Definitions

  • the invention relates to a knife, in particular a kitchen knife, consisting of the knife blade with a handle attachment on which the knife handle is arranged.
  • Knives of the type mentioned are generally known and in use, so that no special printed evidence is required in this regard.
  • the knife handle is usually formed from two laterally attached handle pieces (wood, plastic, metal), which are connected in a suitable manner to the knife or its handle attachment.
  • Laterally attached wooden or plastic handles leave something to be desired sooner or later due to the constant flushing load in their tight fit to the handle attachment.
  • Grips made of metal retain their fixed assignment to the handle attachment, but they are hard and cannot be grasped securely, even with surface structuring, and are also not non-slip, which is also the case for handles made of wood or plastic.
  • the innovation is based on the task of improving knives of the type mentioned in such a way that the knife handle with its essential part should be made of metal, but nevertheless has a high degree of grip (and also slip resistance with an interim work shelf) and this combined with the requirement of the simplest possible Manufacture and secure connection of the components to be processed without connecting elements appearing to the outside.
  • the entire handle or the essential part of the handle (second solution) consists of metal, but the co-processed plastic, without being provided in the form of two-sided jaws, for access and slip resistance worries.
  • the plastic advantageously takes over the connection function between the metallic handle and the handle of the knife blade, and in the second case there are no connecting elements such as rivets, screws or the like that appear to the outside, which also applies to the first solution .
  • the knife consists of the knife blade 1 with a handle attachment 2, on which the knife handle 3 of interest here is arranged.
  • the knife handle 3 is formed from a metallic hollow body 4 with at least one opening 5 in each handle flank and in the cavity and in the openings 5 the plastic handle 7 surrounding the handle attachment 3 is arranged, which consists of the openings 5 protrudes beyond the grip flank surface 6, forming knobs 7 '.
  • the preferred embodiment is shown, in which the openings 5 are arranged in the form of inclined slots 5 ′ in two longitudinal rows 9 in the grip flank surfaces 6.
  • the plastic 7 forms an intimate bond with the metal parts, but as a precaution, at least one latching cut 2 ′ or one latching opening 2 ′′ can be arranged in the handle attachment 2 of the knife blade 1.
  • the plastic 7 advantageously protrudes from the openings 5 by only 0.5 to 2 mm and is provided with rounded peripheral edges 8. On the one hand this results in a good grip, on the other hand there are no cleaning difficulties. Liability on the work surface when stored is also improved. Also in the sense of good grip, the slots 5 'are arranged inclined with respect to the longitudinal axis 10 of the knife.
  • Fig. 2-4 The above-mentioned double function of the plastic is clear from Fig. 2-4 and also the design of the handle 3 in the form of a hollow body 4, which consists of either two pressed and appropriately pre-punched stainless steel sheet or investment casting shells 4 ', which before assembly and combination with the plastic, for example, by welding to form the hollow body 4 according to FIG. 3, which is then introduced with the knife blade 1 into a suitable injection mold 22 and, as shown, fully sprayed out.
  • a hollow body 4 which consists of either two pressed and appropriately pre-punched stainless steel sheet or investment casting shells 4 ', which before assembly and combination with the plastic, for example, by welding to form the hollow body 4 according to FIG. 3, which is then introduced with the knife blade 1 into a suitable injection mold 22 and, as shown, fully sprayed out.
  • the knife handle 3 is formed from a metallic back part 11 and from an anchored part 12 of the belly which is flush or slightly set back with its flanks 13 to the connecting edges 14 of the back part 11 connects and which is made of thermoplastic material. Both Embodiments according to FIGS. 5 and 8, 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 way 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.
  • FIGS. 8-10 corresponds to that according to FIGS. 5-7, but here a retaining web 18 with lateral holding ribs 19 is arranged under the back part 11, spanning the receiving recess 17 for the belly part 12, to the correspondingly grooved part Inner flanks 20 of the belly part 12 formed from plastic 7 are created.
  • a mechanically stretched plastic shell forming the belly part 12 is shrunk onto the ribbed cast part by means of heat, as indicated in FIGS. 9, 10, with an additional inductive fusion as follows, if necessary, additionally and as a precaution explained above, can be made.
  • thermoplastic 7 forming the knobs 7 'or the belly part 12 is a limited elastic and non-slip plastic 7.
  • the plastic 7 can be provided on its surface with a finely structured knurling 21, such as cross knurling or the like.
  • the openings 5 in the embodiment according to FIG. 1 are, as described and illustrated above, preferably in the form of slits arranged at an incline.
  • it can also be a matter of a plurality of circular punched-outs or holes or slots which are oriented parallel to the longitudinal axis of the knife and extend over the entire length of the handle.
  • the slots can also be oriented vertically to the longitudinal axis, and it can also be at least one continuous slot which extends essentially over the entire length of the handle.
