Ceiling suspension arrangement exhibiting at least one crawler type ceiling unit as well as method of suspending the ceiling unit at a ceiling structure

A method of suspending or positioning at least one crawler type ceiling unit at a ceiling structure extending in at least two spatial directions for providing at least two degrees of freedom for at least two-dimensional positioning or two-dimensional motions of the crawler type ceiling unit in suspended manner headlong the ceiling structure in conjunction with actively moving the crawler type ceiling unit along the ceiling structure by actively re-orientating the crawler type ceiling unit's traveling direction, wherein the ceiling structure comprises a plurality of profile units extending in a first spatial direction, wherein the ceiling structure defines at least one structural regularity in a second spatial direction;

• wherein the crawler type ceiling unit is suspended by means of a plurality of suspension elements coupling the crawler type ceiling unit to the ceiling structure by means of coupling and decoupling kinematics depending on a relative motion of the ceiling unit with respect to the ceiling structure in at least said second spatial direction, wherein the suspension elements are attached to and guided by at least two circumferential tracks of the crawler type ceiling unit, wherein the circumferential tracks respectively define a specific path of circumferential motion of the respective suspension elements, thereby providing for decoupling kinematics which suspend and relatively move the respective suspension element with respect to the ceiling structure during a relative motion of the crawler type ceiling unit in said second spatial direction.
