Description

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.

The AT 407 491 B , which is based on 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 Schikern 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. Thus, the longitudinal side walls of the ski body and the longitudinal side walls of the ski body are either parallel to each other or angularly aligned with respect to the cross section of the ski body. The cross-sectional width of the ski tapering, starting from the tread surface toward 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 another method for producing a ski or snowboard, in which the longitudinal side surfaces are at least partially formed by structurally independent side cheek elements. In this case, a semi-finished product is prepared preparatory, which consists of the top layer, the top chord and at least one side cheek element of the later ski or snowboard is formed. It is also envisaged, in addition, to adhere the core element adhesively to this prefabricated semi-finished product. Also in this manufacturing 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 widens continuously or discontinuously in relation to the cross-section of the multilayered Gleitbrettköpers starting from the tread surface toward the upper cover layer, offers, inter alia, production-specific advantages, which results in a relatively high and stable 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 the respective nearest leg surfaces of the core element. In particular, a full as possible filling of these spaces is thereby 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 strip-shaped side cheek element is ensured on the sliding board body. In particular, this increases the achievable robustness or, as a result, minimizes the likelihood of delamination or detachment of the at least one side cheek element. 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. In certain circumstances This can also reduce the time required for complete filling of the corresponding wedge-shaped cavities in cross-section. 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 cheek 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 core 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 creates a material bond and on the other hand to some extent also 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, as a result, the strength-relevant bottom flange is embedded as completely as possible in the filling and adhesive, or even when unilaterally introduced in the original state flowable filling and adhesive ensures the fullest 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. The specified assignment or orientation of the core element relative to the top flange or the cover layer, a semi-finished product is created, which supports reliable and reliable production in the course of the later completion 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 semi-finished or later sliding board body. In particular, this can increase the quality of the semi-finished product or of a sliding board body ultimately constructed therewith.

By the provisions according to claim 13 as complete as possible or full-surface filling of the corresponding hollow 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, it will ensures that the at least one strip-shaped side cheek element occupies the planned alignment or orientation with respect to the tread surface or the other outline contour of the finally built with this semi-finished sliding board body 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, in particular the corresponding side cheek elements are thus connected in a particularly reliable and highly stable manner to the finally built-on gliding board body, whereby the probability of detachment or delamination is almost ruled out even under increased loads or deflections of the gliding board body.

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 provided, whereby the degree of filling and the Auffüllungszurisikoigkeit is increased.

Also advantageous are 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 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.

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 can be removed from the molds 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.

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

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

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

In the Fig. 1 . 2 an improved embodiment of a Schi 1 is exemplified. 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 Schi 1, it is also possible to provide the measures indicated below in a so-called snowboard, wherein such a snowboard is used by a user individually and both legs of the User on binding devices on the snowboard if necessary, held and can be solved.

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 9 and at least one the bottom 10th 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 are usually made of metallic materials and colloquially referred to as steel edges.

The at least one integral, possibly composed of several parts tread 11 should have 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 decor, 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 upper flange 5 and / or the lower flange 6 need not be performed by independent layers or elements, but can 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.

How best from a synopsis of Fig. 1 . 2 it can be seen, the sliding board body 3 at least in the mounting region of the binding unit 2 has a cross-sectionally substantially trapezoidal cross-section, wherein formed by the tread 11 base bottom 10 forms the comparatively longer base side of this trapezoidal contour, the top 8 defines the relatively short base side and the longitudinal side surfaces 14, 15 represent the side, inclined aligned 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 upper flange 5 and the strength-relevant lower 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 middle 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 expedient if the core element 7 has an approximately trapezoidal cross-section within its entire longitudinal extent. 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 substantially trapezoidal cross-section of the core element 7 is formed. 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 be or have milled or surveys 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 substantially parallel to one another, as shown in FIG Fig. 2 is exemplified. 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 angle to the opposite flat sides 16, 17 and to the corresponding base sides 20, 22nd

How out Fig. 2 can be removed by way of example, 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 associated with the strength-relevant lower flange 6 next to it. 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 in the gliding board body 3 counter to the outer, essentially trapezoidal cross-sectional contour of the gliding board body 3 or implemented as best of the example representation according to Fig. 2 can be seen.

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 operations. 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.

How best to look Fig. 2 is apparent, inter alia, by the upwardly increasing cross-sectional width of the core element 7, in particular by a kind of V-orientation of the cross-section substantially trapezoidal core element 7, at least one gap 24, 25 between at least one longitudinal side wall 26, 27 of the sliding board body 3 and to this longitudinal side wall 26, 27 nearest leg surface 18, 19 of the core element 7 is 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 lateral leg surface 18, 19 of the core element 7 and the next longitudinal side wall 26, 27 of the sliding board body 3, starting from the upper belt 5 and starting from the cover layer 9 in the direction of the lower belt 6 and widened 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 opposing longitudinal side walls 26, 27 of the sliding board body 3 can be formed by a substantially C-shaped cover layer 9, wherein the lateral legs of the cross-sectionally substantially C-shaped cover layer 9 at least partial sections of the longitudinal side walls 26, 27 form. Such a construction is commonly referred to as a "cap construction". As in Fig. 2 illustrated by way of example, the longitudinal side walls 26, 27 can also be formed by structurally independent, strip-shaped side cheek elements 29, 30. 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, subsections of the longitudinal side walls 26, 27 are formed by side cheek elements 29, 30 and by the leg sections of a cross-sectionally substantially U-shaped cover layer 9. It is also useful in the Fig. 2 illustrated embodiment in which structurally independent side cheek elements 29, 30 form the opposite longitudinal side walls 26, 27 of the sliding board body 3 in a predominant extent.

According to an expedient embodiment, as described in the Fig. 3-5 is illustrated is provided, at least one longitudinal side wall 26, 27 by at least two superimposed side cheek elements 29, 29 'and 30, 30' to form. 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 for the upper side cheek element 29 ', 30' to extend only a fraction of the length of the gliding board body 3, as best shown Fig. 1 is apparent. 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 load-transmitting, made of an elastomeric plastic formed, whereas the lower side cheek element 29, 30 is preferably formed of a hard plastic. The vertical extent of the at least one side cheek element 29, 29 'or 30, 30' corresponds approximately to the vertical distance between the upper flange 5 and the lower flange 6 and between the upper flange 5 and the lateral edge elements 12, 13 of the sliding board body third

According to an expedient embodiment, as in Fig. 2 Thus, at least one partial section of at least one longitudinal side wall 26, 27 of the sliding board body 3 is formed by at least one strip-shaped side cheek element 29, 29 ', 30, 30' whose inner surface 31, 32 facing the core element 7 has the next leg surface 18, 19 of the core element 7 a at least largely filled with filling and adhesive 28 gap 24, 25 defines. 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 widen from the top flange 5 of the sliding board body 3 in the direction of the lower flange 6 with respect to the cross section of the sliding board body 3 , The cross-section of the intermediate spaces 24, 25 or of the wedge of originally flowable filling and adhesive 28 embedded therein, and finally hardened, is thus substantially A-shaped in cross-section.

According to the illustrated embodiment according to 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 substantially 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 from a load-transmitting.

According to an expedient embodiment, it is provided that the substantially wedge-shaped intermediate space 24, 25, which is filled at least for the most part with the filling and adhesive 28, is made blunt or flattened in its upper end section closest to the upper flange 5, in particular a smallest cross-sectional width 33 of more than 0.5 mm, preferably between 0.5 and 5 mm, preferably about 1.5 mm.

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 cheek element 29, 29 ', 30, 30' with the nearest leg surface 18, 19 of the core element 7, a wedge angle 34 between 5 ° and 30 °, preferably of 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 cheeks 29, 29 ', 30, 30' and roughen the next leg surfaces 18, 19 of the core element 7 by a surface treatment, 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 described in US Pat Fig. 5 has been illustrated schematically.

The filling and bonding agent 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, any 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 in FIGS Fig. 2 . 4 has been shown schematically. These apertures 36 represent connecting channels 37 between the layers 38, 39 of fillers and adhesives 28 lying above and below the metallic strip 35. These connecting channels 37 are at least partially filled with the filling and adhesive 28 so that they connect the above and below the belt 35 layers 38, 39 of filling and adhesive 28 integrally with each other. 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.

In Fig. 3 is a central procedural measure in the course of the production of a prefabricated semi-finished product 40 schematically illustrated. Such a semifinished product 40 prepared in preparation constitutes a subcomponent for the production of a Fig. 1 illustrated ski 1 or snowboards dar.

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, which materially or adhesively bonded to the underside of the strength-relevant top flange 5. The upper belt 5 may, for example, comprise a so-called prepreg which, under the effect 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 is formed, for example, 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 are 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 a right angle deviating from the flat sides 16, 17 is aligned. In those sections of the longitudinal extent of the core element 7, in which there is a trapezoidal cross-section, the cross-sectional contour thus has a first base side 20 having a first width or length 21 and a substantially parallel, second base side 22 having a second, comparatively shorter width or length 23 on. It is essential that in the course of production of the semi-finished product 40, as in Fig. 3 By way of example, the cross-sectionally trapezoidal core element 7 is adhesively or adhesively bonded to the underside of the strength-relevant top flange 5 or the cover layer 5 such that the first flat side 16 of the core element 7 with the base side 20, which is comparatively longer in cross section, is the strength-relevant top flange 5 is assigned next, whereby the underside facing away from the strength-relevant top flange 5 of the core element 7 is formed by the second flat side 17 of the core element 7 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 also the case with a comparison of FIGS Fig. 2, 3rd 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 form at least one partial section of at least one longitudinal side wall 26, 27 of the final sliding board body 3, are provided with at least one longitudinal side edge 42, 43 of the cover layer 9 or with the adhered to the underside of the cover layer 9 upper belt 5 glued, as shown in particular the schematic representation according to Fig. 3 can be seen. Such a bonding process can be implemented, for example, in the course of a hot pressing or cold gluing process.

In the course of attaching or adhesively bonding at least one strip-shaped side cheek element 29, 29 ', 30, 30' to the underside of the top flange 5 or cover layer 9, a cross-sectionally substantially wedge-shaped intermediate space 24 is created with respect to the core element 7. 25, which is filled in the course of the later completion of the semifinished product 40 to a sliding board body 3 at least for the most part with filling and adhesive 28, as is apparent from a synopsis of Fig. 3 . 4 is apparent. This finally filled with filling and adhesive 28, wedge-shaped space 24, 25 is doing with respect to the width direction of the gliding board body 3, essentially 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 bounded by the adjoining, inclined leg surface 18, 19 of the core element 7, like this best Fig. 4 is apparent. Accordingly, a cross-sectional width 33, 44 of the substantially wedge-shaped intermediate space 24, 25, starting from a top portion 5 nearest the end portion in the direction of the bottom flange 6 nearest end portion dimensioned increasingly larger. This is achieved primarily by the inclined leg surfaces 18, 19 of the core element 7, but can also be reinforced by correspondingly inclined inner surfaces 31, 32 of the longitudinal side walls 26, 27.

Especially in the Fig. 2 . 4 has been illustrated schematically, it is expedient, the smallest cross-sectional width 33 of the cross-section substantially wedge-shaped intermediate space 24, 25 in its upper flange 5 nearest end portion with more than 0.5 mm, preferably between 0.5 mm and 5 mm, preferably with about 1.5 mm.

As in Fig. 5 has been illustrated schematically, it is expedient at least the lateral boundary surfaces of the intended for filling with filling and adhesive 28, wedge-shaped intermediate space 24, 25, in particular the inner surfaces 31, 32 of the at least one strip-shaped side cheek element 29, 29 ', 30, 30' and each roughen the next adjacent leg surfaces 18, 19 of the core element 7 on their surfaces, before these intermediate spaces 24, 25 are filled or filled with the flowable in the original state filling and adhesive 28. As in Fig. 5 schematically illustrated, it is particularly useful to perform 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 directed against the surfaces to be roughened by the action of a compressed air flow. 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 in Fig. 5 is exemplified, is in a subsequent step with the other required for the final sliding board body 3 components, such as the tread 11, the strength-relevant lower flange 6 and optionally connected with edge elements 12, 13, as shown in Fig. 4 was illustrated. In such a joining or manufacturing process for the sliding board body 3, such as a ski 1 or a snowboard, the prefabricated semi-finished product 40 according to Fig. 5 assembled adhesively with the remaining components. In this case, the previously described semifinished product 40, which was produced or constructed according to the previous statements, 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, as its Tread covering 11, the 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 according to Fig. 4 relatively liquid fillers and adhesives 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.

Conveniently, the in Fig. 4 shown severely schematized joining or pressing cycle for adhesive bonding of the semi-finished product 40 with the other 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 alone, 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, using an injection process (RIM) in the shaping molds 46, 47 - Fig. 4 - Introduced 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 of between 1000 to 1200 kg / m ³ , preferably of about 1100 kg / m ³ , and a hardness between 60 to 90 Shore-D, preferably from about 70 Shore D. The particularly efficient or economical curing of the filler and adhesive 28 is achieved inter alia by a filler and adhesive 28 based on polyols and isocyanates to be mixed.

This ensures that the produced Gleitbrettkörper 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 removed 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 pressing device 45 is stored stress-free and stress-free at about room temperature, and thereby the curing time of the filling and adhesive 28 before further processing of the multi-layer sandwich element, especially 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, provided the longitudinal side walls 26, 27 of the composite body 4 with respect to the tread surface 11 trapezoidally inclined or slightly inclined towards the core member 7 extending longitudinal side surfaces 14, 15, as in Fig. 2 in full lines or in Fig. 4 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 approximately 4 °.
