Definitions
- the currently known portable power tools in particular drills, impact drills, rotary hammers, screwdrivers, impact screwdrivers, etc., mostly have a switch handle that extends away from the motor housing in the form of a pistol. This shape has developed over the past few decades and is regarded as an optimal handle arrangement for many types of tools.
- the motor housing is gripped in the handle from behind with the hand, the thumb and forefinger placed on a circumferential recessed grip on both sides of the motor housing and pressed with the palm in the functional axis direction.
- the on-off switch is operated with a ring finger and a little finger. This results in optimal guidance of the power tool, because the forearm axis, motor axis and functional axis of the tool form an aligned line.
- the power tool is held with two hands. One hand grips the pistol-shaped switch handle, the other an additional handle. This additional handle is usually attached to the spindle neck of the power tool.
- the distance between the center switch handle and the center auxiliary handle should be approximately 25 cm. This allows the power tool to be guided very precisely, and the range of motion in the closed kinematic chain (tool-arm-body) is sufficiently large. For this reason, it has already been proposed for larger tools to attach the additional handle to the gear housing or to the intermediate bearing. This has the disadvantage, however, that these additional handles cannot be pivoted like those which are intended for the standardized spindle neck.
- a right-hander In previously known power tools, a right-hander has maintained an angle of approximately 100 ° to the functional axis with his right hand due to the predetermined inclined position of the pistol-shaped switch handle; with the left hand as a result of the specified additional handle an angle of 90. But from an orthopedic point of view, the same applies to the left as to the right hand. In its natural posture, ltae Hand assumes a position at an angle of approx. 100 ° to the functional axis.
- the object of the invention is to provide a power tool that allows the greatest possible freedom of movement in handling and at the same time is adapted to the natural hand position of the person. This problem is solved in that the power tool in several areas by spatial changes such as angles position and design.
- the handles are ergonomically optimized.
- the actuating element of the on-off switch not only around the lateral gripping surfaces of the pistol-shaped switch handle pull, but also partially around the motor housing above.
- a recess can be provided in the motor housing in which the actuating element can be displaced translationally in the direction of the finger-closing forces. This ensures that even smaller hands can encompass the power tool, as described above, during actuation of the switch and can also maintain this position.
- the pistol-shaped switch handle In order to achieve a similar optimal posture of the hand and forearm as with the screw described above, the pistol-shaped switch handle must also be in the area where the volar palm is rests in the same way as at the end of the motor housing. This ensures the greatest possible contact area between the handle and hand, which results in the greatest possible frictional engagement.
- the additional handle is connected to the clamp using a bracket.
- the bracket extends from the clamp mounted on the spindle neck, which is screwed onto the spindle neck, along the outer contour of the gear housing in the direction of the pistol-shaped switch handle to the additional handle.
- the additional handle In order to allow the hand on the additional handle to be ergonomically correct, it is arranged at an angle of approx. 20 ° to the switch handle.
- the new form of the power tool proposed here is of particular importance in the universally applicable devices which are now entering the market, since their use is not restricted to one area. For ver Different work must be able to take different grip positions.
- the power tool shown consists essentially of a gear housing 4 and a motor housing 7.
- the motor housing 7 merges into a pistol-shaped switch handle 22 on the side facing away from the gear housing 4.
- An intermediate bearing 5 is located between the motor housing 7 and the gear housing 4.
- An additional handle 13 is fastened on the spindle neck 2 with a clamp 3.
- a tool can e.g. B. by a drill chuck 1.
- the power tool is switched on and off by operating an actuating element 16 in a direction parallel to the functional axis 6.
- the actuating element 16 surrounds the outer surfaces of the handle 22 in a known manner in a shell-like manner on its side facing the switch handle 22.
- the operating member 16 protrudes with a web 14 in a recess 15 of the motor housing 7.
- the web 14 similar to the B-rich e adapted to the motor housing 7 of the gun-shaped switch handle 22nd On his the switch hand Handle 22 opposite end of the web 14 is formed so that it also covers the motor housing 7 at the end of the recess 15.
- a handle arrangement is provided in a known manner on the rear end of the motor housing 7 facing away from the transmission 4.
- the thumb and index finger can be placed in the recessed grip 8.
- the volar palm comes to rest on the back 10.
- the distance between the recessed grip 8 and the web 14 must be kept as small as possible, i. H. for large motors, the recess 15 must be chosen larger than for small motors. This reduces the relative movement between the two fingers that operate the actuating element 16 and the motor housing 7.
- a recessed grip 21 is arranged at the level of the actuating element 16, analogous to the recessed grip 8.
- a nose 20 and a back 23 are also arranged on the switch handle 22.
- the switch handle 22 is provided with an indentation 17 below the actuating element 16 up to a circumferential anti-slip device 19.
- a trough 18 enables the switch handle 22 to be enclosed by the last phalange.
- the switch handle 22 tapers in a wedge shape in the direction of the actuating element 16, so that both side surfaces form an angle of approximately 20 ° to one another. This takes into account the different sizes of the individual finger members, so that all fingers can be involved in supporting the tool weight.
- the additional handle 13 is connected to the clamp 3 via a bracket 11.
- the additional handle 13 is fastened in a conventional manner to the spindle neck 2 of the gear housing 4 by the clamping clamp 3.
- the bracket 11 extends along the outer contour of the gear housing 4 in the direction of the pistol-shaped switch handle 22.
- a damper around the additional handle 13 To give effect, the bracket 11 is arranged at a free distance from the gear housing 4. In order to be able to carry out this damping effect, the bracket 11 must consist of a material having a working capacity.
- the additional handle 13 is attached on the side of the bracket 11 facing away from the clamp 3, the additional handle 13 is attached. The type of attachment of the additional handle 13 on the bracket 11 can be selected so that a displacement of the additional handle 13 on the bracket 11 is possible.
- the additional handle 13 has the same angle with respect to the functional axis 6 as the pistol-shaped switch handle 22, but in the opposite direction.
- the switch handle 22, the functional axis 6 and the additional handle 13 form a downwardly open U, the legs 13 and 22 of which strive apart towards the opening.
- a protective bracket 12 is provided to secure the hand on the additional handle 13.
- the protective bracket 12 extends from the bracket 11 to the side of the auxiliary handle 13 facing away from the bracket 11.
- the protective bracket 12 can also be designed such that it only at the end of the auxiliary hand Handle 13 is attached and extends in the direction of bracket 11, but is not connected to this.
