The invention relates to the handle assembly portable power tools, in particular electric angle grinders or the like.

When handling portable power tools, especially electric angle grinders, the hand-arm system of the user is exposed to heavy loads. The handle arrangement and design on these tools must therefore try to reduce the burden on the user as much as possible keep.

It is prior art that portable power tools 2 handles on opposite Ends of the machine to facilitate user control of the machine. Partially these handles are connected to one another by a web (US Pat. No. 28 10 240).

The unfavorable arrangement of the gripping surfaces causes the wrists to twist User and thus unnecessary static muscle work, which is an additional workload for the Noticeable to the user. Especially the handling for left-handers and the adaptation to different Arm spans of the tool users are not taken into account.

The invention is based on the object of creating a handle arrangement of the type described at the beginning with which not only better handling of the power-operated tool is achieved, especially for left-handers, but also better handling for different arm spans of the tool user. The object is achieved according to the invention in that one bracket (1) is arranged on the tool head side and the other bracket (2) is arranged on the tool foot side, the connecting web (3) is firmly connected to the tool housing (5 ') via a strut (4), the web-side Bracket ends (VX ") of the bracket (1) on the tool head side on the connecting web (3) and on the tool head (5") are pivotably mounted and can be locked in the pivot position and that finally the pivot axis (6) of the pivotable bow handle (1) with the drive axis (7) of the tool is in alignment

A further embodiment of the invention is characterized in that the dimensioning of the two bow handles increases on the hand contact surfaces, a hole-like formation (8) is located on the connecting web between the remaining bow ends, that the bow handle on the tool head side at the upper end (V) has a joint part ( 9) which enables a quick changeover and locking as well as that the front or rear bow handle is sloping

The handle assembly can be attached to various hand machine tools: Angle grinder. Angle polisher. Stone grinder, cutoff grinder. Hand drills, impact drills, rotary hammers, Construction screwdriver. Fastening screwdrivers, circular saws, Jigsaws. Hobelm & schineii, 3and grinder. Chainsaws. Tin snips, curved shears, nibblers. Fabric cutting machines.

The invention is explained using two drawings of an exemplary embodiment

F i g. 1 an electric angle grinder in common Arrangement of motor part (5 ') to gear part (5 ").

The rear bow handle part (2) is inclined towards the tool housing (5 '). The connection between the tool housing (5 ') and the rear bow handle part is produced by the cover part (10) which the handle is attached at the bottom. The front bow handle part (1) is inclined towards the tool head inclined This front bow handle part can be axially to Turn the axis of rotation (6) of the grinding wheel (7). The joint part (9) includes a lock by a Printing mechanism is released. The head-side bow handle part can be pivoted. Different positions can be taken (Fig. 2) (U). The lock engages due to the counter-pressure mechanism in the new position again. The connection between the head end and the rear bow handle part is made by the bracket web (3). The hole-like formation (8) on the strut (4) is used for Hang up the machine. The rear part of the bracket contains the on / off switch (12).
