Definitions

  • the invention relates to a sliding board sports equipment according to the preamble of claim 1 and a manufacturing method for a Gleitbrettsport réelle according to the preamble of claim 18th
  • Skis and snowboards generally consist of a top chord and a bottom chord, between which a core is arranged.
  • the core, the top and bottom chords are made of wood, or the top and bottom chords are made of laminates, such as fiberglass or carbon fiber constructions, in which case the core can also be made of an elastomeric foam.
  • the constructions consisting of foamed, non-load-bearing cores in connection with external high-strength laminates have replaced the conventional wooden constructions in recent decades.
  • a ski is described, which consists of a foamed plastic core with an enveloping, supporting structure.
  • the laminated structures generally do not have good damping properties, which can lead to unpleasant vibrations during driving.
  • the materials used are poor or not recyclable, so these skis and snowboards have a poor life cycle assessment.
  • Another disadvantage is that the core has a pure filling function, ie the weight of the core increases that Total weight without the core contributing to the stability of the construction.
  • FR-A-2 429 377 discloses board sports equipment partly made of bamboo.
  • the invention is based on the object to develop an improved Gleitbrettsport réelle, in particular a ski, a snowboard, a water ski, a wakeboard or kiteboard, with which the disadvantages of conventional Gleitbrettsportieri be avoided and the simplest possible production and high rigidity improved Life Cycle Assessment and improved driving characteristics.
  • the object is achieved with a Gleitbrettsporthold according to claim 1 and a manufacturing method for such Gleitbrettsportperformance according to claim 17.
  • the invention is based on the physical knowledge that the choice of a suitable material for the core of Gleitbrettsportuzes, such as a ski, snowboards, water skis, wakeboards or kite boards damping properties, driving characteristics and life cycle assessment can be improved.
  • the core of the Gleitbrettsportuzes invention consists at least partially of bamboo.
  • bamboo is a fast-growing, recyclable raw material that can absorb high tensile, compressive and torsional loads.
  • bamboo is a low-cost material that is easy to work with. This advantageously results in an inexpensive production.
  • the laminates can either be dispensed with completely, or they can be made in a smaller thickness, which further improves the LCA. By reducing or eliminating the laminate layers In addition, the total weight can be reduced.
  • the weight reduction made possible by the bamboo structure is of particular advantage, since the ski, unlike the snowboard, is connected to one leg only fixed in one place. Even a slight reduction in weight is particularly noticeable in a ski, since the mass moment of inertia of the ski around the axis of the leg which is decisive for torsional loads on the leg is disproportionately reduced.
  • the core consists partly or wholly of bamboo slats.
  • the bamboo slats may have a rectangular cross-section or even another cross-section, for example with six or a different number of corners.
  • the bamboo slats can be square bamboo sticks, which are installed side by side in the core and glued together. This construction has the advantage of being very easy to manufacture.
  • the use of solid square bamboo slats achieves maximum rigidity of the core.
  • the core may also or exclusively comprise angle-milled bamboo tubes.
  • Angled milled bamboo can be made, for example, from bamboo cane with the help of a square milling machine. This results in a square bamboo rod having a cavity inside, wherein the size of the cavity is dependent on the size of the cavity of the bamboo tube used for the production.
  • the angle-milled bamboo tubes can be arranged in the core side by side or side by side and one above the other so that a specific core cross-section is formed.
  • the advantage here is the weight reduction due to the cavities of the angle-milled bamboo tubes.
  • Angularly milled bamboo tubes are used with a thickness that corresponds to the thickness of the core.
  • a filler of lesser density than bamboo can be arranged in the core.
  • This has the advantage that the weight of the core can be reduced.
  • a filling material known foamed plastics or natural products can be used.
  • the Gleitbrettsport réelle has a layer structure in which above and below the core, an at least partially made of bamboo inner veneer layer is arranged.
  • This veneer layer can consist entirely or partially of square bamboo sticks, which have been glued together, for example.
  • the veneer layers, in combination with the core, give the snowboard, the ski, the water ski, the wakeboard or the kiteboard a very high degree of rigidity, since a torsionally rigid box is created in a non-positive connection with the core.
  • the veneer layers are fixed directly to the core without laminates, without a laminate layer being arranged. This has the advantage that can be dispensed with in this area on laminate layers that would deteriorate the environmental balance. If an increased rigidity of the construction is desired, but can Laminate around the core or the inner veneer layers are arranged.
  • an upper and a lower chord are arranged according to the invention, which consist at least partially of bamboo.
  • the upper and lower chords increase the rigidity of the construction, whereby, if required, several upper and lower chords can be arranged.
  • the upper and lower chords can also be made of a material combination of bamboo with, for example, a laminate, and a combination with other natural materials such as wood is also possible in order to increase the strength at certain points.
  • the upper and lower chords are each mounted directly on the inner veneer layer. If the inner veneer layers are mounted directly on the core, this results in a stack or sandwich construction which is free of laminates and yet highly stable.
  • the bamboo of the core, the lower chord, the upper chord or the inner veneer layers is unthreaded in the longitudinal direction.
  • the longitudinal direction refers to a direction of travel of the ski, the snowboard, the water ski, the wakeboard or the kite board. Since impact is generally difficult to transfer and thrust transfer, a bum-free construction offers the advantage of consistently high strength. However, if impacts due to structural details are necessary, they are arranged as possible staggered to ensure a continuous power transmission in the components in the longitudinal direction.
  • square bamboo rods or angularly milled bamboo tubes are used made of bamboo tubes whose length is greater than the length of the Gleitbrettsportuzes to be produced.
  • side cheeks are arranged laterally of the core, which laterally cover the core or the inner veneer layers.
  • the top flange and the bottom flange are wider than the core with the inner veneer layers and are also non-positively connected to the side cheeks, for example glued. This creates a torsion box, which increases the rigidity of the construction.
  • Sideways means in the longitudinal direction of Gleitbrettsportêts next to the core.
  • vapor barriers are arranged on the core side of the side cheeks.
  • the vapor barriers lie between the core and the sidewalls and prevent the entry of water into the core.
  • inner veneer layers are arranged above and below the core, the vapor barriers also advantageously cover these veneer layers in order to reliably protect the core and the veneer layers against lateral water ingress.
  • the vapor barriers may also be bamboo, which may be specially treated to resist water. If the bamboo vapor barrier connected non-positively with the inner veneer, so advantageously creates a box that increases the torsional stiffness of the snowboard, the ski, the water ski, the wakeboard or the kite board.
  • the core advantageously has special features in order to absorb the high forces that are exerted on the binding on the sliding board sports device.
  • the core may have wood in the load transfer area, in particular, higher-strength wood types are beneficial. For example, a massive location can Beech wood to be glued.
  • the inner veneer layers, the upper or the lower flange wood may also have a force introduction.
  • the load introduction area may, for example, each attachment device have a size of about 5 x 5 cm, but it may also be much larger, for example. Have a length of 60 cm. If the core is made of square-edged bamboo tubes, replacement of square-edged bamboo tubes with solid bamboo slats in the load-transfer area can also be advantageous, as it increases the strength in this area.
  • the upper belt can be at least partially enclosed with a metallic cover.
  • the metallic cover can run in the region of the upper edge and, for example, consist of Titanal. Titanal has the advantage that it has a high resistance to mechanical attacks at low density.
  • adjacent bamboo parts are provided in the core with alternately opposite growth directions with respect to the longitudinal direction of the sports equipment, there may be advantages for increased stability of the core structure.
  • the bamboo used for these components preferably has a tensile strength of at least 20 kN / cm 2 , 30 kN / cm 2 or 40 kN / cm 2 , a tensile elastic modulus of at least 2.0 MN / cm 2 , 2.5 MN / cm 2 or 3.2 MN / cm 2 or a fiber length of at least 1 cm.
  • a high modulus of elasticity has the advantage that the Gleitbrettsport réelle a high rigidity is awarded.
  • a high tensile strength in turn has the advantage that the Gleitbrettsport réelle has a high strength. The higher the strength, the higher the sliding board sports equipment can be loaded. Long fibers increase the resistance and strength of the bamboo.
  • the Gleitbrettsport réelle has a cover layer which is disposed above the upper flange.
  • This cover layer protects the underlying layers against mechanical influences, such as, for example, knocks.
  • the cover layer is preferably made at least in part from bamboo of the genus "Phyllopstachys pubescens" or a similar genus. By using bamboo in combination with a transparent protective layer, an attractive graphic design of the snowboard can be achieved.
  • the bamboo used for the top layer should have a Brinell hardness of at least 32 HB.
  • the bulk density of the bamboo used is preferably at least 0.79 g / cm 3 .
  • the abrasion resistance of the cover layer is higher than 3.7. This achieves a high resistance to mechanical grinding loads.
  • a protective layer is advantageously applied, for example, to the cover layer.
  • This protective layer may, for example, consist of a two-component lacquer or a plastic sealing system and protects the surface against moisture, mechanical effects and UV radiation.
  • Particular advantages for the protection and the visual appearance of the surface may result if the protective layer is formed from a protective oil, in particular linseed oil. The oil-protective layer can penetrate into the material below the surface, so there is less chance of injury of deeper layers and superficial scratches can be easily corrected.
  • a manufacturing method for producing a Gleitbrettsportmixs invention is an independent subject of the invention.
  • the bamboo used to manufacture a sliding board sports equipment according to the invention should generally have a fiber length of at least 1 cm, at a height of no more than 2000 m above sea level, have a maximum residual moisture of 10%, are stored vertically after being whipped and air-dried over a period of 4 to 6 weeks, beaten for a cool and dry season, and heavily silicified nodiums Have diaphragms.
