Abstract
Description
[0001] Bisher wird in der Fahrradfachwerkstatt die Spurhaltigkeit eines Fahrrades mit einer geraden Holzlatte geprüft. Dadurch kann keine Aussage über die Spurhaltigkeit des Fahrradrahmens und die Stellung der Laufräder zueinander gemacht werden. Genauere Überprüfungen können nur anhand des ausgebauten Fahrradrahmens beim Hersteller des selbigen auf einer teuren Rahmenrichtplatte durchgeführt werden. Desweiteren muß das Vorder- und das Hinterrad separat auf ihre mittige Zentrierung überprüft werden.[0001] Until now, bicycle workshops have used a straight wooden slat to check the tracking of a bicycle. This means that no statement can be made about the tracking of the bicycle frame and the position of the wheels in relation to one another. More precise checks can only be carried out by the manufacturer using the removed bicycle frame on an expensive frame straightening plate. In addition, the front and rear wheels must be checked separately for centering.
[0002] Dieses bisherige Verfahren ist sehr zeitintensiv, teuer und läßt keine zuverlässige Aussage über die Stellung beider Laufräder zueinander, was die Fahreigenschaften des Fahrrades wesentlich beeinflußt, zu.[0002] This previous method is very time-consuming, expensive and does not allow any reliable statement about the position of the two wheels in relation to each other, which significantly influences the riding characteristics of the bicycle.
[0003] Der Erfindung des Spurvermessungsgerätes für Fahrräder, nachfolgend als „Rahmenlaser" bezeichnet, liegt das Problem zugrunde, eine einfache, schnelle, kostengünstige und zuverlässige Möglichkeit zu schaffen ein Fahrrad komplett, ohne größere Demontagearbeiten, in der Fahrradwerkstatt zu vermessen und das Ergebnis zu dokumentieren, z.B. wegen eines Unfallschadens. Dies ist anhand der Fig.l und Fig.2 eingehend beschrieben.[0003] The invention of the track measuring device for bicycles, hereinafter referred to as "frame laser", is based on the problem of creating a simple, fast, cost-effective and reliable way to measure a bicycle completely in the bicycle workshop without major disassembly work and to document the result, e.g. due to accident damage. This is described in detail using Fig. 1 and Fig. 2.
[0004] Die Lösung dieser Aufgabe erfolgt durch die Merkmale von Schutzanspruch 1.[0004] This problem is solved by the features of claim 1.
[0005] Die abhängigen Ansprüche enthalten vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.[0005] The dependent claims contain advantageous embodiments and further developments of the invention.
[0006] Der „Rahmenlaser" 1 besteht aus einer Lichtquelle 3, welche durch Betätigung eines daran befindlichen Druckschalters 3/1 einen gebündelten Lichtstrahl 5 erzeugt, und einem Grundträger 1/1 für die Aufnahme der Lichtquelle 3.[0006] The "frame laser" 1 consists of a light source 3, which generates a bundled light beam 5 by actuating a pressure switch 3/1 located thereon, and a base carrier 1/1 for receiving the light source 3.
Dieser Grundträger 1/1 ist mit einem Aufhahmeprisma 1/3 und einer darin befindlichen Justiereinrichtung 1/4 für die Lichtquelle 3 versehen, welche nach der Justage dauerhaft versiegelt wird.This base support 1/1 is provided with a receiving prism 1/3 and an adjustment device 1/4 for the light source 3, which is permanently sealed after adjustment.
Desweiteren hat der Grundträger 1/1 eine Aufnahme zur Befestigung auf der Tretlagerachse, in Fig. 2 ist das am meisten benutzte Vierkantsystem dargestellt.Furthermore, the base carrier 1/1 has a mount for attachment to the bottom bracket axle; the most commonly used square system is shown in Fig. 2.
[0007) In einem aufwendigen Verfahren wird der Lichtstrahl 5 so ausgerichtet und die Lichtquelle 3 dauerhaft fixiert, daß der Lichtstrahl 5 senkrecht zur Tretlagerachse verläuft. Die Fehlerabweichung beträgt maximal 0,5 mm pro Meter.[0007) In a complex process, the light beam 5 is aligned and the light source 3 is permanently fixed so that the light beam 5 runs perpendicular to the bottom bracket axis. The error deviation is a maximum of 0.5 mm per meter.
[0008] Der Grundträger 1/1 ist eine entsprechend umgearbeitete linke Tretkurbel.[0008] The base support 1/1 is a modified left crank.
Die Lichtquelle ist ein handelsüblicher Laserpointer mit entsprechender Lochblende zur Erzeugung eines feinen Lichtpunktes.The light source is a commercially available laser pointer with a corresponding pinhole aperture to produce a fine point of light.
[0009] Fig. 1 zeigt ein schematisiertes Fahrrad in Schrägansicht mit an der Tretlagerachse angebautem „Rahmenlaser" 1.[0009] Fig. 1 shows a schematic bicycle in oblique view with the "frame laser" 1 mounted on the bottom bracket axle.
Desweiteren sind 2 Meßvorgänge dargestellt, die jeweils den Abstand vom Laufrad 6 zu dem gebündelten Lichtstrahl 5 am Meterstab 4 zeigt.Furthermore, two measuring processes are shown, each showing the distance from the impeller 6 to the bundled light beam 5 on the meter stick 4.
[0010] Der „Rahmenlaser" 1 wird anstelle einer Tretkurbel, vorzugsweise der linken, auf der Tretlagerachse 2 befestigt.[0010] The "frame laser" 1 is attached to the bottom bracket axle 2 instead of a crank, preferably the left one.
-Nun wird der Meterstab an das Sitzrohr 7/4,unteres Drittel, angelegt und der Lichtstrahl 5 auf die Skalierung des Meterstabes 4 gerichtet, der Meßwert vom Meterstab 4 abgelesen und notiert.-Now the meter stick is placed on the seat tube 7/4, lower third, and the light beam 5 is directed onto the scale of the meter stick 4, the measured value is read from the meter stick 4 and noted.
Zu diesem Wert wird der Sitzrohrhalbmesser dazuaddiert.The seat tube radius is added to this value.
Dies ist die Entfernung vom Lichtpunkt zur Fahrradmittelebene und ist das Referenzmaß.This is the distance from the light point to the bicycle center plane and is the reference measurement.
-Jetzt kann an beliebiger Stelle des Rahmens, z.B. amSteuerrohr 7/2, am Unterrohr 7/3, an der Gabel 7.1, am Sitzrohr 7/4 oben und an den Hinterbauausfallenden 7/5 gemessen,und unter Berücksichtigung der entsprechenden Halbmesser die Abweichung zur Mittelebene des Fahrrades ermittelt werden.-Now you can measure anywhere on the frame, e.g. on the head tube 7/2, on the down tube 7/3, on the fork 7.1, on the top of the seat tube 7/4 and on the rear dropouts 7/5, and determine the deviation from the center plane of the bike, taking into account the corresponding radius.
-Durch messen an den Laufrädern in den Positionen 12:00,6:00 sowie 3:00 und 9:00, und der Berücksichtigung der halben Felgenbreite,kann die räumliche Lage der beiden Laufräder zueinander bestimmt werden.-By measuring the wheels in the positions 12:00, 6:00, 3:00 and 9:00, and taking into account half the rim width, the spatial position of the two wheels in relation to each other can be determined.
[0011] Die Halbmesser der Meßpunkte und die ermittelten Meßwerte werden in dem Spurmeßprotokoll dokumentiert.[0011] The radii of the measuring points and the measured values are documented in the track measurement protocol.
