Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Erfassung und Anzeige von Fahrradbetriebsdaten nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for Collection and display of bicycle operating data according to the preamble of claim 1.
Eine derartige Vorrichtung ist aus der DE 32 11 121 A1 bekannt.Such a device is known from DE 32 11 121 A1.
Der Stand der Technik, von der die Erfindung ausgeht ist der, daß die Trittfrequenzan zeige bei Fahrrädern heute überall durch eine induktive Impulser fassung am Kurbeltrieb gesondert ermittelt wird. Eine Ganganzeige als Display gibt es bis jetzt noch nirgends. Auch eine Meßeinheit für die relative Windgeschwindigkeit gibt es in diesem Zusammen hang noch nicht.The prior art from which the invention is based is that the cadence is show with bicycles everywhere today by an inductive impulse socket on the crank mechanism is determined separately. A gear indicator as a display there is still nowhere. Also a measuring unit for the relative wind speed there is this together don't hang yet.
Die gesonderte Trittfrequenzimpulserfassung hat unter anderem den Nachteil, daß sie die gewünschte Information erst nach Erfassung einiger Impulse die Frequenz errechnen kann. Eine Trittunterbre chung im Radfahrbetrieb ist aber häufig der Fall.The separate cadence pulse detection has among other things Disadvantage that they only get the desired information after acquisition a few pulses can calculate the frequency. A step However, cycling is often the case.
Die optische Erfassung der eingelegten Gänge am Schalthebel ist unzureichend, da sie über die im Eingriff befindlichen Überset zungsverhältnisse gar nichts aussagen und so bei einer ungünsti gen Kettenposition auch keine Schaltempfehlung gegeben werden kann.The optical detection of the gears engaged is on the gear lever inadequate as it translates over the engaged gear conditions say nothing at all and so in the case of an unfavorable No shift recommendation can be given for the chain position can.
Ohne die Anzeige der Windgeschwindigkeit ist eine aerodynamisch günstige taktische Formation nur schwer zu erreichen.Without the indication of the wind speed one is aerodynamic favorable tactical formation difficult to reach.
Der Anmeldung liegt die Aufgabe zugrunde, die bekannte Vor richtung zur Erfassung und Anzeige von Fahrradbetriebsdaten so auszubilden, daß die Anzeige der speziellen Fahrradbetriebsdaten unter Einsparung von Kabelverbindungen möglich ist.The registration is based on the task, the well-known before direction for collecting and displaying bicycle operating data see above train that the display of special bicycle operating data saving on cable connections is possible.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruches 1 angegebenen Merkmale gelöst. This task is performed by the in the characterizing part of claim 1 specified features solved.
Der Fahrradcomputer hat als wesentliche Neuerung eine Anzeige für die geschalteten Gänge, was die optimale Ritzelpositionierung er möglicht.The bike computer has a major innovation as an ad for the shifted gears what the optimal pinion positioning he possible.
Über diese Funktion läßt sich mittels der gefahrenen Geschwin digkeit die der aktuellen Übersetzung entsprechende Trittfrequenz ermitteln, womit eine zweite Impulsermittlung und Kabelführung eingespart werden kann.This function can be used by means of the driven speed the cadence corresponding to the current gear ratio determine what a second pulse determination and cable routing can be saved.
Die Erfassung der Information der Schaltpostition kann von durch die Stellung der Schalthebel induziert werden, die für jede Posi tion einen Kontakt haben, oder aber durch einen Schalter, der durch die Schaltkabel betätigt wird. Des weiteren ist eine Infor mationsermittlung direkt an Schaltwerk und Werfer möglich.The acquisition of the information of the switching position can be done by the position of the shift levers are induced for each Posi tion have a contact, or by a switch that is operated by the switching cable. Furthermore there is an information mation determination possible directly on the rear derailleur and projector.
Die Bedienung des Computers erfolgt durch eine oder mehrere Be dienungstasten, von denen aus die Anzeigemodi bzw. die Funktionen direkt von der Lenkerarmatur angesteuert werden können, ohne die Hand vom Lenker zu nehmen. Zur Bedienung dienen Knöpfe, die mit einer Schelle am Lenker befestigt und mit dem Computer verbunden sind.The computer is operated by one or more users control buttons from which the display modes or the functions can be controlled directly from the handlebar fitting without the Take your hand off the handlebar. The buttons are used for operation attached to the handlebar with a clamp and connected to the computer are.
Des weiteren bietet er als wichtige Funktion die Ermittlung der relativen Windgeschwindigkeit, was eine wesentliche Erleichterung im taktischen Wettbewerbsfahren bedeutet, da der momentane Luft widerstand ermittelt werden kann. Dazu befindet sich im Gehäuse des Gerätes eine Öffnung, mittels derer der Staudruck gemessen werden kann. Furthermore, it offers the determination of the as an important function relative wind speed, which is a significant relief in tactical competitive driving means because of the current air resistance can be determined. For this is located in the housing the device has an opening through which the dynamic pressure is measured can be.
Durch die Ermittlung und Verarbeitung des geschalteten Ganges im Rechenprozeß läßt sich die Trittfrequenz aus der gefahrenen Ge schwindigkeit ermitteln und anzeigen. So kann eine gesonderte Aufnahme der Trittfrequenzimpulse entfallen.By determining and processing the gear engaged in Computing process, the cadence can be determined from the ridden Ge determine and display speed. So a separate There is no need to record the cadence pulses.
Die Ermittlung des Winddrucks und die rechnerische Ermittlung der Relativgeschwindigkeit läßt eine optimale Kraftreserveeinteilung auf eine Strecke zu. Außerdem erwächst daraus ein großer Vorteil beim Windschattenfahren.The determination of the wind pressure and the calculation of the Relative speed leaves an optimal power reserve allocation towards a route. It also has a huge advantage when slipstreaming.
Die mit der Gangerfassung sinnvoll verbundene Verlagerung der Be dienungselemente des Computers aus der Lenkermitte in die Lenker griffarmaturen ermöglicht überhaupt erst die sichere Betriebsart. Die Anzeige der real gewählten Übersetzung oder des eingeschalte ten Ganges ermöglicht dem weniger geübten Fahrer einen sinnvollen Einsatz der zur Verfügung stehenden Gänge und eine Schonung von Kette und Ritzeln.The relocation of the Be Controls of the computer from the center of the handlebar into the handlebars Handle armatures enable safe operating mode in the first place. The display of the actually selected translation or the activated one ten Ganges enables the less experienced driver to make sense Use of the available gears and protection of Chain and sprockets.
Die Anzeige der Trittfrequenz steht unterbrechungsfrei stets zur Verfügung, solange das Fahrrad bewegt wird. Vorraussetzung ist eine Eingabemöglichkeit der den eingeschalteten Gängen entspre chenden Übersetzungen in den Computer. Eine zweite Impulserfas sung kann entfallen.The cadence display is always available without interruption Available as long as the bike is moved. Prerequisite is an input option corresponding to the gears engaged appropriate translations into the computer. A second momentum solution can be omitted.
