Description

Ratschenartig arbeitender Mutterschlüssel. Die Priorität der Anmeldung in der Schweiz vom 3. März 1925 ist in Anspruch genommen. Unter den bekannten ratschenartig arbeitenden Mutterschlüsseln sind solche, die mit einem federnd gelagerten Schieber außer der sch%"ingbaren Backe und dem schwingbaren Griff versehen sind, und wieder andere, deren eine Backe schieberartig verstellbar und außerdem eine Sperrung vorgesehen ist. Diese Schlüssel sind vielteilig und üben keine Klemmwirkung auf die Mutter aus. Im Gegensatz dazu gibt es auch einen wenigteiligen Ratschenschlüssel, dessen Backen aber zu schnell die Parallelität verlieren und daher leicht abrutschen.Ratchet-like wrench. The priority of the registration in Switzerland of March 3, 1925 has been claimed. Among the known ratchet-like working wrenches are those which are provided with a spring-mounted slide apart from the slidable jaw and the swingable handle, and still others whose one jaw is adjustable like a slider and also has a lock. These keys are multi-part and In contrast to this, there is also a ratchet wrench made up of several parts, but the jaws of which lose their parallelism too quickly and therefore easily slip off.

Der Schlüssel der Erfindung. arbeitet wie eine Zange, kann für verschiedene Maulweiten verwendet werden und wird billig in der Herstellung. Das wird erfindungsgemäß dadurch erreicht, daß die einarrrmige Hauptbacke mit dem zweiarmigen Schlüsselgriff und die zweiarmige Gegenbacke reit der Hauptbacke gelenkig verbunderi sind, so daß in der Spannstellung der untere Hebelarm der Gegenbacke sich an den oberen Hebelarm des Griffes anlegt und in der Ratschstellung der obere Hebelarm des Griffes sich mittels einer Feder auf die Hauptbacke stützt: Die Zeichnung stellt den neuen. Schlüssel dar, und zwar zeigen ihn: Abb. i in der Spannstellung, Seitenansicht, Abb. 2 in der Ratschstellung, Seitenansicht, und Abb. 3 in der Vorderansicht, wobei in allen drei Ansichten der Schlüsselgriff abgebrochen gezeichnet ist.The key to the invention. works like pliers, can for different Mouth widths are used and is cheap to manufacture. That is according to the invention achieved in that the one-armed main jaw with the two-armed key handle and the two-armed counter jaw rides the main jaw are articulated so that in the clamping position, the lower lever arm of the counter jaw is attached to the upper lever arm of the handle and in the ratchet position the upper lever arm of the handle itself by means of a spring on the main jaw: The drawing represents the new one. key show it: Fig. i in the clamping position, side view, Fig. 2 in the ratchet position, side view, and Fig. 3 in the front view, in all three views of the key handle is drawn broken off.

Die einarmige Hauptbacke A ist bei E mit dem zweiarmigen Schlüsselgriff C, G und die z@veiarmige Gegenbacke B bei D, mit der Hauptbacke A gelenkig verbunden. Dabei drückt der Griff C, G beim Punkte H auf die Gegenbacke B sowie eine im Hohlraum 'der Backe A liegende Feder F auf das äußerste Ende des Armes G des Schlüsselgriffes C, G und sucht den Schlüssel immer zu schließen.The one-armed main jaw A is articulated at E with the two-armed key handle C, G and the two-armed counter-jaw B at D, with the main jaw A. The handle C, G presses at point H on the opposing jaw B and a spring F lying in the cavity 'of the jaw A on the outermost end of the arm G of the key handle C, G and always tries to close the key.

Wird nun der Schlüsselgriff C nach dem Pfeil J (Abb. i) bewegt, so wird das Schlüsselmaul um die anzuziehende Mutter, geschlossen, indem auf die Gegenbacke B bei H ein Drück ausgeübt wird und die Hauptbacke A sich auf das Widerlager beize Drehpunkt E stützt.If the key handle C is now moved according to the arrow J (Fig. I), the key opening around the nut to be tightened is closed by exerting pressure on the counter jaw B at H and the main jaw A rests on the counter bearing at pivot point E. .

Bewegt man den Schlüsselgriff C nach dem Pfeil K (Abb. z), so wird die Feder F durch den Arm G zusammengedrückt; die Gegenbacke B wird vom Druck bei H frei, sie kann sich freu bewegen, und die Ratschbewegung über die Mutterkanten kann stattfinden. Sobald diese überfairen sind, schließt aber die Feder F sofort das Maul wieder.If you move the key handle C according to the arrow K (Fig. Z), then the spring F compressed by the arm G; the opposing jaw B is subjected to pressure H free, it can move freely, and the ratchet movement over the nut edges can take place. As soon as these are over-fair, however, the spring F closes immediately the mouth again.

Die Maulkanten sind bei L etwas abgenommen, um .ein leichtes Aufsetzen a#af die Mutter zu ernlöglichen. Die Backe B und der Griffarre G bewegen sich in einer Ausnehmung der Hauptbacke A, und es liegen daher die gleitenden Flächen vor Schmutz geschützt.The mouth edges are slightly removed at L to make it easy to put on a # af to pacify the mother. The jaw B and handle G move in a recess of the main jaw A, and there are therefore the sliding surfaces Dirt protected.
