Abstract: The clipless bicycle pedal system includes two cylinders, one on the bicyclist's shoe, the other on the pedal, which closely interfit with one another, one member having laterally projecting pins, the other including circumferential slots for receiving the laterally projecting pins, there being cam means to assist in interfitting the two members by pressing them together and to permit their separation by rotational movement of one member relative to the other.

Abstract: A pocket door suspension system which permits the door to be moved, without skewing or sagging, from a closed position to an open and retracted position adjacent a supporting wall, the system having two telescoping slide assemblies mounted to the supporting wall, the door being attached by hinges to moveable members of the slide assemblies. Two cables are provided, each attached at one end to the back end of one fixed slide member and at the other end to the front end of the other fixed slide member. Each cable is slideably attached to the moveable members of the slide assemblies such that the pair of cables trace an "I" figure, the pair of cables effectively preventing the moveable members of the slide assemblies from moving out of a predetermined relationship to each other.
