Flexible dividers for lateral shelf filing
Abstract
The invention is an improvement in lateral shelf filing. For the
purposes of this invention a stationary or roll-out shelf is
provided with a plurality of spaced and horizontally aligned slots
in its bottom or base panel, with the slots spaced a predetermined
distance from the rear of that panel. Additionally, the rear panel
of the shelf comprises a plurality of pairs of vertically spaced
key slots with the members of each pair being aligned with each
other as well as a corresponding slot in the base panel. At least
one flexible divider is associated with the shelf. The divider is
formed with a pair of vertically aligned key tabs on its rear edge
adapted for interlocking with a pair of key slots to provide a
bayonet-type mounting. A third tab is provided along the bottom
edge of the divider for insertion into one of the slots in the base
panel. The divider is adapted to be mounted to the rear panel so
that its third tab faces up or down, whereby when the third tab
faces down the divider can be fanned on top and when it faces up
the divider can be fanned from the front.

Description
This invention relates to lateral shelf filing and in particular to
resilient flexible shelf dividers for lateral shelf filing.
In the business world of today, a great deal of information is
disseminated in the form of letters, memoranda, manuscripts and
monographs, advertising literature, and the like. This material is
usually placed in indexed folders to facilitate filing and
retrieval. These folders in turn are commonly stored in file
cabinet drawers or on open shelves. Lateral filing is utilized with
stationary or roll-out shelves.
In lateral filing the folders and binders are positioned vertically
side by side and oriented so that they extend from front to back.
In this type of filing the folders are indexed on the top or at the
front. The indexing is achieved by providing fixed or removable
tabs at the top or front edge of one of the two halves of the
folder, with the tabs being labelled to indicate the contents of
the folders.
In lateral filing the verticaly extending end walls of the shelf
function as end stops for the filed material. Bookends may be
provided to compress filed folders together so as to keep them
erect. Preferably, however, vertical dividers are attached in some
way to the horizontal shelf to provide open compartments for the
stored materials and also to maintain them in an erect
position.
However, dividers heretofore employed have not been satisfactory.
For one thing dividers are not known which are equally satisfactory
for filing systems employing side indexing and filing systems
employing top indexing. Other problems have been encountered with
open filing shelves or drawers which have dividers that are
permanently attached. For one thing, the dividers cannot be
adjusted to suit the users' needs. Of course, adjustable dividers
have been provided, but these are difficult to handle or may
require the use of auxiliary fastener means such as screws for
securing them in place. A more prevalent problem stems from the use
of dividers that are quite stiff. In such case, when a large amount
of material is inserted between the dividers so that the material
is tightly compressed, it is difficult to fan or separate the
material to read the tabs or labels. Also it is difficult to insert
or remove selected material from the shelf or drawer. Metal
dividers also increase the chance of injury to personnel,
particularly from rough, sharp or burred edges.
Accordingly, an object of the present invention is to provide a
simple, practical and economical lateral filing unit having
dividers which overcome the aforementioned problems.
Another object of the present invention is to provide a lateral
filing shelf unit having new and improved dividers which are
flexible, light weight, and are easily removed or attached.
Still another object of the present invention is to provide lateral
filing shelf dividers which may be easily adjusted to the user's
needs and are adapted for both top and front indexing systems.
A further object of the present invention is to provide a lateral
filing shelving unit having flexible and resilient dividers that
facilitate the spreading or fanning of filed materials and also
insertion and removal of the same or other materials, the dividers
being adjustable for top or side indexing.
The foregoing and other objects are achieved by a lateral filing
shelving unit comprising one or more stationary or pullout shelves
and at least one lateral divider associated with each shelf. Each
shelf includes a base panel and a rear panel, with the base panel
having a number of slots or indentations formed therein which are
spaced from the back panel a predetermined distance. The rear panel
of the cabinet section comprises a number of pairs of vertically
aligned key slots, with each such pair being substantially aligned
with one of the slots or indentations formed in the base panel.
Each divider is made of a flexible material and is provided with a
pair of aligned key tabs that are constructed and located so that
they are capable of slidably cooperating with a pair of key slots
to slidably interconnect the divider and rear panel. A third tab is
provided on the divider for cooperating with a slot or indentation
in the base panel only when the divider is disposed in a first
orientation.
Other features and many of the attendant advantages of the
invention are described or rendered obvious by the following
detailed description which is to be considered together with the
accompanying drawings wherein:
FIG. 1 shows an exploded perspective view illustrating a preferred
embodiment of the invention;
FIG. 2 shows a perspective view similar to FIG. 1 but showing the
two dividers assembled for use;
FIG. 3 shows a cross-sectional view taken along line 3--3 of FIG.
2;
FIG. 4 is a top view of the rear end of one of the dividers shown
in FIG. 1 showing details of one of its two locking tabs;
FIG. 5 is a fragmentary side view illustrating details of
construction of the locking tab shown in FIG. 4; and
FIG. 6 is an enlarged cross-sectional view taken along line 6--6 of
FIG. 3.
In the drawings like numerals designate like parts.
Referring now to FIG. 1, the illustrated apparatus comprises a
metal shelf assembly 2 of the type commonly employed in roll-out
shelf filing cabinets. Although not shown, it is to be understood
that roll-out suspension arms of conventional design are used to
mount the shelf assembly to a filing cabinet. Of course, for the
purposes of this invention the shelf assembly 2 need not be mounted
for roll-out movement but instead may be fixed.
Still referring to FIG. 1, the shelf assembly 2 comprises a base
panel 12, a rear panel 14 and opposite side panels 16. Associated
with the shelf assembly are lateral dividers 18A and 18B.
Preferably, but not necessarily, the base and rear panels 12 and 14
are formed from a single sheet of metal which is bent along a
predetermined line as shown at 13 to that the two panels extend at
a right angle to each other. Additionally for reinforcement
purposes the forward edge of base panel 12 and the upper edge of
rear panel 14 are bent to form flanges 15 and 17. Side panels 16
are joined to the base and rear panels, preferably by welding, so
as to form an integral structure. The side panels are parallel to
each other and extend at right angles to panels 12 and 14.
Base panel 12 is provided with a plurality of elongate parallel
slots 20, the purpose of which will be described hereinafter. The
slots 20 are all aligned with one another, being spaced the same
predetermined distance from the rear edge of base panel 12. A
U-shaped channel member 22 extends beneath slots 20 and is welded
to the undersurface of base panel 12 to provide structural support
whereby to prevent the front portion of the base panel from sagging
under the weight of stored filing folders.
Referring now to FIGS. 1 and 2, rear panel 14 is provided with a
plurality of pairs of identical key slots 30A and 30B which
consists of rectangular apertures 32, with upper and lower
extensions in the form of narrow slots 34 and 35. The width (ie.
the horizontal dimension as seen in FIG. 1) of slots 34 and 35 are
the same, while the length of (ie. the vertical dimension as seen
in FIG. 1) of slots 35 is greater than that of slots 34. Each slot
30A is vertically aligned with a corresponding slot 30B, and each
pair of aligned slots 30A and 30B is aligned with a corresponding
slot 20 of base panel 12. Slots 30B are spaced the same
predetermined distance from the bottom of rear panel 14 and slots
30A are spaced vertically the same predetermined distance from
slots 30B.
The dividers 18 are made of plastic material and each comprises a
planar body 38 of generally rectangular shape, a pair of key tabs
40A and 40B and a restraining tab 42. The body 38 has flat opposite
side surfaces which terminate in rounded or blunt edges 43 at the
top, bottom and front sides. Additionally its two front corners are
preferably rounded as shown at 44. These rounded edges and corners
reduce the likelihood of injury to users. Each divider is also
formed with one or more large apertures 45 for the purpose of
giving the body 38 greater flexibility and also to cut down the
overall weight and materials cost. Apertures 45 also function as
finger holes to facilitate attachment and removal of the divider
with respect to the shelf assembly.
Referring now to FIGS. 1 and 4-6, the key tabs 40A and 40B are
identical and are integrally formed with the planar body 38 along
the rear verticle edge of the latter. Tabs 40A and 40B are located
equal distances from the upper and lower horizontal edges
respectively of divider body 18. This distance is preferably made
slightly less than the distance between the bottom of slots 35 of
the lower key slots 30B and the juncture of base panel 12 and rear
panel 14. Additionally, tabs 40A and 40B are spaced from one
another a distance equal to the distance between the apertures 32
of a pair of key slots 30A and 30B. The rear edge of the planar
body 38 is flat and is also indented between tabs 40A and 40B as
shown at 45 in FIG. 3. Formed integral with the body 38 on its
opposite sides at its rear edge are right angle flanges 46 and 47.
These flanges are reinforced by a plurality of vertically spaced
webs 48 formed integral with both the flanges and body 38 and
terminate at indented portion 45 which has a narrower edge flange
49 on each side of body 38. The rear edges of flanges 46 and 47 are
flat and flush with the flat rear edge of divider body 38.
Still referring to FIGS. 1 and 4--6, the tabs 40A and 40B comprise
flat planar body portions 50 that preferably are of the same
thickness as the divider body 38. In any event, however, their
thickness is slightly less than the width of slots 34 and 35. These
tab body portions are rectangular and preferably their edges and
their rear corners are rounded so as to avoid likelihood of injury
to the user and also to facititate insertion in slots 34 and 35.
The length i.e. the vertical dimension as seen in FIGS. 1 and 5) of
each tab body portion 50 is made greater than the corresponding
dimension of the center apertures 32 of the key slots but less than
the overall distance between the opposite ends of each pair of
narrow slots 34 and 35. The depth or lateral dimension of each tab
body portion 50 is substantially greater than the thickness of rear
panel 14. In this connection it is to be appreciated that the upper
and lower edge portions of divider body 38, the flanges 46 and 47
project far enough so that the distance between their outer edges
is greater than the width of the center apertures 32 of the key
slots.
Formed integral with the opposite side surfaces of each tab body
portion 50 are two ears 54. These ears may be solid but preferably
as shown each ear is U-shaped and comprises a rib or a flange 56
connecting two parallel legs 57 and 58. The latter are tapered,
having a triangular or wedge configuration in plan view (see FIG.
4). Flanges 56 are spaced from flanges 46 and 47 and are curved (as
viewed in side elevation, FIG. 5) so as to present a concave
surface to the flat rear surface of the adjacent flange 46 and 47.
The ears 54 are located so that the minimum distance of the gap or
groove 55 formed between flanges 56 and the adjacent flanges 46 and
47 is about equal to the thickness of rear panel 14. The vertical
distance between the upper and lower surfaces of legs 57 and 58
respectively is slightly less than the vertical dimension of the
apertures 32 of the key slots. Also the flanges 56 project
laterally from the tab body portions so that the overall distance
between their outer edges is slightly less than the width of
apertures 32 but greater than the width of slots 34 and 35. The
body portions of tabs 40A and 40B are spaced from one another so
that (a) the distance between their upper and lower edge
respectively is less than the distance between the upper end of a
slot 34 of an upper key slot 30A and the lower end of a slot 35 of
a corresponding lower key slot 30B, and (b) the distance between
their lower and upper edges respectively is greater than the
distance between the lower end of a slot 35 of an upper slot 30A
and the upper end of a slot 34 of a lower key slot 30B. Also the
corresponding ears 54 on each pair of locking tabs 40A and 40B are
spaced from one another so that (a) the upper surface of leg 57 of
the upper ear and the lower surface of the leg 58 of the lower ear
are spaced apart slightly less than the upper edge of aperture 32
of a key slot 30A and the lower edge of aperture 32 of the
corresponding aligned slot key slot 30B, and (b) the lower surface
of leg 58 of the upper ear and the upper surface of the leg 57 of
the lower ear are spaced apart slightly more than the lower edge of
aperture 32 of key slot 30A and the upper edge of aperture 32 of
the corresponding key slot 30B.
Referring again to FIGS. 1-3, one of the horizontal edges of each
divider 18 is provided with a restraining tab 42. Restraining tab
42 is integrally formed with divider body 38 and projects beyond
the edge of the divider body a distance about equal to the distance
between the bottom end of slot 35 of a key slot 30B and the base
panel 12. The length of tab 42 is slightly less than that of the
slots 22. Tab 42 is spaced from the rear edge of the divider
flanges 46 and 47 a distance equal to the distance of slots 20 from
rear panel 14.
Dividers 18 may be made of any strong, durable and flexible
material. Good results have been found to occur where the dividers
are molded from ABS resins although it will be obvious to one
skilled in the art that the dividers may be formed of other
moldable plastics.
The above-described dividers may be installed in either of two
positions, depending upon whether a top or side indexing mode of
filing is contamplated. However, in both positions attachment of
the dividers to the rear panel is accomplished in the same way.
First the divider is held so that its two locking tabs 40A and 40B
are aligned with a pair of vertically aligned key slots 30A and
30B. Then the tabs are inserted through the aligned key slots, with
the oversized aperture section 32 of the key slots allowing the
ears on the locking tabs to penetrate through rear panel 14. The
tabs are inserted far enough from the rear surfaces of flanges 46
and 47 to engage panel 14, and then installation is completed by
pushing the divider downward so that the ears can interlock with
the panel (as shown in FIG. 6) along opposite sides of the slot
extensions 35 of the two key-slots. The curved surfaces of flanges
56 facilitate the downward movement required to interlock tabs 40
and slots 30 while the minimum width of grooves 55 assures that
those curved surfaces and the rear surfaces of flanges 46 and 47
will frictionally engage the opposite sides of panel 14 and thereby
hold the divider in place.
Depending upon whether top or side indexing of files in
contemplated, the divider is installed with its restraining tab 42
down or up. When installed with restraining tab 42 in the down
position, the tab 42 interlocks with a slot 20. It is to be noted
that the spacing of the locking tabs 40A and 40B and the spacing
and locations of the key slots 30A and 30B are such that when the
divider is interlocked with rear panel 14, a gap is left between
the bottom edge of the divider body and base panel 12. This is to
prevent any problems due to possible misalignment of the base and
rear panels or bucking or warping of the base panel.
The capacity of mounting the dividers with their restraining tabs
up or down gives rise to two different actions and certain
advantages. Referring now to FIG. 2, if the folders to be filed are
top indexed, the divider is mounted so that its restraining tab 42
is engaged in a slot 20, as shown by divider 18A. When so mounted,
the divider is capable of a fanning action (shown in dotted lines)
which may be characterized as a vertical V action since it can be
fanned by flexing it to one side or the other relative to its
bottom and rear edges which are held fixed by virtue of engagement
of its locking tabs 40A and 40B and its restraining tab 42 with the
rear and base panels respectively. This fanning action facilitates
separating files for purposes of identification and also removal
and insertion. An added advantage of locking the tab 42 to the base
panel is that the top indexed folders cannot slump or slide under
the divider. For front indexed folders, the dividers are mounted
with their restraining tabs 42 facing up, as shown in FIG. 1 by
divider 18B. This permits a fanning action (shown in dotted lines)
which may be characterized as a lateral V action since the divider
can be fanned by flexing it to one side or the other relative to
its rear edge which is anchored to rear panel 14. This action
facilitates laterally fanning front indexed folders for
identification and removal or insertion.
The present invention has numerous other advantages. The dividers
may be molded of various plastics by conventional molding
techniques at relatively low cost. The use of plastic material
allows the dividers to be colored throughout, thus eliminating the
problem incurred with metal dividers of having to repaint to cover
scratches. The use of plastic also permits adequate control of
flexibility and resiliency. More important, the dividers are easily
installed and removed, thereby facilitating increasing or
decreasing the spacing between them. In this connection, it is
noted that key slots of other configurations may be used, with
corresponding changes in tab configuration being made to assure
proper mating. Thus for example, the oversized central portions 32
of the key slots may be made square, oval, circular, etc. It also
is contemplated that more than two locking tabs may be provided on
each divider, but this is not preferred since it increases mold
costs and necessitates one or more additional rows of key slots to
be provided in the rear panel of shelving unit. Also, as previously
noted, the invention is applicable to fixed as well as roll-out
shelves. In the case of fixed shelf units, the base and rear panels
may be formed separately from one another, e.g., the rear panel may
be an integral part of an open cabinet and the base panel may be
separate shelf removably mounted to the cabinet. It also is
contemplated that the ears on the opposite sides of tabs 40A and
40B may be made a solid side extension, ie., the space between the
legs 57 and 58 and flange 56 may be filled in solid so that each
ear is a solid wedge shaped integral side extension of the planar
body of the tab. This tapered or wedge shape, like that of the legs
57 and 58 facilitates insertion of the key locking tabs into the
key slots.
Since certain obvious changes may be made in the illustrated
embodiment of the device without departing from the scope of the
invention, it is intended that all the matter contained herein be
interpreted as illustrative and not in a limiting sense.
