Definitions

  • the invention relates to a surfboard, in particular a windsurf board with a board body made of plastic and plastic foam and with units connected to the board body, such as a sword case, mast foot sleeve, foot straps, fins etc.
  • Surfboards especially Wi.ndsurfboards of this type are generally known.
  • Known surfboards basically consist of a foam core and an outer skin that completely encloses it.
  • the foam cores can be PU foams, polystyrene foams or other light plastic foams.
  • Known outer skin materials include polyethylene, glass fiber reinforced plastic, and epoxy laminates. Surfboards are also known which consist of foamed polyester half-shells.
  • the known windsurf boards have a number of disadvantages, which lie in particular in the high weights. Another disadvantage is that it is not possible to use reinforcements in the form of To provide frames, stringers or the like. Because of the relatively high weight of the foam used, efforts are also made to keep the outer skin as thin as possible in order to solve the weight problems mentioned. This again results in a comparatively high impact sensitivity of such boards.
  • a significant disadvantage of the prior art is also that the above-mentioned, sometimes considerable mechanical stress-absorbing units can hardly be safely connected to the known windsurfing boards, since - as is evident from the described construction according to the prior art - only can be anchored to a comparatively weak foam core and, at best, two thin, mechanically stronger outer skin layers. In the case of industrially manufactured windsurf boards, the production is also burdened with high molding costs, so that correspondingly expensive new molds have to be created to change the board shape.
  • the invention has for its object to provide a surfboard, especially windsurfing board of the type specified above, which does not have the disadvantages mentioned.
  • the surfboard consists of an essentially rigid base element made of a mechanically solid material and an upper part connected or connectable to the base element made of a flexible light plastic, in particular plastic foam, and that all units are connected to the floor element.
  • the advantage is thereby achieved that the risk of injury is considerably reduced when using a skin-friendly, flexible, light plastic for the upper part.
  • the flexibility of such a surfboard can be optimally determined over the length without difficulty and even changed by simply connecting additional stiffening elements to the bottom plate before the top part is connected to the bottom element.
  • the rigid mechanically strong material which has a high specific weight compared to the plastic foam, is only used on the underside of the surfboard, a considerable weight saving is possible. It is expected that with a total volume of about 260 liters of such a windsurf board, weights between 12 and 14 kg can be achieved.
  • the base element with a raised central rib which contains the attachment points of the units and the sword case.
  • the invention can be further developed in that the base element is provided with stringers.
  • a bridge-like component is preferably molded onto the base element.
  • This embodiment offers the advantage that the main standing surface of a windsurfing board experiences additional stiffening, whereby. in an advantageous further development, this bridge-like component can be hollow, can contain an inflatable bladder or can be foamed with a particularly light foam. As a result, the advantage of further weight savings is achieved with the highest mechanical strength.
  • foot straps can then be attached in this area without difficulty, which, according to the invention, are then connected to the base element via the bridge-like component and not to the foam core as previously.
  • support ribs can also be provided within the bridge-like component.
  • the base element can preferably be produced as a deep-drawn part made of ABS, as a molded part made of polyethylene foam sandwich material, of integral polyurethane foam, of SMC (sheet molding compound) or of wood or partly wood.
  • the material to be selected depends on the properties of flexibility and strength required on the end product.
  • the upper part preferably consists of a skin-friendly material, in particular plastic foam, such as, for example, polyethylene foam or other flexible foams.
  • plastic foam such as, for example, polyethylene foam or other flexible foams.
  • the upper part is designed to be removable and replaceable.
  • changes in the total volume, changes in shape, in particular the shape of the surface and standing area can be easily produced.
  • the upper part is foamed or glued to the base element.
  • the upper part covers substantially the entire surface of the windsurf board to reduce the risk of injury.
  • only the front part of the windsurfing board can be covered by the upper part, while the standing area is formed by the bridge-like component already mentioned.
  • the base element is designed as a flexible base plate and has coupling pieces for differently shaped stringers or longitudinal ribs.
  • a wide variety of board shapes can be produced using one and the same base plate, for example by connecting the base plate to a correspondingly pre-shaped longitudinal rib in a tongue and groove connection.
  • Another object of the invention is a method for producing a surfboard, in particular windsurfing boards from the above description, which is characterized in that a base element is made of a mechanically strong material which contains all the attachments of the units such as sword box, fin, mast foot, etc., and that the bottom element is then connected to an upper part made of a plastic foam or the like.
  • a windsurf board according to the present invention consists of two main components, namely a bottom element 2 and an upper part 3.
  • the bottom element 2 is produced from a mechanically stable material by a suitable molding process.
  • suitable molding process are, for example, ABS, polyethylene foam sandwich, integral polyurethane foam, SMC (sheet molding compound) or wood or wood paired with one of the plastics mentioned.
  • the base element 2 made of the mechanically solid material contains all the aggregates or attachment points for aggregates that are usually present, such as are present in such windsurf boards, namely, for example, the mast sockets 4, the sword case 5, and attachments 6 for foot straps.
  • the bottom element 2 contains at least one central rib 7, which is designed according to the desired flexibility of the windsurf board 1.
  • the base element 2 can also contain additional stringers, both the central rib 7 and the stringers not necessarily having to be formed in one piece with the base element 2.
  • dovetail-shaped grooves or similar coupling pieces can be provided for this purpose in the base element 2, into which corresponding coupling sections of the stringer or the central rib 7 can be inserted.
  • the base element 2 in the area of the stern 8 has a bridge-like component 9, which is likewise either formed in one piece with the base element 2 or can be connected to the latter via corresponding coupling sections. Details of this bridge-like section 8 are referred to below.
  • the bottom element 2 also has raised edges 11, 12 on the sides, which can have the edge-like sharp transitions to the bottom or the front keels of the underwater hull of the windsurf board 1 which are desired for many board types.
  • the upper part 3 illustrated by way of example in FIG. 1 preferably consists of an elastic skin-friendly material of low specific weight. Examples of such materials are polyethylene foam or other types of foam, rubber, neoprene or other flexible materials. On the other hand, the upper part 3 can also consist of an inflatable rubber or plastic bladder. The upper part 3 can either be foamed directly onto the base element 2 in the manufacture of the windsurfing board 1 or can be produced as a separate component and later connected to the finished base element 2. Possibilities of the connection between the upper part 3 and the base element 2 are explained in more detail below.
  • the upper part 3 at least as far as the units 4, 5, 6 are concerned, is not exposed to any mechanical stresses and can therefore be chosen optimally in terms of skin friendliness and low weight.
  • the upper part 3 according to FIG. 1 is also provided with corresponding cutouts 13, 14, 15 which correspond to the units 4, 5, 6. Furthermore, self-ver of course the upper part 3 adapted in shape to the corresponding surface of the base element 2 with which it is joined.
  • FIGS. 4 and 5 show a strong wind board of small volume, while the volume of the windsurf board 1 according to FIGS. 4 and 5 is considerably larger due to the corresponding design of the upper part 3.
  • FIG. 1 For further details, reference is made to the description of FIG. 1.
  • this connection can be, for example, a type of button connection, in which coupling parts 16 fastened to the base element 2 at corresponding points can be connected to correspondingly shaped openings 17 in the upper part 3.
  • FIGS. 7 to 12 illustrate two further embodiments according to the invention, in which the upper part 3 only partially forms the deck surface 18 of the windsurf board 1. As in the other embodiments, all units are 13 to 15 Be Part of the bottom element 2, while the main volume of the windsurf board 1 is formed by the upper part 3.
  • the standing area behind the mast base sleeves 4 is formed by the bridge-like component 9, which, as a continuation of the central rib 7, also holds the sword case 5 or the foot straps 19 indicated in FIG. 7.
  • the bridge-like component 9 can, as indicated in FIG. 7, be foamed with a light plastic foam 20.
  • an inflatable air envelope (not shown) can be inserted in the cavity between the floor 21 and the bridge-like component 9 of the floor element 2. Furthermore, it is also possible not to fill this space or, if necessary, to brace it with support ribs 22, as indicated in FIG. 11.
  • the desired longitudinal flexibility of the finished windsurfing board can also be optimized by attaching corresponding stiffening elements.
  • stiffening elements aluminum components or the like can also be used without difficulty. install with. Because all mechanical forces of the associated units are borne by the mechanically firm floor assembly the plastic foam that forms the actual buoyant volume of the windsurfing board 1 can be selected without regard to its mechanical strength.
