Soccer Ball Having Reinforced Strength
Abstract
A soccer ball includes a plurality of sheet plates connected
with each other and a plurality of reinforcement strips connected
with the sheet plates. Each of the sheet plates has a plurality of
connecting sides, and the opposite connecting sides of any two
adjacent sheet plates are connected to construct a plurality of
connections. Each of the reinforcement strips is bonded onto a
respective one of the connections to reinforce the strength of the
respective connection of the sheet plates. Thus, the reinforcement
strips encompass the connections of the sheet plates completely so
that the connections of the sheet plates are reinforced and limited
by the reinforcement strips to prevent the connections of the sheet
plates from being torn or broken due to a stress concentration so
as to enhance the lifetime of the soccer ball.

Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a ball and, more
particularly, to a soccer ball.
[0003] 2. Description of the Related Art
[0004] A conventional soccer ball 1 in accordance with the prior
art shown in FIGS. 1-4 comprises a plurality of sheet plates 11
connected with each other. Each of the sheet plates 11 has a
polygonal shape and has a plurality of connecting sides 111. The
opposite connecting sides 111 of any two adjacent sheet plates 11
are bonded and connected with each other by a high frequency to
construct a plurality of connections 13. In assembly, the opposite
connecting sides 111 of any two adjacent sheet plates 11 are bonded
and connected with each other by a high frequency to construct the
connections 13. Then, the redundant parts of the connections 13 are
cut and trimmed so that the connections 13 are flush with the sheet
plates 11. Thus, the sheet plates 11 are connected with each other
to form a soccer body. Then, the soccer body is inverted so that
the connections 13 of the sheet plates 11 are disposed in the inner
portion of the soccer body. Then, an air cell is inserted into the
inner portion of the soccer body. Finally, the edge of the soccer
body is sealed by a seal material to form the soccer ball 1. After
the air cell is inflated, the soccer ball 1 is expanded for use
with a user. However, when the soccer body is inverted, when the
air cell is inflated or when the soccer ball 1 is subjected to an
external force due to hit, the connections 13 of the sheet plates
11 are easily disconnected, torn or broken due to a stress
concentration, thereby decreasing the lifetime of the soccer ball
1.
BRIEF SUMMARY OF THE INVENTION
[0005] In accordance with the present invention, there is provided
a soccer ball, comprising a plurality of sheet plates connected
with each other and a plurality of reinforcement strips mounted on
and connected with the sheet plates. Each of the sheet plates has a
plurality of connecting sides. The opposite connecting sides of any
two adjacent sheet plates are bonded and connected with each other
to construct a plurality of connections. Each of the reinforcement
strips is bonded onto a respective one of the connections of the
sheet plates so as to reinforce the strength of the respective
connection of the sheet plates. Each of the reinforcement strips is
made a material the same as that of each of the sheet plates. Each
of the reinforcement strips has a length greater than or equal to a
length of the respective connection of the sheet plates. Each of
the reinforcement strips has a width greater than or equal to a
width of the respective connection of the sheet plates.
[0006] The primary objective of the present invention is to provide
a soccer ball having a reinforced strength.
[0007] According to the primary advantage of the present invention,
the reinforcement strips are securely bonded onto the connections
of the sheet plates so as to reinforce the strength of the
connections of the sheet plates so that the sheet plates are
combined to have a greater strength to withstand a larger force or
stress.
[0008] According to another advantage of the present invention, the
reinforcement strips encompass the connections of the sheet plates
completely so that when the soccer body is inverted, when the air
cell is inflated or when the soccer ball is subjected to an
external force due to hit, the connections of the sheet plates are
reinforced and limited by the reinforcement strips to prevent the
connections of the sheet plates from being torn or broken due to a
stress concentration so as to enhance the lifetime of the soccer
ball.
[0009] 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
[0017] Referring to the drawings and initially to FIGS. 5-7, a
soccer ball 2 in accordance with the preferred embodiment of the
present invention comprises a plurality of sheet plates 21
connected with each other and a plurality of reinforcement strips 3
mounted on and connected with the sheet plates 21.
[0018] Each of the sheet plates 21 has a substantially polygonal
shape and has a plurality of connecting sides 211. The opposite
connecting sides 211 of any two adjacent sheet plates 21 are bonded
and connected with each other by a high frequency to construct a
plurality of connections 23. Each of the reinforcement strips 3 is
made a material the same as that of each of the sheet plates 21.
Each of the reinforcement strips 3 is bonded onto a respective one
of the connections 23 of the sheet plates 21 so as to reinforce the
strength of the respective connection 23 of the sheet plates 21.
Each of the reinforcement strips 3 has a length 31 greater than or
equal to a length 231 of the respective connection 23 of the sheet
plates 21 and has a width 32 greater than or equal to a width 232
of the respective connection 23 of the sheet plates 21.
[0019] In the preferred embodiment of the present invention, each
of the reinforcement strips 3 is bonded onto the respective
connection 23 of the sheet plates 21 by a high frequency, an
adhesive, a glue, a heat blower and the like.
[0020] In assembly, the opposite connecting sides 211 of any two
adjacent sheet plates 21 are bonded and connected with each other
by a high frequency to construct the connections 23. Then, the
redundant parts of the connections 23 are cut and trimmed so that
the connections 23 are flush with the sheet plates 21. Thus, the
sheet plates 21 are connected with each other. Then, each of the
reinforcement strips 3 is bonded onto the respective connection 23
of the sheet plates 21. Thus, the reinforcement strips 3 are
combined with the sheet plates 21 to form a soccer body. Then, the
soccer body is inverted so that the reinforcement strips 3 and the
connections 23 of the sheet plates 21 are disposed in the inner
portion of the soccer body. Then, an air cell is inserted into the
inner portion of the soccer body. Finally, the edge of the soccer
body is sealed by a seal material to form the soccer ball 2. After
the air cell is inflated, the soccer ball 2 is expanded for use
with a user.
[0021] Accordingly, the reinforcement strips 3 are securely bonded
onto the connections 23 of the sheet plates 21 so as to reinforce
the strength of the connections 23 of the sheet plates 21 so that
the sheet plates 21 are combined to have a greater strength to
withstand a larger force or stress. In addition, the reinforcement
strips 3 encompass the connections 23 of the sheet plates 21
completely so that when the soccer body is inverted, when the air
cell is inflated or when the soccer ball 2 is subjected to an
external force due to hit, the connections 23 of the sheet plates
21 are reinforced and limited by the reinforcement strips 3 to
prevent the connections 23 of the sheet plates 21 from being torn
or broken due to a stress concentration so as to enhance the
lifetime of the soccer ball 2.
[0022] 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.
