Abstract
Abstract A lightweight portable inflatable structure in the form of a baby's crib has a base portion and upstanding side walls integrally formed thereabout in communication therewith. Interconnecting webs formed by heat sealing the air impervious sheet material from which the inflatable structure is formed assist in controlling the size and shape of the inflatable structure and a separate rigid rectangular frame and supporting legs detachably supports the inflatable structure to prevent collapse in the event of loss of air pressure therefrom.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
185 words
An inflatable structure in the form of a baby's crib having a base portion and vertical side walls attached to the outermost edges thereof and in communication therewith, an opening in said inflatable structure and an air valve in said opening, said base portion having a plurality of longitudinally extending heat sealed seams therein terminating substantially inwardly of the ends and sides thereof so as to define a plurality of air passageways therebetween and communicating air passageways at the ends and sides thereof together with a peripheral flap therearound, a plurality of secondary heat sealed seams in said side walls terminating substantially inwardly of the upper and lower edges thereof so as to define continuously extending enlarged inflatable upper and lower rolled edge portions on said side walls and a plurality of inflatable interconnecting areas therebetween and flaps extending outwardly thereof, said flaps on said enlarged lower rolled edge portions of said side walls continuously joined to said peripheral flap around said base portion so that said vertical side walls are located inwardly of the outermost sections of said enlarged lower rolled edge portions thereof.
Claim 2
Dependent Claim
185 words
An inflatable structure in the form of a baby's crib having a base portion and vertical side walls attached to the outermost edges thereof and in communication therewith, an opening in said inflatable structure and an air valve in said opening, said base portion having a plurality of longitudinally extending heat sealed seams therein terminating substantially inwardly of the ends and sides thereof so as to define a plurality of air passageways therebetween and communicating air passageways at the ends and sides thereof together with a peripheral flap therearound, a plurality of secondary heat sealed seams in said side walls terminating substantially inwardly of the upper and lower edges thereof so as to define continuously extending enlarged inflatable upper and lower rolled edge portions on said side walls and a plurality of inflatable interconnecting areas therebetween and flaps extending outwardly thereof, said flaps on said enlarged lower rolled edge portions of said side walls continuously joined to said peripheral flap around said base portion so that said vertical side walls are located inwardly of the outermost sections of said enlarged lower rolled edge portions thereof.
Claim 3
Dependent Claim
37 words
The inflatable structure of claim 1 and wherein the structure is formed of a section of flexible sheet material doubled upon itself on a longitudinal fold line, and closed at its edges to form an airtight envelope.
Claim 4
Dependent Claim
43 words
The inflatable structure of claim 1 and wherein the structure is formed of a least two similarly shaped sections of flexible sheet material defining said side walls and said base portion and arranged for interconnection so as to be inflatable from said opening.
Claim 5
Dependent Claim
40 words
The inflatable structure of claim 1 and wherein the closed edges have extending flaps therealong with the flaps on the ends of the side walls attached to one another to form a right angular corner in the upstanding side walls.
Claim 6
Dependent Claim
57 words
The inflatable structure of claim 1 and wherein a plurality of fasteners are affixed to the upper rolled edge portions of the upstanding side walls and a lightweight rigid frame having supporting legs is positioned around said side walls and detachably affixed thereto by said fasteners so as to hold said sidewalls in upstanding position when deflated.
Claim 7
Dependent Claim
28 words
The inflatable structure of claim 1 and wherein the combined base portion is wider than the overall width of the structure thereabove defined by said upstanding side walls.
