Description




BACKGROUND OF THE INVENTION




1. Field of the Invention




The present invention relates generally to snorkels and more specifically it relates to a snorkel system for allowing an individual snorkeling to dive beneath the water surface without water entering the breather tube.




2. Description of the Prior Art




Snorkels have been in use for years. Typically, a snorkel is comprised of a mouthpiece that the user inserts into their mouth with a breather tube that is elongate and curved to be positioned upwardly above the head of the user thereby allowing the individual to position their face within the water while still being able to breath freely via the breather tube.




The main problem with conventional snorkel devices is that they accumulate water within the breather tube if the user decides to dive beneath the water surface. Another problem with conventional snorkel devices is that they require the user to purge the water within the breather tube after diving prior to being able to breath utilizing the breather tube.




Examples of patented snorkel related devices which are illustrative of such prior art include U.S. Pat. No. 4,071,024 to Blanc; U.S. Pat. No. 5,267,556 to Feng; U.S. Pat. No. 2,317,237 to Wilen; U.S. Pat. No. 5,239,990 to Delphia; U.S. Pat. No. 3,721,236 to Bardehle; U.S. Pat. No. 5,280,785 to Fujima; U.S. Pat. No. 6,073,626 to Riffe; U.S. Pat. No. 6,129,081 to Wu.




While these devices may be suitable for the particular purpose to which they address, they are not as suitable for allowing an individual snorkeling to dive beneath the water surface without water entering the breather tube. Conventional snorkel devices are not suitable nor designed for allowing an individual to dive beneath the water surface.




In these respects, the snorkel system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of allowing an individual snorkeling to dive beneath the water surface without water entering the breather tube.




SUMMARY OF THE INVENTION




In view of the foregoing disadvantages inherent in the known types of snorkel devices now present in the prior art, the present invention provides a new snorkel system construction wherein the same can be utilized for allowing an individual snorkeling to dive beneath the water surface without water entering the breather tube.




The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new snorkel system that has many of the advantages of the snorkel devices mentioned heretofore and many novel features that result in a new snorkel system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art snorkel devices, either alone or in any combination thereof.




To attain this, the present invention generally comprises a breathing tube having an upper opening, a mouthpiece attached to a lower end of the breathing tube, a housing attached about an upper portion of the breathing tube, and a plurality of apertures within a lower portion of the housing. The upper opening of the breathing tube is positioned a finite distance above the highest of the apertures for creating a pressurized air pocket within the housing that prevents water level from rising above the upper opening thereby preventing water from entering the upper opening when the housing is fully submerged. The plurality of apertures within the lower portion allow the water to escape when the housing is elevated above the water surface and allow for air to immediately enter the housing and therefore the breathing tube thereby allowing the individual to freely breathe.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Turning now descriptively to the drawings, in which similar reference characters denote similar elements throughout the several views,

FIGS. 1 through 9

illustrate a snorkel system


10


, which comprises a breathing tube


20


having an upper opening


62


, a mouthpiece


30


attached to a lower end of the breathing tube


20


, a housing


70


attached about an upper portion


60


of the breathing tube


20


, and a plurality of apertures


72


within a lower portion


78


of the housing


70


. The upper opening


62


of the breathing tube


20


is positioned a finite distance above the highest of the apertures


72


for creating a pressurized air pocket within the housing


70


that prevents water level


14


from rising above the upper opening


62


thereby preventing water from entering the upper opening


62


when the housing


70


is fully submerged. The plurality of apertures


72


within the lower portion


78


allow the water to escape when the housing


70


is elevated above the water surface


12


and allow for air to immediately enter the housing


70


and therefore the breathing tube


20


thereby allowing the individual to freely breathe.




As shown in

FIGS. 1 through 4

of the drawings, the breathing tube


20


is comprised of a structure similar to a conventional breathing tube


20


having an upper portion


60


with an upper opening


62


and a mouthpiece


30


attached to a lower opening thereof. The breathing tube


20


preferably has a flexible portion


40


for allowing adjustment of the breathing tube


20


during operation. A clip member


50


may also be attached to the middle portion of the breathing tube


20


for attaching to a mask strap or similar structure.




As shown in

FIGS. 1 through 4

of the drawings, the housing


70


is attached about the upper portion


60


of the breathing tube


20


. The housing


70


may have various shapes and sizes as can be appreciated. The housing


70


is comprised of a body


76


having a lower portion


78


, a ceiling


74


, and an interior chamber. The housing


70


is comprised of a solid impermeable material such as but not limited to plastic or metal. The ceiling


74


is preferably a domed structure as shown in

FIGS. 1 through 4

of the drawings, however the ceiling


74


may be comprised of various other well known structures. The housing


70


may be comprised of an opaque, transparent or semi-transparent material such as but not limited to plastic.




As shown in

FIGS. 1 through 4

and


7


through


9


of the drawings, a flexible joint is preferably positioned within the breathing tube


20


below the housing


70


and upper portion


60


. The flexible joint allows the housing


70


and upper portion


60


to pivot about the flexible joint for allowing the housing


70


and upper portion


60


to be significantly aligned vertically within the water when submerged thereby preventing a portion of the water level


14


within the housing


70


from becoming higher than the upper opening


62


.




The lower portion


78


of the housing


70


may be tapered inwardly toward the breathing tube


20


. The lower portion


78


of the housing


70


preferably includes a plurality of apertures


72


within for allowing air to enter during normal snorkel operation as shown in

FIGS. 1

,


2


,


5


and


6


of the drawings. The apertures


72


may be comprised of various shapes, sizes, designs and structures as can be appreciated. The apertures


72


may be comprised of a random pattern or horizontal rows as illustrated in

FIGS. 1 through 4

of the drawings. The apertures


72


may surround the lower portion


78


of the housing


70


or the apertures


72


may be positioned in one or more specific locations upon the lower portion


78


.




As shown in

FIGS. 1 through 4

and


7


through


9


of the drawings, the upper apertures


72


are positioned a finite distance below the upper opening


62


of the breathing tube


20


. The distance of the upper apertures


72


from the upper opening


62


ranges depending upon the volume of space above the upper apertures


72


and the design of the housing


70


.




In use, the user may operate the snorkel system


10


as a conventional snorkel device allowing them to freely breathe while their head is submerged with the housing


70


above the water surface


12


as shown in

FIGS. 4 and 9

of the drawings. When the user dives deeper beneath the water surface


12


, the housing


70


becomes partially or fully submerged as shown in

FIGS. 3 and 8

of the drawings. Water is able to enter the interior of the housing


70


via the apertures


72


within the lower portion


78


of the housing


70


. As the water enters the housing


70


the water level


14


within the interior of the housing


70


rises above the upper apertures


72


a finite distance until the air pressure within the upper cavity of the housing


70


(i.e. space between water level


14


and ceiling


74


) equals the water pressure based upon the depth of the dive. If the user is positioned at an angle within the water, the flexible joint directly below the housing


70


allows the housing


70


to pivot into a substantially vertical position thereby maintaining the upper portion


60


of the breathing tube


20


substantially traverse to the water level


14


within the interior of the housing


70


. When the individual surfaces from the depths below the water surface


12


, the housing


70


becomes exposed above the water surface


12


as shown in

FIGS. 4 and 9

of the drawings. The water within the interior of the housing


70


is allowed to escape through the apertures


72


for allowing free breathing by the individual through the breathing tube


20


as further shown in

FIGS. 4 and 9

of the drawings. This process may be repeated numerous times by the individual as desired without water entering the breathing tube


20


.
