Die gebräuchlichen Handpumpen für Fahrräder zeigen den Ubelstand, daß der Radfahrer sich beim Aufpumpen der Radreifen stark bücken muß und den Pumpengrifr nur mit einer Hand bewegen kann, da die andere Hand zum Festhalten der Pumpe benutzt werden muß.The common hand pumps for bicycles show the Ubelstand that the cyclist When inflating the wheel tires you have to bend down hard and only use the pump handle can move with one hand as the other hand is used to hold the pump must become.
Diese Übelstände zu beseitigen, ist Zweck der vorliegenden Erfindung, nach welcher dieTo eliminate these drawbacks is the purpose of the present invention, according to which the
ίο Pumpe so gebaut ist, daß sie auf den äußeren Umfang des Rades fest aufgesetzt und mit diesem so verbunden werden kann, daß der Radler aufrecht stehend die Pumpe mit beiden Händen bedienen kann.ίο Pump is built so that it works on the outside The circumference of the wheel can be firmly attached and connected to it in such a way that the cyclist is standing upright with the pump can use both hands.
Auf beiliegender Zeichnung ist die neue Pumpe in einer Ausführungsform in zwei Seitenansichten dargestellt.In the accompanying drawing, the new pump is in one embodiment in two Side views shown.
Die Pumpe hat im allgemeinen eine der den Handpumpen für Fahrräder übliche Bauart, bei der durch Auf- und Niederschieben der Hülse α über Hülse b die Luft angesaugt und in den Luftreifen g des Rades gedrückt wird.The pump is generally one of the usual hand pumps for bicycles, in which the air is sucked in and pushed into the pneumatic tire g of the wheel by pushing the sleeve α up and down over the sleeve b.
Der Pumpenschlauch d ist hier aber nicht, wie üblich, an dem Boden des Rohres b, sondern seitlich befestigt, während der freie Bodenteil mit einem federnden Bügel/ versehen ist, der über den Luftreifen g geschoben werden kann und sich auf ihm, ohne festgehalten zu werden, infolge seiner Federkraft festklemmt. Der dem Seitenstutzen c der Hülse b angefügte Luftschlauch d wird dann an das Luftventil e in bekannter Weise angeschraubt.The pump hose d is not, as usual, attached to the bottom of the tube b, but on the side, while the free bottom part is provided with a resilient bracket / that can be pushed over the pneumatic tire g and is on it without being held on are stuck due to its spring force. The air hose d attached to the side connection c of the sleeve b is then screwed onto the air valve e in a known manner.
Die Pumpe besitzt während der Kompressionsstöße ihr Widerlager an dem Rade, so daß nicht nur diese Stöße dann kräftiger und rascher als bisher ausgeführt werden, wenn mit einer Hand gearbeitet wird, sondern auch der letzte Teil der Pumparbeit mit beiden Händen verrichtet werden kann. Denn die Verbindung zwischen Pumpe und Luftreifen wird mit der fortschreitenden Pumpenarbeit fester, da der seinen Querschnitt vergrößernde Reifen sich mehr und mehr in den Federbügel einpreßt, und da es gerade der letzte Teil der Pumpenarbeit ist, der am meisten Anstrengung erfordert, ist es wünschenswert, für das Ende der Luftfüllung eine möglichst große Kraft zur Verfügung zu haben.The pump has its abutment on the wheel during the compression shocks, so that not only are these thrusts executed more powerfully and more quickly than before, when working with one hand, but also the last part of the pumping work can be done with both hands. Because the connection between pump and Pneumatic tires become stronger as the pump work progresses, because of its cross-section enlarged tires press themselves more and more into the spring clip, and since this is the last part of the pump work, which requires the most effort, it is desirable for the end of the air filling to have the greatest possible power available.
Nach beendeter Füllung wird der Pumpenschlauch d vom Ventil e abgeschraubt und dann die Pumpe mit dem Bügel f von dem Schlauch g abgezogen.After filling is complete, the pump hose d is unscrewed from the valve e and then the pump with the bracket f is pulled off the hose g.
