Abstract: A bicycle brake device which has extremely small brake pads, relatively hard pad rubber, and a tool-free pad adjustment mechanism that allows the rider to periodically extend the pad as it wears. Partially because of the small pad size, the brake can be designed to be very powerful, and simplify initial installation and adjustment. The bicycle rim brake has fewer degrees of freedom of adjustment in order to simplify installation and maintenance. The preferred embodiment can have only four degrees of freedom because the pad surface is so small that a pad rotation adjustment and pad orientation adjustment are unnecessary. The present invention allows the user to easily extend the pads to their original preferred position without tools. This not only keeps the brake pad surface at the correct position relative to the rim, but also keeps the brake hand levers in the preferred position.

Abstract: The present invention implements a releasable wheel mounting mechanism and a dual braking system to provide a wheelchair that transforms from a conventional wheelchair to a companion wheelchair. A set of small rear wheels traditionally found on a companion wheelchair is mounted on the rear of the chair, along with a means for removably mounting a set of large wheels.

With the large wheels mounted on the chair, the chair serves as a conventional wheelchair capable of being steered and propelled by the chair's occupant. To enable the dual nature of the chair, the present invention employs a braking system that allows the chair to be stopped by the occupant in either mode.
