Description

Roller mit höhenverstellbarem Lenker und  Scooter with adjustable handlebars and
höhenverstellbarer Lenker  adjustable handlebar
Die Erfindung betrifft einen Roller, insbesondere einen Klapp roller mit höhenverstellbarem Lenker sowie einen entsprechen den höhenverstellbaren Lenker. The invention relates to a scooter, in particular a folding scooter with a height-adjustable handlebar and a corresponding to the height-adjustable handlebar.
Roller sind aus dem Stand der Technik bekannt. Sie weisen in der Regel zwei Achsen mit jeweils einer Bodenlaufrolle auf, zwischen denen ein Trittbrett angeordnet ist. Eine der Boden laufrollen ist über einen Lenker, dessen Lenkstange durch eine im fahrbereiten Zustand des Rollers im Wesentlichen senkrecht zum Trittbrett nach oben ragende Lenksäule geführt ist, lenk bar. Der Lenker erstreckt sich in der Regel mit seinen Griffen zu beiden Seiten der Lenkstange und ist häufig über einen Te leskopmechanismus höhenverstellbar, um an den jeweiligen Fah rer angepasst werden zu können. Der Lenker kann mit einer Schraubklemme oder einem Schnellspanner in der gewünschten Höhe fixiert werden. Scooters are known from the prior art. They usually have two axles, each with a floor roller, between which a running board is arranged. One of the floor rollers is steerable via a handlebar, the handlebar of which is guided by a steering column which projects upward substantially perpendicularly to the footboard when the scooter is ready to drive. The handlebar generally extends with its handles on both sides of the handlebar and is often height-adjustable via a telescopic mechanism in order to be able to be adapted to the respective driver. The handlebar can be fixed at the desired height with a screw clamp or a quick release.
Weiterhin sind Klapproller bekannt, die von einer den nicht klappbaren Rollern vergleichbaren Konfiguration mithilfe eines oder mehrerer Klapp- und Teleskopmechanismen in einen platz sparenden Transport- und Aufbewahrungszustand zusammengeklappt werden können. Furthermore, folding scooters are known which can be folded into a space-saving transport and storage state by means of one or more folding and telescopic mechanisms by a configuration comparable to the non-folding scooters.
Über einen ersten Klappmechanismus kann bspw. die Lenksäule mit dem darin geführten Lenker in eine Position verschwenkt werden, in welcher die Lenksäule im Wesentlichen parallel zum Trittbrett liegt. Using a first folding mechanism, for example, the steering column with the handlebar guided therein can be pivoted into a position in which the steering column lies essentially parallel to the footboard.
Damit der Lenker im zusammenklappten Zustand nicht oder zumin dest nicht unnötig über das Trittbrett hinausragt, wird regel- mäßig die Höhenverstellung der Lenksäule genutzt, um den Len ker vor oder nach dem Zusammenlegen in die niedrigste Höhe zu verfahren . To ensure that the handlebar does not protrude or at least does not protrude unnecessarily from the footboard when folded, moderately used the height adjustment of the steering column to move the steering arm to the lowest height before or after folding.
Entsprechende Teleskopmechanismen aus dem Stand der Technik werden in der Regel über eine Schnellspannverbindung zumindest im fahrbereiten Zustand des Rollers gesichert. Das Lösen und Anziehen entsprechender Schnellspannverbinder erfordern jedoch häufig einen nicht unerheblichen Kraftaufwand. Corresponding telescope mechanisms from the prior art are generally secured via a quick-release connection, at least when the scooter is ready to drive. However, loosening and tightening the corresponding quick-action connector often requires considerable effort.
Aufgabe der vorliegenden Erfindung ist es, einen Roller, ins besondere einen Klapproller und einen Lenker, zu schaffen, bei dem die Nachteile aus dem Stand der Technik nicht mehr oder nur noch in vermindertem Umfang auftreten. The object of the present invention is to create a scooter, in particular a folding scooter and a handlebar, in which the disadvantages of the prior art no longer occur or only to a reduced extent.
Gelöst wird diese Aufgabe durch einen Roller gemäß dem Haupt anspruch sowie einen Lenker gemäß dem nebengeordneten An spruch. Vorteilhafte Ausführungen sind Gegenstand der abhängi gen Ansprüche . This task is solved by a scooter according to the main claim and a handlebar according to the secondary claim. Advantageous designs are the subject of the dependent claims.
Demnach betrifft die Erfindung einen Roller umfassend ein zwi schen zwei Achsen mit jeweils wenigstens einer Bodenrolle an geordnetes Trittbrett und einen mit dem Trittbrett verbundenen Lenker für eine der beiden Achsen, wobei der Lenker zur Höhen verstellung teleskoprohrartig mit einem äußeren Führungsrohr mit Auszug am von der gelenkten Achse entfernten Ende und ei nem darin geführten, herausziehbaren inneren Rohr ausgestaltet ist, wobei am Auszug des Führungsrohrs eine Arretierung vorge sehen ist, wobei das innere Rohr gegenüber dem Führungsrohr verdrehgesichert ist und an wenigstens einer Seite in Richtung der Längsachse voneinander beabstandete Querrillen vorgesehen sind, und wobei die Arretierung ein federvorgespanntes Ras telement zum Eingriff in die Querrillen des inneren Rohrs und einen schwenkbaren Spannhebel zur wahlweisen Fixierung des Rastelements im Eingriff in eine Querrille des inneren Rohrs in einer ersten Position des Spannhebels aufweist. Accordingly, the invention relates to a scooter comprising an inter mediate two axles, each with at least one floor roller on an ordered footboard and a handlebar connected to the footboard for one of the two axles, the handlebars being telescopically height-adjustable with an outer guide tube with an extension on the steered by the Axle distal end and ei nem guided, pull-out inner tube is configured, wherein a lock is provided on the pull-out of the guide tube, the inner tube is secured against rotation with respect to the guide tube and transverse grooves spaced apart from one another in the direction of the longitudinal axis are provided, and wherein the locking means a spring-loaded Ras telement for engaging in the transverse grooves of the inner tube and a pivotable clamping lever for optionally fixing the Has locking element in engagement in a transverse groove of the inner tube in a first position of the clamping lever.
Weiterhin betrifft die Erfindung einen höhenverstellbaren Len ker für Fahrzeuge mit einem äußeren Führungsrohr mit Auszug an einem Ende und einem darin teleskoprohrartig geführten, her ausziehbaren inneren Rohr, wobei am Auszug des Führungsrohrs eine Arretierung vorgesehen ist, wobei das innere Rohr gegen über dem Führungsrohr verdrehgesichert ist und an wenigstens einer Seite in Richtung der Längsachse am inneren Rohr vonei nander beabstandete Querrillen vorgesehen sind, und wobei die Arretierung ein federvorgespanntes Rastelement zum Eingriff in die Querrillen des inneren Rohrs und einen schwenkbaren Spann hebel zur wahlweisen Fixierung des Rastelements im Eingriff in eine Querrille des inneren Rohrs in einer ersten Position des Spannhebels aufweist. Furthermore, the invention relates to a height-adjustable Len ker for vehicles with an outer guide tube with a pull-out at one end and a telescopic tube-guided, extendable inner tube therein, wherein a lock is provided on the pull-out of the guide tube, the inner tube being secured against rotation against the guide tube and on at least one side in the direction of the longitudinal axis on the inner tube of mutually spaced transverse grooves are provided, and wherein the locking means a spring-loaded locking element for engaging in the transverse grooves of the inner tube and a pivotable clamping lever for optionally fixing the locking element in engagement in a transverse groove of the inner tube in a first position of the clamping lever.
Bei dem erfindungsgemäßen Roller wird die Arretierung des Len kers nicht (oder zumindest nicht ausschließlich, siehe unten) über einen Kraftschluss erreicht, sondern (wenigstens teil weise) durch einen Formschluss, nämlich zwischen dem Rastele ment der Arretierung und einer der am inneren Rohr vorgesehe nen Querrillen. Das innere Rohr weist dabei entlang der Längs achse mehrere voneinander beabstandete Querrillen auf, in wel che das Rastelement eingreifen kann. Die Federvorspannung des Rastelementes ist dabei so gewählt, dass sich das Rastelement bei fehlender Fixierung durch den Spannhebel bei Zug oder Druck auf das innere Rohr löst, um so den Lenker auf die ge wünschte Höhe einzustellen. Dabei lässt sich der Lenker zwar nur auf die über die Querrillen vorgegebenen Höhen einstellen, durch entsprechend hohe Anzahl und geringem Abstand der Quer rillen zueinander lässt sich die Höhe des Lenkers aber ausrei chend genau einstellen. Ist der Lenker auf die gewünschte Höhe eingestellt, kann das in Eingriff mit einer Querrille befind liche Rastelement in dieser Position durch den Spannhebel fi xiert werden, in dem dieser in seine erste Position ver- schwenkt wird, sodass der Lenker in der eingestellten Höhe verbleibt. Dabei ist zu beachten, dass für die Fixierung des Rastelementes durch den Spannhebel gegenüber einem In the scooter according to the invention, the locking of the core is not achieved (or at least not exclusively, see below) via a frictional connection, but (at least partially) by a positive connection, namely between the locking element of the locking element and one of the inner tube provided on the inner tube transverse grooves. The inner tube has a plurality of spaced-apart transverse grooves along the longitudinal axis, in which the locking element can engage. The spring preload of the locking element is chosen so that the locking element loosens in the absence of fixation by the tensioning lever in tension or pressure on the inner tube, so as to adjust the handlebar to the desired height. The handlebars can only be adjusted to the heights specified via the transverse grooves, but the height of the handlebars can be set sufficiently precisely by a correspondingly high number and small distance between the transverse grooves. The handlebar is at the desired height adjusted, the locking element in engagement with a transverse groove can be fixed in this position by the tensioning lever by pivoting it into its first position so that the handlebar remains at the set height. It should be noted that for the fixing of the locking element by the clamping lever against one
Schnellspanner aus dem Stand der Technik nur sehr geringe Kräfte aufgebracht werden müssen. State-of-the-art quick releases only have to apply very low forces.
Damit sichergestellt ist, dass das Rastelement grundsätzlich in die am inneren Rohr befindlichen Querrillen eingreifen kann, ist das innere Rohr gegenüber dem Führungsrohr „verdreh sicher", d. h. das innere Rohr lässt sich um seine Längsachse nicht gegenüber dem Führungsrohr verdrehen. Dies kann bspw. durch eine nicht-rotationssymmetrische Ausgestaltung des inne ren Rohrs bei ausreichender Führung durch die Arretierung und/oder beider Rohre, ggf. mit zusätzlicher Führung durch die Arretierung erreicht werden. In order to ensure that the locking element can basically engage in the transverse grooves located on the inner tube, the inner tube is "twist-proof" with respect to the guide tube, ie the inner tube cannot be twisted relative to the guide tube about its longitudinal axis. This can be done, for example, by a non-rotationally symmetrical configuration of the inner tube can be achieved with sufficient guidance by the locking device and / or both tubes, possibly with additional guidance by the locking device.
Es ist bevorzugt, wenn die Arretierung eine Einrastvorrichtung umfasst, in die der Spannhebel in seiner ersten Position ein rastet. Durch eine entsprechende Einrastvorrichtung wird der Spannhebel in seiner ersten Position gesichert, wodurch auch die momentan eingestellte Höhe des Lenkers gegen unbeabsich tigte Veränderung gesichert wird. It is preferred if the locking device comprises a latching device into which the clamping lever engages in its first position. The tensioning lever is secured in its first position by means of a corresponding latching device, which also secures the currently set height of the handlebar against unintentional change.
Die Einrastvorrichtung kann einen zwischen Einrastposition und Freigabeposition verschiebbaren Sicherungsknopf und eine Feder zum Drängen des Sicherungsknopfes in die Einrastposition um fassen. Der Sicherungsknopf wird von der Feder grundsätzlich in die Einrastposition gedrängt, in welcher der in der ersten Position befindliche Spannhebel gegen unbeabsichtigtes Lösen gesichert ist. Soll der Spannhebel gelöst werden, um die Len- kerhöhe einzustellen, wird der Sicherungskopf in die Freigabe position verschoben, in der die Rastverbindung mit dem Spann hebel aufgehoben ist und dieser dann aus seiner ersten Posi tion herausbewegt werden kann. Ist der Spannhebel nicht mehr in seiner ersten Position, ist auch das Rastelement nicht mehr fixiert und die Höhe des Lenkers kann, wie beschrieben, ver stellt werden. The locking device can include a locking button that can be moved between the locking position and the release position and a spring for pushing the locking button into the locking position. The safety button is always pushed by the spring into the latching position, in which the tensioning lever in the first position is secured against unintentional loosening. If the tensioning lever is to be released in order to setting the ker height, the locking head is moved to the release position, in which the locking connection with the clamping lever is released and this can then be moved out of its first position. If the clamping lever is no longer in its first position, the locking element is no longer fixed and the height of the handlebar can, as described, be adjusted.
Auch wenn der Lenker in seiner Höhe bereits durch den be schriebenen Eingriff des Rastelements in eine der Querrillen an dem inneren Rohr grundsätzlich arretiert werden kann, ist es denkbar, dass aufgrund von Fertigungstoleranzen kleine, insbesondere seitliche Relativbewegungen des inneren Rohr ge genüber dem Führungsrohr möglich bleiben. Diese können die Fahrsicherheit des Rollers, zumindest aber das Fahrgefühl min dern. Um diese Relativbewegungen auszuschließen, ist bevor zugt, dass die Arretierung eine Schnellspannvorrichtung zur kraftschlüssigen Fixierung des inneren Rohres gegenüber dem Führungsrohr durch Klemmung umfasst, wobei der schwenkbare Spannhebel Teil der Schnellspannvorrichtung ist und die Even if the height of the handlebar can already be locked in principle by the engagement of the locking element in one of the transverse grooves on the inner tube, it is conceivable that small, in particular lateral, relative movements of the inner tube relative to the guide tube remain possible due to manufacturing tolerances , These can reduce the driving safety of the scooter, or at least the driving experience. In order to exclude these relative movements, it is preferred that the locking device comprises a quick-action clamping device for the frictional fixing of the inner tube relative to the guide tube by clamping, the pivotable tensioning lever being part of the quick-action clamping device and the
Schnellspannvorrichtung so ausgestaltet ist, dass der Kraft schluss zur Fixierung in der Stellung des Spannhebels in der ersten Position des Spannhebels erreicht wird. In andere Wor ten ist die erfindungsgemäße Arretierung der Lenkerhöhe durch das Rastelement durch eine Schnellspannvorrichtung ergänzt, mit der auch ggf. verbleibende Relativbewegungen der beiden Rohre des Lenkers ausgeschlossen werden. Auch wenn die Quick clamping device is designed so that the force circuit for fixing in the position of the clamping lever is achieved in the first position of the clamping lever. In other words, the locking of the handlebar height according to the invention by the locking element is supplemented by a quick release device, with which possibly remaining relative movements of the two tubes of the handlebar are excluded. Even if the
Schnellspannvorrichtung vergleichbar zu einer entsprechenden Einrichtung aus dem Stand der Technik ausgebildet sein mag, so muss diese aufgrund des Zusammenspiels von Rastelement und Qu errille sowie der Verdrehsicherheit des inneren Rohrs gegen über dem Führungsrohr nur deutlich weniger Kräfte aufnehmen, als wenn die Schnellspannvorrichtung allein das innere Rohr im Führungsrohr vollständig sichern müsste, wie dies im Stand der Technik der Fall ist. In der Folge ist die erforderliche Quick release device may be comparable to a corresponding device from the prior art, it only has to absorb significantly less forces than if the quick release device alone the inner tube due to the interaction of the locking element and transverse groove and the security against rotation of the inner tube relative to the guide tube would have to completely secure in the guide tube, as in the state of the Technology is the case. As a result, the required
Klemmkraft des Schnellspanners bei der Erfindung und damit auch die erforderliche Kraft zur Betätigung des Spannhebels deutlich geringer als im Stand der Technik, sodass die Höhen verstellung des Lenkers bei dem erfindungsgemäßen Roller auch in diesem Fall deutlich weniger Kraft erfordert als bei be kannten Rollern. Clamping force of the quick release in the invention and thus also the force required to actuate the clamping lever is significantly lower than in the prior art, so that the height adjustment of the handlebar in the scooter according to the invention also requires significantly less force in this case than with known scooters.
Es ist bevorzugt, wenn die Schnellspannvorrichtung hinsicht lich ihrer Klemmkraft, vorzugsweise mithilfe einer Klemmmutter einstellbar ist. Zur Vorspannung des Rastelements in Richtung Querrillen kann eine Blattfeder vorgesehen sein. It is preferred if the quick release device is adjustable with regard to its clamping force, preferably with the aid of a clamping nut. A leaf spring can be provided to pretension the locking element in the direction of transverse grooves.
Die Erfindung entfaltet ihre Vorteile besonders bei Rollern, bei denen der Lenker regelmäßig in der Höhe verändert wird.The invention unfolds its advantages particularly in scooters in which the handlebars are regularly changed in height.
Dies ist insbesondere bei Klapprollern der Fall. Die Höhenver stellung des Lenkers wird dabei genutzt, um den Klapproller möglichst klein zusammenzulegen. This is particularly the case with folding scooters. The height adjustment of the handlebar is used to fold the folding scooter as small as possible.
Zur Erläuterung des erfindungsgemäßen Lenkers wird auf die vorstehenden Ausführungen verwiesen. To explain the handlebar according to the invention reference is made to the above statements.
Die Erfindung wird nun anhand einer vorteilhaften Ausführungs form unter Bezugnahme auf die beigefügten Zeichnungen bei spielhaft beschrieben. Es zeigen: The invention will now be described by way of example with reference to an advantageous embodiment with reference to the accompanying drawings. Show it:

Figur 1 in verschiedenen Zuständen. In Figur 1 ist ein erfindungsgemäßer Roller 1, genauer ein Klapproller gezeigt. Der Roller 1 umfasst zwei senkrecht zur Blattebene stehende Achsen 2 mit jeweils einer Bodenrolle 3. Die eine Bodenrolle 3 ist dabei drehbar an einem Ende eines Trittbretts 4 gelagert, während die andere Bodenrolle 3 an ei nem Lenker 10 gelagert ist. Der Lenker 10 ist drehbar in einer Lenksäule 5 geführt, womit die daran gelagerte Bodenrolle 3 lenkbar ist. Die Lenksäule 5 ist über ein Klappgelenk 6 mit dem Trittbrett 4 verbunden. Mithilfe des Klappgelenks 6 lässt sich der in Figur 1 im fahrbereiten Zustand gezeigte Roller 1 derart zusammenklappen, dass die Lenksäule 5 parallel zum Trittbrett 3 ausgerichtet ist. Figure 1 in different states. FIG. 1 shows a scooter 1 according to the invention, more precisely a folding scooter. The scooter 1 comprises two axes 2 perpendicular to the plane of the sheet, each with a bottom roller 3. The bottom roller 3 is rotatably mounted on one end of a footboard 4, while the other bottom roller 3 is mounted on a handlebar 10. The handlebar 10 is rotatably guided in a steering column 5, whereby the bottom roller 3 mounted thereon can be steered. The steering column 5 is connected to the footboard 4 via a folding joint 6. With the help of the folding joint 6, the scooter 1 shown in the ready-to-drive state can be folded together in such a way that the steering column 5 is aligned parallel to the running board 3.
Die an dem Trittbrett 4 gelagerte Bodenrolle 3 ist über einen elektrischen Radnabenmotor 7 angetrieben, der über eine in das Trittbrett 4 integrierte Batterie mit elektrischer Energie versorgt wird. The bottom roller 3 mounted on the running board 4 is driven by an electric wheel hub motor 7, which is supplied with electrical energy via a battery integrated in the running board 4.
Der Lenker 10 umfasst ein Führungsrohr 11 und ein darin tele skopartig und verdrehsicher geführtes inneres Rohr 12, welches sich am Auszug 13 am von der gelenkten Achse 2 entfernten Ende des Führungsrohrs 11 bei Bedarf herausziehen lässt, um so die Höhe des Lenkers 10 zu verändern. An dem Auszug 13 ist weiter hin eine Arretierung 20 vorgesehen, mit der sich der Lenker 10 in der gewünschten Höhe arretieren lässt. The handlebar 10 comprises a guide tube 11 and a telescopic inner tube 12 guided therein in a telescopic manner, which can be pulled out on the pull-out 13 at the end of the guide tube 11 remote from the steered axle 2, so as to change the height of the handlebar 10. A lock 20 is also provided on the pull-out 13, with which the handlebar 10 can be locked at the desired height.
Die Arretierung 20 wird nun anhand der Figuren 2a, b und 3a-d, in der sie in verschiedenen Zuständen gezeigt ist, näher er läutert . The lock 20 is now explained in more detail with reference to FIGS. 2a, b and 3a-d, in which it is shown in different states.
Die Arretierung 20 ist an dem Führungsrohr 11 befestigt und umfasst eine Rastrolle als Rastelement 21, die mithilfe einer Blattfeder 22 gegen das innere Rohr 12 vorgespannt ist. Das innere Rohr 12 weist an einer Seite in Richtung der Längsachse des Rohrs 12 voneinander beabstandete Querrillen 14 auf. Die Blattfeder 22 und die Ausgestaltung der Querrillen 14 sind so aufeinander abgestimmt, dass sich das innere Rohr 12 grund sätzlich teleskopartig aus dem Führungsrohr 11 herausziehen o- der in dieses hineinfahren lässt, womit letztendlich die Hö henverstellung des Lenkers 10 gewährleistet wird. The locking device 20 is fastened to the guide tube 11 and comprises a locking roller as the locking element 21 which is biased against the inner tube 12 with the aid of a leaf spring 22. The inner tube 12 faces on one side in the direction of the longitudinal axis of the tube 12 spaced apart transverse grooves 14. The leaf spring 22 and the configuration of the transverse grooves 14 are coordinated with one another in such a way that the inner tube 12 can in principle be telescopically pulled out of the guide tube 11 or into it, which ultimately ensures the height adjustment of the handlebar 10.
Um den Lenker 10 in einer gewünschten Höhe zu sichern, ist der um eine Schwenkachse 23 Spannhebel 24 vorgesehen, der in der in Figuren 2a und 3a dargestellten ersten Position das Ras telement 21 im Eingriff mit einer Querrille 14 fixiert, sodass der Lenker 10 grundsätzlich in seiner Höhe festgelegt ist. Ist der Spannhebel 24 in einer anderen Position (vgl. Figuren 2b, 3d) kann die Höhe des Lenkers 10 wie beschrieben verändert werden . In order to secure the handlebar 10 at a desired height, the tension lever 24 is provided about a pivot axis 23, which fixes the ras telement 21 in engagement with a transverse groove 14 in the first position shown in FIGS. 2a and 3a, so that the handlebar 10 is basically in its amount is fixed. If the tensioning lever 24 is in a different position (cf. FIGS. 2b, 3d), the height of the handlebar 10 can be changed as described.
Um den Spannhebel 24 in seiner ersten Position zu sichern, ist eine Einrastvorrichtung 25 umfassend einen zwischen Einrastpo sition und Freigabeposition verschiebbaren Sicherungsknopf 26 und eine Feder 27 zum Drängen des Sicherungsknopfes 26 in die Einrastposition vorgesehen. Wie in Figur 3a erkennbar, über lappt der Sicherungsknopf 26 in seiner Einsatzposition mit dem in der ersten Position befindlichen Spannhebel 24. Um den Spannhebel 24 zu lösen, muss zunächst der Sicherungsknopf 26 gegen die Federkraft der Feder 27 in die Freigabeposition ver schoben werden (Figur 3b), bevor der Spannhebel 24 aus der ersten Position bewegt werden kann (Figur 3c) . Sobald sich der Spannhebel 24 nicht mehr in der ersten Position befindet, kann der Sicherungsknopf 26 losgelassen werden, womit er sich auf grund der Feder 27 wieder in die Einrastposition verschiebt (Figur 3d) . Die Kontaktflächen von Spannhebel 24 und Siche rungsknopf 26 sind so ausgebildet, dass der Spannhebel 24 beim Zurückbewegen in die erste Position automatisch mit dem Siche rungsknopf 26 einrastet. Auch wenn durch die bereits beschriebenen Komponenten der Ar retierung 20 sowie die Verdrehsicherheit zwischen innerem Rohr 12 und Führungsrohr 11 bereits eine Sicherung des Lenkers 10 in der gewünschten Höhe gewährleisten, ist zusätzlich noch eine Schnellspannvorrichtung 28 zur kraftschlüssigen Fixierung des inneren Rohres 12 gegenüber dem Führungsrohr 12 durch Klemmung vorgesehen. Der bereits beschriebene schwenkbare Spannhebel 24 ist dabei Teil der Schnellspannvorrichtung 28, sodass die Schnellspannvorrichtung 28 zusammen mit der Fixie rung des Rastelementes 21 betätigt werden kann. Die grundsätz lich auf bekannte Weise ausgeführte Schnellspannvorrichtung 28 ist dabei so ausgestaltet, dass der Kraftschluss zur Fixierung in der ersten Position des Spannhebels 24 erreicht wird, also wenn die besagte Fixierung des Rastelementes 21 erreicht wird. Die Klemmkraft der Schnellspannvorrichtung 28 - und damit auch die zur Betätigung des Spannhebels 24 erforderliche Kraft - lässt sich über die Klemmmutter 29 einstellen. Dabei ist zu beachten, dass die Schnellspannvorrichtung 28 lediglich der weitergehenden Fixierung des inneren Rohres 12 gegenüber dem Führungsrohr 11 dient, um etwaige Relativbewegungen der beiden Rohre 11, 12 zueinander zu vermeiden. Die eigentliche Festset zung der Höhe des Lenkers 10 wird durch das Rastelement 21 er reicht. Auch eine Verdrehsicherung ist bereits gegeben. Da die Schnellspannvorrichtung 28 also nicht zur Festlegung der Len kerhöhe und zur Verdrehsicherung erforderlich ist, kann die Klemmkraft deutlich geringer gewählt werden als im Stand der Technik, bei dem die Schnellspannvorrichtung 28 sämtliche zwi schen innerem Rohr 12 und Führungsrohr 11 auftretenden Kräfte allein über einen Kraftschluss aufnehmen muss. In der Folge ist auch die zur Betätigung des Spannhebels 24 erforderliche Kraft deutlich geringer als im Stand der Technik. In order to secure the tensioning lever 24 in its first position, a latching device 25 comprising a locking button 26 which can be displaced between the latching position and the release position and a spring 27 for urging the locking button 26 into the latching position are provided. As can be seen in FIG. 3a, the securing button 26 overlaps in its operating position with the tensioning lever 24 in the first position. In order to release the tensioning lever 24, the securing button 26 must first be pushed into the release position against the spring force of the spring 27 (FIG 3b) before the tensioning lever 24 can be moved from the first position (FIG. 3c). As soon as the tensioning lever 24 is no longer in the first position, the securing button 26 can be released, whereby it moves back into the latching position due to the spring 27 (FIG. 3d). The contact surfaces of the clamping lever 24 and hedging button 26 are designed such that the clamping lever 24 automatically engages with the securing button 26 when moving back into the first position. Even if the already described components of the locking mechanism 20 and the security against rotation between the inner tube 12 and the guide tube 11 already ensure that the handlebar 10 is secured at the desired height, there is also a quick release device 28 for the non-positive fixing of the inner tube 12 relative to the guide tube 12 provided by clamping. The pivotable clamping lever 24 already described is part of the quick release device 28, so that the quick release device 28 can be actuated together with the fixation of the latching element 21. The quick release device 28, which is in principle known, is designed in such a way that the frictional connection for fixing in the first position of the tensioning lever 24 is achieved, that is, when said locking element 21 is reached. The clamping force of the quick release device 28 - and thus also the force required to actuate the tensioning lever 24 - can be adjusted via the clamping nut 29. It should be noted that the quick release device 28 only serves to further fix the inner tube 12 relative to the guide tube 11 in order to avoid any relative movements of the two tubes 11, 12 with respect to one another. The actual setting of the height of the handlebar 10 is sufficient by the locking element 21. An anti-rotation device is also already in place. Since the quick release device 28 is therefore not necessary to determine the len kerhöhe and to prevent rotation, the clamping force can be chosen significantly lower than in the prior art, in which the quick release device 28 all the forces between the inner tube 12 and guide tube 11 forces occurring solely via a frictional connection must record. As a result, the force required to actuate the tensioning lever 24 is also significantly less than in the prior art.
