Abstract

Abstract A portable foot and/or leg exercising apparatus for an operator which includes a first and second plate a mechanism for pivotally connecting said first and second foot plate together, centrally positioned between the first and second plate and extending vertically from each of the first and second plates and a mechanism disposed within or around the pivot mechanism extending from the first and second plates and operably associated with the pivot mechanism and coaxial therewith for providing a resistant force to pivoting of the first and second plates wherein the first plate is pivoted in a clockwise direction by the toes of one foot of the operator and wherein the second plate is pivoted in a counterclockwise direction by pressure from the anterior aspect of the other foot of the operator so as to cause muscular actions of the foot and/or leg of the operator.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 203 words
A portable foot and/or leg exercising apparatus for an operator, comprising: a base having a support member mounted thereon; pivot means mounted on said support member; a first and second foot plate positioned on opposite sides of said support member; means centrally positioned between said first and second plates and extending vertically from each of said first and second plates pivotally mounting said first and second plates on opposite sides of said support member wherein said pivot means comprises a first hub extending from said first plate and a second hub extending from said second plate; and means disposed surrounding said pivot means and coaxial therewith for resisting respective pivoting of said first and second foot plates wherein said means for resisting respective pivoting comprises a force resistant friction disk mounted on said pivot member and disposed between said first and second hub for frictional engagement therewith; the first plate is pivoted in a clockwise direction by the toe of one foot of the operator; and wherein the second plate is pivoted in a counterclockwise direction by pressure from the anterior aspect of the other foot of the operator so as to cause muscular action of the foot and/or leg of said operator.
Claim 2
Dependent Claim 203 words
A portable foot and/or leg exercising apparatus for an operator, comprising: a base having a support member mounted thereon; pivot means mounted on said support member; a first and second foot plate positioned on opposite sides of said support member; means centrally positioned between said first and second plates and extending vertically from each of said first and second plates pivotally mounting said first and second plates on opposite sides of said support member wherein said pivot means comprises a first hub extending from said first plate and a second hub extending from said second plate; and means disposed surrounding said pivot means and coaxial therewith for resisting respective pivoting of said first and second foot plates wherein said means for resisting respective pivoting comprises a force resistant friction disk mounted on said pivot member and disposed between said first and second hub for frictional engagement therewith; the first plate is pivoted in a clockwise direction by the toe of one foot of the operator; and wherein the second plate is pivoted in a counterclockwise direction by pressure from the anterior aspect of the other foot of the operator so as to cause muscular action of the foot and/or leg of said operator.
Claim 3
Dependent Claim 23 words
An apparatus as set forth in claim 1, wherein said resisting means further comprises at least one elastic band surrounding said pivot member.
Claim 4
Dependent Claim 32 words
An apparatus as set forth in claim 2 wherein said first and second hub each having a plurality of notches formed therein for cooperative engagement with said at least one elastic band.
Claim 5
Dependent Claim 79 words
An apparatus as set forth in claim 1, wherein said resistant disc has a central aperture formed therein and a first and second radially disposed aperture formed therein and wherein said pin member of said first hub is disposed in said first aperture of said resistant disc, said pin member of said second hub is disposed in said second aperture of said resistant disc and said pivot means is positioned in said aperture of said first and second hub.
Claim 6
Dependent Claim 19 words
An apparatus as set forth in claim 4 wherein said radially disposed apertures further comprise radially disposed slotted apertures.
Claim 7
Dependent Claim 276 words
A portable foot and/or leg exercising apparatus for an operator, comprising: a base having a support member mounted thereon; pivot means mounted on said support member; a first and second foot plate positioned on opposite sides of said support member; means centrally positioned between said first and second plates and extending vertically from each of said first and second plates pivotally mounting said first and second plates on opposite sides of said support member wherein said pivot means comprises a first hub extending from said first plate and a second hub extending from said second plate; means disposed surrounding said pivot means and coaxial therewith for resisting respective pivoting of said first and second foot plates wherein said means for resisting respective pivoting comprises a deformable, force resistant disk mounted on said pivot member and disposed between said first and second hub for frictional engagement therewith; the first plate is pivoted in a clockwise direction by the toe of one foot of the operator; and wherein the second plate is pivoted in a counterclockwise direction by pressure from the anterior aspect of the other foot of the operator so as to cause muscular action of the foot and/or leg of said operator; and said first and second hub each have a first and second aperature formed therein, respectively, and a pin member extending therefrom and wherein said pin member of said first hub is positioned in said first aperature of said second hub, said pin member of said second hub is positioned in said first aperature of said first hub and said pivot means is positioned in said second aperature of said first and second hub.
Claim 8
Dependent Claim 276 words
A portable foot and/or leg exercising apparatus for an operator, comprising: a base having a support member mounted thereon; pivot means mounted on said support member; a first and second foot plate positioned on opposite sides of said support member; means centrally positioned between said first and second plates and extending vertically from each of said first and second plates pivotally mounting said first and second plates on opposite sides of said support member wherein said pivot means comprises a first hub extending from said first plate and a second hub extending from said second plate; means disposed surrounding said pivot means and coaxial therewith for resisting respective pivoting of said first and second foot plates wherein said means for resisting respective pivoting comprises a deformable, force resistant disk mounted on said pivot member and disposed between said first and second hub for frictional engagement therewith; the first plate is pivoted in a clockwise direction by the toe of one foot of the operator; and wherein the second plate is pivoted in a counterclockwise direction by pressure from the anterior aspect of the other foot of the operator so as to cause muscular action of the foot and/or leg of said operator; and said first and second hub each have a first and second aperature formed therein, respectively, and a pin member extending therefrom and wherein said pin member of said first hub is positioned in said first aperature of said second hub, said pin member of said second hub is positioned in said first aperature of said first hub and said pivot means is positioned in said second aperature of said first and second hub.
Claim 9
Dependent Claim 75 words
An apparatus as set forth in claim 4, wherein said resistant disk has a central aperature and a first and second radially disposed aperature formed therein and wherein said pin member of said first hub is disposed in said first aperature of said resistant disk, said pin member of said hub is disposed in said second aperature of said resistant disk, and said pivot means is positioned in said central aperature of said resistant disk.
