Abstract

An exerciser includes two rails pivotally attached to a base, two handles pivotally attached to the base, two foot supports having one end pivotally coupled to the handles and the other end slidably engaged with the rail, and a tilting device may tilt the rails relative to the base to different angular positions in order to adjust the moving strokes of the foot supports. A bolt may be rotatably attached to the base and threaded with a follower, and a motor coupled to the bolt for rotating the bolt relative to the base, and for adjusting the follower along the bolt, and the follower is coupled to the rails for tilt the rails relative to the base to different angular positions.

Claims

1. An exerciser comprising:

a base, two rails pivotally attached to said base and rotatable relative to said base to different angular positions,

two handles pivotally attached to said base and rotatable relative to said base, said handles each including a lower portion,

two foot supports each including a first end pivotally coupled to said handle, and each including a second end slidably engaged with said rail,

a foot pedal pivotally attached to each of said foot supports with a pivot pin for allowing said foot pedal to be tilted relative to said foot support.

two levers pivotally coupling said lower portions of said handles to said foot pedals of said foot support respectively,

an arm pivotally attached to said base and pivotally coupled to said rails, and having a rear end movable up and down relative to said base,

a bolt rotatably attached to said base,

a motor coupled to said bolt for rotating said bolt relative to said base, and

a follower threadedly engaged with said bolt for being moved and adjusted along said bolt when said bolt is rotated by said motor, said follower being pivotally coupled to said arm for moving said rear end of said arm up and down relative to said base and for tilting said rails relative to said base to different angular positions.

4. The exerciser as claimed in claim 1, wherein said levers each include a free end bent relative to said lever and acted as a pivot rod for pivotally coupling to said foot pedal and offset from said pivot pin for allowing said foot pedal to be tilted relative to said foot support by said handles and said levers.

8. The exerciser as claimed in claim 1, wherein a coupler is secured between said rails, and a seat is extended from said coupler and pivotally coupling to said arm with a bar.

9. The exerciser as claimed in claim 8, wherein said bar is pivotally coupled to a middle portion of said arm.

10. The exerciser as claimed in claim 1, wherein said foot supports each include a roller attached to said second end of said foot support for slidably engaging with said rails.

11. The exerciser as claimed in claim 1, wherein said rails each include two rods disposed parallel to each other, and a link securing said rods together.
