Hand-Held Tool With Rotary-Oscillatory Drive
First Claim
1. A hand-held tool comprising;
- a housing;
a gear head received within said housing;
a motor received within said housing and having a motor shaft that is rotatingly driven by said motor;
a tool spindle received within said housing substantially perpendicularly to said motor shaft and having one end protruding from said gear head for receiving a tool;
a carrier element received on said housing;
an eccentric coupling mechanism received within said housing, said eccentric coupling mechanism being coupled to said motor shaft and to said tool spindle for driving said tool spindle in an oscillatory rotating manner about a longitudinal axis thereof, said eccentric coupling mechanism comprising a coupling member being configured as a lever and being mounted pivotably on said carrier element, said coupling member being coupled to said motor shaft and to said tool spindle; and
a mass balancing arrangement being coupled to said eccentric coupling mechanism and being configured to impart to said eccentric coupling mechanism a balancing motion opposed to an oscillatory rotary output motion of said tool spindle.

Abstract
The invention discloses a hand-held tool having a housing with a gear head, having a motor shaft that can be driven in rotation by a motor and that can be coupled, by means of an eccentric coupling mechanism, to a tool spindle in order to drive the latter, wherein the tool spindle can be driven in an oscillatory rotating manner about the longitudinal axis thereof and is configured to receive a tool, wherein the eccentric coupling mechanism has a coupling member which is coupled to the motor shaft and to the tool spindle, and wherein the coupling member is furthermore mounted pivotably on a carrier element coupled to the housing. The carrier element is preferably capable of being moved in translation or pivoted relative to the housing.
