Ball Game Net Rod Structure

Abstract

A ball game net rod structure includes a net body. The net body is supported by a net frame formed from lateral rods, upper rods and lower rods connected in series. Rod bodies of the upper rods or lower rods are wide V-shaped. A unidirectional connecting portion is disposed at two corresponding ends of the rod bodies. The unidirectional connecting portion includes a substantial D-shape, an arc disposed above the D-shape, and three straight sides connected thereto, or has at least a side with a narrow V-shaped indentation portion. When the paired rod bodies are connected, the connection is effectuated in only one direction. The unique direction ensures that tips of the wide V-shaped rod bodies point up or down to thereby stretch the net body or enable the net body to bear the brunt of a ball; hence, the net body is taut and pleasant when fully mounted.

What is claimed is: 
     
         1 . A ball game net rod structure, comprising:
 a net body supported by a net frame formed from lateral rods, upper rods and lower rods connected in series, characterized in that:   rod bodies of the upper rods or the lower rods are straight-rod or curved-rod shaped rod bodies, wherein unidirectional connecting portions corresponding in position to each other are disposed at a male connecting end and a female connecting end of the upper rods or the lower rods, wherein the male and female connecting ends of the paired upper rods or the paired lower rods are connected in one direction only, wherein, to connect the upper rods or the lower rods to the male or female connecting ends of the pipes or the sockets, the female or male connecting ends are connected in one direction only, wherein the unique direction ensures that tips of the wide V-shaped rod bodies point up or down to thereby stretch the net body, such that the net body is taut and pleasant when fully mounted.   
     
     
         2 . The ball game net rod structure of  claim 1 , wherein the unidirectional connecting portion comprises a substantial D-shape, an arc disposed above the D-shape, and three straight sides connected, wherein the male or female connecting ends of the paired upper rods or the paired lower rods are connected in one direction only, wherein, to connect the upper rods or the lower rods to the male or female connecting ends of the pipes or the sockets, the female or male connecting ends are connected in one direction only, wherein the unique direction ensures that the tips of the wide V-shaped rod bodies point up or down. 
     
     
         3 . The ball game net rod structure of  claim 1 , wherein the unidirectional connecting portion has at least a side with a narrow V-shaped indentation portion, wherein the male or female connecting ends of the paired upper rods or the paired lower rods are connected in one direction only, wherein, to connect the upper rods or the lower rods to the male or female connecting ends of the pipes or the sockets, the female or male connecting ends are connected in one direction only, wherein the unique direction ensures that the tips of the wide V-shaped rod bodies point up or down. 
     
     
         4 . The ball game net rod structure of  claim 1 , wherein the unidirectional connecting portion has at least a side with a narrow V-shaped protrusion portion, wherein the male or female connecting ends of the paired upper rods or the paired lower rods are connected in one direction only, wherein, to connect the upper rods or the lower rods to the male or female connecting ends of the pipes or the sockets, the female or male connecting ends are connected in one direction only, wherein the unique direction ensures that the tips of the wide V-shaped rod bodies point up or down. 
     
     
         5 . The ball game net rod structure of  claim 1 , wherein the unidirectional connecting portion is a pentagon formed from two parallel opposing sides and a bottom side perpendicular to the two opposing sides, wherein the male or female connecting ends of the paired upper rods or the paired lower rods are connected in one direction only, wherein, to connect the upper rods or the lower rods to the male or female connecting ends of the pipes or the sockets, the female or male connecting ends are connected in one direction only, wherein the unique direction ensures that the tips of the wide V-shaped rod bodies point up or down. 
     
     
         6 . The ball game net rod structure of  claim 1 , wherein curved-rod shaped rod bodies of the upper rods or the lower rods are wide V-shaped rod bodies. 
     
     
         7 . The ball game net rod structure of  claim 1 , wherein the two upper rods or the two lower rods are connected and fixed to each other by a pipe.
