High performance ventilatory training mask incorporating multiple and adjustable air admittance valves for replicating various encountered altitude resistances

1. A wearable training mask providing variable inhalation resistance settings, comprising:

a depth defining and air impermeable body having an exterior surface and an interior surface exhibiting a perimeter extending seal such that said body is adapted to overlay a wearer's mouth and nose;

a plurality of air admittance valve subassemblies incorporated into locations along said body, each of said valve subassemblies having multiple resistance settings for affecting a degree of air flow into said mask in response to inhalation by the wearer;

said valve subassemblies each further having a stem support an air passageway configured base mounted through said body in communication with said exterior and interior surfaces;

a flexible diaphragm mounting to said stem within said base, a cap engaging upon an exterior side of said base and through which are defined a select number of air flow permitting apertures;

said diaphragm having a thin and substantially planar shape portion exhibiting an outline matching an inner facing perimeter of said base, a post exhibiting a channeled interior and extending from said planar shape portion and mounting over said supporting stem for arraying said planar portion within said base; and

straps extending from said body and having inter-engaging ends adapted for affixing about the wearers head.

2. The training mask as described in claim 1 , further comprising a plurality of interchangeable caps exhibiting different configurations of air flow permitting apertures.

3. The training mask as described in claim 2 , said interchangeable caps each further comprising an outer circumferential extending portion and an inner raised portion incorporating a selected number of apertures for establishing the inhalation resistance setting.

4. The training mask as described in claim 1 , farther comprising said diaphragm being reversibly mounted to said stem between a first position in which said planar shape extends radially at an elevated location within said base in an inhalation permitting configuration and a second position in which said planar shape overlays said passageway configured base in as substantially inhalation preventing configuration.

5. The training mask as described in claim 1 , said straps each farther comprising interior cutout configurations for seating around and behind the wearer's ears, along with opposite end disposed and inter-engageable hook and loop fasteners.

6. The training mask as described in claim 1 , said body further comprising a two layer construction including an outer fabric layer overlaying an inner rubberized layer integrating said perimeter extending seal.

7. The training mask as described in claim 1 , farther comprising first, second and third individual valve subassemblies.

8. A wearable training mask providing variable inhalation resistance settings, comprising:

a depth defining and air impermeable body having an exterior surface and an interior surface exhibiting a perimeter extending seal such that said body is adapted to overlay a wearer's mouth and nose;

at least one air admittance valve subassembly incorporated into at least one location along the body, the valve subassembly having a stem support an air passageway configured base mounted through said body in communication with said exterior and interior surfaces;

a flexible diaphragm mounting to said stem within said base, at least one cap interchangeably engaging upon an exterior side of said base and through which are defined a select number of air flow permitting apertures for establishing a selected resistance setting for affecting a degree of air flow into said mask in response to inhalation by the wearer;

said diaphragm having a thin and substantially planar shape portion exhibiting an outline matching an inner facing perimeter of said base, a post exhibiting a channeled interior and extending from said planar shape portion and mounting over said supporting stem for arraying said planar portion within said base; and

straps extending from said body and having inter-engaging ends adapted for affixing about the wearers head.

9. The training mask as described in claim 8 , further comprising said diaphragm being reversibly mounted to said stem between a first position in winch said planar shape extends radially at an elevated location within said base in an inhalation permitting configuration and a second position in which said planar shape overlays said passageway configured base in a substantially inhalation preventing configuration.

10. The training mask as described in claim 8 , said straps each further comprising interior cutout configurations for seating around and behind the wearer's ears, along with opposite end disposed and inter-engageable hook and loop fasteners.

11. The training mask as described in claim 8 , said body further comprising a two layer construction including an outer fabric layer overlaying an inner rubberized layer integrating said perimeter extending seal.

12. The training mask as described in claim 8 , further comprising first, second and third individual valve subassemblies.

13. The training mask as described in claim 8 , said interchangeable caps each further comprising an outer circumferential extending portion and an inner raised portion incorporating a selected number of apertures for establishing the inhalation resistance setting.

14. A wearable training mask providing variable inhalation resistance settings, comprising:

a depth defining and air impermeable body having a two layer construction including an outer fabric layer overlaying an inner rubberized layer integrating a perimeter extending seal such that said body is adapted to overlay a wearer's mouth and nose;

a plurality of air admittance valve subassemblies incorporated into locations along said body, each of said valve subassemblies having multiple resistance settings for affecting a degree of air flow into said mask in response to inhalation by the wearer;

said valve subassemblies each further having a stem support an air passageway configured base mounted through said body in communication with said exterior and interior surfaces;

a plurality of caps, each having a number of air apertures, a selected one of said caps affixing to each base of a selected valve subassembly, such that said caps are replaceably attached to establish variable total numbers of air flow permitting apertures; and

straps extending from said body and including interior cutout configurations adapted for seating around and behind the wearer's ears, opposite end disposed and inter-engageable hook and loop fasteners securing about the wearer's head.

15. The training mask as described in claim 14 , said valve subassemblies each further comprising a stem supporting and air passageway configured base mounted through said body in communication with said exterior and interior surfaces.

16. The training mask as described in claim 15 , further comprising a flexible diaphragm mounting to said stem within said base, a cap engaging upon an exterior side of said base and through which are defined a select number of air flow permitting apertures.

17. The training mask as described in claim 14 , each of said caps further comprising a perimeter extending rim, an underside of which resistively fitting over an exterior perimeter end surface associated with said each base of said valve subassemblies.
