Description

Ratschenschlüssel Ratschenschlüssel mit drehbarem Organ zum Fassen von Muttern oder Werkzeugen, welches durch eine Schraubenfeder mitgenommen wird, sind bereits bekannt. Sie haben jedoch den Nachteil, daß die Schraubenfeder von einer besonderen Büchse umschlossen ist, wodurch der Schlüssel für Schraubenmuttern, die nahe an senkrechten Flächen liegen, nicht verwendbar ist. Der Drahtquerschnitt der Schraubenfedern bei Schlüsseln dieser Art ist rechteckig, wobei die äußere und innere Mantelfläche der Schraubenfeder Zylil-iderflächen sind; durch das erforderliche genaue Abschleifen wird die Marktfähigkeit des Schlüssels heruntergesetzt.Ratchet wrench Ratchet wrench with rotatable organ for grasping of nuts or tools, which are taken along by a helical spring, are already known. However, they have the disadvantage that the coil spring of is enclosed in a special sleeve, whereby the wrench for screw nuts, that are close to vertical surfaces cannot be used. The wire cross section The coil springs on keys of this type are rectangular, with the outer and inner lateral surface of the helical spring are cylinder surfaces; by the required precise grinding will degrade the marketability of the key.

Die Erfindung besteht demgegenüber darin, daß auf dem drehbaren Organ zwei Schraubenfedern aufgewickelt sind, von welchen dig en_e_ links- und die andere rechtsgängig ist, und deren eine Enden nebeneinanderliegend in unmittelbarer fester Verbindung mit dem Arbeitshebel sind, während die anderen Enden in bekannter Weise klemmend an dem drehbaren Organ angreifen, an welchem sich der Arbeitshebel bei der Arbeitsleistung stützt.The invention consists in that on the rotatable member two coil springs are wound, one of which dig en_e_ left and the other is right-handed, and one of its ends lying next to each other in the immediate more solid Connection to the working lever are, while the other ends in a known manner clampingly engage the rotatable member on which the working lever is at the work performance supports.

Der Vorteil dieses Ratschenschlüssels besteht darin, daß er überall Anwendung finden kann, wo ein gewöhnlicher Schrauben- oder Steckschlüssel durch Raummangel eine Drehung nicht zuläßt. Auch ist der Schlüssel nach der Erfindung einfacher herzustellen.The advantage of this ratchet wrench is that it can be used anywhere Can be used where an ordinary wrench or socket wrench through Lack of space does not allow rotation. Also the key is according to the invention easier to manufacture.

Die Zeichnung veranschaulicht den Erfindungsgegenstand in einem Ausführungsbeispiel. Es zeigen Abb. i eine Vorderansicht des Schlüssels, Abb. 2 einen Grundriß der Abb. i, Abb. 3 und q. Anwendungsbeispiele.The drawing illustrates the subject matter of the invention in an exemplary embodiment. Fig. 1 shows a front view of the key, Fig. 2 shows a plan view of Fig. i, fig. 3 and q. Application examples.

Der Ratschenschlüssel nach den Abb. i und 2 besteht aus einem drehbaren Organ 3, um welches zwei Schraubenfedern = und 2 gewickelt sind. Die eine Schraubenfeder ist links- und die andere rechtsgängig. Die mittleren Enden der Schraubenfedern sind mit dem Arbeitshebel q. in fester Verbindung, der mit dem drehbaren Organ 3 in keinerlei fester Verbindung steht. Das drehbare Organ 3 dient entweder unmittelbar zur Fassung der Schraubenmuttern oder zur Aufnahme von Einsatzstücken.The ratchet wrench according to Figs. I and 2 consists of a rotatable one Organ 3, around which two helical springs = and 2 are wound. The one coil spring is left-handed and the other right-handed. The middle ends of the coil springs are with the working lever q. in fixed connection with the rotatable member 3 is not in any fixed connection. The rotatable member 3 is either used directly to mount the screw nuts or to accommodate insert pieces.

Die Abb. 3 und q. zeigen die Anordnung von an sich bekannten Einsatzstücken 5 und 6 zur Aufnahme eines Bohrers oder zur Fassung größerer Schraubenmuttern.Fig. 3 and q. show the arrangement of inserts known per se 5 and 6 to accommodate a drill or to mount larger nuts.

Die Wirkung des Schraubenschlüssels liegt darin, daß beim Anziehen des Schlüssels in der Pfeilrichtung die beiden Federn i und 2 fest um das drehbare Organ gezogen werden und dasselbe mitnehmen, während bei der Rückwärtsbewegung die Federn sich erweitern und um das drehbare Organ schleifen.The effect of the wrench is that when it is tightened of the key in the direction of the arrow the two springs i and 2 firmly around the rotatable Organ are pulled and take the same with you, while in the backward movement the Feathers expand and drag around the rotating organ.
