S. PLATT CARRYING CASE July 5, 1966 Filed May 2l, 1965 fz'z VER 227.27

I S/D/VEV PLA7'7' E L/ZJMLMQMZMM United States Patent O 3,259,217 CARRYING CASE Sidney Platt, Highland Park, Ill., assignor to Platt Luggage, Inc., Chicago, Ill., a corporation of Illinois Filed May 21, 1965, Ser. No. 457,623 7 Claims. (Cl. 190-48) The present invention relates generally to an improved article of hand luggage and more particularly is directed `to a `substantially strengthened carrying case.

Generally those forms of luggage which are adapted Ito be carried by hand must be relatively light in weight so as to avoid adding unnecessary weight to the load being carried. At the same time the article must have -a relatively rigid structure so that it is adaptable for carrying relatively heavy loads, such as catalogs, samples, etc., without being twisted or deformed.

It is an object of the invention to provide an improved carrying case of the above character.

Another object of the invention is to provide an improved unitary wall construction for a carrying case so as to increase its structural strength and to enhance its load-bearing properties.

Another object of the invention is to provide a carrying case having `an improved wall construction so as yto provide a more rigid structure adaptable for transporting relatively heavy objects such as catalogs and the like.

Another object of the invention is to provide an improved, unitary side Wall and bottom 'wall structure integrally fastened to rigid end walls and having an improved lid piece construction so as to increase the load-bearing properties of the structure las well as to increase the degree of protection afforded its contents.

A further object of the invention is to provide a rigid carrying case which is attractive in appearance and extremely durable in use.

Other objects and advantages of the invention will become apparent with reference to the following description and the accompanying drawings wherein:

FIGURE l is a partially broken away perspective view of an article of luggage constructed in accordance with the present invention;

FIGURE 2 is a fragmentary sectional view taken along lines 2 2 of FIGURE l;

FIGURE 3 is a fragmentary sectional view taken along line 3 3 of FIGURE l; and

FIGURE 4 is a sectional view taken along line 4-4 of FIGURE 1.

Referring to the drawings, a carrying case in accordance with the present invention generally includes a pair of spaced rigid end shells and 12, each provided with re spective opposed, inwardly facing

peripheral flanges

14 and 16, extending around substantially the entire periphery of the

respective end shells

10 and 12, and for-ming inwardly facing opposed grooves, or

channels

18 and 20. A unitary member 22 including a structurally reinforced ibottom wall 24 and a pair of

side walls

26 and 28 interconnects the

end shells

10 and 12 so as to form lan integral open-topped enclosure. Although `the article is thus initi- -ally formed in an open configuration, it is adapted to be closed by a pair of overlapping lid pieces and 32, which extending longitudinally along and are pivotally secured to the

side walls

26 and 28 respectively. The underlying lid piece 30 is provided with a suitable handle 34 of -a size which conveniently projects through an aperture 36 in the overlapping lid piece 32.

The unitary member 22 is generally U-shaped in crosssection and is formed of a single sheet of material so as to form a durable integral structure. The bottom wall 24 of the unitary member 22 is provided with structural rein- Iforcement by disposing a reinforcing strip or plate 38 on 'ice the inner surface of the bottom wall 24 in overlying relationship and generally coextensive therewith. The plate 38 is preferably secured to the bottom wall 24 by gluing I and is in turn overlaid by a thin layer of a leather or leatherette material (not shown) so as to retain an a-ttractive appearance. Since the bottom wall 24 carries a substantial amount of the stress, when a load is carried in the article, Aand is; generally subjected Ito relatively hard usage, the strip 38 is lfurther secured to the bottom wall 24 by the provision of a plurality of suitable rivets 40.

The bottom wall 24 is generally pro-vided with suitable feet 42 which project downwardly from the lower surface thereof and serve to support the article, when it is in a vertically upright position, as shown in FIGURE 1. Preferably the Vfeet 42 are secured to the bottom wall 24 by the rivets 40 `so that the plate 38, the lbottom wall 24, and the feet 42 define an integra-l rigid unit.

The bottom wall 24 and the

side walls

26 and 28, which as previously mentioned, `are an integral unit, are preferably fabricated of a relatively durable material, which is attractive in appearance, such as a laminated leatherette.

The bottom `and side walls, forming the unitary member 22, `deiine an openended, open-topped structure the ends of which are closed by the

end shells

10 and 12. The

end shells

10 and 12 are forme-d of a rigid molded material generally similar in appearance to that of -the -U-shaped member 22, but having a relatively greater thickness so as to provide increased structural strength. The

end shells

10 and 12 each comprise a generally flat rectangular sheet of material formed Ito include a panel 44 Vand 46 respectively and the associated

peripheral flanges

14 and 16, each of which extends outwardly from its panel and is then reversed upon itself to provide spaced parallel walls, which define the inwardly facing peripheral grooves or channels 13 and 20 extending between the walls. The

channels

18 and 26 on

opposite end shells

10 and 12 are aligned with each other, and are adapted for receiving the end edges ofthe U-shaped member 22.

The flange 14 is formed as an integral part of the panel 44 and generally serves to structurally reinforce 'the `article. More particularly, .the flange 14 extends -around substantially the entire -periphery of :the .panel 44. The flange '14 thus substantially strengthens the panel `44 so .as to prevent bowing or warping, `as well as protecting the outer surface of the panel 44 from being -defaced, scuied, or otherwise damaged, when :subjected to hard usage. In addition, the walls `of the

flanges

14 and 16 which define the channels 18 Vand 20 substantially strengthens and supports the attachment 'of 'the end shells :10 and 12 .to the member 22, as is subsequently explained in detail.

The end shells 10 and .12 [are attached to the unitary member 22 by disposing ,the outer endedges .of the mem` ber 22 into the opposed aligned channels 1|8 and 20 defined by the parallel walls of the flanges 14 and i116. These `outer end edges are secured in the channels `18 and 20 by lrows of

stitching

48 and 50 respectively, extending through the end edges and through the parallel walls of the

flanges

14 and 16, while the ioutwardly extending ends of .the flanges `,14 and 16 define a peripheral bead or rim 51 and '52, extending .around substantially the entire periphery of the end shells 10 .and 1'2 respectively. The end shells `10 and 12 are thus integrally connected with Ithe unit-ary member 22. In addition, as shown in FIG- URES 2 `and 3, the ends of the plate 38 also are secured within the

channels

18 and 20 so as to `strengthen the overall, load-bearing lproperties of the article.

To further reinforce the upper ends of the

dlanges

14 and 16 corresponding strips of rela-tively rigid materials 53 and 54 are disposed in the channels `1'8 and 20 respectively, extending between the upper ends of the

side walls

26 and 28 and are secured by the rows of stitching 48 and Sti. The

yflanges

14 and 16, thus provide substantial .structural reinforcement for the article by uniting several layers of material and securely stitching them together :and yalso form the relatively strong reinforced rim or

bead

51 and 52 on opposite sides of the article. The

beads

51 and 52 extend around substantially the entire periphery of the end shells and 12 so as to greatly strengthen .the article structurally las iwell as to provide a trim end appearance.

Preferably the side walls 26 :and 28 are arranged Ito terminate a suflicient distance below the upper ends of the lflanges l14 `and 16 so that the

lid pieces

36 and 32 may conveniently be secured to the side walls 26 and `23 iat a point spaced -below the upper ends of the

side walls

26 and 28. Thus the `l-id pieces 30 and `32 ,are partially bowed in shape so as to 'lit around the arcuate corners of the flanges '14 and 16, and thereby snugly close off the top sof the enclosure.

Itis quite advantageous to .attach the lid pieces 30 and 62 'to the

side walls

26 and 28 iat a point spaced below the `upper ends of the latter. Such a configuration provides increased access to the interior of the article, since -there is no interference by the lid pieces Iit] and 32, while yielding increased protection for the con-tents, when the

lid pieces

30 and 32 are -in an open position. Since the

side walls

26 and 28 together with the

end shells

10 and 12 extend above the pivot point at which the

lid pieces

30 and 32 `are attached, increased protection is afforded the contents of the article, when the

lid pieces

30 and 32 are in an open position by virtue of the vupwardly extending portions, lwhich in effect form a peripheral ledge 55. Since the lid pieces 30 and `32 are 4generally similar in structure and method of attachment to ,the respective side walls 126 and 28, only the lid piece 32 and its manner of attachment to its associated side wall 26 will be described in detail.

The lid piece 32 generally comprises a relatively narrow flexible strip A56 of material which is rigidly secured ,to 4the side wall 26 and a -generally bowed, relatively larger, molded member 57 comprising a sandwich including -a reinforcing plate 58 and overlying inner 'and outer layers of material (not shown) such as leather, leatherette, vinyl, etc. The member 57 is generally `bowed at one end, as shown, and is pivotally secured to ythe strip 56 by a double row of lstitching 59.

The strip 56 is of approximately .the same length as .the side wall 26 'and yis preferably secured thereto by par- 'allel spaced rows of stitching 60 and 62. To further strengthen the rigidity of this attachment, a reinforcing element `64 comprising an elongated, rigid bar of a material such as steel, is disposed between the `parallel rows of stitching 60 and 62 intermediate the strip 56 and the side wvall 426. The bar 64 is longitudinally coextensive with the strip l56 and is secured at its opposite ends to the strip 56 and the side wall 26 lby rivets 66, which extend through the strip 56, the ibar `641i, and the walls of

ythe flanges

14 and 16. This provides an extremely strong bond between the lid piece 32 and the side wall 26. lMoreo-ver, it can :be readily seen that by fvirtue of its particular design, when the 'article is in a loaded state and is :being carried by the handle 34, most of Ithe stress is concentra-ted, on the rivets 66, securing the

lid pieces

30 and 32 to the reinforced flanges 14 and y16. Thus the greatest stress is `generally .concentrated at the particular portions of the article which are provided with the greatest structural strength.

The molded member 57 comprising the lid piece 32 is secured to the strip 56 by the stitching 59 at a point spaced from the stitching 62 so as to allow the member 57 to pivot about the region intermediate the stitching 59 and the stitching 62. The molded member 57 is bowed, or curved, at its end at which it is attached to the strip 56 a suilicient amount to permit it to snugly fit around the arcuate corners of the

end shells

16 and 12 and rest on the reinforced upper flanged portions thereof, when the lid piece 32 is in a closed position. Thus, as previously mentioned, the contents are protected, even when the

lid pieces

30 and 32 are in an open position, since portions of the

side walls

26 and 28 together with corresponding portions of the

end shells

10 and 12 extend upwardly from the pivot line of the

lid pieces

30 and 32, forming the ledge 55. To further increase the load-bearing properties of the article, the handle 34, which is provided on the lid piece 30, is also secured to the associated reinforcing plate 58 provided on the lid piece 30. Each of the

lid pieces

30 and 32 is also provided with suitable associated latch means 70 so that the article may be conveniently secured in a closed position, when it is being carried or stored.

To increase the usefulness of the article, a plurality of separators or dividers 72 are preferably provided, which divide the interior into discrete compartments. The separators 72 are preferably maintained in position by disposing their opposite ends in the

flanges

14 and 16 and extending the rivets 66 as well as the

stitching

48 and 50 through these ends.

Thus, an extremely strong and durable carrying case has been described which provides excellent protection of its contents, while in both an open and a closed position.
