Abstract

Training apparatus gives a measurement of the extent or result of a physical training exercise. Forces, performance, heart frequency, of a person being monitored are given as electric signals and/or being evaluated and being indicated at least partially after comparison and/or combination with pre-set values. The values to be indicated (13, 14, 15) are evaluated as a total and/or time elapsed, are then transformed into a suitable signal and are then reproduced in pictorial form. The values are evaluated in a control section and may then be transmitted to the screen of a TV receiver in the form of a video signal.

Description

"Personal training device"

The invention relates to a personal training device, with the measured values or the like. about the course and / or result of physical exercise, e.g. strength, power, heart rate, of a person monitored in the form of electrical signals and / or evaluated and, if necessary, after comparison and / or combination with predetermined ones Values, at least in part.

Such training devices, also called ergometers, are e.g. from the DE-OS 25 40 493 known. It was essentially about the determination and notification at least one of the parameters that are significant in use, the measured and over a control and implementation device, e.g. in digital form, for Display can be brought. The service performed or performed by the user Strength can be evaluated with it, but also physiological variables such as the Oxygen uptake of the user per kilogram of body weight and minute calculated and displayed.

Since the training effect depends on how far the relevant Person involved in physical exercises, personal data, e.g. age, Gender, weight, heart rate, etc.

specified, e.g. stored in the control device.

During the display, a specific for the person concerned can then be used Conversion can be made so that the training data of different people be comparable in terms of personal stress.

Physical exercise, however, does not come with one-off or short-term To achieve training exercises; As a rule, multiple repetitions are required, preferably a continuous heavy load of e.g. at least 10 minutes, but also up to half an hour and longer. On a sports field or at one Forest run changes the picture of the environment more often, so that a certain intellectual Stimulation is given and fatigue is prevented. There is always one involved in training certain willpower to persevere, which is made easier in this way. However, it should be on one fixed place in the apartment - the equipment for this is available as exercise bikes known - this results from the stationary and narrow environment of a living room or the like. rather the danger of losing or getting tired.

The invention is therefore based on the object of a training device to be trained in such a way that the inertia threshold is reduced and the durability is facilitated in the exercise. In particular, suggestions should be given to the eye that counteract fatigue.

This is achieved if, according to the invention, the values to be displayed evaluated in a control part according to size and / or chronological sequence, in a converted into a suitable signal and represented graphically with an interesting picture content will.

The values to be displayed are preferably evaluated in the control part and into a video signal for display on the screen of a television receiver convicted.

Known devices for monitoring or displaying training values are objectively designed, e.g. for observation by a doctor or a medical Assistants. This is how pointer instruments are often used used, but also oscilloscopes, on which one hand fast oscillations such as heart currents and on the other hand, mean values such as pulse frequency and their limit values are shown. In principle, such devices also enable an objective exercise with an exercise bike Control; however, observing them can easily lead to an additional fatigue effect.

If, according to the invention, the values to be observed are shown graphically the result is a large, possibly colored and therefore impressive display. This ad is combined with interesting picture content that attracts attention of the exerciser excited and so a predominantly mental fatigue through monotony and counteracts boredom.

According to one embodiment of the invention, the representation of the values to be displayed on a television receiver screen. Then as Superimposed image content received via an antenna or from a video recorder used image signal. This image signal can be a game sequence or a Preset training program, which the viewer - the training person - in any follows a certain way and thereby has its own control signal for one that can be influenced Part of the image is generated: the viewer then participates.

The video signals can interact with the control unit or in it contained special circuit groups be designed so that on a varied display next to the immediately displayed measured values and gives an interesting picture, the observation of which is due to the connection with the training exercises attracts attention.

Individual values of the training exercises, e.g. arm or leg movements or lifting weights, displayed as dots or bars will, the location of which may be dependent on the maximum power expended; one recognises then on the television receiver the number and the possibly different result of the individual Exercises. Such results can also last a long time, e.g. several minutes in a row, are displayed so that you can see the course of the training performance. It is also possible to show the achieved values and the number of exercises with digits.

Processes, e.g.

Movement sequences, heart and breathing activity are shown.

The image content may include the essential parts, which are not exclusive serve to display measured values, determined by the signal formed in the control part will. In particular, the image content can give a game-like representation, in which part of the image, e.g.

a roadside, in its location and possibly in its time-dependent change is specified by the control part and at least one other image part, e.g. a Vehicle symbol, is influenced by the person exercising.

Due to the game-like representation, one of the training person influenced image part is assigned a target value or a target value range and is specified are in such a way that on the one hand a certain, For example, a prescribed training program is carried out for reasons of sports medicine, and that, on the other hand, a signal causing an influencing effect, e.g. a warning signal, is triggered when a certain variable exceeds this setpoint or setpoint range accepts or exceeds it.

The image can also be influenced by a measured value, e.g. in the Meaning that the width of a path from the approach of a measured value to a limit, e.g. the heartbeat rate at a maximum value, is influenced in a dependent manner. That Image can also be arbitrary, for example through a targeted movement of the exerciser, e.g. by means of a handlebar or an adjustment knob will. The signal supplied by the control part can also be displayed as a function of time to make the playing conditions more difficult or easier.

If necessary, the physical demands on the training person, e.g. by changing the braking of a bicycle trainer or by changing the The spring tension of a strength trainer can be made more difficult or easier.

According to another development of the invention data and / or signals from several people are also displayed, each of which is work for yourself or in competition. The limit values can be set for each player entered separately.

The default values for a training program that changes over time can be supplied from a tape or disk device. The slow changes can by means of a low frequency transmitter, e.g.

by means of a compact cassette tape, and over a special control part that influence the video frequency signals. The firm or Time-dependent predetermined values of the training program can depend on the personal physiological data of the exercising person adjusted or corrected will.

According to another development of the invention are in the position the trainee's operating elements, e.g. push buttons, through which he affect the display and the image representation, e.g. show other measured values or turn on another TV program as the background.

According to the invention, a game character can be used for training purposes join, possibly as a competition. The necessary training time can be bridged more easily and the desired training effect can be achieved. A possibly tiring concentration to the monitoring of Display instruments are then avoided on the contrary, by observing several display sizes and the further image content overall there is an increased suggestion.

The invention is illustrated below with reference to the drawing, for example explained in more detail that in Fig. 1 the structure of a training device with a bicycle trainer shows in principle, in Fig. 2 the trainee on a frond trainer and in Fig. 3 shows the screen of a television set, which shows a picture when cornering with changing Speed.

In Fig. 1, a bicycle training device is shown schematically at the top left, which carries a handlebar 2 at the top of a main part 1. On the side of the wedge-shaped Part 9, the support 3 for a saddle 4 is attached at an angle. Further Pedal cranks are attached, of which those on a circle indicated by dashed lines 5 revolving crank 6 is indicated on the front side. A exercising one Person 7 then sits on the saddle 4, holding onto the handles of the handlebar 2 firmly and actuates the pedals 6, which are braked to a preferably adjustable degree, E.g. from an electrical generator coupled to it, which is controlled by an adjustable Resistance, e.g. an eddy current brake, is loaded. The speed and, if applicable, the Braking force or

the generated power is converted into an electrical signal, that into a video signal for display on the screen of a television receiver 10 is converted.

Belongs to the training device that causes the mechanical effects a control part 11, to which further, electrically and possibly mechanically separated circuit parts or component groups that are at least partially separated, possibly in separate ones Housings and can be attached in different places.

In Fig. 1 they are shown together for the sake of clarity. An evaluation part 12 in the control part 11 receives measured or control values at input terminals are supplied to terminal 13 values that are generated by the trainee using operating elements, e.g. push buttons 8 on the handlebar 2 can be operated arbitrarily.

The terminal 14 is supplied with electrical values from the training device have been accepted and indicate e.g. power, power, speed, etc. At the clamp Finally, measured values are supplied by the person himself, e.g. heart rate and breathing rate. The connecting cables and terminals shown can be used for the transmission of a plurality of measured values is also multi-core and correspondingly multiple be trained; for the sake of simplicity, they are symbolically shown in FIG. 1 as individual connections shown.

The signals supplied are monitored in the evaluation part 12, if necessary

compared with each other or with specified values, e.g. limit values and / or combined. The signals pretreated in this way then become a combination stage 19 supplied. This receives 18 signals from an image signal stage, which together with the measured values from terminals 13, 14, 15 are to be displayed on the screen.

Stage 18 can be video tape, video disk, or other stages for generating a video signal. The generated video signals can also influenced by a low frequency signal from a tape cassette.

Those combined in stage 19, suitable for the image display Signals are then transmitted via a modulator or transmitter stage 27 and a connecting line 16 a television receiver 20, e.g. at its antenna connection or at its Video recorder connection, supplied.

The video signals can be used on the screen 21 of the television receiver 20 the speed of rotation achieved by the pedals 6 as a point of light 22 in the upper part of the image area which moves sideways depending on the speed. On the left resp. Marks 23 and 24 are attached to the right end of this trajectory, those of the minimum or the maximum speed of the specified training program. The exerciser thus sees immediately how the middle point depends on his stepping wandering here, and it is his job to find this point between the two limit values 23 and 24 to keep. The training program can be carried out, e.g. from a tape values given in the specification part 18 are changed as a function of time; it can also be from an output terminal 17 of stage 18 sends a control signal to the one connected to the pedals Load in the main part 3 are given such that the deceleration is changed. The training program can, for example, switch between fast, easy driving and slow, heavy pedaling, the limit displays 23 and 24 on the screen 21 can be changed to new setpoint values.

On the screen, e.g. as peaks 28, a physiological Measured value, e.g. the pulse rate of the person exercising, can be displayed. In not shown Another information content is also shown on the screen, e.g. a television Radio program broadcast by means of an antenna 25 and is fed to a receiving part 26 in the modulator 27. The received Video signal is then together with the other data of the control part 11 via the Connecting line 16 is fed to the receiver 20.

The user can use the operating elements 8 to view the representations change on the screen. E.g. he can choose another television program or the display of other training data.

Of course, he can use controls in a corresponding manner 8 change the training program yourself, e.g. the load on the cranks.

In Fig. 2, the application of the invention is indicated schematically at a frond trainer, in which on an arched double rail 30 a small Carriage 31 is held with springs or rubber bands 32 and by one on the carriage 31 standing person 33 is moved to one end or the other. Through the The carriage becomes straps 32 when it is relieved by the movements of person 33, withdrawn again; it can thus be shifted alternately to one or the other end position which simulates ski waving.

The forces exerted on the straps 32, if applicable those on the end position buffers The impact exerted on 34 and 35 can be measured in a known manner and converted into a converter 36 can be converted into a suitable signal. The converter 36 belongs to the control part 11, but can be constructed and arranged separately from this. The implementer 36 can in particular contain a counter that records the individual movements, summed up and then on the screen 21 for display.

Fig. 3 shows the contours of a television screen on which by the control according to the invention between two e.g. darker surfaces 41 and 42 a lighter path 45 is formed on which the image 44 of a cyclist moves. The speed of the cyclist 44 relative to the vertically moving roadsides is controlled with a training device according to Fig. 1 of the cranks 6, while the lateral position can be influenced by the handlebar 2. Through the surfaces 41 and 42 the picture content is given, which is due to its connection with the Exercise occupies and be the attention of the trainee Interest is so demanding that there is no danger of boredom. The lateral movements (curves) of the path 45 are according to one of the default level 18 given sequence controlled; the width of the path and the speed of the vertical shift can also be specified, possibly adjusted later will. Due to the width of the path and the speed, the required Training performance and also the attention and speed of reaction of the Exercising be determined and practiced. When the right position of the cyclist 44 is not adhered to, error points can be issued and displayed at 46 if necessary will. The distance covered can appear at the top left.

It is also possible to use two fields of a path 45 of the same type next to each other on the screen, so that then two trainees one Be able to run a competition.

The control of the cyclist symbol 44 is expediently carried out in such a way that the shift when approaching the upper or lower edge of the image not further changes are made in such a way that the cyclist does not disappear from the field of view.

By controlling the speed of the path 45 and possibly a A corresponding change in the braking of the pedal drive 6 can be achieved, that the training state is changed similar to a bike ride in mountainous areas Terrain.

The image can also be influenced by a measured value; e.g. can the path 45 can be controlled more closely if the pulse of the exerciser becomes too fast. The lateral movements of the cyclist symbol 44 can be carried out with the help of the handlebar 2 are executed. A delay element can also be used in control stage 12 be installed in such a way that the side shift only takes place after a certain time what comes closer to the natural driving style becomes effective. If the trainee does does not comply with the given driving line due to the changes in path 45, he touches the edges of the road, which can trigger points of error, e.g. in the upper right corner of the screen, represented by the number 46, can be displayed. If there is a threat of overload the width of the path is controlled much narrower, driving becomes difficult and the frequency of mistakes increases: This indirectly prompts the trainee to staying away from an overload.

A time-dependent signal can also be generated in the control part 11, through the part of the image influenced by the training person, a target value or a setpoint range is specified. When approaching or exceeding the setpoint can then e.g.

acoustic warning signal can be triggered. Can also act as a warning sign the The color of the picture can be changed.

Data and / or signals from several people can also be shown on the screen which each operate for themselves or in competition. E.g. can the representation shown in Fig. 3 2 times side by side on the screen appear so that each of the competitors his own position and that of the other player can overlook. In addition to the game data, other data, e.g. physiological data, as indicated on the screen 21 in FIG. The data can be used as points in different positions and / or as bars of different lengths next to each other are displayed; they can also only be used temporarily, e.g. alternately one after the other and if necessary, periodically repeated, which is a further incentive for the exact Observation causes.

When a warning signal occurs, the training device can turn into a Be transferred to the state of significantly lower stress.

Particularly in the case of a training device that is not operated in a stationary manner e.g. in the case of an expander, it may be useful to have at least one signal from to wirelessly transmit the training person or the training device to the control part 11, e.g. high frequency or by ultrasound.

The evaluation part 12, the image signal stage 18, the combination stage 19 and the modulator or transformer stage 27 are preferably structurally connected and if necessary form an additional device that can be retrofitted to an existing main trainer part 1 or the like. can be connected.
