Definitions
- a disadvantage of the known hand tool is that due to the all-round spring effect on both Abfederungs Schemeen no adequate decoupling of the handle of the torsional vibrations occurring on the housing is possible. Rather, the spring behavior of both Abfederungs Schemee is superimposed with regard to the torsional vibrations. Due to the relatively stiff lower Abfederungs Schemees and the superposition with acting in the second direction spring action of the upper Abfederungs Symposiumes remains in operation a relatively high vibration along the second direction.
- the present invention has for its object to avoid the disadvantages mentioned in a generic hand tool and to reduce the vibrations transmitted to the handle as a result of torsional vibrations.
- the first spring device preferably has a first elastomer device which has on the first side of the first latch-shaped bearing element a prestressing region which has a multiple greater extent with respect to the first direction than a stopper region on the second side of the latch-shaped bearing element and that in the second direction both sides of the first latch-shaped bearing element has a permanent distance from the first tubular bearing element.
- the Elastomer device can be made for example of a foamed plastic, such as polyurethane in particular. In this way, a particularly favorable spring action on the biasing region can be achieved, which ensures a good decoupling and thereby a significantly reduced vibration transmission to the handle.
- two end-side elastomeric bodies 56 are provided, which are arranged in the installed state in each case between a side part 58 of the first housing-side bearing device 22 and a front-side flange 60 of the first tubular bearing element 26.
- a vibration reduction is also achieved in operation in the third direction x by at least partial decoupling of the first grip-side bearing device 28 from the first housing-side bearing device 22.
- two end-face elastomeric bodies 76 are also provided here, which are each arranged in the installed state between a side part 78 of the second housing-side bearing means 38 and an end flange 80 of the second tubular bearing element 42.
- a vibration reduction is also achieved in operation in the third direction x by at least partial decoupling of the second grip-side bearing device 44 from the second housing-side bearing device 38.
