Definitions

  • the invention relates to a tool with which adhesive residues, Films, covers or the like of documents, in particular Metal surfaces can be removed.
  • Such a tool is already known (US-PS 5259914), where a tool shank with a flat metal disc is screwed.
  • the disc has circumferential notches and is in a flat one made of a soft plastic Disc embedded.
  • the notches are required for the soft plastic is taken with the rotary drive.
  • the metallic disc is on all sides of the soft plastic surround. The tool is clamped in a rotary drive and used so that the outer surface of the soft rubber washer pressed against the surface with the material to be removed becomes. It heats up and thereby detaches of the material. The rubber washer wears out.
  • the invention has for its object a tool to create the type mentioned above, which is easier to manufacture leaves.
  • the invention proposes a tool with the features mentioned in protection claim 1. Training the invention are the subject of dependent claims.
  • the tool according to the invention has the advantage that none Embedding a metallic part in the flat pane more must be done. Therefore, when using the Tool wearing rubber washer manufactured separately and then connected to the shaft and the clamping device become. After wear, the rubber washer can also be replaced respectively.
  • the disk has a central, continuous from one flat side to the other flat side Has opening through which the clamping means is connectable to the shaft.
  • This central opening can manufactured in a very simple manner in the manufacture of the disc become.
  • the rotation between the shaft and the disc can happen, for example, that the clamping means firmly against the shaft with the intermediate part of the middle Disc is clamped.
  • the shaft and the clamping device with the flat sides of the Glue the pane in the central area can happen, for example, that the shaft and the clamping device with the flat sides of the Glue the pane in the central area.
  • the invention proposes that Form the opening of the disc so that it is circular deviates.
  • the opening part of the clamping means reaching through the disc and / or of the shaft deviates from the circular shape, in particular one the opening of the disc can have a corresponding shape.
  • the tool turns in the direction of rotation Form fit between the shaft and the clamping device on the one hand and the soft disk on the other hand. This leads to for an improved driving of the disc with the rotary drive.
  • the shaft is perpendicular to its axis of rotation Has contact surface against which the disc braced becomes. This contact area increases the contact areas between the shaft and the soft disc what transmission of the torque when driving is also improved.
  • the clamping device is perpendicular to the axis of rotation of the tool has running contact surface against which the disc braces.
  • the clamping means a Has spring washer, one side of which forms the contact surface. The soft disc is then between the two contact surfaces clamped.
  • the tensioning disk can be screwed to the shaft become.
  • the Screw is integrally formed on the tensioning washer, in other words, a screw with a radial one Respect very large head is used.
  • the opening of the disc and / or through part of the clamping means reaching through the opening and / or the shaft has the shape of an impeller or a multi-jet Have a star.
  • Figure 1 shows a view of the tool in which the soft rubber existing disc is cut.
  • the tool contains a shaft 1, which on its one in Fig. 1st lower free end of a smooth cylindrical shaft portion 2 has.
  • Shank 1 of the tool used in a drive device be, for example, a drill or a screwdriver.
  • a flat-tapered disc 3 On the smooth cylindrical shaft section 2 is followed by a flat-tapered disc 3, which on the side 4 facing away from section 2 is flat.
  • On the flat flat side 4 closes a section 5 of the Shaft 1, which has the shape of an impeller with three blades having.
  • This section 5 of the tool shank 1 engages through an equally shaped opening 6 made of soft rubber existing disc 7 through.
  • the disc 7 is with her a flat side 8 on the flat flat side 4 of the flat-cone Disc 3 on.
  • a clamping means 9 screwed, which is a flat, in particular contains metallic disc 10.
  • the metallic disc 10 contains a central hole through which a screw 11 reaches through.
  • the screw 11 is in a central threaded hole 12 of the shaft 1 screwed.
  • Figure 2 shows in cross section through the tool of the figure 1 the shape of section 5 of the tool shank with the three Wings 13 of the section in the form of an impeller 5 of the tool shank.
  • the opening 6 has the same Form on so that section 5 with its three wings 13 in the corresponding radially extending parts of the opening 6 engages the disc 7. This is a great way given the taking of the disc 7.
  • FIG. 3 shows the tool shank 1 from the same direction as in Figure 1. Two of the wings 13 can be seen on the right and left, while the third wing is shown in the front view.
  • the screw 11, in the example shown a countersunk screw, is through the central opening of the spring washer 10th inserted and into the threaded hole in the axis of rotation 12 screwed in.
  • FIG. 4 shows a top view of the tool shank, in Figure 3 from above.
  • the wings 13 of the section 5 arranged on the tool shank. It goes without saying also possible section 5 with wings 13 form on the clamping means 9 and then this with the Screw disc 3 of tool shank 1. Likewise it is possible that the core 13 having the wing 13 Shaft 1 is not hollow, but one with an external thread provided provided pin-like end, which then in the central threaded opening of the tension washer 10 is screwed in.
  • the tool shank 1 and the clamping means 9 are shown in the Example referred to as consisting of metal. It here, of course, a plastic comes into question, where it however, it would have to be a plastic that is relative is hard so the transmission of the torque from the drive device can be done.
