Door barricade system

Abstract

Method and apparatus for a safety door barricade for use with a door of a school room or the like. It is made of a single piece of angle iron having a base portion and a back portion disposed 90 degrees apart with a curved handle extending from the surface of the base portion to the back portion along with a downwardly extending rod which is designed for insertion into a hole disposed in the surface of the floor adjacent the door just inside the door. When the device is in inserted in its safety barricade position, and the door is opened against the back plate of the device, a barricade is provided. When the device is not in its safety barricade position, it is placed into an adjacent hole in the floor next to the door wherein the safety device can be stored in an unobtrusive location.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(9) The following discussion describes in detail at least one embodiment of the present invention. This discussion should not be construed, however, as limiting the present invention to the particular embodiments described herein since practitioners skilled in the art will recognize numerous other embodiments as well. For a definition of the complete scope of the invention the reader is directed to the appended claims. FIGS. 1 through 6 illustrate the present invention wherein a safety door barricade for a school room door is disclosed and which is generally indicated by reference number 10.

(10) Turning to FIG. 1, therein is shown the present invention 10 placed into a hole 12 of the floor 14 of a school room, or the like, so that it is aligned with the space or gap 16 between the inner edge of the door frame or jamb 18 and the corresponding edge of the door 20 wherein the door is mounted onto the wall 22 in the conventional manner using a plurality of hinges 24 along with having a conventional door knob 26. The door 20 is hung to swing inwardly so that its bottom edge passes over a path overlying hole 12. Therefore, when the door is opened the present invention 10 which is anchored and interlocked with the floor 14 acts as a barricade by engaging against the bottom 28 of the door 20. The present invention 10 is made of a piece of angle iron 29 or the like having a horizontal base portion 30 and a vertical back portion 32 disposed perpendicular to each other and having a pull handle 34 being curved to extend between the base portion 30 and back portion 32 of the present invention 10 so that a user can grasp the handle 34 of the present invention in order to remove the present invention from the hole 12 or replace it in the hole. The present invention 10 has a spike or rod 36 extending downwardly from the bottom surface of the base 30 thereof for easy insertion and removal from the hole 12. The present invention 10 is attached to the wall 22 using a tether 38 extending from the present invention 10 to a connector 40 securely disposed on the wall 22. When not in use, the present invention 10 is disposed in a second hole 42 placed in the concrete floor 14 proximate the first hole 12 so that the present invention 10 can be stored in an out of the way location so as to not to interfere with traffic passing through the door 14 and the entryway 64 of the door.

(11) Turning to FIG. 2, therein is shown the present invention 10 showing the angle iron 29 along with the base 30, the back 32, handle 34 and downwardly extending spike 36 which passes through a receptacle 44 for insertion into the hole 12 of the concrete floor wherein the receptacle 44 forms a receiver having a rim 46 around its upper end for stopping and fitting against the upper surface of the hole 12 in the floor so that the receptacle can be easily retrieved from the hole 12. Also shown is a central aperture 48 in the receptacle 44 for receiving the spike 36 from the bottom of the base 30 of the present invention 10.

(12) Turning to FIGS. 3 through 5, therein are shown various traditional views of the present invention 10 showing the elements of the present invention as previously disclosed. FIG. 3 shows finger 62 of a hand of a user in place to lift the pull handle 34 of the present invention 10 by passing through space 60 between the handle and the back portion 32.

(13) Turning to FIG. 6, therein is shown a cross sectional view of the receptacle 44 showing its rim 46 along with its aperture 48 and a bottom 50 of the receptacle which prevents the hole 12 from filling up with dirt so that the receptacle 44 can be removed and cleaned on an as needed basis.

(14) The present invention 10 is designed to barricade a door 20 and keep it from opening when necessary to prevent unauthorized opening and is fabricated from a metal angle bracket 29 with a bent metal round bar welded to it to form a handle 34. The bent section of the round bar is used as a pull handle 34 and the lower part of the round bar projects through an aperture 66 out of the bottom of the angle bracket to form a spike or rod 36. Rod 36 is welded only to the back 32 of angle iron 29 leaving it free to flex slightly at its passageway through aperture 66 if the door 20 is pushed on very hard so that great force is applied from its outside toward its inside. The lower portion 36 of the round bar is designed to insert into a pre-drilled hole 12 in the floor 14 in front of a door 20. When the round bar 36 is inserted into the hole 12 with the flat side of the angle bracket against the door 20 the device 10 will prevent the door from opening. Accordingly, the door 20 is effectively prevented from opening at all or past a predetermined point which point is determined by the positioning of the hole 12 in the floor 14 with respect to the door so long as the door and its hinges 24 do not fail. The present invention 10 can be stored in a second unobtrusive hole 42 adjacent the door frame and then deployed as shown in FIG. 1.

(15) By way of additional summary and by making reference to FIGS. 1-6, the present invention 10 provides a method of assembling a barricade for a door 20 including providing a construction having a base portion 30 and a back portion 32, the base portion having top 52 and bottom 54 surfaces, the back portion having front 56 and rear 58 surfaces, the base portion and the back portion being perpendicular to each other; forming a handle 34 from a bar extending between the top surface of the base portion and the front surface of the back portion, wherein the bar is curved; forming a spike 36 extending perpendicularly away from the bottom surface for insertion into a first hole 12 in a concrete floor 14 adjacent the door so that the bottom surface rests on the concrete floor; and, wherein when the spike is inserted into the hole the rear surface contacts an inner surface of a bottom 28 of the door so as to form a barricade against the door to prevent unauthorized opening of the door. Further, including forming the base portion and the back portion from a continuous one piece structure of material 29 so that they have a flat, rectangular shape and forming the handle or bar 34 and the spike 36 from a continuous one piece structure of material so that they are round in shape, wherein the handle formed by the bar or handle is sized and shaped to provide a space 60 between the bar and the top and front surfaces, wherein the space is sized and shaped to receive a finger 62 of a hand of a user and including a tether 38 for connecting the construction to a surface of a wall 22 adjacent the door for securing the construction to the wall, wherein the construction has a deployed position when the spike is inserted into the first hole and a stored position when the spike is inserted into a second hole 42 in the concrete floor adjacent the door and outside an entryway 64 of the door.
