Abstract: A metal door or window frame comprises mobile and fixed frameworks each formed by a sub-frame including a substantially tubular section effective to be positioned on the side thereof facing the room interior and a cover section effective to be positioned on the side thereof facing outwards, between the sub-frames and the cover sections insulating material elements being provided for defining an uninterrupted heat insulating barrier therebetween.
Abstract: A ceiling-mounted attic door features a continuous outer panel of flame-resistant plaster board, an intermediate layer of thermal insulating material and marginal sealing gaskets and insulating strips arranged to thermally seal the marginal edges of the door when it occupies a normally closed position within its associated door opening.
Abstract: The invention relates to a decorative stained glass insert unit which is attachable to an existing window unit to create an esthetically pleasing window treatment effect.
Abstract: A sealing means for doors of a railroad hopper car and an apparatus and method for forming a sealing strip. The sealing means comprises a preformed strip of RTV silicone rubber fixed to the door at its edges and receiving a flange on the door frame. Preferably the strip is formed by extruding RTV silicone rubber from a traversing head onto a screen.
Abstract: A protective enclosure for building openings such as windows and doorways wherein the protective enclosure comprises a peripheral frame member that circumscribes the openings and pivotally mounts a transparent shielding unit. The unit which may function as a window or door, depending upon the application, is provided with a unique hinge and locking arrangement which facilitates the easy opening and closing of the unit with respect to the opening; yet one which provides security against the unauthorized entry through the opening in that the unit may not be removed from the building opening from the outside of the building when the unit is in a closed position.
Abstract: A cab intended for use as the operator's cab of a tree harvester vehicle has an access door in the leading surface of the cab. The cab door frame, and the access door, are defined by square tubes which are turned 45.degree. with respect to the plane of the door opening to define oblique interfaces between the door edge faces and the door opening faces.
Abstract: A ventilator hatch assembly for vehicles, watercraft and the like, which is characterized by having a hatch member, which is interconnected to a mounting frame restable within a ventilation hatch opening for pivotal movements between alternative open ventilating and closed, latched, non-ventilating positions. The hatch cover and mounting frame are interconnected by separable hinge means and separable flip-action or snap-action latch means which operably cooperate to accommodate rapid opening and closing movements of the hatch cover and also to facilitate complete and rapid removal of the hatch cover from the hatch opening to permit the latter to serve as an emergency exit from the vehicle or craft.
Abstract: A hinge construction particularly designed for exterior usage is provided by the present invention. Two planar sections are comprised of complementary land portions and cutaway portions disposed in spaced apart relationship along the length of the hinge. The cutaway portions of one section receive the land portions of the other section. With such configuration only a single thickness of metal separates the hinged member from the mounting member. First and second barrel mounting sections extend in the same direction outwardly away from the respective first and second planar sections. The two barrel mounting sections in turn mount complementary hinge barrels which, when positioned in alignment, receive a hinge pin. As a result of the hinge mounting sections projecting outwardly away from the hinged member and the mounting members, a weather shield is formed to help keep moisture and dirt out of the opening that is closed by the door.
