DETAILED DESCRIPTION OF THE INVENTION

[0022] While the present invention is susceptible of embodiment in various forms, as shown in the drawings, hereinafter will be described the presently preferred embodiments of the invention with the understanding that the present disclosure is to be considered as an exemplification of the invention, and it is not intended to limit the invention to the specific embodiments illustrated.

[0023] With reference to all FIGS. 1-6, the door locking apparatus 100 for locking a door 202 to a surrounding frame 204 includes an integrated plate 102 having a door strike plate 106 coupled to an extension 108, and a shackle 501 or lock 208 fastened to a flexible elongate member 104. The strike plate 106 portion of the integrated plate 102 is configured so as to fasten to the surrounding door frame 204. Specifically, the door strike plate 106 is sized and configured to attach in the recess 800 of the door frame 204. Preferably, and more specifically, the strike plate 106 includes a central aperture 110 and a pair of fastener holes 112A, 112B. In particular, the central aperture 110 is configured to accommodate the bolt of a lock, and the pair of fastener holes 112A, 112B are configured to further secure the attachment of the strike plate 106 to the door frame 204. As illustrated in FIG. 6, the strike plate 106 and related lock components can be installed to the door frame 204 by threadably affixing a pair of threaded fasteners through the pair of fastener holes 112A, 112B over an empty receptacle 600 for receiving the door bolt. The method of installing the strike plate 106 to the door frame 204 may include opening a door 202 hinged to a frame 204 so as to enable the user to attach the strike plate 106 and its lock components in the recess 800 of the frame 204.

[0024] In a preferred embodiment, the central aperture 110 of the strike plate 106 is rectangular in shape. Additionally, the pair of fastener holes 112A, 112B are oriented such that the first fastener hole 112A is arranged proximal to the central aperture 110 and the second fastener hole 112B is arranged distal to the central aperture 110. In the preferred embodiment, the aperture 110 and pair of fastener holes 112A, 112B reside on the same longitudinal axis.

[0025] Moreover, the extension 108 portion of the integrated plate 102 includes a inner portion 401 and an outer portion 402, wherein the extension 108 is adjoined to the door strike plate 106 at its inner portion 401. As illustrated in FIG. 1, the dashed line indicates a boundary between the strike plate 106 and the extension 108, and not any physical feature. Furthermore, the strike plate 106 and extension 108 may be integrated together by being formed from the same structural plate and define the integrated plate 102. Preferably, the integrated plate 102 can be made of any durable structural material. Even more preferably, the integrated plate 102 is composed of steel.

[0026] The extension 108 is shaped to extend past the surrounding frame 204 towards either an outswing direction or outside of the inward-swinging of the door 202 hinged to the door frame 204 when the strike plate 106 is fastened to the frame 204. In a preferred embodiment, and as illustrated in FIG. 1, the strike plate 106 and the extension 108 are coplanar. In another preferred embodiment, and as illustrated in FIGS. 4-6, the inner portion 401 of the extension 108 is shaped to provide an offset 318 between the strike plate 106 and the outer portion 402 of the extension 108. In this embodiment, the offset 318 may be perpendicular to the strike plate 106 and the outer portion 401 of the extension 108. More particularly, the offset 318 section of the extension 108 is coupled at its edges to the adjoining portions of the integrated plate 102 by complementary bends that are configured to follow the contour of the door frame 204, thereby holding the strike plate 106 and the outer portion 401 of the extension 108 in parallel alignment. Thus, the parallel offset configuration of the extension, which is fitted to contours of the frame 204, enables the extension to slip between the door 202 and the frame 204 and extend past the frame 204 towards the outswing direction or outside of the inward-swinging of the hinged door 202. For example, and as best illustrated in FIG. 6, the parallel offset allows the extension 108 to extend towards the outside of the inward-swinging door 502 opposite to its direction of swing.

[0027] Additionally, at least one flexible elongate member 104 extends from the outer portion 401 of the extension 108. In some embodiments, the outer portion 401 of the extension 108 includes at least one opening 114 for attaching to the flexible elongate member 104 or a shackle 501/lock 208, or both, as illustrated in FIG. 5. Preferably, the flexible elongate member 104 has a proximal terminus 406 having a primary closed loop 408 and distal terminus 410 having a terminal closed loop 412. In particular, the flexible elongate member 104 is configured such that the proximal terminus 406, through its primary closed loop 408, mates with the opening 114 of the extension 108. Alternatively, however, and as illustrated in FIGS. 5-6, the flexible elongate member 104 may be fastened to the opening 114 by a fastener. Further, the flexible elongate member 104 is configured such that the distal terminus 410, through its terminal closed loop 412, engages with a lock 208, shackle 501, or the like. More specifically, the terminal closed loop 412 engages with a shackle 501 on a lock 208. Even more specifically, the shackle 501 of the lock 208 passes through the terminal closed loop 412. In preferred embodiments, the lock 208 may include a padlock, combination lock, digital lock, a single-dial lock, a multiple-dial lock, or a key lock. Additional or alterative lock and shackle constructions can be determined by those skilled in the art.

[0028] In a preferred embodiment, the flexible elongate member 104 may be, or may include, a cable. In particular, the flexible elongate member 104 may be a plastic-coated wire rope. Alternatively, in another preferred embodiment, the flexible elongate member 104 may be a chain. Various cable and fastener constructions for providing these capabilities can be selected by those skilled in the art.

[0029] Furthermore, the flexible elongate member 104 is of sufficient length to wrap around a handle (or knob) 700 attached to the door 202 when the door 202 is in a closed position. Preferably, the handle 700 is L-shaped or includes a lever with a laterally extending flange 702. Specifically, when the door locking apparatus 100 is installed to the frame 204, the flexible elongate member 104 can wrap around the laterally extending flange 702 of the lever or L-shaped handle 700 when the door 202 is closed and thereby lock the door 202 to the frame 204. More specifically, and as illustrated in FIG. 2, the shackle 501 or lock 208 passes through the terminal closed loop 412 formed at the distal terminus 410 of the flexible elongate member 104 and an intermediate portion of the flexible elongate member 104 passes through the shackle 501 or lock 208. Alternatively, and as best illustrated in FIG. 5, the shackle 501 or lock 208 passes through the terminal closed loop 412 and affixes to an opening 114 in the extension 108. Accordingly, in both scenarios, the door 202 cannot be opened without unlocking the lock 208 and removing it from the flexible elongate member 104.

[0030] A door 202 may be configured for an internal locking mechanism that latches to the frame 204. The present door locking apparatus 100 provides an improved door locking apparatus and method of use the locking apparatus is most suitable when the internal locking mechanism is not present or inoperable. Advantageously, the locking apparatus provides a provides a temporary locking or security measure until a conventional lock can be installed in the door, at which time the door locking apparatus 100 can easily be removed and reused. Also advantageously, the door locking apparatus 100 provides a lock which secures the door from unwanted entry of unauthorized persons, and is compatible with door handles having a laterally extending flanged arms.

[0031] While a preferred door locking apparatus and methods of use have been illustrated and described, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. Alternative embodiments may be envisioned by those skilled in the art after consideration of the present disclosure. Accordingly, it will be apparent that various modifications can be made without departing from the spirit and scope of the invention. Therefore, having described my invention in such terms such as to enable a person skilled in the art to understand the invention, recreate the invention and practice it, and having presently identified the presently preferred embodiments thereof, I claim:
