A hinge assembly includes a first and a second set of friction elements engaged each other by an applied force perpendicular to the friction elements. The first and the second set of friction elements are capable of rotational movement about a cylindrical element that passes through each of the friction elements. Also, the first set of friction elements is capable of movement relative to the second set of friction elements. However, the first set friction elements can remain in a fixed position based upon the applied force, until an external force overcomes the applied. During rotation of the first set of friction elements about the cylindrical element, the frictional engagement that controls the position of the first set of friction elements is based primarily on engagement between the friction elements, as opposed to engagement, if any, between the friction elements and the cylindrical element.

A joining structure for two door members forming a door member for entrance opening and closing of an aircraft lavatory unit is configured so that a pair of brackets provided on the pair of door members are joined swingably by a bracket joining shaft; and one ends of a pair of covers are joined to the pair of brackets by bracket cover joining shafts, and the other ends of the pair of covers are joined swingably by a cover joining shaft, at a section farther away from the lavatory than the bracket joining shaft.

A hinge assembly includes a first hinge element having a hinge pin with upper and lower portions and an engagement portion outwardly extending from the hinge pin. The engagement portion of the first hinge element includes a lower surface having an upwardly angled portion and an abutment surface. A second hinge element includes a body portion surrounding a hollow interior portion and further includes a contoured upper rim having a downwardly angled portion and an abutment surface. The lower portion of the hinge pin of the first hinge element is slideably received in the hollow interior portion of the second hinge element. The first hinge element rotates between a first position, wherein the abutment surface of the first hinge element abuts the abutment surface of the second hinge element, and a second position, wherein the abutment surfaces of the first and second hinge elements are spaced-apart from one another.

An appliance includes a hinge assembly for coupling a door to a housing or body of the appliance. The hinge assembly can include a body-mounted component, such as a body-mounted hinge or a body-mounted receiver. The body-mounted component is secured to a vertical support of the appliance. A mating component of the body-mounted hinge or body-mounted receiver is attached to the door.

A joining structure for two door members forming a door member for entrance opening and closing of an aircraft lavatory unit is configured so that a pair of brackets provided on the pair of door members are joined swingably by a bracket joining shaft; and one ends of a pair of covers are joined to the pair of brackets by bracket cover joining shafts, and the other ends of the pair of covers are joined swingably by a cover joining shaft, at a section farther away from the lavatory than the bracket joining shaft.

A radial progression hinge cap has a cap body that is configured to attach to a door jamb of a door frame above a geared continuous hinge that supports a door in the door frame. The cap body has a rear attachment channel that is configured to be attached at the door jamb. The cap body also has an upper surface that slopes downward from a top edge of the rear attachment channel to a front distal edge of the cap body. The front distal edge protrudes a threshold distance away from the rear attachment channel so that the upper surface of the cap body spans over and conceals a top surface of the geared continuous hinge and an upper corner of the edge portion of the door as it moves between the open and closed positions.

A frame assembly supporting an overhead door has a horizontal header connected to upright columns or posts with splice assemblies. Fasteners mounted on the columns cooperate with retainers on the splice assemblies to position and connect the columns to the header. Hinge assemblies pivotally mount the door on the header for movement between open and closed positions.

A frame assembly supporting an overhead door has a horizontal header connected to upright columns or posts with splice assemblies. Fasteners mounted on the columns cooperate with retainers on the splice assemblies to position and connect the columns to the header. Hinges pivotally mount the door on the header for movement between open and closed positions. Linear actuators connected to the frame assembly and door are operable to move the door between door open and door closed positions.

A door mounting system comprises a hinge assembly (101) and a door frame (5), the length of the hinge assembly (101) corresponding to a height of the door frame (5). The hinge assembly (101) comprises a first hinge member (2) coupled to the door frame (5), an intermediate hinge member (3), and a second hinge member (4) for attachment to a door leaf (1). The first hinge member (2) and the intermediate hinge member (3) are rotatably coupled to each other around a first hinge axis, and the second hinge member (4) and the intermediate hinge member (3) are rotatably coupled to each other around a second hinge axis. A locking element is adapted to selectively inhibit rotation of the intermediate hinge member (3) relative to either the first hinge member (2) or the second hinge member (4).

A foldable electronic device including a first body, a second body, a flexible display disposed on the first and the second bodies, a hinge assembly connected between the first and the second bodies, an extension chain assembly, and a linkage is provided. The first and the second bodies are rotated relatively to be unfolded or folded via the hinge assembly. An end of the linkage and an end of the extension chain assembly are pivoted together and coupled to the first body in a sliding and pivoting manner. Another end of the linkage is pivoted to the hinge assembly, and another end of the extension chain assembly is pivoted to the second body. In a transforming process between the folded and the unfolded states, an extension traveling of the extension chain assembly compensates a size difference of the flexible display between the folded and the unfolded states.
