Abstract

This screwdriver was designed in order to be able to turn difficult-to-reach screws in tubes or guides. Due to this screwdriver, the dismantling of heavy parts, in particular window and door elements, for adjustment has become virtually superfluous.

Description

Beschreibungdescription

Schraubendreher Die Erfindung betrifft einen Schraubendreher, dessen Klinge so ausgeführt ist, daß er für Innensechskantschrauben, Innensechskant-Madenschrauben, Schlitzmadenschrauben oder Kreuzschlitzmadenschrauben geeignet ist, insbesondere zum Erreichen schwerzugänglicher Schrauben und Madenschrauben.Screwdriver The invention relates to a screwdriver, the The blade is designed so that it can be used for Allen screws, Allen screws, Slotted grub screws or Phillips grub screws is suitable, in particular to reach hard-to-reach screws and grub screws.

Die Schrauben, die in Führung, Hülsen oder Rohren eingebracht sind, sind meist schwer zu erreichen.The screws that are inserted in the guide, sleeves or tubes, are usually difficult to reach.

Die käuflichen Schraubendreher sind für in Rohren und/ oder Führungen eingesetzte Schrauben ungeeignet, wenn jene Führungen etc. an Rahmen oder Wänden befestigt sind, weil der Griff an diesen Rahmen oder Wänden scheuert", und somit keinen Platz für die drehende Hand läßt.The commercially available screwdrivers are for in pipes and / or guides The screws used are unsuitable if those guides etc. are on frames or walls are attached because the handle rubs against these frames or walls ", and thus leaves no room for the turning hand.

Es bleibt nur der Einsatz eines normal gebogenen Sechskantschlüssels, der aber nicht umdreht werden kann, sondern wegen der hindernden Wand immer neu eingesetzt werden muß, oder es ist meistens notwendig, das Teil komplett auszubauen und nachzuregulieren. Dieser Vorgang muß gelegentlich mehrfach wiederholt werden, da im ausgebauten Zustand jegliche Kontrolle fehlt.All that remains is to use a normally bent hexagon key, which, however, cannot be turned around, but always new because of the obstructing wall must be used, or it is usually necessary to completely remove the part and readjust. This process has to be repeated several times from time to time. since there is no control in the expanded state.

Aufgabe und Lösung Der Erfindung liegt die Aufgabe zugrunde, diese schwerzugänglichen Schrauben leichter zu verdrehen ohne Ausbau der'diese Führungen enthaltenen Teile; rund die Teilevielzahl der Werkzeuge auf einer Bau- oder Arbeitsstelle zu reduzieren.Task and solution The invention is based on the task of this Difficult-to-access screws can be turned more easily without removing these guides included parts; around the number of parts of the tools on a construction site or work site to reduce.

Die Aufgabe wird erfindungsgemãßdadurch gelöst, daß ein Kardangelenk in der Klinge vorhanden ist und daß das untere Klingenteil direkt im Kardangelenk eingebaut ist und mindestens 30 mm lang ist.The object is achieved according to the invention in that a cardan joint is present in the blade and that the lower blade part is directly in the universal joint installed and at least 30 mm long.

Vorteil Durch das Kardangelenk wird ein Abbiegen des Heftes von der Schraubendrehachse von mindestens 100 gewährleistet, wodurch die drehende Hand Freiraum gewinnt.Advantage The universal joint prevents the booklet from turning away from the Guaranteed screw rotation axis of at least 100, which gives the turning hand free space wins.

Es ergibt sich-außerdem eine Zeitersparnis von ca.90 %.There is also a time saving of about 90%.

Die Arbeit ist jetzt in jedem Falle alleine ausführbar, d.h. es ergibt sich eine Personalersparnis , weil die zu verstellenden Teile nicht mehr ausgebaut werden müssen.The work can now be carried out alone in any case, i.e. it results personnel savings because the parts to be adjusted are no longer removed Need to become.

Durch den Nichtausbau erhöht sich zudem die Arbeitssicherheit, da nichts mehr fallen kann und schweres Heben wird vermieden.The non-expansion also increases occupational safety, as nothing can fall and heavy lifting is avoided.

B-eigefugte Zeichnung zeigt ein mögliches Ausführungsbeispiel dieser Art von Schraubendrehern.B-eigefugte drawing shows a possible embodiment of this Kind of screwdriver.

Wobei Teil Nr. 1 das Heft oder der Griff 2 das obere Teilstuck der Klinge 3 das Kardangelenk 4 das untere Teilstück der Klinge ist.Where part no. 1 is the booklet or the handle 2 is the upper part of the Blade 3 the universal joint 4 is the lower part of the blade.
