Definitions

  • the invention relates to a device for surfing or the like, in particular a surfboard, with a laminate-coated foam core and a top and bottom having board-like body.
  • surfacing devices with a board-like body so-called surfboards
  • surfboards comprise a laminate-coated foam core having top and bottom surfaces.
  • the resin of the laminations consists of a polyester
  • the foam cores have a lath-shaped device, usually made of wood, the so-called “stringer” for stabilizing the surfboard.
  • the laminate layers usually contain fiberglass fabric and epoxy resin, but these can only be produced in prefabricated forms, without going into the needs of the individual surfer.
  • These surfboards usually have no stringer, as can be accomplished by the epoxy resin in conjunction with commonly used glass fiber fabrics sufficient strength.
  • a surfboard substantially constituted by a core constituting a honeycomb-shaped structure with tensile-strength fibers and a laminate coating surrounding the core discloses a surfboard considered as the closest prior art.
  • DE 41 28 957 A1 discloses a surfboard with a composite body formed by a lightweight body made of a foamed plastic, applied to the core surface hard support layer of a laminating resin or a plastic foam higher density with an embedded plastic in the plastic fabric and an outer skin of an impact resistant, UV Resistant plastic film is formed from a thermoplastic material, wherein the support layer of the board body in the standing area for the surfer contains over the width of the board body extending reinforcing insert through a core layer of a honeycomb material with two outer layers of a single or multi-layer synthetic fiber fabric is formed, this results in a very heavy surfboard sailboard.
  • CH 597 032 apparently a windsurfing board, comprising a laminate-coated foam core and a top and bottom having board-like body, wherein at least the edge region of the left and right side end of the board-like body has at least two fabric laminate layers, one of the bottom to the top to the profile of the corresponding End runs and thus arise in the side edges several cut laminate layers that abut each other, so that no protruding edges.
  • a disadvantage of this is the fact that the joining of two moldings on the Foam core to a surfboard at the seam between the two halves traditionally a vulnerability to the effect occurs that at low surface damage in this area, the foam core can absorb up to about 10% water, which is very difficult to remove by the rapid distribution in the foam body itself This leads to long repair and service life and repairs are possible only to a very limited extent.
  • Problem of the present invention is to avoid, at least in part, the above-mentioned disadvantages, in particular to provide devices and methods for producing generic, in particular these devices for surfing with a board-like body, which have a much longer life compared to conventional surfboards, thus the Risk of board breakage is greatly reduced, with an individual adaptation to the individual surfer is possible.
  • the inventive device for surfing or the like has a board-like body having a laminate-coated foam core and a top and bottom. At least the edge region of the front and / or rear longitudinal end and / or the left and / or right side end of the board-like body has - if appropriate in each case (ie if front and rear longitudinal end and / or right and left side end are concerned) - at least two layers of fabric laminate of which at least one extends from the top to the bottom or vice versa around the profile of the longitudinal end.
  • the device according to the invention has, at least at one of its ends, a substantially increased elasticity compared to conventional surfboards. Due to the multiple - especially double - lamination, the edge regions, in particular the longitudinal ends and / or side ends are considerably more resistant, so that the areas of greatest loads now have a lower probability of breakage. With essential to the invention is the fact that the present devices for surfing in particular at their longitudinal ends and / or side ends have a larger compared to conventional surfboards reversible elongation about the longitudinal axis or transverse axis, so that bumps on the wave to be surfed quasi as a shock absorber be "cushioned".
  • the devices according to the invention are thus faster and more controllable to surf and withstand even the strongest loads in the shaft with deformations up to 30 cm. Furthermore, the devices according to the invention adapt to the ever-changing waveforms of the waves with regard to their longitudinal and / or transverse profile. In addition, the weight is only half of conventional boards.
  • the ratio of total laminate layer thicknesses from top to bottom is in the range of 6: 4 to 5: 5, in particular if the total laminate layer thicknesses of the top and bottom are the same, since these embodiments achieve excellent service lives could, because both an up and a swinging of the longitudinal and / or side ends, at least in almost the same extent possible.
  • the number of laminated fabric layers of the top and bottom are the same size, moreover, if the layer thicknesses of the individual fabric layers are at least almost identical and / or the fabric are chemically similar, so in this way also one allow high and controlled pivoting of the longitudinal and / or side ends.
  • the tissues consist of glass fibers and / or aramid.
  • Aramids are polyamides of aromatic diamines and aromatic dicarboxylic acids, which may also contain imide groups in addition to amide. Aramids are characterized by high thermal and chemical resistance, strength and elasticity as well as good flame resistance and dimensional stability.
  • tissue area weights in the glass fibers in the amount of 80 g / m 2 to 330 g / m 2 and aramid in the amount of 60 g / m 2 to 240 g / m 2 and tissue, the at least one weave from the Group linen, twill 1/3, Twill 2/2, unidirectional correspond, proven.
  • Fabrics, such as fiberglass and aramid fiber fabrics are web-made webs of continuous yarns or twists, the yarns being usually spun with a slight twist (10 to 40 turns per meter), and twines usually being more twisted (100 to 200 turns per meter).
  • an adhesive is applied to the fabric, which serves the better connection with in particular epoxy resins (epoxy resins).
  • epoxy resins epoxy resins
  • the weave is the type of thread binding in warp (longitudinal) and weft (cross) direction.
  • the linen weave is a simple ground weave in which the weft crosses one warp thread at a time. It ensures good dimensional stability and low fraying when cutting.
  • the Twill weave skips several warp threads, resulting in highly conformable and drapeable fabrics that are particularly well-suited to curved shapes but are less easy to cut.
  • Tissues are called unidirectional if these contain thin weft threads, so that more warp threads can be accommodated at the same resin content in the laminate. Because of the thread stretch is thus obtained in the longitudinal direction a significantly higher strength and rigidity.
  • the laminate layer when the laminate layer is broken when the foam core is exposed, it does not swell excessively on contact with water or absorbs water, and the latter has a closed cell structure, which is accomplished by modifying the foam by means of customary additives.
  • the inner surface of the foam core is substantially dust-free, since in the lamination of the first fabric layer on the foam core in this way an extremely intimate connection is made, otherwise with existing dust particles, the adhesion of the laminate on the foam core greatly reduced would and would often lead to delamination.
  • the forces are absorbed directly from the glass fibers or aramid (for example in the form of fibers), so that usually deformations up to about 30 cm (! Are possible.
  • the material thickness of the top and bottom could be significantly reduced due to the above-mentioned, at least in the edge region performed multiple lamination.
  • the weight of the device according to the invention could be significantly reduced compared to conventional boards, with stringerivaer execution even by half. The life of these devices should have been increased by about a factor of 4 compared to conventional boards.
  • the board-like body of the device according to the invention after appropriate use footprints of the surfer (footprints) on.
  • the resulting prints range from 2 to 8 mm in depth and then stagnate without adversely affecting the quality of the board, providing optimum transfer of force from the foot to the board.
  • the footprints do not lead, as usual, to later delaminations of the laminate from the foam core.
  • the overlap of the fabric laminate layers in the edge region of the board-like body extends in the circumferential direction only over part of the length of the body in this direction.
  • the overlap may be formed in a plurality of short, circumferentially successive and spaced-apart areas.
  • the board-like body is provided in the region of its surface, in particular on its surface, with a UV-resistant material.
  • the UV-resistant material may be contained in the laminate or form a coating of the board-like body.
  • the device according to the invention is preferably a surfboard.
  • the device according to the invention may also be, for example, a skim board, a wake board, a wake skate, a kite board, a knee board, a body board, a windsurf board, a water ski, a monoski or other similar sports equipment.
  • Fig. 1 shows a sketch of a first embodiment of the device according to the invention.
  • a foamed polyurethane foam core 1 is laminated at the right longitudinal end with two fabric webs 2, 3 in such a way that the upper fabric web 2 laminating from the top to the bottom and the lower fabric web 3 from bottom to top around the profile of the longitudinal end are arranged.
  • the fabrics are glass filament fabrics with a basis weight of 163 g / m 2 (weave: linen) (source: Lange + Ritter).
