ABSTRACT:

FIELD OF THE INVENTION
The present invention generally relates to a balloon, and in particular to a fin structure of a balloon.
BACKGROUND OF THE INVENTION
Large balloons have been widely used for advertisement and other purposes.
FIG. 11
of the attached drawings shows an example of a conventional balloon having an airship-shape, designated by reference A. The balloon A has a number of tail fins B integrally formed with the balloon A whereby when the balloon A is inflated, air gets into the fins B and expands the fins B. The expanded or inflated fins B are kept in shape and position by the compressed air filled therein. Besides decoration, the fins B serve no purposes.
Thus, it is desired to provide a fin structure of a balloon which also serves to stabilize the balloon.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a fin structure of a balloon for stabilizing the balloon.
Another object of the present invention is to provide a fin structure of a balloon which is easily to assemble/disassemble.
To achieve the above object, in accordance with the present invention, there is provided a fin structure of a balloon comprising a frame having a pair of opposite and spaced support rods having first and second ends and a cross rod connected between first ends of the support rods. A flexible sheet of material is attached to the frame by having edges thereof forming passage fit over the support rods and the cross rod. Two connectors are mounted to the balloon for receiving and releasably retaining the second ends of the support rods thereby mounting the fin to the balloon.
