LUGGAGE CASE END WALL. CONSTRUCTION Filed Sept. 12, 1961 INVENTON HARVEY L.oNE|L ATTORNEYS.

United states .arent 3,071,220 LUGGAGE CASE END WALL CONSTRUCTIIN Harvey L. Neil, Lebanon, Tenn., assigner to Hartmann Luggage Company, Lebanon, Tenn., a corporation of u Delaware Filed Sept. 12, 1961, Ser. No. 137,648 3 Claims. ('Cl. 19d- 50) This invention relates to improvements in luggage case end wall construction, and more particularly to the end wall construction for a soft-sided luggage case.

Soft-sided luggage cases and traveling bags are popular, but heretofore it has been dicult to provide a satisfactory type of soft-sided luggage case which would retain its form when in an unpacked or semi-packed condition and which would not be undesirably squashed, deformed and distorted when subjected to rough handling and during transportation.

The l. P. Ritter, Jr., Patent No. 2,746,581 is a typical example of the general type of soft-sided luggage cases to which the present invention pertains, but in said structure the reinforcing, rigid end walls cannot flex or distort during rough handling, which is a particularly acute problem in respect to luggage used in air travel, wherein the piece of luggage may be dropped or banged at any angle, which, in the case of a luggage piece having rigid end walls,'n1ay often subject said end walls to such forces as will cause breakage thereof.

With the above in mind, it is a primary object of the present invention to provide a soft-sided, rigid end wall type of luggage case wherein said rigid end walls have their top and bottom margins, which adjoin other wall portions of the case, tipped with resilient sheet material which will permit resilient deflection of said end walls in any direction, should the luggage case be subjected to blows and pressure, whereby the rigid end walls are relieved of such deiiecting forces or blows as would cause damage thereto.

A further object of the invention is to provide, in a luggage case of the character described, an improved deectable end wall construction, which, while reinforcing the ends of the case to preserve form and stability, will prevent collapse of the case and damage to the end walls when the same are subjected to undue pressures, such construction in no wise adding to the weight or detracting from the appearance of the case.

A further object of the invention is to provide an end wall construction for a soft-sided luggage case wherein said end walls may be removed from the case if desired.

A further object of the invention is to provide, in a luggage case, a wall construction wherein the front and rear walls of the case are soft but the end walls are reinforced or stiffened by wood panels tipped with resilient sheet material to relieve the case and rigid end walls from damage resulting from undue bumps, strains and stresses.

A further object of the invention is to provide a reinforced, soft-sided luggage case construction wherein the case has an attractive and unique appearance with the interior being accessible through a flap-controlled access opening, the case being simple and light in construction, strong and durable and able to withstand rough handling, and, furthermore, well adapted for the purposes described.

With the above and other objects in view, the invention consists of the improved end wall construction for a soft-sided luggage ease, and its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing, in lwhich the same reference characters designate the same parts in all of the views:

FIG. 1 is a front and end perspective view of a softsided luggage case embodying the improved end wall construction, part being broken away to show structural features;

FIG. 2 is an enlarged vertical sectional view taken approximately along line 2-2 of FIG. l, with portions broken away and in section;

FIG. 3 is a fragmentary horizontal sectional view taken on line 3 3 of FIG. 2;

FIG. 4 is an enlarged face view of a removable end wall, with a portion of one of the resilient marginal tips broken away; and

FIG. 5 is an enlarged fragmentary sectional view taken on line 5 5 of FIG. 4.

The improved soft-sided luggage case is shown in its closed condition in FIG. l of the drawing, and it is to be observed from FIG. 2 that a continuous sheet of any desired flexible fabric covering material, such as canvas, plastic, cloth, leather, or the like, is arranged in foursided form to provide the front and

rear sides

10 and 11 of the case, as Well as inner layers 12 and 1.3 of the top and bottom, respectively. The latter include

rigid veneer panels

14 and 15, which are suitably covered by exterior layers of leather, plastic, or the like, designated 16 and 17. The reinforced top member 12--14-16 carries a handle 18 and the reinforced bottom 13-15-17 carries bottom cleats 19.

The flexible covering material forming all of the walls previously mentioned at its end edges has stitched thereto resilient end welts 20, which are U-shaped in cross-section and which follow the peripheries of the ends and which also have stitched thereinto the flanged extremities of -iiexible end covering sheets 21.

To reinforce and give rigidity and form to these otherwise flexible ends, there is provided, pursuant to the present invention, for each end, an interiorly disposed end wall panel, designated generally by the numeral 22, and one of which is shown in detail in FIG. 4. The major portion 23 of each panel is preferably formed of some rigid material as wood veneer and the rigid panel portion 33 is of slightly less length than the vertical distance between the top and bottom portions of the welt 2@ surrounding a case end. The particular feature of the present invention resides in the inclusion of resilient tips or caps 24 to the top and bottom margins of the panel portion 23. As is best shown in FIG. 5, each tip or cap 24 is in fact bi-layered and portions of the layers receive therebetween end marginal portions of the panel 23, the layers of the tips being secured to the panel portions 23 by lines of stitching 25 or other suitable securing means. The -bi-layers of the tips 24 extend beyond the respective margins of the panel portions 23 and are secured together, as at 26. The layers forming each tip 24 are formed of a rubberized synthetic fibrous sheet material having resiliency and a suitable material for this purpose is that known under the trademark PellorL Side edge portions of the tips 24 are rounded so as to conform to the peripheries of the case ends as outlined by the continuous end welts 2t). As the sheet material forming said tips or caps projects beyond the margins of the panel portions 23 to which the tips are applied, it will be evident that said projecting tip portions may flex, bend or deforrn in any direction and possess resiliency.

The interior of the improved luggage case may be finished or lined in any desired manner and at the ends of the case there are interior fabric pockets designated by the

numerals

27 and 27 in FIGS. 2 and 3. The flap 27 overlaps the margin of the pocket portion 27 and is normally secured thereto by snap fasteners 23 which, when released, permit the closure flap 27 to be folded back to expose the pocket inwardly of the portion 27. Within these pockets, at each end of the case, the end walls 22 are normally removably disposed with their resilient tips in wedging or relatively tight contact with 'L the adjacent portions of the top and bottom walls of the case and with their side margins engaging the front and rear walls of the case. Obviously the end walls 22 may be removed from their retaining pockets 217-27 for repairs or replacement and the removal of the end walls will also permit the case to be flattened or compacted for storage, when not in use.

From FIG. 1 it Will be observed that the `front wall 1t? of the case, extending from the forward margin of the top 16 downwardly, is provided with a U-shaped opening adapted to be closed by a lined flexible cover Hap 29 which is releasably held in closed position by a U-shaped line of hookless fasteners 30 having a tab element 31 which, in the closed condition of the hookless fasteners, may be secured by a padlock to a stirrup 32 on an end portion of the top 16.

The improved luggage case to which the present irnprovements are applied possesses all of the desirable attributes of a soft-sided case, as it is not only attractive in appearance but extremely light and easy to handle. Additionally, it has reinforced rigid ends which permit the case to retain its normal rigidity and form. Due to the construction described and as shown more clearly in FIGS. 1 and 3, all of the edge portions of the Hexible fabrics of the various walls are joined together and secured within the resilient welts 20 which externally surround the rigid but yieldable ends of the luggage case. The projecting welts 20 serve as bumpers or cushions to absorb blows or strains which might be imposed directly on the ends of the luggage case and, in addition, the end wall construction which includes the rigid panel portions 23 and the resilient or deectable end tips or caps 24 especially adapts the case to the hard usage and abuse to which air travel luggage may be subjected. If the luggage case is subjected to a shock, bump or pressure from any direction, the resilient tips or caps 24 on the ends of the end wall panel portions 23 may bend, iex or distort in any direction and thus absorb the pressure or bump without strain on the rigid panel portions 23. As an example, if pressure is applied to the top of the luggage case, the tips 24 of the ends will depress, whereas if undue pressure is directed against the ends of the case, the tips or caps 24 will bow inwardly. Should undue force be applied to the soft front or rear walls 0f the luggage case, this will in elect tauten the covering material and again the tips on the ends will ex to keep the flexible covering material from ripping or tearing.

The improved luggage case end wall construction is simple but strong and durable and is well adapted for the purposes set forth.
