Abstract

The infinitely adjustable muscle training machine (1-15) with metal weights has an invariable weight block which is moved up and down on a guide rail with adjustable incline by the operator. The force resulting from the weight can be set by altering the incline of the guide rail. The weight can be moved actively by the person training through rotating chain drives in both directions in order to prevent knocking of the chains. USE/ADVANTAGE - Muscle training machine. Since energy is only required to adjust the load and not maintain same less energy is required. The load last set is maintained even if the current fails.

Description

Die Erfindung betrifft eine stufenlos regelbare Kafttrainingsmaschine mit Metallgewichten.The invention relates to a continuously adjustable kaft training machine with metal weights.

Um ein optimales Training zu ermöglichen, soll die vom Trainierenden zu bewegende Last möglichst genau einstellbar sein. Viele Trainings­ techniken erfordern eine häufige Neueinstellung der Last. Im Rehabili­ tationsbereich können sogar, z. B. nach Muskelrissen Lastveränderungen während einer einzelnen Bewegung erforderlich sein, um geschädigte Muskelpartien zu schonen. Außerdem wird das Training effektiver, wenn sich die Last bei fortschreitender Muskelermüdung stetig vermindert, weil so die Belastungsdauer erhöht werden kann.In order to enable optimal training, that of the exerciser load to be moved can be adjusted as precisely as possible. Many trainings techniques require frequent load readjustments. In the rehabilitation center tationsbereich can even, for. B. after muscle tears load changes to be damaged during a single move To protect muscles. Training will also be more effective if the load decreases steadily with increasing muscle fatigue, because it can increase the duration of exposure.

Es sind Krafttrainingsmaschinen bekannt, die diese Anforderungen er­ füllen, indem der Trainierende gegen die Kraft eines hydraulischen, pneumatischen oder elektromagnetischen Systems arbeitet. Hierbei wird im Fall der hydraulischen und pneumatischen Systeme mittels einer Pumpe Druck in einem Zylinder erzeugt, dessen Kolben vom Trainierenden bewegt wird. Bei den elektromagnetischen Systemen wird ein starkes Drehmoment erzeugt, entweder durch einen über Wirbelstrombremsen ge­ koppelten Motor oder ein magnetisches Drehfeld.Strength training machines are known to meet these requirements by training against the force of a hydraulic, pneumatic or electromagnetic system works. Here will in the case of hydraulic and pneumatic systems using a Pump generates pressure in a cylinder, the piston of which is exercised is moved. With electromagnetic systems, a strong one Torque generated, either by a via eddy current brakes coupled motor or a rotating magnetic field.

Bei hydraulischen bzw. pneumatischen Systemen verändert sich die zum Bewegen des Kolbens erforderliche Kraft in Abhängigkeit zur bereits zurückgelegten Wegstrecke. Um diese Veränderungen zu neutralisieren sind Exzentertriebe erforderlich, die in der Herstellung recht teuer sind. Bei den elektromagnetischen Systemen besteht ein hoher Energie­ bedarf, da nicht nur zum Einstellen, sondern auch zum Aufrechterhalten der Last Strom verbraucht wird.In hydraulic or pneumatic systems, this changes to Moving the piston required force depending on the already distance traveled. To neutralize these changes eccentric drives are required, which are quite expensive to manufacture are. There is high energy in the electromagnetic systems needs, because not only to adjust, but also to maintain the load is consuming electricity.

Da ein Stromausfall zum schlagartigen Abfall der Last führt, sind Sicherheitsbremsen erforderlich, um Verletzungen des Trainierenden zu verhindern.Since a power failure leads to a sudden drop in the load Safety brakes required to prevent injuries to the exerciser prevent.

Der Erfindung liegt die Aufgabe zugrunde, die Last einer Krafttrai­ ningsmaschine auf eine Weise bereitzustellen und zu regeln, die die Nachteile der bestehenden Systeme ausschaltet.The invention has for its object the load of a power train ningsmaschine in a way that regulates the Eliminates disadvantages of the existing systems.

Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This task is performed in a generic device by the characterizing features of claim 1 solved.

Um ein Schlagen der Antriebskette zu verhindern, welches im unteren Lastbereich dadurch entstehen könnte, daß das Gewicht langsamer zu­ rückläuft als z. B. der vom Trainierenden bewegte Hebel oder Zuggriff, ist das System mit umlaufenden Kettentrieben versehen, welche ein ak­ tives Bewegen des Gewichts in beiden Richtungen ermöglichen.To prevent the drive chain from beating, which is in the lower Load area could arise due to the weight becoming slower returns as z. B. the lever or pull handle moved by the exerciser, the system is provided with revolving chain drives, which an ak Enable weight to be moved in both directions.

Die mit der Erfindung erzielten Vorteil liegen zum einen im niedrigen Energieverbrauch, da nur zum Einstellen, nicht aber zum Aufrechterhal­ ten der Last Energie benötigt wird, zum anderen in der hohen Sicher­ heit, da die zuletzt eingestellte Last auch dann erhalten bleibt, wenn einmal der Strom ausfällt oder eine Störung auftritt.The advantages achieved by the invention are low Energy consumption, since only for adjustment, but not for maintenance most of the load energy is required, on the other hand in the high security because the last set load is retained even if once the power fails or a malfunction occurs.

Ein weiterer Vorteil liegt in der leichten Herstellbarkeit, da aus­ schließlich Normteile und -halbzeuge nach DIN verwendet werden. Another advantage lies in the fact that it is easy to manufacture finally standard parts and semi-finished products according to DIN are used.  

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung darge­ stellt und wird im folgenden näher beschrieben:An embodiment of the invention is shown in the drawing represents and is described in more detail below:

Ein auf Rollen (1) gelagertes, aus rechteckigen Metallplatten beste­ hendes Gewicht (2) bewegt sich entlang der aus einem Vierkantrohr gefertigten Fühungsschiene (5). Der Antrieb erfolgt durch eine umlau­ fende Kette (4), an der das Gewicht mit einem Bolzen (3) befestigt ist. Die Kette läuft um das obere Ritzel (6) herum, durch das Vier­ kantrohr der Führungsschiene hindurch und um das erste Ritzel des auf einer gemeinsamen Welle (9) verdrehsicher befestigten Ritzelpaares (7). Vom zweiten Ritzel kann nun die Kraft des Gewichtes in Form eines Drehmoments abgenommen werden. Im gezeichneten Beispiel erfolgt eine Übertragung über eine Endloskette (11) auf ein anderes Ritzel (12), an dem z. B. ein vom Trainierenden zu drückender Hebel befestigt werden kann.A weight ( 2 ) mounted on rollers ( 1 ) and consisting of rectangular metal plates moves along the guide rail ( 5 ) made from a square tube. The drive is carried out by a circumferential chain ( 4 ), to which the weight is attached with a bolt ( 3 ). The chain runs around the upper sprocket ( 6 ), through the square tube of the guide rail and around the first sprocket of the pair of sprockets ( 7 ) secured against rotation on a common shaft ( 9 ). The force of the weight can now be taken from the second pinion in the form of a torque. In the example shown, transmission takes place via an endless chain ( 11 ) to another sprocket ( 12 ), on which, for. B. a lever to be pressed by the exerciser can be attached.

Zwei Anschläge (10) begrenzen den Bewegungsraum des Gewichts. Die Neigung der Führungsschiene und damit die wirkende Kraft bzw. Last wird über ein Zugseil (13) verändert, welches von einer Elektrowinde (14) auf- bzw. abgewickelt wird. Der Drehpunkt der Führungsschiene ist identisch mit dem Drehpunkt des Ritzelpaares (7).Two stops ( 10 ) limit the range of motion of the weight. The inclination of the guide rail and thus the acting force or load is changed via a pull rope ( 13 ) which is wound up or unwound by an electric winch ( 14 ). The pivot point of the guide rail is identical to the pivot point of the pinion pair ( 7 ).

Dessen gemeinsame Welle dreht sich um einen Bolzen (8), mit dem die gesamte Anordnung auf einem Befestigungsflansch (15) gelagert ist. Mit diesem Befestigungsflansch wird die Anordnung mit dem Rahmen der Krafttrainingsmaschine verbunden.Its common shaft rotates around a bolt ( 8 ) with which the entire arrangement is mounted on a mounting flange ( 15 ). With this mounting flange, the arrangement is connected to the frame of the strength training machine.
