TREAD MILL HAVING VIDEO LINKED WITH SPEED IN FRONT, AND TRAVELING SURFACE TILTABLE FORWARD, BACKWARD AND OBLIQUELY WITH TRAVELING SURFACE SPEED FOLLOWING SPEED OF RUNNER

摘要

PROBLEM TO BE SOLVED: To provide a tread mill which has a video linked with speed in front and a traveling road surface tiltable in arbitrary directions and whose speed of traveling road surface follows up the arbitrary speed of a runner. SOLUTION: A video instrument 9 is installed above the front part of a main body frame 1. Besides, a traveling road surface frame 2 is supported through a spherical bearing 3 on this frame, and its front end is vertically moved by two inclined cylinders 6. Further, the position of the runner is detected by position sensors 10-13 at the side of a traveling road surface, the speed of a traveling road surface 4 is linked with the speed of the runner, and the moving/expanding speed of video is linked with the speed of the runner as well.
