The advantage of said wooden surfaces is that they offer a lower risk of injury and exert less stress on the floor of the sports venue or on the training equipment that comes into contact with the dumbbells.

Description

HOLZHANTEL WOOD WEIGHT
Die Erfindung betrifft eine Hantel gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a dumbbell according to the preamble of claim 1.
Aus der Praxis sind derartige Hanteln als Sportgeräte zur Körperertüchtigung bzw. zum Muskelaufbau bekannt. Üblicherweise wird zwischen Kurz- und Langhanteln unterschieden. Hanteln bestehen im allgemeinen aus Metall, welches in manchen Fällen mit Kunststoff ummantelt ist. Kurzhanteln nach dem Stand der Technik bestehen üblicherweise aus einem Handgriff und Metallgewichten, die entweder fest mit dem Handgriff verbunden sind oder austauschbar und lösbar am Handgriff befestigt sind. Lösbare Gewichte bestehen in der Regel aus Metallscheiben mit einer zentralen Bohrung zum H durchführen der Enden des Handgriffs. Langhanteln weisen einen ähnlichen Aufbau auf, nur ist die Hantelstange wesentlich länger als der Handgriff einer Kurzhantel und wird mit beiden Händen gefasst. Handelt es sich um lösbare und austauschbare Gewichte, müssen diese am Handgriff bzw. der Hantelstange fixiert werden, um ein Abgleiten der Gewichte und dadurch mögliche Verletzungen zu verhindern. Die Gewichtssicherung besteht in der Praxis häufig aus einem Metallring, in dessen radialem Umfang eine Schraubbohrung mit Schraube angebracht ist. Der Metallring wird über das Ende der Hantelstange bzw. des Griffs geschoben und hält die Gewichtsscheibe gegen einen Anschlag. Durch Eindrehen der Schraube wird der Schraubenfuß gegen die Oberfläche des Griffs gepresst und fixiert den Metallring und damit die Gewichte gegen Verrutschen. Nachteilig hieran ist, dass keine sichtbare Kontrolle besteht, ob der Metallring fest genug auf der Hantelstange sitzt um insbesondere bei hohen Gewichten die Gewichtsscheiben vom Abrutschen von der Hantelstange zu bewahren. Die bekannten Hantelmaterialien weisen weitere Nachteile auf. Die Verwendung von Metall oder Kunststof- fumhüllungen kann bei Allergikern zu Problemen führen. Beim Einsatz von Metall ohne Kunststofrumhüllung besteht zudem eine erhöhte Verletzungsgefahr für den Sportler und eine erhöhte Beanspruchung des Bodens der Sportstätte bzw. der Trainingsgeräte, welche mit den Hanteln in Berührung kommen.In practice, dumbbells of this type are known as sports equipment for exercising or building muscle. A distinction is usually made between dumbbells and barbells. Dumbbells generally consist of metal, which in some cases is covered with plastic. Dumbbells according to the prior art usually consist of a handle and metal weights, which are either firmly connected to the handle or are attached to the handle in an exchangeable and detachable manner. Detachable weights usually consist of metal disks with a central hole for carrying out the ends of the handle. Barbells have a similar structure, only the barbell is much longer than the handle of a dumbbell and is gripped with both hands. If the weights are detachable and replaceable, they must be fixed to the handle or the barbell to prevent the weights from sliding off and possible injuries. In practice, the weight lock often consists of a metal ring, in the radial circumference of which a screw hole with a screw is made. The metal ring is pushed over the end of the barbell or handle and holds the weight plate against a stop. By screwing in the screw, the screw base is pressed against the surface of the handle and fixes the metal ring and thus the weights against slipping. The disadvantage of this is that there is no visible control as to whether the metal ring is seated firmly enough on the barbell bar in order to prevent the weight plates from slipping off the barbell bar, particularly in the case of heavy weights. The known dumbbell materials have further disadvantages. The use of metal or plastic coatings can cause problems for allergy sufferers. When using metal without a plastic coating, there is also an increased risk of injury for the athlete and an increased strain on the floor of the sports facility or the training equipment that comes into contact with the dumbbells.
Der Erfindung liegt die Aufgabe zugrunde, eine Hantel zu schaffen, die sicher zu handhaben ist und die Nachteile des Standes der Technik weitgehend ausräumt. Diese Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind Gegenstand der Unteransprüche. Erfindungsgemäß besteht die Hantel aus einer Hantelstange und an deren Enden befestigten Metallgewichten, wobei die Oberflächen von Stange und / oder Gewichten aus Holz oder aus einem Holzverbundmaterial, wie z.B. MDF bestehen. Mit MDF wird ein Holzwerkstoff bezeichnet, bei dem Holzfasern mit Leim vermischt und gepresst werden, wodurch eine hohe Formstabilität des Werkstoffes erreicht wird. Im folgenden wird auf den Zusatz, dass als Material auch MDF in Frage kommt verzichtet. Wenn von Holz die Rede ist, soll gleichzeitig immer auch die gleichwertige Alternative des Holzwerkstoffes MDF gemeint sein. Die Gewichte sind vorzugsweise lösbar und austauschbar an der Hantelstange befestigt, es ist jedoch auch durchaus möglich, diese fest mit der Hantelstange zu verbinden, ohne dass dies der prinzipiellen Idee der Erfindung zuwiderläuft. Die Hantelstange kann als Kurz- oder Langhantelstange ausgebildet sein und ist vorzugsweise eine Vollholzstange aus Massivholz, MDF oder einem vergleichbaren Holzverbundmaterial. Erfindungsgemäß verfügen die Gewichte über einen Kern aus Metall, vorzugsweise Eisen. Dieser Kern wird von einer Holz- Ummantelung vorzugsweise komplett umschlossen. In einer bevorzugten Ausführungsform besteht die Ummantelung aus zwei Holzscheiben, welche eine Vertiefung oder Ausformung auf einer Seite aufweisen, um den Kern aus Metall aufzunehmen. Die Scheiben funktionieren dabei wie Schalen und die Vertiefungen oder Ausformungen sollten so tief sein, dass der Metallkern vollständig von den beiden Scheiben oder Schalen umschlossen werden kann. Die Scheiben und der Metallkern sind mit ausreichend großen Bohrungen zur Aufnahme der Enden der Hantelstange versehen. Der umlaufende Rand, an dem sich die beiden Scheiben oder Schalen berühren, ist vorzugsweise verleimt oder versiegelt.The invention has for its object to provide a dumbbell that is safe to use and largely eliminates the disadvantages of the prior art. This object is achieved with the characterizing features of claim 1. Advantageous further developments are the subject of the dependent claims. According to the invention, the dumbbell consists of a dumbbell bar and metal weights attached to the ends thereof, the surfaces of the bar and / or weights consisting of wood or a wood composite material such as MDF. MDF is a wood-based material in which wood fibers are mixed with glue and pressed, which ensures that the material is dimensionally stable. In the following, the addition that MDF is also suitable as a material is dispensed with. When talking about wood, the equivalent alternative of wood-based material MDF should always be meant. The weights are preferably detachably and interchangeably attached to the barbell, but it is also entirely possible to firmly connect them to the barbell without this contradicting the basic idea of the invention. The barbell bar can be designed as a short or barbell bar and is preferably a solid wood bar made of solid wood, MDF or a comparable wood composite material. According to the invention, the weights have a core made of metal, preferably iron. This core is preferably completely enclosed by a wooden casing. In a preferred embodiment, the casing consists of two wooden disks, which have a recess or shape on one side to accommodate the metal core. The disks function like shells and the depressions or recesses should be so deep that the metal core can be completely enclosed by the two disks or shells. The discs and the metal core are provided with sufficiently large holes to accommodate the ends of the barbell. The peripheral edge at which the two panes or shells touch is preferably glued or sealed.
In einer besonders bevorzugten Ausfuhrungsform weisen die beiden Holzscheiben auf der Seite der Vertiefung kreisrunde Vorsprünge um ihre zentrale Bohrung auf, die in die Bohrung des Metallkerns eingreifen. Auf diese Weise wird der Metallkern innerhalb der durch die beiden Scheiben gebildeten Umhüllung fixiert, und das Einführen der Hantelstange in die Bohrungen vereinfacht. Außerdem wird somit verhindert, dass der Metallkern die Oberfläche der Hantelstange beschädigt.In a particularly preferred embodiment, the two wooden disks on the side of the depression have circular projections around their central bore, which engage in the bore of the metal core. In this way, the metal core is fixed within the envelope formed by the two disks, and the insertion of the barbell into the bores is simplified. It also prevents the metal core from damaging the surface of the barbell.
In einer vorteilhaften Weiterbildung verfugt die Hantelstange an ihren Enden über Außengewinde zur Fixierung der aufgelegten Gewichte. Eine Fixierung kann dabei über eine Holz- mutter erfolgen, welche nach Auflegen der Gewichte auf das Gewinde geschraubt wird und die Gewichte gegen einen an der Hantelstange vorgesehen Anschlag hält. Die Mutter hat vorzugsweise die Form einer Ellipse, um das Aufschrauben von Hand zu erleichtern, es sind jedoch auch andere Formen denkbbar, welche dem Nutzer einen vorteilhaften Hebel zum Auf- und Abschrauben der Mutter bieten.In an advantageous development, the barbell bar has external threads at its ends for fixing the weights placed on it. Fixation can be done using a wooden nut, which is screwed onto the thread after placing the weights and holds the weights against a stop provided on the barbell. The nut preferably has the shape of an ellipse in order to facilitate screwing on by hand, but other shapes are also conceivable which offer the user an advantageous lever for screwing the nut on and off.
In einer alternativen Ausfuhrungsform verfugt nur eine der beiden Holzscheiben über eine Vertiefung zur Aufnahme des Metallkerns, und die andere Scheibe ist im wesentlichen flach und liegt so auf der ersten Holzscheibe auf, dass die Vertiefung abgedeckt wird. Die Ränder der Holzscheiben können mit korrespondierenden Absätzen versehen sein, um das zentrieren der beiden Holzscheiben zu vereinfachen.In an alternative embodiment, only one of the two wooden disks has a depression for receiving the metal core, and the other disk is essentially flat and lies on the first wooden disk so that the depression is covered. The edges of the wooden disks can be provided with corresponding shoulders in order to simplify the centering of the two wooden disks.
Im folgenden wird die Erfindung anhand der beigefügten Zeichnungen näher erläutert, wobeiIn the following the invention is explained in more detail with reference to the accompanying drawings, wherein
Figur 1 drei Ausfuhrungsformen von Hantelstangen zeigt,FIG. 1 shows three embodiments of barbell bars,
Figur 2 eine schematische Darstellung der Zusammenfügung von Hantelstange undFigure 2 is a schematic representation of the assembly of barbell and
Gewicht ist, undWeight is, and
Figur 3 den Aufbau eines Gewichts in schematischer Darstellung zeigt.Figure 3 shows the structure of a weight in a schematic representation.
In Figur 1 sind zwei Kurzhantelstangen 10, 12 und eine Langhantelstange 14 aus Holz abgebildet. Die Hantelstangen verfügen an ihren Enden über Außengewinde 16. Am Übergang von Außengewinde zur Griffstange befinden sich Absätze 18, die als Anschläge für die Gewichte dienen. Die Griffoberflächen an den Hantelstangen 12 und 14 sind glatt und an der Hantelstange 10 geschwungen, um einen besseren Griff zu ermöglichen. Alternativ sind auch bei der Langhantelstange 14 geschwungene Griff-Flächen denkbar, oder aber andere Muster oder Formen, welche die Griffigkeit der Hantelstangen erhöhen.In Figure 1, two dumbbell bars 10, 12 and a barbell bar 14 made of wood are shown. The barbell bars have external threads 16 at their ends. At the transition from the external thread to the handle bar there are shoulders 18 which serve as stops for the weights. The handle surfaces on the barbell bars 12 and 14 are smooth and curved on the barbell bar 10 to provide a better grip. Alternatively, curved handle surfaces are also conceivable for the barbell bar 14, or other patterns or shapes which increase the grip of the barbell bars.
Wie in Figur 2 illustriert, werden die Gewichte auf die Bereiche der Hantelstange mit Außengewinde geschoben. Anschließend werden die Gewichte mit Schraubmuttern (nicht ab- gebildet) aus Holz fixiert. Die Schraubmuttern sind besonders vorteilhaft ellipsenförmig ausgebildet und lassen sich somit einfacher von Hand an- und abschrauben.As illustrated in Figure 2, the weights are pushed onto the areas of the barbell with an external thread. Then the weights are tightened with screw nuts (not formed) made of wood. The screw nuts are particularly advantageously elliptical and can therefore be screwed on and off more easily by hand.
Die in den Figuren 2 und 3 dargestellten Gewichtsscheiben bzw. deren Bestandteile sind im Wesentlichen rund. Die radialen, von den Zentren ausgehenden Linien dienen in den Zeichnungen nur der besseren räumlichen Darstellbarkeit und sollen insbesondere nicht andeuten, dass die einzelnen Bestandteile der Gewichte aus segmentförmigen Elementen zusammengesetzt sind, obwohl dies im Rahmen der Erfindung natürlich eine mögliche Ausführungsform sein kann.The weight disks or their components shown in FIGS. 2 and 3 are essentially round. The radial lines emanating from the centers only serve for better spatial representation in the drawings and in particular should not imply that the individual components of the weights are composed of segment-shaped elements, although this can of course be a possible embodiment within the scope of the invention.
Die Gewichtsscheiben sind rund und dreiteilig aufgebaut. Sie bestehen im Wesentlichen aus zwei runden Holzscheiben 20, 22 und einer runden Metallscheibe 24, welche im zusammengebauten Zustand von den beiden Holzscheiben 20, 22 umschlossen ist. Die Holzscheiben weisen auf je einer Seite eine runde Vertiefung 26 zur Aufnahme der Metallscheibe 24 auf. Die Tiefe dieser Vertiefung beträgt in etwa die Hälfte der Dicke der Metallscheibe 24, so dass die Metallscheibe im zusammengebauten Zustand von den beiden Vertiefungen in den Holzscheiben vollständig aufgenommen ist und die äußeren Ränder der Holzscheiben aneinander anliegen. Die runden Holzscheiben 20, 22 und die Metallscheibe 24 weisen in ihrem Zentrum eine Bohrung 28, 32 zur Durchführung eines Hantelendes auf. Auf der Seite der Vertiefung 26 weisen die Bohrungen 28 der Holzscheiben 20, 22 einen ringförmigen Vorsprung 30 auf, der um den Bohrlochrand verläuft. Vorzugsweise sind die beiden Scheiben 20, 22 identisch, alternativ kann jedoch bei einer der beiden Scheiben auf den ringförmigen Vorsprung 30 verzichtet werden. Die Metallscheibe 24 weist in ihrem Zentrum eine Bohrung 32 auf, deren Umfang in etwa dem äußeren Umfang des ringförmigen Vorsprungs 30 entspricht, so dass dieser Vorsprung 30 im zusammengebauten Zustand in die Bohrung 32 der Metallscheibe eingreift und diese innerhalb der Vertiefungen 26 zentriert.The weight plates are round and three-part. They essentially consist of two round wooden disks 20, 22 and a round metal disk 24 which, when assembled, is enclosed by the two wooden disks 20, 22. The wooden disks have a round recess 26 on each side for receiving the metal disk 24. The depth of this depression is approximately half the thickness of the metal disk 24, so that the metal disk is completely absorbed by the two depressions in the wooden disks in the assembled state and the outer edges of the wooden disks abut one another. The round wooden disks 20, 22 and the metal disk 24 have a bore 28, 32 in their center for the passage of a dumbbell end. On the side of the recess 26, the bores 28 of the wooden disks 20, 22 have an annular projection 30 which extends around the edge of the borehole. The two disks 20, 22 are preferably identical, but alternatively the annular projection 30 can be dispensed with in one of the two disks. The metal disc 24 has a bore 32 in its center, the circumference of which corresponds approximately to the outer circumference of the annular projection 30, so that this projection 30 engages in the assembled state in the bore 32 of the metal disc and centers it within the recesses 26.
Die Erfindung ist nicht auf das obige Ausführungsbeispiel beschränkt, insbesondere kann die Holzumrnantelung der Metallscheibe auch auf andere Art und Weise erfolgen, indem z.B. nur eine der Holzscheiben eine Vertiefung zur Aufnahme der Metallscheibe aufweist, und sozusagen als Schale dient und die andere Holzscheibe flach ist und wie ein Deckel auf der durch die Vertiefung gebildeten Schale aufliegt. The invention is not limited to the above exemplary embodiment, in particular the wood sheathing of the metal disk can also be done in another way, e.g. only one of the wooden disks has a recess for receiving the metal disc, and serves as a shell, so to speak, and the other wooden disc is flat and rests on the shell formed by the recess like a lid.
