20100222182 | TREADMILL WITH AUTOMATIC SPEED CONTROL AND CONTROL MODULE OF THE SAME - A treadmill includes a body having a belt for supporting an exerciser, an exerciser detecting portion installed in a predetermined area of the body to detect movement of the exerciser, a driving motor coupled to the body to drive the belt, a control portion for generating a first control signal for adjusting a rotation speed of the driving motor based on a signal received from the exerciser detecting portion, a motor driving portion for adjusting the rotation speed of the driving motor according to the first control signal received from the control portion, and an electrical braking portion for reducing the rotation speed of the driving motor. The treadmill quickly follows acceleration or deceleration of an exerciser; provides an experience as if the exerciser is exercising on the ground, thereby improve an exerciser's exercising experience; accepts various exercising patterns of an exerciser; resolves a problem in that a motor driving portion is tripped due to a load caused by quick deceleration; and preprocesses measured values of an exerciser's position to resolve a problem in that a speed of a belt cannot be controlled due to measurement errors contained in measured values. | 09-02-2010 |
20100210419 | TREADMILL WITH AUTOMATIC SPEED CONTROL, CONTROL MODULE OF THE SAME AND CONTROL METHOD OF THE SAME - The present invention provides a treadmill with an automatic speed control function, including: a body having a belt for supporting an exerciser; an exerciser detecting portion installed in a predetermined area of the body to detect movement of the exerciser; a driving motor coupled to the body to drive the belt; a control portion for generating a control signal for adjusting a rotation speed of the driving motor based on a signal received from the exerciser detecting portion; and a motor driving portion for adjusting the rotation speed of the driving motor according to the control signal received from the control portion, wherein a provision braking torque provided corresponding to the control signal is varied as the rotation speed of the driving motor is reduced. The treadmill quickly follows acceleration or deceleration of an exerciser, realizes a feeling like what an exerciser has while exercising on the ground to thereby improve an exerciser's exercising feeling, accepts various exercising patterns of an exerciser, resolves a problem in that a motor driving portion is tripped due to a load caused by quick deceleration, and pre-processes measured values of an exerciser's position to resolve a problem in that a speed of a belt can not be controlled due to measurement errors contained in measured values. | 08-19-2010 |
20100210418 | TREADMILL, FITNESS DEVICE, CONTROL METHOD OF THE SAME, AND CONTROL MODULE OF THE SAME - A fitness apparatus includes: a body having a belt for supporting an exerciser; a driving motor for driving the belt; a motor driving portion for driving the driving motor; a display device installed in a predetermined area of the body to provide information to the exerciser; and a control portion for determining symbol display coordinates using an exerciser speed corresponding to a rotation speed of the driving motor, and outputting a symbol corresponding to the exerciser at the symbol display coordinates through the display device. According to the fitness apparatus of the present invention, an exerciser can control the symbol display coordinates of a symbol displayed on the display device, and thus various game functions can be implemented. Therefore, an exerciser can enjoy an exercise without easily feeling tedious. | 08-19-2010 |
