Title: Sand bag structure

Description:
BACKGROUND OF THE INVENTION  
      1. Field of the Invention  
      The present invention relates to a sand bag structure, and more particularly to a sand bag structure, wherein the two sides and the bottom of the main body are integrally combined with each other, and each of the two sides and the bottom of the main body has a determined width and thickness so as to enhance the support effect of the sand bag structure, thereby preventing the sand bag structure from being broken when containing the sand.  
      2. Description of the Related Art  
      A conventional sand bag in accordance with the prior art shown in  FIG. 3  comprises a main body  10  for containing sand and including two sides  12 , a bottom  14  connected to the two sides  12 . In fabrication, the two sides  12  of the main body  10  are formed by folding the main body  10 , and the bottom  14  of the main body  10  is formed by a stitching line  20 .  
      However, the stitching line  20  is easily torn or broken due to the weight of the sand, so that the sand falls out of the main body  10 . In addition, the two sides  12  of the main body  10  are easily worn out during a long period of time, thereby decreasing the lifetime of the conventional sand bag.  
     SUMMARY OF THE INVENTION  
      The primary objective of the present invention is to provide a sand bag structure, wherein the two sides and the bottom of the main body are integrally combined with each other, and each of the two sides and the bottom of the main body has a determined width and thickness so as to enhance the support effect of the sand bag structure, thereby preventing the sand bag structure from being broken when containing the sand.  
      Another objective of the present invention is to provide a sand bag structure, wherein the two sides and the bottom of the main body are integrally combined with each other, and each of the two sides and the bottom of the main body has a determined width and thickness so as to enhance the strength of the sand bag structure, thereby preventing increasing the lifetime of the sand bag structure.  
      A further objective of the present invention is to provide a sand bag structure, wherein each of the two sides and the bottom of the main body has a determined width and thickness, thereby facilitating the user taking and carrying the sand bag structure.  
      In accordance with the present invention, there is provided a sand bag structure, comprising a main body including two sides, and a bottom connected to the two sides, wherein: 
          the two sides and the bottom of the main body are integrally combined with each other;     each of the two sides of the main body has a determined width and thickness; and     the bottom of the main body has a determined width and thickness.        

      Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION  
      Referring to  FIGS. 1 and 2 , a sand bag structure in accordance with the preferred embodiment of the present invention comprises a main body  30  including two sides  40 , a bottom  60  connected to the two sides  40 , a first layer  70  mounted between the two sides  40  and the bottom  60 , and a second layer  80  mounted between the two sides  40  and the bottom  60  and separated from the first layer  70 .  
      Preferably, the two sides  40  and the bottom  60  of the main body  30  are integrally formed by a knitting process. In addition, each of the two sides  40  of the main body  30  has a strip shape and has a determined width and thickness. In addition, the bottom  60  of the main body  30  has a strip shape and has a determined width and thickness. In addition, an opening  90  is formed between the first layer  70  and the second layer  80  for containing sand therein.  
      Accordingly, the two sides  40  and the bottom  60  of the main body  30  are integrally combined with each other, and each of the two sides  40  and the bottom  60  of the main body  30  has a determined width and thickness so as to enhance the support effect of the sand bag structure, thereby preventing the sand bag structure from being broken when containing the sand. In addition, the two sides  40  and the bottom  60  of the main body  30  are integrally combined with each other, and each of the two sides  40  and the bottom  60  of the main body  30  has a determined width and thickness so as to enhance the strength of the sand bag structure, thereby preventing increasing the lifetime of the sand bag structure. Further, each of the two sides  40  and the bottom  60  of the main body  30  has a determined width and thickness, thereby facilitating the user taking and carrying the sand bag structure.  
      Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
