Abstract: A brake assembly for applying a braking force to one or more wheels of a wheel supported device, such as an inline skate. The brake assembly has a rotating brake member held by one or more wheels, which is preferably a disk shaped brake, partially embedded on one or both sides of a wheel. A fixed brake member is held so that it does not turn with respect to the wheel frame. The fixed brake member has a friction surface positioned adjacent the braking surface of the rotating member. The fixed brake member can be bent so that its friction surface contacts the rotating brake member to apply a braking force to the rotation of the wheel. Preferably, the fixed brake member is bent by a cam surface and the cam surface is contacted by a movable brake arm held by the frame.

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 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.

Abstract: A wheeled vehicle includes a platform mounted between a front wheel assembly and a rear wheel assembly. The rear wheel assembly includes a speed control assembly that comprises a pedal, a shoe mounted to the pedal and a spring arranged to bias the shoe away from a rear wheel. The pedal is arranged so that a person standing on the platform may press on the pedal with one foot to move the shoe into contact with the real wheel to produce friction for controlling the speed of the wheeled vehicle.

Abstract: A folding chair comprises lower and upper frame sections formed generally as U-shaped members, each having a pair of legs and a central portion between the pair of legs. The ends of the central section are connected to the legs by a pair of curved frame portions curved in planes such that the central frame portions have longitudinal axes displaced away from the legs. The frame sections are preferably formed to be generally identical except that the legs of one frame section may be longer than the legs of the other. The ends of the frame sections are connected together by hinges. A flexible material formed generally as a sling is mounted to the central portions of the upper and lower frame sections to support the weight of a person sitting in the chair. The frame and the hinges the legs cooperate to retain the angle between the upper and lower frame sections at an value determined by the position of the user in the chair.
