ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an apparatus for generating rotative force using a spring, more specifically the apparatus for generating rotative force using the spring, which is simplified in its configuration and increases convenience in use.
2. Background of the Related Art
A motor and engine are referred to as an apparatus for generating rotative force generally, and these means are applied to various fields of the industry.
However, as electricity or liquid/solid fuel is required to operate the apparatus for generating rotative force, the usage thereof is limited where the provision of electricity and fuel are difficult.
An apparatus for generating rotative force using spring is provided to solve the above problem, and the configuration thereof is as follows.
FIG. 9
is a sectional view for describing a rotative force generating process of a prior apparatus for generating rotative force using spring, and
FIG. 10

A reference numeral
101
,
102
, and
103
is a first, second, and third partition fixed by fastener
104
in order to have a predetermined interval.
An input shaft
105
is coupled rotatively through the first, second, and third partition
101
,
102
,
103
, one end of the input shaft
105
is projected to an outside of the first partition
101
, and in the projected end of the input shaft
105
a joining part
105
a
having a flat surface is formed.
On an outer circumference of the input shaft
105
between the first and second partition
101
,
102
, a spring
106
is wound spirally. An inner end of the spring
106
is fixed on the outer circumference, and an outer end of the spring
106
is fixed by being hooked over the fastener
104
fixing the first and second partition
101
,
102
.
To the input shaft
105
between the second and third partition
102
,
103
, a main gear
107
is coupled slidably, and to a side of the main gear
107
a ratchet wheel
108
is fixed.
A rotating plate
109
is fixed adjacent to the ratchet wheel
108
, an outer end of a blocking plate
110
is fixed to the rotating plate
109
, and an inner end of the blocking plate
110
is inserted elastically in a dedendum of the ratchet wheel
108
.
In the above configuration, as the input shaft is rotated counterclockwise (to the left), the inner end of the blocking plate
110
slides out from the ratchet wheel
108
thereby rotative force of the input shaft
105
is not transmitted to the main gear
107
, and as the input shaft is rotated clockwise, the inner end of the blocking plate
110
is locked in the dedendum of the ratchet wheel thereby rotative force of the input shaft
106
is transmitted to the main gear
107
.
Rotative force of the main gear
107
is increased by the first and second accelerating gear
111
,
112
, the increased rotative force is output through an output shaft
112
a
fixing the second accelerating gear
112
rotatively, and the rotating speed of the output shaft
112
a
is maintained constantly by a controlling means
113
.
The controlling means
113
comprises an accelerating gear
113
a
engaged with the second accelerating gear
112
, a ratchet wheel
113
b
rotated by the accelerating gear
113
a
, pendulum plate
113
c
installed rotatively adjacent to the ratchet wheel
113
b
, and a pair of blocking pin
113
d
fixed to the pendulum plate
113
c
and inserted in a dedendum of the ratchet wheel
113
b
repeatedly and sequentially.
These control means
113
control the rotating speed of the output shaft
112
a
by the operation, in which the pair of the blocking pin
113
d
slides along a tooth face of the ratchet wheel
113
b
rotating with the output shaft
112
a
and the blocking pin
113
d
is inserted in the dedendum of the ratchet wheel
113
b.
In trying to generating rotative force by the apparatus of the prior art, firstly with coupling a knob (not shown) to the joining part
105
a
, the input shaft
105
is rotated counterclockwise by external force.
In the above rotation of the input shaft
105
, as the inner end of the blocking plate
110
slides on the tooth of the ratchet wheel
108
, the rotative force of the input shaft
110
is not transmitted to the main gear
107
and the spring
106
is wound around the input shaft
105
so as to store the elastic rotative force.
As the input shaft is not rotated, the tooth of the ratchet wheel
108
locks the inner end of the blocking plate
110
. Therefore, there is no problem the input shaft is reverse-rotated rapidly by the elasticity of the spring
106
.
When external force is applied no more after rotating the input shaft by a certain number with knob, the input shaft
105
and the main gear
107
is rotated clockwise, and rotative force of the main gear
107
is increased by the first and second gear
111
,
112
and output through the output shaft
112
a.
Accordingly, the apparatus
100
as mentioned above is applied widely to the place requiring rotative force, as rotative force could be generated for quite long time.
However, since the apparatus
100
of prior art has the ratchet wheel
108
, the rotating plate
109
, the blocking plate
110
and the like to intermit rotative force of the input force
105
on the main gear
107
, the configuration thereof is not simple. Also, available time of rotative force is not indicated, the apparatus could be stopped during operation, so that the inconvenience of usage exists.
SUMMARY OF THE INVENTION
The present invention is contemplated to solve the aforementioned problem, and it is an object of the present invention to provide an apparatus for generating rotative force using spring, which could be provided with low cost by reducing a production cost due to the simplified configuration for intermitting rotative force of an input shaft and a spring to an output shaft, and also increases the convenience in use by indicating the available time of rotation and being stopped during operation.
To accomplish the above object, it is provided an apparatus for generating rotative force using spring having: an input shaft; a main gear to which rotative force is transmitted by the input shaft; a spring wound spirally on an outer circumference of a main gear shaft, an inner end of the spring being fixed on the outer circumference of the main gear shaft, an outer end of the spring being fixed on a predetermined position; accelerating gears installed to a lower part of the main gear to increase rotative force of the main gear; an intermitting gear for intermitting rotative force of the main gear to the accelerating gears by sliding up and down along the rotation direction of the main gear with being engaged with the main gear; an output shaft outputting rotative force increased by the accelerating gears; and controlling means controlling rotating speed of the output shaft constantly, wherein elastic rotative force is stored into the spring as the input shaft being rotated by external force and the output shaft is rotated by the elastic rotative force stored in the spring as the external force being removed from the input shaft, being characterized in that the intermitting gear is supported toward the accelerating gear by elastic force so that rotative force of the main gear is transmitted to the accelerating gears through the intermitting gear when the apparatus is inclined or upside down.
In addition, the control means includes: a ratchet wheel rotating together with output gear; a pendulum plate installed rotatably to an upper part of the ratchet wheel; and a pair of blocking projections formed integrally in a lower part of the pendulum plate toward the ratchet wheel to be inserted in the ratchet wheel sequentially and repeatedly.
Meanwhile, the available time of rotation in the output shaft is represented by an indicating means, and the indicating means includes: a first, second, and third deceleration gear reducing the rotating speed of the input shaft; an indicator rotating with the first, second, and third deceleration gear; and a number p
