FIELD: mechanical engineering. SUBSTANCE: running track for investigating runner's and walker's movements has supporting members with spherical necks at their ends. Each inner neck of supporting members is inserted into guide of spherical support of supporting member orientation unit. Antifriction is positioned on top of supporting member, which is arranged on antifriction rack mounted on flexible member. Transformation unit has truncated spherical support with rectangular outer sphere and bearing spherical guide mounted for rotation about vertical and longitudinal axes. Casing has side guide, vertical front and rear walls and lower rectangular inner sphere, vertical and inclined guides and their pushers. Outer neck of supporting member is inserted into bearing guide. Pushers are contacting with spherical support at one side and with sensors at other side. Side sensor is contacting with outer neck end and rack is contacting with base through flexible member. Such construction allows effect of drive belt upon front and rear sensors to be eliminated. EFFECT: increased efficiency and provision for obtaining precise data. 6 dwg |
