Title:

SLIDING DEVICE FOR DRAWER

Document Type and Number:

WIPO Patent Application WO/2019/139290

Kind Code:

A1

Abstract:

The present invention relates to a sliding device for a drawer, which mixes and uses a plurality of sliding balls having different tensile strengths, thereby reducing noise when being operated and reinforcing the rigidity thereof. The sliding device for a drawer comprises: a fixed rail fixedly coupled to a main body; a movable rail fixedly coupled to a storage body and slidably movable on the fixed rail; an intermediate rail disposed between the fixed rail and the movable rail so as to guide the sliding movement of the movable rail; and ball assemblies which slidably move by being disposed between the intermediate rail and the fixed rail and between the intermediate rail and the movable rail, and which have a plurality of sliding balls having different tensile strengths, wherein the ball assemblies have sliding balls having a higher tensile strength disposed on the outermost side thereof. Due to said configuration, it is possible to obtain the effects of reducing noise by generally using sliding balls having a lower tensile strength, and reinforcing rigidity by using sliding balls having a higher tensile strength at a region to which an impact load is applied.
