A slide unit includes a fixed rail fixed to a main body, and provided with a first accommodation space, a movable rail connected to a drawer body to allow the drawer body to be pulled out from and pushed into the main body, provided with a second accommodation space, and configured to be movable with respect to the fixed rail, an inner rail configured such that a first end thereof is inserted in the first accommodation space and a second end thereof is inserted in the second accommodation space, so as to allow the movable rail to be slidable with respect to the fixed rail, and a plurality of slide balls inserted in the first accommodation space to be disposed between the fixed rail and the inner rail, and inserted in the second accommodation space to be disposed between the movable rail and the inner rail.

The present invention shows a telescopic rail having at least one inner, middle, and outer rail element, wherein the inner and outer rail elements are each longitudinally displaceably supported at the middle rail element over rolling members that are guided in a rolling member cage. Provision is made in accordance with a first aspect that the rail elements are mechanically force-coupled via a rail synchronization arrangement such that on a longitudinal displacement of the outer rail element with respect to the inner rail element, the middle rail element is longitudinally displaced with respect to both the inner rail element and the outer rail element. Provision is made in accordance with a second aspect that at least one rolling member cage, and preferably both rolling member cages, is/are mechanically force-coupled to at least one of the rail elements via a respective rolling member cage synchronization arrangement such that a longitudinal displacement of the middle rail element with respect to the inner or outer rail elements results in a longitudinal displacement of the corresponding rolling member cage with respect to the middle rail element.

The present invention relates to a slide device in which retainers provided between an outer rail, an intermediate rail, and an inner rail are guided to be placed at right positions when a drawer is opened or closed, thereby inducing a smooth movements of the rails. According to the slide device of the present invention, openings (312a and 130a) are formed at least in a second retainer locking step (312) and a second retainer deviation prevention step (130), respectively.

A drawer glide mechanism can include a first elongate guide member, a second elongate glide member, a ball bearing component, and a v-notch socket. The first elongate guide member includes a distal end that is configured to fit within an opening in the v-notch socket. The drawer glide mechanism can further include one or more floating members and fixed members.

A drawer slide, having a plurality of slide members is provided. The slide members have a first elongate linear member and a second elongate linear member to slide within a channel defined by an interior surface of the first slide member. The first and second slide members each have a first end portion, a second end portion, and the interior surface defining the first and second channels, respectively. The first slide member is milled from a single piece of material and includes a wall located transversely across the second end portion. Preferably, the interior side edges of the first linear member and the exterior side edges of the immediate linear member further define a first pair of raceways within which a plurality of ball bearings and bearing spacers are alternately disposed to provide a smooth slide motion of the second slide member. The noise damper is a noise-absorbing cushion mounted to the interior surface of the second linear member at the second end portion thereof.

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 slide rail assembly includes a first rail, a second rail and a slide assisting device. The first rail is arranged with an engaging part. The slide assisting device is movably mounted between the first rail and the second rail. The slide assisting device includes a main body, a plurality of slide assisting members and a fastening member. The plurality of slide assisting members are arranged on the main body and configured to contact the first rail and the second rail in a rolling manner. The fastening member is movably mounted to the main body. The second rail is movable relative to the first rail from a retracted position to an extension position along a direction. When the second rail is moved from the extension position along the direction, the slide assisting device is engaged with the engaging part of the first rail through the fastening member.

A drawer guide for guiding a drawer which is extendable out of a carcass in an extension direction is provided with a guidance unit configured as a vertical guidance unit and a guidance unit configured as a lateral guidance unit. The two guidance units each comprise a carcass-side guidance rail and a drawer-side guidance unit mounted on rolling bodies. The two guidance units are coupled to each other by a coupling device.

A slide rail assembly includes a first rail, a second rail, a first slide-aiding device and a second slide-aiding device. The second rail is displaceable relative to the first rail. The first slide-aiding device and the second slide-aiding device are arranged at the first rail. When the second rail is located at a retracted position relative to the first rail, the first slide-aiding device and the second slide-aiding device are configured to support the second rail.
