  • Roller skate braking device
    Patent number: 5655783
    Abstract: A break for an in-line roller skate is disclosed, which is activated by rotating the skater's lower leg rearwardly to drive a friction pad downwardly to engage the skating surface. A locking device permits the friction pad to be locked in a braking position while the skater resumes the normal skating posture for manueuvring. The brake is released by lifting the skater's heel to permit the friction pad to return to a stowed position.
