Disclosed are a guide rail for allowing a drawer to be smoothly opened and closed, and a storage apparatus and a refrigerator having the same. The refrigerator includes a drawer accommodating room; a drawer accommodated in the drawer accommodating room; and a rail configured to guide the drawer to be pulled out of or pushed into the drawer accommodating room. The rail includes a first member extended along pulling-out or pushing-in directions of the drawer and supporting the drawer; a second member extended corresponding to the first member and supported in the drawer accommodating room of the refrigerator; and a plurality of rolling elements arranged between the first member and the second member and being in rolling-contact with the first member and the second member when the drawer is pulled out or pushed in. The second member includes a load support surface having an inward height difference as much as a predetermined gap from a rolling contact surface with which at least one second rolling element different from a first rolling element among the plurality of rolling elements is in rolling-contact so that at least one of the first rolling elements among the plurality of rolling elements is in contact with the first member and the second member and support a load of the drawer in a state that the drawer is positioned in at least one of a critical pull-out section or a critical push-in section. Thus, the refrigerator equally maintains a degree of contact between the rolling element and the members while the guide rail works, thereby uniformizing the operation quality of the guide rail.

A sliding device is disclosed for a drawer capable of reinforcing rigidity while reducing noise during operation by mixing and using a plurality of slide balls having different tensile strengths. The sliding device includes: a fixed rail fastened and fixed to a main body, a movable rail fastened and fixed to a storage body, and sliding on the fixed rail, an intermediate rail disposed between the fixed rail and the movable rail to guide the sliding movement of the movable rail, and ball assemblies disposed between the intermediate rail and the fixed rail and between the intermediate rail and the movable rail, respectively to move to be slidable, and provided with a plurality of slide balls having different tensile strengths, the slide ball having a large tensile strength being disposed at the outermost side thereof.

A three-section linkage drawer slides apparatus, includes an upper rail, a middle rail, a fixed rail, an upper linkage rack, and a lower linkage rack, wherein the middle rail is slidably connected to the fixed rail through the lower linkage rack, the upper rail is slidably connected to the middle rail through the upper linkage rack, the upper linkage rack and the lower linkage rack are of separate structures, the upper linkage rack is mounted between the middle rail and the upper rail after being assembled, and the lower linkage rack is mounted between the fixed rail and the middle rail after being assembled. The upper linkage rack and the lower linkage rack are configured as separate structures, the manufacturing process can thus be simplified, so the manufacturing cost is reduced.

A full extension ball bearing drawer slide assembly comprised of a cabinet rail attached to a cabinet piece, an intermediate rail slidingly engaged with the cabinet rail via bearing runners, a drawer rail slidingly engaged with the intermediate rail via a bearing cage, and a cage hold forward device for advantageously positioning the bearing cage for ease of re-insertion of the drawer rail within the intermediated rail. The cage hold forward device is attached to the intermediate rail and comprises a protrusion for engagement with a flexible trigger mounted on the drawer rail and a flexible clip for releasable engagement with the bearing cage.

The invention concerns a telescopic rail comprising a first rail element with two running surfaces, a second rail element with two running surfaces, at least one rolling body cage for positioning a plurality of rolling bodies. Such telescopic rails are found to suffer from the disadvantage that the rail elements and the rolling body cages all have to be designed to be moveable relative to each other. Accordingly the invention proposes providing a telescopic rail in which the rolling body cage is secured to the first rail element so that the rolling bodies perform a sliding movement with respect to the running surfaces of the first rail element and the rolling bodies perform a sliding movement with respect to the running surfaces of the second rail element or roll on the running surfaces of the second rail element.

A slide rail assembly includes a first rail, a second rail, a slide assisting device, an engaging member and a supporting structure. The slide assisting device is configured to assist in relative movement between the second rail and the first rail. The engaging member and the supporting structure are arranged on the first rail. The second rail is movable from a retraced position along a first direction to be detached from the first rail. When the second rail is moved along the first direction and detached from the first rail, the slide assisting device is moved to be adjacent to the engaging member. During a process of the second rail being moved from a passage entrance of the first rail toward the retracted position along a second direction, the supporting structure is configured to support the second rail, and is extended beyond the engaging member along the first direction.

A slide rail assembly includes a first rail, a second rail, a third rail, a functional member and a movable member. The first rail is movably mounted between the third rail and the second rail. The functional member is arranged on the third rail and includes a positioning part. The movable member is arranged on the first rail and includes an engaging section elastically extended toward the third rail. When the first rail is moved relative to the third rail to an open position, the first rail is configured to be engaged with the positioning part of the functional member through the engaging section of the movable member, in order to hold the first rail at the open position.

A slide rail assembly includes first and second rails, a ball bearing assembly, and a damping device. The first rail has front and rear ends and a middle portion therebetween. The second rail is displaceable with respect to the first rail. The ball bearing assembly is movably mounted between the front and rear ends of the first rail and includes a ball retainer with a plurality of balls and a stopping feature. The damping device is mounted on the middle portion of the first rail to provide a damping force corresponding to the stopping feature of the ball retainer. The ball retainer can be displaced by the second rail such that the stopping feature of the ball retainer contacts the damping device.

An elongate rail (2) for use in a sliding support assembly (1), the sliding support assembly comprising a slide member (3) slidable in a longitudinal direction relative to the elongate rail and first (4a) and second locating assemblies, the elongate rail comprising a channel section defined by a first web, a first flange, and a second flange; a first wall (7a); and a second wall; wherein the first flange and the first wall (7a) define a first channel for retaining the first locating assembly (4a) and the second flange and the second wall define a second channel for retaining the second locating assembly.
