Abstract

Abstract A shoe sole made of a flexible, resilient material and having a central longitudinal passageway therein. A fresh air intake is located at the heel region of the sole and provides ventilation air to the passageway. With each stride, the wearer pumps air from the heel through the longitudinal passageway and then out upwardly extending vents to the interior of the shoe.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 118 words
An article of manufacture comprising: a flexible sole having at least one longitudinal passageway therein, (b) a vertical outlet vent extending upwardly from the longitudinal passageway, (c) an extension member joined to the sole, said extension member having an upwardly extending intake passageway for drawing outside air into the longitudinal passageway to be pumped to the vertical outlet vent, and (d) a longitudinal ridge attached to the bottom of the sole and extending generally the length of thee longitudinal passageway for affecting the momentary closure of the longitudinal passageway at progressive locations along the length of the longitudinal passageway during a step whereby air is pumped along the longitudinal passageway from the intake passageway to the outlet vent.
Claim 2
Dependent Claim 118 words
An article of manufacture comprising: a flexible sole having at least one longitudinal passageway therein, (b) a vertical outlet vent extending upwardly from the longitudinal passageway, (c) an extension member joined to the sole, said extension member having an upwardly extending intake passageway for drawing outside air into the longitudinal passageway to be pumped to the vertical outlet vent, and (d) a longitudinal ridge attached to the bottom of the sole and extending generally the length of thee longitudinal passageway for affecting the momentary closure of the longitudinal passageway at progressive locations along the length of the longitudinal passageway during a step whereby air is pumped along the longitudinal passageway from the intake passageway to the outlet vent.
Claim 3
Dependent Claim 15 words
The article of manufacture of claim 1 wherein the flexible sole is made from rubber.
Claim 4
Dependent Claim 16 words
The article of manufacture of claim 1 wherein the flexible sole is made from elastomeric material.
Claim 5
Dependent Claim 17 words
The article of manufacture of claim 1 wherein the longitudinal passageway is formed centrally in the sole.
Claim 6
Dependent Claim 35 words
The article of manufacture of claim 1 wherein the longitudinal passageway has a generally crescent-shaped cross-section and the longitudinal ridge has a cooperating curved upper surface that momentarily closes the longitudinal passageway during a step.
Claim 7
Dependent Claim 28 words
The article of manufacture of claim 1 wherein a reinforcing member is disposed along the length of the longitudinal passageway between the longitudinal passageway and the longitudinal ridge.
Claim 8
Dependent Claim 17 words
The article of manufacture of claim 1 wherein the longitudinal ridge is integrally formed with the sole.
Claim 9
Dependent Claim 15 words
The article of manufacture of claim 1 wherein the number of longitudinal passageways is three.
Claim 10
Dependent Claim 93 words
An article of manufacture comprising: (a) a flexible sole having at least one longitudinal passageway therein. (b)) a vertical outlet vent extending upwardly from the longitudinal passageway, (c) an extension member joined to the sole, said extension member having an upwardly extending intake passageway for drawing outside air into the longitudinal passageway to be pumped to thee vertical outlet vent, and (d) a longitudinal ridge attached to the bottom of the sole for pumping the air along the longitudinal passageway and (e) an indented channel disposed on each side of the longitudinal ridge.
Claim 11
Dependent Claim 93 words
An article of manufacture comprising: (a) a flexible sole having at least one longitudinal passageway therein. (b)) a vertical outlet vent extending upwardly from the longitudinal passageway, (c) an extension member joined to the sole, said extension member having an upwardly extending intake passageway for drawing outside air into the longitudinal passageway to be pumped to thee vertical outlet vent, and (d) a longitudinal ridge attached to the bottom of the sole for pumping the air along the longitudinal passageway and (e) an indented channel disposed on each side of the longitudinal ridge.
Claim 12
Dependent Claim 138 words
A ventilated shoe comprising: (a) an upper body designed to accommodate the foot of a wearer, (b) a flexible sole joined to the upper body, said flexible sole having at least one longitudinal passageway therein, (c) a vertical passageway vent extending upwardly from the longitudinal passageway, (d) an extension member joined to the sole, said extension member having an upwardly extending intake passageway for drawing outside air into the longitudinal passageway to be pumped to the vertical vent passageway, and (e) a longitudinal ridge attached to the bottom of the sole and extending generally the length of the longitudinal passageway for effecting the momentary closure of the longitudinal passageway at progressive locations along the length of the longitudinal passageway during a step whereby air is pumped along the longitudinal passageway from the intake passageway to the outlet vent.
Claim 13
Dependent Claim 138 words
A ventilated shoe comprising: (a) an upper body designed to accommodate the foot of a wearer, (b) a flexible sole joined to the upper body, said flexible sole having at least one longitudinal passageway therein, (c) a vertical passageway vent extending upwardly from the longitudinal passageway, (d) an extension member joined to the sole, said extension member having an upwardly extending intake passageway for drawing outside air into the longitudinal passageway to be pumped to the vertical vent passageway, and (e) a longitudinal ridge attached to the bottom of the sole and extending generally the length of the longitudinal passageway for effecting the momentary closure of the longitudinal passageway at progressive locations along the length of the longitudinal passageway during a step whereby air is pumped along the longitudinal passageway from the intake passageway to the outlet vent.
