Abstract
Abstract An article of luggage which includes a luggage case having a peripheral side wall which is made of a flexible material. In order to impart some degree of rigidity to this flexible side wall, a frame structure is situated in the interior of the luggage case and extends along the inner surface of the side wall thereof. This frame structure has at each of a plurality of regions thereof a pair of frame portions which are substantially rigid and which terminate in free ends which are spaced from and directed toward each other. This frame structure also includes at each of the above regions thereof a spring construction which is operatively connected with the frame portions for acting on the latter to urge them apart from each other so as to tend to increase the distance between the free ends thereof. Thus, the substantially rigid frame portions are pressed by the spring means against the inner surface of the side wall of the luggage casing to impart a certain degree of rigidity to the side wall. At the same time, because of the presence of this spring construction it is possible for the luggage casing to resiliently yield when encountering impacts, crushing forces, or the like, with the spring construction returning the parts to their original condition when these impacts, crushing forces, and the like no longer act on the article of luggage.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
142 words
In an article of luggage, a luggage case having a peripheral side wall made of a flexible sheet material and having an inner surface directed toward the interior of the luggage case, and frame means engaging said side wall at said inner surface thereof and extending along said side wall for imparting a degree of rigidity thereto, said frame means including at each of a plurality of regions thereof a pair of substantially rigid frame portions respectively terminating in free ends which are spaced from and directed toward each other, and spring means operatively connected with said frame portions for urging them apart from each other to tend to increase the distance between said free ends thereof so that the article of luggage is capable of resiliently yielding at said side wall thereof in response to impacts, crushing forces, and the like.
Claim 2
Dependent Claim
142 words
In an article of luggage, a luggage case having a peripheral side wall made of a flexible sheet material and having an inner surface directed toward the interior of the luggage case, and frame means engaging said side wall at said inner surface thereof and extending along said side wall for imparting a degree of rigidity thereto, said frame means including at each of a plurality of regions thereof a pair of substantially rigid frame portions respectively terminating in free ends which are spaced from and directed toward each other, and spring means operatively connected with said frame portions for urging them apart from each other to tend to increase the distance between said free ends thereof so that the article of luggage is capable of resiliently yielding at said side wall thereof in response to impacts, crushing forces, and the like.
Claim 3
Dependent Claim
66 words
The combination of claim 1 and wherein said portions of said frame means at each of said regions thereof normally extend along a given line bridging the space between said free ends of said frame portions, and said spring means acting on said frame portions not only to urge the latter apart from each other but also to yieldably maintain said frame portions along said line.
Claim 4
Dependent Claim
49 words
The combination of claim 2 and wherein said spring means acts on said frame portions at each region of said frame means to urge said frame portions apart from each other while also yieldably and resiliently opposing twisting of one of said frame portions with respect to the other.
Claim 5
Dependent Claim
83 words
The combination of claim 3 and wherein said spring means at each of said regions of said frame means includes a pair of legs which when said spring means is in an unstressed condition are substantially coplanar and situated at a given distance from each other greater than the distance between said free ends of said frame portions, and said legs of said spring means being situated at least in part between and in engagement with said free ends of said frame portions.
Claim 6
Dependent Claim
25 words
The combination of claim 4 and wherein said legs of said spring means extend transversely with respect to said frame portions laterally beyond the latter.
Claim 7
Dependent Claim
27 words
The combination of claim 5 and wherein said spring means has a coil portion situated laterally beyond said frame portions and forming an extension of said legs.
Claim 8
Dependent Claim
53 words
The combination of claim 5 and wherein said frame portions respectively have hollow interiors which respectively terminate in openings at said free ends of said frame portions, and said legs of said spring means respectively having elongated extensions projecting respectively into said hollow interiors of said frame portions through said open ends thereof.
Claim 9
Dependent Claim
24 words
The combination of claim 7 and wherein each of said extensions at each leg of said spring means is of a substantially looped configuration.
Claim 10
Dependent Claim
32 words
The combination of claim 8 and wherein each frame portion has at its hollow interior an inner surface formed with a pair of opposed grooves respectively receiving opposed regions of each extension.
Claim 11
Dependent Claim
142 words
The combination of claim 1 and wherein said side wall has curved corner sections and elongated straight sections extending between and forming continuations of said curved corner sections, and said side wall having a pair of opposed edge portions each extending peripherally along said side wall, said regions of said frame means including at least a pair of regions situated adjacent said edge portions of said side wall substantially at a location where a straight section thereof joins a curved corner section thereof, and said frame means including at each of said pair of regions a straight frame portion extending along said straight section and a curved frame portion extending along said curved section with said straight and curved portions at each region of said frame means having said free ends which are urged apart from each other by said spring means.
Claim 12
Dependent Claim
71 words
The combination of claim 10 and wherein said frame means includes a plurality of said frame portions extending along said inner surface of said side wall adjacent said edge portions thereof, and a plurality of spacer plates extending between and interconnecting those frame portions which extend along one of said edge portions of said side wall to those frame portions which extend along the other edge portion of said side wall.
Claim 13
Dependent Claim
77 words
The combination of claim 10 and wherein each spring means includes a pair of legs extending between free ends of said pair of frame portions at each region of said frame means and engaging said free ends to urge them apart from each other, a pair of said spring means at said pair of regions being opposed to each other and extending laterally from the free ends of said frame portions at each region toward each other.
