Description

Die Erfindung betrifft einen Speer zur Verwendung in einer Halle, im wesentlichen bestehend aus einem Schaft, dessen Speerspitze stumpf ausgebildet ist und der in der Nähe seines Schwerpunktes einen Handgriff aufweist.The invention relates to a spear for use in a Halle, consisting essentially of a shaft, the Spearhead is blunt and close to his Focus has a handle.

Normale Speere für sportliche Zwecke weisen eine spitze Speerspitze auf, mit der sie in den Boden eindringen und stecken bleiben. Diese Speere sind daher nicht zur Verwendung in einer Halle geeignet.Normal spears for sporting purposes are pointed Spearhead with which they penetrate and stick into the ground stay. These spears are therefore not for use in suitable in a hall.

Unter einem Wettkampfspeer wird ein Speer verstanden, der dem Regelwerk der International Amateur Athletic Federation (IAAF), nämlich der Regel 193 der internationalen Wettkampfbestimmungen entspricht, denn nur solche Speere sind für nationale und internationale Wettkämpfe zugelassen.A competition spear is understood to mean a spear that International Amateur Athletic Federation regulations (IAAF), namely rule 193 of the international competition regulations corresponds, because only such spears are for national and international competitions.

In der Regel 193 "Speerwurf" der internationalen Wettkampfbestimmungen ist unter der Überschrift "Wettkampf" die Durchführung eines Speerwurfes beschrieben. Dabei bezieht sich der Punkt 1.a auf die Wurftechnik. Die Folgeüberschrift "Speer" bezieht sich in ihren Punkten 3 bis 9 auf die Konstruktion und Ausgestaltung eines Wettkampfspeeres. In den Punkten 3 bis 9 werden Wettkampfspeere mit konkreten technischen Merkmalen definiert. So kann man den Wettkampfbestimmungen insbesondere entnehmen, dass ein "Wettkampfspeer" vorgegebene Längen, einen vorgegebenen Durchmesser, ein vorgegebenes Gewicht und einen nach vorn verlagerten Schwerpunkt aufweist. Usually 193 "javelin throw" of international competition regulations is the implementation under the heading "Competition" described a javelin throw. The refers to Point 1.a on the throwing technique. The following heading "Speer" points 3 to 9 to the construction and design of a competition spear. In points 3 to 9 are competition spears with specific technical characteristics Are defined. So you can especially the competition regulations derive that a "competition javelin" given lengths, a given diameter, a given weight and has a shifted focus.

Weiterhin ist aus der WO 98/18400 ein Speer für Trainingszwecke bekannt, der eine stumpfe Speerspitze aufweist, die am vorderen Ende eines Schaftes angeordnet ist. An seinem hinteren Speerende weist der Schaft drei radial angeordnete Stabilisierungsflossen auf. Zwischen Speerspitze und Speerende ist am Schaft ein Handgriff, die sogenannte Wicklung, angeordnet. Dieser Trainingsspeer soll speziell dem Speerwurftraining von jugendlichen Trainierenden dienen. Seine einzelnen Komponenten sind aus einem Kunststoffmaterial gefertigt.Furthermore, from WO 98/18400 is a spear for training purposes known, which has a blunt spearhead that on front end of a shaft is arranged. At his rear The spear end of the shaft has three radially arranged stabilizing fins on. Between the tip of the spear and the end of the spear a handle, the so-called winding, is arranged on the shaft. This training spear is designed specifically for javelin throwing training serve young people. Its individual components are made of a plastic material.

Nachteilig bei dem bekannten Speer ist, dass er leichter und kleiner als die üblichen Wettkampfspeere ist. In einer Ausführungsform besitzt der bekannte Speer weniger als die halbe Länge eines Wettkampfspeeres. Auch weisen die Wettkampfspeere keine Stabilisierungsflossen auf.A disadvantage of the known spear is that it is lighter and is smaller than the usual competition spears. In one embodiment the well-known spear has less than half Length of a competition spear. Also show the competition spears no stabilizing fins on.

Das Training mit diesem Speer ist zwar auch in einer Halle möglich, entspricht jedoch nicht den Gegebenheiten beim Training mit einem Wettkampfspeer. So wird dieser Speer mit einem deutlich steileren Winkel als ein Wettkampfspeer geworfen.The training with this spear is also in a hall possible, but does not correspond to the conditions during training with a competition javelin. So this spear with one thrown significantly steeper than a competition javelin.

Aus dem Artikel "Starten Sie die Wurfrakete!" der Zeitschrift Leichtathletiktraining, Philippka-Verlag Münster, November 1997, ist eine Bauanleitung für eine Wurfrakete bekannt. Diese Wurfrakete, die eine Bereicherung der "Spielleichtathletik" darstellen soll, weist eine Länge zwischen von 50 und 100 cm auf. Sie besteht aus einem Raketenrumpf, der aus einer Schalenheizungsisolierung für 18 mm Rohre ausgebildet ist. Die Raketenspitze wird dabei ebenso wie das Ende von einem eingeklebten Flaschenkorken gebildet. Zur Herstellung von geeigneten Flugeigenschaften benötigt diese Wurfrakete ein Leitwerk, das aus vier radial angeordneten Stabilisierungsflossen besteht. Der Rumpf, der aus einem hohlen Kunststoffmantel besteht, kann zur besseren Stabilität und Flugeigenschaft mit einem Holzstab versehen werden. From the article "Start the launcher!" the magazine Athletics training, Philippka-Verlag Münster, November In 1997, building instructions for a rocket are known. This Throwing rocket, which enriches the "game athletics" should be between 50 and 100 cm. It consists of a rocket hull, which consists of a Shell heating insulation is designed for 18 mm pipes. The missile tip becomes just like the end of one glued in bottle corks. For the production of suitable This launch rocket requires flight characteristics Tail unit consisting of four radially arranged stabilizing fins consists. The hull, which is made of a hollow plastic jacket exists for better stability and flight characteristics be provided with a wooden stick.

Nachteilig bei diesem Trainingsgerät ist ebenfalls, dass es leichter und kleiner als die üblichen Wettkampfspeere ist. Die max. Länge von 100 cm ist dabei kleiner als die halbe Länge eines Wettkampfspeeres. Auch weisen Wettkampfspeere keine Stabilisierungsflossen auf. Das Training mit diesem Wurfgerät ist zwar auch in einer Halle möglich, entspricht jedoch keinesfalls den Gegebenheiten beim Training mit einem Wettkampfspeer. Die Flugeigenschaften sind relativ gering, da das Volumen und die Oberfläche im Verhältnis zur Masse viel zu groß sind. Für Speerwurfübungen in Schule und Verein ist das Gerät unbrauchbar, denn ein "echter Speer" bzw. "Wettkampfspeer" ist entsprechend Regel 193 der internationalen Wettkampfbedingungen in einer ganz bestimmten Technik zu werfen; man kann ihn aufgrund seiner Maße nicht "irgendwo" greifen und "irgendwie" abwerfen, was mit der "Wurfrakete" möglich ist, so dass sich die erlernte Technik des Speerwurfes eher verschlechtern als verbessern würde. Die Technik des Speerwurfes ist mit solch einem Spielgerät weder vorgesehen noch zu erlernen.Another disadvantage of this training device is that it lighter and smaller than the usual competition spears. The max. The length of 100 cm is less than half Length of a competition spear. Also show competition spears no stabilizing fins on. Training with this Throwing device is also possible in a hall but not the circumstances when training with one Competition javelin. The flight characteristics are relatively low because the volume and the surface in relation to the mass a lot are too big. For spear throwing exercises in schools and clubs the device unusable, because a "real spear" or "competition spear" is international in accordance with Rule 193 Throwing competition conditions in a very specific technique; because of its size, you cannot grab it "anywhere" and "somehow" drop what is possible with the "missile" is so that the learned technique of javelin throw would rather worsen than improve. The technology of Javelin throw is not provided with such a game device still to learn.

Aufgabe der vorliegenden Erfindung ist es daher, einen Speer zu entwickeln, der einerseits für eine Verwendung in einer Halle und andererseits zum Erlernen des Speerwerfens und zu einem wettkampfmäßigen Trainieren geeignet ist.The object of the present invention is therefore a spear to develop one hand for use in a Halle and on the other hand to learn javelin throwing and to is suitable for competitive training.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Speer weitgehend einem Wettkampfspeer angeglichen ist, und dass der Schaft als Kern ausgebildet ist, der von einem Mantel aus einem elastischen Material ummantelt ist.This object is achieved in that the Spear is largely aligned with a competition spear, and that the shaft is formed as a core by a jacket is encased in an elastic material.

Dadurch, dass der Schaft aus einem elastischen Material ummantelt ist, kann der Speer in einer Halle benutzt werden, ohne dass er beim Auftreffen auf dem Hallenboden diesen beschädigt. Because the shaft is encased in an elastic material the spear can be used in a hall, without damaging it when it hits the hall floor.

Dadurch, dass der erfindungsgemäße Speer ist in seinen technischen Merkmalen weitgehend einem Wettkampfspeer angeglichen ist, kann er auch das Mindestgewicht für einen Speer, das je nach Kategorie bzw. Speerwerfer zwischen 400 g und 800 g beträgt, aufweisen. Entsprechend kann die Gesamtlänge eines solchen Speeres je nach Speerwerfer bei mindestens 1.850 mm bis 2.600 mm liegen. Die Mindestentfernung zwischen der Speerspitze und dem Schwerpunkt liegt dann nach den Wettkampfrichtlinien je nach Speerwerfer bei mindestens 750 mm bis 900 mm.The fact that the spear according to the invention is in its technical Characteristics largely adjusted to a competition spear is, it can also be the minimum weight for a spear that ever by category or javelin thrower is between 400 g and 800 g, exhibit. Accordingly, the total length of one such spears depending on the javelin thrower at least 1,850 mm up to 2,600 mm. The minimum distance between the Spearhead and the focus is then according to the competition guidelines depending on the javelin thrower at least 750 mm up to 900 mm.

Mit dem Anmeldungsgegenstand steht damit erstmalig ein "Wettkampfspeer" bzw. ein Speer zur Verfügung, der weitgehend einem Wettkampfspeer angeglichen ist und den wesentlichen Vorteil aufweist, dass er in Hallen oder auch auf Hartplätzen geworfen werden kann, ohne den Hallenboden oder den Hartplatz zu beschädigen. Damit ist es endlich möglich, das Speerwerfen auch dann zu betreiben bzw. zu trainieren, wenn die Wetteroder Rasenverhältnisse das Werfen auf der Wiese nicht erlauben. Für die Arbeit in Schulen und Vereinen ist dies insbesondere im Winter eine große Hilfe. In Schulen wird das Speerwerfen bisher fast gänzlich ausgeklammert, da das Kosten-Nutzen-Verhältnis der bekannten Speere sehr ungünstig ist, so dass sie nicht angeschafft werden. Auch ist das Werfen spitzer Metallspeere in großen Gruppen nicht ungefährlich.For the first time there is a "competition spear" with the subject of registration or a spear available that largely one Competition spear is aligned and the main advantage shows that he is in halls or on hard courts can be thrown without the hall floor or hard court to damage. It is finally possible to throw the javelin to operate or train even when the weather or Lawn conditions do not allow throwing in the meadow. This is particularly true for work in schools and clubs a great help in winter. In schools it will Spear throwing has been almost completely excluded since the cost-benefit ratio of the known spears very unfavorable is so that they cannot be purchased. Throwing is too sharp metal spears in large groups are not harmless.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist der Schaft in einem die Speerspitze umfassenden vorderen Bereich mit einem vorderen Mantel ummantelt. In einem ein der Speerspitze abgewandtes Speerende umfassenden hinteren Bereich ist der Speer mit einem hinteren Mantel ummantelt. According to a preferred embodiment of the invention, the Stem in a front area surrounding the tip of the spear covered with a front coat. In one of the spearheads opposite spear end is comprehensive rear area the spear encased in a rear cloak.

Dadurch, dass der Mantel zweiteilig, das heißt aus einem vorderen Mantel und einem hinteren Mantel ausgebildet ist, ist es möglich, einen herkömmlichen Handgriff zu verwenden. Außerdem ist es leichter, den Mantel am Schaft bzw. am Kern des Schaftes anzubringen.The fact that the coat in two parts, that is, from a front Coat and a rear coat is formed it is possible to use a conventional handle. Moreover it’s easier to attach the jacket to the shaft or core of the To attach the shaft.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist der Mantel, bzw. der vordere Mantel und der hintere Mantel, aus einem Schaumstoff ausgebildet.According to a further preferred embodiment of the invention is the coat, or the front coat and the rear coat, formed from a foam.

Durch die Verwendung eines Schaumstoffes lässt sich ein besonders weicher Mantel erzielen, der beim Aufprall den Hallenboden schont. By using a foam, a special achieve a soft coat that hits the hall floor on impact spares.

Nach einer anderen bevorzugten Ausführungsform der Erfindung ist der Mantel aus einem geschäumten Gummi ausgebildet. Die elastischen Eigenschaften von geschäumten Gummi sind ebenfalls geeignet, den Hallenboden beim Aufprall des Speeres nicht zu verletzen.According to another preferred embodiment of the invention the jacket is made of a foamed rubber. The elastic properties of foamed rubber are also suitable for the hall floor when the spear hits not to hurt.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist der Kern als Holzkern ausgebildet.According to a further preferred embodiment of the invention the core is designed as a wooden core.

Durch die Verwendung eines Holzkernes ist es möglich, dem Speer weitgehend das Gewicht und die Ausmaße eines üblichen Wettkampfspeeres zu geben.By using a wooden core, it is possible to Spear largely the weight and size of a usual To give competition spears.

Es ist aber auch möglich, den Kern als Kunststoffkern bzw. aus einem glasfaserverstärkten Kunststoffkern auszubilden.But it is also possible to use the core as a plastic core or from a glass fiber reinforced plastic core.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist die Speerspitze lösbar mit dem Schaft verbunden. An ihrem dem Schaft abgewandten freien Ende ist die Speerspitze aus einem elastischen Material ausgebildet.According to a further preferred embodiment of the invention the spear tip is detachably connected to the shaft. On hers the free end facing away from the shaft is the tip of the spear formed of an elastic material.

Durch die lösbare Verbindung der Speerspitze ist es beispielsweise möglich, den vorderen Mantel rohrförmig auszubilden und über den Kern zu schieben. Anschließend kann der vordere Mantel durch Verbinden der Speerspitze mit dem Kern an den Schaft bzw. dem Kern in seiner Position fixiert werden. Bei einer Benutzung des Speeres im Freien ist es zudem möglich, die elastische, stumpfe Speerspitze gegen eine spitze Speerspitze auszutauschen.Because of the detachable connection of the spearhead, for example possible to form the front jacket tubular and push it over the core. Then the front one Coat by spearhead connecting to the core the shaft or the core are fixed in their position. When using the spear outdoors, it is also possible to the elastic, blunt spear tip against a point Exchange spearhead.

Gemäß einer weiteren bevorzugten Ausführungsform der Erfindung ist auch das Speerende lösbar mit dem Schaft verbunden und an seinem dem Schaft abgewandten freien Ende aus einem elastischen Material ausgebildet. According to a further preferred embodiment of the invention the spear end is also detachably connected to the shaft and at its free end facing away from the shaft from a elastic material.

So kann beispielsweise der hintere Mantel zwischen Handgriff und Speerende durch Befestigen des Speerendes an dem Schaft fixiert werden.For example, the rear jacket between the handle and spear end by attaching the spear end to the shaft be fixed.

Nach einer weiteren bevorzugten Ausführungsform der Erfindung weist die Speerspitze einen Hohlraum auf, der mit an der Oberfläche der Speerspitze angeordneten Öffnungen verbunden ist. Der Hohlraum ist mit einem Farbstoff befüllbar, der beim Aufschlag des Speeres am Boden aus den Öffnungen austritt.According to a further preferred embodiment of the invention the spearhead has a cavity on the surface the spearhead arranged openings connected is. The cavity can be filled with a dye that the Impact of the spear emerges from the openings on the ground.

Durch den aus der Speerspitze austretenden Farbstoff ist es relativ einfach, den Aufschlagsort des Speeres zu bestimmen.It is due to the dye emerging from the tip of the spear relatively easy to determine the location of the spear.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden ausführlichen Beschreibung und den beigefügten Zeichnungen, in denen bevorzugte Ausführungsformen der Erfindung beispielsweise veranschaulicht sind.Further details of the invention emerge from the following detailed description and the attached Drawings in which preferred embodiments of the invention for example are illustrated.
