DESCRIPTION OF THE PREFERRED EMBODIMENT

(21) A hydration respiration apparatus for providing clean air and water to a user according to a preferred embodiment of the present invention will now be described with reference to FIGS. 1 to 6c of the accompanying drawings. The hydration respiration apparatus 10 includes a respirator assembly 20 having a facemask 22, a hydration assembly 30 having a hydration tube 32 and hydration reservoir 50 and a backpack 60 configured to carry the hydration reservoir 50 in proximity to the hydration tube 32.

(22) The respirator assembly 20 includes a facemask 22 having a body portion 24 and a pair of opposed filter cartridges 48 coupled to opposed sides of the body portion 24. The body portion 24 of the facemask 22 has a front surface that defines an interior area therebeneath. The facemask 22 is configured to cover at least the nose and mouth of a user who wears the facemask 22 on his face. It is understood that the facemask 22 of the respirator assembly 20 may include face straps configured for attachment of the facemask 22 to a user's head (not shown). Each filter cartridge 26 is constructed and configured so as to intercept particulate impurities and to keep them from entering the interior area. The facemask 22 may include an exhale port 28 that defines an opening that enables a user wearing the facemask 22 to exhale and for the exhaled air to exit the interior area.

(23) The hydration assembly 30 includes a hydration tube 32 and a hydration reservoir 50 in fluid communication with the hydration tube 32. More particularly, the hydration tube 32 has a generally linear configuration and extends through a hole in the front surface of the facemask 22. The hydration tube 32 includes a proximal end 34 normally situated in the interior area of the facemask 22 and a distal end 36 displaced from or extending away from the front surface of the facemask 22. Preferably, the facemask 22 defines a hole through which the hydration tube 32 is inserted. In an embodiment, the hydration tube 32 is slidably movable in back and forth movement through the hole in the facemask 22 between a retracted configuration substantially outside the interior area (FIG. 4c) and a deployed configuration substantially inside the interior area (FIG. 5c). A bite valve 38 is positioned at the proximal end of the hydration tube 32, the bite valve being configured to dispense water from the supply hose into the hydration tube when the bite valve is bitten by a user.

(24) The hydration reservoir 50 is configured to contain a volume of a liquid, such as water, the hydration reservoir 50 having an inlet port 52 that receives a water transfer member, such as a hose, configured to refill the reservoir 50. The hydration reservoir 50, therefore, is refillable via the inlet port 52. The hydration reservoir 50 is displaced from the hydration tube 32 (such as being coupled to a backpack 60 as will be described later) but is in fluid communication therewith via a supply hose 54. The supply hose 54 is configured to keep said hydration tube 32 filled with liquid from the hydration reservoir 50.

(25) The proximal end 34 of the hydration tube 32 includes a bite valve 38 configured to selectively allow liquid, such as water, to pass through it when the hydration tube 32 is at the deployed configuration and a user bites down on the bite valve 38 with his teeth. The hydration tube 32 includes an outer portion 40 situated outside of the facemask 22 extending away from the hole and an inner portion 42 situated in the interior area extending inwardly from the hole. In an embodiment, the outer portion 40 includes a plurality of threads along its outer surface (FIGS. 4b and 5).

(26) The hydration assembly 30 includes an actuator operatively coupled to a distal end of the outer portion 40 of the hydration tube 32 and is configured to actuate movement of the hydration tube 32 in and out of the interior area of the facemask. In an embodiment, the actuator may be a knob 44 having a plurality of threads complementary to and engaged with the threads along the outer portion 40 of the hydration tube 32 such that a rotation of the knob 44 causes the hydration tube 32 to be moved between a deployed configuration in which the outer portion 40 (FIG. 5c) is outside the inner portion 42 and a retracted configuration in which the outer portion 40 is substantially outside of the interior area (FIG. 4c) when twisted in clockwise and counterclockwise directions, respectively. The outer portion 40 is coupled to the inner portion 42 so as to push the inner portion 42 further into the interior area or to pull the inner portion 42 out of the interior area when the knob 44 is twisted. At the deployed configuration, the bite valve 38 is positioned proximate a user's mouth when the facemask 22 is strapped to the user's head.

(27) In another embodiment, the actuator may be a linear actuator 45 that includes a shaft having a generally linear configuration slidably coupled to the front wall of said facemask 22 and aligned to move through the hole in the facemask 22. The shaft 46 includes an inner end operatively coupled to a distal end of the hydration tube 32 and is configured to urge the hydration tube 32 between the deployed and retracted configurations described above. In use, a user may simply push the linear actuator 45 (i.e. the shaft) to move the bite valve 38 into the mouth of the user and, conversely, pull on the linear actuator 45 to retract the bite valve away from the user's mouth.

(28) In either embodiment described above, the knob 44 actuator or the linear actuator 45 include means for enhancing the grip of a user to turn or push it, respectively. For instance, each actuator may include a plurality of ridges 48, surface dimples, or other elements that enhance the dexterity of a user gripping the actuator to then move the hydration tube 32 between retracted and deployed positions.

(29) In another aspect, the hydration respiration apparatus 10 includes a backpack 60 having a back portion 62 and a pair of front straps 64 coupled to and extending from the back portion 62. The front straps 64 are spaced apart from one another and are configured to be worn over the shoulders of a user in the manner of a traditional backpack. One or more fasteners 66, such as quick connect or snap fit buckles, are coupled to the back portion 62 that are selectively and releasably coupled to the hydration reservoir 50. In other words, the hydration reservoir 50 may be worn on the back of a user when coupled to the back portion 62 and the front straps 64 of the backpack 60 are worn on a user's shoulders.

(30) The backpack 60 is characterized by additional features. More particularly, the back portion 62 may include at least one reflective strip 63 that is configured to reflect light so that a user wearing the backpack 60 is more visible. This is a safety feature that is even more important if a worker wearing the backpack 60 in an industrial area where forklifts, trucks, or other machinery is present.

(31) Further, a safety vest 68 may be coupled to a front surface of the front straps 64 of the backpack 60 (FIG. 1a), the safety vest 68 being constructed of a mesh or thin plastic material so as to shield the front of a user from dirt, paint overspray, or other undesirable elements he may encounter while working. The safety vest 68 may also include a reflective strip 63. In an embodiment, safety vest 68 may be removably attached to the front straps 64 with corresponding hook and loop fastener combinations or similar fasteners.

(32) In use, the hydration reservoir 50 may be filled with drinking water via the inlet port 52 and the hydration reservoir is attached to the back portion 62 of the backpack 60 via the fasteners 66. The front straps 64 may be slipped over a user's shoulders so that the backpack 60 may be carried on a user's penetration, The facemask 22 of the respiration assembly 20 may be strapped to a user's face. Then, when the user desires a drink of water, he may move the hydration tube 32 toward the deployed configuration as described above and bite down on the bite valve 38 such that water is dispensed into the user's mouth. When finished, the user may reverse movement of the hydration tube to the retracted configuration. Accordingly, the user is able to maintain hydration without ever removing the entire facemask 22 from his head.

(33) It is understood that while certain forms of this invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
