Structure of an anti-slip floor unit

Abstract

An anti-slip floor unit includes a board formed thereon with a plurality of spherical swells, each of the spherical swells having a protuberance a center thereof, the spherical swells being equidistantly arranged on a top of the board, whereby the dirt can be prevented from accumulating in blind spots thereby making it easier to clean the anti-slip floor unit and prolonging its service life.

I claim:  
     
         1 . An anti-slip floor unit comprising a board formed thereon with a plurality of spherical swells, each of said spherical swells having a protuberance a center thereof, said spherical swells being equidistantly arranged on a top of said board.  
     
     
         2 . The anti-slip floor unit as claimed in  claim 1 , wherein a distance between a top of said protuberance and a bottom of said board is 4.5 mm.  
     
     
         3 . The anti-slip floor unit as claimed in  claim 1 , wherein a distance between two adjacent ones of said spherical swells is 47 mm.  
     
     
         4 . The anti-slip floor unit as claimed in  claim 1 , wherein said spherical swells have a diameter of 20 mm.
