A three-sectional hidden sliding rail includes a pair of sliding rail sub-mechanisms symmetrically mounted at a left and a right side of a movable object. Each sliding rail sub-mechanism includes a fixed guide rail, a middle rail, and a movable guide rail. The fixed guide rail is mounted on a fixed object. The movable guide rail is mounted on a side surface of the movable object. The fixed guide rail and the movable guide rail (3) have a sliding guide groove. An upper and a lower end of the middle rail are mounted in the sliding guide grooves of the movable guide rail and the fixed guide rail. The middle rail is able to slide along the sliding guide groove of the fixed guide rail (1), and the movable guide rail is able to slide along the middle rail (2). The sliding rail sub-mechanisms are connected through a synchronous mechanism.

An embodiment of the present invention provides a sliding device comprising: a first rail member of which one surface is open; a second rail member which slides on the first rail member and of which one surface is open; and one or more ball members which are disposed between the first rail member and the second rail member and are provided as seen on a cross-section, wherein the first rail member and the second rail member are arranged to be engaged with each other through the open surfaces.

A slide unit for a drawer includes a middle slide rail molded through a simple process to enhance productivity. 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 drawer pull-out guide includes a carcass rail to be fixed to a furniture carcass, an extension rail displaceable relative to the carcass rail between a closed position and an open position, and a rolling body and a supporting body movable along a running limb of the carcass rail and a running surface of the extension rail upon a movement of the extension rail. A clearance is formed on the running limb of the carcass rail and/or on the running surface of the extension rail. The rolling body is accommodated within the clearance in the closed position of the extension rail and is thereby relieved from the load of the extension rail so that, in the closed position of the extension rail, the load of the extension rail is carried by the supporting body. Furthermore, rolling body and the supporting body are arranged in a common running carriage.

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.

A slide rail assembly includes a first rail, a second rail, a blocking base, a ball retainer and a blocking member. The second rail is movable relative to the first rail. The blocking base is arranged on the first rail and has a limiting part. The ball retainer is configured to facilitate the second rail to move relative to the first rail. The ball retainer has a contact part. When the blocking member is in a first state, the blocking member is configured to push the contact part of the ball retainer to move the ball retainer in response to a movement of the second rail until the blocking member abuts against the limiting part of the blocking base. When the blocking member is in a second state, the blocking member no longer abuts against the limiting part of the blocking base.

A slide rail assembly includes a first rail, a second rail, a slide-facilitating device, and a retaining member. The second rail is movably mounted in a channel of, and is longitudinally displaceable with respect to, the first rail. The slide-facilitating device is movably mounted between the rails and includes an engaging feature. The retaining member is provided on the first rail and includes an elastic portion with a predetermined feature. The first rail includes a limiting feature for preventing deformation of the elastic portion. When the second rail is moved out of the channel after displacement in an opening direction with respect to the first rail, the slide-facilitating device is at a predetermined position, with the engaging feature engaged with the predetermined feature.

A ball retainer for a slide apparatus and a mold for manufacturing the same. The ball retainer includes, in a width direction, a first extension part and a second extension part that are extended from a center line, forming a pre-determined angle with each other, in a length direction, a body part formed in the center, and a pair of holding parts. Each holding part is respectively formed at each end of the body part. Each holding part includes a plurality of ball insertion grooves for inserting balls that are spaced apart in the length direction. Expansion parts each having an expanding cross-sectional area are respectively formed at both sides in the length direction of the first extension part and the second extension part.

A three-sectional hidden sliding rail, which is able to solve a usage problem influenced by asynchronous sliding rails at two sides of a conventional three-sectional hidden sliding rail during using, includes a pair of sliding rail sub-mechanisms which is symmetrically mounted at a left side and a right side of a movable object. Each sliding rail sub-mechanism includes a fixed guide rail (1), a middle rail (2), and a movable guide rail (3). The fixed guide rail (1) is mounted on a fixed object through a fixed guide rail bracket (4). The movable guide rail (3) is mounted on a side surface of the movable object through a movable guide rail bracket (5). The fixed guide rail (1) and the movable guide rail (3) both have a horizontally parallel sliding guide groove. An upper end and a lower end of the middle rail (2) are respectively mounted in the sliding guide grooves of the movable guide rail (3) and the fixed guide rail (1). The middle rail (2) is able to slide along the sliding guide groove of the fixed guide rail (1), and meanwhile the movable guide rail (3) is able to slide along the middle rail (2). The sliding rail sub-mechanisms at the left side and the right side of the movable object are connected through a synchronous mechanism. The synchronous mechanism includes gear rack mechanisms which are respectively mounted on the sliding rail sub-mechanisms at the left side and the right side of the movable object horizontally and in parallel. The gear rack mechanisms on the sliding rail sub-mechanisms at the left side and the right side of the movable object are connected through a connection shaft (29).

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.
