Claims
I claim:
1. A file for documents and the like and comprising a folded member
of a thin relatively stiff sheet material and having the shape of
an outer and inner envelope provided by a single rectangular sheet
with a fold line extending parallel to the short sides of said
sheet and located near the middle of the long sides of said sheet
to provide two superimposed sheet parts with free ends, a bar
having the free ends of said sheet secured thereto, a second bar
extending between said two sheet parts and adapted to bear against
the fold between said two sheets, at least one of said sheet parts
being provided with at least one slot through which a part of said
second rail penetrates thereby preventing a displacement of said
bar in a direction away from said fold.
2. A file as claimed in claim 1 wherein said first bar extending
between said two sheet parts has at least one downwardly projecting
lug, the slot of said folded member being parallel to said fold
line and having a length corresponding to said lug and being
located at a distance from said fold line which corresponds to the
height of said first bar such that said lug of the latter while the
upper portion thereof is in contact with said fold, penetrates
through said slot thereby locking said bar to said folded
member.
3. A file as claimed in claim 1 wherein said folded member is
provided with a plurality of mutually parallel fold lines for
constituting a spine of desired width, a strip of a relatively
rigid material and having the desired spine width being introduced
between said sheet parts, said strip having the same width as the
distance between two of such fold lines.
4. A file as claimed in claim 1 wherein an end closing unit
comprising a box-shaped member having one end open has its sides
inserted in the space between the sides of said two envelopes and
its bottom inserted between the spines of said envelopes.
5. A file as claimed in claim 4 wherein the bottom of said end
closing unit is extended to provide a portion which extends outside
the spines of said envelopes, said portion being folded over an
underlying transverse of the outer envelope to lock the closure
unit in said envelopes.
6. A file as claimed in claim 1, wherein said first bar which bears
against said fold is threaded through spaced apart slots adapted in
one envelope and extends perpendicular to said fold such that one
part of said first bar will be situated intermediate the sheet
parts while another part is situated outside the same.
Description
This invention refers to a file for documents and the like and has
for its main object to provide a file which may be manufactured at
low costs and which offers the possibility of arranging partition
sheets, adjustable labels and the like as well as pockets in the
file sides for the purpose of storing papers or the like or for
stiffening up said sides, the attachment of the suspension bars
being extremely simple and efficient.
To obtain these and other advantages the file has the
characteristics pointed out in the appended claims.
The invention will now be described more in detail, reference being
had to the accompanying drawings in which:
FIG. 1 is a partially broken perspective view of a preferred
embodiment of the invention.
FIG. 2 is a perspective view of a die closure unit in a partly
folded position.
FIG. 3 is a perspective view, showing the side closure according to
FIG. 2 during insertion in the file.
FIG. 4 is a side view of the file according to FIG. 1.
FIG. 5 is a partly broken perspective view of the bottom portion of
the file according to FIG. 1 but being only provided with a bottom
inlay instead of the side closure unit.
FIG. 6 shows in perspective the upper portion of one file side,
having attached to its rail a suspension strip.
FIG. 7 shows in perspective the upper portion of the other file
side, having attached to its rail a combined label holder and
suspension device.
FIG. 8 is a fragmentary perspective view of a file side with a side
stop for one of the rails of the file and
FIG. 9 is a fragmentary perspective view showing a file side and a
rail attached thereto.
The file according to FIG. 1 comprises a folded member in the shape
of a double envelope made of a relatively thin but rigid sheet
material such as cardboard, plastic or the like. This folded member
is generally designated 1 and is made of a rectangular sheet, which
is folded along a first folding line 2, parallel to the short sides
of the sheet and located near the middle of the long sides such
that two superimposed sheet parts of approximately the same length
are generated. This composite member is folded along parallel
folding lines 3 and 4 to constitute a bottom portion and two file
sides. The free ends of the sheet parts are formed to channelled
end portions 5a, 5b having their open sides facing each other. The
folded member thus comprises an inner pocket 6 and an outer pocket
7 with intermediate spaces 8. As will be clear from the following
description this construction not only offers the possibility of
making a stiff file from a thin material but also facilitates the
attachment of one of the suspension bars or rails, generally
designated 9 at the same time as the spaces 8 may be used for
storing documents, insertion of inlays and the like.
The suspension bar 9, which is of a conventional design and has
downwardly projecting side stops 10 is introduced between the two
superimposed sheet parts such that it bears against the fold at 2.
The other suspension bar 11 is preferably extruded from a
transparent plastic material and has a T-shaped downwards open
longitudinal groove 12 serving to receive the end portions 5a, 5b
as well as the upper vertical side portions of the sheet parts as
clearly shown in FIG. 1. The bar is thus secured to the file side
by merely sliding the same over the upper portion of said file
side.
When it is desired to provide the file with an end closure a
separate closure unit according to FIG. 2 may be used. The
illustrated closure unit is made from a single sheet and comprises
a bottom part 16 the length of which exceeds the length of the file
such that a projecting tongue 17 is generated. Stiffening parts
18a, 18b are integral with the bottom part and are intended to be
folded along folding lines to form vertical sides as shown. Side
parts 19a, 19b having also bottom parts 20a, 20b are connected to
an end part 21 and by folding the parts as shown in FIG. 3 a box
shaped unit having an extended bottom portion is generated. This
unit may be connected to the file in a very easy manner by merely
inserting the parts 19a, 19b, 16 18a, 18b between the sheet parts
of the file sides with the bottom parts 20, 16, 17 resting upon the
lower bottom of the file. As previously mentioned the tongue 17
projects outside the file when the unit 15 is fully inserted and by
folding said tongue according to FIG. 4 the end closure is secured
in its position without the need of any separate securing
means.
The file just described has a bottom of a certain width. It is,
however, possible to vary said width within broads limits. As
appears from FIG. 5 the folded file member may have for instance
three bottom folding lines 3, 4 and 22. If the file is folded along
the central folding line 22 a very thin file suitable for the
storage of a few documents is obtained. In this condition the file
is also well suited for storage and transport. When it is
necessary, however, to use the file for a greater number of
documents the file is folded along folding lines 3 and 4 and by
inserting between the upper and lower bottom of the file a
relatively stiff strip 23 of a certain width a rigid bottom having
the desired width may be obtained. When a plurality of such folding
lines are arranged it is thus possible to obtain any desired width
by merely introducing a strip of the desired width.
As appears from FIG. 6 and 8 the side stops of bar 11 or 9 may
consist of separate units received in corresponding openings in the
bar. By inserting an end portion of a suspension strip 24 between
or over the file end portions 5a, 5b before the bar 11 is slid over
said portions also said suspension strip may be easily secured to
the file. The suspension strip 24 may be provided with perforations
25 and folding lines 26 to obtain different means for holding
articles such as documents.
The bar 9 may be easily secured to the file by providing in the
latter spaced apart vertical slots 27a, 27b permitting the bar to
be thread in the manner illustrated in FIG. 7. The part of the bar
which is located intermediate these slots 27a, 27b, may be used to
guide a holder 28 having a transparent hollow label receiving
portion 29 as well as a suspension device 30, 31 for documents and
the like.
The side stop 32 shown in FIG. 8 is provided with an attachment
portion 33 held by friction in the hollow bar, and a projecting
portion 34 forming the side stop. Additionally two resilient
tongues 35a, 35b are arranged to hold the side stop unit secured to
the folded file member by embracing its sheet parts.
An extremely simple and useful bar attachment construction is shown
in FIG. 9. The bar 9 has downwardly projecting spaced apart lugs 36
each intended to project through a slot 37 provided in one sheet
member of the folded file member. To remove the bar 9 it is only
necessary to tilt it in the direction of the arrow in FIG. 9 and
the attachment of course takes place by inserting the bar and
tilting it in the opposite direction.
