<p>Treadmill (1) for running exercise, comprising a frame (2), having a continuous belt (4) guided around at least one front motor-driven drive roller (5') and a rear roller (5); and an arched damping plate (6) arranged beneath the continuous belt (4), for damping of impact from the foot of a runner. The damping plate (6) is arch-formed with a maximum height adjacent to the middle of the longitudinal extension of the plate (6), and having a stiffness allowing downward deflection of the damping plate by the weight of a person running on same. The rear end of the damping plate (6) is fixedly supported in a point at the rear end (7) of the frame (2), whereas the remaining part of the damping plate (6) is floating freely upon the frame (2). Rubber blocks (8, 9, 10) are connected with the frame at the underside of the damping plate (6), thus establishing a spring-like contact between the damping plate (6) and the frame (2), when a runner lands with its weight on the treadmill.</p> |
