The vertical aerial assembly has a simplified construction with fewer parts, thereby decreasing the cost of fabrication. In addition, the vertical aerial assembly is assembled easily and conveniently, thereby saving the time of assembly. Further, the handle only needs to form a through hole to fit the outer diameter of the aerial without having to additionally provide a stepped hole, thereby decreasing the cost of fabrication.
Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates to a vertical aerial assembly for a volleyball net assembly, and more particularly to a vertical aerial assembly that has a simplified construction with fewer parts, thereby decreasing the cost of fabrication.




2. Description of the Related Art




A conventional vertical aerial assembly for a volleyball net assembly in accordance with the prior art shown in

FIGS. 1-3

comprises a rod


80


, a lower nut


81


, a lower fixing member


82


, a handle


83


, an aerial


86


, an upper nut


84


, an upper fixing member


85


, and an urging member


842


.




The rod


80


has a first end formed with an enlarged head


801


and a second end formed with an outer thread


802


and a pin hole


803


for insertion of a pin


804


. The lower nut


81


is formed with an inner thread


811


screwed on the outer thread


802


of the rod


80


. The lower fixing member


82


is mounted on the rod


80


and retained by the pin


804


. The lower fixing member


82


is provided with a lower fixing hook


821


. The handle


83


is mounted on the rod


80


, and has one end formed with a stepped edge


831


for stopping the enlarged head


801


of the rod


80


. The aerial


86


has one end secured in the handle


83


. The upper nut


84


is secured on the aerial


86


, and is formed with an outer thread


841


. The upper fixing member


85


is mounted on the aerial


86


, and has a first end formed with an inner thread


853


screwed on the outer thread


841


of the upper nut


84


, and a second end formed with a slideway


851


and provided with an upper fixing hook


852


. The urging member


842


is mounted on the aerial


86


, and is slidable on the slideway


851


.




In operation, the lower nut


81


is rotated, and the inner thread


811


of the lower nut


81


is screwed on the outer thread


802


of the rod


80


, so that the lower nut


81


is moved from the position as shown in

FIG. 2

to the position as shown in

FIG. 3

where the lower nut


81


is rested on the inner side of the lower fixing hook


821


of the lower fixing member


82


. Then, the handle


83


is rotated. At this time, the handle


83


and the upper nut


84


are secured on the aerial


86


. Thus, when the handle


83


is rotated, the upper nut


84


is rotated by rotation of the handle


83


, and the outer thread


841


of the upper nut


84


is screwed into the inner thread


853


of the upper fixing member


85


. At the same time, the urging member


842


is pushed by the upper nut


84


to slide on the slideway


851


, so that the urging member


842


is moved from the position as shown in

FIG. 2

to the position as shown in

FIG. 3

where the urging member


842


is rested on the inner side of the upper fixing hook


852


of the upper fixing member


85


.




In assembly, each side of the net (not shown) has a first end clamped between the lower nut


81


and the inner side of the lower fixing hook


821


of the lower fixing member


82


, and a second end clamped between the urging member


842


and the inner side of the upper fixing hook


852


of the upper fixing member


85


. Thus, the vertical aerial assembly for the volleyball is mounted on each side of the net.




However, the conventional vertical aerial assembly for a volleyball net assembly in accordance with the prior art has the following disadvantages.




1. The handle


83


needs to form a hole to fit the diameter of the aerial


86


and to form a stepped edge


831


to fit the size of the enlarged head


801


of the rod


80


, thereby increasing the cost of fabrication.




2. The conventional vertical aerial assembly for a volleyball net assembly has a complicated construction with many parts, thereby increasing the cost of fabrication.




3. The conventional vertical aerial assembly for a volleyball net assembly needs to provide a push member


842


and to provide a slideway


851


on the upper fixing member


85


for receiving the push member


842


, thereby increasing the cost of fabrication.
