Definitions
- the invention relates to an ergometer, preferably a bicycle ergometer, with a pedal arrangement mounted in a frame and an adjustable braking device, which optionally engages a flywheel.
- Bicycle ergometers have recently found a wide range of applications. In addition to private use, they are used in medicine, especially in sports medicine for performance diagnostics, as well as to check the progress of training in high-performance sports. Another possible application is in rehabilitation, for example in accident or stroke patients.
- a bicycle ergometer with a pedal arrangement has become known from DE 36 03 853 AI, which has an adjustable braking device and a display instrument for the braking torque.
- a panel is arranged which has a pointer instrument for the torque and the speed. The user of the ergometer thus receives information on the one hand about the torque required to overcome the set braking force and about the speed reached in each case.
- an ergometer is known from DE 42 27 586 AI, which is used to find and train the optimal movement sequence.
- constructive and destructive force components released by a cyclist on the pedals can be recorded in real time and under real training conditions.
- the elastic deformations relevant to the pedal lever as well as deformations of the steering and seat posts are recorded selectively and independently of one another by suitably arranging strain gauges. From the data obtained, the complete movement sequence of the cyclist can be determined and optimized, which means that force components that are converted into forward movement are maximized and force components that cannot be converted into forward movement, for example because they generate a static counterforce, are minimized.
- the device is relatively complex, since up to four possible elastic deformations (bending in the direction of rotation, bending perpendicular to it, elongation in the longitudinal direction of the pedal lever, torsion about the longitudinal axis of the pedal lever) must be recorded and evaluated separately and independently of one another.
- Another class of bicycle ergometers is used in medical diagnostics to determine the aerobic / anaerobic threshold of a patient, whereby the performance is usually increased gradually and different patient data such as heart rate, 0 2 and C0 2 content of the breathing air etc. are determined , Such ergometers are known, for example, from US 4,463,764 A and US 5,782,772 A.
- the known devices are not suitable for recording differences in the pedaling behavior of the left and right leg of a test subject as unaffected as possible by disturbance variables and with high resolution within one crank revolution.
- the object of the invention is, based on an ergometer of the type mentioned at the outset, to show improvements which allow the torque curve of each crank or each leg to be recorded separately with high resolution within one crank revolution.
- the two pedals of the pedal arrangement are mounted independently of one another, with the exclusion of power transmission from one pedal to the other. Furthermore, a separate braking device is provided for each pedal, the braking force of which can be regulated independently of one another. While in conventional ergometers both pedals are attached to a continuous crank axis, the complete mechanical separation of the power flow of the two pedals enables the torque curve to be recorded independently of one another as a function of the crank angle and after processing in a computer unit on a display device in the field of vision of the exercising person or a patient transferred to rehabilitation.
- a torque sensor and / or a speed sensor is located on the crank axis of each pedal, which is connected to a computer unit including a display device, preferably a monitor.
- a computer unit including a display device, preferably a monitor.
- a torque or force / angle curve of the respective leg can be displayed on the monitor.
- the areas of application of the ergometer according to the invention are mainly in two areas: - Sports medicine / performance diagnosis
- an improvement in the biomechanical efficiency of about 25% can be achieved within a short time.
- One-sided stresses that result in signs of wear and tear can be diagnosed and treated early.
- a successful application of the ergometer according to the invention is given in all clinical pictures that result in a force / coordination difference between two extremities, e.g. Stroke, atrophies of various origins, myopathies and much more.
- the two pedals it is also possible to design the two pedals as hand cranks, in order, for example, to restore the interaction of the muscles of the affected arm after a stroke.
- an auxiliary motor with adjustable output it is also possible to connect an auxiliary motor with adjustable output to each of the two pedals of the ergometer.
- each of the two auxiliary motors can have an anti-spasm control, which can be activated automatically when a sudden change in resistance occurs. If a patient uses an ergometer in which pedaling is supported by an auxiliary motor, it is advantageous if the motor switches off or changes the direction of rotation when spasms occur (suddenly occurring, excessively excessive muscle tone). This can prevent the spastic extremity from being violently moved by the auxiliary motor.
- the force separation in the crank mechanism of the ergometer can be produced according to an embodiment variant of the invention in that one of the pedals has a crank axis with a tubular extension and the other pedal has a crank axis with a cylindrical extension, the cylindrical extension being rotatably mounted in the tubular extension.
- the two extensions can have radial bores aligned with one another, the pedal arrangement being fixable in a 180 ° geometry by inserting a fixing screw into the radial bores.
- FIG. 1 shows a schematic illustration of the ergometer according to the invention
- FIG. 2 shows the bottom bracket unit of the ergometer according to FIG. 1 in an axial section
- Fig. 3 is a diagram of the torque curve as a function of the crank angle.
- the ergometer shown schematically in FIG. 1 has a pedal arrangement 2 mounted in a frame 1, which acts via a chain drive 3 on two separately mounted flywheels 4 with a braking device 5, the braking force of which can be regulated independently of one another.
- the braking force can be regulated mechanically or electromechanically by the computer unit 6 in a manner not shown further, for example according to the principle of an eddy current brake.
- the two pedals 7 and 8 of the pedal arrangement 2 are mounted independently of one another - with the exclusion of a power transmission from the pedal 7 to the pedal 8 - in the frame 1.
- the computer unit 6 is connected to a display device 10, preferably a monitor, which is arranged in the visual field of the user.
- the computer unit and the monitor can also be combined into one unit and arranged in the area of the handlebar-like handles of the ergometer.
- a speed sensor 11 can be arranged on each crank axis 7 ', 8'.
- each of the two pedals 7 and 8 of the ergometer can be connected to an auxiliary motor 12 whose output can be controlled, the movement of the extremity affected by the stroke being supported by the auxiliary motor 12.
- FIG. 2 shows a possible embodiment variant of a bottom bracket unit of the ergometer, in which one of the pedals has a crank axis 7 'with a tubular extension 13 and the other pedal has a crank axis 8' with a cylindrical extension 14, the cylindrical extension 14 in the tubular extension 13 is rotatably mounted.
- the crank axis 7 ' is mounted twice in the bearing housing 15 (see bearings 16, 17), the crank axis 8' is also supported twice by the bearing 18 and by the bearing 18 ', which is only indicated by dashed lines, thereby realizing a compact design.
- a spacer sleeve 26 is arranged between the two bearings 16 and 17.
- the two extensions 13, 14 have radial bores 13 ', 14' aligned with one another, the pedal arrangement 2 being fixable in a 180 ° geometry by inserting a fixing screw (not shown) into the radial bores.
- the chainring 19 is fastened on both sides with the aid of an adapter disk 20 to a flange 21 of the crank axis 7 'or 8'.
- the chain fender on both sides is labeled 22.
- the torque sensor 9 consists, for example, of a torsion ring 23 fastened to the crank axles 7 ′ or 8 ′, which is connected to a data transmission preferably fixed to the chain guard plate 22. participant 24 cooperates.
- the signal line leading from the data collector 24 to the computer unit 6 is designated by 25.
- curve R shows the course of the torque as a function of the crank angle, curve L being measured for the left leg and curve R (dashed line) for the right leg, for example.
- the curve R for the right leg was shifted by 180 ° in order to better compare the two maxima.
- the recording on the monitor can be used as feedback.
- an attempt should be made to influence curve R by changing the rotational behavior in such a way that a torque dip in the region of the torque peak is prevented and, for example, a result according to curve V (dotted) is achieved.
