Abstract

An isometric exercise bar having a base and a pair of substantially triangular planar uprights mounted on opposite sides of the base. The tops of the uprights are connected by a tie bar. A plurality of apertures runs along the forward and rearward edges of the uprights. A second bar is adjustably positioned between the uprights within an aligned pair of apertures.

Claims

1. An isometric exercise growth bar comprising:

a substantially rectangular base plate having a first side and a second side;

a first upright member having a substantially triangular, planar shape, said first upright member having a forward edge, a rearward edge, a top edge, and a bottom edge, with said bottom edge being orthogonally coupled to said base plate at said first side of said base plate, said first upright member further having a plurality of forward edge apertures extending through said first upright member and positioned proximate said forward edge, and a plurality of rearward edge apertures extending through said first upright member and positioned proximate said rearward edge;

a second uprights member having a substantially triangular, planar shape, said first upright member having a forward edge, a rearward edge, a top edge, and a bottom edge, with said bottom edge being orthogonally coupled to said base plate at said second side of said base plate, said second upright member further having a plurality of forward edge apertures extending through said first upright member and positioned proximate said forward edge, and a plurality of rearward edge apertures extending through said second upright member and positioned proximate said rearward edge, said forward edge apertures of said first upright member being aligned with said forward edge apertures of said second upright member and said rearward edge apertures of said first upright member being aligned within said rearward edge apertures of said second upright member;

a substantially cylindrically shaped linear tie bar having a center portion, and first and second ends, said tie bar extending between said first upright member and said second upright member, said tie bar being coupled at said first ends thereof to said upright members proximate said top edges thereof;

a first hand grip mounted concentrically about said center portion of said tie bar to cover said center portion of said tie bar;

a second hand grip mounted concentrically about a first portion of said tie bar positioned between said center portion and said first end of said tie bar to cover said first portion, said second hand grip being spaced from said first hand grip so as to expose a second portion of said tie bar;

a third hand grip mounted concentrically about a third portion of said tie bar positioned between said center portion and said second end of said tie bar to cover said third portion, said third hand grip being spaced from said first hand grip so as to expose a fourth portion of said tie bar;

and,

a bar member removably positioned within an individual one of said plurality of apertures of said first upright member and an individual one of said plurality of apertures of said second upright member;

wherein only said tie bar, said base plate, and said bar member extend between said upright members such that an individual can stand on said base plate between said first upright member and said second upright member to grasp said bar member and said tie bar.

2. An isometric exercise growth bar as recited in claim 1, and further comprising a non skid surface coupled to said base plate.
