    (54) Vibration dampened machine handle


    (57) The machine handle has a hand part (3) which is connected with a source of vibrations (4) via two spring bushings (1, 2) of rubber. The rubber bushings (1, 2) consist of ring-­shaped rubber bodies (5, 5′) which surround an axle (6, 6′) and which are surrounded by a cover (7, 7′). The spring bu­shings (1, 2) er connected with an intermediate member (8, 9) such that the vibrations are transferred at an attenua­ted intensity from the source (4) of vibrations to the hand part (3) via the rubber bodies (5, 5′). The axes of the rubber bushings run in parallel with each other within a plane which is transverse to the direction from the source (4) of vibrations to the hand part (3). The ends of the hand part (3) are displaced in a parallel motion when they are pressed on instead of performing a pivotal motion whe­rein the angle is changed between the longitudinal axis of the hand part and the other parts of the machine tool.
