A motorized window with one or more motors and a frame with a slidable segment is disclosed. A drive system with gears, transmission or worm drive engage with a gear track mounted to the frame or slidable segment. Rotating a first gear in a first rotational direction causes the first gear to pull the slidable segment in a first linear direction. Rotating the first gear in a second rotational direction causes the first gear to pull the slidable segment in a second linear direction. Preferably, a controller controls the operation of the motors. Sensors inform the controller, and user input via a mobile device enables both direct user control and programming of the controller.

A fenestration unit including a first panel having a leading portion and a trailing portion, a second panel, and a frame including a first lateral member and a second lateral member. The first lateral member has a trolley space configured to slideably receive a trolley assembly. The trolley assembly includes a first trolley coupled to the leading portion of the first panel and a second trolley coupled to the trailing portion of the first panel. Each of the first and the second trolleys includes a guide pin slideably received in the leading and trailing tracks, respectively. The guide pins are configured to guide the first panel out of a coplanar relationship with the second panel when the first panel is slid to an opened position and guide the first panel into a coplanar relationship with the second panel when the first panel is slid to a closed position.

A building system may include an external structural frame which includes a plurality of columns and beam, a diaphragm which includes a plurality of floor panels, each of the plurality of floor panels having a longitudinal direction and a transverse direction. The plurality of floor panels are supported by a plurality of diaphragm beams arranged along the transverse direction, and a coupling between each of the transverse beams and the external structural frame, wherein loads are transmitted from the diaphragm to the external structural frame only via the couplings between the transverse beams and the external structural frame.

A sealing unit for a sliding door has a lowering seal and a catch element (6). A mechanism (7, 4, 8) is designed to convert a sliding movement of a first sliding door element (T) relative to a second sliding door element (B) into a movement of a sealing strip arrangement (2, 3) that occurs substantially transversely to the sliding movement. The mechanism (7, 4, 8) has a rotatable or pivotable pick-up element (70) for picking up the sliding movement. In order to lower the seal, the pick-up element (70) lies on the catch element (6) in the lowering direction such that the weight force of the door thus assists the lowering operation.

The panel of the panel system is movable and is intended to be positioned and connected between an essentially parallel lower guide and upper guide of the system in order to move the panel on the lower guide. The panel, for example, its lath, includes at least one claw configured to grip the lower guide, which is connected to the panel so the claw is able to move in the vertical direction when the panel is vertical. When pulled away from the panel, the claw may be attached to the lower guide. The claw tends to retract by itself towards the panel, away from the lower guide, which may include a rail to which the claw is attached and on which the panel may rest as it moves along the lower guide. As an extension of the rail may be an auxiliary rail, including, for example, a guide surface.

A window frame assembly has a built-in foldable screen, having a body, the body having at least a first frame part and a second frame part; the first frame part has at least a first end surface and a second end surface; the second end surface is fixedly connected to the second frame part; the first end surface is provided with a protruded guiding convex part; the guiding convex part is provided with a line receiving groove; and two sides of the line receiving groove are respectively provided with a concave part. The above structure has the benefits of enabling the guiding convex part located on the transverse frame in the foldable screen module to be re-assembled on the structure of the window frame assembly, thus reducing the number of foldable screen module components, and also improving the convenience of assembling the foldable screen module in the window.

A hideable bay window is provided. The hideable bay window comprises a window frame, a first horizontal turning plate, a second horizontal turning plate, a vertical translation plate, a first vertical sliding assembly, and a second vertical sliding assembly. The hidable bay window further comprises a pair of bottom support mechanisms. Compared to traditional windows, the present window can be transformed between a fixed window status and a bay window status smoothly and allows the space for the windows to be set according to the needs of the user.

A recessed window assembly comprises a housing configured for recessed installation within a frame wall of a building adjacent a window opening and at least two sliding window components slidingly disposed within the housing such that the sliding window components are at least substantially disposed within the housing when in a non-deployed position and that fill the window opening when in a deployed position. The window components can comprise, for example, a transparent untinted window, a transparent tinted window, a translucent window, a window screen, a security plate, an electric fan, or an air filter.

A fenestration unit includes a fenestration frame with a first frame member, and a sash including a sash frame to support a glazing unit. The fenestration unit includes a channel defined in one of the first frame member and the sash frame that extends along a first axis. The fenestration unit includes a retainer base associated with the other of the first frame member and the sash frame that extends along the first axis. The fenestration unit includes a retainer removably coupled to the first frame member and the sash frame to removably retain the sash frame on the fenestration frame. The retainer has a first retainer arm, a second retainer arm and a third retainer arm. The third retainer arm is movably coupled to the channel and the first retainer arm is movably coupled to the retainer base.
