Description

Die Erfindung betrifft eine Knarre mit einem als Ratsche ausgebildeten, an einem 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, which is articulated on 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 by an articulated fork of the handle is bordered, which can be angled with respect to the plane of rotation of the ratchet, and with a securing device for the selected grip angle, which has a manually adjustable bolt, to which a ring of locking openings on the extension piece, which is perpendicular to the plane of rotation of the ratchet, is assigned, the bolt from the The fork base of the handle stem protrudes 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 handle and provided with a grip surface.

Bei einer derartigen, durch die DE-PS 29 41 616 bekannten Knarre ist der von Hand zu betätigende Schieber an der Gelenkgabel angeordnet, weshalb dort die Einstellung und Arretierung einer bestimmten Griffabwinkelung nur unter Einsatz beider Hände vorgenommen werden kann, was aber vielfach, insbesondere bei in Kfz-Werkstätten anfallenden Arbeiten, lästig ist.In such a ratchet known from DE-PS 29 41 616, the manually operated slide is arranged on the joint fork, which is why the setting and locking of a certain angle of the handle can only be carried out using both hands, which is often the case, in particular with in car workshops, is annoying.

Durch die Erfindung soll die gattungsgemäße Knarre dahingehend verbessert werden, daß die Griffab­winkelung und die Arretierung der abgewinkelten Stellung mit nur einer Hand durchgeführt werden können.The invention aims to improve the generic ratchet in such a way that the handle bend and the locking of the angled position can be carried out 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 daß der Riegel aus einer im Führungs­kanal verschiebbaren Stange besteht, die mit einem in Daumenreichweite des Handgriffes liegenden Schieber starr verbunden ist. Durch diese Maßnahmen ist nunmehr möglich, mit derselben Hand, mit der der Knarrenhand­griff gefaßt wird, auch den Schieber mit dem Daumen zu betätigen, wobei der Riegel zwecks Entriegelung aus den Verriegelungsöffnungen zurückgezogen, bzw. für ein Wiedereinrasten unter der Wirkung der Feder, freigegeben wird. Der Schieber kann dabei mit Abstand vor dem Handgriff angeordnet sein.To achieve this object, the invention provides that the handle handle is provided with a central guide channel extending to the region of the handle and that the bolt consists of a rod which can be displaced in the guide channel and which is rigidly connected to a slide located within the thumb reach of the handle. These measures now make it possible to operate the slide with your thumb with the same hand with which the ratchet handle is gripped, the bolt being withdrawn from the locking openings for the purpose of unlocking or being released for re-engagement under the action of the spring . The slide can be arranged at a distance from the handle.

Gemäß einer Weiterbildung der Erfindung kann dabei vorgesehen werden, daß die Stange um einen Winkel von etwa 20o bis 90o, vorzugsweise von 30o, drehbar ist und daß ihr Schieber in einem abgewinkelten Griff­stiel-Schlitz geführt ist, der aus einem vorderen axialen Teil und einem hinteren radialen Teil besteht. Hierdurch ist es möglich, den aus der Verriegelungs­öffnung herausgezogenen Riegel in der zurückgezogenen Stellung zu sichern, so daß die Knarre zunächst mit einem frei beweglich angelenkten Griffstiel auf die zu lösende Schraubverbindung aufgesetzt wird, wonach dann der Griffstiel in die gewünschte, den speziellen Ver­hältnissen entsprechende Winkelstellung geschwenkt wird. Anschließend wird mit derselben Betätigungshand der Schieber aus der gesicherten Drehstellung zurück­gedreht und für eine Einrastung in die Verriegelungs­öffnung unter der Wirkung der Feder freigegeben.According to a development of the invention, can be provided in this case that the rod is at an angle of about 20 o to 90 o, preferably 30 o, rotatable and that it is guided in an angled grip handle slot valve, the axial from a front portion and a rear radial part. This makes it possible to secure the bolt pulled out of the locking opening in the retracted position, so that the ratchet is first placed on the screw connection to be loosened with a freely articulated handle, after which the handle is in the desired angular position corresponding to the special conditions pivoted becomes. The slide is then turned back out of the secured rotational position with the same operating hand and released for engagement in the locking opening under the action of the spring.

Zweckmäßigerweise umfaßt der Schieber einen den Griff­stiel umschließenden Ring, der mit einer Daumenmulde versehen ist, die sowohl nach hinten als auch in die Umfangsrichtungen ansteigende Griffflächen aufweist. Durch diese Maßnahmen und insbesondere durch die lange Führung der Stange ist eine sehr leichtgängig zu handhabende Verriegelungseinrichtung geschaffen.The slide expediently comprises a ring which surrounds the handle, which is provided with a thumb recess which has grip surfaces which rise both towards the rear and in the circumferential directions. These measures and in particular the long guidance of the rod create a locking device that is very easy to handle.

Gemäß einer bevorzugten Ausführungsform kann vorge­sehen werden, daß der Schieber in einem Ausschnitt des vorderen Endes des Griffes angeordnet ist, wobei der Handgriff am vorderen Ende mit einem den Ausschnitt aufweisenden Daumenwulst versehen ist und wobei der Schieber ein in der Grundstellung innerhalb des Daumenwulstausschnittes liegendes Griffende aufweist. Das Griffende füllt den Daumenwulstausschnitt etwa konturenbündig aus.According to a preferred embodiment it can be provided that the slide is arranged in a cutout of the front end of the handle, the handle being provided at the front end with a thumb bead having the cutout and the slide having a handle end lying in the basic position within the thumb bead cutout . The end of the handle fills the thumb bulge approximately flush with the contours.

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.

Der Griffstiel 1 ist hierzu an einem Ende als Lagergabel 6 ausgebildet, welche ein mit einer Bohrung für die Gelenkachse 5 versehenes Ansatzstück 7 des Arbeitskopfes 3 einfaßt. Der Griffstiel 1 ist um die Gelenkachse 5 schwenkbar und damit gegenüber der Dreh­ebene der Ratsche abwinkelbar.The ratchet shown in FIGS. 1 to 5 consists of a handle handle 1 with a handle 2, and a working head 3 with a square piece 4 mounted as a ratchet, which are pivoted to one another via an articulated axis 5. For this purpose, the handle 1 is designed at one end as a bearing fork 6, which surrounds an attachment 7 of the working head 3 provided with a bore for the articulated axis 5. The handle 1 is pivotable about the hinge axis 5 and thus angled relative to the rotary plane of the ratchet.

Der Griffstiel 1 ist mit einem zentralen, bis etwa zum Handgriff 2 reichenden Führungskanal 8 für eine Stange 9 versehen, die an ihrem vorderen Ende aus dem Gabel­grund 10 herausragt und an einem verbreiterten Kopf 11 eine nach Art einer Schraubendreherklinge ausgebildete Verriegelungsnase 12 trägt, der ein senkrecht zur Ebene der Ratsche stehender Kranz von Verriegelungs­öffnungen 13 am Ansatzstück 7 zugeordnet ist. An ihrem griffseitigen Ende ist die Stange 9 mittels eines Diametralstiftes 14 mit einem ringförmigen, den Griff­stiel 1 umschließenden Schieber 15 starr verbunden, wobei der Diametralstift 14 jeweils zwei abgewinkelte Schlitze 16, 17 des Griffstieles 1 durchsetzt. Jeder Griffschlitz besteht aus einem vorderen, axialen Teil 17a und einem hinteren, radial gerichteten Schlitzteil 17b. Zwischen dem hinteren Stirnende der Stange 9 und dem Boden 18 des sacklochartigen Führungskanales 8 ist eine Druckfeder 19 eingespannt, die die Stange 9 in Richtung auf einen Eingriff der Verriegelungsnase 12 in eine der Verriegelungsöffnungen 13 belastet, wie in Fig. 3 gezeigt ist.The handle 1 is provided with a central, up to about the handle 2 guide channel 8 for a rod 9, which protrudes at its front end from the fork base 10 and on a widened head 11 carries a locking nose 12 designed in the manner of a screwdriver blade, the one perpendicular to the ratchet plane of the ring of locking openings 13 on the extension 7 is assigned. At its end on the handle side, the rod 9 is rigidly connected by means of a diametrical pin 14 to an annular slide 15 enclosing the handle shaft 1, the diametrical pin 14 penetrating two angled slots 16, 17 of the handle shaft 1. Each grip slot consists of a front, axial part 17a and a rear, radially directed slot part 17b. A compression spring 19 is clamped between the rear end face of the rod 9 and the bottom 18 of the blind hole-like guide channel 8, which loads the rod 9 in the direction of an engagement of the locking lug 12 in one of the locking openings 13, as shown in FIG. 3.

Zur Änderung der Griffabwinkelung wird der Ring bzw. Schieber 15 der mit einer geeigneten Daumenmulde 20 versehen ist, die sowohl nach hinten als auch in Umfangsrichtung ansteigende Grifflächen 21, 22, 23 aufweist, mit dem Daumen der den Griff 2 fassenden Hand gegen die Kraft der Feder 19 zunächst axial zurückgezogen, so daß die Nase 12 aus der Verriege­lungsöffnung heraustritt und eine gewünschte Griff­abwinkelung eingestellt werden kann. Um hierbei nicht ständig den Schieber gegen die Kraft der Feder 19 zurückhalten zu müssen, kann der Schieber 15 um etwa 30o in der zurückgezogenen Stellung verdreht werden, wonach die Verriegelungseinrichtung in die Stellung nach Fig. 5 gelangt, in welcher die Verriegelungsnase 12 aus der Verriegelungsöffnung des Ansatzstückes 7 herausgezogen und diese entriegelte Stellung durch die Anlage des Diametralstiftes 14 an der Wandung des radialen Schlitzteiles 17b gesichert ist.To change the angle of the handle, the ring or slider 15, which is provided with a suitable thumb recess 20, which has gripping surfaces 21, 22, 23 rising both to the rear and in the circumferential direction, with the thumb of the hand holding the handle 2 against the force of The spring 19 is initially withdrawn axially, so that the nose 12 emerges from the locking opening and a desired handle angle can be set. In order not to constantly have to hold back the slide against the force of the spring 19, the slide 15 can about 5 o are rotated in the retracted position, after which the locking device moves into the position according to FIG. 5, in which the locking lug 12 is pulled out of the locking opening of the extension piece 7 and this unlocked position by the contact of the diametral pin 14 on the wall of the radial slot part 17b is secured.
