Description

CA 02793290 2012-09-14

GRAVITY-ASSISTED ROTATIONAL MECHANISM AND GENERATOR
DEVICE COOPERATING THEREWITH
BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a gravity-assisted rotational
mechanism and a generator device cooperating therewith. The
gravity-assisted rotational mechanism has precisely designed weight
arrangement. After an initial force is applied to the gravity-assisted
rotational mechanism to make it rotate, the gravity-assisted rotational
mechanism can continuously operate and the generator device is able
to absorb and store natural gravitational energy.

2. Description of the Related Art

A conventional decorative or entertaining self-rotating article such as a
top or a bamboo dragonfly is manually driven to swivel so as to achieve
visual effect and entertaining or educational or other added function.
However, the self-rotating article will contact the ground or air and
gradually turn from a fast rotating state to a still state due to friction.
The
lasting time of the rotation of the article varies with the article's own
configuration and weight arrangement.

The so-called "Newton' s cradle" is another often seen decoration
working in the Law of Conservation of Energy. A Newton's cradle


CA 02793290 2012-09-14

includes multiple metal balls suspended from a rack via strings. The
metal balls are originally still and arranged side by side. When a first
metal ball is lifted and then released and dropped to hit a second metal
ball, the kinetic energy is sequentially transmitted from the second metal
ball to a last metal ball. At this time, the last metal ball bounds up to
transform the kinetic energy into potential energy. The conversion
between the kinetic energy and the potential energy is repeated,
whereby the Newton' s cradle can lastingly operate.

The above self-rotating mechanism or decoration is driven by external
force or operate in the Law of Conservation of Energy. The above
decorations can be modified to have longer operation time and wider
application range. For example, in condition of minimum energy loss or
absorption of natural gravitational energy during operation, the
self-rotating article can operate more lastingly in different pattern to
achieve more novel and funny visual effect. In addition, a generator
device can cooperate with the self-rotating mechanism to supply
electrical energy.

SUMMARY OF THE INVENTION

It is therefore a primary object of the present invention to provide a
gravity-assisted rotational mechanism and a generator device
cooperating therewith. The gravity-assisted rotational mechanism has
sophisticated structure and is able to lastingly self-rotate.

To achieve the above and other objects, the gravity-assisted rotational
2


CA 02793290 2012-09-14

mechanism includes multiple concentric rotational members having
different sizes and rotatable about the same rotational center, several
link members having equal weights for driving the same, and at least
one connection member for pivotally connecting the rotational members
with the link members. The rotational members can symmetrically
push/pull each other. The link members and the connection member are
respectively mounted on interference sections of at least some of the
rotational members to transform the interference. The energy of the link
members is transmitted via the interference sections to the rotational
members and the connection member to form a cycle of energy
transmission and absorb gravitational energy during the cycle. In
condition of low energy loss, the gravity-assisted rotational mechanism
forms a continuously swinging and self-revolving device for lasting
watching.

In the gravity-assisted rotational mechanism, the torque applied to the
rotational members varies with the distances between the rotational
members and the rotational shaft. In a preferred embodiment, the
gravity-assisted rotational mechanism includes four metal rings with
different sizes. The four metal rings are concentrically arranged. When
the weight of a link member is applied to the rotational members, a
larger torque is applied to the rotational member that has a larger size
and is spaced from the rotational shaft by a longer distance. In this case,
the gravity-assisted rotational mechanism will revolve in a direction of
the torque applied to the larger rotational member. Accordingly, at least
one assembly of symmetrical link member and connection member is
arranged around the concentric rotational members to provide
3


CA 02793290 2012-09-14

complementary push/pull effect and achieve the objects of low power
loss and lasting rotation.

The generator device cooperating with the gravity-assisted rotational
mechanism is able to store the gravitational energy in the form of
electrical energy for prolonging the operation time of the gravity-assisted
rotational mechanism.

The present invention can be best understood through the following
description and accompanying drawings, wherein:

shaft 20. In addition, the link bars 302, 312, 322, 332 are respectively
formed with stabilization points 304, 314, 324, 334 for pivotally
connecting with the first pivot points 131, 132 of the rotational disc 13.
The inner ends of some symmetrical link bars 302, 322 additionally
have outward extending sections 3021, 3221 for pivotally connecting
with the second rotational ring 11. Moreover, different sections of the
link bars 302, 312, 322, 332 are respectively restricted within the first
and second interference sections 112, 101. Multiple rod-shaped
restriction members 34 are loosely fitted through the second
interference sections 101 and affixed to the link bars 302, 312, 322, 332.
The rod-shaped restriction members 34 are further fixedly fitted through
the first interference sections 112.

In a preferred embodiment, in order to keep the positional relationship
between the respective components of the gravity-assisted rotational
mechanism 1 in a good stabilized state in operation, multiple elastic
members 40, 41 are provided between the pivotal fitting sections 133,
134 of the rotational disc 13 and the push/pull sections 129 of the third
rotational ring 12 and between the restriction members 34 and the
rotational center or shaft 20. The elastic members 40, 41 serve to
provide elastic push effect to eliminate the loosening of the respective
components and the gaps therebetween so as to stabilize the operation
of the gravity-assisted rotational mechanism 1. In addition, the elastic
members 40 between the pivotal fitting sections 133, 134 of the
rotational disc 13 and the push/pull sections 129 of the third rotational
ring 12 serve to store the natural gravitational energy in the form of
elastic energy during the rotation to provide rotational assistance for the

third rotational ring 12. Also, the elastic members 41 between the
restriction members 34 and the rotational center or shaft 20 serve to
store the gravitational energy in the form of elastic energy during the
rotation to provide rotational assistance for the first rotational ring 10 so
as to enhance the ability to continuously rotate.

Please refer to Fig. 5. In a preferred embodiment of the present
invention, two gravity-assisted rotational mechanisms are assembled
with the same rotational center or shaft 20 with an angle difference. In
this case, the rotational inertia can be more smoothly continued.

Please now refer to Figs. 6 to 8. A working device or a generator device
is further connected to the rotational center or shaft 20 for converting
the stored gravitational energy into electrical energy and fully utilizing
the natural force as usable energy. The generator device 5 includes a
coupling wheel (or gear) 50 mounted on the rotational center or shaft 20.
The coupling wheel 50 is coupled with an actuation device 51 (such as
a motor) and a coupling section of a generator 52. The generator 52 is
further coupled with an electrical control device 53, which is electrically
connected to an electrical conversion device 54 (such as a rectifier or a
transformer) and a power storage device 55 (such as a battery). The
power storage device 55 can further provide electrical energy to
external devices or the actuation device 51 via the electrical conversion
device 54. Sensors 56 are disposed at the rotational center or shaft 20
and the central rotary shaft 522 of the generator 52 for measuring the
rotational speed to turn on the actuation device 51 again in proper time
and keep an optimal rotational speed for power generation. The power

storage device 55 can supply necessary power for the actuation device
51.

The above embodiments are only used to illustrate the present invention,
not intended to limit the scope thereof. Many modifications of the above
embodiments can be made without departing from the spirit of the
present invention.
