  • Patent number: 11950695
    Abstract: A slide rail mechanism is configured to be mounted to a first post and a second post of a rack. A transverse space is defined between the first post and the second post. The slide rail mechanism includes a first slide rail kit and a second slide rail kit. Each of the slide rail kits includes a fixed rail and a movable rail longitudinally movable relative to the fixed rail. The two fixed rails are respectively connected to the two posts, and are located outside the transverse space. Each of the fixed rails is formed with a passage corresponding to inside of the transverse space. Each of the movable rail is configured to be movably mounted to the passage.

  • Publication number: 20240068516
    Abstract: A slide rail assembly includes a first rail, a second rail, a slide assisting device, an elastic member and a working member. The second rail and the first rail are movable relative to each other. The elastic member is arranged on the second rail. During a process of the second rail being moved relative to the first rail along an opening direction, the working member is configured to contact the elastic member in an initial state in order to drive the slide assisting device to move along the opening direction to a predetermined position. When the slide assisting device is located at the predetermined position, the elastic member releases an elastic force through a predetermined space of the first rail, such that the elastic member is no longer in the initial state with the working member no longer contacting the elastic member.

  • Publication number: 20240065438
    Abstract: A slide rail assembly is provided and includes a first rail, a second rail movable with respect to the first rail, a working member, an operating member and a blocking member. When the second rail is located at an extended position with respect to the first rail and the working member is in a first state, the working member and a blocking feature of the first rail block each other for restraining the second rail from moving toward a first predetermined direction from the extended position. The blocking member is switchable between a blocking state and a non-blocking state for restraining the operating member from driving the working member to disengage from the first state or for allowing the operating member to drive the working member from the first state to a second state. Besides, a related slide rail kit is also provided.
