Abstract: Hinged window drive systems and window assemblies incorporating them provide for a combination of powered or motorized operation in addition to manual operation using a hand crank, with the opportunity for a user to switch between motorized operation and manual operation as needed.

Abstract: Power window operators, windows including the power window operators, and methods of using the same are described herein. The power window operators may offer the ability to control the timing and/or speed of the lock/unlock motion relative to the open/close motions of the operator arm of the power window operator and, if provided, a sash being driven by the power window operator.

Abstract: Fenestration lock assemblies, fenestration units including the lock assemblies, and methods of operating the lock assemblies. The lock assemblies offer a lock assembly construction that is capable of being assembled, installed, and used in a purely manual mode (i.e., in the absence of any driving unit such as, e.g., a motor, solenoid, etc.) or that may be assembled, installed, and used with a driving unit such that the lock assembly can be operated manually or in a driven mode, with the manual and driven modes of operation being unaffected by each other.

Abstract: Driven lock systems, fenestration units including the driven lock systems, and methods of operating the driven lock systems are described herein. The driven lock systems as described herein offer a combination of powered or motorized operation in addition to manual operation, with the opportunity for a user to manually switch the lock assembly between its locked and unlocked states as needed. The need for manual operation may arise if, for example, the system loses power, the controls of the system are unavailable, etc.

Abstract: The fenestration unit monitoring apparatus with tethers are configured to retrofit an existing fenestration unit to incorporate components that are capable of monitoring the locked or unlocked status of the existing lock assembly and/or the panel position status of a movable panel of the fenestration unit. The fenestration unit monitoring apparatus include a lock status sensor located on a tether such that the lock status sensor can be positioned within an existing fenestration unit lock assembly when a monitor housing of the fenestration unit monitoring apparatus is located on the fenestration unit adjacent the fenestration unit lock assembly.

Abstract: Embodiments include insulating glazing units with a photovoltaic cell structure disposed within and related methods. In some embodiments, the insulating glazing unit can include a first transparent pane and a second transparent pane. The insulating glazing unit can further include an internal space disposed between the first and second transparent panes and a spacer unit disposed between the first and second transparent panes. The spacer unit can be disposed adjacent to the perimeter of the first transparent pane and the second transparent pane. The spacer unit can have an inward surface facing the internal space. A photovoltaic cell structure can be disposed between the first and second transparent panes. The photovoltaic cell structure can be disposed over at least a portion of the inward surface of the spacer unit. The photovoltaic cell structure can include a photovoltaically active surface facing the internal space. Other embodiments are also included herein.

Abstract: A doorway with a sill attachment that increases a sill DP rating includes spaced vertical jambs, a head jamb, and a sill, all of which form a door frame, and a door panel mounted in the frame. The sill is a substantially hollow contain-and-drain type sill with a nosing provided with drainage openings. a substantially hollow sill attachment is mounted to and extends along the nosing and the attachment projects downwardly to a position below the openings in the nosing of the sill. The drainage openings communicate with the interior of the extension. Weep holes that communicate with the environment are located in the sill attachment at a position below the openings in the nosing of the sill. The sill and sill attachment may be formed as a single component, or as separate components assembled either in the factory or the field. The attachment increases a column height of water that can be accommodated by the sill before leakage occurs, and thus enhances the DP rating of the sill.

Abstract: A structure for joining structural members is disclosed. The structure joins an end of a first member to a side of a second member by a coupling insert. The coupling insert has a web coupling portion that is received by the end of the first member and a tenon portion that is received by a transverse opening in the side of the second member. The web coupling portion and the tenon portion are connected by a base plate.

Abstract: A doorway with anti-bubbling sill drain includes spaced vertical side jambs, a head jamb, and a substantially hollow contain-and-drain sill, all of which form a frame. The sill has an outside nosing provided with weep holes and weep doors and a threshold portion that directly underlies a closed door mounted in the frame. A drain insert is mounted within an oblong hole in the threshold portion of the sill for allowing water collected on the threshold portion to drain into the sill and for allowing air within the sill to vent. The drain insert has a top cover, from the end portions of which a pair of drains depend. The tops of the drains are spaced from the underside of the top cover to form drain entrances. An open vent space is formed between the two drains and terminates at its upper extent in drain holes formed through the top cover. When installed, the drains extend down into the interior of the sill with the drain entrances being flush with the floor of the threshold portion.
