Definitions
- the invention relates to a portable device for sharpening the edges of a ski, each edge having a lower face bordering the flat of the ski and a side face bordering its edge, device comprising a frame having: - first means of support in a lateral direction and intended to be applied against the edge, and second support means in a transverse direction and intended to be applied against the flat, - and fixing means of a machining assembly comprising a abrasive tool by rotation and an abrasive tool driving motor, said fixing means allowing a translation of the machining assembly in a first direction of adjustment included in the lateral-transverse plane and coinciding with the axis of rotation of the abrasive tool.
- a square is a suitable steel rod that borders the sole of a ski or any other means of gliding on snow, such as boards, better known by the English name of snowboard.
- the document CH661876 describes a portable device for sharpening a edge, which allows machining the lateral and lower sides of the edge by successively passing the device along the entire length of the edge.
- the device comprises a machining assembly provided with a tool abrasive rotation and a drive motor of the tool, and a frame carrying the machining assembly and equipped with positioning means on the ski.
- the positioning means include first and second support means in two perpendicular directions intended to bear respectively on the edge and on the flat of the ski.
- the chassis is such that the only possible settings are that of the angle of attack of the abrasive tool and that of the depth of pass. This latter adjustment results from a possibility of translation between the machining assembly and the frame in a fixed direction of adjustment relative to the directions of the support means.
- the transition from the machining operation of the lower face to the machining operation of the side face, or vice versa, is practiced by complete reversal of the device, chassis included.
- Such a portable device does not make it possible to overcome the risk of machining the plastic material of the ski constituting the edge or the flat.
- it requires a doubling of the support means: first and second support means for machining the lower face, and first and second support means for machining the side face.
- the passage of the machining operation from one face of the edge to the machining operation of the other face involves a loss of positioning and risks of imprecision of the sharpening obtained .
- the object of the invention is to provide a portable device for sharpening the edges of a ski that is simple, and that allows to machine successively the two sides of a square without risk of inaccuracy of sharpening obtained, while allowing to overcome the risk of machining the plastic of the ski.
- the device according to the invention is remarkable in that the chassis consists of a carriage provided with first and second support means, and a support comprising said fixing means and mounted on the carriage by connecting means having :
- first means allowing a swing of 90 degrees of the support along a pivot axis oriented in a longitudinal direction of the device perpendicular to the lateral-transverse plane, between a first machining position of the lateral face and a second machining position of the lower face
- second means allowing a translation of the support in a second direction of adjustment included in the lateral-transverse plane and perpendicular to the first direction of adjustment.
- the tilting of the support, and therefore of the machining assembly by means of the fastening means allows the carriage to rest simultaneously against the edge and against the flat of the ski during the passage of a machining operation of a face of the edge to the machining operation of the other face. This results in a maintenance of the setting in position and a suppression of the risks of imprecision of the sharpening obtained.
- the translational power of the machining assembly in two perpendicular adjustment directions confers a means for adjusting the depth of pass and an ability to adjust the positioning of the abrasive tool so that it does not machine the plastic of the ski.
- the connecting means comprise means for precisely adjusting the angular position of the support relative to the carriage about the pivot axis in each of the first and second positions.
- Such adjustment means make it possible to adjust more finely, depending on the applications, the angle that forms the lower face of the edge with respect to the flat of the ski after machining and the angle that forms the lateral face of the edge relative to on the underside after machining.
- the connecting means comprise means for precisely adjusting the position of the support relative to the carriage in the second direction of adjustment in each of the first and second positions
- the means of fasteners comprise means for precisely adjusting the position of the machining assembly relative to the support in the first direction of adjustment in each of the first and second positions
- the connecting means are constituted by a linear displacement system having a sliding part connected to the support and a guide part connected to a rotating part of a rotary system of which a fixed part is connected to the carriage
- the first support means comprise rollers intended to roll on the edge of the ski
- the second support means comprise wheels intended to roll on the flat of the ski.
- FIGS. 1 and 2 show an example of a sharpening device in the machining situation of a lower face of a square of a ski, respectively in perspective and laterally
- FIGS. 3 to 5 illustrate the device of FIGS. 2 in the machining situation of a lateral face of the edge, respectively in perspective, laterally and transversely.
