Description

Speerspear
Beschreibungdescription
Die Erfindung betrifft einen Speer, insbesondere 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, in particular for use in a hall, consisting essentially of a shaft, the spear tip is blunt and which has a handle near its center of gravity.
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 have a pointed spear tip with which they penetrate into the ground and get stuck. These spears are therefore not suitable for use in a hall.
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 hinte- ren 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 Komponen- ten sind aus einem Kunststoffmaterial gefertigt.Furthermore, from WO 98/18400 a spear for training purposes is known which has a blunt spear tip which is arranged at the front end of a shaft. At its rear spear end, the shaft has three radially arranged stabilizing fins. A handle, the so-called winding, is arranged on the shaft between the tip of the spear and the end of the spear. This training spear is intended specifically for the javelin training of young exercisers. 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.The disadvantage of the known spear is that it is lighter and smaller than the usual competition spears. In one embodiment, the known spear is less than half the length of a competition spear. The competition spears also have no stabilizing fins.
Das Training mit diesem Speer ist zwar auch in einer Halle möglich, entspricht jedoch nicht den Gegebenheiten beim Trai- ning mit einem Wettkampfspeer. So wird dieser Speer mit einem deutlich steileren Winkel als ein Wettkampfspeer geworfen.Training with this spear is also possible in a hall, but does not correspond to the conditions when training with a competition spear. This spear is thrown at a much steeper angle than a competition spear.
Aufgabe der vorliegenden Erfindung ist es daher, einen Speer zu entwickeln, der einerseits für eine Verwendung in einer Halle geeignet ist und andererseits weitgehend einem Wettkampfspeer angeglichen ist.It is therefore an object of the present invention to develop a spear that is suitable for use in a hall on the one hand and is largely adapted to a competition spear on the other hand.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Schaft als Kern ausgebildet ist, der von einem Mantel aus einem elastischen Material ummantelt ist.This object is achieved according to the invention in that the shaft is designed as a core, which is encased by a jacket made of 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 covered with an elastic material, the spear can be used in a hall without being damaged when it hits the hall floor.
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 shaft is encased in a front area surrounding the spear tip with a front jacket. The spear is encased in a rear cladding in a rear region that surrounds a spear end facing away from the tip of the spear.
Dadurch, dass der Mantel zweiteilig, dass 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.Because the jacket is formed in two parts, that is to say from a front jacket and a rear jacket, it is possible to use a conventional handle. It is also easier to attach the sheath to the shaft or core of 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, the jacket, or the front jacket and the rear jacket, is formed from a foam.
Durch die Verwendung eines Schaumstoffes lässt sich ein be- sonders weicher Mantel erzielen, der beim Aufprall den Hallenboden schont. 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.The use of a foam makes it possible to achieve a particularly soft jacket that protects the hall floor in the event of an impact. 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 not to damage the hall floor when the spear strikes.
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 give the spear largely the weight and dimensions of a normal competition spear.
Es ist aber auch möglich, den Kern als Kunststoffkern bzw. aus einem glasfaserverstärkten Kunststoffkern auszubilden.However, it is also possible to design 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. At its free end facing away from the shaft, the spear tip is formed from 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 vor- dere 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.The detachable connection of the spear tip makes it possible, for example, to design the front jacket in a tubular shape and to push it over the core. The front sheath can then be fixed in position by connecting the spear tip to the core on the shaft or core. When using the spear outdoors, it is also possible to replace the elastic, blunt spear tip with a pointed spear tip.
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. So kann beispielsweise der hintere Mantel zwischen Handgriff und Speerende durch Befestigen des Speerendes an dem Schaft fixiert werden.According to a further preferred embodiment of the invention, the spear end is also detachably connected to the shaft and is formed from an elastic material at its free end remote from the shaft. For example, the rear sheath can be fixed between the handle and the spear end by attaching the spear end to the shaft.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung weist die Speerspitze einen Hohlraum auf, der mit an der 0- berfläche 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 which is connected to openings arranged on the surface of the spearhead. The cavity can be filled with a dye that emerges from the openings when the spear hits the ground.
Durch den aus der Speerspitze austretenden Farbstoff ist es relativ einfach, den Aufschlagsort des Speeres zu bestimmen.The dye emerging from the tip of the spear makes it relatively easy to determine the point of impact of the spear.
Weitere Einzelheiten der Erfindung ergeben sich aus der nach- folgenden ausführlichen Beschreibung und den beigefügten Zeichnungen, in denen bevorzugte Ausführungsformen der Erfindung beispielsweise veranschaulicht sind.Further details of the invention will become apparent from the following detailed description and the accompanying drawings, in which preferred embodiments of the invention are illustrated, for example.

Ein Speer 1 besteht im wesentlichen aus einem Schaft 2, einer Speerspitze 3, einem Handgriff 4 und einem Speerende 5.A spear 1 essentially consists of a shaft 2, a spear tip 3, a handle 4 and a spear end 5.
Der Schaft 2 besteht aus einem Kern 6, der von einem Mantel 7 aus einem elastischen Material ummantelt ist. Der Mantel 7 ist aus einem Schaumstoff ausgebildet. Es kann aber auch ein Natur- oder Kunst autschukmaterial verwendet werden. Beispielsweise ist auch geschäumter Gummi geeignet.The shaft 2 consists of a core 6, which is covered by a jacket 7 made of an elastic material. The jacket 7 is formed from a foam. However, a natural or synthetic rubber material can also be used. For example, foamed rubber is also suitable.
Der Mantel 7 besteht in einem der Speerspitze 3 zugewandten vorderen Bereich 8 aus einem vorderen Mantel 9 und in einem dem Speerende 5 zugewandten hinteren Bereich 10 aus einem hinteren Mantel 11.The jacket 7 consists of a front jacket 8 in a front area 8 facing the spear tip 3 and a rear jacket 11 in a rear area 10 facing the spear end 5.
Der Kern 6 ist als Holzkern ausgebildet. Es ist aber auch möglich, den Kern als Kunststoffkern auszubilden. Auch kann der Kern aus einem glasfaserverstärkten Kunststoff als Hohlkörper hergestellt werden. Auch ist es grundsätzlich möglich, den Kern aus einem Metall auszubilden.The core 6 is designed as a wooden core. However, it is also possible to design the core as a plastic core. The core can also be produced from a glass fiber reinforced plastic as a hollow body. In principle, it is also possible to form the core from a metal.
Zwischen dem vorderen Bereich 8 und dem hinteren Bereich 10 ist etwa im Bereich des Schwerpunktes der Handgriff 4 angeordnet. Der Handgriff ist über eine Griffhülse 12 an dem Kern 6 befestigt. Auf der Griffhülse 12 ist eine Griffschnür 13 angeordnet, die die eigentliche Grifffläche bildet.The handle 4 is arranged between the front area 8 and the rear area 10 approximately in the area of the center of gravity. The handle is attached to the core 6 via a grip sleeve 12. A grip cord 13 is arranged on the grip sleeve 12 and forms the actual grip surface.
Es ist grundsätzlich aber auch möglich, auf die Griffhülse zu verzichten und den Mantel 7 durchgängig über den Schaft auszubilden. Die Griffschn r 13 kann dann direkt auf den Mantel 7 angebracht werden. Die Speerspitze 3 ist, wie auch das Speerende 5, lösbar über ein Gewinde mit dem Schaft 2 verbunden. Die Speerspitze 3 ist an ihrem dem Schaft 2 abgewandten freien Ende 14 aus einem elastischen Material ausgebildet. Das Speerende 5 ist ebenfalls an seinem dem Schaft abgewandten freien Ende 15 aus einem elastischen Material ausgebildet. Der vordere Mantel 9 ist zwischen der Speerspitze 3 und dem Handgriff 4 angeordnet. Der hintere Mantel 11 ist zwischen dem Handgriff und dem Speerende 5 angeordnet.In principle, however, it is also possible to dispense with the grip sleeve and to design the jacket 7 continuously over the shaft. The Griffschn r 13 can then be attached directly to the jacket 7. The spear tip 3, like the spear end 5, is detachably connected to the shaft 2 by means of a thread. The spear tip 3 is formed at its free end 14 facing away from the shaft 2 from an elastic material. The spear end 5 is also formed at its free end 15 facing away from the shaft from an elastic material. The front jacket 9 is arranged between the spear tip 3 and the handle 4. The rear jacket 11 is arranged between the handle and the spear end 5.
Nach einer anderen Ausführungsform ist die Speerspitze 3' fest mit dem Kern 6' verbunden. Die Speerspitze 3' wird ebenfalls von dem Mantel 7' ummantelt.According to another embodiment, the spear tip 3 'is firmly connected to the core 6'. The spearhead 3 'is also covered by the jacket 7'.
Nach einer weiteren Ausführungsform weist die lösbare Speerspitze 3'' einen Hohlraum 16 auf, der mit an der Oberfläche der Speerspitze 3'' angeordneten Öffnungen 17 über Kanäle 18 verbunden ist. An ihrem dem Schaft zugewandten Ende weist die Speerspitze 3'' einen Füllkanal 19 zum Befüllen des Hohlrau- mes 16 auf.According to a further embodiment, the releasable spear tip 3 ″ has a cavity 16 which is connected to openings 17 arranged on the surface of the spear tip 3 ″ via channels 18. At its end facing the shaft, the spear tip 3 ″ has a filling channel 19 for filling the cavity 16.
Zur Montage des Speeres 1 wird der vordere Mantel 9 über den vorderen Bereich 8 des Schaftes 2 bzw. des Kernes 6 geschoben, so dass der vordere Mantel 9 mit seinem der Speerspitze 3 abgewandten Ende gegen den Handgriff 4 anschlägt. Durch Einschrauben der Speerspitze 3 in den Kern 6 wird der vordere Mantel 9 zwischen dem Handgriff bzw. dessen Griffhilfe 12 und der Speerspitze 3 fixiert.To assemble the spear 1, the front casing 9 is pushed over the front region 8 of the shaft 2 or the core 6, so that the front casing 9 strikes against the handle 4 with its end facing away from the spear tip 3. By screwing the spear tip 3 into the core 6, the front casing 9 is fixed between the handle or its grip aid 12 and the spear tip 3.
Der hintere Mantel 11 wird über den hinteren Bereich 10 des Schaftes 2 bzw. des Kernes 6 geschoben, so dass sein dem Speerende abgewandtes Ende gegen den Handgriff 4 anschlägt. Durch Einschrauben des Speerendes 5 in den Kern 6 wird der hintere Mantel 11 auf dem Kern 6 fixiert. The rear sheath 11 is pushed over the rear region 10 of the shaft 2 or the core 6, so that its end facing away from the spear end strikes the handle 4. By screwing the spear end 5 into the core 6, the rear casing 11 is fixed on the core 6.
