## Title
Intruder alarm device

## Abstract

An intruder alarm device that is designed to be mounted on an inside door frame of the front door of a home and sound an alarm, if activated, when the door is opened. The device includes an outer casing that is mounted adjacent to a door and includes a trigger that can be placed immediately in front of the door. If the door is opened while the trigger is in front of the door, the trigger touches a contact within the device and activates an alarm, which then audibly alerts individuals within the home that the door has been opened. The alarm continues to sound until the trigger is returned to vertical position.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIGS. 1 through 7 thereof, a new intruder alarm device 2 embodying the principles and concepts of the present invention and generally designated by the reference numeral 2 will be described.
As best illustrated in FIGS. 1 through 7, the intruder alarm device 2 comprises an outer casing 4 that has four external mounts 6, 7, 8 and 9. The outer casing 4 preferably has a rectangular or cubical shape and is capable of being mounted by fastening devices 10 that are combined with the mounts 6 and 8 to secure the device 2 to a vertical surface 12.
The outer casing 4 also has a slot 14 in it, and furthermore, has a trigger 16 that is axially attached within the outer casing 4. The trigger 16 extends out through the slot 14 and has an extendible range of 90 degrees. The trigger 16 can be anywhere between a vertical position to a horizontal position and extends outward from the outer casing 4 approximately three to four inches. For purposes of this device 2, the trigger 16 is in a disarmed state when the trigger 16 is in a vertical position and in an activated state when the door is opened while the trigger 16 is in a horizontal position.
The device 2 includes an internal central processing unit (CPU) 18 that is preferably powered by a battery 20. Furthermore, the device 2 includes an internal alarm 22 that, when activated, makes a sound that can be heard through speaker 24. Outer casing 4 has a plurality of holes 26 immediately adjacent to the speaker 24, allowing the sounds emitted by the speaker 24 to be heard externally from the device 2. CPU 18 is connected to the alarm 22 through a wire 21, while alarm 22 is connected to speaker 24 via wire 23. Trigger 16 has a contact 28 located on it, while a second contact 30 is located on the outer casing 4. Contact 28 is connected via wire 32 to the CPU 18, while contact 30 is connected to the CPU via wire 34. Contact 28 is immediately adjacent to contact 30 when the trigger 16 is a horizontal, or activated state.
In use, the outer casing 4 of the device 2 is mounted on a door frame 40 immediately adjacent to a door 42. In fact, the portion of the outer casing 4 where the slot 14 is located should be placed flush against a side of the door. If an individual wants to “disarmed” the device 2, he or she need to merely put the trigger 16 in a vertical position, thereby preventing the trigger 16 from being tripped when the door 42 is opened. However, when an individual wants to activate the device 2, he or she can put the trigger 16 in a horizontal, or “armed,” position. Then, once the door 42 is opened, the contact 28 on the trigger will be pushed into the contact 30 on the outer casing 4. Once this occurs, the electrical connection in between the two contacts 28 and 30 will be complete, and the CPU 18, sensing this fact, will notify the alarm 22 to audibly make sounds through the speaker 24. The alarm continues to sound until it is deactivated by returning the trigger 16 to vertical position.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the present vehicle air freshener device to include variations in size, materials, shape, form, function and the 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 the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention 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 invention.
