A sliding assembly includes two pull-out guides which can be secured to opposite side walls and each of which includes a stationary guide rail, a middle rail movably mounted on the guide rail, and a running rail movably mounted on the middle rail. A first slidable element is retained on the two running rails of the two pull-out guides, and a second slidable element is retained on the two middle rails of the two pull-out guides. By moving one slidable element, the other slidable element can also be moved.

A slide rail assembly comprises a first rail, a second rail, a third rail, a blocking element and an engagement element. The first rail has a blocking part. The blocking element is connected to the second rail. When the second rail is located at a retrieve position relative to the first rail, and the engagement element is operatively connected to the blocking element for moving the blocking element from a first predetermined position to a second predetermined position relative to the second rail, only the third rail can move relative to the second rail when the slide rail assembly is extended along an extension direction, in order to adjust extension length of the slide rail assembly.

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 slide rail assembly includes a first rail, a second rail, a first engagement element, and a second engagement element. The first rail includes a first blocking part. The second rail is movably connected to the first rail. The first and second engagement elements are connected to the second rail. When the second rail moves relative to the first rail toward a first position, the first engagement element abuts against the blocking part of the first rail. When the first engagement element is operatively detached from the blocking part of the first rail, the second rail to is able to move relative to the first rail toward a second position from the first position. When the second rail is located at the second position, at least part of the second engagement element is adjacent to the blocking part of the first rail.

A slide rail mechanism includes a slide rail assembly and an auxiliary rail member. The slide rail assembly includes two slide rails. The auxiliary rail member is movably mounted to a first one of the two slide rails. When a second one of the two slide rails is detached from the first one of the two slide rails along an open direction, the auxiliary rail member is able to be moved from a retracted position to a predetermined extended position along the open direction relative to the first one of the two slide rails. The second one of the two slide rails is configured to carry a first carried object, and the auxiliary rail member is configured to carry a second carried object.

A three-section slide rail device includes an outer section, a middle section and an inner section. The middle section includes a middle rail slidably disposed on the outer section, a ball sliding plate slidably disposed on the middle rail, and a leaf spring at one end of the middle rail. The ball sliding plate has a plate body, a synchronizing block and a positioning hole formed on the plate body. The inner section includes an inner rail and a synchronizing actuating member pivotably mounted to the inner rail. The synchronizing actuating member is in an abutting engagement with the synchronizing block during an extended movement of the inner section relative to the middle section to make synchronizing movement of the ball sliding plate with the inner section until the positioning hole of the ball sliding plate is engaged with the leaf spring.

A telescopic rail has first, second, and third rail elements, and a drive device. The first and second rail elements are mounted together such that the first and second rail elements are linearly displaceable relative to one another in and counter to a pull-out direction. The third and second rail elements are mounted together such that the third and second rail elements are linearly displaceable relative to one another. The drive device, mounted on the first rail element, causes a linear movement of the second rail element relative to the first rail element. A traction element, fixed to the first and third rail elements, is guided on the second rail element parallel to the pull-out direction such that a displacement movement of the second rail element relative to the first rail element leads to a displacement movement of the third rail element relative to the second rail element.

A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.

A linear guide system having a first rail element, a second rail element, and a third element. The first rail element and the second rail element are borne such that the first rail element and the second rail element are linearly displaceable in relation to one another in and counter to an extraction direction, and the third element and the first rail element as well as the third element and the second rail element are borne together such that the third element and the first rail element as well as the third element and the second rail element are linearly displaceable in relation to one another in and counter to the extraction direction. The linear guide system in this case additionally includes an electrical conductor.

An adjustment device of a slide rail mechanism includes a base, a driving member and an adjusting member. The adjusting member is arranged on the base. The adjusting member is configured to be adjusted for moving the driving member. The adjustment device can be used with a working member to form an interlock mechanism. The interlock mechanism only allows a rail of one of the slide rail assemblies of the slide rail mechanism to be opened.
