Abstract
Um einen Ratschenschlüssel für einen Wagenheber mit einem als Griff auslaufenden, aus Schalen (1, 2) zusammengesetzten Gehäuse, das ein mit einer zentralen Aufnahme versehenes Zahnrad (5) und eine Sperrklinke (8) mit einer Klinkenführung (10) trägt, wobei die Sperrklinke (8) über eine Feder an das Zahnrad (5) angedrückt wird und das Zahnrad (5) vorzugsweise wenigstens an einer Seite mit einem Bund (4) ausgebildet ist, der eine Bohrung (3) der zugehörigen Schale (1, 2) durchgreift, zu vereinfachen und die Bauteile so zu gestalten, dass sie keinem hohen Verschleiß unterworfen sind bzw. dass sie bei gleicher Belastung dünner bzw. leichter ausgebildet werden können, liegen wenigstens zwei Seitenflächen (12, 13) der Klinkenführung (10) formschlüssig an der Innenwand des Gehäuses an. To a ratchet wrench for a jack with a housing, which ends as a handle and is composed of shells (1, 2), which carries a gearwheel (5) provided with a central receptacle and a pawl (8) with a pawl guide (10), the pawl (8) is pressed against the gearwheel (5) by means of a spring and the gearwheel (5) is preferably formed on at least one side with a collar (4) which passes through a bore (3) in the associated shell (1, 2), To simplify and design the components so that they are not subject to high wear or that they can be made thinner or lighter under the same load, there are at least two side surfaces (12, 13) of the pawl guide (10) in a form-fitting manner on the inner wall of the Housing.
