Embodiment Construction

[0019] Figure 1-4 Exercise device 20 is shown according to an example embodiment. As described below, exercise device 20 provides a person exercising with a variety of user-selectable motion paths. The user is able to toggle (shift) between the different available paths by simply applying different forces to the foot links of the exercise device. In other words, exercise device 20 is an adaptive athletic exercise device in that it automatically adapts or responds to the movements of the person exercising. Exercise device 20 provides this freedom of movement through relatively few, if any, cantilevered structural elements. Therefore, the structural rigidity and overall weight of the exercise device 20 can be reduced.

[0020] Exercise device 20 includes frame 22, crank assemblies 24R and 24F (collectively referred to as crank assemblies 24), guides 26R and 26L (collectively referred to as guides 26), foot pads 28R and 28L (collectively referred to as foot pads 28), foot pad...

Abstract

An exercise device includes a first crank arm assembly (24R) and a second crank arm assembly (24F) supporting opposite portions of a guide (26). A first foot pad (28) is coupled to the guide (26) to reciprocate along the guide. A foot pad link (30) has a first end portion (80) pivotably connected to the foot pad (28) and a second end portion (82) pivotably supported about an axis that is movable along one of a plurality of user selectable paths, each of the plurality of user selectable paths having a different length.

Description

technical field [0001] The present invention relates to exercise devices. Background technique [0002] Most exercise devices provide a fixed, predetermined path of exercise motion. Some exercise devices now offer user-defined paths of exercise motion. However, these exercise devices employ cantilevered structural elements, increasing structural stiffness requirements and adding to the overall weight of the exercise device. Contents of the invention [0003] The exercise device of the present invention includes: a frame; a first crank assembly connected to the frame; a second crank assembly connected to the frame; a first guide having a a first part to rotate with the first crank assembly and a second part connected to the second crank assembly to rotate with the second crank assembly; a first foot pad with the first guide connected to reciprocate along said first guide; a first foot pad connector having a first end pivotably connected to said first foot pad and being p...
