Ball
Abstract
A ball has an internal bladder, an inner fabric layer, a
reinforcing layer, an outer fabric layer and an external cover
layer. The internal bladder is spherical and hollow. The inner
fabric layer is ventilative and soft, is mounted around the
internal bladder and allows air existing inside or outside the
inner fabric layer to pass through the inner fabric layer. The
reinforcing layer is mounted around the inner fabric layer. The
outer fabric layer is ventilative and soft, is mounted around the
reinforcing layer and allows air inside or outside the outer fabric
layer to pass through the outer fabric layer. The external cover
layer is mounted around the outer fabric layer. The ball with the
ventilative inner and outer fabric layers is highly elastic, soft
and deformable so the feel of hitting the ball is fine and
comfortable.

Claims
1. A ball comprising: an internal bladder being spherical and
hollow; an inner fabric layer being ventilative and soft, mounted
around the internal bladder and allowing air existing inside or
outside the inner fabric layer to pass through the inner fabric
layer; a reinforcing layer mounted around the inner fabric layer;
and an external cover layer mounted around the reinforcing
layer.
2. The ball as claimed in claim 1, wherein the reinforcing layer is
made of yarn and foam rubber.
3. The ball as claimed in claim 2, wherein the inner fabric layer
is made of cotton.
4. The ball as claimed in claim 3, wherein the external cover layer
is made of polyvinyl chloride.
5. The ball as claimed in claim 3, wherein the external cover layer
is made of polyurethane.
6. The ball as claimed in claim 1, wherein: the ball further
comprises an outer fabric layer being ventilative and soft, mounted
around the reinforcing layer and allowing air inside or outside the
outer fabric layer to pass through the outer fabric layer; and the
external cover layer is mounted around the outer fabric layer.
Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a ball, and more
particularly to a ball that is elastic, soft and deformable.
[0003] 2. Description of Related Art
[0004] Balls are used widely in various ball sports such as
basketball, soccer and football. A conventional ball has a bladder,
a reinforcing layer and an external cover layer. The bladder
receives compressed air. The reinforcing layer is made of yarn and
is mounted tightly around the bladder. The external cover layer is
mounted tightly around the reinforcing layer.
[0005] However, the conventional ball with the layers tightly
mounted together has a low elasticity and is too tough and people
who play the ball would feel uncomfortable.
[0006] To overcome the shortcomings, the present invention provides
a ball to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTION
[0007] The main objective of the invention is to provide a ball
that is elastic, soft and deformable.
[0008] A ball in accordance with the present invention comprises an
internal bladder, an inner fabric layer, a reinforcing layer, an
outer fabric layer and an external cover layer. The internal
bladder is spherical and hollow. The inner fabric layer is
ventilative and soft, is mounted around the internal bladder and
allows air existing inside or outside the inner fabric layer to
pass through the inner fabric layer. The reinforcing layer is
mounted around the inner fabric layer. The outer fabric layer is
ventilative and soft, is mounted around the reinforcing layer and
allows air inside or outside the outer fabric layer to pass through
the outer fabric layer. The external cover layer is mounted around
the outer fabric layer.
[0009] Other objectives, advantages and novel features of the
invention will become more apparent from the following detailed
description when taken in conjunction with the accompanying
drawings.
BRIEF DESCRIPTION OF THE DRAWINGS
[0010] FIG. 1 is a perspective view of a ball in accordance with
the present invention;
[0011] FIG. 2 is a partially exploded perspective view of the ball
in FIG. 1;
[0012] FIG. 3 is an enlarged cross sectional view of the ball in
FIG. 2; and
[0013] FIG. 4 is an enlarged cross sectional view of the ball in
FIG. 2 without the outer fabric layer.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] With reference to FIGS. 1 and 2, a ball in accordance with
the present invention comprises an internal bladder (10), an inner
fabric layer (20), and a reinforcing layer (30), an outer fabric
layer (40) and an external cover layer (50).
[0015] The internal bladder (10) is spherical and hollow and is
filled with compressed air.
[0016] The inner fabric layer (20) is ventilative and soft, may be
made of cotton, is mounted around the internal bladder (10) and
allows air (21) existing inside or outside the inner fabric layer
(20) to pass through the inner fabric layer (20).
[0017] With further reference to FIG. 3, the reinforcing layer (30)
may be made of yarn (31) and foam rubber (32) and is mounted around
the inner fabric layer (20).
[0018] The outer fabric layer (40) is ventilative and soft, may be
made of cotton, is mounted around the reinforcing layer (30) and
allows air (41) inside or outside the outer fabric layer (40) to
pass through the outer fabric layer (40).
[0019] The external cover layer (50) is made of polyvinyl chloride
(PVC) or polyurethane (PU) and is mounted around the outer fabric
layer (40).
[0020] When the ball is hit, the external cover layer (50) is
depressed to compress the air (41) between the external cover layer
(50) and the outer fabric layer (40). The compressed air (41)
inward passes through the outer fabric layer (40) and depresses the
reinforcing layer (30). The depressed reinforcing layer (30) then
compresses the air (21) between the reinforcing layer (30) and the
inner fabric layer (20) to inward pass through the inner fabric
layer (20). After a second, the air (21, 41) inside the inner and
outer fabric layers (20, 40) would outward pass through the inner
and outer fabric layers (20, 40) in order to achieve the pressure
balance between inside and outside spaces adjacent to each of the
inner and outer fabric layers (20, 40). The air (21, 41)
reciprocally passing through the inner and outer fabric layers (20,
41) makes the ball highly elastic, soft and deformable.
[0021] The ball with the ventilative inner and outer fabric layers
(20, 40) is highly elastic, soft and deformable so the feel of
hitting the ball is fine and comfortable. Furthermore, the
reinforcing layer (30) with the foam rubber (32) is firm and makes
the ball durable.
[0022] With reference to FIG. 4, the ball may be embodied without
the outer fabric layer (40) to lower the cost of the ball. The
inner fabric layer (20) still provides an excellent elastic and
soft effect.
