US Patent 9629459 Slide rail assembly

A slide rail assembly includes a first rail, a second rail, an engaging member, and an operation member. The first rail includes a blocking feature. The second rail is movably connected to the first rail and can be longitudinally displaced from a retracted position to a first extended position and a second extended position relative to the first rail. The engaging member is attached to the second rail. The operation member is mounted to at least one of the first rail and the second rail. The operation member is used to operate the engaging member so that the engaging member is blocked by the blocking feature of the first rail and thus keeps the second rail at the first extended position.
