Definitions

  • the invention relates to a ski with means for reducing backward sliding.
  • Cross-country skis can have scales in a central region of the ski, which are intended to prevent the ski from sliding back when the cross-country skier pushes off. It is also known to apply grip wax or skins to cross-country skis, which are intended to prevent the ski from sliding back.
  • climbing skins are used to prevent slipping back. They should prevent the skis from slipping backwards during the ascent, but should also allow gliding forwards.
  • a significant disadvantage of known anti-slip devices is that their effect depends very much on the current underground conditions and the temperature. Especially on icy ground, known anti-sliding devices show relatively little effect and can only adequately prevent undesired sliding back. In addition, known anti-slip devices also impair the gliding behavior of the ski in the running direction, which is fundamentally undesirable
  • the invention relates to a ski.
  • the ski comprises a basic ski body with a sliding surface and a binding part to which a skier's boot can be fastened.
  • the binding part is, for example, a commercially available cross-country ski binding or touring ski binding.
  • the binding part is fixed to the basic ski body so that it can be displaced in the longitudinal direction. As a result, the binding part can be shifted between a first and second sliding position in the longitudinal direction of the ski.
  • At least one control surface is provided on the binding part or on a functional part connected to the binding part, which interacts at least indirectly with at least one mandrel displaceably mounted in the ski base body. In particular, the mandrel bears against the control surface with its free end facing away from the sliding surface.
  • the interaction is in particular such that the at least one mandrel is moved, in particular can be displaced, by the displacement of the binding part. This displacement is brought about in particular by the action of the control surface on the free end of the at least one dome.
  • the at least one mandrel is positioned in a first, front sliding position of the binding part in a pushed-back position in which the free end of the mandrel does not protrude beyond the sliding surface, ie the free end of the mandrel is pushed into the basic ski body.
  • the control surface interacts at least indirectly with the mandrel in such a way that when the binding part is displaced relative to the basic ski body from the first, front shifting position to a second, rearward shifting position, for example when the skier pushes off, the mandrel is positioned in an advanced position, in the free end over the sliding surface protrudes in order to prevent the ski from slipping back during the push-off movement by engaging in the ground.
  • the technical advantage of the ski is that a back-slip protection is created, which is activated during the normal course of movement of the skier when pushing off and is deactivated when the ski is subsequently pulled towards it, and can therefore be operated intuitively.
  • the ski offers an effective anti-backslip protection, which has an effective effect against backsliding in different ground conditions, especially when it is heavily icy.
  • the mandrel is positioned in the retracted position by means of a spring. This ensures that the mandrel is pushed into the ski, i.e. the anti-slip device is deactivated, without external force being applied, which can be caused by the skier pushing off, for example.
  • the mandrel can be directly spring-loaded by a spring acting directly on the mandrel.
  • the spring can be a compression spring acting between the ski and the mandrel. It can, for example, run around the circumference of the mandrel.
  • the mandrel can also be indirectly spring-loaded, ie the spring does not act directly on the mandrel but via an intermediate element.
  • the spring can act on the displaceable binding part itself and hold the binding part in the first, front, sliding position without the application of external force.
  • a positive connection can be provided between the binding part or a functional part connected to the binding part and the mandrel.
  • a constrained guidance which at least partially surrounds the mandrel, for example free end side. Due to the form-fitting connection, the mandrel is positioned either in the pushed-back position or in the pushed-forward position, depending on the sliding position of the binding part.
  • the control surface is an inclined plane that is translated in translation when the binding part is displaced in the longitudinal direction of the basic ski body.
  • the at least one mandrel is displaced along its longitudinal axis, specifically from the retracted position, in which the mandrel is positioned due to its spring loading, into an advanced position.
  • a sliding movement of the binding part along the longitudinal axis of the ski can be converted into a sliding direction of the mandrels that runs transversely to this longitudinal axis and is directed downwards.
  • control surface is provided directly on the binding part itself or on a functional part that is detachably attached to the binding part.
  • the functional part can, for example, be an insert that is coupled to the binding part and can be removed separately in order to To be able to carry out maintenance and repair work on the anti-slip device, especially on the spikes.
  • control surface is an inclined plane which forms an acute angle with the sliding surface of the ski, which angle opens counter to the running direction of the ski, i.e. towards the back of the ski.
  • control surface forms an angle with the sliding surface in the range between 10° and 60°, for example between 15° and 45°, preferably between 25° and 35°, in particular between 28° and 32°.
  • the choice of this angle has an advantageous effect on the triggering time of the anti-slip device when the skier pushes off and also leads to a high level of functional reliability.
  • the longitudinal axis of the at least one dome runs obliquely to the sliding surface in such a way that the longitudinal axis of the at least one dome encloses an acute angle with the sliding surface of the ski, which angle opens in the running direction of the ski, i.e. towards the front of the ski.
  • This inclined position of the at least one dome causes it to be pushed out of the sliding surface at an angle to the rear, thereby having an advantageous effect against the ski sliding back.
  • the longitudinal axis of the at least one dome forms an angle with the sliding surface in the range between 30° and 80°, for example between 45° and 75°, preferably between 55° and 65°, in particular between 58° and 62° a.
  • This inclined position of the at least one pin is advantageous because a particularly effective means of preventing the pin from slipping back is achieved, while at the same time the pins are pushed out safely, which is synchronized with the sequence of movements of the skier.
  • At least two mandrels are provided, which are arranged one behind the other as seen in the longitudinal direction.
  • the longitudinal axes of the at least two mandrels run parallel to one another.
  • the spikes in the ski are oriented in a similar way and engage the ground in the same direction.
  • the mandrels can be controlled with an identically designed sliding gate in the form of control surfaces oriented in the same way.
  • the spikes are provided centrally or substantially centrally in the ski with respect to the transverse direction of the ski.
  • the spikes come to lie one behind the other as seen in the longitudinal direction of the ski, which offers advantages with regard to the integration of the spikes into the ski.
  • At least two spikes are arranged laterally offset from one another, viewed in the longitudinal direction of the ski.
  • the binding part is slidably guided in a rail attached to the basic ski body.
  • a sliding guide for the binding part is achieved, so that the binding part slide slightly backwards when the skier pushes off and thus the anti-slip device can be activated.
  • the binding part is designed to be shifted from a front position to a rear position, which is shifted counter to the running direction, when the skier pushes off. As a result, triggered by the skier's normal movement sequence, activation of the anti-slip device is achieved.
  • the displacement path of the binding part is less than 5 cm, preferably less than 3 cm. With a very small displacement path, which is hardly noticeable to the skier, the slide back of the ski can be effectively reduced.
  • the ski can be a cross-country ski or a touring ski.
  • the free end of the dome protruding from the ski in the advanced position can be bolt-like and, for example, tapered or tapered to a point.
  • the free end of the dome can form a flat, for example platelet-shaped or spade-like section that runs transversely to the running direction, so that a large-scale intervention in the snow can be achieved. This can be particularly advantageous for touring skis.
  • FIG. 1 is an example of a plan view of a ski binding from above;
  • FIG. 2 shows an example of a longitudinal section through the ski binding along the section line A-A according to FIG. 1 , the binding part moving the pins being in the forward sliding position and the pins thus being pushed into the basic ski body;
  • FIG. 3 shows an example of a longitudinal section through the ski binding along section line AA according to FIG.
  • FIG. 1 shows, by way of example and schematically, a plan view of a section of a ski 1 on which a binding part 4 is provided.
  • the ski 1 has a basic ski body 2 with a sliding surface 3 in a known manner.
  • the ski 1 can, for example, be a touring ski or a cross-country ski, in particular a cross-country ski for classic cross-country skiing.
  • the ski 1 has a running direction LR, as shown in FIG
  • the formation part 4 has fixing means to which a skier's shoe can be fixed.
  • the fixing means are designed in such a way that they interact with corresponding fixing means provided on the front of the shoe, so that a detachable connection is created between the skier's shoe and the ski.
  • the binding part 4 is held displaceably on the ski base body 2 in such a way that the formation part 4 can be displaced in the longitudinal direction of the ski 1 relative to the ski base body 2 . This allows him
  • Binding part 4 can be moved to the ski 1 between a front position and a rear position.
  • one or more rails running in the longitudinal direction LR of the ski 1 can be provided on the upper side of the ski base body 2 .
  • the binding part 4 can, for example, be guided in this at least one rail in a form-fitting manner.
  • the binding part 4 is designed to move the mandrels 6, 6' from a pushed back position, as shown in FIG. 2, into a pushed position, as shown in FIG 3 is shown to bring.

  • the mandrels 6, 6' are pushed back into the position positioned so that they no longer dig into the snow or ice.
  • the binding part 4 has at least one control surface 5, by means of which the sliding movement of the binding part 4 is converted into a sliding movement of the pins 6.
