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 wind turbine tower includes a door access opening in a down tower area of the tower. A hinged door panel covers the door access opening, with a ventilation opening defined through the door panel. A multi-sided intake structure, such as a box-like structure, is connected to an exterior of the door panel over the first ventilation opening. The intake structure extends transversely from the door panel and includes a top side, a bottom side, and at least two vertical sides extending between the top side and the bottom side. The vertical sides are open to air flow therethrough. The top and bottom sides may also be open to air flow therethrough. Air from multiple directions is drawn into an interior of the wind turbine tower through the intake structure and ventilation opening. A filtering system with first and second stage filters may be incorporated with any of the intake structures.

A diagonal draw bar having a micro ventilation function includes a first lever, a second lever, a retaining lever, a spring, a latching member, and an actuating lever. The first lever defines a first rivet hole, a second rivet hole, and provides a positioning hook. The second lever defines a third rivet hole and connects with the first lever. The retaining lever defines a fourth rivet hole and connects with the retaining lever, the retaining lever defines a through hole. The spring is latched within the through hole. The latching member extends through the spring. The actuating lever is provided with a projection for pushing the latching member upward.

A natural ventilation apparatus 1 includes a window frame 2 which is installed in a building; a framed panel 4 disposed in an opening portion 3 defined by the window frame 2; and opening/closing means 5 for opening and closing the opening portion 3 on the basis of an air current. The opening portion 3 is adapted to be opened by the opening portion opening movement of the framed panel 4 moving toward a building exterior 7 side, and to be closed by the opening portion closing movement of the framed panel 4 moving toward a building interior 8 side.

An integrally molded plastic part has a main body with an opening, and a door connected to the main body via an integral hinge and snapping into a closed position closing the opening. The door, at each of its two sides extending away from the hinge, includes a stopping surface via which the door, in its closed position, abuts against a supporting surface of the main body, and a snap-in hook protruding from the stopping surface and comprising a retaining surface which engages behind an edge of a flange confining the supporting surface. A distance between the two retaining surfaces as compared to a distance between the flanges confining the two supporting surfaces decreases with increasing distance to the hinge, whereas distances between the retaining and stopping surfaces as compared to distances between the edges of the flanges and the supporting surfaces increase with increasing distance to the hinge.
