Die vorliegende Erfindung betrifft einen Ratschenschlüssel, insbesondere einen Schraubenschlüssel, mit einem Steuermechanismus.The present invention relates to a ratchet wrench, in particular a wrench, with a control mechanism.

Die Erfindung sowie vorteilhafte Ausgestaltungen der Erfindung sind in den Ansprüchen definiert.The invention and advantageous embodiments of the invention are defined in the claims.

Anhand der Zeichnungen wird ein Ausfuhrungsbeispiel der Erfindung näher erläutert. Es zeigen:An embodiment of the invention is explained in more detail using the drawings. They show:

Fig. 1 eine Explosionsdarstellung eines Ratschenschlüssels; Fig. 2 eine perspektivische Ansicht des Ratschenschlüssels; Fig. 3 eine schematische Draufsicht auf den Kopf des Ratschenschlüssels zum Veranschaulichen seiner Funktionsweise.Fig. 1 is an exploded view of a ratchet wrench; Fig. 2 is a perspective view of the ratchet wrench; Fig. 3 is a schematic plan view of the head of the ratchet wrench to illustrate its operation.

Der in den Figuren dargestellte Ratschenschlüssel (Schraubenschlüssel) besitzt an einem Ende eines Handgriffes 30 einen Kopf 301, der eine kreisförmige Aufnahme 31, eine mit der Aufnahme 31 verbundene Ausnehmung 311 sowie ein Loch 32 aufweist, das zu der Aufnahme 31 konzentrisch ist und etwas kleiner als die Aufnahme 31 ausgebildet ist. Eine Ringnut 33 und eine Bohrung 34 sind in dem Kopf 301 gebildet. In der Aufnahme 31 ist ein Zahnring 35 drehbar gelagert, der mit einer Schlüsselöffnung 36 zum Erfassen eines Befestigungselementes (Schraube oder Mutter) oder einer Werkzeugverlängerung sowie einen Haltering 37 zum Erfassen des Befestigungselementes aufweist. Ein Sperrglied 40 ist in der Ausnehmung 311 angeordnet und ist mit einem oder mehreren Zähnen 48 versehen, die mit dem Zahnring 35 in Eingriff bringbar sind. Ein Block 50 ist mit einem Vorsprung 51 versehen, der in die Bohrung 34 greift. Eine Feder 60 liegt mit einem Ende an dem Block 50 und mit dem anderen Ende an dem Sperrglied 40 an, um das Sperrglied 40 in Eingriff mit dem Zahnring 35 zu drücken. Eine Abdeckung 38 liegt an dem Zahnring 35, dem Sperrglied 40 und dem Block 50 an, um diese Teile in ihrer Lage zu halten. Ein Klemmring 39 sitzt in der Ringnut 33, um die Abdeckung 38The ratchet wrench (screw wrench) shown in the figures has a head 301 at one end of a handle 30, which has a circular receptacle 31, a recess 311 connected to the receptacle 31 and a hole 32 that is concentric with the receptacle 31 and is slightly smaller than the receptacle 31. An annular groove 33 and a bore 34 are formed in the head 301. A toothed ring 35 is rotatably mounted in the receptacle 31, which has a key opening 36 for gripping a fastening element (screw or nut) or a tool extension and a retaining ring 37 for gripping the fastening element. A locking member 40 is arranged in the recess 311 and is provided with one or more teeth 48 that can be brought into engagement with the toothed ring 35. A block 50 is provided with a projection 51 which engages in the bore 34. A spring 60 bears with one end against the block 50 and with the other end against the locking member 40 to urge the locking member 40 into engagement with the toothed ring 35. A cover 38 bears against the toothed ring 35, the locking member 40 and the block 50 to hold these parts in position. A clamping ring 39 sits in the annular groove 33 to hold the cover 38

am Kopf 301 festzulegen. Der Ratschenschlüssel hat somit einen äußerst einfachen, konstruktiven Aufbau.on the head 301. The ratchet wrench therefore has an extremely simple structural design.
