Abstract

A mattress-like pad for human body support, comfort and recreational use in outdoor camping, in recreational vehicles, and in water craft. The pad, of rugged construction, includes a light-weight inner pad structure fabricated of a stacked arrangement of a multiplicity of like rectangularly configured layers of two-ply laminated sheet plastic material encapsulating between the plys of each layer a multiplicity of uniformly arranged, separated and sealed air bubbles. The air-bubble layers are maintained in their stacked arrangment by inter-layer fasteners located proximate only the corners of the stack so as to permit some shifting of the layers to accommodate human body support characteristics and permit tight rolling-up of the mattress-like pad for storage and carrying thereof. The inner pad structure is removably encased within a bag-like containment cover fabricated of polyvinylchloride-coated polyester woven open mesh fabric material. The head end of the cover includes an extending closure flap with fasteners whereby when the matress-like pad is rolled up upon itself from the foot end to the head end of the cover and over the closure flap, the fasteners of the flap interact with mating fasteners affixed to the underside of the cover to maintain the mattress-like pad in its rolled-up configuration.

Dependent claims

In a mattress-like pad for body support, comfort and recreational use on dry land, in land vehicles, and in water craft, a light-weight, air-buoyancy improvement of said pads comprising:

a) an inner pad structure fabricated on a stacked arrangement of two or more like rectangularly sized and configured layers of two-ply laminated sheet plastic material encapsulating between the plys of each layer a multiplicity of uniformly arranged and separated air bubbles, the plys of said layers being sealed together in the areas between said air bubbles, said stacked arrangement of said like layers being maintained by inter-layer fastening means proximate each corner thereof;
and
b) an outer bag-like containment cover having a closed foot end and a sealably open head end and of sufficient width and length for removably encasing said inner pad structure, said cover being fabricated from an elongated strip of polyvinylchloride-coated polyester woven open mesh fabric material including a first end portion of said material folded back over a central underside portion of said material with the mating edges of said portions sealed together whereby upon inside-out reversal of said edge-sealed portions said bag-like cover is formed with the sealed edges thereof positioned within said cover, and a second end portion of said cover material extending from said central portion at the head end of said cover and forming a closure flap, the central underside portion of said cover material and said closure flap bearing mating fastener means whereby upon rolling-up of said mattress-like pad upon itself from the foot end to the head end of said cover and over said flap said mating fastener means interact to maintain said pad in its rolled-up configuration.

In a mattress-like pad for human body support, comfort and recreational use in outdoor camping, in recreational vehicles, and in water craft, a rugged construction, light-weight, and air-buoyancy improvement thereof comprising:

a) an inner pad structure fabricated of a stacked arrangement of a multiplicity of like rectangularly configured layers of two-ply laminated sheet plastic material encapsulating between the plys of each layer a multiplicity of uniformly arranged and separated air bubbles, the plys of said layers being sealed together in the areas between said air bubbles, said like layers being maintained in said stacked arrangement by inter-layer fastening means proximate each corner thereof with said like layers being otherwise free to shift with respect to one-another to accommodate human body support characteristics and permit tight rolling-up of said mattress-like pads for the storage of carrying thereof;
and
b) an outer bag-like containment cover for said inner pad structure, said cover having a closed foot end and a sealably open head end and being of sufficient width and length for removably encasing said inner pad structure, said cover being fabricated from an elongated strip of polyvinylchloride-coated polyester woven open mesh fabric material and including a first end portion of said material folded back over a central underside portion of said material with the mating side edges of said first portion and of said central portion sealed together whereby upon inside-out reversal of said edge-sealed portions said bag-like cover is formed with the sealed edges thereof positioned within said cover, and a second end portion of said cover material extending from said central portion at the head end of said cover and forming a closure flap for said mattress-like pad, the central underside portion of said cover material and said closure flap bearing mating fastener means whereby upon rolling-up of said mattress-like pad upon itself from the foot end to the head end of said cover and over said closure flap said mating fastener means interact to maintain said mattress-like pad in its rolled-up configuration.
