Weekly Invention by InventionHome.com – Pet Door Fire Exit

InventionHome announces their Invention of the Week – “Pet Door Fire Exit”.

Independent inventor Tom Kodat enlisted the help of InventionHome to assist him in finding marketing/licensing opportunities for his invention.

Pet Door Fire Exit allows a pet the ability to move outside the home without assistance from the owner, in the event of an emergency. The exit also allows the homeowner to release the animal before getting out of a car so that the pet can protect the owner as he moves to the house from the car. Pet Door Fire Exit consists of an electronic pet door with an internal RF transceiver, speaker, and digital recorder/player. The other main parts are a smoke detector with an internal RF transceiver, a handheld RF remote control, and pet collars with internal RF transmitters. The smoke detector, similar in appearance to a regular smoke detector, has an internal radio frequency (RF) transceiver operating at 900MHz or 2.4GHz. The frame of the electronic pet door would contain a digital voice recorder/player, a speaker, and an RF transceiver like the one in the smoke detector. Normally, a 12-volt converter at the nearest receptacle to the door will provide power. Both the smoke detector and the pet door could also contain rechargeable batteries so the devices could still function if the power is off. A handheld or keychain remote control can communicate with the transceiver in the pet doorframe, permitting the user to unlock the pet door, as desired. Pet collars with RF transmitters and devices that could open a screen or storm door such as a rod screw actuator and a replacement storm door handle with a 12-volt DC solenoid inside are also products used in this invention. The pet door could have a manual lock or latch so that it could function as a standard type of pet door. The PDFE smoke detector could replace an existing smoke detector in a home or could be installed in a different location. If the smoke detector senses smoke, it will signal the pet door by RF communication, causing the pet door to unlock and play the voice recording calling the pet(s) to the door. If unlocked by the smoke detector, all pet(s) will be able to exit but not re-enter. Pressing the "test" button on the smoke detector should unlock the pet door and activate playback of the voice recording calling the pet(s). Because the smoke detector and the electronic pet door are communicating by RF transmission, the pet door could direct the smoke detector to silence the alarm tone for some period of time (20 seconds for example) to ensure that the pet(s) can hear the voice playback. Without the voice-recording playback, the pet(s) would not know that the pet door is unlocked and that they are wanted outside. The PDFE handheld or keychain remote control will also cause the pet door to unlock and play the voice recording. In addition to being operated by the smoke detector or the remote control, the pet door RF transceiver could recognize pet collars with compatible RF transmitters. This could also be done with passive RFID tags in the collars and an RFID reader in the electronic pet door. The pet collars would allow the pet door to differentiate between pets so access through the door could be limited to just those with the compatible collar. One or more LEDs on the electronic pet door frame could indicate to the owner if the pet is inside or out if there is only one pet and if a battery in a pet collar needs to be replaced. The PDFE smoke detector is also made to sense and trigger in the event of high levels of carbon monoxide.

I can't believe this hasn't hit the market yet. I've googled all over for just such a mechanism for my beloved dogs. Is there any further information available anywhere concerning this invention's commercial availability?

I had this idea over 15 years ago when my neighbor's cats burned in a house fire while I was training to become a firefighter, but did not know how to make it happen with the available technology at the time. Do you know who is currently manufacturing this system? I would be very interested in becoming a distributor/ installation company.

Still looking for this product. Almost 5 years later... nothing.
Too bad, because its a terrific idea!
