  • Patent number: 4807893
    Abstract: A roller skate comprises a pair of adjacent rollers which are mounted on a shaft which in turn is mounted on two bracket plates extending downward from an intermediate portion of a pedal plate. A lever is pivotally mounted on the bracket plates above said rollers. The lever has an arched portion which extends over the rollers and has a distal end extending adjacent to the front side of the roller. The lever then extends rearward and holds a brake block substantially below the heel portion of the pedal plate. A spring is employed between the pedal plate and the lever to push the lever against a projection formed on one the bracket so as to prevent the lever from swinging. The skate is put in the braking position when the heel portion is depressed. The skate may further include front rollers substantially below the toe portion of the skate and a front brake block substantially at the front of the toe portion.
