Definitions

  • the known tools for sharpening ski edges have guides sliding on the running surface of the ski and file-like elements which represent the actual tool.
  • ski edges whose edges are not disposed at right angles but at acute angles to provide a biting edge ensuring a good grip espcially on icy places.
  • the invention therefore proposes to fix a removable guide in the grip. e.g., a slidable guiding ledge whose angle towards the sharpening surface of the file plate is adjustable and which holds the file plate projecting at both sides of the guide in the grip.
  • a removable guide e.g., a slidable guiding ledge whose angle towards the sharpening surface of the file plate is adjustable and which holds the file plate projecting at both sides of the guide in the grip.
  • the file plate is inserted in a corresponding recess of the grip whereby a projection or a curved surface is provided in the grip underneath the middle of the file plate on which is set the flexible grinding plate curved to its ends by means of a guide in form of a guiding ledge.
  • the slightly curved file plate is well adapted to the camber of the ski such that it sits close to the surface of the edge.
  • a further advantageous embodiment of the invention consists in that the grip on the narrow sides of its basis comprising the file plate has extensions with oblong holes extending transversally to its longitudinal direction in which the guiding ledge may be adjusted in parallel with the sharpening surface in any position desired whereby in each position the file plate is projecting at both sides of the guiding ledge.
  • This adjustability of the guiding ledge has the advantage that the file for sharpening ski edges according to the invention can easily be conducted past the steel edge beyond the zone of the binding in particular with the guiding edge being adjusted diagonally to the longitudinal direction of the grip.
  • the guiding ledge preferably is constructed as an U- shaped profile guide open to the top.
  • one or both of the parallel running sides of the guide can be bent down to the exposed surface of the file plate to sharpen also edges which are not disposed at right angles.
  • the file plate preferably is slightly curved to the top it is advantageous that the base of the profile guide resting on it is curved according to the camber of the clamped file plate.
  • the ends of the base of the profile guide are provided with extensions which are beveled and/or half-round.
  • the straight-lined cuttings of the file plate are preferably directed such that they are extending at an angle to each other from the longitudinal median plane of the file plate. They may, however, also be disposed symmetrically curved towards their longitudinal center line.
  • FIG. 1 is a top plan view of the grip construction of the file for sharpening ski edges according to the inventlon
  • FIG. 2 is an exploded view of the grip embodying the present invention
  • FIG. 3 is perspective view of the grip when assembled
  • FIG. 4 is an exploded view of the grip of the present invention showing a modified cutting plate
  • FIG. 5 is a perspective view of the grip of FIG. 4 in assembled condition
  • FIGS. 6 and 7 show modifications of the cutting surfaces of the file plate.
  • the grip 2 preferably made of synthetic material is provided with extensions 7 on the narrow sides of its base 17, extensions in which are set oblong holes 8.
  • the base 17 is provided with a recess 4 corresponding in its extent and depth to the file plate 3 resting on it whose cutting surface or area protrudes slightly above the base 17 of the grip 2.
  • a projection 6 protruding slightly from the base 5 of the recess 4 is provided in the transversal middle portion of the grip 2.
  • the file plate 3 In setting the guiding ledge l of the file plate 3 and fixing it to the grip 2 by means of the screw bolts 9 put through the oblong holes, the file plate 3 is not only held in the grip 2 but is also slightly curved in the middle: because of the projection 6 provided underneath such that a perfect adaptation to the camber of the ski is ensured. Instead of a projection 6 a curved surface or the like may be provided in the grip underneath the file plate 3.
  • the guiding ledge is adjustable in order to use the parts of the file plate not being worn out for sharpening.
  • the parts of the device according to the invention at both sides of the guiding ledge are to be used, as the cutting surface of the file plate is projecting at both sides.
  • the surface of the guiding ledge 1 extending vertically is set on the border of the ski and drawn down the steel edge. The same process may be carried out on the other border of the ski without having to turn over the ski.
  • the guiding ledge is designed as a U- shaped profile'guide 10.
  • One or both of its parallel running sides may be bent down in direction of the file plate 3 to sharpen also ski edges with an acute angle.
  • the top edges 16 of the sides 13, 14 are beveled such that they may serve to treat the running surfaces of the ski, e.g.. to scrape off wax.
  • Both ends of the base 11 of the guiding ledge are provided with extensions 12,15, one being beveled, the other half-round. They serve to clean the grooves which usually are either beveled or half-round.
  • FIG. 6 and 7 show file plates 3 with different dispositions of the cuttings 18 extending in a fishboneshaped disposition as shown in FIG. 6 and in a curved disposition as shown in FIG. 7.
  • the removed chips are shoved towards the longitudinal middle of the ski such that in contrast to the known grinding machines for ski edges the formation of burrs is avoided which have to be cleaned off in order to maintain the qualities of the ski.
  • a hand operated device for sharpening ski edges comprising a hand gripping base member having outwardly projecting extensions at the ends thereof. a file plate having a cutting surface formed thereon positioned on said base member intermediate said extensions, an elongated guiding ledge positioned upon said file plate and extending in the longitudinal direction of said cutting surface to overlie said extensions and means provided in said extensions to facilitate the fastening of said guiding ledge thereto contemporaneous with the positioning of said guiding ledge upon said file plate.
  • a hand operated device of the type as called for in claim 1 wherein said base member is formed with a recess of a size commensurate with that of said file plate, a projection positioned in said recess and extending transversely of the longitudinal axis of said base member, said file plate being positioned in said recess and being caused to curve over said projection upon said guiding ledge being fastened to said extensions.
  • a hand operated device of the type as set forth in claim 4 wherein the sides of said channel shape guiding ledge are bent downwardly towards the cutting surface of said grinding plate.
  • a hand operated device of the type as set forth in claim 4 wherein said base is curved to conform to the curvature of the cutting surface of said file plate.
  • top edges of the side portions of said channel shape guiding ledge are defined as sharpened edges for scraping a ski surface.
