A guide rail
system for slidably opening and closing a drawer within an
enclosure is disclosed. The
system comprises a mounting bracket for fixing the
system to the
enclosure, the mounting bracket having a fixed rail for receiving an intermediate rail capable of sliding back and forth on the fixed rail, and a pull out rail operatively attached to the drawer and capable of sliding back and forth on the intermediate rail. A resiliently compressible damping device, channel guide with sliding member and a closing device are disposed along the mounting bracket. The pull out rail has a guiding pin on its bottom surface. The sliding member is adapted to travel along the channel guide and locate an end of the damping device that can be pushed inwardly to provide damping. The closing device comprises a housing, a resilient means, and a driver pivotally mounted with the housing and operatively connected to the resilient means. The driver is pivotable between a first locked position and a second linearly moveable position, and includes an angular slot for receiving the guiding pin and an
abutment projection contactable with the sliding member. During a closing action, the pull out rail is caused to slide in a drawer-closing direction. When the guiding pin reaches and engages with the angular slot, the action of the guiding pin within the angular slot causes the driver to be pivoted from its first position to its second position where the
abutment projection engages with the sliding member. Thereafter, linear movement of the driver urges the sliding member to correspondingly travel along the channel guide against the resilience of the damping device, resulting in deceleration of the closing motion.
