Abstract

An oversized air valve for use with inflatable devices typically in an above-the-ground swimming pool or an inflatable mattress is disclosed. In its most fundamental embodiment, the oversized air valve for use with inflatable devices includes a construction having an outer housing and a base flange connected to the outer housing for being secured to an inflatable device. A cylindrical passageway is formed through the outer housing for carrying pressurized air. A cap attached to the cylindrical passageway enables the air valve to be sealed against air leakage. Finally, a removable rigid member is insertable into the cylindrical passageway for preventing deformation to the air valve. The removable rigid member is force-fitted into the cylindrical passageway and is of a length sufficient to displace a back pressure flap hinged to the bottom of the cylindrical passageway. When partially inserted into the cylindrical passageway, the rigid member prevents deformation of the oversized air valve when the valves are tightly packed together. However, when fully inserted into the cylindrical passageway, the rigid member enables exhausting of the pressurized air through a displaced back pressure flap and the rigid member. In an alternative embodiment, an air sealing cap and a deflation insert are each attached to the cylindrical passageway by separate flexible leads.

Claims

1. An oversized air valve for use with inflatable devices comprising:

an outer housing;

a base flange connected to said outer housing for being secured to an inflatable device;

a cylindrical passageway formed through said outer housing for carrying pressurized air;

a cap attached to said cylindrical passageway for sealing against air leakage; and

a removable rigid member insertable into said cylindrical passageway for preventing deformation to said air valve, said rigid member comprising a solid cylindrical body and a plurality of fingers extending downward from a bottom of said solid cylindrical body.

2. The oversized air valve of claim 1 wherein said air valve is comprised of a flexible polymer material.

3. The oversized air valve of claim 1 wherein said air valve is comprised of flexible polyvinylchloride.

4. The oversized air valve of claim 1 wherein said air valve includes a 3/4" inside diameter dimension.

5. The oversized air valve of claim 1 wherein said removable rigid member is comprised of a rigid polymer.

6. The oversized air valve of claim 1 wherein said removable rigid member is comprised of polyproplene.

7. The oversized air valve of claim 1 wherein said removable rigid member is comprised of nylon.

8. The oversized air valve of claim 1 wherein said cap is attached to said cylindrical passageway with a flexible lead comprised of polyvinylchloride.

9. The oversized air valve of claim 1 wherein said cap attached to said cylindrical passageway further includes a finger tab.

10. An oversized air valve for use with inflatable devices comprising:

an outer housing;

a base flange connected to said outer housing for being secured to an inflatable device;

a cylindrical passageway formed through said outer housing for carrying pressurized air;

a back pressure flap hinged to a bottom of said cylindrical passageway; and

a removable rigid member insertable into said cylindrical passageway for displacing said back pressure flap and for exhausting said pressurized air from said inflatable device, said rigid member comprising a solid cylindrical body and a plurality of fingers extending downward from a bottom of said solid cylindrical body.

11. An oversized air valve for use with inflatable devices comprising:

an outer housing;

a base flange connected to said outer housing for being secured to an inflatable device;

a cylindrical passageway formed through said outer housing for carrying pressurized air;

a back pressure flap hinged to a bottom of said cylindrical passageway; and

a removable rigid member for inserting into said cylindrical passageway, said rigid member comprising

a solid cylindrical body;

an upper lip fused to said solid cylindrical body; and

a plurality of fingers extending downward from said solid cylindrical body.

12. An oversized air valve for use with inflatable devices comprising:

an outer housing;

a base flange connected to said outer housing for being secured to an inflatable device;

a cylindrical passageway formed through said outer housing for carrying pressurized air;

a back pressure flap hinged to a bottom of said cylindrical passageway;

a cap attached to said cylindrical passageway with a first flexible lead for sealing against air leakage; and

a rigid member attached to said cylindrical passageway with a second flexible lead and insertable into said cylindrical passageway for displacing said back pressure flap for injecting and exhausting said pressurized air into and from said inflatable device.

13. The oversized air valve of claim 12 wherein said rigid member further includes a cylindrical base.

14. The oversized air valve of claim 13 wherein said cylindrical base of said rigid member further includes a protuberance for displacing said back pressure flap.

15. The oversized air valve of claim 12 wherein said first flexible lead for attaching said cap to said cylindrical passageway is comprised of polyvinylchloride.

16. The oversized air valve of claim 12 wherein said second flexible lead for attaching said rigid member to said cylindrical passageway is comprised of polyvinylchloride.

17. The oversized air valve of claim 12 wherein said cap is insertable into said cylindrical passageway for preventing deformation of said air valve.
