Umbrella with cooling device

Abstract

An umbrella includes an upright central post along which a runner is movable. A crown is mounted to an upper end of the central post. A plurality of ribs is pivoted to and radially extending from the crown and each rib is linked to and driven by a stretcher having opposite ends pivoted to the runner and the rib respectively. A canopy is attached to and supported by the ribs whereby when the runner moves upward/downward along the central post, the canopy is selectively opened/closed. A cooling device includes a cylindrical casing partly constituting the central post but having a larger diameter defining an interior space in which a water tank containing an amount of water and a mist generator receiving water from the water tank and generating mist are accommodated. A tube conveys the mist to an outlet nozzle that is formed in the casing to direct the mist to a space under the canopy for cooling purposes.

1 . An umbrella comprising: 
 a frame comprising: 
 a central post,  
 a runner movably along the central post,  
 a crown mounted to an upper end of the central post,  
 a plurality of ribs each having an inner end pivoted to the crown,  
 a stretcher having ends pivoted to the runner and each rib respectively, and  
 a canopy attached to and supported by the ribs; and  
   a cooling device mounted to the frame to generate and direct mist to a space under the canopy for cooling the space.    
   
   
       2 . The umbrella as claimed in  claim 1 , wherein the cooling device comprises a casing defining an interior space in which a water tank containing an amount of water and a mist generator receiving water from the water tank for generation of mist are accommodated, at least one passage being formed between the mist generator and a mist outlet formed in the casing to convey the mist generated by the mist generator to the space under canopy.  
   
   
       3 . The umbrella as claimed in  claim 2 , wherein the water tank comprises a water inlet extending beyond the casing of the cooling device for replenishment of water into the water tank and a water level indicator adapted to be observed outside the casing for visual inspection of the amount of water inside the water tank.  
   
   
       4 . The umbrella as claimed in  claim 1 , wherein the cooling device comprises an electrically driven device comprising a power cord extending outside the casing for selectively connection with an external power source.  
   
   
       5 . The umbrella as claimed in  claim 2 , wherein the mist outlet comprises a nozzle for directing the mist to a desired position below the canopy.  
   
   
       6 . The umbrella as claimed in  claim 3 , wherein the water inlet comprises a cap removably mounted thereto.
