Description

Feststellvorrichtung für das Zirkelgelenk. Die Erfindung betrifft eine Vorrichtung zum Feststellen des Zirkelgelenks, insbesondere von Werkstattzirkeln.Locking device for the circular joint. The invention relates to a device for fixing the compass joint, in particular workshop circles.

Es sind bereits Zirkel bekannt geworden, bei denen durch Verstellen einer Schraube am Zirkelgriff die Zirkelschenkel infolge Keilwirkung festgespannt werden.There are already compasses known in which by adjusting a screw on the compass handle clamped the compass legs due to the wedge effect will.

Die .Erfindung besteht demgegenüber darin, daß die zwischen der Zirkelgabel liegenden Köpfe der Zirkelschenkel konisch angefräst sind und eine gemeinsame Keilnot bilden, in. welche ein konischer Rundkeil gedrückt wird, der die beiden Zirkelschenkel an die Innenwände der Zirkelgabel preßt.The .Erfindung consists in the fact that between the compass fork lying heads of the compass legs are milled conically and have a common wedge form, in. which a conical wedge is pressed, which the two compass legs presses against the inner walls of the compass fork.

Der Gegenstand der Erfindung ist auf der Zeichnung an einem Ausführungsbeispiel näher erläutert. -Fig. z zeigt den Zirkel in Vorderansicht. Fig. 2 und 3 erläutern in senkrechten Schnitten die Feststellvorrichtung der Schenkel.The object of the invention is based on the drawing of an exemplary embodiment explained in more detail. -Fig. z shows the compass in front view. Figs. 2 and 3 explain the locking device of the legs in vertical sections.

Der Zirkel besteht aus den beiden Schenkeln a und b, welche um einen Bolzen c verdrehbar sind und von denen der Schenkel a unmittelbar mit einer Spitze d versehen ist, während die andere Spitze e sich an einem besonderen Arm f befindet, welcher drehbar am Schenkel b angeordnet ist und mittels einer Feineinstellung g eingestellt werden kann.The compass consists of the two legs a and b, which can be rotated about a bolt c and of which the leg a is directly provided with a point d, while the other point e is on a special arm f, which is rotatable on the leg b is arranged and can be adjusted by means of a fine adjustment g.

Zur Feststellung der Schenkel a und b sind nun ihre aufeinander drehenden Köpfe h am Umfang durch eine konische Anfräsung mit einer gemeinsamen keilförmigen Nut i- versehen, in die ein entsprechend konischer Rundkeil k eingreift, welcher in der Zirkelgabel radial beweglich gelagert ist. Durch die Zirkelgabelt geht eine als Griff ausgebildeteSchraubem, die sich gegen den Rundkeil k legt und diesen schon bei leichter Verdrehung satt-in die Nut i eindrückt, wodurch eine sichere Feststellung der Schenkel a und b erreicht wird.To determine the legs a and b , their rotating heads h are now provided on the circumference by a conical milling with a common wedge-shaped groove i- in which a correspondingly conical round wedge k engages, which is mounted radially movable in the circular fork. A screw, designed as a handle, goes through the compass fork and rests against the round wedge k and presses it snugly into the groove i even with a slight twist, thereby securing the legs a and b in place.
