Abstract
A stepper includes a base defining a horizontal plane, a first track structure coupled to the base and configured to translate along a first track, a first force receiving member coupled to the first track structure, a second track structure coupled to the base and configured to translate along a second track, a second force receiving member coupled to the second track structure, and a reciprocating mechanism coupled to the first track structure and the second track structure such that translation of the first force receiving member in a first direction causes the second force receiving member to translate in a second direction opposite the first direction.
Claims21
A stepper, comprising:
- a base defining a horizontal plane;
- a first track structure coupled to the base and configured to translate along a first track;
- a first force receiving member coupled to the first track structure;
- a second track structure coupled to the base and configured to translate along a second track;
- a second force receiving member coupled to the second track structure;
- a reciprocating mechanism configured to selectively i) couple the first track structure and the second track structure in a first configuration such that translation of the first force receiving member in a first direction causes the second force receiving member to translate in a second direction opposite the first direction, and ii) decouple the first track structure and the second track structure in a second configuration such that translation of the first force receiving member in the first direction does not cause the second force receiving member to translate in the second direction opposite the first direction;
- and
- a height adjuster configured to adjust a height, wherein a vertical distance between the first track structure and a ground defines the height.
A method, comprising:
- providing a base defining a horizontal plane;
- coupling a first track structure to the base;
- coupling a first force receiving member to the first track structure;
- coupling a second track structure to the base;
- coupling a second force receiving member to the second track structure;
- coupling a reciprocating mechanism to the first track structure and the second track structure to cause the first track structure and the second track structure responsive to applying a force to either the first force receiving member or the second force receiving member;
- decoupling the reciprocating mechanism from the first track structure or the second track structure to cause the first track structure to move independent to the second track structure responsive to applying a second force to the first force receiving member;
- and
- adjusting an angle of the first force receiving member between a predetermined maximum angle and a predetermined minimum angle.
A stepper, comprising:
- a base defining a horizontal plane;
- a first track structure coupled to the base and substantially parallel to the horizontal plane;
- a first force receiving member coupled to the first track structure and configured to translate along the first track structure;
- a second track structure coupled to the base and substantially parallel to the horizontal plane;
- a second force receiving member coupled to the second track structure and configured to translate along the second track structure;
- and
- a weight coupled to at least one of the first force receiving member and the second force receiving member such that translation of at least one of the first force receiving member and the second force receiving member causes movement of the weight in a direction perpendicular to the horizontal plane.
