Manual treadmill which can be set to an exercise speed

A non-powered treadmill which is driven by movement of a user, the non-powered treadmill comprising:

• a frame having a fixed portion and a mobile portion, an elevation angle of the mobile portion being adjustable with respect to the fixed portion;
• a continuous belt mounted around the mobile portion, having a top surface that is movable with respect to the mobile portion for allowing the user to perform walking, jogging or running thereon;
• a sensor configured to detect a rotation speed of the continuous belt;
• and
• a control unit configured to control a resistance of the continuous belt and the elevation angle of the mobile portion of the frame for adjusting the rotation speed of the continuous belt;
• wherein when the rotation speed of the continuous belt is slower than a predetermined speed, the control unit is operable to decrease the resistance of the continuous belt;
• when the rotation speed of the continuous belt is faster than the predetermined speed, the control unit is operable to increase the resistance of the continuous belt;
• and wherein when the rotation speed of the continuous belt is slower than the predetermined speed and when the resistance of the continuous belt has reached a lower limit of available resistance settings, the control unit is operable to increase the elevation angle of the mobile portion to further increase the rotation speed of the continuous belt.

A method for controlling a rotation speed of a continuous belt of a non-powered treadmill which is driven by movement of a user, the method comprising:

• receiving a target rotation speed inputted by the user;
• detecting the rotation speed of the continuous belt by a sensor;
• applying a resistance to impede rotation of the continuous belt;
• decreasing the resistance applied to the continuous belt if the rotation speed of the continuous belt is slower than the target rotation speed;
• increasing the resistance applied to the continuous belt if the rotation speed of the continuous belt is faster than the target rotation speed;
• and
• increasing an elevation angle of the continuous belt if the rotation speed of the continuous belt is slower than the target rotation speed and when the resistance has reached the lower limit of available resistance settings.
