Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a file folder for an attache case. 
     Attache cases have a generally rectangular container and a lid hinged to the container. It has been well known to provide a file folder mounted in the attache case lid. The file folder consists of an outer wall and one or more dividers interconnected by webs or gussets along side edges, in accordion fashion, to create multiple expandible pockets. 
     In use, the attache case is normally set flat on a surface and the lid is opened and raised to a vertical attitude. In that attitude, the pockets can hang free, overhanging to some extent the container. When the pockets are not in use and they are hanging free, they are in the way of the convenient and orderly removal and replacement of files in the main container. To eliminate the overhanging problem, it has been conventional practice to provide straps at the sides of the lid, the straps having fasteners at their free ends cooperating with the outer wall of the file folder to hold the file folder snugly within the confines of the lid. 
     The straps do flap about. The straps require manipulation to unfasten and fasten them when opening the pockets and returning the pockets of the file folder snugly against the lid, respectively. Even with these disadvantages, the straps have been used to retain the file folder within the confines of the lid for at least fifty years. 
     SUMMARY OF THE INVENTION 
     It has been an objective of the present invention to provide a multiple pocket file folder with an automatic closing mechanism. 
     This objective of the invention has been attained by providing a spring closure mounted on the lid. More specifically, a U-shaped spring wire is connected at its free ends to the rear wall of the lid adjacent to the hinge connecting that wall to the attache case container. The spring is coiled at its ends adjacent the points of connection to the lid rear wall to create a biasing force toward the main wall of the lid. The free portion of the U-shaped wire spring is secured to an outer divider or outer wall of the file folder to urge the file folder to a closed condition. 
     This spring-biased file folder structure permits the pockets to be opened simply by pulling against the outer wall of the file folder to pivot it outwardly against the force of the spring. When the pockets are emptied or partially emptied, the spring will urge the file folder to lie snugly within the confines of the lid. There are no straps to dangle or to be manipulated in opening and closing the file folder.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIG. 1, an attache case is shown at 10 and has a rectangular container 11 to which a lid 12 is hinged. The rectangular container has a bottom wall 15, a front wall 16 to which a handle 17 is attached, two side walls 18 and a rear wall 19. Similarly, the lid has a top wall 20, a front wall 21, side walls 22 and a rear wall 23. The rear wall 23 is connected by hinges 24 to the rear wall 19 of the container 11. Cooperating fastener elements 25 and 26 are mounted on the front walls of the lid 12 and container 11, respectively, to close and to lock the attache case. Bumper feet 30 are mounted on the rear walls 19 and 23 of the container and lid, respectively, to support the attache case off the ground when it has been set down, thereby protecting the rear surfaces of the case. 
     A file folder 35 is mounted in the lid. The file folder 35 can have one or multiple pockets. As shown in FIG. 2, in the illustrated form of the invention, the file folder 35 has a first divider 36 and a second divider 37. The first divider is connected to the second divider by side webs or gussets 38. The second divider 37 is connected to the top wall 20 of the lid by webs or gussets 39, thus creating two deep pockets 41 and 42. A fabric or leather sheet 40 overlies a portion of the first divider 36 to create a shallow pocket 43. 
     Referring to FIG. 4, it can be seen that an inverted U-shaped wire spring 45 is attached to the rear surface of the first divider 36 that forms an outer wall for the file folder 35. The wire 45 is on the side of the divider facing the second divider so that it is concealed. The ends of the wire are formed with loops 46, the loops being riveted to the lid rear wall 23 by the same rivets 47 that attach the bumper feet 30, as shown in FIG. 3. Immediately adjacent the loops 46 are coils 48 formed in the spring steel wire. The coils 48 serve as coil springs which urge the divider 36 against the top wall 20. The wire has a bight portion 49 that is connected to the divider 36 by a vinyl plastic extrusion 50 (FIG. 4) which is stitched over the wire 45 to the divider panel. The wire 45 is approximately 12 gauge (0.105&#34; diameter) in the preferred form of the invention. 
     In the operation of the invention, the wire 45 normally urges the file folder 35 snugly against the top wall 20 of the lid 12 within the confines of the front 21, rear 23 and side walls 22 of the lid 12. When papers are to be put in the file folder 35, the user merely pulls the outer divider 36 away from the top wall 20, thereby opening outer and inner pockets 42, 43. When the outer divider 36 is released, the file folder 35 closes automatically through the urging of the wire spring 45, thereby returning the file folder to the confines of the lid 12 without the need of straps or other fasteners that require special manipulation. 
     From the above disclosure of the general principles of the present invention and the preceding detailed description of a preferred embodiment, those skilled in the art will readily comprehend the various modifications to which the present invention is susceptible. Therefore, we desire to be limited only by the scope of the following claims and equivalents thereof:
