Definitions
- the present invention relates to a side handle for a hand tool.
- Hand tool machines transmit vibrations to a side handle.
- Damping elements in the side handle are intended to reduce an amplitude of the vibrations on a gripping surface.
- US 5,157,807 A describes such a handle.
- the vibration-damped side handle is a compromise between the ability to transfer forces of the user to the power tool and to reduce vibrations from the hand tool on the gripping surface. Transferring forces requires stiff, unyielding elements. Steaming, especially low frequency vibrations, requires soft, compliant elements.
- the inertia of the side handle may be increased by increasing its mass to improve damping. However, this increases the weight of the power tool.
- the inventive side handle for a hand tool includes a handle member and a fastening means for securing the side handle to the power tool.
- the gripping element and the fastening means are pivotable relative to each other about an axis of rotation.
- the axis of rotation runs perpendicular to a longitudinal axis of the grip element and extends through an end region of the grip element facing away from the attachment means.
- the user can grip the handle member near the end portion.
- the forces exerted by him, acting perpendicular to the handle element forces are transmitted to the fastener.
- Vibrations introduced via the fastener cause the handle member to vibrate.
- the amplitude of the vibrations is transmitted in a vibratory motion and dissipated their energy and / or the amplitude out of phase delivered to the vibrations again.
- An embodiment provides that an end region of the gripping element facing the fastening means has a restoring element for driving the gripping element back into a basic position with respect to the fastening means.
- the return element can be tuned to the frequencies of the vibrations that occur, so that the side handle acts as a absorber.
- a damper is resonantly excited by the vibrations and gives the vibrations phase-delayed and thus destructive to newly occurring vibrations again.
- the gripping element is a bearing which fixes the axis of rotation about the handle member is swingable, and that a connecting element connects the bearing with the fastening means.
- the connecting element can be stiff.
- the connecting element is arranged within the handle bar.
- the bearing has at least one elastic element which couples the connecting element with the handle element.
- the bearing described can be constructed simpler.
- the elastic element can enclose the connecting element in an annular manner.
- An embodiment provides that the bearing is formed by a solid-state joint in the connecting rod. As a result, the number of required elements is reduced, whereby in particular the assembly of the side handle is simplified.
- a restoring element is provided on an end region of the grip element facing the attachment means, which engages on the connection element and the grip element.
- the return element may be formed by a spring.
- the return element may be formed by a helical spring or spiral spring, which bears against a first surface of a first turn on the stylus element and with a second surface of a second turn on the connecting element. The second surface may be remote from the connecting element.
- One embodiment provides that an additional mass is attached to an end region of the grip element facing the attachment means.
- the additional mass increases the torque of the oscillating grip element. Due to the leverage effect is already achieved a large effect at a comparatively low mass.
- An embodiment provides that a center of gravity of the grip element lies outside a predetermined gripping surface.
- Fig. 1 shows a hand tool 10.
- the hand tool 10 may, for example, a drill, a chisel hammer, an electric screwdriver or a disc grinder instead of the percussion drill shown as an example.

- the gripping surface 18 may at least partially engage a user.
- a skin-friendly plastic may be injected around the handle bar 17, which forms the gripping surface 18.
- the gripping surface 18 may be formed according to the anatomical shape of a hand. A system for the grasping thumb and forefinger can thus be specified.
- the handle bar 17 may be formed hollow as a grip sleeve 19.

- a sealing element 27, for example a felt ring or a bellows, may be provided on the tension band 14, which seals a gap 28 between the tension band 14 and the first end 20.
- a spring 29 is provided at the first end 20 of the handle bar 17.
- the spring 29 exerts a force 30 substantially along the axis 15 of the connecting rod 26 on the handle bar 17.
- the spring 29 acts as a restoring element, which drives the handle bar 17 back into a basic position after a pivoting of the handle bar 17 relative to the connecting rod 26.
- the spring 29 can exert pressure and / or tensile forces.
- the spring 29 is designed to exert no force in a parallel position of handle bar 17 and connecting rod 26.
- a mass body 31 can be arranged.
- a mass of the mass body 31 is chosen such that the center of gravity 32 of the handle bar 17 is outside the gripping surface 18.
- the mass body 31 can be integrated within a slip guard 33 at the first end 20.
- a deflection of the handle bar 17 can be limited by stop elements 34.
- the stop element 34 may be formed, for example, by a projection on the connecting rod 26 or within the handle bar 17. The damping can in particular be prevented when the user pulls the power tool 10 away from a workpiece.
- the stop element 34 can be arranged asymmetrically with respect to the axis 15 on a side which points in the direction of action 16 of the handheld power tool 10 when the side handle 13 is fastened to the handheld power tool 10.
- An elastic buffer 37 may be arranged on the stop element 34 or on a surface 36 opposite the stop element 34.
- Fig. 3 shows a further embodiment of a side handle 38.
- the structure differs from that associated with Fig. 2 described side handle 13 among other things in the execution of the bearing 39 and the return element 40.
- the two embodiments can be combined with each other, for example by replacing the bearing and / or the return element.
- the bearing 39 consists of a first bearing shell 41, a second bearing shell 42 and a spring element 43.
- the first bearing shell 41 is formed by an end piece 44 of the connecting rod 26. In the end piece 44, a recess 45, for example, an annular or star-shaped recess 45 is introduced.
- the second bearing shell 42 may be formed by an inner contour 46 of the second end 21.
