Description

SchraubenschlüsselWrench

Die Erfindung betrifft ein Handwerkzeug, insbesondere zu den Schraubenschlüsseln aller Größe und Form.The invention relates to a hand tool, in particular to wrenches of all sizes and shapes.

Das Ziel der Erfindung ist die Vereinfachung der Konstruktion, Bequemlichkeit im Betrieb und die Erweiterung der Funktionalen Möglichkeiten der Schraubenschlüsseln. Dieses Problem wird durch des Patentspruches aufgeführte Merkmal gelöst, daß der Arbeitsteil des Schlüssels, ein Kreis ist, ausgeführt mit Auskragungen, diametral - entgegengesetzt zueinander angeordnet sind und auf Winkel &agr; gedreht, der sich in Grenzen 0 = &agr; < 45° der relativen Längsachse des Schlüssels befindet. Fig. 1 in einer Ansicht des Schlüssels komplett.The aim of the invention is to simplify the design, make it easier to use and to expand the functional capabilities of wrenches. This problem is solved by the feature specified in the patent, that the working part of the wrench is a circle, made with projections, arranged diametrically - opposite to each other and rotated at an angle α, which is within the limits 0 = α < 45° of the relative longitudinal axis of the wrench. Fig. 1 in a view of the wrench in its entirety.

Fig. 3 in a view of the working part of the key in the position of rotation of the key in direction B.

Der Schlüssel besteht (Fig. 1) aus zwei Teilen (1) und (2), die sich um die gemeinsame geometrische Drehachse 0 drehen. Beide Teile des Schlüssels können zusätzlich vorläufig durch ein elastisches Element zusammengezogen werden. Die Innenseite des Arbeitsteils des Schlüssels stellt einen Kreis (oder einen Vielflächner) dar, die sich zwischen den beiden Teilen des Schlüssels (1) und (2) und nach Durchmesser gleichen des beschriebenen Durchmessers der zu drehenden Mutter befindet. Auf diesem Kreis befinden sich zwei Auskragungen C und D, jeweils eine auf jeden Teil des Schlüssels, die durch Oberflächen (3),(4),(5) und (6) (Fig. 2 und Fig. 3) begrenzt sind. Auskragungen C und D sind diametral - entgegengesetzt zueinander angeordnet und auf Winkel &agr; gedreht, der sich in der 0 = &agr; < 45° der relativen Längsachse des Schlüssels befindet.The wrench consists (Fig. 1) of two parts (1) and (2) rotating around the common geometric axis of rotation 0. Both parts of the wrench can be additionally temporarily pulled together by an elastic element. The inner side of the working part of the wrench represents a circle (or a polyhedron) located between the two parts of the wrench (1) and (2) and having a diameter equal to the described diameter of the nut to be rotated. On this circle there are two projections C and D, one on each part of the wrench, which are limited by surfaces (3), (4), (5) and (6) (Fig. 2 and Fig. 3). Projections C and D are arranged diametrically - opposite to each other and rotated at an angle α, which is in the 0 = α < 45° of the relative longitudinal axis of the wrench.

Bei der Umdrehung des Schlüssels in Richtung A (Fig. 1, Fig. 2) stützen sich die Oberflächen (5) und (6), Auskragungen C und B auf Mutter, und stoßen sich von ihr ab, die Komponenten Teile des Schlüssels (1) und (2) werden zur Seite auseinandergelaufen und befreien somit die Mutter von Griff.When turning the wrench in direction A (Fig. 1, Fig. 2), the surfaces (5) and (6), projections C and B rest on the nut and push off from it, the component parts of the wrench (1) and (2) are diverged to the side and thus free the nut from grip.

Bei der Umdrehung des Schlüssels in Richtung B (Fig. 1 und Fig. 3) stützen sich die Oberflächen (3) und (4), Auskragungen C und D auf die Mutter, und stoßen sich von ihr ab, ziehen die Komponenten Teile des Schlüssels zusammen, dabei wird die Mutter eng umschlossen.When the wrench is rotated in direction B (Fig. 1 and Fig. 3), the surfaces (3) and (4), projections C and D rest on the nut and repel each other, pulling the component parts of the wrench together, tightly enclosing the nut.

Der angebotene Schlüssel hat eine vereinfachte Konstruktion, ist bequem im Betrieb und besitzt funktionale Möglichkeiten die im gleichen Maße allen Maulschlüsseln sowie allen Schlüsseln mit Umschaltknarre eigen ist.The offered wrench has a simplified design, is convenient in use and has functional possibilities that are equally inherent in all open-end wrenches and all wrenches with a reversible ratchet.
