摘要

The drive includes several planes articulated with respect to two lateral stringers through connecting rods and to an electric motor through two revolving bars. The bars are individually articulated relative to supports. The drive also has crosspieces for positioning of legs. In operation, each plane is moved along articulated and non-articulated positions by sliding relative to the associated stringer.
