Description

Fahrradlenkstangen, die nach unten bzw. oben klappbar sind, sind seit langem bekannt. Hierbei war \-or allein beabsichtigt, die Lenkstangengrifle in eine dem Fahrer bequeme Lage zu bringen. Es haften diesen Konstruktionen aber Mängel an, die eine wesentliche Verteuerung bedeuten. Hierin ist auch der Grund zu sehen, daß sie nie zur Ausführung kamen und auf dem 'Markt erschienen.Bicycle handlebars that can be folded up or down have been around since known for a long time. The only intention here was to convert the handlebar grips into one to bring the driver to a comfortable position. However, there are defects in these constructions which mean a substantial increase in price. This is also the reason that they never came to fruition and appeared on the market.

Die Erfindung verfolgt hingegen ein anderes Ziel. Beim Abstellen von Fährrädern in engen Räumen, in Korridoren, beim Transport auf der Eisenbahn, beim Abstellen auf Fabrikhöfen in Abstellgestellen wird immer die Sperrigkeit und die Baubreite des Rades als störend empfunden. Durch die Erfindung ist es möglich, das Zwei- bis Dreifache an Rädern auf gleichem Raum unterzubringen. ' Weiterhin ist mit der Erfindung eine zweifache Diebstahlsicherung beabsichtigt. Sie besteht einmal in der Blockierung der Lenkbarkeit des Vorderrades. Dies wird dadurch erreicht, daß die beiden Lenkstangengriffe' i und 2 (Fig. 2) sich eng an das schräge Fahrradrahmenrohr bzw. bei sehr hoch gestellter Lenkstange an einen leicht anzubringenden Zwischensteg 3 anlegen. Dieser Zwischensteg ist > ,o ausgebildet, daß auch bei nach oben abgebogener Lenkstange diese Anlage erreicht wird. Eine weitere Sicherung wird dadurch erreicht, daß ein an einer Lenkstangenhälftc angebrachter Sperrhebel (Fig. i) zwischen die Speichen des Vorderrades greift. Hierdurch ist die Drehbarkeit des Vorderrades blockiert. Der Sperrliebel4 ist bei Nichtgebrauch an die Lenkstange anklappbar. In der nach unten geklappten Sperrstellung der Lenkstange werden die beiden Lenkstangenhälften durch zwei Schließstücke 5 und 6 (Fig. 2) mittels des Sperrbolzens eines Zahlen- oder Schlüsselschlosses gegen unberufenes Hochklappen fest miteinander verbunden. An Stelle des Zahlenschlosses 7 kann zwecks Verbilligung ohne Veränderung der Schließstücke in deren Bohrungen ein gewöhnliches Vorhängeschloß eingehängt werden. In fahrbereitem Zustand des Fahrrades, also bei hochgeklappten Lenkstangenhälften, werden diese durch einen Schraul>eitl>olzeii 8 mit dem Gabelkopf.i i. verbunden. Der Schraubenbolzen 8, dessen Kopf 9 nach unten in einen Konus ausläuft, greift in Aussparungen der inneren Lenkstangenhälften ein. Hierdurch werden diese auf die Mutterplatte io gepreßt. Durch diese Anordnung ist eine Sicherung gegen Lockerwerden während der Fahrt erreicht. Eine beispie'lsw-eiseAusführung zeigen Fig. i und 2.The invention, however, has a different aim. When parking bicycles in narrow spaces, in corridors, when transporting them on the railroad, when parking them on factory yards in parking racks, the bulkiness and the overall width of the bike are always perceived as annoying. The invention makes it possible to accommodate two to three times as many wheels in the same space. 'Furthermore, a double anti-theft device is intended with the invention. It consists on the one hand in blocking the steerability of the front wheel. This is achieved in that the two handlebar grips' i and 2 (FIG. 2) are placed close to the inclined bicycle frame tube or, when the handlebar is set very high, to an intermediate web 3 that is easy to attach. This intermediate web is > , o designed so that this system is achieved even when the handlebar is bent upwards. A further safeguard is achieved in that a locking lever (Fig. I) attached to a handlebar half engages between the spokes of the front wheel. This blocks the rotation of the front wheel. The Sperrliebel4 can be folded onto the handlebar when not in use. In the downwardly folded locking position of the handlebar, the two handlebar halves are firmly connected to each other by two strikers 5 and 6 (Fig. 2) by means of the locking pin of a number lock or key lock to prevent it from being folded up. Instead of the combination lock 7, an ordinary padlock can be hung in the holes in the bores for the purpose of making the strikers cheaper. When the bicycle is ready to drive, i.e. with the handlebar halves folded up, these are opened by a Schraul>eitl> olzeii 8 with the fork head. I i. tied together. The screw bolt 8, the head 9 of which tapers down into a cone, engages in recesses in the inner handlebar halves. As a result, these are pressed onto the mother plate io. This arrangement secures against loosening while driving. An exemplary embodiment is shown in FIGS. 1 and 2.
