Definitions

  • the invention relates to a toe piece for a touring ski binding with a base and at least one recess or through-opening in the base, lateral sole holders with sole holder pins or pins that can connect the toe piece to a ski boot, so that the ski boot can be turned in the toe piece in a touring mode of the binding an axis transverse to a longitudinal axis of the binding can pivot in the skiing direction.
  • the toe piece further includes tensioning means for tensioning the sole holders and optionally a locking device with which the sole holders can be locked in the position in which they are connected to the ski boot.
  • a toe piece for a touring binding is known, with a toe piece, which comprises two opposite bearing sections running parallel to a longitudinal axis of the binding and a separate front stop, which facilitate the correct stepping into the binding with a shoe.
  • Another toe piece for touring bindings is from the EP 2 308 568 A1 known.
  • the WO 02/13643 A1 relates to a crampon with a frame-shaped footprint for a front and a rear part of a shoe. The area inside the frame is covered with a membrane, which ensures that no snow can stick to the underside of the crampon, as it is repeatedly pushed off when walking with the crampon due to the twisting of the frame and the resulting movement of the membrane .
  • the weight of the ski with the binding plays an increasingly important role, since every gram of weight saved makes touring easier. It is therefore an object of the invention to provide a toe piece for a touring ski binding that has a low inherent weight, is safe, consists of as few individual parts as possible and can be manufactured inexpensively.
  • One aspect of the invention relates to a toe piece for a touring ski binding with a base having at least one depression or through-opening in the base.
  • the toe piece comprises two sole holders with sole holder pins, which can engage laterally in the sole of the ski boot in corresponding receptacles in order to hold the ski boot in the toe piece when touring and preferably also when going downhill, so that the ski boot can rotate about an axis when touring, which passes through the Sole holder pins and the recordings of the ski boot sole runs, can be pivoted.
  • the sole holder pins can in particular be two opposite bearing sections with respect to a longitudinal axis of the ski, which interact with the corresponding receptacles on the sides of the ski boot sole facing them, which form a counter bearing for the bearing sections.
  • the sole holder pins or bearing sections can be moved into and out of the counter bearings essentially transversely to the longitudinal axis of the ski by pivoting the sole holders.
  • the counter-bearing and the bearing elements accommodated therein define a pivot axis transverse to the longitudinal axis of the ski and connect the ski boot to the touring ski binding in a pivotable manner in the pivot axis.
  • the touring ski binding In the pivoted-away state, in which the bearing elements no longer engage in the counter bearing, the touring ski binding is in an open position, so that the user can get in or out of the touring ski binding.
  • the toe piece also includes clamping means for clamping the sole holder and optionally a locking device with which the sole holder can be locked at least for walking.
  • the front jaw comprises at least one cover made of an elastic material, which covers, preferably at least substantially completely, the at least one depression or through-opening in the base.
  • a base is understood here as a component for a toe piece that can be connected to a ski or a binding plate that can be connected to the ski, preferably in a stationary manner, and that is prepared to accommodate the sole holder and optionally assume other functions.
  • the base or the base body preferably surrounds the at least one depression or through-opening in the form of a frame, that is to say frames it completely, preferably without an opening or interruption in the frame-shaped component.
  • the base for the front jaw can be formed in a single part, for example made of a plastic that is not very deformable or a light metal such as aluminum or magnesium, for example in an injection molding process or a generative process.
  • the base can also consist of several Be constructed materials, that is, for example, plastic and / or a metal and / or include several metals.
  • the plastic can be a reinforced plastic. The reinforcement can be done for example by glass, carbon, metal or other suitable materials.
  • the base can be made off-tool, which means that it requires no or only negligible post-processing.
  • the indentation can be an area that is recessed and essentially planar with respect to the rest of the geometry of the base and is suitable for receiving the cover.
  • the recess can be a flat, for example pot-shaped, recess with a flat bottom.
  • the depression can also be subdivided by one or more elevations, for example strut-shaped elevations, wherein if there are several elevations, the elevations can have the same or less height than the depression edge that connects the bottom of the depression to the top of the base.
  • the cover or covers may each also be made in one piece as a separate part from the base, for example from a resilient plastics material such as an elastomer, preferably a thermoplastic elastomer such as TPU.
  • a resilient plastics material such as an elastomer, preferably a thermoplastic elastomer such as TPU.
  • the cover for the recess is preferably connected to the base on an upper side of the base facing away from the ski surface, the cover for the through-opening is preferably connected to and/or in the recess with the base.
  • the base has the through-opening, as is preferred, an underside of the base facing the ski surface can be connected to it. If the base or the toe piece is connected to the ski, the cover can no longer detach from the base.
  • the base and cover(s) may be integrally bonded to one another.
  • the cover(s) can be welded or glued to the base, or the base and cover(s) can be molded together, for example in a two-component injection molding process.

  • the base can form a basic structure for one stop, and the stop itself can be formed from an elastic material, which is preferably detachably connected to this basic structure, for example by a positive fit.
  • Forming the stop from an elastic material has the advantage that manufacturing tolerances of the ski boot sole can be compensated for automatically, so that it is easy to step into the binding and the ski boot is firmly held in the binding, regardless of any manufacturing tolerances of the sole.
  • the elastic material for the stop can advantageously be the same material from which the cover is made. It can be particularly advantageous if the stop can be connected or is connected to the cover. It is even more advantageous if the stop is molded in one piece with the cover or one of the covers, that is to say it is produced, for example, in a mold in a thermoplastic injection molding process, preferably off-the-tool.
  • the stop can consist of two partial stops which are spaced apart from one another in a direction transverse to a longitudinal central axis of the binding.

  • Each of the sole holders can include a tensioning means, such as preferably a single spring, which tensions the respective sole holder in a first and/or a second position.
  • the pivot axis for the further pivot joint preferably runs essentially parallel to the central longitudinal axis of the ski binding.
  • the toe holder or toe piece of the exemplary embodiment shown is the toe piece of a pin binding and comprises two sole holders 13, each with a pin 14, which can engage in openings formed on the ski boot or the ski boot sole to connect a ski to a ski boot.
