Abstract

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.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 103 words
A surface for contact by human skin intermittently urged thereagainst, comprising a base member having spaced apart, upwardly projecting, flexible tines, each of said tines having a height a plurality of times greater than its diameter; and an upper surface member having a lesser hardness than said tines, disposed above and being provided with depressions therein when the upper surface of said tines are relatively urged thereagainst, and being mechanically engaged with the said tines through said depressions and the upper portions of said tines urged into said depressions, said tread surfaces reacting to massage human skin portions urged toward such upper surface.
Claim 2
Dependent Claim 103 words
A surface for contact by human skin intermittently urged thereagainst, comprising a base member having spaced apart, upwardly projecting, flexible tines, each of said tines having a height a plurality of times greater than its diameter; and an upper surface member having a lesser hardness than said tines, disposed above and being provided with depressions therein when the upper surface of said tines are relatively urged thereagainst, and being mechanically engaged with the said tines through said depressions and the upper portions of said tines urged into said depressions, said tread surfaces reacting to massage human skin portions urged toward such upper surface.
Claim 3
Dependent Claim 29 words
