Embodiment Construction

[0018] Basically identical parts are marked with the same reference symbols.

[0019] figure 1 A detail of a hand-held power tool, not shown in further detail in the figures, is shown with a vibration-damping handle 10 having two legs 12 , 14 extending in the longitudinal direction 48 of the hand-held power tool and which is connected to the housing Body 28 is elastically coupled.

[0020] On one leg 12 , a lever 20 oriented transversely, here substantially perpendicularly, with respect to the longitudinal direction 48 of the hand-held power tool is articulated with one of its two ends at the joint point 16 and with its other end The articulation is at the articulation area 50 between the legs 12 and 14 of the handle 10 . Symmetrically to this, on the other leg 14 , the same lever 22 is articulated with one end at the articulation point 18 and with its other end likewise in the articulation region 50 . Here, the levers 20 , 22 pass through unmarked holes in the housing 28 t...

Abstract

The invention is based on a portable power tool having a vibration-damped handle (10) which has two legs (12, 14) running in the longitudinal direction (48) of the portable power tool and which is motionally coupled to its housing (28), wherein at least one lever (20, 22; 20a, 22a; 20b, 22b) oriented transversely to the longitudinal direction (48) is coupled to each of the two legs (12, 14) at an articulation point (16, 18; 16a, 18a), and wherein the levers (20, 22; 20a, 22a; 20b, 22b) are coupled to a joint region (50) lying between the two legs (12, 14) of the handle (10). It is proposed that each lever (20, 22; 20a, 22a; 20b, 22b) have a bearing point (24, 26; 24a, 20 26a; 24b, 26b) between the joint region (50) and the respective articulation point (16, 18; 16a, 18a).

Description

technical field [0001] The invention relates to a hand-held power tool with a vibration-damping handle. Background technique [0002] Especially in hand-held power tools with an impact drive, such as hammer drills, chisel hammers and similar devices, relatively strong vibrations can occur in the machine, which are transmitted to the handle of the machine and are not only uncomfortable for the operator , and may also be hazardous to health. [0003] DE 101 36 015 A1 discloses a hand-held power tool with a vibration-damping handle, which has two legs approximately parallel to the longitudinal direction of the hand-held power tool and is elastically coupled to the machine housing. One end of a lever substantially perpendicular to the longitudinal direction is articulated to each of the two legs of the handle, the other end of which is articulated in the hinge region of the machine housing between the two legs of the handle. Contents of the invention [0004] The invention r...
