Description

Gebrauchsmuster-Anmeidung (2783). Herr Alfred Wike. B r e m e n. Reergtr. 391. Schlitzschraube. ========== Bei der Benutzung von Schlitzschrauben, insbes. von Madenschrauben, wie sie vorzugsweise von Elektroinstallateuren verwendet werden, ergibt sich der Übelstand, daß sie wegen ihrer Kleinheit sehr schwer gehalten und in das Muttergewinde eingeführt werden können. Werden sie auf die Schneide des zu ihrer Bedienung dienenden Schraubenziehers gesetzt, dann fallen sie herunter, sobald der Schraubenzieher geneigt wird. Dieser Übelstand soll durch die Neuerung in besonders einfacher Weise behoben werden. Die Neuerung besteht darin, daß die Schlitzschraube eine sich an den Schlitzgrund anschließende Längsbohrung und der zu ihrer Bedienung bestimmte Schraubenzieher einen sich an seine Schneide anschließenden, in die Längsbohrung der Schlitzschraube passenden Zapfen erhält* Die einzuschraubende Schlitzschraube wird mit ihrer Längsbohrung so auf den Zapfen des Schraubenziehers aufgesteckt, daß dessen Schneide in den Schlitz der Schraube greift. In dieser Stellung wird sie auch beim Neigen des Schraubenziehers gehalten, so daß sie bequem an das Muttergewinde angesetzt und in dieses eingeschraubt werden kann. Utility model avoidance (2783). Mr. Alfred Wike. B reme n. Reergtr. 391 Slotted screw. ========== When using slotted screws, especially grub screws, as they are preferably used by electrical installers, there is the disadvantage that they can be held very difficult because of their small size and inserted into the nut thread. If they are placed on the cutting edge of the screwdriver used to operate them, then they fall down as soon as the screwdriver is tilted. This drawback is intended to be remedied in a particularly simple manner by the innovation. The innovation is that the slotted screw has a longitudinal hole adjoining the bottom of the slot and the screwdriver intended for its operation has a pin that adjoins its cutting edge and fits into the longitudinal hole of the slotted screw Screwdriver attached so that its cutting edge engages in the slot of the screw. It is held in this position even when the screwdriver is tilted, so that it can be conveniently attached to the nut thread and screwed into it.

Auf der Zeichnung ist ein Ausführungsbeispiel der Neuerung dargestellt, und zwar zeigen : Fig. 1 eine Madensohraube gemäß der Neuerung in Draufsicht und Seitenansicht, Fig. 2 eine Zylinderkopfschraube in den gleichen Ansichten, Fig. 3 einen Schraubenzieher gemäß der Neuerung in einer Seitenansicht mit aufgesetzter Madenschraube im Schnitt und Fig. 4 eine dazu senkrechte Ansicht des Schraubenziehers mit geschnittener Madensohraube. An exemplary embodiment of the innovation is shown in the drawing, namely: FIG. 1 shows a grub tube according to the innovation in plan view and side view, FIG Side view with set screw in Cut and 4 shows a view of the screwdriver perpendicular thereto with cut maggot incense.

Die Madenschraube 1 nach Fig. 1 weitet'in üblicher Weise einen Schlitz 2 auf. An ihn schließt sich eine Längsbohrung 3 an. Ebenso zeigt die Zylinderkopfsohraube 4 nach Fig. 2 einen Schlitz 5 und eine sich an seinen Grund anschließende Längs- bohrung 6. Der erfindungsgemäße Schraubenzieher 7 läßt ta Anschluß an seine durch Abflachungen 8 des Schaftes 9 gebildete Schneide 10 einen Zapfen 11 erkennen, dessen Abmessungen so gewählt sind, daß er in die Längsbohrungen 3 und 6 der Schrauben 1 bezw. 4 paßt. Demgemäß kann, wie die Fig. 3 und 4 zeigen, eine Schraube 1 auf den Zapfen 11 und die Schneide 10 aufgeschoben werden und wird auch bei Schrägstellung des Schraubenziehers, ja sogar dann gehalten, wenn der Schraubenzieher nach vorn geneigt ist.The grub screw 1 according to FIG. 1 widens a slot 2 in the usual way. A longitudinal bore 3 adjoins it. Likewise, the cylinder head tube 4 according to FIG. 2 shows a Slot 5 and a longitudinal adjoining its base hole 6. The screwdriver 7 according to the invention can be connected at its formed by flats 8 of the shaft 9 Cutting edge 10 recognize a pin 11, the dimensions of which are chosen so that it respectively into the longitudinal bores 3 and 6 of the screws 1. 4 fits. Accordingly, as shown in FIGS. 3 and 4, a screw 1 can be pushed onto the pin 11 and the cutting edge 10 and is held even when the screwdriver is tilted, even when the screwdriver is tilted forward.
