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.

The present disclosure relates to an air tight door including a frame having three frame members disposed, respectively, at a first lateral side, a second lateral side, and an upper side of an opening; and a longitudinal member disposed at a lower side of the opening. The door is rotatably connected to the frame member disposed at the first lateral side of the opening so as to open and/or close the opening. A first sealing disposed at each of the three frame members closely contacts the door in a closed state; and a second sealing elevatably disposed at a lower end of the door descends from the lower end of the door to closely contact the longitudinal member in the closed state. A locking device fixes a position of the door in the closed state; and an actuating device is configured to unlock the locking device.

Example aspects of a shear plate for a window frame assembly, a window frame assembly, and a method for insulating a window frame assembly are disclosed. The shear plate for a window frame assembly can comprise a shear plate body defining an outer shear plate surface and an inner shear plate surface, the shear plate body defining a first end, a second end opposite the first end, and a pair of lateral sides extending between the first end and the second end; and at least one pair of shear plate holes extending from the outer shear plate surface to the inner shear plate surface, the pair of shear plate holes oriented such that a line running through a center of the pair of shear plate holes is substantially parallel to the first end and the second end.

A fenestration hinge assembly includes a first leaf rotatably coupled with a second leaf. The first and second leaves each include one or more leaf knuckles. The first and second leaf knuckles are at least partially received within a hinge cavity of a recessed escutcheon, the recessed escutcheon configured for recessed installation within a panel or frame of a fenestration assembly. The fenestration hinge assembly includes a lateral adjustment plate movably coupled with a remainder of the second leaf. The lateral adjustment plate is configured to position at least a portion of the second leaf laterally relative to one of the frame or the panel. The fenestration hinge assembly includes an adjustable hinge configured for elevation adjustment. The adjustable hinge includes an elevation adjustment pin interconnecting the first and second leaf knuckles. The elevation adjustment pin is configured to position the second leaf vertically relative to the first leaf.

A saloon-type door assembly that includes left and right door assemblies that each include a frame adapter having a curved inner surface with a first apex, a front portion and a rear portion, a door adapter that includes a curved outer surface with a second apex a front portion and a rear portion, a door panel associated with the door adapter, at least one front hinge strip secured along a front hinge strip path, and at least one rear hinge strip that is secured along a rear hinge strip path. The front hinge strip path extends from the front portion of the curved outer surface of the door adapter to the rear portion of the curved inner surface of the frame adapter. The rear hinge strip path extends from the rear portion of the curved outer surface of the door adapter to the front portion of the curved inner surface of the frame adapter. The door panels are movable between a front open position, a closed position and a rear open position.

A door, such as a storm door, has modular components for attaching the door to a door frame primary door and for ornamental and functional customization of the storm door and primary door in a convenient manner. A secondary door can be attached to a primary frame of a primary door. At least one anchor mechanism includes a post element attached to the primary frame and an anchor that can be selectively attached to the post element, wherein the anchor includes at least one of and ornamental and a functional element. A secondary door includes a secondary frame, at least one door slab, and at least one hinge coupling the at least one door slab to the secondary frame. A least one hole is formed in the secondary from so that the post element of the anchor mechanism can extend through the at least one hole and the anchor can be attached to the post element to secure the secondary door to the primary frame. The anchor also can be attached to the post when the secondary door is not secured to the primary frame.
