  • Patent number: 8127455
    Abstract: A portable implement is provided that includes a guide rod having a tool element arranged on one end and a motor for driving the tool element arranged on the other end. A holding element for holding the portable implement is arranged between the tool element and the motor. A connecting element is arranged on the guide rod or on the holding element, for connecting the holding element with the guide rod. The connecting element, in a first position of an operating element, is connected with the guide rod displaceably in a longitudinal direction on the guide rod. The connecting element, in a second position of the operating element, is releasably fixed on the guide rod.

  • Patent number: 7891099
    Abstract: A damped guiding unit for a portable implement includes a connection element arranged at one end of a guide rod element, for connection of a tool element for the sawing, cutting and/or scything of undergrowth or of grass. A damping element is arranged on the connection element for the damping of oscillations or vibrations caused by the tool element. A holding element is arranged on the guide rod element for holding the portable implement. The holding element and the connection element are structural elements which are respectively separated from each other in that the holding element is associated with a first assembly and the connection element is associated with a further assembly separated from the first assembly. The holding element is further arranged at a distance from the connection element between the one end and the other end of the guide rod element, so that both a direct guiding of the portable implement and also an intensive vibration damping of the holding element is achieved.
