In der Verstauposition können die Hohlräume der beiden Teile die Zylinder-Kolben-Einheit sowie einen mit der Zylinder-Kolben-Einheit verbundenen Schlauch aufnehmen.A pump of the aforementioned type is from the DE 801 125 C. known. The pump described therein comprises a pedal mechanism made of two parts that are movable relative to one another, between which a cylinder-piston unit for generating compressed air is arranged. The two parts each have a cavity on their mutually facing sides and can rest against one another in a stowed position. In the stowed position, the cavities of the two parts can accommodate the cylinder-piston unit and a hose connected to the cylinder-piston unit.

Eine weitere Pumpe ist aus der CH 276 022 A bekannt. Die darin beschriebene Pumpe umfasst ebenfalls einen Tretmechanismus aus zwei zueinander beweglichen Teilen, zwischen denen eine Zylinder-Kolben-Einheit zur Erzeugung von komprimierter Luft angeordnet ist. Die Pumpe umfasst weiterhin ein mit der Zylinder-Kolben-Einheit verbundenes Manometer.Another pump is out of the CH 276 022 A known.

The pump described therein also includes a pedal mechanism made of two parts that are movable relative to one another, between which a cylinder-piston unit for generating compressed air is arranged. The pump also includes a manometer connected to the cylinder-piston unit.

Eine weitere Pumpe ist aus der WO 2015/145443 A1 bekannt. Darin wird ein modulares System aus einer Tretpumpe und einem spiralförmig ausgebildeten Schlauch offenbart. Bei Pumpen dieser Art ist häufig der Platzbedarf des Schlauches ein Problem.Another pump is out of the WO 2015/145443 A1 known. It discloses a modular system consisting of a pedal pump and a spiral hose. With pumps of this type, the space requirement of the hose is often a problem.

Aufgabe der vorliegenden Erfindung ist daher die Schaffung einer Pumpe der eingangs genannten Art, bei der der Schlauch bei Nichtbenutzung platzsparend untergebracht werden kann oder wenig störend aufbewahrt werden kann.The object of the present invention is therefore to create a pump of the type mentioned at the outset, in which the hose can be accommodated in a space-saving manner when not in use or can be stored with little disruption.

Dies wird durch eine Pumpe der eingangs genannten Art mit den kennzeichnenden Merkmalen des Anspruchs 1 erreicht. Die Unteransprüche betreffen bevorzugte Ausgestaltungen der Erfindung.This is achieved by a pump of the type mentioned with the characterizing features of claim 1. The subclaims relate to preferred embodiments of the invention.

Gemäß Anspruch 1 ist vorgesehen, dass die Pumpe ein Manometer umfasst und dass die Aufnahmemittel einen Ringraum ausbilden, der sich um das Manometer herum erstreckt, wobei der Schlauch in der Verstauposition in dem Ringraum angeordnet ist und sich um das Manometer herum erstreckt. Dadurch wird der Schlauch platzsparend untergebracht und stört den Benutzer nicht.According to claim 1 it is provided that the pump comprises a pressure gauge and that the receiving means form an annular space which extends around the pressure gauge, the hose being arranged in the stowage position in the annular space and extending around the pressure gauge. This saves space for the hose and does not bother the user.

Es kann vorgesehen sein, dass sich der Schlauch in der Verstauposition in einer Mehrzahl von Schlaufen um das Manometer herum erstreckt. Der Schlauch kann beispielsweise derart in den Ringraum eingebracht werden, dass er einem Betrachter kaum auffällt. Weiterhin ist der Schlauch von dem Ringraum vergleichsweise gut und sicher aufgenommen, insbesondere wenn die Ringform den Schlaufen des Schlauches entspricht.It can be provided that the hose extends in a plurality of loops around the manometer in the stowed position. The hose can, for example, be introduced into the annular space in such a way that it is hardly noticeable to an observer. Furthermore, the hose is received comparatively well and safely by the annular space, especially if the ring shape corresponds to the loops of the hose.

Es besteht die Möglichkeit, dass der Tretmechanismus zwei Gehäuseteile umfasst, die schwenkbar aneinander angebracht sind, wobei durch eine Bewegung der beiden Gehäuseteile relativ zueinander die Zylinder-Kolben-Einheit betätigt wird. Dabei kann ein erstes der beiden Gehäuseteile ein Basisteil sein, das auf einem Boden aufstehen kann. Weiterhin kann vorgesehen sein, dass das zweite der beiden Gehäuseteile von einer ersten Stellung, in der es einen Winkel ungleich 0° und ungleich 180°, insbesondere einen Winkel zwischen 30° und 90° mit dem ersten Gehäuseteil einschließt, in eine zweite Stellung überführt werden kann, in der es zumindest teilweise auf dem ersten Gehäuseteil aufliegt.There is the possibility that the pedal mechanism comprises two housing parts which are pivotally attached to one another, the cylinder-piston unit being actuated by moving the two housing parts relative to one another. A first of the two housing parts can be a base part that can stand on a floor. It can further be provided that the second of the two housing parts has a first position in which it has an angle not equal to 0 ° and not equal to 180 °, in particular one Includes angles between 30 ° and 90 ° with the first housing part, can be transferred to a second position in which it lies at least partially on the first housing part.

Es kann vorgesehen sein, dass das zweite Gehäuseteil eine Aussparung aufweist, durch die sich das Manometer und/oder die Zylinder-Kolben-Einheit zumindest teilweise hindurcherstrecken können. Insbesondere kann dabei die Pumpe eine Abdeckung umfassen, die in der zweiten Stellung des zweiten Gehäuseteils die Aussparung des zweiten Gehäuseteils zumindest teilweise abdecken kann. Beispielsweise kann die Abdeckung an den Aufnahmemitteln angeordnet sein beziehungsweise sich von den Aufnahmemitteln wegerstrecken. Durch die Abdeckung kann sich eine optisch weitgehend geschlossene Oberfläche der Pumpe im nicht benutzten Zustand ergeben, so dass die Pumpe optisch aufgewertet wird. Weitere Merkmale und Vorteile der vorliegenden Erfindung werden deutlich anhand der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele unter Bezugnahme auf die beiliegenden Abbildungen. Darin zeigen:

Die abgebildete Ausführungsform einer erfindungsgemäßen Pumpe umfasst eine Zylinder-Kolben-Einheit 1, in der durch Bewegen eines Kolbens 2 in einem Zylinder 3 Luft zum Aufpumpen eines Zweiradreifens komprimiert werden kann. Die Pumpe umfasst weiterhin einen mit der Zylinder-Kolben-Einheit 1 verbundenen Schlauch 4, der spiralförmig ausgebildet ist. An dem von der Zylinder-Kolben-Einheit 1 abgewandten Ende des Schlauchs 4 ist ein Pumpenkopf 5 angeordnet, der Anschlussmittel 6, 7 für die Verbindung mit einem Ventil eines Zweiradreifens aufweist.The illustrated embodiment of a pump according to the invention comprises a cylinder-piston unit 1, in which air can be compressed to move a two-wheeled tire by moving a piston 2 in a cylinder 3. The pump further comprises a hose 4, which is connected to the cylinder-piston unit 1 and has a spiral shape. At the end of the hose 4 facing away from the cylinder-piston unit 1 there is a Pump head 5 arranged, which has connection means 6, 7 for connection to a valve of a two-wheeled tire.

Die Pumpe umfasst weiterhin ein Manometer 8, das sich von der Zylinder-Kolben-Einheit 1 nach oben erstreckt. Das Manometer 8 ist von Aufnahmemitteln 9 umgeben, an denen auch eine sich über die Zylinder-Kolben-Einheit 1 erstreckende Abdeckung 10 angeordnet ist. Insbesondere sind die Aufnahmemittel 9 und die Abdeckung 10 als einstückiges Teil ausgebildet.The pump further comprises a manometer 8 which extends upwards from the cylinder-piston unit 1. The manometer 8 is surrounded by receiving means 9, on which a cover 10 extending over the cylinder-piston unit 1 is also arranged. In particular, the receiving means 9 and the cover 10 are formed as a one-piece part.

Die Aufnahmemittel 9 sind hohlzylindrisch ausgebildet und weisen einen derartigen Durchmesser auf, dass sie zwischen der Innenwand der Aufnahmemittel 9 und der Außenwand des Manometers 8 einen Ringraum 11 ausbilden. In diesem Ringraum 11 kann der Schlauch 4 in übereinanderliegenden Schlaufen verstaut werden (siehe dazu Fig. 3 und Fig. 6). Insbesondere sind dabei die Schlaufen des Schlauches 4 koaxial zu dem Manometer 8 angeordnet. Für die Verbindung des Pumpenkopfes 5 mit einem Zweitradreifen kann der Schlauch 4 aus dem Ringraum 11 herausgezogen werden.The receiving means 9 are hollow cylindrical and have a diameter such that they form an annular space 11 between the inner wall of the receiving means 9 and the outer wall of the manometer 8. In this annular space 11, the hose 4 can be stowed in loops one above the other (see also Fig. 3 and Fig. 6 ). In particular, the loops of the hose 4 are arranged coaxially with the manometer 8. For the connection of the pump head 5 to a two-wheel tire, the tube 4 can be pulled out of the annular space 11.

Die Pumpe umfasst weiterhin ein erstes Gehäuseteil 12 und ein zweites Gehäuseteil 13, die Teil eines an sich bekannten Tretmechanismus sind (siehe Fig. 2). Das erste Gehäuseteil 12 ist als ein Basisteil ausgebildet, das auf einem Boden aufstehen kann. Das zweite Gehäuseteil 13 ist an der in Fig. 2 linken Seite des ersten Gehäuseteils 12 schwenkbar mit diesem verbunden.The pump further comprises a first housing part 12 and a second housing part 13, which are part of a pedal mechanism known per se (see Fig. 2 ). The first housing part 12 is designed as a base part that can stand on a floor. The second housing part 13 is on the in Fig. 2 left side of the first housing part 12 pivotally connected to this.

Das zweite Gehäuseteil 13 weist eine große mittige Aussparung 14 auf, durch die sich Teile der Zylinder-Kolben-Einheit 1 und der Aufnahmemittel 9 mit dem Manometer 8 hindurch erstrecken können (siehe beispielsweise Fig. 2, Fig. 5 und Fig. 6). Dabei ist die Zylinder-Kolben-Einheit 1 gelenkig mit der in Fig. 2 rechten Seite des ersten Gehäuseteils 12 verbunden und weiterhin gelenkig etwa mittig an dem zweiten Gehäuseteil 13 angebracht.The second housing part 13 has a large central recess 14 through which parts of the cylinder-piston unit 1 and the receiving means 9 with the pressure gauge 8 can extend (see for example Fig. 2 , 5 and 6 ). The cylinder-piston unit 1 is articulated with the in Fig. 2 right side of the first Connected housing part 12 and further articulated attached approximately centrally to the second housing part 13.

Das zweite Gehäuseteil 13 ist aus einer ersten Stellung, in der es einen Winkel von beispielsweise 70° mit dem ersten Gehäuseteil 12 einschließt (siehe Fig. 5 und Fig. 6), in eine zweite Stellung überführbar, in der es zumindest teilweise auf dem ersten Gehäuseteil 12 aufliegt (siehe Fig. 3 und Fig. 4). Durch die Bewegung der beiden Gehäuseteile 12, 13 relativ zueinander wird die Zylinder-Kolben-Einheit 1 betätigt, so dass diese Luft durch den Schlauch 4 in den Zweiradreifen pumpt.The second housing part 13 is from a first position in which it encloses an angle of, for example, 70 ° with the first housing part 12 (see 5 and 6 ), can be transferred to a second position in which it at least partially rests on the first housing part 12 (see 3 and 4 ). The movement of the two housing parts 12, 13 relative to one another actuates the cylinder-piston unit 1, so that this air pumps through the tube 4 into the two-wheeled tire.

In der in Fig. 3 und Fig. 4 ersichtlichen zweiten Stellung des zweiten Gehäuseteils 13 befindet sich die Abdeckung 10 in der Aussparung 14 und verschließt diese weitgehend, so dass sich der Eindruck eines weitgehend geschlossenen Gehäuses ergibt.In the in 3 and 4 Obvious second position of the second housing part 13, the cover 10 is in the recess 14 and largely closes it, so that there is the impression of a largely closed housing.
