UNIT FOR PREVENTING SHOES FROM SLIDING

摘要

A unit for preventing shoes from sliding comprises the main elastomer constituent and additional ones, metal spikes with the bases which are rigidly fixed in the elastomer main constituent and additional ones. On the wider side the main elastomer constituent has two openings and the metal spikes with the bases, and on the narrower elastomer sides rivets are made by two, shoe loop-and-hook fasteners are fixed oppositely as regards to the longer axis of the elastomer. An additional elastomer constituent is shaped as a square or a rectangle fixed with the main elastomer constituent by steel cramp irons 24/6. The height h of a spike and the radius of base thereof are in a ratio h : r = 4 : (5-3.2), the thickness of the spike S and the diameter of base thereof D are in a ratio of S : D = 1 : (1-0.6), and the radius of a circumscribing circle for arranging the spikes is less than or equal to three radii of the base of a spike.
