DETAILED DESCRIPTION OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new locking device embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 5, the portable door locking system 10 generally comprises a door 12 is that is hingedly positioned in a door jamb 14. The door 12 has a hinge 16 and a first surface 18 and the first surface 18 faces into a room. The room may be a hotel room, a room in a residence or any other room used for sleeping or the like. The door 12 may be a hinged man door 12 of any conventional size and design. Additionally, the hinge 16 may be a door hinge or the like that has a cylindrical portion.

A locking unit 20 is provided and the locking unit 20 is selectively coupled to the hinge 16. The locking unit 20 extends laterally between the door 12 and the door jamb 14. The door 12 abuts the locking unit 20 when the door 12 is urged into an open position. In this way the locking unit 20 inhibits the door 12 from being opened to inhibit an intruder from entering the room.

The locking unit 20 comprises a saddle 22 that has a first surface 24, a second surface 26, a first end 28 and a second end 30. The saddle 22 is concavely arcuate between the first end 28 and the second end 30 such that the first end 28 is spaced from the second end 30. Each of the first end 28 and the second end 30 are biased toward each other. In this way the saddle 22 frictionally engages the hinge 16 having the second surface 26 of the saddle 22 abutting the hinge 16.

The locking unit 20 further includes a restraint 32 that has a central member 34, a first arm 36 and a second arm 38. The central member 34 has a first lateral side 40, a second lateral side 42, a front side 44 and a back side 46. The first surface 18 of the saddle 22 is positioned on the back side 46 of the central member 34. The first arm 36 extends outwardly from the first lateral side 40 and the second arm 38 extends outwardly from the second lateral side 42.

The first arm 36 abuts the door jamb 14 when the saddle 22 is positioned on the hinge 16. The second arm 38 abuts the first surface 18 of the door 12 when the saddle 22 is positioned on the hinge 16. The restraint 32 is comprised of a rigid material such as titanium or the like. Moreover, the restraint 32 has a bending strength that exceeds the amount of force that can be generated by a human being. In this way the restraint 32 resists being deformed when a human being attempts to urge the door 12 into the open position when the saddle 22 is positioned on the hinge 16.

A screw 48 extends through the central member 34 and rotatably engages the saddle 22. In this way the restraint 32 is rotatably coupled to the saddle 22. The screw 48 has a head 50 and the head 50 is exposed on the front side 44 of the central member 34. Moreover, the head 50 has a pair of slots 52 extending toward the saddle 22. The slots 52 are oriented perpendicular with each other such that the pair of slots 52 forms a plus.

A key 54 is provided and the key 54 is selectively manipulated. The key 54 has a handle 56 and a shaft 58. The shaft 58 has a pair of intersecting walls 60 such that the shaft 58 forms a plus corresponding to the slots 52 in the screw 48. The shaft 58 is selectively inserted into the slots 52 on the screw 48.

The key 54 selectively urges the restraint 32 into a locking position having each of the first arm 36 and the second arm 38 being horizontally oriented. In this way the first surface 18 of the door 12 engages the second arm 38 to inhibit the door 12 being opened. The key 54 selectively urges the restraint 32 into an unlocked position having each of the first arm 36 and the second arm 38 being vertically oriented. Thus, the second arm 38 does not engage the first surface 18 of the door 12 to facilitate the door 12 to be opened.

The locking unit 20 may include a processor, a transceiver, a motor and a power supply. The motor may be mechanically coupled to the screw 48 to selectively rotate the screw 48 thereby selectively urging the restraint 32 between the locking position and the unlocked position. In this way the restraint 32 may be remotely urged between the locking position and the unlocked position. The processor, the transceiver, the motor and the power supply may be in electrical communication with each other. Moreover, the transceiver may be in wireless electrical communication with a remote control.

In an alternative embodiment 62 as shown in FIG. 5, a wedge 64 may be coupled to the central member 34. The wedge 64 may extend laterally beyond each of the first lateral side 40 and the second lateral side 42 of the central member 34. Additionally, the wedge 64 may have a primary surface 66 that may be concavely arcuate with respect to a secondary surface 68 such that the wedge 64 has a semi-circular shape.

In use, the saddle 22 is removably coupled to the hinge 16. The key 54 is selectively inserted into the slots 52 in the screw 48 and the screw 48 is rotated to position the restraint 32 into the locking position. Thus, the restraint 32 inhibits the door 12 from being opened thereby enhancing security of the room. The key 54 is selectively inserted into the slots 52 on the screw 48 and the screw 48 is rotated to position the restraint 32 into the unlocked position. In this way the restraint 32 facilitates the door 12 to be opened. The saddle 22 is removed from the hinge 16 at any selected time.

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, system 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.
