Abstract: A platform for supporting a conveyor belt of a treadmill includes a wooden plate, a reinforcement plate above the wooden plate, and a shock-absorbing plate sandwiched between the wooden plate and the reinforcement plate. The shock-absorbing plate has a surface facing the wooden plate base, and a plurality of cushions protruding from the surface and stopping against the wooden plate for providing good elastic support force and cushion effect.

Abstract: A hardness adjustable platform for supporting a conveyor belt of a treadmill includes a platform body having internal spaces, and a plurality of elastic fillers moveably and respectively disposed in the internal spaces of the platform body for providing a cushion effect. The fillers are moveable relative to the platform body by an external force and divide the platform body into first and second regions having different hardness. As a result, the runner who uses the treadmill equipped with the aforesaid platform may adjust the positions of the fillers according to his/her physical condition and running speed to change the hardness distribution of the platform so as to enhance his/her running efficiency and reduce the risk of exercise injury.

Abstract: A foot cushion adjustment mechanism includes a base frame having a mounting portion, a cushion member having a through hole defining a first opening and a locating member disposed in the through hole, and an adjustment device having a body portion inserted through the locating member and a first end portion inserted through the first opening and pivotally coupled to the mounting portion. Biasing the adjustment device causes the cushion member to be moved linearly relative to the base member to adjust the distance between the cushion member and the base member.

Abstract: A folding treadmill positioning structure includes a base frame, a treadmill platform, a first linkage connected between the base frame and the treadmill platform at the front side and defining a retaining portion, and a positioning device set, which includes a constraint member movably arranged on the rear side of the treadmill platform, a retaining member pivotally mounted on the front side of the treadmill and a connection member connecting the constraint member and the retaining member. When the treadmill platform is moved to the received position, the retaining member is forced into engagement with the retaining portion, locking the treadmill platform in the received position.
