Definitions

  • the invention relates to a training device for developing and strengthening the muscles and joints of an exercise person through back and forth movements under load.
  • Such devices known in practice as body building devices or power machines, are known in which the load is formed by weights.
  • These weights which are usually guided on rods, consist of individual elements of equal weight, which can be combined in any number to form a block, depending on the desired load. In the rest position, such a block is located at the lower end of a vertical guideway.
  • the weights are more or less frequently pulled up and down again from their rest position by means of a handle and ropes which are fastened to the weight block and deflected by rollers at the upper end of the guideway.
  • Training devices are also known in which springs, mostly tension springs, are used instead of weights.
  • springs mostly tension springs
  • the disadvantages of such devices are essentially the same as for the devices described above that work with weight elements. Adapting to individual load requirements is often even more difficult and only possible with considerable effort - apart from the difficulties of changing the springs, these cannot be combined to the same extent as weights. In order to be able to correspond to each load case, a large number of springs must therefore be kept available, which, in addition to requiring considerable space, also entails a high capital expenditure.
  • training devices are known in which the movement of the exercising person is opposed by a braking torque by one or more hydraulic or pneumatic power cylinders.
  • This type of power machine allows the muscles to be subjected to changing loads; however, such devices are characterized by a high level of technical complexity and high maintenance requirements, so that they are often out of the question for training studios for commercial reasons -

  • the electric motor generating the load is reversible, that is, it can be changed in its direction of rotation.
  • Such a reversal of the direction of rotation is not necessary for a simple exercise, for example a pulling or lifting exercise, if the exercise is carried out correctly, because after each loading stroke in which the motor is braked beyond standstill and moved in the opposite direction of rotation, the motor by itself through de Relief runs in its actual drive direction and returns the handle to the starting position.

Abstract

Un exerciseur pour développer et fortifier les muscles et les articulations par des mouvements de va-et-vient sous charge produit cette dernière grâce à un moteur électrique (20) réversible et pouvant être freiné en passant par l'arrêt. La tension aux bornes dudit moteur est régulable vers le haut en continu et son couple de sortie peut être converti, par l'intermédiaire d'un réducteur (28, 30), en une force linéaire faisant travailler les muscles de la personne qui s'entraîne. A cet effet, le moteur (20) est un moteur à courant continu à caractéristique shunt, qui possède un stator à pôles à aimants permanents. L'exerciseur selon l'invention permet, de manière simple, une adaptation individuelle de la charge à la personne qui s'entraîne et à l'exercice à exécuter, éventuellement avec une préprogrammation.
