  • Patent number: 5484363
    Abstract: An exercise apparatus especially suitable for simulating mogul skiing conditions. The apparatus may comprise a base which supports a rotatable component which, in turn, supports a platform for supporting a user. The rotational component includes a unidirectional element limiting the direction of rotation of the rotational component to a single direction. A biasing assembly assists and resists the movement of the rotational component and varies the speed of the rotational component in response to a displacement of the rotational component. An alternative exercise apparatus includes a pair of spaced rotational components driven by a prime mover via a power transmitting element. A platform is operatively connected to the pair of rotational components via a platform support assembly. One rotational element leads the other rotational element so as to vary the angular disposition of the platform throughout the rotation of the rotational elements. The prime mover is preferably a variable speed motor.

  • Patent number: 5470295
    Abstract: A rowing exercise machine comprises a base, a first swinging member, a second swinging member, a seat tube, a seat, a third swinging member, a first pulley, a second pulley, a pull cable, a hand grip, and two pedals. A rowing exercise is brought about by a person sitting on the seat of the rowing exercise machine, with the person's feet pedaling the pedals and the person's hands holding the hand grip to pull rearwards the pull cable to cause the first swinging member and the third swinging member to move closer so as to actuate the seat tube to move upwards and rearwards. As the pull cable is relieved of the pressure exerting thereon, the seat tube is caused by the person's weight to move forwards and downwards so as to actuate the first swinging member and the third swinging member to move away from each other in opposite directions.

    Abstract: A pool for simulating water-skiing includes a pool body, a pumping plant which pumps water into the pool body as a stream just under the surface of the water in the pool body, a track supported above the periphery of the pool body, an automatic traveling member engaged with the track and capable of automatically traveling along the track, and a tow rope having one end attached to the traveling member. To practice standing up on water skis at the beginning of water-skiing, the traveling member is made to move along the track thereby pulling the skier from a remote position, for example, to a position in the stream of water injected into the pool. If kept at this position the skier can practice skiing with little difficulty. To simulate slaloming, the automatic traveling member can be controlled to travel back and forth along the track so that the skier's position relative to the stream of injected water is varied.

A carriage is provided for riding along the rails, and a first resilient element provides a restoring force on the carriage directed toward the center of the rails. Platforms for a user's feet are pivotally attached to the carriage off-center from the centerline of the platforms so that the natural action by a user in shifting weight from one platform to the other platform in operation causes the respective platforms to pivot in the correct direction to simulate the action of parallel skiing. The first resilient element is fastened to the carriage at about a mid-point. One end of the first resilient element in the preferred embodiment passes around a roller attached to one of the end brace elements, extends back toward the middle of the rails, and is clamped at a clamp assembly attached to an additional brace element between the rails.
