Abstract

A self-inflatable air mattress (10) having a built-in bellows (44). A portion of the air mattress support (18) is manually moved up and down actuating the bellows (44) to introduce air into the mattress (10). The air inlet (30) is of large area and a substantial amount of air is introduced upon each manual actuation of the support (18). A valve (86) may be associated with the bellows (44) and air inlet (30) to selectively reverse the air flow so that the air mattress (44) can be quickly deflated, if desired.

Claims

AMENDED CLAIMS[received by the International Bureau on 17 January 1995 (17.01.95); original claims 1, 3 and 11 amended; original claim 12 deleted; remaining claims unchanged (3 pages)]

1. An air mattress assembly comprising: a first generally planar base portion movably connected to a second generally planar base portion; an inflatable air mattress having an opening therein communicating with the interior thereof; said first base portion having panel means with a flange plate mounted therein dividing said first base portion into an upper compartment and a lower compartment, said flange plate having at least a pair of spaced openings therethrough, one of said last-mentioned openings being aligned with the opening in said air mattress, said opening in said air mattress being in communication therewith; a pair of spaced plates movably mounted with respect to said flange plate and disposed in said lower compartment, each of said spaced plates having a first imperforate portion with a plurality of spaced openings therethrough and a second portion with a large opening therethrough, said spaced openings in one spaced plate being vertically aligned with one of the large opening through the other of said spaced plates and the large opening in said one spaced plate being vertically aligned with the spaced openings in the other of said spaced plates, said spaced openings in said one spaced plate and said vertically aligned large opening in said second spaced plate also being vertically aligned with one of said openings in said flange plate and said large opening in said one spaced plate and said vertically aligned spaced openings in said second spaced plate also being vertically aligned with the other of said openings in said flange plate; a resilient disk disposed between said spaced plates; plate moving means associated with said pair of spaced plates for selectively aligning, in a first position, said spaced openings in said one spaced plate with said large opening in said second spaced plate, and, in a second position, aligning said large opening in said one spaced plate with said spaced openings in said second spaced plate; and a bellows assembly mounted in said first base portion having an exhaust in fluid communication with both said opening leading into said air mattress and with the side of said second spaced plate coaxially aligned with the opening leading into said air mattress, said bellows assembly also having an air intake in fluid communication with the atmosphere whereby, moving said second base portion selectively away from and toward said first base portion draws air from the atmosphere through said air intake, into said bellows assembly and out said exhaust into said air mattress.

2. In the assembly of claim 1 wherein said plate moving means includes a handle extending through said flange plate and coupled to said pair of spaced plates and accessible in said upper compartment.

3. In the assembly of claim 2 wherein said handle is an elongated member extending transversely across said flange plate in said upper compartment.

4. In the assembly of claim 3 wherein said flange plate and said pair of spaced plates are circular.

5. In the assembly of claim l including handle means associated with said first and second base portions for carrying the same.

6. In the assembly of claim 1 including an air tube having an inlet at one end and an outlet in fluid communication with the interior of said bellows assembly at its other end.

7. In the assembly of claim 6 wherein said outlet is selectively closable.

8. In the assembly of claim 1 wherein said first and second base portions are movably connected by a hinge.

9. In the assembly of claim 1 wherein the area of said opening in said air mattress and the area of said large openings through said spaced plates is about 4 to 4-1/4 square inches.

10. In the assembly of claim 1 wherein said resilient disk is of rubber and flexes against said large opening in said one spaced plate and away from said spaced openings in said one spaced plate when said large opening in said one spaced plate is in fluid communication with the opening leading into said air mattress.

11. A quick inflatable apparatus comprising: an inflatable device having an opening leading therein for inflating the same; a platform having a first section secured to said device and a second section movably secured to said first section; and a bellows apparatus mounted between said first and second sections and actuable to deliver air into said device when said first section is moved with respect to said second section, said bellows apparatus having an opening in fluid communication with the opening leading into said inflatable device; and selectable air expelling means associated with said bellows apparatus and one of said sections for selectively expelling air out of said inflatable device, through said bellows apparatus and into the atmosphere when said first section is moved with respect to said second section.
