Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
An article of soft luggage simulating an article of hard luggage, and comprising: at least one center section of soft luggage formed from a flexible and compliant material, and formable into a hollow rectangular cylinder having radiused corners; stiffening members arranged in spaced relationship and respectively positioned at opposite ends of each said radiused corner and extending substantially axially of said hollow cylinder; an interconnecting member extending axially of said center section at said radiused corner, said interconnecting member being formed from a stiff but compliant material and being conformable to said radiused corner; and, means securing said center section and said stiffening members and adjacent portions of said interconnecting member to each other in relative immoveable relationship solely in the vicinity of said stiffening members; whereby said interconnecting member is erectable to provide a stiffener for said corner, and is collapsible to permit flattening of said center section for storage.
Claim 2
Dependent Claim
151 words
An article of soft luggage simulating an article of hard luggage, and comprising: at least one center section of soft luggage formed from a flexible and compliant material, and formable into a hollow rectangular cylinder having radiused corners; stiffening members arranged in spaced relationship and respectively positioned at opposite ends of each said radiused corner and extending substantially axially of said hollow cylinder; an interconnecting member extending axially of said center section at said radiused corner, said interconnecting member being formed from a stiff but compliant material and being conformable to said radiused corner; and, means securing said center section and said stiffening members and adjacent portions of said interconnecting member to each other in relative immoveable relationship solely in the vicinity of said stiffening members; whereby said interconnecting member is erectable to provide a stiffener for said corner, and is collapsible to permit flattening of said center section for storage.
Claim 3
Dependent Claim
46 words
The article according to claim 1, in which said interconnecting member extends over said stiffening members and is secured directly to said center section in the vicinity of said stiffening members and peripherally of said stiffening members to immobilize said stiffening members within said interconnecting member.
Claim 4
Dependent Claim
82 words
The article according to claim 1, in which said stiffening members and said interconnecting member are located internally of said corner, and the length of the outer surface of said interconnecting member, when conformed to said corner, is greater than that length of said center section at said corner which extends between said stiffening members, whereby said corner of said center section is held under tension by said interconnecting member, and said interconnecting member is held under compression by said center section.
Claim 5
Dependent Claim

The article according to claim 1, in which said center section is provided with a slide fastener element at an axial end thereof for the attachment of another section of soft luggage to said one axial end of said center section.
Claim 6
Dependent Claim
44 words
The article according to claim 4, in which said center section and said another section are each provided with a peripheral stiffening reinforcement serving to support each said center section and said another section in the form of a rectangular member having radiused corners.
Claim 7
Dependent Claim
40 words
The article according to claim 1, in which said center section is provided with a slide fastener element at each axial end thereof for the attachment of other sections of soft luggage to opposite axial ends of said center section.
Claim 8
Dependent Claim
23 words
The article according to claim 1, in which said center section is provided with a peripheral stiffening reinforcement adjacent one axial end thereof.
Claim 9
Dependent Claim
