The present invention relates to a variable volume file for documents. The present invention to reduce the disadvantages of a known file comprising a folder and a box associated therewith.
The folder is constituted by two flat parts and by a back and is, if appropriate, provided internally with a spring paper holder or with rings, or with another device for binding loose or joined sheets, such as fascicles and, in particular, printer printouts. The box, corresponding in shape and volume to the folder, is constituted by two larger bases and by three lateral surface faces, while it is without one face for the insertion of the folder.
Files of known type, when they are empty, are stored at point of production, of distribution or at the presses of the end user, and occupy the space determined by their dimensions, that is to say a constant maximum volume. Moreover, the requirement of the use of files of different capacity compels producers to manufacture files having backs of different width, with costs which are reflected in the final price of the product.
The aim of the present invention is that of providing an improved structure for a fie of the type mentioned, which makes it possible to eliminate the disadvantages listed above.
According to the present invention, a file comprises a folder and a box made individually in two separate parts, which can be partly overlapped on one another in the width direction of the bark of the folder and, respectively, of the box. Each folder part includes a flat and a back wing, internal and external respectively; each box part includes a base and lateral surface wings, internal and external respectively. Provided in the back wings of the folder and in the lateral suace wings of the box are means of sliding engagement which interact with one another for the relative movement of one part in relatiom to the other and interacting means, if any, of mutual locking of the respective parts in prefixed positions.
Advantageously, to allow a variation of the width of the back of the files the means of sliding engagement which interact with one another are constituted of a plurality of pin elements for sliding coupling and a corresponding plurality of holes for sliding of the pin elements, provided in the respective folder and box part.
Means, if any, of mutual locking which interact with one another, capable of retaining the two parts of the folder and of the box to define temporarily the width achieved with the sliding engagement means, are constituted by a multiplicity of projections facing towards the inside and a corresponding multiplicity of cavities for receiving the protections or other similar means, provided in the respective parts of the folder and of the box.
Advantageously, means of gripping the folder constituted by a hole made in the external wing of the back of the folder and by a corresponding extended aperture made in the internal wing of the back of the folder are provided.
On the outside of the external wing of the back of the folder, retaining means for identification members, if any, are provided.
The present invention will now be described with reference to a preferred embodiment thereof, on the understanding, however, that executive variations can be made without leaving the innovative concept of the present invention and with reference to the figures in the attached drawings, in which:
FIG. 1 shows a perspective view of the file according to the present invention, with the folder removed from the box;
FIG. 2 shows a partial perspective view of the folder shown in FIG. 1, and
FIG. 3 shows a plan view, on enlarged scale, of a part of the lateral surface of the box shown in FIG. 1.
With reference to the drawings, in FIG. 1 the general appearance of a file 1 according to the present invention is shown, comprising a folder 2 and a box 3. The file 1 is in particular, but not exclusively, intended for archiving printer printouts, perforated sheets and the like. To this end, a binding device or sheet holder (not shown), which is integral with the folder 2 itself or not, cam be provided inside the folder 2.
Folders of conventional type are generally constituted by two flat parts connected by a back. According to the present invention, the folder 2 is made in two separate parts 2a, 2b. Each folder part 2a, 2b includes a flat part, 20a and 20b respectively, and a back wing, internal 22a and external 21b respectively, which can be partly overlapped one on the other in the width direction of the back.
In the same manner, the box associated with the folder of a known type in question corresponds in shape and volume to the folder and is constituted of two larger bases and by three lateral surface faces, being without the fourth lateral surface face for the insertion of the folder. According to the present invention, the box 3 associated with the folder of the invention is made in two separate parts 3a, 3b. Each box part 3a, 3b includes a larger base, 30a and 30b respectively, and lateral surface wings, internal 31a and external 31b respectively, which can be partly overlapped one on the other in the width direction of the back of the box.
Provided in the external back wing 21b of the part 2b of the folder 2 (FIG. 2) and similarly in the external lateral surface wings 31b of the part 3b of the box 3 (FIG. 3) are provided pin elements, indicated generally by 4, as relative sliding engagement means of the two parts 2a, 2b of the folder 2 and, respectively, of the two box parts 3a and 3b, in the width direction of the back.
The sliding-coupling pin elements 4 engage in corresponding holes, indicated generically by 5, provided in the internal back wing 21a of the part 2a of the folder 2 and in the internal wings 31a of the part 3a of the box 3.
To retain the parts 2a, 2b of the folder 2 and, respectively, the parts 3a, 3b of the box 3 in the preselected mutual position reached, there can be provided a multiplicity of projections 6 facing towards the inside, made in the external back wing 21b of the part 2b of the folder 2 and, respectively, in the external wings 31b of the part 3b of the box 3. The multiplicity of projections 6 interacts with a corresponding multiplicity of receiving cavities 7 provided in the respective internal back wing 21a of the part 2a of the folder 2 and in the respective internal wings 31a of the part 3a of the box 3.
For gripping the folder 2, a hole 8 is made (FIG. 2) in the external back wing 21b of the part 2b of the folder and a corresponding extended aperture 9 is made in the internal back wing 21a of the part 2a of the folder.
Also provided on the surface of the external back wing 21b of the folder are means for retaining identification members, such as a label-holder 10.
