BRIEF SUMMARY
FIELD OF THE INVENTION
The invention relates to a file with a modular construction, according to the preamble of the independent patent claim.
BACKGROUND OF THE INVENTION
From DE-U-9301485 there is known a file with a modular construction. It comprises a back section with laterally pivotable wings on the file backs and the file covers can be connected to the wongs by way of slider strip. For this the file covers and file backs comprise a multitude of recesses arranged on a line parallel to the rear edge and arranged at roughly uniform distances. The recesses comprise a rectangular introduction opening and a slot-like extension connecting thereto. The sliders are provided with the same multitude of T-shaped locking elements at the same distances. When the file cover is applied on the corresponding wing, the slider strip is fastened in that its T-shaped locking element with the transverse crosspiece is inserted through the introduction openings and is pulled into the locking slot with the longitudinal arm. The slider strip externally is arranged on the file cover and file back and engages inwardly with the locking element. This is necessary so that on normal use the locking elements are not damaged, since the transverse crosspiece of the T-shaped locking elements project beyond the surface of the cover. The file or clamp mechanism is connected to the back section. This has the effect that for every type of file, according to the width and clamp standard, European or American, a complete back section must be manufactured.
SUMMARY OF THE INVENTION
It is the object of the invention to provide a modularly constructed file which enables the back width, the filing mechanism and the latching device to be adapted to differing file thicknesses and clamp standards in the simplest manner. It is to comprise almost no protruding parts which on normal handling may easily be damaged.
This object is achieved by the invention specified in the patent claims.
The advantages of the invention lie in the fact that each file may be put together exactly according to the desired requirements from a minimal number of differing elements. Each file may also later be adapted in the simplist manner to new requirements and wishes. Each of its elements may be individually exchanged. For example the clamp mechanism or the colour of the file cover or the width of the back section may be changed alone or in a combined manner.
BRIEF DESCRIPTION OF THE DRAWINGS
The file according to the invention is hereinafter described in the context of the drawings. There are shown:
FIG. 1 an exploded drawing of the file;
FIG. 2 a representation of the joined together file;
FIG. 3 a view of a retaining strip with the file mechanism and securing elements; and
FIGS. 4a to c show an embodiment form of a back section with an accompanying inscription strip.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
In FIG. 1 all important parts of a file according to the invention are shown in an exploded drawing. The file consists basically of a back section 1 with laterally attached wings 2, 3, a file cover 4, a file back 5, a first retaining strip 7, 8 with a clamp mechanism 71, 81 and a second retaining strip 6.
The back section 1 is pivotably connected with first film-like hinge 12 to the first wing 2 and with a second film-like hinge 13 to the second wing 3. Each wing 2, 3 is provided with at least in each case two L-shaped first guide strips 21-24 and second guide strips 31-34 running parallely opposite one another and distanced. In the shown preferred embodiment form the first wing 2 comprises parallel guide strips in a paired arrangement, and specifically two lower 21, 22 and two upper 23, 24 L-shaped guide strips directed opposing one another. Between the lower 21, 22 and the upper 23, 24 guide strips there exists an intermediate space free of guide strips. The L-shaped guide strips lying opposite one another face opposite one another with the free arm so that between the free arms and the surface of the respective wing 2, 3 there is present a groov
