Description

Verstellbarer Schraubenschlüssel mit keilförmigem Schaft. Gegenstand der vorliegenden Erfindung ist eine besondere Ausführungsform eines Schraubenschlüssels jener bekannten Art, bei der der Schlüsselschaft Keilform hat und die Schiebebacke, dieser Keilform angepaßt, durch eine Schraube festgeklemmt wird: Die Zeichnung zeigt die. Erfindung.Adjustable wrench with a wedge-shaped shaft. object The present invention is a particular embodiment of a wrench of the known type in which the key shaft has a wedge shape and the sliding jaw, adapted to this wedge shape, is clamped by a screw: The drawing shows the. Invention.

Der Erfindungsgegenstand besteht aus dem Schaft A, der in der, oberen Hälfte geschlitzt ist, und einer Backe B mit Druckstück C, welche durch die Schraube E verbunden sind.The subject of the invention consists of the shaft A, which is in the, upper Half is slotted, and a jaw B with pressure piece C, which through the screw E are connected.

Der Schaft A hat Keilform, die Backe B und das Druckstück G zeigen an ihren Führungsflächen die Gegenform dazu. Während bei- den bekannten Schlüsseln mit Keilschaft nur die eine Fläche geneigt zur Mittelachse liegt, sind es hier beide Flächen, so daß sich der Schaft hier beiderseits gleichwinklig nach oben verjüngt. Setzt man die Backe B und das Druckstück C in den Schlitz des Schaftes ein und verbindet beide Teile mit der' Schraube E, so klemmen sich Backe und Druckstück auf den Schaft fest. Diese Klemmung ist wegen der Verteilung des Keilwinkels auf zwei Seiten sicherer als bei einseitigem Keil. Wird der Schlüssel nun gebraucht, so nimmt die Schraube die Zugwirkung des Bakkenteils B auf.. Durch Lösen der Schraube läßt sich ein rasches und genaues Einstellen des Schlüsselmaules auf jede beliebige Spannweite erzielen.The shaft A has a wedge shape, the jaw B and the pressure piece G show the counter-shape on their guide surfaces. While both known keys with a wedge shank only one surface is inclined to the central axis, here both surfaces are so that the shank tapers upwards at the same angle on both sides. If you insert the jaw B and the pressure piece C into the slot of the shaft and connect both parts with the 'screw E, the jaw and pressure piece clamp onto the shaft. This clamping is safer than with a one-sided wedge because of the distribution of the wedge angle on two sides. If the key is now needed, the screw absorbs the pulling action of the jaw part B. By loosening the screw, the wrench mouth can be adjusted quickly and precisely to any span.
