Description
<Desc/Clms Page number 1>
Schraubenzieher.
Die Erfindung besteht in einem Schraubenzieher, dessen Griff aus einer gegenüber dem Schraubenzieherschaft verdrehbaren, auch der Grösse nach fingerhutartigen Hülse besteht. Eine Ausführungsform der Erfindung besteht darin, dass der Rand der fingerhutartigen Hülse um den Rand einer dieser entsprechend ausgestalteten, jedoch etwas grösseren und mit dem Schaft starr verbundenen Hülse derart umgebördelt ist, dass eine Verdrehung dieser beiden Hülsen gegeneinander möglich ist.
Die fingerhutartige Ausbildung des Griffes dient zum Einstecken eines Fingers, insbesonders des Zeigefingers der Hand, so dass die vorzugsweise geriffelte, drehbare Fassung des Schraubenziehers und damit dieser selbst mittels Daumen und Mittelfinger gedreht werden kann. Diese Ausbildung erleichtert das Ansetzen, d. h. die Zentrierung des Schraubenziehers durch das Handgefühl.
In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes dargestellt. a ist der Schraubenzieherschaft, b eine an letzterem starr befestigte fingerhutartige Hülse und c eine in diese eingesetzte ebenfalls fingerhutartige Hülse. Beide Hülsen sind an ihren Rändern bei d derartig durch Bördelung miteinander verbunden, dass sie leicht gegeneinander verdreht werden können.
PATENT-ANSPRÜCHE :
1. Schraubenzieher, dadurch gekennzeichnet, dass sein Griff aus einer gegenüber dem Schraubenzieherschaft verdrehbaren, auch der Grösse nach fingerhutartigen Hülse besteht.

Screwdriver.
The invention consists in a screwdriver, the handle of which consists of a thimble-like sleeve that can be rotated with respect to the screwdriver shaft. One embodiment of the invention is that the edge of the thimble-like sleeve is crimped around the edge of a sleeve designed accordingly, but somewhat larger and rigidly connected to the shaft, in such a way that these two sleeves can be rotated against each other.
The thimble-like design of the handle is used to insert a finger, especially the index finger of the hand, so that the preferably corrugated, rotatable version of the screwdriver and thus the screwdriver itself can be rotated with the thumb and middle finger. This training facilitates the preparation, i. H. the centering of the screwdriver by feeling the hand.
An exemplary embodiment of the subject matter of the invention is shown in the drawing. a is the screwdriver shaft, b is a thimble-like sleeve rigidly attached to the latter and c is a thimble-like sleeve that is also inserted into it. Both sleeves are connected to one another at their edges at d in such a way by crimping that they can easily be rotated against one another.
PATENT CLAIMS:
1. Screwdriver, characterized in that its handle consists of a thimble-like sleeve which can be rotated with respect to the screwdriver shaft.
