Abstract

On the handlebar (11) of e.g. a so-called mountain bike, a brake lever (12) is formed as a handle bar grip, and is rotatably fitted on the bar (11). A rotary axis (13) of the brake lever and an axis (14) of the handlebar are coaxial. - The brake lever is T-shaped, and on the handlebar is an intermediate piece, fitted non-rotatably. On this intermediate piece supports a Bowden (RTM) draw sleeve (16). The brake section of the Bowden cable (17) is fixed to the brake lever (12). A counter bearing is fitted in the intermediate piece (15) for the Bowden draw sleeve, and a hole in the handlebar grip accommodates a brake cable nipple.

Description

Handbremsvorrichtung für Fahrräder mit einem oder zwei an einem Lenker angebrachten Bremshebeln.Hand brake device for bicycles with one or two brake levers attached to a handlebar.

Zweck der Erfindung ist die Verbesserung der bei Fahrrädern üblichen Handbremshebel.The purpose of the invention is to improve bicycles usual handbrake lever.

Es sind Handbremsvorrichtungen bei Fahrrädern bekannt, bei denen man zur Betätigung der Bremsen Finger vom Lenker nehmen muß, wodurch man den Lenker nicht mehr sicher in der Hand hat.Hand brake devices for bicycles are known where you can move the brakes fingers from Handlebar must take, so that you can no longer use the handlebar in your hand.

Es sind außerdem Handbremshebel bekannt geworden, bei denen man den Bremshebel mit nur 2 Fingern betätigen kann. Diese Bremshebel sind ebenfalls ungünstig, weil damit keine ausreichende Bremswirkung zu erreichen ist und der Lenker ebenfalls nicht mehr sicher in der Hand liegt. Aufgabe der Erfindung ist es deshalb einen Bremshebel aufzuzeigen, bei dem man beim Fahren und beim Bremsen selbst bei stärksten Fahrgrundunebenheiten den Lenker sicher in der Hand hat und außerdem die Bremskraft ausdauernd in genügendem Maße auf das Rad ausüben kann. Diese Aufgabe wird dadurch gelöst, daß die Bremshebel als Lenkergriffe ausgebildet und zur Bremsbetätigung gegenüber dem Lenker verdrehbar sind.There are also hand brake levers known which you can operate the brake lever with only 2 fingers can. These brake levers are also unfavorable because of that insufficient braking effect can be achieved and the handlebar is also no longer safe in the hand. The object of the invention is therefore a brake lever to demonstrate where you drive and brake the handlebars even in the case of the most extreme uneven driving surfaces has a firm grip and the braking power is persistent can exercise on the bike to a sufficient extent. This object is achieved in that the brake lever designed as handlebar grips and opposite for brake actuation the handlebars are rotatable.

Durch diese Anordnung hat man den Lenker jederzeit sicher im Griff, was die Fahrsicherheit erhöht. Außerdem können bei entsprechender Ausbildung des Bremshebels sehr große Kräfte auf die Bremsvorrichtung ausgeübt werden.With this arrangement, the handlebar is always safe under control, which increases driving safety. Furthermore can with appropriate training of the brake lever very large forces are exerted on the braking device.

In Ausgestaltung der Erfindung können die Achsen der Lenkerenden und die Drehachsen der Bremshebel koaxial zueinander angeordnet sein. Desweiteren kann der Bremshebel T-förmig ausgebildet sein.In an embodiment of the invention, the axes of the Handlebar ends and the axes of rotation of the brake levers coaxial be arranged to each other. Furthermore, the brake lever Be T-shaped.

Eine besonders vorteilhafte Griffposition bildet die Ausbildung des Griffes in U-Form (Fig. 2). A particularly advantageous handle position is the design of the handle in a U-shape ( FIG. 2).

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is in the drawing shown and will be described in more detail below.

Fig. 1 bezeichnet mit 11 den Lenker eines Geländefahrrades. Ein Bremshebel 12 ist als Lenkergriff ausgebildet. Der Bremshebel 12 ist auf dem Lenker 11 drehbar gelagert. Eine Drehachse 13 des Bremshebels 12 und eine Achse 14 des Lenkers sind koaxial zueinander angeordnet. Der Bremshebel 12 ist T-förmig ausgebildet. Auf dem Lenker ist ein Zwischenstück 15 drehfest angeordnet. An diesem stützt sich eine Bremsbowdenzughülle 16 ab. Der Bremszug des Bowdenzuges 17 ist an dem Bremshebel 12 befestigt. Fig. 1 denotes 11 the handlebar of an all-terrain bicycle. A brake lever 12 is designed as a handlebar grip. The brake lever 12 is rotatably mounted on the handlebar 11 . An axis of rotation 13 of the brake lever 12 and an axis 14 of the handlebar are arranged coaxially to one another. The brake lever 12 is T-shaped. An intermediate piece 15 is arranged on the handlebar in a rotationally fixed manner. A brake cable cover 16 is supported on this. The brake cable of the Bowden cable 17 is attached to the brake lever 12 .

Fig. 2 zeigt einen Bremshebel 12a in U-Form. Fig. 2 shows a brake lever 12 a in a U-shape.

Fig. 3 bezeichnet einen Schnitt (2) durch den Bremshebel nach Fig. 1+2. Ein Widerlager 20 für die Bowdenzughülle 16 befindet sich im Zwischenstück 15. Eine Bohrung, die sich im Griff 12 befindet, dient zur Aufnahme eines Bremszugnippels 19. Der Bowdenzug wird durch eine Nut 18 im Bremshebel bis zum drehfest angeordneten Widerlager 20 geführt. Fig. 3 represents a cross-section (2) by the brake lever of Fig. 1 + 2. An abutment 20 for the Bowden cable casing 16 is located in the intermediate piece 15 . A hole in the handle 12 serves to receive a brake cable nipple 19 . The Bowden cable is guided through a groove 18 in the brake lever up to the abutment 20 arranged in a rotationally fixed manner.
