Abstract
Abstract A method of manufacturing soft-sided luggage comprising the steps of forming in one piece an elongated plastic member having a U-shaped longitudinal cross section, transversely cutting from the member two frame elements of substantially identical, predetermined length, each frame element having a longitudinal U-shaped cross section including a base and two spaced, generally parallel legs, interconnecting the frame elements in opposed relationship by joining each opposed pair of legs with a one-piece resilient plastic wall element to form a generally rectangular hollow peripheral shell having two opposed open sides, and covering the shell with a flexible material including means for selectively obtaining access through at least one open side to the hollow interior of the shell.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
95 words
A frame for soft-sided luggage comprising: top and bottom plastic frame elements, each said frame element having substantially identical length and having a generally U-shaped longitudinal cross section including a base and spaced parallel legs, said frame elements being disposed in opposed relationship; and a resilient wall element joining each pair of opposed legs of said frame elements to define a generally rectangular hollow peripheral shell, said wall elements having a width generally equal to the width of said frame elements and being corrugated in a direction perpendicular to said width of said wall elements.
Claim 2
Dependent Claim
95 words
A frame for soft-sided luggage comprising: top and bottom plastic frame elements, each said frame element having substantially identical length and having a generally U-shaped longitudinal cross section including a base and spaced parallel legs, said frame elements being disposed in opposed relationship; and a resilient wall element joining each pair of opposed legs of said frame elements to define a generally rectangular hollow peripheral shell, said wall elements having a width generally equal to the width of said frame elements and being corrugated in a direction perpendicular to said width of said wall elements.
Claim 3
Dependent Claim
35 words
The frame of claim 1 wherein each said frame element includes a longitudinal planar portion and rounded transverse edges and wherein said wall elements and the planar portions of said frame elements are longitudinally coextensive.
Claim 4
Dependent Claim
17 words
The frame of claim 1 wherein each said frame element includes integrally-formed, longitudinally-extending, transversely-spaced, parallel reinforcing ribs.
Claim 5
Dependent Claim
43 words
The frame of claim 1 wherein said bottom frame element includes integrally-formed, longitudinally-spaced recesses open to the outside of said U-shaped bottom frame element, at least one said recess being disposed in the base of said bottom frame element proximate each leg thereof.
Claim 6
Dependent Claim
15 words
The frame of claim 4 wherein a wheel is operatively mounted in each said recess.
Claim 7
Dependent Claim
32 words
The frame of claim 3 wherein one longitudinal space between adjacent ribs in said top frame element is centrally located and has a length sufficient to permit attachment of a handle thereto.
