Description

Die Erfindung betrifft eine Sporthantel.The invention relates to a sports gown.

Aus der DE 8135835 U1 ist eine Kurzhantel bekannt. Die Kurzhantel besteht aus zwei hohlen Hantelkörpern, die an einem Mittelstück festgeschraubt sind.From the DE 8135835 U1 is known a dumbbell. The dumbbell consists of two hollow dumbbell bodies that are screwed to a center piece.

Aus der DE 76154073 U ist eine Hantel bekannt, die aus einem Kunststoffhohlkörper hergestellt ist, der eine mit einer Gewindeschraube verschließbare Öffnung zum Einführen von Wasser aufweist.From the DE 76154073 U a dumbbell is known which is made from a plastic hollow body which has an opening which can be closed with a threaded screw for introducing water.

Die Hanteln bewirken bei der Betätigung eine Belastung der Handgelenke, die nachteilig ist und auf die Dauer zu Verletzungen durch Überbeanspruchung führen kann.The dumbbells cause stress on the wrists when they are operated, which is disadvantageous and in the long run can lead to injuries due to overuse.

Aus der JP S52 138874 U ist eine Hantel zum Trainieren von Kampfsportarten beschrieben gemäß dem Oberbegriff des Anspruchs 1, die einen Griffabschnitt und einen Gewichtsabschnitt aufweist, die O-förmig miteinander verbunden sind und relativ klein dimensioniert sind. Die Hantel liegt beim Training fest in der Hand des Trainierenden.From the JP S52 138874 U a dumbbell for practicing martial arts is described according to the preamble of claim 1, which has a handle section and a weight section which are connected to one another in an O-shape and are relatively small in size. The dumbbell lies firmly in the hand of the person exercising during training.

In der US 5,761,767 ist ein ergonomisch geformter Griff beschrieben.In the U.S. 5,761,767 describes an ergonomically shaped handle.

In der US 7,824,312 B1 ist ein unter Vorspannung stehender Handgriff offenbart, der das Trainieren der Handmuskulatur ermöglicht.In the US 7,824,312 B1 discloses a pre-tensioned handle that enables the hand muscles to be trained.

In der US 8,684,889 B1 ist ein an eine herkömmliche Hantel montierbarer Griff offenbart, der gelenkig mit der Hantel verbunden ist.In the US 8,684,889 B1 discloses a handle mountable to a conventional dumbbell and hingedly connected to the dumbbell.

In der JP 10033615 ist eine symmetrisch ausgebildete Hantel mit einem Griff offenbart, der fest mit den Fingern einer Hand gegriffen werden kann und während des Trainings fest in der Hand liegt.In the JP 10033615 discloses a symmetrically designed dumbbell with a handle which can be firmly gripped with the fingers of one hand and which lies firmly in the hand during exercise.

In der DE 247381 ist eine Hantel mit einer Hubgewichtsanordnung, deren Schwerpunkt gegenüber der Griffstange versetzt ist, offenbart. Die Anordnung ist in der Konstruktion sehr aufwändig.In the DE 247381 discloses a dumbbell with a lifting weight arrangement whose center of gravity is offset with respect to the handlebar. The arrangement is very complex to construct.

Aus der DE 20 2012 003 777 U1 ist eine Fausthantel bekannt, deren Gewicht mittels der Hand umfasst wird.From the DE 20 2012 003 777 U1 a hand dumbbell is known, the weight of which is grasped by means of the hand.

Aus dem deutschen Geschmacksmuster DE 40 2011 001 849 ist eine asymmetrische Hantel bekannt.From the German design DE 40 2011 001 849 is known as an asymmetrical dumbbell.

Der Nachteil der oben genannten Hantel ist die asymmetrische Gewichtsverteilung entlang der Griffachse.The disadvantage of the above dumbbell is the asymmetrical weight distribution along the handle axis.

Aus der US 2014/0024506 A1 ist eine Sporthantel mit zwei seitlichen Gewichten bekannt, die durch eine Verbindungsstange miteinander verbunden sind, von der ein Griff abgeht. Nachteilig an der Hantel ist die instabile Lage auf dem Handgelenk des Sportlers.From the US 2014/0024506 A1 a sports gown with two side weights is known which are connected to one another by a connecting rod from which a handle extends. The disadvantage of the dumbbell is the unstable position on the athlete's wrist.

Es ist Aufgabe der Erfindung, eine Hantel der eingangs genannten Art zur Verfügung zu stellen, die besonders handgelenkschonende Übungen ermöglicht.It is the object of the invention to provide a dumbbell of the type mentioned at the outset which enables exercises that are particularly gentle on the wrist.

Die Aufgabe wird durch eine eingangs genannte Hantel mit den Merkmalen des Anspruchs 1 erfüllt.The object is achieved by a dumbbell mentioned at the beginning with the features of claim 1.

Die erfindungsgemäße Sporthantel weist einen Griffabschnitt auf, der entlang einer Griffachse verläuft, und eine vom Griffabschnitt senkrecht zur Griffachse beabstandete und parallel zur Griffachse verlaufende Auflagenachse eines Auflagenabschnitts, der mit wenigstens einem Ende mit dem Griffabschnitt relativ unbeweglich verbunden ist. Die Sporthantel weist einen Schwerpunkt auf, der innerhalb des Auflagenabschnitts angeordnet ist, und ein Abstand zwischen der Griffachse und der Auflagenachse beträgt wenigstens 11 cm. Die Sporthantel bildet einen geschlossen ringförmigen oder offen ringförmigen Korpus in ihrer äußeren Form aus. Unter geschlossen ringförmig wird hier sehr allgemein eine geschlossene äußere Form verstanden, die eine Durchgriffsöffnung und den sie umgebenden Korpus aufweist. Sie muss nicht streng kreisförmig ausgebildet sein. Unter offen ringförmig wird die eben beschriebene äußere Form des Korpus verstanden, in deren umlaufendem Ring ein Segment fehlt. Der Korpus ist dann im Wesentlichen U-förmig oder U-förmig mit aufeinanderzuweisenden U-Enden.The sports gown according to the invention has a handle section that runs along a handle axis, and a support axis of a support section, which is relatively immovably connected to the handle section at least one end, at a distance from the handle section perpendicular to the handle axis and parallel to the handle axis. The sports jacket has a center of gravity which is arranged within the support section, and a distance between the grip axis and the support axis is at least 11 cm. The sports jacket forms a closed ring-shaped or open ring-shaped body in its outer shape. Here, closed ring-shaped is understood very generally to mean a closed outer shape which has a passage opening and the body surrounding it. It does not have to be strictly circular. Open ring-shaped is understood to mean the outer shape of the body just described, in the circumferential ring of which a segment is missing. The body is then essentially U-shaped or U-shaped with U ends facing one another.

Durch die erfindungsgemäße Kombination des Abstandes zwischen Auflagenachse und Griffachse sowie der Anordnung des Schwerpunktes innerhalb des Auflagenabschnittes, dort vorzugsweise in Ausdehnung des Auflagenabschnittes in Richtung der Auflagenachse mittig, kann die Hantel vom Sportler an der Griffachse gegriffen werden und mit dem Auflagenabschnitt auf dem handseitigen Ende des Unterarmes abgelegt werden, wobei zur Überwindung der Trägheit der Hantel bei der Durchführung von Sportübungen eine Kraft gegen den Schwerpunkt der Hantel ausgeübt wird, die mit dem Unterarm erzeugt wird und dabei keine Drehmomente im Handgelenk oder im Arm hervorruft. Eine derartige Hantel eignet sich zur Durchführung von besonders schonenden Sportübungen.Due to the inventive combination of the distance between the support axis and the grip axis and the arrangement of the center of gravity within the support section, there preferably in the extension of the support section in the direction of the support axis, the dumbbell can be gripped by the athlete on the grip axis and with the support section on the hand-side end of the Forearm are put down, whereby to overcome the inertia of the dumbbell when performing sports exercises, a force is exerted against the center of gravity of the dumbbell, which is generated with the forearm and thereby does not cause any torque in the wrist or arm. Such a dumbbell is suitable for performing particularly gentle sports exercises.

Unter einer Sporthantel ist hier eine Kurzhantel zu verstehen, die mit einer Hand des Sportlers greifbar ist und auch dazu bestimmt ist. Die Ausdehnung der Hantel entlang der Griffachse beträgt vorzugsweise höchstens 30 cm, vorzugsweise liegt sie zwischen 20 cm und 30 cm.A sports bell is here to be understood as a dumbbell that can be grasped with one hand of the athlete and is also intended to do so. The extension of the dumbbell along the handle axis is preferably at most 30 cm, preferably between 20 cm and 30 cm.

Vorzugsweise liegt der Abstand zwischen Griffachse und Auflagenachse zwischen 11 cm und 13 cm. Der Griffabschnitt ist vorzugsweise über seine gesamte Ausdehnung entlang der Griffachse gleich und im Querschnitt senkrecht zur Griffachse kreisförmig ausgebildet und weist einen Durchmesser von etwa 3 cm auf. Der Auflagenabschnitt ist im Querschnitt senkrecht zur Auflagenachse entlang der Auflagenachse vorzugsweise gleichförmig und kreisförmig ausgebildet mit einem Durchmesser zwischen 4 cm bis 5,5 cm. Der Abstand von den sich gegenüberliegenden Innenwandungen des Griffabschnittes und des Auflagenabschnitts liegt bei etwa 6 cm.The distance between the handle axis and the support axis is preferably between 11 cm and 13 cm. The handle section is preferably the same over its entire extent along the handle axis and is circular in cross section perpendicular to the handle axis and has a diameter of approximately 3 cm. The support section is preferably uniform and circular in cross section perpendicular to the support axis along the support axis with a diameter between 4 cm and 5.5 cm. The distance from the opposing inner walls of the handle section and the support section is about 6 cm.

Der Auflagenabschnitt ist vorzugsweise schwerer als der Griffabschnitt ausgebildet, um die Verlagerung des Schwerpunktes in der beanspruchten Weise zu erzielen.The support section is preferably designed to be heavier than the grip section in order to achieve the shift of the center of gravity in the claimed manner.

Vorzugsweise bildet die Hantel einen geschlossen ringförmigen Korpus in ihrer äußeren Form aus. Dazu weisen günstigerweise der Griffabschnitt entlang der Griffachse sich gegenüberliegend ein erstes und ein zweites Ende und der Auflagenabschnitt entlang der Auflagenachse sich gegenüberliegend ein erstes und zweites Ende auf. Das erste Ende des Griffabschnitts ist mit dem ersten Ende des Auflagenabschnitts und das zweite Ende des Griffabschnitts mit dem zweiten Ende des Auflagenabschnittes über einen ersten bzw. zweiten Verbindungsabschnitt verbunden. Unter einer ringförmigen Außenform wird hier eine geschlossene Außenform verstanden, die in etwa eine ringförmige Gestalt, also eine geschlossene Gestalt aufweist mit einem vorzugsweise einzigen Durchgriffsloch für die Hand des Sportlers.The dumbbell preferably forms a closed, ring-shaped body in its outer shape. For this purpose, the grip section along the grip axis advantageously has a first and a second end opposite one another and the support section along the support axis has a first and second end opposite one another. The first end of the handle section is connected to the first end of the support section and the second end of the handle section is connected to the second end of the support section via a first and second connecting section. A ring-shaped outer shape is understood here to mean a closed outer shape which has an approximately ring-shaped shape, that is to say a closed shape with a preferably single penetration hole for the athlete's hand.

In einer alternativen Ausführungsform bildet die Hantel einen im Wesentlichen U-förmigen oder U-förmigen Korpus aus. Der Griffabschnitt weist entlang der Griffachse sich gegenüberliegend ein erstes und ein zweites Ende auf, und der Auflagenabschnitt weist entlang der Auflagenachse sich gegenüberliegend ein erstes und ein zweites Ende auf. Das erste Ende des Griffabschnitts ist mit dem ersten Ende des Auflagenabschnitts mittels eines ersten Verbindungsabschnitts verbunden, aber das zweite Ende des Griffabschnitts weist keine direkte Verbindung mit dem zweiten Ende des Auflagenabschnitts auf.In an alternative embodiment, the dumbbell forms an essentially U-shaped or U-shaped body. The handle section has a first and a second end opposite one another along the handle axis, and the support section has a first and a second end opposite one another along the support axis. The first end of the handle section is connected to the first end of the support section by means of a first connection section, but the second end of the handle section has no direct connection to the second end of the support section.

Vorzugsweise beträgt ein maximaler Durchmesser des Auflagenabschnitts zwischen 8,5 cm bis 12 cm, und ein minimaler Durchmesser des Griffabschnitts liegt bei 3 cm.Preferably, a maximum diameter of the support section is between 8.5 cm to 12 cm, and a minimum diameter of the handle section is 3 cm.

In einer anderen Ausführungsform der erfindungsgemäßen Sporthantel ist der maximale Durchmesser des Auflagenabschnitts höchstens dreimal so hoch wie ein minimaler Durchmesser des Griffabschnitts.In another embodiment of the sports jacket according to the invention, the maximum diameter of the support section is at most three times as high as a minimum diameter of the handle section.

Beide Ausführungsformen ermöglichen es, die Hantel zum einen mit einer Hand angenehm zu fassen und dennoch durch den größeren Auflagenabschnitt eine Gewichtsverteilung in Richtung des Unterarmes des Sportlers vorzunehmen.Both embodiments make it possible, on the one hand, to grasp the dumbbell comfortably with one hand and nevertheless to distribute the weight in the direction of the athlete's forearm due to the larger support section.

In einer besonders bevorzugten Ausführungsform der erfindungsgemäßen Sporthantel ist an ersten und zweiten Enden des Griffabschnittes jeweils ein Ende eines Bandes vorgesehen. Bei dem Band kann es sich um ein elastisches und günstigerweise auch um ein längenverstellbares Band handeln.In a particularly preferred embodiment of the sports jacket according to the invention, one end of a strap is provided at each of the first and second ends of the handle section. The band can be an elastic band, and advantageously also a length-adjustable band.

Vorzugsweise ist die gesamte Sporthantel in ihrer Außenform vollflächig von einem Kunststoffüberzug überzogen. Die Sporthantel kann als ein einzelnes oder mehrstückiges Spritzgussbauteil ausgebildet sein. Sie weist vorzugsweise jedoch keine Verschraubungen oder andere abstehende Mittel auf, die zu Verletzungen führen könnten.The entire outer shape of the entire sports jacket is preferably covered by a plastic coating. The sports jacket can be designed as a single or multi-piece injection molded component. However, it preferably does not have any screw connections or other protruding means that could lead to injuries.

Es ist auch denkbar, dass die Sporthantel aus einem Gussteil, insbesondere Spritzgussbauteil, gefertigt ist oder aus zwei Spritzgussbauteilen in einer glatten Außenkontur zusammengefügt, insbesondere zusammengeklebt ist.It is also conceivable that the sports jacket is made from a cast part, in particular an injection-molded component, or from two injection-molded components joined together, in particular glued together, in a smooth outer contour.

Vorzugsweise weist der Griffabschnitt eine Daumenkerbe in Form einer Vertiefung auf, die der Hand des Sportlers zusätzlichen Halt gibt.The grip section preferably has a thumb notch in the form of a depression which gives the athlete's hand additional support.

Die Erfindung wird anhand eines Ausführungsbeispiels in sieben Figuren beschrieben. Dabei zeigen:

Die Figuren 1 - 4 zeigen eine Sporthantel in einer ersten Ausführungsform.The Figures 1 - 4 show a sports gown in a first embodiment.

Die in Fig. 1 dargestellte Sporthantel 1 weist einen Griffabschnitt 2 und einen Auflagenabschnitt 3 auf. Der Griffabschnitt 2 umfasst eine mittig entlang seiner Längsausdehnung angeordnete Griffachse L1. Der Griffabschnitt 2 ist dazu bestimmt, vom Sportler mit einer Hand umfasst zu werden. Dem Griffabschnitt 2 senkrecht zur Griffachse L1 gegenüberliegend ist der Auflagenabschnitt 3 angeordnet. Der Auflagenabschnitt 3 weist eine parallel zur Griffachse L1 angeordnete Auflagenachse L2 auf. Griffachse L1 und Auflagenachse L2 sind jeweils zentral durch die jeweiligen Abschnitte 2, 3 geführt.In the Fig. 1 The sports gown 1 shown has a grip section 2 and a support section 3. The handle section 2 comprises a handle axis L1 arranged centrally along its longitudinal extent. The grip section 2 is intended to be grasped by the athlete with one hand. The support section 3 is arranged opposite the handle section 2 perpendicular to the handle axis L1. The support section 3 has a support axis L2 arranged parallel to the handle axis L1. Grip axis L1 and support axis L2 are each guided centrally through the respective sections 2, 3.

Der Griffabschnitt 2 weist entlang seiner Griffachse L1 sich gegenüberliegend ein erstes Ende und ein zweites Ende auf, und der Auflagenabschnitt 2 weist ebenfalls entlang der Auflagenachse L2 sich gegenüberliegend ein erstes Ende und ein zweites Ende auf. Die jeweils ersten Enden sind über einen ersten bogenförmigen Verbindungsabschnitt 4 starr und positionsfest miteinander verbunden. Die beiden zweiten Enden sind ebenfalls über einen im Wesentlichen spiegelsymmetrisch zum ersten Verbindungsabschnitt 4 ausgebildeten zweiten Verbindungsabschnitt 5 starr und positionsfest miteinander verbunden. Ein Abstand d1 zwischen Innenwandungen des Griffabschnittes 2 und des Auflagenabschnittes 3 beträgt hier 6 cm. Es sind jedoch auch andere Größen denkbar. Ein Abstand d2 der Griffachse L1 und der Auflagenachse L2 beträgt zwischen 11 cm und 13 cm. Der Abstand d2 ist so bemessen, dass beim Greifen des Griffabschnittes 2 mit der Hand des Sportlers der Auflagenabschnitt 3 ellenbogenseitig des Handgelenkes auf seinem Unterarm aufliegt. Durch die Auflage des Gewichtes auf dem Unterarm wird das Handgelenk gegenüber herkömmlichen Hanteln deutlich weniger belastet, wenn Sportübungen durchgeführt werden.The handle section 2 has a first end and a second end opposite one another along its handle axis L1, and the support section 2 likewise has a first end and a second end opposite one another along the support axis L2. The respective first ends are rigidly and positionally connected to one another via a first arcuate connecting section 4. The two second ends are also connected to one another in a rigid and positionally fixed manner via a second connecting section 5, which is essentially mirror-symmetrical to the first connecting section 4. A distance d1 between the inner walls of the handle section 2 and the support section 3 is 6 cm here. However, other sizes are also conceivable. A distance d2 between the handle axis L1 and the support axis L2 is between 11 cm and 13 cm. The distance d2 is dimensioned so that when the athlete grips the grip section 2 with the hand of the athlete, the support section 3 rests on the elbow side of the wrist on his forearm. By placing the weight on the forearm, the wrist is significantly less stressed than conventional dumbbells when doing sports.

Ein Durchmesser D1 des Griffabschnittes 2 beträgt wenigstens 3 cm. Er ist hier entlang seiner gesamten Ausdehnung entlang der Griffachse L1 konstant. Ein Durchmesser D2 des Auflagenabschnittes 3 liegt zwischen 8,5 cm bis 11 cm. Er ist in der Ausführungsform in Fig. 1 entlang seiner gesamten Ausdehnung entlang der Auflagenachse L2 ebenfalls konstant.A diameter D1 of the handle section 2 is at least 3 cm. It is constant here along its entire extent along the handle axis L1. A diameter D2 of the support section 3 is between 8.5 cm and 11 cm. It is in the embodiment in Fig. 1 likewise constant along its entire extent along the support axis L2.

Die Gewichtsverteilung ist so bemessen, dass ein Schwerpunkt S der Sporthantel 1 in Richtung der Griffachse L1 mittig am Griffabschnitt 2 angeordnet ist, jedoch ist der Schwerpunkt S senkrecht zur Griffachse L1 nicht innerhalb des Griffabschnittes 2 angeordnet, sondern innerhalb des Auflagenabschnittes 3, so dass das Gewicht der Sporthantel bei Sportübungen eben nicht über die Handgelenke bewegt wird, sondern über die handseitigen Enden der Unterarme. Die Sporthantel 1 ist entlang einer senkrecht zur Griffachse L1 und Auflagenachse L2 angeordneten Spiegelebene im Wesentlichen spiegelsymmetrisch ausgebildet, um eine etwa mittige Positionierung entlang der Achsenrichtung zu ermöglichen.The weight distribution is such that a center of gravity S of the sports jacket 1 is arranged in the direction of the handle axis L1 centrally on the handle section 2, but the center of gravity S is not arranged perpendicular to the handle axis L1 within the handle section 2, but within the support section 3, so that The weight of the sports gown is not moved over the wrists during sports exercises, but over the hand-side ends of the forearms. The sports jacket 1 is designed to be essentially mirror-symmetrical along a mirror plane arranged perpendicular to the grip axis L1 and the support axis L2, in order to enable approximately central positioning along the axis direction.

Fig. 2 zeigt die Sporthantel 1 in Fig. 1 in einer perspektivischen Ansicht. Der entlang der Längsachse L1 ausgedehnte Griffabschnitt 3 weist an seinem ersten und zweiten Ende je einen Verbindungsabschnitt 4, 5 auf, das jeweils mit einem ersten und zweiten Ende des Griffabschnittes 2 verbunden ist. Griffabschnitt 2, Verbindungsabschnitte 4, 5 und Auflagenabschnitt 3 bilden eine geschlossen ringförmige Außenform aus, wobei unter Ring hier nicht eine streng kreisförmige äußere Form gemeint ist, sondern eine geschlossene Form mit einem Durchgriffsloch 7. Das Durchgriffsloch 7 ist zum Durchgreifen der Sportlerhand bestimmt. Fig. 2 shows the sports gown 1 in Fig. 1 in a perspective view. The handle section 3, which is extended along the longitudinal axis L1, has a connecting section 4, 5 at its first and second end, which is connected to a first and second end of the handle section 2. Grip section 2, connecting sections 4, 5 and support section 3 form a closed, ring-shaped outer shape, whereby the term ring here does not mean a strictly circular outer shape, but a closed shape with a penetration hole 7. The penetration hole 7 is intended for the athlete's hand to reach through.

Ein Querschnitt der Verbindungsabschnitte 4, 5 ist gleich und der des Auflagenabschnittes 3 ist senkrecht zur Umfangsrichtung im Wesentlichen auch gleichbleibend, ein Querschnitt des Griffabschnittes 2 entlang und senkrecht zur Umfangsrichtung ist mit 3 cm im Durchmesser D1 deutlich kleiner als der Durchmesser D2 des Auflagenabschnitts 3. Der Durchmesser D2 des Auflagenabschnitts 3 beträgt zwischen 8,5 cm bis 11 cm. Die äußeren Maße der Sporthantel betragen in Fig. 2 in Richtung der Griffachse L1 bzw. Auflagenachse L2 28 cm bis 30 cm und senkrecht zur Griffachse 17,5 cm bis 20 cm.A cross section of the connecting sections 4, 5 is the same and that of the support section 3 is also essentially constant perpendicular to the circumferential direction, a cross section of the handle section 2 along and perpendicular to the circumferential direction is 3 cm in diameter D1, significantly smaller than the diameter D2 of the support section 3. The diameter D2 of the support section 3 is between 8.5 cm and 11 cm. The outer dimensions of the sports gown are in Fig. 2 28 cm to 30 cm in the direction of the handle axis L1 or support axis L2 and 17.5 cm to 20 cm perpendicular to the handle axis.

Die Figuren 3a bis 3c zeigen die Griffhaltung eines Sportlers zur Durchführung von Sportübungen. 3b zeigt die Sporthantel 1 der Fig. 1, die vom Sportler am Griffabschnitt 2 gegriffen wird. Der Auflagenabschnitt 3 liegt auf der Außenhandseite des Unterarmes auf, wobei der Auflagepunkt des Griffabschnitts 2 armseitig des Handgelenkes liegt. Der Schwerpunkt S der gesamten Sporthantel 1 liegt ebenfalls im Inneren des Auflagenabschnitts 3, so dass beim Bewegen des Armes der Angriffspunkt der Kraft armseitig des Handgelenkes vorgesehen ist und damit keine übermäßige Beanspruchung des Handgelenkes stattfindet.The Figures 3a to 3c show the grip position of an athlete for performing sports exercises. 3b shows the sports gown 1 of Fig. 1 that is gripped by the athlete at the grip section 2. The support section 3 rests on the outer hand side of the forearm, the support point of the grip section 2 being on the arm side of the wrist. The center of gravity S of the entire sports jacket 1 is also located inside the support section 3, so that when the arm is moved, the point of application of the force is provided on the arm side of the wrist and thus there is no excessive stress on the wrist.

Fig. 3b und 3c zeigen eine Griffhaltung der Sporthantel 1 bei geöffneter Hand; einmal in einer Ansicht vorderhändig und einmal in einer Ansicht rückhändig. Figures 3b and 3c show a grip position of the sports gown 1 with an open hand; once in a front-handed view and once in a back-handed view.

Fig. 4 zeigt eine zweite Ausführungsform der erfindungsgemäßen Sporthantel 1, wobei an den Verbindungsabschnitten 4, 5 (nicht eingezeichnete) Ösen vorgesehen sind, an deren Enden ein elastisches und/oder längenverstellbares Band 8 angeordnet ist, und die Sporthantel kann daher hinter der Ferse des Sportlers gehalten werden, wenn der Sportler den Fuß durch die Durchgriffsöffnung 7 der Sporthantel steckt. Es können dann auch Kräftigungs- und Sportübungen mit den Beinen durchgeführt werden. Fig. 4 shows a second embodiment of the sports jacket 1 according to the invention, with eyelets (not shown) being provided on the connecting sections 4, 5, at the ends of which an elastic and / or length-adjustable band 8 is arranged, and the sports jacket can therefore be held behind the athlete's heel when the athlete puts his foot through the opening 7 of the sports gown. Strengthening and sports exercises can then also be carried out with the legs.

Fig. 5 zeigt eine zweite Ausführungsform der erfindungsgemäßen Sporthantel 1. Gleiche Bezugszeichen bedeuten gleiche Merkmale. Die Sporthantel 1 weist einen Griffabschnitt 2 und einen Auflagenabschnitt 3 auf, die wie in der ersten Ausführungsform ausgeformt sein können. Im Gegensatz zur ersten Ausführungsform ist zwischen dem Griffabschnitt 2 und dem Auflagenabschnitt 3 lediglich der zweite Verbindungsabschnitt 5 vorgesehen, der den Griffabschnitt 2 und den Auflagenabschnitt 3 positionsfest relativ zueinander hält. Ein erster Verbindungsabschnitt 4 existiert nicht. Die Sporthantel 1 ist an dem ersten Ende offen. Die Sporthantel 1 ist daher in einem Querschnitt in der durch die Griffachse L1 und die Auflagenachse L2 gebildeten Ebene nicht ringförmig wie in der ersten Ausführungsform, sondern im Wesentlichen U-förmig ausgebildet. Der Schwerpunkt S ist innerhalb des Auflagenabschnitts 3 angeordnet. Fig. 5 shows a second embodiment of the sports jacket 1 according to the invention. The same reference symbols denote the same features. The sports gown 1 has a grip section 2 and a support section 3, which can be shaped as in the first embodiment. In contrast to the first embodiment, only the second connecting section 5 is provided between the handle section 2 and the support section 3, which holds the handle section 2 and the support section 3 in a fixed position relative to one another. A first connection section 4 does not exist. The sports gown 1 is open at the first end. The sports jacket 1 is therefore not annular in a cross section in the plane formed by the grip axis L1 and the support axis L2, as in the first embodiment, but is essentially U-shaped. The center of gravity S is arranged within the support section 3.
