Derartige Segelbretter sind z. B. aus der DE 29 28 579 A1 bekannt. Der Schaumkunststoffkern dieser Bretter ist als Leichtbauformteil gestaltet und vorzugsweise aus Styrol hergestellt. Hierdurch soll das Gewicht der Segelbretter gering gehalten werden, wodurch sie einmal ein günstiges Fahrverhalten haben und zum anderen einfach und leicht zu transportieren sind. Zum leichten Transport und zur besseren Lagerung dienen auch Ausführungen gemäß der vorgenannten Schrift, bei denen die Segelbretter aus verschiedenen Sektionen zusammengesetzt sind. Vorzugsweise sollen hierbei Leichtbauform­ teile ausschließlich im Vorderteil und Hinterteil des Segelbretts vorgesehen sein. Weiter ist noch eine Konstruktion vorgeschlagen mit zweiteilig ausgebildeten und innen hohlen Leichtbauform­ teilen.Such sailing boards are e.g. B. known from DE 29 28 579 A1. The foam plastic core of these boards is a lightweight part designed and preferably made of styrene. This is supposed to the weight of the sailing boards can be kept low, which makes them on the one hand have a favorable driving behavior and on the other hand simply and are easy to carry. For easy transportation and better storage also serve designs according to the aforementioned Scripture in which the sailing boards from different sections are composed. Preferably, lightweight design should be used parts only in the front and rear of the sail board be provided. A construction is also proposed with a two-part design that is hollow on the inside share.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, ein gattungsgemäßes Segelbrett, dessen Außen­ schale mit einem zweiteiligen Schaumkunststoffkern ausgefüllt ist, so auszubilden, daß es bei geringem Gewicht eine hohe Stabilität besitzt. Based on this prior art, the invention lies Task based on a generic sailboard, the outside shell is filled with a two-part foam plastic core, to be designed so that it is very stable and lightweight owns.  

Dies ist erfindungsgemäß durch das kennzeichnende Merkmal des Patent­ anspruchs 1 erreicht. Zweckmäßigerweise sind die Ausnehmungen durch gewölbte Wandungen begrenzt, die den Oberflächen der Kernhälften eine gute Festigkeit verleihen. Die Ausnehmungen können wabenförmig angeordnet sein.According to the invention, this is due to the characteristic feature of the patent claim 1 reached. The recesses are expediently through arched walls bounded by the surfaces of the core halves give good strength. The recesses can be honeycomb-shaped be arranged.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß die Kernhälften mit miteinander fluchtenden, längsverlaufenden und vor den Oberflächen endenden spaltförmigen Öffnungen versehen sind, in die längsverlaufende und hochkant stehende Stege aus biege­ steifem Material eingeklebt werden. Derartige sogenannte Stringer führen nicht nur zu einer zusätzlichen guten Verbindung der Kern­ hälften, sie weisen auch ein großes Flächenträgheitsmoment auf, so daß dem Segelbrett eine große Biegesteifigkeit um seine Querachse verliehen wird.According to an advantageous embodiment of the invention, that the core halves with aligned, longitudinally running and provided in front of the surface ending gap-shaped openings bend into the longitudinal and upright webs stiff material. Such so-called stringer not only lead to an additional good connection of the core halves, they also have a large area moment of inertia, so that the sailboard has great flexural rigidity about its transverse axis is awarded.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. In dieser zeigtAn embodiment of the invention is described below with reference to the Drawing explained in more detail. In this shows

Fig. 1 einen Querschnitt durch ein Segelbrett aus zwei Halb­ schalen mit einem von diesen umschlossenen Schaum­ kunststoffkern, Fig. 1 is a cross-sectional view of a sailboard of two half shells with a space enclosed by these foam plastic core,

Fig. 2 eine der Fig. 1 entsprechende Querschnittshälfte mit einem in eine umlaufende Nut des Kerns eingelegten Schlauch und Fig. 2 is a cross-section corresponding to FIG. 1 with a hose inserted into a circumferential groove of the core and

Fig. 3 eine perspektivische Ansicht eines Teils einer Kernhälfte. Fig. 3 is a perspective view of part of a core half.

Wie aus Fig. 1 ersichtlich ist, bilden eine obere Halbschale 3 und eine untere Halbschale 4 die Außenschale des Segelbretts. Die untere Halb­ schale 4 weist an ihrem Rand einen Absatz auf, der durch die Stirn­ seite 5 des Randes und eine eingezogene hochstehende Lippe 6 gebildet ist. Die obere Halbschale 3 stößt mit der Stirnseite 7 ihres Randes stumpf auf die Stirnseite 5 des Randes der Halbschale 4, so daß der Rand der Halbschale 3 in der durch die Stirnseite 5 und die hochgezogene Lippe 6 gebildeten Stufe liegt.As can be seen from FIG. 1, an upper half-shell 3 and a lower half-shell 4 form the outer shell of the sailing board. The lower half shell 4 has at its edge a paragraph which is formed by the front side 5 of the edge and a raised lip 6 . The upper half-shell 3 abuts the end face 7 of its edge butt against the end face 5 of the edge of the half-shell 4 , so that the edge of the half-shell 3 lies in the step formed by the end face 5 and the raised lip 6 .

Vor dem Zusammenfügen der Halbschalen 3, 4 sind deren inneren Wan­ dungen mit einem Klebstoffauftrag 8 versehen worden. Anschließend wurden die Kernhälften 9, 10 des in seiner mittleren Ebene geteilten Schaumkunststoffkerns auf die Klebstoffschichten 8 aufgedrückt. Die Kernhälften sind mit miteinander fluchtenden Ausnehmungen 11, 12 ver­ sehen, die ein aus Fig. 3 ersichtliches Wabenmuster bilden können. Die Stirnseiten der Stege 13 der oberen Kernhälfte sind mit Zapfen 14 versehen, die mit entsprechenden Ausnehmungen 15 in den Stirnseiten der Stege 16 der unteren Kernhälfte 9 fluchten. Vor dem Zusammenfügen der Kernhälften wurde in die Ausnehmungen 15 Klebstoff eingefüllt. Im Bereich der hochgezogenen umlaufenden Lippe 6 weist der durch die Kernhälften gebildete Schaumkunststoffkern eine umlaufende Nut 17 auf, die mit einem Schaumkunststoff ausgespritzt ist. In die Kleb­ stoffschicht 8 können zur Stützung der Halbschalen 3, 4 Glasfaser­ gewebe oder -matten eingelegt sein, so daß sich gleichsam in Form eines Laminats eine zusätzliche tragende Oberflächenschicht ergibt.Before the half-shells 3, 4 are joined together, their inner walls have been provided with an adhesive application 8 . The core halves 9, 10 of the foam plastic core divided in its middle plane were then pressed onto the adhesive layers 8 . The core halves are seen with aligned recesses 11, 12 ver, which can form a honeycomb pattern shown in FIG. 3. The end faces of the webs 13 of the upper core half are provided with pins 14 which are aligned with corresponding recesses 15 in the end faces of the webs 16 of the lower core half 9 . Before the core halves were joined, 15 adhesive was filled into the recesses. In the area of the raised circumferential lip 6 , the foam plastic core formed by the core halves has a circumferential groove 17 which is sprayed with a foam plastic. In the adhesive material layer 8 , glass fiber fabrics or mats can be inserted to support the half-shells 3, 4 , so that, as it were, an additional supporting surface layer results in the form of a laminate.

In die umlaufende Nut 17 kann auch, wie aus Fig. 2 ersichtlich, ein Schlauch 18 aus elastomerem Material eingelegt sein. Weiter können die Kernhälften mit längsverlaufenden Schlitzen 19, 20 und 21, 22 versehen sein, in die sogenannte Stringer 23, 24 eingeklebt sind, die dem Segelbrett eine zusätzliche Biegesteifigkeit um seine Querachse verleihen. As can be seen in FIG. 2, a hose 18 made of elastomeric material can also be inserted into the circumferential groove 17 . Furthermore, the core halves can be provided with longitudinal slots 19, 20 and 21, 22 , into which so-called stringers 23, 24 are glued, which give the sail board additional flexural rigidity about its transverse axis.

Der Schaumkunststoffkern besteht gemäß dem Hauptmerkmal der Erfindung also aus zwei in seiner horizontalen Mittelebene längs getrennten Kernhälften, die mit im zusammengesetzten Zustand gegenüberliegenden, miteinander fluchtenden, röhrenförmigen Ausnehmungen versehen sind, welche durch Stege voneinander getrennt sind, die deckungsgleich auf­ einander zu liegen kommen. Die Stege weisen vorzugsweise Zapfen und Ausnehmungen und/oder Nut und Feder auf, die gegeneinander weisen. Die Höhlungen sind derart gestaltet, daß sie im Zuge der Herstellung flüssigen Klebstoff aufnehmen können, wobei die Hohlräume jeweils in einem derartigen Abstand vor den Oberflächen der Kernhälften enden, daß diese von diesen durch eine ausreichende Tritt- bzw. Stoßfestig­ keit gewährleistende gewölbeartige Boden-Deckenformation getrennt sind. Die Hohlräume sind in sich geschützt und gegeneinander herme­ tisch abgeschlossen, da sie sich im Innern der verklebten Schaum­ kernhälften befinden.The foam plastic core is according to the main feature of the invention that is, two longitudinally separated in its horizontal median plane Core halves, which, when assembled, are opposite, aligned, tubular recesses are provided, which are separated from each other by bridges that are congruent come to rest on each other. The webs preferably have pins and Recesses and / or tongue and groove, which face each other. The cavities are designed so that they are in the course of manufacture can absorb liquid adhesive, the cavities each end at such a distance in front of the surfaces of the core halves, that these of these by sufficient kick or shock resistance vault-like floor-ceiling formation ensuring separate are. The cavities are protected in themselves and are mutually exclusive table complete as it is inside the glued foam half of the core.
