ABSTRACT:
BACKGROUND OF THE INVENTION
I. Field of the Invention
The present invention relates generally to the field of sound deadening equipment. More particularly, the invention comprises a cough silencer device.
In general, a first field of use of the disclosed invention is by hunters, as the most likely benefactors of the unique advantages of the instant invention. However, many other fields, such as for use by enraged persons, bird watchers, audience members and the like, could find potentially beneficial uses of this invention.
Thus, it can be seen that the potential fields of use for this invention are myriad and the particular preferred embodiments described herein is in no way meant to limit the use of the invention to the particular field chosen for exposition of the details of the invention.
A comprehensive listing of all the possible fields to which this invention may be applied is limited only by the imagination and is, therefore, not provided herein. Some of the more obvious applications are mentioned in the interest of providing a full and complete disclosure of the unique properties of this previously unknown general purpose article of manufacture. It is to be understood from the outset that the scope of this invention is not limited to these fields or to the specific examples of potential uses presented herein.
II. Description of the Related Art
Various devices are well known in the prior art which deal with muffling sounds. These devices can be placed over the mouth and into which a person may yell, scream, cough or sneeze, so as to deaden such sounds. However, no one patent fully shows each and every aspect of the invention.
Sound deadening equipment are shown in U.S. Pat. No. 3,796,842 issued to Eric L. Guille on Mar. 12, 1974; U.S. Pat. No. 4,396,089 issued to Monya Scully on Aug. 2, 1983; U.S. Pat. No. 4,834,212 issued to Moira J. Figone et al. on May 30, 1989; U.S. Pat. No. 4,932,495 issued to Dewey R. Chapman on Jun. 12, 1990; U.S. Pat. No. 5,413,094 issued to Edward McBrearty on May 9, 1995; and U.S. Pat. No. 5,434,974 issued to Tien-Chu Hsueh on Jul. 18,1995.
U.S. Pat. No. 3,796,842 to Guille discloses a dictation mask. The dictation mask adaptable for use by a court reporter, or the like, is electrically connected to a recording apparatus for recording the voice of the dictator. A generally spherically-shaped member provides an area for fitting on the face of the dictator and includes a plurality of chambers serially in communication by means of sole apertures. Certain of the chambers have muffling coils mounted therein for receiving the breath and voice of the dictator and muffles the sound therefrom. Each such muffling coil is provided with a plurality of spaced-apart breath exhaust passages. The spherically-shaped member is provided with a handle. The handle provides one of the plurality of chambers. The dictation mask includes a moisture-absorbing means.
U.S. Pat. No. 4,396,089 to Scully discloses a sound muffling cup. The invention is directed to provided a sound muffling cup into which an enraged person can shout to release tension while avoiding disturbing other persons. The cup comprises an elongated body portion having a substantially closed end wall at one end, and brim shaped to provide a mouthpiece at the other end. The body portion is of a size such that the fingers can be at least partially wrapped around the body portion for holding of the cup, and the mouthpiece is of a size and contour such that it can be placed over the mouth with substantially the entire brim contacting the skin along a generally elliptical line spaced from the lips and on the mouth side of the nose and chin.
U.S. Pat. No. 4,834,212 to Figone et al. discloses a sound muffler for covering the mouth. It is ahuman sound muffler and indicator for placement around the mouth of a user to absorb most of the sound emanating from the user's mouth. It includes a microphone and associated electrical circuit for receiving unabsorbed sound and provides an indication of the intensity of the unabsorbed sound.
U.S. Pat. No. 4,932,495 to Chapman discloses a vocal sound muffling device. The vocal sound muffling device having an elongated tubular body provides an elongate tubular cavity. A mouthpiece on one end of the body provides an inlet into the cavity for vocal sound waves and atomized fluids. A closure on the other end of the body having a fluid outlet therein is for regulating fluid flow from the cavity. Cellular material is in the cavity intermediate the inlet and outlet for attenuating the vocal sound waves.
U.S. Pat. No. 5,413,094 to McBrearty discloses an apparatus for reducing the noise of coughs and sneezes. The apparatus for reducing the noise of coughs and sneezes is placed over the nose and mouth of the user. The apparatus has a core with a recessed portion to fit over the mouth and nose of the user and the core is made of a noise reducing material. A cover surrounds the core and has a section of absorbent material positioned over the recessed portion of the core. The noise reducing material of the core is a foamed resin. Vent holes are provided on the cover to allow the air forced into the core to exit the core and for the removal of moisture. A strap is attached to the cover to allow the user to wear the apparatus about the user's person until upon need, the apparatus is placed over the mouth and nose to reduce the noise of a cough or sneeze.
U.S. Pat. No. 5,434,374 to Hsueh discloses a detachable filter and muffler device. This invention relates to the detachable filter and muffler device used in an exhaust system. The filter and muffler device is easily detachable so that the maintenance of the exhaust system is simplified, and the cost of maintenance is reduced.
The present invention is completely different than these patents in that it consists of a cough silencer device. The invention concerns a device for use by hunters in the woods so that if the hunter has to cough while hunting, a portion of the device would be put to the hunter's mouth and, upon coughing, the cough noise would be silenced by the device. The device comprises three main parts, a body, an internal muffling baffling system and an end cap. There is an alternative embodiment, being an elongate tube and mouthpiece attached thereto.
None of the above inventions and patents, taken either singly or in combination, is seen to describe the instant invention as claimed. Accordingly, the invention a cough silencer device will overcome the shortcomings of the prior art devices.
SUMMARY OF THE INVENTION
In accordance with the present invention and the contemplated problems which have and continue to exist in this field, the present invention refers to a cough silencer device that consists of three major parts. The first part is the body of the device, the second part is the internal muffling baffling system and the third part is the end cap, which willows access to the internal parts of the device, so as to be taken apart for cleaning. An alternative fourth part is an elongate tube and mouthpiece. Obviously, a mouth portion of the body itself is put to the hunter's mouth so that the hunter may cough into the mouth portion, thereby silencing the cough to prevent noise escaping and scaring the game away. The baffling system is for reducing sound. It is contemplated that the baffling system will have a fibrous material (such as cotton) interspaced between baffling discs to assist in silencing the noise. Since the fibrous material is removable, the device could be used with or without the fibrous material. The elongate tube and mouthpiece is an alternative embodiment, typically for use by bow hunters, inasmuch as a bow hunter is utilizing both hands normally at the same time and is not able to place the mouth portion to the mouth at desired times. Essentially, the device would be affixed to the upper garment of the bow hunter. The elongate tube would be placed against the garment and secured thereto so that the mouthpiece is positioned near the mouth of the hunter. This allows the bow hunter to tur
