Abstract

The air pump is driven off a battery with an electric motor for the compressor. There is an adaptor for use on car tyres, bicycle tyres, inflatable dinghies and paddling pools, etc. The compressor is inside a plastic housing forming the "barrel" of the pump whereas the battery and motor are in the "butt". The motor has two drive pinions on its shaft, engaging with two parallel spur gears mounted on bearings in the outer wall of the housing. The crankshaft is provided between the spur gears to drive the compressor piston. The compressor cylinder is spaced away from the housing by several cooling ribs. ADVANTAGE - Simple construction, adaptable for different uses, no mains power needed.

Description

Das Anliegen besteht darin, mit Hilfe der Erfindung, eine mit AKKU betriebene Luftpumpe gleichzeitig als Verdichter wirkend, die Luft so zu komprimieren, daß sie in die Schläuche von Fahr rädern, Motorrädern, Autos, Schlauchbooten, Schwimmbassins und anderer Behältnisse, deren Funktion erst nach Luftauffül lung gewährleistet ist, mühelos eingeblasen werden kann. Ein Kabelanschluß entfällt, schon dadurch gewinnt die Erfindung eine große Bedeutung.The concern is, with the help of the invention, one with Battery operated air pump acting as a compressor, compress the air so that it enters the hoses of Fahr bicycles, motorcycles, cars, inflatables, swimming pools and other containers, the function of which only after filling up with air is guaranteed, can be blown in easily. A cable connection is omitted, the invention alone wins of great importance.

Sie ist so einfach konstruiert, daß sie schnell und richtig auf jedes Ventil aufgesetzt werden kann. Durch die variable Gestal tung der Drehzahl, durch das Aufsetzen von Nippeln für unter schiedliche Drücke, wird die Verwendung vielseitig und das Auf pumpen niederer und höherer Drücke möglich.It is constructed so simply that it opens quickly and correctly any valve can be attached. Thanks to the variable shape speed, by fitting nipples for under different pressures, the use is versatile and the up pumping lower and higher pressures possible.

Da die Luftpumpenpistole eine einfache, bequem zu handhabende Form hat, im Auto und weiterhin überall mühelos mitgenommen werden kann. Dort wo es keinen Kabelanschluß gibt, können auch die schon bestehenden Kleinstkompressoren, die an Autobatte rien angeschlossen werden können, nicht zum Einsatz kommen. So wird diese Luftpumpenpistole an Badestränden und anderen Orten, wo man auch nicht mit dem Auto hinfahren kann zum Auf füllen der Luft besonders wertvoll sein, denn ein Aufpumpen großer Behältnisse bedeutet eigentlich auch viel Anstrengung, bedeutet Kraft, an Stelle von notwendiger Ruhe.Because the air pump gun is a simple, convenient to use Shape has taken with you in the car and continues effortlessly everywhere can be. Where there is no cable connection, you can the already existing mini compressors, the car battery rien can not be used. This is how this air pump gun is used on swimming beaches and others Places where you can't go by car to Auf filling the air can be particularly valuable because of an inflation large containers actually means a lot of effort, means strength instead of necessary rest.

Aber nicht nur im Sommer ist die Erfindung wertvoll, sondern eigentlich immer und zu jeder Jahreszeit.But the invention is valuable not only in summer, but actually always and in every season.

Besonders geeignet könnte die Erfindung sein, für Kraftfahr zeugfahrer, die bei schlechtem Wetter, wie Regen-Schnee-Kälte, Luft in ihre Reifen nachpumpen müssen und mitten im Straßen verkehr stehen, oder sie müssen das Reserverad einwechseln, daß ja bekanntlich nicht immer den notwendigen Betriebsdruck hat. Ein schnelles Einpumpen, ist ja auch eine schnelle Be seitigung der Situation, die auch nicht immer ohne Gefahr ist. Aber erst dann, wenn man in eine solche Lage geraten ist und sich nun schnell helfen kann, ist man sich selbst dankbar, zum Kauf entschlossen zu haben. Zum Aufladen der AKKUs haben sie, ihre Freunde oder Bekannte, ein dafür geeignetes Ladegerät, das natürlich auch zum Kauf angeboten wird.The invention could be particularly suitable for motor vehicles witness drivers who are in bad weather, such as rain-snow-cold, Pump air into their tires and in the middle of the road traffic or you have to change the spare wheel, that, as is well known, not always the necessary operating pressure Has. A quick pumping is also a quick loading side of the situation, which is also not always without danger. But only when you have got into such a situation and can help yourself quickly, you are grateful to yourself, to have decided to buy. Have to charge the batteries you, your friends or acquaintances, a suitable charger, which of course is also available for purchase.

Claims

1. Air pump gun, characterized in that a battery is used to operate it and air compression can be carried out electromechanically African way. For hoses of bicycles, motorcycles, cars, inflatable boats, swimming pools and other containers that can only be made functional by compressed air supply.

2. Air pump gun, according to claim 1, characterized in that the entire electro-mechanical drive, including the compressor, is housed in a plastic housing ( 1 ) (see images B, C, D).

3. Air pump gun according to claim 1 u. 2, characterized in that the plastic sleeve ( 1 ) is designed so that it can accommodate the battery ( 2 ), the motor ( 3 ), the compressor ( 4 ), the vibration wheel ( 5 ) and other small mechanical parts, efficiently .

4. Air pump gun according to claim 1, 2, 3, characterized in that via two gears ( 11 ) connected to the motor, convert the electrical energy into mechanical power and via two flywheels ( 5 ), the internal spacing of which is so great that the flywheel ( 10 ), the neces sary freedom of movement, while the flywheels ( 5 ), on the outer walls of the plastic housing ( 1 ), are mounted in plain bearings.

5. Air pump gun according to claim 1-4, characterized in that by the rotational movement of the flywheels ( 5 ), designed as a solid disc or spoke wheel, the mechanical force on the flywheel ( 5 ), the flywheel rod steering ( 9 ), the compressor ( 4th ), with its pressure valve ( 12 ), sets in motion and thus effects the air compression.

6. Air pump gun according to claims 1-5, characterized in that for effective cooling a further system of air channels is created (see Figure AA) that cooling fins ( 8 ), with the existing cavities ( 6 ) that arise in the housing , Air is directed over the outer walls of the compressor ( 4 ), whereby additionally on the flywheel ( 5 ), on the outward-facing surfaces of the wind vane ( 7 ) (see figure E), for additional air movement for cooling, the path via the cooling fins ( 8 ), takes place, while the air will escape through the through the end plate ( 13 ), as shown in picture AA. The print path is forward and backward.

7. Air pump gun according to claims 1-6, characterized in that the rotational speed of the motor ( 3 ), gradually adjustable and on the output nipple ( 14 ), different reducing nipples can be placed.

All bearings are in plain bearings. The material is plastic, for the compressor steel or Hard plastic.
