Title:
NONSLIP TIRE
Document Type and Number:
Japanese Patent JPS63173705
Kind Code:
A
Abstract:
PURPOSE:To facilitate projection/retraction of a nonslip, by making a groove arranged with two rows of single sides of a zipper in the tread of tire, then inserting the nonslip associated with the other sides of the zipper into the groove such that the nonslip can be projected/retracted by engaging the groove zipper or the nonslip zipper selectively. CONSTITUTION:When an engaging chip 7 moves to side A, a nonslip zipper 5 is separated from a zipper 3 on the groove wall face then engaged with a zipper 4 on the groove wall face. Consequently, a nonslip 2 enters into a groove 9 in tread so as to release slip-in function. When the engaging chip 7 moves in direction B, engaging condition of the zippers 3, 4 is reversed and the nonslip 2 projects from the groove 9 to the tread so as to exhibit nonslip function. Operation of said engaging chip 7 is carried out through a wire 8. With such arrangement, projection/retraction of the nonslip is facilitated.
