Abstract
An exercising apparatus for exercising at least one limb, having a supporting frame and at least one crank which is arranged on a rotation shaft assigned to the supporting frame, and having at least one limb support which can be fastened to the at least one crank at different radial distances from the rotation shaft. A detector is provided for detecting the radial distance of the at least one limb support from the rotation shaft. The invention further relates to a limb support and to a method for determining the force acting on a limb support of an exercising apparatus.
Claims7
An exercising apparatus for exercising at least one limb, the exercising apparatus comprising:
- a supporting frame;
- at least one crank arranged on a rotation shaft assigned to the supporting frame;
- at least one limb support adapted to be fastened to the at least one crank, wherein the at least one limb support is configured to be fastened at varying radial distances from the rotation shaft;
- a detector to detect the radial distance of the at least one limb support from the rotation shaft, the detector comprising a Hall sensor positioned on a circuit board disposed stationary to the rotation shaft;
- and
- a plurality of receptacles and/or an elongated hole, in which the limb support with a pin having a magnet is adapted to be inserted, is formed in the crank, wherein the crank moves past the circuit board.
A method for determining a force acting on a limb support of an exercising apparatus, the method comprising:
- positioning the limb support on a crank at a radial distance from a rotation shaft of the crank;
- detecting the radial distance via a Hall sensor positioned on a circuit board disposed stationary to the rotation shaft;
- and
- evaluating a measured value detected by the sensor in conjunction with a torque acting on the rotation shaft,
- wherein a plurality of receptacles and/or an elongated hole, in which the limb support with a pin having a magnet is adapted to be inserted, is formed in the crank, and
- wherein the crank moves past the circuit board.
An exercising apparatus for exercising at least one limb, the exercising apparatus comprising:
- a supporting frame;
- a crank arranged on a rotation shaft assigned to the supporting frame;
- a limb support adapted to be fastened to the crank at varying radial distances from the rotation shaft;
- a detector to detect the radial distance of the limb support from the rotation shaft;
- and
- a pin having a bar magnet with a north-south pole alignment coaxial with an axis of the pin.
