Definitions

  • the present invention relates to the technical sector concerning ski mountaineering bindings, with particular reference to a toe-piece of the ski binding.
  • ITM020070365 describes a toe-piece of a ski binding for ski mountaineering, which comprises: a base which is fixable to a ski; a first jaw which is coupled in a revolute pair to the base so as to rotate with respect to a first axis of rotation which is parallel to the axis of the ski when the base is fixed to the ski; a second jaw which is rotatably coupled in a revolute pair to the base with respect to a second axis of rotation which is parallel to the first axis of rotation; a first pin which is borne by the first jaw for inserting in a first lateral hole fashioned in a tip of a ski boot; a second pin which is borne by the second jaw for inserting in a second lateral hole opposite the first lateral hole fashioned in the tip of the ski boot; an activating lever which is coupled in a revolute pair to the base with respect to a third axis of rotation which is perpendicular to the first axis of rotation; a joint
  • a drawback of this toe-piece of the ski binding consists in the fact that during use snow inserts between the joint and the ski, where it might get compacted and thus might be an obstacle to the correct functioning of the toe-piece of the ski binding.
  • the aim of the present invention consists in at least limiting the above-mentioned drawback.
  • the quantity of snow that inserts between the joint and the ski is advantageously smaller.
  • the snow was able to pass between the turns of the springs, while with the invention the first spring is closed by the first jaw and the first portion of joint.
  • the lateral walls that rise from the base flank both frontally and posteriorly the first jaw, the first portion of joint, the second portion of joint and the second jaw in such a measure as to at least limit the passage of snow.
  • the height of the lateral walls at least partially closes the gap between the lateral walls, on one side, and the first jaw, the first portion of joint, the second portion of joint and the second jaw, on the other side.
  • reference numeral (1) denotes in its entirety a toe-piece of the ski binding for ski mountaineering according to the present invention, comprising: a base (2) which is fixable to a ski (30); a first jaw (11) which is rotatably coupled to the base (2) with respect to a first axis of rotation (R1) which is parallel to the axis of the ski (30) when the base (2) is fixed to the ski (30); a second jaw (12) which is rotatably coupled with the base (2) with respect to a second axis of rotation (R2) which is parallel to the first axis of rotation (R1); a first pin (21) which is borne by the first jaw (11) for inserting in a first lateral hole (31) made in a tip of a ski boot (40); a second pin (22) which is borne by the second jaw (12) for inserting in a second lateral hole (32) fashioned in the tip of the ski boot (40); an activating lever (3) which is rotatably coupled to the
