The disclosure relates to security assemblies and more particularly pertains to a new security assembly for blockading a door in a lockdown situation.
The prior art relates to security assemblies. Prior art security assemblies for doors many comprise devices that attach to opening mechanisms of doors. Prior art security assemblies also may comprise bars that extend past the door jambs of a doorway
An embodiment of the disclosure meets the needs presented above by generally comprising a blockade device. An element of the blockade device is configured to be insertable into a gap defined by a door and a crash bar that is engaged to the door. Each of a pair of fasteners engaged to the blockade device is configured to selectively engage the crash bar, so that the blockade device is reversibly engaged to the crash bar with the element positioned in the gap. The blockade device is configured to prevent actuation of the crash bar so that the door cannot be opened. The fasteners are positioned so that two hands are required to simultaneously disengage the fasteners from the crash bar to enable disengagement of the blockade device from the crash bar.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Each of a pair of fasteners 22, which is engaged to the blockade device 12, is configured to selectively engage the crash bar 16. The blockade device 12 thus is reversibly engaged to the crash bar 16 with the element 18 positioned in the gap 20. The blockade device 12 is configured to prevent actuation of the crash bar 16 so that the door 14 cannot be opened. The present invention is anticipated to be useful in alternative emergency situations where blockade of the door 14 will protect the occupants of the room or the building, such as an active shooter situation in a school, commercial building, and the like.
The fasteners 22 are positioned so that two hands are required to simultaneously disengage the fasteners 22 from the crash bar 16 to enable disengagement of the blockade device 12 from the crash bar 16. Therefore, even if a window 24 of the door 14 is broken, an active shooter exterior to the room or the building would have to reach through the window 24 with both arms and simultaneously manipulate both fasteners 22 to disengage the blockade device 12—a difficult maneuver deterring opening of the door 14.
The blockade device 12 may comprise a plate 26, which has a cutout 28 extending thereinto from a lower edge 30 thereof. The cutout 28 is configured for insertion of the crash bar 16. Concurrently, the plate 26 is inserted into the gap 20. The plate 26 may be sized so that the plate 26 extends past at least one door jamb of a doorway in which the door 14 is positioned, as shown in
The cutout 28 may be biased toward one of opposed ends 32 of the plate 26, as shown in
In one embodiment, as shown in
In another embodiment, as shown in
A knob 50 extends from the front face 48 and through the slot 46. The knob 50 is engaged to the pin 42. The knob 50 is configured to be grasped in digits of a hand of a user, positioning the user to selectively slide the knob 50 within the slot 46 away from the respective opposed side 36 of the cutout 28 to retract the pin 42 into the channel 44. With the pins 42 retracted, the crash bar 16 can be inserted into the cutout 28. Upon release of the knob 50, the pin 42 extends from the channel 44 to engage the lower face 38 of the crash bar 16 to fixedly engage the plate 26 to the crash bar 16 within the gap 20. The plate 26 is configured to prevent actuation of the crash bar 16 so that the door 14 cannot be opened.
The present invention also anticipates the fastener 22 comprising other fastening means, such as, but not limited to, clasps, latches, quick connects, and the like.
In use, the plate 26 is positioned above the crash bar 16 and then lowered so that the crash bar 16 is inserted into the cutout 28 and the plate 26 is inserted into the gap 20 between the crash bar 16 and the door 14. As the plate 26 is lowered onto the crash bar 16, the crash bar 16 deflects the clips 34 to the side. When the plate 26 has been fully lowered, the clips 34 are free to rebound and to engage the lower face 38 of the crash bar 16. The clips 34 are positioned so that two hands are required to simultaneously disengage the clips 34 from the crash bar 16 to enable disengagement of the plate 26 from the crash bar 16.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure 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 disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the elements is present, unless the context clearly requires that there be only one of the elements.
