Object guide having a variable motion path

摘要

The invention relates to an object guide having a variable motion path, which object guide comprises a first quadrilateral motion structure and a second quadrilateral motion structure. The first quadrilateral motion structure comprises a stationary leg and a first interface leg that can be moved in relation to the stationary leg. The second quadrilateral motion structure comprises an object carrier leg and a second interface leg that lies opposite the object carrier leg. The first and the second interface leg are connected to each other, wherein at least one of the legs of the first quadrilateral motion structure and/or of the second quadrilateral motion structure is variable with regard to a leg length. The object carrier leg moves tangentially or radially on the motion path when the first and the second interface leg are moved in relation to the stationary leg, wherein the shape of the motion path depends on the selected leg length.
