Description
Die Erfindung betrifft eine Knarre mit einem als Ratsche ausgebildeten, an einem mit einem Handgriff versehenen Griffstiel angelenkten Arbeitskopf, der ein Ansatzstück aufweist, das von einer in der Drehebene der Ratsche liegenden Gelenkachse durchsetzt ist und das an seinen sich gegenüberliegenden, zur Drehebene senkrechten Schmalseiten von einer Gelenkgabel des Griffstiels eingefaßt ist, der gegenüber der Drehebene der Ratsche abwinkelbar ist, und mit einer Sicherungseinrichtung für die gewählte Griffabwinkelung, die einen von Hand verstellbaren Riegel aufweist, dem ein senkrecht zur Drehebene der Ratsche stehender Kranz von Verriegelungsöffnungen am Ansatzstück zugeordnet ist, wobei der Riegel aus dem Gabelgrund des Griffstieles herausragt und mittels eines in einem Schlitz des Griffstieles geführten, mit einer Grifffläche versehenen Schiebers gegen die Kraft einer Feder zum Gabelgrund zurückziehbar ist.The invention relates to a ratchet with a ratchet designed as a ratchet, articulated on a handle handle provided with a handle, which has an extension piece which is penetrated by a hinge axis lying in the plane of rotation of the ratchet and which on its opposite narrow sides perpendicular to the plane of rotation of an articulated fork of the handle, which can be angled relative to the plane of rotation of the ratchet, and with a securing device for the selected angle of the handle, which has a hand-adjustable latch to which a ring of locking openings on the extension piece, which is perpendicular to the plane of rotation of the ratchet, is assigned, whereby the latch protrudes from the fork base of the handle stem and can be retracted against the force of a spring to the fork base by means of a slide guided in a slot of the handle stem and provided with a grip surface.
Bei einer derartigen, durch die EP-A-0 027 238 bekannten Knarre ist der von Hand zu betätigende Schieber an der Gelenkgabel angeordnet, weshalb dort die Einstellung und Arretierung einer bestimmten Griffabwinkelung praktisch nur unter Einsatz beider Hände vorgenommen werden kann, was aber vielfach, insbesondere bei in Kfz-Werkstätten anfallenden Arbeiten, lästig ist. Es ist zwar auch eine Einhandbedienung bei an die zu lösende Schraube angesetzter Knarre denkbar, indem man die Griffhand vom Handgriff längs des Griffstieles zum Arbeitskopf vorschiebt und nach Betätigung des Schiebers und Abwinklung des Griffstieles wieder zum Handgriff zurückschiebt. Ein solches Arbeiten ist aber sehr umständlich und nur möglich, wenn ausreichend Platz zur Aufnahme der Hand im Bereich der zu lösenden Schraube vorliegt. Darüber hinaus hat es sich bei derartigen abwinkelbaren Knarren, die für einen Einsatz bei schwer zugänglichen Stellen bestimmt sind, als sehr kritisch erwiesen, daß beim Anziehen der Knarre der Schieber bei Auftreffen auf vorstehende Ecken ungewollt zurückgeschoben und damit die Verriegelung der Griffabwinklung aufgehoben werden kann. Dies kann in Anbetracht der oft erheblichen, zum Lösen einer Schraube aufzuwendenden Kräfte zu ernsthaften Verletzungen führen.In such a ratchet known from EP-A-0 027 238, the manually operated slide is arranged on the articulated fork, which is why the setting and locking of a certain grip angle can practically only be carried out using both hands, which, however, often especially for those occurring in car workshops Working is annoying. It is also conceivable for one-hand operation with the ratchet attached to the screw to be loosened, by pushing the handle hand from the handle along the handle handle to the working head and pushing it back to the handle after actuating the slide and angling the handle handle. Such work is very cumbersome and only possible if there is enough space to hold the hand in the area of the screw to be loosened. In addition, it has proven to be very critical in the case of such angled ratchets, which are intended for use in hard-to-reach places, that when the ratchet is tightened, the slider is pushed back unintentionally when it encounters protruding corners and the locking of the angled handle can thus be released. In view of the often considerable forces that are required to loosen a screw, this can lead to serious injuries.
Durch die GB-A-550 038 ist ein Maulschlüssel bekannt, der aus einem schwenkbar an einem Griffstiel gelagerten Arbeitskopf besteht und bei dem der Griffstiel innerhalb der Drehebene des Maulschlüssels gegenüber dem Maul abgewinkelt werden kann. Der Arbeitskopf weist einen rückwärtigen Zahnkranz auf, in welchen ein in einem axialen Kanal des Griffstieles gelagertes Sperrglied eingreift, welches mittels eines den Griffstiel umschließenden Schieberinges entriegelbar ist. Der Schiebering liegt dort im Abstand vor dem Handgriff, so daß auch dort bei einer Einhandbedienung die Griffhand vom Handgriff vorgeschoben oder zumindest sehr weit gespreizt werden muß, was bei der dortigen Abwinklung innerhalb der Maulschlüsseldrehebene noch durchführbar sein dürfte, nicht aber bei der gattungsgemäßen Knarre, bei der der Griffstiel senkrecht zur Drehebene der Knarre abzuwinkeln ist und dementsprechend angehoben bzw. abgesenkt werden muß.GB-A-550 038 discloses an open-ended wrench which consists of a work head pivotably mounted on a handle and in which the handle can be angled relative to the jaw within the rotating plane of the open-end wrench. The working head has a rear toothed ring, in which a locking member which is mounted in an axial channel of the handle shaft engages and which can be unlocked by means of a sliding ring which surrounds the handle shaft. The sliding ring is located at a distance in front of the handle, so that even with a one-hand operation, the handle hand must be pushed forward from the handle or at least very widely spread, which is the case with the angling there within the Open-end wrench level should still be feasible, but not with the generic ratchet, in which the handle is angled perpendicular to the level of rotation of the ratchet and must be raised or lowered accordingly.
Durch die EP-A-0 027 238, Fig. 9, und durch die EP-A-0070 725 sind ferner Schraubwerkzeuge mit abwinkelbarem Griffstiel bekannt, bei welchen die zu betätigenden Entriegelungsmittel im Bereich des Handgriffes angeordnet sind, jedoch derart ausgebildet sind, daß eine Griffabwinklung praktisch nur unter Zuhilfenahme beider Hände durchgeführt werden kann. Bei diesen Ausführungsformen ist es im Falle beengter Verhältnisse kaum möglich, die jeweils geeignete Griffstielabwinklung bei bereits an die zu lösende Schraube angesetztem Werkzeug vorzunehmen, sondern bei solchen Werkzeugen muß im allgemeinen die Griffabwinklung vorab eingestellt werden und dann nach Ansetzen an die zu lösende Schraube kann erst ausprobiert werden, ob eine geeignete Abwinklung gewählt worden ist. Bei der Ausführungsform nach Fig. 9 der EP-A-0 027 238, bei der die Entriegelung mittels eines am hinteren Ende des Handgriffes angeordneten Stößels nach Art eines Kugelschreibers vorgenommen wird, ist eine Einhandbedienung zwar auch denkbar, jedoch muß hierzu die Griffhand jeweils am Handgriff umgesetzt werden, was wiederum umständlich ist.From EP-A-0 027 238, Fig. 9, and from EP-A-0070 725 screwing tools with an angled handle are also known, in which the unlocking means to be operated are arranged in the region of the handle, but are designed such that an angled grip can practically only be carried out with the help of both hands. In these embodiments, it is scarcely possible in the case of cramped conditions to carry out the appropriate handle shaft angling with a tool already attached to the screw to be loosened, but in the case of such tools, the handle angling must generally be set in advance and then only after attachment to the screw to be loosened be tested whether a suitable angle has been chosen. In the embodiment according to FIG. 9 of EP-A-0 027 238, in which the unlocking is carried out by means of a plunger arranged at the rear end of the handle in the manner of a ballpoint pen, one-hand operation is also conceivable, however, the handle hand must be on Handle can be implemented, which in turn is cumbersome.
Durch die DE-A-3 518 661 und die US-A-4 711 145 sind ferner abwinkelbare Knarren bekannt, bei denen durch Drehen des zuvor zu entkuppelnden Handgriffes die Verriegelung bzw. die Entriegelung des Griffstieles am Arbeitskopf vorgenommen wird. Diese Knarren sind nur unter Einsatz beider Hände abwinkelbar. Darüber hinaus verlangen diese Ausführungesformen eine verhältnismäßig aufwendige Kinematik zur Übersetzung der Drehbewegung des Handgriffes in eine lineare Vorschubbewegung der Verriegelungsnase.From DE-A-3 518 661 and US-A-4 711 145 bendable ratchets are also known, in which the locking or unlocking of the handle on the working head is carried out by turning the handle to be uncoupled. These creak are just bendable using both hands. In addition, these embodiments require a relatively complex kinematics for translating the rotary movement of the handle into a linear feed movement of the locking lug.
Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Knarre dahingehend zu verbessern, daß die Griffabwinklung und die Arretierung der abgewinkelten Stellung in bequemer Weise mit nur einer Hand durchgeführt werden können.The invention has for its object to improve the generic ratchet in such a way that the handle bend and the locking of the angled position can be carried out in a convenient manner with only one hand.
Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, daß der Griffstiel mit einem zentralen, bis zum Bereich des Handgriffes reichenden Führungskanal versehen ist und der Riegel eine im Führungskanal verschiebbare, den Schieber tragende Stange aufweist und daß der Handgriff an seinem dem Arbeitskopf zugewandten, einen Daumenwulst aufweisenden Ende mit einem Ausschnitt versehen ist, welcher den Schieber in seiner Grundstellung etwa konturenbündig mit dem Daumenwulst aufnimmt.To achieve this object, it is provided according to the invention that the handle is provided with a central guide channel extending to the region of the handle and the latch has a rod which can be moved in the guide channel and carries the slide, and that the handle has a thumb bead on its working head facing the working head End is provided with a cutout which receives the slider in its basic position approximately flush with the thumb bead.
Durch diese Maßnahme wird eine Reihe von Vorteilen erreicht. Zum einen kann der im Bereich des Daumenwulstes liegende Schieber mit dem Daumen derselben Hand, mit der der Handgriff gefaßt wird, ohne Umsetzen dieser Hand betätigt werden, wobei der Riegel zwecks Entriegelung aus den Verriegelungsöffnungen zurückgezogen, bzw. für ein Wiedereinrasten unter Wirkung der Feder freigegeben wird. Durch die nunmehr konturenbündige Aufnahme des Schiebers innerhalb der Kontur des Daumenwulstes ist ferner erreicht, daß der Schieber nicht durch Auftreffen auf eine vorspringende Ecke oder dgl. ungewollt in eine Entriegelungsstellung überführt wird. Die Knarre besteht nur aus wenigen, einfach montierbaren Teilen, so daß sie preiswert herstellbar ist.This measure achieves a number of advantages. On the one hand, the slider lying in the area of the thumb bead can be actuated with the thumb of the same hand with which the handle is grasped, without moving this hand, the bolt being withdrawn from the locking openings for unlocking, or released for re-engagement under the action of the spring becomes. The fact that the slider is now flush with the contour within the contour of the thumb bead also ensures that the slider does not collide with a projecting one Corner or the like is unintentionally transferred to an unlocking position. The ratchet consists of only a few, easily assembled parts, so that it can be manufactured inexpensively.
Nach weiteren Merkmalen der Erfindung kann die Stange an ihrem aus dem Gabelgrund herausragenden Ende eine Riegelnase in Form einer Schraubendreherklinge aufweisen und können die Verriegelungsöffnungen als Schlitze ausgebildet sein. Zur leichteren Einrastung kann dabei vorgesehen werden, daß die Riegelnase oder die Schlitze randseitige Abfasungen oder schwach divergierende Seitenflächen aufweisen.According to further features of the invention, the rod can have a locking lug in the form of a screwdriver blade at its end protruding from the fork base and the locking openings can be designed as slots. For easier engagement, it can be provided that the locking lug or the slots have bevels on the edge or weakly diverging side surfaces.
