Self inflatable air mattress, and sleeping bag with air pressure control

Claim 2

A self inflatable air mattress comprising a core of flexible and resilient cellular material of the open cell type allowing free passage of air therethrough, a substantially air tight flexible jacket enclosing said core, a tube communicating with the interior of said jacket from exteriorally thereof for flow of air into and from the cells of said core, and an openable and reclosable closure for said tube which in its closed condition with the cells filled with air prevents escape of air from said cells and maintains them filled with air to provide a resilient air cushion, and which when open and the mattress placed under compression allows escape of air from said cells and flattening of said mattress, said mattress having a mandrel about which it can be wound into a roll to compress the same and thus expel air from said tube and flatten the mattress when said closure is open, said mandrel when rolled with said tube closure closed expelling air from the core cells adjacent said mandrel while increasing pressure in the remaining cells above atmospheric pressure, and detachable connecting members on said mattress jacket to hold said mandrel in a substantially fixed adjusted position to maintain increased pressure with said tube closure closed.

Claim 3

The mattress of claim 1 wherein said detachable connecting members comprise flexible ties, one of which is attached at one end thereof to the top face of the jacket and another at one end thereof to the bottom face of said jacket, said ties holding the mandrel in said substantially fixed adjusted position when tied together.

Claim 4

The mattress of claim 2 wherein a pair of said flexible ties is provided adjacent each side edge of the mattress.

Claim 5

The mattress of claim 2 wherein the tie attached to said bottom face is of a length sufficient to extend over the mandrel end of the jacket and over the top face thereof.

Claim 6

A sleeping bag comprising a self inflatable air mattress having a core flexible and resilient cellular material of the open cell type allowing free passage of air therethrough, a substantially air tight flexible jacket enclosing said core and adhesively bonded thereto, a tube communicating with the interior of the jacket from exteriorally thereof for flow of air into and from the cells of said core, a manually removable cap for said tube whereby air can fill the core cells when the cap is removed and upon closing of said cap maintain the cells filled to provide a resilient air cushion, a cover overlying said jacket and attached thereto adjacent one end and opposite sides thereof, said cover having adjacent portions provided with an openable and reclosable closure to enable opening and closing of the cover, and said sleeping bag having adjacent an end thereof a mandrel about which the bag can be wound into a roll, said mandrel when being rolled with said tube closure closed expelling air from the core cells adjacent said mandrel while increasing pressure in the remaining cells above atmospheric pressure, and detachable connecting ties on said mattress jacket to hold said mandrel in a substantially fixed adjusted positIon to maintain increased pressure with said tube closure closed, one of said ties being attached to the top face of said mattress jacket at one end thereof, the attachment of said cover adjacent said one end of the jacket being to the bottom face of the jacket at a position ahead of said mandrel, and another of said ties being attached to the bottom face of the jacket between said mandrel and the location of attachment of the cover to said bottom face whereby the mandrel can be rolled up toward such location of attachment of said cover to said bottom face without interference from said cover.

Claim 7

A sleeping bag comprising a self inflatable air mattress having a core flexible and resilient cellular material of the open cell type allowing free passage of air therethrough, a substantially air tight flexible jacket enclosing said core and adhesively bonded thereto, a tube communicating with the interior of the jacket from exteriorally thereof for flow of air into and from the cells of said core, a manually removable cap for said tube whereby air can fill the core cells when the cap is removed and upon closing of said cap maintain the cells filled to provide a resilient air cushion, a cover overlying said jacket and attached thereto adjacent one end and opposite sides thereof, said cover having adjacent portions provided with an openable and reclosable closure to enable opening and closing of the cover, and said sleeping bag having adjacent an end thereof a mandrel about which the bag can be wound into a roll, said mandrel when being rolled with said tube closure closed expelling air from the core cells adjacent said mandrel while increasing pressure in the remaining cells above atmospheric pressure, and detachable connecting ties on said mattress jacket to hold said mandrel in a substantially fixed adjusted positIon to maintain increased pressure with said tube closure closed, one of said ties being attached to the top face of said mattress jacket at one end thereof, the attachment of said cover adjacent said one end of the jacket being to the bottom face of the jacket at a position ahead of said mandrel, and another of said ties being attached to the bottom face of the jacket between said mandrel and the location of attachment of the cover to said bottom face whereby the mandrel can be rolled up toward such location of attachment of said cover to said bottom face without interference from said cover.

Claim 8

The mattress of claim 5 wherein the tie attached to said bottom face of the jacket is of a length sufficient to extend over the mandrel end of the jacket and over the top face thereof.

Claim 9

The mattress of claim 5 wherein a pair of said flexible ties is provided adjacent each side edge of the mattress.
