Date Sep. 24, 1987.The present invention provides a surfboard which includes, in the lower aft region, a vertically narrow flexible tongue, the bending range of which is restricted by an elastic device, and, in the upper aft region, a covering material. Two supports are arranged one behind the other in the surfboard's longitudinal direction. A rear support is secured to the tongue, and a forward support is located in the region of the forward end of the tongue or in front of the tongue. A stringer is provided for elastically connecting the front and rear supports. The surfboard provides a simple and space-saving design.

Description

Surfbrett surfboard
Die Erfindung bezieht sich auf ein Surfbrett, dessen Heckbereich unten eine in vertikaler Richtung schmale, biegsame Zunge, deren Aufbiegungsbereich durch eine elastische Vorrichtung begrenzt ist, und oben Abdeckmaterial aufweist.The invention relates to a surfboard, the rear area of which has a flexible tongue which is narrow in the vertical direction at the bottom, the bending area of which is limited by an elastic device, and which has covering material at the top.
Ein solches Brett hat die Eigenschaft, daß es bei Geradeausfahrt, bei der das Gewicht des Surfers aufgrund der schrägen Pahrweise zum Teil von seinen Armen aufgenommen wird, seine von Hause aus vorgegebene Form (weitgehend) beibehält, daß aber bei Kurvenfahrt, bei der der Surfer mehr Druck auf das Brett übertragen kann, sich das Heck des Brettes aufbiegt, was die Kurvenfahrt erleichtert.Such a board has the property that when driving straight ahead, in which the weight of the surfer is partly absorbed by his arms due to the inclined driving style, it retains (largely) the shape that it has inherited from the home, but when cornering, when the surfer can transfer more pressure to the board, the rear of the board bends, which makes cornering easier.
Bei einem bekannten Brett dieser Art (US-PS 3 9o2 2o7) ist als elastische Vorrichtung ein zweiarmiger Hebel mit brettfestem Drehpunkt vorgesehen, dessen einer Arm sich an der Zunge und dessen anderer Arm sich an einem elastischen, in vertikaler Richtung wirkenden Anschlagelement abstützt. Diese Vorrichtung ist relativ kompliziert und in vertikaler Richtung raumaufwendig.In a known board of this type (US-PS 3 9o2 2o7) a two-armed lever with a board-fixed pivot point is provided as an elastic device, one arm of which is supported on the tongue and the other arm is supported on an elastic stop element acting in the vertical direction. This device is relatively complicated and space-consuming in the vertical direction.
Der Erfindung liegt die Aufgabe zugrunde, das eingangs definierte Surfbrett derart auszubilden, daß es einfacher als das bekannte und in vertikaler Richtung weniger raumbeanspruchend ausgebildet ist.The invention has for its object to design the surfboard defined in such a way that it is simpler than the known and less space-consuming in the vertical direction.
Diese Aufgabe wird erfindungsgemäß gelöst durch zwei in Surfbrettlängsrichtung hintereinander angeordnete Stützen, von denen die hintere an der Zunge befestigt ist und die vordere im Bereich des vorderen Zungenendes oder davor sitzt, und einen in Brettlängsrichtung in sich elastische oder elastisch abgefederten Stringer zwischen den beiden Stützen.This object is achieved according to the invention by two supports arranged one behind the other in the longitudinal direction of the surfboard, of which the rear is attached to the tongue and the front sits in the area of the front end of the tongue or in front of it, and a stringer which is elastic or resilient in the longitudinal direction of the board between the two supports.
Die erfindungsgemäße Ausbildung zeichnet sich gegenüber der bekannten durch größere Einfachheit und geringeren Raumbedarf in vertikaler Richtung aus.The design according to the invention is distinguished from the known by greater simplicity and smaller space requirements in the vertical direction.
Eine Weiterentwicklung der Erfindung besteht darin, daß der Raum oberhalb der Zunge von hochelastischem Material ausgefüllt ist. Das bringt u.a. den Vorteil mit sich, daß die Füße des Surfers abgefedert stehen, was als angenehm empfunden wird.A further development of the invention is that the space above the tongue is filled with highly elastic material. That brings among other things the advantage that the surfer's feet are cushioned, which is perceived as pleasant.
Weiterhin wird vorgeschlagen, daß sich unterhalb des Stringers zungenfeste oder stringerfeste Sockel befinden, die in geringem Abstand von dem Stringer oder der Zunge enden. Auf diese Weise wird erreicht, daß eine Verbiegung der Zunge nach unten begrenzt ist.Furthermore, it is proposed that tongue-fixed or stringer-fixed bases are located below the stringer, which end at a short distance from the stringer or the tongue. In this way it is achieved that a downward bending of the tongue is limited.
Ferner ist es zweckmäßig, wenn sich zwischen der Zunge und dem Stringer Federn befinden, die vorzugsweise hinsichtlich der Federcharakteristik verstellbar sind. Diese Maßnahme dient der Beeinflussung der Biegelinie der Zunge bei Verbiegung derselben nach oben oder unten.Furthermore, it is expedient if there are springs between the tongue and the stringer, which are preferably adjustable with regard to the spring characteristic. This measure serves to influence the bending line of the tongue when the tongue is bent upwards or downwards.
Weitere Einzelheiten der Erfindung ergeben sich aus der Zeichnung.Further details of the invention emerge from the drawing.

Die Figuren 1 und 2 zeigen das hintere Ende eines erfindungsgemäßen Surfbrettes. Dieses besteht aus einer Zunge 1, zwei Stützen 2 und 3, einem zwischen den Stützen 2 und 3 eingespannten Stringer 4, einem elastischen Puffer 5 zwischen dem Stringer 4 und der Stütze 2, hochelastisch Ausfüllmaterial 6 oberhalb der Zunge 1 (in Fig. 2 ist das Material weggelassen) und Schlaufen 7 und 8 zum Halte der Füße des Surfers. Der Stringer 4 ist über einen Bolzen 9, der in Schlitze lo zweier stützenfester Laschen 11 steckt, gegenüber der Stütze 2 längsverschieblich gelagert. Er stützt sich über eine Platte 12 an dem Gummipuffer 5 ab, der seinerseits mit seinem vorderen Ende der Stütze 2 anliegt. Der Gummipuffer 5 bewirkt also eine elastische Lagerung, des Stringers 4 in Brettlängsrichtung.Figures 1 and 2 show the rear end of a surfboard according to the invention. This consists of a tongue 1, two supports 2 and 3, a stringer 4 clamped between the supports 2 and 3, an elastic buffer 5 between the stringer 4 and the support 2, highly elastic filler material 6 above the tongue 1 (in FIG. 2) the material omitted) and loops 7 and 8 for holding the surfer's feet. The stringer 4 is mounted in a longitudinally displaceable manner with respect to the support 2 by means of a bolt 9 which is inserted into slots 10 of two brackets 11 fixed to the support. It is supported by a plate 12 on the rubber buffer 5, which in turn rests with the front end of the support 2. The rubber buffer 5 thus causes an elastic mounting of the stringer 4 in the longitudinal direction of the board.
Figur 3 zeigt diese Lagerung im einzelnen. Der Gummipuffer 3 wird von einer Schraube 13 durchzogen. Auf der Schraube 13 sitzt eine Mutter 14. Der Gummipuffer 5 hat im unbelasteten Zustand eine bikonvexe Form. Die beiden konvexen Flächen können mittels der Schraube 13 und der Mutter 14 zusammengedrückt werden. Auf diese Weise ist es möglich, die Elastizität des Gummipuffers 3 zu verstellen. Die Figuren 4 und 5 zeigen das Heck einer anderen Ausführungsart. Diese besteht aus einer Zunge 1, einem Lagerarm 15, zwei Stringern 4, zwei elastischen Puffern 16 zungenfesten Sockeln 17, Federringen 18 zwischen den Stringern 4 und der Zunge 1 und Querstreben 19 zwischen den Stringern 4. Der Verband, bestehend aus dem Stringer 4 und dem Puffer 16, ist jeweils zwischen dem Lagerarm 15 und einem Stützpunkt 2o eingespannt. Letzterer befindet sich in einer Brettfläche, die vertikal oder schräg verläuft. Die Federn 18 sind über Schrauben 21 mit dem Stringer verbunden. Diese Schrauben ermöglichen es, den Abstand zwischen den Federn 18 und den Stringern 4 zu verändern und auf diese Weise die Federkraft der Federn 18 zu verstellen. Zwei hintereinander angeordnete, nicht dargestellte Fußschlaufen befinden sich zwischen dem Lagerarm 15 und der benachbarten Querstrebe 19 einerseits und den beiden Querstreben 19 andererseits. Der Raum oberhalb der Zunge 1 ist mit hochelastischem Material ausgefüllt.Figure 3 shows this storage in detail. The rubber buffer 3 is pulled through by a screw 13. A nut 14 sits on the screw 13. The rubber buffer 5 has a biconvex shape in the unloaded state. The two convex surfaces can be pressed together by means of the screw 13 and the nut 14. In this way it is possible to adjust the elasticity of the rubber buffer 3. Figures 4 and 5 show the rear of another embodiment. This consists of a tongue 1, a bearing arm 15, two stringers 4, two elastic buffers 16 tongue-fixed bases 17, spring washers 18 between the stringers 4 and the tongue 1 and cross struts 19 between the stringers 4. The association, consisting of the stringer 4 and the buffer 16, is clamped between the bearing arm 15 and a base 20. The latter is located in a board surface that runs vertically or at an angle. The springs 18 are connected to the stringer by screws 21. These screws make it possible to change the distance between the springs 18 and the stringers 4 and in this way to adjust the spring force of the springs 18. Two successive foot straps, not shown, are located between the bearing arm 15 and the adjacent cross strut 19 on the one hand and the two cross struts 19 on the other hand. The space above tongue 1 is filled with highly elastic material.
Ein Puffer 16 kann hinsichtlich seiner Elastizität einstellbar sein. Er kann andererseits auch fehlen. Dann sollte allerdings der Stringer 4 in sich elastisch sein. Auch ist es denkbar, daß zwischen dem Stringer 4 und dem Lager 2o bzw. dem Puffer 16 in der Grundstellung des Brettes ein Abstand herrscht, dergestalt, daß in einem Anfangs- Biegebereich der Zunge die Biege- und Torsionskräfte allein von der Zunge aufgebracht werden und Stringer und Anschlagfläche als Biegebegrenzung dienen.A buffer 16 can be adjustable in terms of its elasticity. On the other hand, it can also be missing. Then, however, the stringer 4 should be elastic in itself. It is also conceivable that there is a distance between the stringer 4 and the bearing 20 or the buffer 16 in the basic position of the board, in such a way that the bending and torsional forces are applied only by the tongue in an initial bending region of the tongue and The stringer and stop surface serve as a limitation of the bending.
Die Figuren 6 und 7 zeigen eine Ausführungsform, die dadurch gekennzeichnet ist, daß ein Heck entsprechend der erfindungsgemäßen Ausbildung nachträglich an ein Surfbrett herköamlicher Art, bei dem das Heck abgeschnitten worden ist, angesetzt worden ist. Die Zunge 1 steht nach vorn weiter über als der übrige Teil des Hecks. Ihr überstehender Teil ist mittels Dübel 22 an dem restlichen Teil des Surfbrettes befestigt. Außerdem ragen aus diesem restlichen Teil nach hinten Laschen 23, an denen die Stringer 4 befestigt sind. Mit 17 sind wieder zungenfeste Sockel, mit 18 einstellbare Federn (in diesem Falle Schraubenfedern), mit 19 eine Querstrebe und mit 8 eine Fußschlaufe bezeichnet. Die hintere Fläche des restlichen Teils des Surfbrettes ist durch eine Schicht 24 aus hochfestem Kunststoff versehen.Figures 6 and 7 show an embodiment, which is characterized in that a rear according to the inventive design retrofitted to a surfboard conventional type, in which the rear has been cut off, has been attached. The tongue 1 protrudes further forward than the rest of the tail. Its protruding part is attached to the remaining part of the surfboard by means of dowels 22. In addition, tabs 23 to which the stringers 4 are fastened protrude from this remaining part. 17 are again tongue-proof bases, 18 adjustable springs (in this case coil springs), 19 a cross strut and 8 a foot strap. The rear surface of the remaining part of the surfboard is provided with a layer 24 of high-strength plastic.
Die Stringer 4 sind über Gummipuffer 25 mit den Laschen 23 verbunden. Diese Puffer haben die Form gebogener Quader. Sie können mittels Schrauben 26 derart zusammengedrückt werden, daß sie sich einem ungebogenen Quader annähern. Auf diese Weise ist die Elastizität der Gummipuffer erhöhbar. The stringers 4 are connected to the tabs 23 via rubber buffers 25. These buffers have the shape of curved cuboids. They can be pressed together using screws 26 in such a way that they approach an unbent cuboid. In this way, the elasticity of the rubber buffers can be increased.
