Abstract
Abstract The present invention provides an imitation lighter-than-air craft envelope assembly for use in conjunction with an attached imitation gondola. The assembly comprises an inflatable gas bag capable of containing a gas, and an imitation envelope which surrounds the gas bag. The imitation envelope simulates an actual lighter-than-air craft envelope when the gas bag is inflated within the envelope.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
131 words
A method of assembling an imitation lighter-than-air apparatus, comprising the steps of: (a) combining an exterior imitation envelope and a skirt, said envelope defining an interior cavity, and said skirt extending downwardly from said envelope and defining a longitudinal passage providing access to said interior cavity of said envelope; (b) inserting an inflatable gas bag while in a substantially deflated state into said cavity through said longitudinal passage of said skirt, said gas bag having a selectively sealable mouth and capable of containing a gas; (c) inflating said gas bag by introducing a gas through said mouth until said gas bag substantially fills said cavity defined by said imitation envelope; and (d) sealing said mouth of said gas bag, such that said apparatus imitates an actual hot-air balloon envelope and skirt.
Claim 2
Independent Claim
131 words
A method of assembling an imitation lighter-than-air apparatus, comprising the steps of: (a) combining an exterior imitation envelope and a skirt, said envelope defining an interior cavity, and said skirt extending downwardly from said envelope and defining a longitudinal passage providing access to said interior cavity of said envelope; (b) inserting an inflatable gas bag while in a substantially deflated state into said cavity through said longitudinal passage of said skirt, said gas bag having a selectively sealable mouth and capable of containing a gas; (c) inflating said gas bag by introducing a gas through said mouth until said gas bag substantially fills said cavity defined by said imitation envelope; and (d) sealing said mouth of said gas bag, such that said apparatus imitates an actual hot-air balloon envelope and skirt.
Claim 3
Dependent Claim
40 words
The method of assembly as claimed in claim 1, wherein said gas bag is inflated by an amount of lighter-than-air gas sufficient to lift said gas bag, said envelope, and said skirt relative to the atmosphere surrounding said gas bag.
Claim 4
Dependent Claim
31 words
The method of assembly as claimed in claim 2, wherein in step "c", said gas bag is inflated such that said gas bag substantially fills said interior cavity of said envelope.
Claim 5
Dependent Claim
37 words
The method of assembly as claimed in claim 3, wherein in step "c", said gas bag is inflated such that said mouth of said gas bag is accessible through said passage after said gas bag is inflated.
Claim 6
Dependent Claim
37 words
The method of assembly as claimed in claim 2, wherein in step "c", said gas bag is inflated such that said mouth of said gas bag is accessible through said passage after said gas bag is inflated.
Claim 7
Dependent Claim
31 words
The method of assembly as claimed in claim 1, wherein in step "c", said gas bag is inflated such that said gas bag substantially fills said interior cavity of said envelope.
Claim 8
Dependent Claim
37 words
The method of assembly as claimed in claim 6, wherein in step "c", said gas bag is inflated such that said mouth of said gas bag is accessible through said passage after said gas bag is inflated.
Claim 9
Dependent Claim
37 words
The method of assembly as claimed in claim 1, wherein in step "c", said gas bag is inflated such that said mouth of said gas bag is accessible through said passage after said gas bag is inflated.
