Shaking endless belt for treadmills
A treadmill includes a frame having two rollers and an endless belt is mounted on the two rollers. One of the rollers is driven by a motor and a control device is electrically connected to the motor so as to control the motor to be rotated in different directions alternatively. The alternative rotation of the motor shakes the endless belt and the user's body.
The present invention relates to a treadmill which includes a control device for changing the operation modes of the motor so as to cause shaking to the endless belt so that the user on the endless belt is massaged by the shaking.
BACKGROUND OF THE INVENTION A conventional treadmill 50 is shown in
The present invention intends to provide a treadmill with a control device which controls the motor to rotate in different directions periodically so as to cause the endless belt to shake while the user is running on the endless belt. The shaking of the endless belt exercises the user's whole body.
SUMMARY OF THE INVENTIONThe present invention relates to a treadmill which comprises a frame having two rollers installed at two ends of the frame and an endless belt is mounted on the two rollers. One of the rollers is driven by a motor with a transmission belt connected therebetween. A control device is electrically connected to the motor and controls the motor to rotate in different directions alternatively.
The primary object of the present invention is to provide a treadmill wherein the endless belt shakes by the alternative rotation of the motor so that the users on the endless belt have extra exercise to their bodies. The angles that the motor rotates can be controlled by the control device so as to meet different requirements.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring to FIGS. 1 to 3, the treadmill 10 of the present invention comprises a frame having two rollers 11 installed at two ends of the frame and an endless belt 12 is mounted on the two rollers 11. One of the rollers 11 is driven by a motor 20 with a transmission belt 21 connected therebetween. A control device 30 is electrically connected to the motor 20 and controls the motor 20 to rotate in different directions alternatively. The control device 30 can be electrically connected with a control panel (not shown) on a handle bar (not shown) of the treadmill 10. As shown in
As shown in
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
