BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a beach, patio, and particularly large size sun shading umbrella which may be on one single pole and more particularly to a sun shading umbrella with improved functionality such as maximizing the shading area, durability and weight for easy carrying capabilities. 
         [0003]    2. Description of Related Art 
         [0004]    The varieties of beach umbrellas presented on the market have limits for extending shaded area by simple size increase. The today existing constructions can&#39;t withhold the increase of the weight of components and a covering canopy with at least doubling the diameter of existing varieties of umbrellas. The increasing of the swiveling affect for the fabric supporting ribs leading to the collapse of the structure. 
         [0005]    Utility Pat. No. 6,758,228 discloses the in-folded umbrella. It is characterized for more compact size after folding.

     DETAILED DESCRIPTION 
       [0038]    The bi-folding increased coverage beach umbrella invention enables to increase shaded covering area to be increased up to double the size of conventional beach or recreational umbrellas on the single pole and yet the present invention achieves a minimum weight increase of the complete construction. These features allow the users to carry the folded increased coverage umbrella to a desired location with ease. 
         [0039]    The twin rail joint as shown in  FIG. 3  achieves extended sturdiness, and the twin-rail joint prevents the swiveling and collapse of the extended folding rod which may be loaded with an extended amount of covering canopy. The top pivot  14  and bottom pivot  15  may be guided by a pair of arms of the joint  13  during open/closed actions and stays open with limited swivels under different outdoor conditions shown in  FIG. 4 . 
         [0040]    The bi-folding increased coverage beach umbrella keeps the manufacturing processes simplified by using existing manufacturing constructions of conventional beach umbrellas by extending the frame assemblies with twin-rail joints  13  and the folding beam  5  shown in  FIG. 5 , 
         [0041]    The bi-folding increased coverage beach umbrella enables to have the increase size and can be divided in two sections to increase the ventilation for air flow in  221  in the shaded area and also to reduce the sail effect as illustrated in  FIG. 9 . Additionally, this construction withstands weather conditions, preventing the umbrella from turning inside out. The bottom pole  16  may include a drilling tip  19  shown in  FIG. 6  to drill the bottom pole  16  to the desired depth in the ground by rotating the handle  18 . The long handle bar  20  can be inserted into the hole  21  for the desirable length for easy operation. After inserting the top poll into the collar, the top poll is secured. 
         [0042]    The bi-folding increased coverage beach umbrella enables the angle of the extended curtain segments to be changed by position of a second latch  9  closer to the lower ring  12  as shown in  FIG. 11 . The present invention can display a logo by changing the angle of the extended curtain segments. 
         [0043]    It is an object of the present invention to provide a dual-folded umbrella having advantage of sturdy but still light weight construction with at least double the covering diameter as compared to the conventional beach or recreational umbrellas. 
         [0044]    It is another object of the present invention to provide for easy installation by driving the shank segment in the ground by extended multi-functional handle.
