The disclosure and prior art relates to door hardware assemblies and more particularly pertains to a new door hardware assembly for securing a door in closed configuration.
An embodiment of the disclosure meets the needs presented above by generally comprising a mortice lock that is coupled to a door. The mortice lock comprises a latch bolt, which in turn comprises a head and a shaft. The head is circumferentially larger than the shaft. A strike plate is mounted to a doorframe in which the door is positioned. A channel extends into the door from an interior surface of the door so that the head of the latch bolt is positioned between the doorframe and the channel when the latch bolt is extended through the strike plate. A rod is selectively insertable into the channel. The rod is positioned to abut the head of the latch bolt to prevent the latch bolt from retracting from the strike plate, thereby rendering the door unlockable from either side of the door.
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
A channel 22 extends into the door from an interior surface of the door, as shown in
A rod 30 is selectively insertable into the channel 22, as shown in
A plate 32 is coupled to a first end 34 of the rod 30, as shown in
A pin 36 is coupled to and selectively extensible from the rod 30, as shown in
The assembly 10 also comprises a plug 42 that is complementary to an opening 44 of the channel 22. The opening 44 is positioned to selectively insert the plug 42 to close the channel 22.
In use during the crisis, the user inserts the rod 30 into the channel 22, preventing retraction of the latch bolt 14 from the strike plate 20, thereby rendering the door unlockable from either side.
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 element is present, unless the context clearly requires that there be only one of the elements.
