Abstract
A vibration-cushioned handle, to be clamped in at one end, is designed for an electrical tool or the like. The handle has a coupling at one end for firm attachment to the body of the tool, and a coaxial handle sleeve. At least one cushioned spring element is located between the sleeve and the coupling. The handle provides good reduction of vibration, and sufficient sturdiness of the handle connection on the other, while being of simple construction. To this purpose, the spring element has different spring rigidities, on the one side in the radial direction relative to the axis of the handle sleeve, and on the other side in the direction of a pendulous or Cardanic excursion of the handle sleeve, around a pole lying on their axis.
