  • Patent number: 7367568
    Abstract: A mechanical brake system for inline skates that utilizes all four wheels for braking. The brake is applied by the skater straightening the leg, or both legs if there are brakes on both skates, to a predetermined adjustable position. This causes the adjustable and spring loaded trigger rod, mounted on the pivoting ankle support behind the heel to push the brake lever that extends from behind the heel on both sides of the frame to the front where it is hingedly attached to move downwards. At the mid-point of the skate the brake rail positioned above the wheels and extending the whole length of the skate is connected to the brake lever. The downward movement of the brake lever and brake rail causes the brake rail to contact the wheels causing friction and thereby braking in direct proportion to the force by which the skater is straightening the leg(s). The brake rail is inflexible and shaped to fit the curvature of the wheels thereby facilitating even wheel wear both regarding shape and diameter.

    Abstract: A braking system preferably for an in-line skate includes a brake pad mounted to a forward end of a skate frame and an elevated front wheel attached to the skate frame by two pivot arms. The pivot arms are biased forward which is in a clockwise direction with respect to their pivot point. When skating normally, the pivot arms bias the wheel against the brake pad, but the wheel is elevated from the skating surface and thus the brake is not engaged. When skating in a rearward direction, or desiring a push start, the skater rotates the toe portion of the skate downward and raises the heel. The front wheel will engage the skating surface and the reaction force on the wheel due to friction between it and the skating surface will urge the wheel forward and increase the contact pressure between it and the brake pad.

  • Publication number: 20030107194
    Abstract: A brake assembly for inline skates. The assembly includes a brake arm which is supported by a wheel frame and can be moved between a free running position and a braking position. At least one wheel is a “braking wheel” to which a braking force may be applied. The braking wheel has a brake ring held by the wheel, which ring rotates with the wheel. The brake ring has a radially outwardly facing circular brake contact surface positioned so that it is contacted by the movable brake arm when the movable brake arm is in its braking position. The rotating brake ring preferably has a brake pad surface thereon so that heat generated by the brake passes largely into the movable brake arm, rather than into the rotating brake ring. Preferably, the friction surface between the movable brake arm and the rotating brake ring have mating guide surfaces thereon so that the movable brake arm will be laterally aligned by contact with the rotating brake ring.
