Publication number: 20070080616Abstract: A sliding guide rail system for slidably opening and closing a drawer within an article of furniture or other equipment, the system comprises a mounting bracket (10) for fixing the system to the article of furniture, a fixed guide (20) mounted on the mounting bracket, an intermediate rail (30) and a pull-out guide (40). The fixed (20) and pull-out guides (40) each have a slidably movable housing, a first slidable housing (50) enabling the intermediate rail (30) to be slidable on the fixed guide (20) and a second slidable housing (50?) enabling the pull-out guide (40) to be in turn slidable on the intermediate rail (30). Each of the fixed guide (20), intermediate rail (30) and pull-out guide (40) have stops (60) disposed thereon for limiting the sliding movement of the first (50) and second slidable housings (50?), wherein a resiliently deformable damping member (52, 52?) is located in a respective chamber (51) provided at each longitudinal end of the first and second slidable housings.Type: ApplicationFiled: September 6, 2006Publication date: April 12, 2007Applicant: Harn Marketing Sdn.

Publication number: 20070057609Abstract: A sliding guide rail assembly is provided for slidably mounting a drawer or equipment within a cabinet or chassis. The rail is formed from a sheet metal into a T-shaped section onto which a sliding means fits and slides smoothly thereon. Guides also formed from a sheet metal into C-sections fitting over the sliding means and operable to slide smoothly therewith. This enables the drawer/equipment mounted on the slide to be drawn in and out with little effort or wear and tear.Type: ApplicationFiled: November 14, 2006Publication date: March 15, 2007Applicant: Harn Marketing Sdn BhdInventors: Harn Lam, Harn Lam

Publication number: 20060279186Abstract: A closing device (10) for a drawer (7) comprising an elongate hollow housing (8) which includes a front portion (8a) and a rear portion (8b), a rotating member (14) slidably mounted in the front portion and a resilient means (9) mounted in the rear portion. The front portion (8a) of the housing (8) comprises first (8c) and second portions (8d) with the first portion having a rotation-preventing internal surface (23) and the second portion having a rotation-admitting internal surface (19). A locking step (22) is defined by the differing internal cross sections of the first and second portions. The rotation of the rotating member (14) in the first portion (8c) is prevented by the internal shape (23) of the first portion relative to the external shape (13) of the rotating member. The rotating member (14) has an angular slot (11) for receiving a guiding pin (16) which is downwardly extending from the bottom surface of a top roller guide (2).Type: ApplicationFiled: May 8, 2006Publication date: December 14, 2006Applicant: Harn Marketing Sdn BhdInventors: Harn Lam, Harn Lam
