摘要： A tensioner for a fenestration unit operator includes a base and a guide including a track, the track slidably receiving the base such that the base is restricted to sliding in a first direction with respect to the guide along a sliding axis and a second direction with respect to the guide along the sliding axis that is opposite to the first direction. The tensioner includes a pawl and a ratchet each being a part of one of the sled and the guide, respectively, the pawl being in biased engagement with the ratchet to permit sliding in the first direction and restrict sliding in the second direction, the pawl being configured to be manually disengaged from the ratchet to permit sliding in the second direction. The tensioner includes a pulley coupled to the sled such that the pulley is free to rotate about a rotational axis that is transverse to the sliding axis.

摘要： Sliding operator assemblies and associated fenestration units, systems, and methods of use and assembly are described. Some such sliding operator assemblies transition a first, linear actuation force along a first axis (e.g., vertical) to a second actuation force along a second axis (e.g., horizontal) to cause a drive mechanism to impart opening and closing forces, respectively, on the sash. Some designs relate to belt-, twisted ribbon-, or band-drive sliding operator assemblies.

摘要： Disclosed herein is an electrostatic shutter system including an electrostatic shutter configured to be selectively raised and lowered based on a voltage applied to the electrostatic shutter, at least one sensor system configured to detect a position of the electrostatic shutter, and a controller communicatively coupled to the electrostatic shutter and the at least one sensor system. The controller is configured to apply an initial voltage to the electrostatic shutter to lower the electrostatic shutter, receive an output signal from the at least one sensor indicating the electrostatic shutter has reached a predetermined position, and based on the received output signal from the at least one sensor, apply an updated voltage to the electrostatic shutter to hold the shutter at the predetermined position.

摘要： A screen assembly used with a fenestration unit, the screen assembly capable of being installed at manufacture or retroactively to fenestration units. The screen assembly is installable on a fenestration unit having a frame and a window sash. The screen assembly includes a housing having a first housing member and a second housing member, wherein the housing forms a screen retention space between the first and second housing members when the screen assembly is in a closed position. It further includes a pleated screen positioned between the first and second housing members when the screen assembly is in the closed position, wherein the pleated screen includes a first end coupled to the first housing member and a second end coupled to the second housing member. The screen assembly also includes a catch element configured to releasably engage with the window sash.

摘要： Various systems and methods for demonstrating acoustic properties of a fenestration unit are provided herein. A system includes a sound demonstration apparatus having a sound insulating member defining an acoustic chamber, wherein the sound demonstration apparatus includes at least one open face. The system also includes a sound emitter operable to be positioned in the acoustic chamber of the sound demonstration apparatus, wherein the sound demonstration apparatus is operable to engage the fenestration unit at the open face of the sound demonstration apparatus. The method includes positioning the sound demonstration apparatus and a fenestration unit, such that the fenestration unit and the sound demonstration apparatus are operably engaged and form an acoustic chamber. The method includes activating a sound emitter.

摘要： A fenestration unit such as a door operable in a sliding mode and a bi-fold folding mode. Examples include a frame, a first panel, a second panel, and one or more fold hinges releasably pivotally connecting a second side portion of the first panel to a first side portion of the second panel and defining a folding axis. In the sliding mode (1) the fold hinges are configured to disconnect the first and second panels, (2) the first panel is in a closed position with respect to the frame, and (3) the second panel is configured to slide along a path generally parallel to the first panel between a closed position and a sliding open position. In the folding mode (1) the fold hinges are configured to pivotally connect the second side portion of the first panel and the first side portion of the second panel, and (2) the first panel and second panel fold with respect to one another about the folding axis with the first panel pivoting with respect to the frame and the second panel sliding and pivoting with respect to the frame as the first and second panels move between the closed positions and folding open positions.
