Abstract: A device made in accordance with the present invention provides adequate joint protection for a user when the user is involved in activities wherein the joint is likely to have a limited impact area. This invention provides a joint protection device that is comfortable to wear because it is lightweight; well ventilated; designed to provide easily accommodate movement of the limbs without moving off the joint; and configured not to pinch or “bite” the user's skin. The present invention provides a joint protection device having a two-piece design, wherein an upper portion is pivotally connected to a lower portion with an opening between the portions. The device is removably attached to a user's joint with attachment members that are connected to the device and that wrap around the limb of the user. The device of the present invention does not substantially encompass the joint.

Abstract: A brake for roller skates comprising a simple, lightweight mechanism which multiplies the force exerted by the skater into a substantial braking force. The force is exerted by the skater by pushing downward with the heel, which rotates the boot with respect to the frame of the skate. That force is transmitted with leverage to braking shoes or pads that impinge on brake drums adjacent to the wheels. Adjustment for brake wear is provided by a screw that compensates for the shortening of the brake shoe as normal wear occurs. A detent mechanism locks the boot and frame together during normal skating.
