Abstract
Abstract A collapsible cradle or platform for retaining an article of furniture above floor level in an inflated condition. The cradle includes a pair of base or leg members disposed parallel to each other and a pair of side support members joined to the base members to lie normal to said base members. Support straps extend between side members. The side members are bent inwardly toward each other in relaxed position for receipt of the lower surface of the uninflated article of furniture. As the article is inflated, the side members are tensed about the article''s lower surface and squeezed against the article to retain the same on the cradle.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
182 words
A platform for retaining an inflatable article of furniture above floor level comprising, a pair of resilient base members each having an elongate portion and an upstanding short portion at either end thereof, a pair of side support members each having a support bar with opposite ends disposed transverse to said support bar, said opposite ends being adapted for removable connection respectively to the short portions of opposite base members such that said side support members are disposed above and normal to said base members, and a plurality of support straps extending between said side support members, said side support members being movable between a first relaxed position and a second tensed position, whereby when said article of furniture is inflated in place upon said support straps, the inflated article will press against the side support members and assert a force thereagainst to move the same apart from said first position to said second position such that said side support members will resiliently engage opposite lower side surfaces of the inflated article to maintain the same in squeezed condition on said platform.
Claim 2
Dependent Claim
182 words
A platform for retaining an inflatable article of furniture above floor level comprising, a pair of resilient base members each having an elongate portion and an upstanding short portion at either end thereof, a pair of side support members each having a support bar with opposite ends disposed transverse to said support bar, said opposite ends being adapted for removable connection respectively to the short portions of opposite base members such that said side support members are disposed above and normal to said base members, and a plurality of support straps extending between said side support members, said side support members being movable between a first relaxed position and a second tensed position, whereby when said article of furniture is inflated in place upon said support straps, the inflated article will press against the side support members and assert a force thereagainst to move the same apart from said first position to said second position such that said side support members will resiliently engage opposite lower side surfaces of the inflated article to maintain the same in squeezed condition on said platform.
Claim 3
Dependent Claim
69 words
A platform as claimed in claim 1 further comprising connector means for joining together said opposite ends with said short portions, said means each having a first and second portion, said first portion being adapted to receive one of said opposite ends and said second portion being adapted to receive one of said short portions, each said opposite end and said second portion juxtaposed opposite sides of said means.
Claim 4
Dependent Claim
42 words
A platform as claimed in claim 1 in which the end of one of said pair of opposite ends and short portion is of reduced cross-sectional dimension to be received within the other of said pair of opposite eNds and short portions.
Claim 5
Dependent Claim
22 words
A platform as claimed in claim 1 in which said support straps are flexible and slacked prior to inflation of said article.
Claim 6
Dependent Claim
30 words
A platform as claimed in claim 1 in which said short portions are disposed at an acute angle to said elongate portion at least prior to inflation of said article.
Claim 7
Dependent Claim
39 words
A platform as claimed in claim 2 in which there is a reduced dimension connecting portion between said first and second portions and said opposite end and said second portion are disposed on opposite sides of said connecting portion.

17 words
A platform as claimed in claim 1 in which said platform is formed of tubular metal stock.
Claim 9
Dependent Claim
209 words
The combination of an inflatable article of furniture and a platform for retaining the article above floor level, said platform comprising, a pair of resilient base members each having an elongate portion and an upstanding short portion at either end thereof, a pair of side support members each having a support bar with opposite ends disposed transverse to said support bar, said opposite ends being adapted for removable connection respectively to the short portions of opposite base members such that said side support members are disposed above and normal to said base members, and a plurality of support straps extending between said side support members, an inflatable seating furniture article having a seating chamber to be supported on said straps between said side support members, said side support being movable between a first relaxed position and a second tensed position, whereby when said article of furniture is inflated in place upon said support straps, the seating chamber will press against the side support members and assert a force thereagainst to move the same apart from said first position to said second position such that said side support members will resiliently engage opposite lower side surfaces of the inflated article to maintain the same in squeezed condition on said platform.
Claim 10
Dependent Claim
209 words
The combination of an inflatable article of furniture and a platform for retaining the article above floor level, said platform comprising, a pair of resilient base members each having an elongate portion and an upstanding short portion at either end thereof, a pair of side support members each having a support bar with opposite ends disposed transverse to said support bar, said opposite ends being adapted for removable connection respectively to the short portions of opposite base members such that said side support members are disposed above and normal to said base members, and a plurality of support straps extending between said side support members, an inflatable seating furniture article having a seating chamber to be supported on said straps between said side support members, said side support being movable between a first relaxed position and a second tensed position, whereby when said article of furniture is inflated in place upon said support straps, the seating chamber will press against the side support members and assert a force thereagainst to move the same apart from said first position to said second position such that said side support members will resiliently engage opposite lower side surfaces of the inflated article to maintain the same in squeezed condition on said platform.
Claim 11
Dependent Claim
31 words
