Abstract

The present invention is a system which will activate an alarm when a garage door is opened. The system in a transmitter unit and a receiver unit. The transmitter unit is attached in proximity to the garage door. The receiver unit is located within a vehicle stored in the garage. The transmitter unit includes a signal generator which activates and transmits radio frequencies (RF) to the second unit. For activation, once the garage door is in an opened position, the transmitter sends a signal to the receiver. The receiver activates an alarm.

Claims

1. A garage door status indicating system used in combination with a garage door, said indicating system comprises:

a contact means is secured to a lower area of a garage door; and

a first device and a second device;

said first device includes a first switch and a transmitter unit;

said first switch is electrically coupled to said transmitter unit;

wherein said first switch is mounted above the garage door and is linearly aligned with said contact means;

said second device includes a receiver unit and a warning means;

said receiver unit is electrically coupled to said warning means;

said second device is used for reminding a user to close the opened garage door; and

said second device is located away from the garage door and in a close proximity to the user'"'"'s active area such that the user could see a warning signal from the warning means easily;

wherein said second device only activated upon the sensed of the presence of the user by a motion sensor;

said transmitter unit includes a transmitting means for transmitting signals and said receiver unit includes a receiving means of receiving said transmitted signals;

said contact means contacts and closes said first switch when said garage door is in an opened position for rendering current to travel to said transmitter unit, said transmitter unit transmits said signals to said receiver unit, and said received signals are received via said receiving means for activating said warning means.

2. A garage door status indicating system as in claim 1 wherein said second device includes a silence push button switch for disabling said warning means.

3. A garage door status indicating system as in claim 1 wherein said second device includes an infrared motion sensor, said infrared motion sensor is coupled to a power source for powering said second device, said infrared motion sensor controls activation of said second device, said second device is activates upon the presence of an individual.

4. A garage door status indicating system as in claim 1 wherein said transmitting means is a signal generator.

5. A garage door status indication system as in claim 1 wherein said receiving means is a radio frequency receiver.

6. A garage door status indication system as in claim 4 wherein said receiving means is a radio frequency receiver.

7. A garage door status indication system as in claim 1, wherein said contact means is a door switch bracket, and said door switch bracket is vertically aligned with said first switch.

8. A garage door status indication system as in claim 1 wherein said contact means is a garage door bracket, and said conventional garage door bracket is vertically aligned with said first switch.

9. A garage door status indicating system used in combination with a garage door, said indicating system comprises:

a first device and a second device;

said first device includes a first switch and a transmitter unit;

said first switch is electrically coupled to said transmitter unit;

said second device includes a receiver unit and a warning means;

said receiver unit is electrically coupled to said warning means;

said second device is used for reminding a user to close the opened garage door; and

said second device is located away from the garage door and in a close proximity to the user'"'"'s active area such that the user could see a warning signal from the warning means easily;

wherein said second device only activated upon the sensed of the presence of the user by a motion sensor;

wherein said second device includes a silence push button switch for disabling said warning means;

said transmitter unit includes a transmitting means for transmitting signals and said receiver unit includes a receiving means of receiving said transmitted signals;

said first switch is secured to a lower area of a garage door frame, said first switch contact the garage door of said garage door frame, contacting said garage door provides for said switch to be in an opened position, and upon opening said garage door said contact switch closes for rendering current to travel to said transmitter unit, said transmitter unit transmits said signals to said receiver unit, and said received signals are received via said receiving means for activating said warning means.

10. A garage door status indicating system as in claim 9 wherein said second device includes an infrared motion sensor, said infrared motion sensor is coupled to a power source for powering said second device, said infrared motion sensor controls activation of said second device, said second device is activates upon the presence of an individual.
