EP2295120B1 - Ski, in particular cross-country ski with at least one device to prevent slipping backwards - Google Patents

Description

The invention relates to a ski, in particular a cross-country ski with at least one means for Rückleithemmung, as indicated in the preamble of claim 1 or 2, and a climbing or repelling aid as defined in the preamble of claim 30.

From the DE 27 52 397 A1 is a generic ski with a means for Rückgleithemmung disclosed, wherein the means for Rückgleithemmung is removed if necessary removably mounted in the outsole of the ski body. In this case, an elongated recess is provided in the ski sole, in which the means for Rückgleithemmung is required releasably attached. The elongated recess is formed by a U-shaped in cross-section element which is integrated in the ski structure and whose legs define the lateral boundary surfaces of the recess. In this U-shaped element is a substantially cuboidal element can be used, which has on its first flat side a brush or other Rückgleithemmendes means and on the opposite side has a smooth surface. The block-shaped element is designed as a turning part, so that either the anti-rebar surface or the smooth surface on the underside of the ski can be used. This turning part is connected via a positive connection with the skiseitigen, U-shaped member, if necessary, releasably connected. For this purpose, a respective longitudinal groove is provided on the inner surfaces of the two legs of the U-shaped element and on the two longitudinal side surfaces of the turning part is ever provided with these longitudinal grooves longitudinal projection provided in order to build a mutual, positive connection can. This positive connection in the manner of a tongue and groove coupling is produced as required by elastically resilient longitudinal walls of the turning part and released again. Depending on the orientation of the turnable about the longitudinal axis turning part relative to the ski body of the turning part provides a slip-back, which can be converted if necessary into a flush with the ski sole sliding surface, which can be waxed in the usual way. This prior art design has been found to be of little practicality.

The US 4,564,210 A describes a ski for the off-road, which is also suitable for climbs. This ski has at the bottom of a longitudinal slot whose width is less than half the ski width. In this longitudinal slot are with respect to the longitudinal direction the ski body arranged alternately sections of a fur-like climbing aid and Velcro sections. The hide-like climbing aid is permanently fixed in the longitudinal slot of the ski body by gluing it in or molded into it. The lower longitudinal edges of the ski body are formed by metal edges, which project from the underside of the ski body. A tread covering which improves the slipperiness of the ski body can be fastened between the metal edges and can be removed again as required. For this purpose, congruent aligned Velcro surfaces are formed on the back of the tread covering, which cooperate with the Velcro surfaces in the longitudinal slot of the ski body. Alternatively, the tread covering can be releasably secured to the ski base via magnetic action or via positive elements, such as snap elements or tongue and groove elements, as needed. This embodiment has been found to be of little practicality. In addition, the Velcro surfaces, magnets or snap connection with removed sliding or tread covering, ie with activated climbing aid, impaired or worn in the medium term.

The CH 244 368 describes a ski body on the underside of a raceway groove is provided which has coupling members for positive connection with corresponding coupling members on a climbing skin. In particular, the raceway groove can be formed by a rail element, whose projections or recesses interact with a corresponding form-fit element on a reverse-inhibiting climbing skin. The handling of this as needed mountable or removable slip-back protection is reasonable only for a person or group of users with sufficiently high skill.

From the WO 2004/064949 A1 a ski body is known, on whose running surface a back-hemming fur strip can be fastened by gluing. In order to avoid unintentional detachment of the ski tip facing the front end of the fur strip, spoiler or Klemmanordnungen are provided, with which the front end portion of the climbing skin can be hung and clamped in a recess in the tread. Thus, although a reliable connection between the climbing skin and the ski body can be created, but the corresponding spoiler or clamping arrangements cause increased cost and manipulation effort.

Also from the DE 20 2005 010 571 U1 is a on the tread of a ski aufklebbarer fur strips known that serves as a repellent or climbing aid. At skispitzenseitigen end of this fur strip a covering this end plate is provided, which is firmly connected to the fur strip and the free end protrudes beyond the skispitzenseitige end of the fur strip. This front plate in this case represents a spoiler or deflector element in order to avoid inadvertent detachment from the tread during use of the ski as possible. The handling of sticky fur strips on the backside is difficult and requires some practice. In addition, only in the presence of sufficiently dry or pretreated treads a good adhesion between the climbing skin the ski body can be achieved.

The WO 99/28007 A1 describes a ski-like gliding device which is composed of several individual parts, in particular a front, a middle and a rear part. The middle part takes on the top of the binding device for a sports shoe. At the front end of the middle part is the front part and at the rear end of the middle part, the rear part is positively fastened. A longitudinally elastic climbing skin is connectable to the ski tip side end of the front part and to the end remote from the middle part of the rear part. The longitudinally elastic climbing skin prevents unintentional decoupling of the three Gleitgeräteteile and provides a slip-back for walking on slopes.

The EP 1 787 692 A2 and the AT 008 739 U1 disclose skis, in particular touring skis, in which the climbing skin is releasably secured by means of at least one permanent magnet. The front ends of the climbing skins extend into the upwardly rising portion of the ski scoop, so that they are positioned elevated with respect to the snow background. The risk of detachment of the relative to the usual direction of movement, the front end of the climbing skin of the ski body is therefore marginal. In addition, a generously dimensioned fastening means for the front end of the climbing skin can be carried out by this climbing skin ending in the raised blade section. The climbing behavior of such skis is usually satisfactory due to the running over the entire ski length climbing skin. Its sliding behavior, in particular during the overcoming of intervening flat pieces or slope sections is, however, unsatisfactory. The handling of the shapely or unstable climbing skin requires practice and some skill. In addition, the respective assembly and disassembly operations are relatively complex or time consuming.

Also in the EP 1 882 502 A2 is a ski, especially a touring ski, and discloses a detachably connected climbing skin. The climbing skin is detachably attached directly to the underside of the sliding lining of the ski, wherein it is magnetically connectable to the ski. For this purpose, a magnetic film or layer can be integrated in the ski. The climbing skin comprises ferromagnetic means, such as woven, metallic threads or wires. It was also proposed to sew several flat magnets into the climbing skin. Also, this embodiment is less practicable in terms of handling and there is also the risk of snow accumulation between the climbing skin and the ski body and also with full-surface, magnetic interaction between the climbing skin and the ski body and subsequently the problem of gradual detachment of the climbing skin. In addition, the integration of magnetically active films or layers in the ski construction is technically problematic or costly. Furthermore, the handling or attachment of the formflexiblen climbing skin in practice is problematic for many people, especially if due to cold wearing gloves is required. In addition, the proposed climbing skin with woven, metallic threads or sewn flat magnet is relatively expensive.

The FR 2 792 213 A1 describes a ski, in particular a touring ski, which has an outsole designed as a turning part. The first flat side of the outsole has a climbing skin, while the opposite flat side is designed as a sliding coating. This turning part extends almost over the entire length and width of the ski body. In the two longitudinal side walls of the outsole each groove-like depressions are formed, which are to be offset with mutually facing projections on the inner sides of the control edges of the ski in positive engagement. To selectively activate the climbing skin or the sliding surface of the outsole, the blade portion of the ski body fold down and push the outsole with appropriate orientation, starting from the blade portion towards the ski end, on the lateral projections on the control edges, so that a positive connection between the ski body and the outsole is built. In addition, the outsole is secured by bolt connections in the blade area against displacement in the ski longitudinal direction. Furthermore, magnets may be provided with which the central portion or the central portion of the outsole is additionally connected to the ski body is bound. This prior art design has little practicality. In addition, the production of such a ski body is technically complex and generally relatively expensive. The threading or making the form-fitting connection between the ski body and the reversible outsole is also time-consuming and can be a long-term jam-free longitudinal guide between the outsole and the ski body can not be guaranteed. In addition, this running as a turning part outsole is connected to the ski body only if it extends at least to the tip of the ski or runs over the entire longitudinal extent of the ski, otherwise threading the outsole is not possible in the skikörperseitigen guide rails.

The US 5,292,147 A describes a generic ski, especially a cross-country ski, with a recess in the tread, in which a fastened on a support plate means for Rückgleithemmung can be used. The support plate is held by friction or latching in a downwardly open housing which is fixedly secured in the Laufflächenausnehmung. According to the drawings (FIGS. 16a, 16b), this support plate can be slidably inserted normal to the base surface of the recess. As an alternative to this frictional connection or latching or snap connection, it has been proposed to provide a form-fitting groove / tongue connection (FIGS. 17a-17c), wherein an insertion or threading operation into the recess on the ski side or into the lateral grooves of the recess ski-side recess a reliable mounting of the support plate to be achieved. Both the frictional coupling, the snap connection, as well as the positive coupling by means of tongue and groove elements is not practical or under adverse environmental or operating conditions unsatisfactory.

The present invention is based on the object to provide a ski, especially cross-country skis, whose means for Rückgleithemmung as easy as possible attachable or interchangeable or renewable and which nevertheless a reliable, secured against unwanted self-detachment securing the Rückgleithemmenden agent on the tread of the ski body allows. Another object is to provide a corresponding climbing or kicking aid.

This object of the invention is achieved by a ski, in particular a cross-country ski, with at least one means for Rückgleithemmung, which in relation to the ski longitudinal direction in the middle section, if necessary attachable climbing or kicking aid comprising at least one fur- or brush-like or a scale profile-like Rückgleithemmer on a comparatively rigid and dimensionally stable support member which is fastened in an elongated, running in the ski longitudinal recess in the tread of the ski, if necessary, removably attached, wherein the support member is slidably inserted into the recess in the vertical direction to the base surface of the recess and facing away from the coat or brush-like or scissors-like side of the support member has at least one first magnetically active surface, which with at least one further magnetically active surface at the bottom of the recess in and out of magnetic attraction is displaceable, or wherein the support member is slidably inserted into the recess in the vertical direction to the base surface of the recess and the fur or b Brush-like or facing away from the scale profile-like Rückgleithemmer side of the support element has at least one first adhesive or Velcro surface, which is displaceable with at least one further adhesive or Velcro surface at the bottom of the recess in and out of contact or engagement. It is further provided in each case that the support member is elastically compressible or shortened with respect to the longitudinal direction and is urged in the recess inserted state with elastic bias against a wall surface on at least one front end of the recess

A resulting from the subject invention according to the features of claim 1 or 2 advantage lies in the fact that the structural combination of a fur- or brush-like or a scale profile-like Rückgleithemmers with a support element a relatively easy or easy to handle module is created, which is particularly easy and can be reliably attached to a corresponding ski body as a climbing or kicking aid. An appropriate assembly process can be performed quickly and easily by laymen. In particular, no special training or exercise is required to make an assembly or disassembly, in particular an exchange of climbing or kicking aid in relation to the ski body can. The corresponding processes can be carried out intuitively and the function or the interaction of the corresponding components is self-explanatory even for technically unavailable persons or users. Despite the ease of use of this modular climbing or kicking aid in terms of their assembly and disassembly, it is sufficiently detachable connected to the ski body connectable. In particular, an undesirable self-detachment or a gradual Separation of the climbing or repelling help from the ski body are almost impossible. The forces occurring during use of the specified ski are transmitted primarily between the support element and the skiseitigen recess and received mainly by the support member or by the boundary walls of the recess. The adhesive or Velcro surfaces corresponding to one another have the primary task of maintaining or ensuring a planned relative position between the support element and the ski body or its recess. The detachment forces acting in the vertical direction relative to the running surface of the ski body during use of the ski can be easily absorbed by the additional magnetic or adhesive or Velcro surfaces. In particular, the vertical or separating forces acting on the modular climbing or kicking aid during the use according to the invention of the ski according to the invention are so small that the formed magnetic or adhesive or Velcro surfaces adhere to one another with sufficient holding force. A particular advantage is further that, in particular, a fur or brush-type Rückgleithemmer can be particularly firmly or detachably connected to the support element and said components can form a functionally reliable and comfortable to handle unit. In any case, a fur or brush-type Rückgleithemmer, which is to be mounted only on an adhesive layer directly on the tread of a ski, much more difficult to handle and with respect to unwanted detachment much more critical than the inventive design. In addition, it is advantageous that the optional attachment of a fur- or brush-like or a scale profile-like Rückgleithemmers on the tread of a designed as cross-country skis under certain snow conditions each represents a particularly advantageous, especially a particularly effective climbing or kicking.

Among other things, the holding force or the reliability of the connection between the climbing or repelling aid and the ski body is further increased by the measures according to the invention. Nevertheless, the handling, especially the assembly and disassembly process of climbing or repelling the ski body against the ski body continues to be done easily and quickly. Another advantage is that gap formation between the support element and the recess can be avoided and thus rattling or impact noise can be excluded during use of the ski. Furthermore, a gradual accumulation of snow or ice between the support member and the skiseitigen recess is avoided, so always a proper or planned relative position between the Rising or repelling help and the ski body is guaranteed. In addition, this increases the reliability of the connection between the climbing or repelling aid and the ski body, after snow accumulation, which would exert a driving or wedge effect, are avoided as possible.

Another advantage are the measures according to claim 3, as this unwanted separation or separation tendencies between the climbing or repelling aid and the ski body can be counteracted in a simple manner. In addition, the climbing or repelling aid is first positioned exactly with each assembly process relative to the ski body and only subsequently connected to this. Inappropriate connection positions or inaccurate alignments between the climbing or kicking aid and the ski body are thus excluded. In addition, an undesirable accumulation of snow or ice between the support member and the recess is held back, whereby gradual separation tendencies or deterioration of the sliding properties of the ski can be avoided.

By the measures according to claim 4, a slidable insertion and removal of the support element or the climbing or repelling aid is accomplished with respect to the skiseitigen recess. After at least the lateral longitudinal sections of the support element and the skiseitigen recess can slide past each other almost without resistance and no mutual latching or mutual positive fit is present, the mounting and demountability of the climbing or repelling the ski body is much easier or improved. The separation protection of the climbing or kicking aid in the vertical direction to the running surface of the ski body is accomplished primarily by the magnetic forces or by the adhesive or Velcro forces between the climbing or repelling aid and the ski body. Without the mentioned attracting or holding forces, the climbing or kicking aid would fall out of the recess in the running surface at the latest during the use of the ski.

By the measures according to claim 5, on the one hand, the handling of the climbing or kicking aid can be improved. In addition, this makes it possible in a simple manner, with fixed predetermined size of a ski-side recess, ie a recess with predefined length or width dimensions, depending on the dimensions or thickness of at least one boundary wall or in dependence of size or extent of at least block or plate-like extension to vary the characteristics and effectiveness of the modular climbing or kicking aid or adapt. In particular, depending on the size or the areal extent of the at least one boundary wall or of the at least one block or plate-like extension of the support element, the remaining effective area of the backhoe inhibitor can be easily adapted to the respective requirements or individual needs. Thus, a first climbing or repelling aid with relatively small-area anti-backlash effect can be replaced by another climbing or repelling aid with a comparatively larger, anti-backlash effect, and vice versa. The respective surface portion of the at least one boundary wall or of the at least one block or plate-like extension can have approximately the same sliding properties as that of the other tread surface of the ski body. Alternatively, the substantially plane-parallel to the running surface of the ski body extending surfaces of the boundary wall or the at least one block or plate-like extension also have a Rückgleithemmende effect, in particular scale or sawtooth-like profiles, or have microstructures to the climb or To be able to individually change the gliding ability of the ski body or to influence it if necessary. For this purpose, an existing climbing or kicking aid is merely to be replaced by another climbing or kicking aid with the desired characteristic module.

Another advantage is an embodiment according to claim 6, as a comparatively robust and easily manageable climbing or kicking aid is created after adverse damage can be kept behind especially in a fur or brush-like Rückgleithemmers. In particular, tearing off or detachment of back-inhibiting hairs or fibers is counteracted, especially in the edge section of a hide-like or brush-type back plate inhibitor. The circumferential boundary walls also provide protection against premature wear or worsening of the anti-rebar effect of the climbing or kicking aid. In addition, the manageability of a correspondingly formed climbing or pushing aid is improved.

By applying at least one of the measures according to claim 7, a robust climbing or kicking aid is provided which is easy to transport, easy to handle and long-term operational. In addition, this ensures that a separation between the climbing or repelling aid and the ski body always between the facing each other or associated Velcro is carried out and an unwanted detachment of the Velcro element is reliably avoided by the support element.

The measures according to claim 8, a particularly robust, modular climbing or repelling help is created, which even with high mutual connection or Velcro forces against the ski body in the longer term has no delamination.

By the measures according to claim 9, a reliable, if necessary, activatable and deactivatable connection between the modular climbing or kicking aid and the ski body is achieved. The procedure for connecting the corresponding components is intuitively recognizable and handling very simple. Optionally, even disassembly tools can be completely dispensed with. It is essential that solely by the holding or Velcro force of the corresponding Velcro surfaces a sufficiently strong and position-stable connection can be achieved. After the corresponding Velcro surfaces have a relatively small total thickness, the influence on the bending mechanical properties of the ski body is relatively low. In addition, a relatively small depth for the recess in the ski body is sufficient. Corresponding velcro surfaces are preferable to adhesive surfaces, since velcro surfaces are usable in the long term or long-term have a good adhesion and are less sensitive than adhesive surfaces.

Also advantageous is a development according to claim 10, since it can be increased in terms of their characteristics, the Rückgleithemmende effect of climbing or repelling aid in a simple manner and manner. In particular, the climbing or kicking aid can form at least one backward-inhibiting ramp or sawtooth shape on the tread of the ski in the state that has been secured according to the plan. This effect can be realized either by the orientation of the climbing or kicking relative to the tread of the ski and / or by appropriate shaping of the ski-side recess and / or the support element of the climbing or kicking aid, as in the claims 11, 12, 13 is marked.

Of advantage is also the embodiment according to claim 14, since a rear and / or front repulsive edge is created, with which or with which, depending on the particular requirements or individual wishes, the anti-backlash effect the climbing or kicking aid can be moved in the direction of the ski longitudinal axis forward or backward. Furthermore, the number of repulsion edges and thus the extent of Rückgleithemmung can be easily increased and decreased, so that a better adaptation to the particular conditions or the individual wishes is possible.

According to an embodiment as described in claim 15, a recess is provided in the ski body, the dimensions of which are sufficiently precise in order to be able to build as gap-free as possible a connection between the modular climbing or kicking aid and the ski body. In addition, a cutout ensures high reproducibility and the simplest possible and cost-effective production of the ski body. In addition, during the production phase, individual ski bodies can be produced or prefabricated in a simple manner without a cutout and structurally identical ski bodies with a milled recess can be produced as required by the milling in a subsequent or final production step. As a result, production-related and logistical simplifications can be achieved.

Also advantageous are the measures according to claim 16, since thereby in the running surface of the ski, a recess can be created with sufficient depth, without significantly weaken the strength-relevant lower flange of the ski body, in particular to belittle. In particular, this makes it possible to achieve or maintain an optimally optimal, in particular homogeneous course with regard to the bending characteristic of the ski body.

By the measures according to claim 17, the spacer layer those forces which act in the use of the ski transversely to the ski longitudinal direction, but especially in the ski longitudinal direction, and act between the climbing or repelling aid and the ski body can be reliably absorbed. Thus, signs of wear or material compression in the tread surface, in particular at the boundary edges around the recess, be kept behind.

By the measures according to claim 18, a Skisohlenkonstruktion is provided in which the outer side surfaces of the spacer layer form lower sections of the side surfaces of the ski body or so-called side cheek elements of the ski body. On the one hand As a result, the production of the ski body is kept as simple as possible. In addition, a reliable connection is achieved in the relatively narrow, remaining longitudinal or edge sections on both sides of the recess, in particular a high-strength bond between the tread covering and the spacer layer allows.

Another advantage is an embodiment according to claim 19 and / or 20, characterized in that the support element in the inserted state in the recess exerts a bias against the boundary surfaces of the recess, so that an improved connection or a longer-term maintenance of the scheduled connection between the corresponding Velcro or adhesive surfaces can be achieved. In particular, in this way the end sections and / or the middle section of the support element in the state connected to the ski body can be pressed with constant preloading force against the respectively assigned surface sections of the recess, so that an undesired lifting of the hook and loop connection can be counteracted. In addition, a possible play or wobble-free connection between the climbing or repelling aid and the ski body can be achieved.

Also, by the measures according to claim 21, the climbing or kicking aid, in particular its support member, are secured in a simple manner against unwanted detachment relative to the ski body. In particular, when the recess has an undercut on at least one front end, in which a corresponding extension of the support element can be inserted in a form-fitting manner, the quality of connection between said elements can be significantly increased. In connection with an arcuate in the state of rest or biased in the installed state support element, the connection quality can be increased again without structurally complex security measures or time-consuming and complicated operations are required in terms of handling.

By at least one of the measures according to claim 22, a magnetic attraction between the climbing or kicking and the recess in the ski body can be created, which is sufficient to withstand the forces or separation forces occurring during use of the ski can. In particular, by attaching at least two magnetically attracting permanent magnets or by attaching at least one permanent magnet, which with at least one ferromagnetic Material or with at least one magnetically attractable element in interaction can be set, a reliable, yet easy or quickly detachable connection between the climbing or repelling aid and the ski body are created.

According to the advantageous embodiment according to claim 23 or 24, the at least one magnetically attractable, ferromagnetic material or the passive element is formed on or in the support member, while the magnetically active element, in particular the at least one permanent magnet is provided on the ski side. This allows the creation of the most cost-effective systems possible. In particular, different types or types of climbing or repelling aids can be created relatively inexpensively and purchased relatively inexpensively by the end user. The comparatively more expensive permanent magnets are assigned to the skis and thus financed by an end user only once, after usually only one ski body is required, which can be better adapted to different conditions of use in the episode by means of various climbing or repelling aids.

Especially when the support element is arcuate executed in the initial state and biased in the installed state, or when the support member has a longitudinally arcuate adhesive or Velcro surface, the development according to claim 25 facilitate assembly or disassembly relative to the ski body. In addition, an exact, relatively tension-free connection between the support element and the ski body can be created thereby. In particular, sections can thereby be created which represent free-running compensation zones between the support element and the ski body or its recess.

Also, by the measures according to claim 26, a sufficiently reliable and easy to build and detachable connection between the support element of the climbing or repelling aid and the sliding board body can be created. A frequent connection and solubility is achieved by known per se adhesive layers, as they also serve for attachment of standard climbing skins on tread coatings, easily.

By the measures according to claim 27 it is ensured that the applied on the support member, permanently tacky and non-hardening adhesive layer, a possible strong adhesion can build adhesive connection with the ski body, in particular with the base of the recess.

Finally, an embodiment according to claim 28 is advantageous, as a result, the Rückgleithemmende effect of a fur or brush-like or a scale-like climbing or repelling aid can optionally be activated and deactivated or attenuated. In particular, the anti-buckling effect of the climbing or kicking aid can, if necessary, also be reduced to a sliding-inhibiting effect, i. be converted into a braking action for the ski body during forward or downward movements. Especially for beginners or persons at risk of injury, driving on slopes or overcoming hard or icy sections of the route can be made easier or more pleasant. Above all fur- or brush-like or scaly profile-like climbing or repelling aids usually have a unidirectionally acting Rückgleithemmung so that they hardly develop a braking effect in opposite direction of use or in reverse relative movement with respect to the ground and have relatively good sliding properties. In particular, the usual, alternating climbing and sliding effects of a ski, in particular a cross-country ski, can be reversed or reversed as needed.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

In the Fig. 1 to 3 there is shown a ski 1 which has at least one means for inhibiting backward sliding movements. Such a ski 1 belongs to the genus of so-called cross-country skis or cross-country skis, which are provided on the one hand for gliding and on the other hand for the easiest possible to manage slopes. The specified ski 1 can also be designed as so-called touring or mountaineering skis. That is, the ski 1 disclosed herein, on the one hand, as a cross-country skis for groomed or unlubricated terrain, but can also be designed as a ski 1 for the exercise of mountain sports.

Fig. 1 shows an embodiment of a generic ski 1, in particular a cross-country ski, in a conventional manner in the middle section, ie in the binding mounting portion, a defined bias height 2 has. By this Vorspannhöhe 2 of the central longitudinal portion of the underside or the tread of the ski body in the unloaded state or in load conditions below a predetermined threshold to a planar surface is distant. This Vorspannhöhe 2 is relatively larger in cross-country skis or in so-called cross-country skis, as in so-called touring or Mountaineering skis. In touring or mountaineering skis, the longitudinal section in which there is a means for Rückgleithemmung is usually greater than in cross-country skiing or cross-country skis, where this Rückgleithemmende longitudinal section can extend over the entire length of the tread of the ski body ,

With respect to the ski longitudinal direction, in a cross-country ski, which is the preferred type of ski, at least one means for back-hemming, i.e. at least in the central portion 3 of the ski body, is provided. a Rückgleithemmer 4 is formed. In particular, a Rückgleithemmender section 3 is provided at least in the region of a binding mounting zone or a shoe contact portion on the underside of the ski basic body, which is formed by at least one Rückgleithemmer 4 or at least one Rückgleithemmer 4 includes. This Rückgleithemmende section 3 usually extends in about more than a third of the ski length. Optionally, this section may also be made shorter or run almost over two thirds of the ski length. In any case, the Rückgleithemmende section 3 in relation to the total length of a ski, especially a cross-country ski, partially executed.

The Rückgleithemmer 4 is required, releasably secured to the underside of the ski body. According to an advantageous embodiment variant of the Rückgleithemmer 4 is executed fur or brush-like. In particular, the effective surface of the Rückgleithemmers 4 may preferably be designed as a so-called climbing skin, which causes in a first direction of movement, in particular in a conventional direction of travel of the ski 1, the lowest possible sliding resistance to the ground and in a second, opposite thereto Direction provides the highest possible braking or Verkrallungswirkung against the ground, so that this Rückgleithemmende section 3 can act as a slip-back protection or as a climbing or kicking 6.

Preferably, the Rückgleithemmer 4 is formed by a fur-like element with a plurality of hairs or fibers. In order to increase its unidirectional braking or inhibiting effect, these hairs or fibers are systematically ordered, and they can also be slightly inclined relative to the ground or made angled.

This in itself relatively pliable or little dimensionally stable fur or brush-like Rückgleithemmer 4 is arranged on a comparatively rigid and dimensionally stable support member 5. By this support member 5, on which, for example, the fur or brush-like Rückgleithemmer 4 is fixed, a flat or elongated shape of the Rückgleithemmers 4 is ensured. That is, the fur or brush-type backrest damper 4, by virtue of its connection with the support element 5, substantially retains a stretched, strip-like shape with defined dimensions. Consequently, the support element 5 can also be referred to as a support body for the relatively flexible, fur or brush-type backlash hammers 4. This combination element consisting of the fur-like Rückgleithemmer 4 and the support member 5 is also in its removed from the ski 1 state largely dimensionally stable or dimensionally stable, this combination element has an approximately strip-like or plate-like basic shape.

The fur or brush-like Rückgleithemmer 4 is preferably permanently connected to the support member 5, in particular glued, welded, sewn, riveted and / or positively connected. The fur or brush-like Rückgleithemmer 4 and the support member 5 thus form an integrally formed climbing or kicking 6, which is, if necessary, releasably connected to the underside of the ski 1. In the state connected to the ski 1, the climbing or kicking aid 6 is at least partly accommodated in an elongated recess 7 running in the longitudinal direction of the ski 8 in the running surface 8 of the ski 1 or at least partially inserted therein.

It is expedient if the support element 5 for the fur or brush-type Rückgleithemmer 4 with respect to the Skilängs- and Skiquerrichtung essentially free of play in the recess 7 can be inserted. This means that the support element 5 is positioned and received without play, or at least approximately free of play, transversely to the ski longitudinal direction and in the longitudinal direction of the ski through the boundary walls or boundary surfaces of the recess 7. In order to avoid that the climbing or kicking 6, that is, the Rückgleithemmer 4 in combination with the support member 5, accidentally falls from the recess 7 or gradually dissolves from the recess 7, the side facing away from the Rückgleithemmer 4 side of the support element 5 with provided with a further adhesive or Velcro surface 10 at the bottom or base 11 of the recess 7, if necessary, in and out of contact or intervention can be brought. A holding force of the adhesive or Velcro surfaces 9, 10 can be dimensioned such that the user can make a preferably tool-less assembly and disassembly of the climbing or kicking 6 relative to the ski body. The modular climbing or kicking aid 6, which comprises at least the support element 5 and the backlash inhibitor 4 mounted thereon, is thus by the action of corresponding Velcro surfaces 9, 10, or alternatively by the action of adhesive surfaces which can be brought into contact with each other, with respect to the forces occurring on the use of the ski 1 sufficiently tear-off or detachment secured in the recess 7 on the underside or in the tread 8 of the ski body.

The holding force or connection security of the climbing or pushing aid 6 within the recess 7 is achieved at least partially by the bonding forces between the adhesive or Velcro surfaces 9, 10. According to an advantageous development, the holding force between the climbing or kicking 6 and the skiseitigen recess 7 can be increased in part by clamping forces between outer surfaces of the support member 5 and associated boundary or wall surfaces of the recess 7. In this case, a kind of clamping or press fit or a backlash-free sliding between the support element 5 and the recess 7 is completely sufficient, so that an additional form-fitting connection, e.g. in the manner of a tongue and groove connection, between the side surfaces of the support element 5 and the wall surfaces of the recess 7 can be omitted entirely.

The predominant portion of the anti-rebar effect of the climbing or kicking aid 6 is achieved by the undirectional braking effect or by the Verkrallungseffekt the Rückgleithemmers 4 against the respective substrate, especially against snow or ice. In particular, when the central portion 3 as fully as possible with the Substrate comes into contact, a high level of repelling force against the ground can be achieved in order to support the most impulsive or efficient repulsive movement in the direction of the usual direction of travel.

In order to further increase the Rückgleithemmung or the repelling effect of the modular climbing or repelling 6, in the usual direction of travel - arrow 12 - related, rear end face 13 of the support member 5 may have at least one transverse edge 14 which an additional Verkrallung or a additional, positive engagement of the ski 1 relative to the ground made possible by at least one transverse edge 14 of the support element 5 in the recess 7 as planned inserted state of the climbing or repelling 6 at least one repelling edge 15 against the ground, especially against snow surfaces forms, like this best off Fig. 2 is apparent.

In order to achieve the at least one effective against a snow ground repelling edge 15, the Rückgleithemmende underside of the Rückgleithemmers 4 or its support member 5 may be aligned with respect to a longitudinal section through the ski 1 at an angle to the tread 8 of the ski 1 in a simple manner so that at least in relation to the usual direction of movement - arrow 12 - rear end portion of the Rückgleithemmers 4 or the support element 5 defines at least one repelling edge 15 relative to the ground. To achieve this in the longitudinal section through the ski body sawtooth-like contour on the underside of the ski 1, the support member 5 may be formed wedge-shaped in longitudinal section in a simple manner, as in Fig. 2 was illustrated schematically and exemplified.

According to a further embodiment, a front, lower end edge 16 of the support element 5 and the Rückgleithemmers 4 may be positioned closer to the Skikern with respect to the usual direction of travel - arrow 12, than the rear, lower transverse edge 14 of the support element 5 and Rückgleithemmers 4. Accordingly, by a wedge-shaped in longitudinal section training the climbing or kicking 6 and / or by a wedge-shaped depth profile of the recess 7, a rear repelling edge 15 and / or a front repelling edge 17 are created. The front repelling edge 17 is formed by the front, lower boundary edge 18 of the recess 7. In particular, in the transition section between the front end of the climbing or repelling 6 and the tread 8, the Abstoßkante 17 may be formed. This front repelling edge 17 can in turn be created by a wedge-shaped contour in longitudinal section of the climbing or repelling aid 6 and / or the recess 7.

In summary, it should be noted that by an angular orientation of the climbing or repelling aid 6 in relation to the tread 8 of the ski body either only a front Abstoßkante 17 or only a rear Abstoßkante 15 or both a rear, and a front Abstoßkante 15, 17 can be formed like this in Fig. 2 was exemplified. Depending on the configuration, a rear transverse edge 14 of the support element 5 or of the return track inhibitor 4 with respect to the usual direction of travel - arrow 12 - is raised or protruding relative to the running surface 8. Alternatively or in combination, the front boundary edge 18 of the recess 7 and the recess 7 receiving tread over the front, lower end edge 16 of the support member 5 and the Rückgleithemmers 4 project down or form a gradation and so the rückbeleithemmende, front Form repelling edge 17.

A further embodiment provides that the rear end portion of the climbing or pushing aid 6 is flush with the running surface 8 and that only the front boundary edge 18 of the recess 7 defines a repelling edge 17, as shown in FIG Fig. 3 is exemplified. However, depending on requirements or depending on the snow conditions, it is also possible to align the effective underside or the so-called grip surface of the climbing or kicking aid 6 parallel to the contact plane of the ski 1 or parallel to its running surface 8, as shown in FIG Fig. 6 or Fig. 9 has been illustrated schematically.

According to an advantageous development, the climbing or repelling aid 6, in particular its support element 5 together with the unidirectionally acting Rückgleithemmer 4, with respect to a perpendicular to the underside extending axis by 180 ° reversible running, so that a certain end portion of the climbing or repelling aid 6 in Reference to the usual direction of travel - arrow 12 - the ski 1 can optionally represent the front and the rear end of the climbing or kicking 6. Thus, in a simple manner, as needed activation and deactivation or attenuation of Rückgleithemmenden effect of the underside of the climbing or repelling aid 6 allows. The recess 7 is designed such that they receive the climbing or repelling aid 6 with respect to both orientations can. For this purpose, the recess 7 and the climbing or repelling 6 is formed symmetrically with respect to a transverse division or median plane.

If in this case the climbing or repelling aid 6, in particular the support element 5 and the recess 7 are each wedge-shaped with respect to a longitudinal section through the ski 1 or respectively have support extensions and recesses, in a simple manner at least one sawtooth-like ramp or the at least one repelling edge 15, 17 are selectively activated and deactivated. In particular, this can be done depending on the need or requirement, an angular orientation of the underside of the climbing or kicking 6 in an at least approximately parallel and stepless alignment of the underside of the climbing or repelling 6 in relation to the tread 8, and vice versa. This is possible as required or as desired by the user as well by simply turning the climbing or kicking 6 by 180 ° with respect to a perpendicular to the underside extending axis and by re-insertion into the skiseitige recess 7.

As in Fig. 4 9 or 9, it is therefore also possible or it may be expedient that the support element 5 or the Rückgleithemmer 4 during its properly inserted into the recess 7 state flush with the running surface 8 completes.

According to an advantageous measure, however, the Rückgleithemmer 4, in particular a fur or brush-like climbing aid, projecting with respect to the tread 8, ie have a projection 19 and therefore protrude towards the tread 8 in the downward direction, as in Fig. 4 has been shown schematically. This supernatant 19 is usually in a range between 0.2 to 4 mm.

In Fig. 5 is an advantageous expression or modification option for the generic ski 1 illustrated. Here, the climbing or kicking 6 is provided as a removable module relative to the ski body. As a result, a specific embodiment of a climbing or kicking aid 6 can be replaced as required by at least one climbing or pushing aid 6 ', 6 ", which is different in its effect and / or design However, the individual support elements 5, 5 ', 5 "have structurally different or in their In particular, a first backrest inhibitor 4 may be formed like a hide or a brush, and another, alternatively usable, backrest inhibitor 4 'may have a known climbing aid profiling 20. This climbing aid profiling 20 may be made into a plastic layer 21 As is conventionally also used for the actual running surface covering of the ski body, it may be cut or milled in. In a manner known per se, this climbing aid profiling 20 comprises on the underside of the modular climbing or kicking aid 6 'with respect to a longitudinal section through the plastic layer 21'. The plastic layer 21 ', which is provided with a corresponding flake or step profile or with a microstructuring, is permanently connected, in particular permanently glued, to the support element 5' while the plastic layer 21 'is preferably made of polyethylene ylen is its support member 5 'is preferably formed by polyamide.

A further embodiment of the modular climbing or kicking aid 6 "provides that its underside is formed by a plastic layer 21", which essentially corresponds in terms of basic properties to the plastic layer for forming the running surface 8 of the ski 1. The plastic layer 21 "can have a layer of climbing wax 22 on its effective underside and thus form a further embodiment variant of a climbing or repelling aid 6". However, if no climbing wax 22 is applied to the plastic layer 21 ", then the plastic layer 21" can also contribute to improving the sliding behavior of the ski 1. Thus, the climbing or kicking aid 6 "designed as a replacement module can if necessary also contribute to improving the sliding behavior of the ski 1. In particular, a ski 1 intended for classic cross-country skiing can thereby be easily replaced by replacement of the climbing or kicking aid 6 as required into a so-called skating-ski, and vice versa.

It is essential that a plurality of, if necessary, interchangeable, modular lifting or kicking 6, 6 ', 6 "is present, which optionally or as needed in the recess 7 of a ski 1 are used and by means of the first adhesive or Velcro surface 9 on the support element 5, 5 ', 5 "with a corresponding adhesive or Velcro surface 10 on the base 11 of the shape and dimensions largely compatible, skiseitigen recess 7 in and out of contact or intervention are displaceable.

According to the execution of the Fig. 6, 7 is the support member 5 for the Rückgleithemmer 4, in particular for a fur or brush-like Rückgleithemmer 4 trough or trough-like design. Accordingly, the support element 5 comprises a base plate 23 with at least two lateral boundary walls 24, 25. Preferably, the support element 5 is designed like a trough, so that it also includes boundary walls 26, 27 in the front and rear end portion. Between at least two opposing boundary walls 24, 25 and 26, 27, the receiving area for a Rückgleithemmendes means, in particular for the fur or brush-like Rückgleithemmer 4 is defined. The respective boundary walls 24, 25 and / or 26, 27 in the outer edge portions of the support element 5 increase inter alia the tear resistance of the Rückgleithemmers 4 relative to its support member 5. In particular, this is the security against unintentional detachment or shearing the Rückgleithemmers 4 of the support element 5 improved.

At least one end boundary wall 26, 27 of the support element 5 can also be embodied as a block-like or plate-like extension 28, 29. This at least one block or plate-like extension 28, 29 improves the handling of the support element 5. In addition, by a spoiler-like course of the background of the underside of this extension 28, as best of Fig. 6 it can be seen that the interaction of the climbing or pushing aid 6 with the ski 1 is improved. Thus, the at least one frontal extension 28, 29 with respect to a longitudinal section through the support member 5 form an angle to the running surface 8 extending bevel 30 through which the Rückgleithemmer 4 nearest end portion of the extension 28 with respect to the tread 8 of the ski raised or projecting is trained. As a result, the support element 5 can form a front repulsive edge 17 which increases the anti-backlash effect of the climbing or repelling aid 6 or of the ski 1. For this purpose, the block or plate-like extension 28 may be wedge-shaped or sawtooth-shaped in longitudinal section, wherein the repelling edge 17 is defined by a steep boundary edge of the recess in the support element 5, in which the fur or brush-like Rückleithemmer 4 is at least partially accommodated.

The in relation to the usual direction of travel - arrow 12 - the ski 1 rear extension 29 may also be designed as a stepped ramp with respect to a longitudinal section to the Rückgleithemmemmende effect of the support element 5 and the climbing or repelling 6 further increase, as in Fig. 6 was exemplified and shown schematically.

On or in at least one extension 28, 29, at least one disassembly aid 31 may be performed, with which a detachment of the climbing or repelling aid 6 is facilitated by the ski body. This dismantling aid 31 is preferably formed by a groove-like depression or by an undercut in order to facilitate, with the aid of a tool, for example a screwdriver, a detachment of the climbing or kicking aid 6 or of the support element 5 from the ski body. In particular, by using an auxiliary tool in conjunction with the dismantling aid 31 on the support element 5, a quick and effortless release of the support element 5 from the skiseitigen recess 7 can be achieved. This disassembly aid 31 can also improve the Rückgleithemmende effect of the climbing or pushing aid 6 by appropriate undercuts or by step formations, as the Fig. 6, 7 can be clearly seen. In particular, the dismantling aid 31 may be designed as a wedge-shaped recess 32 in longitudinal section, with respect to the usual direction of travel - arrow 12 - front edge 33 at least one repelling edge 15 against the ground, especially against snow or ice forms. In plan view of the support member 5 and in view of the ski 1 from below - according to Fig. 7 - The recess 32 in the support member 5 may also be wedge-shaped or funnel-shaped, in order to achieve a compression of accumulating snow therein and thus an improvement of the repelling effect or an improved Verkrallungseffekt against a snow background. The wedge or funnel shape of the recess 32 causes during the repulsion phase compression of accumulating in the recess 32 snow, whereby its compactness or strength is increased and the corresponding compressed snow wedge can provide higher abutment forces and thus can absorb higher repulsive forces without destroying or to be moved. Of course, it is also possible to provide a plurality of such wedge-shaped or funnel-shaped recesses 32 on the underside of the support element 5. At least one of these, for example, row or column-like recesses 32 may, as described above, also be used as a disassembly 31, the use as a disassembly 31 is not mandatory and the function of an additional repelling aid or Rückgleithemmung be provided and implemented alone can. According to an advantageous embodiment, the support member 5 is formed elastically compressible or shortened with respect to the longitudinal direction. This elastic compression path can be a few tenths of a millimeter up to a few millimeters. Alternatively or in combination with this, the support element 5 can have an elastically yielding compensation element 28a on at least one front end, which can also be formed by at least one end extension 28 of the support element 5. The elastic compression or shortenability of the support element 5 or the entire climbing or kicking aid 6 is expedient to support the support element 5 with increased tear resistance or holding force as planned in the recess 7. By a certain length or width excess of the support member 5 in comparison to the recess 7 namely the support member 5 can push with elastic bias against at least one end face of the recess 7 and thus increase its separation strength. In addition, this undesirable accumulation of snow or ice between the outer boundary surfaces of the support member 5 and the boundary surfaces of the recess 7 is held back. For this purpose, the support member 5 may be formed in total or only in sections of an elastomeric plastic.

Primarily, however, the holding force of the support element 5 within the recess 7 by the corresponding adhesive or Velcro surfaces 9, 10 applied. Preferably, the support element 5 is held by means of corresponding Velcro surfaces 9, 10 positioned within the recess 7. The first Velcro surface 9 on the side facing away from the Rückgleithemmer 4 side of the support member 5 is formed by a first Velcro element 34, which is permanently glued to the opposite of the Rückgleithemmer 4 side of the support member 5, sewn, welded or riveted. In particular, a permanent, tear-resistant connection between the first Velcro element 34 and the rear flat side of the support element 5 is provided. Preferably, the first Velcro surface 9 is formed by a strip-shaped Velcro element 34. At the back of the Velcro element 34, the support element 5 is attached. The support element 5 is preferably made of plastic, wherein the Velcro element 34 can be attached cohesively and / or can be injection-molded in a form-fitting manner. The further Velcro surface 10 corresponding to the first Velcro surface 9 at the base 11 of the ski-side recess 7 is formed by a further Velcro element 35 corresponding to the first Velcro element 34.

According to an advantageous embodiment, the support member 5 may also be designed in several parts or mehrgliedrig to affect the bending stiffness of the ski body as little as possible or to facilitate handling, in particular the disassembly with respect to the skiseitigen recess 7. In multi-part or multi-membered design, the support element 5 or the climbing or repelling 6 is performed caterpillar or ribbon-like.

In the illustrated embodiment according to the Fig. 6, 7 the recess 7 is formed by a cutout whose spatial dimensions approximately correspond to the dimensions of the support element 5. This means that the length, width and possibly also the depth dimensions of the cutout or recess 7 approximately correspond to the length, width and possibly the thickness dimensions of the support element 5. A thickness or thickness 36 of the strip or plate-like climbing or kicking aid 6 is at least 2 mm. A practicable thickness 36 ranges between 2 and 6 mm. The thickness 36 of the climbing or kicking aid 6 is thus usually greater than the thickness of the running surface 8 forming tread surface of the ski 1. A depth 37 of the recess 7 is thus usually greater than a thickness or thickness of the tread 8 forming tread of the ski 1. In order to reduce the risk of delamination of the ski structure or to avoid a critical weakening of a strength or stiffness-relevant lower flange 38 of the ski 1, an additional spacer layer 39 may be implemented in the ski construction. At least the base of the recess 7 is then formed by the spacer layer 39. The spacer layer 39 is arranged between the rear side of a running surface 8 forming the tread surface 41 facing a ski core 40 and the at least one strength-relevant lower flange 38 of the ski 1. The recess 7 is thus partially defined by the material of the spacer layer 39, that is, the spacer layer 39 forms a portion of the recess 7 and sections of wall surfaces 42, 42 'of the recess 7 are formed by the spacer layer 39. The spacer layer 39 distances the tread surface 41 of the ski body from the strength-relevant lower flange 38 of the ski body. The spacer layer 39 is preferably made of plastic and allows a high-strength connection, in particular bonding on the one hand with the elements of the lower belt 38 and on the other hand with the plastic of the tread 41. The Skikern 40 is formed for example of a honeycomb material or PU foam.

How best to look Fig. 5 it can be seen, the spacer layer 39, at least within the ski longitudinal section, in which the recess 7 is formed, have a width 43 which corresponds to the width of the running surface 8 forming tread 41. A width 44 of the climbing or kicking 6 and the supporting element 5 and an associated width of the recess 7 is expediently more than 70%, preferably about 90% of the width 43 of the tread 8. Alternatively, the width 44 of the climbing or kicking aid 6 also correspond approximately to the width 43 of the tread lining 41. This means that the Rückgleithemmer 4 can also be formed over the entire ski width and, accordingly, can develop a high anti-backlash effect. A usual width 44 of the climbing or kicking 6 amounts to 20 mm to 50 mm, preferably to about 30 mm. A practicable length of the climbing or kicking 6 is between 300 mm and 600 mm, preferably in about 400 mm. The longitudinal central portion of the climbing or kicking 6 is positioned in relation to the longitudinal direction of a cross-country ski in approximately congruent with the coupling member of a cross-country binding, as is apparent from Fig. 1 is schematically visible. The climbing or kicking aid 6 extends over a portion of the length of a cross-country skis, which is less than 50%, preferably about 20-25% of the ski length.

In the Fig. 8, 9 is a further embodiment of a structural combination of a ski 1, in the concrete of a cross-country ski, illustrated with a modular, as needed interchangeable climbing or repelling 6. Again, the climbing or kicking 6 extends to the underside of the ski body only within a short range to the Schuhaufstands- or binding mounting portion. That is, the climbing or repelling aid 6 does not reach into the blade portion and also not into the rear end portion of the ski body.

Here, the side facing away from the Rückgleithemmer 4 of the support member 5 and the climbing or repelling 6 in the removed state of the recess 7, that is, during the rest or inactive state of the support member 5, with respect to the longitudinal direction of the groove, in particular concave curved , In particular, the rising or pushing aid 6 or its support element 5 has an arcuately extending rear side, so that it is virtually banana-shaped in the unmounted state or not inserted into the recess 7, as can be seen from FIG Fig. 8 is exemplified. In this context, at least one of the hook-and-loop surfaces 9, 10 expediently extends only over partial sections, in particular only over the central longitudinal section of the support element 5 and / or the base of the skiseitigen recess 7, as the Fig. 8, 9 can be seen by way of example. In the alternative embodiment of adhesive surfaces which can be displaced in mutual contact, they likewise extend only over a partial section, in particular only over the central longitudinal section of the support element 5 and / or the recess 7. The distal end sections of the recess 7 and / or of the support element 5 have no adhesion - or connecting means on. This facilitates the assembly process and increases the quality of connection between the climbing or kicking 6 and the ski body.

The support element 5 may have on at least one of its front ends a projection or an extension 45, 46 or alternatively a recess or recess, which or with at least one corresponding undercut or depression 47, 48 or with at least one corresponding extension in the Recess 7 is displaceable in and out of positive engagement. An advantageous shaping is when at each of the front ends of the support element 5 projections 45, 46 are formed, which can engage in the inserted into the recess 7 state of the support element 5 in undercuts or depressions 47, 48 in the region of the front ends of the recess 7 , so that a detachment of the front end portions of the climbing or repelling aid 6 is held against the ski body hinan. The front-side undercuts or depressions 47, 48 in the skiseitigen recess 7 can be formed in a simple manner by opposite the base 11 of the recess 7 acute angled inwardly, frontal wall surfaces 42, 42 '. Such a coupling may be particularly useful when the support member 5 of the climbing or kicking 6 has an arcuate curvature or bias.

In particular, it is expedient, with respect to a longitudinal section through the ski body - according to Fig. 9 - Form a dovetail-like coupling between the distal ends of the support element 5 and the distal ends of the skiseitigen recess 7. This dovetail-like coupling, in conjunction with a support element 5 curved in the original state, makes possible Fig. 8 - A particularly practical handling in relation to connection operations between the climbing or kicking 6 and the ski body. In addition, especially the distal end portions of the climbing or kicking 6 are better secured against unwanted separation or deviation with respect to the tread 8 of the ski body. Adverse or undesirable braking effects during the sliding phase with the ski body can be kept behind. In the inserted into the recess 7 state of climbing or kicking 6, the support member 5 is transferred to an at least approximately planar orientation, as best of Fig. 9 is apparent. The corresponding Velcro surfaces 9, 10 or the alternative, mutual adhesive surfaces, or even magnetically active surfaces, as described below, thereby effecting a maintenance of the straightened shape of the support element 5, as this Fig. 9 can be seen.

By curved in the original state arcuate and thus slightly shortened in the longitudinal direction of the longitudinal extension of the support element 5 this can be easily inserted into the dovetail-shaped recess 7 in longitudinal section, as can be seen from a synopsis of Fig. 8, 9 is apparent. In order to achieve a permanent connection or to avoid an undesired detachment relative to the recess 7, the climbing or kicking aid 6 or its support element 5 is only to be pressed into the recess 7, so that in particular the longitudinal middle section of the climbing or kicking aid 6 is connected via the Velcro surfaces 9, 10 or via the corresponding adhesive surfaces with the base 11 of the recess 7. In adhesive- or adhesive-free design of the distal end portions of the support element 5 and / or the recess 7 - according to the representations in the Fig. 8, 9 - This final connection or pressing operation can be carried out relatively free of clamping or tension after 5 longitudinal compensation movements relative to the recess 7 can take place in the distal end portions of the support element.

Instead of the partial Velcro connection between the support element 5 and the recess 7, it is also possible to provide a partial adhesive or magnetic connection, which can be activated and deactivated several times. In the case of the formation of adhesive surfaces, the first adhesive surface by an in Fig. 8 indicated in dashed lines adhesive layer 49 is formed, which is arranged on the recess 7 facing the rear or flat side of the support element 5. This adhesive layer 49, which can be activated and deactivated several times, is formed by a permanently adhesive, non-hardening adhesive known per se in standard climbing skins. The further adhesive surface at the base of the ski-side recess may be formed by a corresponding adhesive layer or preferably by the plastic base 11 of the recess 7. In particular, the previously described Distance layer 39 with the adhesive layer 49 enter into an active as needed and deactivatable adhesive compound.

Instead of the previously described adhesive or Velcro surfaces 9, 10 between the support member 5 and the skiseitigen recess 7, according to a particularly advantageous, in itself independent embodiment, a magnetic effect between the climbing or repelling 6 and the recess 7 in the ski body for removable removable attachment the climbing or repelling aid 6 are used with respect to the ski body, as is the embodiment according to the 10, 11 can be seen schematically.

Also in this embodiment, the climbing or kicking 6 either a fur or brush-like, or - as shown schematically - a scaly profile-like Rückgleithemmer 4 include. The respective Rückgleithemmer 4 is in turn fixed permanently on a plate or trough-shaped support member 5, in particular permanently glued. The support element 5 in this case has a higher flexural rigidity or dimensional stability than a relatively formflexibler, fur or brush-like Rückgleithemmer.

The side or flat side of the support element 5 facing away from the backrest inhibitor 4 has at least one first magnetically active surface 50, 50 ', 50 ", which has at least one further magnetically active surface 51, 51', 51" at the base 11 of the recess 7 if necessary, in and out of magnetic interaction, in particular in and out of magnetic attraction can be displaced. This means that the support element 5 is held with the respective Rückgleithemmer 4 by the magnetic interaction between the support member 5 and the base within the recess 7 and secured against accidental falling out. The respective magnetic interaction, in particular the magnetic attraction between the magnetic or magnetically attracting surfaces 50, 50 ', 50 "and 51, 51', 51" is so high that an undesirable detachment of the climbing or repelling 6 relative to the Ski body can be almost excluded. Namely, the magnetic forces only have to withstand the forces occurring vertically to the base 11 of the recess 7. These are relatively small in comparison to the forces running parallel to the running surface 8, which would cause a relative displacement between the climbing or pushing aid 6 and the ski body. These largely parallel to the tread 8 extending relative forces, in particular the repulsive forces between the Skikörper and the snow background are thereby reliably and easily absorbed by the at least partial inclusion of the climbing or kicking 6 and the support element 5 within the skiseitigen recess 7. In particular, the corresponding magnetic forces or the previously described Velcro or adhesive forces are sufficient in order to withstand the interactions occurring between the climbing or kicking aid 6 and the ski body during normal use of the ski 1 such that undesired separations or disadvantageous gap formation are virtually eliminated can be.

It is also expedient if the support member 5 is slidably inserted into the recess 7 and equal movement of the recess 7 can be removed. This means that at least the longitudinal side walls of the support element 5 and the longitudinal side walls of the recess 7 have no form-locking connection and no reciprocal locking enter. If necessary, between simple facing surfaces or front ends of the support element 5 and the recess 7 a simple, easily surmountable positive connection can be performed, as shown in the Fig. 8, 9 was exemplified. In particular, it is expedient to design the support element 5 and the corresponding recess 7 in such a way that a maximum width 44 of the support element 5 within its various longitudinal sections corresponds to a clearance 52 of the recess 7 within their respective associated longitudinal sections, as can be seen Fig. 11 or also off Fig. 5 is removable. This ensures that the support member 5 is substantially gap-free and slidably inserted into the recess 7, without in the longitudinal side edges mutual form-fitting connections, which prohibit vertical relative to the tread 8 aligned relative displacements, must be activated and deactivated. As a result, a particularly rapid and effortless assembly and disassembly is achieved, wherein, depending on the respective magnetic, Velcro or adhesive forces optionally no auxiliary tools for dismantling the ski body are required.

The magnetically interacting, first and further surfaces 50, 50 ', 50 "and 51, 51', 51" can be replaced by at least one permanent magnet 53, 53 ', 53 "and by at least one ferromagnetic element which can be set into a magnetically attracting action Material 54, 54 ', 54 "be formed. How best of the 10, 11 can be seen, the first magnetically active surface 50, 50 ', 50 "of the support element 5 by at least one ferromagnetic element or material 54, 54', 54" facing away from the Rückleithithemmer 4 Side of the support element 5 may be formed. Alternatively, the support element 5 for the Rückgleithemmer 4 may be at least partially made of ferromagnetic material, for example of metal. In particular, the support element 5 may be formed by a strip-shaped sheet metal element, wherein the respective Rückgleithemmer 4 is glued or sprayed on at least one flat side of the sheet metal element.

The ferromagnetic portions of the support element 5 or the at least one ferromagnetic element or material 54, 54 ', 54 "can however also be formed by metallic blocks or plates on the rear side 55 of the support element 5. The respective ferromagnetic elements or materials 54, 54 ', 54 "and the alternatively provided permanent magnets preferably terminate flush with the back 55 of the support element 5 from. In particular, the respective ferromagnetic elements or materials 54, 54 ', 54 "are arranged in recesses 56, 56', 56" of the support element 5, as shown in FIG Fig. 11 was exemplified. The corresponding, ferromagnetic elements or materials 54, 54 ', 54 "can be pressed with the support element 5, injected, adhesively bonded thereto and / or snapped into the support element 5 in a form-fitting manner in order to achieve a tear-off or detachment-proof connection.

The further, in particular the ski-side arranged, magnetically active surface 51, 51 ', 51 "is preferably formed by at least one permanent magnet 53, 53', 53", which is fastened to the base 11 of the recess 7.

Optionally, the base 11 of the recess 7 or at least the visible surface of the permanent magnets 53, 53 ', 53 "may be coated with a varnish or cover layer in order to prevent wetting of the permanent magnets 53, 53 ', 53" with water and thus to minimize or avoid the formation of rust ferromagnetic elements or materials 54, 54 ', 54 "may be provided on the support element 5.

Preferably, at least in the distal end portions, that is in the region of the front ends of the support element 5 and the recess 7 mutually corresponding, that is displaceable in magnetic attraction magnetic surfaces 50, 51 and 50 ", 51" is formed. Preferably, three magnetically engagable pairs of magnetic surfaces 50, 50 ', 50 "and 51, 51', 51" are provided, wherein in the central portion and in the distal end portions each having a magnetically active element pair is formed, as in the 10, 11 is apparent.

The recesses 57, 57 ', 57 "for receiving the permanent magnets 53, 53', 53" are preferably formed in the spacer layer 39 formed of plastic of the ski body. As a result, it is possible to achieve a reliable or tear-resistant fixing or pressing in of the preferably cylindrical or tablet-shaped permanent magnets 53, 53 ', 53 ", etc. Such permanent magnets have high magnetic attraction forces and these embodiments of permanent magnets are comparatively inexpensive and robust with respect to the mounting or permanent magnet. installation process.

Instead of forming at least one permanent magnet 53, 53 ', 53 "in conjunction with at least one magnetically attractable, ferromagnetic material 54, 54', 54", it is also possible to provide pairs of magnetically attracting permanent magnets, or alternatively the at least one permanent magnet 53, 53 ', 53 "to the support element 5 and the at least one ferromagnetic element 54a to be assigned to the ski body, as shown in FIGS Fig. 12, 13 is apparent. In particular, in the base plate 23 of the support element 5 at least one recess 58, 58 ', 58 "be executed, in which at least one permanent magnet 53, 53', 53" is pressed or embedded. This at least one permanent magnet 53, 53 ', 53 "can enter into magnetically attracting interaction with at least one ski-side permanent magnet 53a or alternatively with at least one ferromagnetic element or material 54a arranged on the side, and thus the support element 5 or the corresponding climbing or kicking aid support within the skiseitigen recess.

How best Fig. 13 can be seen, the support member 5 in its in the usual direction of travel - arrow 12 - related, front end wedge or wedge-shaped be designed to form spoiler or Abweiserflächen, which can contribute to the lowest possible sliding resistance of the ski body relative to the ground.

It is expedient if the at least one permanent magnet 53, 53 ', 53 "is sandwiched between the base plate 23 of the support element 5 and a backrest inhibitor 4 connected to the support element 5, as shown in FIG Fig. 12 has been illustrated schematically. As a result, the risk of damage or rusting on the permanent magnet 53, 53 ', 53 "is held back.
