Abstract

PURPOSE:To provide a device serving double purposes of enhancing the physical fitness of the user and charging the battery performed by a mechanism structured as an electric power generator built in a box body where a stator is fixed and a rotor is fixed to a rotation axis and installed in such a way that the inner circumference of the rotor magnet faces the external circumference of the stator coil with a predetermined gap in between them. CONSTITUTION:A legless chair and a handle are fixed on the upper surface of a box body 1, and a rotation axis 4 is strutted horizontally by a bearing 5 on both sides of the box body 1. Arms 6, 6 are fixed to the edges protruding from both sides of the box body 1, and pedals 7,7 are fixed to the tips of the said arms in a way freely rotatable. Thus, as a user sits on the chair with his hands on the handle and steps on the pedals 7, 7 with his feet thereby rotating the rotation axis 4 adequately loaded by a flywheel 12, he can obtain an enhancement of his physical fitness which was wanting due to underexercise. Furthermore, as a rotar 11 revolves along with the rotation of the rotation axis 4 making the magnetic flux from magnets 13, 13 run through coils 9, 9, an alternating current is generated to the coil. The alternating current is rectified and used to charge the battery.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generator-equipped bicycle-type footstep device for rotating a rotor of a generator to generate electricity by operating a pedal of a bicycle for health.

[0002]

2. Description of the Related Art A bicycle-type footstep device in which a pedal is attached to a rotary shaft projecting from both sides of a seat and a housing with a handle, a predetermined load is applied to the rotary shaft, and the pedal is stepped on to enhance physical strength. Is known. Further, a manual power supply device in which a rotor of a generator is manually rotated to generate electric power is also known.

[0003]

DISCLOSURE OF THE INVENTION In the above prior art,
The former cannot use the energy effectively by simply stepping on the pedal, and since the cord must be plugged into the electrical outlet to operate an electrical accessory such as a pedal speed meter, it cannot be used outdoors and the place of use is restricted. In the latter case, since the rotor is manually rotated to generate electric power, the battery as a power supply device needs a monotonous manual operation for a considerably long time.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and a rotary shaft is horizontally arranged in a housing with a seat and a handle, and the rotary shaft protrudes from both sides of the housing. In a bicycle-type foot-operated device in which a foot-rotating member is attached to the housing, the stator of the generator is fixed to the housing, the rotor is integrally attached to the rotating shaft, and the inner peripheral surface of the magnet of the rotor is attached to the outer peripheral surface of the stator coil with a predetermined gap. It is characterized in that they are opposed to each other and constitute a generator.

1 and 2 show a first embodiment of the present invention. 1
Is a box-shaped case having a chair 2 and a handle 3 fixed to the upper surface thereof. Reference numeral 4 denotes a rotation shaft, which is horizontally supported by bearings 5 on both sides of the housing 1 and has arms 6 and 6 fixed to ends projecting from both sides of the housing 1, and pedals 7 and 7 rotatably attached to the ends thereof. There is. Support members 8, 8 are fixed to the inner surfaces of both side walls of the housing 1, and stators 10 and 10 of a generator having annular coils 9 and 9
Is fixed at a predetermined interval. Reference numeral 11 denotes a rotor fixed to the central portion of the rotary shaft 4, a flywheel 12 is integrally formed on the outer periphery, and annular magnets 13 and 13 are provided on both sides of the inner surface.
2 are fixed so that the inner peripheral surfaces of the magnets 13, 13 and the outer peripheral surfaces of the coils 9, 9 face each other with a slight gap. 14 is a battery, 15 is a handle 3
It is an instrument panel having various indicators such as pedal speed attached to the.

In use, as shown in FIG. 1, the operator sits on the seat 2 and grasps the handle 3 with his / her hand, puts his / her feet on the pedals 7, 7, and rotates the rotary shaft 4. Since an appropriate load is applied to the rotary shaft 4 by the flywheel 12, it is useful for increasing physical strength due to lack of exercise. Further, the rotor 11 also rotates with the rotation of the rotating shaft, and the magnetic flux of the magnets 13, 13 flows in the coils 9, 9 to generate alternating current in the coils 9, 9. Since this operation is well known, detailed description is omitted. This alternating current is rectified and the battery 14 is charged. Although this embodiment includes two generators, the number of generators may be one, and three or more generators may be attached if necessary.

Industrial Applicability The present invention provides a bicycle type footstep device in which a rotary shaft is horizontally arranged in a chassis with a chair and a handle, and a rotary foot member is attached to the rotary shaft projecting from both sides of the chassis. Since the stator of the generator is fixed to the housing, the rotor is integrally attached to the rotating shaft, and the inner peripheral surface of the magnet of the rotor is opposed to the outer peripheral surface of the stator coil with a predetermined gap, the generator is configured. It is not a monotonous work such as manually stepping up and strengthening the physical strength while stepping on the bicycle at the same time, but the foot of the bicycle easily rotates the rotor of the generator to charge the battery in a short time. It can be carried out.
