1. An exercise treadmill, comprising:
- a frame structure including, a pair of spaced apart longitudinal frame members for providing longitudinal structural support for said frame structure;
a pair of rotatable pulleys secured to said frame, said pulleys being positioned substantially parallel to each other;
a drive unit for rotating a first one of said pulleys;
a deck member;
a belt secured over said pulleys so as to move in a longitudinal direction over said deck member when a first of said first pulleys is rotated;
a control panel secured to said frame structure and operatively connected to said drive unit wherein said control panel permits a user to control the speed of said belt; and
a deck support structure including a first resilient member secured to said deck; and
an adjustment mechanism including a moveable support member adapted to move parallel to said longitudinal frame members from a first position that provides a minimum or no support for said deck member into a second position between said first resilient member and a portion of said frame structure such that said first resilient member is effective to provide resilient support for at least a portion of said deck on said frame structure.

Abstract
To provide variable resilient support for the deck of an exercise treadmill one or more resilient members are secured to the deck and a moveable support member is used to selectively engage the resilient members to provide support for the deck. A user operated adjustment mechanism can be used to move the support member or support members longitudinally along the treadmill thus effectively changing the number of resilient support members supporting the deck.

a pair of rotatable pulleys secured to said frame, said pulleys being positioned substantially parallel to each other;
a drive unit for rotating a first one of said pulleys;
a deck member;
a belt secured over said pulleys so as to move in a longitudinal direction over said deck member when a first of said first pulleys is rotated;
a control panel secured to said frame structure and operatively connected to said drive unit wherein said control panel permits a user to control the speed of said belt; and
a deck support structure having a plurality of resilient members including a first and a second resilient member spaced laterally apart and secured to said deck at approximately the same longitudinal position; and
an adjustment mechanism including;
a first moveable support member adapted to move parallel to and adjacent to a first of said longitudinal frame members from a first position that provides a minimum or no support for said deck member into a second position between said first resilient member and a portion of said frame structure such that said first resilient member is effective to provide resilient support for at least a first portion of said deck on said frame structure;
a second moveable support member adapted to move parallel to and adjacent to a second of said longitudinal frame members from a first position that provides a minimum or no support for said deck member into a second position between said second resilient member and a portion of said frame structure such that said second resilient member is effective to provide resilient support for at least a second portion of said deck on said frame structure; and
a user operable translation mechanism including a user interface for permitting the user to selectively move said first and second support members from said first positions to said second positions. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
