Abstract: A slider rail assembly includes a rail member and a bracket. The bracket and the rail member can be displaced with respect to each other. One of the rail member and the bracket is provided with a blocking feature, and the other of the rail member and the bracket is provided with a locking device. When the bracket is at a predetermined position with respect to the rail member and the locking device is in a locking state, the locking device blocks and is blocked by the blocking feature to prevent the bracket from being displaced from the predetermined position in a certain direction.

Abstract: 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.
