Definitions

  • the subject of the present invention is a device for processing or finishing the blades of a ski, a snowboard or the like.
  • the present invention relates to a device adapted for finishing the side surface and the sliding surface of both blades of a ski by a grinding wheel.
  • a device for processing the blades of a ski fitted on a machine adapted for receiving the ski and automatically carrying out the blade finishing operation. More precisely, there are provided two devices for processing the ski blades, arranged at opposed sides with respect to the longitudinal ski development. The ski is inserted into a seat of the machine and, by moving the ski itself along its longitudinal axis or moving the above devices along a direction parallel to the longitudinal ski axis, a relative translation motion is obtained between the ski and the devices in question, which allows processing the entire blade length.
  • the ski shape has brought to favour the so-called shaped skis, that is, wherein the width in the direction perpendicular to the longitudinal ski length varies along the longitudinal development itself.
  • the ski exhibits enlarged portions at the tip and at the tail whereas the central portion of the ski exhibits a smaller width. Consequently, the side blade surface exhibits a curvilinear outline relative to the longitudinal ski axis, which known devices are not always capable of finishing. Consequently, the ski is not capable of ensuring optimum performance in terms of speed and blade grip of the snow mantle, for example icy.
  • the known devices are easily stuck along the side blade surface, thereby creating an inaccurate finishing with consequent reduced performance during the use of the skis, especially during competitions.

  • feeler pin 96 is arranged at an inside portion of the cup grinding wheel 60, so that the abrasive ring 60a of the cup grinding wheel exhibits an outside edge 60b substantially at the edge 100 delimiting the sliding surface 14a of the blade and the sliding surface 12a of the ski ( figure 20 ) or in any case comprised between the delimiting edge 100 and the lower outside edge 15a of the blade.
  • the feeler pin defines a means for limiting the processing area of the grinding wheel so that, especially in the case of a ski with lowered blade as shown in figure 3b , it is possible to process the blade without involving the base.
  • arm 98 that supports the feeler pin 96 is made of two parts.
  • a first part 98a is fastened to upright 67 of the support element S, for example by threaded connections, and it exhibits a fork shape.
  • a second part 98b is fitted on the first part 98a by a pin 99a and on a threaded element 99b to adjust its position relative to the grinding wheel abrasive ring.

  • thickness s of the abrasive ring of the second grinding wheel 60 is smaller than width 1 of the sliding surface 14a of the blade, thereby allowing an even easier processing of lowered blades as illustrated for example in figure 3b ( figure 20 ).
  • the presence of feeler pin 96 and the provision of a grinding wheel with thickness s smaller than width 1 of the blade contribute to limiting the grinding wheel processing only to the blade without interfering with the base in case of conventional skis and allowing optimum blade processing in case of skis with lowered blade, without any interference with step 16.
  • the support element S with reference to the second portion 10b of device 10 is schematised in figures 10 6a-6c to schematically show the operation of device 10 as described below.
  • the ski is arranged on the machine seating two devices 10 arranged specularly at opposed sides of the ski relative to axis X-X for processing the two blades at the same time. Based on the type of machine, the ski or the devices 10 are moved along a direction X-X so as to create a relative motion between the ski and the devices themselves to process the blade along its entire extension.
  • the front carriage 24 and the rear carriage 50 move from a rest position ( figure 4a ) to a sided position ( figure 4b ) wherein the feeler pins 56 come into contact with the side surface of the ski.
  • the feeler pins 56 follow the curvilinear outline of the side ski surface due to the variation of width L along axis X-X ( figures 4b-4c ).
  • the rear carriage 50 and therefore also the front carriage 24 oscillate around axis c-c in a substantially horizontal plane.
  • the front carriage 24 is made to move forward relative to the rear carriage 50 by the actuator 52 ( figure 4d ).
  • the further actuator 53 ensures constant contact between the feeler pins 56 and the side ski surface.
  • the inclination of axis a-a of the first grinding wheel 18 is changed by screwing the threaded member 36 by the flywheel or preferably by motor 44b suitably controlled and with feedback to follow the inclination of the side surface of the blade during the ski processing ( figures 11-14 ).
  • arm 34 is raised or lowered and consequently motor 20 rotates, sliding on pins 32.
  • the advantageous provision of an arched slot sliding on pins, substantially acting as a cam allows setting such an axis of rotation b-b of the grinding wheel as to abut on the lower outside edge 15a of the blade, that is, on the intersection of the two useful surfaces of the blade.
  • Such movement of the grinding wheel axis allows adjusting the grinding wheel angle during processing, keeping the grinding wheel in contact with the ski.
  • the fulcrum is kept on the outside corner of the blade and the grinding wheel rotates, optionally suitably controlled, during the relative motion between the ski and device 10 to optionally generate different inclinations of the blade between the tail portion, the central one and the tip portion of the ski.
  • figure 6a-6c schematically shows the support element S in come processing stages. From a rest condition ( figure 6a ), the support element is moved along the direction Y-Y close to the ski to be processed. The position of the grinding wheel along direction Z-Z is defined by actuator 70 and the sliding of carriage 66 along guide 68 of the support element S. The support element S therefore moves forward along direction Y-Y until the feeler pin 96 comes into contact with the side ski surface ( figure 6b ). Carriage 66 is therefore raised along guide 68, moving the second grinding wheel 60 in contact with the sliding surface of the blade ( figure 6c ).
  • the inclination of the second grinding wheel 60 is carried out by screwing or unscrewing the threaded member 80 by the flywheel or more preferably by the controlled command of the motor defining the actuating portion 90b.
  • the advantageous provision of an arched slot sliding on pins, substantially adapted for acting as a cam allows setting such an axis of rotation b'-b' of the grinding wheel substantially coinciding with the lower outside edge 15a of the blade, that is, with the intersection between the two useful surfaces of the blade.
  • Such movement of the grinding wheel axis allows adjusting the grinding wheel angle during processing, keeping the grinding wheel in contact with the ski.
  • the fulcrum is kept on the outside corner of the blade and the grinding ewheel rotates, optionally suitably controlled, during the relative motion between the ski and device 10 to optionally generate different inclinations of the blade between the tail portion, the central one and the tip portion of the ski.
  • a device for processing the blades of a ski allows processing also curvilinear side surfaces carefully as in the case of skis whose width varies along the longitudinal ski development.
  • the oscillation around the vertical axis c-c of the motor is generated and controlled by the feeler pins themselves kept in constant contact with the ski blade, thanks to the actuator 53.
  • the advantageous provision of two carriages, one adapted for supporting the motor and the other adapted for supporting the feeler pins, allows moving the two carriages relatively, dividing the step of siding and positioning the device on the ski from the step of beginning of the processing or finishing with the grinding wheel moving close to the blade.
  • the provision of a movement of adjustment of the inclination of the grinding wheel axis allows choosing the best inclination of the surface of the blade to be processed.
  • the original provision of realising such adjustment movement by a controlled motor with feedback optionally along with the provision of controlling the movement axis of the ski relative to the device or vice versa, allows obtaining the correct inclination of the blade along the entire development axis of the ski X-X.
  • the two portions 10a and 10b can also be provided independently from one another.
  • the means for changing the inclination of the axis of rotation of the grinding wheel can be applied to any type of grinding wheel adapted for processing a surface of a ski blade.
