Abstract

A dry-training apparatus for simulating crawl swimming movements includes deflection rollers and a braking device for the deflection rollers. An endless traction member guided over the deflection rollers has an endless belt of hard elastic material with a surface, a lower strand, and an upper strand that can sag elastically toward the lower strand. A supporting element is disposed above the traction member. At least three handles are firmly joined to the surface of the revolving belt for moving the traction member in alternation by two hands of a user located on the supporting element. The handles are disposed at a mutual spacing causing a resting and synchronizing phase to necessarily ensue between two exertions of force on successive handles, in which phase the traction member moves onward solely by its moment of inertia.

Description

Die Erfindung betrifft ein Trocken-Trainingsgerät zur Simulation des Bewegungsablaufs beim Kraulschwimmen, mit einem über eine Bremseinrichtung aufweisende Umlenkrollen geführten endlosen Zugorgan mit mehreren daran im Abstand zueinander angebrachten Griffelementen zur Bewegung des Zugorgangs im Wechsel der beiden Hände eines auf einem oberhalb des Zugorgans angeordneten Auflageelement befindlichen Benutzers.The invention relates to a dry training device for Simulation of the sequence of movements during crawl swimming, with a pulley having a braking device guided endless traction element with several attached to it at a distance mutually attached handle elements for moving the Train alternating two hands one on one arranged above the tension member support element located user.

Aus der DE 42 18 478 A1 ist bereits eine Vorrichtung zum Muskeltraining für Schwimmer und insbesondere zur Nachbildung einer Kraulbewegung bekannt, bei der vor dem auf einer Auflagefläche liegenden Benutzer zwei in spitzem Winkel aufeinanderzulaufende, viertelkreisförmige, um jeweils zwei Umlaufpunkte geführte Zugorgane angeordnet sind. Die Zugorgane sind mit einer Belastungseinrichtung versehen, um deren Bewegung durch die Arme des Benutzers eine Widerstandskraft entgegenzusetzen. Sie bestehen aus jeweils zwei nebeneinander angeordneten, durch eine Vielzahl von aufeinanderfolgenden Griffen verbundenen Ketten oder Bändern, die im Ober- und Untertrum auf verstellbaren, viertelkreisförmig angeordneten Tragrollen abgestützt sind.DE 42 18 478 A1 already describes a device for Muscle training for swimmers and especially for Replica of a crawl movement known in which before users lying on a support surface two in acute angle, quarter circle, around two points of rotation guided traction elements are arranged. The traction elements are provided with a loading device to their Movement through the user's arms To oppose resistance. they consist of two each next to each other, by one Variety of consecutive handles connected Chains or bands that are in the upper and lower run adjustable, quarter-circle arranged idlers are supported.

Mit diesem Trocken-Trainingsgerät für das Kraulschwimmen ist es zwar möglich, speziell bei dieser Schwimmart beanspruchte Muskelpartien zu stärken, jedoch lassen sich die Widerstandskräfte bei der Bewegung eines Schwimmers im Wasser, die zudem von der Schwimmgeschwindigkeit abhängen, mit dieser Vorrichtung nicht nachbilden. Durch die abwechselnde Betätigung des einen oder des anderen Zugorgans, muß dieses immer wieder aus einem annähernden Ruhezustand in Bewegung gesetzt werden, so, als ob der Schwimmer bei jedem Armzug erneut zu schwimmen beginnt. Dadurch sind Überbelastungen der Muskulatur und der Gelenke nicht auszuschließen. Insofern ist das Gerät auch nicht zur exakten Nachbildung des Kraulens oder zum Erlernen und Trainieren des Kraulens geeignet, da es dem Benutzer überlassen bleibt, wann er mit dem nächsten Armzug einsetzt und an welcher Stelle des dicht mit Griffelementen besetzten Zugorgans er damit beginnt. Zudem entspricht die mit diesem Trainingsgerät ausführbare Bewegung mit immer gestrecktem Arm nicht der tatsächlichen Armhaltung beim Kraulschwimmen.With this dry training device for crawl swimming it is possible, especially with this type of swimming Strained muscle areas to be strengthened, however the resistance forces when moving a swimmer in the water, which also depends on the swimming speed depend, do not simulate with this device. By the alternating actuation of one or the other Zugorgans, this must always come from an approximate Be put into motion as if the The swimmer starts swimming again with each stroke. This causes overloading of the muscles and the Joints cannot be excluded. In this respect, the device is also not for the exact replica of the crawl or for Learn and train the crawl suitable because it is User is left with when to switch to the next Arm pull starts and at which point of the tight with Handle elements occupied train organ he begins. It also corresponds to this training device executable movement with the arm always stretched not the actual arm posture when crawling.

Auch mit dem in der SU-PS 597 376 beschriebenen Kraulschwimm-Trainingsgerät, das, wie ein Förderband, aus einem endlosen Zugorgan mit geradem Obertrum gebildet ist, kann die tatsächliche Bewegungsbahn der Arme beim Kraulschwimmen, bei dem bekanntlich die jeweilige Hand während ihrer Kraftwirkung im Wasser in einem langen halben Oval unterhalb des Körpers geführt ist, nicht nachgebildet werden. Zudem liegt auch bei diesem Gerät die Koordinierung des Bewegungsablaufs beider Arme oder die Frequenz der Armbewegungen im Ermessensbereich des Trainierenden, der das Band an beliebiger Stelle und in beliebigen Zeitintervallen antreibt.Also with that described in SU-PS 597 376 Freestyle swimming training device that, like a conveyor belt an endless traction element with a straight upper run the actual path of movement of the arms during Freestyle swimming, which is known to involve the respective hand during their action in the water in a long half oval below the body is not be replicated. Also lies with this device the coordination of the movement of both arms or the frequency of arm movements within the discretionary range of the Exerciser who the tape anywhere and in drives any time intervals.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Trocken-Trainingsgerät der eingangs erwähnten Art so auszubilden, daß ein den tatsächlichen Verhältnissen beim Kraulen im Wasser nahekommender Bewegungsablauf und eine mit dem Kraulschwimmen weitestgehend übereinstimmende Kraftwirkung auf den menschlichen Körper erreicht wird.The invention is therefore based on the object Dry training device of the type mentioned above to train that a the actual conditions at Crawl in the water and a movement sequence that comes close largely coinciding with the crawl swimming Effect of force on the human body is achieved.

Erfindungsgemäß wird die Aufgabe bei einem Trocken-Trainingsgerät gemäß dem Oberbegriff des Patentanspruchs 1 in der Weise gelöst, daß das Zugorgan aus einem endlosen, im Obertrum zum Untertrum hin elastisch durchbiegbaren Band aus hartelastischem Material gebildet ist und der gegenseitige Abstand der mindestens drei mit der Oberfläche des umlaufenden Bandes fest verbundenen Griffelemente so gewählt ist, daß zwischen zwei Krafteinwirkungen auf aufeinanderfolgende Griffelemente zwangsläufig eine Ruhe- oder Synchronisierphase eintritt, in der sich das Zugorgan allein aufgrund seines Trägheitsmoments weiterbewegt.According to the invention, the task with a dry training device according to the preamble of claim 1 in solved in such a way that the traction element from an endless, elastically bendable in the upper run towards the lower run Band is made of hard elastic material and the mutual distance of the at least three with the surface of the circumferential band firmly connected grip elements is chosen so that between two forces successive handle elements inevitably a resting or Synchronization phase occurs in which the tension member moved on solely due to its moment of inertia.

Durch die Ausbildung des Zugorgans als elastisches, im Obertrum nicht abgestütztes und nach unten durchbiegbares Band werden die Kraft- und Bewegungsverhältnisse im Wasser am besten nachgeahmt, indem die jeweilige Handfläche sowohl den Druck in Schwimmrichtung als auch senkrecht dazu zu überwinden hat und während ihrer Kraftwirkung in einer etwa einem halben Längsoval entsprechenden, relativ dicht unter dem Körper verlaufenden Kurve geführt wird.By training the tension member as an elastic, in Upper run not supported and bendable downwards The strength and movement relationships in the band Water is best mimicked by each Palm both the pressure in the swimming direction as well has to overcome perpendicular to it and during their Effect of force in about half a longitudinal oval corresponding, relatively close under the body extending curve is performed.

Das Wesen der Erfindung ist zum anderen durch die Anordnung der Griffelemente in einem Abstand geprägt, der dem Benutzer den Rhythmus seiner Armbewegungen gleichsam vorgibt.The essence of the invention is due to the other Arrangement of the handle elements embossed at a distance that the rhythm of his arm movements, as it were pretends.

Die Krafteinwirkung auf das Band erfolgt dabei infolge des gewählten Abstands der Griffelemente nicht in unmittelbarer und nicht frei wählbarer Aufeinanderfolge, sondern zwischen zwei Krafteinwirkungen auf das Band bzw. auf aufeinanderfolgende Griffelemente verbleibt eine bestimmte Ruhephase oder Synchronisierphase, in der die Führungshand in Ruhestellung verharrt und das nächste Griffelement erwartet. In diesem Zeitraum wird das Zugorgan somit nicht angetrieben, sondern bewegt sich bei geringem Geschwindigkeitsabfall allein aufgrund der Trägheitskraft, die über den Reibungs- und Bremskräften liegt, weiter.The force exerted on the belt occurs as a result the selected distance of the handle elements not in immediate and not freely selectable sequence, but between two forces acting on the belt or one remains on successive handle elements certain resting phase or synchronization phase in which the The leadership hand remains at rest and the next Handle element expected. During this period it will The traction element is therefore not driven, but moves low speed drop solely due to the Inertia, which is above the friction and braking forces lies, further.

Durch die wirklichkeitsnahe Simulation des Kraulschwimmens ist das vorgeschlagene Gerät mithin sowohl im Bereich des allgemeinen körperlichen Trainings als auch der physiotherapeutischen Behandlung anwendbar und bewirkt aufgrund dynamischer Kraftwirkungen einen proportionalen Muskelaufbau. Andererseits ist es auf dem Gebiet der speziellen sportlichen Betätigung zum einen für den Ausgleichssport, beispielsweise für Feder- und Volleyballspieler, geeignet. Ein spezifisches Anwendungsgebiet ist schließlich das spezielle Kraulschwimm-Trockentraining, da zum einen die Verhältnisse im Wasser annähernd genau nachgeahmt werden und zum anderen dem Trainierenden ein Bewegungsablauf, d. h. eine Bewegung der Arme und des Oberkörpers und ein Bewegungsrhythmus, vorgegeben wird, der ihn zum Erlernen und Trainieren des besonderen Kraulbewegungsablaufs - bis zum Erreichen höchster körperlicher Leistungen - befähigt.Through the realistic simulation of the The proposed device is therefore crawl swimming both in the field of general physical training as well as the physiotherapeutic treatment and causes one due to dynamic force effects proportional muscle building. On the other hand, it is on the Field of special sporting activity on the one hand for the balance sport, for example for feather and Volleyball player, suitable. A specific one After all, the area of application is the special one Freestyle swimming dry training, because on the one hand Conditions in water can be mimicked almost exactly and on the other hand a movement sequence for the exerciser, d. H. a movement of the arms and upper body and a Rhythm of movement, which is given to him for learning and training the special crawl movement - until to achieve the highest physical performance - capable.

Weitere Merkmale und zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen aufgeführt. Other features and appropriate training of Invention are listed in the subclaims.

Ein Ausführungsbeispiel der Erfindung wird anhand der Zeichnung in einer einzigen Figur, in der ein erfindungsgemäßes Trocken-Trainingsgerät zur Nachbildung des Bewegungsablaufs beim Kraulschwimmen in einer Seitenansicht schematisch dargestellt ist, näher erläutert.An embodiment of the invention is based on the Drawing in a single figure, in the one Dry training device according to the invention for replication the sequence of movements in crawl swimming in one Side view is shown schematically, closer explained.

Das Trocken-Trainingsgerät umfaßt als wesentliche Bestandteile ein Rahmengestell 1 mit einem auf diesem höhenverstellbar (Pfeil A) und in Längsrichtung winkelveränderlich (Pfeil B) angeordneten Auflageelement 2 sowie einem endlosen, umlaufenden Zugorgan 3. Das Auflageelement 2 ist mit Polsterteilen 2a aus Schaumstoff oder einer wasser- bzw. luftgefüllten Umhüllung versehen. Auf dem Auflageelement 2 befindet sich in Gebrauchsstellung eine (hier nicht dargestellte) trainierende Person in Bauchlage. Das Auflageelement 2 weist einen auskragenden Teil 2b auf, dessen Ende etwa bis zur Mitte des Zugorgans 3 reicht. Das Zugorgan besteht aus einem endlosen Band 4 aus hartelastischem Material, das über Umlenkrollen 5, 6 geführt ist. Die Breite des Bandes entspricht etwa der einer menschlichen Hand.The dry exercise machine includes essentials Components a frame 1 with one on this adjustable in height (arrow A) and lengthways adjustable support element (arrow B) 2 as well as an endless, revolving traction element 3 Support element 2 is made of foam with cushion parts 2a or a water- or air-filled envelope. On the support element 2 is in Use position one (not shown here) exercising person in prone position. The support element 2 has a cantilevered part 2b, the end of which extends to the middle of the train organ 3. The train organ consists of an endless band 4 made of hard elastic Material that is guided over pulleys 5, 6. The The width of the band corresponds approximately to that of a human Hand.

Die Umlenkrollen 5, 6 sind am Rahmengestell 1 an in Längsrichtung verstellbaren (Pfeil C) Stegen 7, 8 gelagert, wobei die unterhalb des Auflageelements 2 befindliche erste Umlenkrolle 5 in einer senkrechten Führung 7a höhenverstellbar (Pfeil D) im Steg 7 angeordnet ist und die zweite Umlenkrolle 6 in einer waagerechten Führung 8a in Längsrichtung verstellbar (Pfeil E) angeordnet ist und somit als Spannrolle dient. The pulleys 5, 6 are on the frame 1 in Longitudinally adjustable (arrow C) webs 7, 8 stored, the below the support element 2 located first pulley 5 in a vertical Height-adjustable guide 7a (arrow D) in web 7 is arranged and the second deflection roller 6 in one horizontal guide 8a adjustable in the longitudinal direction (Arrow E) is arranged and thus serves as a tension roller.

An der zweiten Umlenkrolle 6 ist ein Bremsband 9 angeordnet und über eine Spannfeder 10 und ein Spannelement 11 mit dem Rahmenteil 1 verbunden. Auf dem umlaufenden Band 4 befinden sich drei von dessen Oberfläche abstrebende, in gleichmäßigem Abstand zueinander angeordnete Griffelemente 12.There is a brake band 9 on the second deflection roller 6 arranged and a tension spring 10 and a Clamping element 11 connected to the frame part 1. On the revolving band 4 are three of its Surface striving, evenly spaced grip elements 12 arranged relative to one another.

Zur Durchführung des Trockenkraultrainings liegt der Benutzer bäuchlings auf den Posterteilen 2a des Auflageelements 2. Durch die Höhenlage des Auflageelements 2 und dessen Schrägstellung sowie die Winkelstellung des Zugorgans 3 ist eine derartige Einstellung des Benutzers zum Band 4 möglich, daß er mit einer Hand ein Griffelement hinter der zweiten Umlenkrolle 6 erfassen und das Obertrum des Bandes 4 aufgrund dessen Elastizität und Durchhanges längs einer kurvenförmigen Bahn, die auch der Handbewegung beim Kraulen im Wasser entspricht, bewegen kann.To carry out the dry crawl training lies the Users face down on the poster parts 2a of the Support element 2. Due to the height of the Support element 2 and its inclination and the Angular position of the pulling element 3 is such Attitude of the user to volume 4 possible that he with one hand a grip element behind the second Detect the pulley 6 and the upper run of the belt 4th due to its elasticity and sag along one curved path, which is also the hand movement when Crawling in the water corresponds, can move.

Die Ebene des Auflageelements 2 ist zur Ebene des Laufbandes 4 in einem Winkel von α = 0 bis 30° sowie in der Höhe einstellbar, so daß dadurch eine Anpassung an die jeweilige Körperform - zum Beispiel Armlänge - des Benutzers vorgenommen werden kann. Die Länge und Elastizität des Bandes 4 ist so gewählt, daß zum einen eine ausreichende Durchbiegung des Bandes mit der auf ein Griffelement einwirkenden Krafthand möglich ist. Andererseits ist das Band aber derart steif, daß es bei der Krafteinwirkung auf ein Griffelement 12 nicht senkrecht durchgebogen oder abgeknickt wird. Die Durchbiegung des Bandes 4 kann im übrigen auch mit der durch die waagerechte Führung 8a im Steg 8 gegebenen Spannmöglichkeit über die zweite Umlenkrolle 6 geregelt werden. The level of the support element 2 is at the level of Treadmill 4 at an angle of α = 0 to 30 ° and in the height adjustable, so that an adjustment to the respective body shape - for example arm length - of User can be made. The length and Elasticity of the band 4 is chosen so that on the one hand Adequate deflection of the band with the on Grip element acting force hand is possible. On the other hand, the tape is so stiff that it is the force acting on a grip element 12 is not is bent or bent vertically. The Deflection of the band 4 can also with the given by the horizontal guide 8a in the web 8 Clamping possibility regulated via the second deflection roller 6 will.

Durch die Länge des Zugorgans wird andererseits der Abstand der Griffelemente 12 in der Weise festgelegt, daß nach Ausführung eines Armzuges die andere Hand (Führungshand des Kraulschwimmers) bereits in Wartestellung liegt und nach einer kurzen Synchronisierphase, in der das Zugorgan 3 aufgrund der Rotationsenergie der Umlenkrollen 5, 6 und der kinetischen Energie des Bandes 4 noch nicht zur Ruhe gekommen ist, d. h. ein nur unwesentliches Absinken der Bandgeschwindigkeit zu verzeichnen ist, nunmehr diese Hand, die jetzt zur Krafthand wird, die Weiterbewegung des Bandes 4 übernimmt.On the other hand, the length of the tension member Distance of the handle elements 12 set in such a way that after performing an arm pull the other hand (Leading hand of the crawl swimmer) already in Waiting position and after a short Synchronization phase in which the tension member 3 due to Rotational energy of the pulleys 5, 6 and kinetic energy of band 4 is not yet at rest has come d. H. an insignificant drop in the Belt speed is recorded, now this Hand, which now becomes a force hand, the further movement of volume 4 takes over.

Auf diese Weise lassen sich Bewegungsabläufe der Arme und des Oberkörpers des Benutzers sowie Kräfteverhältnisse einstellen, die mit denen der Bewegung eines Schwimmers im Wasser im wesentlichen übereinstimmen bzw. diesen doch sehr nahe kommen. Dem Übenden wird durch die Synchronisierphase, in der die Führungshand in Wartestellung verbleibt, auch ein den tatsächlichen Verhältnissen beim Kraulschwimmen entsprechender gleichmäßiger Rhythmus vorgegeben. Dadurch wird auch ein Lern- und Übungseffekt hinsichtlich der Kraultechnik erzielt. Bei vorbestimmter Gleichmäßigkeit der Armbewegungen, d. h. einem gleichmäßigen Wechsel zwischen Führungshand und Krafthand, kann die Bewegungsfrequenz dennoch durch den Übenden beeinflußt werden. Eine Überlastung der Muskeln, Bänder und Gelenke ist aber aufgrund der Nachbildung der Kräfteverhältnisse bei einem sich im Wasser fortbewegenden Körper nicht zu befürchten.In this way, movements of the arms and of the user's upper body and balance of power adjust that with those of a swimmer's movement in the water essentially match or do come very close. The practitioner is Synchronization phase, in which the management hand in The waiting position remains, even the actual one Corresponding conditions for crawl swimming regular rhythm. This also becomes a Learning and practice effect regarding the crawl technique achieved. With predetermined uniformity of Arm movements, d. H. an even change between Leading hand and strength hand, the movement frequency nevertheless be influenced by the practitioner. A However, the muscles, ligaments and joints are overloaded due to the simulation of the balance of power in one not to fear body moving in water.

Die Größe der Umlenkrollen 5, 6 ist so festgelegt, daß keine störenden Kräfte zwischen dem umlaufenden Band 4 und den Umlenkrollen 5, 6 auftreten. Vorzugsweise beträgt der Rollendurchmesser d mindestens 15 cm. Andererseits wird die Länge der Synchronisierphase, d. h. der Wartephase der Führungshand oder der nichtangetriebenen Phase des Bandes, durch die Größe des Rollendurchmessers d und den Abstand Δ zwischen den Griffelementen 12 bestimmt. Das Verhältnis zwischen dem Rollendurchmesser d und dem Griffelementeabstand Δ liegt zwischen 1:7 und 1:9. Schließlich darf aber das Trägheitsmoment des aus Umlenkrollen 5, 6 und umlaufendem Band 4 bestehenden Systems einen bestimmten Wert nicht unterschreiten, damit das Zugorgan in der Synchronisierphase, in der es nicht angetrieben wird, nicht zum Stillstand kommt. Ein Geschwindigkeitsabfall bis zu 10% kann jedoch in kauf genommen werden.The size of the guide rollers 5, 6 is determined so that no disruptive forces between the circulating belt 4 and the deflection rollers 5, 6 occur. Preferably is the roll diameter d at least 15 cm. On the other hand the length of the synchronization phase, i.e. H. of the Waiting phase of the management hand or the non-powered one Phase of the belt, by the size of the roll diameter d and the distance Δ between the grip elements 12 certainly. The ratio between the roll diameter d and the grip element distance Δ is between 1: 7 and 1: 9. Finally, the moment of inertia of the Deflecting rollers 5, 6 and circumferential belt 4 existing Systems do not fall below a certain value so the tension member in the synchronization phase, in which it is not is driven, does not come to a standstill. A However, speed drop of up to 10% can be purchased be taken.

Im Ausführungsbeispiel ist ein Band 4 mit drei in gleichem Abstand angeordneten Griffelementen 12 vorgesehen. Es ist natürlich auch denkbar, mehr als drei Griffelemente anzuordnen. Damit wird die Länge des Zugorgans 3, aber auch sein Platzbedarf, erhöht.In the exemplary embodiment, a band 4 with three in Handle elements 12 arranged at the same distance intended. Of course, it is also conceivable to have more than three Arrange handle elements. So that the length of the Zugorgans 3, but also its space requirements increased.

Andererseits ist es möglich, neben einem Band 4 mit einer für den überwiegenden Teil der Benutzer geeigneten Standardlänge noch eine größere oder geringere Bandlänge für Personen mit wesentlich kleinerer oder größerer Körperhöhe einzusetzen. Vorzugsweise können derartige Bänder auch verlängerbar ausgebildet sein.On the other hand, it is possible to use a tape 4 with a suitable for the majority of users Standard length even a larger or shorter band length for people with much smaller or larger Body height. Preferably, such Tapes can also be designed to be extendable.

Es hat sich im übrigen herausgestellt, daß der Trainingseffekt auch bei einem umlaufenden Band geringer Breite, beispielsweise von 10 cm, ohne weiteres erreicht wird, so daß sich der Raumbedarf auch diesbezüglich in Grenzen hält. It has also been found that the Training effect less even with a circulating belt Width, for example of 10 cm, easily reached is, so that the space requirement in this regard Limits.

Die Größe der bei einer Armbewegung zur Betätigung des Zugorgans aufzubringenden Kraft wird entsprechend der für eine gedachte Bewegung im Wasser angenommenen Geschwindigkeit von 1.5 m/s auf eine dementsprechende Widerstandskraft von 10 bis 15 kp eingestellt. Bei einer Erhöhung der Frequenz der Armbewegungen am Trocken-Trainingsgerät wird eine Erhöhung der Schwimmgeschwindigkeit simuliert, bei der sich entsprechend den Bewegungsverhältnissen im Wasser die Kraftwirkung an den Armen relativ verringert.The size of the arm movement to operate the Zugorgans force to be applied according to the for assumed movement in water Speed of 1.5 m / s on a corresponding Resistance of 10 to 15 kp set. At a Increase the frequency of arm movements on the dry training device will increase the Swimming speed simulated at which according to the movement conditions in the water The effect of strength on the arms is relatively reduced.
