Definitions

  • the present invention relates to a ski touring binding, allowing the retention of a shoe on a ski touring while selectively allowing the pivoting of the shoe for walking.
  • fasteners comprising an elongated base, which may be a plate with or without openings, or which may be formed of one or more metal rods.
  • the elongated base is articulated by its front part freely around an axis located transversely to the ski. This elongated base comprises at the front a stop against which the front point of the shoe bears, and comprises at the rear a heel piece intended to secure the shoe with the elongated base.
  • Means for releasing the boot are generally provided, both on the front stop and on the heel piece, to allow the boot to be released automatically when efforts dangerous to the skier's leg are exerted either in the direction of the front, or in lateral direction, that is to say in torsion.
  • the transverse axis of rotation of the elongated base is fixed on the ski
  • a system for retaining the rear of the elongated base is itself movable on the ski so as to be moved by actuation of a control placed behind the elongated base.
  • the known fasteners have certain drawbacks.
  • the free rotation state walking position on the flat or uphill
  • the immobilized state downhill ski position
  • the moving masses under the heel can be tiring, especially when used by light people.
  • An object of the invention is to provide a binding which avoids the drawbacks mentioned above of known hiking bindings.
  • the ski touring binding according to the invention must therefore have great ease of control, to easily pass between the state of free rotation and the immobilized state without having to contort or take off.
  • the ski touring binding according to the invention must both have great ease of control and a minimum weight.
  • control means according to the invention can be operated by vertical support. It then becomes possible to maneuver the controls using a stick which is pressed in front of you, in a comfortable and ergonomic position. The user has significant force to press a stick placed in front of him. It is thus understood that the binding according to the invention then becomes very easy to use, even by loaded or disabled people.
  • control means comprise a front block adaptable to the ski and comprising two vertical pushers, a vertical push on the first pushbutton actuating the means of selective locking in rotation to achieve the locking in rotation of the elongated base , a vertical thrust on the second pusher actuating the selective locking means in rotation to achieve unlocking in rotation of the elongated base.
  • control means comprise a front block adaptable to the ski and comprising a maneuvering lever with vertical actuation, a first vertical thrust on the maneuvering lever actuating the selective locking means in rotation in order to unlock in rotation the elongated base, a second vertical thrust on the maneuvering lever actuating the means of selective locking in rotation to achieve locking in rotation of the elongated base.
  • the pushers or the operating lever act on cams and levers to move a connecting element in antero-posterior movement which functionally connects them to the selective locking means in rotation.
  • This arrangement is particularly effective, because the user can act simultaneously on his foot by advancing or retreating it, in the direction which favors the passage towards the locking or unlocking position in desired rotation, in cooperation with the means of ordered.
  • the fixed anchor is shaped to constitute a climbing wedge, and forms a stop which opposes the pivoting of the elongated base towards the descent position when the front support is in the rotation locking position.
  • the invention further provides a special abutment structure before fixing.
  • a trekking binding according to the invention comprises an elongated base 1 which is articulated according to its anterior zone on an anterior support 2 adaptable to a ski 3.
  • the elongated base 1 can pivot about a transverse articulation axis 4 of the front support 2 between a descent position, illustrated in FIG. 1, in which it is in abutment on the upper face of the ski 3, and a raised position, illustrated in the figures 2 and 3, in which the rear part of the elongated base 1 is pivoted upwards away from the ski 3.
  • the elongated base 1 can freely pivot around the transverse articulation axis 4 as illustrated by arrow 5, to follow the flexion movements of the user's leg and foot when walking flat or uphill.
  • Selective rotation locking means 6 make it possible to selectively lock in rotation the elongated base 1 in the descent position (FIG. 1), while preventing it from being pivoted, and allow the elongated base 1 to be unlocked in rotation while allowing free pivoting 5 between the lowering position and the raised position.
  • Control means 7, accessible by the user, are located in front of the elongated base 1, and make it possible to actuate the selective locking means in rotation 6 in order to obtain the locking and unlocking in rotation of the elongated base 1.
  • the elongated base 1 comprises means for retaining a shoe.
  • the retaining means comprise a front stop 8 and a heel piece 9.
  • the front stop 8 comprises a movable jaw 10 pivotally mounted on a base 11 around a first vertical axis 12.

  • the front support 2 is movable in antero-posterior movement on the ski 3 between the remote position illustrated in FIG. 1 and producing the locking in rotation, and the advanced position illustrated in FIGS. 2 and 3 authorizing the pivoting 5 after unlocking in rotation.
  • the front support 2 has the shape of a stirrup, consisting of a base plate 2a secured to two side flanges 2b and 2c each having a hole 2d or 2e for passage of the transverse articulation axis 4.
  • the base plate 2a is movable on the ski in an anteroposterior movement illustrated by the arrow 2f.
  • the front support 2 moves longitudinally along a plane.
  • the front support 2 can be mounted on guides shaped so that the transverse articulation axis 4 moves in an arc between the positions of locking in rotation and unlocking in rotation of the front support 2.
  • the front support 2 can be mounted on guides shaped so that the transverse articulation axis 4 is located at a different distance above the ski 3 depending on whether it is in the rotation locking position or in the unlocking position in rotation.
