Abstract:
1. A roller skate steering and suspension mechanism, comprising: a base plate having at least one pivot cup mounting hole and at least one kingpin mounting hole; said pivot cup mounting hole having interior sides and a bottom; a pivot cup having a cup body, a cup socket and a cup end disposed opposite said cup socket; said pivot cup positioned to float without direct contact in said pivot cup mounting hole such that said cup socket faces outwards; a radially disposed resilient means for shock absorbing in mechanical communication between a portion of said cup body and a portion of said interior sides, said radially disposed resilient means for shock absorbing providing the functions of retaining said pivot cup within said pivot cup mounting hole, absorbing lateral loads experienced by said pivot cup, and providing lateral movement for said pivot cup in response to lateral loads; an axially disposed resilient means for shock absorbing in mechanical communication between a portion of said cup end and a portion of said bottom; a skate truck having at least one wheel axle holder, a pivot pin socket, and a kingpin aperture; a pivot pin having a pivot pin axis, a proximal end comprising a threaded section and a distal end comprising a rounded pivot; said threaded section being threaded into said pivot pin socket, said rounded pivot in rotary mechanical communication with said cup socket; a kingpin having a kingpin axis, said kingpin being attached into said kingpin mounting hole; said pivot pin axis and said kingpin axis being intersecting; an upper resilient cushion disposed above said truck and a lower resilient cushion disposed below said truck; said kingpin being disposed through said kingpin aperture; and, said upper resilient cushion and said lower resilient cushion being clamped against said skate truck along said kingpin axis, thereby holding said skate truck in a resiliently fixed orientation.
