Description

Kantenschraubzwinge. Von den bekannten Kantenzwingen mit an zweiarmigen Hebeln sitzenden zwei seitlichen Klemmbacken, deren Hebel um Zapfen eines Verbindung§stückes schwingen und durch ein als Mutter für die.die dritte Backe tragende Schraubspindel ausgebildetes Keilstück bewegt werden, unterscheidet sich der Erfindungsgegenstand dadurch, daß das bekannte als Spindelmutter ausgebildete Keilstück in dem die Schwinghebel tragenden Verbindungsstücke frei verschiebbar geführt ist.Edge screw clamp. From the well-known edge clamps with two-armed ones Lever seated two lateral clamping jaws, the lever around the pin of a connecting piece swing and through a screw spindle that supports the third jaw as a nut formed wedge are moved, the subject of the invention differs in that the known wedge formed as a spindle nut in which the rocker arm bearing connecting pieces is guided freely displaceable.

Bei dem Bekannten ist das auf die Hebel wirkende, als Spindelmutter ausgebildete Keilstück mittels Nuten bzw. Federn an den Hebeln geführt und verursachte bei zu starkem Spindeldruck eine Verdrehung dieser Hebel, wodurch die Zwinge in ihrer Schraubkraft behindert, wenn nicht gänzlich unbrauchbar wurde.In the case of the acquaintance, it is the spindle nut that acts on the lever trained wedge guided by means of grooves or springs on the levers and caused If the spindle pressure is too high, this lever will twist, causing the clamp to turn into hindered their screwing power, if not completely useless.

Dieser Mangel ist durch die neue Bauart behoben. Das zur Mutter für -die Schraubspindel ausgebildete Keilstück a hat eine lange flache Form erhalten und findet in dem Verbindungsstück b frei verschiebbar Führung. Letzteres besteht aus zwei gepreßten Teilen mit einer genügend großen Bohrung für die Spindel. Die Teile sind mit den Nieten c verbunden, während die Nietend als Drehzapfen für die Schwinghebel dienen. Die beiden Lappen e des Verbindungsstückes umfassen dabei die Hebelenden und dienen zugleich zur Aufnahme der Zapfen f, welche nach außen unsichtbar in einer Bohrung dei Hebel festsitzen und in den Nuten g des Verbindungsstückes b bewegt werden. Damit ist die Bewegung der Hebel auf die Spannweite begrenzt.This deficiency has been remedied by the new design. That to mother for -the screw spindle-shaped wedge piece a has been given a long, flat shape and is guided in the connecting piece b so that it can slide freely. The latter exists from two pressed parts with a sufficiently large bore for the spindle. the Parts are connected to the rivets c, while the rivet end acts as a pivot for the Serve rocker arm. The two tabs e of the connector include the Lever ends and also serve to accommodate the pin f, which is invisible to the outside sit tight in a hole of the lever and in the grooves g of the connecting piece b be moved. This limits the movement of the levers to the span.

PATENTANSPRÜCHE: i. Kantenschraubzwinge mit an zweiarmigen Hebeln sitzenden zwei seitlichen Klemmbacken, deren Schwinghebel um Zapfen eines Verbindungsstückes schwingen und durch ein als Mutter für die' die dritte Backe tragende Sehr aubspindel ausgebildetes Keilstück bewegt werden, dadurch gekennzeichnet, daß das Keilstück frei verschiebbar in dem Verbindungsstück geführt ist. z. Ausführungsform der Zwinge nach Anspruch r, dadurch gekennzeichnet, daß das Verbindungsstück (b) aus zwei gepreßten Teilen besteht, welche mit den Nieten (c) verbunden, die beiden Hebel, das Keilstück und die Schraubspindel umfassen, während die beiden oberen Lappen (e) des Verbindungsstückes zur Aufnahme von nach außen unsichtbaren Zapfen (f) dienen, welche in einer Bohrung der Hebel festsitzen und in den Nuten (g) des Verbindungsstückes bewegt werden. PATENT CLAIMS: i. Edge screw clamp with two lateral clamping jaws sitting on two-armed levers, the rocking levers of which swing around the pin of a connecting piece and are moved by a wedge piece designed as a nut for the very aubspindel carrying the third jaw, characterized in that the wedge piece is guided freely in the connecting piece. z. Embodiment of the clamp according to claim r, characterized in that the connecting piece (b) consists of two pressed parts, which are connected by the rivets (c) and encompass the two levers, the wedge piece and the screw spindle, while the two upper tabs (e) of the connecting piece are used to receive outwardly invisible pins (f), which are stuck in a hole in the lever and are moved in the grooves (g) of the connecting piece.
