  • Patent number: 8061438
    Abstract: The invention relates to a hand tool machine (2), in particular a drilling and/or percussion hammer, with a housing (4) and a vibration-damped handle (10) elastically supported relative to the housing (4) with two essentially parallel legs (20, 22) and a coupling element (44 or 46) between each leg (20 or 22) and the housing (4) that is pin-jointed to the leg (20 or 22) and the housing (4). The coupling elements (44, 46) are connected to each other by a connector (48) that synchronizes the movements of the coupling elements (44, 46).

  • Patent number: 7921935
    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).
