A number of panels are secured to the beams and rotated in concert with the beams. A rod is vertically disposed in the frame and includes a number of worm gears for engaging with the pinions such that the beams and the panels may be rotated by the rod when the rod is rotated. The rod may also be rotated by a motor. The window includes a configuration safety enough for protecting against burglars and for use as a sunshade.

Abstract: A security window guard is permanently installed into pre-existing awning-type windows (also referred to as Miami windows) by first fastening a separate strip inside the window jambs with fasteners that anchor the strip through a jamb to the wall. This strip has an array of holes that incorporate lead-in guides extending from each hole to a free edge of the strip. Subsequently, holes are drilled in the window jambs at locations aligned with a plurality of pins that protrude from the security frame, an array of fixed pins formed on one side of the security frame is inserted into one set of holes, and the security frame is pushed into the window frame. When the security frame is pushed into the window frame the lead-in guides act to compress spring-loaded pins extending from an opposing edge of the security frame.

Abstract: Louvre structures wherein holding members for the louvres are carried on bars which extend across a frame and are pivotally mounted with respect to the frame so as to be axially rotatable relative to the frame and which cannot be removed from the frame, at least when the window is installed.

Abstract: An removable frame assembly for building apertures that can be readily pushed out by a user in an emergency situations. It includes a fixed frame rigidly mounted to the aperture and a second frame removably mounted to the fixed frame. The removable frame rigidly houses the window for the aperture and, optionally, security bars to prevent trespassers from entering through the window. The security bars can be installed inside or outside the building. A relatively remotely located locking mechanism releasably keeps the fixed and removable frames together. A spring member sandwiched between the fixed and removable frame members urge the separation of the two when the locking mechanism releases them.

Abstract: A window assembly controls ventilation and prevents passage through the window opening. Provides hardened steel horizontal bars spaced apart vertically a distance that prevents passage. The bars are welded to hardened steel frame members. The steel assembly is anchored in the wall by resistant anchoring elements. The bars may be secured in place by other means. Glazed aluminum vents have top rails that enclose the bars and pivot upon them. Aluminum frame members enclose the steel frame members and support operator means that rotate the vents on the bars to open and close the vents. The angle of opening may be limited to prevent the vent extending beyond the wall at walkways.

Abstract: An improved security bar system for louvered windows is disclosed. The window unit has louvered blades which pivot on horizontal stub shafts.The security bars are mounted on the stub shafts where the louver blades hide them from view and provide an esthetically pleasing window unit. Each security bar has a hardened steel rod with holes bored in each end for receiving the stub shafts and a hardened steel sleeve which freely rotates on the steel rod and covers the rod and stub shafts. The steel rod freely rotates on the stub shafts which are themselves freely rotatable. Therefore, any attempts to cut the security bar will cause the steel sleeve to rotate. Should the steel sleeve be held stationary and cut, the covered steel rod will rotate due to the action of the saw blade.

Abstract: In a shutter assembly, individual shutter blades are connected to ribs of an auxiliary frame by way of living-type hinges, so that the living-type hinges form the pivot axes of the shutter blades. Furthermore, an actuating rod is provided, which is also connected by way of living-type hinges to the shutter blades. The auxiliary frame with the shutter blades and the actuating rod are thus combined into one structural unit which can be manufactured in one single operation in a three-part mold. This arrangement enables the shutter assembly to be manufactured at low cost by the injection molding technique so that assembly operations become unnecessary.
