(Cl. 128145) This invention relates to a brathing apparatus and, more particularly, to an apparatus adapted for use by a swimmer to facilitate remaining submerged for extended periods of time.
Underwater swimming and exploration has become increasingly popular for the amateur swimmer and, in many geographical regions, is a highly developed sport possessed of intrigue, fascination, and highly educational virtues. The sport is one which can be enjoyed by young and old alike.
Various apparatus of this type have heretofore been proposed; however, because of design, they are possessed of one or more of the following shortcomings: (a) the apparatus is bulky and awkward to handle; (b) the apparatus seriously curtails the activities of the user thereof as to the depth and time of submersion permissible, and the extent of movement; the apparatus is of costly and complex construction and capable of use by one possessed of a high degree of swimming skill; and (d) the apparatus is possessed of dangerous potentialities and requires the exercise of a high degree of care when being used.
Thus, it is one of the objects of this invention to provide an apparatus which is not beset with the aforementioned shortcomings.
It is a further object of this invention to provide an apparatus which is readily portable, effective in operation, and inexpensive to produce.
Further and additional objects will appear from the description, accompanying drawings, and appended claims.
In accordance with one embodiment of this invention, a breathing apparatus is provided for use with a horizontally disposed buoyant apertured unit. The apparatus comprises a base adapted to be removably mounted on the unit. Mounted on the base, and extending upwardly therefrom, is an elongated inflexible first conduit having the upper free end thereof downwardly deflected toward the upper surface of the base and terminating a substantial distance therefrom.
lnsertable through an aperture in the buoyant unit and connected in fluid seal relation with the lower end of the first conduit is one end of an elongated flexible conduit. Both the first and second conduits are impervious to the fluid in which the unit is buoyant.
For a more complete understanding of this invention, reference should be made to the drawing, wherein:
FIGURE 1 is a view, on reduced scale, showing the improved apparatus in operation.
FIG. 2 is a fragmentary perspective view of the improved apparatus in assembled relation.
FIG. 3 is an enlarged bottom view of the improved apparatus in partially assembled relation with respect to a buoyant unit.
PK}. 4 is a sectional view, on reduced scale, taken along line 44 of FIG. 3.
FIG. 5 is a side elevational View of the improved apparatus in fully assembled relation.
Referring now to the drawing and, more particularly to FIG. 1, the improved breating apparatus is shown in use by a swimmer 11 submerged in a fluid, such as water, 12. The apparatus 10 is provided to facilitate underwater swimming or exploration.
Apparatus 10 comprises a base 13 which, in this instance, is formed at least in part of a pliable sheet material and is adapted to be removably mounted on a buoyant unit 14 which, in this instance, is in the form of an inflatable inner tube. By reason of the pliable character of base 13, the latter is adapted to readily conform to the contour of unit 14.
Mounted centrally on base 13, and extending upwardly therefrom, is an inflexible conduit or pipe 15, which has the upper free end thereof 16 deflected in a downward direction toward the upper surface of base 13. End 16 of pipe is spaced a substantial distance above the upper surface of base 13 and, in turn, the surface of the water 12 on which the unit 13 floats. Because of its downwardly deflected configuration, the possibility of liquid passing through the pipe is minimized, notwithstanding the fact that there is considerable turbulence of the water.
The pipe 15 terminates within a connector 17 which is aflixed, in this instance, to the central portion of base 13. The central portion of base 13 may, if desired, be of thicker material than the remainder of the base and thus prevent unbalancing of conduit 15 in the event the swimmer exerts a sudden jerk on the flexible conduit 18. The connector 17 has a downwardly extending portion 17a which is disposed within the central opening 14a of the unit 14. Portion 17a of the connector 17 is provided with internal threads and is adapted to accommodate an externally threaded end of an elongated flexible conduit or pipe 18. The length of pipe 18 is dependent upon the depth of the water in which the swimmer 11 desires to swim or otherwise maneuver.
To the lower end of pipe 18, in this instance, is connected a mouth and/or nose-piece 20 which is adapted to be properly positioned on the face of the swimmer and held in such positioned by suitable straps 21 or the like. Pipes 15 and 18 are preferably of a lightweight fluidimpervious material. Such piece 20 may, if desired, be omitted and the lower end of pipe 18 held directly in the mouth of the swimmer.
The marginal portion 13:: of the base 13, in this instance, is provided with a hem 22 in which is disposed a draw-cord 23. The cord 23, when drawn up tightly, causes the base 13 to snugly envelop the unit 14. Because of the pliable character of base 13 and the adjustability of draw-cord 23, the base is adapted to accommodate buoyant units 14, which vary widely in shape and size. When the base 13 is brought into snug engagement with unit 14, the central portion of base 13 might be raised up slightly, as seen in FIG. 5.
Thus, it will be seen that an improved apparatus has been provided which is extremely simple and inexpensive in construction, does not interfere with the movement of the arms and legs of the swimmer, may be utilized by young and old alike, and is of material aid to the swimmer when engaged in underwater activity.
While a particular embodiment of this invention is shown above, it will be understood, of course, that the invention is not to be limited thereto, since many modifications may be made and it is contemplated, therefore, by the appended claims, to cover any such modifications as fall within the true spirit and scope of this invention.
