Title: Protecting structure for umbrella ribs

Description:
BACKGROUND OF THE INVENTION  
       [0001] When an ordinary umbrella without any anti-wind device is used, it would be broken if a strong upward wind occurs suddenly, after blowing the ribs of umbrella upward. If the umbrella is an upward collapsible one, it can be collapsed and then opened for use normally. If it happens to a stick type umbrella, which has straight ribs, the umbrella would be easily broken.  
       [0002] Accordingly, the primary object of the invention is to provide a protecting structure for a stick type umbrella, which uses an additional cord to connect the main rib and the relative stretcher for providing a force to resist the upward wind acting on the umbrella. Thus, the main rib will be prevented from being broken with this improved effect. Now the features and advantages of the present invention will be described in detail with reference to the accompanying drawings.

     [0005]FIG. 3 shows the umbrella of FIG. 2 being opened completely. 
    
    
     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
     [0006] Please refer to FIGS.  1  to  3 , the present invention mainly relates to an improvement of the stick type umbrella. A normal stick type umbrella includes a shaft ( 1 ), which is assembled with several sets of main ribs ( 2 ) and stretchers ( 3 ). The characteristic of the present invention is to provide a reinforced cord ( 4 ) between a middle position of the stretcher ( 3 ) and an outer position of the main rib ( 2 ). When the umbrella is not fully opened (FIG. 2), the cord ( 4 ) is just loose in the umbrella without any function. As the umbrella is opened (FIG. 3), the cord ( 4 ) will be drawn tightly between the main rib ( 2 ) and the stretcher ( 3 ) that provides a pulling force on the main rib ( 2 ). Hence, when upward wind happens, the main rib ( 2 ) can be pulled by the cord ( 4 ) for resisting the wind without damage.  
     [0007] Accordingly, the assembly of the present invention obviously achieves utility and improvement. It can be manufactured easily and provides a protecting effect on the straight rib of the umbrella.
