摘要：
The movement system has an upper vertical section (1) and a lower vertical section (2), where the two vertical sections are connected with each other in an articulated manner. A horizontal section-foot platform (4) is connected with the lower vertical section in an articulated manner. A spring (7) provokes the two vertical sections for straightness.
