A hinge for the rotatable movement of a door or a similar closing element anchored to a wall or a similar stationary support includes a fixed element adapted to be coupled to the wall or a similar stationary support and a movable element adapted to be coupled to the door or a similar closing element. The fixed and movable elements are coupled to mutually rotate around a first longitudinal axis between an open position and a closed position.

A sliding window assembly includes a frame with a track, and a sliding window portion disposed in the frame and displaceable in the track between a closed position and an open position. The sliding window portion includes a handle pivotable between a lock position and a slide position, and a driving pin coupled with the handle and engaging the track. The driving pin defines a pivot axis for the handle. A guide pin spaced from the driving pin is selectively engageable with the track when the handle is pivoted from the lock position to the slide position. With the handle in the slide position, the sliding window portion is displaceable from its closed position to an open position.

A frame assembly, for use in window and door applications configured to retain a panel, comprising a frame with a cover assembly and a support assembly having a track assembly, and a sill assembly and a header assembly both interconnected to a securing surface. The cover assembly is interconnected to the support assembly. The sill assembly comprises a roller member disposed in supporting relation to the track assembly, and the header assembly is disposed in supporting relation to the support assembly so that the frame is movable relative to both the header assembly and the sill assembly. At least a portion of the frame comprises a predetermined thickness and a predetermined width. The predetermined thickness is substantially less than the predetermined width so that both cooperatively and concurrently enhance viewing through the panel and the frame's stability.

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.

A threshold sealing system for a door panel assembly includes a threshold biasing element and an anchor. The threshold biasing element including a base configured to attach to a floor surface and a biasing surface extending at an oblique angle relative to the base. The anchor is configured to secure the base of the threshold biasing element to the floor. The anchor and the threshold biasing element may be integrally formed and include the same materials. The oblique angle of the biasing surface ranges from 70 degrees to 80 degrees and has a height of at least 1.5 inches.

The present application relates to the field of refrigeration, and provides door assembly and refrigeration equipment. The door assembly includes: a door leaf, including a first door body and a second door body, where the first door body is configured to be rotatably connected to an installation part, and the second door body is configured to move toward an opening side or a hinged side of the first door body with respect to the first door body to switch between a sealing position and an avoidance position; the door leaf is configured to switch between a closing state in which the second door body is in the sealing position and an opening state; the second door body is in the avoidance position when the door leaf is switched between the closing state and the opening state. When the door leaf is in a closing state, the second door body is in the sealing position to ensure the sealing effect of the door leaf. When the door leaf needs to be opened or closed, the second door body is in the avoidance position to prevent the movement of the door leaf from being interfered. When the door assembly is applied to a refrigerator, the dependence of a traditional refrigerator on a flipping beam can be changed, and the defect of inflexible division of storage space of a box body can be avoided.

The present invention relates to a door hinge system (10) for a pivoting door (30) of a domestic appliance (20), in particular for a pivoting oven door (30) of a cooking oven (20). The door hinge system (10) comprises a stationary hinge part (12) in arranged or arrangeable at or in a chassis of the domestic appliance (20). The door hinge system (10) comprises a pivoting hinge part (14) connected or connectable to the door (30). The door hinge system (10) comprises a driving device (16, 18, 22, 24) for driving the pivoting hinge part (14). The driving device includes at least one motor (16) coupleable to and decoupleable from the pivoting hinge part (14). The driving device (16, 18, 22, 24) is automatically controllable. The pivoting hinge part (14) is manually pivotable, if the motor (16) is decoupled from the pivoting hinge part (14).

The present invention provides a cover structure, which includes a body, a first cover and a second cover. The body is provided with a first opening and a second opening. The first opening and the second opening are adjacent and are configured at an interval from each other so as to form a frame between the first opening and the second opening. The first cover includes a first cover plate and a first seat plate. The second cover includes a second cover plate and a second seat plate. The first and second seat plates are disposed in a protruding manner on side edges of the first and second cover plates, and are fixedly connected to the frame. The first and second cover plates cover the first and second openings, and are turnable relative to the first and second seat plates so as to open the first and second openings.

A door operating assembly (100) for operating a sliding door leaf (101) driven by a drive unit (112) along a sliding door rail (110), said door operating assembly (100) comprising a door bracket (150) configured to position the door leaf (101) relative the rail (110), a drive member (170) adapted to be driven by the drive unit (112), and a lever arm (160) having one end (161) pivotally connected to the drive member (170) and a remote portion (167) pivotally connected to the door bracket (150) via a cam structure (194) such that the vertical position of the door leaf (101) relative the rail (110) varies when the lever arm (170) pivots.

A joining structure of a door panel for a lavatory of an aircraft lavatory unit is provided. A plurality of pairs of end surfaces of a structural frame side hinge portion end surface and a door panel side hinge portion end surface facing each other in the vertical direction are alternately provided at intervals in the vertical direction. Bearing members each formed in a cylindrical shape and including a shaft insertion hole are disposed between at least two pairs of end surfaces adjacent to each other in the vertical direction, of the plurality of pairs of end surfaces. Both surfaces of the bearing member are in contact with each of the two pairs of end surfaces.
