A dampened hinge construction for braking pivoting movement of one structure relative to another. The dampened hinge construction can be utilized in a folding table assembly in an aircraft passenger suite including a base panel and at least one folding panel pivotally attached to the base panel by multiple dampened hinges. Each dampened hinge includes a first assembly attachable to a first structure and a second assembly attachable to a second structure such that the first structure is pivotable relative to the second structure between a first condition and a second condition, such as a folded condition and a planar condition, and at least one damper that brakes pivoting movement of the first structure relative to the second structure as the first condition or second condition is approached.

An access control apparatus having a protective covering configure to cover at least one of a subject or an object inside said protective covering is provided, where an opening is configured to provide access to the at least one of a subject or an object and a covering element configured to selectively cover said opening. A receiving element is provided on the protective covering and an activating device with an activating element is provided external to the protective covering. A motor is coupled to the covering element, wherein said motor selectively moves the covering element to at least partially unblock the opening based on a wireless activation signal and a distance between the activating element and the receiving element being within a predefined distance and to completely block the opening based on the wireless activation signal and the distance between the activating element and the receiving element being greater than the predefined distance, effectively limiting the exchange of contaminated or adverse environments between an internal area of the protective covering and an area outside the protective covering. The covering element can be an integral covering or an iris diaphragm arrangement.

A dial ring assembly for an electromechanical combination lock includes a housing configured to be mounted on an exterior of a securable enclosure, a dial rotatably disposed on the housing, the dial being rotatable about a dial axis for use in connection with entry of a combination, a lever rotatably disposed on the housing, the lever being rotatable about a lever axis, an external generator disposed in the housing, the external generator being configured to generate electrical energy through rotation of an external generator shaft of the external generator, and a gear train disposed in the housing and operatively connecting the dial, the lever, and the external generator shaft such that rotation of the dial rotates the external generator shaft to produce electrical energy and rotation of the lever rotates the external generator shaft to produce electrical energy.

Apparatus allowing ventilation through a ventilation shaft to an underground ventilation duct fluidly communicating through the ventilation shaft to an atmospheric opening of the shaft and on threat of flooding operable to prevent downward flow of surface water into the underground ventilation duct includes one or more hinged panels closing a ventilation passage between the top and bottom of a support fitting in the shaft to prevent flooding. The panels have handles on their topside and pivotable arms on their underside and are liftable to an upright home position allowing ventilation, using tools to reach through grating covering openings on the shaft and lift the panel handles and after the panels are partially lifted, using reach tools to engage and lift the arms to press them again support sidewalls to exert lateral force on underside of the panels to complete upward rotation to the home position.

An injection molded housing includes a first piece, a second piece, and a wall defined by the first piece removably joined to the second piece by a joint at abutting surfaces of the first piece and the second piece. A central catch is integrally molded with the first piece, protruding from the wall. A latch is integrally molded with the second piece, and connected to the second piece first and second living hinges. A half-knuckle is integrally molded with the second piece, protruding from the wall. A hinge pin is fixedly attached to the latch. The latch is bendable at the living hinges to align the hinge pin with the half-knuckle. The latch is rotatable about the hinge pin to engage the central catch and selectably prevent the first piece from being disengaged from the second piece.

A door hinge assembly includes: a door frame defining a frame opening and a jamb at one side of the frame opening, the jamb including two frame corners protruding into the frame opening and a jamb brace connecting the two frame corners across the frame opening, the jamb brace defining two spaced-apart hinge holes therethrough; a door movable to selectively provide access through the frame opening, and an elastic cord connecting the door to the door frame, the cord extending sequentially through a first of the two hinge passages, through a first of two passage openings at the jamb edge, through a first of the two hinge holes, across the jamb brace, through a second of the two hinge holes, through a second of the two passage openings at the jamb edge, and through the second of the two hinge passages.

A junction box assembly including a box and a selectively displaceable lid, the lid including one or more articulating lock sockets and one or more lock hinge sockets. Hinge arms can be pivotally coupled to the box, with a first hinge arm also being pivotally secured to an articulating hinge socket to accommodate pivotal displacement of the lid from the box, as well as pivotal displacement of the lid about a portion of the first hinge arm. A second hinge arm can be selectively removable from secure engagement with the lock hinge assembly. Further, a tamper resistant pin can extend through the upper head portion of the second hinge arm when the second hinge arm is engaged with the lock hinge socket so as to lock the second hinge arm to the lid, and thereby secure the lid at a closed position on the box.

The invention relates to a public sanitary device (1), comprising a housing with walk-in positions (20, 30), each with a receptacle (21, 31) for human excrement and/or urine. The housing is provided with a first housing part (11) intended for placing underground, a second housing part (12) received movably in the first housing part and a third housing part (13) received movably in the second housing part. The sanitary device comprises a drive for moving the second and third housing parts between an underground rest position and an above-ground position of use. At least one of the walk-in positions is provided with a door for closing the walk-in position. The door comprises at least a first and a second door segment (41, 42), which door segments are movable in longitudinal direction relative to each other. The second housing part (12) comprises the first door segment (41) and the third housing part (13) comprises the second door segment (42).

Hinge members and foldable structures incorporating the same are described herein. A foldable structure includes a section, a brace, and a hinge member attaching to the section to enable the section to move between a folded position and an extended position. The hinge member includes a first bracket and a second bracket that are hingedly joined to each other. The first bracket includes a first flange that is integrally formed and extending from the first bracket. The first brace is attached, between the first flange of the first bracket and a surface of a different structure, to the first hinge member.
