Description

The present invention relates to a tool handle for drill drivers with a double-crowned handle.

In a known tool handle of this type, two convex handle handles of different sizes are arranged one behind the other in the longitudinal direction, which have the task of designing the handlebars particularly inexpensively due to the double convexity for the Zagriff> Iner Hand (U.S. Patent 1250 508). Drill wrenches with a .1 tool handle of the known type are often handled in practice in such a way that the double-sided handle is supported on the inside of the palm. You can work most effectively when the longitudinal axis of the drill and the operator's forearm are in alignment. Now, however, work incidents often occur. where one cannot pick up the tool in this way due to lack of space, ie when one cannot put the operating hand on the tool handle from behind in order to increase the working pressure in the usual way. It is then necessary to grip the tool handle so that the longitudinal axis of the tool is approximately perpendicular to the forearm of the operator's hand. It goes without saying that in most cases the required work force cannot easily be transferred to the tool by hand.

This object is achieved according to the invention in that each bale has a complete handle büdet "to which the corresponding hand goes sideways un-n-Wt Z-> eriff shark. This means that every bale of the doppelba in a tool booklet as a fully-fledged handle

Claims (3)

Patent claims: 1. Tool handle for drill screwdrivers with double-crowned handle, characterized in that that each ball (11, 12) forms a complete handle to which the associated hand has unimpeded access laterally. 2. Tool handle for drill screwdrivers according to claim 1, characterized in that the bales (11, 12) have approximately the same arch height. 3. Tool handle for drill screwdrivers according to claim 1 or 2, characterized in that there is a bead (16) on the handle side, which has at least one secantial flattening on the circumference (14). The invention is now the object zuorunde a tool for stitching Dnllschrauber with doppelballiger handle of the above described A _1? u create in which both hands next to each other can attack without interfering with each other.
