Gas balloon having floating height control ability

Abstract

The present invention relates to a gas balloon with floating height control ability, more particularly, a gas balloon 1 capable of floating in air by static buoyancy of gas, comprising balloon member 2 and weight control member 4 of the balloon; wherein the balloon member 2 comprises reinforcement coating layer 6, silver coating layer 7 and outer surface fabric cloth 8 while said handle part 2 a has magnetic plate 3 therein to control the weight of the balloon 1, having large and small piece 5, 5 a. The gas balloon 1 according to the invention can keep its floating height to a constant level by removing said large and small piece 5, 5 a continuously to lead rising of the balloon 1, especially, even in case the balloon 1 which is used for long term gradually falls down since it causes gas filled in the balloon member 2 flowing out of the member as time goes by, thus, induces loss of the static buoyancy of the member 2.

1 . (Cancelled)  
   
   
       2 . A gas filled balloon having floating height control ability, which comprises: 
 a balloon member including;    a silver foil coating layer;    a reinforcement coating layer formed on the inside surface of the silver coating layer; and    a fabric cloth coating layer formed on the outside surface of the silver coating layer; and    a handle member connected to the lower end of the balloon member, said handle member including: 
 a magnetic plate;  
 a plurality of large magnetic members adapted to be magnetically attached to the magnetic plate; and  
 a plurality of small magnetic members adapted to be magnetically attached to the magnetic plate for selectively controlling the weight of the handle member so as to adjust the floatation height of the balloon member in the air.  
   
   
   
       3 . The gas balloon member according to  claim 2 , wherein the weight of the large and small magnetic members is about 0.2 g to 0.5 g.  
   
   
       4 . A gas filled balloon which comprises: 
 an inflated balloon member and a floating height control member containing a weight member extending from the lower portion of the balloon member,    said floating height control member including means for adjusting the weight of the weight member to control the flotation height of the balloon member.    
   
   
       5 . The gas filled balloon of  claim 4 , wherein the floating height control member is a magnetic plate containing magnetic pieces attached thereto which can be removed from or added to the magnetic plate.  
   
   
       6 . The gas filled balloon of  claim 4 , wherein the floating height control member is a weight member containing removable portions which can be removed as desired to adjust the flotation height.
