  • Patent number: 4974912
    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.

  • Patent number: 4696582
    Abstract: An improved three member drawer slide having a drawer slide, an intermediate member and a cabinet slide. The three member slide moves sequentially so that the cabinet slide extends completely before the drawer slide begins its extension. This sequential movement extends the life of the three member slide. The sequential movement is brought about by a releasable gripping action between the drawer member and the intermediate member.
