Abstract: An amplitude change-over device for a body vibration machine includes two eccentric units respectively fixed on the opposite ends of a rotating shaft driven by a motor. Each eccentric unit contains an eccentric driving plate secured with the rotating shaft for rotating together and an eccentric driven plate movably fitted on the rotating shaft at one side of the driving plate. Either one of the driving plate or the driven plate has a surface bored with a slide groove with the rotating shaft acting as a pivot, and another one has a surface provided with a projecting stud inserted in the slide groove. The motor is a right-handed and left-handed one. When the motor is chosen to rotate clockwise or counterclockwise, the included angle of the driving plate and the driven plate is changeable and hence amplitude power is adjustable by using a single motor.

Abstract: A vibrating mechanism of a body vibration machine includes a step, a bottom board and a driving mechanism that has upper linking bars and lower linking bars connected with the step and the bottom board, and plural direction-restricting sets installed between the step and the bottom board. Each position-restricting set has a cylinder and a guiding bar inserted in the cylinder to enable the step moved vertically. A crank is connected with the upper linking bar and the lower linking bar via a pivotal shaft so that it can spontaneously drive the pivotal shaft to move circularly, enabling the step to move vertically. Moreover, a small motor is powerful enough as the step is driven to move by the upper and the lower linking bar instead of the driving motor directly.

Abstract: A rotary wheel with a rowed-lights displaying device includes a rotary wheel, a set of rowed-lights, a detecting member and a controller. The set of rowed-lights set on the rotary wheel is provided with a row of lights controlled by the controller to turn on once while rotating for a preset angle along with the rotary wheel. The detecting member can detect the rotation speed of the rotary wheel and transmit the value of the speed to the controller that is able to calculate the time needed for the rotary wheel to rotate a preset angle to enable each light of the rowed-lights to precisely turn on/off as set up previously. Via the photogene theory, a person's eyes can see a complete message designed in advance by means of the lit rowed-rights on the rotary wheel.

Abstract: A control device for a jogging machine includes a stepping board, and a plurality of non-touch sensors arranged in line spaced apart equidistantly on two sides of the stepping board for sensing the position of the two feet of a user dropping on the stepping board for a controller to figure out the speed of the user and then adjust the speed of a moving band moving on and below the stepping board. The control device automatically adjusts the speed of the moving band to suit to the speed of the user's feet. Further, the control device has two angle adjusting sensors respectively fixed on two sides of a handle for adjusting the inclining angle of the stepping board by the user extending a hand nearer to either of the two adjusting sensors.

Abstract: A device for displaying the exercise information of a sports apparatus includes a RS-232 transmission line connected with a micro-processor unit (MPU) that is connected with a monitor menu controller, which is provided for modulating the brightness, the contrast ratio and the vertical and horizontal location displayed on a monitor. The MPU transmits the RS-232 instruction between a sports apparatus and the monitor menu controller and also transmits signals to a microprocessor in the interior of the monitor. The signal put in order by the video controller is transmitted to the monitor menu controller that carries out two-way communication with a video modulator of a monitor. Thus the exercise information produced by an exerciser on a sports apparatus can be displayed on the monitor.

Abstract: A walk simulating machine includes two pedal connect rods, a horizontal rod, two side connect rods consisting of an upper and a lower connect rod, and a stop member in front of each upper connect rod. The lower connect rods sway together with the pedal connect rods. The upper and the lower connect rods sway straight if the upper connect rods not stopped by the stop member; the lower connect rods solely sway if the upper connect rods stopped. So the walking orbit of the pedals may have different centers in the two different conditions. The front end portion of the walking orbit bends up, letting the heels land on the ground first for a user to stand stably. Further, a slope adjuster is provided to adjust the angle of the stop members relative to the upper connect rods for making three modes of exercise.

Abstract: A walk simulating machine is provided with two side connecting rods for supporting two pedal connecting rods. Each side connecting rod consists of an upper and a lower connecting rod pivotally connected with each other, the upper connecting rod fixed with a horizontal rod, while the lower connecting rod able to sway back and forth together with the pedal connecting rod. Thus, when the upper and the lower connecting rod are positioned in a straight line and in a non-straight line, the sway pivot of the front end of the pedal connecting rod will be different and hence the front end of the walking orbit will turn upward a bit, able to keep a user's body stable when exercising walk thereon. The upper connect rods can be driven by a slope adjuster to change its positional angles and synchronously change the angles of the walking orbit.
