Abstract

An apparatus for aerobic leg exercise of a seated user includes a first unit having means for supporting a first linear track on a floor, means for joining a first unit to the first linear track for non-resistive movement and means for enabling the seated user with a multi-positional contact for moving the first unit along the first linear track without substantial vertical movement of the seated user'"'"'s knee. A second unit has means for supporting a second linear track on the floor, means for joining a second unit to the second linear track for non-resistive movement and means for enabling the seated user with a multi-positional contact for moving the second unit along the second linear track without substantial vertical movement of the seated user'"'"'s knee. A means secures the first unit and the second unit at a desired splay angle and a means stabilizes the apparatus.

Claims

1. An apparatus for aerobic leg exercise of a seated user, the apparatus comprising:

a first unit comprising;

a first I-bar frame comprising a first bar, extending arms at each distal end of said first bar and a first roundhead arm extending from a first side of said first bar proximate a first distal end of said first bar, said first roundhead arm having a rounded portion at a distal end with an aperture disposed in said rounded portion;

end brackets joined to tops of each extending arm;

a first linear track joined to and disposed between said end brackets; and

a first padded unit slidably joined to said first linear track for non-resistive movement between said end brackets, said first padded unit having a generally domed shaped top for enabling the seated user with a multi-positional contact for moving said first padded unit along said first linear track without substantial vertical movement of the seated user'"'"'s knee; and

a second unit comprising;

a second I-bar frame comprising a second bar having a first side generally facing said first roundhead arm, extending arms at each distal end of said second bar and a second roundhead arm extending from said first side of said second bar proximate a first distal end of said second bar, said roundhead arm having a rounded portion at a distal end with a bolt, dimensioned to fit in said aperture, disposed in said rounded portion;

end brackets joined to tops of each extending arm;

a second linear track joined to and disposed between said end brackets; and

a second padded unit slidably joined to said second linear track for non-resistive movement between said end brackets, said second padded unit having a generally domed shaped top for enabling the seated user with a multi-positional contact for moving said second padded unit along said second linear track without substantial vertical movement of the seated user'"'"'s knee.

2. The apparatus as recited in claim 1, wherein said first linear track and said second linear track each comprises at least two linear rods.

3. The apparatus as recited in claim 1, further comprising a plurality of feet joined to bottoms of said extending arms of said first I-bar frame and said second I-bar frame for contacting a floor surface.

4. The apparatus as recited in claim 1, further comprising a threaded attachment cap for securing said first unit and said second unit at a desired splay angle where said bolt is inserted in said aperture and said threaded attachment cap is tightened on said bolt.

5. The apparatus as recited in claim 4, further comprising a stabilizer bar comprising two linear portions rotatably joined at distal ends, said stabilizer bar rotatably joinable to said first I-bar frame and said second I-bar frame.

6. The apparatus as recited in claim 1, wherein dimensions of the apparatus are suitable for placing in an opening under a desk.

7. The apparatus as recited in claim 1, wherein said first padded unit and said second padded unit comprise vinyl covered foam.

8. An apparatus for aerobic leg exercise of a seated user, the apparatus comprising:

a first unit comprising;

a first I-bar frame disposed in a first plane, said first I-bar frame comprising a first bar, extending arms disposed in said first plane at each distal end of said first bar and a first roundhead arm extending along said first plane from a first side of said first bar proximate a first distal end of said first bar, said first roundhead arm having a rounded portion at a distal end with an aperture disposed in said rounded portion;

a plurality of feet joined to bottoms of said extending arms for contacting a floor surface;

end brackets joined to tops of each extending arm portion extending from a second side of said first bar;

a first linear track joined to and disposed between said end brackets, said first linear track comprising at least two linear rods; and

a first padded unit slidably joined to said first linear track for non-resistive movement between said end brackets, said first padded unit having a generally domed shaped top for enabling the seated user with a multi-positional contact for moving said first padded unit along said first linear track without substantial vertical movement of the seated user'"'"'s knee;

a second unit comprising;

a second I-bar frame disposed in said first plane, said second I-bar frame comprising a second bar having a first side generally facing said first roundhead arm, extending arms disposed in said first plane at each distal end of said second bar and a second roundhead arm extending along said first plane from said first side of said second bar proximate a first distal end of said second bar, said roundhead arm having a rounded portion at a distal end with a bolt, dimensioned to fit in said aperture, disposed in said rounded portion;

a plurality of feet joined to bottoms of said extending arms for contacting the floor surface;

end brackets joined to tops of each extending arm;

a second linear track joined to and disposed between said end brackets, said second linear track comprising at least two linear rods; and

a second padded unit slidably joined to said second linear track for non-resistive movement between said end brackets, said second padded unit having a generally domed shaped top for enabling the seated user with a multi-positional contact for moving said second padded unit along said second linear track without substantial vertical movement of the seated user'"'"'s knee;

a threaded attachment cap for securing said first unit and said second unit at a desired splay angle where said bolt is inserted in said aperture and said threaded attachment cap is tightened on said bolt; and

a stabilizer bar comprising two linear portions rotatably joined at distal ends, said stabilizer bar rotatably joinable to said first I-bar frame and said second I-bar frame.

9. The apparatus as recited in claim 8, wherein dimensions of the apparatus are suitable for placing in an opening under a desk.

10. The apparatus as recited in claim 8, wherein said first padded unit and said second padded unit comprise vinyl covered foam.
