Abstract

The present invention provides a cushioning board of treadmill. A braided bamboo plastic plate is formed by applying bamboo strips of suitable thickness and width, which are divided as warp bamboo strips and weft bamboo strips so that at least one warp bamboo strip and at least one weft bamboo strip are arranged to intersect and stack each other and thus being braided. The bamboo plastic plate can be stacked to a desired thickness to form a braided bamboo plastic stacking board to improve strength and retaining cushioning resilience. Alternatively, the warp bamboo strips are arranged to juxtapose each other to directly stack on juxtaposed weft bamboo strips to form a stacked bamboo plastic plate. In the above-mentioned arrangements, the uppermost braided bamboo plastic plate or the stacked bamboo plastic plate can be bonded with adhesives to a skidding resistance board. Through stamping, the surface of the skidding resistance board can be recessed according to the patterns of the braided bamboo plastic board or the stacked bamboo plastic plate to form a corrugated massage pattern. As such, a cushioning board for jogging loop is provided and the cushioning board that is formed of stacking braided bamboo plastic board or stacked bamboo plastic plate or both provides excellent cushioning and sole massaging effects.
