Umbrella

Abstract

The present invention provides an umbrella consisted of a central stick, several ribs, and cover, wherein a fan stand is secured on the central stick, and connected with a motor box in hinge joint, said motor box holds a motor connecting with power, and a fan blade is secured on the axle of the motor. Due to adopting above-mentioned structure, the present invention attaches a mini electric fan to make the umbrella have two functions, as opening the umbrella, and turning on the fan simultaneously, the user not only enjoys shadow of the umbrella, but also feels the cool brought up by the fan.

I claim:  
     
         1 . An umbrella comprising a central stick, several ribs, and cover, wherein a fan stand is secured on the central stick, and connected with a motor box in hinge joint, said motor box holds a motor connecting with power, and a fan blade is secured on the axle of the motor.  
     
     
         2 . An umbrella as claimed in  claim 1 , wherein said fan stand is put on the central stick in fitting connection, and secured on the lower portion of the static center-coupled loop.  
     
     
         3 . An umbrella as claimed in  claim 2 , wherein the fan stand is combined of two half coordinating left-right pieces interlocked together by securing with bolts so that the retainer ring-groove on the upper portions of the left and right pieces holds the flange on the lower portion of the static center-coupled loop in, thereby to fasten the fan stand on the static center-coupled loop; the right piece has a battery box formed on the backside for mounting battery cells, and a through-hole drilled on it for leading cords out; the left piece has a lug formed on the backside for hinging a motor box on.  
     
     
         4 . An umbrella as claimed in  claim 3 , wherein the motor box is combined of upper and low cases covered together, and holds a motor in, and has a through-hole leading the axle of motor out; the low case has a lug with a wire hole, thereby to pivot on the lug of the fan stand with a pivot pin so that the motor box pivots on the fan stand.  
     
     
         5 . An umbrella as claimed in  claim 4 , wherein the fan stand has a blind hole approaching the root of the lug for putting a spring and a steel-ball sequentially in, and the lug of the motor box has more than one half-ball recesses on the outside rim, so that by means of the pressure of the spring the steel-ball latches into one of the recesses.  
     
     
         6 . An umbrella as claimed in  claim 5 , wherein between the two adjacent recesses of the lug of the motor box, there is a guide groove formed for guiding the steel-ball to slide from one recess to the next.  
     
     
         7 . An umbrella as claimed in  claim 4  to  claim 6 , wherein the cord connects the battery with one end; another end is wired through the wire-holes of the fan stand and the motor box to the motor.  
     
     
         8 . An umbrella as claimed in  claim 7 , wherein a fan-blade holder is fastened on the axle of motor, therein it is consisted of upper and low rests interlocked together; the upper rest has a central hole for securing on the axle of motor; 
 said fan blade is located on the fan-blade holder by locking the upper and low rests together in latching connection.    
     
     
         9 . An umbrella as claimed in  claim 8 , wherein said the fan stand has a combined retainer ring-groove on the upper portions of the left and right pieces holding the ring flange of the static center-coupled loop in exactly, thereby to fasten the fan stand on the static center-coupled loop.  
     
     
         10 . An umbrella as claimed in  claim 9 , wherein there is a step hole formed at inside of the contacting hole with the central stick of the fan stand for locating a releasing spring at inside so that the upper end of the spring presses against the bottom edge of the static center-coupled loop, and low end against on the shoulder of the step hole.
