BeschreibungDescription
Das Gebrauchsmuster betrifft einen Ratschenschlüssel.The utility model relates to a ratchet wrench.
Die Erfindung sowie vorteilhafte Ausgestaltungen sind in den Ansprüchen gekennzeichnet.The invention and advantageous embodiments are characterized in the claims.
Die Erfindung wird nachfolgend unter Bezugnahme auf die Zeichnung in einem Ausfuhrungsbeispiel näher erläutert. In der Zeichnung zeigt:The invention is explained in more detail below with reference to an embodiment example and the drawing. In the drawing:
Fig. 1 eine perspektivische Ansicht eines Ratschenschlüssels, Fig. 2 eine Explosionsdarstellung des Ratschenschlüssels undFig. 1 is a perspective view of a ratchet wrench, Fig. 2 is an exploded view of the ratchet wrench and
Fig. 3 eine Schnittdarstellung des Ratschenschlüssels. Der in der Zeichnung dargestellte Ratschenschlüssel hat einen Kopf 20 an einem Ende eines Griffes 10 mit einer Kammer 21 zur Aufnahme eines Blockes 30. Der Block 30 hat eine Öffnung 31 und zwei Kanäle 32, die mit der Öffnung in Verbindung stehen. Weiter hat der Block 30 mindestens eine Bohrung 35. In der Öffnung 31 des Blockes 30 liegt drehbar ein Zahnrad 40, das an gegenüberliegenden Seiten zwei Schäfte 41, 42 hat. Ein Klinkenpaar 33 mit entsprechenden Federn 34 liegt in den Kanälen 32 des Blockes 30. In die in diesem Ausführungsbeispiel vorgesehenen zwei Bohrungen 35 sind je zwei Zapfen 51 eingesetzt, die sich an zwei Scheiben 50 befinden. Jede Scheibe 50 hat eine Öffnung 501, durch die der Schaft 41 bzw. 42 läuft. Die Scheiben 50 halten das Zahnrad 40 im Block 30. Jede Scheibe 50 hat einen Schlitz 52 in Verbindung mit der Öffnung 501 sowie drei Vertiefungen 53. In diese Vertiefungen 53 greifen federgespannte Vorsprünge 63 zweier Steuerringe 60 ein, die ebenfalls eine Öffnung 67 zum Durchführen der Schäfte 42 bzw. 41 haben. Über die federgespannten Vorsprünge 63 und die Vertiefungen 53 werden die Steuerringe 60 gegenüber den Scheiben 50 und den Kopf 20 positioniert. Ein Steuerring 60 hat einen Arm 610, der andere einen Vorsprung 61 mit einer Öffnung 62 für den Arm 610, in der dieser beispielsweise im Preßsitz sitzt. Dadurch sind die Steuerringe 60 drehbar am Block 30 und dem Kopf 20 befestigt und können nur miteinander gedreht werden.Fig. 3 is a sectional view of the ratchet wrench. The ratchet wrench shown in the drawing has a head 20 at one end of a handle 10 with a chamber 21 for receiving a block 30. The block 30 has an opening 31 and two channels 32 which are connected to the opening. The block 30 also has at least one bore 35. A gear 40 which has two shafts 41, 42 on opposite sides is rotatably located in the opening 31 of the block 30. A pair of pawls 33 with corresponding springs 34 is located in the channels 32 of the block 30. Two pins 51 which are located on two disks 50 are inserted into each of the two bores 35 provided in this embodiment. Each disk 50 has an opening 501 through which the shaft 41 or 42 runs. The disks 50 hold the gear 40 in the block 30. Each disk 50 has a slot 52 in connection with the opening 501 and three recesses 53. Spring-loaded projections 63 of two control rings 60, which also have an opening 67 for the shafts 42 and 41 to pass through, engage in these recesses 53. The control rings 60 are positioned relative to the disks 50 and the head 20 via the spring-loaded projections 63 and the recesses 53. One control ring 60 has an arm 610, the other a projection 61 with an opening 62 for the arm 610, in which the arm sits, for example, in a press fit. The control rings 60 are thus rotatably attached to the block 30 and the head 20 and can only be rotated together.
Der Vorsprung 61 des einen Steuerrings 60 greift zwischen die Klinken 33, und löst eine von beiden vom Zahnrad 40, so daß die Antriebsrichtung der Schäfte 41, 42 eingestellt werden kann. Die federgespannten Vorsprünge 63 der Steuerringe 60 greifen in eine der Vertiefungen 53, so daß die Steuerringe 60 gegenüber den Scheiben 50 und dem Kopf 20 positioniert werden. Mittels der Schäfte 41, 42 können entsprechende Steckschlüssel angetrieben werden.The projection 61 of one control ring 60 engages between the pawls 33 and releases one of them from the gear 40 so that the drive direction of the shafts 41, 42 can be adjusted. The spring-loaded projections 63 of the control rings 60 engage in one of the recesses 53 so that the control rings 60 are positioned opposite the disks 50 and the head 20. The shafts 41, 42 can be used to drive corresponding socket wrenches.
Alternativ kann auf den Block 30 verzichtet werden, und die Öffnungen 31 sowie die Kanäle 32 können direkt im Kopf 20 gebildet werden.Alternatively, the block 30 can be omitted and the openings 31 and the channels 32 can be formed directly in the head 20.
