Balance training apparatus
First Claim
1. A balance board adapted for balance training on top of a spherical rolling fulcrum, comprising:
- an upper footstep surface and a lower bearing surface; and
a progressive series of hoop sub-frames adapted for depending from the bearing surface with respect to a common center of geometry and enclosing progressively smaller framed-in areas of the bearing surface, respectively, within progressively smaller framed-in crown-cavities thereby defined, respectively, ranging between extremes of a major sub-frame and a minor sub-frame;
wherein the framed-in area of the bearing surface by the major sub-frame is either flat or domed;
wherein at least all but the major sub-frame are selectively removable from the platform for clearing way for the progressively smaller framed-in crown-cavities; and
whereby selectively utilizing the minor sub-frame over, conversely, exclusion thereof in favor of any of the progressively larger sub-frames, with all relatively smaller sub-frames excluded as well, progressively changes the level of difficulty for trainees standing on the upper footstep surface with the spherical rolling fulcrum crowned by the balance board within the selected sub-frame;
said sub-frames being adapted to permit said spherical rolling fulcrum to roll freely sandwiched between said balance board and a ground surface unless stopped against any portion of any sub-frame.

Abstract
A board for balance training has an upper footstep surface, lower bearing surface and a progressive series of concentric, cylindrical sub-frames depending from the lower surface which enclose progressively smaller framed-in areas of the bearing surface within progressively smaller framed-in crown-cavities defined by each. This progressive series ranges extremes of a major in size to minor, with none, one or more intermediates. All at least but the major sub-frame are selectively removable from the board for clearing way for progressively larger framed-in crown-cavities. Any of the sub-frames permit a training ball to roll freely sandwiched between the board and ground unless stopped against any portion of that sub-frame. Selectively utilizing a minor sub-frame over, conversely, exclusion thereof in favor of any of the progressively larger sub-frames, progressively changes the level of difficulty for trainees standing on the upper footstep surface.

7. A balance board adapted for balance training on top of a spherical rolling fulcrum, comprising:
-
an upper footstep surface; a lower surface provided with a recessed major sub-frame defining a major crown-cavity that exposes a major framed-in area of a bearing surface, which is either flat or domed; and a minor sub-frame comprising a removable insert adapted for depending from the bearing surface within the major sub-frame and enclosing a progressively smaller framed-in area of the bearing surface within a progressively smaller framed-in crown-cavity thereby defined; whereby selectively utilizing the minor sub-frame over, conversely, exclusion thereof progressively changes the level of difficulty for trainees standing on the upper footstep surface with the spherical rolling fulcrum crowned by the balance board platform within the selected sub-frame; said sub-frames being adapted to permit said spherical rolling fulcrum to roll freely sandwiched between said balance board and a ground surface unless stopped against any portion of any sub-frame. - View Dependent Claims (8, 9, 10, 11, 12)
