Ball surface structure
Abstract
A ball surface structure includes multiple primary bosses each
having multiple secondary bosses formed on an outer periphery of
the primary boss and arranged in an annular format. Each primary
boss has a conical recess defined in the outer periphery of the
primary boss so as to increase surface friction with the ground
surface.

Claims
1. A ball surface structure comprising: multiple primary bosses
each having a conical recess defined in an outer periphery of the
primary boss so as to increase surface friction with a ground
surface.
2. The ball surface structure as claimed in claim 1, wherein
secondary bosses are formed on the outer surface of each of the
primary bosses.
3. The ball surface structure as claimed in claim 2, wherein the
secondary bosses are annularly formed on the outer periphery of
each of the primary bosses.
4. A ball surface structure comprising: multiple primary bosses
each having multiple secondary bosses formed on an outer periphery
of the primary boss and arranged in an annular format.
5. The ball surface structure as claimed in claim 4, wherein each
primary boss has a conical recess defined in the outer periphery of
the primary boss.
6. The ball surface structure as claimed in claim 5, wherein each
of the secondary bosses is integrally formed with one another so as
to form an annular ring on the outer periphery of the primary
bosses.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a ball surface structure,
and more particularly to a ball surface having multiple primary
bosses formed on the ball surface, multiple secondary bosses formed
on each of the primary bosses and a conical recess defined in each
of the primary bosses.
[0003] 2. Description of Related Art
[0004] Balls in different sport occasions may have bosses formed on
a ball surface. The reason the ball player is able to precisely
control the movement direction of the ball depends on the formation
of the bosses on the ball surface. That is, when the ball touches
the ground surface, the gaps between the bosses and sandwiched
between the ball surface and the ground surface create a suction
effect to the ball to hold the ball for a longer period of time
just before the ball bounces. During the prolonged time period, the
ball player is able to have a precise control of the ball. However,
to those balls that do not have any bosses formed on the ball
surface, the effect from the bosses is not visible and so that the
ball player may not be able to have a good control of the ball or
maybe the control of the ball is not so important. Still, even
though most balls do have bosses on the ball surface, the balls
still become slippery on rainy days. The water stays in the gaps
between the bosses on the ball surface, so that when the ball is
wet, the ball player is not able to control the ball precisely.
Furthermore, when the ball player dribbles on a watery ground
surface, the ball bouncing direction may not be the same as
expected due to the water between the ground surface and the ball
surface.
[0005] To overcome the shortcomings, the present invention tends to
provide an improved ball surface structure to mitigate the
aforementioned problems.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
a ball surface structure having multiple primary bosses on the ball
surface and multiple secondary bosses on each of the primary bosses
to increase engagement area with the ground surface.
[0007] In one aspect of the present invention, a conical recess is
defined in each of the primary bosses such that a suction effect is
created when the ball surface engages with the ground surface to
enable the ball player to have a precise control of the ball when
the ball bounces.
[0008] In yet another aspect of the present invention, an annular
ring is formed on each of the primary boss to increase the
engagement area with the ground surface.
[0009] Other objects, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.

invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0016] With reference to FIG. 1, it is noted that a ball in
accordance with the present invention is shown. The ball has
multiple primary bosses (1) formed on the ball surface to increase
friction with the ground surface when the ball bounces.
[0017] With reference to FIG. 2 to provide a better look at the
structure of the bosses (1) on the ball surface, it is noted that
each primary boss (1) has multiple secondary bosses (2) formed on
an outer surface of the primary boss (1).
[0018] With reference to FIGS. 3 to 6, it is noted that the
structure of the primary boss includes a conical recess (11)
defined in the outer periphery of the primary boss (1). Each
primary boss (1) has, in addition to the conical recess (11),
multiple secondary bosses (2) on the outer periphery of the primary
boss (1). Furthermore, each primary boss (1) may have multiple
secondary bosses (2) formed on the outer periphery of the primary
boss (1) in an annular format, as shown in FIG. 5, or an annular
ring (3) formed on the outer periphery of the primary boss (1) when
the secondary bosses (2) are integrally formed with one
another.
[0019] It is noted that no matter it is the secondary bosses (2),
the conical recess or the annular ring (3), the joint purposes of
the ball surface structure of the present invention is to increase
the surface friction when the ball engages with the ground surface
and to facilitate the expelling of water when the ball is used in
wet days.
[0020] It is to be understood, however, that even though numerous
characteristics and advantages of the present invention have been
set forth in the foregoing description, together with details of
the structure and function of the invention, the disclosure is
illustrative only, and changes may be made in detail, especially in
matters of shape, size, and arrangement of parts within the
principles of the invention to the full extent indicated by the
broad general meaning of the terms in which the appended claims are
expressed.
