Provided is a treadmill. The treadmill includes a shock absorbing portion configured to absorb a shock applied to a deck. The shock absorbing portion includes a second anti-vibration rubber portion having a third surface fixed to a frame and a fourth surface fixed to the deck. The third and fourth surfaces are perpendicular to a plate surface direction of the deck. The second anti-vibration rubber portion includes a first anti-vibration sub-rubber having the third surface, a second anti-vibration sub-rubber having the fourth surface, and a plate located between the first anti-vibration sub-rubber and the second anti-vibration sub-rubber. The plate located between the first anti-vibration sub-rubber and the second anti-vibration sub-rubber has a greater hardness than the first and second anti-vibration sub-rubbers.

A cordless treadmill includes a deck assembly including a frame, a belt system, an incline adjustment system, and a generator system; and a display assembly that supports an electronic display device above the deck assembly for displaying information to a user. The incline adjustment system includes a lever and a lift motor, the lever having a first end rotatably coupled to a frame of the deck assembly. The generator system includes a flywheel generator coupled to at least one of a forward or rear roller and configured to generate electricity as a result of the at least one of the forward or rear rollers rotating with respect to the frame, wherein the flywheel generator is configured to provide power to the electronic display device and the lift motor.

A treadmill including a frame, a suspension connector connected to the frame, and a flexible deck connected to the suspension connector. The flexible deck is configured to flex in response to a load applied by a user striding on the treadmill. The suspension connector includes a suspension pivot that allows rotation of the flexible deck around the suspension pivot.

A fitness machine operable by a user. The fitness machine has a base and a mobile portion that moves relative to the base during operation. A resilient body resists movement of the mobile portion towards the base in a height direction. The resilient body has a length defined in a length direction that is perpendicular to the height direction. The length of the resilient body increases when the mobile portion moves towards the base. An end stop is operable to prevent the length of the resilient body from increasing beyond a set maximum. The end stop is moveable to adjust the set maximum for the length of the resilient body, where a resistance provided by the resilient body to resist movement of the mobile portion towards the base is unaffected by moving the end stop when the length of the resilient member is less than the set maximum.

A treadmill including a frame, a suspension connector, a flexible deck, and a belt. The suspension connector is connected to the frame. The flexible deck is connected to the suspension connector. The flexible deck includes a metal panel extending substantially an entire width and length of the flexible deck. The belt is disposed on the flexible deck.

A system for adjusting a stiffness of a fitness machine operable by a user, the fitness machine having a base and a mobile portion that moves relative to the base during operation of the fitness machine. A resilient body resists movement of the mobile portion towards the base in a height direction. The resilient body has a length defined in a length direction that is perpendicular to the height direction. The length of the resilient body increases when the mobile portion moves towards the base. An actuator is operable to adjust a set maximum for which the length of the resilient body may extend during operation of the fitness machine. A resistance provided by the resilient body to resist movement of the mobile portion towards the base is unaffected by operation of the actuator when the length of the resilient body is less than the set maximum.

A curved treadmill has a frame assembly, a handrail assembly, and a belt assembly. The frame assembly has a support frame, two arced guide tracks, two cushions, multiple guide wheels, and multiple positioning wheels. Each arced guide track is concaved downward. The cushions are mounted on the arced guide tracks. The guide wheels are mounted on the support frame. The positioning wheels are mounted between two ends of the support frame. The belt assembly includes two connection belts and multiple pedals. The connection belts are wrapped around the guide wheels, and one side of each connection belt abuts the positioning wheels. The pedals are mounted on the connection belts and optionally abut the cushions. Therefore, with the cushions, impacts may be absorbed and noises may be reduced. Besides, by abutting the positioning wheels, the connection belt may not be distorted sideward, and the noises are reduced further.

A cordless treadmill including a frame, a belt system, and a drop-in cartridge is disclosed. The cartridge includes a plurality of staggered rollers configured to provide tactile feedback to the user. The frame is adapted to receive the belt system and the cartridge as they are lowered into the frame, and the frame is adapted to place the belt of the belt system into tension as the belt system is lowered into the frame. An integrated flywheel generator system provides smooth operation of the treadmill and generates electricity to power additional systems.

An exercise machine includes a frame, a movable element movably attached to the frame that is movable in the performance of an exercise, and a magnetic assembly attached to the frame. The magnetic assembly has a magnetic unit movably positioned adjacent to a non-ferromagnetic material.

This invention belongs to technical field of the treadmill, especially, it is a kind of kind of low-energy consumption high-efficient treadmill. It solved some technical issues such that the machine adopting existing technology has large noise, and the operation can consume a lot of energy and so on. The low-energy consumption high-efficient treadmill includes the treadmill rack, and the treadmill rack is set with annular running belt, one end of the treadmill rack is equipped with the rotation roller, and the other end is set with the outer rotor brushless DC motor, the rotation roller mentioned above are arranged with the outer rotor brushless DC motor in parallel, the annular running belt mentioned above is winded between rotation roller and outer rotor brushless DC motor, and outer rotor brushless DC motor can drive annular running belt mentioned above during operating. Comparing with existing technology, advantages of this invention lie in: 1. The design is more reasonable, the machine is equipped with outer rotor brushless DC motor, which can produce inertia force during rotating, such inertia force can ensure operation stability of the treadmill, secondly, it can also improve the operation efficiency, in addition, the brushless slice can also reduce operation noise of the treadmill, with strong availability. 2. The costs are low.
