Abstract

The adjustable bicycle handlebar as in 2930206 has the handgrip (4) retaining elements (3,5) laterally adjustable relative to the central portion (2) of the handlebar. The handgrips may be carried on cylindrical tube ends (12) which are telescopically slidable in or on the ends of the tubular portion (2). The tubes (12 or 2) may have clamps (11) to secure them in the desired relative position. The tube ends (12) may be curved towards the handgrips.

Description

Verstellbarer Fahrradlenker Adjustable bicycle handlebar

Zusatz zur Patentanmeldung P 29 30 206.5 und zur Gebrauchsmusterhilfsanmeldung G 79 21 316.4.Addition to patent application P 29 30 206.5 and utility model auxiliary application G 79 21 316.4.

Gegenstand der Hauptanmeldung ist ein verstellbarer Bahrradlenker, der am Lenker-Mittelteil verstellbar angebrachte Griffteile aufweist, durch aeren Verstellung die Forr und damit die Verwendbarkeit des Lenkers in typischer Weise verandert werden können, und zwar insbesondere so, daß der Lenker wahlweise die bevorzugte orm eines Rennlenkers, eines Sportlenkers oder eines Tourenlenkers aufweist.The subject of the main application is an adjustable bicycle handlebar, which has adjustable handle parts attached to the middle part of the handlebar, by aeren Adjustment of the shape and thus the usability of the handlebars in a typical way can be changed, in particular so that the handlebars optionally the has preferred form of a racing handlebar, a sports handlebar or a touring handlebar.

In Rahmen der dadurch gegebenen Problematik liegt der vorliegenden Erfindung die zusätzliche Aufgabe zugrunde, den verstellbaren Lenker der Hauptanmeldung weiterhin so auszugestalten, daß der gegenseitige Abstand der Griffteile verändert werden kann. Eine solche Veränderung kann zunächst einmal dem Körperbau des jeweiligen Fahrers Rechnung tragen; inscesondere aber macht sie es möglich, die Griffweite dann in e erwünschten Maße zu verändern, wenn der Lenker nach der hauptanmeldung in die Stellung "Sportlenker" gebracht und dadurch die seitliche Ausladung der Griffteile gegenüber den Stellungen "Rennlenker" bzw. "Tourenlenker" vergrößert worden ist.The present one lies within the scope of the problem posed by this Invention is based on the additional object of the adjustable handlebars of the main application continue to be designed so that the mutual spacing of the handle parts changed can be. Such a change can first of all be the physique of the particular person Driver take into account; In particular, however, it makes it possible to use the reach then to change to the desired extent when the handlebars after the main registration brought into the "sports handlebar" position and thereby the lateral projection of the handle parts compared to the positions "racing handlebars" or "touring handlebars" has been enlarged.

Gelöst wird diese Aufgabe gemäß der weiteren Erfindung dadurch, da; die Halterungen der Griffteile an dem Lenker-Mittelteil seitwärts ein- und ausschiebbar angeordnet sind.This object is achieved according to the further invention in that; the holders of the handle parts on the handlebar middle part can be pushed in and out sideways are arranged.

Zweckmäßig sind dabei die Griffteile an zylindrischen Rohrstücken befestigt, die ihrerseits in den zylindrischen sndstücken des Lenker-Mittelteils ein- und ausschiebbar sind.The handle parts on cylindrical pipe sections are useful here attached, which in turn in the cylindrical end pieces of the handlebar middle part can be pushed in and out.

Mit Vorteil können aber auch die Griffteile an zylindrischen Rohrstücken befestigt sein, die ihrerseits ber den zylindrischen Endstücken des Lenker-Mittelteils verschiebbar sind. an ihnen können zweckmäßig zur Festlegung dienende Rohrschellen angeformt sein.However, the handle parts can also advantageously be attached to cylindrical Pipe pieces be attached, in turn via the cylindrical end pieces of the handlebar middle part are movable. on them can expediently serving for fixing pipe clamps be molded.

Um bei ausgesprochener Engstellung der Griffteile den ungehinderten Zugriff zu den Griffteilen zu erleichtern, ist des weiteren vorgesehen, daß die die Griffteile tragenden zylindrischen Rohrstücke an ihren die Griffteile tragenden Enden bogenform gekrümnt sind, wie dies auch bei nichtverstellbaren Rennlenkren im allgemeinen der Fall ist.In order to ensure that the handle parts are not obstructed when the handle parts are extremely narrow To facilitate access to the handle parts, it is also provided that the the handle parts carrying cylindrical pipe sections on their carrying the handle parts Ends are curved in an arc, as is the case with non-adjustable racing steering wheels is generally the case.

Dem Vorstehenden entsprechende Anordnungen sind in den Figuren 1 bis 3 dargestellt, die z.T. auch die in der Hauptanmeldung verwendeten Bezugszeichen aufweisen. Danach ist mit 1 der Vorbau des Lenkers beziffert, und mit 3 und 5 sind die nach der uauptanmeldung die Griffteile 4 verstell-Dar halternden Rohrschellen und Schrauben beziffert.Arrangements corresponding to the above are shown in FIGS 3, some of which also contain the reference numerals used in the main application exhibit. Then the stem of the handlebar is numbered with 1, and with 3 and 5 are after the uaupt application the handle parts 4 adjustable Dar holding pipe clamps and screws numbered.

In Fig. 1 tritt der Lenker-iglittelteil nach der Hauptanmeldung als ein zylindrisches Rohr 2 in Erscheinung, in das beiderseits jeweils ein die Griffteile 4 tragendes zylindrisches Rohrstück 12 einschiebbar ist. Diese Rohrstücke 12 werden in dem vom Vorbau 1 getragenen zylindrischen Rohr des Lenker-Mittelteils 2 durch Rohrschellen 11 festgeklemmt.In Fig. 1, the handlebar iglitteteil occurs after the main application as a cylindrical tube 2 in appearance, in each of which the handle parts on both sides 4 supporting cylindrical pipe section 12 can be inserted. These pipe pieces 12 are in the cylindrical tube of the handlebar middle part 2 carried by the stem 1 Pipe clamps 11 clamped.

In Fig. 2 dagegen werden die Griffteile 4 von zylindrischen Rohrstücken 13 getragen, die ihrerseits über den zylindrischein Endstücken des Lenker-Mittelteils 2 verschiebbar sind und an denen zur Festlegung dienende Rohrschellen 11a angeformt sind. Bei dieser Ausgestaltungsform sind im übrigen die die Griffteile 4 tragenden Enden der Rohrstücke 13 in der eise bogenförmig gekrümmt, wie dies vielfach auch bei nicht verstellbaren Rennlenkern der Fall ist. Dadurch werden Behinderungen des Zugriffs zu den Giiffteilen vermieten, wie sie - insbesondere bei ausgesprochener Engstellung - durch eine kantige Übergangsstelle unter Umständen verursacht werden könnte.In Fig. 2, however, the handle parts 4 of cylindrical pipe pieces 13 carried, in turn over the cylindrical in end pieces of the handlebar middle part 2 are displaceable and on which pipe clamps 11a serving to fix are formed are. In this embodiment, the handle parts 4 supporting are moreover Ends of the pipe sections 13 in the iron are curved in an arc, as is often the case is the case with non-adjustable drop bars. This will prevent disabilities of the Rent access to the Giifftteile as they - especially when pronounced Constriction - by an angular transition point under certain circumstances could be caused.

Eine solcher bogenförmiger Übergang findet sich auch bei der Ausgestaltungsvariante nach der Fig. 3, die jedoch im übrigen wieder die Merkmale der in Fig. 1 wiedergegebenen Ausgestaltungsform aufweist.Such an arcuate transition is also found in the design variant according to FIG. 3, which, however, again have the features of those shown in FIG Has embodiment.
