Description

Schraubenschlüssel. Es sind Schraubenschlüssel bekannt, bei denen der Kopf dem Handgriff des Schlüssels gegenüber mit Hilfe eines Rädergetriebes derart drehbar ist, daß der Kopf zu dem Handgriff verschiedene Winkelstellungen bekommen kann, so daß man imstande ist, die betreffende Mutterschraube zu umfassen und herauszudrehen, ohne Hinsicht auf die Winkelstellung, die sie einnimmt.Wrench. There are known wrenches in which the head of the handle of the key opposite with the help of a gear train in such a way is rotatable that the head get different angular positions to the handle can, so that one is able to grasp and unscrew the nut screw in question, regardless of the angular position it occupies.

Die Erfindung betrifft eine besondere Ausführungsform eines solchen Schlüssels, die auf der Zeichnung in Vorderansicht und in Seitenansicht, diese teilweise im Schnitt, dargestellt ist.The invention relates to a particular embodiment of such Key shown on the drawing in front view and in side view, these partially in section, is shown.

Der Schraubenkopf a, der sowohl für viereckige als auch für sechseckige oder anders geformte Muttern oder Schraubenköpfe ausgebildet sein kann, hat an beiden Seiten die bekannte zirkelförmige Nut b und c, in welche Vorsprünge d und e zweier Beschlaghälften j und k eingreifen, so daß der Kopf a in der bekannten Art verschwenkt werden kann. Der Kopf hat einen Zahnkranz g, der in den Hohlraum f einragt, den die zwei Beschlaghälften j und k oben zwischen sich lassen; dieser Zahnkranz g steht im Eingriff mit einem von demselben Hohlraum umschlossenen Zahnrad h.The screw head a, which can be designed for both square and hexagonal or differently shaped nuts or screw heads, has on both sides the well-known circular groove b and c, in which projections d and e of two fitting halves j and k engage so that the Head a can be pivoted in the known manner. The head has a ring gear g which protrudes into the cavity f, which the two fitting halves j and k leave between them at the top; this ring gear g meshes with a gear h enclosed by the same cavity.

Die Beschlaghälften j und k umschließen einen Schaft 1, um den sie zusammen gespannt werden können mittels der dargestellten Spannschrauben oder Bolzen m und n. In dem Schaft l .drehbar ist eine Welle o, die oben das Zahnrad h trägt und am anderen Ende unter dem Schaft einen eckigen Zapfen p bildet, auf welchem ein Handgriff q befestigt ist, z. B. mittels einer Mutter r. Wenn der Handgriff q und damit die Welle o gedreht wird, dreht sich auch das Zahnrad h, das durch den Zahnkranz g auf den Kopf a einwirkt und ihn verschwenkt.The fitting halves j and k enclose a shaft 1 around which they can be clamped together by means of the clamping screws or bolts m and n shown Shank forms an angular pin p on which a handle q is attached, e.g. B. by means of a mother r. When the handle q and thus the shaft o is rotated, the gear wheel h also rotates, which acts on the head a through the ring gear g and pivots it.

Dem Schaft L kann eine andere Form gegeben werden, und wenn die Welle o gebogen oder gegliedert ist, kann er auch mehr oder weniger krumm sein. Bei Verwendung eines Zahnradeingriffes oder eines Kardangelenkes kann er aus Stücken zusammengesetzt sein, die stumpfe oder spitze Winkel miteinander bilden.The shaft L can be given a different shape, and if the shaft o is curved or articulated, it can also be more or less crooked. Using a gear mesh or a cardan joint, it can be assembled from pieces that form obtuse or acute angles with one another.
