    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.

  • Publication number: 20130157529
    Abstract: The present invention relates to a boat propelled by two submerged independent wings actuated by means of a step simulator mechanism that imparts an vertical alternating movement to the wings, which are articulated around a shaft located forward of the center of pressure thereof, such that the wings assume angles of inclination that generates propulsive force in the upward and downward movements. In the analogous position of a conventional bicycle, the driver actuates the footrests while seated. A handlebar, connected to a rudder, is used to maneuver the vehicle. The catamaran configuration offers hydrodynamic efficiency and stability. When disassembled, the mainframe of the boat can be converted into a step machine, simply fitting a pair of dampers to the structure, which absorb and dissipate the energy generated during exercising. Thus, the present invention has a dual use—boat and gymnastics apparatus—and can be transported in the car trunk.

  • Publication number: 20120322624
    Abstract: A sports training machine includes a frame having a first rotational axis and a second rotational axis, both ends of which are provided with a first linkage and a second linkage. The other end of the first linkage pivotally connects to a pedal bar. The other end of the second linkage pivotally connects to a pedal installed on the pedal bar in a sliding way. The first and second linkages rotate with respect to the first and second rotational axes, respectively. The user operates the pedals to perform independent reciprocal displacements upward and downward as well as forward and backward.

  • Patent number: 8328699
    Abstract: An exercise step with air-cushioning legs. The exercise step (1) includes a plate-shaped panel (10), and air-cushioning legs (30). Each of the air-cushioning legs is provided under the panel to support the panel, and absorbs a load applied to the panel by air cushioning effect. The exercise step has a high air cushioning effect, thus protecting a user's knees from injury, allowing the user to exercise in comfort and safety, and minimizing noise generated during a cushioning operation. Further, the exercise step prevents the panel from being deformed due to a load applied to the panel.

  • Patent number: 8323155
    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.
