Definitions

  • the present invention relates to a safety ski binding comprising an underfoot plate pivotally mounted on the ski around a vertical axis.
  • This solution requires a relatively very thick plate, which increases the weight of the binding and raises the boot on the ski, reducing control of the ski.
  • the object of the present invention is to obviate the drawbacks of known plate fasteners, including the fastener described in application EP 0 385 944.
  • the safety ski binding according to the invention is characterized in that the pivoting mounting of the plate on the ski is ensured by two profiled parts, respectively male and female, one of which is integral with the plate and the other secured to the ski, these two profiled parts being assembled to one another rotatably by a bayonet device, one of said profiled parts having for this purpose at least one radial finger and the other profiled part at least a groove having a descending part followed by a part in an arc centered on the pivot axis and of a length such that it allows the rotation of the plate necessary for triggering the fixing.
  • This method of mounting the plate on its pivot does not require any auxiliary parts, nor opening through the plate.
  • the plate is therefore not weakened in its central part and the absence of an opening prevents snow from entering the pivot under the pressure of the shoe.
  • the male part can be integral with the ski and the female part with the plate or vice versa.
  • the bayonet groove can be formed on the integral part of the plate, male or female or on the part attached to the ski, male or female.
  • the descending part of the bayonet groove it does not necessarily have to be parallel to the pivot axis, but it can be oblique, curved or even sinuous.
  • Figure 1 shows a side view of the fastener in the closed position.
  • Figure 2 is a top view of this attachment with a cutaway of the plate revealing the pivot.
  • FIG. 3 is a sectional view along III-III of FIG. 2.
  • Figure 4 is a detail of Figure 2.
  • Figure 5 is a side view of the pivot without the plate.
  • Figure 6 is a top view of this pivot also showing the position of the plate for mounting on the pivot.
  • the binding shown is of the same type as the binding described in patent application EP 0 385 944. It essentially comprises a plate 1 pivotally mounted on a ski 2 around a vertical axis 3 and provided at the front with a jaw 4 for holding the front end of a shoe 5 shown in broken lines and, at the rear, a heel piece 6 pivotally mounted on the plate 1 about a vertical axis 7. This heel piece is described in detail in patent application EP 0 385 943 of the applicant.
  • the plate 1 is further supported at the front and at the rear by support and guide means 8 and 9 as described and shown in application EP 0 385 944.
  • the plate 1 consists of two telescopic parts, namely a rear part 1a carrying the heel piece 6 and a front part 1b coming in one piece with the front jaw 4 and mounted sliding inside the posterior part 1a.
  • the part of the front part 1b of the plate opposite the jaw 4 has two parallel rectangular arms 10 and 11 sliding in the part 1a, as can be seen in FIG. 3.
  • the part 1a has a rectangular groove 12 whose width is greater than the distance between the arms 10 and 11, so that the groove 12 and the arms 10 and 11 form a sort of slideway in which the rectangular flange 13 is retained with a body 14 provided a vertical cylindrical bore 15 (Figure 2) in which engages a pivot 16 secured to a base 17 fixed to the ski 2.
  • the body 14 also serves as a support for a worm 18 whose axis 19, parallel when skiing, forms an angle of 25 ° with the axis 20 of the plate 1.
  • the worm 18 is extended by a smooth cylindrical part 21 extending in a clearance 22 formed in part 1a of the plate and opening laterally on the side of the plate.
  • the end of the part 21 is provided with a screw slot 23 allowing the drive of the worm screw by means of a screwdriver.
  • the worm 18 is engaged, from below, with a rack 24 made up of slots parallel to each other and slightly oblique relative to the axis 20 of the plaque.
  • the slots of the rack 24 are also tangent to the helix of the worm 18.
  • the rotary drive of the worm 18 has the effect of displacing the part 1b of the plate relative to the pivot 16.
  • the part 1a of the plate is, in the absence of a shoe, pushed by the spring of the safety mechanism against a stop mounted at the rear and this part 1a must be able to move towards the rear.
  • the length of the groove 12 must be greater than the length of the flange 13 to allow this retreat.
  • the groove 12 can have the form of a housing of the same dimensions as the flange 13.
  • the body 14 is provided with a radial finger 25 projecting inside the bore 15.
  • This finger 25 here constituted by a pin, serves to axially lock the body 14 on the pivot 16 by an engagement of the type bayonet.
  • the plate 17 carrying the pivot 16 is fixed to the ski 2 by means of two screws 26 and 27 ( Figures 5 and 6).
  • the pivot 16 in this case a massive cylindrical male part, is provided with a bayonet groove having a descending part 28 parallel to the pivot axis, open at the upper part of the pivot 16 and opening into a second part 29 in an arc centered on the pivot axis 3 and whose width is substantially greater than the diameter of the finger 25.
  • the plate 1 To mount the plate 1 on its pivot, it is placed obliquely relative to the ski, so that its axis 20 forms an angle of 45 ° with the axis 30 of the ski.
  • the finger 25 In this position, the finger 25 is located opposite the entrance to the groove 28. In FIG. 6, this finger is represented simply by its axis. It is therefore sufficient to vertically engage the finger 25 in the part 28 of the groove, then to bring the axis 20 of the plate parallel to the axis 30 of the ski. The plate is then locked vertically in the direction of the axis 3. In this position 25 ′, the finger 25 can make an angular displacement on either side of this position, this displacement being sufficient to allow the release of the fixing. in torsion, without the plate being able to escape from its pivot.
  • the vertical clearance of the finger 25 in the groove 29 is also sufficient to allow the ski to flex in the region of the binding.
  • the bayonet groove could be provided on the part 14 secured to the plate, the finger 25 then consisting of a pin driven into the pivot 16.
  • the cylindrical male part could be secured to the plate, the piece secured to the ski then being a female part having a cylindrical bore.
  • the male or female part could have come in one piece with part 1a of the plate.
  • the bayonet groove is preferably provided on this part. If the structure of the ski allows, the female part integral with the ski could consist of a recess in the ski.
  • the finger could be machined and have a square or other section.
