A portable, foldable, and manually-powered exercise apparatus including a frame having first rails and second rails. First and second rails receive a first walking surface and second walking surface, respectively. The exercise apparatus includes hinge plates connecting first and second rails and include first legs. The exercise apparatus includes second legs connecting the first rails and support and place first rails at an inclination angle. The exercise apparatus includes first rollers connecting the first rails, and second roller connecting the second rails. The first rollers and second roller receive a tread belt over the first walking surface and second walking surface. User walks/runs on the tread belt causing first rollers and second roller to rotate. The second legs fold, and the hinge plates allow folding of second rails along with the second walking surface underneath the first rails and first walking surface without the first rollers coming into contact with the second roller.

A treadmill has a front or rear set of pulleys and a looped running belt. The pulleys rotate with the movement of the belt, e.g., when a user walks, jogs, or runs on the treadmill. The pulleys are mounted on a rotating roller tube so that the roller tube rotates with the pulleys. The roller tube is mounted on a stationary shaft using bearings on each side and a one-way device that allows the pulleys to rotate in one direction. The rotation direction corresponds to the movement of the top of the belt from the front to the rear of the treadmill. The one-way device prevents the pulleys from rotating in the opposite direction, preventing the top of the belt from moving from the rear of the treadmill to the front. The one-way device may be a sprag clutch. The treadmill may be a motor-less, curved treadmill.

An omnidirectional treadmill platform includes a splicing floor, an omnidirectional driving base and a floor removing/splicing actuator. A plurality of omnidirectional wheels are arranged in the driving base. The splicing floor is placed on the omnidirectional wheels. A user moves on the splicing floor, and the omnidirectional wheels of the driving base cause the splicing floor to move in a direction Opposite to the movement direction of the user thus enabling the user to experience unlimited free movement, while in reality remaining in place. The splicing floor is formed by splicing a plurality of splicing blocks. The floor removing/splicing actuator removes and splices the splicing blocks at right positions, recycling splicing blocks and achieving the unlimited extension of the splicing floor. The new platform provides unrestricted movement and variable ground surface simulation irrespective of turn radius with near-negligible inertia force without the use of special footwear.

A treadmill includes a frame; a running belt configured to move relative the frame; and a motor coupled to the running belt. The motor is operable in a plurality of user controlled operating modes. In a first operating mode, the force of rotation of the running belt is provided by a user of the treadmill. In a second operating mode, the motor applies a desired braking force to resist rotation of the running belt. In a third operating mode, the motor applies a torque output to the running belt based on a force exerted on the running belt by a user of the treadmill.

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.

Provided is a treadmill. The treadmill includes a first frame and a second frame, a front roller and a rear roller respectively provided in the first frame and the second frame and a plurality of slats extending perpendicularly to a direction in which the first frame and the second frame are located. The slats are located between the first frame and the second frame and installed movably with respect to the first frame and the second frame. Some of the plurality of slats include a base portion providing a first surface and a strength reinforcing portion protruding from the base portion. The strength reinforcing portion includes a first reinforcing portion protruding from the base portion and a second reinforcing portion extending in a direction intersecting a protrusion direction of the first reinforcing portion, the second reinforcing portion provides a second surface.

An omnidirectional treadmill platform includes a splicing floor, an omnidirectional driving base and a floor removing/splicing actuator. A plurality of omnidirectional wheels are arranged in the driving base. The splicing floor is placed on the omnidirectional wheels. A user moves on the splicing floor, and the omnidirectional wheels of the driving base cause the splicing floor to move in a direction opposite to the movement direction of the user thus enabling the user to experience unlimited free movement, while in reality remaining in place. The splicing floor is formed by splicing a plurality of splicing blocks. The floor removing/splicing actuator removes and splices the splicing blocks at right positions, recycling splicing blocks and achieving the unlimited extension of the splicing floor. The new platform provides unrestricted movement and variable ground surface simulation irrespective of turn radius with near-negligible inertia force without the use of special footwear.
