摘要： A thin profile drawer slide apparatus for slidably supporting a heavy drawer in furniture, comprising symmetrical, identical channel members for slidably attaching the apparatus to a drawer and an article of furniture, a plurality of bearings slidably retained in the channel members by bearing retainers, and by an intermediate slide member. The intermediate slide member comprises the unitarily formed combination of a generally vertical central wall, a first bearing raceway joined to an end of the central wall, and a second bearing raceway joined to an arcuate wall extending angularly outwardly from the first bearing raceway, whereby the first and second bearing raceways are vertically and angularly separated. The ball bearings are arranged in four linear, slightly offset sets. Use of a single intermediate slide member with raceways for four separate sets of bearings provides a thin, strong drawer slide for carrying heavy loads. In an alternate embodiment, the central wall of the intermediate slide member comprises a generally rectangular window with a progression roller mounted therein on a vertical axis of rotation. The roller exerts friction on the inner faces of the channel members by compression against the inner faces when the roller is moved. Edges of window act as a detent on the roller and also urge the slide closed when the slide is brought to rest with the roller against one of the edges. The windows relieve compression of the roller when the slide is fully closed.
