Abstract
An exercise machine has a frame that has a base with an upright member. The upright member is formed to have a race to receive wheels to interconnect a second frame to the upright member. A cable and pulley structure interconnects exercise structures to cause movement of the second frame relative to the first frame. A user is positioned on a seat connected to the second frame to resist movement of the second frame relative to the first frame. A butterfly structure is provided that has a mechanical linkage to interconnect the link arms to a butterfly lever rotatably connected to deflect the cable of an associated cable arrangement.
Claims30
An exercise machine comprising:
- a first frame having a base for positioning on a support surface, said first frame including an upright member secured to said base to extend upwardly therefrom;
- a second frame positioned proximate said upright member for movement relative thereto and therealong;
- a first guide assembly and a second guide assembly spaced apart from each other and positioned one above the other, said first guide assembly and said second guide assembly each interconnecting said second frame and said upright member for guiding said second frame in moving substantially linearly upwardly and downwardly relative to said upright member;
- a user support secured to said second frame to support a sitting user thereon;
- operation means connected to one of said first frame and said second frame and positioned for operation by a user positioned on said user support to perform exercises;
- and
- linking means interconnecting said operation means to said first frame and to said second frame to urge movement of said second frame upward relative to and along said upright member upon operation of said operation means by a user against the weight of the said second frame and the weight of a user positioned on said user support, said linking means including a lever mechanism movably connected to said first frame and a guide connected to said second frame spaced from said lever mechanism;
- and
- a cable associated with said lever mechanism and trained about said guide, said cable being connected to said operations means and to said linking means to urge said second frame to move relative to said first frame upon operation of said operation means by a user.

- and
- linking means interconnecting said operation means to said first frame and to said second frame to urge movement of said second frame upward relative to and along said upright member upon operation of said operation means by a user against the weight of the said second frame and the weight of a user positioned on said user support, said linking means including a lever mechanism movably connected to said first frame and a plurality of guides connected to said second frame spaced from said lever mechanism;
- and
- a cable associated with said lever mechanism and trained about each guide of said plurality of guides, said cable being connected to said operations means and to said linking means to urge said second frame to move relative to said first frame upon operation of said operation means by a user.

An exercise machine comprising:
- a frame;
- user support means secured to said frame structure to support a user thereon during the performance of exercise;
- a left butterfly arm rotatably connected to said frame to rotate about an axis;
- a right butterfly arm rotatably connected to said frame to rotate about an axis;
- a butterfly lever rotatably connected to said frame having a proximal end positioned proximate said left butterfly arm and said right butterfly arm and a distal end moveable toward and away from said frame;
- linkage to link said proximal end of said butterfly lever to said left butterfly arm and said right butterfly arm so that upon movement of either said left butterfly arm or said right butterfly arm said proximal end of said butterfly lever moves and said distal end of said butterfly lever moves;
- and
- a cable positioned proximate said distal end of said butterfly lever for displacement upon movement of said butterfly lever.
