ABSTRACT:
A tread for surface contact with various surfaces of a human body, as feet, chest, abdomen, etc., has a base with upwardly projecting tines. A surface tread is provided in contact with, and is softer than, the tines. The relative hardness of the tines and the surface tread are designated. When the surface tread is urged toward the tines by a body portion urged against the surface tread, the tines, because of the relative hardness of the tines and the surface tread, will depress the surface portion and form dents or depressions therein. These depressions will mechanically resist side movement of the contacting tine portion and thus mechanically interlink the surface portion and the tines and thus the tines bend at midportion and with relatively little movement of the tip portions of the tines which is restrained because of the mechanical engagement with the tines and the depressions. The tines move with the pressure of a human body portion urged thereagainst and move in the opposite direction as the pressure is released or eased and thus, a massage action obtains in the skin portion of the body portion urged toward and relieved away from the surface tread.
