The improved carrying case comprising the present invention has been designed primarily for use by students for the unitized one-handed transportation of a heterogenous collection of items such as text books, note book-s, leaflets, writing and drawing instruments, and other school supplies and personal effects too numerous to mention. The invention is also capable of other uses with or without some modification as desired. It may be used as a compactable brief case for carrying business papers, correspondence, documents, sales receipts, drawings and a wide variety of other written or printed material. However, irrespective of the particular use to which the invention may be put, the essential features thereof are at all times preserved as herein described.

Structurally, the carrying case of the present invention differs widely from conventional carrying or brief cases although, in use it may look somewhat like a brief case. Functionally however, the present carrying case dispenses with some of the non essential characteristics of conventional brief cases considering the use to which the present carrying case is to be put while in other respects the present carrying case presents distinct advantages over conventional carrying cases.

As distinguished from at envelope-type cases adapted to be carried by tucking the same beneath the arm the improved carrying case of the present invention is primarily distinguished, inter alia, by a handle for carrying purposes. In this connection handle-equipped cases may be divided broadly into two general classes, rigid or eX- ible. Rigid type carrying cases, sometimes termed attache cases, are of a box-like design and consist of two rigid sections hingedly connected together at the bottom and adapted to be closed upon each other at the top with a handle on one or both sections at the top for carrying it. A latch usually of the locking type holds the sides against falling open. Flexible type carrying cases with or without bellows ends comprise either a single compartment envelope design with a hinged jaw-type entrance closure or two hinged sections closing at the top and maintained in their closed position by either zipper type fasteners or latching and locking devices of the iiip over type similar to trunk locks. Here again handles are provided at the top opening, and, the case would fall open if not physically held closed. Individual smaller compartments or pockets, if present, are merely side pockets and do not receive the main load. They are essentially' single compartment cases.

Although the carrying case of the present invention may be classied as of the ilexible type it differs widely from conventional exible type carrying cases in many respects, as previously stated. In addition to its being provided with a handle, further differences reside in the fact that the present carrying case is a multiple compartment carrying case. Two main sections are illustrated in the present invention which are completely isolated from and out of communication with each other yet both are individually and simultaneously accessible instantly without manipulation of a lock. Another diiference resides in the handle placement and the effect of the handle support upon the carrying case as a whole. Whereas, with conventional flexible type carrying cases, the handle invariably is positioned at or adjacent to the entrance opening of the carrying case, in the present structure the handle is disposed at a point above and shielded from the entrance opening for both sections of the carrying case. Numerous other differences will readily become apparent as the nature of Patented Feb. 27, 1968 the invention is further explained and understood including rain and water protection, visibility of contents when open, automatic closure when carried etc.

Briey, the carrying case of the present invention is in the form of a flexible saddle which is draped over an elongated central rigid supporting bar, and includes stirrup portions or sections which hang downwardly in parallelism on opposite sides of the supporting bar. Oneor more pockets, for the retention of various articles may be formed, as desired, on the inside face of each stirrup portion so that the pockets on the two stirrup sections face each other when the stirrup portions hang in carrying position on the supporting bar. A supporting handle is attached to the center of the supporting bar centrally thereof and overlies the saddle arch. y

As thus supported in carrying position the pockets and contents are electively closed and concealed as when the material of the saddle is of an opaque nature as is contemplated according to one form of the invention. If desired, however, the inside wall of the pocket can be transparent and the contents are readily revealed but only when the case is in open position. On the other hand, the contents of the various pockets can be made visible from the outside as well as the inside and with the bag open or closed if all the material of which the case is made is transparent or nearly transparent. This latter form has appeal to a user when the contents are not confidential and has particular attraction for students who also find it desirable to paste stickers, banners and the like on the inside of the stirrup pockets for display through the walls ofthe stirrup portions.

Another advantage of a carrying case embodying the invention is the waterproof protection afforded its contents. Whereas with conventional carrying cases the closure edges of the outside walls are exposed upwardly even though maintained closed either in abutting relation by a porous zipper fastener, or in slightly overlapping relation by a narrow fold-over ap, the interior of the case is subjected thereby to the entrance of moisture by drippage or otherwise, the carrying case of the present invention is not subject to such entrance of moisture inasmuch as the imperforate saddle arch covers the pocket openings and sheds moisture on both sides thereof, thus shielding the contents of the carrying case. The invention is further characterized by being waterproof up to the height of the pockets if set down in a water puddle.

Another object and advantage of the present carrying case over conventional iiexible type carrying cases resides in the improved ease of accessibility to the contents of the case. By laying the case on either side and then unfolding the other side in the manner of opening a book, all of the various article-containing pockets are opened for immediate access. Moreover, where the material of the carrying case is transparent, the location of the specific articles in the pockets is readily apparent and the contents of other pockets need not be disturbed. Thus, time is not wasted tumbling through the various pockets for a given article.

A further advantage of the present invention resides in the fact that whereas conventional exible type carrying cases are usually provided with rigid bottom walls and semi-rigid side walls so that they possess appreciable thickness, even when devoid of contents, the carryingcase of the present invention is normally of extremely small width, viz. thickness and will accommodate the reception of an appreciable number of small articles without perceptibly increasing its overall width. Thereafter, the placement in the carrying case of additional articles will cause the carrying case to automatically adjust itself to the overall width of the articles contained therein but in no instance will the carrying case be of appreciably greater width than such over-all article width.

' features of the invention are not altered.

A similar and related advantage of the present invention resides in the fact that regardless of the number or size of thearticles contained within the carrying case, such articles are at all times securely held within the pockets provided for them against looseness, shifting of position or rattling, the various pockets automatically adjusting themselves to the size and, toa certain extent, to the shape of the contained article. Y

Yet another advantage offered by the carrying case of the present invention resides in the fact that when the case is empty or contains only flexible sheet material which will not be damaged by coiling, the case may be rolled into the form of a tube on the nucleus of the rigid supporting bar and thus rendered suitable for packing and storage or convenient for underarm support. v

Finally, although provision might be made for individual closing or sealing of the various pockets associated with the present carrying case such is eliminated because closure is automatically provided collectively when the case is lifted in actual use and such articles as maybe contained ltherein provide and also find stable support within their respective enclosures since all of the pockets are generally in an upright or vertical position except when the case is 'open for access thereto.

The provision of a carrying case ofthe character 'briey outlined above being among the principal objects of the invention, a further object is to provide such a carrying case wherein economy of manufacture is readily attainable by its structural organization, a judicious choice of materials and its final fabrication methods. For extreme economy of manufacture, the material selected for construction of the exible saddle may be a suitable and inexpensive commercially available plastic sheeting such as polyethylene sheeting, either transparent, translucent lor opaque, nylon sheeting, vinyl glass sheeting or the like. One particular polyethylene sheeting material which has been found highly satisfactory for use in construction of Y the saddle is the sheet material known as Mylar and which is manufactured and sold by E. I. du Pont de Nemours of Wilmington, Delaware, under that trademark. This material is extremely strong and ,possesses a durability which exceeds that of most k-nown plastic sheeting materials. All of such materials lend themselves readily to high frequency resistance seam welding and thus, when employed for the construction of the saddle, the necessary seams may be made economically by rapid welding and sealing operations. Where utmost economy of manufacture is not a consideration, such materials as canvas or other textile fabrics, leather and the like may be employed for construction of the saddle and the necessary seams may then, if desired, be sitched and sealed. Irrespective however of the specific materials employed and of the methods of assembly utilized, the essential Further objects include the provision of a carrying case which is devoid of fastening devices, clamps, corner fittings or other reinforcements, yet is rugged and durable and is unlikely to get out of shape; the case is one in which the flexible saddle portion thereof may be stamped or cut from a single elongated rectangular blank of sheet material so that there will be no excess Waste or scrap;

Vheretofore expressly enumerated, will readily suggest themselves as the following description ensues.

In the accompanying two sheets of drawings forming 4 a part of this specification, one illustrative embodiment of the invention has been shown.

In these drawings:

FIG. l is a side elevational view of a carrying case constructed according to the .present invention;

FIG. 2 is rear side elevational view of the structure shown in FIG. l;

FIG. 3 is a sectional view taken substantially along the line 3-3 of FIG. 1;

FIG. 4 is a sectional view taken substantially along the line 4-4 of FIG. 1 but showing the carrying case lled with typical school supplies; and

FIG. 5 is a bottom plan view of the carrying case, showing the same in an opened position for full accessibility.

Referring now to the drawings in detailand in particular to FIGS. 1 to 3 inclusive, the carrying case of the present invention, in the form illustrated in these views, comprises three principal parts, namely, a exible saddle portion 10, a rigid supporting bar 12, and a handle 14. The saddle 10 is supported in its entirety by the supporting bar, and the latter, in turn, is suspended from the handle 14 when the carrying case is in use. The saddle 10, inV the illustrated form thereof, is formed of a suitable transparent or translucent flexible plastic sheet material such as polyethylene. The supporting Ibar 12 is preferably formed of wood, although other lightweight materials such asV aluminum are contemplated. The handle 14 may be molded of a suitable plastic material such as a phenolformaldehyde condensation product although other materials such as metal or leather covered metal can be used.

The supporting .bar 12 is of elongated rod-like design and, as best seen in FIG. 3, it is generally rectangular in transverse cross section except for the provision of an arcuate convex upper surface 16. The supporting bar 12 thus is provided with spaced vertical side surfaces 18 and 20, and a flat horizontal bottom surface 21 which may be as wide horizontally as desire-d.

The saddle 10 is draped, so to speak, over the supporting bar 12 and hangs downwardly on opposite sidesY thereof, thus establishing a saddle arch section 22 and two freely hanging depending

side stirrup sections

24 and 26 respectively. The saddle arch section 22 overhangs the opposite ends of the bar 12 a slight distance as indicated at 27. Article-retaining pockets are provided on the opposed inside faces of the two stirrup sections in a manner that will ybe described in detail presently.

The handle 14 may ybe of any conventional design or construction provided that it preferably is mounted for pivotal movement. AIn the illustrated form of the invention the handle 14 is formed of a suitableplastic material as heretofore mentioned and it is of inverted U-shape design. It includes a pair of diverging tapered side or leg portions 28 and a relatively thick connecting bight portion or grip section 30. The free ends of the side portions 28 are turned laterally as at 32 and extend pivotally into sockets which are provided in a pair of base fittings 34 which are secured upon the saddle arch 22 by rivets 36. The rivets extend through both the saddle arch and the supporting bar 12 to provide a unitary assembly. The handle 14 is thus pivotally mounted on the saddle arch and receives its tensional reaction support from the rigid supporting bar 12. The rivets 36 serve the dual function of retaining the fittings 34 in position above the supporting bar 12 and of anchoring the saddle in place thereon; If desired, the arch section 22 may be cemented co-extensively to the supporting bar 12 by a transparent adhesive.

Referring now additionally to FIGS. 4 and 5, the inside face ofthe stirrup section 26 which overhangs the side surface 18 of the supporting bar 12 is provided with two article-retaining

pockets

40 and 42, while the inside face of the stirrup section 24 which overhangs the side surface 20 is provided with a single article-retaining pocket 44. The pockets `40 and 42 are partial width pockets, in a horizontal direction, while the pocket 44 is a full width pocket. All of the pockets open upwardly` towards the -bar 12 and have their rim regions disposed a slight distance below the saddle arch 22.

It should be borne in mind that in the various view of the drawings, the disclosures have been made on the basis of transparency of the plastic material from which the saddle is formed, Thus, for example, in FIGS. l and 2, certain seam lines and edge lines have been drawn as full light lines to indicate that they are -background structure which is seen through an overlying transparent thickness of material. Where two thicknesses of overlying material are involved, no attempt has been made to illustrate the background structure.

Although the saddle can be made crosswise from roll stock of a width equal to the unfolded length of the saddle element as a continuous process of folding the edges, seaming and cutting to the 'length of the saddle, each saddle 10 preferably is made from a single elongated blank of the transparent sheet material with the opposite end portions of the blank folded inwardly (ie. upwardly as viewed in FIG. 3) toward the center of the lblank in opposite directions but on the same side of the blank along wide fold lines and S2 (FIG. 5) which ultimately become the bottom Walls or edges of the

pockets

40, 42 and 44. The fold line 50 accommodates the

pockets

40 and 42 and the fold line 52 accommodates the pocket 44. After such folding operations, the fold which em- -anates from the fold line 50 is heat sealed along marginal (vertical) seam lines or areas 54 and along a central seam line or area 56 to provide the two pockets 40` and 42. Similarly, the fold which emanates from the fold line 52 is heat sealed along marginal seam lines or areas 58 to provide the single wide pocket 44.

While the construction of the saddle 10 from a single elongated blank of plastic sheet material as described above represents a convenient and preferred method of forming the saddle and results in economy of manufacture since it simplifies material-handling procedures, as well as eliminating scrap or waste material, it is also possible to form the saddle by using three separate sheets of exible transparent material including a main sheet for the body portion of the saddle 10, a lining sheet for the pocket 44, and another lining sheet for the two

pockets

42 and 44.

In such an instance seam lines will be provided at the bottoms of the various pockets instead of fold lines.

While the provision of a single pocket on one of the stirrup portions, and two pockets on the other stirrup portion represents a convenient arrangement of pockets suitable for use when the carrying case is employed for school purposes, it is obvious that other pocket arrangements involving multiple pockets in excess of two on either or both stirrup portions may be employed. Additionally, the size and shape of the various pockets may be varied as desired. For example, elongated na1- row pockets may be provided for reception of individual writing implements such as pens or pencils. If desired a triangular pocket may be provided to receive the corner region of a draftsmans ruling triangle.

In FIG. 4 the carrying case 10 is shown as being put to a typical use in the transportation of school supplies. A hook or the like 60 is disposed within the pocket 44; a notebook 62 and a pencil box 64 is disposed in the pocket 40; and a lunch packet 66 and an article of fruit 68 is disposed in the pocket 42. It is to `be noted that due to the flexibility of both the outer Walls and the inner walls of the various pockets, the various articles cause the pockets within which they are disposed to bulge both outwardly and inwardly of the carrying case as a whole. The carrying case thus is automatically variable in width to accommodate the combined widths of articles contained therein. In no given instance however is the overall width of the carrying case appreciably greater than the overall width of the contents thereof. Where extremely wide objects are contained in the various pockets, the inside walls of the

pockets

40 and 42 may abut against the inside wall of the pocket 44 but, despite this fact, no appreciable stress will be applied to the Various seam lines unless, of course, the pockets are unduly stuffed.

The illustration of FIG. 5 shows that the carrying case 10 may conveniently be opened for convenient and simultaneous access to all three of the

pockets

40, 42 and 44. To thus expose the pockets for access purposes it is merely necessary to lay the carrying case on one side and open the other upwardly and outwardly on a planar supporting surface as shown in this view with the handle 14 underlying the saddle 10 and resting on its side. A feature of the present invention which is prevalent when the saddle is formed of transparent or nearly transparent material resides in the fact that the contents of the various pockets are visible through the inside walls of the pockets when the carrying case is spread out as shown in FIG 5 and thus it is unnecessary to fumble through the various pockets in search of a given article.

In a modified form of the invention it is contemplated that the material of the saddle be formed of an opaque material such as opaque polyethylene sheet material, treated cloth such as canvas, leather, or a leather substitute. Where the particular material employed is not readily susceptible to heat sealing operations, the various seam lines employed may be eected by suitable stitching and sealing operations.

The invention is not to be limited to the exact arrangement of parts shown in the accompanying drawings or described in this specification as various changes in the details of construction rnay be resorted to without departing from the spirit of the invention. Therefore, only insofar as the invention has particularly been pointed out in the accompanying claims is the same to be limited.
