  • Patent number: 6412180
    Abstract: An anti-vibration element is provided for disposition between a motor unit and a handle unit of a manually guided implement. The anti-vibration element includes a sleeve-shaped, elastic main body as a vibration damper, with one end portion of the main body being adapted to be disposed in a receiving recess of the motor unit, and the other end portion being adapted to be disposed in a receiving recess of the handle unit. Respective plugs are disposed in the end portions of the main body for non-detachably holding such end portions in the receiving recesses. A cable that serves as a coupling element for preventing separation of the plugs is provided and spans an axial spacing between the plugs and extends through the main body. Each of the end regions of the cable has a respective fitting, an axially inwardly facing end face of each such fitting positively engaging behind an edge of an adjacent one of the handle unit and the motor unit.

  • Patent number: 6375171
    Abstract: The invention relates to a vibration damper between a housing (4), which holds an internal combustion engine, and a handle (3) fixed on the housing (4). The handle (3) is for holding and guiding the motor-driven chain saw (2) during use thereof. The vibration damper (1) is a coil spring (5) which is fixed at a first end (10) thereof with an attachment element (7) to the handle (3) and, at a second end (20), the coil spring is fixed with a further attachment element (30) to the housing. A part turn of the end (10, 20) of the coil spring (5) is held form-tightly to the attachment element (7, 30) in the direction of its longitudinal center axis (25). To provide a torsion-free assembly of the coil spring, it is provided that the coil spring (5) can be assembled from one of its ends (20) between the handle (3) and the housing (4) and be secured at least at one of its ends (20) to the attachment element (30) against a rotational movement in the peripheral direction.
