Publication number: 20150189990Abstract: Disclosed herein is a sliding device for guiding a drawer such that the drawer is extended from or retracted into a storage body. The sliding device includes sliding rails each having a pair of flanges, and balls slidably connecting the sliding rails to each other. Each flange includes a raceway in which a portion of the corresponding ball is disposed. The raceway guides the ball such that the ball rolls in a direction of extension or retraction of the drawer. The raceway includes a bent part and support surfaces. The bent part extends parallel to the direction of extension or retraction of the drawer. The bent part is concave in a direction in which the ball is inserted into the raceway. The support surfaces are disposed forming a symmetric structure with respect to an imaginary line connecting a center point of the ball to the bent part.Type: ApplicationFiled: July 18, 2013Publication date: July 9, 2015Inventors: Yoon Sig Park, Dong Hee Lee, Hyun Ho Cha

Publication number: 20150131929Abstract: Disclosed is a drawer sliding device. The drawer sliding device is configured such that when a drawer is pulled out, an intermediate rail and an inner rail are moved together. Therefore, the load support capacity of a drawer slide can be enhanced and the drawer can be smoothly pulled out. The drawer sliding device may be designed such that the intermediate rail can be extended to a position above an operating rail. In this case, the range of the operation of the automatic closing means can be increased without a reduction in the structural strength of the rail. Furthermore, in the present invention, the drawer slide is provided with the automatic closing means. Therefore, when the drawer is retracted to a predetermined range or more, the drawer can be automatically retracted to a completely closed position, and the drawer in the closed state can be prevented from being undesirably opened.Type: ApplicationFiled: April 12, 2013Publication date: May 14, 2015Applicant: SEGOS CO., LTD.Inventors: Yoon sik Park, Hyun ho Cha

Patent number: 8646856Abstract: The present invention relates to a bottom-mounted slide. The bottom-mounted slide includes a movable member, stationary members and a ball housings. First raceways are formed in both lateral sides of the movable member. Each stationary member has second raceways which are respectively connected to the first raceways by corresponding balls to guide the movable member. The balls roll along the corresponding first and second raceways. The ball housings are provided between the movable member and each of the stationary members. The ball housings support the balls. A depressed part is provided in a predetermined portion of each of the lateral sides of the movable member between the corresponding first raceways. The depressed part is inserted into a hollow space defined inside the first raceways of the corresponding end of the movable member. Therefore, the stability can be increased by improvement of roll-forming and reduction of horizontal moment.Type: GrantFiled: July 28, 2009Date of Patent: February 11, 2014Assignee: Segos Co., Ltd.Inventors: Yoon Sik Park, Hyun Ho Cha
