ABSTRACT:
A treadmill for walking exercise or medical testing has the the usual frame mounting rollers around which an endless belt is driven through a lower course and an upper course, the upper course of the belt being supported by an improved deck particularly adapted to rest on longitudinal support members of the frame.
One improvement lies in connecting one end of a planar deck to a anchor member by a flexible hinge, the member being attachable to the frame and the flexibility of the hinge allowing the deck to yield to the impact of a user's tread both vertically and longitudinally of the deck.
Many available treadmills are designed to receive a standard deck which is essentially a rectangular plank bounded by flat surfaces which enclose a prismatic volume. The present deck is rectangular and planar but has recesses rabbetted along its underside opposite the supporting frame members, the recesses being filled with strips of compressible, elastomeric material located within the cubic volume of the standard deck. Consequently the present deck can fit in the standard volume and further provide shock absorption. The deck is therefore useful, without modification, in treadmills of different manufacture.
