SHEET 2 BF 2 ATTACIIE CASE WITH TRANSPARENT SIDE WALLS BACKGROUND AND SUMMARY OF THE INVENTION This invention relates to a personal carrying case or attache case having a transparent side wall, and having an overlying opaque side wall cover with means for quickly releasing the side wall cover to expose the case contents for inspection purposes without the necessity for opening the case housing.

In recent years, personal carrying cases frequently referred to as attache cases have come into widespread use as briefcases for carrying business papers, as sample cases for use by salesmen, and as overnight travel cases for persons carrying business papers and a minimum of personal effects.

Due to the increasing need for security precautions in all types of buildings and in common carrier vehicles such as planes, trains and busses, it is becoming more and more commonplace to inspect the contents of hand-carried parcels and carrying cases of persons prior to entering buildings and transportation vehicles. Such inspections, to be effective, are time consuming and result in considerable delays when a large number of persons are awaiting entry into a building or vehicle.

It is desirable therefore to provide a carrying case which provides a relatively quick and easy means for facilitating a thorough inspection of the contents, and to minimize the delays necessitated by such inspection.

In some cases it is desirable that the attache case remain locked; and this would be particularly true where a messenger is carrying important documents and does not have a key to obtain access to the case.

A principal object of this invention is to provide a carrying case having means for quickly facilitating the inspection of its contents.

Another object of this invention is to provide a case having means to allow inspection of its contents without the necessity for unlocking or opening the case.

A further object of this invention is to provide a carrying case having transparent walls for allowing inspection of the contents, and having conveniently releasable opaque cover means for exposing the transparent walls without requiring opening of the case.

Still another object of this invention is to provide a carrying case for these purposes which is just as functional and aesthetically pleasing in appearance as conventional carrying or attache cases.

A further object of this invention is to provide an attache case for the stated purposes which is simple and rugged in construction.

For accomplishing these objects a carrying case comprises a housing consisting of mating box-like members hingedly connected at the bottom edge walls, and having latch means at the top edge walls for closing the housing members. At least one of the housing members has a transparent side wall; and an opaque side wall cover is hingedly attached to that member at the bottom edge to overlie the transparent side wall in the closed position. The transparent side wall and side wall cover have coacting magnetic closure means at least along the top edges thereof which act to maintain the side wall cover in confronting and overlying relation with the transparent side wall. A release means disposed in the top edge wall of the housing member effects separation of the side wall cover from the transparent side wall to release the hold of the magnetic closure means, and this release means is operated by an actuator lever preferably placed close to the carrying case handle for convenient operation. The release means may include extensible pins for effecting separation of the cover from the side wall with cam means for extending the pins. Preferably both housing members have transparent side walls and associated side wall covers.

The novel features and the advantages of the invention, as well as additional objects thereof, will be understood more fully from the following description when read in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIGS-l, 2 and 3 of the drawing are general views of a preferred form of carrying case according to the invention which has the form of a rectangular housing made up of two generally identical housing members 10a and 10b. For convenience of description, since these housing members are substantially identical, common reference numbers will be used for similar parts. While the illustrated case is substantially rectangular in form, the objects and advantages of the invention may be accomplished with a form of case which is more contoured or styled for a pleasing appearance.

Each of the case housing members is a five-sided boxlike member defining, for the case, a side wall 11 and four edge walls which provide for the case a top wall 12, two end walls 13 and a bottom wall 14. The housing members are secured at the bottom wall by hinges l5, and are latched at the top wall by locking latches 16.

The housing member 10a is illustrated as being deeper than the member 10b, and a conventional carrying handle 17 is secured to the top wall of the deeper member 10a. Resilient pads 18 may be mounted on the bottom wall for supporting the case in an upright positron.

Sincethe principal object of the invention is to provide a case having transparent side walls, the housing halves may be molded in their entirety from a transparent plastic material for example, with certain portions such as the several edge walls being made opaque in any desired manner such as by painting or by securing opaque trim material to the edge walls.

In preferred form the exterior faces of the side walls areprovided with shallow recesses 21 defining edge ribs 22 which are adjacent the top and end walls for the respective housing members. The recesses 21 may extend around the bottom edge and be provided also in the bottom walls 14. These shallow recesses are provided for accommodating the side wall covers which are fabricated from thin sheets of a relatively stiff material, such as sheet metal or plastic for example, and which include inturned bottom flanges which are received in the above mentioned recess portions in the bottom walls 14.

As best seen in FIG. 2, the side wall covers are secured to the respective housing members along the bottom edge wall by means of piano hinges 24. When the 1 side wall covers are in closed position as best seen in FIG. 1, the covers are neatly received within the shallow recesses 21 to form an aesthetically pleasing configuration; and when the side wall covers are in open position as best seen in FIG. 3, the transparent portions of the side walls are uncovered to expose the contents of the case.

Stop cords 25 may be provided for limiting the outward swing of the side wall cover 23. Alternatively, hinged braces might be provided.

It is well known, attache cases of the type described frequently are divided into two compartments, one

serving as a file compartment which may include an expanding pocket tile for example, and the other serving as a personal compartment for carrying personal articles on an overnight trip for example, with a separator partition closing the personal compartment. In FIG. 3 there is shown an expanding pocket file and this would preferably be fabricated of'a transparent plastic material. While the above mentioned separator partition might be opaque, the contents of the case would still be fully visible where transparent side walls are provided at both housing members.

A preferred means for retaining the side wall covers in the closed position is a magnetic latching means. Preferably this means may take the form of magnet strips 31 placed within the recesses 21 adjacent to the top walls 12. These magnet strips, best seen in FIGS. 3 and 7,'may preferably take the form of a resilient tape havingembedded magnetic particles, which is readily secured to the case housing members. If the side wall covers arefabricated of a magnetic metal, these covers would of course be attracted to the magnet strips to effeet the magnetic closure. If the side wall covers are fabricated of a non-magnetic material, it will be necessary to provide elements of magnetic material along the top edge inner face of the respective side wall covers for confronting engagement with the magnet strips 31 or other magnet means. While the magnet strips and confronting magnetic faces are illustrated for only the top edge of the side wall and covers, it will be appreciated that these magnetic latch means maybe extended downward adjacent to the end walls of the housing members.

A preferred form of release mechanism for the side wall covers is best seen in FIGS. through 8. This mechanism is made up of separate and substantially identical mechanisms for each of the housing members 10a and 10b, and the following description will refer essentially to the mechanism for the member 10a. As

best seen in FIG. 5, a pair of pins 41, having integral radial flanges intermediate their ends, are disposed in counterbored holes 42 which extend transversely through the top wall 12, with the smaller bore opening from the outer face of the top wall and the counterbore opening to the inner face of the top wall. The pins are retained within the holes 42 by means of an elongated cam bar 43 disposed in an elongated groove 44 which opens to the inner face of the top wall 12 and which intersects the two counterbores. The cam bar 42 is retained, in turn by means of cylindrical guide members 45 which are received and retained within the counterbores by means of snap rings 46 for example. The guide members are provided with a transverse slot for receiving and guiding the cam bar, and also with an axial recess for accommodating the inner ends of the pins 41.

The pins 41 are urged inwardly against the cam bar by means of compression springs 47 confined within the counterbores and bearing against the pin flanges. In the normal position of the cam bar, the inner ends of the pins are received in notches 48 provided in the cam bar, which permit the outer ends of the pins to be completely received within the respective holes. The notches 48 define cam surfaces which function to extend the pins outwardly as will be described.

As best seen in FIG. 5 a cylindrical recess 51 defines an extension of the cam bar groove 44; and a compression spring 52 disposed in this recess bears on the end of the cam bar to normally urge the bar toward the left as seen in- FIGS. 5 and 7, wherein the cam bar notches are positioned to receive the pins 41. Movement of the cam bar toward the rights, as seen in these Figures, ef-

' fects camming of the pins 41 outwardly to separate the side wall cover 23 from the magnet strip 31 and thereby break the magnetic latch permitting the side wall cover to swing open as seen in FIG. 3 and 4.

The cam bar 43 'is shifted to effect this release by means of an actuator lever 55 which is fixed to the cam bar and projects upwardly from the top wall 12 through a slot 46 adjacentto the handle 17. As best'seen in FIGS. 3 and 4, the two actuator levers 55,-for the release mechanisms of the respective housing members 10a and 10b, are positioned in side-by-side relation so that they may be readily engaged simultaneously by the thumb of the user carrying the case by means of its handle. As seen in the drawings, movement of the actuator levers toward the handle will effect the release of both side wall covers. In this manner the covers may be readily released for inspection of the carrying case contents and enable inspection of the case very quickly and easily. Following inspection, the side wall covers are simply swung into' the latched position where they are retained magnetically.

While only two release pins 41 are shown for each housing member, it will be appreciated that a mechanism may be provided for actuating additional release pins, and that release pins may be arranged in the end edge walls 13. As-described above, it is preferred that the side wall cover be relatively stiff to effect release of the magnetic latch, particularly if the magnetic latch means is extended along the end edge walls. If desired, stiffening ribs may be incorporated in the structure of the side wall covers.

What has been described is a carrying case suitable for use as an attache case or for other purposes having convenient means for enabling inspection of the contents of the case without the necessity for opening the case.

A particular advantage of the use of this type of case is in situations where valuable articles are carried in a case by a messenger who does not have a key for opening the case.

Another principal advantage of a case of this type is that it enables quick inspection, which is particularly useful in situations such as the boarding of aircraft where there may be a great number of cases to be inspected within a relatively limited time. It is also useful for enabling the inspection of cases used for briefcases in office buildings or plants where a large number of persons are seeking ingress or egress within a relatively short time span.

A particular feature of the construction according to the invention is that it accomplishes the desired purpose and yet enables the fabrication of a carrying case which is quite conventional in appearance and which may include any of the usual aesthetic features which will enhance the sale of such cases.

Another feature and advantage of the invention is the use of a simple magnetic type latching means and the use of an associated simple and effective release means for the side wall covers.

While a preferred embodiment of the invention has been illustrated and described, it will be understood by those skilled in the art that changes and modifications may be resorted to without departing from the spirit and scope of the invention.
