Definitions

  • the invention relates to a hand-held device according to the preamble of independent claim 1.
  • ski edges should be reground regularly.
  • File-like devices are known for regrinding, but they require skill and effort, which usually cannot be assumed.
  • Skis can also be reground in the sports shop.
  • Belt sanders are used for this purpose, which sand the ski edges on the tread side. This is comparatively expensive and often a suitable sports shop cannot be reached.
  • hand-held devices which have a rotating tool, for example a grinding wheel, which is driven by a motor. Since skis are not straight on their narrow sides, but especially tailored behind the point and at the rear end, the known ones exist Handheld devices the difficulty that the ski edges in these areas can not be ground exactly, and in particular the machining depth is not uniform over the entire area of the ski edges.
  • a hand-held device has become known, for example, from EP-B 0 058 983 or CH-A 661 876. These devices also require adjustment work, which makes operation more difficult.
  • the invention has for its object to provide a handheld device of the type mentioned, which avoids the disadvantages mentioned.
  • the object is achieved by the invention according to claim 1.
  • the hand-held device has a housing 1 which is injection molded from a suitable plastic and has two switch parts 1a and 1b which are detachably connected to one another.
  • the parts 1a and 1b form an interior 1c, into which a motor shaft 3 with a bevel gear 4 projects.
  • the shaft 3 is part of an electric motor which is inserted into the housing 1 via a cover, not shown here.
  • a larger bevel gear 5 meshes with the bevel gear 4, which is also located in the intermediate space 1c and which is sprayed onto the shaft of a circumferential cutter 10.
  • the circumferential cutter 10 is mounted with two ball bearings 7 and 9 in the housing parts 1a and 1b.
  • bearing shells 6 and 8 which are preferably made of steel and are injected into parts 1a and 1b. After removing the housing part 1a, the bevel gear 5 with the circumferential cutter 10 can be removed from the housing 1 and sharpened or replaced.
  • the housing part 1b has two spaced guideways 15 and 16 which, as shown in Fig. 1, to the barrel Surface 14a of the ski 14 are created. Also used to guide the hand-held device is a button 11, which, as shown in FIG. 1, bears against the outer side 13a during the machining of a ski edge 13. The contact surface between the button 11 and the ski edge 13 forms a narrow strip and is preferably located below the position shown in FIG. 2. The button 11 is thus preferably on the inner half of the surface 13a.
  • the button 11 has a guide surface 11a which is interrupted by a part-circular recess 11c in the button 11. As can be seen in FIG. 2, the touch surface 11a or the corresponding touch edge runs in a straight line and parallel to the ski 14 applied.
  • the part-circular recess 11c has a diameter which is only slightly larger than the diameter of the circumferential cutter 10. Before and after the straight region of the tracing edge 11a, there is an area 11b which, with an increasing distance from the circumferential cutter 10, an increasing distance from the adjacent ski edge 13 having. The straight region 11a is therefore comparatively short.
  • the inclination of the area 11b to the area 11a is in the range of approximately 0 to 30 °.
  • the sides 13a of the edges 13 have an angle to the covering side 14a which is in the range between 90 ° and 60 °.
  • the circumferential cutter 10 is mounted in the housing 1 with a corresponding inclination or a correspondingly conical cutter is used.
  • the milling cutter 10 can be replaced easily and without tools.
  • a securing cam 12 is formed on the housing part 1b, which on the one hand prevents the milling cutter 10 from unintentional contact and on the other hand prevents the edges 13 from being too deeply milled by a stop on the ski 14.
  • the body 8 has a recess 8a extending over the button 11 in the longitudinal direction of the edge 11a.
  • the embodiment shown in FIGS. 3 and 4 differs in terms of the mounting of the milling cutter 10 from the embodiment described above.
  • the milling cutter 10 is mounted on the one hand in a probe body 8 'connected to the housing 1 and on the other hand in a cover 17 which is detachably connected to the probe body 8'.
  • the cover 17 has a thread 20 or another suitable connection with the probe body 8 'and can be solved for easy replacement of the milling cutter 10 with a hex key inserted into a recess 17a.
  • This bearing is characterized by a particularly precise and stable alignment of the milling cutter 10 with respect to the touch edge 11a, and the milling cutter is also particularly easy to replace.
  • the hand-held device is connected to an electrical energy source via an electrical cable 18 and can be switched on and off at a switch 19.
  • a hand-held device which is not only very user-friendly, but is also extremely reliable due to its simple and robust design because it is inexpensive and operationally reliable.
