Abstract
Abstract Apparatus is disclosed having a circular wobble plate centrally mounted to a base plate via a spherical bearing. A roller assembly is attached about the center mounting point and radially projects intermediate the wobble plate and base plate to create a raised position of one portion of the wobble plate so that weight displacement atop the wobble plate will cause the wobble plate raised position to angularly rotate relative to the base plate.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
145 words
An apparatus for imparting rotating and wobble motion to an operator, comprising: a base member, a board member disposed above said base member and adapted to support an operator standing thereon, shaft means interconnecting said members for rotation and wobble motion of said board member relative to said base member about a predetermined axis of rotation, roller means disposed between and engaging both of said members at a radial position relative to said axis and angularly separating said members, and supporting means for said roller means, said supporting means being mounted for rotation about said axis whereby the impartation of downward force on said board member by the foot of an operator standing thereon causes said board member to rotate and wobble relative to said base member about said axis, further comprising flywheel means attached to said supporting means and rotatable therewith about said axis.
Claim 2
Independent Claim
145 words
An apparatus for imparting rotating and wobble motion to an operator, comprising: a base member, a board member disposed above said base member and adapted to support an operator standing thereon, shaft means interconnecting said members for rotation and wobble motion of said board member relative to said base member about a predetermined axis of rotation, roller means disposed between and engaging both of said members at a radial position relative to said axis and angularly separating said members, and supporting means for said roller means, said supporting means being mounted for rotation about said axis whereby the impartation of downward force on said board member by the foot of an operator standing thereon causes said board member to rotate and wobble relative to said base member about said axis, further comprising flywheel means attached to said supporting means and rotatable therewith about said axis.

Claim 10
Dependent Claim
104 words
The apparatus of claim 1, wherein said roller means includes a first pair of rollers attached to said supporting means and in rotatable contact with said base member: a second pair of rollers pivotally attached to said supporting means and in rotatable contact with said board member, and bushing means connected between said first pair of rollers and said second pair of rollers for dampening the pivotal action therebetween, including a supporting disc interposed between said board member and said base member, said supporting disc engaging and supporting said board member in point contact as said board member rotates and wobbles about said axis.
Claim 11
Dependent Claim
16 words
The apparatus of claim 1, including means for selectively varying the weight of said flywheel means.
Claim 12
Dependent Claim
60 words
The apparatus of claim 1, wherein said roller means includes a first roller attached to said supporting means and in rotatable contact with said base member, and a second roller pivotally attached to said supporting means and in rotatable contact with said board member, and bushing means connected between said first and second rollers for dampening the pivotal action therebetween.
