<p><P>PROBLEM TO BE SOLVED: To improve beauty of the surface of a nonslip body by performing curved deformation while maintaining a contraction prevention function and thinning the thickness during attaching. <P>SOLUTION: The staircase nonslip member 10 comprises a synthetic resin-made nonslip body 11 fitted to a gold base frame 30 with fixing screws 5 on the ends of treads 2 of a staircase 1, glass fiber contraction prevention core strings 21, 22 and 23 buried in the anti-skid body 11. The nonslip body 11 includes recesses 14 avoiding interference with head parts 5a of the fixing screws on a lower face, and is formed in the curved deformation. The contraction prevention core string is formed of a center core string 21 arranged in a center part of the nonslip body 11, and sideward core strings 22 and 23 arranged at two parts divided into regular intervals on both the sides on the same face from the center part, and formed in the curved deformation by following the curved deformation of a width direction of the nonslip body 11. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
