Disclosed herein is a refrigerator including a cabinet (10) defining a first storage region (2) for storing food, a door (20) opening and closing the first storage region (2) and filled with a thermal insulator therein, a gasket (26) provided on an inner surface of the door (20) and sealing the first storage region (2) from outdoor air by forming a sealing boundary when the door (20) closes the first storage region (2), a first hinge member (40) rotatably connecting the door (2) to the cabinet (10), a container (100) defining a second storage region for storing food and received in the first storage region (2), a second hinge member (200) rotatably connecting the door (20) to the container (100), and a connection member (260) structurally coupled to the second hinge member (200) within the door (20), in order to prevent distortions of a direction and a position of a rotary shaft (206) of the second hinge member (200) relative to a rotary shaft (42) of the first hinge member (40).

The present invention discloses a refrigerator and relates to the technical field of refrigerators. The refrigerator is invented to settle problems, such as increased external space occupied by a refrigerator when its secondary door is opened, increased difficulty in fetching goods in the refrigerator, and heavy loss of cooling capacity resulted from the full opening of an opening. The inventive refrigerator comprises a main door; an opening is formed on a door body of the main door; a guide rail is provided at an edge of the opening, and a secondary door is fitted on the guide rail; and the secondary door is connected with a driving mechanism which can drive the secondary door to slide along the guide rail, and as the secondary door slides along the guide rail, the secondary door can enclose or open the opening. The refrigerator of the present invention is used for preserving and freezing foods.

A building wall module for partitioning a first region from a second region has a frame structure with inner and outer wall panels and lateral fastening devices for connecting the building wall module to a building. In addition, a sliding door system and a secondary door system are integrated in the frame structure, wherein the secondary door system is arranged separated from the sliding door system and can be controlled separately from the control device of the sliding door system. An electrical interface device connects the building wall module to a building system of a building.

A securable pet door is disclosed. The securable pet door may comprise at least one door, at least one knob, one or more windows, at least one frame, and/or at least one hinge. The knob may comprise a latch for secure closing. When the pet door comprises at least one hinge, the hinge(s) may be inserted into at least one hinge recess so that the door may be securely locked via at least one locking mechanism. The different elements of the securable pet door are configured to be oriented in a predetermined, securable, or customizable manner. The door is configured to open from, slide into, revolve within, or move in some other non-limiting equivalent way from or relative to the frame(s).

A personnel access door assembly of an opposing wing of a mine ventilation door. The personnel access door includes a frame including a top portion, a bottom portion, a first post portion and a second post portion, the top frame portion and the bottom frame portion coupled to respective top and bottom ends of the first post and second post portions. The personnel access door further includes sets of trolley wheels affixed to the top or bottom of the frame to engage a top rail or bottom rail affixed on the opposing wing.

A pet access control system according to various aspects of the present technology may comprise a door unit interoperable with a security panel holder. The door unit covers a passage through a structure, such as through the wall or door of a building. The door unit may include a connector that may be mounted on a legacy security panel holder or a dedicated mounting system for the door unit. The door unit may operate in conjunction with a pet identification system to automatically identify and grant access only to authorized pets. In various embodiments, the door unit may be controlled remotely, such as via a web browser on a remote computer or an app running on a smartphone.

A door assembly may include a first sidelite configured to be operably coupled to a first doorjamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and define a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, a first partial door panel, and a second partial door panel. The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.
