    DETAILED DESCRIPTION OF THE INVENTION

    [0022] With reference now to the drawing, and in particular to FIGS. 1 through 13 thereof, the door stopper, embodying the principles and concepts of the present invention will be described.

    [0023] Referring now to FIG. 1, a first embodiment of the door stopper is shown generally at 10. The door stopper has two telescoping bar portions 12 and 14, with the portion 14 sliding into the portion 12, so the bar can adjust to different door widths. A locking portion 16 is used to lock the telescoping bar into the desired position. Attached at each end of the bar are posts 18. Feet 20 are connected to each post 18, the feet conforming to the frame to prevent the door from opening inwardly into the room. This embodiment fits doors 32-44 inches wide and secures doors which open inward into a classroom. To accommodate the different door frame sizes, there are six different sizes of posts.

    To use the door stopper you: [0024] 1. Place the device footers flat on the floor, footers facing the door, with the locking knob facing towards you. [0025] 2. Push the device footers under the door so that the posts on the end of each side of the device remain in direct contact with the door. [0026] 3. Slightly unscrew, turn to left, the knob so that the connecting pole is unsecured which will allow you to stretch the device left and right to become secured into the door frame. [0027] 4. Turn the locking knob to the right until the device is locked. [0028] 5. Pull on the door handle/door knob to make sure all installation steps have been completed correctly and the door has been properly secured.

    [0029] Referring now to FIG. 2, a universal version of the door stopper is shown, which can fit many different door frames. The posts 18 are designed so that different feet 20 can be removably attached, each foot designed for a different frame type. A second embodiment of the door stopper provides a universal door frame fit. FIG. 2 shows the telescoping bar sections, each connected to a door footer, and a pair of universal posts connected to each door footer. The device functions the same as the first embodiment. With the device telescoped to its narrowest width, the device is sat on the floor and slide under the door.

    [0030] Referring now to FIG. 3, the invention is shown with the feet slide under the door, but before the bar is adjusted so that the fee are slide into contact with the door frame.

    [0031] Referring now to FIG. 4, the invention is shown with the bar adjusted so that the feet are in contact with the door frame. The telescoping bar is slide as wide as it can go and locked into place with the lock screw.

    [0032] Referring now to FIG. 5, a top view of the invention is shown before the feet are slide under the door. The door stopper is telescoped as wide as it can go.

    [0033] Referring now to FIG. 6, the invention is shown from outside the room, with the feet slide against the frame to prevent the door from opening inwardly. The view from outside the classroom is shown, with the feet engaged to the door frame, to hold the barricade bar tight against the door and to prevent the door from opening inward into the classroom.

    [0034] Referring now to FIG. 7, a third embodiment of the invention is shown, for outwardly opening doors. This embodiment has a plate which is permanently connected to the door with a pair of rails which are sized to allow the door stop portion to slide into the rails and fit snuggly against the doorframe. When in place this embodiment stops a door from opening outwardly.

    [0035] Referring now to FIG. 8, a different view of the invention of FIG. 7 is shown.

    [0036] Referring now to FIG. 9, the plate of FIG. 7 is shown attached to the side of the door inside the room.

    [0037] Referring now to FIG. 10, the door stopper portion is shown partially slide onto the rails of the plate.

    [0038] Referring now to FIG. 11, the invention is shown with the door partially open.

    [0039] Therefore, the foregoing is considered as illustrative only of the principles of the apparatus of a shape memory artificial bait. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
