Definitions

  • the invention relates to a device for carrying out performance training, performance physiological tests or medical, in particular sports medicine or cardiological rehabilitation measures; the new device is correspondingly versatile and expandable.
  • Performance training with the help of a device can be carried out at home or in the quarters of a sports club, makes the athlete independent of the weather and has a time-saving effect; Above all, it can be precisely dosed according to intensity and duration, provided the device has suitable facilities for this and conveys measured values.
  • a device is also called an exercise bike, and it has long been known that such a device can also be of value for general cardiovascular training for those not directly interested in sports, for which the term fitness training has been introduced.
  • Performance physiological tests are concerned with sports medical or cardiological diagnostics, rehabilitation measures are primarily concerned with the treatment of accident injuries or cardiac patients; for these purposes it is essential that the device provide a series of reliable measurement data.
  • many heart diseases such as diseases of the coronary arteries
  • a so-called stress is usually required for an adequate functional assessment, as is the case in the relevant specialist literature deviating from the terms of technical mechanics, is called uniform.
  • a so-called muscular workload is the best clinically established and tried and tested method.
  • the degree of exposure must be measurable and so strong that it allows functional healthy people to be distinguished from sick people and the functional range of performance of the examined or patient to be measured.
  • stress is in principle subject to the same principles of modern training theory as apply to the training of healthy people, and that a desired training effect requires a dose of stress of sufficient intensity, duration and frequency, only in the case of therapy the dosage is based on an exact one to choose more carefully, comprehensive diagnosis and reliable measured values and monitoring measures; but here, too, repeated measurement of the functional range provides the necessary information about any improvement in the patient's condition or about a possibly necessary change in the dosage of the stress therapy.
  • So-called bicycle ergometers have mainly been used for the above purposes, in which the user takes a seat on a kind of saddle and a handlebars dummy to be able to hold on, as well as pedals similar to those available on bicycles. It is a complex, heavy, space-consuming device, so that it can hardly be considered as an exercise bike, and it is perceived as a particular disadvantage that the sitting position and posture are significantly different than with a personal, familiar bicycle. This cannot be remedied in principle either, because the bicycles are so differently designed in this regard that it is impossible to generally imitate this in a bicycle ergometer.
  • the so-called pedal comfort does not correspond to that of a bicycle, which is irritating and cumbersome when used, and in some embodiments, the evaluation of the data supplied is so critical or tedious that it requires a special operator and not for the sweating and panting user can still be expected, e.g. running mental arithmetic to multiply torques and speeds plus minus this or that correction.
  • Roller systems have also become known, in the holding device of which the user installs his own bicycle. These are bulky frames, which also fix the handlebar and the pivotable parts of the bicycle, and these roller systems do not allow metering or measuring the load on the user, so that they are more of a toy than a training device and for diagnostic purposes or completely unsuitable for therapeutic purposes. Since the drive (bicycle) is separate, beyond the influence of the manufacturer and a variable that cannot be influenced by him, there are further problems due to tires, rollers etc. - This is illustrated below - and it has been believed for many years that it is impossible to solve all of these problems until a roller system is suitable for the purposes mentioned.
  • the user uses his usual bike, so that the sitting position and posture are favorable for him and he can adjust his pedal frequency to the prevailing circumstances with a possible gear shift - just as usual, so that he adds physical and not unusual mental stress and he the body posture in which he is already more or less pre-trained, which in particular excludes a relative overuse of muscles not otherwise trained.
  • the new device can be made so small that it only extends below and close to the area of the rear wheel, hardly noticeable there and, in addition, only protrudes to the wheel hub on one side.
  • This will include possible by mounting the bicycle, e.g. with an approximately quarter-circle bent tube, which can be pivoted, pulled out and locked in a sleeve attached to the bottom of the device and with its upper e.g. attacks the fork-shaped end on the saddle carrier, remains limited to this and does not also somehow guide, fix and clamp the part of the bicycle that can be pivoted with the handlebars and clamps it in a frame. It has been shown that this - contrary to previous opinion - is quite sufficient, even better and more pleasant for the user compared to rigid fixing of the handlebars and the front wheel, so that the advantage of a small footprint was not bought with a disadvantage.
  • the flywheel has the important function of providing pedaling comfort; it must be difficult for this or be brought up to high speed by a transmission gear.
  • a powerful permanent magnet is suitable as a magnet for the eddy current brake, it makes it independent of the mains.
  • the eddy current brake has the unique advantages for the present purpose, wear-free ⁇ unchangeable and silent to work and in the simplest way to be adjustable within wide limits over its air gap width as well as to deliver the minimum measurement value required for every serious application, which is based on the load of the Lets users close and their dosage allows.
  • This measured value can be the braking torque exerted by the eddy current brake, which can be determined in such a way that the magnet is rotatably mounted and is connected to a pendulum; This in turn can move a pointer over a scale - or a scale over a pointer - whereby it is advisable to calibrate the scale in a power quantity such as watts and to arrange it at least three times, for example with the three parameters 20, 30 and 40 km /Hours. Now one does not say out of the blue that this is wrong: a moment is measured, and even if the load on the user is an achievement, it is not simply a function of just the moment, but the product of this and the very different choosing speed.
  • the correction to take account of the frictional losses can be made, for example, by adjusting the air gap of the eddy current brake or the effective length of the pendulum or the angular position of its center of gravity - an additional weight on the pendulum can also be made adjustable, or in the display device, for example, by adjusting an associated pointer relative to the associated scale. In the latter case, however, the non-linearity of the scale must be taken into account and at the design of the adjustment must be taken into account, while when adjusting the pendulum or an additional weight on the pendulum the sine function of its deflection angle is automatically included in the correction value. If the display is made electrically, there are further obvious and known possibilities for this correction, even at the simplest level, for example with the aid of a corresponding non-linear potentiometer.
  • the weight of the user can be made adjustable by hand, but it can also be detected automatically by a scale provided in the device, e.g. with a pressure-dependent semiconductor under at least one of the roller bearings and inclusion of the associated circuit in an electrical display device of the aforementioned type, which then works "foolproof"; weight adjustment cannot be forgotten.
  • a correction table or a diagram to be used for this would be a rather uncomfortable remedy.
  • Friction losses which are heavily dependent on the weight of the user, does not exist in the case of bicycle ergometers because they do not bear this weight on rotating parts.
  • the following numerical example illustrates the extent of this dependency in the case of roller scaffolds and thus the importance of correcting the friction loss, taking into account the user weight: For an example and a speed corresponding to a driving speed of 20 km / h. Friction losses increased by 30 watts when a user weighing 60 kg sat on the bike, and by 45 watts when a 90 kg user did it - which should perhaps be able to do 150 or 250 watts, which shows how big the importance of this correction is.
  • the new device is provided with a tachometer, this can have a display calibrated in terms of speeds and / or corresponding driving speeds; however, it can also be set up in such a way that the use of its measured values takes place elsewhere, e.g. in a mechanical or electrical device known per se, which forms the product of the respective measured values of the braking torque and the speed.
  • a correction of at least one of these measurement values instead of or additionally of the product, can be provided such that the product is at least approximately equal to the service provided by the user.
  • a display device for the respectively set air gap width can be provided, which can then be preset to an at least approximate value based on experience or a diagram or a table.
  • the air gap width can also be used in a possibly provided electronic device for the input and output of data. Further ease of use can be achieved by letting a control lamp light up for certain or preselectable values of this or that parameter, which saves the user from reading on a scale or a numerical display. This is not an exaggeration, although one only has to think of glasses wearers who are certainly happy and ashamed if they do not have to wear glasses during this sweaty activity, just by scales or numbers to be able to read.
  • the new device can also, combined with a pulse rate monitor as an accessory, have a device which determines and displays its maximum oxygen absorption capacity from the power determined and the pulse rate of the user which occurs in the stationary state, taking into account his gender, age and body weight.
  • a pulse rate monitor as an accessory, have a device which determines and displays its maximum oxygen absorption capacity from the power determined and the pulse rate of the user which occurs in the stationary state, taking into account his gender, age and body weight.
  • Known microprocessors easily do this; The gender and age of the user can only be entered, and if his weight is not measured by the device, it must also be entered.
  • an operating hours counter and a device can also be provided, which determines and displays the calorie consumption and the work performed by the user in training units or joules from the data available in this way.
  • Such devices are known per se and therefore do not require a detailed description here.
  • the new device is located below and on one side next to the rear wheel of the bicycle, the user must occasionally turn to read it when the display device or a plurality thereof is mounted directly on it; instead, in order to save him this or the hardly less inconvenience of reading through a rearview mirror, he can look at the user Arrange the field and provide mechanical or electrical means known per se for the transmission of the measurement or display values (flexible shaft, cable, etc.).
  • a roller 7 located behind the cutting plane is mounted on a shaft 8 in a bearing 9 on a support 10; at the right end, not shown, the roller 7 is mounted similarly.
  • another roll is to be thought of as roll 7; the rear wheel of the bicycle is on the rollers.
  • a gearwheel 11 is fastened on the shaft 8, and a gearwheel that is the same as the gearwheel 11 can be thought of on the shaft of the second roller lying in front of the cutting plane.
  • a toothed belt 12 runs over these two toothed wheels and via a toothed wheel 13 on the shaft of the eddy current brake.
  • the gear 13 is rotatably mounted on a bearing bush 14 and, for example, by means of indicated screws with a brake disc 20.
  • a brake disc 20 made of aluminum, in which a permanent magnet 24 induces eddy currents when the brake disc rotates.
  • a flywheel ring 21 made of a heavy metal is attached to the brake disc 20.
  • the permanent magnet 24 is rotatably mounted on a bearing bush 26, and a weight 23 is attached to it via a web 22, whereby a pendulum is formed.
  • the bearing bush 14 has at its left end a flange which prevents axial displacement of the brake disc 20; at its end shown on the right, the bearing bush 14 is screwed through a cross member 17 'of the frame and secured in front of it by a lock nut 19 together with a washer.
  • the minimum gear required 13 and the associated brake disc 20 and an insert 15 in the axial direction is adjusted by screwing the bearing bush 14 more or less into the cross member 17 '. Then screw a threaded bolt 16 in the drawing from the left into a cross member 17 connected to the frame and through a V-belt pulley 25 into the bearing bush 14 and secure it on the outside with a lock nut 18th
  • the bearing bush 26 is screwed into the V-belt pulley 25 up to the stop and, with a flange at its other end, ensures only minimal axial play of the permanent magnet 24.
  • the permanent magnet 24 is approached or removed from the brake disk 20 , ie a desired air gap width a of the eddy current brake can hereby be set.
  • a V-belt not shown, connects the V-belt pulley 25 to a device, not shown, for adjusting the air gap width a. It can be seen that this is not changed in the event of a pendulum deflection of the parts 22 and 23 and thus a rotation of only the permanent magnet 24, not also the V-belt pulley 25.
  • a simple display device for the braking torque of the eddy current brake is also not shown; it can e.g. consist of a scale on the outer circumference of the permanent magnet 24 and a pointer attached to the frame.
