprayed with plastic material, which also fills the openings of the handle scales.
  • the plastic handle has a longitudinal slot with which the handle is slipped over the handle shaft of the knife blade.
  • undercuts are provided at its ends, of which the free end must be bent into the undercut position.
  • the handle shaft must be heated sufficiently to allow the plastic of the handle to melt after being pushed onto the handle shaft.
  • both knife designs are rather complex and complicated, since the knife according to FR-A-2 153 686 does not suitably use plastic which has emerged from the openings if the plastic is to be injected, for the injection must remove.
  • the handle shaft With the knife according to GB-A-700 062, on the one hand, the handle shaft must be precisely tempered so that the plastic handle also melts securely, and the shaft part to be bent in at the free end also requires machining in order to adapt its outer contour to that of the plastic part.
  • the invention has for its object to improve knives of the type mentioned in that the knife handle with its essential part should consist of metal, but still one has high grip (and also slip resistance in the meantime work shelf) and this combined with the requirement of a simple manufacture and secure connection of the components to be processed, without connecting elements should appear to the outside.
  • the plastic abdominal part is advantageously located in the "access shadow" of the metal back part and, in comparison to the knife according to GB-A-700 062, is not exposed to any stresses when handling the knife, but is always against it when it is accessed Back part pressed.
  • the knife consists of the knife blade 1 with a handle attachment 2, on which the knife handle 3 of interest is arranged.
  • the knife handle 3 is formed from a metallic back part 11 and from an anchored part 12 anchored thereto, which with its flanks 13 is flush or slightly set back to the connecting edges 14 of the back part 11 connects and which is made of thermoplastic, limited elastic and non-slip plastic.
  • the knife blade 1, the handle attachment and the back part 11 are formed in one piece.
  • locking pins 15 are arranged on and under the back part 11 transversely to the longitudinal axis 10 and in the direction of the knife blade plane, which engage in corresponding locking openings 16 of the belly part 12.
  • the belly part 12 is formed from thermoplastic material and the handle 3 and latching pin 15 are made of metal, the molten connection between the belly part 12 and the latching pin 15 is achieved in the simplest manner by inductive loading or heating of the latching pin 15.
  • the latching pins 15 are provided with grooves 15 'into which the only locally heated plastic flows and thus securely latches.
  • the embodiment according to FIGS. 4 to 6 corresponds to that according to FIg. 1 to 3, but here under the back part 11, spanning the receiving recess 17 for the belly part 12, a holding web 18 with lateral holding ribs 19 is arranged, against which correspondingly grooved inner flanks 20 of the belly part 12 formed from plastic 7 are placed.
  • a mechanically stretched plastic shell forming the abdominal part 12 is shrunk onto the ribbed casting by means of heat, as indicated in FIGS. 5, 6, with an additional inductive fusion, if necessary, subsequently and additionally as a precaution explained above, can be made.
  • thermoplastic material forming the belly part 12 is a limited elastic and non-smudge-resistant plastic.
  • the plastic can be provided on its surface with a finely structured knurling 21, such as cross knurling or the like.
