Description

Es sind verschiedene verstellbare Schraubenschlüssel mit einer festen und einer parallel beweglichen Backe bekannt, bei denen die bewegliche Backe eine Zahnstange aufweist, in die zum Feststellen der beweglichen Backe eine Klinke eingreift. Alle diese Schlüsse) lassen sich jedoch sehr schwer mit nur einer Hand verstellen, und zudem ist die Verriegelung nicht sicher. Der erfindungsgemäße Schlüssel läßt sich dagegen sehr einfach und mit großer Sicherheit handhaben.There are several adjustable wrenches with a fixed one and a parallel movable jaw known, in which the movable jaw a Has rack in which a pawl engages to lock the movable jaw. However, all these keys are very difficult to adjust with just one hand, and the locking is not secure. The key according to the invention leaves on the other hand, can be handled very easily and with great security.

Die bewegliche Backe a ist unterhalb ihrer Gleitführung mit Zähnen versehen, deren Teilung gleich der Differenz zweier aufeinanderfolgender Schlüsselweiten ist. In diese Zähne rasten die Klinkenzähne eines Klinkenhebels c ein, welcher sich um einen Zapfen b dreht. Der Klinkenhebel ist als vorderer Schenkel des Schlüsselgriffes ausgebildet und wird durch eine Schraubenfeder f dauernd in die Stellung gedrückt, in der seine Klinkenzähne in die Verzahnung der beweglichen Backe eingreifen. Andererseits drückt die gleiche Feder gegen einen Arm eines zweiarmigen Stützhebels e, dessen anderer Arm dadurch an einem Daumendrücker d anliegt und mit der Stirn seines Endes den Klinkenhebel in der eingerasteten Stellung verriegelt.The movable jaw a is below its sliding guide with teeth provided, the division of which is equal to the difference between two successive wrench sizes is. The ratchet teeth of a ratchet lever c engage in these teeth, which is rotates around a pin b. The latch lever is the front leg of the key handle and is constantly pressed into the position by a helical spring f in which his ratchet teeth engage in the toothing of the movable jaw. on the other hand presses the same spring against an arm of a two-armed support lever e, whose the other arm rests against a thumb press d and with the forehead of its end locks the ratchet lever in the engaged position.

Um die Maulweite des Schlüssels zu verstellen, drückt man auf den Daumendrücker, wodurch der Stützhebel so verschwenkt wird, daß die Abstützung des Klinkenhebels aufgehoben ist, worauf durch Handdruck auf diesen ein Ausrasten der Klinke aus der Gegenverzahnung und darauf ein freies Verschieben der beweglichen Backe möglich ist. Wird der Klinkenhebel wieder losgelassen, so gehen dieser und der Stützhebel unter der Federwirkung selbsttätig in ihre Sperrstellungen zurück.To adjust the opening width of the key, press the Thumb press, whereby the support lever is pivoted so that the support of the The ratchet lever is canceled, whereupon the hand pressure on this disengages Pawl out of the counter-toothing and on it a free shift of the movable one Cheek is possible. If the ratchet lever is released again, this and go the support lever automatically returns to its locking position under the action of the spring.

PATENTANSPRUCH: Schraubenschlüssel mit einer festen und einer parallel beweglichen Backe, welch letztere mit einer Zahnstange versehen und durch eine Klinke feststellbar ist, dadurch gekennzeichnet, daß der Klinkenhebel (c) zum Ein- und Ausrasten der Klinke als vorderer Schenkel des Schlüsselgriffes ausgebildet ist und sich in eingerasteter Stellung gegen das Ende eines Stützhebels (e) abstützt, der seinerseits durch Betätigung eines Daumendrückers (d) gegen die Wirkung einer Feder (f) so verschwenkt werden kann, daß die Abstützung des Klinkenhebels aufgehoben ist, worauf durch Handdruck auf diesen ein Ausrasten der Klinke und darauf ein freies Verschieben der beweglichen Backe möglich ist, so lange, bis der Klinkenhebel wieder losgelassen wird, worauf dieser und der Stützhebel unter der Federwirkung in ihre Sperrstellungen zurückgehen. PATENT CLAIM: Wrench with a fixed jaw and a parallel movable jaw, the latter being provided with a toothed rack and lockable by a pawl, characterized in that the pawl lever (c) for engaging and disengaging the pawl is designed as the front leg of the key handle and is in the locked position against the end of a support lever (e), which in turn can be pivoted against the action of a spring (f) by actuating a thumb lever (d ) so that the support of the ratchet lever is canceled, whereupon it disengages by hand pressure on it the pawl and then a free shifting of the movable jaw is possible until the pawl lever is released again, whereupon this and the support lever return to their locking positions under the action of the spring.
