Patent number: 7077487Abstract: 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.Type: GrantFiled: February 24, 2004Date of Patent: July 18, 2006Inventor: Jun-Long Yang

Publication number: 20040174103Abstract: 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.Type: ApplicationFiled: March 7, 2003Publication date: September 9, 2004Inventor: Jun-Long Yang
