Description

Klemmschlüssel. Die Erfindung betrifft eine neue Bauart eines Klemmschlüssels mit beweglichen Backen, die sich bei der einen Bewegung des Handgriffes voneinander trennen, bei der anderen Bewegungsrichtung den Gegenstand um so fester klemmen, je stärker der Druck am Handgriff ausgeübt wird.Clamp wrench. The invention relates to a new type of clamping wrench with movable jaws that move apart when the handle is moved separate, with the other direction of movement clamp the object all the more tightly, the more pressure is exerted on the handle.

Zu diesem Zweck schließt an den Griff ein Kniehebelsystem an, das aus zwei als Klemmbacken ausgebildeten Hebelteilen besteht, die miteinander durch drei Bolzen verbunden, gegeneinander eine gewisse Bewegung zulassen, innerhalb welcher sie frei spielen können, so daß sich die Maulweite des Schlüssels dem Werkstück selbsttätig anpaßt.For this purpose, a toggle system is attached to the handle, the consists of two lever parts designed as clamping jaws, which are connected to one another three bolts connected to each other allow a certain movement within which they can play freely, so that the width of the wrench fits the workpiece adapts automatically.

Gegenüber bereits bekannten Klemmschlüsseln dieses Systems zeigt die Erfindung eine gedrängte Bauart, dabei große Verstellbarkeit_ der Backen und weit größere Handlichkeit, was insbesondere dadurch erreicht wird, daß die drei Drehbolzen zum Zusammenhalten der zwei Klemmbacken bei mittlerer Öffnung derselben in einer Linie mit dem Handgriff liegen und der obere Klemmbacken gabelförmig den Griff und den unteren Backen umschließt.Compared to the already known clamping wrenches of this system, the Invention of a compact design, with great adjustability of the jaws and wide greater handiness, which is achieved in particular by the fact that the three pivot pins to hold the two clamping jaws together with a central opening of the same in one Line with the handle and the upper jaw fork-shaped the handle and encloses the lower jaw.

Der Erfindungsgegenstand ist in der Zeichnung in Fig. x in offener, in Fig. 2 in Schließstellung dargestellt, während Fig. 3 die Rückseite des Werkzeuges zeigt. Die am Handgriff a angelenkten oberen und unteren Backenteile b und c besitzen verschiedene in der Mittellinie des Griffes liegende Drehpunkte d und e und sind untereinander in bekannter Weise durch einen in einem Schlitz geführten Bolzen f verbunden. Der Zapfen d ist geteilt, und der obere Backen b umschließt den unteren sowie das gabelförmige Ende des Griffes und ist mit diesen abgeglichen. Alle drei Drehpdnkte gelangen beim Übergang von der offenen in die geschlossene Stellung der Backen vorübergehend in eine gerade Linie. Statt des Griffes kann auch der untere Bakkenteil gegabelt sein. a Durch die gedrängte Bauart, die weite Verstellbarkeit der Backen und die glatten Außenflächen ist das Werkzeug als Universalschlüssel oder auch als Rohrzange verwendbar und insbesondere für Montage vorzüglich geeignet.The subject of the invention is shown in the drawing in FIG. X in the open position and in FIG. 2 in the closed position, while FIG. 3 shows the rear side of the tool. The upper and lower jaw parts b and c hinged to the handle a have different pivot points d and e located in the center line of the handle and are connected to one another in a known manner by a bolt f guided in a slot. The pin d is divided, and the upper jaw b encloses the lower and the fork-shaped end of the handle and is aligned with these. All three pivot points are temporarily in a straight line during the transition from the open to the closed position of the jaws. Instead of the handle, the lower jaw part can also be forked. a Due to the compact design, the wide adjustability of the jaws and the smooth outer surfaces, the tool can be used as a universal wrench or as a pipe wrench and is particularly suitable for assembly.
