Abstract

A side-handle for a hand-held power tool includes a gripping element and a fastener for fastening the side handle to the hand-held power tool. The gripping element and the fastening means can be pivoted with respect to each other around a rotational axis. This rotational axis runs perpendicular to a longitudinal axis of the gripping element and runs through an end area of the gripping element facing away from the fastener.

First claim

What is claimed is:

1. A side handle for a hand-held power tool, comprising:
a gripping element; and
a fastener for fastening the side handle to the hand-held power tool, the gripping element and the fastener pilotable with respect to each other around a rotational axis, the rotational axis running perpendicular to a longitudinal axis of the gripping element and running through an end area of the gripping element facing away from the fastener, wherein the gripping element has a bearing defining the rotational axis around which the gripping element can be pivoted, a stiff connecting bar connecting the bearing to the fastener, the connecting bar being connected to the bearing at one end of the connecting bar and to the fastener at another end of the connecting bar, the bearing having at least one elastic element at the one end coupling the connecting bar connector to the gripping element wherein a further end area of the gripping element facing the fastener has a return element to drive the gripping element back into a basic position relative to the fastener;
wherein the return element is formed by a helical spring or a spiral spring that, with a first surface of a first coil, is in contact with the gripping element and which, with a second surface of a second coil, is in contact with the connecting bar.

2. The side handle as recited in claim 1 wherein the second surface faces away from the connecting bar.

3. The side handle as recited in claim 1 wherein the helical spring winds coaxially around the connecting bar.

4. A side handle for a hand-held power tool, comprising:
a gripping element; and
a fastener for fastening the side handle to the hand-held power tool,
the gripping element and the fastener pivotable with respect to each other around a rotational axis, the rotational axis running perpendicular to a longitudinal axis of the gripping element and running through an end area of the gripping element facing away from the fastener, the gripping element having a bearing defining the rotational axis around which the gripping element can be pivoted, the bearing and the fastener defining a first axis therebetween the longitudinal axis of the gripping elem de first axis,
a connector connecting the bearing to the fastener,
a further end area of the gripping element facing the fastener having a return element to drive the gripping element back into a basic position relative to the fastener, the return element being located within the gripping element and extending from the connector to an interior surface of the gripping element.

5. The side handle as recited in claim 4 wherein the connector is a connecting bar running between the bearing and the fastener entirely along the first axis.

6. The hand-held power tool as recited in claim 1 wherein the body has a handle and a tool receptacle, the side handle being closer to the tool receptacle than the handle is to the tool receptacle.
