A device may limit opening of a sash hingedly coupled to a master frame, and includes: a bracket attached to the sash; a first arm having a first end pivotally coupled to the bracket; a second arm having a first end pivotally coupled to the first arm's second end; means for biasing the second arm into a retracted position; and a release assembly. The release assembly is secured to the master frame and includes a hook pivotable between a first position and a second position, which, in the first position, may be releasably received in an opening in the second end of the second arm when the second arm is in the retracted position, as the sash is closed and received within the master window frame The second arm is disengaged from the hook, permitting full opening of the sash, when the hook is pivoted into the second position.

A door stop includes a scissor link member including a pair of links pivotably coupled together at a central pivot point. The scissor link member has a first end pivotally coupled to a door and a second end pivotally coupled to a floor. The pair of links are configured to abut against one another adjacent the central pivot point when the door is fully open to prevent pivoting at the central pivot point for holding the door open. The scissor link member is releasable such that the pair of links pivot about the central pivot point when the scissor link member is released, thereby enabling closing of the door. The pair of links fold into a nested arrangement when the door is fully closed. The pair of links are configured to deform under dynamic loads to protect the surrounding aircraft structure and indicate a need for inspection.

An arrangement includes a folding door or folding-sliding door, which comprises at least two door leaves connected to one another in an articulated manner. An ejector device is arranged on a first of the two door leaves for at least partially transferring the folding door or folding-sliding door from a folded open position into a closed position. The at least two door leaves are arranged in a common closing plane, and a holding element is arranged on the second of the two door leaves. The ejector device has an ejector element which can be brought into engagement with the holding element in the open position to hold the folding door or folding-sliding door in the open position. The ejector element is configured to apply a force to the holding element to move the second door leaf from the open position into the closed position.

A locking assembly is operatively coupled to a first door and a second door of a pass-through housing. The locking assembly includes a first locking pin on the first door and a second locking pin on the second door. The locking assembly engages the first locking pin and locks the first door when the second door is opened, and engages the second locking pin and locks the second door when the first door is opened.

Disclosed herein is a fenestration assembly. The assembly includes a movable sash assembly, a first lock counterpart connected to the movable sash assembly, a fixed sash assembly, a second lock counterpart connected to the fixed sash assembly, and a sill configuration. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a first height, the movable sash assembly is lockable to the fixed sash assembly. While the fixed sash assembly is mounted to the sill configuration, and while the movable sash assembly is mounted to the sill configuration at a second height, the movable sash assembly is lockable to the fixed sash assembly. While there is an absence of locking between the movable and fixed sash assemblies, the movable sash assembly is movable relative to the sill configuration.
