Abstract

Exercise apparatus with a base plate, a pair of opposed flanges extending perpendicularly from the end and side of the base plate, each the flange having a an aperture that receives a pin that acts as a shaft, an inverted U shaped frame, the ends of the U shaped frame being connected to the shaft pins so that the U shaped frame can rotate about the shaft pins, a plurality of radially spaced apertures in each the flange, a single aperture in each said inverted U shaped frame that aligns with said radially spaced apertures, a pair of connecting pins to retain said inverted U shaped frame to said flanges in a fixed position with respect to said base plate, a foot retaining assembly slidibly mounted in a horizontal manner with respect to the base of said inverted U shaped frame, said foot retaining assembly comprised of a plurality of foot retaining bars attached at each end to a side plate, a pair of retaining pins that can fix said foot retaining assembly higher or lower along said inverted U shaped frame. A preferred embodiment includes wherein a pair of guide rods can be inserted so that they extend horizontally out from said flanges to the front edge of said base plate. A preferred embodiment includes wherein said guide rails can slidably retain a resilient exercise ball in a linear rolling fashion.

Claims

1. Exercise apparatus comprising:

a base plate;

a pair of opposed flanges extending perpendicularly from the end and side of said base plate;

each said flange having a an aperture that receives a pin that acts as a shaft;

an inverted U shaped frame;

the free ends of said U shaped frame being connected to said shaft pins so that said U shaped frame can rotate about said shaft pins;

a plurality of radially spaced apertures in each said flange;

a single aperture in each said inverted U shaped frame that aligns with said radially spaced apertures;

a pair of connecting pins to retain said inverted U shaped frame to said flanges in a fixed position with respect to said base plate;

a foot retaining assembly slidibly mounted in a horizontal manner with respect to the base of said inverted U shaped frame;

said foot retaining assembly comprised of a plurality of foot retaining bars attached at each end to a side plate;

said side plate having a frame retaining connector;

said retaining connector having an aperture that can align with one of a plurality of spaced apertures located in each leg of said inverted U shaped frame;

a pair of retaining pins that can fix said foot retaining assembly higher or lower along said inverted U shaped frame; and

said foot retaining bars being adjustable to allow for different sized feet.

2. Exercise apparatus as claimed in claim 1 wherein a pair of guide rods can be inserted so that they extend horizontally out from said flanges to the front edge of said base plate.

3. Exercise apparatus as claimed in claim 2 wherein said guide rails can slidably retain a resilient exercise ball in a linear rolling fashion.

4. Exercise apparatus as claimed in claim 1 wherein said exercise apparatus can be used in conjunction with an exercise ball to perform a variety of stretching and compression exercises.
