초록 ▼

An in-line roller skate is provided having a front bogie that supports a front pair of surface-engaging wheels and a rear bogie that supports a rear pair of surface-engaging wheels. An elongated two-member frame extends vertically down from the underside of the skate shoe and in the horizontal direction of skate movement. The lower end of a front lever-pair pivotally mounts the front bogie, and the lower end of a rear lever-pair pivotally mounts the rear bogie. The front lever-pair inclines downward toward the toe of the shoe, the rear lever-pair inclines downward toward the heel of the shoe, and a generally middle point of each lever-pair is pivoted on the two-member frame. Front and rear shock absorbing mechanisms are provided. The front shock absorbing mechanism functions between the upper end of the front lever-pair and the two-member frame, and the rear shock absorbing mechanism functions between the upper end of the rear lever-pair and the two-member frame. When a shock load is applied to one or both of the front and rear bogies, the associated shock absorbing mechanism absorbs the shock, thus minimizing the shock that is experienced by the shoe. A brake pad is adjustably mounted to the two-member frame at a location adjacent to and above the rear wheel of the rear bogie. When the shoe toe is elevated by the skater, both wheels of the rear bogie remain in physical contact with the skating surface, the rear bogie pivots relative to the rear lever-pair and relative to the shoe sole, and its rear wheel is brought into braking engagement with the brake pad.
