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.

Claims

1. An intruder alarm device comprising:

an outer casing,

means for mounting the outer casing to a vertical surface,

detection means for detecting if an individual enters a room in which the intruder alarm device is located and activated,

notification means for notifying a homeowner that an individual has walked into a room in which the intruder alarm device is located,

wherein the vertical surface further comprises a door frame, said door frame being located immediately adjacent to a door,

wherein the outer casing has a rectangular or cubical shape,

wherein the means for mounting the outer casing to a vertical surface further comprises;

a quartet of external mounts, wherein each external mount is attached to the outer casing,

a plurality of fastening devices, wherein a fastening device is used to attach each external mount to the vertical surface,

wherein the detection means for detecting if an individual enters a room in which the intruder alarm device is located further comprises;

a slot located on the outer casing,

a trigger axially attached within the outer casing, the trigger extending outward through the slot, said trigger having an extendible range from a vertical position to a horizontal position, wherein the trigger is in a disarmed state when the trigger is in a vertical position, further wherein the trigger is in an armed state when the trigger is in a horizontal position,

a central processing unit located within the outer casing,

power means for providing power to the central processing unit,

an internal alarm located within the outer casing, the internal alarm being connected to the central processing unit, and

means for activating the internal alarm responsive to when the trigger in the horizontal position is being pushed by a door against a side of the slot on the outer casing.

2. An intruder alarm device according to claim 1 wherein the power means for providing power to the central processing unit further comprises at least one battery located within the outer casing.

3. An intruder alarm device according to claim 2 wherein the notification means for notifying a homeowner that an individual has walked into a room in which the intruder alarm device is located further comprises

(a) a speaker located within the outer casing, the speaker being connected to the internal alarm,

(b) a plurality of holes located on the outer casing immediately adjacent to the speaker,

(c) wherein the speaker makes sounds that are heard through the plurality of holes if the internal alarm is activated.

4. An intruder alarm device according to claim 3 wherein the means for activating the internal alarm further comprises:

(d) a first contact located on the trigger, the first contact being connected to the central processing unit,

(e) a second contact located on the outer casing, the second contact being connected to the central process unit,

(f) wherein the first contact is immediately adjacent to the second contact when the trigger is in a horizontal position,

(g) wherein the door, when opened and pushed against the trigger, causes the first contact to be forced into contact with the second contact, thereby completing a circuit in between the battery and the internal alarm, thereby activating the internal alarm.

5. An intruder alarm device comprising:

(a) an outer casing, the outer casing having a rectangular or cubical shape,

(b) means for mounting the outer casing to a vertical surface, said vertical surface further comprising a door frame, said door frame being located immediately adjacent to a door, said means further comprising (i) a quartet of external mounts, wherein each external mount is attached to the outer casing, (ii) a plurality of fastening devices, (iii) wherein a fastening device is used to attach each external mount to the vertical surface,

(c) detection means for detecting if an individual enters a room in which the intruder alarm device is located and activated, said detection means further comprising (i) a slot located on the outer casing, (ii) a trigger axially attached within the outer casing, the trigger extending outward through the slot, said trigger having an extendible range from a vertical position to a horizontal position, wherein the trigger is in a disarmed state when the trigger is in a vertical position, further wherein the trigger is in an armed state when the trigger is in a horizontal position, (iii) a central processing unit located within the outer casing, (iv) power means for providing power to the central processing unit, said power means further comprising at least one battery located within the outer casing, (v) an internal alarm located within the outer casing, the internal alarm being connected to the central processing unit, and (vi) means for activating the internal alarm, said means further comprising (1) a first contact located on the trigger, the first contact being connected to the central processing unit, (2) a second contact located on a side of the slot on the outer casing, the second contact being connected to the central process unit, (3) wherein the first contact is immediately adjacent to the second contact when the trigger is in a horizontal position, (4) wherein a door, when opened and pushed against the trigger, causes the first contact to be forced into contact with the second contact, thereby completing a circuit in between the battery and the internal alarm, thereby activating the internal alarm and,

(d) notification means for notifying a homeowner that an individual has walked into a room in which the intruder alarm device is located, said notification means further comprising (i) a speaker located within the outer casing, the speaker being connected to the internal alarm, (ii) a plurality of holes located on the outer casing immediately adjacent to the speaker, (iii) wherein the speaker makes sounds that are heard through the plurality of holes if the internal alarm is activated.
