A slide rail assembly includes an inner rail, a middle rail slidably coupled to the inner rail, and an outer rail slidably coupled to the middle rail. The inner rail includes a first body and a latching member. The latching member extends from the first body to the middle rail. The middle rail includes a second body and a locking device. The locking device is fixedly coupled to the second body. The locking device defines a latching hole configured to receive the latching member so that the middle rail moves together with the inner rail relative to the outer rail to extend to a designated position and length of the slide rail assembly.

A drive device includes a carrier extending in the closing direction of a moveable furniture part, an ejection device for ejecting the moveable furniture part into an open position, and a locking device for locking the ejection device in a locked position. The locking device has a locking pin connected to the ejection device and a guide track for the locking pin formed in or on the carrier, and a synchronization device for synchronizing the movement of the drive device with a second drive device. The synchronization device has a transmission element moveably mounted on the carrier to be moved by the locking pin, and a synchronization coupling element connected to the transmission element. The guide track has a maximum guide track width measured perpendicular to the closing direction, and the synchronization coupling element and the ejection force store are arranged within this guide track width in the closing direction.

An arrangement includes a drawer pull-out guide and a locking device for releasably locking a furniture part. The drawer pull-out guide includes a carcass rail to be fixed to a furniture carcass and an extension rail, the extension rail being displaceably supported between a fully closed position and a fully open position. The locking device includes a first locking component to be fixed to the furniture carcass, and a second locking component to be fixed to the extendably-supported furniture part. The first locking component and the second locking component can be releasably locked together, and the second locking component includes a base member and a locking element for releasably locking the first locking component. The locking element is pivotally supported on the base member, and the extension rail of the drawer pull-out guide can be releasably locked by the locking device in or immediately before the fully open position.

A slide rail assembly includes a first rail, a second rail, a third rail, a synchronization device and a contact feature. The second rail is displaceable relative to the first rail. The third rail is displaceable relative to the second rail. The synchronization device is arranged on one of the second rail and the third rail. The contact feature is arranged on the other of the second rail and the third rail. The third rail and the second rail can synchronously displace relative to the first rail through the collaboration between the synchronization device and the contact feature.

A drive device includes a carrier, an ejection device for ejecting a moveable furniture part out of a closed position, and a locking device for locking the ejection device in the locked position. The locking device has a locking pin connected to the ejection device and a guide track for the locking pin in or on the carrier. The locking pin is locked in an engaging recess of the guide track in the locked position, and a synchronization device is movable relative to the carrier for synchronizing the movement of the drive device with a second drive device. The synchronization device has a transmission element to be moved by the locking pin. The transmission element remains still with the overpressure movement, can be moved by the locking pin during opening movement, can be moved by the locking pin during closing movement, and is linearly moveably mounted on the carrier.
