  • Patent number: 5980430
    Abstract: A tread board for a treader includes a base board, an elastic layer disposed on top of the base board, a laminate layer disposed on top of the elastic layer, and a surface layer of a smooth surface disposed on top of the laminate layer. The elastic layer provides a buffering function to reduce impact on the user's feet, making the treader safe and comfortable to use. The smooth surface of the surface layer reduces friction between the tread belt and the surface layer and reduces the load of the motor, thereby prolonging the useful life of the tread belt and the motor.
