  • Patent number: 10105568
    Abstract: Stair climber apparatuses have a control circuit that controls the speed and torque of an electric motor and controls an output torque direction of the electric motor. The control circuit controls the speed of the electric motor and the output direction of the electric motor to maintain a constant speed of travel of a plurality of stairs in a downward direction along an inclined support when an operator is stepping on the plurality of stairs in an upward direction. When a change in output torque direction of the electric motor torque is required to maintain the constant speed of travel of the plurality of stairs in the downward direction along the inclined support, the control circuit controls the speed of the electric motor down to a zero speed. Methods are for operating the stair climber apparatuses.

  • Patent number: 9272181
    Abstract: An exercise apparatus comprises a frame, a left foot link supporting a left foot pad, a right foot link supporting a right foot pad in a left foot link supporting a left foot pad. The right foot pad is linked to the left foot pad so as to synchronously move out of phase with the left foot pad through an elliptical path having an adjustable step height and an adjustable stride length. An adjustment synchronizer is operably coupled to the left foot link and the right foot link to synchronously adjust both the step height and the stride length of the elliptical path.

  • Patent number: 9272182
    Abstract: An exercise device providing a fore and aft horizontal component of striding motion that is dynamically user-defined, while providing a vertical component of the motion that is maintained on a predetermined vertically reciprocating path in some embodiments. The exercise device guides the user's foot in a pseudo-elliptical stride path, while providing a dynamically variable stride length that allows the user to move with a natural stride length. The exercise device allows tall and short users to extend or curtail the stride length to match their natural stride lengths. The length of the reciprocating path is dynamically adjusted during the exercise operation without equipment adjustments by changes in the length of the stride input by the user at a pair of foot engagement pads disposed on laterally spaced apart foot support members.

  • Patent number: 9259610
    Abstract: An exercise device comprises a frame, a rotational mechanism, a left and a right coupling mechanism, and an adjusting assembly. A post structure is upwardly extended from the front portion of the frame. The rotational mechanism is arranged at the post structure. The left and right coupling mechanisms are arranged at a side of the post, respectively. One end of the left and right coupling mechanism couples to the rotational mechanism, and the other end respectively comprise a left and a right pedal assembly making a moving path. The adjusting assembly comprises a left and a right linkage structures with two ends, in which one end couples to the post and the other end moveably couples to the left and right pedal assembly. By changing the angles between the left and right linkage structures and the post structure, the pedal assemblies are moved to determine a step distance.

  • Patent number: 9254409
    Abstract: Embodiments of a strength training apparatus and related methods are provided. In one embodiment, the strength training apparatus includes a base member and a tower structure coupled with the base member. At least one arm is pivotally coupled with the tower structure. A flywheel and a cable and pulley system are associated with the at least one arm, wherein displacement of at least one cable of the cable and pulley system effects rotation of the flywheel. The strength training apparatus may include a selectively adjustable magnetic braking mechanism associated with a flywheel that is configured to apply a selected resistance to the rotation of the flywheel. A torque sensor may be associated with the flywheel and the measured torque during operation of the apparatus may be used to calculate the work expended in rotating the flywheel. In one embodiment, the calculated work may be expressed in units of watts.

  • Patent number: 9162105
    Abstract: A fitness apparatus includes a chassis, two linkages, two handlebars, two cranks and two joint bars. Each of the linkage includes a first linking-up part and second linking-up part transversally. The first linking-up parts are pivotably attached to the cranks for revolution of the cranks relatively to the chassis. Each of the handlebars includes a lower portion pivotably attached to the second linking-up portion, and an upper portion which can be held by the user to move along a closed elliptical trajectory. Each of the joint bars includes a rear and portion pivotably attached between the upper portions and the lower portions, and a front end portion pivotably attached to the chassis. In this way, the user's arms can take exercise effectively along an elliptical trajectory to further prevent the user from suffering sports injury resulting from incorrect posture.
