Description

HockeyschlägerHockey stick
Die Erfindung betrifft einen Hockeyschläger nach dem Oberbegriff des Patentanspruches 1.The invention relates to a hockey stick according to the preamble of claim 1.
Unter den Begriff Hockeyschläger fallen sowohl Eishockeyschläger als auch Streethockeyschläger od. dgl.The term hockey sticks include both ice hockey sticks and street hockey sticks or the like.
Hockeyschläger werden üblicherweise aus Mehrschichtholzaufbauten hergestellt, wobei in den unteren Preisklassen ein reiner Holzstock aus schichtverleimten Furnieren Anwendung finden. Für höhere Anforderungen werden an den beanspruchteren Zonen des Holzstocks glasfaserverstärkte Kunststoffe bzw. kohlefaserverstärkte Kunststoffe oder Kombinationen davon eingesetzt, um die Widerstandsfähigkeit zu erhöhen. Auch die Schaufel des Hockeyschlägers ist üblicherweise aus einem Holzkern, bestehend aus Schichthölzern oder aus Massivholz und beidseitigen Begurtungen von glasfaser- oder kohlefaserverstärkten Kunststoffen aufgebaut. Diese Konstruktionen sind zwar relativ billig herzustellen, weisen aber ein relativ hohes Eigengewicht auf, welches sich negativ auf die Spieleigenschaften auswirkt.Hockey sticks are usually made from multi-ply wood structures, with a pure wooden stick made of layer-glued veneers being used in the lower price ranges. For higher requirements, glass fiber reinforced plastics or carbon fiber reinforced plastics or combinations thereof are used in the more stressed areas of the wooden stick in order to increase the resistance. The blade of the hockey stick is usually made up of a wooden core consisting of laminated wood or solid wood and straps on both sides made of glass fiber or carbon fiber reinforced plastics. Although these constructions are relatively inexpensive to manufacture, they have a relatively high weight, which has a negative effect on the playing properties.
Zur Reduktion des Gewichts der Hockeyschläger wurden Hohlprofile aus Aluminium mit glasfaser- oder kohlefaserverstärkten Kunststoffüberzügen eingesetzt. Solche Konstruktionen sind allerdings relativ kompliziert herzustellen und somit teuer.In order to reduce the weight of the hockey sticks, hollow profiles made of aluminum with glass fiber or carbon fiber reinforced plastic covers were used. However, such constructions are relatively complicated to manufacture and therefore expensive.
Aufgabe der vorliegenden Erfindung ist daher die Schaffung eines Hockeyschlägers, der die Eigenschaften einer billigen Herstellung und eines niedrigen Gewichts idealerweise verbindet, wobei die Nachteile der bekannten Hockeyschläger reduziert bzw. vermieden werden.The object of the present invention is therefore to provide a hockey stick which ideally combines the properties of cheap manufacture and low weight, the disadvantages of the known hockey sticks being reduced or avoided.
Gelöst wird diese Aufgabe durch die Maßnahme nach dem kennzeichnenden Teil des Patentanspruches 1. Diese Leichtbaukerne weisen eine sehr hohe Festigkeit und extrem niedriges Gewicht auf und sind außerdem relativ günstig herzustellen.This object is achieved by the measure according to the characterizing part of patent claim 1. These lightweight cores have a very high strength and extremely low weight and are also relatively inexpensive to manufacture.
Beim Einbau der Leichtbaukerne in der Schaufel sind nach einem weiteren Merkmal der Erfindung die Öffnungen der Waben zur Schlagfläche der Schaufel hin gerichtet. Gemäß einem Erfindungsmerkmal sind zwischen Regionen der Leichtbaukerne dünne Holzfurniere od. dgl. oder seitliche Decklaminate angeordnet. Durch diese wird die Festigkeit weiter erhöht, ohne daß sich das Gewicht wesentlich erhöht.When installing the lightweight cores in the blade, according to a further feature of the invention, the openings of the honeycomb are directed towards the face of the blade. According to one feature of the invention, thin wood veneers or the like or lateral cover laminates are arranged between regions of the lightweight cores. This further increases the strength without significantly increasing the weight.
Vorteilhafterweise ist der Hockeyschläger außen mit glasfaser- oder kohlestoffaserverstärkten Kunststoffen überzogen. Dadurch wird die Widerstandsfähigkeit weiter erhöht.Advantageously, the hockey stick is coated on the outside with glass fiber or carbon fiber reinforced plastics. This further increases the resilience.
Gemäß einem weiteren Erfindungsmerkmal ist vorgesehen, daß im Bereich des Konus, das ist jene Stelle, die an die schaufei des Schägers anschließt, Einlagen aus Massivholz eingesetzt sind. Die Einlage kann als ein- oder mehrteiliger Einsatz ausgebildet sein. Durch diese Einsätze von Massivholzeinlagen können die Kräfte besser übertragen werden.According to a further feature of the invention, it is provided that in the region of the cone, that is the point that adjoins the shovel of the racket, inserts made of solid wood are used. The insert can be designed as a single or multi-part insert. The use of solid wood inlays enables the forces to be transferred better.
Diese und weitere Merkmale der Erfindung werden anhand der beigefügten Zeichnungen, welche Au^führungsbeispiele der Erfindung zeigen, näher erläutert.These and other features of the invention will be explained in more detail with reference to the accompanying drawings, which show exemplary embodiments of the invention.

Fig. 8 eine Ausführungsvariante des Schaftes des Schlägers.Fig. 8 shows a variant of the shaft of the racket.
Der Hockeyschläger besitzt einen Schaft 1 sowie eine Schaufel 2, welche unter einem Winkel, vorzugsweise zwischen 90° und 140° Grad, vom Schaft 1 absteht. Sowohl der Schaft 1 als auch die Schaufel 2 besitzt als wesentlichen Bestandteil einen Leichtbaukern 13 auf Basis von Waben, insbesondere aus Kunststoff- oder Papierstreifen, die mit Harzsystemen beschichtet sind. Selbstverständlich besteht auch die Möglichkeit, andere leichte Materialien zu verwenden. Bei der Ausführungsform des Hockeyschlägers gemäß Fig. 3 besitzt der Schaft 1 an seinem schaufelseitigen Ende eine Holzeinlage 3. Wie Fig. 2 zeigt, bildet die Holzeinlage 3 ein konisch verlaufendes Anschlußstück zwischen Schaft 1 und Schaufel 2. Diese Holzeinlage 3 kann ein- oder mehrschichtig ausgebildet sein, wobei die Schichten im wesentlichen parallel zur Schlagfläche gelegen sind. Es besteht aber auch die Möglichkeit, eine anders orientierte Schichtung vorzunehmen. Bei der gegenständlichen Ausführungsform des Hockeyschlägers kann zumindest im Übergangsteil zwischen Leichtbaukern 13 des Schaftes 1 und Leichtbaukern 13 der Schaufel 2 auf eine seitliche Abdeckung des Hockeyschlägers verzichtet werden.The hockey stick has a shaft 1 and a blade 2 which protrudes from the shaft 1 at an angle, preferably between 90 ° and 140 ° degrees. Both the shaft 1 and the blade 2 have, as an essential component, a lightweight core 13 based on honeycombs, in particular made of plastic or paper strips, which are coated with resin systems. Of course there is also the possibility to add other light materials use. In the embodiment of the hockey stick according to FIG. 3, the shaft 1 has a wooden insert 3 at its blade-side end. As FIG. 2 shows, the wooden insert 3 forms a conical connecting piece between the shaft 1 and the blade 2. This wooden insert 3 can have one or more layers be formed, the layers being substantially parallel to the face. However, it is also possible to do a differently oriented stratification. In the present embodiment of the hockey stick, at least in the transition part between the lightweight core 13 of the shaft 1 and the lightweight core 13 of the blade 2, there is no need for a side cover for the hockey stick.
Fig. 4 zeigt einen Abschnitt des Schaftes 1 des Hockeyschlägers in schaubildlicher Darstellung, wobei der Schaft 1 außenseitig einander gegenüberliegend jeweils ein Laminat 10 und im Anschluß daran eine Holzfurnierplatte 12 und zwischen den Holzfiirnierplatten 12 einen wabenförmig gestalteten Leichtbaukem 13 besitzt, welcher an seinen beiden Außenseiten durch je eine Holzfurnierplatte 12' abgedeckt ist. Der Aufbau des Leichtbaukernes entspricht dem Kern nach dem Schweizer Patent CH 666 410, wonach der Kern aus aufeinanderfolgenden Schichten besteht, von denen jede aus einem gewellten und daran anschließenden ebenen Papier- oder Kunststoffstreifen besteht, der imprägniert ist, und vorzugsweise eine Beschichtung aus Harz bzw. Harzsystem aufweist. Die gewellten Streifen können, wie dargestellt, um eine halbe Wellenlänge zueinander versetzt sein, wobei die Wellenstreifen mit den ebenen Streifen im Bereiche der Wellentäler bzw. Wellenberge mit den ebenen Streifen verklebt sein können. Vorzugsweise besitzt der Leichtbaukem 13 die gleiche Höhe wie die Holzfurnierplatte 12', sodaß beim Zusammenbau des Schaftes 1 durch die Holzfurnierplatten 12 kein Zusammendrücken bzw. Beschädigen oder Zerstören des Leichtbaukernes 13 stattfindet. Der Leichtbaukem 13 ist so eingebaut, daß die Öffnungen der Waben den Holzfurnierplatten 12 gegenüberliegen. Anstelle der Holzfurnierplatten 12, 12' können auch Laminate aus glasfaserverstärktem oder kohlestoffverstärktem Kunststoff (GFK/CFK-Laminate) ähnlich den Laminaten 10 verwendet werden.Fig. 4 shows a portion of the shaft 1 of the hockey stick in a diagrammatic representation, the shaft 1 on the outside opposite one another in each case a laminate 10 and then a wood veneer panel 12 and between the wood veneer panels 12 has a honeycomb-shaped lightweight construction 13, which on its two outer sides is covered by a wood veneer panel 12 '. The construction of the lightweight core corresponds to the core according to Swiss patent CH 666 410, according to which the core consists of successive layers, each of which consists of a corrugated and adjoining flat paper or plastic strip, which is impregnated, and preferably a coating of resin or Has resin system. As shown, the corrugated strips can be offset from one another by half a wavelength, wherein the wavy strips can be glued to the flat strips in the region of the wave troughs or wave crests to the flat strips. The lightweight core 13 preferably has the same height as the wooden veneer panel 12 ', so that when the shaft 1 is assembled by the wooden veneer panels 12, the lightweight core 13 is not compressed or damaged or destroyed. The lightweight core 13 is installed so that the openings of the honeycomb face the wood veneer panels 12. Instead of the wood veneer panels 12, 12 ', laminates made of glass fiber reinforced or carbon reinforced plastic (GRP / CFRP laminates) similar to the laminates 10 can also be used.
Bei der Variante nach Fig. 5 sind auch zwischen den Wabenschichten, d.h. zwischen den gewellten Streifen 13', Zwischenlagen 4 aus Holzfurnieren oder GFK/CFK-I.aminaten oder ähnlichem Material anstelle der beim vorangehenden Ausführungsbeispiel des Leichtbaukernes 13 vorhandenen ebenen Streifen 13" oder ergänzend zu diesen vorhanden. In letzterem Falle können die ebenen Streifen 13" ein- oder beidseitig der Zwischenlage 4 vorhanden sein.5 there are also between the honeycomb layers, ie between the corrugated strips 13 ', intermediate layers 4 made of wood veneer or GRP / CFRP laminates or similar material instead of the flat strips 13 "or 13 present in the previous embodiment of the lightweight core 13 in addition to these available. In the latter case, the flat strips 13 ″ can be present on one or both sides of the intermediate layer 4.
Als stirnseitige Abdeckung kann anstelle der Holzfurnierplatte 12 und des Laminats 10 eine einfache Abdeckung aus Holz, GFK/CFK-Laminaten und ähnlichem Material ein- oder beidseitig vorhanden sein.Instead of the wood veneer panel 12 and the laminate 10, a simple cover made of wood, GRP / CFRP laminates and similar material can be provided on one or both sides as the front cover.
Bei der Ausführungsform der Schaufel 2 nach den Fig. 6 und 7 der Zeichnung ist der Leichtbaukern 13 von einer Ummantelung 5 aus faserverstärktem Kunststoff umschlossen, wobei der Leichtbaukern 13 an den längsseitigen Enden innerhalb der Ummantelung 5 mit einer Einlage 6 bzw. 6' aus Holz oder Kunststoff versehen ist. Der Leichtbaukern 13 entspricht in seinem Aufbau dem Leichtbaukem 13 des Schaftes 1 nach Fig. 4 oder 5, wobei die Öffnungen der Waben schlagseitig bzw. an der gegenüberliegenden Seite gelegen sind.In the embodiment of the blade 2 according to FIGS. 6 and 7 of the drawing, the lightweight core 13 is enclosed by a sheathing 5 made of fiber-reinforced plastic, the lightweight core 13 at the longitudinal ends inside the sheathing 5 with an insert 6 or 6 'made of wood or plastic is provided. The construction of the lightweight core 13 corresponds to that of the lightweight core 13 of the shaft 1 according to FIG. 4 or 5, the openings of the honeycombs being located on the face side or on the opposite side.
Selbstverständlich können im Rahmen der Erfindung verschiedene konstruktive Änderungen vorgenommen werden. So besteht die Möglichkeit, den Leichtbaukern 13, wie Fig. 8 zeigt, unmittelbar oder unter Anordnung einer Zwischenlage mit einer Umhüllung 7 aus faserverstärktem Kunststoff, z.B. aus dichten Fasergeflechten, zu umschließen.
