SCHRAUBENDREHERSCREWDRIVER

Die Erfindung betrifft einen Schraubendreher mit einem Schaft, dessen beide Enden aus einem Handgriff herausziehbar sind. Die Zeichnung zeigt:The invention relates to a screwdriver with a shaft, both ends of which can be pulled out from a handle. The drawing shows:

Fig. 1 eine Explosionsdarstellung eines Schraubendrehers undFig. 1 an exploded view of a screwdriver and

Fig. 2 Schnitte durch den Schraubendreher zur Darstellung und 3 seiner doppelten Verwendung.Fig. 2 Sections through the screwdriver to illustrate and 3 its dual use.

In den Fig. 1 und 2 besteht ein Schraubendreher aus einem Handgriff mit zwei Hälften 20, 30, an denen Ansätze 21, 22 bzw. 31, 32 angeformt sind, durch welche Schrauben greifen, mit denen die beiden Hälften 20 und 30 aneinander befestigt werden.In Fig. 1 and 2, a screwdriver consists of a handle with two halves 20, 30, on which projections 21, 22 or 31, 32 are formed, through which screws engage, with which the two halves 20 and 30 are fastened together.

Zwei Kappen 46 und 47 sind an den Enden der beiden Hälften 20, 30 befestigt, um die beiden Hälften zusammenzuhalten. Die Griffhalften 20, 30 bilden einen Kanal 23, in dem ein Schaft 10 verschiebbar ist. Der Schaft 10 besitzt zwei Nuten 12 und 13 sowie zwei endseitige Ausnehmungen 14 und 15 zum Einsetzen von Schraubendreher-Einsätzen 16, 17, die aber auch an dem Schaft 10 angeformt sein können. Der Schaft 10 besitzt ferner zwei Anschläge 11 im mittleren Teil, die mit einer Feder 45 zusammenwirken, die den Schaft 10 in Fig. 2Two caps 46 and 47 are attached to the ends of the two halves 20, 30 to hold the two halves together. The handle halves 20, 30 form a channel 23 in which a shaft 10 can be moved. The shaft 10 has two grooves 12 and 13 and two end recesses 14 and 15 for inserting screwdriver bits 16, 17, which can also be molded onto the shaft 10. The shaft 10 also has two stops 11 in the middle part, which interact with a spring 45, which holds the shaft 10 in Fig. 2

nach links drückt. Der Handgriff 20, 30 weist zwei Ausnehmungen 24, 25 auf, in denen zwei Zungen 41, 42 und zwei Federn 43, 44 sitzen. Die Federn 43, 44 drücken die Zungen 41, 42 in jeweils eine Nut 12, 13 am Schaft 10.to the left. The handle 20, 30 has two recesses 24, 25 in which two tongues 41, 42 and two springs 43, 44 are seated. The springs 43, 44 press the tongues 41, 42 into a groove 12, 13 on the shaft 10.

Der Handgriff 30 besitzt ferner eine Öffnung 50, in der verschiebbar ein Knopf 51 sitzt, der eine Verlängerung 52 und einen Stift 54 aufweist, die jeweils in eine Ausnehmung 56 und eine Öffnung 57 im Block 55 greifen. Ein Steg 53 ist am Stift 54 befestigt. Eine Feder 61 ist an einem Zapfen 69 des Blockes 55 und einem Stift 60 am Handgriff 30 eingehängt, um den Block 55 in Richtung auf die Kappe 46 zu ziehen. Der Block 55 besitzt zwei Schrägflächen 58, an denen die Zungen 41, 42 anliegen, um die Zungen 41, 42 aus den Nuten 12, 13 des Schaftes 10 zu lösen (Fig. 2 und 3).The handle 30 also has an opening 50 in which a knob 51 is slidably seated, which has an extension 52 and a pin 54, each of which engages a recess 56 and an opening 57 in the block 55. A web 53 is attached to the pin 54. A spring 61 is hooked onto a pin 69 of the block 55 and a pin 60 on the handle 30 in order to pull the block 55 towards the cap 46. The block 55 has two inclined surfaces 58 against which the tongues 41, 42 rest in order to release the tongues 41, 42 from the grooves 12, 13 of the shaft 10 (Fig. 2 and 3).

Fig. 2 zeigt, daß die Zungen 41, 42 von den Federn 43, 44 derart in die Nuten 13 des Schaftes 10 gedrückt werden, daß der Werkzeugeinsatz 16 außerhalb des Handgriffs 20, 30 gehalten wird. In diesem Zustand ist die Feder 45 zwischen den Anschlägen 11 und der Kappe 4 6 zusammengedrückt.Fig. 2 shows that the tongues 41, 42 are pressed by the springs 43, 44 into the grooves 13 of the shaft 10 in such a way that the tool insert 16 is held outside the handle 20, 30. In this state, the spring 45 is compressed between the stops 11 and the cap 46.

Gemäß Fig. 3 werden die Zungen 41, 42 vom Schaft 10 über die Schrägflächen 58 des Blockes 55 fortbewegt, wenn der Block 55 vom Knopf 51 betätigt wird, derart, daß der Schaft nach links verschoben wird, so daß der Werkzeugeinsatz 17 aus dem Handgriff 20, 30 austreten kann. Die Zungen 41, 42 sind vorgespannt, um die anderen beiden Nuten 12 zu erfassen, wenn der Knopf 51 losgelassen wird, derart, daß der Werkzeugeinsatz 17 außerhalb des Handgriffs 20, 30 verbleibt. Der Schaft 10 kann vom Benutzer nach rechts verschoben werden, so daß die Zungen 41, 42 in die Nuten 13 eintreten können, sobald die Zungen 41, 42 aus den Nuten 12 mit Hilfe des Knopfes 51 gelöst worden sind.According to Fig. 3, the tongues 41, 42 are moved away from the shaft 10 over the inclined surfaces 58 of the block 55 when the block 55 is actuated by the button 51, such that the shaft is displaced to the left so that the tool insert 17 can exit the handle 20, 30. The tongues 41, 42 are preloaded to engage the other two grooves 12 when the button 51 is released so that the tool insert 17 remains outside the handle 20, 30. The shaft 10 can be displaced to the right by the user so that the tongues 41, 42 can enter the grooves 13 once the tongues 41, 42 have been released from the grooves 12 by means of the button 51.
