Abstract: The DOOR WINDOW, FIG. 1 may be one solid square or round frame or may also consist of two main frames 2 & 3, to fit a square or round door hole one inch to twelve inches in length (vertical dimension or height) and about two and one half inches to twelve inches in width (horizontal dimension), or from two inches to ten inches in total diameter, depending on what size the door frame or door frame supports would allow.   Note that for the purpose of making it known considering it may not be required for the the purpose of this patent that it is the intention of the author or the applicant of this patent application to have a sliding door in front of the main door for privacy purposes and better heat insulation as illustrated in FIG. 6. This sliding door which can be made of hard plastic, dark in color or solid metal or sheet of wood 14 is opague and slides to the side that the main door opens to. In the case of a round door-window, the sliding door is replaced by a round door that pivots at one point to open and close it. Again, it pivots on the side where the main door opens to. The sliding door (or round door) slides and is held by tracks 13 that is screwed into or bolted (added) to the assembly FIG.1.   The two frames 2 & 3 are slid into the hole to make a perfect fit. One frame, 3 holds the glass or thick, hard, transparent plastic door 4 which can be fastened to that frame in two different manners which is explained below. The other frame has the slot where the lock lever fits into. This frame (2) also has a narrow protrusion, 7 in FIG. 5, welded or molded to it from top to bottom of its vertical length which serves as a door stop and also for security purposes. The other frame may also have the narrow vertical protrusion, also for security purposes.   The glass or plastic door 4 can be fastened or secured to the door window frame in two ways: First, by the use of bar support-lock and secondly, by hinges. The one best way to secure the door to the frame is by using a horizontal bar support-lock 12, FIG. 4, bolted or screwed to the plastic or glass door. This is illustrated in FIGURE 4. This bar support-lock doesn't require the use of lock, 11 or hinges, FIG.5. It pivots on one side of the frame and is lock on the other side, by a pin 10, FIG. 4. An outside plate is used to fasten the door to the bar support lock. The outside plate can be fastened to the door by welding to it the bolts or studs for the bar. The outside plate can also be fastened to the door by rivets, that is, rivetting the outside plate and horizontal bar support lock, sandwiching the door between them.   The second option in securing the door to the frame is by using regular hinges. When hinges (regular door hinges) are used, the opposite or outside part of the door is covered with a metal plate, covering the hinges and its screws or studs for better security. The outside plates can be fastened to the door by welding to it the bolts or studs for the hinges. It can also be fastened to the door by rivets.     The plastic or glass door is locked into the close position by a regular door, or cabinet, or glass rotating lock 11, FIG. 5 that can be with a key or without. The lock lever goes inside an opening or slot 1, FIG. 1 the exact size of the lever, on the frame (2)and this would lock the door in the close position.   The assembly is fitted into the door hole which can be a square, round or rectangular and then is locked into position by four moldings 5 & 6 in FIG. 1, also shown as 5,6,8,& 9 in FIG.5, connected by bolts or screws to the two frames, (on the inside part of the door) on top, bottom and sides, forming a picture frame-like design around the door window (as seen from the inside).
