Abstract
A standing aid for supporting a person and relieving leg fatigue while standing on a riser step. The standing aid comprises a seat capable of supporting a person standing on the riser step, a vertical stand having a top end secured to the seat and a mounting system secured to a bottom end of the vertical stand. The mounting system has a clamp having a first surface for extending over and in contact with a top surface of the riser step and a second surface for extending below and in contact with a bottom surface of the riser step. The first surface of the mounting system has a relatively small footprint in that it has a second predetermined width which is less than the first predetermined width of the riser step. This small footprint allows people to maneuver around the standing aid while moving on and off the riser step.

A standing aid for supporting a person standing on a riser step, such riser step having a first predetermined width, said standing aid comprising:
- (a) a seat adapted to support a person standing on such riser step;
- (b) a vertical stand having a top end secured to said seat;
- (c) a mounting system secured to a bottom end of said vertical stand, said mounting system comprising a clamp having a first and second opposing surface, said first surface adapted to extend over and into contact with a top surface of such riser step toward a rear edge of said riser step, and said second surface adapted to extend below and into contact with a bottom surface of such riser step, said second surface adapted to be spaced in a transverse direction relative to the riser step from said first surface toward a front edge of said riser step, wherein said top portion has a second predetermined width which is less than such first predetermined width of such riser step;
- and
- (d) a securing member for securing said mounting system about such riser step.
A standing aid for supporting a person standing on a riser step, said standing aid comprising:
- (a) a seat adapted to support a person standing on such riser step;
- (b) a vertical stand having a top end secured to said seat;
- (c) a mounting system secured to a bottom end of said vertical stand, said mounting system comprising a C-shaped member having a first member, second member, and third member, wherein said first member is secured to a bottom of said vertical stand and is adapted to extend above and parallel with respect to such riser step, said second member has a top end portion secured to an end of said first member and is adapted to extend perpendicular with respect to such riser step, and said third member is secured to a bottom end portion of said second member and is adapted to extend below and parallel with respect to such riser step, wherein upon application of said standing aid to such riser step, at least a portion of said second member is adapted to abut a back surface of such riser step and said third member includes at least one spacer secured to a top surface thereof which is adapted to contact said bottom surface of such riser step;
- and
- (d) a securing member comprising a vertically extending holding bar having a first end pivotally secured to said vertical stand and a second end holding a horizontally extending mounting bar, said horizontally extending mounting bar including at least one contact member wherein said holding bar is adapted to be manually pivoted in a downward direction to bring said at least one contact member into contact with such riser step during attachment of said standing aid to such riser step and manually pivoted in an upward direction to disengage said at least one contact member with such riser step during removal of said standing aid from such riser step.
