Abstract

An air support article of air inflatable furniture comprises an air inflation device. The air inflation device provides an openable and closable opening into the sack that forms the majority of the article. The air inflation device comprises at least one pliable flap attached to the sack. The flap acts as a partial check valve that allows the article to be inflated simply by rapidly opening and closing the opening.

First claim

What is claimed is:

1 . An air support article of air inflatable furniture comprising:
a sack being formed of a pliable material having a hollow interior, the sack being configured and adapted to be adjusted between an inflated configuration and a deflated configuration, the sack being configured to at least partially support a human above a surface when the sack is in the inflated configuration, the sack being configured to be folded compactly upon itself when in the deflated configuration; and an air inflation device, the air inflation providing an opening into the hollow interior of the sack, the air inflation device comprising first and second resiliently flexible elongate members, the resiliently flexible elongate members each having a first axial end and a second axial end, the resiliently flexible elongate member second end being opposite the resiliently flexible elongate member first end, the first ends of the resiliently flexible elongate members being operatively connected to each other, the second ends of the resiliently flexible elongate members being operatively connected to each other, the resiliently flexible elongate members being configured and adapted to be moved in opposite directions from each other in a manner to form an opening into the sack and place the opening in an open configuration, the resiliently flexible elongate members also being configured and adapted to be moved adjacent to each to close the opening into the sack and place the opening in a closed configuration, the air inflation device having at least one pliable flap, the at least one pliable flap having opposite leading and trailing edges, the leading edge of the at least one primary pliable flap being operatively attached at least adjacent to the first resiliently flexible elongate member, the trailing end of the at least one primary pliable flap being unattached to the sack and free to move within an interior of the sack, the air inflation device being configured such that movement of the resiliently flexible elongate members from the closed configuration of the opening to the open configuration of the opening causes the at least one primary pliable flap to move into the interior of the sack so as to (i) at least partially block the opening for preventing any air within the interior of the sack from exiting the sack through the opening, and (ii) allow air outside the sack to enter into the interior sack through the opening past a trailing edge of the at least one primary pliable flap.

2 . The air support article of air inflatable furniture of claim 1 wherein the at least one primary pliable flap of the air inflation device comprises a first primary pliable flap, the air inflation device further comprises a second primary pliable flap, the second primary pliable flap having opposite leading and trailing edges, the leading edge of the second primary pliable flap being operatively attached at least adjacent to the second resiliently flexible elongate member, the trailing end of the second flap being unattached to the sack and free to move within the sack, the air inflation device being configured such that movement of the resiliently flexible elongate members from the closed configuration of the opening to the open configuration of the opening causes the second primary pliable flap to move into the interior of the sack so as to (i) at least partially block the opening for preventing any air within the interior of the sack from exiting the sack through the opening, and (ii) allow air outside the sack to enter into the interior sack through the opening past a trailing edge of the second primary pliable flap.

3 . The air support article of air inflatable furniture of claim 2 wherein the air inflation device further comprises pliable first and second secondary flaps, the first and second secondary flaps being arranged opposite each other across the opening such that the first and second secondary flaps and the first and second primary pliable flaps together form a sleeve in the interior of the sack, the first and second secondary flaps being more pliable than the first and second primary flaps so as not to interfere with movement of the first and second primary flaps at least partially toward each other.

4 . The air support article of air inflatable furniture of claim 3 wherein the first and second secondary flaps are configured to limit the extent to which the first and second primary flaps move away from each other when the resiliently flexible elongate members are moved from the closed configuration of the opening to the open configuration of the opening.

5 . The air support article of air inflatable furniture of claim 1 wherein when the resiliently flexible elongate members are movable adjacent to each other in a closed configuration of the opening, the elongate members form a curved configuration with no external force applied to the air support article.

6 . The air support article of air inflatable furniture of claim 1 wherein the resiliently flexible elongate members are subjected to a compressive force along their length by the sack such that the resiliently flexible elongate members form a curved configuration with no external force applied to the air support article.

7 . The air support article of air inflatable furniture of claim 1 wherein the air inflation device comprises axial ends corresponding to the axial ends of the resiliently flexible elongate members and the axial ends of the air inflation device are releaseably connectable to each other in a manner such that when the opening is in the closed configuration, the air inflation device can be formed in a closed loop with the resiliently flexible elongate members adjacent to each other in the loop.

8 . The air support article of air inflatable furniture of claim 7 wherein the sack includes a portion adjacent to the air inflation device that is configured to be wound about the resiliently flexible elongate members of the air inflation device when the sack is partially filled with air and the opening is in the closed configuration with the axial ends of the air inflation device unconnected to each other such that air pressure within the sack can be increased prior to releasably connecting the axial ends of the air inflation device to form the loop.

9 . An air support article of air inflatable furniture comprising:
a sack being formed of a pliable material having a hollow interior, the sack being configured and adapted to be adjusted between an inflated configuration and a deflated configuration, the sack being configured to at least partially support a human above a surface when the sack is in the inflated configuration, the sack being configured to be folded compactly upon itself when in the deflated configuration; and an air inflation device providing an opening into an interior of the sack, the air inflation device comprising resiliently flexible elongate members defining the opening, each of the members having a first axial end and an opposite second axial end, the first ends of the resiliently flexible elongate members being operatively connected to each other, the second ends of the resiliently flexible elongate members being operatively connected to each other, the first and second resilient flexible elongate members being configured and adapted to be moved in opposite directions from each other in a manner to move the opening between an open configuration and a closed configuration, the air inflation device having a sleeve with a leading edge of the sleeve being operatively attached at least adjacent to the first and second resiliently flexible elongate members, the trailing end of the sleeve being unattached to the sack and free to move within the interior of the sack, the air inflati
