Description
Fire Safety Doorknob Device Field of the Invention This invention relates to a safety doorknob device. More specifically, the invention is directed to a fire safety doorknob device which sounds an alarm in the case of a fire and also indicates the exit route in a fire situation and in addition, detect the danger of fire on the other side of the door. The device can also be used to detect the danger of carbon monoxide.
to Background of the Invention Fire is the number one killer in the home. Careless smoking, cooking mishaps, faulty wiring and children playing with matches are unfortunately occurances that happen in the home and which lead to fires. Oftentimes the result of 15 such fires is the death of persons. To avoid or to minimize the number of deaths, smoke detectors have been developed in order to detect fires as soon as possible.
Smoke detectors are typically installed on ceilings in areas close to where fires can occur such as in hallways adjourning a kitchen or in bedroom hallways.
While smoke detectors are useful in indicating the presence of smoke 2o suggesting that a fire is present somewhere in the home, they only indicate the presence of smoke via an audible alarm sounding. Oftentimes smoke detectors do not sound until the amount of smoke in the room is already sufficient to blind a person.
Thus one has a difficult time escaping because they cannot see how to exit the room.
In addition, they do not indicate the location of the fire.
25 Doorknob alarm devices are also known as for example that described in U.S.
Patent 5,712,623 and U.S. Patent 4,287,513. Such alarm devices are hung from a doorknob and emit an alarm sound upon detecting that a human body contacts or approaches the doorknob. An alarm that is incorporated into a doorknob is also known and described in U.S. Patent 5,783,995.
3o While such doorknob alarms are useful for personal safety they do not provide any safety with respect to detecting or escaping from a fire.
U.S. Patent 4,540,980 discloses a portable room security alarm mounted to a top of a door which includes a smoke detector alarm, a motion sensing intrusion alarm, a temperature sensing alarm and a digital display alarm clock. This device warns of a fire outside of the door. U.S. Patent 4,442,427 discloses a portable door lock and smoke and intrusion alarm which is actuatable by inward movement and pressure on the door and also by an electrically controlled smoke alarm mounted adjacent it. While both of these devices function to indicate the presence of a fire, they are bulky and require some sort of mounting to a door which is not permanent, nor stable. Furthermore, they provide no clear means to help a person locate the exit and thus get to safety.
There is therefore a need to develop a fire safety device that obviates the deficiencies of the prior art devices and provides a safe and effective means for to detecting and escaping a fire situation.
Summary of the Invention In accordance with the present invention there is provided a novel fire safety doorknob device that detects smoke and indicates the presence of smoke with an audible alarm. In addition, the device of the present invention is readily visible in a smoke filled room such that one can visually see the doorknob device in thick smoke and therefore readily find the location of the door to exit the room.
Moreover, the device of the present invention also provides a means to indicate the presence of a fire on the other side of the door with the provision of a heat sensor in the device.
2o The device of the present invention is provided as a doorknob which is readily installed to any type of door. Alternatively, the device can be simply mounted to a door as a doorknob alone or separately adjacent an existing doorknob. As a doorknob, the device can be provided with or without a key hole or other type of typical door locking mechanism as is known to one skilled in the art.
The device functions to detect smoke and heat and thus the presence of a fire and in response, sound an audible and visual alarm. The visual alarm provides a clear light visible in thick smoke indicating the means of exiting the room. The audible alarm is of such intensity such to alarm a person that a fire is occurnng and can also aid to guide a person to the device and thus the means of escape.
3o The device is designed such that it can be activated from any remote device within a receiving range such as a smoke alarm, heat sensor or carbon monoxide detector or any such combination smoke/carbon monoxide/heat detector. As detected to a carbon monoxide detector the device can be activated in the presence of carbon monoxide. Alternatively, the device can be activated independent of any such remote device. The device in any form can simply be powered using standard batteries.
In accordance with an object of the present invention is a fire safety doorknob device comprising;
- an audible alarm;
- a visual alarm;
- a temperature sensing means; and - receiver means to receive a signal from a remote signaling device, wherein said receiver means activates the audible and visual alarms.
