Definitions

  • the invention relates to a marking device for the mounting of ski bindings, more especially rotary plates of safety ski bindings.
  • a heel-tensioning member acting on the heel of the boot is provided with practically all ski bindings.
  • This heel-tensioning member can either be a cable tensioning device or, for particularly high stands, for example for racing purposes, it can be a long strap.
  • a safety ski binding In order to permit the ski boot to swing outwardly with a heavy fall, it is also necessary with a safety ski binding to have a plate mounted for turning movement on the ski, a socalled rotary plate, in addition to the safety cheek engaging on the toe of the boot, the long strap and/ or also a heel-tensioning spring.
  • Such rotary plates are usually fixed on the ski by three or four screws.
  • the mounting of the rotary plate takes a comparatively long time, since not only do the screw holes have to be drilled at an accurate spacing from one another, but it is also important to ensure during the mounting operation that none of the screw holes is disposed above the guide groove of the ski, i.e. along the centre line, since otherwise there is a danger of one of the long fixing screws projecting in the guide groove on the underside of the ski.
  • the object of the invention is to provide a marking device or jig for the mounting of ski bindings, more especially rotary plates of safety ski bindings, which device substantially shortens the marking operation.
  • the marking device or jig according to the invention is characterised by a rectangular base plate which is approximately as wide as a ski, a punch plate mounted for displacement vertically in the said base plate and provided on its underside with centre punches, the number and arrangement of which correspond to those of the screw holes required for mounting the rotary plate, one or more openings provided in the base plate for the passage of the centre punches and a securing means which secures the punch plate against lifting.
  • the new marking device is placed on the ski at the place where subsequently the rotary plate is to be fixed.
  • the downwardly projecting centre punches which are identical in position with the screw holes of the rotary plate, make a mark on the ski surface.
  • the centre punches are so arranged on the punch plate that during the marking operation no centre punch, and consequently during the assembly no screw hole, is located above the guide groove of the ski.
  • FIG. 1 is a plan view of a rotary plate of a safety ski binding
  • FIG. 2 is a side elevation of a ski with the mounted safety ski cheek plate and the new marking device, which is pushed under the heel of the ski boot,
  • FIG. 3 shows a constructional form of the new marking device
  • FIG. 4 shows another embodiment of the new marking device on a left ski
  • FIG. 5 shows the same marking device as in FIG. 4 on a right ski
  • FIG. 6 is a section through the marking device on the line VIVI of FIG. 5.
  • the reference 1 indicates the rotary plate of a safety ski binding, which is fixed with three screws 2 to a ski 3.
  • Fixed on the ring 4 of the lateral cheek plate 5 is a tightening spring 6, in which engages a tightening device 7 which in its turn is connected to the long strap 8.
  • the long strap 8 is wrapped in known manner several times around the boot and is drawn through the rings 4 and 4a, the end of the strap 8 being fixed in a clip device (not shown).
  • the tightening spring 6 instead of the boot being secured by means of a long strap, it is also possible to provide the tightening spring 6 only, in which case one end of the tightening element 7 can be fixed directly on the ring .a or on a second tightening spring.
  • the long strap it is also possible to provide a simple catch strap, which has the object of securing the ski on the boot when the safety binding has been opened.
  • Three holes for the screws 2 are necessary for mounting the rotary plate and these three holes can be marked by means of the new marking device or jig, as shown in FIG.
  • the new marking device consists of a base plate 9 in which is preferably provided a relatively large round opening 10. At the rim of this opening, the base plate 9 comprises an annular recess 11 in which a punch plate 12 is arranged so as to be axially movable.
  • the punch plate 12 comprises on its underside three centre punches 13, the number and arrangement of which corresponds to those of the three screw holes necessary for the screws 2 of the rotary plate.
  • the centre punches 13 are so arranged on the punch plate 12 that none of the punches is disposed on the longitudinal centre line of the ski.
  • a boss 16 is also arranged in the centre of the punch plate 12 and for the passage of this boss, the cover plate 14 is formed with an opening 17 Furthermore, the punch plate 12 carries at one point a lever 18 which is guided in a recess 19 of the cover plate 14 and thus secures the punch plate 12 against turning.
  • the boot 21 is moved up to the said plate. Thereafter, the new marking device is pushed under the heel of the boot, as shown in FIG. 2, so that it is positioned at the place where subsequently the rotary plate is to be mounted. Since the base plate 9 is rectangular and it is approximately as wide as the ski, it can easily be so arranged that its longitudinal edges extend parallel to the lateral flanks of the ski.
  • the boot is now carefully lifted olf the ski so that the marking device is not moved. By tapping with a hammer on the boss 16 of the marking device, the punch plate 12 is forced downwardly so that the centre punches 13 make a mark on the surface of the ski. Thereafter, the marking device is lifted olf, so that the necessary screw holes can be drilled according to the marks made by the centre punches.
  • FIGS. 4 and 5 show a particularly advantageous embodiment of the new marking device. It has been found in practice that the centre line of the rotary plate should not coincide exactly with the longitudinal centre line of the ski. Thus, with a left ski, the centre line of the rotary plate must be moved to the left by a distance a (4 to 5 millimetres) in relation to the longitudinal centre line of the ski. Similarly, the longitudinal centre line of the rotary plate on a right ski is displaced to the right relatively to the longitudinal centre line of the ski. It has moreover beenfound that the outer edge 3a of the ski 3 is subjected to heavier loads than the inner edge 3b.
  • the marking device of the constructional example shown in FIGS. 4 and 5 is so arranged that the punch plate 12 is not only movable axially but is also mounted to swivel through 30.
  • -th e cover plate 14 comprises a Wide recess 19a.
  • the marking device is displaced to the left by the distance a (for example 4 to 5 mm.) with a left ski, corresponding to the required position of the rotary plate.
  • the longitudinal centre line of the ski takes up a position exactly in the middle between the two centre punches 13a and 13b.
  • the guide groove of the ski which is shown by the dotted line 22 in FIGS.
  • the new marking device is again shown in FIG. 5, but in this case, since it is a question of a right ski, the marking device is moved by the distance a towards the right.
  • the lever 1% is also swung to the right, so that now the two centre punches 13a and 13b are disposed to the right of the longitudinal centre line of the ski, so as to conform to the requirements set forth above.
  • the new marking device is not only suitable for marking the screw holes for the rotary plate shown in FIG. 1 of the drawing, but it is quite possible also to use the new marking device for other ski bindings if the centre punches are arranged on the punch plate so as to correspond to the arrangement of the screw holes required for the said ski bindings.
  • the marking device according to the invention has the advantage that it is freely displaceable when being aligned on the ski according to FIG. 2. Since the punch plate is displaceable vertically in the base plate, the punch plate is raised when placing the marking device on the ski, so that the centre punches do not project beyond the base plate, that is to say, the said centre punches do not interfere with the free movement of the base plate on the ski.
  • a marking device for marking on the upper surface of a ski the positions of screw holes intended for securing a ski binding plate onto the ski, the combination comprising:
  • a rectangular base plate having substantially the same width as a ski and having means on its lower surface adapted to rest on the upper surface of a ski, said base plate having a central opening therethrough 4 extending transverse to said lower surface, said central opening being relatively large and round and having an annular recess at its upper end;
  • a punch plate mounted in said central opening for axial movement therein in a direction transverse to said lower surface of said'base plate, said punch plate having on its lower side three prick punches spaced apart from each other by an angle of degrees, said punch plate having a flange at its upper end which flange is received in and is axially displaceable with respect to said recess;
  • abutment means for limiting downward movement punches project below the plane of the lower surface of said base plate
  • a marking device for marking on the upper surface of a ski the positions of screw holes intended for securing a ski binding plate onto the ski, the combination comprising:
  • a rectangular base plate having means on its lower surfaceladapted to rest on the upper surface of a ski, said base plate having a central opening therethrough extending transverse to said lower surface;
  • a punch plate mounted in said central opening for axial movement therein in a direction transverse to said lower surface, said punch plate having a plurality of prick punches on its lower side corresponding in number and arrangement to the screw holes to be marked;
  • abutment means on said, base plate for limiting axial movement of said punch plate in said opening, the abutment means for limiting downward movement of said punch plate being so arranged that in the lowermost position of said punch plate said prick punches project below the plane of the lower surface of said base plate;
