TITLE: A POWER SUPPLYING DEVICE FOR AN EXERCISE BICYCLE
This invention relates to a power supply and in
particular to one for supplying power to the electronic
meter of an exercise bicycle.
It has been found that the conventional exercise
bicycle (stationary, recumbent, or semi-recumbent)
generally falls into two categories. The first one must
use alternating current power supply to provide
electricity for the electronic meter, while the other will
generate alterna~ing current by its own for supplying
electricity to the electronic meter. However, the
electronic meters of the first exercise bicycle will not
work wherever no alternating current power supply is
available. As for the other exercise bicycle, it is
necessary for the user to ride the second exercise bicycle
until the generator produces sufficient power for the
electronic meters before setting and/or adjusting the
electronic meter. In short, the user must ride the
exercise bicycle during the time when setting and/or
adjusting the electronic meter thereby causing much
~153~1~
inconvenience in operation.
Therefore, it is an object of the present invention
to provide a power supplying device for an exercise
bicycle which can obviate and mitigate the above-mentioned
drawbacks.
This invention relates to a power supplying device
for an exercise bicycle.
It is the primary object of the present invention to
provide a power supplying device for an exercise bicycle
which will switch on a rechargeable battery to supply
power to the electronic meter when the electric generator
does not supply sufficient power.
It is another object of the present invention to
provide an exercise bicycle which will charge a
rechargeable battery during the time when a user is riding
the exercise bicycle.
It is still another object of the present invention
to provide a power supplying device for an exercise
bicycle which enables a user to set and/or adjust the
electronic meters whenever he likes.

It is still another object of the present invention
to provide a power supplying device for an exercise
bicycle which is simple in construction.
It is still another object of the present invention
to provide a power supplying device for an exercise
bicycle which is easy to manufacture.
Other objects of the invention will in part be
obvious and in part hereinafter pointed out.
The invention accordingly consists of features of
constructions and method, combination of elements,
arrangement of parts and steps of the method which will be
exemplified in the constructions and method hereinafter
disclosed, the scope of the application of which will be
indicated in the claims following.

The invention is naturally not limited in any sense
to the particular features specified in the forgoing or to
the details of the particular embodiment which has been
chosen in order to illustrate the invention.
Consideration can be given to all kinds of variants of the
particular embodiment which has been described by way of
example and of its constituent elements without thereby
departing from the scope of the invention. This invention
accordingly includes all the means constituting technical
equivalents of the means described as well as their
combinations.
With reference to the drawings and in particular to
FIGS. 1, 2 and 3 thereof, the exercise bicycle 100
according to the present invention mainly comprises a pair
of pedals 11, a driving wheel 17, a driven wheel 16,
an electronic meter 12, a flywheel 13, an alternating
current generator, a rechargeable battery 19, and an
electrical circuit.

As shown in FIGS. 2, 3 and 4 the pedals 11 is
connected with the driving wheel 17 by any conventional
means well to those skilled in the art. The driven wheel
16 is connected with the driving wheel 17 by a belt or the
like. The flywheel 13 is attached to the a hub 18 for
uniformity of motion of the exercise bicycle. The
alternating current generator includes a plurality of
magnets 14 mounted on the inner side of the flywheel 13
and a stator 15 installed on the hub 18. The magnets 14
are arranged so that the south pole of one of the magnets
14 is affixed on the inner side of the flywheel 13 while
the north pole of an adjacent one of the magnets 14 is
mounted on the inner side of the flywheel 13. That is,
the south and north poles of the magnets 14 are
alternately fixed on the inner side of the flywheel 13.
The stator 15 includes a plurality of radial rods and a
plurality of solenoids 16 with clockwise winding and
counterclockwise winding. Each of solenoids 16 is mounted
on one of the radial rods. The solenoids 16 are designed
in such a way that the solenoids 16 with clockwise winding
2153~19
and the solenoids 16 with counterclockwise winding are
alternately mounted on the radial rods of the stator 15.
Hence, when the flywheel 13 is rotated, the magnets 14
will be rotated therewith thus making the solenoids 16
along with the stator 15 cut through the lines of force of
the magnets 14 and therefore generating an alternating
current.
FIG. 5 illustrates a generalized block diagram of the
present invention. As shown, an electrical circuit is
1~ connected between solenoids 16 of the alternating current
generator and the electronic meter by any conventional
means well known to those skilled in the art. The
electrical circuit includes a rectifying circuit, a first
voltage regulating circuit, a second voltage regulating
circuit, a voltage detector, a relay, and a rechargeable
battery. When an user begins to ride the exercise
stationary bicycle, the alternating current generator does
not provide sufficient working power for the electronic
meter 12, but the electrical circuit will switch on the
rechargeable battery 19 to supply electricity to the
~15391~
electronic meter. As the generator produces sufficient
working power for the electronic meters, the electrical
circuit will switch off the rechargeable battery and make
the generator charge the rechargeable battery 19.
S Accordingly, the user may set and/or adjust the electronic
meter whenever he likes thereby making it very convenient
in use.
The invention is naturally not limited in any sense
to the particular features specified in the forgoing or to
the details of the particular embodiment which has been
chosen in order to illustrate the invention.
Consideration can be given to all kinds of variants of the
particular embodiment which has been described by way of
example and of its constituent elements without thereby
departing from the scope of the invention. This invention
accordingly includes all the means constituting technical
equivalents of the means described as well as their
combinations.
