A versatile door system for an aircraft includes forward and aft door assemblies. The forward door assembly includes a forward hingeable door hingeably coupled to the airframe proximate a forward location of an aircraft opening and a forward slidable door slidably coupled to the forward hingeable door. The aft door assembly includes an aft hingeable door hingeably coupled to the airframe proximate an aft location of the aircraft opening and an aft slidable door slidably coupled to the aft hingeable door. In a closed configuration, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are securably disposed within the aircraft opening. In operation, the forward hingeable door, the forward slidable door, the aft hingeable door and the aft slidable door are individually operable to collectively provide access to a selectable width of the aircraft opening.

A heating appliance includes an appliance cabinet having a plurality of sidewalls that defining a heating cavity. A door is operably connected to at least one of the sidewalls and operable between open and closed positions. A vertical translating assembly extends from the appliance cabinet to the door. The vertical translating assembly includes drive and offset arms and a power assist mechanism in operable communication with the drive arm. The power assist mechanism at least partially operates the door between the open and closed positions.

Door operator systems are described herein that include the use of an adaptor. It should be understood that the adaptor may be utilized in order to operatively couple separate door operator assemblies together in a double door operator system. The adaptor may include control components (e.g., switches, buttons, toggles, levers, or the like) that are used to turn the door operator system on and off. While the adaptor may be used to operatively couple two separate door operator assemblies together to form a double door operator system, the adaptor may also be used within a single door operator system. Furthermore, with respect to double door operator systems, the system may also utilize a back plate assembly comprising two or more separate back plates (e.g., two or more back plate portions).

A sliding apparatus for a sliding door comprises: a front top roller part including an upper outer bracket and an upper inner bracket; a front bottom roller part including a lower outer bracket and a lower inner bracket which are fitted and fixed to both lower ends of the front door while being connected to each other by a lower connecting bar, and are formed to slide in both lateral directions after moving forward; a rear roller part including rear outer brackets and rear inner brackets which are formed at both upper ends and both lower ends of a rear door formed on one side of the front door, so as to slide the rear door; a front rail part including guide rails which are formed on the upper and lower end surfaces of a rear door frame and the upper and lower surfaces of the rear inner bracket.

A twin louver bank window assembly for efficient thermal control, the assembly including an assembly surround frame including a head member, a sill member and at least a pair of opposed side channel members and a pair of louver banks mounted relative to the assembly surround frame, each louver bank including a number of louvers, one louver bank located towards an outer side of the assembly surround frame and one louver bank located toward an inner side of the assembly surround frame.

The present invention is a power window sync switch for the windows of a vehicle that permits controlling all windows by a single active home or main control window switch. It permits the driver to move all window panels in the vehicle to the same position at the same time. The power window sync switch sends a signal to a micro-processor within the switch to indicate that the window position selected via the actuated switch is to be applied to all window panels simultaneously. The micro-processor within the switch may then proceed to actuate all window lift motors within the vehicle, causing movement of all window panels to the appropriate positions.

The present invention relates to a refrigerator that allows a user to easily open a door thereof. A refrigerator, according to one embodiment of the present invention, may comprise: a cabinet having a storage compartment; left and right doors for opening and closing the storage compartment from the left and right; a door opening module provided to open the left and right doors; and having a single motor provided to rotate forward and backward; and a control unit for controlling forward and backward driving of the single motor, wherein the door opening module comprises: left and right racks provided to be moved by driving of the single motor so as to respectively open the left and right doors; a power transmission device for selectively transmitting a driving force of the single motor to the left and 4right racks; and a single switch provided to be turned on/off in conjunction with the power transmission device, and wherein the control unit detects a current position of the left and right racks through the switching-on/off of the single switch, and controls the forward and backward driving and stopping of the single motor.

A vehicle door includes a door panel slidably operable between a secured position within a door aperture and a staging position partially distal from the door aperture. A latch is engaged with a striker path during operation of the door panel between the secured and staging positions, and is selectively disengaged from the striker path to define open and closed positions of the door panel when the door panel is in the staging position.

A secure passageway is described where a subject is required to pass through two or more chambers in order to travel between two areas, typically where one area is secure and the other is not. For a passageway including first and second chambers, three electronically controlled doorways are included: one between the two chambers; one between a first chamber and a first area; and one between the second chamber and a second area. Sensors are included to determine how many subjects have entered a chamber. Sensors are also included to determine if a subject represents a threat. Subjects determined to represent a threat may be detained or encouraged to reverse direction and exit the passageway through the door where they entered. When a subject is determined to represent a threat, an alarm is optionally sounded.
