A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.

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.

The present invention discloses a refrigerator, comprising a drawer assembly which comprises a first drawer, a first slide rail assembly and a second drawer located below the first drawer, a first recess being disposed on one of the second drawer and the first drawer, and a protrusion being disposed on the other; the first slide rail assembly comprises a guide rail connected in to the cabinet and a slideway disposed on the first drawer, the front end of the slideway being provided with an inclined portion extending obliquely upward from rear to front.

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 defining a storage chamber, a drawer door, a rail assembly that slidably couples the drawer door to the cabinet, a driving device disposed at the door part, and an elevation device disposed at the drawer part to vertically elevate at least a portion of the drawer part. The driving device includes a motor assembly, a pair of screw units, and a pair of levers, each of the pair of levers being coupled to and configured to be rotated by a corresponding one of the pair of screw units to elevate the elevation device. The drawer door includes a door part configured to open and close the storage chamber and a drawer part that is configured to be inserted into and withdrawn out of the storage chamber and defines a storage space.

A slide rail assembly includes a first rail, a second rail, a third rail, and a switching member. The second rail can be displaced with respect to the first rail and is provided with a working feature. The third rail can be displaced with respect to the second rail. The switching member is disposed on the third rail and is configured to contact the working feature when the third rail reaches a predetermined retracted position after being displaced from an extended position in a retracting direction, in order for the third rail to displace the second rail to a predetermined position in the retracting direction via the switching member.
