Definitions

  • the invention relates to a device for moving the legs with a crank mounted on a frame, with pedals mounted thereon, with a device for firmly connecting the feet to the pedals and with an electric motor for driving the crank, precautions being taken to prevent the Stopping the crank at a continuously adjustable section modulus.
  • a device of this kind is known from GB-A-976 558. It is used for the passive movement of the extremities of weak or paralyzed, z. B. paraplegic patients.
  • the device is designed so that it can also be used by wheelchair users sitting in a wheelchair. The movement exercises are of great help for such patients, since this stimulates the blood circulation as well as the bowel and bladder functions.
  • a torque-limiting clutch in the form of a friction wheel drive is attached between the electric motor and the crank, the force with which the friction wheel presses against a pneumatic tire wheel being adjustable by means of a wing screw. This gives very weak, but not completely paralyzed, patients the opportunity to use their remaining muscle strength to counteract the motor drive, ie to train, and to stop the crank while the motor continues to run.
  • spasms difficulties arise in the known motor-driven movement device due to the occurrence of muscle cramps, so-called spasms.
  • the problem occurs particularly when wheelchair users use such devices independently because qualified assistants who are familiar with the occurrence of spasms are not present.
  • the fear of injuries or just the insecurity that the motor drive cannot be controlled in the event of cramping causes many sufferers not to make use of the training offer which is desirable in itself.
  • the mechanical friction torque setting is insufficient in terms of accuracy and reproducibility.
  • the invention has for its object to design a device of the type described in the introduction so that when muscle cramps occur in the moving extremities, injuries are excluded and these muscle cramps can be resolved quickly and effectively.
  • an electronic control device for the engine which has the functional features specified in the claim.
  • the general electronic technology in the field of drive controls is used, as has also become known in neighboring medical applications.
  • the combined functional features could have such an advantageous therapeutic effect.
  • the setting of the maximum torque can be made independently of the speed of rotation for each individual patient depending on the given medical situation.
  • the correspondingly precise and sensitive adjustability of the reversal point is also important in view of the fact that, in the case of cranks with an adjustable diameter, the section modulus does not only depend on the leg mobility of the patient concerned, but also on the crank diameter set.
  • the device according to Figures 1 and 2 comprises an H-shaped frame seen from the side with an upstanding, length-adjustable handlebar 1 and two transverse legs 2 with rubber feet 3.
  • Halfway up this frame carries an elongated housing 4, on which one Crank 5 is rotatably mounted about a horizontal axis 6.
  • the crank 5 is driven by an electric motor contained in the housing 4.
  • a total of 7 pedals are mounted.
  • the bearing axles of the pedals are labeled 8.
  • the pedals 7 each consist of a footplate 9, a shield 10 shielding the foot from the crank 5 and a curved heel support 11, which parts are firmly connected to one another.
  • a cross shaft 14 is rotatably supported, the end portions of which are designed as handles 15.
  • two rubber ropes 16 are fastened with one end each and are wound up a little.
  • the other two ends of the rubber cables are attached to the upper ends of the connecting rods 12 and to the calf shells 13.
  • the cross shaft 14 can be locked by means of a clamping screw 17.
  • the handle bar 1 carries a small table top on which an electrical control unit 18 for the drive motor contained in the housing 4 is built.
  • the operating elements of this control device 18 indicated in the drawing are arranged on the user side and are therefore also located in the grip area, where they are easily accessible.
  • a clamping device for fixing the user's feet on the footplate 9 is also arranged on the pedals. It has an actuating lever 19 bent toward the user and a pressure piece 20 which rests resiliently on the back of the foot when the lever is in the appropriate position. For boarding, the pressure piece 20 can be swiveled out laterally.
  • the movement device described can be used by a paraplegic wheelchair user, for example, as follows: He approaches the device from the front and places his feet on the foot plates 9 of the pedals 7, which are presented ready for entry. The lower legs are in the calf shells 13 the feet the necessary fixation on the pedals. The tensile forces of the rubber ropes 16 can be suitably adjusted after loosening the clamping screw 17 by turning the handles 15 and further winding.
  • the control unit 18 continuously monitors the torque output by the drive motor electronically. If a muscle spasm occurs and the drive torque reaches its preset limit value due to the braking, the motor is stopped, for example. In this case, too, a restart of the motor can be programmed in the opposite direction.
  • spasms can be alleviated or completely eliminated by changing the direction of rotation several times at low torques. In any case, the disabled can choose the most comfortable form of movement in many variants.
