Beschreibung Technisches Gebiet Description Technical area
[0001 ] Die Erfindung betrifft einen Fahrradlenker mit Hohlräumen für die Geberzylinder hydraulischer Bremsen, wobei der Lenker so geformt ist, dass die rennradtypische Unterlenkerhaltung eingenommen werden kann. The invention relates to a bicycle handlebars with cavities for the master cylinder hydraulic brakes, wherein the handlebar is shaped so that the road bike typical Unterlenkerhaltung can be taken.
Stand der Technik State of the art
[0002] Hydraulische Fahrradbremsen sind aus dem Stand der Technik aus einer Vielzahl von Anwendungen und Variationen bekannt. Bei Mountainbikes sind die hydraulischen Scheibenbremsen die bevorzugte Art der Bremsen. Bei diesen Bremsen werden die Bremsgriffe, welche die Geberzylinder der hydraulischen Bremsen enthalten, mithilfe von Schellen an einem Mountainbikelenker befestigt. Es gibt ebenfalls Hydraulikbremsen für Rennräder, bei denen die Geberzylinder in den Bremsgriffen untergebracht sind. Diese Bremsgriffe werden mithilfe von Schellen an einem klassisch gebogenen Rennradlenker befestigt. Ausserdem sind Hydraulikbremshebel für klassische Zeitfahrradlenker bekannt, bei denen die Geberzylinder im Lenker integriert sind, aber diese Zeitfahrradlenker bieten keine Möglichkeit die Unterlenkerhaltung einzunehmen, eine Lenkerhaltung, welche die klassisch gebogenen Rennradlenker bieten. Hydraulic bicycle brakes are known in the art from a variety of applications and variations. On mountain bikes, the hydraulic disc brakes are the preferred type of brakes. With these brakes, the brake handles, which contain the master cylinders of the hydraulic brakes, are attached to a mountain bike handlebar with the help of clamps. There are also hydraulic brakes for racing bikes where the master cylinders are housed in the brake handles. These brake levers are attached to a classic curved road handlebar using clamps. In addition, hydraulic brake levers for classic time-trial handlebars are known in which the master cylinders are integrated in the handlebar, but these time-trial handlebars offer no way to take the lower-arm attitude, a handlebar posture, which offer the classic curved road handlebars.
[0003] Die bekannten Lenker für Fahrräder haben den Nachteil, dass die Geberzylinder nicht in Hohlräumen im Lenker untergebracht werden können, wenn gleichzeitig die Möglichkeit der Unterlenkerhaltung bestehen soll, eine Lenkerhaltung, welche die klassischen Rennradlenker mit ihren zwei Bögen bieten. The known handlebars for bicycles have the disadvantage that the master cylinder can not be accommodated in cavities in the handlebar, if at the same time the possibility of Unterlenkerhaltung should consist of a handlebar support, which offer the classic road handlebars with their two bows.
Darstellung der Erfindung Presentation of the invention
[0004] Aufgabe der Erfindung ist es, eine dem eingangs genannten technischen Gebiet zugehörenden Fahrradlenker zu schaffen, bei dem die Geberzylinder in Hohlräumen in den Lenkerenden untergebracht werden können und gleichzeitig die Möglichkeit besteht die Unterlenkerhaltung einzunehmen, eine Lenkerhaltung, welche die klassisch gebogenen Rennradlenker bieten. The object of the invention is to provide a the aforementioned technical field associated bicycle handlebar, in which the master cylinder can be accommodated in cavities in the bar ends and at the same time there is the possibility to take the lower arm position, a handlebar, which offer the classic curved road handlebars ,
[0005] Die Lösung der Aufgabe ist durch die Merkmale des Anspruchs 1 definiert. Gemäss der Erfindung sind die beiden Enden des Lenkers durch gebogene Lenkerrohre ausgebildet, welche den charakteristischen Kurvenverlauf einer Sigmoidkurve haben. The solution of the problem is defined by the features of claim 1. According to the invention, the two ends of the handlebar are formed by curved handlebar tubes which have the characteristic curve of a sigmoid curve.
[0006] Durch die Realisierung dieser, dem charakteristischen Kurvenverlauf einer Sigmoidkurve entsprechend gebogenen Lenkerenden, ergeben sich Rohröffnungen in Fahrtrichtung. Diese Hohlräume können die Geberzylinder für die Hydraulikbremsen aufnehmen. Durch die gebogenen Lenkerenden, welche Krümmungen aufweisen, die dem charakteristischen Kurvenverlauf einer Sigmoidkurve entsprechen, kann auch die Unterlenkerhaltung eingenommen werden, indem der Lenker in den Wendepunkten der gebogenen Lenkerenden oder in den unteren Krümmungen der gebogenen Lenkerenden gegriffen wird. In diesen Griffpositionen am Lenker können auch die Bremshebel gegriffen werden. Die Unterlenkerhaltung ist eine sehr ökonomische Haltung, weil der Fahrer eine kompakte Körperform einnimmt und dem Fahrtwind dadurch wenig Angriffsfläche bietet. Through the realization of this, the characteristic curve of a sigmoid curve corresponding bent handlebar ends, resulting tube openings in the direction of travel. These cavities can accommodate the master cylinder for the hydraulic brakes. By the curved handlebar ends, which have curvatures corresponding to the characteristic curve of a sigmoid curve, the lower linkage attitude can be taken by the handlebars is used in the inflection points of the bent bar ends or in the lower curves of the bent bar ends. In these handle positions on the handlebar and the brake levers can be used. The lower-arm attitude is a very economical attitude because the driver takes a compact body shape and the wind thus offers little attack surface.
[0007] Dem Fachmann ist klar, dass zur Optimierung der Ergonomie und/oder der Aerodynamik die Krümmungen der Lenkerenden nicht exakt dem Kurvenverlauf einer Sigmoidkurve entsprechen müssen, wie durch die Sigmoidfunktion The skilled person is clear that to optimize the ergonomics and / or aerodynamics, the curvatures of the handlebar ends do not have to correspond exactly to the curve of a sigmoid, as by the sigmoid function
1 gegeben, sondern die Krümmungen der Lenkerenden können lediglich den charakteristischen Kurvenverlauf einer Sigmoidkurve aufweisen, mit einer unteren Krümmung, einem Wendepunkt und einer oberen Krümmung. Die Lenkerenden weisen im Wesentlichen eine Sigmoidkurvenform auf. Die Lenkerenden müssen auch nicht zwingend symmetrisch sein. Die oberen Krümmungen durch deren Enden die Geberzylinder führen und an denen die Bremsgriffe angebracht sind und die unteren Krümmungen der beiden Lenkerenden können auch unterschiedlich stark gekrümmt sein. Die oberen Bögen können auch kürzer sein als die unteren Bögen oder umgekehrt. 1, but the curvatures of the bar ends can only have the characteristic curve of a sigmoid curve, with a lower curvature, a turning point and an upper curvature. The handlebar ends essentially have a sigmoidal curve shape. The bar ends do not necessarily have to be symmetrical either. The upper curves through the ends of the master cylinder lead and where the brake handles are mounted and the lower curves of the two bar ends can also be curved to different degrees. The upper bows can also be shorter than the lower bows or vice versa.
[0008] In Varianten dazu können alle oder auch nur einige der Krümmungen kantig ausgebildet sein. In variants to all or even some of the curvatures may be formed edged.
[0009] Die beiden Lenkerenden werden durch ein Lenkerrohr in Querrichtung verbunden. In der Mitte dieses Querrohrs wird der Vorbau befestigt. Das Querrohr muss nicht gerade sein, es kann nach vorne, nach hinten, nach unten oder nach oben geneigt sein. Die verschiedenen Neigungen können auch miteinander kombiniert werden. The two ends of the handlebars are connected by a handlebar tube in the transverse direction. In the middle of this cross tube, the stem is attached. The cross tube does not have to be straight, it can be tilted forwards, backwards, downwards or upwards. The different inclinations can also be combined with each other.
[0010] In einer besonders bevorzugten Variante ist das Querrohr nach vorne und nach unten geneigt. In a particularly preferred variant, the cross tube is inclined forward and downward.
[0011 ] Die Rohrdurchmesser des Lenkers können variabel sein. Typische Rohrdurchmesser sind 25.8mm, 26.0mm, 31.8mm oder 35.0mm. Die Rohre des Lenkers müssen nicht zwingend rund sein. Zur besseren Ergonomie oder Aerodynamik können die Rohre unterschiedliche Formen aufweisen. Die Rohre der Lenkerenden können oval geformt sein und das Querrohr kann die Form eines Tropfens oder eine Flügelform haben. The pipe diameter of the handlebar can be variable. Typical pipe diameters are 25.8mm, 26.0mm, 31.8mm or 35.0mm. The tubes of the handlebar need not necessarily be round. For better ergonomics or aerodynamics, the tubes may have different shapes. The tubes of the handlebar ends may be oval shaped and the cross tube may have the shape of a drop or a wing shape.
[0012] Dem Fachmann sind dazu noch andere Rohrdurchmesser oder Rohrformen bekannt. The person skilled in the art other pipe diameter or shapes are known.
