Description

Für die Lichterzeugung an Fahrrädern verwendet man bekanntlich Dynamomaschinen, deren gerieftes Antriebsrad für die Zeit des Lichtbedarfs am Fahrradreifen läuft. Da ein Gleiten und Rutschen des Antriebsrads besonders bei nasser Witterung unvermeidlich ist, ist der Gummireifen an der Laufstelle des Antriebsrads einer Abnutzung unterworfen, auch wird durch die ungleiche Stromerzeugung ein Flackern des Lichtes verursacht. Mit einem abgenutztenAntriebsradwird auch keine volle Ausnutzung der elektrischen Energiequelle möglich sein, so daß das Licht nur schwach leuchtet.It is well known that dynamo machines are used to generate light on bicycles, whose grooved drive wheel runs on the bicycle tire for the time the light is required. Since sliding and slipping of the drive wheel is inevitable, especially in wet weather the tire is subject to wear and tear at the running point of the drive wheel, the uneven generation of electricity also causes the light to flicker. With a worn drive wheel, there is also no full use of the electrical Energy source be possible so that the light shines only weakly.

All diese Mängel sind nach der Erfindung dadurch behoben, daß der Gleitschutz aus einer elastischen, auf ihrem äußeren Umfang mit Riefen versehenen und über das Antriebsrad zu ziehenden konischen haubenförmigen Kappe besteht, die an ihrem offenen Ende einen nach innen vorspringenden Rand aufweist.All these shortcomings are eliminated according to the invention in that the Anti-skid made of an elastic, grooved on its outer circumference and to be pulled over the drive wheel conical dome-shaped cap which has an inwardly projecting edge at its open end.

In der Zeichnung ist der Gleitschutz im Zusammenwirken mit der Lichtmaschine und dem Laufmantel des Fahrrads dargestellt.In the drawing, the anti-skid is in interaction with the alternator and the running jacket of the bicycle.

Die Lichtmaschine a ist bekanntlich seitlich an der Gabel des Fahrrads gelenkig befestigt, so daß für die Zeit des Lichtbedarfs das Antriebsrad c in Berührung mit der Laufdecke b des Fahrrads gebracht werden kann. Damit nun der metallisch harte Angriff des Antriebsrads aufgehoben wird, stülpt man über das Antriebsrad c eine Gummikappe f, die auf ihrem äußeren Umfang mit Riefen versehen ist und unten einen Innenrand d aufweist. Damit nun aber beim Überstülpen und Ausdehnen der Kappe genügend Material vorhanden ist, ist die Kappe f zu einer Haube e ausgebildet. Kommt nun die Lichtmaschine, die man entsprechend dem etwas vergrößerten Umfang des Antriebsrads eingestellt hat, in Antriebsstellung, dann drückt das Gummiantriebsrad gegen den Laufgummi der Decke, und die Mitnahme des Antriebsrads ist gesichert. Man kann die federnde Anpressung des Antriebsrads stärker einstellen, ohne eine Beschädigung des Fahrrads hefürchten zu müssen.The alternator a is known to be on the side of the fork of the bicycle hinged so that the drive wheel c is in contact for the time the light is required can be brought with the tread b of the bicycle. So now the metallic hard attack of the drive wheel is lifted, one slips over the drive wheel c a rubber cap f which is grooved on its outer periphery and below has an inner edge d. But with that now when slipping over and expanding the cap If enough material is available, the cap f is formed into a hood e. Comes now the alternator, which one corresponds to the slightly enlarged circumference of the drive wheel has set, in the drive position, then the rubber drive wheel presses against the Running rubber of the ceiling, and the drive wheel is secured. You can Adjust the resilient pressure of the drive wheel to a greater extent without damaging it of having to fear the bike.

PATENTANSPRUCH: Gleitschutz für das Antriebsrad der elektrischen Lichtmaschine für Fahrräder, dadurch gekennzeichnet, daß der Gleitschutz aus einer elastischen, auf ihrem äußeren Umfang mit Riefen versehenen und über das Antriebsrad (c) zu ziehenden konischen haubenförmigen Kappe (f) besteht, die an ihrem offenen Ende einen nach innen vorspringenden Rand (d) aufweist. Zur Abgrenzung des Erfindungsgegenstands vom Stand der Technik ist im Erteilungsverfahren- folgende Druckschrift in Betracht gezogen worden: Schweizerische Patentschrift NTr. 93 i63. Claim: Anti- skid for the drive wheel of the electric alternator for bicycles, characterized in that the anti-skid consists of an elastic, grooved on its outer circumference and to be pulled over the drive wheel (c), conical hood-shaped cap (f), which at its open End has an inwardly projecting edge (d). To distinguish the subject matter of the invention from the state of the art, the following publication was considered in the granting procedure: Swiss patent specification NTr. 93 i63.
