Abstract

The ratchet spanner is used for hexagon nuts and hexagon screws. This spanner matches automatically to given hexagon size without the use of attachments. The ratchet spanner has handle with head with toothed ring (2). These teeth act on six sliding blocks (5) which slide in their guides towards ring centre or away from it when the spanner is rotated. The sliding blocks can be cylindrical pins which slide in round bores. The sliding pins can have grooved surfaces for damaged components.

Steckschlüsselsätze mit Ratschen sind seit langem bekannt. Bei diesen Ratschen wird in der Regel durch eine Innenverzannung der Vierkant angetrieben, der zur Aufnahme von einem der vielen verschieden großen Einsätze dient. Es wird als nachteilig empfunden, daß bei solchen Steckschlüsselsätzen der jeweils passende Einsatz für die entsprechende Schraubengröße ausgewechselt werden muß, und auch deshalb eine Vielzahl von Steckschlüsseleinsätzen vorhanden sein soll.Socket sets with ratchets have long been known. With these Ratcheting is usually driven by internal toothing of the square, which is used to accommodate one of the many different sized missions. It will felt to be a disadvantage that in such socket wrench sets the appropriate one The insert must be changed for the corresponding screw size, and also therefore a large number of socket wrench inserts should be available.

Der Erfindung liegt die Aufgabe zugrunde, eine Vielzahl von verschieden großen Einsätzen einzusparen.The invention is based on the object of a variety of different to save large stakes.

Diese Aufgabe wird erfindungsgemäß dadurch gelößt, daß in einem ratschenähnlichen Kopf ein Zahnring gelagert ist, dessen Außenverzahnung der Ratsche dient. Die Innenseite dieses Zahnringes weist sechs Excenter auf. Bei Drehung des Zahnringes werden sechs Schiebesteine in Bewegung gesetzt, wodurch sich die Schlüsselöffnung je nach Drehrichtung verkleinert oder vergrößert.This object is achieved according to the invention that in a ratchet-like Head a toothed ring is mounted, the external toothing of which is used by the ratchet. The inside this toothed ring has six eccentrics. When the toothed ring turns, six Sliding stones set in motion, which opens the key depending on the direction of rotation reduced or enlarged.

Der Gegenstand der Erfindung wird nachfolgend anhand eines auf der Zeichnung dargestellten Ausführungsbeispiels kurz erläutert. Es zeigen: Fig. 1 den Erfindungsgegenstand in Draufsicht unter Portlassung aer Abdeck- und Führungsscheibe und Pig. 2 Querschnitt des Zahnringes mit Schiebestein.The object of the invention is based on one on the Drawing illustrated embodiment briefly explained. They show: Fig. 1 the Subject matter of the invention in plan view with port leaving the cover and guide disk and Pig. 2 Cross section of the toothed ring with sliding stone.

Die in der Zeichung dargestellte Vorrichtung besitzt einen Griff 1 , er dem Griff einer herkommlichen Ratsche ähnlich ist und ins Gehäuse ilbergeht. Der Zahnring 2 wird mittels Sperrklinke 3, die im Griff 1 untergebracht ist, in Drehbewegung gesetzt, wobei die sechs Excenter 4 an der Innenseite des Zahnringes die in Führungen gleitenden sechs Schiebesteine 5 zur Mitte schieben und die Werkstück zur; Drehen einspannen.The device shown in the drawing has a handle 1 , it is similar to the handle of a conventional ratchet and goes into the housing. The toothed ring 2 is by means of a pawl 3, which is housed in the handle 1, in Rotary movement set, the six eccentrics 4 on the inside of the toothed ring Slide the six sliding stones 5 sliding in guides to the center and remove the workpiece to the; Clamp the turning.
