The rotating mechanism assembly includes two cranks coaxially pivoted with one ends thereof to the base frame, and a support link set pivotally coupled between the other ends of the cranks and slidably coupled to the sliding rails. The control mechanism is mounted between the base frame and the rail holder to control the angle of deflection of the lifting mechanism. The sliding mechanism is pivotally coupled between the control mechanism and the rail holder. Thus, the invention allows quick adjustment of the pedal motion paths, training different muscles of the legs.

    Abstract: A workout device with a foot-oriented elliptical loop is provided and bilaterally equipped with a transmission rod, a first link rod, a driving rod, a second link rod, a swing arm, and a supporting rod. The transmission portions are pivotally coupled to cranks to enable the cranks to undergo revolution. The supporting rods each have a supporting portion to support a user's feet. The aforesaid rods interact with each other. The supporting portions of the supporting rods move along a closed elliptical loop with segmental junctions spaced apart by a relatively short distance, such that the user's treading process is prevented from undergoing abrupt descents, un smooth transitions, and thus jolts.

  • Publication number: 20140187387
    Abstract: The present invention relates to a stair exercise device for simulating stair climbing, the device having a plurality of steps which are activated by the weight of a person walking up them. A stationary platform at the base of the stair exercise device sends a signal to a controller to bring the exercise device to a controlled stop when an operator steps onto the platform. The steps of the exercise device stop in a predetermined location when the exercise device comes to a controlled stop, ensuring proper step location to allow the operator to easily enter and exit the exercise device. Steps have a step platform of a different color than the risers between steps to aid in foot placement.

    Abstract: A method and/or a device may limit a distance traveled by a treadle assembly in an exercise device. For example, the distance traveled by the treadle assembly may be limited by limiting a distance that a resistance element operably coupled to the treadle assembly may travel. An exercise apparatus may include a travel-limiting device or capability.

  • Patent number: 8753252
    Abstract: An exercise apparatus includes a substantially flat, rigid platform for supporting a user during exercise. An inflatable tubular support having an upper portion with a first radial outside diameter, and a lower portion with a second radial outside diameter that is greater than the first radial outside diameter, is coupled to the platform by a fastener. The tubular support defines a central opening that communicates between the platform and a support surface. The platform includes a venting structure for releasing air from the central opening during use. The inflatable support includes an intermediate portion between the upper portion and the lower portion of the tubular support, the intermediate portion including a support feature to restrain the intermediate portion from radial expansion induced by an air pressure internal to the integral inflatable support.

  • Patent number: 8740754
    Abstract: An adaptive exercise device provides for a foot motion in which the vertical component of the path of foot travel is mechanically decoupled from the fore-aft component of the path of foot travel so that a user may selectably control the ratio of these two components during the use of the device. The adaptive exercise device includes foot links which are supported on a track for motion therealong. The links are mechanically interconnected so that when a first link moves in a first direction along the track, the second link moves in an equal and opposite direction. The apparatus further includes a vertical motion control system which raises and lowers portions of each of the foot links along a vertical path of travel independent of their position along the track.

    Abstract: The present invention relates to a standup exercise apparatus that simulates walking and jogging with arm exercise. More particularly, the present invention relates to an exercise machine having separately supported pedals for the feet and arm exercise coordinated with the motion of the feet where the pedal stride length is determined by the movements of an operator. Crank arms are positioned on the framework forward the operator at a height comparable to the pedals. Compound guides are used to achieve elliptical curve pedal paths.

  • Patent number: 8734300
    Abstract: An exercise device employing side-by-side pivotally supported moving surfaces. In one particular example, an exercise device employs a first belt deployed about a front roller and a rear roller and an adjacent second belt deployed about a front roller and a rear roller. The rear of the belts in the area of the rear rollers are pivotally secured and the front of the belts in the area of the front roller are adapted to reciprocate in an up and down motion during use. In some implementations, the moving surfaces include an interconnection structure such that a generally downward movement of one surface is coordinated with a generally upward movement of the other surface. In other implementations, the moving surfaces are operably associated with one or more resistance elements that effect the amount of force required to pivot or actuate the moving surfaces.
