Abstract

PURPOSE:To measure a slip resistance factor to eliminate the measure error due to spring vibration or the like, by setting the first and the second materials to be measured so that prescribed parts are brought into contact with each other and by including both materials as one body until the second material starts slipping. CONSTITUTION:A turning table 9 is made level, and a slip preventing material 4 for stairs to be measured is fitted to a turning member 18, and the member 18 is turned to make a desired contact angle psi between a shoe bottom to be measured and the slip preventing material. Next, a motor 12 is driven, and a thread 14 is taken up by a take-up pulley to turn the turning table 9 very slowly. An inclination angle theta of a line ee' to the level and the force Wh by which a linear material 29 suspends the heel of a shoe 5 are obtained when the shoe 5 starts slipping on the slip preventing material 4 by the turning of the turning table 9, and a slip resistance factor mu is obtained. Thus, slip resistance factors for various contact angles psi are obtained easily.
