A treadmill includes a treadmill frame having a front end and a rear end opposite the front end; a pulley coupled to the treadmill frame; a running belt disposed about the pulley, the running belt defining a non-planar running surface; a motion restricting element coupled to the frame and configured to limit rotation of the pulley to only one rotational direction; and a brake coupled to the running belt and adapted to selectively restrict the speed of rotation of the running belt depending upon an established limit for a speed of the running belt.

A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.

A platform for enabling omnidirectional movement of an exercising machine is disclosed. The platform may comprise a hemispherical inner body comprising a hollow cavity. The hollow cavity may be used for accommodating an exercising machine into the hollow cavity. The exercising machine may be one of a treadmill, treadclimber, and bicycle. The platform may further comprise an outer body. The outer body may be rotatably engaged with the hemispherical inner body. The rotatable engagement may allow an omnidirectional movement of the hemispherical inner body in a horizontal plane and an inclination and declination of the exercising machine. The platform further comprises a communication unit. The communication unit may be connected with the hemispherical inner body for receiving user's inputs for movement. At least one of the hemispherical inner body and the exercising machine may move based on the user's inputs for movement. The platform may also find use in virtual shopping environments to help a user in buying products.

A frame lifting mechanism includes a base, a motor, a lead screw, a sliding member, a lifting member and a supporting shaft. The motor is connected to the lead screw, and the lead screw is fastened onto a transmission tube, allowing the transmission tube to move forward and backward while being driven by the lead screw. The sliding member is installed on a sliding track arranged on the base and connected to the transmission tube, allowing the sliding base to actuate with the transmission tube synchronously. A rear end of the lifting base is pivotally attached onto the base for support, and the supporting member uses its two top and bottom ends to be pivotally attached onto the lifting member and the sliding member respectively, allowing the supporting shaft to utilize the movement of the sliding member to drive the lifting member to move upward and downward.

An elliptical machine includes: a transmission mechanism disposed a the base, one end of the lateral swing track disposed on both sides is pivoted at the base, and each lateral swing track can swing laterally; a connecting rod and a stepping mechanism are disposed on both sides of the transmission mechanism, and the front end of the front connecting rod in each mechanism is pivotally connected to the base; a front end is connected to the rear connecting rod of the front connecting rod in a universal joint type, the rear connecting rod is disposed on the corresponding track; the rear connecting rod free end part is pivoted to the pedal. When the pedal is stepped on, the front connecting rod is reciprocally extended with the transmission mechanism, and the user can freely manipulate the swing angle of the lateral swing track through the lateral force applied to the pedal.

A treadmill includes a frame; a rotatable element coupled to the frame; a running belt at least partially supported by the rotatable element; and, a first element and a second element, both of which are coupled to the running belt. The running belt includes a running surface, at least a portion of which is curved. Further, one of the first and second elements and the running belt freely rotate in a first direction of rotation relative to the frame. However, in a second direction of rotation, opposite the first direction of rotation, the one of the first and second elements is substantially prevented from rotation relative to the frame to substantially prevent or resist rotation of the running belt relative to the frame.

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.

The gait rehabilitation control system according to the present invention comprises an operation device unit for setting gait training mode of a patient and displaying gait state information of the patient; a gait device unit worn on the patient's feet so as to move along with the gait motion of the patient; and a control unit for driving the gait device unit according to the gait training mode set by the operation device unit, wherein the control unit comprises a gait pattern analysis unit for measuring reaction force between the patient's feet and the gait device unit, and analyzing the gait pattern of the patient with the data of the reaction force.
