Definitions
- the invention relates to an electric hand tool device such as a drill or Rotary hammer for at least partially rotating drive of a picked tool.
- the rotary hammers and other drilling equipment currently available on the market are for two-handed operation only designed. In practice, however, one-hand operation is often used. In particular During assembly work, a free hand is often used to hold one to be fastened Object, for holding another tool, a hole template or Dowels and screws etc. required.
- the operating handle of drilling devices designed for two-hand operation is far away away from the center of gravity of the drill, which makes a large one-handed operation Stress on the wrist and arm muscles results.
- the big one Distance from the operator's hand to the workpiece starting from the front Tool very difficult because a small change in angle on the wrist makes a big one Deflection at the tool tip causes.
- a drill for one-handed operation has an extension the tool axis arranged behind the drive and essentially to it vertically oriented operating handle as well as an armrest that protrudes backwards, in which the forearm assigned to the operating hand can be fastened with a cuff.
- a handheld power tool such as a drilling machine has one Operating handle arranged behind the drive and oriented essentially perpendicular to it as well as a forearm support protruding backwards, one, the operating hand assigned concave shape that partially encompasses the forearm.
- the invention has for its object a solution for a trained for one-handed operation To show electric hand tool, with which the operating hand from the dead weight the electrical hand tool device is relieved and also the attachment of the Tool can be done more precisely.
- Another aspect is an additional one Design for two-hand operation.
- the operating handle is essentially present in an electric hand tool device the center of gravity and at the lower rear end of the Housing an at least partially horizontal contact surface for the operator's hand assigned, forearm, which causes the weight at least partially on the forearm rests.
- the operating handle with a switch for controlling the electric hand tool device is advantageous combined.
- the electric hand tool device is further advantageous by a at the rear end of the Concave recess arranged around the forearm and encircling the forearm with respect to the angular position the tool axis feasible.
- a safety clutch that is responsive to the tool torque is advantageous to separate the drive from the tool holder to a, the counter torque of the Forearm assigned, set a relatively low limit torque, resulting in a Tool blockage is not critical for the user.
- the handheld power tool also with tools with large tool diameters that occasionally cause tool blockages can be used uncritically in one-hand operation.
- An advantageously additionally available side handle alternatively enables two-hand operation for tools with large tool diameters or workpieces that are difficult to machine.
- the side handle with a non-lockable switch button is also advantageous Switching the limit torque of the safety clutch to one for two-hand operation permissible higher value, which means that the second hand on Side handle must attack.
- the handheld power tool advantageously has an independent operation from the power supply Electric accumulators for energy supply, which are further advantageous in the rear part of the electric hand tool device are arranged, whereby their own weight essentially is picked up by the forearm.
- Fig. 1 as an electric hand tool device.
- an electric hand tool device 1 has in the front region of a housing 2 a tool holder 3 for a, not shown, at least partially around an axis A. rotating tool, one in the front area of the housing 2 near the tool holder 3 and thus in front of the focus of the electric hand tool device 1 below the Housing 2 substantially perpendicular to the axis A and thus in normal use vertically arranged control handle 4 with a control switch 5, one vertically to the operating handle 4 and to the axis A arranged side handle 6 with a switch button 7, one arranged in the rear area of the housing 2, in normal use partially horizontal, support surface 8 for resting on a forearm 10 of the operating handle 4 encompassing operator hand 11 with two guide surfaces 9 perpendicular thereto, which for the forearm 10 together with the support surface 8 at least partially Form concave trough for lateral guidance of the electric hand tool device 1, and an electric accumulator 12 arranged in the rear area inside the housing 2 on.
