#CMT# #/CMT# The system has a transforming unit transforming a rotation movement in a direction of one of linear and surface rigid elements (101, 102) e.g. bars, into another rotation movement in a direction of another element, where the system is folded and unfolded with respect to a reference e.g. wall. The directions are opposite to each other. An assembling unit (107) assembles a point (108) of the element (102) around an axis (118). A guiding unit (119) guides the point along a path (109). A force creating unit (110) creates reaction force (Fcr) in the point along a direction non tangent to the path. #CMT#USE : #/CMT# Rigid element system e.g. accordion type shutter system for closing an opening e.g. window or door, of a building and for covering and protecting a swimming pool or veranda. #CMT#ADVANTAGE : #/CMT# The system permits homogenization movements of the rigid elements in a simple manner without using large number of pieces. The system has reduced encumbrance in folded position. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic representation of a foldable and unfoldable rigid element system.
