  • Patent number: 5308093
    Abstract: A skate and skate brake which allows a user to brake the skate smoothly and evenly without catching on a ground surface utilizes a rotatable assembly having a resilient outer circumferential member attached to a relatively hard inner hub, the rotatable assembly brakes the skate by rotating with a rotational friction greater than that of the average rotational friction of the skate wheels. The rotational friction of the rotatable assembly is controlled by locating a non-rotating brake pad in physical contact with the inner hub. The amount of rotational friction can be increase by urging the brake pads against an annular portion of the inner hub and by positioning the brake pads within an interior recess inside the inner hub so that an increase in the downward force that the user applies to the brake increases the force by which the inner hub of the rotatable assembly is urged against the brake pads.
