Interconnected paper clips
Abstract
A system for organizing groups or sets of related papers in
which a plurality of substantially identical, interconnectable
paper clips are provided. Each clip is capable of receiving and
retaining a single set or group of papers, and is provided with
lateral or vertical interconnecting elements for connection to a
like paper clip with the connecting elements being positioned so as
to dispose the various interconnected clips and their associated
retained sets of papers in segregated but connected, spaced-apart
parallel planes forming a terrace-like or vertical stack array. The
individual paper clips may be indexed, such as by labeling, color
coding or other indexing devices to facilitate the indentification
of the individual groups of papers in the interconnected array.

Description
BACKGROUND OF THE INVENTION
In general the present invention relates to a system for retaining
and organizing papers or documents.
Although there are all shapes, forms and sizes of paper clips, for
the most part, paper clips are designed and intended for individual
fastening of a single group or set of papers or for fastening
multiple groups of papers in an inseparable collection. For
example, with a conventional paper clip, two related sets of papers
may be each individually joined by a single paper clip. However to
join the paper sets it is necessary to either unclip one set of
papers and rejoin the consolidated set with a single clip, in which
case the sets of papers lose their separate identity entirely, or
clip the two individual sets of papers together with a single,
larger clip. In either case, the use of such prior clips is
limited, because the separate paper sets cannot be easily removed
or detached from the consolidated sets without unclipping the
individual papers of at least one set.
In many cases, it is desirable to relate these separate sets of
papers, each consisting of two or more leaves, in an organized and
interconnected, but detachable fashion, without comingling or
mixing all or some of the pages of the various sets together and
without unclipping one or more of the separately bound sets.
It is accordingly an object of the present invention to provide an
improved paper clip which overcomes the foregoing disadvantages
noted with respect to conventional paper clips and provides an
improved paper clipping system for organizing papers.
These and other objects will be more particularly brought out upon
reference to the accompanying drawings and detailed description of
particular preferred embodiments of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT
The present invention relates to a paper clipping and organizing
system for holding together a number of pieces of paper or document
pages, and more particularly to a plurality of paper clips each
being configured so as to be interconnectable with other like clips
of the system. It is the intent of the interconnectable feature of
these clips to permit related groups of papers, each held together
by an individual clip, to be attached to one another to form a
single convenient terraced or stacked paper display which can be
broken apart or added to as desired.
The use of such a clip device is best illustrated by a practical
example of its application. An accountant or bookkeeper may use the
clips to organize receipts, billings, receivables, etc. during
preparation of financial statements. The various materials are
efficiently, categorically subdivided with the individual clips,
and thereafter consolidated by interconnecting the clips in an
appropriate order. Use of the paper clip system of the present
invention permits each category or group of papers, e.g. receipts,
billings, etc., to retain its individual identity while
participating as a portion of an overall display of material
related to the particular account.
Color coding or other indexing of the clips may be employed to make
them additionally valuable by providing instantaneous
identification of each information data group in an interconnected
display of papers. Obviously the foregoing example of the system is
only one of numerous applications of this invention, and it may be
used generally in business, industry, education, medicine, etc.
wherever a need to efficiently organize documentary material
exists.
FIG. 1 illustrates the interconnectable paper clip of 10
constructed in accordance with one preferred embodiment of the
present invention. In this embodiment, clip 10 is injection molded
of a resilient plastic. This material imparts spring qualities to
the clip necessary for releasable retention of the individual
groups or sets of papers as more fully discussed herein.
A plurality of substantially identical paper clips 10 are used,
each of which is comprised of a pair of substantially planar jaws
12 and 14 joined in a base portion 16 with an opening or slot 18
between the jaws providing means for accommodating plural sheets of
paper 21 or the like. The lower jaw 12 may be stiff or rigid as in
this embodiment and provided with a jaw face 20 which guides the
paper edges 19 beneath the upper jaw 14.
Upper jaw 14 is resiliently flexible for retaining the papers by a
clamping force. An interior face 22 on base portion 16 to the rear
of the jaws abuts, limits, and aligns the paper edges. The upper
jaw 14 is molded to conform to a contour which permits it to reside
in a generally parallel relationship to the lower jaw 12 providing
a clamping line 24 in a paper receiving plane generally defined by
a slot 18 between confronting jaw faces 20 and 21. An upturned
forward lip 26 of upper jaw 14 permits the edges 19 of the sheets
of paper 21 to be easily positioned and inserted into and between
the jaws 12 and 14. Roughened or textured surfaces may be molded
into the jaw faces 20 and 21 to enhance the gripping power of the
jaws. The forward corners of both jaws may be rounded to prevent
damage to clipped papers during bending and handling.
Each paper clip 10 has integrally molded into it complementary male
and female interconnecting elements 28 and 30 respectively disposed
on opposite lateral sides of the jaws 12 and 14. In this embodiment
male element 28 is comprised of a projection 32 of rectangular
cross section which extends laterally outwardly from the base
portion 16 adjacent jaw 14 and is terminated on its outer end in a
knob-like protuberance 34. Female element 30 consists of a recessed
molded socket 36 and entry opening 38 extending laterally inwardly
of the base portion 16 adjacent jaw 12. Socket 36 and opening 38
are so dimensioned in depth to match the overall length of
projection 32 and protuberance 34 of element 28 of an adjoining
clip such that portions of the sides of the interconnecting clips
abut one another. Entry opening 38 for socket 36 is very slightly
smaller in cross section than the protuberance 34 on the male
element 28 to insure a press-fit. Additionally the socket 36 is
enlarged in dimension at its maximum depth so as to accommodate the
protuberance 34 in a snap fashion after it has been pressed through
the entry opening 38. Female element 30 is disposed in this case in
base portion 16 at its junction with lower jaw 12. To accommodate
this placement lower jaw 12 is wedge shaped with the larger section
adjoining base portion 16 to provide a relatively large cross
section of material for molding socket 36 and opening 38. The
essentially rectangular cross section of the projection 32 of the
male element 28, as it resides in and bears on the likewise
rectangular cross section of opening 38 of the female element 30,
tends to resist twisting between the clips thereby maintaining an
essentially parallel relationship between the respective groups of
papers held therein.
Male and female elements 28 and 30 are positioned on clip 10 in the
respective planes generally defined by jaws 12 and 14 and on
opposed sides of the plane defined by slot 18 between the jaws 12
and 14. This location of the interconnecting elements serves in
this embodiment as a means for spacing the plurality of
interconnected clips in elevation with the slots 18 disposed in
uniformly spaced apart parallel planes with each clip being at a
slightly different elevation than the adjacent clips as illustrated
in FIGS. 2 and 3. The connected clips are thus laterally adjacent
one another and offset in elevation so as to present the groups of
individually clipped papers in a terraced presentation as shown in
FIG. 3.
Paper clips of the type described by this invention of a size and
capacity comparable to that of common wire clips may be used singly
or joined in groups of from two to perhaps a dozen when grouping
and retaining standard eight and one-half by eleven sheets. Note in
FIG. 2 that the interconnected clips provide a relationship such
that the jaws of the successive clips present slots 18 for sheaves
of papers 17 and 23 each one at a different elevation such that
when laid upon one another the successive groups of papers maintain
a separate physical identity and may be separated at any interface
between clips for access at any time. Also it is noted in FIG. 3
that the base portions 16 of the laterally interconnected clips 46,
48 and 50 are visible beyond the upper marginal edges 52, 54 and 56
of the successive groups of paper 58, 60 and 62. Because of this
color coding of the clips, such as by molding the clips in
different colors, provides a valuable index means or referencing
system for locating a specific group of papers in the
interconnected array. A further embodiment of the index means may
be provided by a roughened upper margin surface 63 on the base
portion 16 of each clip upon which an alphabetical or numeric index
reference may be written with pencil or ball point pen to
supplement or provide an alternative to the color coding reference.
Still another embodiment of said index means is to provide label
receiving means such as stick-on labels or molded label receptacles
on the upper surface 63 of base portion 16.
FIG. 4 4 illustrates an alternate embodiment of the
interconnectable paper clip of the present invention. This
embodiment illustrates a clip 64 stamped from a sheet of metal or
plastic or a type which provides the spring qualities necessary for
clip operation. The stamping is formed into the general shape
described by the preferred embodiment previously described and
functions in a similar manner. In this embodiment, however, the
male interconnecting element 66 is comprised of a hook-like lateral
extension 68 on the one side of a flat plate-like upper jaw 70. The
female element 72 on the other hand is a contoured flange which
depends first downwardly and then laterally outwardly from a side
of a flat plate-like lower jaw 74. The male and female elements in
this case are disposed on the respective jaws adjacent a base
portion 73 joining jaws 70 and 74. A tip 76 of the male element 66
is inserted through a slotted opening 78 in the female element 72
and is rotated to position the clips in juxtaposition so that the
hook 68 completely engages the female element 72. An upper surface
80 of the outwardly extending portion 81 of female 72 functions to
support the lower surface 83 of the hook 68 and to maintain the
spaced apart parallelism of the clip jaw planes.
FIG. 5 shows a still further alternative embodiment of the
interconnectable paper clip system. Here, the complementary male
and female interconnecting elements 91 and 92 of clips 90 are
disposed to extend substantially normal or perpendicular to the
planes of the clip jaws and again on opposite sides of the plane
defined by slot 93. Elements 91 and 92 can be either vertically
aligned on each clip 90 to form a straight vertical stack of
interconnected papers, or laterally offset such that progressively
higher clips are laterally shifted to one side of the underlying
clips to create a terraced effect similar to the embodiment of FIG.
3. As in the case of clip 10 described above, clip 90 may be molded
of resilient plastic, with elements 91 and 92 being integral
therewith and shaped similarly to the male and female elements of
clip 10 to provide the same press or snap fit.
