A slide rail includes a first rail, a second rail, and a third rail. The first rail is slidably coupled to the second rail. The second rail is slidably coupled to the third rail. The first rail includes a pulling tab. The second rail includes a first resilient piece and a first clearance slot. The third rail includes a positioning slot. One end of the first resilient piece is fixed to the second rail, and another end of the first resilient piece extends into the first clearance slot. When the first rail slides out, the pulling tab drives the first resilient piece and the second rail to slide out. When the first resilient piece is moved to the positioning slot, the first resilient piece resiliently bends and inserts into the positioning slot, and the first resilient piece is separated from the pulling tab.

A slide rail assembly includes a rail kit. The rail kit includes a rail, a blocking member, and an operating member. The rail has an extension hole. The blocking member is movably disposed on the rail. The operating member is disposed on the rail, can be operated in order to drive the blocking member, and includes an operating portion corresponding to a portion of the extension hole of the rail.

A refrigerator includes a cabinet having a storage space; a door including a door unit to open or close the storage space and a drawer unit to provide a receiving space; rails to connect the door and the cabinet to through which the door is drawn in or out of the cabinet; a driving device disposed at the door unit to provide power; and an elevation device disposed at the drawer unit and connected with the driving device to move up or down at the drawer unit. The driving device includes: a motor assembly; a screw unit including a screw to be rotated by the motor assembly and a screw holder to move up or down along the screw; and a lever to connect the screw holder and the elevation device and rotate when the screw holder moves up or down. The motor assembly includes: a driving motor; and a power transmission unit to transmit power from the motor to the screw unit, and the screw is disposed to be inclined with respect to a vertical line passing in a top-bottom direction of the refrigerator.

A slide rail assembly includes a first rail, a second rail, a third rail and a switch member. The second rail is movably mounted between the first rail and the third rail. The switch member is linearly movable and configured to be switched between a first state and a second state. When the switch member is in the second state, the second rail is configured to be driven by the third rail to move to a predetermined position along a retracting direction. When the third rail is moved relative to the second rail at the predetermined position along an extending direction, the switch member is configured to be switched from the second state to the first state.

A slide rail assembly includes a first rail, a second rail, a first support rail, a second support rail, a third rail, and a third support rail. The second rail is displaceable with respect to the first rail. The first support rail is fixedly connected to a first portion of the second rail. The second support rail is movably connected to a second portion of the second rail. The third rail is fixedly connected to the second support rail. The third support rail is displaceable with respect to the third rail.

Slides provided herein may be configured to support substantial loads while experiencing vibration and shock in the retracted position without degradation of the slide mechanism. An example slide may include: a fixed rail member; a second rail member, a third rail member, where the second rail member is disposed between the fixed rail member and the third rail member, where the second and third rail members translate between an extended position relative to the fixed rail member and a retracted position relative to the fixed rail member; and at least one bearing attached to one of the second rail member or the third rail member, where the at least one bearing is engaged when the second rail member is in the extended position, and disengaged in response to the third rail member being in the retracted position.
