Telescopic rail with locking mechanism

Abstract

A telescopic rail mainly consisting of three, substantially C-shaped sections of which the inner or drawer section (3) is slidably mounted in the intermediate section (2) with interposition of a first ball cage and the intermediate section (2) is slidably mounted in the outer or cabinet section (1) with interposition of a second ball cage (7). Mounted at one end of the intermediate section (2) is a stop block (5) with resilient fingers (13) which can be brought into a coupling position wherein the inner section (3) is coupled to the intermediate section (2) and into a pass position wherein the inner section (3) can move independently of the intermediate section (2). The inner section (3) at one end thereof is provided with inwardly pointing projections (11) facing each other, which can cooperate with outwardlly pointing projections (12) facing away from each other, provided on the resilient fingers (13) of the stop block (5), which projections (12) in the coupled position of the sections are disposed in the path of travel of the projections (11) of the inner section (3). Arranged between the free ends of the resilient fingers (13) is a locking member (6) which can be moved in the axial direction of the telescopic rail.
