DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention pertains to a device for providing air in emergency situations, and particularly to a device which includes a decorative and/or functional feature so that the device can be attractively located in any environment.
2. Description of the Relevant Art
Hall U.S. Pat. No. 4,637,387 discloses a breathing apparatus having a mask operatively connected to a cylinder. Hall fails to disclose a breathing apparatus having a mouthpiece member for providing airflow to the user thereof, and a decorative front portion for aesthetically-pleasing display thereof in a variety of locations.
Williamson U.S. Pat. No. 4,996,982 discloses a portable emergency breathing apparatus having a mouthpiece, regulator, and air storage container, but fails to disclose a breathing apparatus having a decorative front portion for open, inconspicuous display thereof in a variety of settings, and means for indicating its location in darkness.
Spergel U.S. Pat. No. 4,440,163 discloses an emergency breathing apparatus which attaches to an air cylinder, but fails to disclose an emergency breathing apparatus having a decorative front portion suitable for tactful display in a variety of settings; and means for illuminating the device in darkness.
Hanson U.S. Pat. No. 4,078,561 discloses a helmet having an air supply container attached thereto. Hanson fails to disclose an emergency breathing apparatus which is adapted to be conveniently yet inconspicuously displayed in a variety of settings and which includes a visual indicator for easily locating the device in darkness.
Huang U.S. Pat. No. 5,243,972 discloses a portable mask which cooperates with an oxygen tank for supplying oxygen thereto, but fails to disclose a breathing device which doubles at a home decoration when not in use, including a visual indicator for quickly identifying its location in darkness.
There are known portable aerosol inhalers which provide doses of pressurized liquid medicine, such a Primatene.RTM. Mist Asthma Inhaler. Such devices fail to provide air or oxygen, are not suited as a home decoration when not in use as a medicinal device, and do not include means for indicating its location.
SUMMARY OF THE INVENTION
The terms "air" and "gas" as used herein are intended to mean any substance which can be safely breathed by a human being, including, but not limited to oxygen, air oxygen-rich air, purified air, filtered air, and noxious or smoke-filled air from which noxious substances and/or smoke have been substantially removed.
The invention provides a device being a simple and effective means for supplying air or oxygen in emergency situations, and being usable as a home-like decoration when not used as a breathing device.
A first embodiment provides a breathing apparatus for emergency situations, including a storage container having air or oxygen under pressure; a mouthpiece which is connected to the air container; an actuator which cooperates with the air container and the mouthpiece to selectively permit fluid communication therebetween; a decorative front surface for allowing the device to be conveniently located in a wide variety of settings, and audio and visual elements for easy accessibility of the device in a dark or smoke-filled environment.
In an emergency, the mouthpiece is inserted into the user's mouth, and air is discharged from the pressurized air container by activating the actuator. The device is preferably, but not necessarily, held in place solely by the mouthpiece, thereby leaving the hands substantially free for other emergency-related acts. The activation of airflow from the device is initiated by finger or mouth movement of the actuator. Air or oxygen is discharged from the container in a substantially continuous flow, or in bursts having predetermined duration and/or frequency.
When not in use in an emergency, the device is preferably decoratively situated in virtually any setting, by resting the device on a horizontal surface or by suspending it along a vertical surface so that it
