         7 . Free-standing umbrella according to  claim 5 , wherein the canopy rods are linked to a stem section that can be displaced in telescoping fashion relative to the upright tube and supports a crown, where the crown and the runner move in opposite directions when opening and closing the umbrella as a result of at least one deflecting strut that is located above the runner and connected in articulated fashion to the upright tube at one end, and connected in articulated fashion to a canopy rod at the other end, and
 the ring manifold system is located between the supporting struts and the at least one deflecting strut in such a way that complete closing of the umbrella into the folded or collapsed position is not impaired.   
     
     
         8 . Free-standing umbrella according to  claim 7 , wherein for locking said umbrella in an upper position, the runner can be fastened in releasable fashion to one end of at least one of a retaining rod and a retaining rope, the other end of which is fastened to at least one of the crown and to the upper area of the displaceable stem section, and
 the ring manifold system includes at least one of a through hole and a lateral slit, through which at least one of the retaining rod and the retaining rope is guided in moving fashion.   
     
     
         9 . Free-standing umbrella according to  claim 8 , wherein the liquid feed line extends within the upright tube. 
     
     
         10 . Free-standing umbrella according to  claim 9 , wherein between four and sixteen spray nozzles are arranged around the upright tube with roughly equal angles between adjacent spray nozzles. 
     
     
         11 . Free-standing umbrella according to  claim 10 , wherein the spray nozzles display an atomizer nozzle at the end of a nozzle feed line. 
     
     
         12 . Free-standing umbrella according to  claim 11 , wherein the atomizer nozzle is directed in such a way towards the canopy that the direction in which the liquid is sprayed or atomized forms an angle between 0° and 45° relative to the horizontal. 
     
     
         13 . Free-standing umbrella according to  claim 1 , wherein said freestanding umbrella is designed as a collapsible umbrella that includes a runner displaceable along the upright tube to which supporting struts linked to canopy rods of the canopy are connected in articulated fashion, and that is designed in such a way that the ring manifold system is located between runner and canopy without impeding closing of the umbrella into the collapsed position.
