Abstract

A portable door locking system includes a door that is hingedly positioned in a door jamb and the door includes a hinge. A locking unit is provided and the locking unit is selectively coupled to the hinge. The locking unit extends laterally between the door and the door jamb. In this way the door abuts the locking unit when the door is urged into an open position. The locking unit inhibits the door from being opened to inhibit an intruder from entering the room.

Claims

1. A portable door restraining system comprising:

a door being hingedly positioned in a door jamb, said door having a hinge and a first surface, said first surface facing into a room;

a locking unit being selectively coupled to said hinge, said locking unit extending laterally between said door and said door jamb such that said door abuts said locking unit when said door is urged into an open position, said locking unit inhibiting said door from being opened wherein said locking unit is configured to inhibit an intruder from entering said room, said locking unit comprising

a restraint having a central member having a front side;

a saddle; and

a screw extending through said central member and rotatably engaging said saddle such that said restraint is rotatably coupled to said saddle, said screw having a head, said head being exposed on said front side of said central member.

2. The system according to claim 1, wherein said saddle includes a first surface, a second surface, a first end and a second end, said saddle being concavely arcuate between said first end and said second end such that said first end is spaced from said second end thereby facilitating said saddle to removably engage said hinge.

3. The system according to claim 2, further comprising said restraint having a first arm and a second arm, said central member having a first lateral side, a second lateral side, and a back side, said first surface of said saddle being positioned on said back side of said central member.

4. The system according to claim 3, further comprising said first arm extending outwardly from said first lateral side, said second arm extending outwardly from said second lateral side, said first arm abutting said door jamb when said saddle is positioned on said hinge, said second arm abutting said first surface of said door when said saddle is positioned on said hinge.

5. The system according to claim 1, wherein said head has a pair of slots extending toward said saddle, said slots being oriented perpendicular with each other such that said pair of slots forms a plus.

6. The system according to claim 5, further comprising a key being configured to be manipulated, said key having a handle and a shaft, said shaft having a pair of intersection walls such that said shaft forms a plus corresponding to said slots in said screw.

7. The system according to claim 6, wherein:

said restraint having a first arm and a second arm; and

said key selectively urges said restraint into a locking position having each of said first arm and said second arm being horizontally oriented such that said first surface of said door engages said second arm to inhibit said door being opened.

8. The system according to claim 7, wherein said key selectively urges said restraint into an unlocked position having each of said first arm and said second arm being vertically oriented such that said second arm does not engage said first surface of said door to facilitate said door to be opened.

9. A portable door locking system comprising:

a door being hingedly positioned in a door jamb, said door having a hinge and a first surface, said first surface facing into a room; and

a locking unit being selectively coupled to said hinge, said locking unit extending laterally between said door and said door jamb such that said door abuts said locking unit when said door is urged into an open position, said locking unit inhibiting said door from being opened wherein said locking unit is configured to inhibit an intruder from entering said room, said locking unit comprising;

a saddle having a first surface, a second surface, a first end and a second end, said saddle being concavely arcuate between said first end and said second end such that said first end is spaced from said second end thereby facilitating said saddle to removably engage said hinge,

a restraint having a central member, a first arm and a second arm, said central member having a first lateral side, a second lateral side, a front side and a back side, said first surface of said saddle being positioned on said back side of said central member, said first arm extending outwardly from said first lateral side, said second arm extending outwardly from said second lateral side, said first arm abutting said door jamb when said saddle is positioned on said hinge, said second arm abutting said first surface of said door when said saddle is positioned on said hinge,

a screw extending through said central member and rotatably engaging said saddle such that said restraint is rotatably coupled to said saddle, said screw having a head, said head being exposed on said front side of said central member, said head having a pair of slots extending toward said saddle, said slots being oriented perpendicular with each other such that said pair of slots forms a plus, and

a key being configured to be manipulated, said key having a handle and a shaft, said shaft having a pair of intersection walls such that said shaft forms a plus corresponding to said slots in said screw, said key selectively urging said restraint into a locking position having each of said first arm and said second arm being horizontally oriented such that said first surface of said door engages said second arm to inhibit said door being opened, said key selectively urging said restraint into an unlocked position having each of said first arm and said second arm being vertically oriented such that said second arm does not engage said first surface of said door to facilitate said door to be opened.
