Set of pull-out guides for drawers

摘要

A middle rail (7) at each side runs between a supporting rail (5) on the main body and an extension one (6) on the drawer, the load being transmitted by rollers between them. A control roller midway along the middle rail runs against a top rib on the supporting rail and a bottom one on the extension rail. Travel rollers (11) on a truck run against both sides of the top horizontal flange (25) of the middle rail, at whose rear end is a further travel roller supporting it from the supporting rail. At the latter's forward end is a slide guiding the middle rail in the lateral direction. There can be a lengthwise horizontal lug (15) on the middle rail, protruding below the top rib (24) on the supporting rail. The slide can have a vertical slot, in which a vertical rib (26) on the middle rail is guided.
