Definitions

  • the invention relates to a training device according to the preamble of claim 1.
  • a lever provided with two handles is pivotably mounted on a vertical support about a horizontal axis.
  • the piston rod of the hydraulic piston-cylinder unit is articulated to the lever between the handles and the articulation point on the support, the cylinder of which is articulated below the articulated connection of the lever to the support.
  • the lever provided with handles can only be pressed down or raised for exercise purposes, so that it has only a limited area of application.
  • the possible uses of the known training device can not be expanded easily because the lever with the hydraulic cylinder and the support is a space-consuming construction that can be difficult to adapt to other movements to achieve other training effects.
  • a training device in which a lever is connected to a pivot shaft, the rotational movement of which is transmitted by a chain drive to a second pivot shaft, to which a lever is connected, to which one end of a gas spring is articulated , whose other end is pivotally mounted in the frame.
  • This well-known training device is provided with a very complex and space-consuming gear for converting a rotary movement into a translatory movement, so that the adaptation of this device to different exercises requires an additional considerable design effort.
  • a training device in which the lever is rigidly connected to the pivot axis and is arranged approximately perpendicular to the pivot axis.
  • a leg receiver shell which is connected to the lever, can be strapped onto the lower leg of the person practicing.
  • the knee joint can then be arranged in the extension of the pivot axis, so that the pivot axis and the axis of rotation of the knee joint are aligned with one another. If the practicing person now bends or stretches the lower leg, the lever rotates accordingly about the pivot axis.
  • the object of the invention is therefore to provide a training device of the type specified at the outset with which the stresses on the cartilage and ligament apparatus of the exercising person can be reduced.
  • this object is achieved in that the lever can be deflected in a direction perpendicular to its direction of movement.
  • the training device according to the invention is able to follow the natural movement sequences of the human body or the joints of the human body without generating feelings of insecurity in the exercising person.
  • the training device according to the invention can absorb one-sided loads in the joints of the exercising person, distribute them evenly and thereby protect the cartilage and ligament apparatus, thus preventing irritation or inflammation symptoms on the joint.
  • the object underlying the invention is further achieved by the features specified in the characterizing part of the independent claim 2.
  • the lever is pivotally mounted on the pivot axis about an axis of rotation running perpendicular to the pivot axis and perpendicular to the lever.
  • the deflectability of the lever in a direction perpendicular to its direction of movement is thus achieved in that the lever is pivotally mounted on the pivot axis about an axis of rotation running perpendicular to the pivot axis and perpendicular to the lever.
  • This arrangement of the lever is able to move on a rotatable plane because there are two axes of rotation that are perpendicular to each other.
  • the pivot axis is pivotally mounted about an axis of rotation running perpendicular to the pivot axis and essentially parallel to the lever.
  • the possibility of compensating for the respective joint of the practicing person is thus achieved in that the pivot axis is pivotally mounted.
  • the axis of rotation on which the pivot axis is mounted can run parallel to the lever when the lever is in the rest position. If the lever is deflected in the course of the exercise, the lever on the one hand and the axis of rotation on which the pivot axis is mounted, on the other hand, are at an angle to one another which corresponds to the deflection angle of the lever.
  • the third solution of the object on which the invention is based is particularly suitable for movements of the human ankle.
  • the lever with the pivot axis is non-rotatable and in Direction of the pivot axis connected longitudinally.
  • the deflectability of the lever in a direction perpendicular to its direction of movement is thus achieved in that the lever is longitudinally displaceably connected to the pivot axis in the direction of the pivot axis.
  • the lever must also be non-rotatably connected to the pivot axis so that torque can be transmitted from the pivot axis to the lever.
  • the object on which the invention is based is further achieved in that a cross piece running parallel to the pivot axis is connected to the lever, along which a leg pickup is guided so as to be longitudinally displaceable.
  • the deflectability of the lever in a direction perpendicular to its direction of movement is achieved in that the leg receiver shell is guided in a longitudinally displaceable manner on the crosspiece.
  • the pivot axis is pivotably mounted about an axis of rotation running perpendicular to the pivot axis and essentially parallel to the lever, the axis of rotation can also be arranged at a distance from the pivot axis.
