Definitions
- the invention relates to a treadmill ergometer with the features of the preamble of claim 1.
- Such treadmill ergometers are known from the prior art and are used for analysis and / or therapy of the movement sequence of a subject when walking or running or for describing the kinetic concerns of movement via the Driving power in relation to metabolic organ reactions.
- the deficit in the exact separation of kinetic from kinematic issues could not be fully eliminated because a certain transition zone of the subject in the Center of the treadmill must be taken into account. If the middle of the treadmill is exceeded, influences e.g. B.
- test person makes sure that he does not cross the middle of the treadmill, an exact analysis is just as impossible, since a run or gait that is influenced by the test person in such a way no longer corresponds to the actual movement sequence, so that meaningful, analytical requirements no longer meet is spoken.
- the invention is therefore based on the object of providing a treadmill ergometer which, even when the middle region of the treadmill is crossed, enables an exact analysis or therapy of the movement sequence or subjects. This object is achieved by a treadmill ergometer with the features of claim 1.
- the treadmill ergometer there is at least one secondary treadmill between the driven main treadmills, preferably two secondary treadmills, which are not driven by themselves.
- the drive of the secondary treadmill or treadmills takes place in that they are taken along by the subject's shoe when the respective main run is exceeded. An interaction between one foot of the test person and the driven main treadmill assigned to the other foot can thereby be avoided, apart from extreme cases, which enables a very exact analysis or therapy is made possible.
- FIG. 6 shows a view corresponding to FIG. 5 of another embodiment
- Fig. 7 is a schematic longitudinal section through the treadmill ergometer with a subject
- Fig. 8 is a detailed view of the treadmill ergometer in the area of the drive
- FIG. 9 schematically shows a circuit diagram of the drive and control system of the treadmill ergometer according to the invention.
- the treadmill ergometer has a frame 1 which can be adjusted relative to its horizontal orientation by means of pressure medium cylinders 36 or other suitable adjusting devices, in order to be able to simulate different terrain conditions.
- Two main treadmills 2, 3, which are driven by motors 23a, 23b, and auxiliary treadmills 4, 5, which are not driven about axes 17, 19, are rotatably mounted on the frame 1 about axes 17, 18.
- FIG. 5 it can be seen that the left main treadmill 2 and the left auxiliary treadmill 4 on the one hand and the right main treadmill 3 and the right auxiliary treadmill 5 on the other hand overlap.
- the secondary treadmill 4 is entrained on the one hand by the frictional force exerted by pressing the main treadmill 2 onto the secondary treadmill 4 and on the other hand by the frictional forces which exist between the main treadmill 2 and the treadmill 4 and the subject's shoe 7 occur.
- the entrainment of the secondary treadmill 4, 5 by the main treadmill 2, 3 can be improved by slight profiling in the overlap area, contact being made only in the event of occurrence. may. If the test subject crosses the central region even further, as is shown schematically in FIG. 6, the opposite treadmill 5 is also carried along by the shoe 7. However, since only one driven main treadmill 2 is still loaded, but the second main treadmill 3 is not, there is no falsification of the measurement results or the movement sequence as would be the case in the prior art.
- FIG. 5 shows an embodiment in which the main and secondary conveyor belts 2, 3, 4, 5 are supported by rollers 11, 11a, which are mounted on bearing blocks 9.
- the main and secondary raceways 2, 3, 4, 5 are supported on sliding blocks 10, 10a via sliding surfaces 12, 12a.
- the rollers 6 in the middle area are raised above the tread of the auxiliary treadmills 4, 5, 5 and 6 show. This means that even if the middle area is slightly crossed up to the area of the secondary track 4 or 5, which is assigned to the other leg, no contact is made with this other secondary track 4 or 5, so that even when walking, the middle area is crossed is enabled to a certain extent without falsifying the analysis or therapy.
- roller field 6 in the central region can also be replaced by a further, non-driven treadmill or can be omitted entirely.
- the bearing body 9 or slide blocks 10, 10a are supported on a weighing platform 8, which is arranged between the strands of the main and secondary conveyor belts 2, 3, 4 and 5.
- This weighing platform 8 is supported on the frame 1 via load cells ZI, Z2, Z3.
- the main treadmills 2, 3 are driven by means of electric or hydraulic motors 23a, 23b, which are adjustably mounted on the frame 1 via flanges 22a, 22b.
- the drive motors 23a, 23b are connected via couplings 24 to the drive shafts 18a, 18b or deflection rollers 14 of the main treadmills 2, 3.
- the main treadmills 2, 3 run around deflection rollers 13 on a shaft 17.
- the secondary conveyor belts 4, 5 likewise run on the one hand around deflection rollers 15 on the shaft 17 and around deflection rollers 16, the shafts 19a, 19b of which are offset inwards (distance al - a2 in FIG. 7) from the drive shafts 18a, 18b of the main conveyor belts 2, 3 are. Due to the separate storage of the main treadmills 2, 3 and secondary treadmills 4, 5 on their own shafts 18a, 18b, 19a, 19b, a separate adjustment of the tension of the respective treadmills is independent of one another by means of tensioning elements 21, e.g. Set screw, possible.
- the clutches 24 allow compensation for possible, slight displacements of the drive shafts 18a, 18b with respect to the drives of the drive motors 23a, 23b.
- the diameter D1 of the deflection rollers 13, 14 of the main conveyor belts 2, 3 is slightly more than twice the thickness of the secondary conveyor belts 2, 3 than the diameter of the deflection rollers 15, 16 the secondary conveyor belts 4, 5 (Fig. 7).
- the main treadmills 2, 3 are also assigned measuring devices which record the actual speed of the main treadmills 2, 3.
- the speeds detected in this way and the forces detected by the load cells ZI, Z2 and Z3 assigned to the weighing platform 8 (FIG. 9) enable a very exact analysis of the conditions when running or walking.
- the control or measured value acquisition takes place as in
- the circuit diagram of FIG. 9 is shown schematically, as follows:
- the test subject is connected via a tension element 25 (FIG. 7) to an actuator 26 which detects the distance between the subject and the actuator 26.
- This measured value is fed to a window comparator 27 which compares whether the measured value lies between an upper limit value L-, ax and a lower limit value L min . If the measured value is above I -, -, ie if the subject begins to run faster, the speed of the drive motors 23a, 23b is increased until the measured value is again within the two limit values. If L falls below m , the speed of the incoming drive motors 23a, 23b reduced accordingly.
- the process computer is equipped with a RAM capacity which is sufficient only for the analog / digital conversions of the measured values 29, 30, ZI, Z2, Z3 and the interface control 35, so that there are no undesirable or dangerous repercussions or influences on the control of the drive speed of the main treadmills 2, 3.
- the test person first steps only on the non-driven auxiliary treadmill on the opposite side and not on the main treadmill there, so that the disadvantages mentioned at the outset are avoided.
- the treadmills are carried along on the one hand by the friction between the sole of the shoe and the treadmills 2, 3, 4, 5 contacted by them, and on the other hand by a frictional connection between the main treadmills 2, 3 and the secondary treadmills 4, 5 in an overlap area.
