Description

Stufenlos regelbare KrafttrainingemaschineContinuously adjustable strength training machine

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

Um ein optimales Training zu ermöglichen, soll die vom Trainierenden zu bewegende Last möglichst genau einstellbar sein, viele Trainingstechniken erfordern eine häufige Neueinstellung der Last. Im Rehabilitationsbereich 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: ööi fortschreitende*- Muskelsrmüdung stetig vermindert, weil so die Belastungsdauer erhöht werden kann.To enable optimal training, the load to be moved by the trainee should be adjustable as precisely as possible; many training techniques require frequent readjustment of the load. In the rehabilitation area, it may even be necessary to change the load during a single movement, e.g. after muscle tears, in order to protect damaged muscle areas. Training is also more effective if the load is steadily reduced as muscle fatigue progresses, because this allows the duration of the load to be increased.

Es sind Kraft tr.»iningsmaschirien bekannt, di-e sürass Anforderungen erfüllen, indem der Trainierende gegen die Kraft eines hydraulischen, pneumatischen oder elektromagnetischen Systems arbeitet. Hisfbei wird im Fall der hydraulischen und pneumatischen Systeme mittels einer Pumpe Druck in Bin®»: Zylinder erzeugt, dessen Kolben vom Trainierenden bewegt wird. B®i den el&kfcrcrvignetisiih&in Systemen wird «»in starkes Dr«^.»oment erzeug* t entweder durch einen über Wirbelstrombremsen gekoppslten Motor orSer ein mat>\>»3tische« Sehfeld.Force training machines are known which meet these requirements by having the trainee work against the force of a hydraulic, pneumatic or electromagnetic system. In the case of hydraulic and pneumatic systems, pressure is generated in a cylinder by means of a pump, the piston of which is moved by the trainee. In the electronic systems, a strong torque is generated either by a motor coupled via eddy current brakes or by a mechanical field of vision.

Bei hydraulischep bzw. pneumatischen Systemen verändert sich die zum Bewegen ü*« Kolbens erforderliche Kraft in Abhängigkeit zur bereits zurückgelegten Wegstrecke. Um «&udigr;&bgr;«..£ Veränderungen zu neutralisieren sind Exzentertriebe erforderlich, die in der Herstellung recht teuer sind. B»i den elektromagnetischen Systemen besteht ein hoher Energiebedarf &ngr; d· nicht ,iur zum Einstellen, sondern auch zum Aufrechterhalten der Last Strom verbraucht wird.In hydraulic or pneumatic systems, the force required to move the piston changes depending on the distance already covered. In order to neutralize these changes, eccentric drives are required, which are quite expensive to manufacture. Electromagnetic systems have a high energy requirement, and electricity is used not only to adjust the load, but also to maintain it.

Da ein Stromausfal* 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 are required to prevent injuries to the person exercising.

Der Erfindung liegt die Aufgabe zugrunde, die Last einer Krafttrainingsmaschine auf eine Meise bereitzustellen und zu regeln, die die Nachteile der bestehenden Systeme ausschaltet.The invention is based on the task of providing and regulating the load of a strength training machine in a way that eliminates the disadvantages of the existing systems.

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

Um ein Schlagen der Antriebekette zu verhindern, welches im unteren Lastbereich dadurch entstehen könnte, daß das Gewicht langsamer zurückläuft als z.B. der vom Trainierenden bewegt· Hebel oder Zuggriff, ist das System mit umlaufenden Kettentrieben versehen, welch· ein aktive« Bewegen des Gewichts in beiden Richtungen ermöglichen.In order to prevent the drive chain from hitting, which could occur in the lower load range if the weight runs back more slowly than, for example, the lever or pull handle moved by the exerciser, the system is equipped with rotating chain drives which enable the weight to be actively moved in both directions.

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

Ein auf Rollen (1) gelagertes, aus rechteckigen Metal1platten bestehendes Gewicht (2) bewegt sich entlang der aus einem Vierkantrohr gefertigten Führungsschiene (5). Der Antrieb erfolgt durch eine umlaufende Kette (4), an der das Gewicht mit einem Bolzen (3) befestigt ist,, Die Kette läuft um das obere Ritzel (6) herum, durch das Vier&mdash; karvtrohr der Führungsschiene hi«dyrc* und um das erste Ritzel des auf einer gemeinsamen Welle (9) verarg-si eher befestigten Ritz el paar es <7). Vom zweiten Ritzel kann nun die Kraft des Gewichtes in Form eines Pr-s*hmoments abgenommen werden. Im gezeichneten Beispiel erfolgt eine übertragung über ijine Endloskette (11) auf ein anderes Ritzel (12>, an dem z.B. ein vom Trainierenden zu drückender Hebel befestigt werden kann.A weight (2) made of rectangular metal plates mounted on rollers (1) moves along the guide rail (5) made of a square tube. The drive is provided by a revolving chain (4) to which the weight is attached with a bolt (3). The chain runs around the upper pinion (6), through the square tube of the guide rail (7) and around the first pinion of the pair of pinions attached to 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, the force is transmitted via an endless chain (11) to another pinion (12), to which, for example, a lever can be attached that the person exercising can press.

Zwei Anschläge (IS)) begrenzen den Bewegungsraum des Gewichts. Die Neigung der Führungsschiene und damit die wirkend» Kraft bzw. Last wird über ein Zugseil (13) verändert, welches von einer Elektrowinde (14) auf&mdash; bzw. abgewickelt wird. Der Drehpunkt der Führungsschiene ist &Lgr; identisch mit dem Drehpunkt des Ritzelpaares (7).Two stops (IS) limit the movement range of the weight. The inclination of the guide rail and thus the effective force or load is changed via a traction cable (13), which is wound up or unwound by an electric winch (14). The pivot point of the guide rail is &Lgr; 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). The arrangement is connected to the frame of the strength training machine using this mounting flange.

Erzielbare Vorteil·!Achievable advantage·!

Die mit der Erfindung erzielten Vorteile liegen zum Einen Im niedrigen
Energieverbrauch, da nur zum Einstellen, nicht aber zum Aufrechterhalten der Last Energie benötigt wird, zum Anderen in der hohen Sicher- ^ helt, da die zuletzt eingestellte Last auch dann erhalten bleibt, wenn | einmal der Strom ausfallt oder eine Störung auftritt. SThe advantages achieved with the invention are, on the one hand, the low
energy consumption, as energy is only needed to set the load, not to maintain it, and secondly in the high level of safety, as the last set load is retained even if the power fails or a fault occurs. S

Ein weiterer Vorteil liegt in der leichten Her^tel1barkeit, da aus- ft schließlich Normteile und -halbzeuge nach DIN verwendet werden. &idigr;A further advantage is the ease of manufacture, since only standard parts and semi-finished products according to DIN are used.
