The invention belongs to the technical field of fitness equipment, in particular to the independent suspension vibration damping mechanism of running platform of a treadmill. It solves the problem that the shock effect of the existing treadmill is poor and so on. It includes the chassis and the runway frame. The front end of mentioned runway frame is suspended on the chassis by means of a suspension structure and when the runway frame is subjected to a downward force and forcing the front end of the runway frame to descend, the suspension structure can assist the front end of the runway frame to rise and reset. The independent suspension vibration damping mechanism of running platform of the treadmill has the advantages: simple structure, good stability, good shock absorption effect, providing shock absorption buffer to multiple locations of the treadmill, long span life, and high mechanical strength.

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 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 includes a base that extends in a length direction, a width direction, and a height direction that are perpendicular to each other. A mobile portion is configured to support the user during operation of the fitness machine. A resilient body is configured to provide a resistance against the mobile portion moving towards the base in the height direction. A frame is moveable in the length direction relative to the base to adjust the resistance provided by the resilient body. A fastener assembly moveably couples the frame to the base, where the fastener assembly is configured to expand in the width direction to prevent the frame from moving in the width direction relative to the base during operation of the fitness machine.

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 treadmill includes a frame, an endless belt, and a motor assembly for guiding the belt between front and rear ends of the frame while a user walks or runs on the belt. An impact absorbing assembly is supported beneath a region of the treadmill belt impacted by the user's feet when the user walks or runs on the belt. The assembly has physical properties that serve to define degrees of damping or springiness of the belt in the region impacted by the user. A control system including a user interface is coupled to the absorbing assembly, and the system is configured and operative to vary the physical properties of the assembly in response to an output from the user interface. The region of treadmill belt impacted by the user's feet then simulates a desired one of a number of different surfaces entered by the user on the interface.

A treadmill includes a deck, a first pulley disposed in a first portion of the deck, a second pulley disposed in a second portion of the deck, a tread belt surrounding the first pulley and the second pulley, and a platform incorporated into the deck.

The present invention relates to an apparatus (100, 1001, 1002) for physical activity, comprising: a frame (101); a plurality of rollers (203, 204) rotatably connected to the frame (101); a belt (200) mounted on the plurality of rollers (203, 204) and revolving to define moving belt surfaces (201, 202) comprising: an activity belt surface (201) being configured for physical activity of at least one user (301, 701) and delimited by a side of the frame (101), and a return belt surface (202) being configured for revolving the belt (200) in a never-ending loop; the return belt surface (202) is elevated with respect to the activity belt surface (201).

Treadmill configured to automatically determine user exercise movement. In some embodiments, a treadmill may include a deck, a first pulley disposed in the deck, a second pulley disposed in the deck, a tread belt surrounding the first pulley and the second pulley, an electronic sensor incorporated into the treadmill and configured to automatically produce measurement data in response to exercise movement performed by a user over the deck, an electronic console including an electronic display, a processor, and a memory. The memory may include programmed instructions that, when executed, cause the processor to automatically analyze the measurement data produced by the electronic sensor to automatically determine a characteristic of the exercise movement performed by the user over the deck, and automatically present, on the electronic display, an indication of the characteristic of the exercise movement performed by the user over the deck.
