Abstract
Exercise apparatus, for example of the type disclosed in the U.S. Pat. No. 6,705,976, is provided with a resistance source for exerting a counterforce to the force applied by the user. This resistance source includes at least two of (1) means, such as a cylindrical rod or the like, for removably holding one or more weights, (2) at least one hook or the like for removably attaching one or more springs, and (3) means for removably attaching one or more damping devices.

16. Exercise apparatus comprising, in combination:
-
(a) a frame;
(b) a cable arranged in the frame and having a proximal end and a distal end, the proximal end of the cable being located outside the frame and being attached to a gripping device that enables a user to exert a tensile force to the cable by pulling the cable in a desired direction, the distal end of the cable being located within the frame;
(c) a resistance source, located within the frame and adapted to be coupled to the distal end of the cable, such that when the proximal end of the cable is pulled by a user, the resistance source exerts a counterforce to the cable, said resistance source including;
(1) a plurality of weights arranged in a weight stack, one or more of said weights being adapted to move upward when lifted by the cable;
(2) a retaining member disposed above said weight stack-and coupled to the distal end of the cable so as to move upward when lifted by the cable, said retaining member having at least two of (i) first means for removably attaching an upper end of a tension spring, (ii) second means for retaining a separate weight; and
(iii) third means for selectively coupling to said weight stack; and
(3) fourth means disposed on the frame for removably attaching a lower end of the tension spring. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

- 27. In exercise apparatus having a fixed frame with a frame member, a movable member arranged in the frame and adapted for movement by a user, and a source of resistance arranged in the frame and connected to said movable member, a removable device for removably connecting a tension spring to provide at least a portion of said source of resistance.

29. In exercise apparatus having a frame and a stack of weights, a removable device for removably connecting a tension spring to a topmost weight in said weight stack, said device comprising:
-
(a) an elongate bar having means for attachment of one end of said tension spring, said bar being adapted to extend across, and to be clamped onto, a top surface of said topmost weight, said bar having at least one hole therein;
(b) at least one S-shaped clamp adapted to be inserted between said topmost weight and a lower weight in said weight stack, said clamp having at least one hole therein; and
(c) a bolt, adapted to be passed through said openings in said bar and said clamp, for securing said bar and said clamp together. - View Dependent Claims (30)
