Rückstrahler zur Befestigung an Fahrradspeichen Die Erfindung betrifft einen Rückstrahler zur Befestigung an Fahrradspeichen.Reflectors for attachment to bicycle spokes The invention relates to a reflector for attachment to bicycle spokes.

Bekannt sind Rückstrahler zur Befestigung an Fahrradspeichen, die Licht zurückwerfen, das im wesentlichen quer zum Fahrrad eintrifft. Sie haben wegen ihrer heftigen Bewegung einen hochwirksamen Signaleffekt.Reflectors for attachment to bicycle spokes are known Reflect light that arrives essentially across the bike. You have because of their violent movement a highly effective signaling effect.

Licht, das aus dem vorderen oder hinteren Bereich auf das Fahrrad trifft. wird von diesen Rückstrahlern nicht zurückgeworfen.Light emitted from the front or rear of the bike meets. is not reflected by these reflectors.

Der Erfindung liegt die Aufgabe zugrunde. diese Rückstrahler so auszubilden, daß dieser hochwirksame Signaleffekt in jede Richtung wirkt.The invention is based on the object. to design these reflectors in such a way that that this highly effective signaling effect works in every direction.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Rückstrahler als räumlicher Körper ausgebildet ist, dessen ebene oder gekrümmte Oberfläche Licht in jeder Richtung zurückwirft.According to the invention, this object is achieved in that the reflector is designed as a spatial body, the flat or curved surface of which is light throws back in every direction.

Das hat den Vorteil, daß dieser hochwirksame Signaleffekt nach allen Richtungen wirkt.This has the advantage that this highly effective signal effect after all Directions works.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieDen: Die Bezugszeichen bedeuten: 1 Rückstrahlkörper 2 Grundfläche 3 Deckfläche 4, 5, 6, 7 geneigte Seitenflächen 8 Winkelbereich in den die Grund- bzw. Deckfläche zurückstrahlt 9 Winkelbereich in den die Seiten flächen zurückstrahlen 10 Befestigungselement 11 Fahrradreifen 12 Fahrradspeiche 13 Radnabe 14 Radachse Aufbau: Der Rückstrahlkörper 1 ist als Pyramidenstumpf ausgebildet.An embodiment is shown in the drawing and will Described in more detail below: The reference symbols mean: 1 reflector body 2 base area 3 top area 4, 5, 6, 7 inclined side areas 8 angular range in the base or top surface reflects back 9 angular range in which the side surfaces reflecting back 10 fastening element 11 bicycle tire 12 bicycle spoke 13 wheel hub 14 Wheel axle structure: The reflector body 1 is designed as a truncated pyramid.

Er hat die Grundfläche 2, die Deckfläche 3, die geneigten Seitenflächen 4, 5, 6, 7 (Figur 1, 2 u. 3). It has the base 2, the top surface 3, the inclined side surfaces 4, 5, 6, 7 (Figures 1, 2 and 3).

Anordnung am Rad: Der Rückstrahlkörper 1 ist so an den Speichen 12 angeordnet. Arrangement on the wheel: The reflector body 1 is in this way on the spokes 12 arranged.

daß seine Grundfläche 2 im rechten Winkel zur Radacnse 14 liegt (Figur 4). that its base 2 is at right angles to the Radacnse 14 (Fig 4).

Wirkungsweise: Die Grundfläche 2 und die Deckfläche 3 des Rückstrahlkörpers 1 werfen Licht zurück, das von der Seite auf das Fahrrad trifft. Sie decken die Winkelbereiche 8 ab. Die geneigten Seitenflächen 4, 5, 6, 7 werfen Licht zurück, das aus dem vorderen bt. hinteren Bereich auf das Fahrrad trifft. Sie decken die Winkelbereiche 9 ab. - Leerseite -How it works: The base surface 2 and the top surface 3 of the reflective body 1 reflect light that hits the bicycle from the side. They cover the angular ranges 8. The inclined side surfaces 4, 5, 6, 7 reflect light from the front bt. the rear area meets the bike. They cover the angular areas 9. - blank page -
