7505 Ettlingen 2. Gustav Waldenberger, Karl-Delisle-Str. 11, 7500 Karlsruhe 21 Surfbrett 1?ie Erfindung betrifft ein als geschlossener Bootskörper ausgebildetes Surfbrett mit mindestens einer, endständig an der Unterseite vorgesehenen Finne. 7505 Ettlingen 2. Gustav Waldenberger, Karl-Delisle-Str. 11, 7500 Karlsruhe 21 Surfboard 1? The invention relates to a closed boat body trained surfboard with at least one terminal provided on the underside Fin.
Der Surfsport, also das Ausüben des Windsurfing, findet immer mehr Anhänger. Dadurch bedingt werden die Leistungsanforderungen an Spitzensportler auch immer höher gestellt beziehungsweise es werden auch immer höhere Anforderungen an die zur Ausübung dieses Sportes benötigten Surfbretter gestellt. So konnte auch die hydrodynamische Güte derartiger Surfbretter stetig verbessert werden und damit auch die Möglichkeit zu verbesserten Fahrleistungen. Die Grenze der Fahrlei- stungen bei den Surfbrettern üblicher Länge wurde allerdings durch die Windgeschwindigkeit beziehungsweise die Rauhigkeit des Wassers bestimmt. Große Windstärken und damit verbunden große Wellenhöhe lassen sich mit normal langen Surfbrettern nicht mehr meistern; hierzu werden kurze Surfbretter, sogenannte "Starkwind"-Surfbretter benötigt. Diese etwa 3,25 bis 3,30 Meter langen Bretter können allerdings mit Vorteil nur bei starkem Wind und rauher See gefahren werden; bei schwachem Wind und einer dementsprechenden WasseroberflEche sind die normal langen Surfbretter deutlich im Vorteil.Surfing, i.e. practicing windsurfing, is becoming more and more popular Pendant. This also results in the performance requirements for top athletes ever higher or there are also ever higher demands on the surfboards required to practice this sport are provided. So could too the hydrodynamic quality of such surfboards are constantly being improved and thus also the possibility of improved driving performance. The limit of the cantilever stungen with the surfboards of the usual length, however, was due to the wind speed or determines the roughness of the water. Great wind forces and thus The associated high wave heights can no longer be achieved with normal long surfboards master; this requires short surfboards, so-called "strong wind" surfboards. These boards, which are around 3.25 to 3.30 meters long, can only be used with advantage be driven in strong winds and rough seas; with weak wind and a corresponding one On the water surface, surfboards of normal length have a clear advantage.
Um bei sämtlichen Wetterlagen surfen zu können, sind die Surfer daher angewiesen, sich zwei Surfbretter zu kaufen, wobei das Rigg in aller Regel für beide Bretter gleich sein kann. Der Zwang zur Verwendung zweier Bretter für entsprechende Wetterlagen ist jedoch nicht nur ein Kostenfaktor, sondern, insbesondere bei UrletubsSahrten, ein Transportproblem. Gerade aber bei Urlubsfahrtcn, die in aller Regel an das Meer führen, wo fast stets Schwach- und Starkwind-Wetterlagen abwechseln, möchte der Surfer über beide Surfbrettarten verfügen.In order to be able to surf in all weather conditions, the surfers are therefore instructed to buy two surfboards, with the rig usually for both Boards can be the same. The compulsion to use two boards for appropriate However, weather conditions are not only a cost factor, but, especially in the case of UrletubSahrten, a transportation problem. But especially with vacation trips, which are usually to the sea He wants to lead, where almost always weak and strong wind weather conditions alternate Surfers have both types of surfboards.
Hier greift die Erfindung ein, indem sie ein Surfbrett angibt, bei dem der Bootskörper aus einem Rumpfvorderteil und einem, fest aber lösbar mit ihm zusammengefügten Heckteil besteht.This is where the invention intervenes by specifying a surfboard that of the hull of a hull front part and one, fixed but detachable with it assembled rear part consists.
Nicht mehr also wie bisher ist der Surfer gezwungen, zwei Bretter zu verwenden, sondern er benutzt ein aus diesen beiden Teilen zusammengefügtes normal langes Surfbrett, das er bei Starkwind-Wetterlagen um das angeSAgte Heckteil verkürzt. Da das Rigg in beiden Fällen gleichbleiben kann und es bei diesen Starkwind-Surfbrettern erwünscht ist, daß der Lateralschwerpunkt weiter zum Heck verschoben ist, ergibt sich durch diese einfache Maßnahme ein universell verwendbares Sportgerät, das sowohl bei extrem schwachwindigen, wie auch starkwindigen Wetterlagen einsetzbar ist.So the surfer is no longer forced to two boards to use, but he uses a normal made up of these two parts long surfboard, which he shortens around the stern section in strong winds. Because the rig can stay the same in both cases and it can with these strong wind surfboards it is desirable that the lateral center of gravity moved further to the stern is, this simple measure results in a universally usable piece of sports equipment, that can be used in extremely weak winds as well as strong winds is.
Zweckmäßigerweise wird die Länge des Heckteils zwischen dem 0,3 und 1-fachen der größten Breite des Bootskörpers gehalten, um den im mitteleuropäischen Klima vorkommenden Wetterlagen gerecht zu werden.Appropriately, the length of the rear part is between 0.3 and 1 times the greatest width of the hull, around that of the Central European To do justice to the weather conditions that occur in the climate.
Zum einfachen Montieren beziehungsweise Demontieren des Heckteils wird nach der Erfindung vorgeschlagen, daß das Heckteil mit längsverlaufenden Justierbolzen und das Rumpfvorderteil mit entsprechenden Justierhülsen versehen ist. Eine einfache, zweckmäßige und sichere Verbindung der beiden Teile ergibt sich hierbei dadurch, daß eine zentrale Befestigungsschraube schräg verlaufend das Heckteil durchdringend, in das Rumpfvorderteil einschraubbar ist. Um eine saubere Abreißkante am Heck zu erzielen, aus ästhetischen Gründen und um auch die Befestigung mit der zentralen Befestigungsschraube zu optimieren, empfiehlt es sich, daß die Trennflächen zwischen den beiden Teilen - Rumpfvorderteil und Heckteil - schräg zur Längsebene des Bootskörpers verläuft.For easy assembly or disassembly of the rear section it is proposed according to the invention that the rear part with longitudinal adjustment bolts and the front part of the fuselage is provided with corresponding adjustment sleeves. A simple Appropriate and safe connection of the two parts results from the fact that that a central fastening screw running diagonally penetrating the rear section, can be screwed into the front part of the fuselage. To get a clean tear-off edge at the stern achieve, for aesthetic reasons and also to attach to the central To optimize fastening screw, it is recommended that the interfaces between the two parts - the front part of the hull and the stern part - at an angle to the longitudinal plane of the hull runs.
Die endständig an der Unterseite vorgesehene Finne muß boi dieser Ausführung selbstverständlich endständig am Rumpfvorderteil vorgesehen sein. Um jedoch auch bei schwachwindigen Wetterlagen eine gute Stabilisierung zu erzielen, wird nach der Erfindung weiterhin vorgeschlagen, daß sowohl endständig am Rumpfvorderteil, wie auch am Heckteil mindestens je eine Finne vorgesehen ist.The fin provided at the end on the underside must be this Execution of course be provided at the end of the fuselage front part. Around however, to achieve good stabilization even in weak winds, it is further proposed according to the invention that both terminally on the front part of the fuselage, as well as at least one fin is provided on the rear part.
Auf der Zeichnung ist ein Ausführungsbeispiel des Er- findungsgegenstandes schematisch dargestellt, und zwar zeigen: Fig. 1 die Seitenansicht eines Surfbrettes und Fig. 2 eine Teilansicht bei II der Fig. 1.The drawing shows an embodiment of the object of invention shown schematically, namely: Fig. 1 is a side view of a surfboard and FIG. 2 is a partial view at II of FIG. 1.
Das Surfbrett nach der Erfindung ist gebildet aus einem Rumpfvorderteil 2 und einem, an dieses Rumpfvorderteil 2 angefügten Heckteil 3. Endständig sowohl am Rumpfvorderteil 2, wie am Heckteil 3 ist an der Unterseite je eine Finne 4 vorgesehen. Die Trennstelle ist in Fig. 2 im Schnitt dargestellt. Die schräg verlaufende Trennfläche 5 wird, um eine starke Flächenpressung zu erzielen, von jeweils einem, am Rumpfvorderteig 2 und am Heckteil 3 angeordneten Rahmen 6, 7 gebildet. Im Heckteil 3 sind Justierbolzen 8 vorgesehen, die in eine, im Rumpfvorderteil 2 eingearbeitete Hülse 9 eingreifen. Für den festen Sitz der beiden Teile 2, 3 zueinander sorgt eine zentrale Befestigungsschraube 10, die das Heckteil 3 durchdringt und in eine Gewindehülse 11 im Rumpfvorderteil 2 einschraubbar ist.The surfboard according to the invention is formed from a front part of the fuselage 2 and a stern part 3 attached to this front part of the fuselage 2. Both ends at the end On the fuselage front part 2, as on the rear part 3, a fin 4 is provided on the underside. The separation point is shown in section in FIG. The sloping dividing surface 5, in order to achieve a strong surface pressure, one at a time on the front dough 2 and frame 6, 7 arranged on the rear part 3. Adjusting bolts are located in the rear part 3 8 are provided, which engage in a sleeve 9 incorporated in the front part 2 of the fuselage. A central fastening screw ensures that the two parts 2, 3 are firmly seated to one another 10, which penetrates the rear part 3 and into a threaded sleeve 11 in the front part of the fuselage 2 can be screwed in.
In der gezeigten Darstellung ist das Surfbrett 1 zur üblichen Verwendung bei normalem Wind geeignet. Bei starkem Wind hingegen wird das Heckteil 3 durch Lösen der Befestigungsschraube 10 entfernt, wodurch gleichzeitig der Lateralschwerpunkt, der im wesentlichen etwa am Anlenkpunkt des Mastes 12 liegt, heckwärts wandert, wodurch die Beherrschung des Surfbrettes wesentlich erleichtert wird.In the illustration shown, the surfboard 1 is for normal use suitable for normal winds. In the case of a strong wind, however, the rear part 3 is through Loosening the fastening screw 10 removed, whereby at the same time the lateral center of gravity, which is essentially at the point of articulation of the mast 12, migrates stern, whereby the control of the surfboard is made much easier.
