Sandbag

Abstract

A sandbag is made of synthetic fibers, is an integral, woven, hollow and elongated element and has an upper cloth, a lower cloth, two lateral strengthened strips, a stuffing space and an inlet. The lower cloth is woven with the upper cloth. The lateral strengthened strips are respectively formed on two opposite sides of the sandbag and are integrally woven with where long sides of the upper cloth and the lower cloth are connected. The sandbag is produced as an integral element and has the lateral strengthened strips, so the structural strength of the sandbag is greatly enhanced and a lifespan of the sandbag is prolonged.

What is claimed is: 
     
         1 . A sandbag made of synthetic fibers, being an integral, woven, hollow and elongated element and comprising:
 an upper cloth having two opposite long sides and two opposite short sides;   a lower cloth located below the upper cloth and having
 two opposite long sides respectively and integrally woven with those of the upper cloth; and 
 two opposite short sides respectively connected with those of the upper cloth; 
   two lateral strengthened strips respectively formed on two opposite sides of the sandbag, radially protruding from and integrally woven with where the long sides of the upper cloth and the lower cloth are connected;   a stuffing space formed between the upper cloth and the lower cloth; and   an inlet connected with the upper cloth and communicating with the stuffing space.   
     
     
         2 . The sandbag as claimed in  claim 1 , wherein
 the opposite short sides of the lower cloth are respectively and integrally woven with those of the upper cloth; and   the sandbag further has two distal strengthened strips respectively formed on two opposite sides of the sandbag, axially protruding from and integrally woven with where the short sides of the upper cloth and the lower cloth are connected.   
     
     
         3 . The sandbag as claimed in  claim 2 , wherein
 the inlet is connected with the upper cloth by stitches.   
     
     
         4 . The sandbag as claimed in  claim 1 , wherein
 the short sides of the upper cloth and the lower cloth are connected by stitches.   
     
     
         5 . The sandbag as claimed in  claim 4 , wherein
 the inlet is connected with the upper cloth by stitches.   
     
     
         6 . The sandbag as claimed in  claim 1 , wherein
 two zippers are respectively connected with the lateral strengthened strips.   
     
     
         7 . The sandbag as claimed in  claim 2 , wherein
 two zippers are respectively connected with the lateral strengthened strips.   
     
     
         8 . The sandbag as claimed in  claim 3 , wherein
 two zippers are respectively connected with the lateral strengthened strips.   
     
     
         9 . The sandbag as claimed in  claim 4 , wherein
 two zippers are respectively connected with the lateral strengthened strips.   
     
     
         10 . The sandbag as claimed in  claim 5 , wherein
 two zippers are respectively connected with the lateral strengthened strips.   
     
     
         11 . The sandbag as claimed in  claim 1 , wherein
 each lateral strengthened strip has multiple through holes formed through the lateral strengthened strip.   
     
     
         12 . The sandbag as claimed in  claim 2 , wherein
 each lateral strengthened strip has multiple through holes formed through the lateral strengthened strip.   
     
     
         13 . The sandbag as claimed in  claim 3 , wherein
 each lateral strengthened strip has multiple through holes formed through the lateral strengthened strip.   
     
     
         14 . The sandbag as claimed in  claim 4 , wherein
 each lateral strengthened strip has multiple through holes formed through the lateral strengthened strip.   
     
     
         15 . The sandbag as claimed in  claim 5 , wherein
 each lateral strengthened strip has multiple through holes formed through the lateral strengthened strip.   
     
     
         16 . The sandbag as claimed in  claim 1 , wherein
 two connecting strips are respectively stitched with the lateral strengthened strips by stitches and each connecting strip has multiple through holes formed through the connecting strip.   
     
     
         17 . The sandbag as claimed in  claim 2 , wherein
 two connecting strips are respectively stitched with the lateral strengthened strips by stitches and each connecting strip has multiple through holes formed through the connecting strip.   
     
     
         18 . The sandbag as claimed in  claim 3 , wherein
 two connecting strips are respectively stitched with the lateral strengthened strips by stitches and each connecting strip has multiple through holes formed through the connecting strip.   
     
     
         19 . The sandbag as claimed in  claim 4 , wherein
 two connecting strips are respectively stitched with the lateral strengthened strips by stitches and each connecting strip has multiple through holes formed through the connecting strip.   
     
     
         20 . The sandbag as claimed in  claim 5 , wherein
 two connecting strips are respectively stitched with the lateral strengthened strips by stitches and each connecting strip has multiple through holes formed through the connecting strip.
