Exercise board having central mounting with multi-level adjustable spacer
First Claim
1. In an exercise device having an upper supported board and a lower spherical sectioned pivot for enabling balanced exercise on the upper supported board over the lower spherical sectioned pivot, the improvement comprising:
- means for adjustable tightening between the spherical sectioned pivot and the upper supported board for permitting attachment of the spherical sectioned pivot to the upper supported board at at least two different heights; and
,a spacer for placement between the spherical sectioned pivot and the upper supported board;
the spacer defining at least two different spherical section receiving surfaces at two differing heights with respect to the upper supported board for enabling the spherical sectioned pivot to be supported at two different heights relative to the upper supported board; and
,each spherical section receiving surface bounded by side restraining portions on either side for locking the pivot at one of the at least two different heights whereby upon adjustable tightening between the upper supported board, the spacer and the spherically sectioned pivot a unitary mass is formed.

Abstract
A wobble board is provided with the capability of varying the height between its sphere section and board. The wobble board includes a board with centrally protruding and downward extending bolt. A sphere section having legs, preferably four in number threads to the bolt. In between the sphere section and board underside, a variable height spacer is utilized. Preferably, the variable height spacer is provided with at least two sets of leg receiving notches. These sets of leg receiving notches are each at differing heights relative to the board. At the same time, the position of the notches within each set is complimentary in position to the legs. In operation, height between the sphere section and board is changed by unthreading the sphere section relative to the board without release of the variable height spacer between the sphere section and board. Unthreading continues until leg access to one set of the variable height notches occurs. Thereafter, the legs and spacer are tightened on the threaded attachment until the sphere section at the legs registers to the notches of one set on the spacer. Tightening continues until the sphere section, spacer, and board are locked in a unitary single piece. Exercise with the adjusted spacing between the sphere section and board can then occur.

5. A process for adjusting an exercise device having an upper supported board and a lower spherical sectioned pivot for enabling balanced exercise on the upper supported board over the lower spherical sectioned pivot, the process comprising the steps of:
-
providing means for adjustable fastening between the spherical sectioned pivot and the upper supported board for permitting attachment of the spherical sectioned pivot to the upper supported board at at least two different heights; providing a spacer for placement between the spherical sectioned pivot and the upper supported board, the spacer defining at least two different spherical section receiving surfaces at two differing heights with respect to the upper supported board for enabling the spherical sectioned pivot to be supported at two different heights relative to the upper supported board, each spherical section receiving surface bounded by side restraining portions on either side for locking the pivot at one of the at least two different heights; orienting the spherical sectioned pivot with respect to the spacer to permit the spacer to hold the spherical sectioned pivot at one elevation with respect to the upper supported board; and
,tightening the means for adjustable fastening so that each spherical section receiving surface bounds the side restraining portions on either side when the upper supported board, the spacer and the spherically sectioned pivot form a unitary mass. - View Dependent Claims (6)
