Description

The invention relates to a ski, in particular a touring or cross-country skis, with a rückwärtsithemmenden climbing or repelling aid, which is attachable to the underside of the ski at least in the longitudinal central portion and, if necessary, removable from it.

A generic ski in conjunction with a at the bottom of the ski as needed attachable and detachable from the ski climbing or kicking is in the WO 2007/004034 A1 , of the DE 20 2005 010 571 U1 and in the DE 20 2005 013 673 U1 disclosed. The climbing or kicking aid comprises a fur strip which can be stuck on in the middle ski area. At skispitzenseitigen end of the fur strip a the end of the fur strip overlapping and superior plate is provided, which is firmly connected to the fur side of the fur strip with the fur strip. A free end of the plate protrudes beyond the ski tip side end of the fur strip to form a convexly curved transition between the tread plane of the ski and the reverting-inhibiting fur side of the fur strip. The side facing away from the fur side back of the fur strip is designed as a full-surface adhesive surface over which the fur strip is directly aufklebbar on the tread of the ski. A disadvantage is that this sticking requires the user a certain level of skill, and that inappropriate or incorrect or untidy attachment of the fur strip, the resulting performance of the ski turns out negative.

In addition, embodiments are known in which the climbing aid, in particular the climbing skin, is applied or glued on a shape-stabilizing support element. This carrier element can then be used subsequently in a corresponding recess in the bottom of the ski and, if necessary, removed from the recess again. Such support structures or support elements for the rebacking-inhibiting fur strips are in the FR 2 792 213 A1 , of the US 5,292,147 A , of the US 2003/0090086 A1 , of the AT 345 703 B , of the AT 351 415 B , of the CH 244 368 A , of the DE 27 52 397 A1 and in the AT 508 684 A1 , which is due to the applicant disclosed. The disadvantage here is that these support elements for the anti-rebar element, in particular for the inherently flexible fur strips, increase the weight and structural complexity of the ski. This weight gain is disadvantageous in terms of achievable, athletic performance of the user. Moreover, in these previously known embodiments, the handling of the climbing aid, in particular with respect to its mounting on skis, for sporting goods retailers and end users, especially for the sports practitioners, only partially satisfactory.

The present invention has for its object to provide a ski, especially a touring or cross-country ski, in which the climbing or kicking aid can be installed quickly and easily, especially without the aid of tools, and as accurately as possible on the underside of the ski.

This object of the invention is achieved by a ski according to the features in claim 1.

An advantage achieved by the measures according to claim 1 lies in the fact that handling is considerably simplified with regard to the attachment of this climbing or kicking aid to the underside of the ski. In particular, this can be achieved within a relatively short time, a very precise or scheduled attachment of the climbing or kicking aid, which includes the form slack fur strip. The finding and taking of the optimized or manufacturer provided relative position relative to the ski is relatively simple and fail-safe feasible. In particular, it is ensured via the at least one recess or depression in the underside of the ski that the relative position of the climbing or kicking aid with respect to the ski longitudinal direction corresponds to an optimum determined by the ski manufacturer. In addition, in a simple manner, the alignment of the relatively flexible or pliable fur strip is facilitated with respect to the ski longitudinal axis. In particular, it can be ensured by the measures according to the invention in a relatively simple, reliable and fail-safe manner that the longitudinal axis of the climbing or repelling aid is aligned as parallel as possible to the ski longitudinal axis, without requiring the user or user increased dexterity. In particular, adhering by adhesion forces or by an adhesive layer, in flexible and flexible soft fur strips of climbing or kicking can relatively accurately or by the measures according to the invention in a relatively short time and without the need for particular skill or without the need for special training effort Functionally optimized to be attached to the ski base. This both in relation to the relative position to Ski, as well as in relation to the orientation of the self-conforming or flexible, self-adhesive fur strip.

In addition, it is ensured by the measures according to the invention that the suitably mounted climbing or pushing aid ensures optimized performance and high separation safety. A major advantage lies in the fact that despite these handling simplifications for the user or sports practitioners, the structural complexity of the system is minimized and it is thus a producer of skis invention or climbing or repelling aids allows to keep the production costs relatively low , Consequently, it is possible to make the corresponding sport exercise available to a larger group of people.

The measures according to claim 2 or 3, a structurally simple as possible and thus production technology relatively low-cost design is created to achieve an optimized and as accurate as possible or proper orientation of the self-adhesive fur strip relative to the tread of the ski. The finding and taking the proper or planned relative position and alignment between the ski and the climbing or kicking aid is relatively quickly and easily implemented.

Also advantageous are the measures according to claim 4, as a high-strength or durable connection between the flexible skin strips and the positioning can be constructed. In particular, an unwanted detachment of the fur strip from the positioning aid can thereby be kept back even with coarse handling or careless handling. In addition, the corresponding connection method is possible to implement as economically as possible, so that the production costs of the appropriately equipped ski can be kept as low as possible.

Also advantageous are the measures according to claim 5, since on the one hand an optimized performance in relation to the sliding and repelling behavior of the ski can be achieved. In particular, impact edges or friction-increasing shear edges between the snow background and the boundary edges of the climbing or kicking aid are thereby reduced or completely avoided. In addition, this minimizes the likelihood of undesired detachment of the glued-on fur strip. In particular, thereby becomes a so-called Tufts of snow or a gradual accumulation of snow and a concomitant braking effect and / or a gradual Ablösendendenz in the transition region between the tread of the ski and the climbing or repelling aid held back.

By the measures according to claim 6 it is ensured that the ski or its tread or Untergurtkonstruktion is only marginally weakened in the section with the formflexible fur strip, in particular only minimally deepens or must be milled. In particular, a relatively small depth of the recess over wide surface portions of the recess in the underside of the ski is therefore sufficient, after the depth of the recess only has to correspond approximately to the thickness of the form-flexible, relatively thin skin strip. At the same time it is ensured by the measures according to claim 6, that the positioning aid is sunk sufficiently deep in the region of the second recess to ensure the most continuous possible transition between the successive longitudinal sections of the climbing or kicking. In addition, it is ensured that the front boundary edge of the positioning aid can not cause snow accumulation, so that during the forward-sliding phase of the ski as possible, no braking effect is caused.

Another advantage are the measures according to claim 7, as a structurally particularly simple and relatively lightweight positioning is created. In addition, the requirements with regard to the most exact positioning and alignment of the fur strip with respect to the ski longitudinal direction or ski longitudinal axis in conjunction with a correspondingly shaped recess in the tread of the ski can thereby be optimally accomplished.

Also of advantage are the measures according to claim 8, since the simplest possible handling of the climbing or kicking aid is favored. In particular, a relatively effortless positioning of the positioning aid with respect to the predefined recess on the underside of the ski is made possible. In addition, this also ensures that the self-adhesive fur strip occupies the proper relative position and orientation with respect to the ski as soon as it is designed based on a planned positioning aid on the ski, in particular pressed against the underside of the ski or against the base of the recess and is glued accordingly.

A further advantageous measure is specified in claim 9. As a result, a rough advance positioning of the positioning aid can be made by the user or installer of the climbing or kicking aid and are corrections to achieve the desired or plan position relatively easily feasible. In particular, position corrections can be made thereby, without a repeated detachment and replacement of the positioning aid must be made. In addition, a sufficiently high holding force can be achieved in order to prevent unwanted detachment of the adhesive-free, magnetically kraftalterten portion of the climbing or repelling aid.

But also by the measures according to claim 10 it is ensured that the positioning aid is maintained after reaching the target or target position within the recess and is secured against unwanted detachment from the ski underside.

But even by the measures according to claim 11, an unwanted detachment of the positioning of the ski underside is held back. In particular, by means of these positive coupling means, an optimized relative positioning of the entire climbing or pushing aid can be ensured and it can also be ensured that the correct or planned position of the positioning means is reliably maintained even during use of the ski.

In the measures according to claim 12, it is advantageous that the climbing or kicking aid also builds up as little friction or resistance as possible when the climbing or kicking aid touches the ground during a forward sliding phase. In addition, the likelihood of separation tendencies due to snow accumulation or snow accumulation is reduced.

The measures according to claim 13 are also advantageous, since at least the positioning aid is at least partially recessed in a depression of the underside of the ski, while the adjoining longitudinal section, in particular the fur strip, can be glued directly to the underside of the tread covering. In particular, the back-inhibiting fur strip is not completely sunk in a recess on the underside of the ski, but at least a portion of the fur strip is glued directly to the underside of the tread covering. In addition to a particularly separation-proof connection of Climbing or repelling help with the ski can thereby be achieved as cost-effective production. In addition, this avoids a ski-side impact or impact edge on the climbing or kicking aid, which reduces the risk of separation and also minimizes the likelihood of undesirable braking effects.

Of particular advantage are the measures according to claim 14, as a complete integration of the positioning within the recess in the ski is made possible and thereby a planar or infinitely variable sliding surface or ski underside can be achieved.

Also advantageous are the measures according to claim 15, since a maximum surface can be built up to build up a return-inhibiting effect. In addition, this can be avoided by transverse edges or surface jumps or gradations in the tread or on the underside of the ski. The measures according to claim 15 thus favor the achievable performance in terms of sliding and repelling behavior of the ski.

According to the invention, in particular, a climbing or kicking aid is provided, which is recessed at least in sections in a depression or recess on the underside of the ski with respect to the longitudinal extent, wherein at least the ski-side, front boundary edge of the climbing or pushing aid is recessed in relation to the running surface plane. is sunk, wherein the front boundary edge of the skin or the front portion of the climbing or repelling aid is secured by magnetic force, by mechanical positive engagement, or by clamping force or by a press fit against unwanted detachment or lifting from the ski bottom, while the majority of Longitudinal extent of the climbing or kicking aid is formed by a flexible, flexible skin strip, which can be bonded by an adhesion surface or an adhesive layer with the ski underside. The corresponding climbing or kicking can be removed by the user if necessary and replaced by a different or by a new climbing or kicking aid. This replacement process can be made at any time at the user's request and this exchange or assembly process preferably without tools, especially without the aid of special tools feasible. Above all, an assembly process of the specified climbing or kicking aid on the underside of the ski is greatly facilitated by the measures according to the invention. In addition, the appropriate attachment particularly quickly and effortlessly carried out, this attachment can also be done very precisely or according to the manufacturer's optimum. In particular, the assumption of the planned relative position and the proper alignment of the climbing or repelling aid with respect to the underside of the ski can be achieved much more reliably.

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 are to be transferred to the new situation mutatis mutandis when a change in position. Furthermore, individual features or combinations of features from the different exemplary embodiments shown and described can also represent independent, inventive or inventive solutions.

All statements on ranges of values in the description of the present invention should be understood to include any and all sub-ranges thereof, e.g. the indication 1 to 10 should be understood to include all sub-ranges, starting from the lower limit 1 and the upper limit 10, i. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

In the Fig. 1 to 5 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 can be designed, on the one hand, as a cross-country ski for well-groomed or unpaved terrain, but also as a ski 1 for the practice of mountaineering sport.

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 means of this preloading height 2, the middle longitudinal section of the lower side or the running surface of the ski body is distanced in the unloaded state or under load conditions below a predetermined threshold value with respect to a planar surface. 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 regard to the ski longitudinal direction, in a cross-country ski, which is the preferred type of ski, there is at least one means for back-hemming, at least in the longitudinal center section 3 of the ski body. a climbing or repelling aid 4 is formed. In particular, at least in the region of a binding mounting zone or shoe boot section on the underside of the ski basic body a Rückrückithemmender longitudinal center section 3 is provided, which is formed by at least one climbing or kicking 4 or at least one climbing or kicking 4 includes. This rebound inhibiting section usually extends over approximately one third of the length of the ski. Optionally, this section can also be made shorter or extend in about more than two thirds of the ski length.

In the generic skis 1, the climbing or kicking 4 extends in about about 20-70% of the ski length, the skispitzenseitige end of the climbing or kicking 4 is positioned in a ski longitudinal section, which between a front and rear contact zone of the unloaded ski. 1 lies opposite a level surface. The skispitzenseitige end of the climbing or kicking aid 4 is thus outside the front blade portion of the ski 1 and thus comes with a corresponding pressure load against the top of the ski 1 with the ground, in particular with the snow ground in contact. Accordingly, the Rückgleithemmende longitudinal central portion 3 is carried out in relation to the total length of the ski 1 partially.

The climbing or kicking aid 4 is, if necessary, releasably secured to the underside of the ski body. According to the illustrated embodiment, the climbing or kicking aid 4 is made fur or brush-like. In particular, the effective surface of the climbing or kicking 4 comprises a so-called climbing skin 5, 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 against the ground and in a second, opposite direction as high as possible braking - Offers or Verkrallungswirkung against the ground, so that the Rückgleithemmende section serves as a slip-back protection or the climbing or kicking 4 defines.

The climbing or kicking aid 4 thus comprises a fur-like element, in particular a so-called climbing skin 5 with a multiplicity of hairs or fibers. In order to increase its unidirectional braking or inhibiting effect, these hairs or fibers may be arranged systematically, and they may also be slightly inclined relative to the ground or made angular.

This climbing skin 5 is relatively limp in itself or little dimensionally stable. In fact, the back-hemming fibers or fibers are typically arranged on a textile or fabric-like carrier layer 6. In addition, the climbing skin 5 has an elongated, strip-like shape and a small thickness. The per se formschlaffe, Rückgleithemmende fur strip or the climbing skin 5 of the climbing or kicking 4 is so flexible that this fur strip or the climbing skin 5 collapses or collapses without additional support effect under the influence of its own weight and changes its shape. In particular, the return-hemming fur strip of the climbing or kicking aid 4 has a dimensional stability or flexibility similar to a leather strip with the same dimensions.

In the state connected to the ski 1, the climbing or kicking aid 4 is at least partially accommodated or at least partly inserted therein in an elongated recess 7 running in the longitudinal direction of the ski in the underside or running surface 8 of the ski 1. By a frictional connection between the skin strip and the ski 1, in particular by an adhesive bond with the base in the recess 7 of the ski 1, the fur strip or the climbing skin 5 of the climbing or kicking aid 4 is finally sufficiently dimensionally stable to then to be able to transfer repulsive forces or anti-backlash forces between the ski 1 and the snow ground.

It is expedient here if the climbing or kicking aid 4 can be inserted into the recess 7 essentially without play in relation to the ski longitudinal and transverse direction. This means that the climbing skin 5 is positioned and received without play, or at least approximately free of play, transversely to the longitudinal direction of the ski and in the longitudinal direction of the ski by boundary surfaces or boundary walls 9 of the recess 7. In order to avoid that the climbing or kicking aid 4, that is, the climbing skin 5 accidentally falls from the recess 7 or gradually dissolves from the recess 7, the rear side facing away from the fur side of the climbing skin 5 with an adhesive or adhesive layer 10th provided, which is required with an adhesive surface 11 at the bottom of the recess 7 in and out of contact can be brought. A holding force of this adhesive connection is dimensioned such that the user can make a preferably tool-less assembly and disassembly of the climbing or kicking 4 relative to the ski body. In addition, it is expedient if the repeatedly repeatable sticking and detachment of the climbing skin 5 or of the fur strip can take place under normal ambient temperatures, that is to say no elevated temperature or no additional heat is required.

The climbing or kicking aid 4 is thus sufficiently tear-off or detachment within the recess 7 on the underside of the ski body or in by the action of an adhesive view 10 in combination with a corresponding adhesive surface 11 with respect to the forces occurring during use of the ski 1 held the tread 8 of the ski body.

The holding force or connection reliability of the climbing or kicking aid 4 within the recess 7 is achieved at least partially by the bonding forces between the adhesion or adhesive layer 10 and the associated adhesive surfaces 11. According to an advantageous development, the resulting holding force between the climbing or kicking 4 and the ski-side recess 7 can be at least partially increased by clamping or supporting forces between outer or peripheral surfaces of the climbing skin 5 and associated boundary surfaces or boundary walls 9 of the recess 7 , But it can also be a completely play-free nesting between the climbing skin 5 and the recess 7 completely sufficient to increase the holding force or the separation security of the climbing or kicking 4.

The predominant part of the anti-rebar effect of the climbing or kicking aid 4 is achieved by the undirectional braking effect or by the clawing effect of the climbing skin 5 relative to the respective ground, in particular with respect to snow or ice. Especially when the Rückgebeiemmende longitudinal central portion 3 of the ski 1 as fully as possible contact with the ground in contact, a high degree of repelling force against the ground can be achieved to support the most impulsive or efficient repulsive movement in the direction of the usual direction of travel.

The climbing or kicking aid 4 thus comprises a climbing skin 5 or a fur strip 12 with natural or artificial hairs, the structure of which is also known from touring skis. The fur strip 12 per se is relatively loose in form or bend soft. In particular, this fur strip 12 of the climbing or kicking aid 4 is so flexible in shape that it can be collapsed or rolled up non-destructively. This is accomplished essentially by the textile or fabric-like carrier layer 6 of the fur strip 12. By means of the adhesive layer 10 on the side facing away from the fur side back of the carrier layer 6 of the fur strip 12 is provided for multiple, if necessary releasable sticking to the underside of the ski 1 or for gluing into the recess 7 on the lower ski side.

The climbing or kicking aid 4 designed according to the invention has an end section 18 on at least one longitudinal end, preferably at least on the ski-tip-side longitudinal end 13, which has a higher dimensional stability or higher dimensional stability in comparison to the other sections of the fur strip 12.

In the execution according to Fig. 3 Thus, more than 100% of the length of the climbing or kicking aid 4 is the return-inhibiting effect of the fur strip 12 over the entire length of the as needed removable or exchangeable climbing or kicking aid. The fur strip 12 is formed relatively slack over most of its longitudinal extent and has only a relatively small proportion of its longitudinal extent, in particular less than 10% of the length of the fur strip 12, a comparatively higher stiffness. But it is also possible that only the outermost edge or edge portions at the front or skispitzenseitigen longitudinal end 13, in particular stiffened in the ski-side end portion 18 are executed or hardened. In particular, can be provided that primarily the front end edge 14 of the climbing or repelling aid 4 in comparison to the other boundary edges of the climbing or repelling aid 4 is designed to be relatively dimensionally stable or rigid.

It is essential that a positioning aid 15 is formed by this partial stiffening in at least one end portion 18 of the climbing or kicking aid 4, preferably at skispitzenseitigen longitudinal end 13 of the fur strip 12, which is the assignment or attachment of the climbing or repelling aid 4 at the bottom of the ski 1, in particular with respect to the recess 7 facilitates. In particular, this positioning aid 15 of the climbing or kicking aid 4 is designed for cooperation with the correspondingly shaped recess 7 or a correspondingly contoured depression in the underside or running surface 8 of the ski 1. The positioning aid 15 is thus provided for facilitating finding or taking a planned desired or relative position and orientation of the flexible skin strip 12 relative to the ski 1.

According to the embodiment in Fig. 3 the positioning aid 15 comprises at least one positioning edge 16, which is designed to cooperate with at least one stop edge 17 of the recess 7. However, according to an expedient measure, at least two angularly extending positioning edges 16 are formed on the climbing or kicking aid 4, as shown in FIG Fig. 3 was exemplified. As a result, the relative position and orientation of the climbing or repelling aid 4 or of the skin strip 12 can be clearly predefined in relation to the ski 1 by the ski producer.

According to an expedient measure, it is provided that the climbing or kicking aid 4 is designed to be free of adhesive in the region of the positioning aid 15. That is, the adhesive layer 10 of the fur strip 12 extends only over a portion of the total length of the climbing or pushing aid 4, as in the embodiments according to the Fig. 6-13 was illustrated. In particular, the skip side, front end portion 18, in which the positioning aid 15 is formed, has no adhesion or adhesive effect against the ski 1 and against the recess 7. As a result, a relatively effortless and accurate positioning of the climbing or repelling aid 4 is possible. The adjoining the positioning aid 15 longitudinal portion of the fur strip 12 is preferred consistently provided with an adhesive layer 10 or other, adhesive-acting means, so that a sufficiently large adhesive surface 11 with respect to the ski base or with respect to the base surface of the recess 7.

In the Fig. 6 to 13 Various embodiments of the climbing or kicking aid 4 in combination with a correspondingly formed ski 1 are illustrated schematically.

According to the embodiment according to Fig. 6 is arranged at the skispitzenseitigen end of the fur strip 12 positioning aid 15 formed of plastic. In particular, this positioning aid 15 is molded onto the skip-side end section 18 of the fur strip 12. Expediently, the positioning aid 15 is sprayed onto the rear side of the fabric-like carrier layer 6 of the hide strip 12 facing away from the hide side by means of a plastic injection molding process. A longitudinal extent of the positioning aid 15 can be between 1 cm and 8 cm, in particular be approximately 3 to 5 cm. The positioning aid 15 sprayed onto the carrier layer 6 thereby enters into a high-strength or particularly tear-resistant connection with the fur strip 12, in particular with its fabric or textile-like carrier layer 6. Instead of a Anspritzvorganges with respect to the ski 1 facing flat side of the fur strip 12, it is also possible to overmold the skispitzenseitigen end portion 18 of the fur strip 12, as in Fig. 7 was presented. As a result, the separation security between the fur strip 12 and the end face molded thereon positioning aid 15 can be further increased.

In the embodiment according to the Fig. 6, 7 is the positioning aid 15 within the recess 7 by form-fitting coupling means 19, 20 releasably supported as required and at the same time against the ski 1 plan or properly positioned. In the execution according to Fig. 6 the first coupling means 19 is formed by a latching pin 21, which according to Fig. 7 with a corresponding mold cavity 22, or according to Fig. 6 is displaceable with a corresponding second coupling means 20 in the form of a latching pan 23 in and out of positive engagement. Such a detent pan 23 - Fig. 6 - offers compared to a simple mold cavity 22 with undercut - Fig. 7 - The advantage that the ski core 24, which is usually formed of foam plastic, is protected from the ingress of moisture and thereby the risk of undesirable Delamination is avoided in ski construction. This is particularly useful when the ski core 24 is formed of foamed polyurethane.

The recess 7 in the tread 8 of the ski 1 is adjusted with respect to their length and width dimension to the length and width and to the contour of the climbing or kicking 4, as shown in the Fig. 2, 3rd was illustrated. Alternatively, it is also possible that only a portion of the base of the climbing or repelling aid 4 is recessed or recessed within the recess 7, as shown in the Fig. 9, 10th has been illustrated schematically. In particular, at least the front ski-side end section 18, including the positioning aid 15, is accommodated and positioned within the recess 7. Another embodiment with partial depression or sinking of the climbing or kicking aid 4 in the tread surface or below the tread plane is in Fig. 11 illustrated.

The positive coupling means 19, 20 between the positioning aid 15 and the recess 7 in the lower ski side can also be formed by a simple mechanical connector 25, as shown in FIG Fig. 12 is shown. Here, a plug-in pin 26 is provided on the positioning aid 15 and a receiving bore 27 corresponding thereto is provided on the underside of the ski or in the recess 7. Alternatively to a simple plug connection 25 - according to Fig. 12 But it is also possible to provide a snap or latching connection 28, as in Fig. 11 is exemplified. In particular, it is expedient if the positioning aid 15 at the ski-tip end of the climbing or kicking aid 4 has at least one resiliently restoring detent projection 29 which can be brought into and out of positive engagement with at least one corresponding detent groove 30. This plug-in or latching connection 25, 28 is designed such that expediently no tools or tools are needed to build the positive connection and can cancel if necessary. It is essential that the ski-tip-side end portion 18 of the fur strip 12 via the positioning aid 15 relative to the ski 1 releasably supported and at the same time is positioned according to plan, without ambiguity in relation to the scheduled relative position and orientation of the fur strip 12 may arise.

According to the embodiment according to Fig. 13 the positioning aid 15 can be formed by a positive-acting lift-off securing device 31 for the front end section 18 of the climbing or kicking aid 4. In this case, a skip side boundary surface 32 of the recess 7 forms an undercut 33, which in combination with a corresponding, preferably inclined boundary surface 34 of the positioning aid 15 forms the positive Abhebesicherung 31 for the positioning aid 15. Such a lift-off 31 is structurally relatively simple, relatively inexpensive to produce and thus particularly economical. In addition, a simple relative positioning of the climbing or kicking aid 4 is made possible relative to the ski 1 and is subsequently ensured by the adhesive bond of the fur strip 12 relative to the ski 1, the relative position of the positioning aid 15 with respect to the ski 1. In particular, slippage of the preferably adhesive-free positioning aid 15 is prevented after sticking of the fur strip 12 to the ski 1 - as well as a lifting or detachment of the positioning aid 15 in the vertical direction to the tread plane.

In the embodiment according to Fig. 13 the positioning aid 15 is formed by a permanently connected to the fur strip 12 plate 35, which consists in particular of thermoplastic material. This plastic plate 35 is arranged in at least one end portion 18 of the fur strip 12. According to the illustrated embodiment in FIG Fig. 13 In this case, an overlap 36 is formed between the fur strip 12 and the plastic plate 35, through which an approximately constant thickness of the climbing or repelling aid 4 is achieved with respect to a longitudinal section view. At the same time, a high-strength or permanently reliable connection between the corresponding positioning aid 15 and the fur strip 12 can thereby be established.

According to an expedient embodiment, as described in the Fig. 6, 7 has been exemplified, the recess 7 for receiving the climbing or kicking 4 different depths 37, 38 have. In this case, a first portion 39 is provided with a first depth 37 for receiving the self-adhesive fur strip 12. In addition, a further portion 40 immediately adjacent to the first portion 39 is provided within the recess 7, which portion 40 has a comparatively greater depth 38 and is designed to receive or embedding the positioning aid 15. In particular, the depth 38 of the recess 7 in the cover portion 40 with the positioning aid 15 so dimensioned that caused by the positioning aid 15 increase in thickness of the fur strip 12 is compensated such that the rückbelithemmende fur side of the fur strip 12 extends as flat as possible at the inserted into the recess 7 state of climbing or repelling aid. These measures are particularly based on Fig. 6, 7 clearly visible.

According to appropriate embodiments, as shown in the Fig. 8 9, 10, the climbing or kicking aid 4 in the section with the positioning aid 15 can comprise at least one magnetically active surface 41, which can be displaced into and out of magnetic attraction with at least one further magnetically active surface 42 at the bottom of the recess 7 , The respective magnetically active surfaces 41, 42 may be formed by at least two magnetic attraction displaceable permanent magnets 43 or by a combination of a permanent magnet 43 with a metal element 44, as is apparent from Fig. 10 is apparent. Preferably, the permanent magnet 43 is positioned on the ski side and the metal element 44 associated with the climbing or kicking aid 4, in particular integrated in this. Of course, it is also an inverse embodiment, as in Fig. 10 is shown possible. It is essential that the magnetically active metal element 44 or the permanent magnet 43 is connected tear-proof with the climbing or kicking aid 4. For this purpose, the corresponding element may be cast or glued into the plastic plate 35, as shown in FIG Fig. 8 is illustrated. According to an expedient measure, it is also provided that a front edge 45 of the positioning aid 15 that is at the front in relation to the planned direction of travel of the ski 1 is at least partially positioned or recessed within the recess 7, as for example Fig. 6, 7 , and 11-13 can be seen. As a result, a front braking or Aufstaukante for snow is avoided. In addition, the likelihood of unwanted detachment of the fur strip 12 or the positioning aid 15 is thereby arrested.

Instead of a complete recording of the fur strip 12 within the recess 7 and a partial placement of the front end portion 18 is possible, as shown in the Fig. 9, 10th and 11 was presented. In particular, it may be provided that the front end section 18 of the climbing or kicking aid 4 or of the fur strip 12, in particular the section with the positioning aid 15, which is frontally inclined with respect to the planned direction of movement, is at least partially received by the recess 7, whereas the adjoining portion of the climbing or kicking aid 4 and the fur strip 12 is the adhesive patch surfaces of the ski 1 repeatedly and, if necessary, it is removable.

According to an expedient embodiment in the rear end portion of the recess 7 and a transition ramp 46 between the bottom of the recess 7 and the tread surface or the tread 8 may be formed, as best of the Fig. 9, 10th and 11 is apparent.

According to an advantageous embodiment, the front or skispitzenseitige end portion of the climbing or kicking aid 4 is executed either rounded - Fig. 9 - or tapering trained or wedge-shaped tapering executed, as exemplified in Fig. 3 is shown. As a result, the foremost end edge 14 of the climbing or kicking aid 4 is made as narrow as possible or snow-repellent, so that the formation of a braking edge is obstructed. According to an expedient embodiment, as it Fig. 2 it can be seen, the relative to the direction of travel of the ski 1, the rear end portion of the recess 7 may have a gradually decreasing depth 37 '. This depth 37 'is dimensioned smaller than the general depth 37 of the recess 7. This prevents a rear braking edge in the rear end portion of the recess 7 avoided. In particular, this can be created in a simple manner tolerance compensation, which keeps losses of performance in the case of a tolerance slightly thinner skin strip 12 hinan.

From the illustrated embodiments according to the 6 to 12 It can be seen that the positioning aid 15 is always arranged on the opposite side of the fur side of the fur strip 12, in particular the adhesion or adhesive side of the climbing or kicking aid 4 is assigned next.

In addition, it can be seen in all embodiments that the positioning aid 15 on its side facing away from the ski 1 flat side over the entire surface clad with the fur strip 12, in particular completely covered by the fur strip 12. This maximizes the area of reverse-inhibiting climbing skin 5 on the climbing or kicking aid.

According to the illustrated embodiments, the front portion of the rising or pushing aid 4, in which the positioning aid 15 is formed, within the recess 7 by positive engagement, by magnetic force, or alternatively by a mutual clamping or pressing force, in particular be supported by a press fit , An attachment or tightening of the front end portion 18 of the climbing or kicking 4 is thus not required. In particular, a holding force between the positioning aid 15 and the ski 1 in a mounted climbing or pushing aid 4 is constructed directly between the underside of the ski 1 and the facing, nearest flat side of the positioning aid 15, as the Fig. 6 to 13 can be seen.

The embodiments show possible embodiments of the ski 1 and the climbing or kicking aid 4, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather also various combinations of the individual embodiments are possible with each other and this Variability due to the teaching of technical action by objective invention in the skill of those working in this technical field is the expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.

For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the ski 1 or of the climbing or kicking aid, these or their components have been shown partly unevenly and / or enlarged and / or reduced in size.
