Definitions

  • the invention relates to a head with a mouth and mouth jaw having wrench.
  • a generic wrench is from the DE 20 2004 003 399 U1 described.
  • the head of the wrench has on a broad side the shape of an open-end wrench.
  • On the other broad side of the head has a three flanks forming angular recess for receiving a corner of a polygonal profile.
  • the diametrically opposite corner region of the polygonal profile is supported on a rounded flank of the head. This broadside allows a ratchet-like use of the wrench.
  • the US 4,889,020 describes a similar shaped spanner, in which the jaws are also designed so that the wrench can be used ratchet-like.
  • the US 6,112,625 describes an open ring spanner, which can be placed radially on a threaded shaft, in order to then be placed in the axial direction on a polygonal profile can.
  • the DE 297 08 596 U1 describes a wrench with V-shaped mutually extending toothed jaws, so that this pair of jaws can be applied to corner areas of polygonal profiles of different key widths.
  • stop balls which lie for the axial retention of the inner opening against an end face portion of the polygonal profile of the screw head.
  • a socket for plugging onto a screw head having the shape of a hexagonal profile.
  • the inner profile of this also called nut screwing tool has two superposed profile planes in the axial direction.
  • the adjacent profile plane of the opening has a twelve-fold symmetry and a total of twelve angular recesses, which correspond to the total of six hexagonal corners of the hexagonal profile of the screw head. If a screw head is inserted into the screw opening, then every second angular recess is filled with a hexagonal corner.
  • the second profile plane which lies away from the opening, has only a sixfold symmetry, namely the inner contour of a hexagon. This hexagon profile is formed by elongated angular recesses.
  • a similar jaw arrangement but on a ring spanner, describes the EP 1003 627 B1 in which, depending on the angular position of the hexagonal profile of the screw head is either in a stop position or can be inserted through the jaw opening therethrough.
  • the US 7,340,983 B2 describes a ratchet wrench with an internal polygonal profile, which consists of two adjacent in the axial direction different profile sections.
  • a first profile section has a twelve-fold symmetry.
  • Another is a six-fold symmetry, so that in a first angular position a nut abuts against stops and in a second angular position, the nut can be pushed through the key opening.
  • the invention has for its object to expand the range of applications of a generic wrench.
  • the mouth opening as an open-end wrench opening for torque-transmitting attack on the polygonal profile has two opposing mouth jaws, which extend over only one broad side over the corner regions of the multi-jaw assembly.
  • the mouth jaws are designed as parallel jaws and can be based on a hexagonal profile. But they can also be sections of a twelve-edged profile, which is offset from the multi-jaw profile.
  • the mouth opening has a width that corresponds to the key size of the hexagonal profile, ie the distance between the two parallel jaws.
  • a novel jaw-ring key is given. If the parallel jaws are used as Drehmomenteinbringzonen, the tool can be used as a known open-end wrench. However, it is also possible, the wrench in an angular position rotated by 30 ° in the axial direction on the screw head or the nut.
  • the screw head finds a radially tied up receptacle in the mouth.
  • the angular recesses are formed by a total of three flanks, with two flanks forming torque introduction zones which are at an angle of 120 ° to one another.

  • These two other jaws are also assigned Eckaussparitch locally. In this case, the torque-transmitting flanks of these corner recesses are aligned with the torque-transmitting flanks of the parallel jaws locally associated angle jaws.
  • the screw head is in a first angular position with four corner regions in a total of four angular recesses and is not only rotationally fixed, but also firmly held in the mouth in the radial direction and in an axial direction.
  • the second opposite the first rotated by 30 ° angular position are four hexagonal surfaces corresponding to them jaws, which are formed by the steel plate.
  • the connection of the steel plate to the steel base body can be positive, positive or cohesive, so in particular by gluing, welding, pinning or screwing done.
  • the connection to the steel base body is chosen such that the steel plate can be replaced.
  • the latter preferably extends in its width over half the material thickness of the steel body.

  • the nut inserted in this torque introduction zone is thus tied up in the radial direction and in the axial direction. If the nut or the screw head is inserted into the torque insertion zone equipped on the basis of an open-end wrench profile, then the key can be placed on the hexagonal profile of the screw head or the nut in the radial direction and also in the axial direction.
  • the introduction of the torque then takes place essentially over the steel plate. Since she is hardened, the key of the key does not bend.
