Abstract

A portable door alarm including a front component connected to a rear component by a connecting component, the connecting component configured to be positioned at an edge of a door such as between a floor and a bottom edge of a door to which the alarm is associated so that the front component is positioned on a first side of the door and the rear component is positioned on an opposite side of the door, the rear component including an optical motion sensor configured to detect movement of the door. In one aspect the alarm is configured to fit upon a bottom edge of the door and to slide with the door as the door is opened or closed. In other aspects the front component includes an indicator and the rear component may include a variety of electrical components for various operational features. Various methods of operation are also provided.

Claims

1. A portable door alarm comprising:

a front component including an indicator;

a rear component including a motion sensor and a battery which powers said portable door alarm; and

a connecting component connecting said front component to said rear component, said front component, said rear component and said connecting component defining a gap which receives an exterior edge of a door to which said alarm can be engaged.

3. The alarm of claim 1 where said indicator includes a light.

4. The alarm of claim 1 where said motion sensor is an optical motion sensor.

5. The alarm of claim 1 where said connecting component includes an electrical connection electrically connecting said indicator to circuitry of said rear component.

6. The alarm of claim 1 where said connecting component includes a flat bottom side configured to slide along a floor, said flat bottom side having a length measuring greater than a height of said rear component.

7. The alarm of claim 1 where said indicator is configured to turn on upon opening of a door which said alarm is engaged.

8. The alarm of claim 1 further comprising a controller configured to send a signal to said indicator upon opening of the door.

9. The alarm of claim 8 where said alarm is configured to send a wireless signal to a receiver to notify of opening of the door.

10. The alarm of claim 1 where said rear component is configured to be adjusted upon said connecting component to vary the gap.

18. The alarm of claim 1 further comprising a smoke detector positioned at said rear component.

19. The alarm of claim 1 further comprising a camera and configured to send an image in the form of wireless signal, said camera configured to activate upon motion of the door.

20. The alarm of claim 1 configured to send video images.

21. The alarm of claim 1 where said rear component includes a controller configured to activate said indicator.

2. A portable door alarm comprising:

a front component including an indicator, said front component configured to be positioned at an outside side of a door;

a rear component including a motion sensor, said rear component configured to be positioned at a side opposite the outside side; and

a connecting component connecting said front component to said rear component, said front component, said rear component and said connecting component defining a gap which receives an exterior edge of a door to which said alarm may be engaged and where said connecting component is configured to be positioned between a floor and a bottom edge of a door.

11. A door alarm comprising:

a front component including an indicator; and

a rear component having a battery which powers said door alarm, said rear component connected to said front component by a connecting component, said rear component and said front component configured to be positioned on opposite sides of a door to which said alarm is engaged, said indicator electrically connected to said rear component.

12. The alarm of claim 11 where said connecting component is configured to be positioned between a floor and a bottom edge of a door to which said alarm connects.

16. A method of setting a door alarm comprising straddling an exterior edge of the door with said device of claim 11.

13. A door alarm comprising:

a front component including an indicator; and

a rear component connected to said front component by a connecting component, said rear component and said front component configured to be positioned on opposite sides of a door to which said alarm is engaged, said indicator electrically connected to said rear component where said rear component includes a controller configured to activate said indicator upon opening of the door.

14. The alarm of claim 13 where said controller includes a processor and a memory, said memory configured to store data pertaining to an alarm event.

15. The alarm of claim 14 further comprising a receiver/transmitter configured to send and/or receive wireless signal data.

17. A portable door alarm comprising:

a front component configured to be positioned at an outside of a door, said front component having an indicator and adjustably connected to a rear component by a connecting component, said connecting component configured to be positioned at an edge of a door to which said alarm is associated so that said front component is positioned on a first side of the door and said rear component is positioned on an opposite side of the door, said rear component including a speaker and including a motion sensor configured to detect movement of the door in order to activate said indicator and also to activate said speaker.
