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.

In one embodiment, an adjustable surface stiffness treadmill includes a treadmill unit, a scissor mechanism that supports the treadmill unit, a stiffness adjustment mechanism configured to adjust a vertical stiffness of the treadmill unit, and an input link having a first end and a second end, the first end being connected to the scissor mechanism and the second end being connected to the stiffness adjustment mechanism, wherein the input link translates downward vertical forces imposed upon the treadmill unit into horizontal forces imposed upon the stiffness adjustment mechanism.

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 treadmill includes a frame, a tread assembly and two cushion assemblies. Each of the cushion assemblies includes a supporting element and at least one buffering element. An upper portion of the tread assembly is supported on the supporting element. The buffering element is provided between the supporting element and the frame.

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.

The invention provides a shock absorption mechanism for a treadmill. The shock absorption mechanism for a treadmill consists of a running platform, a base and rubber columns connecting the running platform and the base, wherein opposing magnets are respectively fixed below middle parts of two sides of the running platform and above middle parts of two sides of the base, and the magnets on the running platform and the magnets on the base have the same magnetic pole, thus forming a repulsive force for shock absorption. Such shock absorption mechanism has the advantages of no noise, a long service life, good comfort and the like when in use.

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 frame having a front end and a rear end, substantially opposite the front end; a front shaft assembly coupled to the frame proximate the front end of the frame; a rear shaft assembly coupled to the frame proximate the rear end of the frame; a running belt disposed about the front and rear shaft assemblies; and a bumper coupled to the frame proximate the running belt such that the bumper is disposed between the running belt and the frame. In use, the bumper is configured to selectively restrict movement of the running belt towards at least a portion of the frame.

In one embodiment, an adjustable surface stiffness treadmill includes a treadmill unit, a scissor mechanism that supports the treadmill unit, a stiffness adjustment mechanism configured to adjust a vertical stiffness of the treadmill unit, and an input link having a first end and a second end, the first end being connected to the scissor mechanism and the second end being connected to the stiffness adjustment mechanism, wherein the input link translates downward vertical forces imposed upon the treadmill unit into horizontal forces imposed upon the stiffness adjustment mechanism.
