Description

The invention relates to a climbing aid for releasably releasable attachment to the underside of a ski as well as a combination of a climbing aid in conjunction with a ski, as indicated in the introductory part of claims 1, 2.

Climbing aids, which are fastened on the underside of skis, if necessary releasably to be able to cope with terrain as quickly as possible or effortlessly, are known from the prior art in various designs. Such climbing aids usually include a fur-like Rückgleithemmer, whereby these climbing aids are colloquially referred to as "climbing skin". Such climbing skins are usually provided on their active or active surface over the entire surface with a plurality of fine hairs, said hairs are aligned or attached to the substrate so that in a sliding movement along a first direction or in the direction of the desired locomotion as possible low sliding resistance against the substrate is present and in a relative movement of the climbing aid in the opposite direction as high as possible sliding resistance is present or a repelling effect against the ground can be achieved. In addition to the known climbing skins, there are also climbing aids using sawtooth-like shed profiles, with which as unidirectionally high as possible sliding or in the opposite direction the highest possible repulsion effect or the best possible Rückgleithemmung can be achieved.

It is also known to provide only portions of the need-releasably attachable Steighilfemittels with Rückgleithemmenden means and form the remaining portions of this Steighilfemittels with relatively higher lubricity, as for example in the DE 93 04 437 U1 or the CH 700 590 B1 was proposed. This is intended to achieve a compromise between the best possible climbing ability and the best possible slipperiness.

Furthermore, it is known to provide a split in the longitudinal direction climbing skin comprising two Steigfellstreifen which Steigfellstreifen respectively the longitudinal side edges of a Schis be assigned. The individual climbing skin strips are directionally flexible in order to allow an alignment with the sidecut or side contour of the ski, as described in US Pat EP 1 925 345 A1 is specified. However, handling such a construction is relatively time consuming and requires an increased level of skill. Furthermore, the mechanical robustness of such an embodiment is only partially satisfactory.

In contrast to, if necessary, releasably attachable Steighilfemitteln, it is also known to provide in the outsole of skis milled or recessed extending in the longitudinal direction Schilängsrichtung grooves, in which grooves then strips of Rückgleithemmenden means used and permanently attached. Such longitudinal grooves in the outsole require complex, mechanical processing or milling operations in the course of the production of the ski body. In addition, these schiseitig formed longitudinal grooves cause at least at their end-side end portions sharp-edged transitions, which adversely affect the sliding behavior of the ski body. In addition, by the recessed in the longitudinal grooves arranged, back-inhibiting climbing aids their effectiveness against the ground affected. Such permanently secured in grooves or in other recesses in the outsole or exchangeable by mechanical coupling devices fastened, re-hindering means are for example in the FR 2 652 271 A1 . CH 219 054 A . AT 350 945 B . FR 2 301 274 A1 . DE 1 149 653 A . CH 570 178 A5 or the AT 329 417 B disclosed. In addition to a complex or costly production process for the creation of such Schier with integrally arranged Steighilfemaßnahmen for the suppression of unwanted sliding back such Schier are in terms of sliding in the course of departures unsatisfactory.

The present invention has for its object to provide a Rückgleithemmende climbing aid for skis, which provides a good Rückgleithemmung, in the course of downhills has the highest possible lubricity, a possible power saving climb in the course of overcoming gradients and possible cost feasible. In addition, the combination of ski and Rückgleithemmendem climbing aid or their technical interaction to improve.

This object of the invention is achieved on the one hand by the subject matter of claim 1 and independently by the subject matter of claim 2. Advantageous embodiments of the invention are the subject of the dependent claims.

According to the invention a climbing aid is formed, which is provided for releasably attaching to the underside of a ski as required. This climbing aid comprises a pliable, strip-shaped support layer, having a first longitudinal end for connection to the front tip section of a ski and a distal distal further longitudinal end, wherein the length of the support layer substantially corresponds to the length of the ski to be assigned. The climbing aid has an adhesive side, which is provided for adhesive assignment to the underside or to the outsole of a ski. At the opposite side of the adhesive side flat at least one Rückgleithemmender Steighilfeabschnitt and at least one a comparatively higher lubricity exhibiting sliding portion is formed. The sliding portion extends from the first longitudinal end, at least over a longitudinal section between 20% and 50% of the length of the base layer and at the same time over the entire width of the base layer. With regard to the longitudinal direction of the support layer, at least one riser section at least partially covering the support layer in the width direction is formed following this sliding section, which extends without interruption with respect to the longitudinal direction of the support layer to the further longitudinal end of the support layer.

According to a further embodiment of the invention, a ski is provided in combination with a climbing aid, which climbing aid is provided for releasably attaching to the underside of the ski as required. The climbing aid comprises a pliable, strip-shaped support layer having a first longitudinal end for connection to the front tip portion of the ski and a distal distal further longitudinal end, wherein the length of the support layer substantially corresponds to the length of the ski. This climbing aid has an adhesive side, which is provided for adhesive assignment to the underside of the ski. At the opposite side of the adhesive side flat at least one Rückgleithemmender Steighilfeabschnitt and at least one a comparatively higher lubricity exhibiting sliding portion is formed. The ski has in this case a front, bent-up front portion, which does not contact in the unloaded state of the ski with a flat surface, with this bent front portion extends over a ski longitudinal section between 20% and 50% of the ski length. In combination, the sliding section extends the climbing aid starting from its first longitudinal end at least over a longitudinal section between 20% and 50% of the length of the base course and at the same time over the entire width of the base course. With regard to the longitudinal direction of the support layer, at least one riser section at least partially covering the support layer is formed following this front sliding section of the climbing aid.

The measures according to the invention have the advantage that an optimized behavior of the climbing aid per se, but also of the set of climbing aid and ski in relation to ascent phase and departure phase is achieved. Above all, the specified, coordinated combination of ski and climbing aid achieves these advantages. In particular, the as needed releasable climbing aid according to claim 1 or 2 offers the advantage of a good gradeability Steighilfemittels. In addition, it is possible to remove the corresponding climbing skin for longer runs, especially for extensive deep snow descents, from the ski body entirely, so as to use the optimum sliding conditions of the original outsole, especially the tread of the ski. For shorter sections or downhill sections between individual ascent passages, it is also possible to leave the climbing aid on the underside of the ski and to achieve the best possible gliding and thus a force-saving locomotion in these phases. It is thus achieved during the ascent with such a Steighilfemittel a favorable ratio between climbing ability or Rückgleithemmung and lubricity to overcome relatively short sloping, or almost flat terrain sections.

A significant advantage of the design or combination according to the invention lies in the fact that a relatively effortless ascent in conjunction with skis with a relatively large blade section can be achieved. Such skis with a relatively large, front blade section are often referred to as skis of the "rocker" type. The specified climbing aid offers, especially in connection with touring skis of the type "Rocker" a possible power saving climb. In such "rocker touring skis" or mountaineering skis in rocker design, the front section or the extensive blade section of the ski body comes into contact with the ground mainly via the sliding section of the climbing aid in the course of a walking step. When pushing forward the ski together with the attached below climbing aid of the specified ski in the course of a walking step so inhibited as little as possible, so that a relatively smooth progress through mutual pushing forward the skis of a pair of skis is guaranteed. Since during the ascent in many of the forward steps of the blade area of a pair of relatively relatively long scooped blade or relatively weitreichendem blade section (so-called rocker design) relatively often or relatively far into contact with the ground, especially with the snow, in these sections the climbing aid but has a relatively high or relatively good lubricity, the total amount of effort required in the course of an ascent using the specified climbing aid is reduced. In addition, the specified climbing aid provides good grip or sufficiently high security against slipping back, after which mainly the subsequent section of the blade is responsible or comes into its own.

Thus, with the measures according to the invention an optimized compromise between climbing ability or Rückgleithemmung and lubricity or energy saving achieved. After the sliding portion of the specified climbing aid for wetting is usually less prone than one consisting of a plurality of hairs climbing section, with the inventive solution beyond a weight advantage can be achieved, in particular over embodiments in which the blade area over the entire surface with a through a climbing skin provided climbing aid is provided. But even with short descents in deep snow, the inventive measures offer advantages in terms of optimized lubricity and thereby achievable higher sliding speed. In addition, due to the provided with sliding surface, relatively large blade section and the rise in undrilled deep snow can be somewhat facilitated, which benefits in particular a previous user, which is responsible for tracking in deep snow, in terms of power conservation and ease.

The riser section can extend without interruption with respect to its longitudinal direction starting from the front sliding section, in particular starting from the rear end of the front sliding section, to the further longitudinal end of the supporting layer. As a result, that portion which is subjected to the heaviest loads during ascent is provided with material that hindlaps, whereby the performance in terms of climbing ability or climbing behavior is favorable.

It is expedient if the climbing support section extends within a contact area of a user, in particular in the area of the binding mounting or shoe contact zone with respect to the ski, over the entire width of the supporting layer or of the ski. In particular, it is advantageous if the climbing aid section extends with the anti-rebar means within the shoe contact zone or in the region of the ski binding mounted on the ski over the entire width of the ski. As a result, those sections which are responsible for one-sided exposure to the body weight of the user for an intensive Rückgleithemmung provided as large as possible with Rückgleithemmenden means.

It may also be advantageous if a longitudinal extent of the front portion of the ski bent upward and a longitudinal extent of the sliding portion of the climbing aid are dimensioned substantially equal. In particular, it is expedient for the blade or front section of the ski, which has been bent upwards, and the front sliding section of the climbing aid, which is substantially congruent or correspondingly positioned, to have approximately the same length. This creates a favorable behavior or an optimized compromise between the parameters climbing ability and sliding behavior in the course of the ascent or in the course of descents with mounted climbing aid.

It is also expedient if the longitudinal extent of the sliding portion of the climbing aid is dimensioned such that it ends in the vicinity of the front contact point or the front contact point of the tread of the unloaded ski against a flat surface. Alternatively, the sliding portion of the climbing aid, starting from the first or front longitudinal end of the ski towards the further or rear longitudinal end of the ski slightly before the closest in relation to the ski tip, front contact point of the tread or outsole to a flat surface. Also, this is a favorable ratio between achievable climbing ability and sliding behavior of the combination of a ski according to the so-called rocker type and the appropriately trained, thus combined climbing aid achieved.

In addition, the climbing section of the climbing aid may comprise two spaced apart Steighilfestreifen which are respectively associated with the longitudinal side edges of the support element and the lateral edge elements of the ski. As a result, the total amount of rückbelithemmendem material is reduced or minimized, but also when crossing or Traversing of hillside sections sufficient backlash is guaranteed. In particular, the highest possible proportion of sliding surface is created without significantly impairing the climbing ability.

It is possible that the two spaced apart Steighilfestreifen are located in a transition section between the front sliding portion and the Steighilfeabschnitt. In particular, this creates a transition zone with respect to the longitudinal direction of the ski, which partly has material which hinders the reins and partly has a material which ensures comparatively high lubricity. In particular, this creates an intermediate section in a transition zone between a sliding section which is particularly slippery over the entire width and a climbing section which acts over the entire width, so that abrupt transitions are avoided and a continuous or comparatively smooth transition is created between the corresponding sections.

Furthermore, at least one middle vertical tire which extends in the longitudinal direction of the ski can be formed between spaced vertical tires. This allows an even more harmonious or uniform transition between the sliding section and the climbing section.

According to a development it is provided that two further, spaced-apart Steighilfestreifen are formed, which extend starting from a Steighilfeabschnitt which extends within a contact area of a user over the entire width of the support layer or the ski to the other longitudinal end of the support layer. As a result, the ratio or the interaction between climbing ability and sliding behavior with respect to forward movements can be further optimized.

In particular, the riser section may have a substantially I-shaped or H-shaped outline in plan view of the flat side. This also creates a shape or a course of Rückgleithemmenden sections, which on the one hand provides a basis for a lightweight construction as possible and on the other hand ensures a good relationship between back-inhibiting effect and slidability in relation to the desired direction of travel.

It is expedient if the climbing-aid section extends with respect to the longitudinal extent of the climbing aid over the remaining longitudinal section not occupied by the front sliding section, in particular if a longitudinal extent amounts to between 50% and 80% of the length of the supporting layer or of the ski. Thereby, that portion of the climbing aid or the ski, which is actively or relatively intensively pressed against the ground, provided with the Rückgleithemmendem means whereby the effect of the climbing aid is as high as possible.

The previous definitions or proportions refer to the developed length compared to a flat background. This is the most effective in terms of effectively effective length and width ratios.

The climbing aid section is expediently formed by a pile, in particular by a fur or plush section with uniformly aligned hairs or bristles. In particular, the tips of the hairs or bristles point in the direction of the rear end of the ski. The effective surface of the climbing aid section may be arranged projecting relative to a sliding surface of the at least one sliding section, so that the effect of the climbing aid section is high or as effective as possible.

In order to achieve increased sliding of the at least one sliding portion of the climbing aid, the sliding portion may be formed of plastic or provided with a plastic layer.

The base layer is expediently formed from a woven fabric, in particular from a textile fabric or other sufficiently stretch-resistant, dimensionally flexible and tear-resistant backing material.

Finally, it may also be expedient if the at least one sliding section of the climbing aid is formed by a plastic which is flowable and subsequently hardening in the processing state and which is applied to the carrier layer and forms a sliding surface. As a result, a particularly good sliding behavior can be achieved and at the same time the production costs can be kept as low as possible.

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 throughout the description are transmitted mutatis mutandis to the same parts with the same reference numerals or component names can. Also, the position information selected 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.

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 sub-areas 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 4 is an embodiment of a ski 1, in particular a so-called touring or Mountaineering ski schematically and exemplified. This ski 1 is to be used in pairs and designed especially for the practice of touring skiing or hiking. In the course of practicing the ski tour or the so-called ski mountain hiking, it is typical that follow longer periods of ascent longer departure phases, especially downhill in deep snow are desired and sought. The locomotion takes place so far away from groomed trails or groomed slopes, which is a contrast to cross-country skiing or classic alpine skiing.

For the sake of clarity, only a single ski 1 of a pair of pairs to be used was shown. In addition, for the sake of simplicity, the per se known, to be mounted on the top of the ski body binding device, in particular a standard touring ski binding with a Schwenkverbindungsmöglichkeit a sports shoe against the ski body, not shown in the drawings. The binding mounting zone 2 and the shoe contact zone 3 at the top 4 of the ski body was schematically indicated by dashed lines. The shoe footing center 5, symbolized by a dot-dash line, relative to the ski 1 is, as known per se, eccentrically provided with respect to the overall ski length, in particular positioned with respect to the overall length of the ski body within its rear half. Accordingly, the on the The usual direction of travel direction, front ski section between the shoe footprint center 5 and the ski tip 6 comparatively longer than the rear ski section between the shoe footprint center 5 and the rear with respect to the usual direction of travel Schiende. 7

In order to facilitate the overcoming of terrain slopes, a climbing aid 8 is provided, which is formed for releasably attaching to the underside 9 of the ski 1 as required. The bottom 9 of the ski 1 is characterized by a standard tread 10 - Fig. 4 - Formed, which offers the best possible sliding against the respective surface, especially on snow or ice. The tread covering 10 is preferably delimited along its lateral longitudinal edges by edge elements 11, 12, in particular by so-called steel edges. The tread covering 10 itself is preferably made of plastic, in particular of polyethylene, and defines the lower end or the lower boundary surface of the ski body. The underside 9 of the ski 1 is carried out with the exception of a possibly provided rut of marginal depth, in particular a depth of less than 2 mm, planar or planar. This means that the running surface covering 10 or the underside 9 of the ski 1 preferably has no grooves, cutouts or other recesses. The structurally independent climbing aid 8, which can be coupled with the ski 1 or connected to a unit if necessary and if necessary from the ski 1, in particular from the bottom 9, again removed or removed, is relatively limp and largely strip-shaped executed. The climbing aid 8 is thus zusammenrollbar or collapsible to be stored as compact as possible in the transport or storage condition or to be transported easily and space-saving in a backpack of the user.

The need-releasably attachable climbing aid 8 preferably forms an adhesive side 13 on its side facing the tread surface 10 side. In particular, the adhesive side 13 is formed by a full-surface or at least partially formed adhesive layer 14, which is a multiple adhesive connection and removal of the climbing aid 8 relative to the ski 1 or against the tread covering 10 made of plastic allows. In particular, this adhesive layer 14 has permanently self-adhesive properties, so that the climbing aid 8 is repeatedly applied to the outsole or to the tread surface 10 of the ski 1 glued and removed again. As an equivalent effect to such an adhesive layer 14 is to be understood as another bonding layer, which is based for example on the principle of suction effects, on the principle of non-chemical adhesion effects or on the principle of finest micro-compounds. The adhesive side 13 may thus have, in addition to sticky or adhesive properties, also other, an adhesion to the bottom 9 of the ski 1 scoring agent. The adhesive side 13 serves primarily to ensure that the climbing aid 8 also rests as gap-free as possible in the convexly extending section of the tread covering 10 or, in the long term, remains firmly attached to the tread covering 10 during active use. In particular, this is a gradual accumulation of snow or ice between the climbing aid 8 and the tread 10 are held back.

Preferably, at least one longitudinal end 19, 20 of the climbing aid 8 by means of a mechanical coupling device with the respective nearest end portion of the ski 1, if necessary, releasably coupled. Conveniently, at least at the front longitudinal end 19 of the climbing aid 8, a mechanical coupling element is formed in order to be releasably coupled to the front end portion, in particular with the ski tip 6, if necessary. As a result, the security against unwanted detachment during use of the climbing aid 8 is increased. The at the front and / or rear longitudinal end 19; 20 provided coupling element can be formed in a conventional manner by hooks, brackets, bolts or extensions, rubber straps, buckles, magnetic fasteners and the like.

One of the adhesive side 13 opposite flat side 15 of the climbing aid 8 has at least one Rückgleithemmenden Steighilfeabschnitt 16 and at least one a comparatively higher lubricity sliding portion 17 on. The rising-aid section 16 has an anti-backlash effect, while the sliding section 17 has a maximum possible sliding in any direction relative to the respective ground, in particular with respect to snow or ice.

How best from a synopsis of Fig. 3 . 4 8, the climbing aid 8 comprises a pliable, strip-shaped support layer 18 having a first longitudinal end 19 for connection to the front tip section of a ski 1 and a distal longitudinal end 20, the length of the support layer 18 being substantially equal to the length of the track Schis 1 corresponds. The support layer 18 is designed sufficiently tear-resistant and represents the strength-relevant element of the climbing aid 8. The support layer 18 may be formed by a fabric or by another, sufficiently tensile or tear-resistant and as flexible as possible formable material.

The sliding portion 17 of the climbing aid 8 extends from the first longitudinal end 19 over a longitudinal section between at least 20% and a maximum of 50% of the length of the support layer 18 and at the same time preferably over the entire width of the substantially strip-shaped support layer 18. In particular, it is expedient if the Length of the sliding portion 17 in the front, the ski tip 6 attributable end portion of the climbing aid 8 between 20% and 50%, preferably between at least 25% and up to 40%, preferably in about 33%, the length of the climbing aid 8 and the length of attributable Schis 1 is.

In addition, with regard to the longitudinal direction of the support layer 18, following this sliding section 17, at least one riser section 16 at least partially covering the support layer 18 in the width direction is formed. This with respect to the usual direction of travel to the sliding portion 17 subsequent Steighilfeabschnitt 16 extends in relation to the longitudinal direction of the support layer 18 preferably without interruption to the other longitudinal end 20 of the support layer 18, as shown in the Fig. 1-3 was exemplified.

The specified climbing aid 8 is particularly effective or efficient in conjunction with a specially designed or geometrically shaped ski 1 according to the so-called "rocker type". Such Schiki structures are also called "reverse camber" or "zero camber" and "banana". Such Schigeometrien provide good buoyancy in deep snow, making them well suited for the specified in the subject property right touring or Mountaineering Schier 1. "Reverse camber" essentially means negative bias and this is actually the oldest shark form. In these skis with negative bias, the ski center may also rest more or less flat. In any case, the front front portion 21 of the described in this patent "rocker skis" or the front blade portion of a generic ski 1 a relatively long approach, starting from the shoe foot center 5 toward the ski tip 6 relatively soon or more upwards bulges. That is, a generic ski 1 a has relatively distinctive or pronounced blade or front portion 21, as shown in the Fig. 1 . 2 was illustrated schematically and exemplified.

In particular, the initially described advantageous interactions are achieved by a combination of the specified climbing aid 8 in conjunction with a ski 1 according to the "rocker type". In particular, the climbing aid 8, which is formed with at least one rising auxiliary section 16 and partially with at least one sliding section 17, can be used or used advantageously in those skis 1 which have a relatively large, upwardly bent front section 21, as shown in FIGS Fig. 1 . 2 has been shown schematically. The at a Rocker ski 1 in comparison to a classic alpine or Pistenschi relatively far reaching, bent up upward front portion 21 is that portion of the ski body, which is not contacted in the unloaded condition of the ski 1 relative to a flat surface 22. With respect to the entire length, in particular to the unwound or projected ski length 23, this bent-over front section 21 extends over a ski longitudinal section between at least 20% and 50% of the ski length 23. In particular, a length of the upwardly pointing blade or front section 21 of Schi 1 between 20% and 50%, preferably between at least 25% and up to 40%, preferably in about 33%, the length of the ski 1 amount.

In any case, such a ski 1 according to the so-called "rocker type" on a relatively early onset, gradually increasing, front blade or front portion 21, which improves performance in the course of downhill skiing in deep snow. In particular, this relatively far-reaching blade or front section 21, which occupies more than 20% of the ski length 23, achieves an optimized buoyancy for the front section of the ski body and thus undesired sinking or so-called digging of the ski tip 6 in the soft snow or snow in the deep snow. This convexly curved front section 21 with respect to the underside 9 or in relation to the running surface may amount to between 20% and 50% of the ski length 23, in particular approximately 33% of the ski length 23.

The upwardly curved front portion 21 of such rocker skis 1 can also be defined differently. In particular, this front portion 21 is formed by that longitudinal portion of the ski 1, which extends between the front contact or support point 24 of an unloaded ski 1 with respect to a flat surface 22, in particular one with the body weight of a user not loaded ski 1, to the front ski tip 6 extends. This front contact or support point 24 - according to Fig. 1 . 2 - Is at least 20% to about 50%, often in about 33%, the ski length 23, starting from the front ski tip 6 in the direction of the rear ski 7 distanced.

An optionally provided pretensioning height 25 of the ski 1 is greatest in the area of the binding mounting zone 2 or in the area of the shoe contact zone 3, as in FIG Fig. 2 was presented. The rear contact or support point 26 of the underside 9 of the ski 1 with respect to a flat surface 22 is positioned relatively closer to the rear ski 7 compared to the front contact point 24 or in relation to the longitudinal extent of the blade side front portion 21 , In about midway between the front and rear contact or support point 24, 26, the shoe contact center 5 may be provided.

How best from a synopsis of Fig. 1 to 3 can be seen, a longitudinal extent of the upwardly bent-up front portion 21 of the ski 1 and a longitudinal extent of the sliding portion 17 of the needily releasably attachable climbing aid 8 may be substantially equal and be aligned with respect to the positioning in the longitudinal direction 23 substantially congruent. The longitudinal extent of the sliding portion 17 of the climbing aid 8, in particular the rear longitudinal end of the sliding portion 17 with respect to the usual direction of travel, can be in the vicinity of the front contact point 24 or at the front contact point 24 of the tread 10 of an unloaded ski 1 with respect to a flat surface 22 end. Without losing striking effect, it is also possible that the sliding portion 17 of the climbing aid 8, starting from the first longitudinal end 19 in the direction of the further longitudinal end 20 of the support layer 18 and the ski 1 slightly before this closest to the ski tip 6, front contact or Support point 24 ends.

It is essential that with respect to the longitudinal direction of the support layer 18 or of the ski 1 following this front sliding portion 17 of the climbing aid 8 at least one riser section 16 at least partially covering or covering Steighilfeabschnitt 16 is formed with Rückgleithemmender effect.

According to an expedient embodiment, it is provided that the upright auxiliary section 16 with respect to the longitudinal direction of the climbing aid 8 or with respect to the longitudinal direction of the support layer 18 starting from the front sliding portion 17 without interruption or largely interruption to the other or rear longitudinal end 20 of the support layer 18th extends. Slight longitudinal interruptions or smooth end sections in the climbing section 16 are to be regarded as largely uninterrupted.

The support layer 18 or the strength-relevant layer of the climbing aid 8 can, as in Fig. 3 illustrated having parallel, lateral boundary edges. Likewise it is possible, as in Fig. 6 is indicated to provide 8 lateral boundary edges in the climbing aid, which are either completely adapted to the sidecut or side contour of the ski 1 or at least partially adapted.

As further in the embodiment according to the Fig. 5, 6 has been illustrated, it is also possible that the riser section 16 comprises two spaced apart Steighilfestreifen 27, 28, which are each associated with the longitudinal side edges 29, 30 of the ski 1. It is expedient to form these two spaced-apart, lateral Steighilfestreifen 27, 28 in a transition section 31 between the front sliding portion 17 and the Steighilfeabschnitt 16. The two spaced-apart Steighilfestreifen 27, 28 may be substantially V-shaped or divergent to each other, as in the front portion of the Steighilfeabschnittes 16 according to the Fig. 5, 6 was presented.

It is also possible - Fig. 6 - Form two further, spaced-apart Steighilfestreifen 27 ', 28, which extend starting from the Steighilfeabschnitt 16 to the other or rear longitudinal end 20 of the support layer 18, as in Fig. 6 was exemplified. A between the lateral Steighilfestreifen 27 ', 28' preferably formed sliding portion 17 'has either parallel, lateral boundary edges or mutually V-shaped extending boundary edges, as in the front end portion of the Steighilfeabschnittes 16 according to Fig. 6 was presented. The climbing support section 16 may be located at least within a contact area of a user or congruent to the footwear zone 3 - Fig. 1 - Preferably over the entire width of the support layer 18 and the ski 1 extend.

According to an optional further development, at least one longitudinally extending middle stiff-riding tire 32 may be formed between the spaced-apart high-lift tires 27, 28, as shown in FIG Fig. 6 indicated in dashed lines.

It is practicable if the Rückgebehemmende Steighilfeabschnitt 16 of the climbing aid 8 has a substantially U-shaped or I- or H-shaped outline in plan view or with respect to the substrate 22 to be assigned flat side 15, as shown in Fig. 6 was exemplified.

It is expedient if the rising aid section 16 of the climbing aid 8 extends with respect to its longitudinal extension over the remaining, not covered by the sliding portion 17 longitudinal portion of the support layer 18. Accordingly, the longitudinal extent of the climbing auxiliary section 16 is between 50% and 80% of the length of the base layer 18 or of the ski to be allocated. The previously mentioned ratios or proportions relate mostly to the total length of ski 23, the length of ski 23 being defined by the unwound length in relation to a flat ground 22.

How best that Fig. 7, 8 can be seen, the riser section 16 is preferably formed by a pile 33. Such a known pile 33 has a plurality of reverse hemming acting hairs 34. How best Fig. 7 can be seen, an effective or Rückgleithemmende surface of the Steighilfeabschnittes 16 against a sliding surface 35 of the at least one sliding portion 17 and 17 'protruding or protruding. This means that the tips or the free ends of the hairs 34 protrude with respect to the effective sliding surface 35 of the at least one sliding section 17, 17 '.

The at least one sliding portion 17 of the climbing aid 8 may be formed of plastic. In contrast, the support layer 18 is advantageously formed from a textile fabric or other carrier material. But it may also be the support layer 18 formed of plastic.

The at least one sliding layer 36 of the climbing aid 8 may be formed by a flowable in the processing state and subsequently curing plastic, which on the Supporting layer 18 is applied and so the at least one sliding surface 35 and the sliding layer 36 of the climbing aid 8 is formed.

According to the execution Fig. 9 it is also possible that the pile 33 or its hairs are anchored in the support layer 18 or on the surface of the support layer 18. In this case, the sections 33 of the support element which are recessed from the pile 33 or from the hairs define the at least one sliding section 17 of the climbing aid 8. The sliding or wear resistance of the at least one sliding section 17 can be determined by a friction-reducing coating or by a sliding layer 36 applied to the support layer 18 Plastic be improved.

In Fig. 10 is the function or action of the climbing aid 8 or the combination of climbing aid 8 and a generic Schi 1 or Schi pair of the type "Rocker" illustrated schematically. It can be seen that the front, upwardly curved front portion 21 of the Skier 1 of the type "Rocker" comes under load with the body weight of the user either not or only marginally in contact with the ground. In the illustrated moment, the right ski 1 of the user is almost loaded with the entire body weight. The front front portion 21 of the Rockler ski 1 does not or hardly touch the ground, so that a Rücklgeithemmendes agent in this front portion 21 on the bottom 9 of the ski 1 would not or only slightly appropriate. Rather, a Rücklgeithemmendes agent in the convex upward curved front portion 21 may cause increased costs or a higher weight of the climbing aid 8.

In contrast, it may happen that the ski 1 raised in the course of a step (at the moment shown the left ski 1 of the user) rests with its front front section 21 against the ground 22 or contacts the ground. In the course of this walking step, the (left) ski 1 must be pushed forward or upwards with the climbing aid 8 attached to the underside 9. The sliding portion 17 of the climbing aid 8, which is assigned approximately to the front, upwardly curved front portion 21 of the ski 1, thereby favors a more force-saving locomotion, since the sliding friction against the substrate 22 is reduced in these phases of walking steps. This is especially in overcoming slopes or in deep snow beneficial for the user of the specified, interacting combination of rocker ski 1 and adapted Climbing aid 8. In the case of continuous sequences of steps, a corresponding change of conditions or states occurs on the left and right skis 1 with respect to the ground 22 of snow or ice.

The exemplary embodiments show possible embodiments of the climbing aid 8 or of the combined ski 1, 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 variation possibility due to the doctrine of technical action by objective invention in the skill of those skilled in this technical field. 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 climbing aid 8 or of the ski 1, this or this part was shown to be incomplete and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.

Above all, the individual in the Fig. 1-4 ; 5 ; 6-8 ; 9 ; 10 shown embodiments form the subject of independent solutions according to the invention. The relevant objects and solutions according to the invention can be found in the detailed descriptions of these figures.
