Abstract

A screw driver with any kind of tip or a screw driver bit to be joined with its shaft (20) to a suitable handle is provided with a multitude of minuscule projections (23) distributed across all contact surfaces (22). When the tip is inserted into the matching slot of a screw head the projections (23) act as an anti-slip surface, keeping the tip safely in position during the tightening or loosening process.

Description

Die Erfindung bezieht sich auf ein Drehwerkzeug mit einer Anti-Rutscheinrichtung nach einem der Ansprüche 1 bis 3. Unter Drehwerkzeugen werden hier insbesondere Schraubendreher und Werkzeugbits verstanden, mit denen sich Schrauben, Muttern und dergleichen drehen, anziehen oder lösen lassen.The invention relates to a Rotary tool with an anti-slip device according to one of claims 1 to 3. In particular, screwdrivers are among turning tools and tool bits understood with which screws, nuts and Turn, tighten or loosen the like.

Die Zeichnung zeigt in den 1 bis 3 verschiedene Ausführungsbeispiele für erfindungsgemäße Drehwerkzeuge.The drawing shows in the 1 to 3 different embodiments for turning tools according to the invention.

Das erste Ausführungsbeispiel in 1 zeigt ein Drehwerkzeug in Form eines Werkzeugbits mit einem Schaft 20 zur Aufnahme in einem Halter. Der Schaft 22 weist an einem Ende einen Werkzeugabschnitt mit mehreren, radial angeordneten Rippen 21 auf, die jeweils eine oder mehrere Anlageflächen 22 ausbilden. Über letztere wird ein zu drehendes Element, wie beispielsweise eine Mutter, ein Bolzen, eine Schraube oder dergleichen angetrieben. Bei dem in 1 dargestellten Ausführungsbeispiel sind an dem Schaft 20 vier Rippen 21 vorgesehen, um ein Kreuzschlitz-Werkzeugbit zu bilden ("Phillips Head"). Bei dem in 2 dargestellten Ausführungsbeispiel ist lediglich eine einzige Rippe 21 vorgesehen. In 3 weist die Rippe 21 in etwa die Form eines Vierkants auf und besitzt so vier Anlageflächen 22.The first embodiment in 1 shows a turning tool in the form of a tool bit with a shaft 20 for holding in a holder. The shaft 22 has at one end a tool section with a plurality of radially arranged ribs 21 on, each one or more investment areas 22 form. An element to be rotated, such as a nut, a bolt, a screw or the like, is driven via the latter. At the in 1 illustrated embodiment are on the shaft 20 four ribs 21 provided to form a Phillips tool bit ("Phillips Head"). At the in 2 The illustrated embodiment is only a single rib 21 intended. In 3 shows the rib 21 roughly the shape of a square and thus has four contact surfaces 22 ,

Der Schaft 20 ist an einer oder mehreren der Anlageflächen 22 der Rippen 21 mit einer Anzahl von Partikeln oder nach außen vorstehenden Vorsprüngen 23 versehen, und/oder mit einer Anzahl von Vertiefungen 24 zwischen den Partikeln bzw. Vorsprüngen 23, um eine geriffelte oder gerippte Oberflächenstruktur zu bilden. Die Partikel bzw. Vorsprünge 23 und die Vertiefungen 24 des Schafts 20 sind an demselben durch Giesverfahren, Schmieden, Hämmern, Prägen, Pressen, etc. hergestellt.The shaft 20 is on one or more of the contact surfaces 22 the ribs 21 with a number of particles or protrusions protruding outwards 23 provided, and / or with a number of wells 24 between the particles or projections 23 to form a corrugated or ribbed surface structure. The particles or protrusions 23 and the wells 24 of the shaft 20 are made on the same by casting, forging, hammering, stamping, pressing, etc.

Im Betrieb können die Partikel oder Vorsprünge 23 flächig in Anlage mit den anzutreibenden Elementen in Eingriff gebracht werden, um zu verhindern, daß das Drehwerkzeug relativ zu dem angetriebenen Element gleitet, wodurch verhindert wird, daß das Drehwerkzeug beim Drehen des zu drehenden Elements von diesem abrutscht.In operation, the particles or protrusions 23 be brought into abutting engagement with the elements to be driven in order to prevent the rotary tool from sliding relative to the driven element, thereby preventing the rotary tool from sliding off the element to be rotated when the element to be rotated is rotated.
