Abstract: There is disclosed a door operation mechanism which can open/close a door to either right or left side. When a handle portion 116 is manually pivoted and displaced, it rotates cams 98 and 98a and, thus, a thrust-up rod 94 is pushed up and a push-down rod 94a is pushed down. The thrust-up rod 94 pushes and displaces a swing plate 66 in a hinge mechanism 16a. The push-down rod 94a pushes and displaces a swing place 66 in a hinge mechanism 16b. Then, the swing plates 66 in the hinge mechanisms 16a and 16b fail to bind hinge pins 22 and 26, respectively, and the right side of a door 14 is released. By pulling the right side of the door 14, the door 14 can be opened on the axis of hinge mechanisms 16c and 16d which are provided on the left side of the door. On the other hand, when a left unlocking mechanism 20b is operated, the door 14 can be opened on the axis of the hinge mechanisms 16a and 16b on the right side of the door. Therefore, the door 14 can be opened to either right or left side.

Abstract: A pre-hung door assembly kit enables the selective reversal of the hand of a pre-hung door mounted with hinges in a door frame for opening in one of right-hand and left-hand openings. The reversal is accomplished by rotating the door about a vertical axis and relocating vertical door jamb legs to maintain the correct juxtaposition of a previously prepared latching hardware location in the door with an appropriate previously prepared strike plate mortise in one of the door jamb legs so that factory precision is maintained with simplified field installation. Door stops are placed on the jamb legs so as to cover fasteners which secure the door frame in place in a building wall.

Abstract: A window opening mechanism is disclosed which moves the entire window sash outwardly from the window frame in a plane parallel to the plane of the frame. The mechanism for accomplishing this includes a pair of pivoted L-shaped lever arms on each side of the window. The short legs of these lever arms are substantially shorter than the long legs, and the ends of the short legs are pivotally attached to the window frame relatively close together. An operating mechanism is provided for moving the elbows of the lever arms toward and away from one another, and the ends of the long legs of the arms are pivotally connected at spaced apart points on the window sash. As the elbows of the levers on both sides are moved toward one another, the window sash is pulled toward the frame. When the elbows are moved away from one another, the pivoting action of the lever arms causes the window sash to be moved outwardly from the frame to provide a "stand-out" opening of the window.
