A window includes an insulated glass unit and a frame supporting the insulated glass unit. The insulated glass unit includes a first glass pane and a second glass pane spaced from the first glass pane. A central plane extends through a pocket defined between the first glass pane and the second glass pane. The frame includes a first material visible on a first side of the window. The window also includes cladding connected to the frame. The cladding includes a second material visible on a second side of the window. The frame defines a cavity that extends between the first side and the second side and inhibits moisture from the first side contacting the second material. The window includes a thermal cavity defined by the frame and aligned with the pocket.

A temporary door latch device for a pre-hung door and casing. The door has a door lock cylinder opening and a door latch opening and the casing has a latch bolt opening. The device includes a female portion having a pair of opposed and spaced apart resilient fingers, each of said fingers having a plurality of inwardly extending teeth thereon. The female portion is receivable in the door lock cylinder opening and the door latch opening. The male portion has a pair of opposed and spaced apart fingers, each of the fingers having a plurality of teeth thereon. The male portion is receivable in the latch bolt opening and the door latch opening. The teeth on the female portion engage the teeth on the male portion in one orientation and are disengaged in another orientation.

An innovative ballistic door is disclosed that is destined for use in schools, offices and building structures. The innovative door comprises a hybrid ballistic core, comprising at least two sections, wherein one section is a heavy impact resistant material rated to NIJ level III strength to resist rounds fired from high-powered rifles, as well as resisting breaches from explosive devices such as pipe bombs and the like. AR500 steel plate having a thickness of inch meets this requirement. The remaining sections of the innovative ballistic hybrid core comprise at least one lighter-weight ballistic sheet material, such as E Glass fiber composite sheet, which at least comply with the NIJ level IIIA standard. This E Glass material is ideally suited to resist the impact of a pipe bomb explosion. The novel ballistic core construction allows a compromise between protective and practical weight requirements. In addition, the innovative ballistic door provides for substantial anti-breach protection of the latch and lock mechanism and hinges.

A profile (e.g. an extrusion profile such as a monoextrusion or co-extrusion profile), for a door and/or window part may include a metal layer of less than 1.0 mm thickness laminated at least partially to an outer side of the profile using an adhesive.

The present invention involves an entry door having a window glass situated in a door slab and a space between the window glass and the door slab. A plugless locking system is configured to fit in the space between the window glass and the door slab. The plugless locking system has a first plugless lock is configured to receive an external trim and is configured to mate with a second plugless lock. The second plugless lock is configured to receive an interior trim. The combination of the mated first and second plugless lock fit within the space between the window glass and door slab and secure interior and exterior trim to the entry door. Also disclosed is a method for using the plugless locking system in an entry door.

A lighting system attaches to a sectional door. The sectional door has a plurality of hinge-connected panels which roll along left and right tracks which are connected to a structure. Each panel has an inside surface. The sectional door is positionable to a closed position and to an open position. The lighting system includes a light which connects to the inside surface of a panel of the sectional door. A movable electric contactor connects to a panel of the sectional door, and a fixed electric contactor connects to the structure. A holder carries the fixed contactor, the holder is shaped and dimensioned to removably connect to either the left track or to the right track. In the open position of the sectional door the movable electric contactor is configured to contact the fixed electric contactor and energize the light.

The present invention relates to a structure of a non-interference front-surface opening/closing-type frame, and is advantageous in that, since a cover frame can be conveniently coupled right beneath a fixing frame, assembly of the cover frame and the fixing frame is substantially facilitated, it becomes easier to prevent the cover frame from being separated from the fixing frame by an external impact, and the vertical width between the lower portion of a rotating shaft of the cover frame and the lower portion of a compression piece is substantially reduced, thereby realizing slimness. The present invention is also advantageous in that: the cover frame can efficiently open/close the fixing frame without interference of the fixing frame; escapement of the rotating shaft from the shaft groove can be prevented while the cover frame opens/closes the fixing frame; there is no concern that an elastic member may act as an interfering element during assembly of the fixing frame and the cover frame; and it becomes easier to maintain the state in which the cover frame closes the fixing frame. The present invention is also advantageous in that, when the cover frame opens the fixing frame, the cover frame can open the fixing frame more easily with no concern that the cover frame may contact a structure, such as a building wall body, and be interfered with, thereby substantially facilitating extended application to metal furniture of industrial materials, such as picture frames and door frames, or construction window/door frames.

The structures described herein use an actuating system that can selectively switch between a lower and a raise mode of operation by rotating a rod assembly in two different directions, and use a downward displacement of a pull member to lower and raise the window shade depending on its switching state. The actuating systems are simple to operate, allow convenient adjustment of the window shade, and are safe as the pull member has a limited length of extension.

A cover is fitted to an aperture in an enclosure. A biasing mechanism is connected to the cover to mechanically bias the cover in an open position. An adhesive member is disposed around the aperture to retain the cover in a closed position against the bias of the biasing mechanism. A release mechanism effects release of the cover from the adhesive member by diminishing adhesion thereof in response to an open command signal.
