Der Erfindung liegt die Aufgabe zugrunde, ein Trainingsgerät der einleitend angegebenen Gattung zu schaffen, das dauerhaft ohne externe Stromquelle auskommt.Of the Invention is based on the object, a training device of the introductory specified genus to create that permanently without external power source gets along.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass die Welle einen elektrischen Generator antreibt, der die Stromquelle auflädt.These Task is inventively achieved in that the shaft drives an electric generator, which is the power source charging.
Die Erfindung beruht auf der zunächst überraschenden Er kenntnis, dass sich auf diese Weise der Leistungsbedarf der elektrischen Komponenten des Trainingsgeräts decken läßt, obwohl die Welle sich reversierend nur um einen Winkel von selten mehr als 90° und mit vergleichsweise niedriger Winkelgeschwindigkeit dreht.The Invention is based on the initially surprising He knows that in this way the power requirement of the electrical Components of the training device covers, though the wave reversing only at an angle of rarely more as 90 ° and rotates at a comparatively low angular velocity.
Vorzugsweise treibt die Welle den Generator über ein Übersetzungsgetriebe an (Anspruch 2). Das Getriebe kann aus einem einfachen Stirnzahnräderpaar bestehen. Alternativ kann ein mehrstufiges Zahnradgetriebe oder auch ein Zahnriemengetriebe verwendet werden.Preferably the shaft drives the generator over a transmission gear to (claim 2). The gearbox can be made from a simple spur gear pair consist. Alternatively, a multi-stage gear transmission or also a toothed belt transmission can be used.
Als Generator eignet sich besonders gut ein Schrittmotor mit nachgeschalteter Gleichrichtung (Anspruch 3). Geeignete Schrittmotortypen sind im Handel erhältlich und damit wesentlich preiswerter als ein speziell angefertigter Generator.When Generator is particularly well suited to a stepper motor with downstream Rectification (claim 3). Suitable stepper motor types are commercially available available and thus much cheaper than a custom-made Generator.
Der Welle kann ein Bewegungssensor zugeordnet sein (Anspruch 4), beispielsweise ein einfacher elektromechanischer Kontakt wie etwa ein berührungslos schaltender Reedkontakt, dessen Schaltspiele nach Verarbeitung in der elektrischen Schaltung auf dem Display numerisch oder grafisch als Anzahl der Streck- und Beugebewegungen oder Hübe wiedergegeben werden kann.Of the Wave may be associated with a motion sensor (claim 4), for example a simple electromechanical contact such as a non-contact switching reed contact whose switching operations after processing in the electrical circuit on the display numerically or graphically as Number of stretching and Beugebewegungen or strokes can be reproduced.
Vorzugsweise ist der Welle jedoch ein Drehwinkelgeber zugeordnet, dessen Ausgangssignale in der elektrischen Schaltung verarbeitet werden (Anspruch 5), in welchem Fall auf dem Display zusätzlich auch die Amplitude je Hub wiedergegeben werden kann.Preferably However, the shaft is associated with a rotary encoder whose output signals be processed in the electrical circuit (claim 5), in in which case on the display in addition also the amplitude per stroke can be reproduced.
Ein derartiger Drehwinkelgeber kann insbesondere aus zwei versetzt zueinander angeordneten Sensoren bestehen (Anspruch 6), die auf ein sich synchron mit der Welle bewegendes Muster, z.B. ein optisches Muster, ansprechen und in an sich bekannter Weise elektrische Signale liefern, aus denen sich sowohl der Drehwinkel als auch die Drehrichtung ermitteln lassen.One such a rotary encoder can in particular offset from each other by two arranged sensors consist (claim 6), which is synchronized to a moving pattern with the wave, e.g. an optical pattern and deliver electrical signals in a known per se, from which determine both the angle of rotation and the direction of rotation to let.
Insbesondere können die zwei Sensoren des Drehwinkelgebers Hallsensoren sein, die gegenüber den Zähnen eines mit der Welle drehfest verbundenen Zahnrades, versetzt um einen halben Teilungsschritt oder ein ungeradzahliges Vielfaches davon, angeordnet sind (Anspruch 7). Hallsensoren haben gegenüber anderen Sensoren, z.B. optischen Sensoren, den Vorteil eines wesentlich geringeren Energieverbrauches.Especially can the two sensors of the rotary encoder Hall sensors be compared to the tooth a rotatably connected to the shaft gear, offset a half division step or an odd multiple thereof, are arranged (claim 7). Hall sensors have over others Sensors, e.g. optical sensors, the advantage of a material lower energy consumption.
Des weiteren kann jedem Ventil ein Ventilstellungssensor zugeordnet sein (Anspruch 8). Die Ausgangssignale der Ventilstellungssensoren sind repräsentativ für die Größe des Widerstandes, den der Benutzer des Trainingsgeräts überwinden muss und können daher ebenfalls in der elektrischen Schaltung verarbeitet und in dem Display numerisch oder grafisch angezeigt werden.Of Furthermore, each valve can be assigned a valve position sensor be (claim 8). The output signals of the valve position sensors are representative for the Size of the resistance, which the user of the training device must overcome and therefore can also processed in the electrical circuit and in the display displayed numerically or graphically.
Der jeweilige Ventilstellungssensor kann insbesondere ein elektromechanischer Inkrementalgeber sein (Anspruch 9), der den Vorteil hat, dass er nahezu keine elektrische Leistung verbraucht.Of the particular valve position sensor can in particular an electromechanical Incremental be (claim 9), which has the advantage that he almost no electrical power consumed.
Mit höherer Genauigkeit läßt sich der von dem Benutzer des Trainingsgeräts in Bewegungsrichtung zu überwindende Widerstand durch Drucksensoren ermitteln, die den Druck in jedem der Arbeitsräume des Arbeitszylinders in ein proportionales elektrisches Signal umsetzen. Die Drucksensoren verursachen jedoch einen höheren Verbrauch an elektrischer Leistung als die Inkrementalgeber.With higher Accuracy can be that to be overcome by the user of the training device in the direction of movement Resistance by pressure sensors determine the pressure in each the workrooms convert the working cylinder into a proportional electrical signal. However, the pressure sensors cause a higher consumption of electrical Performance as the incremental encoder.
Vorzugsweise umfasst die elektrische Schaltung einen Mikroprozessor, der aus den Ausgangssignalen der Sensoren benutzungsabhängige Größen zur Anzeige auf dem Display errechnet (Anspruch 10).Preferably The electrical circuit includes a microprocessor made up of The output signals of the sensors are usage-dependent quantities for display on the display calculated (claim 10).
Insbesondere kann dieser Mikroprozessor aus den Ausgangssignalen der Sensoren die vom Benutzer aufgewandte Arbeit und die von ihm erzeugte Leistung errechnen und auf dem Display zur Anzeige bringen (Anspruch 11). Der hierzu erforderliche Algorithmus ist vergleichsweise einfach in den Mikroprozessor zu programmieren. Die Eichung der Anzeigen auf dem Display, z.B. in Wattstunden und Watt, ist mit hinreichender Genauigkeit empirisch möglich.Especially This microprocessor can use the output signals of the sensors The user-expended work and the power it generates calculate and bring to the display for display (claim 11). The required algorithm is relatively simple to program in the microprocessor. Calibration of the indications on the display, e.g. in watt-hours and watts, is with sufficient Accuracy empirically possible.
Für die elektrischen Komponenten des Trainingsgerätes werden möglichst stromsparende Ausführungen verwendet. Unter Berücksichtigung dessen, dass der Stromgenerator die Batterie des Trainingsgerätes nur während dessen Benutzung auflädt und die von dem Generator im Durchschnitt abgegebene Leistung begrenzt ist, ist es trotzdem wichtig, sicherzustellen, dass der elektrische Energieverbrauch der Komponenten bei unbenutztem Trainingsgerät so gering als möglich ist. Das läßt sich dadurch erreichen, dass der Drehwinkelgeber und gegebenenfalls weitere Komponenten mit nennenswertem Stromverbrauch die Versorgungsspannung aus der Stromquelle über einen gesteuerten Halbleiterschalter erhalten, dessen Steuereingang mit einem Ausgang des Generators verbunden ist und der durchlässig schaltet, sobald der Generator eine Spannung liefert (Anspruch 12). Des Weiteren empfiehlt sich die Verwendung eines (handelsüblichen) Mikroprozessors, der aus einem energiesparenden Ruhezustand erst dann in seinen Arbeitszustand geht, wenn an einem seiner Eingänge ein Signal eintrifft.For the electrical Components of the training device be possible energy-saving versions used. Considering that the power generator is the battery of the exerciser only while its use charges and limits the power delivered by the generator on average It is nevertheless important to ensure that the electrical Energy consumption of components in unused training device so low as possible is. That can be thereby achieve that the rotary encoder and optionally further Components with significant power consumption, the supply voltage from the power source via receive a controlled semiconductor switch whose control input is connected to an output of the generator and the permeable turns, as soon as the generator supplies a voltage (claim 12). Furthermore We recommend the use of a (commercially available) microprocessor, the from an energy-saving state of rest only then to its working state goes when at one of its inputs a signal arrives.
