ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a work-indicating unit of a magnetic control exercise apparatus, and more particularly, to indicators powered by the voltage produced during the motion of the exercise apparatus. In cooperation with a circuit board and sensing elements, the light-emitting elements are controlled and turned on or off.
2. Description of the Prior Art
A magnetic control exercise apparatus is an exercise apparatus (e.g. exercise bike, rowing exercise apparatus, treadmill, etc.) which makes use of the magnetic resistance elements in cooperation of the rotation of the flywheel to control the exercise resistance. In operation, when the pedals
11
are treaded, the pedal wheel
12
is rotated to bring a chain wheel
14
in motion by means of a chain
13
. A unidirectionally driven flywheel
16
is coaxially fitted beside the chain wheel
14
on axle
15
. Accordingly, the flywheel
16
rotates with the chain wheel
14
due to the coaxial arrangement. Thereafter, the flywheel
16
has an adjustable magnetic resistance element
18
with magnet sets
17
. A proper resistance is created by adjusting the clearance between the magnetic resistance elements
18
and the flywheel
16
. At the same rotational speed, increasing the clearance between the flywheel and the magnetic resistance elements reduces the exercise resistance (amount of exercise or work).
The conventional product to indicate the amount of exercise is fitted with a, detecting device (not shown). After receipt of a value of amount of exercise (or the voltage value created between the flywheel
16
and the magnet sets
17
), the value will be transmitted through wiring to the microprocessor (not shown) of a control panel
19
. Then, the value will be converted by the built-in program into the Watt value to show on the control panel
19
. However, the Watt value is a professional term that offers normal operators a “value” without significance. Moreover, the trainers in gyms have to look at the console to learn the amount of exercise. It's unpractical for trainers and trainees.
SUMMARY OF THE INVENTION
It is a primary object of the present invention to remove the above-mentioned drawbacks and to provide a work-indicating unit for a magnetic control exercise apparatus in which the voltage created during the exercise session is used to actuate the light-emitting elements such that lights are turned on or off to indicate the work or amount of exercise being performed in unit time and display the information.
