Abstract

The insert has a special shape e.g. wing shape, for engagement of a screw in a form-fit manner. The screw has a corresponding shape. The insert is adjustable. The insert is provided with or without a centering pin. The wing shape of the insert provides robust material at weakest points between the screw and the insert. The insert is designed in a conical shape.

Description

Bei den heutigen Schraubereinsätzen und Schrauben tritt das Problem auf, dass beim Ein- und ausschrauben die Schrauben und der Einsatz ausgerieben werden und sich die Schrauben dann nicht mehr verarbeiten lassen.at today's screwdriver bits and screws the problem occurs that when screwing in and out the screws and the insert are to be rubbed out and the screws then no longer process.

Durch die besondere Form des Schraubereinsatzes wird erreicht, dass an den schwachen Punkten der Schraube und des Einsatzes mehr Material vorhanden ist und diese dadurch stabiler sind (I).The special shape of the screwdriver insert ensures that more material is present at the weak points of the screw and the insert, making them more stable ( I ).

Die kraftschlüssige Form des Einsatzes wirkt grossflächig auf die Schraube. Durch die Form des Einsatzes und der Schraube kann die Schraube aufgesetzt werden ohne herunterzufallen und ermöglicht somit ein Arbeiten mit einer Hand oder arbeiten über Kopf (II)The frictional shape of the insert acts on the screw over a large area. Due to the shape of the insert and the screw, the screw can be put on without falling down and thus allows working with one hand or working overhead ( II )

Durch die flügelförmige Form des Einsatzes und der Schraube wird ein abrutschen und ausreiben vermieden.By the wing-shaped form The insert and the screw will prevent it from slipping and rubbing out.

Selbst eingerostete Schrauben lassen sich durch das exakte Eingreifen des Einsatzes wieder lösen.Even rusted screws can be replaced by the exact intervention of the Use again.

Der Schraubereinsatz kann gerade oder konisch gestaltet sein. Er kann mit oder ohne Zentrierstift ausgestattet sein. Der Schraubereinsatz und die Schraube können 2, 3, oder 4-flügelig gestaltet werden (je nach den besten Ergebnissen einer praktische Prüfung) (III, IV, V).The screwdriver bit can be straight or tapered. It can be equipped with or without centering pin. The screwdriver bit and the screw can be made 2, 3 or 4 blades (depending on the best results of a practical test) ( III . IV . V ).

Bei herkömmlichen Schraubereinsätzen muss je nach Schraubengrösse eine anderer Einsatz gewählt werden. Durch eine Verstelleinrichtung kann der neue Schraubereinsatz für mehrere Grössen verwendet werden.at usual Screwdriver bits must depending on screw size another use chosen become. By an adjustment of the new screwdriver can for many sizes be used.

Der verstellbare Schraubereinsatz erspart das Wechseln der Einsätze bei Verwendung von anderen Schraubengrössen.Of the adjustable screwdriver saves you from having to change the inserts Use of other screw sizes.
