Abstract
Abstract The invention is directed to a portable file which comprises an open housing with side walls, an end surface and a base; a translatable container within the housing having a plurality of removable file divider walls, protrusions on the side surface of the file divider walls engage angled slots on the container side walls. The file divider walls include a hinged attachment to the housing bottom surface; a lid similar in construction to the "roll top" of a desk covers the open upper surface of the housing in one extreme translated or "rolled" position to its opposite extreme position where it is stored between the lower surface of the container side walls. With the lid in its stored position, the container can be translated relative to the housing causing the file divider walls and contents to rotate from their stored position where they are closely angled to the housing bottom to a substantially upright file use position. A lock is provided to lock the container to the housing preventing relative translation when in the file stored mode. The file is adaptable to contain Rolodex® type notched file cards. The open end of the housing may include a dust cover. In one embodiment of the portable file the carrying handle conceals a punch and die set for punching the slots and opening of the type normally associated with Rolodex® type file cards. Either one or more punches are provided.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
191 words
A portable file comprising: an open container having longitudinal sides, open and closed end surfaces and a bottom member; a translatable compartment having side walls translatable within said container relative thereto; a plurality of divider walls having sides and upper and bottom surfaces attached to and carried by said side walls; engagement means positioned between said side walls and each side of said plurality of divider walls, said engagement means allows a predetermined length and direction of movement of said divider walls relative to said side walls when said translatable member is translated; and hinge means interconnected between said divider walls and said base member; when said translatable compartment is translated away from said closed end surface said engagement means causes said divider walls to rotate about said hinge means and translate relative to said side walls to a position wherein the upper surface thereof are within said container and when said translatable member is translated toward said closed end surface said engagement means causes said divider walls to rotate about said hinge means and translate relative to said sides to a position wherein the upper surface extend above said container.
Claim 2
Dependent Claim
191 words
A portable file comprising: an open container having longitudinal sides, open and closed end surfaces and a bottom member; a translatable compartment having side walls translatable within said container relative thereto; a plurality of divider walls having sides and upper and bottom surfaces attached to and carried by said side walls; engagement means positioned between said side walls and each side of said plurality of divider walls, said engagement means allows a predetermined length and direction of movement of said divider walls relative to said side walls when said translatable member is translated; and hinge means interconnected between said divider walls and said base member; when said translatable compartment is translated away from said closed end surface said engagement means causes said divider walls to rotate about said hinge means and translate relative to said side walls to a position wherein the upper surface thereof are within said container and when said translatable member is translated toward said closed end surface said engagement means causes said divider walls to rotate about said hinge means and translate relative to said sides to a position wherein the upper surface extend above said container.
Claim 3
Dependent Claim
28 words
The invention as defined in claim 1 wherein said plurality of divider walls are individually removable and re-attachable to said translatable compartment and bottom member at selected locations.
Claim 4
Dependent Claim
26 words
The invention as defined in claim 1 which further comprises a removable lid member which encloses said open container and prevents translation of said translatable member.
Claim 5
Dependent Claim
53 words
The invention as defined in claim 3 further comprising a lock means for selectively securing said lid to said translatable member together when said lid encloses said container opening and said translatable member is translated away from said closed end surface and the upper surfaces of said divider walls are within said container.
Claim 6
Dependent Claim
41 words
The invention as defined in claim 3 wherein said lid member is translatable from the opening of said container by the sliding of said lid member from over the opening of said container to a location adjacent to said base member.
Claim 7
Dependent Claim
20 words
The invention as defined in claim 5 wherein said lid comprises a plurality of parallel slots interconnected by flexible material.
Claim 8
Dependent Claim
44 words
The invention as defined in claim 5 wherein said lid comprises an integral sheet of material having areas of reduced thickness along its length, said areas of reduced thickness provide a hinge between adjacent portions of said sheet of material for relative rotation therebetween.
Claim 9
Dependent Claim
35 words
The invention as defined in claim 1 wherein said translatable compartment has a plurality of slots and said divider wall sides have slot engaging tabs for removable attachment to the slots of said translatable compartment.
Claim 10
Dependent Claim
32 words
The invention as defined in claim 1 wherein said engagement means comprises elongated slots in said side walls and protrusions on each side of each of said divider walls for engagement therewith.
Claim 11
Dependent Claim
17 words
The invention as defined in claim 9 wherein said slots are angled relative to the bottom member.
Claim 12
Dependent Claim
18 words
The invention as defined in claim 10 wherein the angle of said slots is from 30° to 65°.
Claim 13
Dependent Claim
16 words
The invention as defined in claim 10 wherein the angle of said slots is substantially 45°.
Claim 14
Dependent Claim
33 words
The invention as defined in claim 1 wherein said translatable compartment extends from the open end surface of said container and further comprises a carrying handle on the extended portion of said compartment.
Claim 15
Dependent Claim
21 words
The invention as defined in claim 13 additionally comprising a lock means for selectively engaging said translatable member to said container.
Claim 16
Dependent Claim
45 words
The invention as defined in claim 13 further comprising means removably attachable to the bottom surface of said container for the removable attachment of slotted file material thereto and a punch means contained in said carrying handle for forming the slots in said slotted material.
Claim 17
Dependent Claim
27 words
The invention as defined in claim 1 wherein said plurality of divider walls have the central portion of their bottom surfaces removed forming an opening there through.
Claim 18
Dependent Claim
