Lever arm-inclined plane-wheel/axle-inertial/frictional resistance-gravitational exercise apparatus

1 . Exercise apparatus comprising

(a) a tire having an outer diameter and first and second opposed sides;

(b) support apparatus contacting and upwardly depending from the ground and comprising

(i) a generally horizontally oriented base contacting the ground, and

(ii) first and second arms

pivotally connected to and upwardly extending from said base,

spaced apart a selected distance greater than said diameter of said tire,

each having first and second ends,

(iii) a third arm with

a first end pivotally connected to said first end of said first arm, and

a second end pivotally connected to said first side of said tire,

(iv) a fourth arm with

a first end pivotally connected to said first end of said second arm, and

a second end pivotally connected to said second side of said tire,

said support apparatus and said ground having a support apparatus-ground interface;

said support apparatus being shaped and dimensioned such that said tire is movable between at least three operative positions

(c) a first operative position in which

(i) said tire is generally horizontally oriented with respect to the ground,

(i) said third arm is generally vertically oriented, and

(ii) said first arm is canted with

said first end of said first arm spaced apart from and positioned above said tire, and

said second end of said first arm positioned below said first end of said third arm and first end of said first arm,

(iii) said tire is

generally horizontally oriented with respect to the ground,

positioned between said third and fourth arms,

positioned beneath said first and second arms, and

not positioned between said first and second arms,

(d) a second operative position in which

(i) said first arm pivots upwardly to a first generally vertical orientation,

(ii) said third and fourth arms move upwardly to a first generally vertical orientation,

(iii) said tire is

canted in a first direction and generally vertically oriented with respect to the ground,

pivoted about a fulcrum comprising the ground,

positioned between said third and fourth arms,

positioned forwardly from said first and second arms, and

not positioned between said first and second arms,

(e) a third operative position in which

(i) said first and second arms pivot to a second generally vertical orientation,

(ii) said third and fourth arms pivot between said first and second arms to a second generally vertical orientation,

(iii) said tire is

canted in a second direction opposite said first direction,

generally vertically oriented with respect to the ground,

positioned between said third and fourth arms, and

positioned between said first and second arms.
