Abstract

A cooling arrangement in which the winding cylinder (2) has air- circulation vents (3) of chosen shape and size. The winding cylinder can selectively have spirally encircling directional fins, the latter being hollow and open on the inner side so that they can have air-circulation vents of selected size and shape on all sides.

Description

Um der Gefahr zu begegnen, daß sich das auf der Trommel befindende Kabel unter Belastung zu stark erhitzt, wird hier eine Anordnung vorgeschlagen, die eine Luftkühlung bewirkt. Bisher muß das Kabel abgerollt werden, um eine Überhitzung zu verhindern, oder aber ein eingebauter Überhitzungsschutz schaltet bei Überhitzung den Strom aus. Das ist lästig und beeinträchtigt die Effektivität der Arbeit.Around to face the danger that the cable on the drum heats up too much under load, an arrangement is proposed here which effects air cooling. So far, the cable unrolled to prevent overheating to prevent, or a built-in overheating protection switches in case of overheating the electricity out. It is annoying and impaired the effectiveness work.

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, eine zusätzliche Kühlung des auf der Trommel befindlichen Kabels zu bewirken. Dies geschieht, indem Luft von innen nach aussen am Kabel entlang streichen kann. Hier wird durch besondere Anordnungen eine große Fläche dieses Kabels auf seiner gesamten Länge durch Luft zusätzlich gekühlt.The The invention specified in claim 1 is based on the problem additional cooling of the to cause cable located on the drum. This happens, by allowing air to sweep along the inside of the cable. Due to special arrangements, a large area of this cable is on his entire length through air additionally cooled.

Der im Schutzanspruch 2 angegebenen Erfindung liegt das Problem zugrunde, das Kabel gleichmäßiger zu kühlen und dazu die Kühlleistung zu erhöhen.The In invention protection claim 2 is based on the problem the cable more evenly cool and the cooling capacity too increase.

Der im Schutzanspruch 3 angegebenen Erfindung liegt das Problem zugrunde, die Kühlleistung zu maximieren.The In the protection claim 3 invention is based on the problem the cooling capacity too maximize.

Die Erfindung nach 1 kann bevorzugt bei beweglichen, elektrisch betriebenen Arbeitsgeräten mit großer und/oder länger anhaltender Leistungsaufnahme und langer Leitungszuführung bei wie Rasenmähern und anderen Arbeitsgeräten, besonders im Dauereinsatz, Anwendung finden. Der Schutzanspruch 2 einhaltet eine Variante, die größere Sicherheit bietet. Der Schutzanspruch 3 beinhaltet eine Variante, die größere Leistung bietet.The The invention according to FIG. 1 can preferably be used with movable, electrically operated ones implements with great and / or longer persistent power consumption and long cable feed like lawnmowers and other tools, especially in continuous use. The right to protection 2 includes a variant that offers greater security. The Protection claim 3 includes a variant, the greater performance offers.
