DETAILED DESCRIPTION OF THE INVENTION

[0008] The tridisc paradigm aids skater balance by eliminating possible confusion as to which is the dominant plane of rolling surface contact for the purposes of balance control, the intrinsic stability of this disc configuration is not effected by variations from set nominal of the disc diameters, that have been caused by uneven disc wear, or the wide range of tolerance limits, to optimize the skaters stability upon the chassis platform, the selection of the rollers' three points of surface contact is critical, as these points define an unambiguous surface of contact triune plane, two rollers must be placed in a line, with their point of contact upon the ambulatory surface wider than the skater's foot gear, so as to produce left to right skeletal stability, as any dimension less will mitigate the afore mention stability, their center line must be located behind the tarsus such that the moment produced by the weight of the skater and the distance between the tarsus and the center of rotation of the disc is always forward toward the third disc, which is located on a line which is equal distance between the two afore mentioned rollers, thus forming the primary contact troika, however the surface contact point of this roller is in front of the (metatarsal/phalangeal of the foot) phalangeal joint, such that the moment produced by the weight of the skater and the distance between the center of rotation of the roller and the phalangeal joint is rearward toward the two afore mentioned rollers, in this methodology the two moments act in concert, at points between the two centers of disc rotation datums, to enhance the skater's mobile stability, deviations from this geometric methodology will adversely impact a skater's ability to maintain mobile stability, the reverse of this methodology may also be employed, i.e. the surface contact points of the two rollers that are located in front of the phalangeal joint of the foot, with a single disc surface contact point located behind the tarsus, however this secondary contract troika arrangement provides intriguing possibilities, with respect the skater's ambulatory abilities, e.g. a skater may choose to have a different tridisc array attached to each foot, giving the skater a choice of four different ambulatory stable disc arrangements, the skater's choice being dictated by which array, or combination array, is a facilitator or inhibitor of which range of complex or routine ambulatory skating maneuvers, for the level of skill for a given skater, thus giving the ability for a skater to customize the disc array for techniques, repertoire and maven level.
