Abstract
A vertical aerial assembly for the volleyball includes a lower fixing rod, a lower screw member, an aerial, a handle, an upper screw member, and an upper fixing rod. 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.
