  • Patent number: 6350219
    Abstract: An exercise machine includes a frame, a removable seat, and a shaft horizontally mounted on the frame, which rotates about its longitudinal axis. Attached to the shaft is at least one weight arm and at least one work arm. The work arm can be releasably connected and take multiple forms, each adapted for particular exercises. When an exerciser pulls or pushes on the work arm, the shaft rotates and carries the weight arm in an arc from a starting or first position to a second position. Because the weight arm travels in an arc, the resistance to the exerciser varies over the course of the exercise. Further, the starting or first position of the weight arm may be adjusted to change the starting resistance to the exerciser.

Pivotable levers are connected to the carrier symmetrical about the axis of rotation. A cord hangs from each lever. The cords join into a single cord that holds a weight so as to produce equal and opposite torques on the carrier. A person exerts a force on the carrier sufficient to overcome one of the torques and thereby rotate the carrier. By pivoting the levers the cords hang at different distances from the carrier axis of rotation, thereby changing the amount of torque produced on the carrier by the weight and the amount of force the person must exert to rotate the carrier. A block on the carrier contacts the cord during carrier rotation in a manner that results in a smooth and continuous resistance by the weight on the person's arm.

  • Patent number: 6080091
    Abstract: An improved press arm allows an operator to perform either a traditional straight chest press exercise or to incorporate "butterfly" motion during the performance of the chest press exercise. A main arm is pivotally coupled to the frame of the exercise machine at a main pivot in the same manner as conventional press arms. The main arm includes a cross-beam to which a pair of handle arms are pivotally coupled at secondary pivots. The axes of the secondary pivots are orthogonal to the axis of the main pivot and are inclined with respect to vertical when the press arm is in a rest position. This inclination causes the handle arms to assume a natural rest position under the influence of gravity. The rest positions of the handle arms place the press arm handles at a comfortable starting position for performance of a press exercise. Stops to limit the inward or outward travel of the handle arms are not necessary.

  • Patent number: 6022298
    Abstract: An exercise apparatus for exercising the entire body, but in particular the muscles of the legs and the buttocks includes a frame, a lower leg support that has a rearward facing surface for supporting a lower leg area of a user, and a yoke member. The yoke member has a rearward portion that is constructed and arranged to be gripped for lifting by a user, and a forward portion that is pivotally mounted to the frame at a location that is positioned forward of said rearward facing surface of the lower leg support. The apparatus also includes resistance structure for imparting resistance against lifting the rearward portion of said yoke member by the user. This apparatus is particularly suited for doing "lunge" exercises in a way that is both more efficient in the working of targeted muscle groups and is less stressful on the user's knee joints than conventional free weight based lunge exercises are.

  • Patent number: 6004246
    Abstract: A lumbar exercise machine having an adjustable pad assembly for engaging the legs above and below the knees while the legs extend generally forward with the feet against a foot rest and the knees bent so that the thighs and calves form an obtuse angle. A lock mechanism is provided to secure the pad assembly in the aforementioned position with the femurs restrained against movement so that the hips, buttocks and thighs cannot move during the exercise. The exerciser then moves his back against a movement arm in opposition to a resistance mechanism connected to the movement arm. The machine is adjustable to properly position a particular user for the exercise. One machine for home use utilizes dead weights plus the user's weight as the resistance mechanism while another machine for commercial use utilizes a compound weight stack as the resistance mechanism.

  • Patent number: 5967954
    Abstract: An exercise machine has a frame, a seat and a pair of exercise arm assemblies. Each of the exercise arm assemblies is pivotally attached to the frame. Handles at the outer extremities of the arm assemblies are gripped by the user to perform the intended exercise. The geometry of the arms and their pivot points is arranged so that the handles of the assemblies follow arcuate paths which converge as the handles are moved forwardly. At a starting position for a press exercise, the handles are approximately in line with the shoulders of the user. As the handles are pushed forwardly against an exercise resistance, they converge inwardly until they are nearly touching when the user's arms are fully outstretched. The machine may also be used to perform a seated-row exercise, in which case the handles are pulled rearwardly against the exercise resistance.
