The middle slide rail of the slide unit has an improved structure to enable each of a main body-side fixed rail and a drawer-side fixed rail to more smoothly slide on the middle slide rail.

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.

A device for guiding a movable furniture part on a furniture carcass. The device includes a carcass rail arranged on the furniture carcass and a movable rail movable in the opening and closing direction relative to the carcass rail. The carcass rail and the movable rail each have a flat running web and load-transmitting rolling elements are each arranged between a running web of the carcass rail and a running web of the movable rail. During relative movement between the rails, the rolling elements move along the running webs. The running webs are uninterrupted, and the rolling elements between the rails are configured such that, in the mounted state, the running web of the movable rail is always oriented obliquely relative to the running web of the carcass rail.

A three-rows-of-ball bearings sliding rail is disclosed. An inner sliding rail body is supported in outer sliding rail bodies through three rows of support ball bearings which are arranged in parallel in a lengthwise direction of the inner sliding rail body. The three rows of support ball bearings are respectively limited within a length range of the outer sliding rail bodies via ball retainers. Each of the outer sliding rail bodies includes a bottom plate, a first side wall and a second side wall which are respectively located at two sides in a widthwise direction of the bottom plate, are integrally formed with the bottom plate and extended in a lengthwise direction of the bottom plate. The first side wall includes a first arm and a supporting part which is bent inwardly and extends horizontally from a bottom end of the first arm.

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.

Disclosed is a pullout apparatus having side access and designed for simple, adjustable, and accurate installation within a pre-existing cabinet space. The apparatus, slidably mounted within the cabinet space, comprises a top slide assembly mounted to a cabinet carcass and a drawer box. The drawer box is automatically centered on a base slide box. The base slide box is comprised of a slotted template slidingly engaged with a frame, where the frame is mounted to the cabinet carcass. Slide rail assemblies connect the slotted template to the frame. A pin block on the underside of a fixed shelf of the drawer box automatically centers the drawer box on the slotted template. A face plate adjustment mechanism provides for three dimensional alignment of the face plate with surrounding cabinets. An alternate embodiment comprises a mounting bracket providing three dimensional adjustability of the upper drawer slide.

Disclosed herein is a refrigerator. The refrigerator includes a body having a storage compartment therein, a storage body provided to be inserted into or withdrawn from the storage compartment, and a rail device configured to connect the body and the storage body slidingly and to guide insertion and withdrawal of the storage body, wherein the rail device includes a first rail member having a first guider therein, a second rail member slidingly coupled to the first rail member, and a first retainer disposed at an insertion position between the first rail member and the second rail member when the first rail member is inserted into the first retainer and having a first guide protrusion inserted into the first guider movably, formed in the first retainer, and the first guider limits a range of movement in an insertion direction of the first retainer when the first retainer is inserted into the first guider so that the first retainer is located at the insertion position.

A multi-rail concealed slide rail structure includes an outer rail, a first ball retainer, a middle rail, a pair of second ball retainers, and an inner rail. One side of the outer rail is bent inward to form a first track for the first ball retainer to slide thereon. Two side edges of the middle rail are bent in the same direction to form second tracks, respectively. The middle rail is fitted on the first ball retainer, such that the first ball retainer leans against one of the second tracks. The pair of second ball retainers is movably fitted on the middle rail. One side edge of the inner rail is bent inward to form a third track corresponding to the second tracks. The inner rail is fitted on the pair of second ball retainers. Two parallel tracks are provided between the inner rail and the middle rail.

A slide module is disclosed, which comprises an outer rail, a ball rail, a plurality of first balls and a plurality of second balls. The outer rail has a first inner surface and a second inner surface. The ball rail has a first holding section and a second holding section. The first balls are rollably disposed in a plurality of first limiting holes of the first holding section in which the first ball is contacted with the first inner surface and the second holding section and distant from the second inner surface. The second balls are rollably disposed in a plurality of second limiting holes of the second holding section in which the second ball is contacted with the second inner surface and the first holding section and distant from the inner surface. Thereby, the ball rail is capable of moving along the axial direction with respect to the outer rail through the first balls and the second balls.
