  • Patent number: 9162352
    Abstract: A hand-guided apparatus may include an operating lever, a switch, and an intermediate lever. The operating lever may actuate a function of the hand-guided apparatus, be constructed in an elongated manner and be pivotably attached to a housing of the apparatus. The switch actuates the function and is arranged in the housing. The intermediate lever mechanically actuates the switch. The operating lever includes a safety element enabled to be pretensioned and shifted along a longitudinal axis of the operating lever. The operating lever and the intermediate lever are enabled to be mechanically coupled by shifting the safety element into a pretensioned state to enable actuation of the switch by pivoting of the operating lever. The operating lever and the intermediate lever are enabled to be mechanically decoupled by shifting the safety element into a relaxed state to prevent actuation of the switch by pivoting of the operating lever.

  • Patent number: 8732959
    Abstract: The invention relates to a motor-driven cutting device with a double blade arrangement driven by means of a double eccentric arrangement having opposing oscillating blade movement, comprising an advantageous construction with a separate double eccentric group for the drive device that can form a uniformly operable front-part group, particularly in conjunction with the double blade arrangement at a particularly favorable cost, and that is advantageous for installing the front-part group in the production process and/or when replacing the preferably uniformly operable front-part group.

  • Publication number: 20120167741
    Abstract: A blade for a hedge trimmer comprises a plurality of cutting teeth, each tooth having a longitudinal axis extending laterally away from the long axis of the blade, each cutting tooth comprising a root and a tip and opposing sides extending between the root and the tip, characterised in that at least one of the cutting teeth comprises a special tooth which is sharpened along at least one flank to form a cutting edge which extends to the free end of the tooth, and further in which the free end of the special tooth includes a connecting edge which extends from one flank of the tooth to the other and at least one part of which is inclined at an angle of between 4 degrees and 20 degrees relative to the long axis of the blade.

  • Publication number: 20120167395
    Abstract: A blade 1 for a hedge trimmer having a long axis and comprising a plurality of cutting teeth, each tooth having a longitudinal axis extending laterally away from the long axis of the blade 1, each cutting tooth comprising a root and a tip and opposing sides extending between the root and the tip, characterised in that at least one of the cutting teeth comprises a special tooth which is sharpened along at least one side to form a cutting edge, in which a first portion of the cutting edge is bevelled such that a tangent line to the first portion is inclined at an angle of between 1 degrees and 6 degrees relative to the longitudinal axis of the tooth, and a second portion of the cutting edge closer to the tip of the tooth than the first portion and which is bevelled such that a tangent line to the second portion is inclined at an angle relative to the longitudinal axis of the tooth of between 8 degrees and 25 degrees.
