  • Patent number: 8475346
    Abstract: A storable exercise apparatus for home use. The apparatus includes an upright tower, a base structure, a bench frame, and a bench attached to the bench frame. A set of flexible pull lines coupled to a resilient spring system are carried within the tower structure. The user exercises by pulling the pull lines against the bias of the spring system. The grips for the pull lines are mounted at the top of the tower and generate significant tipping force on the tower when the apparatus is in use. To prevent tipping, the bench frame has pivotal and load-transmitting connections with the tower structure; the tower is stabilized by the weight of the user on the bench. The bench may be placed in either a raised or lowered position, and can be stored by collapsing and pivoting it so that it abuts the tower vertically.

  • Patent number: 7264576
    Abstract: An elliptical exercise machine in which elongate foot pedaling members are rotatably connected to a crank assembly including a pair of diametrically opposed cranks. Toward one end of each foot pedaling member, an arm is pivotally mounted to the exerciser frame and has a free end with a roller that rollably supports the end of the foot pedaling member. A spring is mounted between the frame and each arm. The springs reduce shock and jarring movement for the user as the user traverses generally elliptical paths using the two foot pedaling members.
