The invention relates to a ski or a snowboard, a method for producing a prefabricated semi-finished product for the production of such a ski or snowboard, a correspondingly constructed semi-finished product, and a method for producing the ski or snowboard according to the invention using the prefabricated semi-finished product, as shown in the Claims 1,11,18 and 19 is given.
AT 407 491 B, which is assigned to the Applicant, describes a method for producing a ski and a correspondingly constructed ski. In this case, the so-called shell or cap construction is applied by preparing a shell having a U-shaped cross section comprising an outer cover layer together with an impregnated reinforcing layer. After making this U-shaped shell a Schikem is inserted between the legs and introduced plastic in the remaining spaces. Finally, a ski body results, in which the outer cover layer forms the upper side and the lateral longitudinal walls. The used, preparatory manufactured ski cores have apart from structural depressions or elevations on the upper and lower flat side either a substantially rectangular cross-section or a substantially trapezoidal cross-section, the trapezoidal shape of the ski and the substantially trapezoidal cross-sectional contour of the ski body are aligned identically are implemented with identical orientation. Accordingly, the longitudinal side walls of the ski body and the longitudinal side walls of the ski body are either parallel to each other with respect to the cross section of the ski body or they are angled relative to each other. The cross-sectional width of the ski viijüngt N2011 / 12100 Λ Λ ·· ·· • * · • * · · starting from the tread surface in the direction of the upper deck surface of the ski body. This structure and this production method have proven useful for many applications, but the achievable cost-effectiveness and process stability is only partially satisfactory.
The AT 11 519 U1, which also goes back to the applicant, describes a further method for producing a ski or snowboard, in which the Längsseitenfiächen are at least partially formed by structurally independent side cheek elements. In this case, a semi-finished product is prepared preparatory, which is formed from the top layer, the top flange and at least one side cheek element of the later ski or snowboard. It is also provided, in addition to cement the core element to this prefabricated semi-finished adhesive. Also in this production process, a core element is used which has a cross-sectionally substantially rectangular or trapezoidal cross-sectional contour and wherein a substantially trapezoidal cross-sectional contour of the ski or snowboard is aligned quasi congruent or identical orientation to the substantially rectangular or trapezoidal cross-sectional contour of the core element , Also, the process reliability in the course of completion of the semifinished product to a gliding board body, that is, during the adhesive connection of the semi-finished product with the remaining components of the manufactured ski or snowboard, only partially satisfactory.
The present invention has for its object to provide a ski or snowboard or to provide a method for its production, which allows the most cost-effective and fail-safe production process to create high quality Gleitbrettkörper.
The object of the invention is achieved on the one hand by the measures according to claim 1. Such a ski or such a snowboard comprises a multilayer gliding board body, which meets high standards in terms of quality and economical production possible. The core element, which differs with respect to the cross-section of the multilayered board body N2011 / 12100 -3-
* * • t I • * 4 • · · · · · I · t · · «* ♦
going continuously or discontinuously widened from the tread covering in the direction of the upper cover layer, offers, inter alia, production-specific advantages which result in a relatively high and also stably achievable product quality. In particular, this ensures the most reliable or process-reliable bonding of the core element to the surrounding elements or layers. As a result, reject rates or quality-impaired products can be minimized. In particular, a reliable filling of those cavities is achieved with the intended filling and adhesive, especially in connection with prefabricated semi-finished products, which are of importance for the quality and stability of the multilayer Gleitbrettkörpers. In addition, the manufacturing process of a corresponding trained Gleitbrettköpers run time-optimized and relatively fail-safe.
By the measures according to claim 2, a high degree of filling or a high filling reliability is achieved in relation to the spaces between the longitudinal side walls of the sliding board body and each next-lying leg surfaces of the core element. In particular, thereby filling as far as possible full filling of these spaces is ensured even at relatively low injection pressures for the filling and adhesive over the corresponding spaces. In particular, a kind of integral nozzle function is thereby constructed by the respective components of the sliding board body, whereby the introduction of the filling and adhesive agent is ensured even in relatively narrow or relatively far from the injection site positions. The corresponding structural measures thus achieve the construction of high-quality gliding board body, in which the risk of undesirable decreases in strength or delamination is minimized.
Also advantageous are the measures according to claim 3, since in addition to a reliable filling or in addition to a high degree of filling of the wedge-shaped interstice gap with filling and adhesive and a high-strength, adhesive connection of the at least one Eist-shaped side cheek element is ensured on the sliding board body. In particular, this increases the achievable robustness or, as a result, the likelihood of delamination N2011 / 12100 -4-: ·· ··· · ♦ *
Or a detachment of the at least one side cheek element is minimized. Thus, this high-quality sliding board body are achieved, which are technically relatively economical to build up.
Also of advantage are the measures according to claim 4, since cavities or air pockets in the provided for filling with filling and adhesive portions of the sliding board body are thereby retarded. In particular, a full as possible filling of the hollow or spaces is thereby achieved even if the filling and adhesive is relatively viscous in its flowable Ur- or processing state or is relatively viscous. In particular, tapered niches in which cavities or air pockets could arise without fillers and adhesives are greatly reduced or avoided.
But even by the measures according to claim 5, a high degree of filling of the cross-section substantially wedge-shaped intermediate space is achieved. This increases the reliability or strength of the corresponding adhesive connection. Under certain circumstances, the time required for complete filling of the corresponding, wedge-shaped in cross-section cavities can be reduced. In particular, this achieves a type of nozzle effect which ensures reliable filling even of relatively narrow gaps or cavities between the at least one strip-shaped side wall element and the core element.
Of particular advantage are the measures according to claim 6, since an improved, cohesive or adhesive connection between the at least one strip-shaped side cheek element and the Kemele-element is created. In particular, this significantly increases the thresholds for delamination or detachment of elements, which results in robust and high-quality skis or snowboards. In addition, this process reliability is increased in the course of producing such a ski or snowboard. In particular, this surface treatment or roughening, on the one hand, produces a material bond and, on the other hand, a certain degree of N2011 / 12100 · * - 5 -ί * · w ^ if • * · * * * * * • · · · · · · · · * • ••••••••••••••••••••••••••••••••••••••••••••••••••••••••
Extent also created a force or positive connection between the filling and adhesive and the corresponding surfaces of the at least one side cheek element and the core element.
Also advantageous are the measures according to claim 7, since a simple or uncomplicated production of Gleitbrettkörpers is achieved. In addition, this improves the transmission of force relative to an edge element of the sliding board body. In addition, this ensures a wedge-shaped in cross-section extending gap, which favors the fullest possible filling with filling and adhesive.
The measures according to claim 8, a sliding board body is created, the individual components are combined into a high-strength composite body, after the filling and adhesive ensures a full or large as possible, mutual bonding of said elements or components.
Also by the measures according to claim 9 a uniform and cavity-filling distribution of the originally flowable filling and adhesive is supported. In particular, the strength-relevant bottom flange is embedded as completely as possible in the filling and adhesive or is ensured even with one-sided introduction of flowable in the original state filler and adhesive as complete as possible integration of the metallic strip in the final curing filler and adhesive. The strength of the ski or snowboard and its product quality is thus further increased.
Another advantage is the embodiment according to claim 10, as a ski or snowboard is thereby created, which withstands high stresses, in particular high loads, without being subject to the risk of delamination between the individual layers or components. In addition, the corresponding composite body can thereby be constructed cost-efficiently, in particular quickly and without costly production-consuming measures.
The object of the invention is also achieved by a method for producing a prefabricated semi-finished product according to claim 11. By the given N2011 / 12100 -6-: * ·· φφ ··· φ • · »· • · • m ♦»
Assignment or alignment of the core element relative to the top flange or the cover layer, a semi-finished product is created, which supports reliable and process-reliable production in the course of the later Komplettiemngs- or joining process to create the component completed or supplemented Gleitbrettkörpers. In particular, a semi-finished product is produced by the corresponding method, which creates a good starting point for a high-strength, adhesive connection with the remaining, required for the sliding board body components in the course of the later manufacturing or completion process.
Also advantageous are the measures according to claim 12, as this a Gleitbrettkörper can be created, which has at least one structurally independent, strip-shaped side cheek element for limiting at least one longitudinal side wall, the corresponding method measures a reliable connection or a high-strength, material connection with the ensure adjacent components of the semifinished product or the later sliding board body, in particular, thereby the quality of the semi-finished product or a sliding board body ultimately constructed so be increased.
By the provisions according to claim 13 as complete or voilflächige filling the corresponding cavities or spaces is also achieved when a relatively viscous filling and adhesive is used or when the corresponding injection pressures for the filling and adhesive are relatively low , In addition, this ensures that the at least one strip-shaped side cheek element occupies the planned orientation or orientation relative to the tread surface or the other outline contour of the sliding board body ultimately constructed with this semi-finished product with increased reliability.
Also useful are the measures according to claim 14, as a high-strength, adhesive bond between the corresponding roughened surfaces and the thus in contact with filling and adhesive is achieved. In particular, this means, in particular, that the corresponding side walls N2011 / 12100 ··· *
% · I «· ♦ mente particularly reliable and highly stable connected to the final built-sliding board body, which is almost impossible even under increased loads or deflections of Gleitbrettkörpers the probability of detachment or delamination.
A particularly efficient and thorough measure for roughening the corresponding surface sections is specified in claim 15. In addition, it is also relatively difficult to access, in particular substantially cross-sectionally substantially wedge-shaped or V-shaped intermediate spaces, and to be treated or roughened as planned. Moreover, such measures are time efficient and thorough.
By the measures according to claim 16, a tapered space or receiving channel for the filling and adhesive is created, whereby the degree of filling or the Auffüllungszuvertrigkett is increased.
Of advantage are also the measures according to claim 17, since deposits or jamming of particles, which are introduced in the course of a grinding or sandblasting process in the wedge-shaped gap between side cheek element and core element, fail again to a large extent automatically from the intermediate space or can be easily removed. In particular, unwanted accumulations of abrasive particles or of particles which are detached from the treated surfaces are thereby avoided or reduced in the tip region of the wedge-shaped intermediate space. The quality of the subsequent bonding can be increased thereby. In addition, it is achieved that corresponding molds for producing the semi-finished product have no sharp edges or no sharp edges, whereby the service life of the corresponding molds is increased. In particular, blunt edge or area transitions of a molding tool are subject to comparatively lower signs of wear than surface areas tapered to an acute angle. But also the improved particle or sand failure from the wedge-shaped in cross-section gap favors the quality and production stability of a sliding board body to be built. N2011 / 12100 8-: 8-: «· m ·« »··
Claim 18 identifies a semi-finished product, which forms an improved starting point for the completion of a sliding board body in the form of a ski or snowboard. The technical advantages and effects that can be achieved therewith can be found in the preceding and the following parts of the description.
The object of the invention is also achieved by a method according to claim 19. As a result, a sliding board body is created, which on the one hand meets high quality requirements and on the other hand can be produced relatively inexpensively or economically. In particular, a process-reliable or error-free production of corresponding sliding board body is achieved despite a structurally relatively complex appearing construction.
The measures according to claim 20 offer the advantage of a simple yet high-strength cohesive connection of the prefabricated semi-finished product with the other components of the sliding board body to be produced. A particular advantage is that the filler and adhesive or the joining process no additional heating power or heat energy is supplied, whereby the cost efficiency and efficiency in the course of the production of corresponding sliding board body is significantly increased.
Above all, by the measures according to claim 21, an energy-saving manufacturing process is achieved, which achieves decisive ecological and economic benefits.
By the measures according to claim 22, on the one hand, the process cycle can be kept as short as possible, after no warm-up or temperature stabilization times must be maintained. On the other hand, this creates a particularly cost-effective and ecologically improved manufacturing process.
Furthermore, the measures according to claim 23 are advantageous since, after a relatively short reaction or hardening time, the adhesively composite composite body or the gliding board body to be produced from the molds can be produced from the molds ··· __ • ♦ · · fr * «; It is possible to remove the mold from the mold so that relatively short production cycles or joining cycles are achieved. In particular, a high cycle rate with respect to the loading of the pressing device or of the molding tools with sliding board bodies to be produced can thereby be achieved. The economy of the manufacturing process and the Gleitbrettkörper produced thereby is thus improved.
Finally, the measures according to claim 24 are of particular advantage, as this initially little resilient composite body gradually get their final stability or final strength by these stored only at room temperature or temporarily stored easily. The stress and tension freedom of the composite body thereby guarantees plangemäße, high quality composite body or Gleitbrettkörper, which can be easily fed to the respective Nachbearbeitungsprozessen after waiting for the curing time or after reaching a sufficient hardening of the filling and adhesive. The economy, efficiency and quality of corresponding sliding board body is thereby further increased.

An improved embodiment of a ski 1 is illustrated by way of example in FIGS. Such a ski 1 is, as known per se, to use in pairs, wherein a binding device 2 is provided for on-demand connection and decoupling with respect to the foot or sports shoe of a user. Analogous to a Ski 1, it is also possible to provide the following measures in a so-called snowboard, such a snowboard is used individually by a user and both legs of the user can be supported on binding devices on the snowboard as needed and released therefrom.

A corresponding ski 1 or a so-called snowboard comprises a multilayer gliding board body 3, which is provided for gliding on snow, ice or other surfaces. This multilayer sliding board body 3 is thus to be understood as a sandwich element or as a composite body 4, which is formed from a plurality of adhesively interconnected elements.
Such a multilayer gliding board body 3 consists of at least one strength-relevant top flange 5, at least one strength-relevant bottom chord 6, at least one intermediate board-like core element 7, at least one top layer 8 of the gliding board body 3 forming top layer d and at least one bottom side 10 In the case of the embodiment of a skis 1 or snowboard, the lateral longitudinal edges of the tread covering 11 are typically limited by edge elements 12, 13 for improved guidance of the sliding board body 3 on hard or icy ground. These edge elements 12,13 usually consist of metallic materials and are colloquially referred to as steel edges.
The at least one one-piece, possibly composed of several parts tread 11 should aulweisen the highest possible lubricity and abrasion resistance to the respective substrate, such as snow, ice or sand. The cover layer 9 primarily has a protective or decorative function for the gliding board body 3. The cover layer 9 is typically made transparent or translucent and may be provided on the back with a decoration, for example with a sublimation or thermal color printing. Alternatively or in combination with this, a separate decorative layer or decorative carrier layer can also be provided on the rear side remote from the upper side 8.
The upper flange 5 and the lower flange 6 are primarily strength or stiffness-relevant layers or elements in the sliding board body 3 and primarily determine its bending behavior or its load-bearing capacity and breaking strength. The top chord 5 and / or the bottom chord 6 need not be replaced by separate layers or N2011 / 12100 «* ·« -12- • *
Elements may be executed, but may also be defined by adhesives or fillers in the interior of the sliding board body 3. According to the illustrated embodiment, the strength-relevant top flange 5 is formed by a metallic layer, in particular of a light metal. Similarly, the lower chord 6 is formed of a strip-shaped metallic member having a thickness of typically less than 1 mm. Alternatively or in combination, the upper belt 5 and / or the lower belt 6 may also be formed by so-called prepreg elements, which are typically formed by resin-impregnated fabrics, in particular by glass fiber fabrics. By way of example, the upper belt 5 extends over the entire, effective width of the sliding board body 3 so that its longitudinal side edges are visible or accessible with respect to longitudinal side surfaces 14, 15 of the sliding board body 3.
As can best be seen from a combination of FIGS. 1, 2, the gliding board body 3 has a cross-sectionally substantially trapezoidal cross-section, at least in the assembly area of the binding unit 2, the underside 10 formed by the running surface covering 11 forming the comparatively longer base side of this trapezoidal contour in that the upper side 8 defines the relatively short base side and the longitudinal side surfaces 14, 15 represent the laterally inclined legs of the trapezoidal cross-sectional contour of the sliding board body 3.
The board-shaped or strip-shaped core element 7 arranged between the strength-relevant top flange 5 and the strength-relevant bottom flange 6 has a substantially trapezoidal cross-section, at least in partial sections of its longitudinal extent. This trapezoidal cross section is provided at least within the mounting area for a binding device 2. Usually, the core element 7 has a substantially trapezoidal cross-section within 30% to 90% of its longitudinal extent. Such a core element 7 usually has its greatest thickness or thickness in the central longitudinal section and increasingly tapers in the direction of the distal end sections. Especially in the opposite end portions, the core element 7 may also have a rectangular cross-section. It is useful if the N2011 / 12100 -13- * ·
• * · Μ ·
Core element 7 aulweist within its entire longitudinal extent an approximately trapezoidal cross-section. Typically, the length of the core element 7 is made shorter than the nominal length of the final sliding board body 3, wherein the length of the core element 7 about 10 cm to 30 cm, preferably about 20 cm, may be shorter than the nominal length of the sliding board body third
The strip-shaped or board-like core element 7 is essentially limited by a first or upper flat side 16, by a second or lower flat side 17 and by lateral leg surfaces 18, 19. The first and second flat sides 16, 17 are aligned substantially parallel to one another with respect to the cross section through the core element 7. At least one of the leg surfaces 18, 19 extends inclined to the flat sides 16, 17, so that the essentially trapezoidal cross section of the core element 7 is created. There is then also a trapezoidal cross section, when a leg surface 18 or 19 is aligned at right angles to the flat sides 16,17 and the opposite leg surface 19 or 18 is aligned at an acute or obtuse angle to the flat sides 16, 17.
The substantially trapezoidal cross-sectional contour of the core element 7 thus comprises a first base side 20 with a first length 21 and a substantially parallel, second base side 22 with a second, comparatively shorter length 23. The flat sides 16,17 can be flat or planar his or her milled or surveys aulweisen, in order to achieve an intense connection with fillers or adhesives. Nevertheless, at least the majority or a central, virtual plane of the boundary or flat sides 16, 17 of the core element 7 runs essentially parallel to one another, as is illustrated by way of example in FIG. 2. At least one of the lateral leg surfaces 18,19 of the core element 7 extends inclined at least within a portion of the longitudinal extent of the core element 7, in particular obtuse or acute angled to the opposite Fiachseiten 16, 17 or to the corresponding base pages 20, 22. N2011 / 12100 -14- -14- •••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••••
As can be seen by way of example from FIG. 2, the first flat side 16 of the core element 7 with the first base side 20, which is comparatively longer in cross section, is assigned to the upper flange 5 which is relevant to strength. The second flat side 17 of the core element 7, which forms the comparatively shorter, second base side 22 in cross-section, is assigned to the strength-relevant lower flange 6 in the direction of lying. This means that the core element 7, which has a trapezoidal cross-section at least within sections of its longitudinal extension, is integrated in the sliding board body 3 quasi "upside down". In particular, the core element 7, which has a substantially trapezoidal cross-sectional contour at least in the central longitudinal section, is installed or implemented in the gliding board body 3, as best shown in the exemplary illustration according to FIG. 2, in the same way as the outer, substantially trapezoidal cross-sectional contour of the sliding board body 3 can be found.
Preferably, the core element 7 is formed from a wood material. In this case, several wooden strips or wooden slats can be glued to a one-piece core element 7. The inclined, lateral leg surfaces 18, 19 and possibly existing surface structuring in the form of elevations or depressions on the upper and / or lower flat side 16, 17 are preferably produced by milling processes. The core element 7 formed of wood preferably represents a prefabricated component, which is assembled in the course of the manufacture of the sliding board body 3 with the remaining components to the one-piece composite body 4. As an alternative to a so-called wood core, it is also possible to provide a core element 7 made of plastic. Such a core element 7 can be designed as a hollow profile to have the lowest possible mass. However, a core element 7 formed from plastic can also be formed by a foam core, for example made of PU foam. Such core elements 7, which are alternative to wooden materials, also have a substantially trapezoidal cross-section at least within the central longitudinal section, the core element 7 being integrated into the gliding board body 3 inversely to the outer, essentially trapezoidal cross-sectional contour of the gliding board body 3 in accordance with the preceding illustrations.

This opposite alignment of the trapezoidal shape of the core element 7 relative to the trapezoidal shape of the sliding board body 3 results in production engineering and structural advantages, as stated in the introduction.
As can further be seen best from FIG. 2, at least one intermediate space 24, 25 is interposed, inter alia, by the cross-sectional width of the core element 7 which increases in the upward direction, in particular by a type of V-orientation of the essentially trapezoidal core element 7 at least one longitudinal side wall 26, 27 of the sliding board body 3 and the leg surface 18, 19 of the core element 7 closest to this longitudinal side wall 26, 27 are formed. This gap 24, 25 remains in the ready state of the sliding board body 3 is not empty, but at least for the most part filled with a filling and adhesive 28. It is essential that this gap 24, 25 between a side Schenketfläche 18,19 of Kemelementes 7 and the next associated longitudinal side wall 26,27 of the sliding board body 3, starting from the top flange 5 and starting from the top layer 9 in the direction of the lower flange 6 and widens in the direction of the tread surface 11 with respect to the cross section of the sliding board body 3. This broadening can, as shown schematically, be provided continuously or else be discontinuous, in particular in a stepwise or stepwise manner. Accordingly, a cross-sectionally substantially wedge-shaped intermediate space 24, 25 is provided, which widens starting from the upper side 8 in the direction of the underside 10 of the sliding board body 3 and is at least largely filled with filling and adhesive 28. Among other things, this filling and adhesive agent 28 produces an adhesive bond between the said components in order to ensure the one-piece composite body 4.
The opposite longitudinal side walls 26, 27 of the Gieitbrettkörpers 3 can be formed by a cross-sectionally substantially C-shaped cover layer 9, wherein the lateral legs of the cross-section substantially Ö-shaped cover layer 9 at least form part sections of the longitudinal side walls 26,27. Such a construction is commonly referred to as a "cap construction". As exemplified in FIG. 2, the longitudinal side walls N2011 / 12100 -16- * Φ ♦ ··· »Φ # ·· But also be formed by structurally independently formed, strip-shaped side cheeks elements 29,30 »« ··· · .phi. · .Phi..sub.phi .phi..sub.php. These side cheek elements 29, 30 form the lateral end of the gliding board body 3, in particular its longitudinal side walls 26, 27. Moreover, it is possible to form the longitudinal side walls 26, 27 by a combination of side cheek elements 29, 30 and a cover layer 9 which is substantially U- or C-shaped in cross-section. In this case, portions of the longitudinal side walls 26, 27 are formed by side cheek elements 29,30 and by the Schenkelabschnrtte a cross-sectionally substantially U-shaped cover layer 9. However, it is also expedient to use the embodiment illustrated in FIG. 2, in which structurally independent side cheek elements 29, 30 predominantly form the opposite longitudinal side walls 26, 27 of the gliding board body 3.
According to an expedient embodiment, as illustrated in FIGS. 3-5, it is provided to form at least one longitudinal side wall 26, 27 by at least two side cheek elements 29, 29 'or 30, 30' arranged one above the other. The corresponding side cheek elements 29,29 'and 30, 30' are designed strip or strip-like and preferably formed from plastic. The corresponding superimposed side cheek elements 29,29 'and 30, 30' can have different height and length dimensions. While the lower side cheek elements 29,30 may extend over most of the longitudinal extent of the gliding board body 3, it is desirable that the upper side cheek element 29 ', 30' extend only a fraction of the length of the gliding board body 3, as best shown in FIG Figure 1 shows. According to an advantageous embodiment, the upper side cheek element 29 ', 30' preferably extends approximately within the mounting region of the binding device 2. Conveniently, the upper side cheek element 29 ', 30', which rests on the lower side cheek element 29, 30 touch-transmitting, made of an elastomeric plastic formed, whereas the lower side cheek element 29, 30 is preferably formed of a hard plastic. The height extent of the at least one side cheek element 29, 29 'or 30, 30' in this case corresponds approximately to the vertical distance between...

These opposite each other in relation to the width of the sliding board body 3 intermediate spaces 24, 25 are thus filled with filling and adhesive 28, wherein they are starting from the upper flange 5 of Glert board body 3 in the direction of the lower flange 6 with respect to the cross section of the sliding board body 3 widen. The cross-section of the intermediate spaces 24, 25 or of the wedge of originally flowable filling and adhesive 28 embedded therein, and finally cured, is thus substantially A-shaped in cross-section.
According to the illustrated embodiment of FIG. 2, it is expedient if the inner surface 31, 32 of the at least one strip-shaped side cheek element 29, 29 'or 30, 30' is aligned essentially at right angles to the running surface of the tread surface 11. The side cheek element 29, 30 is supported on a respective edge element 12,13 load-transmitting.

It is expedient if the inner surface 31, 32 of the longitudinal side wall 25, 26 and / or the inner surface 31, 32 of the strip-shaped side wall element 29, N2011 / 12100 -18- # * ♦ * * «« * • «« * • · «· ···················································································································································································································································· about 20 °.
In order to achieve an improved cohesive or adhesive connection with the filling and adhesive 28, it is expedient, the inner surfaces 31, 32 of the longitudinal side walls 26, 27 and the inner surfaces 31, 32 of the strip-shaped side cheek elements 29,29 ', 30, 30' and roughen the next leg surfaces 18, 19 of the core element 7 by a Oberflächenbearbettung, in particular by an abrasive surface treatment, before said surfaces 31, 32; 18,19 come into contact with the filling and adhesive 28. The corresponding roughening of these surfaces is expediently carried out by a sandblasting method, as was illustrated schematically in FIG. 5.
The filler and adhesive 28, which is preferably made of polyurethane, connects the core element 7, the at least one strip-shaped side cheek element 29, 29 ', 30, 30', the at least one lower flange 6 and the at least one tread covering 11 to the one-piece composite body 4. In addition, ailfällig formed edge elements 12,13 are adhesively bonded by means of this filling and adhesive 28 to the one-piece composite body 4.
According to an expedient embodiment, the at least one lower flange 6 is formed by a metallic band 35. This band 35 preferably comprises a plurality of distributed apertures 36, as shown schematically in FIGS. 2, 4. These apertures 36 represent connecting channels 37 between the layers 38, 39 located above and below the metallic strip 35 of filling and adhesive 28. These connecting channels 37 are at least partially filled with the filling and adhesive 28, so that they are above and below of the band 35 lying layers 38, 39 of filler and adhesive 28 integrally connect together. The breakthroughs 36 represent during the manufacturing process transition channels, so that an intensive embedding of the quasi-perforated belt 35 is ensured in the filling and adhesive 28.

FIG. 3 schematically illustrates a central process measure during the production of a prefabricated semi-finished product 40. Such a semifinished product 40 prepared in preparation represents a subcomponent for the production of a ski 1 or snowboard illustrated in FIG. 1.
This semifinished product 40 is embodied as a multipart, one-piece subcomponent, which comprises at least the cover layer 9, at least part of the strength-relevant top flange 5 and at least one core element 7 of a later gliding board body 3 that is materially or adhesively bonded to the underside of the strength-relevant top flange 5. The upper belt 5 may comprise, for example, a so-called prepreg which, under the action of temperature and pressure, ensures an adhesive connection of the upper, first flat side 16 of the core element 7 to the upper belt 5 or to the cover layer 9.
The corresponding core element 7 is formed strip-like or board-like and extends in about more than 70% to 95%, preferably about in about 85% of the nominal length of the sliding board body to be produced. The core element 7, which according to the game is formed by a plurality of wooden lamellae 41 which are glued together to form a one-piece body, has an outline contour that is essentially trapezoidal in cross-section. Considered as a body, the core element 7 thus has a first and second flat side 16,17, which viewed in cross section substantially parallel to each other and bounded by two lateral leg surfaces 18,19, wherein at least one leg surface 18 or 19 inclined, that is from is aligned at a right angle deviating from the flat sides 16,17. In those partial sections of the longitudinal extension of the core element 7, in which there is a trapezoidal cross-section, the cross-sectional contour thus has a first base side 20 with a first width or length 21 and a substantially parallel, second base side 22 with a second, comparatively shorter width or length 23 on.
It is essential that in the course of the production of the semi-finished product 40, as exemplified in Fig. 3, the trapezoidal in cross-section core element 7 with the underside of the strength-relevant top flange 5 and the N2011 / 12100 -20- • · * * · · · · · · · · · · Ft ft Μ *

Cover layer 5 is connected in such a material-locking or adhesive manner that the first flat side 16 of the core element 7 is associated with the cross-sectionally comparatively longer base side 20 of the festigkeitsrefevanten upper flange 5 next, whereby the side facing away from the strength-relevant top flange 5 underside of the core element 7 through the second flat side 17th the core element 7 is formed with the cross-sectionally comparatively shorter base side 22. Accordingly, the core element 7 is implemented in the semifinished product 40 such that its cross-sectional width tapers from the cover layer 9 in the direction of the later running surface covering 11 of the sliding board body 3 to be produced, in particular continuously or discontinuously narrowed, as is the case with a synopsis of FIGS. 2, 3 can be seen.
According to an expedient measure, provision is made for the semifinished product 40 prepared in advance to further comprise at least one strip-shaped side cheek element 29, 29 ', 30, 30', which prior to joining or before supplementing the semi-finished product 40 with the further or completing components of the final one Gliding board body 3 is an additional component of the prefabricated semi-finished product 40. This at least one strip-shaped side cheek element 29, 29 ', 30, 30', which forms at least one section of at least one longitudinal side wall 26, 27 of the final gliding board body 3, is provided with at least one longitudinal side edge 42, 43 of the cover layer 9 or with the bonded to the underside of the cover layer 9 upper belt 5 glued, as can be seen in particular the schematic representation of FIG. 3 Such a bonding process can be implemented for example in the course of a hot pressing or cold gluing process.
In the course of the joining or the adhesive bonding of at least one leis tenförmigen side cheek element 29,29 ', 30,30' to the underside of the upper flange 5 and the cover layer 9 is formed with respect to the core element 7 in cross-section substantially wedge-shaped gap 24,25, which is filled in the course of the later completion of the semi-finished product 40 to a sliding board body 3 at least for the most part with filling and adhesive 28, as is known from N2011 / 12100 -21 - •·· *
* A synopsis of Fig. 3.4 can be seen. This wedge-shaped intermediate space 24, 25 which is finally filled with filling and adhesive 28 becomes essentially in relation to the width direction of the sliding board body 3 by the inner surface 31, 32 of the at least one strip-shaped side cheek element 29, 29 ', 30, 30 facing the core element 7 'and limited by the next adjacent, inclined leg surface 18,19 of the core member 7, as best seen in FIG. 4 can be seen. Accordingly, a cross-sectional width 33, 44 of the cross-sectionally substantially wedge-shaped intermediate space 24, 25 is dimensioned progressively larger starting from an end section 5 closest to the upper flange 5 in the direction of an end section closest to the lower flange 6. This is achieved primarily by the inclined leg surfaces 18,19 of the Kemele-element 7, but can also be reinforced by correspondingly inclined inner surfaces 31, 32 of the longitudinal side walls 26,27.
As has been illustrated schematically, in particular, in FIGS. 2, 4, it is expedient to have the smallest cross-sectional width 33 of the intermediate wedge-shaped intermediate space 24, 25 in its end section closest to the top flange 5 with more than 0.5 mm, preferably between 0 , 5 mm and 5 mm, preferably set at about 1.5 mm.
As was schematically illustrated in FIG. 5, it is expedient, at least the lateral boundary surfaces of the wedge-shaped intermediate space 24, 25 provided for filling with adhesive 28, in particular the inner surfaces 31, 32 of the at least one strip-shaped side cheek element 29, 29 ', 30, 30 'and the respectively next adjacent leg surfaces 18,19 of the core element 7 roughen on their surfaces before these spaces 24, 25 are filled or filled with the flowable in the original state filling and adhesive 28. As schematically illustrated in FIG. 5, it is particularly expedient to carry out this roughening of the corresponding surfaces which are to come into contact with the filling and adhesive 28 by means of an abrasive treatment process. In particular, it is expedient to use a sand blasting method for this purpose. As is known per se, abrasive particles, for example grains of sand or other, abrasive particles, are thereby dispersed. N2011 / 12100 -22- «· 4 ··· ··· t · · · · · · · I · ·» » ···································································································································································· As a result, an improved, in particular a high-strength and reliable, adhesive bond between the core element 7 and the in the original state, relatively flowable or low-viscosity fillers and adhesives 28 can be achieved, especially when using a wood core 7 and longitudinal side walls 26, 27 made of plastic.
A prefabricated semi-finished product 40, as illustrated by way of example in FIG. 5, is connected in a subsequent method step with the further components required for the final gliding board body 3, such as the tread covering 11, the strength-relevant lower flange 6 and optionally with edge elements 12, 13 this was illustrated in FIG. 4. In such a joining or manufacturing process for the gliding board body 3, such as a ski 1 or a snowboard, the prefabricated semi-finished product 40 is adhesively joined together with the remaining components according to FIG. 5. The semi-finished product 40 described above, which is manufactured according to the previous explanations or was constructed by means of a pressing device 45 and at least one mold 46, 47 in at least one subsequent or separate pressing cycle with the other completing components of the produced Gleitbrettkörpers 3, such as its tread 11, its strength-relevant lower flange 6 and optionally provided edge elements 12,13 connected. This adhesive compound is preferably carried out by means of a polyurethane-based filling and adhesive agent 28 which reacts sufficiently rapidly or sets at room temperature, in particular also at room temperature. This in the course of the joining process of FIG. 4 relatively liquid filling and adhesive 28 with high fluidity can reach and fill even the smallest gaps sufficiently well or relatively quickly. The wedge shape of the intermediate spaces 24, 25 between the leg surfaces 18, 19 of the core element and the inner surfaces 31, 32 of the longitudinal side walls 26, 27 thereby favors the highest possible degree of filling of these intermediate spaces 24, 25.
Expediently, the joining or pressing cycle illustrated in a highly schematic manner in FIG. 4 for the adhesive bonding of the semi-finished product 40 to the further N2011 / 12100 -23-
Components of the produced Gleitbrettkörpers 3 executed as a cold press cycle. This means that in the course of this adhesive joining process preferably no additional or no external energy is fed into the joining process. The room-temperature chemical reaction of the polyurethane-based filler and adhesive 28, for example by means of Modipur®, alone is sufficient to achieve an adequate bonding or gluing process.
The filler and adhesive 28, which is preferably based on polyurethane, is formed by a flowable in the processing state and low-viscosity and curing under room temperature, two-component mixture of a polyol and an isocyanate. These components are mixed shortly before processing or in the course of processing and introduced using a Ein-injection process (RIM) in the forming molds 46, 47 - Fig. 4 - or pressed between the individual layers or layers of composite body 4 to be produced ,
The in the original state relatively liquid or easily flowable filling and adhesive 28 in the cured state has a density between 1000 to 1200 kg / m3, preferably of about 1100 kg / m3, and a hardness between 60 to 90 Shore D, preferably from in about 70 Shore-D. The particularly efficient or economical curing of the filling and adhesive 28 is achieved inter alia by a filler and adhesive 28 based on polyols and Isocya-naten to be mixed.
This ensures that the produced Giteitbrettkörper 3 or the one-piece composite body 4 already after an initial reaction or hardening time of the filling and adhesive 28 between 1 min and 20 min, preferably between 2 min and 10 min, in particular between 3 min and 5 min can be removed from the pressing device 45 or unfurled from the mold 46,47, without being subject to increased risk of delamination.
According to a further measure, it is provided that the sliding board body 3 or the one-piece composite body 4 to be produced, after removal from the N2011 / 12100 -24- ·· ** v «♦ # ·· · • 4 4 4 4 m 9 44 4 **« The pressing device 45 is stored stress-free and stress-free at about room temperature, and the curing time of the filling and adhesive 28 before further processing of the multilayer sandwich element, in particular before a grinding or cutting processing of interfaces of the sliding board body 3, is awaited. In such a grinding, cutting or machining, for example, it is provided to provide the longitudinal side walls 26, 27 of the composite body 4 with respect to the tread surface 11 trapezoidally inclined or slightly inclined in the direction of the core member 7 longitudinal side surfaces 14, 15, as shown in FIG. 2 in full lines and in Fig. 4 has been illustrated with dashed lines. The inclination of these longitudinal side surfaces 14,15 of the sliding board body 3 with respect to a vertical plane is preferably between 2 ° and 6 °, preferably about 4 °.
