ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a self-generating wrist ball, and more particularly, to a roller ball which produces its own required energy created by impulse excitation at the rotation moment.
2. Description of the Prior Art
The wrist ball is a body-building apparatus with exercise fun. Its configuration, as shown in FIGS.
1
(A),
1
(B) and
1
(C), includes a ball-shaped housing
1
, a revolution ring
2
and a flywheel
3
. The ball-shaped housing
1
consists of a top housing
11
and a bottom housing
12
both of which are connected by radio frequency as one hollow body. The top housing
11
is provided with a circular opening
111
at the top thereof. The revolution ring
2
is disposed on support rim
121
on the inside of the top of the bottom housing
12
and rotatable thereon. Two connecting holes
21
are arranged at both sides of the support rim
121
. The flywheel
3
has a central shaft
31
pivotably connected to the connecting holes
21
of the revolution ring
2
so as to be received within the top and bottom housings
11
,
12
. An annular ridge
32
is disposed at the center of the surface of the flywheel
3
and provided with a through hole
321
.
Again, referring to FIGS.
2
(A),
2
(B) and
2
(C), a string
4
with one end inserted into the through hole
321
is then placed around the annular ridge
32
. Thereafter, when the string
4
is pulled out, the flywheel
3
rotates about the central shaft
31
within the revolution ring
2
.
As shown in
FIG. 3
, the ball-shaped housing
1
is held within the palm of the hand for rotation thereof. The flywheel
3
together with the revolution ring
2
orbits the ball-shaped housing
1
in addition to rotating along the annular ridge
32
. In other words, the flywheel
3
produces the effect of “rotation and revolution” within the ball-shaped housing
1
. The forces of these two rotations in two different directions create an inertia torsion moment. When the wrist controls the movement of the ball body, the ball body will create a torsional moment against the wrist. It's very marvelous. The wrist ball is not only supposed to exercise/strengthen wrist muscles, but also have fun like playing toys.
After the above-mentioned wrist ball has been developed, it has been over ten years that it was not changed and improved, thereby losing attraction degree by degree. Therefore, someone has tried to make the housing transparent while the flywheel
3
is provided with light fitting (e.g. LEDs). In use, the blazing rotational light is produced. However, the light fitting needs batteries to supply power. However, there are two drawbacks in installing batteries within the flywheel
3
:
1. The small battery is easily used up after few hours, thereby producing no light more. To ensure the safety, the top and bottom housings
11
,
12
are welded by radio frequency before leaving the factory so that the wrist ball can't be opened to put a new battery therein. Thus, the lighting duration is limited, thereby leading to discontent of the consumers because they have the feeling of being cheated.
2. Batteries cause pollution to environment. Therefore, an amount of pollution tax will be levied in some countries before installation of batteries into the wrist ball. As a result, it's also a factor that lighting wrist ball can't be spread.
It has been also tried to install a generating apparatus within the wrist ball. However, it fails because of its limited space. Thus, it's not easy to solve the problem with generating electricity. Even, it's more difficult for the wrist ball to continuously furnish the light fitting with electricity and to produce proper luminance. Consequently, the commercially available wrist ball has no successful self-generating example.
SUMMARY OF THE INVENTION
It is a primary object of the present invention to provide a self-generating wrist ball which is so designed as if a mini-generator is provided inside by means of impulse excitation created during the moment of the rotation of the wrist ball. Therefore, a self-generating effect during operation is created.
It is another object of the present invention to provide a self-generating wrist ball through which the problems with environmental protection caused by discarded batteries can be avoided.
It is a further object of the present invention to provide a self-generating wrist ball which continues to effectively produce electricity. Moreover, the light can be effectively concentrated to emit blazing beams. Besides, the generating mini-module won't affect the operation of the wrist ball inside.
