Definitions

  • the present invention relates to a safety binding a ski boot with an overflowing sole on a ski, comprising a jaw with two arms independent so as to open opposite one of the other during the fitting and able to retain vertically the shoe by its overflowing sole, the jaw can pivot laterally under the action of the shoe against the action of a return spring.
  • the invention particularly relates to a fixing intended to fix the front end of the shoe, but it could also apply to fixation from the back end of the shoe.
  • the jaw retains the shoe laterally and vertically by the protruding part of the sole by two arms independent so as to open opposite one of the other when putting on.
  • a another disadvantage of this type of attachment is the accumulation of snow under the jaws, between these and the ski or the plate on which comes slide the sole of the shoe sideways.
  • Patent EP 0 241 360 illustrates a fixing of the second type.
  • the shoe is retained laterally by its rod and vertically by the face upper of the overflowing sole the arms take so support at points further from the axis of the shoe and on a much more rounded surface than the end of the sole, so that obtains a large elastic stroke.
  • the arms of the jaw are at a significantly higher height raised above the sole support plate and skiing so that snow is not retained under the jaw.
  • a disadvantage of such a fixation is the high pressure of the jaw on the upper, that is to say the shell of the shoe, which does not not stiffness and resistance of the sole and which can therefore be deformed under the pressure of the jaw by totally changing the conditions of release of fixation.
  • Another downside lies in the fact that during a fall before the the entire forward thrust is exerted on the arm, which can trigger the front fixing, while this is the role of the heel to trigger.
  • the fixation of the third type includes two arms bearing on the shoe upper and a front stop against which rests on the sole.
  • the arms are tied rigidly to the pivoting body of the binding and they don't cannot deviate from each other.
  • the arm spacing is adjustable by means of stop screws. Such a setting is delicate. If the arms are too pinched, the rod is crushed when the sole stops. The stem deformation and increased surface area contact of the arms with the rod, which result therefrom, may interfere with the release of the binding. If the arms are too far apart, which can result from adjustment, a game appears, which results in a poor ski guidance and therefore a feeling insecurity.
  • the object of the present invention is to provide a ski binding with all the advantages of known fasteners, but not requiring adjustment manual of the jaw arms.
  • the front stop means are preferably made up of rollers with vertical axis.
  • rollers can be mounted on the jaw, preferably around axes separate from the axes of pivoting of the jaw arms.
  • the parts of the arms of the jaw bearing against the rod advantageously have a low coefficient of friction or are fitted with rollers.
  • Figure 1 is a perspective view from above of the fixing, in this case a front stop according to a first mode of execution.
  • Figure 2 is a perspective view from below, shoe shown in mixed lines, of the same mode execution.
  • Figure 3 is a bottom view of the binding, without the body of it and without the backing plate of the sole, the shoe being engaged in the stop under the push of a rear or heel binding.
  • Figure 4 is an axial sectional view, along line IV-IV of Figure 5, of a second embodiment
  • Figure 5 is a plan view, partially in section according to V-V of FIG. 4, of this second mode execution.
  • Figure 6 is a top view of the right jaw of an alternative embodiment of the first embodiment.
  • Figure 7 is a sectional view along VII-VII of the figure 6.
  • the binding shown in Figures 1 to 3 includes a base 1 on which a fixing body 2 is mounted carrying a jaw made up of two arms 3 and 4 mounted tilting, independently, around two vertical axes located on either side of the axis longitudinal of the binding, as described and shown in patent EP 0 295 372.
  • These arms 3 and 4 constitute levers of the first kind whose inner ends act on a tie rod 5 whose end 5a rests on a socket 6 against the bottom of which is supported a working spring 7 in compression between the bottom of the socket and a face 8.
  • This construction is similar to the construction described in patent EP 0 295 372.
  • the jaws 3 and 4 are located at such a height, relative to the base 1, that when the shoe 9 is engaged in the stop, arms 3 and 4 are located above the standard sole 10 of the shoe and come to rest on the rod 11 of the shoe. In their support zone arms 3 and 4 are advantageously provided with inserts with low coefficient of friction.
  • the arms 3 and 4 respectively carry a roller 12 and 13 mounted around a vertical axis 14, respectively 15, distinct from the pivot axis of the arm corresponding and located between this pivot axis and the part of the arm resting against the rod of the shoe.
  • the rollers 12 and 13 constitute means front stop for the front part 10a of the sole 10 which projects in front of the upper 11.
  • Each of arms 3 and 4 could be provided with one or several rollers by which the arms would take support on the upper of the shoe.
  • the second embodiment differs from the first embodiment in that the front stop means consist of a stop 17 secured to the base 1. In the particular case, this stop 17 came in one piece with the base. On the Figure 5 we see the vertical rib 18 on which swivels the arm 3.
  • the stop 17 could also be provided with rollers.
  • the jaw 3 ' seen from below in FIG. 6, like the jaw 3 of Figure 3, is provided with a part reported 30 with low coefficient of friction intended to come to rest on the upper of the shoe, as previously described.
  • This part 30 presents a hole 31, as well as a slot 32 perpendicular to the axis of the hole 31.
  • the part 30 is mounted in a housing 20 jaw 3 'having a rib 21 engaging in slot 32.
  • the jaw 3 ' is further provided with a roller 12 located below part 30 and intended to serve as support for the front part of the sole of the shoe.
  • This roller 12 is mounted in a housing 22 of the jaw 3 '.
  • roller 12 and the support piece 30 are retained in the 3 'jaw by means of a common pin 23 driven out in a hole 24 passing through the housings 20 and 22 of the jaw.
  • the pin 23 In its lower half, the pin 23 has a reduced section portion 23a allowing the roller 12 to rotate with play around the pin 23.
  • FIG. 6 there is also a distinction on the jaw 3 ', a hole 25 for the passage of an axis 26, indicated in dashed lines in Figure 7 for the connection of the grip jaw 5 shown in Figure 3, as well that a rounded notch 27 constituting the point of pivoting of the jaw on the rib 18 of the body of the attachment, as shown in Figure 5 and described in EP patent No. 0 295 372.
  • the left jaw is made identically.
