A rotary latch assembly includes a latch release having a detent and a pawl that is rotatable relative to the latch release about a pivot axis. The pawl includes at least one catch for engaging the detent to releasably hold the pawl in a fixed orientation. At least two contact surfaces are offset from the pivot axis. At least one spring is mounted to the pawl. The pawl is rotatable relative to the latch release between a neutral orientation and at least one non-neutral orientation. The at least one spring accumulates a stored energy during rotation of the pawl toward the at least one non-neutral orientation in response to force applied to one of the at least two contact surfaces, and the spring releases the stored energy when force is removed from one of the at least two contact surfaces to rotate the pawl toward the neutral orientation.

A door holding device and system is disclosed that holds a door in a partially open configuration. The door holding device includes a first arm assembly that attaches to a door, a second arm assembly that attaches to a door frame, a movable clamping mechanism that clamps the second arm assembly to the door frame, and a pivot device that allows the first arm assembly and the second arm assembly to pivot with respect to each other.

A latch assembly is provided that includes a latch arm having a rotational axis and an engagement surface on a distal end of the latch arm a length from the rotational axis. The engagement surface is stowed in a stowed state of the latch arm. The latch arm is configured to receive a pushing force to depress the latch arm a predetermined distance along the rotational axis. The latch assembly also includes a turret assembly having a top end with the latch arm mounted thereon. The turret assembly is configured to, in response to the pushing force being applied to the latch arm, raise and rotate the latch arm about the rotational axis to thereby transition the latch arm from the stowed state to a deployed state in which the engagement surface is exposed.

A stay is provided. A first part (12) including a base (16) for attachment to a wing or to the frame surrounding the wing and an elongate internally threaded tube (24) which is attached to the base (16) in such manner as to be free to pivot with respect to the base. The stay further includes a second part (14) including a rod (58) with threading compatible with that of the tube (24). A locking element (50) with a circumferential groove is attached to and protrudes transversely from the rod (58) and there is a cylindrical element (40) forming part of a base (34) for attachment to the wing or frame. There is first bore in the element (40) for receiving the element (50) and a threaded second bore intersecting the first bore for receiving a cap screw which enters the groove to prevent withdrawal of the element (50) from the first bore. The second bore is closed by a disc (62) with an Allen key hole opening (64) in it through which the capscrew can be turned.

A fenestration system is disclosed. In some examples, the fenestration system includes one or more movable window sashes and a toggle assembly. In some examples, the toggle assembly operates to limit the degree to which the window sashes are opened or otherwise moved relative to one another. In some examples, a window sash may be opened a designated amount before the toggle assembly operates to obstruct it from being further opened.
