Abstract
A cover for the body and a similar cover for the lid of a luggage case, each of which covers is made up of a number of pieces of sheet material pre-cut so that when the pieces are sewn together the cover assumes a three dimensional form which enables it to be manually fitted over the corresponding body shell and lid shell and fastened in close tight-fitting relation to the shell. The side panels are of relatively thin sheet material and the end areas are constituted by several parallel strips of relatively thick sheet material stitched together and also stitched in overlapping relation to the side panels. The edges of the end strips are sewn together so as to form a projecting rib surrounding the body and the lid for a pleasing appearance and for assuming wear and abrasion of the end of the luggage case. Overall weight of the luggage case is reduced by employing relatively thin sheet material for the major area of coverage and relatively thick sheet material only at the ends of the luggage case.

Description
This invention relates to a cover for a luggage case having a body shell and one for the lid hinged together, such as an attache case, and to a method of constructing the cover from a number of two-dimension pieces of sheet material, assembled as by stitching them together to provide a three-dimensional form adapted to be installed and fitted manually to the body shell and lid shell.
A principal purpose of my invention is to construct a cover for a two-part hinged luggage case which simulates the appearance of being of relatively thick sheet material throughout but in fact having the major part of the covering material of relatively thin sheet material and only the end areas of relatively thick sheet material.
A further purpose of my invention is to provide a relatively simple manner of construction of a cover for a luggage case which reduces labor cost and which at the same time provides a novel and pleasing appearance for the luggage case.
In the prior U.S. Pat. No. 3,921,768 to Samson Gorky issued Nov. 25, 1975, a method of making a cover for a luggage case is disclosed in which a number of two-dimensional pieces of sheet material are stitched together to provide a three-dimensional form which is capable of being fitted manually over the shells of the body and the lid therefor. In this patent, all the pieces of sheet material are the same thickness and because of the thickness of the sheet material considerable weight is added to the luggage case.
According to my invention, the weight added to the luggage case by the covers fitted over the body and the lid is reduced simply by providing a relatively thin sheet material for the major area of the cover and stitching end sections thereto of thicker sheet material. At the same time the end sections are so stitched together as to cause projecting ribs to be formed surrounding the entire body and lid, which ribs serve the purpose of welting in assuming wear and abrasion on the luggage case. At the same time, the projecting ribs provide a pleasing appearance and a decorative design.
I am aware of U.S. Pat. No. 2,661,823 to E. M. Goetz, issued Dec. 8, 1953, wherein binding strips are stitched to the ends of a cover for a luggage case. Such binding strips, however, serve only to add structural strength to the cover at the point of attachment to the luggage case frame.
More specific details of the structure and method of making my cover for luggage cases are described hereinafter in relation to the accompanying drawings, wherein:
FIG. 1 is an isometric view showing the overall appearance of an attache case having a cover embodying my invention;
FIG. 2 is a view showing, in a single plane, the number and shape of pieces of sheet material constituting a cover for a shell forming one part of a luggage case;
FIG. 3 is a view, showing the appearance of the cover pieces of FIG. 2 after partial assembly;
FIG. 4 is a fragmental sectional view, taken on the line IV--IV of FIG. 3 showing in profile the relation of the end pieces, as stitched together, and the greater thickness of sheet material employed by the end pieces in relation to that of the side panels;
FIG. 5 is an isometric view, showing the appearance of the cover after the final step of assembly and its condition ready for installation or mounting on the shell; and
FIG. 6 is a sectional view, on enlarged scale, of a cover as installed on the corresponding shell.
Referring to the drawings, it will be seen that I provide a cover 10 for a luggage case, illustrated in FIG. 1 as of the type having two similar dished or box-like shells, one a body shell and the other a lid shell, the two shells being hinged together along one edge so as to be swung into mating relation.
As shown in FIGS. 2, 3 and 4, the cover 10 for a single shell, either the body shell or the lid shell, is made up of a total of five pieces of sheet material, consisting of a main or side panel piece 11, two end pieces or strips 12 and 12a, and two end pieces 13 and 13a. The side panel piece 11 varies in size conformably to the size of the shell to be covered, but is of generally rectangular shape. The end pieces 12 and 12a are similar to each other but one is the mirror image of the other. Likewise, the end pieces 13 and 13a are generally similar to each other, one being a mirror image of the other.
It will be seen that the positioning of the cover pieces in FIG. 2 is such as to indicate generally the manner in which the pieces are moved together for the initial step of assembly. Thus, pieces 12 and 12a are moved into overlapping relation to the adjacent margin of the central main piece 11 and stitched together along a line 14 spaced from and paralleling the straight inner edge of the piece 12 or 12a. As will be seen in FIGS. 3 and 4, the pieces 12 and 12a overlap the opposite edges of the central main piece 11 but not to the extent of the full width of the piece 12 or 12a. This is significant as it allows the edges of pieces 13 and 13a to be bent up and matched to the outer bent up edge of the pieces 12 and 12a, to enable them to be stitched together by a line of stitching 15 extending through the double thickness of the bent up edges, so as to form the decorative ribs 16 (FIGS. 3, 4 and 6). FIG. 4 shows clearly the relative thickness of the central main piece 11 and of the end pieces 12 and 12a.
Due to the curvature of the outer edge of pieces 12 and 12a and the curvature of the edge of pieces 13 and 13a, when the pieces 13 and 13a are fully stitched to the pieces 12 and 12a, the assembly of the two-dimensional pieces assumes the three-dimensional form of cover 10 as clearly shown in FIG. 5. In this form, the cover 10 is manually fitted over the shell 17, with the peripheral excess of the cover being bent over and back into the interior of the shell and tacked or stapled to the shell, which is of fiber board or similar nature. A lining 18, of textile material is then fitted into the interior of the shell 17 so as to overlap the edges of the end pieces 13 and 13a. This provides a decorative inside surface for the body and lid of the luggage case.
The identical procedure is followed to assemble the cover for the body shell and the shell of the lid.
The final steps in the assembly of the luggage case involves attaching various fixtures and fittings such as the hinges (not shown), the handle 20 and the locks 21.
It will be seen that the above described method which I have devised for assembling the various pieces of sheet material into a three-dimensional cover adapted to be manually fitted over the shells of the body and lid provides a relatively simple procedure which reduces the amount of time for the assembly of the cover and consequently the labor cost involved. Any suitable type of sheet material may be employed to make the cover. However, a vinyl sheet material is a good practical material which presents a pleasing appearance and is serviceable. Variations in the contour of the pieces of sheet material may be made depending upon the shape of the shells to which the cover is to be applied.
