  • Patent number: 5704621
    Abstract: A suspension system for an in-line roller skate in which the suspension system independently controls each wheel of the skate. The suspension system components for each wheel includes a swing arm that is pivotally mounted to a frame attached to a boot of the skate. The wheel is rotatably mounted on a rotation axle between opposing legs of the swing arm. Two C-shaped spring stays are secured to opposing side rails of the frame where one leg of each spring stay travels through a stand-off rigidly secured to one of the opposing legs of the swing arm. A helical spring surrounds the leg of each spring stay between the stand-off and the frame. When the wheel encounters a bump in the ground terrain, the swing arm pivots up and the helical springs are compressed between the stand-off and the frame providing shock absorption. A rebound stop prevents the swing arm from pivoting too far downward. A jounce stop prevents the swing arm from pivoting too far upward.
