The present invention relates to a refrigerator, and more particularly to a refrigerator including a dual door, which is convenient to use.

In an embodiment, the present invention provides a refrigerator including a body defining a storage compartment therein, a first door hingedly provided at the body so as to open and close the storage compartment, the first door including a door frame having a hinge hole formed therein, and a second door hingedly provided at the first door by means of a hinge, the second door including a lateral side surface, the lateral side surface being at least partially fitted into the door frame, wherein the hinge includes a hinge shaft disposed in the first door so as to define a rotational center of the second door, a hinge bracket coupled to the second door, and an indented member provided between the hinge shaft and the hinge bracket, the indented member being moved through the hinge hole so as to allow the entire second door to escape from the door frame when the second door is opened.

A system of actuating a door includes an actuator for driving an actuating motor of the system, in particular for carrying out an opening or closing movement of the door, a sensor for detecting a state of the system, and a control unit for connecting the actuator and the sensor, the control unit configured to control the system in its totality. The actuator, the sensor, and the control unit are each provided with a communication apparatus, with the plurality of communication apparatus being configured to automatically set up a wireless communication network between one another.

A package delivery system can include an electromechanically operable compartment door installed on a door panel (e.g., garage or front door) at a premises. The system can communicate with a control panel mounted near the door panel, which can be configured to scan package information or receive codes from a delivery person/third party. The control panel can authenticate the package information/codes received from the person before operating the compartment door, providing a secure opening for package delivery. The system can send alerts to the owner of the premises when a package is delivered into the garage. The control panel can store a log of package deliveries and receive package delivery instructions from the premises owner. This package delivery system offers a secure and convenient solution for package delivery, ensuring that packages are delivered safely and efficiently. System lights can indicate the presence of a package within the door panel.

Disclosed is a refrigerator, more particularly a refrigerator including dual doors that are convenient to use. The refrigerator includes a main body having a storage space therein, a first door hinged to the main body for opening and closing the storage space, a door frame provided at the first door, a second door hinged to the first door, the second door having a side wall, at least a portion of which is inserted into the door frame, and a catching part provided in the side wall, and a locking device for selectively allowing the second door to be turned with respect to the first door, wherein the locking device includes a moving member, the displacement of which is changed depending on the open or closed state of the first door, and a catching member, the displacement of which is changed depending on the displacement of the moving member, whereby the protruding length of the catching member from the door frame is changed, the catching member being selectively caught in the catching part.

A motor vehicle door includes a door body and first and second windows carried on that door body. A window drive system independently displaces the first and second windows between closed and opened positions. A related method is also provided.
