Description
Josef Pickel, 852 Erlangen, Koldestraße 16 und Georg ildisch, 852 Erlangen, Franzensbader Straße 3 Niederdruck-Hubzylinder Die Erfindung betrifft einen Niederdruck-Hubzylinder, der wegen seines geringen Gewichtes, seiner kleinen Abmessungen in der Ruhelage und seiner bescheidenen Kosten besonders als Wagenheber beim Auswechseln eines Reifens geeignet ist. Josef Pickel, 852 Erlangen, Koldestrasse 16 and Georg ildisch, 852 Erlangen, Franzensbader Straße 3 low-pressure lifting cylinders The invention relates to a low-pressure lifting cylinder, which because of its low weight, its small Dimensions in the rest position and its modest cost especially as a jack when changing a tire.
Ein Niederdruck-Hubzylinder nach der Erfindung ist gekennzeichnet durch einen zickzackförmig zusammengefalteten und an seinen Enden geschlossenen sowie mit Abdeckschaien versehenen, dünnwandigen und breiten Schlauch mit einer Anschlußstelle für die Zufuhr eines Druckmittels, dessen aneinanderliegenden Oberfachenteile bis auf einen schmalen und ringsum verlaufenden freien Rand miteinander fest verbunden sind. Als Druckmittel wird am einfachsten die überschüssige Druckluft im Reserverad eines Kraftwagens benutzt, die während des Hochhebens des Wagens auf den Gebrauchsdruck zurtickgeht. Die Verbindung dor aneinanderliegenden Schlauchtile erfolgt' am zweckmäßigsten durch Kleben, Niederdruck-Hubzylinde r wobei der ringsumlaufende freie Rand zwischen zwei Umbiegungen etwa eine Breite von 1 cm aufweist, so daß im aufgeblasenen Zustande etwa 6 mm dicke Luftschichten vorhanden sind, die starren Einzelplatten gleichen, welche aufeinandergelegt und miteinander verklebt sind. Dadurch wird dem Hubzylinder die nötige Starrheit gegeben. Die Abdeckschalen bilden im aufeinanderliegenden Zustande eine Schachtel, welche selbst bei Verwendung dünnwandiger Folie für den Schlauch die Gefahr einer Verletzung durch äußere Kräfte mit großer Sicherheit ausschließt.A low pressure lifting cylinder according to the invention is characterized by a zigzag folded and closed at its ends and thin-walled and wide hose with a Connection point for the supply of a pressure medium, its adjacent upper compartment parts firmly connected to each other except for a narrow free edge running all around are. The easiest pressure medium is the excess compressed air in the spare wheel of a motor vehicle, which is applied to the use pressure while the vehicle is being lifted declines. The connection between the adjacent hose parts is most expedient by gluing, Niederdruck-Hubzylinde r where the all-round free edge between two bends has a width of about 1 cm, so that When inflated, there are layers of air about 6 mm thick that are rigid The same individual panels are placed on top of each other and glued together. This gives the lifting cylinder the necessary rigidity. Form the cover shells a box when placed on top of one another, which even when using thin-walled Foil for the hose the risk of injury from external forces with great Security excludes.
