Abstract
Abstract A progressive, full ball bearing, precision, telescoping slide mechanism for the suspension of drawers having an adaptor attached to the drawer to provide simple attachment without tools to the drawer and to permit the drawer to be easily - without tools - removed from the slide when it is desired to do so, and readily reinserted, or interchanged with other drawers. When the drawer is carried by the usual two slides with the adaptors resting on the slides, there is means for releasably locking the adaptors to the outer slide mechanism for positively securing the drawer in place on the slides. The latching mechanism in one arrangement is manually operated. In another arrangement, the latching mechanism latches automatically. Another feature is a combination of stops which will absorb any metal clicking noise at times of opening or closing of drawer, thus, contributing to the elimination of today''s harmful ''''noise pollution'''' modern office ecology is exposed to. Still another feature comprises means to hold a drawer in the closed position so that a slight forward tilt of the drawer or cabinet will not let the drawer come out as the slides roll very easily. Also, a too forcefully closed drawer has a tendency to come out against, that is, to bounce open. With the present invention, these conditions are overcome.
