Definitions

  • the invention relates to a tool, in particular a wrench, with a head part acting on the workpiece or the screw and a grasping serving serving to touch, weaker in the thickness compared to the head part, on the broad sides of each a support to identify the tool or Wrench is attached, which are connected to each other for attachment to the tool or wrench.
  • a tool in particular a wrench
  • a wrench which has two identifying badges on a flat handle with a protruding and circumferential edge, which are arranged on both sides of the tool, are guided laterally by the circumferential edge and are connected to one another.
  • the connection is made via two round holes in the shaft, for example by welding. Since the identification marks are provided on the badges attached to the wrench, they are of course also the introductory part of the conventional wrench marking For example, by stamping, the disadvantages indicated largely exist.
  • the object of the invention is to avoid the disadvantages of the known tool designs and in particular to find a tool quickly, e.g. a wrench of the desired size, especially in larger workshops, and thereby improve and accelerate the workflow.
  • the supports for identification are formed by a colored plastic part, which consists of a sleeve surrounding the shaft, the clear cross-section of which corresponds to the cross-section of the shaft at the location encompassed by the plastic part, preferably the color of the Plastic part is different for each tool or wrench size, but is the same for the same tool or wrench sizes.
  • a tool e.g. Wrench of a certain size is easily possible.
  • the main advantage of the tools, in particular wrenches with plastic identification in the shape according to the invention and their coloring, lies in the easy recognition.
  • the colored plastic sleeve represents an all-round identification of the tool, so that the exact size of the tool, e.g.
  • the width of the wrench in any position of the wrench and at any viewing angle are easily and clearly recognizable.
  • the colorful plastic marking gives the tools an apparently new appearance, which also makes sales easier.
  • the plastic sleeves can easily be made color-resistant, scratch and impact resistant, petrol and oil resistant, whereby the shape can be varied within wide limits.
  • the plastic part forming the sleeve has a reflective and / or fluorescent color.
  • the tools can also be used in poor lighting conditions, e.g. can be easily found or recognized using a flashlight.
  • the plastic part forming the sleeve can have a slot running lengthwise on one broad side, preferably in the middle thereof, and have an attachment on the opposite second broad side for engaging in an opening in the shaft, and the plastic part additionally Glue or weld to the shaft. Under certain production conditions, it can be advantageous for the plastic part to be cast onto the shaft.
  • the height of the plastic part is at most equal to the height of the associated head part of the tool. This avoids a hindrance when using the wrench, which could consist in the fact that the head part of the tool can only be brought up to a surface running parallel to the wrench used as far as the sleeve allows.
  • the double wrench shown in FIGS. 1 to 3 has a fork head 1 on one side of the shaft 3 and a ring head 2 on the other side.
  • the cross-sectionally double-T-shaped shaft 3 near the fork head 1 in its bending-neutral zone has an opening 4 designed as a bore, which is covered by the sleeve 5 made of plastic, for example of mechanically and chemically resistant, thermoplastic material.
  • the cuff 5 has a clear cross section 6, which corresponds to the double T-shaped cross section of the shaft 3.
  • a cylindrical extension 7 is formed on the lower broad side and passes through the opening 4 in the assembled state.
  • the sleeve 5 has a longitudinal slot 8 on its side opposite the shoulder 7, which enables the sleeve to be slipped over the shaft 3.
  • the projection 7 is pushed through the opening 4 and then additionally connected to the shaft 3 by welding or gluing.
  • the slot 8 is closed and the two end faces 9 delimiting the slot 8 then meet, as shown in FIG. 2.
  • the cuff 5 has a color assigned to the size of the fork wrench. If the ring head 2 is intended for screws of the same size, a plastic part K or a sleeve 5 in the same color can also be attached near this ring head. If the ring head 2 is intended for a different screw size than the fork head 1, a plastic part with a different color is attached in the vicinity of the ring head.
  • FIGS. 4 to 6 show a wrench with a ring head 2 and a shaft 10 with an essentially rectangular cross section, which has an opening in the form of a bore 4.
  • the cuff 11 to be mounted thereon differs from the cuff 5 only in the clear cross section 12, which corresponds to the rectangular cross section of the shaft 10.
  • the remaining same parts are provided with the same reference numerals as in FIGS. 2 and 3.
  • the part of the shaft 3 (FIGS. 1-3) enclosed by the sleeve 5 has the same height h as the fork head 1; however, it can be beneficial if the height of the cuff 5 enclosed part of the shaft 3 is slightly lower than the fork head 1.
