Description
BACKGROUND OF THE INVENTION
The present invention relates to a portable file box and, more
particularly, to a portable file box provided with tracks on each
side to allow for suspension of file folders as well as to provide
a gripping area for moving the file box from one place to
another.
Portable file boxes, of course, are well known as shown, for
example, in U.S. Pat. No. 3,614,185. The conventional arrangement
consists of a box with side walls, end walls, a bottom wall and a
removable cover. Files can be suspended vertically in such a box on
supporting arms. The suspension device can be a generally
rectangular shaped sheet-like body which can be made from sheet
metal or molded plastic so as to be resilient in nature and readily
clamped on the side walls of the box. Another type of suspension
device for a file box is shown in U.S. Pat. No. 3,208,456 which
shows the use of a supporting frame 20 constructed from stiff wire
and formed with upright U-shaped frame sections and top parallel
horizontal rails integral with the U-shaped frame section.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a novel
suspension means for a portable file box which possesses advantages
and features not heretofore present in the prior art devices.
It is a further object of the present invention to provide a light
weight yet sturdy file box to serve the person such as a salesman
who has need to transport files in a trunk of his automobile.
It is another object of the present invention to provide a file box
with a suspension means in the form of a track on each side wall of
the box to permit suspension of a file folder while at the same
time serving to support a hinged cover.
It is still a further object of the present invention to provide a
file box with a suspension means designed to make possible the
gripping of the file box for easy conveyance from, for example, the
trunk of an automobile to an office or the like.
It is still another object of the present invention to provide a
portable file box made of a high impact plastic material to resist
damage from abuse and variations of temperature.
It is another object of the present invention to provide a file box
with a cover that is hinged and made of clear plastic to enable the
user to look into the case for the desired file, while the hinging
of the cover allows easy access to each half of the case for the
needed material instead of having to remove the entire cover for
access to the desired files.
It is a further object of the present invention to provide a file
box with a cover that will rest in a snug position on a shoulder
designed to keep the file case dust free during normal usage.
Although the present invention has particular value for a person
such as a traveling salesman, it must also be appreciated that it
is useful to anyone who wishes to eliminate soiled and damaged
paper supplies or records.
The foregoing objects and advantages have been achieved in
accordance with the present invention by providing a file box with
side walls, end walls, a bottom wall and a removable hinged cover.
The side walls of the file box are provided with tracks for
supporting suspended file folders while, at the same time,
providing a means for gripping the file box for transporting it
from one place to another. The removable cover may be transparent
in order to permit the user to view the contents and decide which
item is to be selected from the box. The cover can be hinged in the
middle so that the front or the rear portion of the box containing
the desired item is given access to the user.
BRIEF DESCRIPTION OF THE DRAWING
These and other features, objects and advantages of the present
invention will become more apparent from the following description
when taken in conjunction with the accompanying drawing which
shows, for purposes of illustration only, an embodiment of the
present invention wherein:
FIG. 1 is an isometric, exploded view of the file box and cover;
and
FIG. 2 is a partial, cross-sectional view taken through the top of
one of the side walls of the file box shown in FIG. 1.
DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
Referring now to the drawing and, in particular, to FIG. 1 there is
shown a file box and cover designated generally by the numeral 10.
The file box generally consists of side walls 11, end walls 12, and
a bottom wall 13 and can be made of any suitable material which
resists damage from abuse and variations in temperature and yet at
the same time is relatively light weight and inexpensive. I have
found that one such material is injection molded, high impact
plastic having a wood grain for appearance purposes. Integrally
provided along the top length of the side walls and end walls 11
and 12 is a flange portion designated generally by the numeral 14
and shown in greater detail in FIG. 2. This flange portion 14 is
L-shaped and consists of a horizontal portion 15 and a portion 16
projecting vertically upwardly from the outer end of member 15 as
an offset continuation of the respective end and side walls. An
L-shaped notch 17 is provided at the upper edge of the vertical
portion 16 at the side facing the interior of the box and provides
an abutment or shoulder for supporting a cover to be described more
fully hereinbelow. The flange 14 also includes a second vertically
extending portion 18 forming an extension or projection of the
inner face of side wall 11 and being considerably shorter in height
or vertical extension than the vertical portion 16. The space or
groove between the vertical portion 16 and vertical portion 18
forms a track for the downwardly extending tips of the laterally
extending file folder support arms 19 of the conventional and well
known type file folder 20.
In addition to providing an abutment for supporting the cover and a
track for the file supporting devices, the flange portion 14 in
general also provides a gripping means for a person to transport
the file case from one place to another. The gripping means is
formed by the underside of the horizontal member 15. The cover is
preferably transparent to allow inspection of the file box contents
and can be made from, for example, molded clear plastic with a
hinge 22 in the center thereof secured to the cover halves 21, 21'
by means of conventional securing devices 23 such as brads. Handles
24 can be provided on each cover half to facilitate lifting of the
cover. It can be readily seen from the drawing that the axis of the
hinge is transverse to the side walls 11. When the cover halves 21,
21' come to rest in the notch 17, the upper surface of the cover
will be substantially flush with the upper peripheral edges of the
side and end walls and the file box will be essentially waterproof
and dustproof. Overall the file box and cover arrangement will be
light weight so as to be easily transported. At the same time, the
transparent cover will allow inspection of the entire contents of
the file box and allow access to either the forward half or the
rearward half depending upon the material desired without having to
remove the entire cover.
While both the end walls 12 and side walls 11 are shown in FIG. 1
as preferably being provided with the flange portion 14 and the
notch 17 to respectively provide gripping means and an abutment for
the cover, provision of such on only one or the other would be
sufficient to provide satisfactory operation and utility of the
present invention. By the same token, although a runner need not be
provided at the end walls, unless desired, the same obviously would
be useful for storing different size suspended files. To provide
reinforcement for the walls of the file box and also to permit
thinner side and end walls to be used, reinforcement in the form of
corrugations can be employed. Further, the various edges can be
rounded to prevent stress concentration. While I have shown and
described one embodiment in accordance with my present invention,
it is to be clearly understood that the same is susceptible of
numerous changes and modifications as will be apparent to one of
ordinary skill in the art. I, therefore, do not wish to be limited
to the details shown and described herein but intend to cover all
such changes and modifications as are encompassed within the scope
of the appended claims.
