Abstract
Description
Die Erfindung betrifft einen Hockeyschläger mit einem Kopf, einem Griff und einem diese verbindenden Schaft, wobei der Hockeyschläger mindestens teilweise aus einem faserverstärk ten Kunststoff besteht. Die Erfindung betrifft weiter ein Verfahren zum Herstellen eines Hockeyschlägers.The invention relates to a hockey stick with a head, a handle and a shaft connecting them, the Hockey stick at least partially made of fiber reinforcement there is plastic. The invention further relates to a Method of making a hockey stick.
Hockeyschläger wurden ursprünglich nur aus Holz gefertigt. Aus dieser Herstellung aus Holz ergibt sich der Rechteckquer schnitt, den der Hockeyschläger im Bereich des Kopfes, des Schaftes und des Griffes aufweist. Hieraus ergibt sich auch, daß ein Hockeyschläger über seiner gesamten Länge aus einem einzigen Werkstoff besteht. Dies gilt sowohl für aus Holz ge fertigte als auch für die heute aus Kunststoff gefertigten Hockeyschläger.Hockey sticks were originally made only from wood. The rectangular cross results from this production from wood cut the hockey stick in the area of the head, the Has shaft and the handle. It also follows that that a hockey stick over its entire length from one single material. This applies to both made of wood manufactured as well as for those now made of plastic Hockey stick.
Nachdem Hockeyschläger ursprünglich nur aus Holz gefertigt wurden, ging man dann dazu über, dieses Holz an seiner Ober fläche mit Fasern und Kunstharz zu verstärken. Anschließend baute man Hockeyschläger mit einem Kern aus Schaumstoff und einer Ummantelung aus Fasern und Kunstharz, die mit der Hand naß auflaminiert wurden. Ein auf diese Weise gefertigter Hoc keyschläger bestand zu 50% aus Schaumstoff und zu 50% aus Fasern und Kunstharz. In einer weiteren Entwicklungsstufe wurden der aus Schaumstoff bestehende Kern und trockene Fa sern in eine Spritzgußform eingelegt. Ein solches Herstel lungsverfahren ist unter dem Namen Transfer Injection Mol ding bekannt. Die Herstellung der Hockeyschläger hat damit den gleichen Weg wie die Herstellung anderer Gegenstände durchlaufen. Ursprünglich wurden diese auch nur aus dem Na turprodukt Holz hergestellt, während sie heute ausschließ lich aus Kunststoffen hergestellt werden.After hockey sticks were originally made only from wood then you went over to this wood on your top reinforce the surface with fibers and synthetic resin. Subsequently you built hockey sticks with a core of foam and a covering of fibers and synthetic resin, which is hand-made were laminated wet. A hoc made in this way keyschläger consisted of 50% foam and 50% Fibers and synthetic resin. In a further stage of development the foam core and dry Fa serially placed in an injection mold. Such a manufacturer is called Transfer Injection Mol thing known. The production of the hockey stick has it the same way as making other items run through. Originally, these were only from the na wood product, while it excludes today Lich made of plastics.
Die Erfindung setzt diesen Weg fort. Ihr liegt die Aufgabe zugrunde, einen Hockeyschläger ausschließlich nach dem neue sten Stand der Technik und vollständig frei von den bekann ten Herstellungsverfahren zu fertigen. Dabei soll auch an die Wünsche des Hockeyspielers gedacht werden. Schließlich soll der Hockeyschläger seine herkömmliche Form, das heißt seinen Rechteckquerschnitt, beibehalten, obwohl weder die Fe stigkeit noch das Spiel mit dem Hockeyschläger diese Form verlangt.The invention continues on this path. You have the task based on a hockey stick exclusively after the new state of the art and completely free of known manufacturing process. It is also said to the wishes of the hockey player are thought of. After all the hockey stick should have its conventional shape, that is its rectangular cross section, although neither the Fe still playing with the hockey stick this shape demands.
Bei einem Hockeyschläger der eingangs genannten Gattung wird diese Aufgabe nach der Erfindung dadurch gelöst, daß Kopf und Schaft beide aus zwei zueinander parallel verlaufenden Hohlprofilen bestehen und beide Hohlprofile eine gemeinsame Mittelwand aufweisen und aus faserverstärktem Kunststoff be stehen. Kopf und Schaft bestehen dabei zweckmäßig beide aus Prepeg. Unter Prepeg versteht man ein im Handel erhältliches Tape, ein unidirektionales Band, das aus mit Kunstharz vor imprägnierten Fasern besteht. Ein aus Prepeg gefertigter Hockeyschläger hat ein so großes Widerstandmoment und eine so hohe Festigkeit, daß er zum Erreichen seiner Sollfestig keit nicht massiv sein muß. Deshalb besteht der erfindungsge mäße Hockeyschläger aus zwei zueinander parallelen Hohlprofi len, deren aneinander anstoßende Wände zu einer gemeinsamen Mittelwand verschmolzen sind. Diese beiden parallel zueinan der verlaufenden Hohlprofile ergeben einmal die gewünschte Sollfestigkeit und führen zum anderen zu dem gewünschten Rechteckquerschnitt.With a hockey stick of the type mentioned at the beginning solved this problem according to the invention in that head and shaft both from two parallel to each other Hollow profiles exist and both hollow profiles have a common one Have middle wall and be made of fiber-reinforced plastic stand. Both head and shaft expediently consist of Prepeg. Prepeg means a commercially available one Tape, a unidirectional tape that is made with synthetic resin impregnated fibers. A made from prepeg Hockey stick has such a high moment of resistance and one so high strength that it reaches its target strength need not be massive. Therefore, there is the fiction moderate hockey stick made of two parallel hollow professionals len, the abutting walls to a common Middle wall are fused. These two in parallel of the running hollow profiles result in the desired one Target strength and lead to the desired one Rectangular cross section.
Die Innenwände beider Hohlprofile bestehen zweckmäßig aus ei nem Schlauch. Dieser besteht vorzugsweise aus einem Polyamid oder einem Silikon. In einer zweckmäßigen Ausführungsform ist der Griff in einem Arbeitsgang und einstückig mit dem Kopf und dem Schaft ausgebildet.The inner walls of both hollow profiles are suitably made of egg hose. This preferably consists of a polyamide or a silicone. In an expedient embodiment is the handle in one step and in one piece with the Head and shaft trained.
Die bekannten, durchgehend aus Kunststoff bestehenden Hockey schläger sind verhältnismäßig steif. Der beim Auftreffen des Kopfes auf den Ball entstehende Stoß überträgt sich damit bis in den Griff und wandert von dort in die Hand und das Handgelenk des Spielers. Auf die Dauer wirkt dies belastend und schädigt das Handgelenk. Zum Vermeiden dieser Belastung und Schädigung des Handgelenks sieht die Erfindung in einer weiteren zweckmäßigen Ausgestaltung vor, daß der Griff aus einem thermoplastischen Kunststoff besteht und auf das ihm zugewandte Ende des Schaftes teilweise aufgeschoben und auf diesem gehalten ist. Thermoplastische Kunststoffe sind wei cher, elastisch und federnd. Ein erfindungsgemäßer Griff fängt damit die Schläge ab und hält sie vom Handgelenk des Spielers fern. Der auf das Ende des Schaftes aufgeschobene Griff kann auf den Schaft aufgeklebt oder ohne Klebung im Preßsitz auf diesem gehalten sein.The well-known hockey made entirely of plastic Clubs are relatively stiff. The one when the The impact of the head on the ball is transferred up to the handle and from there it goes into your hand and that Wrist of the player. In the long run, this is stressful and damages the wrist. To avoid this burden and wrist damage sees the invention in one further expedient embodiment before that the handle a thermoplastic and insists on it facing end of the shaft partially pushed on and on this is held. Thermoplastic materials are white cher, elastic and springy. A handle according to the invention catches the blows and holds them from the wrist of the Player away. The one pushed onto the end of the shaft Handle can be glued to the shaft or without gluing in the Press fit to be held on this.
Das erfindungsgemäße Verfahren zum Herstellen des vorstehend gekennzeichneten Hockeyschlägers zeichnet sich dadurch aus, daß ein Schlauch von etwa der doppelten Länge von Schaft und Kopf in U-Form gelegt, der in U-Form liegende Schlauch mit Prepeg beschichtet und ummantelt, der mit Prepeg ummantelte Schlauch in eine Form gelegt, die Form geschlossen, der Schlauch anschließend aufgeblasen und die Form aufgeheizt wird. Dabei sollten die beiden offenen Enden des Schlauches in dem dem Griff zugewandten Ende des Schaftes zu liegen kom men. Beim ersten Beschichten und Ummanteln des Schlauches mit Prepeg wird die in der Form auf nehmbare Menge, Ausrich tung und Lage des Prepegs bei einem Prototyp bestimmt und für die folgende Produktion festgehalten. Damit muß man nur beim ersten Beschichten und Ummanteln durch mehrmaliges Ein legen des Rohlings in die Form ermitteln, wieviel Prepeg je desmal an welcher Stelle und in welcher Ausrichtung benötigt wird.The inventive method for producing the above marked hockey stick is characterized by that a tube of about twice the length of the shaft and U-shaped head, the U-shaped hose with Coated and coated prepeg, which coated with prepeg Hose placed in a mold, the mold closed, the Then inflate the tube and heat the mold becomes. The two open ends of the hose should do the same to lie in the end of the shaft facing the handle men. The first time you coat and coat the hose With prepeg, the amount that can be taken in the mold is aligned determination and location of the prepeg in a prototype and captured for the next production. You just have to with the first coating and coating by repeated one place the blank in the form determine how much prepeg ever at what point and in what orientation becomes.
Am Beispiel der in der Zeichnung gezeigten Ausführungsform wird der erfindungsgemäße Hockeyschläger nun weiter beschrie ben. In der Zeichnung ist:Using the example of the embodiment shown in the drawing the hockey stick according to the invention is now further described ben. In the drawing is:

Die Figuren zeigen den Hockeyschläger 12 mit seinem Griff 14, seinem Schaft 16 und dem Kopf 18. Der Griff 14 ist auf das ihm zugewandet und in den Fig. 1 und 2 oben liegende Ende 20 des Schaftes 16 aufgeschoben. Dieser Griff 14 be steht aus einem thermoplastischen Kunststoff. Gemäß den Dar stellungen in den Fig. 3 und 4 hat er Kreisquerschnitt. The figures show the hockey stick 12 with its handle 14 , its shaft 16 and the head 18 . The handle 14 faces the end 20 of the shaft 16 which is at the top in FIGS. 1 and 2. This handle 14 be made of a thermoplastic material. According to the Dar positions in FIGS. 3 and 4, it has a circular cross section.
In etwa Kreisquerschnitt hat der Schaft 16 auch noch in der Schnittebene C-C. In den weiteren Schnittebenen D-D bis G-G weisen der Schaft 16 und der Kopf 18 den genannten Rechteckquerschnitt auf. In diesen Bereichen werden der Schaft 16 und der Kopf 18 durch die beiden Hohlprofile 22 und 24 mit der gemeinsamen Mittelwand 26 gebildet. Die Innen wände der beiden Hohlprofile 22 und 24 werden durch den Schlauch 28 gebildet.The shaft 16 also has an approximately circular cross section in the sectional plane CC. In the further sectional planes DD to GG, the shaft 16 and the head 18 have the said rectangular cross section. In these areas, the shaft 16 and the head 18 are formed by the two hollow profiles 22 and 24 with the common central wall 26 . The inner walls of the two hollow profiles 22 and 24 are formed by the hose 28 .
Zur Herstellung des Hockeyschlägers wird als erstes der noch gerade Schlauch 28 von Hand mit Prepeg belegt und ummantelt. Anschließend wird der Schlauch 28 zu einem U gelegt und im Bereich des Kopfes abgebogen. Der in Form eines U liegende Schlauch bildet einen Doppelschlauch. Beim ersten Belegen und Ummanteln wurde festgehalten, welche Länge oder welche Menge Prepeg benötigt wird. Diese Zahlen werden festgehal ten. Mit der beim Bau des Protops bestimmten Anzahl, Ausrich tung und Position der Prepeglagen wird jeder weitere Doppel schlauch vervollständigt. Nachdem sämtliche Stücke und Strei fen des Prepeg nach Konstruktionsplan aufgelegt sind, wird der mit Prepeg belegte Doppelschlauch in eine Negativform des Hockeyschlägers gelegt. Diese Form wird verschlossen und geheizt. Dabei wird der Schlauch 28 aufgeblasen. Dabei drückt er das unter der Einwirkung der Hitze zähflüssig ge wordene Prepeg gegen die Innenwände der Form. Nach Ablauf ei ner bestimmten, vom Harztyp und der Höhe der Temperatur ab hängigen Zeit ist das Harz ausgehärtet. Der fertige Hockey schläger 12 kann der Form entnommen werden. Gegebenenfalls muß seine Oberfläche noch bearbeitet und Grat entfernt wer den. Sofern es sich um die Ausführungsform handelt, bei der der Griff 14 getrennt aus einem thermoplastischen Werkstoff hergestellt wurde, wird dieser in einem letzten Arbeitsgang auf das Ende 20 des Schaftes 16 aufgeschoben. Dabei werden die Abmessungen entweder so getroffen, daß der Griff 14 im Preßsitz auf dem Ende 20 sitzt, oder der Griff 14 wird aufge klebt. To manufacture the hockey stick, the still straight tube 28 is first covered with prepeg by hand and coated. The tube 28 is then laid to a U and bent in the area of the head. The U-shaped hose forms a double hose. When first covering and sheathing, it was recorded what length or how much prepeg is required. These numbers are recorded. With the number, orientation and position of the prepreg layers determined during the construction of the protop, each additional double hose is completed. After all pieces and strips of the prepeg are placed according to the construction plan, the double tube covered with prepeg is placed in a negative form of the hockey stick. This mold is closed and heated. The hose 28 is inflated. He presses the prepeg, which has become viscous under the influence of heat, against the inner walls of the mold. After a certain time, depending on the type of resin and the level of the temperature, the resin has hardened. The finished hockey stick 12 can be removed from the form. If necessary, its surface must still be machined and burr removed. If it is the embodiment in which the handle 14 was made separately from a thermoplastic material, it is pushed onto the end 20 of the shaft 16 in a last working step. The dimensions are either made so that the handle 14 sits in a press fit on the end 20 , or the handle 14 is glued up.
Die Schnitte der Fig. 3 bis 9 zeigen den Querschnitt des Hockeyschlägers 12 ausgehend vom Griff 14 bis zum Kopf 18. Auf diesem Weg geht der Querschnitt von einer Kreis- in eine Rechteckform über. Gleichzeitig erkennt man die großen Hohl profile 22 und 24. Die von diesen umschlossenen Lufträume führen zu dem geringen Gewicht des erfindungsgemäßen Hockey schlägers 12. Die Außenwände und die gemeinsame Mittelwand 26 verleihen ihm eine wabenförmige und damit stabile Struk tur. Fig. 10 zeigt in vergrößerter Darstellung und nicht maß stäblich den Schlauch 28. Dieser bildet, wie schon in Fig. 7 angedeutet ist, die Innenwand der beiden Hohlprofile 22 und 24.The sections of FIGS. 3 to 9 show the cross section of the hockey stick 12, starting from the handle 14 to the head 18. In this way, the cross section changes from a circular to a rectangular shape. At the same time you can see the large hollow profiles 22 and 24 . The air spaces enclosed by these lead to the low weight of the hockey stick 12 according to the invention. The outer walls and the common middle wall 26 give it a honeycomb-shaped and thus stable structure. Fig. 10 shows an enlarged illustration and not measured stäblich hose 28. As already indicated in FIG. 7, this forms the inner wall of the two hollow profiles 22 and 24 .
