An exercise treadmill is disclosed having a flexible, endless belt entrained around a pair of spaced rollers and having a slider bed disposed under the upper reach of the belt. The slider bed is of a heat-conducting metal plate, and is supported by an open frame such that air may freely flow under the slider bed to carry away heat generated by the upper reach of the belt (with the weight of the runner supported thereon) functionally sliding on the slider bed. The frame, slider bed supports, and slider bed are constructed in such manner as to permit limited vertical flexing movement of these parts when a user runs or walks on the upper reach of the belt supported by the slider bed so as to absorb shock and cushion the impact of the user\s feet.

An exercise treadmill having a frame, said frame comprising a pair of spaced side members extending generally lengthwise of said treadmill, a pair of generally parallel, spaced rollers journaled on said side members and extending transversely between said side members, an endless belt entrained around said rollers, said belt having an upper reach on which a user of said treadmill runs or walks and a lower reach, means for driving one of said rollers and said belt, said belt moving along an endless path around said rollers, and means carried by said frame for supporting said upper reach of said belt and for effectively dissipating heat therefrom generated by the friction of said upper reach of said belt rubbing on said supporting means, said support means comprising a metal plate disposed generally at the elevation of said frame side members and below said upper reach of said belt having a length sufficient so as to substantially continuously support said upper reach between said rollers and a width somewhat less than the distance between said side members such that a gap is present between the sides of said plate and each of said side members, said support means further comprising a plurality of transverse beams disposed below said upper reach with said plate bearing thereon, said beams being secured to said side frame members and being spaced from one another, with the area of said plate in contact with said beams being small in relation to the area between said beams such that frictional heat generated by said rubbing on said plate is conducted from said belt into said plate, and such that relatively cool ambient air between the upper and lower reaches of said belt is heated by the lower face of said face, and such that the heated air is exhausted from the below said plate via said gaps, said beams being sufficiently flexible in vertical direction so as to at least in part cushion the impact of a runner\s feet on said belt.
