Variable stride exercise apparatus
First Claim
1. A stationary exercise apparatus, comprising:
- a frame;
a crank system coupled to the frame;
a left movable member coupled to the crank system;
a right movable member coupled to the crank system;
a left foot member operatively associated with a left foot pad;
a right foot member operatively associated with a right foot pad;
a left cam system having a left cam surface and a left cam follower contacting the left cam surface wherein the left cam system couples the left movable member to the left foot member; and
a right cam system having a right cam surface and a right cam follower contacting the right cam surface wherein the right cam system couples the right movable member to the right foot member,wherein the feet of the user imparting forces on the left and right foot members in cooperation with the left cam system and the right cam system may vary the stride substantially instantaneously, andwherein the apparatus is configured such that the feet of the user may travel in a substantially closed path.

Abstract
A variable stride exercise apparatus is described. A variable stride exercise apparatus may include a frame. A crank system may be coupled to the frame. A foot member may be coupled to the crank system. The foot member may include a footpad. A variable stride system may be coupled to the foot member. The variable stride system and the foot member may be coupled such that at least a portion of the variable stride system is under at least a portion of the footpad. The variable stride system may allow a user of the apparatus to vary the length of the user'"'"'s stride during use of the apparatus. The foot of the user may travel in a substantially closed path during use of the apparatus. At least a portion of the apparatus may remain substantially stationary during use.

20. A stationary exercise apparatus comprising:
-
a frame; a crank system coupled to the frame; a left movable member pivotally coupled to the crank system; a right movable member pivotally coupled to the crank system; a left foot member operatively associated with a left foot pad; a right foot member operatively associated with a right foot pad; a left cam system having a left cam surface and a left cam follower contacting the left cam surface, the left cam system operatively associated with the left movable member and the left foot member so that during use of the apparatus the left cam follower may move across the left cam surface allowing the left foot of the user imparting a force on the left foot member in cooperation with the left cam system to vary the stride substantially instantaneously; and a right cam system having a right cam surface and a right cam follower contacting the right cam surface, the right cam system operatively associated with the right movable member and the right foot member so that during use of the apparatus the right cam follower may move across the right cam surface allowing the right foot of the user imparting a force on the right foot member in cooperation with the right cam system to vary the stride substantially instantaneously, wherein the apparatus is configured such that the feet of the user may travel in a substantially closed path. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)

36. A stationary exercise apparatus comprising:
-
a frame; a crank system coupled to the frame; a left arm link coupled to the frame; a right arm link coupled to the frame; a left foot member operatively associated with a left foot pad, said left foot pad having a forward end and a rearward end; a right foot member operatively associated with a right foot pad, said right foot pad having a forward end and a rearward end; a left cam coupled to the crank system so that at least a portion of the left cam is ahead of the rearward end of the left foot pad and behind the forward end of the left foot pad at some time during use; and a right cam coupled to the crank system so that at least a portion of the right cam is ahead of the rearward end of the right foot pad and behind the forward end of the right foot pad at some time during use, wherein the feet of the user imparting forces on the left and right foot members in cooperation with the left cam and the right cam may vary the stride substantially instantaneously, and wherein the left foot member is coupled through the left cam to the crank system and the right foot member is coupled through the right cam to the crank system, the apparatus being configured such that the feet of the user may travel in a substantially closed path. - View Dependent Claims (37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50)
