  • Patent number: 7077487
    Abstract: A drawer rail having an auto-returning device has an outer track, an inner track, a driving block formed on the outer/inner track and a base mounted on the opposite inner/outer track. The base has a spring recess and a block recess with a positioning cutout to respectively receive a spring and a sliding block. The sliding block is pulled by the spring. An elongated through hole is defined in the block recess to allow parts of the sliding block to penetrate to engage with the driving block. When the outer/inner track moves away, the sliding block is pushed by the driving block to bias at the positioning cutout to allow the driving block to release from the sliding block. When the outer/inner track moves near, the driving block urges the sliding block back to a horizontal place and the spring pulls the sliding block back to an original position automatically.

  • Publication number: 20040174103
    Abstract: A undetachable drawer rail includes a U-shaped outer track (10), a U-shaped inner track (20), a bearing race (30), a rail (40) slidably mounted on the inner track (20), a resilient latch (50) secured on the rail (40) and a intermediate stop (60). The inner track (20) has a limit block (21) with a passage attached to the front end. The resilient latch (50) with a V-shaped fork (52) passes through the passage in the limit block (21) by compressing the fork (52), and then the fork (52) returns to its original shape after entering the inner track (20). Thereby, the rail (40) is blocked. Additionally, the outer track (10) further has an inner arrow shaped stub (13) formed toward the inner track (20) to selectively abut the intermediate stop (60) to enhance stability of the undetachable drawer rail.

  • Patent number: 6454372
    Abstract: A drawer rail includes an outer rail fixed to a furniture item, a sliding rail slidably contained in the outer rail, a ball rail slidably contained in the sliding rail, and an inner rail slidably contained in the outer rail and fixed to the drawer or a keyboard supporter. The sliding rail has a front end extending towards an outermost side of the drawer by which it is pulled outward. A positioning device is fixed on the sliding rail near the front end of the sliding rail. The positioning device has a body and a head having a pair of side slopes that are able to respectively engage with a pair of side walls of a groove defined in a bottom of the ball rail. The positioning device of the invention is able to provide a stable positioning effect for the inner rail, and thus the drawer, when the drawer is pulled to an outermost position.
