Apparatus for preventing flags and banners from folding
BACKGROUND OF THE INVENTION 
     FIELD OF THE INVENTION 
     The present invention relates to an apparatus for preventing flags and banners from folding. In particular, the present invention allows a banner to rotate according to the wind direction, so as not to cause the banner to wrap around the flag pole. 
     PRIOR ART 
     In the past, all kinds of banners were tied fixedly to flag poles. Each such banner flies on its flag pole according to the wind direction. Although the method of tying such banners may be different, the shortcoming is the same. That is to say, when the wind changes direction, the banner changes the direction it flies according to the current wind direction. But, part of said banner folds around the flag pole when the banner changes the direction it flies when the wind changes direction. The functionality of the banner decreases because people cannot see clearly the content of the banner when it wraps around the flag pole. It is necessary to solve this problem which now requires unfolding the banner on the flag pole by manual means, especially the banners secured to car mounted flag poles. 
     OBJECTS OF THE INVENTION 
     It is the object of this invention to provide an apparatus to prevent banners from folding on flag poles. This apparatus comprises two rotating buttons for fixing the banner on the flag pole by respective button holes. When the wind changes direction, the banner can change direction according to the wind direction without wrapping the banner around the flag pole. 
     Another object of this invention is to provide such an apparatus having a low production cost. 
     SUMMARY OF THE INVENTION 
     An apparatus for preventing flags and banners from folding, comprises two rotating buttons and a set of bases secured on an upper portion of a flag pole. The flag banner is connected to the flag pole by the pair of rotating buttons. When the wind blows in a certain direction, the flag banner changes direction according to the wind direction, by means of the rotating buttons without wrapping the banner around the flag pole.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     As shown in FIGS. 1 and 2, the flag pole of this invention can be a telescoping type flag pole I or a conventional fixed length flag pole 1 (as shown in FIG. 3). The top portion 3 of the flag pole 1 has a connecting button 7 disposed thereon. The top portion 3 of the flag pole may have a conventional round ball 4 or some decoration 5, as shown in FIG. 5. Under the ball 4 or decoration 5, the top portion 3 of the flag pole is provided with an annular recess 6 in which a connecting button 7 can rotate. 
     Referring to FIGS. 2 and 4, the connecting button 7 has a large open round circular portion 8, its diameter being larger than the diameter of the annular recess 6, so that the connecting button can freely rotate in the annular recess 6. The circular portion 8 has an open section 10, so that it can expand and be coupled to the top portion within the annular recess 6. The connecting button also has a small circular portion 9 having an openable section for lockingly engaging the flag banner 11 by an upper banner hole 12, as shown in FIG. 7. 
     As FIGS. 1 and 2 show, the other connecting button 7 is connected to flag pole 1 by a base 14:. The base 14 comprises one upper connecting base 16 and one lower connecting base 15. The upper connecting base 16 has an annular recess 6 and external threads 17 for connection with a clamp 18 of lower connecting base 15 to thereby clamp the base 14 on the flag pole 1. 
     As shown in FIG. 7, the flag banner 11 has an upper button hole 12 and a lower button hole 13. The flag banner can be connected by the upper button hole 12 and the lower button hole 13 on the respective connecting buttons 7. As the wind blows in one direction, connecting buttons can rotate in the same direction so that the flag banner 11 will not be wrapped around the flag pole 1.
