Patent ID: 8667697

Claim:
An eccentric gear arrangement of a motor-driven handheld hedge trimmer, the eccentric gear arrangement comprising: first and second shearing blades driven in mutual opposition to each other over a displacement path (a); said first and second shearing blades having respective first and second connecting links formed thereon and said connecting links lying directly one above the other; an eccentric wheel rotatably driven about a rotational axis; said eccentric wheel having a drive wheel defining a first side; said eccentric wheel further having first and second eccentrics arranged on said first side and engaging corresponding ones of said first and second connecting links; said first and second shearing blades having respective first and second contact pressure surfaces formed thereon in the region of said first and second connecting links; said first and second contact pressure surfaces being offset with respect to each other so as to cause said first and second contact pressure surfaces to be exposed over at least a portion of said displacement path (a); first and second downholders for acting on corresponding ones of said first and second contact pressure surfaces; said first and second shearing blades having respective shearing sections and respective rearward ends lying opposite said shearing sections in the direction of said displacement path (a); said first and second shearing blades further having first and second contact pressure extensions, respectively, arranged on the corresponding ones of said rearward ends and running parallel to said displacement path (a); said first and second contact pressure extensions being laterally offset with respect to each other in a lateral direction transverse to said displacement path (a); and, said first and second contact pressure surfaces being formed on corresponding ones of said first and second contact pressure extensions.
