Definitions

  • the invention concerns a cross country ski allowing a quick exchange of sliding, rebounding or anti-backwards sliding technologies in the course of skiing depending on changing outdoor conditions or the skier's decision on the selection of skiing style.
  • a ski in particular a cross country ski, is manufactured as a multi-layer body comprising a shell casing whose sectional view is substantially in the shape of an inverted "U" letter, whose base forms the upper side of the ski body and whose arms form the sides of the ski body.
  • a core made of light-weight material reinforced by a firm carbon layer is mounted inside the shell casing.
  • the body also includes a running surface and force distribution element arranged between the casing and running surface at least in the kick and grip zone of the ski, or alternatively exceeding this zone on one or both ends in the longitudinal direction of the ski.
  • the US 4,165,886 patent discloses the cross country ski whose running surface is equipped with at least one groove accommodating a replacement element whose surface prevents backwards sliding.
  • the element is self-adhesive on one side and is stuck to an interface layer between the running surface and the ski body. It is also possible to stick a replacement element with smooth surface or waxed surface for downhill skiing instead of the replacement element preventing backwards sliding. This will adapt the ski to snow conditions and sports requirements.
  • a disadvantage of the solution according to the US 4,165,886 patent rests in the fact that the skier must keep a large number of elements with various surfaces corresponding to different snow conditions as only one side of the element can be used for sliding or bouncing whereas the other side of the element is always equipped with a self-adhesive fixing layer designed to fix the element. Under winter conditions fixing using a self-adhesive layer is not possible in the field; the exchange must be done by a specialist service provider. This solution did not work in practice and is no longer used.
  • the EP 0473898 patent discloses a solution for the cross country ski which is on its lower side equipped with a flat recess in the area of the kick and grip zone.
  • the recess has side grooves into which the replacement element that must be bent beforehand is inserted.
  • the element is held in the recess by friction force produced in the grooves. Its surface can be equipped with a means preventing backwards sliding or it can be smooth.
  • a disadvantage of the solution disclosed in the EP 0473898 patent rests in the fact that it is very difficult to insert and extract the element as at lower temperatures the plastic material stiffens and gets fragile and becomes too difficult to bend. Moreover, snow or ice can get into the grooves, which makes the exchange of the element in the field even more difficult.
  • the US 6,659,492 patent discloses a solution for ski mountaineering that is equipped with a replacement element insertable into grooves in a recess similarly as in the EP 0473898 document with the only difference that the element does not need to be bend.
  • the element is inserted into the recess from the front or from the back of the ski and the recess runs along the entire length of the ski.
  • the element is equipped with side pads fitting into the grooves.
  • One side of the element is rough for climbing up the hill whereas the other side is smooth for downhill skiing.
  • the element must be secured against longitudinal motion by screws and stops.
  • the element can be alternatively placed only in the kick and grip zone of the ski, not along its entire length.
  • the ski running surface is equipped with a band containing a means preventing backwards sliding of the ski.
  • the front part of the band fits into the recess in the running surface where it is secured using a pressure plate.
  • the pressure plate is tightened using a screw or cam from the upper side of the ski.
  • the solution can be used for ski mountaineering skis but it is not suitable for cross country skis.
  • the transition between the pressure plate and the band aggravates and slows down the ski movement, which is a critical disadvantage in the case of cross country skis.
  • the EP 2452729 B1 patent (Atomic Austria GmbH) discloses the cross country ski where the means preventing backwards sliding consists of a furry, brushy or scaled profile arranged on a supporting member stable in terms of dimensions and bending.
  • the supporting member is deposited in the recess in the running surface with the possibility of extraction and exchange thereof.
  • the recess is formed in at least part of the kick and grip zone of the ski and reaches as far as the force distribution element so that the base surface of the recess is formed and confined by the material of the force distribution element.
  • the front and rear ends of the recess and supporting member are identically shaped into profile locks.
  • the supporting member is made from hardened plastic material.
  • the EP 2452729 B1 patent mentions the magnetic fixing of the supporting member in the recess.
  • the fixing of the supporting member is also described by another document EP 2295120 B1 (Atomic Austria GmbH). It is always only the lower side of the supporting member that is smooth or scaled or has brushy textile preventing backwards sliding stuck onto it.
  • Velcro fasteners or discs from ferromagnetic material are protruding on the upper side of the supporting member and fit against the matching counterparts of the Velcro fastener or permanent magnets mounted in the recess.
  • the upper side of the supporting member is not used for skiing.
  • the rear end of the supporting member is equipped with a small opening into which a fixture for the extraction of the supporting member is inserted.
  • the skis according to EP 2452 729 B1 and EP 2295 120 B1 allow a quick exchange of sliding, rebounding or anti-backwards sliding technologies in the course of skiing depending on changing outdoor conditions or the skier's decision on the selection or change of skiing style.
  • Their disadvantage rests in the fact that the supporting members can be equipped with various surfaces but always on one side only. This means that if the skier intends to exchange a smooth running surface for a smooth running surface with wax, scales or brushy textile, they must carry four supporting members.
  • EP 2745886 A1 (Atomic Austria GmbH) discloses the disadvantages of the solution provided in EP 2452729 B1 and EP 2295120 B1 which have been resolved by the removal of the supporting member from plastic material.
  • bendable textile bands with flexible shapes equipped on one side with a self-adhesive layer and on the other side with a means preventing backwards sliding are used. These bands are positioned in the recess where they are stuck and can be unstuck and extracted again.
  • the bands have, at least on one end, a positioning fixture cooperating with the groove on the lower side of the ski which is used for precise inserting and extracting the band.
  • the positioning fixture can be formed by a positioning edge, bolt, magnetic plate and other embodiment examples.
  • the disadvantage consists again in the fact that only one side of the band can be utilized for skiing and also that the band cannot be exchanged by the skier themselves. The exchange must be implemented by a specialist service provider. Therefore, the skis according to the EP 2745886 A1 patent cannot be used for quick changes in snow conditions and cross country skiing styles during skiing.
  • the international patent application WO 2016/045115 A1 also discloses the climbing and downhill skiing ski which has a supporting member equipped with a means preventing backwards sliding designed in a similar manner as that disclosed in EP 2452729 B1 , which means with profile locks and magnets for fixing.
  • the supporting member is smooth on the other side, which means that it can be turned by 180° and used for downhill skiing.
  • the supporting member is fixed and released using a holding device positioned on the rear side of the ski.
  • the holding device is tiltable, its lower part grips the rear edge of the supporting member and its upper lever part tilts onto the lower surface of the ski and grips the supporting member.
  • the purpose of the invention is to manufacture the cross country ski which would eliminate the drawbacks of the solutions described above, in particular according to EP 2452729 B1 and EP 2295120 B1 , in particular which would allow the all-purpose use of one skis for alternating run, for sliding with both arms as well as for the skating style with the possibility of a quick exchange of the sliding, rebounding or anti-backwards sliding technologies directly in the field depending on external weather conditions, track and the skier's requirements.
  • Another task of the invention is to reduce the weight and number of items of the skier's equipment necessary for such an exchange.
  • Another task of the invention is to create an extraction means for the supporting member which would allow the supporting member to be turned and exchanged very quickly and easily even at very low temperatures without the respective components become blocked by snow or ice.
  • Another task is the solution of the extraction means in a manner possibly allowing the skier to exchange the supporting member without having to take the ski off.
  • the task of the invention is to provide the solution of the supporting member whose surfaces would not tend to get frozen and covered with snow during skiing.
  • the ski is manufactured as a multi-layer body comprising a shell casing whose sectional view is substantially in the shape of an inverted "U" letter.
  • the ski comprises a core filling in the casing, a strength member arranged at least on the lower side of the core, a binding fixed on the upper side of the ski or at least an area for fixing the binding, a running surface on the lower side of the ski and a force distribution element arranged between the running surface and the strength member.
  • the force distribution element defines a kick and grip zone where the ski has improved strength and elastic properties.
  • the binding comprises a fixing head and a rebound plate, both arranged on the upper side of the ski.
  • the running surface and force distribution element in the kick and grip zone of the ski comprise a recess running in the longitudinal direction of the ski where a replaceable supporting member in the shape of a dimensionally stable band, whose at least one side is smooth or equipped with a means preventing backwards sliding, is inserted in an extractable manner.
  • a replaceable supporting member in the shape of a dimensionally stable band, whose at least one side is smooth or equipped with a means preventing backwards sliding, is inserted in an extractable manner.
  • At the bottom of the recess at least one permanent magnet attracting at least one ferromagnetic segment positioned in the supporting member is mounted.
  • the position of the permanent magnet - ferromagnetic segment can be inverted.
  • the ski comprises a general extraction means to put the supporting member further away from the recess bottom, and eject the lower side of the supporting member above the running surface level to make it possible to take a grip of, extract and exchange the supporting element.
  • the extraction means consists of a case which is mounted inside the ski in the area of the kick or grip zone and open to connect the upper side of the casing with the recess and which also comprises a pressure member mounted in the case in a movable manner with the possibility of movement between the upper extreme position, where the pressure member is completely outside the recess, and the lower extreme position where the pressure member reaches as far as the recess by a minimum of the length l ⁇ t, where t refers to the total thickness of the supporting member, i.e. the thickness of the supporting member, including the means preventing backwards sliding, provided that it is used on the supporting member.
  • the case is arranged in front of the binding, i.e. in the area between the fixing head of the binding and the front end of the kick or grip zone, or between the rear end of the rebound plate and the rear end of the kick or grip plate.
  • binding also refers to the equivalent term "area designed for fixing the binding”. The preference related to this embodiment rests in the fact that the extraction means does not reach the binding structure and can be mounted on various types of cross country skis with various types of binding, including retrofitting.
  • the case is arranged in the binding area, i.e. in the area of the fixing head of the binding or in the area of the rebound plate of the binding.
  • the case consists of a watertight element with a through hole where a movable pressure member consisting of a pin is mounted.
  • the case and the pin have preferably a circular cross section.
  • the case with the pressure member can have a number of other possible shapes, however, the circular cross section is easy to manufacture and reliable in terms of function.
  • the element and the pin can be made from metallic, composite or plastic material. The element either forms an integral part of the ski and is integrated during manufacture, or is stuck into an additionally drilled bore.
  • the pin can be a very simple, one-piece pin, but in the preferred embodiment the pin is two-piece and consists of a control pin and a tubular pressure pin and the pressure pin is mounted in the case in a movable manner, the control pin is mounted in the pressure pin in a movable manner, and the pins are equipped with means allowing mutually releasable coupling of their movement towards the recess.
  • the means for mutually releasable coupling of the pins movement preferably consist of a guiding bolt protruding from the control pin and a groove formed in the pressure pin, and the control pin is equipped with a control head allowing the control pin to be turned to make the guiding bolt fit into the groove.
  • control pin and groove form a simple bayonet joint of both pins.
  • the advantage of this arrangement rests in the fact that the whole pressure member in the engaged position of the control pin is short and does not protrude much on the upper side of the ski. In the disengaged and turned position of the control pin the control pin connects the pressure pin and the connected length of the pressure member is then sufficient to press the supporting member out of the recess.
  • the pin is mounted on a spring in the case and in its upper part it is equipped with a pressing head placed in a watertight flexible cover connected to the upper side of the ski.
  • the case consists of a watertight element with a through hole where a movable pressure member consisting of a lever equipped with control and pressure ends reaching the recess is mounted.
  • a movable pressure member consisting of a lever equipped with control and pressure ends reaching the recess.
  • the lever can be mounted directly in the ski outside the area designed for fixing the binding, or, in the particularly preferred embodiment, the control end of the lever can be formed by the control member of the binding or it can be connected to it.
  • the control member of the binding refers in particular to a rotary cover of the fixing head that is used in particular with racing cross country skis and whose movement controls the fixing and releasing of the tip of the cross country ski boot in the fixing head. This embodiment assumes that the boot is automatically released from the binding when the supporting member is exchanged or turned.
  • the design of the extraction means according to the invention allows the extraction of the supporting member from the upper side of the ski to be controlled, and it also allows a double supporting member to be used.
  • This preferred embodiment rests in the fact that the upper side of the supporting member is smooth and manufactured from the same material as the running surface, or that it is equipped with a means preventing backwards sliding and the lower side of the supporting member is smooth and manufactured from the same material as the running surface, or that it is equipped with a means preventing backwards sliding where at least one ferromagnetic segment is mounted inside the supporting member between its upper side and lower side.
  • the ferromagnetic segment can be substituted by a permanent magnet but it is always mounted in a manner that it does not protrude onto the surface of the supporting member.
  • the whole supporting member is manufactured from the same material as the running surface, for example polyethylene with added graphite. It is possible to apply for example wax for hard and frozen snow onto one side of the supporting member while klister for soft snow and skiing at high temperatures can be applied on the other side.
  • one side of the supporting member can be equipped with brushy textile or scales for climbing. The use of individual means preventing backwards sliding and smooth sides of the supporting member can be combined at will.
  • the skier can thus have at their disposal several supporting members whose surfaces have been premeditated with respect to the character of the track and weather forecast. During skiing, only the supporting members are exchanged.
  • the skier can be equipped with supporting members having all-purpose surfaces for individual contacts.
  • the bottom of the recess is equipped with an anti-adhesive layer preventing wax or klister forming a means that prevent backwards sliding from sticking.
  • the bottom of the recess is equipped with spacer pads allowing the side of the supporting member equipped with the means preventing backwards sliding formed by brushy textile or wax or klister to sit down.
  • the spacer pads not only prevent wax sticking but also in the case that the brushy textile is used they eliminate its flexibility and keep the supporting member in a constant position.
  • the advantages of the cross country ski according to the disclosed invention rest in particular in the fact that the ski allows supporting members with various surfaces to be exchanged quickly and effectively during skiing depending on the track nature and weather.
  • the design of the extraction means allows this exchange to be implemented very quickly and easily even at low temperatures without having to take off the ski.
  • the supporting member does not get frozen and its double design provides a very high variability of ready-to-use surfaces while the total number of elements necessary for racing or recreational skiing is reduced to the minimum.
  • the invention provides all skiers, no matter whether racers, amateurs or tourists, with the possibility to employ all styles (skate, with both arms, standard) with only one type, or where applicable, one pair of skis when doing cross country skiing.
  • the ski according to the invention allows optimal skiing on all kinds of snow.
  • cross country ski The greatest benefit of the cross country ski is that it simplifies the choice of cross country skis for beginners but also advanced skiers due to its all-purpose character.
  • the use of the cross country ski according to the invention will popularize cross country skiing among the non-specialist public because if the beginner chooses unsuitable equipment for their first rides, they may get frustrated and lose interest in skiing completely. If the beginners use the cross country skis according to the invention, they will not be frustrated but will experience pleasant feelings and will definitely enjoy their ride.
