摘要： A motorized treadmill includes a base, an endless belt movable relative to the base for allowing a user to exercise thereon, a motor coupled to the endless belt for driving the endless belt to rotate, a current sensor coupled to the motor, and a controller in communication with the motor and the current sensor. The current sensor is configured to detect a motor current of the motor when using the motorized treadmill. The controller is configured to analyze fluctuations of the motor current to determine whether objects or children interfere with rotation of the endless belt. When the current sensor detects a current change not associated with the user of the motorized treadmill, the controller determines that the endless belt is interfered by objects or children and stops operation of the motor to slow or stop rotation of the endless belt.

摘要： A stationary exercise apparatus includes two connecting members each having an upper end guided to move along a circular path and a lower end coupled to a swing member, so that when the upper end moves along the circular path, the lower end moves along an arc-shaped path. Two supporting members are configured to support a user's feet, which are coupled between the upper end and the lower end of the respective connecting members and movable along a closed path. Two control members each is arranged between the corresponding supporting member and the corresponding swing member for guiding the second portion of the corresponding supporting member along a predetermined path, so that an angle formed between each supporting member and the corresponding connecting member varies as the corresponding swing member moves along the arc-shaped path between a first endpoint and a second endpoint.

摘要： The present disclosure regards a manual treadmill. The manual treadmill includes a continuous belt coupled to a frame and adapted for an operator walking or running thereon; a sensing apparatus, sensing a parameter and producing a corresponding speed signal corresponding to a current rotating speed of the continuous belt; an inputting apparatus, producing an indication signal corresponding to a target rotating speed of the continuous belt; a control unit, receiving the corresponding speed signal to get a current speed value, receiving the indication signal to get a target speed value, and producing a first control signal; and a resistance adjusting apparatus, producing a resistance to impede the rotation of the continuous belt; wherein the control unit controls the resistance adjusting apparatus using the first control signal to decrease (or increase) the resistance when the current speed value is lower (or higher) than the target speed value.

摘要： The present invention provides an exercise apparatus for allowing a user to perform an exercise. The user drives at least one moving member to rotate a flywheel. The flywheel must overcome a resistance generated by a magnetic field generating module during rotation. In a preferred embodiment, the magnetic field generating module is supported by a flexible support member and tends to restore to an initial position. The magnetic field generating module will be pushed by the flywheel in a rotational direction of the flywheel and to generate a corresponding displacement. The displacement or the deformation of the support member is measured by a first measuring device so as to appropriately calculate the output force of the user, and further obtains power, metabolic equivalent or calorie consumption rate if correlated with rotational speed of the flywheel or corresponding parameters measuring by a second measuring device.

A predetermined portion oriented between the top and bottom ends of each linkage is pivotally coupled to the corresponding crank unit and is moved along a circular path. The top end of each linkage is pivotally coupled to the corresponding reciprocating member and is moved along a curved path between two retracing points. The front end of each carrying arm is pivotally coupled to the bottom end of the corresponding linkage and is moved along a first closed path which is elliptical-like shaped. A predetermined portion oriented between the front and rear ends of each carrying arm is pivotally coupled to the bottom of the corresponding swing arm. The rear end of the carrying arm supports user's foot and is moved along a second closed path.

摘要： The present invention relates to an exercise apparatus with an adjustable resistance assembly. The adjustable resistance assembly has a screw portion. An user can rotate an operating portion which is connected to one end of the screw portion to move the screw portion to drive a pushing portion toward a rotating member which is pivotally connected on the exercise apparatus. Simultaneously, the pushing portion drives an elastic member to cause deformation and make a friction surface of a resistance member which is connected on the elastic member gradually press the rotating member therefore increases friction resistance. When the user rotates the operating portion reversely, the screw portion is moved outward the rotating member and the elastic member recovered from the deformation thereby decreases the friction resistance relative to the rotating member.
