Abstract

An exercise bicycle having an electronic meter and an alternating current generator, characterized by a rechargeable battery electrically connected with the alternating current generator via a circuit which will switch on rechargeable battery to supply electricity to the electronic meter when the alternating current generator does not provide sufficient power and will switch off the rechargeable battery and make the alternating current generator charge the rechargeable battery during the time when the alternating current generator produces sufficient working power for the electronic meters. <IMAGE>

Description

  • 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 alternating 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 inconvenience in operation.
  • EP-A-0'174'747 shows an exercise bicycle with a flywheel and dynamotor set containing a generator. The flywheel is used as damping element and consists of a wheel having an outer cylindrical contact surface where a drag strag is wrapped around. A coil spring maintains the tension of the drag strag. When a person rotates the pedals, the flywheel rotates subject to frictional resistance created by the contact between the drag strap and the surface of the flywheel, so that the person using the bicycle has to overcome this additional resistance. The resistance is/can be varied by the tension of the spring.
    The dynamotor set is used to produce electric power and is connected to a battery. It is coupled to the flywheel in the common way.
  • US-A-4'298'893 shows an exercise bicycle with a front wheel having a usual rubber tire and a generator pressed against this tire by a spring. The bycicle is used to charge a battery which in turn operates a television set or the generator can be used to operate the television set directly.
  • WO 94/22538 shows a motor 110, consisting of a rotatable cylindrical shell 111, magnets 113 secured to this shell and stators 116 secured to a fixed shaft 118. The aim of this motor is to replace the flywheel known in the prior art, which rotates subject to drag resistance and are especially known by EP-A-0'174'747 and to dissipate the energy generated by the exercise movement.
  • 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 the features, set out in claim 1, of construction, combination of elements and arrangement of parts which will be exemplified in the construction hereinafter disclosed.
    • FIG. 1 is a perspective view of the present invention;
    • FIG. 2 is a sectional view of the present invention;
    • FIG. 3 is a side view of the present invention;
    • FIG. 4 is an enlarged view of the alternating current generator;
    • FIG. 5 is a generalized block diagram of the present invention.
  • 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 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 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 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. Accordingly, the user may set and/or adjust the electronic meter whenever he likes thereby making it very convenient in use.
