ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to exercise equipment, and more specifically, to methods and apparatus for absorbing energy associated with exercise movement.
BACKGROUND OF THE INVENTION
One of many factors to be considered in the design of exercise equipment is energy absorption. On treadmills, for example, impact is created each time a person's foot lands on the tread and/or deck. In the absence of an energy absorption system, the impact rebounds into the person's foot and may cause harmful stress to the person's joints. In recognition of this potential problem with treadmills, equipment designers have developed systems to absorb or dissipate the impact so that it does not rebound into the exerciser's feet and legs. Examples of such systems are disclosed in U.S. Pat. No. 4,350,336 to Hanford and U.S. Pat. No. 5,382,207 to Skowronski et al. Despite these advances in the art, room for improvement remains.
SUMMARY OF THE INVENTION
The present invention provides an improved energy absorbing system for exercise equipment. On a preferred embodiment treadmill, the system is disposed between the deck and the frame and adjusts to accommodate the various needs of different users. Additional features and/or advantages of the present invention will become apparent from the detailed description which follows.
