A drawer guide includes a fixed body; an operation body withdrawable from the fixed body; a base; and a base slit. The base slit includes a linear portion; and a curved portion extending from a front end of the linear portion. The drawer guide includes first and second slides movably coupled to the base; a slide slit penetrating the second slide; a first transfer unit having one end movably coupled to the base slit and the other end inserted in the slide slit; a second transfer unit detachably coupled to the first transfer unit. The second transfer unit moves the first transfer unit to the curved portion from the linear portion when the operation body is moved in the withdrawing direction and vice-versa. The drawer guide includes a spring connecting the base and the first slide; and an attractive power supply unit that supplies a power to the second slide.

An arrangement of a pull-out guide can be fastened to a piece of furniture, and the pull-out guide has a first rail, a second rail that is movably mounted on the first rail, and a rail synchronization device. The rail synchronization device includes a toothed rack connected to the first rail, a toothed wheel meshing with the toothed rack, and a bearing block connected to the second rail. The toothed wheel is rotatably mounted in the bearing block, and a driver for a drawer drive device is connected to the toothed rack of the rail synchronization device.

An engagement assembly, a drawer, and a refrigerator having same. The engagement assembly comprises a first engagement part matching the drawer and a second engagement part matching a refrigerator body; one of the first and second engagement parts is a gear, and the other one is a rack; the rack has a tooth surface that allows the gear to travel; the rack comprises a main rack and an extension rack; when the drawer is in a closed state, the tooth surface has a first stroke length; when the drawer is in an opening process, the extension rack moves to a travel path of the gear so that the tooth surface has a second stroke length; when the drawer is in a closing process, the extension rack is reset; the first stroke length is smaller than the second stroke length. The length of the tooth surface increases in the opening process.

A drawer glide mechanism can include a first elongate guide member, a second elongate guide member, a ball bearing component, a v-notch socket, a release mechanism, and/or a roller support. The first elongate guide member can include a distal end that is configured to fit within an opening in the v-notch socket. The drawer glide mechanism can further include one or more floating members and fixed members. In some cases, the drawer glide mechanism includes a release member configured to facilitate separation of the first and second elongate guide members when actuated and to inhibit or prevent accidental separation of the first and second elongate guide members.

A refrigerator includes a cabinet defining a storage chamber, a drawer door, a motor assembly provided at the storage chamber and configured to provide a driving force that moves the drawer door relative to the storage chamber, and a rack gear assembly provided at the drawer door and having an extendable rack gear. The rack gear includes a fixed rack fixed to the drawer door and a moving rack slidably coupled to the fixed rack. The drawer door includes a drawer part that defines an upwardly open storage space, and a door part that is configured to, based on the drawer door being inserted into the storage chamber, close the storage chamber.
