Abstract

Das digitale Anzeigeinstrument für ein Körpertrainingsgerät, insbesondere ein Rudergerät, umfaßt einen ortsfest an einem Grundrahmen des Trainingsgeräts angebrachten Sensor (19) und ein an einem Handhabungsteil, insbesondere dem Rollsitz des Rudergeräts, angebrachtes Sensorauslöseelement (21). Eine Auswerteschaltung spricht auf die beim Vorbeibewegen des Auslöseelements (21) von dem Sensor (19) erzeugten Steuerimpulse an und ermittelt neben der Trainingszeit leistungsbezoge Daten, wie z.B. die Gesamt-Ruderschlagzahl und die momentane Ruderschlagrate, die auf einem Anzeigedisplay (41, 55, 65) angezeigt werden. Für eine selbsttätige Ermittlung der Trainingszeit wird eine Trainingszeit-Meßeinrichtung (35) durch Steuerimpulse des Sensors (19) gestartet. Eine Stop-Einrichtung (45) stoppt die Trainingszeit-Meßeinrichtung (35), wenn innerhalb eines vorbestimmten Zeitintervalls kein Steuerimpuls von dem Sensor (19) erzeugt wird. Eine Unterdrückungseinrichtung (49) unterdrückt bei Trainingsbeginn zumindest den ersten Steuerimpuls, um unbeabsichtigtes Starten der Trainingszeit-Meßeinrichtung durch anfängliches Verstellen des Handhabungsteils zu verhindern.The digital display instrument for a body training device, in particular a rowing machine, comprises a sensor (19) fixed to a base frame of the training device and a sensor release element (21) attached to a handling part, in particular the rolling seat of the rowing machine. An evaluation circuit responds to the control pulses generated by the sensor (19) when the trigger element (21) moves past and, in addition to the training time, determines performance-related data, such as the total rudder stroke number and the current rudder stroke rate, which are shown on a display (41, 55, 65). A training time measuring device (35) is started by control pulses from the sensor (19) for an automatic determination of the training time. A stop device (45) stops the training time measuring device (35) if no control pulse is generated by the sensor (19) within a predetermined time interval. A suppression device (49) suppresses at least the first control pulse at the start of the training in order to prevent the training time measuring device from being started unintentionally by initially adjusting the handling part.

Description

Die Erfindung betrifft ein digitales Anzeigegeinstrument für ein Körpertrainingsgerät.The invention relates to a digital display instrument for a body training device.

Körpertrainingsgeräte, wie z.B. Rudergeräte oder Heim­fahrräder, haben einen Grundrahmen, an welchem ein für das Training gegen einen einstellbaren Widerstand sich bewegendes Handhabungsteil, beispielsweise zwei Ruder­griffe oder ein Tretkurbelpaar, beweglich geführt ist. Es ist bekannt, bei einem solchen Körpertrainingsgerät mittels eines an dem Grundrahmen angebrachten Sensors die Bewegung eines an dem Handhabungsteil befestigten Auslöseelements zu erfassen und mittels einer Auswerte­schaltung, die auf von dem Sensor erzeugte Steuerimpulse anspricht, Datensignale zu ermitteln, die die beim Training erbrachte Leistung repräsentieren. Die Daten werden auf einem Anzeigedisplay der Auswerteschaltung angezeigt.Body training devices, such as rowing machines or home bicycles, have a base frame on which a handling part which moves for training against an adjustable resistance, for example two rudder handles or a pair of pedal cranks, is movably guided. It is known in such a body training device to detect the movement of a trigger element attached to the handling part by means of a sensor attached to the base frame, and to determine data signals which represent the power provided during training by means of an evaluation circuit which responds to control pulses generated by the sensor . The data are shown on a display of the evaluation circuit.

Zu den die Trainingsleistung repräsentierenden Daten gehört insbesondere auch die Trainingszeit. Das Anzeigeinstrument sollte deshalb eine Zeitmeßeinrichtung umfassen, die in Echtzeit die tatsächliche Trainingszeit abzüglich etwaiger Pausen, d.h. diejenige Zeitspanne ermittelt, in welcher das Handhabungsteil tatsächlich bewegt wurde und der Sensor Steuerimpulse abgibt.The data representing the training performance in particular also includes the training time. The display instrument should therefore include a time measuring device that real-time the actual training time minus any breaks, i.e. determines the time span in which the handling part was actually moved and the sensor emits control pulses.

Es könnte daran gedacht werden, eine beispielsweise durch Start- und Stoptasten bedienbare Stoppuhr in dem Anzeigeinstrument vorzusehen. Dies hätte jedoch den Nachteil, daß beim Training die Stoppuhr fortlaufend bedient werden müßte.It could be considered to provide a stopwatch in the display instrument that can be operated, for example, by start and stop buttons. However, this would have the disadvantage that the stopwatch would have to be operated continuously during training.

Es ist Aufgabe der Erfindung, ein digitales Anzeige­instrument für ein Körpertrainingsgerät zu schaffen, welches die tatsächliche Trainingszeit selbsttätig ermittelt und darüber hinaus sicherstellt, daß Meß­fehler bei Inbetriebnahme des Körpertrainingsgeräts vermieden werden.It is an object of the invention to provide a digital display instrument for a body training device which automatically determines the actual training time and also ensures that measurement errors are avoided when the body training device is started up.

Diese Aufgabe wird durch die in Anspruch 1 angegebenen Merkmale gelöst. Das erfindungsgemäße Anzeigeinstrument weist eine auf Steuerimpulse des Sensors ansprechende Steuereinrichtung und eine im Start-Stop-Betrieb steuer­bare Trainingszeit-Meßeinrichtung auf, deren von dem Anzeigedisplay angezeigtes Signal die Trainingsechtzeit repräsentiert. Die Trainingszeit-Meßeinrichtung wird durch die bei Trainingsbeginn auftretenden Steuerimpulse gestartet. Die Steuereinrichtung stoppt die Trainings­zeit-Meßeinrichtung, wenn innerhalb eines Zeitintervalls vorgegebener Größe nach einem Steuerimpuls kein weiterer Steuerimpuls folgt. Auf diese Weise wird die Trainings­zeit nur dann gemessen, wenn das Handhabungsteil mit einer Geschwindigkeit bewegt wird, bei welcher die von dem Sensor erzeugten Steuerimpulse mit einer Periode kürzer als das vorgegebene Zeitintervall aufeinander­folgen. Die Größe des vorgegebenen Zeitintervalls richtet sich nach der Art des Körpertrainingsgeräts und ist beispielsweise bei einem Rudergerät entsprechend einer Mindest-Ruderschlagrate von zehn Schlägen pro Minute bemessen.This object is achieved by the features specified in claim 1. The display instrument according to the invention has a control device which responds to control pulses from the sensor and a training time measuring device which can be controlled in the start-stop mode and whose signal displayed on the display represents the real training time. The training time measuring device is started by the control impulses occurring at the beginning of the training. The control device stops the training time measuring device if no further control pulse follows a control pulse within a time interval of a predetermined size. In this way, the training time is only measured when the handling part is moved at a speed at which the control pulses generated by the sensor with a period consecutively shorter than the specified time interval. The size of the specified time interval depends on the type of body training device and, for example in the case of a rowing machine, is dimensioned according to a minimum rudder stroke rate of ten strokes per minute.

Normalerweise wird das Handhabungsteil des Trainings­geräts bewegt, während die trainierende Person auf dem Gerät für das nachfolgende Training Platz nimmt. Um Meßfehler der Trainingszeit-Meßeinrichtung, die durch diese anfängliche, oftmals unbeabsichtigte Bewegung hervorgerufen werden könnten, zu verhindern, unter­drückt die Steuereinrichtung bei gestoppter Trainings­zeit-Meßeinrichtung eine vorbestimmte Anzahl Steuer­impulse, was zu einer durch die Zahl der unterdrückten Steuerimpulse definierten Startverzögerung der Trainings­zeit-Meßeinrichtung führt. Anfängliche Steuerimpulse, wie sie beispielsweise bei der Inbetriebnahme des Trainingsgeräts auftreten können, lösen damit nicht die Trainingszeit-Meßeinrichtung aus. Der durch die Start­verzögerung eingeführte Meßfehler ist jedoch vernach­lässigbar, da die Trainingszeit-Meßeinrichtung um das von der Steuereinrichtung überwachte Zeitintervall über den letzten Steuerimpuls hinaus nachläuft und damit stets kleiner als dieses Zeitintervall ist.The handling part of the training device is normally moved while the exercising person sits on the device for the subsequent training. In order to prevent measurement errors of the training time measuring device, which could be caused by this initial, often unintentional movement, the control device suppresses a predetermined number of control pulses when the training time measuring device is stopped, which leads to a start delay of the training time measuring device defined by the number of suppressed control pulses leads. Initial control impulses, such as may occur when the training device is started up, do not trigger the training time measuring device. However, the measurement error introduced by the start delay is negligible, since the training time measuring device runs past the last control pulse by the time interval monitored by the control device and is therefore always smaller than this time interval.

Die Auswerteschaltung umfaßt in einer bevorzugten Aus­führungsform eine Impulsraten-Meßeinrichtung, deren von dem Anzeigedisplay angezeigtes Signal die Wiederholungs­rate der Steuerimpulse repräsentiert. Um zu verhindern, daß bei Trainingsbeginn ein durch die Inbetriebnahme verfälschter Wert angezeigt wird, ist zweckmäßigerweise auch hier vorgesehen, daß die Steuerschaltung bei gestoppter Trainingszeit-Meßeinrichtung eine vorbestimmte Anzahl Steuerimpulse unterdrückt und so für eine Meßver­zögerung sorgt.In a preferred embodiment, the evaluation circuit comprises a pulse rate measuring device, the signal of which is shown on the display display representing the repetition rate of the control pulses. In order to prevent a value falsified by the start-up from being displayed at the start of the training, it is also expedient here for the control circuit to suppress a predetermined number of control pulses when the training time measuring device is stopped, and thus to ensure a measurement delay.

Die Steuereinrichtung unterdrückt zweckmäßigerweise sowohl für die Trainingszeit-Meßeinrichtung als auch die Impulsraten-Meßeinrichtung den jeweils ersten, auf die anfängliche oder auch wiederholte Inbetriebnahme folgenden Steuerimpuls. Der Start der Trainingszeit-­Meßeinrichtung kann jedoch im Einzelfall auch nach dem Meßbeginn der Impulsraten-Meßeinrichtung liegen, bei­spielsweise dann, wenn den von der Auswerteschaltung zu ermittelnden Daten Steuerimpulspaare zugeordnet sind. So wird beispielsweise bei einem Rudergerät zur Verein­fachung der Konstruktion nicht die Bewegung der Ruder­handgriffe überwacht, sondern die Bewegung des bei einem solchen Gerät vorgesehenen Rollsitzes. Für jeden vollständigen Ruderschlag erzeugt der Sensor allerdings zwei Steuerimpulse. Um die Ruderschlagzahl mit der Trainingszeit in Übereinstimmung zu bringen, wird deshalb zweckmäßigerweise vorgesehen, daß zwar die Impulsraten-Meßeinrichtung mit dem zweiten Steuerimpuls nach Trainingsbeginn zu messen beginnt, die Trainings­zeit-Meßeinrichtung und ggf. eine die Zahl von Ruder­schlägen zählende Zähleinrichtung jedoch erst mit dem dritten Steuerimpuls gestartet wird.The control device expediently suppresses the first control pulse following the initial or repeated start-up both for the training time measuring device and the pulse rate measuring device. In individual cases, however, the start of the training time measuring device can also be after the start of the measurement of the pulse rate measuring device, for example when control pulse pairs are assigned to the data to be determined by the evaluation circuit. For example, in the case of a rowing machine to simplify the construction, it is not the movement of the rowing handles that is monitored, but rather the movement of the roller seat provided in such a machine. However, the sensor generates two control pulses for each complete oar stroke. In order to bring the number of strokes in line with the training time, it is therefore expediently provided that although the pulse rate measuring device begins to measure with the second control pulse after the start of the training, the training time measuring device and possibly a counting device counting the number of strokes only with the third control pulse is started.

Zum Rücksetzen ermittelter Daten kann eine durch eine Rücksetztaste betätigbare Rücksetzeinrichtung vorgesehen sein. Unbeabsichtigtes Löschen der Daten kann in diesem Zusammenhang verhindert werden, wenn Vorkehrungen ge­troffen sind, daß die Rücksetztaste über eine vorbestimm­te Zeitspanne, beispielsweise zwei Sekunden oder länger, betätigt werden muß.A reset device which can be actuated by a reset button can be provided for resetting determined data. In this context, accidental deletion of the data can be prevented if arrangements are made that the reset button has to be actuated for a predetermined period of time, for example two seconds or longer.

The pivoting movement of the rudder handles 7 is braked by adjustable, for example hydraulic, braking devices 9 with a predetermined resistance. A roller seat 11 is slidably guided on the longitudinal spars 1. For the training, the exercising person sits on the rolling seat 11 and is supported on the foot plates 13 with his feet while he moves the rudder handles 7. With each stroke of the oar, the roller seat 11 executes a back and forth movement.

An dem Grundrahmen ist ein digitales Anzeigeinstrument 15 in Sichtweite der trainierenden Person angebracht. Das Anzeigeinstrument hat eine nachfolgend noch näher erläuterte Auswerteschaltung, die über ein Kabel 17 mit einem an einem der Längsholme 1 angebrachten Sensor 19 verbunden ist. Der Sensor 19 ist als Magnetfeldsensor, beispielsweise als Reed-Schalter ausgebildet und spricht auf das Vorbeibewegen eines an dem Rollsitz angebrachten Magnets 21 an. Sowohl bei der Hinbewegung des Rollsitzes 11 als auch bei seiner Rückbewegung erzeugt der auf den Magnet 21 ansprechende Sensor 19 einen Steuerimpuls. Die Auswerteschaltung des Anzeigeinstruments spricht auf die Steuerimpulse an und ermittelt abhängig von den Steuerimpulsen die Gesamtzahl ausgeführter Ruderschläge, die momentane Ruderschlagfrequenz bzw. Ruderschlagrate und die tatsächliche Trainingszeit abzüglich etwaiger Pausen. Diese Daten werden an einem Anzeigedisplay 23 des Anzeigeinstruments 15 numerisch angezeigt.A digital display instrument 15 is attached to the base frame within sight of the exercising person. The display instrument has an evaluation circuit, which is explained in more detail below and is connected via a cable 17 to a sensor 19 attached to one of the longitudinal bars 1. The sensor 19 is designed as a magnetic field sensor, for example as a reed switch, and responds to the movement of a magnet 21 attached to the roller seat. The sensor 19, which responds to the magnet 21, generates a control pulse both during the forward movement of the roller seat 11 and during its return movement. The evaluation circuit of the display instrument responds to the control impulses and, depending on the control impulses, determines the total number of oar strokes executed. the current rudder stroke frequency or rudder stroke rate and the actual training time minus any breaks. These data are numerically displayed on a display 23 of the display instrument 15.

Die Figuren 2 und 3 zeigen Einzelheiten des Anzeigein­struments, welches abnehmbar in einem seinerseits an dem Grundrahmen des Rudergeräts befestigten Winkelhalter 25 gehalten ist. Das Anzeigeinstrument 15 hat hierzu auf der Außenseite seines Gehäuses 27 Nuten 29, in die an dem Winkelhalter 25 angeformte Rippen 31 eingreifen. Wie Figur 2 zeigt, hat das Gehäuse 27 mehrere Sätze solcher Nuten 29, um bei einer nachträglichen Ausrüstung des Rudergeräts mit dem Anzeigeinstrument in der Anord­nung des Winkelhalters 25 freie Wahl zu haben. Figur 3 zeigt, daß das Anzeigeinstrument auf seiner Vorderseite eine Rücksetztaste 33 hat, über die sämtliche anzuzei­genden Daten gelöscht werden können.FIGS. 2 and 3 show details of the display instrument, which is detachably held in an angle bracket 25, which in turn is attached to the base frame of the rowing machine. For this purpose, the display instrument 15 has 27 grooves 29 on the outside of its housing, into which ribs 31 formed on the angle holder 25 engage. As FIG. 2 shows, the housing 27 has several sets of such grooves 29 in order to have a free choice in the arrangement of the angle holder 25 when the rowing machine is retrofitted with the display instrument. FIG. 3 shows that the display instrument has a reset button 33 on its front, via which all the data to be displayed can be deleted.

Figur 4 zeigt ein Blockschaltbild der Auswerteschaltung des Anzeigeinstruments 15. Die Auswerteschaltung erlaubt die selbsttätige Ermittlung der tatsächlichen Trainings­zeit abzüglich etwaiger Pausen. Hierzu ist eine Trainings­zeit-Meßeinrichtung 35 mit einem periodische Taktimpulse einer Taktschaltung 37 zählenden Zähler 39 vorgesehen, dessen Zählinhalt ein Maß für die in Echtzeit abgelaufene Trainingszeit ist und in einem Anzeigefeld 41 des Anzeigedisplays 23 (Figur 1) angezeigt wird. Die Trainings­zeit-Meßeinrichtung 35 ist im Start-Stop-Betrieb steuerbar und wird durch einen an einem Starteingang 43 der Takt­schaltung 37 zugeführten Steuerimpuls des auf den Magnet 21 ansprechenden Sensors 19 gestartet. Eine auf die Steuerimpulse des Sensors 19 ansprechende Abschalte­einrichtung 45 (beispielsweise in Form eines durch die Steuerimpulse retriggerbaren Monoflops) liefert an einen Stopeingang 47 der Taktschaltung 37 ein Stopsignal, wenn innerhalb einer vorbestimmten Zeitspanne ΔT seit dem jeweils zuletzt aufgetretenen Steuerimpuls kein weiterer Steuerimpuls nachfolgt. Die Zeitspanne ΔT definiert eine vorbestimmte Mindest-Ruderschlagrate. Für eine Mindest-Ruderschlagrate von zehn Schlägen pro Minute müssen die sowohl bei der Hin- als auch der Herbewegung des Rollsitzes 11 (Figur 1) erzeugten Steuerimpulse in einer Zeitspanne ΔT von weniger als drei Sekunden aufeinanderfolgen. Die Trainingszeit-­Meßeinrichtung 35 wird damit gestoppt, wenn nicht oder mit einer Rate kleiner als die Mindest-Ruderschlagrate gerudert wird.Figure 4 shows a block diagram of the evaluation circuit of the display instrument 15. The evaluation circuit allows the actual determination of the actual training time minus any breaks. For this purpose, a training time measuring device 35 is provided with a counter 39 which counts periodic clock pulses from a clock circuit 37, the counting content of which is a measure of the training time which has elapsed in real time and is displayed in a display field 41 of the display 23 (FIG. 1). The training time measuring device 35 can be controlled in the start-stop mode and is started by a control pulse of the sensor 19 which responds to the magnet 21 and is supplied to a start input 43 of the clock circuit 37. A shutdown device 45, which responds to the control pulses from the sensor 19 (for example in the form of a monoflop that can be retriggered by the control pulses), supplies a stop signal to a stop input 47 of the clock circuit 37, if no further control pulse follows within a predetermined period of time .DELTA.T since the most recent control pulse. The time period ΔT defines a predetermined minimum rudder stroke rate. For a minimum rudder stroke rate of ten strokes per minute, the control impulses generated during both the back and forth movement of the roller seat 11 (FIG. 1) must follow one another in a time span ΔT of less than three seconds. The training time measuring device 35 is thus stopped when rowing is not taking place or at a rate lower than the minimum rudder stroke rate.

Um auf dem Rudergerät nach Figur 1 Platz nehmen zu können, muß die trainierende Person den Rollsitz 11 in aller Regel in eine seiner Endlagen bringen. Um zu verhindern, daß hierbei von dem Sensor 19 erzeugte Steuerimpulse bereits die Trainingszeit-Meßeinrichtung 35 starten, werden die Steuerimpulse dem Starteingang 43 über eine Unterdrückungseinrichtung 49, beispiels­weise in Form eines Schieberegisters, zugeführt. Das Schieberegister 49 hat im dargestellten Ausführungs­beispiel drei Stufen, wobei der Starteingang 43 an die dritte Stufe angeschlossen ist. Das Schieberegister 49 wird durch Stopsignale der Abschalteinrichtung 45 gelöscht, so daß bei Trainingsaufnahme die von dem Sensor 19 erzeugten Steuerimpulse schrittweise im Takt der erzeugten Steuerimpulse durch das Schieberegister 49 wandern müssen, bevor sie am Ausgang der dritten Stufe erscheinen und die Trainingszeit-Meßeinrichtung 35 starten können. Das Schieberegister 49 unterdrückt damit die ersten beiden Steuerimpulse. Während der erste unterdrückte Steuerimpuls durch eine unbeabsich­tigte Bewegung des Rollsitzes 11 hervorgerufen sein kann, wird durch den Start mittels des dritten Steuer­impulses sichergestellt, daß bereits eine vollständige Hin- und Herbewegung des Rollsitzes 11 stattgefunden hat und dementsprechend ein erster vollständiger Ruder­schlag.In order to be able to take a seat on the rowing machine according to FIG. 1, the exercising person must as a rule bring the roller seat 11 into one of its end positions. In order to prevent control pulses generated by the sensor 19 from starting the training time measuring device 35, the control pulses are fed to the start input 43 via a suppression device 49, for example in the form of a shift register. In the exemplary embodiment shown, the shift register 49 has three stages, the start input 43 being connected to the third stage. The shift register 49 is cleared by stop signals from the switch-off device 45, so that when the training is started, the control pulses generated by the sensor 19 must move through the shift register 49 step by step in time with the generated control pulses before they appear at the output of the third stage and the training time measuring device 35 starts can. The shift register 49 thus suppresses the first two control pulses. While the first suppressed control pulse can be caused by an unintentional movement of the roller seat 11, the start by means of the third control pulse ensures that a complete one Back and forth movement of the roller seat 11 has taken place and accordingly a first complete rudder stroke.

Die Auswerteschaltung ermittelt weitere, die Trainings­leistung repräsentierende Daten. Zur Ermittlung der Gesamtruderschlagzahl ist ein Zähler 51 vorgesehen, der über eine Teilerschaltung 53 jeden zweiten am Ausgang der zweiten Stufe des Schieberegisters 49 auftretenden Steuerimpuls des Sensors 19 zählt. Der Zählinhalt des Zählers 51 repräsentiert die Gesamtschlagzahl und wird in einem Anzeigefeld 55 des Anzeigedisplays 23 (Figur 1) numerisch angezeigt. Da dem Teiler 53 nach Aufnahme der Ruderbewegung bereits der zweite Steuerimpuls zugeführt wird, zählt der Zähler 51 synchron mit dem Start der Trainingszeit-Meßeinrichtung 35 den dritten Steuerimpuls als ersten Ruderschlag. Der Zähler 51 zählt damit Steuerimpulspaare entsprechend der mit jedem Ruderschlag ausgeführten Hin- und Herbewegung des Rollsitzes 11.The evaluation circuit determines further data representing the training performance. To determine the total number of rudder strokes, a counter 51 is provided, which counts, via a divider circuit 53, every second control pulse of sensor 19 occurring at the output of the second stage of shift register 49. The counting content of the counter 51 represents the total number of beats and is numerically displayed in a display field 55 of the display 23 (FIG. 1). Since the divider 53 is supplied with the second control pulse after the rudder movement has started, the counter 51 counts the third control pulse as the first rudder stroke synchronously with the start of the training time measuring device 35. The counter 51 thus counts pairs of control pulses in accordance with the back and forth movement of the roller seat 11 carried out with each oar stroke.

Die Auswerteschaltung ermittelt zwischen jeweils auf­einanderfolgenden Steuerimpulsen sowohl während der Hinbewegung als auch während der Rückbewegung des Rollsitzes 11 das dazu erforderliche Zeitintervall mittels eines periodische Taktimpulse einer Taktschal­tung 57 zählenden Zählers 59. Der Zählvorgang wird durch an einem Steuereingang 61 zugeführte Steuerim­pulse des Sensors 19 gesteuert. Die Steuerimpulse setzen den Zähler 59 zurück, nachdem sein das Zeit­intervall zwischen aufeinanderfolgenden Steuerimpulsen repräsentierender Inhalt in eine Recheneinrichtung 63 übernommen ist, die ihn in einen mathematisch inver­tierten, die momentane Ruderschlagrate repräsentie­renden Wert umrechnet. Der Wert der Ruderschlagrate wird in einem Anzeigefeld 65 des Anzeigedisplays 23 (Figur 1) angezeigt. Die durch das Schieberegister 49 gebildete Unterdrückungseinrichtung unterdrückt bei Trainingsbeginn jeweils den ersten Steuerimpuls, womit die Berechnung der Ruderschlagrate mit dem jeweils zweiten Steuerimpuls beginnt und beim dritten Steuer­impuls bereits der erste Ergebniswert der Ruderschlag­rate zugleich mit dem ersten Ergebniswert der Gesamt­schlagzahl in das Anzeigedisplay 23 übernommen werden kann.The evaluation circuit determines the time interval required between successive control pulses both during the forward movement and during the return movement of the roller seat 11 by means of a counter 59 counting periodic clock pulses from a clock circuit 57. The counting process is controlled by control pulses from the sensor 19 supplied to a control input 61. The control pulses reset the counter 59 after its content representing the time interval between successive control pulses is transferred to a computing device 63, which converts it into a mathematically inverted value representing the current rudder stroke rate. The value of the rudder stroke rate is displayed in a display field 65 of the display 23 (FIG. 1). The by the shift register 49 The suppression device formed suppresses the first control pulse at the start of the training, whereby the calculation of the rudder stroke rate begins with the second control pulse and, with the third control pulse, the first result value of the rudder stroke rate can be transferred to the display 23 at the same time as the first result value of the total stroke rate.

Sinkt die Ruderschlagrate unter die durch die Abschalt­einrichtung 45 festgelegte Mindest-Schlagrate ab, so wird nicht nur die Trainingszeit-Meßeinrichtung 35 gestoppt, sondern auch über einen Steuereingang 67 des die Ruderschlagrate numerisch anzeigenden Anzeigefelds 65 der Ruhewert, d.h. die Rate Null, angezeigt.If the rudder stroke rate falls below the minimum stroke rate determined by the switch-off device 45, not only the training time measuring device 35 is stopped, but also the control value 67 of the display field 65 numerically indicating the rudder stroke rate, i.e. the rate zero.

Das Schieberegister 49 und die Zähler 39, 51 und 59 sind mittels einer durch die Rücksetztaste 33 betätig­baren Rücksetzeinrichtung 69 rücksetzbar. Die Rücksetz­einrichtung 69 erzeugt ein Rücksetzsignal R, wenn die Rücksetztaste 33 für eine vorbestimmte Zeitspanne von beispielsweise zwei Sekunden betätigt wird. Die Überwa­chung der vorbestimmten Zeitspanne durch die Rücksetz­einrichtung 69 verhindert unbeabsichtigtes Löschen der in den Zählern 39, 51, 59 gespeicherten Daten.The shift register 49 and the counters 39, 51 and 59 can be reset by means of a reset device 69 which can be actuated by the reset button 33. The reset device 69 generates a reset signal R when the reset button 33 is operated for a predetermined period of time, for example two seconds. The monitoring of the predetermined time period by the reset device 69 prevents inadvertent deletion of the data stored in the counters 39, 51, 59.

Die vorstehend erläuterte Auswerteschaltung ist aus diskreten Bauelementen aufgebaut. Es versteht sich jedoch, daß die Auswerteschaltung auch durch einen Mikroprozesser mit einem in gleicher Weise wirkenden Programm realisiert sein kann.The evaluation circuit explained above is made up of discrete components. However, it goes without saying that the evaluation circuit can also be implemented by a microprocessor with a program acting in the same way.

Figur 5 zeigt ein weiteres Anwendungsbeispiel eines digitalen Anzeigeinstruments 15a in Verbindung mit einem Heimfahrrad bzw. Ergometer, bei welchem eine nicht näher dargestellte Bremseinrichtung über Tret­ kurbeln 71 angetrieben wird. Die Tretkurbeln 71 sind in üblicher Weise an einem mit einem Sitz 73 versehenen Grundrahmen 75 drehbar gelagert. Eine der Tretkurbeln 71 trägt einen Magnet 77, der bei der Kurbelbewegung an einem über ein Kabel 79 mit einer nicht näher darge­stellten Auswerteschaltung des Instruments 15a verbun­denen Magnetfeldsensor 81 vorbeibewegt wird. Der Magnet­feldsensor 81 ist an dem Grundrahmen 75 befestigt und erzeugt Steuerimpulse, auf die die Auswerteschaltung anspricht, wie dies vorstehend anhand der Figuren 1 bis 4 erläutert wurde. Insbesondere umfaßt die Auswerte­schaltung eine selbsttätig startende und stoppende Trainingszeit-Meßeinrichtung und eine die Steuerimpuls­rate und damit die Pedaldrehzahl ermittelnde weitere Meßeinrichtung. Die beiden genannten Einrichtungen können die anhand der Figur 4 erläuterte Schaltung haben. Um unbeabsichtigtes Starten der Trainingszeit-­Meßeinrichtung zu verhindern, ist ebenfalls eine Ein­richtung zur Unterdrückung des bei Trainingsbeginn erzeugten ersten Steuerimpulses vorgesehen.FIG. 5 shows a further application example of a digital display instrument 15a in connection with a home bicycle or ergometer, in which a braking device (not shown in detail) is pedaled crank 71 is driven. The pedal cranks 71 are rotatably mounted in a conventional manner on a base frame 75 provided with a seat 73. One of the pedal cranks 71 carries a magnet 77, which during the crank movement is moved past a magnetic field sensor 81 connected via a cable 79 to an evaluation circuit of the instrument 15a (not shown). The magnetic field sensor 81 is fastened to the base frame 75 and generates control pulses to which the evaluation circuit responds, as was explained above with reference to FIGS. 1 to 4. In particular, the evaluation circuit comprises an automatically starting and stopping training time measuring device and a further measuring device determining the control pulse rate and thus the pedal speed. The two devices mentioned can have the circuit explained with reference to FIG. 4. In order to prevent the training time measuring device from starting unintentionally, a device for suppressing the first control pulse generated at the start of the training is also provided.
