Description

The invention relates to an end part for the front or rear end of a ski or snowboard and a corresponding ski or a suitably equipped snowboard, as specified in the claims 1, 2 and 35.

End parts or end elements for the front or rear end of skis or snowboards are basically known from the prior art. These end parts mainly perform the function of a trim element for the tip or end portion of the corresponding sliding board body. In particular, such end parts are mounted mainly for production reasons in the top or end of a ski or snowboard. Namely, these end parts ensure an optically advantageous conclusion for the sliding board body. In particular, when the gliding board body is constructed as a multilayer composite body or produced by a foam injection method, it is known to provide the end portions of the gliding board body with an end member constituting a trim element. These end parts can already be glued to the gliding board body during the production process and / or are fastened in a form-fitting manner or by means of fastening screws to the end section of the gliding board body. These end parts have fixed dimensions, which are adapted to the dimensions of the respective ski or snowboard. A variable width or thickness is not provided.

From the DE 202 01 963 U1 is a need pluggable extension for the tip or shovel of a ski known. This tip extension can be pushed onto the ski tip if necessary, eg to make downhill runs in deep snow. Subsequently, this slip-on tip, which should bring more buoyancy, especially in deep snow driving, be removed again by the user. This tip extension thus represents an as required assembled and disassembled accessory, which should be mounted on a plurality of skis with different blade geometries. In particular, it is provided that this attachment part fits on the depending on the manufacturer and ski model differently sized front ends of the skis, in particular the blades. For this purpose, the attachment is formed in plan view substantially U-shaped, wherein the distance between the two legs of the U-shaped attachment part can be increased or decreased, in order to be able to be adapted to the respective blade widths of the various ski models.

The present invention has for its object to provide an end portion for the front or rear end of a ski or snowboard, with which the performance, in particular the control behavior of a ski or snowboard, especially a ski or snowboard with variable geometry or varying sidecut can be improved can. Another task is to specify a corresponding ski or a corresponding snowboard.

The first object of the invention is achieved by an end part according to claim 1 or 2. It is advantageous that such an end part improves the control behavior of a ski or snowboard equipped therewith. In particular, this can have a positive effect on the stability of the end section of a ski or snowboard that is variable with regard to the cross-sectional geometry or sidecut. With the end part according to the invention, it is possible either not to obstruct the intended cross-sectional variability at all or to allow a mutual support between the relatively relatively strongly decoupled side edges of a ski or snowboard. In particular, the end part according to the invention represents a link between the left and right to the longitudinal central axis side portions of the sliding board body, whereby the control behavior, in particular the cornering stability of a corresponding ski or snowboard can be markedly improved by the end part. This end part has a multiple function, on the one hand an improvement of the handling characteristics is achieved and further the robustness of the geometrically variable ski or snowboard is increased.

By the measures according to claim 3, a particularly tear-resistant connection of the end portion can be achieved with the respective end portion of a sliding board body, after the side portions of the end portion rigidly and permanently connected to a sliding board body, whereas the central portion of the end portion ensures the required relative adjustability.

By the embodiment according to claim 4 it is ensured that a variable in his blade geometry or in the geometry of the side edges Schneegleitbrett, especially a ski or snowboard, is not or as little as possible hindered in its actuating movements.

In the embodiment according to claim 5 it is advantageous that the lateral sections or the legs of the substantially U-shaped or crescent-shaped end part can be firmly or rigidly connected to the sliding board body, whereas the desired relative adjustability starting from the middle section or from Base portion of the U-shaped or sickle-shaped end part can be done. In particular, instead of a spreading of the lateral sections of the end part, a distance variation starting from the base of the U-shaped or crescent-shaped end part is thereby implemented.

The advantageous development according to claim 6 ensures that the laterally formed to the longitudinal axis sliding surfaces or control edges of the ski or snowboard remain as constant as possible in a common plane. The common plane runs essentially parallel to the sliding surface of the sliding board body. In particular, this avoids that in the so-called "carving" or when driving on the edge, a height offset between individual sliding board tongues or Gleitbrettteilabschnitten occurs in the front and rear end portion of the sliding board body. The control or cornering behavior of a longitudinally or partially slotted sliding board body can thus be significantly improved via the specified end part, which also serves as a guide member.

Due to the embodiment according to claim 7 instead of a relative adjustability between two or more elements, an elastic extensibility and recoverability of the central portion is utilized, so that the end part can adapt by elastic deformability to varying width ratios.

The embodiment according to claim 8 enables the construction of a structurally compact end part, wherein such an end part can hardly be blocked in its compensatory movements or in its width variability by snow or ice.

By the measure according to claim 9, the end part can be produced relatively inexpensively. It also simplifies inventory management by requiring only a single component to form the front and rear end portions of a ski or snowboard.

In the embodiment according to claim 10 it is advantageous that the end part consists in its lateral sections or along its legs of relatively hard material and thus can be attached particularly advantageously to a corresponding sliding board body. The middle section, however, is formed of elastomeric or soft elastic plastic and thus ensures a distance variability within the base portion of the U-shaped or sickle-shaped end portion.

In the embodiment according to claim 11, it is advantageous that the end part can be built up as reliably as possible in the most cost-effective and long-term manner.

Also by the measures according to claim 12, a width variation of the end part can be achieved without causing a relative adjustment between structurally independent elements. Thus, glide surfaces susceptible to icing can be avoided and a proper function is ensured even under the most adverse conditions of use. In addition, with a shape and material-related elasticity, for example. In the manner of a pleat assembly, a high maximum adjustment can be achieved without causing the central portion of the end portion is exposed to high loads or tensile forces. In particular, a material fatigue is kept behind after numerous cycles of motion.

The embodiment according to claim 13 allows a weight-optimized design. In addition, an increased personal protection is achieved by the tip or end of the sliding board body is performed as blunt or rounded.

The embodiment according to claim 14 provides increased personal protection after the front end of the gliding board body is thickened and / or comparatively soft-elastic and / or executed with rounded edges. In addition, this is a permanent protective measure created, which requires no special maintenance or adaptation activities on the part of the end user.

The embodiment according to claim 15 ensures that a geometrically or cross-sectionally variable end section of a ski or snowboard has a visually appealing conclusion. In addition, this reduces the risk of delamination of a multilayer structure of the respective sliding board body.

By the measures according to claim 16, the respective sections of the end part are rigid and thus relatively torn off with the sliding board tongues of Gleitbrettkörpers connectable. In addition, the planned width or distance variation between the lateral portions of the end portion can be implemented over the central portion of the end portion.

The advantageous development according to claim 17 ensures that the end part has a resilient return means, which tends to be always transferred to a defined starting or rest position as soon as the forces acting from outside have been eliminated. This active, elastic recovery promotes the driving behavior of equipped with such an end part ski or snowboard. In a particularly advantageous manner, this elastically extensible and recoverable bridging element can also form a guide device for suppressing vertical deviation movements between the sliding board tongues of a split or longitudinally slotted ski or snowboard.

By the measures according to claim 18, an end portion is created, which can fulfill the scheduled function during the average duration of use of a so equipped ski or snowboard. Moreover, such an end portion provides sufficient travel such that the end portion does not hinder the manually presettable and / or the deflection dependent width variation of the blade end portion of a gliding board body.

Another advantage is also an embodiment according to claim 19, as a fall below a minimum distance provided between the two sliding board tongues slit in the longitudinal direction Gleitbrettkörpers be simply but effectively prevented can. In particular, this ensures that even with strong approach forces between two sliding board tongues, as occurs for example when driving on one of the lateral control edges, a defined minimum distance between the sliding board tongues is guaranteed.

By the embodiment according to claim 20, a stop element is provided, which at the same time forms a barrier element or represents a protective element for an optionally formed within the gap of a sliding board body, stretchable bridging element. In particular, this extension then fulfills a protective function for the soft-elastic or rubber-elastic bridging element, which bridges the gap between the first and second sliding board tongue of a sliding board body. The robustness of a geometry or waist variable ski or snowboard can be increased again.

Due to the configuration according to claim 21 a rising with increasing time fatigue of the elastically extensible and recoverable bridging element is at least partially avoided.

By the measures according to claim 22, a robust end portion is ensured, which can also be particularly reliable or tear-resistant connected to the respective end portion of the sliding board body, when the end part is structurally narrow or structurally relatively compact.

Of particular advantage is also an embodiment according to claim 23, characterized in that a central element or central part is constructed, which always remains centrally positioned. In particular, the middle part is thereby retained in an unchanged relative position with respect to a sliding board body, while the lateral portions of the end part can be moved relative to the central middle part. This ensures that, starting from a positionally defined middle section, the two lateral sections of the end section can be moved apart and approached one another.

Due to the configuration according to claim 24 various middle parts can be optionally positioned on the bridging element. In particular, this means in a simple manner middle parts with leadership function and / or middle parts with

Damping function between the two lateral sections of the end part interchangeable or easy to install mounted.

The embodiment according to claim 25 ensures that the central part remains centrally held when the lateral sections of the end part are moved in the direction of the central part or moved away from the central part.

By the measures according to claim 26, a stable and tear-resistant mounting of the central part is achieved on the elastically stretchable and recoverable bridging element.

By the measures according to claim 27 unwanted relative movements between the first and second portion of the end part can be reliably prevented. In particular, deviation movements between the first and second sections with respect to a direction extending vertically to the lower or upper side of the end section can thereby be suppressed.

By the measures according to claim 28, a spring element is created, which has a high robustness and is structurally simple. In addition, the required parking spaces can be accomplished without the need of structurally complex or structurally voluminous coil springs.

Another advantage is also an embodiment according to claim 29, since a possibly leitgewichtiger and cost-end part can be constructed.

In the embodiment according to claim 30, it is advantageous that such a spring element is particularly robust and, moreover, can assume an exact guiding function for suppressing unwanted relative movements between the sections of the end part.

By the measures according to claim 31, the elastically extensible and recoverable bridging element fulfills a dual function, whereby the number of required components is reduced and the weight of the end part can be kept low. Due to the configuration according to claim 32, a gap formation in the central portion of the end portion is avoided. As a result, mutual jamming or entrapment of foreign bodies or the formation of icing between the mutually adjusting sections of the end part can be avoided.

By the measures according to claim 33 spreading or narrowing of the blade or end portion of the sliding board body are made possible without the end part opposes such manually preset and / or load-dependent controlled and / or deflection-controlled movements blocking or suppressing resistance.

In the measure according to claim 34 is of advantage that a robust, structurally but nevertheless simple guide device is constructed, which favors the leadership or control behavior of equipped with such an end part ski or snowboard. In addition, by such a configuration, the tip or base region of the U-shaped or crescent-shaped end part can be closed or bridged, so that the gap or a fold element possibly bridging this gap is better protected against damage. In particular, this reduces the likelihood or avoids the risk that hard foreign bodies or ice lumps or the like may enter the gap between the two sliding board tongues starting from the front end section of the sliding board body.

Regardless of the object of the invention is also achieved by a ski or a snowboard according to claim 35. Thus achievable advantages and technical effects can be found in the previous description parts. It is advantageous, furthermore, that such a gliding board body offers increased personal protection, after the top and end sections thereof are at least partially covered or covered by means of the end part.

An exceptional driving behavior of the sliding board body is achieved if it has a geometry influencing means for changing the cross-sectional geometry or changing the waisting, as stated in claim 36.

Another advantage is also an embodiment according to claim 37, since a ski or snowboard is created, the sidecut or cross-sectional geometry can be changed in a particularly simple and yet effective manner. In addition, the geometry of such a ski or snowboard with relatively low actuating forces can be influenced sufficiently striking.

Finally, an embodiment according to claim 38 is also advantageous because it makes it possible to markedly improve the sliding behavior or the suitability of the gliding board body.

The invention will be explained in more detail below with reference to the embodiments illustrated in the drawings.

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 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.

In the Fig. 1 and 2 is a Schi 1 illustrated, which in the front and / or in the rear end portion has a technically improved end portion 2, 2 '. Of course, this end part 2, 2 'can also be used at the front and / or at the rear end of another, sliding board body, in particular on a snowboard, a mono ski or a similar snow gliding board.

The end part 2, 2 'according to the invention is intended primarily for skis or snowboards which have at least one geometry-influencing means 4 for changing the width or the waisting and / or the cross-sectional geometry of the front and / or rear end section of the sliding board body 3. This geometry influencing means 4 preferably comprises at least one slot, gap 5, 5 'or another weakening or splitting of the cross section of the gliding board body 3 on the gliding board body 3. This cross-sectional weakening, which in the form of a slit or slit 5, 5' corresponds to the illustrated embodiment. In this case, this weakening of the cross-section of the gliding board body 3 achieved either by a plurality of aligned apertures or slits or partial slits runs starting from at least one end of the gliding board body 3 in the direction of Preferably, both the front end portion and the rear end portion of the sliding board body 3 are designed to be slotted, these cross-sectional weakenings starting from the two ends in each case towards the central portion of the Gleitb Rescue body 3 run. Expediently, these cross-sectional weakenings end in each case at a predetermined distance in front of the mounting section for a binding device 3a for on-demand coupling with the foot of a user.

It is essential that the end parts 2, 2 'described in detail below are used for skis 1 or snowboards whose width in the blade area and / or in the rear end area is variable depending on the load and / or individually presettable by a user. With regard to the technical feasibility of this geometry or with respect to the technical implementation possibilities of the geometry-influencing means 4, the detailed disclosure from the Austrian patent applications A 173/2007 and A 174/2007 the Applicant made the subject of this disclosure. Furthermore, the disclosure of EP 1 297 869 B1 made the subject of this disclosure.

The end portions 2, 2 'described below are particularly provided for those embodiments of geometrically variable skis 1 or snowboards, in which a width variation of the front and / or rear end portion by at least one longitudinal incision or slot in the front and / or rear end portion of the sliding board body 3 is accomplished. The end part 2, 2 'is designed in such a way that it can follow the load-dependent variable and / or the width variations of the respective end section of the gliding board body 3 that can be preset individually by the user and at the same time achieve the performance achievable with such a ski or snowboard, in particular its driving. or positively influenced tax behavior. The end portions 2, 2 'can contribute significantly to increasing the torsional rigidity of the front and / or rear end portion of the sliding board body 3, whereby their driving or control behavior is positively influenced. In particular, in the formation of slots or columns 5, 5 'in the sliding board body 3, the end portions 2, 2' act as a load-transmitting coupling or stabilizing element between the individual tongues or legs in the front and / or rear end portion of the sliding board body 3. That is, the torsional rigidity of adjacent sliding board tongues 23, 24 and 23 ', 24' and the front and / or rear end portion of the gliding board body 3 can be significantly increased by the end parts 2, 2 ', respectively. This in turn results in a more precise controllability or in an improved cornering behavior of the sliding board body 3.

As best of the enlarged view according to Fig. 2a it can be seen, the at least one slot or gap 5, 5 'in the sliding board body 3 is preferably bridged with at least one flexible bridging element 5a. This flexible bridging element 5a is designed so that it can follow the occurring geometry or distance variations in the respective end portion of the sliding board body 3 and a transition of snow or ice from the bottom of the sliding board body 3 towards the top of the Gleitbrettkörpers 3 prevents. Further technical details are the Austrian patent application A 173/2007 the Applicant, which application is made the subject of this disclosure.

In order to meet the above-mentioned requirements, the end part 2, 2 'at least a first and a second section 6, 7, wherein the position or relative position of the first portion 6 relative to the position of the second portion 7 is variable. The end parts 2, 2 'can be made in one piece, i. be formed by a single part or element which forms the two lateral sections 6, 7. The end parts 2, 2 'can also be designed in several parts, in which case the individual sections 6, 7 are integrally connected. Both embodiments, i. the one-piece design and the multi-part one-piece design will be described in more detail below. In principle, the first and second sections 6, 7 could also each represent independent structurally independent end or end parts for the at least two tongues or legs in the front and / or rear end section of the sliding board body 3.

The first lateral section 6 of the end part 2, 2 'has a zone 8 which is adjacent to the second lateral section 7 of the end part 2, 2'. The second section 7 of the end part 2, 2 'has a zone 9, which is the immediate vicinity of the first section 6 and the first section 6. The mutually facing zones 8, 9 of the sections 6, 7 may in this case be designed on structurally independent sections 6, 7 or else be formed on a one-part end section 2, 2 'with a continuous or interruption-free transition section between the zones 8, 9, like this for example Fig. 7 is apparent. It is essential that a distance 10, 10 'between the adjacent zones 8, 9 of the first and second sections 6, 7 is variable. That is, the end portion 2, 2 'is variable in width by the zones 8, 9 of the sections 6, 7 are designed to be elastically resilient according to a first embodiment, so that a width or length measure of at least one of the zones 8, 9 changeable is. According to a further embodiment, the zones 8, 9 of the sections 6, 7 extend telescopically into one another or the sections 6, 7 overlap one another. In this case, the first and second sections 6, 7 preferably form a mutual guide device 11 whose guide direction extends transversely to the longitudinal central axis and substantially parallel to the sliding surface of the sliding board body 3.

This displacement distance corresponding to the distance 10, 10 'between the first and the second section 6, 7 of the end part 2, 2' is preferably implemented in the middle section 12 between the outer ends of the end part 2, 2 '. This travel or the variable distance 10, 10 'between the adjacent zones 8, 9 is chosen such that a spread or width increase and a narrowing or width reduction of the outermost end of the sliding board body 3 in a the control behavior of the sliding board body 3' low or noticeable influencing extent can take place. In particular, the end part 2, 2 'is designed such that the distance 10, 10' between the adjacent zones 8, 9 depending on a varying during driving or during use width of the front and rear end of the ski 1 or snowboard is changeable, as this mainly from a synopsis of Fig. 3, 4 is apparent. That is, the end part 2, 2 'is designed in such a way that it is preferably variable in length or width starting from its middle section 12 between the first and second sections 6, 7. This means that a substantially U-shaped or crescent-shaped end part 2, 2 'in plan view changes its width 13 via a telescoping, elastically yielding and / or articulated middle section 12, as will be explained below.

As the embodiment according to the Fig. 3, 4 It can also be seen that the zones 8, 9 of the first and second sections 6, 7 which are closest to one another are positioned within the center section 12 which is related to a width 13 of the end part 2, 2 '.

A guide device 11 between the two sections 6, 7 is preferably formed in the middle section 12. This guide device 11 has at least two telescopically guided or at least two overlapping arranged guide elements 14, 15. The corresponding guide elements 14, 15, which, for example, as a guide pin and thus corresponding guide groove or guide extension 16 and guide recess 17 may be executed, are designed or aligned such that the end portion 2, 2 ', in particular its central portion 12 laterally expandable and recoverable, ie, can be increased and decreased, so that the width 13 of the end part 2, 2 'in dependence of the varying width of the sliding board body 3 is variable. Preferably, this width variation of the end part 2, 2 ', which during the driving operation occurs with the ski 1 or snowboard and / or is individually presettable, starting from the tip region or from the central portion of the end part 2, 2 '.

Instead of the linear guide device 11 described above between the sections 6, 7, it is also possible to form at least the central section 12 of the end part 2, 2 'of an elastomeric plastic 18, in particular of a soft plastic or of rubber. Also, thereby, the width 13 of the end part 2, 2 'in response to a spread angle of the end portion of the sliding board body 3 is variable. Such an elastic central portion 12 made of an elastomeric plastic 18 is shown in the illustration Fig. 7 illustrated. The end part 2, 2 'can also be formed as a one-piece, manufactured in a plastic injection molding process component, whereby the manufacturing or tooling costs can be kept low and also the assembly or storage costs can be reduced.

As further best of the embodiment according to Fig. 7 can be seen, the central portion 12 may be formed of an elastomeric, flexible plastic 18, wherein at opposite edge portions of the central portion 12 each of the first and second sections 6, 7 are attached or formed as side parts 19, 20. In particular, the lateral sections 6, 7 can be injection molded in a multi-component plastic injection molding process. These molded on the elastomeric central portion 12 or integrally molded with the elastomeric central portion 12 side parts 19, 20 consist of a comparatively hard material, in particular of hard plastic, or of a metallic material.

The middle section 12 of the end part 2, 2 'can thus be designed as an elastic expansion section 21, wherein this expansion section 21 ensures a form and / or material-related extensibility and recoverability of the end part 2, 2'. This form- and / or material-based expansion section 21 can be embodied, for example, as an expansion fold arrangement 22 which has at least one elastic expansion fold, as shown in FIG Fig. 11 was exemplified.

The end part 2, 2 'is especially if it is to be used at the front end of a ski 1 or snowboard, in a top view substantially arcuate or crescent-shaped, as the embodiments according to the Fig. 3 to 7 and 12 to 15 can be seen. As a result, material savings for the end part 2, 2 ', but especially weight savings on Gleitbrettkörper 3 can be achieved. Alternatively, it is also possible to provide other geometric contour shapes, for example. Trapezoidal or triangular outline contours for the end portions 2, 2 ', as this is based on the embodiments according to the 8 to 11 is partially illustrated.

The Fig. 3 to 9 and 12 to 15 show various end portions 2, which are provided as a cladding element for the front end face, in particular for the front end portion of a ski or snowboard. That is, these end parts 2 are designed for the tip or the blade of a ski or snowboard. These end parts 2 are provided for a permanent or permanent connection with the front end portion of the ski or snowboard and thus detachably connected to the end portion of the sliding board body 3. For this purpose, positive connections and / or screw and / or adhesive connections are used. Alternatively, it is also possible to partially integrate the end parts 2 during the production of the sliding board body 3, in particular during the hot pressing process, into the structure of the sliding board body 3 or to connect it to the latter.

In the 10, 11 end parts 2 'are exemplified, which are provided as a cladding element for a front-side, rear end of a ski or snowboard. These end parts 2 'or trim elements for the rear end of the ski or snowboard are permanently or permanently connected to the rear end portion of the ski or snowboard. For this purpose, again form-fitting connection mechanisms and / or Schraubbefestigungsmittel and / or adhesives are used or these end portions 2 'also already during the manufacturing process of Gleitbrettkörpers 3 are partially integrated in these.

The two lateral sections 6, 7 of the end part 2, 2 'are permanently connected to a left and right sliding board tongue 23, 24 and 23', 24 'of a sliding board body 3, respectively. The left and right sliding board tongue 23, 24 and 23 ', 24' of the sliding board body 3 is thereby formed by at least one slot or gap 5, 5 'in the sliding board body 3, which runs substantially parallel to the longitudinal center axis and the sliding board body 3 whose upper side at least partially splits or the sliding board body 3 slits at least partially, as best the Fig. 1 to 2a can be seen. The left and right sliding board tongues 23, 24 and 23 ', 24' are thus defined by the at least one incision or gap 5, 5 ', preferably in the longitudinal center plane. In particular, the first portion 6 of the end portion 2, 2 'for permanent attachment to a left to the longitudinal central axis of a ski or snowboard sliding board tongue 23, 23' is provided and the second portion 7 of the end part 2, 2 'is for permanent attachment to a right to Longitudinal axis of the ski or snowboard lying sliding board tongue 24, 24 'is provided.

As the embodiments according to the Fig. 5 to 13 can be seen, the first and second portions 6, 7 of the end part 2, 2 'by means of at least one elastically stretchable and recoverable bridging element 25 connected to each other or elastically coupled together. This coupling between the first and second sections 6, 7 is designed such that the distance 10, 10 'or the relative distance between the first and second sections 6, 7 against the force of the bridging element 25 is variable, in particular enlarged. The force effect of the bridging element 25 is dimensioned such that a change, in particular an enlargement of the spread angle between the adjacent sliding board tongues 23, 24 and 23 ', 24' by means of the geometry influencing means 4 - see Fig. 1 . 2 - remains possible.

The bridging element 25, which may be embodied either as a separate component or as an integral element on the lateral sections 6, 7, is designed such that it withstands up to 15 mm of elastic elongation and recovery without damage. In particular, the bridging element 25 should be able to withstand a travel of up to 15 mm without damage, even after numerous, in particular after hundreds of cycles of movement. A travel of the elastic bridging element 25 or the guide device 11 and / or the elastic expansion section 21 is usually 0 mm to 10 mm, in particular 0 mm to 5 mm.

According to the embodiment Fig. 5 is the elastically stretchable and recoverable bridging element 25 structurally combined with a guide device 11. The force of this elastic bridging element 25 is such that it is a Magnification of the distance 10 elastically yielding resistance opposes and supports a resilient recovery of the sections 6, 7 in a defined initial or resting state, as soon as the forces regarding an enlargement tendency with respect to the distance 10 are omitted. According to the embodiment Fig. 5 the elastic stretchable and recoverable bridging element is injection-molded on the sections 6, 7, in particular within its zones 8, 9, and thereby connected with the first and second sections 6, 7 in a positive or non-positive manner.

In the embodiment according to Fig. 6 the elastically extensible and recoverable bridging element 25 is coupled via positive connections with the first and second sections 6, 7. The bridging element 25 can also act as an elastic buffer element, which dampens approaching movements or oscillations in the approaching direction and / or the distance direction between the first and second sections 6, 7. Here, the elastically extensible and recoverable bridging element 25 is designed as a structurally independent element, which is, if necessary, mountable or, if necessary, replaceably coupled to the sections 6, 7. The elastic bridging element 25 can also act as a resilient tension element, which continuously guides the sections 6, 7 in the direction of reducing the distance 10 or the gap 5, 5 'in the sliding board body 3. Fig. 2a - pretensioned.

In the embodiment according to the Fig. 8 to 10 a bow or bow-shaped bridging element 25 is provided. This bow-shaped bridging element 25 or the corresponding spring element 30 is connected in its end sections via pivot bearings 31, 32 on the one hand with the first portion 6 and on the other hand with the second portion 7 rotatably or articulated. A rotary or articulated axis of these rotary bearings 31, 32 extends substantially perpendicular to the top or bottom of the end part 2, 2 '. The pivot bearing 31, 32 can be designed as a bolt and bush bearing or ball and socket bearing, as in the Fig. 8 . 10 has been illustrated schematically. In particular, 25 cylindrical or spherical bearing elements are at the end portions of the arcuate bridging element executed, which are rotatably mounted in corresponding guide recesses within the first and second sections 6, 7.

Instead of such a pivot bearing 31, 32, it is also possible to connect the elastically stretchable and recoverable bridging element 25 via elastic deformation zones with the lateral sections 6, 7, as best of Fig. 9 is apparent. In particular, while the end portions of the arcuate bridging element 25 are rigidly connected to the sections 6, 7 and constitute the end portions of the bridging element 25, which consists for example of spring steel, the elastic deformation zones.

The bridging element 25 or the guide device 11 or the middle section 12 extends in the embodiments shown either in a straight line or arcuately over a gap or over the region between the sections 6, 7, whereby these components also provide reliable, mechanical protection for an optionally Form existing, elastic bridging element 5a within a gap 5, 5 'in the sliding board body 3, as best the Fig. 1 to 2a can be seen. The end part 2, 2 ', in particular its bridging element 25 and / or its guide device 11 or the middle section 12 between the lateral sections 6, 7 thus also serves as a mechanical damage protection for the relatively fragile, elastic or flexible bridging element 5 a for the gap 5 This is especially of particular advantage when the sliding board body 3 with one of its ends, in particular with the blade or tip against an obstacle, for example against a lump of ice, a pole, a ski pole, a goal bar or Like. The specified end portions 2, 2 'thus also contribute significantly to increasing the robustness of the sliding board body 3, in particular the geometry or waist variable ski 1 or snowboards.

It is essential that the bridging elements 25 according to the Fig. 6 to 11 also act as a guide device 11 or as stabilizing elements. In particular, with these bridging elements 25 a relative adjustability or a vertical displacement between two adjacent sliding board tongues 23, 24 or 23 ', 24' in the vertical direction to the sliding surface or to the underside of the sliding board body 3 is prevented or such deviations movements are opposed to increased mechanical resistance, as this especially in connection with the representations according to the Fig. 1 to 2a is clearly recognizable. The guide device 11 can in fact be implemented with the bridging element 25, in particular by means of the arcuate spring element 30, as the embodiments according to the Fig. 8 to 10 can be seen. This form part of the arcuate bridging element 25, the guide extensions 16, which correspond to guide recesses 17 in the first and second sections 6, 7, to form a mutual guide device 11. Especially the Fig. 8 to 10 It can be seen that portions of the arcuate, elastically deformable bridging element 25 form at least a first guide element 14 which cooperates with at least one further guide element 15 in or on the second section 6, 7 to a mutual guide device 11 between the first and second section. 6 , 7 of the end part 2, 2 'to achieve.

How best Fig. 11 It can be seen that the elastically stretchable and recoverable bridging element 25 can also be formed as a flat steel with at least one expansion fold arrangement 22. The end portions of this metallic, plate or strip-like bridging element 25 are preferably injected into the plastic sections 6, 7 and thereby anchored in these.

As the embodiment according to the Fig. 12, 13 can be seen, between the first and second portions 6, 7 of the end portion 2 at least one stop member 26 for establishing a minimum relative distance or a minimum distance 10 between the first and second sections 6, 7 may be formed. This at least one stop element 26 may be formed by at least one extension 27, which is formed between the facing or adjacent zones 8, 9 of the first and second sections 6, 7. This stop element 26 is dimensioned such that an elastically extensible and recoverable bridging element 25 is present between the first section 6 and the second section 7 with an active stop element 26 in a largely unstretched rest or initial state.

A width of the elastically stretchable and recoverable bridging element 25 is preferably less than half the total width 13 of the end part 2.

As the embodiment according to the Fig. 12, 13 it can be seen further, a middle part 28 can be arranged or held on the elastically extensible and recoverable bridging element 25. This middle part 28 is preferably positively connected to the elastically extensible and recoverable bridging element 25. In this case, the middle part 28 preferably in the central portion of the elastically stretchable and recoverable bridging element 25 connectable to the latter.

According to the illustrated embodiment, the central portion of the elastically stretchable and recoverable bridging member 25 may comprise a block-like support member 29 for holding or receiving the central part 28.

The elastically extensible and recoverable bridging element 25 may comprise a meandering spring element 30, as is apparent from Fig. 12 is exemplified. Like that Fig. 8 to 10 can be seen, the spring element 30 may also be executed arcuate.

The corresponding spring elements 30 may consist of plastic, be formed of spring steel or be constructed by means of another, sufficient elastic properties having material.

In addition to the formation of an independent stop element 26, it is also possible that the elastically stretchable and recoverable bridging element 25 serves as a stop element for limiting the minimum distance 10 between the first and second sections 6, 7, as the embodiments according to the Fig. 5, 6 is removable.

According to the execution in the Fig. 12, 13 can the middle part 28 also be designed such that it engages positively with its lateral edge sections in the mutually facing front ends of the first and second sections 6, 7 or that the central part 28 bridges the mutually facing ends of the sections 6, 7 with lateral overlap, like this best Fig. 13 is apparent.

In the case of the described end parts 2, 2 ', it is essential that the first and second sections 6, 7 merge into one another in a telescoping or mutually guided manner and / or are elastically coupled to one another, so that the width of the U-shaped or crescent-shaped end part 2, 2' starts from the central vertex or starting from the central portion 12 is variable. It is advantageous if between the first and second section 6, 7, a guide device 11 is formed, which is a relative displacement between the first and second section 6, 7 in a direction parallel to the sliding or Aufstandsebene and transverse to the longitudinal direction of a ski or snowboard direction allows. The guide device 11 between the first and second sections 6, 7 can be designed in the manner of a tongue and groove connection or in the manner of a tongue and groove connection. This guide device 11 is further designed such that relative adjustments between the first and second sections 6, 7 of the end part 2, 2 'in the direction perpendicular to the underside or to the sliding surface of a ski or snowboard are prevented. In particular, the end part 2, 2 'prevents or reduces relative movements or displacements between the sliding board tongues 23, 24 and 23' 24 'in a direction perpendicular to the lower or upper side of the sliding board body 3, as shown in particular in the illustrations according to FIGS Fig. 1 to 2a can be seen.

The end portion 2, 2 'thus causes a load or force-transmitting coupling between the two sliding board tongues 23, 24 and 23', 24 ', whereby the stability or the bending behavior of the respective end portion of the sliding board body 3 is positively influenced. With the specified end parts 2, 2 'so the performance of a geometry or waist variable sliding board body 3 can be further increased. In particular, with the specified end parts 2, 2 'an improved cornering behavior or a more precise controllability of the sliding board body 3, in particular of the ski or snowboard, is achieved.

It is advantageous if at least the front end part 2, in particular its first and second section 6, 7 are designed in cross-section substantially U- or L-shaped. As a result, a good hold of the end part 2 is achieved in the respective end portion of the sliding board body 3. In addition, a disguise or concealment of the front end face or the rear end face of the sliding board body 3 is achieved by this shaping. In particular, the end part 2 can thereby be inserted or pushed over the front end of the sliding board body 3, whereby it can be mounted as stable as possible and particularly resistant to detachment during the production of the sliding board body 3 or the ski 1 or snowboard.

In the Fig. 14, 15th is another embodiment of a front end portion 2 illustrated, wherein such an end portion can of course also be used at the rear end portion of a sliding board body 3. In the embodiment according to Fig. 14 are the first and second sections 6, 7 in the facing zones 8, 9 one-piece coupled. That is to say, the sections 6, 7 merge into one another in the middle section 12 of the end part 2. In particular, the two lateral sections 6, 7 are connected to one another by means of an elastic bridging element 25 or via an elastic middle section 12. The central portion 12 may be embodied in the manner of a film hinge arrangement, wherein an articulated or film hinge-like connection between the sections 6, 7 can be constructed by a material selection and / or shaping known per se for the middle section 12.

The elastically deformable central portion 12 is preferably designed such that it opposes the occurring during driving and / or according to individual presets occurring width variations of the sliding board body 3 as low as possible resistance.

The elastically deformable central portion 12 is thus in the embodiment according to Fig. 14 formed in the adjacent zones 8, 9 of the first and second sections 6, 7. In the zones 33, 34 of the first and second sections 6, 7 facing away from these zones 8, 9, the first and second sections 6, 7 of the end section 2 are each hinged to the opposite side edges 37, 38 of a ski or snowboard, in particular with the sliding board tongues 23, 24 connectable. In the embodiment according to Fig. 14 is the articulated connection between the outer and distal zones 33, 34 and the respective sliding board tongues 23, 24 formed by bolt-like fastening means 39, 40, in particular by screws or rivets. Via these fastening means 39, 40, the outer zones 33, 34 of the first and second sections 6, 7 are each connected in an articulated manner to the sliding board tongues 23, 24. This results in a triangular arrangement, wherein the corner points are defined at the base of this triangular arrangement by the articulated connection via the fastening means 39, 40. The joint at the top of this triangle arrangement, however, is implemented by the elastically deformable central portion 12. The fixing means 39, 40 for the first and second sections 6, 7 positioned at the outer end sections thus also form pivot bearings 31, 32 between the outer zones 33, 34 of the sections 6, 7 and the respective associated sliding board tongues 23, 24.

By a distance or an exemption 41 between the front end of the sliding board body 3 and the front-side inner wall and the front boundary wall of the end portion 2, a relative adjustability between the end portion 2 and the end portion of the sliding board body 3 is ensured. This freedom 41 or this range of motion is needed especially when the width of the sliding board body 3 is increased or decreased. In particular, in lateral evasive movements of the sliding board tongues 23, 24 relative to the longitudinal center axis of the sliding board body 3 related to the direction of travel of Gleitbrettkörpers 3 forward displacement or return displacement of the apex or central portion 12 causes, as was symbolized by the double arrows.

In the embodiment according to Fig. 15 are the adjacent zones 8, 9 of the sections 6, 7 instead of an elastically stretchable and recoverable bridging element 25 by means of a joint 42 connected to each other. For this purpose, overlap the first and second sections 6, 7, wherein these two sections 6, 7 within its overlapping zone yield the articulated central portion 12. Also in this embodiment, a triangular arrangement is provided whose base distance between the outer zones 33, 34 is variable in length and whose legs are formed by the sections 6, 7. A height perpendicular to the base of this triangular arrangement is variable depending on the width changes of the sliding board body 3. Via the joint 42, a relatively movable displacement of the central portion 12 and the zones 8, 9 in the longitudinal direction of the sliding board body 3 is made possible. Alternatively or in combination with rotary bearings 31, 32 between the outer zones 33, 34 and the sliding board tongues 23, 24, it is also possible to form in or on the lateral sections 6, 7 at least one elastic deformation zone 35, 36, as shown in FIG Fig. 15 has been illustrated schematically.
