Definitions

  • the invention relates to a knife with a tang that is butt welded to one another on its flat end face with a flat face of the bolster facing away from the blade and covered by a handle body and has parallel, broad side faces.
  • a knife as is known, for example, from DE-OS 37 13 958, a knife made of flat material, e.g. stamped alder welded to the face of a goiter, the weld bead running around the end face of the alder like a collar. A sleeve-shaped handle body can be pushed onto the tang.
  • the invention has for its object to improve a generic knife manufacturing technology.
  • the object is achieved in that the bolster is only welded to a central region of the broad front edges of the alder and the handle body has grooves on the surfaces facing the weld beads.
  • a knife is provided with a stable connection between the bolster and tang, the weld connection being able to be produced in a simple manner. Since the weld beads are covered in a tunnel shape by grooves in the end faces of the handle body, they do not have to be reworked after the welding has been carried out. For a secure connection, it is sufficient if the central area of the broad side front edge welds to the bolster is. As a result of this only partial welding of the end face edge of the alder to the crop, the narrow side end edges of the alder are free of welding beads. This is particularly advantageous if the narrow side front edges are to be visible.
  • the length of the weld bead can be less than - even half - the length of the broad side front edge and still guarantee a secure connection between the tang and the bolster.
  • the handle bodies are preferably designed as two half-shells that can be riveted to the tang.
  • the outer shape of the handle half-shells can be opaque with the shape of the broad side surface of the tang.
  • the tang is then sandwiched by the half-shells, with the narrow side surfaces of the tang remaining visible.
  • the long side front edges of the alder are preferably dimensioned in length in such a way that the narrow side front edges of the alder are flush with flat edges of the goiter.
  • the end faces of the handle body facing the welding beads are designed in such a way that the end face edge of the handle body is flush with the flat face edges of the bolster, so that a continuous transition between the bolster outer surface and the outer handle surface is ensured.
  • the knife shown consists of a bolster 2 molded onto the sheet 1, the thickness of which corresponds approximately to four to five times the sheet thickness.
  • a tang 3 is butt-welded to the bolster 2 on its flat surface 2 'facing away from the leaf 1. In cross section the tang 3 has an essentially square shape.
  • the tang and goiter were adjusted so that the leaf and tang were aligned.
  • the narrow sides of leaf 1 and tang 3 are aligned, so that the narrow side end edges 9, 9 'of tang 3 are flush with the flat edges of the bolster 2.
  • the welding consists of two welding beads 4 lying opposite one another, which are arranged centrally on the broad side end edges 6 'of the tang, the length of which corresponds to less than half the broad side end edge length 6'.
  • the blade 1 and the bolster 2 can be made of a higher quality steel than the tang 3.
  • the tang 3 can, for example, be punched out of a steel sheet, while the bolster and blade can be optimally manufactured using other manufacturing methods.
  • the welding beads 4 can be applied both electrically and with a flame under a protective gas.
  • the grip body consists of two half-shells 5 which can be riveted to the tang 3, the cross-sectional contour of the two grip shells 5 corresponding to the broad side surface contour of the tang.
  • the end faces 5 'of the handle body are adapted to the flat surface 2' of the bolster 2, so that the outer surface of the bolster merges continuously into the outer surface of the handle shells.
  • the half shells are made of plastic or wood.
  • the narrow side surfaces of the alder also merge into the bolster outer surface.
  • the narrow side end edges 9, 9 'of the tang 3 are flush with the flat surface edges of the bolster 2.
  • the end faces 5 ′ of the half-shells 5 facing the welding beads 4 have grooves 7 on their side facing the tang for the tunnel-shaped covering of the welding bead section.
  • the length of the grooves 7 is longer than the length of the weld beads 4. This ensures that even with tolerances in the weld bead position or weld bead length a secure covering of the weld bead section is guaranteed without its aftertreatment.
  • the welding beads therefore do not need to be further processed after the connection between tang 3 and goiter 2 has been established.
  • the length of the weld beads is sufficient if they are less than half the length of the broad side front edge. However, it is also provided that the length of the weld beads is only slightly smaller than the length of the broad side front edge.
  • the length is preferably chosen so that the grooves 7 of the handle body 5 do not extend to the outer surface of the handle body, but are not visible when the handle body 5 is mounted. This means that the welding beads 4 should not extend to the narrow side surface 9.
