Problems solved by technology

[0005] Although the position of the steering gear can be adjusted reliably by means of the connecting device and can be retrofitted into an existing bicycle in a simple manner, the connecting device consists of a certain number of parts whose manufacture and Machining tolerances lead to higher requirements and the associated costs
Furthermore, it has proven that the mode of operation of such connection means is not obvious / self-explanatory, which necessitates instructions for use, resulting in limited ease of use

Embodiment Construction

[0022] according to figure 1 , figure 2 and image 3 The front part of the bicycle 1 is formed with a frame tube 2 and a tubular fork 4 mounted in the frame tube so as to be rotatable about a rotation axis 3 . The fork rod is a component part of the front fork 5 in which the front wheel 6 is mounted. The upper end of the fork lever 4 is connected via a connecting device 7 , which will be described in more detail below, to a head part 8 on which a handlebar 10 is fixedly arranged via a steering nose 9 .

[0023] The fork shank 4 has a bore 11 , in which the lower end of the tube, hereinafter referred to as clamping socket 13 , is accommodated easily but almost seamlessly. The clamping socket 13 is formed with an inclined edge 14 against which a correspondingly inclined support edge 15 of the cylindrical clamping part 16 rests. The clamping part 16 has an outer diameter equal to the outer diameter of the clamping socket 13 . Furthermore, the clamping part 16 is connected t...

Abstract

Provided is a bicycle (1) which is equipped with a handlebar (10) that can be adjusted corresponding to a front fork (5). The handlebar and the front fork can be respectively connected with the bearing portions (54) of sliding rotary bearing members (13, 51), and can move on a common rotary axis (3). Each bearing portion (54) can be adjusted one of a using position (G) and a stopping position (P) correspsonding to movable performance of each bearing portion. The bearing portions stay in a clamping state or a free state via a detachable connecting device (7). The connecting device is equipped with a detachable clamping device (36). The clamping device is provided with an operation lever (33) which can be adjusted to a trigger position (A) or a clamping position (K). The bicycle is also provided with a protecting device (55) disposed on the connecting device. The protecting device can be adjusted to the clamping position (K) or the trigger position (A).

Description

technical field [0001] The present invention relates to a bicycle having a handlebar that is adjustable relative to the front fork. Background technique [0002] A bicycle is known from DE19837972B4 with a handlebar adjustable relative to the front fork and is known to have the following features: [0003] a) The handlebar and the front fork are each connected to a bearing point of a sliding rotary bearing, wherein the handlebar and the front fork can move on a common axis of rotation, the mobility of the bearing points relative to each other makes it possible to adjust to In one of the two end positions (use position and parking position). The bearing points of the sliding swivel bearing can be brought into a fixedly mutually tensioned state or a free state movable relative to each other by means of a releasable connection, wherein the handlebar is positioned relative to the front fork in two mutually substantially rotating positions. In one of the 90° end positions. The...
