An aircraft seat module having a flight passenger seating area has a door unit which in at least one operating state is configured at least to close a passage region to the flight passenger seating area, and has a locking device for the door unit, which is configured to lock the door unit in an open position, in particular a maximally open stowage position, and to this end comprises at least one actuator device which has at least two movably supported locking elements, which are in each case adjustable between a locking position and an unlocking position, wherein that the locking device has a locking state indication unit which at least in the maximally open position of the door unit is configured to detect and indicate incomplete locking of at least one of the two locking elements.

A door assembly may include a first sidelite configured to be operably coupled to a first door jamb, a second sidelite configured to be operably coupled to a second door jamb where the first and second sidelites are disposed in a common plane and define a door opening between the first and second sidelites, a first sliding panel, a second sliding panel where the first and second sliding panels are movable from a closed position disposing the first and second sliding panels to block access through the door opening and an open position in which the first sliding panel is proximate the first sidelite and the second sliding panel is proximate the second sidelite, a first partial door panel, and a second partial door panel. The first and second sliding panels are disposed in a second plane parallel to the common plane in both the open and closed position. The first and second partial door panels are operably coupled to the first and second sidelites, respectively, via hinge assemblies. The first and second partial door panels have a closed state in which the first and second partial door panels are each disposed in the common plane blocking access through the door opening, and an open state in which the first and second partial door panels are each disposed out of the common plane.

Apparatuses, methods, and systems for providing a locking apparatus for resisting movement of an openable element are described. The locking apparatus includes a body, an actuator, a lifting member, at least a portion of the lifting member being configured to be raised or lowered relative to the body according to an output of the actuator, the lifting member comprising a contact surface configured to restrict movement of the openable element, and a strap coupled to the body and to the lifting member, the strap configured to permit the lifting member to flex based at least in part upon contact between the lifting member and the openable element and to transfer energy received at the lifting member into the body of the locking apparatus into a surface to which the locking apparatus is mounted.

A hot melt safety door holder device includes: a first fixing part on one side of swing end of swing door sheet; a holder with a transverse through hole and the outer hole end faces towards the first fixing part; a second fixing part in the transverse through hole, the first radial end faces towards the outer hole end of transverse through hole, the second radial end faces towards the inner hole end; a conically cylindrical space, formed between the periphery of the second fixing part and the transverse through hole, and the inside and outside diameters of the end between the transverse through hole and the second fixing part corresponding to the space tapering end of conically cylindrical space are fitted with each other. The shape of the low-melting metal material filled in the conically cylindrical space matches the shape of conically cylindrical space, resulting in equal wall thickness.

An item may be provided with a body that forms an enclosure. The body (12) may have body portions (16, 18) that open and close along a seam (14). An elongated magnetic fastener (36) may run along the seam. The magnetic fastener may have first (38) and second (40) portions on opposing sides of the seam. The first and second portions may include magnets. When the magnetic fastener is operated in a closed state, the magnets in the first and second portions attract each other and pull the first and second portions of the fastener together to close the seam. When the magnetic fastener is operated in an open state, the magnets in the first and second portions repel each other and push the first and second portions of the fastener apart to open the seam.

Disclosed is a door holder which comprises a planar, rectangular plate the plate constructed with two integral channels, oriented parallel to the left and right edges, respectively, of the rectangular plate. The door holder serves as a means to prop open a heavyweight, commercial door, the subject door being operated by spring-loaded hinges. The door may be continuously held open by means of bracing either edge of the rectangular plate against the outer edge of a doorstop. In conjunction with the placement of an edge of the door holder against the doorstop, one of the integral channels is then mounted so as to straddle the top of the shoulder of the leaf of one spring-loaded hinge. In this manner, the door is forcibly held in an open position, forming a ninety-degree angle between the plane of the door frame and the face of the door.
